Luís and João Batalha: Fermat's Library and the Art of Studying Papers | Lex Fridman Podcast #209

the following is a conversation with luiz and joao batala brothers and co-founders of firma's library which is an incredible platform for annotating papers as they write on the formats library website justice pierre de fermat scribbled his famous last theorem in the margins professional scientists academics and citizen scientists can annotate equations figures ideas and write in the margins for mars library is also a really good twitter account to follow i highly recommend it they post little visual factoids and explorations that reveal the beauty of mathematics i love it quick mention of our sponsors skiff simply safe indeed netsuite and for sigmatic check them out in the description to support this podcast as a side note let me say a few words about the dissemination of scientific ideas i believe that all scientific articles should be freely accessible to the public they currently are not in one analysis i saw more than 70 of published research articles are behind a paywall in case you don't know the funders of the research whether that's government or industry aren't the ones putting up the paywall the journals are the ones putting up the paywall while using unpaid labor from researchers for the peer review process where is all that money from the paywall going in this digital age the costs here should be minimal this cost can easily be covered through donation advertisement or public funding of science the benefit versus the cost of all papers being free to read is obvious and the fact that they're not free goes against everything science should stand for which is the free dissemination of ideas that educate and inspire science cannot be a gated institution the more people can freely learn and collaborate on ideas the more problems we can solve in the world together and the faster we can drive old ideas out and bring new better ideas in science is beautiful and powerful and its dissemination in this digital age should be free this is the lex friedman podcast and here's my conversation with luiz and joao batala luis you suggested an interesting idea imagine if most papers had a backstory section the same way that they have an abstract so knowing more about how the authors ended up working on a paper can be extremely insightful and then you went on to give a backstory for the feynman qed paper this is all in a tweet by the way we're doing tweet analysis today how much of the human backstory do you think is important in understanding the idea itself that's presented in the paper or in general i think this gives way more context to the work of of scientists i think people a lot of people have this almost kind of romantic misconception that the way a lot of scientists work is almost as the sum of eureka moments where all of a sudden they sit down and start writing two papers in a row and the papers are usually isolated and when you actually look at it it's the papers are you know chapters of a way more complex uh story and the definement qed paper is a good example so feynman was actually going through a pretty dark phase before writing that paper it was he lost enthusiasm with physics and doing physics problems and there was one time when he was in the cafeteria of cornell and he saw a guy that was throwing flights in the air and he noticed that there was when the plate was in the air there were two movements there the plate was wobbling but he also noticed that the the cornell symbol was rotating and he was able to figure out the equations of motions uh the equations of motions of those uh plates and that uh led him to kind of think a little bit about electron orbits in relativity which led to the paper of about quantum electrodynamics so that kind of reignited his interest in physics and and and ended up publishing the paper that led to the his nobel prize basically and i think it's it's there are a lot of really interesting backstories about papers that readers never get to know friends we did a couple of months ago um an ama around a paper a pretty famous paper the gans paper with ian goodfellow and so we did an ama where everyone was could ask questions about the paper and ian was responding to those questions you also he was also telling the story of how he got the idea for that paper in a bar so there was also an interesting and a back story i also read a book by cedric villani uh these cedric velani is this mathematician the fields medalist and in his book he tries to explain how he got from like a phd student to the fields metal and he tries to be as descriptive as possible every single step how we got to the fields metal and it's interesting also to see just the amount of random interactions and discussions with other researchers sometimes over coffee and how it led to like fundamental breakthroughs and some of his most important papers so i think it's super interesting to have that context of of the backstory well the ian goodfellow story is kind of interesting and perhaps that's true for feynman as well i don't know if it's romanticizing the thing but it seems like just a few little insights and a little bit of work does most of the leap required do you have a sense that for a lot of the stuff you've looked at just looking back through history uh it it wasn't necessarily the grind of like andrew wiles of the females last theorem for example it was more like a a brilliant moment of insight in fact ian goodfellow has a kind of sadness to him almost in that at that time in machine learning like at that time especially in uh for gans you could code something up really quickly on a single machine and almost do the invention go from idea to uh experimental validation and like a single night a single person could do it and now there's kind of a sadness that a lot of the breakthroughs you might have in machine learning kind of require large-scale experiments so it was almost like the early days so i wonder how many low-hanging fruit there are in science and mathematics and even engineering where it's like you could do that little experiment quickly like you have an insight and a bar why is it always a bar but you have an insight at a bar and then just implement and the world changes it's it's a good point i think it also depends a lot on the maturity of the field when you look at a field like mathematics like it's a pretty mature field uh feels like machine learning um it's it's growing pretty fast and um it's actually pretty pretty interesting i i looked up like the number of new papers on archive with the keyword machine learning and like 50 of those papers have been published on in the last 12 months so you can see just the same zero five zero fifty percent so you can see the the the the magnitude of growth in that field and so i think like as fields mature like those types of moments i think naturally uh are less frequent um it's just a consequence of that the other point that is interesting about the backstory is that it can really make it more memorable in a way and and by making it more memorable it's it kind of sediments the knowledge more in your mind i remember also reading the sort of the backstory to to dijkstra's shortest path algorithm right where he came up with it uh essentially while he was sitting down at a at a coffee shop in amsterdam and he and he came up with that algorithm over 20 minutes and one interesting aspect is he didn't have any pen or paper at the time and so he had to do it all in his mind and so there's only so much complexity that you can handle if you're just thinking about it in your mind and that like when you think about the simplicity of dijkstra's shortest path finding algorithm it's you know knowing that backstory helps sediment that algorithm in your mind so that you don't forget about it as easily it might be from you that i saw a meme about texture it's like he's trying to solve it he comes up with some kind of random path and then it's like my parents aren't home and then he does uh he figures out the algorithm for the shortest path i strike through words to convey memes but that's hilarious i don't know if it's in post that we construct stories that romanticize it apparently with newton there was no apple especially when you're working on problems that have a physical manifestation or a visual manifestation it feels like the world could be an inspiration to you so it doesn't have to be completely in on paper like you could be sitting at a bar and all of a sudden see something and a pattern will will spark another pattern and you can visualize it and rethink a problem in a particular way of course you can also load the math that you have on paper and always carry that with you so when you show up to the bar some little inspiration could be the thing that changes it is there any other people almost on the human side whether it's physics with feynman derock einstein or computer science touring anybody else any backstories that you remember that jump out because i'm also referring to not necessarily these stories where something magical happens but these are personalities they have big egos some of them are super friendly some of them are like self-obsessed some of them have anger issues some of them how do i describe feynman but he appears to uh have a appreciation of the beautiful in all its forms it has a wit and a cleverness and a humor about him so it does that come into play in terms of the construction of the science well i think you brought up newton newton is it's a good example also to think about his backstory because you know there's a certain backstory of newton that people always talk about but then there's a whole another aspect of him that is also a big part of the person that he was but you know he was really into alchemy right and that he spent a lot of time thinking about that and writing about it and he took it very seriously he was really into bible interpretation and trying to predict things based on the bible and so there's also a whole backstory then and of course you need to look at it in the context that and the time that when newton lived um but a but it adds to his personality and it's important to also understand those aspects then maybe you know uh i'm not people people are not as proud to teach to little kids but it's important it was part of who he was and and maybe without those he who knows what he would have done otherwise so well the the cool thing about alchemy i don't know how it was viewed at the time but it almost like to me symbolizes dreaming of the impossible like most of the breakthrough ideas kind of seem impossible until they're actually done it's like achieving human flight it's not completely obvious to me that alchemy is impossible or like putting myself in the mindset of the time and perhaps even still every everything that uh you know some of the most incredible breakthroughs are would seem impossible and i wonder the value of believing almost like focusing and dreaming of the impossible such that it is actually is possible in your mind and that in itself manifests whether the accomplishing that goal or making progress in some unexpected direction so alchemy almost symbolizes that for me i distinctly remember having the same thought of thinking you know when i learned about atoms and that they have protons and electrons i was like okay to make gold you just take whatever has an atomic weight below it and then shove another proton in there and then you have a bunch of gold so like why don't people do that it seemed like conceptually is like you know this sounds feasible you might be able to do it and you can actually it's just very very expensive yeah yeah exactly exactly so in a sense we do have alchemy and maybe even back then it wasn't as crazy that he was so into it but good people just don't like to talk about that as much yeah but newton in general is a very interesting fellow anybody else come to mind in terms of people that inspire you in terms of people that you just are happy that they have once or still exist on this earth i think i mean freeman dyson for me yeah freeman dyson was was i've had a chance to actually exchange a couple of emails with him it was probably one of the most humble scientists that i've ever met and that had a a big impact on me we were trying we're actually trying to convince him to annotate a paper on fermat's library and i sent him an email asking him if you could annotate a paper and his response was something like i have very limited knowledge i just know a couple of things about certain fields i'm not sure if i'm qualified to do that that was his first response and and this was someone that should have won an opera fry's and worked on a bunch of different fields um did some really really great work and then just the interactions that i had with him every time i asked him a couple of questions about his papers and uh he always responded saying i'm not here to answer your questions i just want to open it more questions um and uh so that had a big impact on me it was like just an example of an extremely humble yet accomplished uh scientist and feynman was also a big big inspiration in the sense that he was able to be you know again extremely talented and and scientists but at the same time socially he was able to to he was also really smart from a social perspective and he was able to interact with people it was also a really good teacher and was also to did a awesome work in terms of um explaining physics to to the masses and motivating and getting people interested in physics and that for me was was also a big inspiration yeah i like the childlike curiosity of some of those folks like you mentioned freeman i have daniel kahneman i got a chance to meet and interact with some some of these truly special scientists what makes them special is that even in uh older age they're still like there's still that fire of childlike curiosity that burns and uh some of that is like not taking yourself so seriously that you think you've figured it all out but almost like thinking that you don't know much of it and that's like step one in having a great conversation or collaboration or exploring a scientific question it's cool how the very thing that probably earned people the nobel prize or or work that's seminal in some way is the very thing that still burns even after uh they've won the prize it's cool to see and they're rare humans it seems and to that point i remember like the last email that i sent to freeman dyson was like in his last birthday he was really into number theory and primes so what i did is i took like a photo of him a picture and then i turned that into like a giant prime number so i converted the picture into a bunch of one and eight and then i moved some numbers around until it was a prime um and then i sent him that also the the visual like it still looked like the picture it's made up of a problem that's tricky to do it's hard to do it looks harder than it actually is so the the way you do it is like you convert the darker regions into eights and the lighter regions in ones and then there's just keep flipping yeah but there's like some primality tests that are cheaper from a computational standpoint yes but what it tells you is it excludes numbers that are not prime then you end up with a set of numbers that you don't know if they are prime or not and then you run the full primality test on that so you just have to keep iterating on that and it was it was it's it's funny because when he got the picture he was like how did you do that it was super curious too and then we got into the details and again this was he was already 90 i think 92 or something and that curiosity was still there um so you could really see that in in some of these scientists so could we talk about vermont's library yeah absolutely what is it what's the main goal what's the dream it is a platform for annotating papers in its essence right and so academic papers can be one of the densest forms of content out there and generally pretty hard to understand at times and the idea is that you can make them more accessible and easier to understand by adding these rich annotations to the site right and so we can just imagine a pdf view on your browser and then you have annotations on each side and then when you click on them a sidebar expands and then you have annotations that support latex and markdown and so the idea is that you can say explain a tougher part of a paper where there's a step that is not completely obvious or you can add more context to it and then over time papers can become easier and easier to understand and can evolve in a way but it really came from myself luige and two other friends we've been we've had this this long-running habit of kind of running a journal club amongst us we come from different backgrounds right i studied cs we studied physics and so we read papers and present them to each other and uh and then we tried to bring some of that online and that's that's that's when we decided to to to build fermat's library um then over time it kind of grew into into something uh with with a broader goal uh and really what we're trying to do is trying to help uh move science in the in the the right direction that's really the ultimate goal and and where we want to take it now so there's a lot to be said so first of all for people who haven't seen it the interface is exceptionally well done that's like execution is really important here absolutely the other things just to mention for a large number of people apparently which is new to me don't know what latex is so it's spelled like latex so be careful googling it if you haven't before uh it's uh uh sorry i don't even know the correct terminology type setting it's a typesetting language where it's you're basically program writing a program that then generates something that looks from a typography perspective beautiful absolutely and uh so a lot of academics use it to write papers i i think there's like a bunch of communities that use it to write papers i would say it's mathematics physics computer science yeah that's yeah that's the because i'm collaborating currently on a paper with uh two neuroscientists from stanford and they don't know what so i'm using uh microsoft word and uh mendeley and like all of those kinds of things and it's and i'm being very zen like about about the whole process but it's fascinating it's a little heartbreaking actually because uh it actually it's it's funny to say but uh and we'll talk about open science actually the bigger mission behind for mars libraries like really opening up the world of science to everybody is these silly two facts of like one community uses latex and another uses word is actually a barrier between them that's like it's like boring and practical in a sense but it makes it very difficult to collaborate just on that like i think there if there are some people that should have received like a nobel prize that but we'll never get it and i think one of those is like donald knuth because of tech and latex and then because it had a huge impact in terms of like just making it easier for uh researchers to put their content out there like making it uniform as much as possible oh you mean like a nobel peace prize well maybe maybe a couple of peace prizes maybe a nobel peace prize yeah i i think so i mean he at a very young age got the touring award for his work in algorithms and so on so yeah like an incredible yeah like when i i think it's in it might be even the 60s but i think it's the 70s that so when he was really young and then he went on to do like incredible work with his book and uh yeah with tech that people don't know and and going back just one on the reason why we we ended up because i think this is interesting the reason why we ended up using the name for mars library this was because of uh vermont's last theorem and from us livestream is actually a funny story like so pierre de fermat he was like a lawyer and he wrote like on a book that he had a solution to fermat's last theorem which um but that didn't fit the margin of that book and so fermat's lie stream basically states that there's no solution if you have uh integers a b and c there's no solution to a to the power of n plus b to the power of n equals to c to the power of n if n is bigger than two so there's there's there's no solutions and he said that and that problem remained open for almost 300 years i believe and a lot of the most famous mathematicians tried to tackle that problem no one was able to figure that that out until andrea wiles uh i think was in in the 90s was able to publish the solution which was i i believe almost 300 pages long and so it's kind of an anecdote that you know there's a lot of of knowledge and insights that can be trapped in the margins then you and there's a lot of potential energy that you can release if you actually um spend some time trying to digest that and that was the the the origin story for for the name yes you can share the contents of the margins with the world exactly that could inspire a solution or a communication that then leads to a solution but and and if you think about papers like papers are as as jean was saying probably one of the densest pieces of text that any human can read and you have these researchers like some of the brightest minds in in these fields working on like new discoveries and publishing these work on journals that are imposing them restrictions in terms of the number of pages that they can have to explain a new scientific breakthrough so at the end of the day papers are not optimized for clarity and for a proper explanation of of that content because there are so many restrictions so there's as i mentioned there's a lot of potential energy that can be freed if you actually try to digest a lot of the contents of papers can you explain some of the other things so margins librarian journal club so journal club is what a lot of people know us for uh where we every week we release an annotated paper and in all sorts of different fields with physics cs math margins is kind of the same software that we use to to run the journal club and to host the annotations but we've made that available for free to anybody that wants to use it and so folks use it at universities and and for running journal clubs and and so we just made that freely available and then librarian is a browser extension that we developed that is sort of an overlay on top of archive so it's about bringing some of the same functionality around comments plus adding some extra niceties to to archive like being able to very easily extract the references of a paper that you're looking at or being able to extract the bibtex in order to cite that paper yourself so it's an overlay on top of archive the idea is that you can have that commenting interface without having to leave archive it's kind of incredible i didn't know about it and once i've learned of it it's like holy shit why isn't it more popular given how popular archive is like everybody should be using it archive sucks or uh let me rephrase that it's limited yeah in terms of what's interesting archive is a pretty incredible project right and it is in in a way it's it you know it the growth has been completely linear over time if you look at like number of papers published on archive like you know it's just been it's pretty much a straight line for the past 20 years especially for you know like if you're coming from a startup background and then you were trying to do archive you'd probably try like all sorts of growth acts and like try to to then maybe like have paid features and things like that and that would kind of maybe ruin it and so there's there's a subtle balance there yeah and i don't know what what aspects you can change about it and yeah for some tools in science it just takes time for them to to grow archive is just turned 30 i believe yeah and for for people that don't know archive is these kind of online repository where people put preprints which are versions of the papers before they actually make it to journals a-r-x-i-v exactly for people who don't know and it's actually a really vibrant place to publish your papers in in the aforementioned uh communities of mathematics exactly in computer science it started with mathematics and physics and then over the the last 30 years it evolved and now actually computer computer science now it's it's a more popular category than than physics and math on archive and there's also which i don't know very much about like a biology medical version of that bio archive yeah by archive um it's recent it's um it's interesting because if you look at like these um platforms for preprints they are they actually play a super important role because if you look at a category like math for some papers in math it might take close to three years after you click upload paper on the journal website and the paper gets published on the website of the journal so this is literally the longest upload period on the internet um and during those three years like it's it's you know their content is just you know locked and so this that's why it's so important for people to have websites like archive so that you can share that before it goes to the journal with the rest of the world there was actually on archive that uh perumann published the the three pipers that led to the proof of the poincare conject conjecture and then you have other fields like machine learning for instance where the the field is evolving at such a high rate that people don't even wait before the papers go to journals before they start working on top of those papers so they publish them on archive then other people see them they start working on that and archive did a really good job at like building that core platform to host papers but i i think there's a really really big opportunity in building more features on top of that platform apart from just hosting paper so collaboration annotations and like having other things apart from from papers like code um and and other things because uh in the field like machine learning there's a really big you know as i mentioned people start working on on top of preprints and they are assuming that that that preprint is correct but you really need a way for instance to maybe it's not peer review but distinguish what is good work from bad work on archive how do you do that so like a commenting interface like librarian it's useful for that so that you can distinguish that um at in the field that is growing so fast as machine learning and um and then you have platforms that focus for instance on just biology bioarchive is a good example um bioarchive is also super interesting because there there's actually an interesting experiment that was run in the 60s so in the 60s the nih um supported this pro this this experiment called the information exchange group which at the time was a way for researchers to share biology preprints via mail or using libraries and that project in the 1960s got cancelled six years after it started and it was due to intense pressure from the journals to kill that project because they they were fearing a competition from from the uh for in for the journal industry creek uh was also uh was one of the famous scientists that opposed to to the uh information exchange group and it's interesting because right now if you analyze the number of biology papers that appear first as preprints it's only two percent of the papers and it this was almost 50 almost 50 years after that first experiment so you can see like that pressure from the journals to cancel that uh initial version of a pre-print repo had a tremendous impact on on on the number of papers that are showing up in biology as preprints so it delayed a lot that that revolution and um but now platforms like bioarchive are doing that work but there's still a lot of room for growth there and i think it's super important because those are the papers that are open that everyone can read okay so but if we just look at the entire process of science as a big system can we just talk about how it can be revolutionized so you have an idea uh depending on the field you want to make that idea concrete you want to run a few experiments in computer science there might be some code there'd be a data set for you know some of the more sort of biology psychology you might be collecting the data set that's called you know a study right so that's part of that that's part of the methodology and so you are putting all that into a paper form and then you have some results and then you you submit that to a place for review through the peer review process and there's a process where how would you summarize the peer review process but it's it's really just like a handful of people look over your paper and comment and based on that decide whether your paper is good or not so there's a whole broken nature to it at the same time i love the peer review process when i buy stuff on amazon like uh for like uh the commenting system whatever that is so okay so there's a bunch of possibilities for revolutions there and then there's the other side which is the collaborative aspect of the science which is people annotating people commenting sort of the low effort collaboration which is a comment sometimes as you've talked about a comment can change everything but you know or a higher effort collaboration like more like maybe annotations or even like contributing to the paper you can think of like a collaborative updating of the paper over time so there's all these possibilities for doing things better than they've been done can we talk about some ideas in this space some ideas that you're working on some ideas that uh you're not yet working on but should be revolutionized because it does seem that archive and like open review for example are like the craigslist of science like like yeah okay i'm very grateful that we have it but it just feels like it's like 10 to 20 years like it doesn't feel like that's a feature the simplicity of it is a feature it feels like it's a it's a bug [Music] but then again the the pushback there is uh wikipedia has the same kind of simplicity to it and it seems to work exceptionally well in the crowdsourcing aspect of it i'm sorry this there's a bunch of stuff going on on the table let's just pick random things that we can talk about wikipedia you know for me it's the cosmological constant of the internet it's like i think we are lucky to live in the parallel universe where wikipedia exists yes because if if someone had pitched me wikipedia like a publicly edited encyclopedia like a couple of years ago like it would be i don't know how many people would have said that that would have survived yeah i mean it makes almost no sense it's like having a google doc that everybody on the internet can edit and like that will be like the most reliable source for for knowledge and i don't know how many but hundreds of thousands of topics yeah exactly it's insane it's insane and like you have and then you have users like there's one a single user that edited one third of the articles on wikipedia so you have these really really big power users there are a substantial part of like what makes wikipedia successful and so like no one would have ever imagined that that could happen um and so that that's that's one thing i i completely agree with what you just said i also started to interrupt briefly maybe let's inject that into the discussion of everything else i also believe i've seen that with stack overflow that one individual or a small collection of individuals contribute or revolutionize most of the community like if you create a really powerful system for archive or like open review it made it really easy and compelling and exciting for one person who isn't like a 10x contributor to do their thing that's going to change everything it seems like that was the mechanism that changed everything for wikipedia and that's the mechanism that changed everything for stack overflow is gamifying or making it exciting or just making it fun or pleasant or fulfilling in some way for those people who are insane enough to like answer thousands of questions or write thousands of factoids and like research them and check them all those kinds of things or read thousands of papers yeah no stack overflow is another great example of that and it's just and and those are both to incredibly productive communities that generate a ton of value and and and capture almost none of it right and it's and you know in a way it's almost like counter um it's very counter-intuitive that that that people that these communities would exist and thrive um and and it's really hard to you there aren't that many communities like that so how do we do that for science do you have ideas there like what are the biggest problems that you see you're working on some of them like just on that there are a couple of really interesting experiments that people are running an example would be like the polymath projects so this is a so kind of a social experiment that was uh created by tim gowers fields fields medalist and his idea was to try to prove that is it possible to do mathematics in a massively collaborative collaborative way on the internet so we decided to pick a couple of problems and test that and they found out that it it actually it is possible for a specific types of problems namely problems that you're able to break down in in little pieces and go step by step you might need as as with open source you might need people that are just kind of reorganizing the the house every once in a while and then you know people throw a bunch of ideas and then you know you make some progress then you reorganize you reframe the problem you go step by step but they were actually able to prove that it is possible to to uh collaborate online and and do progress in terms of mathematics um and so i'm i'm confident that there are other avenues that could be explored here can we talk about peer review for example absolutely i i think like in in terms of the peer review i think we it's it's important to look at the bigger picture here of like of what this scientific the scientific publishing ecosystem looks like because for me there there are a lot of things that are wrong about that entire process so if you look at for instance at the what publishing means in like a traditional journal you have uh journals that pay um authors for their articles and then they might pay like reviewers to um review those articles and finally they pay people to um or distributors to distribute the content in in the scientific publishing world you have scientists that are usually backed by government grants they are giving away their work for free in the form of papers and then you have other scientists that are reviewing their work this process is known as the peer review process again for free and then finally we have um government-backed universities and libraries that are buying back all those all that work so that other scientists can we can read so this is for me it's bizarre you have the government that is funding the research is paying the salaries of the scientists it's paying the salaries of the reviewers and it's buying back all that uh the product of their work again um and i think the problem with this system and it's what it's why it's so difficult to to break this suboptimal equilibrium is because of of the way academia works right now and the way you can progress in in your academic life and and so in a lot of fields the the competition in academia is is really insane so you have hundreds of phd students there are um trying to get to a professor position and and it's hyper competitive and the only way for you to get there is if you publish papers ideally in journals with a high impact factor in computer science it's all it's often conferences are also very prestigious or actually more prestigious than journals now so interesting so that's the one discipline where i mean that has to do with the thing we've discussed uh in terms of the how quickly the field turns around but like uh in eurips cvpr those conferences are more prestigious or at the very least as prestigious as the journal but doesn't matter the process is what it is and and and so with the the so for people that don't know how the impact factor of a journal is basically the average number of citations that a paper would get if it gets published on that journal but so um you can really think that the problem with the the impact factor is that it's a way to turn papers into accounting units and and and let me unpack this because it's the impact factor is almost like a nobility title so because papers are born with impact even before anyone reads them so the researchers they don't have the incentive to care about if this paper is going to ever a long-term impact on on on the world what they care their goal their end goal is the paper to get published yes so that they get that value up front and so for me that that is one of the problems of of that and that really creates a tyranny of of metrics because at the end of the day if you are a dean what you want to hire is like people researchers that publish papers on journals with high impact factors because that will increase the ranking of your university and will allow you to charge more for tuition so on and so forth and um and and that that especially when you are in super competitive areas you know that people will try to gamify that system and and misconduct starts showing up um there's a a really interesting book on this topic called gaming the metrics it's a book by a researcher called mario biagioli it goes a lot into like how these the impact factor and metrics affect science negatively and it's interesting to think especially in terms of citations if you look at the early work of like looking at citations there was a lot of work that was done by a guy called eugene garfield and this guy the early work in terms of citation they wanted to use they wanted to use citations as from a descriptive point of view so what they wanted to to create was a map and and that map would create a visual representation of of influence so citations would be links between papers and the ideally what they would show they would represent is that you read someone else's paper and it had an impact on your research they weren't supposed to be counted i think this inspired like larry and sergey's exactly worked right for google exactly i think they even mentioned that but what happens is like as you start counting citations you create a market and and the same way like and this was the the work of eugene garfield was a big inspiration for larry and sergey for the pagerank algorithm that um you know led to the creation of google and they even recognize that and and if you think about it's like the same way there's a gigantic market for search engine optimization uh seo where people try to optimize you know the the page rank and how i the uh of a web page will rank on google the same will happen for papers people will try to optimize like their site their the impact factors and the citations that they get and that um creates a really big problem and if it's super interesting to actually analyze them if you look at the distribution of the high impact the impact factors of journals you have like nature with nature i believe it's like in the low 40s and then you have i believe science is high 30s and then you have a really goo a good set of good journals that will fall between 10 and 30 and then you have a gigantic tale of of journals that have impact factor below two and you can really see two economies here you see the the you know the universities that are maybe less prestigious less known that where the faculty are pressured to just publish papers regardless of the journal what i want to do is increase the ranking of my university and so they end up publishing as many papers as as they they can in like journals with low impact factor and unfortunately this is represents a lot of of the global south and then you have the luxury good economy so for instance for and there are also problems here in the luxury good economy so if you look at the journal like nature so with impact factor of like in the low 40s there's no way that you're going to be able to sustain that level of impact factor by just grabbing the attention of scientists what what i mean by that is like for for the journals the articles that get published in nature they need to be new york times great so they need to make it to the you know to the to the big media they need to be captured by the big media and because that's the only way for you to capture enough attention to sustain that level of citations yes and that of course creates problems because people then will try to again gamify the system and have like titles or abstracts or that are bigger claim make claims that are bigger than what is actually can be um you know sustained by by the data or the the content of the paper and you'll have clickbait titles or clickbait abstracts and again this is all a consequence of metrics and uh scientometrics and and this is a very dangerous cycle that i think it's very hard to break but it's happening in academia in a lot of fields right now is it fundamentally the existence of metrics or the metrics just need to be significantly improved because uh like i said the metrics used for amazon for purchasing i don't know computer parts it's pretty damn good in terms of selecting which are the good ones which are not in that same way if if we had an amazon type of review system in the space of ideas in the space of science it feels like that those metrics would be a little bit better sort of when it's um when it's significantly more open to the crowd source nature of the internet of the of the scientific internet meaning as opposed to like my biggest problem with peer review has always been that it's like five six seven people usually even less and it's often nobody's incentivized to do a good job in the whole process meaning it's anonymous in a way that doesn't incentivize like doesn't gamify or incentivize great work and also it doesn't necessarily have to be anonymous like there has to be um the entire system is um doesn't encourage actual sort of rigorous review for example like open review does kind of incentivize that kind of process of collaborative review but it's also imperfect it just feels like the thing that amazon has which is like thousands of people contributing their reviews to a product it feels like that could be applied to science where the same kind of thing you're doing with vermont's library but doing at a scale that's much larger it feels like that should be possible given the number of grad students given the number of um general public that get like for example i personally as a person who got an education in mathematics and computer science like uh i can i can be a quote-unquote like reviewer on a lot bigger set of things than than is my exact uh expertise if i'm one of thousands of reviewers if i'm the only reviewer or one of five then i'd better be like an expert in the thing but if if i uh and i've learned this with covet which is like you can just use your basic skills as a data analyst as a and to contribute to the review process and a particular little aspect of a paper and be able to comment be able to sort of uh draw in some references that challenge the ideas presented or to enrich the ideas that are presented or you know and it just feels like crowdsourcing the review process would be able to allow you to have metrics in terms of how good a paper is that are much better representative of its actual impact in the world of its actual value to the world as opposed to some kind of arbitrary gamified version of its impact i agree with that i i think we there's definitely the possibility at least for more resilient a more resilient system than what we have today and that's i think that's kind of what you're describing alex and and i mean to an extent we we kind of have like a little bit of a heisenberg uncertainty principle when you pick a metric as soon as you do it then maybe it works as a good heuristic for for a short amount of time but soon enough people would start gamifying and yeah but but then you can definitely have metrics that are more resilient to gamification and they'll work as a better heuristic to to try to push you in the in the best direction but i guess the underlying problem you're saying is uh there's a shortage of positions in academia that's a big problem for me yeah and and that and so they're going to be constantly gamifying the metrics it's a bit of a zero-sum it's very competitive it's what it's a very competitive field and and that's what usually happens in very competitive fields yeah yeah but i think some of like the peer review problems like scale helps i think and and it's interesting to look at like what you're mentioning breaking it down maybe in my smaller parts and having more people jumping in um but th this is definitely a problem and and the peer review problem as i mentioned is is correlated with the problem of like academic career progression and it's all intertwined and it's what that's why i think it's so hard to to break it um there are like a couple of really interesting things that are being done right now there are a couple of for instance journals that are overlaid journals on top of platforms like archive and bioarchive that want to remove like the more traditional journals from the equation so essentially a journal is just a collection of links to papers and and um and what they are trying to do is like removing that middleman and trying to to make the review process a little bit more transparent um and and and not charging universities like uh there's there's a couple of there are a couple of more famous um ones there's one discrete analysis in mathematics there's one uh called the quantum journal which we are actually working with them we have a partnership with them for the purpose that get published in quantum journal they also get the annotations on formats um and they are doing pretty well they've been able to grow substantially the problem there is getting to critical mass so it's again convincing the researchers and especially the young researchers that need need that impact factor need those publications to have citations to not publish on the traditional journal and go on an open journal and and publish their work there there i think there are a couple of really high-profile scientists of people like team gowers that are trying to incentivize like famous scientists that already have tenure and that don't need that to publish that to increase the reputation of those journals so that other maybe younger scientists can start publishing on on those as well and so they can try to break that vicious cycle of of um the more traditional journals i mean another possible way to break this cycle is to like raise public awareness and just by force like ban paid journals like what exactly are they contributing to the world like basically making it illegal to uh forget the fact that it's mostly federally funded so that's that's a super ugly picture too but like why should knowledge be so expensive like where everyone is working for the public good and then there's these gatekeepers that you know most people can't read most papers without having to pay money and that's that doesn't make any sense that's like that that should be illegal i mean that's what you're saying is exactly right i mean for instance right i i went to school here in the us we studied in europe and you would sit like you'd ask me all the time to download papers and send it to him because he just couldn't get it and like papers that he needed for his research and so but he's a student like he's yeah he's a grad student he was a grad student but that you know i'm even referring to just regular people oh yeah okay that too yeah and i i think uh during 2020 because of covet a lot of journals put down the walls for certain kind of coronavirus or papers but like that just gave me an indication that like this should be done for everything it's it's absurd like people should be outraged that there's these gates because so the moment you dissolve the journals then there will be an opportunity for startups to uh build stuff on top of archive it'd be an opportunity for like vermont's library to step up to scale up to something much even larger i mean that was the original dream of uh google which i always admired which is make the world's information accessible actually it's interesting that google hasn't maybe you guys can correct me but they uh put together google scholar which is incredible but they and they've did the scanning of books but they've haven't really tried to make science accessible in the in the in the following way like besides doing google scholar they haven't like delved into the papers right mm-hmm which is especially curious given what louise was saying right that it's kind of in their genesis there's this you know research that was very connected with our papers reference each other and like building a network out of that interesting enough like google but i think there was a there was not intent google plus was like the google social network that got canceled was used by a lot of researchers yes it was uh whether i think was just a you know side kind of a side effect but then a lot of people ended up migrating to twitter but it was not on purpose but yeah i agree with you like they haven't um gone past the google scholar and well you know what that said google's call is incredible people who are not familiar it's one of the best aggregation of all the scientific work that's out there and especially the network that connects to all of them what sites what and also trying to aggregate all the versions of the papers that are available there and trying to merge them in a way that uh one particular work even though it's available in a bunch of places counts as you know like a central hub of what that work is across the multiple versions but that almost seems like a fun project of a couple of engineers within within google as opposed to a serious effort to make the world's science accessible but but going back to just the the journals when you're talking about that lex i i believe that in that front i think we might be past the event horizon so i think the the the model the business model for the journals you know doesn't make sense they are a middle layer that is not adding a lot of value and you see a lot of motions whereas like in europe a lot of the the papers that are get are funded by the european union they will have to be um uh open to the public and i think there's a lot of bill gates to like the the what the gates foundation funds like they they demand that it then it that it's uh accessible to everybody oh interesting so i think it's it's the question of time before that that wall kind of falls and and that is going to open a lot of possibilities um because you know imagine if if you had like the layer of like that gigantic layer of papers all available online um you know that unlocks a lot of potential as a platform for people to build things on top of that but i think it's what you're saying it is weird like you can literally go and listen to any song that was ever made on your phone right you open spotify and you might not even pay for it you might be on the free version and you can listen to any song that has ever made pretty much but there's like you you don't have access to a huge percentage of academic papers which is just like this fundamental knowledge that we're all funding but you as an individual don't have access to it and and somehow you know like the problem for music got solved uh but for papers it's still like it's just not yet it could be ad supported all those kinds of things and that hopefully that would change the way we do science that's the most exciting thing for me is uh especially once i started like making videos in this silly podcast thing i started to realize like that if you want to do science one of the most effective ways is to do uh like couple the paper with a set of youtube videos like explaining it like yeah that also seems like there's a lot of room for disruption there what is the paper 2.0 gonna look like i think like latex and the pdf seems like if you it's interesting if you look at the first paper that got published in nature and if you look at the paper that got published in nature today look at the two side by side they are fundamentally the same and even though like the paper that gets published today you know you get even even code like right now people put like code like on on a pdf like and there are so many things that are related to papers today you know you use you have data you have code um you might need videos to to better explain the concepts so it's it i i think for me it's natural that there's going to be also an evolution there that papers are not going to be just the static pdfs or latex there's going to be a next uh next interface so in academia a lot of things that are judged your judge by is often quantity not quality i i wonder if there's a opportunity to have like i tend to judge people by the best work they've ever done as opposed to i wonder if there's a possibility for that to encourage sort of um focusing on the quality and not necessarily in paper form but maybe a subset of a paper subset of idea almost even a blog post or an experiment like why does it have to be published in a journal yeah to be legitimate and and it's just interesting that he mentioned that i also think like yeah it's why why why is that the only format why can't a blog post or uh we were even experimenting experimenting with these a few months ago or can you actually like publish something or um like a new scientific breakthrough or um or something that you've discovered in the form of like a set of tweets yeah the twitter thread why can't that be possible and um we were expanding experimenting with that idea uh we even um yeah we ran a couple of of like some people submitted a couple of those like i think the limit was three or four tweets yeah uh maybe it's a new way to look at a you know a proof or something but uh i think it just serves to show that there should be other ways to publish like scientific discoveries that don't fit the paper format well but so even with the twitter thread it would be it would be nice to have some mechanism of formalizing it and making it stat making it into an nft like a concrete thing that you can reference is a link that's unique because uh i mean everything we've been saying all of that while being true it's also true that the constraints and the formalism of a paper works well it like forces you constraints forces you to narrow down your thing and and uh literally put it on paper but you know i agree uh make concrete and that's why i mean it's not broken it's just could be better and that's the main idea i think there's something about writing whether it's a blog post or twitter thread or a paper that's really nice to to concretize a particular little idea that they can then be referenced by other ideas then it can be built on top of with other ideas so uh let me ask you've read quite a few papers you've uh annotated quite a few papers let's talk about the process itself how do you advise people read papers or maybe you want to broaden it beyond just papers but just read concrete pieces of information to understand the insights that lay within i would say for paper specifically i would i would bring back kind of what louise was talking about it is that it's important to keep in mind that papers are not optimized for ease of understanding and so right there's all sorts of restrictions in size and format and and language that they can use and so it's important to keep that in mind and so that if you're struggling to read a paper doesn't that might not mean that the underlying material is actually that hard and so so that's definitely something that that especially for us that we we read papers and most of the times the lead papers are completely outside of our of our comfort zone i guess and and to be completely new areas to us um so i always try to to keep that in mind so there's usually a certain kind of structure like abstract introductions methodology uh depending on the community and so on is there something about the process of like how to read it whether you want to skim it to try to find the parts that are easy to understand or not uh reading it multiple times is there any kind of hacks that you can comment on i remember like feynman had this this kind of hack when it was reading papers where he would basically um would i think i believe he would read the conclusion of the paper and we would try to just um see if he would be able to figure out how to get to the conclusion in like a couple of minutes by himself and um and he would read a lot of papers that way and i think fermi also did that almost and fermi was known for doing a lot of back of the envelope calculation so he was a master at doing that um in terms of like especially when when reading a paper i think a lot of times people might feel discouraged about the first time you read it you know it's very hard to grasp or you don't understand a huge fraction of the paper and i think it's having read a lot of papers in my life i think i've in peace with like the fact that you might spend hours where you're just reading a paper and jumping from paper to paper reading citations and um like your level of understanding of sometimes of the paper is very close to zero percent and all of a sudden you know everything kind of makes sense and and in your mind and then you know you have this quantum jump where all of a sudden you you you understanding the big picture of the paper and uh i i and and this is an exercise that i have to when reading papers and especially like more complex papers like okay you don't understand because you're just going through the process and just keep going and like and it might feel super chaotic especially if you are jumping from reference to reference you know you might end up with like 20 tabs open and you're reading a ton of other papers but it's just trusting that process that at the end like you'll find light and i think for me that's a good framework when reading a paper it's hard because you know you might end up spending a lot of time and you it looks like you're lost but uh but that's the process to actually um you know understand what they're talking about in the paper yeah i think that process i enjoy i've found a lot of value in the process especially for things outside my field of reading a lot of related work sections and kind of go going down that path of getting a big context of the field because what's especially when they're well written there's opinions injected into the related work like what work is important what is not and if you read multiple related work sections that cite or don't cite each other like the papers you get a sense of where the field where the tensions of the field are where this where the field is striving and that helps you put into context like whether the work is radical whether it's overselling it itself whether it's underselling itself all those things uh and on adding on top of that i find that often the related work section is the most kind of accessible and readable part of a paper because it's kind of uh it's brief to the point it's trying like summarizing it's almost like a wikipedia style article the introduction is supposed to be a compelling story or whatever but it's often like overselling there's like an agenda in the introduction the related work usually has the least amount of agenda except for the few like elements where you're trying to uh talk shit about previous work where you're trying to sell that you're doing much better but other than that when you're just painting where the where the field came from or where the field stands that's really valuable and also again just to agree with finding the conclusion it's like i get a lot of value from the breadth first search kind of read the conclusion then read the related work and then go through the references in the related work read the conclusion read the related work and just go down the tree until you like hit dead ends or run out of coffee and then through that process you go back up the tree and now you can see the results in their proper in their proper context unless of course the paper is truly revolutionary which even that process will help you understand that is in fact truly revolutionary you've also um you talked about just following your twitter thread in a depth first search you talked about that you read uh the book on grisha pearlman go to brahman and then you would you had a really nice twitter thread on it and you were taking notes throughout so at a high level is there suggestions you can give on how to take good notes whether it's we're talking about annotations or just for yourself to try to put on paper ideas as you progress through the work in order to then like understand the work better for me i always try not to underestimate how much you can forget uh within six months right after you've read something i thought you're gonna say five minutes but yeah six months is good yeah or or even shorter and so that's something i always try to keep in mind and uh and it's and it's often i mean every once in a while i'll read back a paper that i annotated on vermont and it's and uh and i'll read through my own annotations and it's uh and i've completely forgotten what i had written and but it also it also it's interesting because in a way after you just understood something you're kind of the best possible teacher that can teach your future self uh yeah you know after you've forgotten it uh you can you're kind of your own best possible teacher at that moment and so it's it can be great to try to capture that it's it's brilliant it just made me kind of realize it's really nice to to put yourself in the position of teaching an older version of yourself exactly that returns to this paper almost like thinking it literally that's underexplored but it's it's super powerful because you were the person that you can like if you if you look at the scale from like one not knowing anything about the topic and ten like you are the one that progressed from one to ten and you know which steps you struggled with so you're the really the best person to help yourself make that transition from one to ten and um a lot of the times like and we don't i really believe that the framework there we have to like just expose ourselves to like be talking to like us when we were an expert when we were taking that class and we knew everything about quantum mechanics and then six months later you don't remember half of the things how could we make it easier for a like to have those conversations between you and your past self past expert self um i i think there there might be you know it's an underexplored idea i think notes on paper are probably not the best way i'm not sure if it's a combination of like video audio where it's like you have a guided framework that you follow to extract information from yourself so that you can later kind of revisit to make it easier to to remember but that's i think it's an interesting idea worth worth exploring that not i've i haven't seen a lot of people kind of trying to uh distill that problem you know i'm creating the kind of tools i find if i record it it sounds weird but i'll take notes but if i record audio like um like little clips of thoughts like rants that's really effective at capturing something that notes can't because when i replay them for some reason it loads my brain back into where i was when i was reading that in a way that notes don't like when i read notes i'll often be like what what what was i what was i thinking there but when i listened to the audio yeah it brings you right back to that place so there might and maybe with video with visual that might be even more powerful i think so yeah and and i think just the process of you know verbalizing it that alone kind of makes you have to structure your thought and and put it in a way that somebody else could come and understand it and and just the process of that is useful to to organize your thoughts and and and um yeah just just that alone does the firmware's library journal club have a like a video component or no we no not natively we sometimes will include uh videos but it's always embedded do people like build videos on top of it to explain the paper because you're doing all the hard work of understanding deeply the paper not we haven't seen that happening too much but uh we were we were actually playing around with the idea of creating some sort of podcast version where we try to distill the paper on an audio format that not maybe you could have access might be trickier but you there's definitely people that could be interested in the paper in that topic but are not willing to read it but they might listen to a 30 minute episode on that paper yes you could reach more people and and you might even bring the authors to the conversation but it's tricky especially for like more technical papers we've we've thought about that doing that but we haven't uh like converge so if you have any uh well i'm gonna take that as a a small project to take one of you one of the females almost like half advertisement and half as a challenge for myself to take take one of the annotated papers and like use it as a basis for creating a quick video i i i've seen like um hopefully i'm saying the name correctly but machine learning street talk i think that's the name of the show the that i recommend highly that's the right thing but uh they they do exactly that which is multiple hour breakdown of a paper with video component sometimes with authors um people love it it's very effective there's there's also i've seen i haven't seen the entire in its entirety but i've seen like the the founder of comma dot ai george yeah i've seen him like just taking a paper and then you know distilling the paper and coding it coding it sometimes during 10 hours yeah and um he was able to you know get a lot of people interested in in that and viewing him so i'm a huge fan of that like uh george is a personality i think a lot of people like listen to this podcast for the same reason it's not necessarily the contents it's they they they like to listen to like a a silly russian who has a childlike brain and mumbles and all those like struggle with ideas right and george is a madman who people just enjoy like how is he going to struggle in implementing this particular paper how is he going to struggle with this idea it's fun to watch and that actually pulls you in the personality is important there true but there's lots there's you know i agree with you but they're also it's visible like it's there's an extraordinary ability that is there like is talented and you need to have there's a craft and this guy definitely has talent and he's doing something that is not easy and i think that also draws the attention of people oh yeah and and like the other day we were actually we ran into this youtube channel of this guy that was restoring art right um yeah and and um it was basically just a video of him like his the production is really uh like really well done and it's just him taking really old um pieces of of art like and then paintings and then restoring them but he's really good at that and he describes that process and that draws attention uh draws the attention of people regardless of your craft be it like annotating your paper or like responsibilities excellence yeah like george is incredibly good at programming like quick like you know those uh competitive programmers like top motor and all this kind of stuff he has the same kind of element where the brain just jumps around really quickly and that's uh yeah just like yeah it's motivating but but and you're right in in watching people who are good at what they do it's motivating even if the thing you're trying to do is not what they're doing it's just like contagious when they're really good at it and the same kind of analysis with the paper i think so not just like the final result but the process yeah struggling with it that's really interesting yeah i think i mean i think twitch proved that like you know that there's really a market for for that for watching people do things that they're really good at and and you'll just watch it you will enjoy that that that might even uh spike your interest in that specific topic and yeah and people people will enjoy watching sometimes hours on end of yeah great craftsmen do you mind if we talk about some of the papers do any papers come to mind that have been annotated on the vermont's library the papers that we annotated can be about completely random topics but that's part of what we enjoy as well it forces you to explore these topics that otherwise maybe you'd never run into uh and so so the ones that come to mind that to me are fairly random but one that i i really enjoyed learning more about is um a paper uh written by a mathematician actually tom apostol and uh about a a tunnel in uh greek island off the coast of turkey i think it's already random so this uh okay so what's interesting about this tunnel so this tunnel um was built in the sixth century bc and um and it was built in this in the island of samos uh which is as i said off the coast of turkey and um right they had the city on one side and the other mountain and then they had a bunch of springs on the other side and they they wanted to bring water into the city um did building an aqueduct would be pretty hard because of the way the mountain was shaped and it would also you know if they if they were under a siege like they could just um easily destroy that aqueduct and then the water wouldn't have any water supply the the city wouldn't have any water supply and so they decided to build a tunnel and they decided to try to do it quickly um and so the they started digging uh from both ends at the same time through the mountain right and so like when you start thinking about this it's it's a fairly difficult problem and this is like 6th century bc so you had very limited access to you know the mathematical tools that you had at the time were very limited and so what this paper is about is about the story of how they built it and about the fact that for about 2000 years kind of the accepted the accepted explanation of how they built it was actually wrong and so this tunnel has been famous for a while there are a number of historians that talked about it since ancient egypt and um and the method that they described uh for for building it um is is uh was just wrong and and so these these researchers went there and and were able to figure figure that out and so basically kind of the way that they thought they had built it was basically if you can imagine looking at the mountain from the top and you have the mountain and then you have both entrances um and so what they what they thought and what this is what the ancient historians described is that they effectively tried to draw a right angle a right angle triangle um with the two entrances at each end of the hypotenuse and the way they did is like they would go around the mountain and kind of walk in a grid fashion and then you can you can figure out uh the two sides of the triangle and then after you have that triangle you can effectively draw two smaller triangles at each entrance that are proportional to that big triangle and then you kind of have arrows pointing in each way and then you can you know at least that these that you have a line going through the the mountain that connects both entrances the issue with that is like once you once you go to this mountain and you start thinking of doing this you realize that especially given that the tools that they had at the time that your error margin would be too small you wouldn't be able to do it uh you you you the just the fact of of trying to to build this triangle in that fashion the error would accumulate and you would end up missing you'd start building these tunnels and they would miss each other so the task ultimately is to figure out like really perfectly as cl as close as possible the direction you should be digging first of all that it's possible to have a straight line through and then what that the direction would be and then you're trying to infer that by constructing a right triangle by doing i i'm not exactly sure about how to do that rigorously like by tracing the mountain by walking along the mountain how to you said grids yeah you kind of walk as if you were in a in a grid and so you just walk in right angles i so right but then you have to walk really precisely then exactly you have to use tools to measure this and then the terrain is probably yeah very messed up so this makes more sense in 2d and 3d gets even weirder so okay gotcha but so this method was described by like an ancient egyptian historian i think hero of alexandria and um and then for about like yeah for about 2000 years that's that's how like that's how we thought that they had built this this tunnel um and then in the end then these researchers went there and and found out that actually they they must have had to to use other methods and and then in this paper they describe these these other methods and of course they can't know for sure but there's uh they presented a bunch of plausible alternatives the one that for me was is the most plausible is that what they probably must have done is to use something that is similar to an iron sight on a rifle the way you can line up uh your rifle with the target off in the distance by by having an iron sight um and uh and they they they must have done something similar to that effectively with tree with three sticks and that way they were able to line up sticks along the side of the mountain that were all on the same height and so that then you could get to the other side and you could cut and then you could draw that line so this for me is the most plausible way that they might have done that and they but then they they they describe this in detail and other possible approaches in this paper so this is a mathematician doing this yeah this is a mathematician that did this um which i suppose is the right mindset instead of skills required to solve an ancient problem right yeah yeah there's mathematicians and engineers a lot of things because they didn't have uh computers or drones or lidar back then or whatever technology you would use modern day for civil engineering yeah and another fascinating thing is that like you know after effectively after the the downfall of the roman civilization people didn't build tunnels for about a thousand years we go a thousand years without tunnels and then like only in like in late middle ages that we start doing them again but uh but here is the tunnel like 6th century bc like incredibly limited mathematics and they and they build it in this way um and and and for and it was a mystery for for a long time exactly how they did it and then these mathematicians went there and and uh and and basically with no archaeology kind of background we're able to figure it out how do annotations for this paper look like what is it uh what's a successful annotation for paper like this yes so sometimes you're uh for this paper um sometimes adding some more context uh on on a specific um part like sometimes they they mentioned for instance um these instruments that were common in ancient greece and an ancient rome for for building things and uh and and so in some of those annotations i described these instruments in more detail and how they worked because sometimes it can be hard to to visualize these um then this paper um i forget exactly when when this was published uh i believe maybe maybe the 70s um but then there was further research into this tunnel and more interesting other interesting aspects about it i add those to that paper as well there's historical context that i also go into uh there for instance the fact that as a as i said that effectively after the downfall of the roman empire no tunnels were built like that's something that i that i go that i that i added to the paper as well yeah so so this is so when other people look at the paper how did they usually consume the annotations so they it's like is there a commenting feature is uh i mean like this is a really enriching experience the way you read a paper what what aspects do you do people usually talk about that they value from this so yeah so anybody can just go on there and and either add a new annotation or other a comment to an existing annotation and so you can start a kind of a thread uh within an existing annotation um and that's something that happens relative frequency and then because i was the original author of the initial annotation i get pinged and so often times i'll go back and and and add on to to that thread how did you pick the paper that's i mean first of all this whole process is really exciting i'm gonna especially after this conversation i'm gonna make sure i participate much more actively on papers that i know a lot about and on paper i know nothing about i shouldn't bother when i say the paper i would love to i also i mean i i realized that uh there's a like it's an opportunity for people like me to publicly annotate a paper like like or do an ama around the paper like yeah exactly but yeah but like be um be in the conversation about a paper it's like a place to have a conversation about an idea you could the other way to do it that's much more ad hoc is on twitter right but this is more like formal and you could actually probably integrate the two they have a conversation about the conversation so the twitter is the conversation about a conversation and the main conversation is in the space of annotations there's an interesting effect that we we see sometimes with the annotations on our papers is that a lot of people especially if we the annotations are really well done people sometimes are afraid of adding more annotations because they see that as a kind of a finished work yes and so they they don't want to pollute that or and especially if it's like a silly question this is i don't think that's good i think you know we should as much as possible try to lower the barrier for someone to jump in and ask questions i think it only like most of the times it adds value but it's some feedback that we got from users and and readers um i'm not exactly sure how to to kind of fight that but um well i think i i think if i serve as an inspiration in any way is by asking a lot of dumb questions and saying a bunch of dumb shit all the time and hopefully that inspires the rest of uh other folks to do the same because that's the only way to knowledge i think is to be willing to ask the dumb questions and and there are papers that are like um and we have a lot of papers on formats where it's just one page or really short papers and you we have like the shortest paper ever published in a math journal like with like just a couple of words one of my favorite papers on the platform is actually a paper um written by enrico fermi yeah and the title of the paper is myop's i think it's my observations at trinity so basically fermi was part of the manhattan project so he was in new mexico when um they exploded the first atomic bomb and so he was a couple of miles away from the explosion and he was probably one of the first persons to calculate the energy of the explosion and so the way he did that was he took a piece of paper and he tore down a piece of paper in little pieces and when the bomb exploded the trinity bomb was the name of the bomb like he waited for the blast to arrive at where he was and then he threw those pieces of paper in the air and he calculated the energy based on the displacement of the paper the pieces of paper and then he wrote a report which was classified until like a couple of years ago one page report like calculating the energy of the explosion uh it's so badass and i i we actually went there and kind of unpacked and like yeah i think it just mentions basically the energy and we we actually went and one of the annotations is like explaining how he did that um i wonder how accurate he was it was maybe i think like 20 20 or 25 off uh then there was another person that actually calculated the energy based on uh images after the explosion at the rate uh and the rate that which the the the like the mushroom of the explosion expanded and it's more accurate to calculate the energy based on that um and i think it was like 20 20 off but it's it's really interesting because you know fermi was known for all these being a master at this back of the envelope calculations always like the the fermi problems are well known for for that um and it's super interesting to see like that just one page report and was also actually classified and it's interesting because a couple months ago when the beirut explosion happened there was a video circulating of these a bride that was doing a photo shoot when the explosion in beirut happened and so you can see a video of her with the wedding dress and then the explosion happens and the blast arrives at where she was she was a couple of miles away from the glass and you can see like um the displacement of the dress as well and i actually looked and that video went viral on twitter and i actually looked at that video and based i used the same techniques that fermi used to calculate the energy of the explosion uh based on the displacement of the dress and you could actually see where where she was at the the distance from the explosion because there was a store behind her and you could look the name of the store and and so i calculated that it was the distance and then you can then based on the distance where she was from the the explosion and also on the the displacement of the dress like because you can when the blast happens like you can see the dress going back and then going back to the original position and like by just looking at like how much the the dress moved you can estimate the explo the energy of the explosion i assume you published this on twitter it was just a a twitter thread uh but it it actually like a lot of people share that and it was picked up by a couple of of um news outlets but i i was hoping it would be like a formal title and it would be an archive no no no no maybe you submitted it just the twitter the twitter thread but it was interesting because it was exactly the same method that fermi used is there something else that jumps to mind like what is there something i know like in terms of papers like i know the bitcoin paper is super popular is there something interesting to be said about any of the white papers in the cryptocurrency space yeah the the bitcoin paper was the first paper that we put on for mods and uh why why that why that choice as the first paper this was a while ago and it was one of the papers that i read and then and then kind of explained it to to louisiana or to other friends that do this journal club with us and um i did some research in cryptography uh as an undergrad and so it was a topic that i was interested in um but even for me that i i had that background but reading the bitcoin paper it took me a few weeks to really kind of wrap my head around it it's it's right it's it uses very spartan precise language in a way it's like you feel like you can't take any word out of it without something falling apart and uh and it's all there i think it's a beautiful paper and it's it's it's very well written of course but um you know we wanted to try to make it accessible so that anybody that maybe is an undergrad in computer science could go on there and then and and know that you have all the information in in that page that you're going to need to understand the mechanics of bitcoin and so like i explain you know the basic uh public key cryptography that you need to to know in order to understand it you can explain okay what are the properties of a hash function and how they are useful in this context um explain what a merkle tree is so a bunch of those basic concepts that maybe if you're reading it for a first time and you're an undergrad and you know you don't know those terms you're going to be you know discouraged because maybe okay now i have to go and google around until i understand these before i can make progress in the paper um and and this way it's all there you know so so there's a magic to also to the fact that over time more people went on there and and added further annotations so the idea that the paper gets easier and more accessible over time but that's still you're still looking at the original content the way the the author intended it to be uh but there's just more context and the toughest bits have have more in-depth explanations okay i think like there's a there's so many interesting papers uh there like i remember reading the paper that was written by freeman dyson on the like the the first time that he explained or he came up with the concept of the dyson sphere and he he put that out like it's again it's one page paper um and he what he explained was that eventually if a civilization develops and and grows there's going to be a point where when the resources on the planet are not are not enough for the energy requirements of that civilization so if you want to go the next step is you need to go to the next star and extract energy from that star and the way to do it is you need to build some sort of cap around the star that extracts the energy so he theorized this idea of the the dyson sphere and he went on to kind of analyze how he would build that the stability of that sphere like if something happens if there's like a small oscillation with that fear collapsing to the star or no what what would happen and even went on to uh kind of say that a good way for us to look for signs of intelligent life out there is to look for signals of these dyson spheres and because you know according to the law of second law of thermodynamics like this there's going to be some a lot of infrared radiation that is going to be emitted as a consequence of extracting energy from the star and we should be able to see those signals of like infrared if we look at the sky but all these like from the introduction of the concept like the pro how to build the dyson sphere the problems of like having a dyson sphere how to detect how that could be used as a signal for intelligence like really that's all in the paper all in one like one page paper and it's like it's it's for me it's beautiful it's like where was this published i don't remember it it's fascinating that papers like that could be yeah i mean the guts it takes to put that all together in a paper you know that that kind of challenges our previous discussion that of paper i mean papers can be beautiful you can play with the format right it but there's a lot to unpack there that's like the the that's the the starting point but it's it's it's beautiful that you're able to put that in one page and then people can build on top of that and but the key ideas are there yeah exactly what about have you looked at any of the the big seminal papers throughout the history of science like you look at simple like einstein papers have any of those been annotated yeah yeah no we we have some more seminal papers that that people will have heard about um you know we have the the dna double helix paper on there we have the higgs boson paper um yeah there's papers that that we know that it's they're not going to be finding out about them because of us but it's papers that we think should be more widely read and that folks would benefit from having some annotations there and so we also have a number of those a lot of like discovery papers for fundamental like particles and all that there's we have a lot of those on from us library um yeah we i would like to end we haven't annotated that one but i'd like to on the riemann hypotheses that's a really interesting paper as well um and and but we haven't annotated that one but there's a lot of like more historical landmark papers um on the platform have you done uh point correct conjecture with uh with perlman that's too much that's too much that's too much too much for me but it's uh it's it's interesting that you know and going back to our discussion like the the poincare paper was like published on archive and and it was not on a journal like the three papers and yeah what do you make of that i mean he's such a fascinating human being exactly i mentioned to you offline that i'm going to russia he's somebody i'm really trying to interview yeah well so i definitely will interview him i um and i believe i will i believe i can i just don't know how to i know where you live so here okay my my uh my hope is my conjecture is that if i just show up to the house and look desperate enough uh that uh or threatening now for some combination of both that like the only way to get rid of me is to just get the thing done that's the hope it's actually interesting that you mentioned that because i after i um so a couple of weeks ago i was searching for like stuff about paramount paramount online and ended up on this twitter account of like this guy that claims to be paramount perlman's assistant and he is like he has been posting a bunch of pictures like next to paramount you can see like permanent in in a library and he's like next to him like taking a selfie or like firm and walking on the street and like maybe you could reach out to this assistant then i'll send you i'll send you this twitter account so maybe you're on to something no but but going back to like pheromone is super interesting because the fact that he published the the the proofs on archive is what was also like a way for him to because he really didn't like the scientific publishing industry and the fact that you had to pay to get access to to articles and that was a form of like protest and that's why he published um those papers there i mean i i think paramount is just a fascinating like character and for me it's this kind of ideal of a platonic ideal of what a mathematician should be you know it's it's someone that is you know it just cares about deeply cares about mathematics you know it cares about fair attribution of um disregards money and um and and like the fact that he published like on archive was is a good example of what about the fields metal that he turned down the fields metal what's what's yeah what do you make of that yeah i mean if you look at like the reasons why he rejected the fields medal so after so paramount did a post talk in the us and when he he came back to russia um do you know how good his english is i think it's very fairly good it's pretty good i think it's really good especially given lectures in american union but i haven't been able to listen to anything well certainly not listen but i haven't been able to get anybody because i know a lot of people have been to those lectures i'm not able to get a sense of like yeah but how strong is the accent what are we talking about here is this gonna have to be in russian is it gonna have to be in english it's fascinating but he writes the papers in english so it's true like there's there's but there's so many like such a fascinating character and um there are a couple of examples like him like at i think 28 or 29 he proved like a really famous uh conjecture called the sulk conjecture i believe it was like in a very short four-page proof of that it was a really big breakthrough then he went to princeton to give a lecture on that and after the lecture the the chair of the math department at princeton a guy called peter sarnock went up to the parliament was trying to recruit him trying to offer him a position at princeton and he was and at some point he asked for perlman's resume and fellman responded saying just gave a lecture on like this really tough problem why do you need my resume like i'm not gonna send you like i just proved like my value but uh but going back to the fields metal like when when perlman went to back to russia he he arrived at a time where the the salary of post docs was so much off in regards to inflation that they were not making any money like they people didn't even bother to pick up the checks at the end of the month because it was like ridiculous but thankfully he had some money that he had uh gained while he was doing his post talk so he just concentrated on like the poincar the the prank reconjecture problem which he when he when he took that um it took it after it was reframed by this mathematician called richard hamilton which posed the problem in a way that it turned into this super like math olympiad problem with like perfect boundaries well defined and that was perfect for paramount to attack and so he spent like seven years working on that and then in 2002 he started publishing those papers on archive and people started jumping on that reading those papers and there was like a lot of excitement around that a couple of years later there were two researchers i believe was they were from harvard that but took paramount pearlman's work they sanded some of the edges and they republished that saying that you know based on pearlman's work they were able to figure out the the pronghorn conjecture and then there was um at the time at the in the international um conference of of mathematics in 2000 2006 i believe that's when they were going to give out the fields medal there was a lot of debate of like oh who's who's like we should get the credit for solving this big problem and for apparelmen it like it it felt really sad that people were even considering that he was not the person that solved that and and the claims that those like researchers uh when they published after paramount there were false claims that they were the ones they just sanded a couple of edges like parliament did all the really hard work and so just just the fact that they doubted that pearman had done that like was enough for him to say i'm not i'm not interested in this prize and that was one of the reasons why he rejected the fields medal it then you also rejected the clay prize so the poincare conjecture was one of the millennium prices there was a million dollar prize associated with that problem and that has to have to do with the fact that for them to attribute that price i think it had to be published on a journal yes the proof and again paramount principles of like interfered here and and he also just didn't care about the money he's like um clay i think was a businessman and he's like doesn't have to do anything with with mathematics i don't care about these like um that's one of the reasons why we rejected that yeah there's it's hard to convert into words but at mit i'm distinctly aware of the distinction between when i enter a room there's a certain kind of music to the way people talk when we're talking about ideas versus what that music sounds like when we're talking when it's like bickering in the space of like whether it's politics or funding or egos it's a different sound to it and i'm distinctly aware of the two and i kind of sort of to me personally happiness what was just like swimming around the one that like is the political stuff or the money stuff and all that uh or egos uh and i think that's probably what prominent is as well like the moment he senses there's any as with a feels matter like the moment you start to have any kind of drama around credit assignment all those kinds of things it's almost not that it's important who gets the credit it's like the drama in itself gets in the way of the exploration of the ideas or the fundamental thing that makes science so damn beautiful and and you can really see that there's also a product of that russian school of like doing science and you can see that that um that people were you know during the cold war a lot of mathematicians they were not making any money they were doing math for the sake of math like for the intellectual pleasure of like solving a difficult problem yeah and you know even even if it was a flawed system and there were a lot of problems with with that there's these they were able to to actually achieve these and uh there were a lot of imperiment for me is the perfect product of that it just cared about like working on tough problems he didn't care about anything else it was just math you know pure math yeah there's a like for the broader audience i think another example of that is like professional sports versus olympics i've especially in russia i've seen that clear distinction where because the state manages so much of the olympic process in russia as people know the steroids yes yes yes but outside of the steroids thing uh is like the athlete can focus on the pure artistry of the sport like like not worry about the money not just in the way they talk about it the way they think about it the way they define excellence versus like in the perhaps a bit of a capitalist system in united states with american football with baseball basketball so much of the discussion is about money now of course at the end of the day it's about excellence and artistry and all that but when the culture is so richly grounded in discussions of money and uh sort of this capitalistic like uh merch and businesses and all those kinds of things it changes the nature of the activity and it's in a way that's hard again to describe in words but when it's purely about the activity itself it's almost like you quiet down all the noise enough to hear the signal enough to hear the beauty like whenever you're talking about the money that's when the marketing people come and the business people the non-creators come and they fill the room and there's they create drama and they know how to create the drama and the noise as opposed to people who are truly excellent at what they do the the person in their arena right like when you remove all the money and you just let that thing shine that's when true excellence can and can come out and that was of the few things that work with the communist system the soviet union to me at least as somebody who loves sport and loves mathematics and uh science that worked well removing the money from the picture uh you know not that i'm um not that i'm saying poverty is good for science there's some level in which not worrying about money is good for science it's a weird i'm not exactly sure what to make of that because capitalism works really damn well yeah but it's um it's tricky how to find that balance one fields metal list that is interesting to look at and i think you mentioned it earlier but is cedric villani which is might be the only uh phil's medalist that is also a politician now but so it's this it's this brilliant french mathematician that won the fields medal and and after that he decided that one of the ways that he could have could have you know the biggest leverage kind of is in pushing science in the direction that he thinks science should go would be to to try to go into politics and so that's what he did and and uh and the israel i'm not sure if he has won in any election but i think he's running for a mayor of paris or something like that but it's this brilliant mathematician that before winning the fields medal had only been just a brilliant mathematician but but after that he decided to go into politics to to try to to have an impact and try to change some of the things that he he would complain about before so so there's that component as well yeah and i've always thought mathematics and science should be like like james bond would in my eyes i think be sexier if you did math like we should as a society put excellence in mathematics at the same level as being able to kill a man with your bare hands like those are both useful feature like that's admirable it's like oh like that makes you like that makes the person interesting like being extremely well read about history or philosophy being good in mathematics being able to kill a man with bare hands those are all the same in my book so i think all are useful for action stars and i think the society will benefit for uh for giving more value to that like one of the things that bothers me about american culture is the i don't know the right words to use but like the nerdiness associated with science like like in i i don't think nerd is a good word in in american culture because uh it's seen as like weakness there's like images that come with that and it's fine you could you could be all kinds of uh shapes and colors and personalities but like to me uh having sophisticated knowledge in science being good at math doesn't mean you're weak in fact it could be the very opposite and so it's it's an interesting thing because it was very much differently viewed in the uh in the soviet union so i know for sure as an existence proof that it doesn't have to be that way but it um i also feel like we lack a lot of like role models in terms if you ask people like mention to mention one mathematician that they know that is alive today i think a lot of people would struggle to answer that question um and i also think i love neil degrasse tyson okay but there is uh having more role models is good like different kinds of personalities he he has kind of fun and and it's very it's uh like bill nye the science guy i don't know if you guys know him so like that spectrum that yeah but there there's not like feynman is no longer there uh those kinds of personalities even carl sagan yeah like a seriousness that's like not playful like not apologetical yeah exactly not apologetic about being knowledgeable like like in fact like the kind of energy where you feel uh self-conscious about not having thought about some of these questions right just like when i see james bond i feel bad about that i don't have never killed a man like i need to make sure i fix that right that's the way i feel so the same way i want to feel like that way well carl sagan talks i i feel like i need to have that same kind of seriousness about science like if i don't know something i want to i want to know well what about terence tao he's kind of a superstar what are your thoughts about him true he's probably one of the most famous mathematicians alive today and problem of i mean regardless of like is of course uh he want to feel the fields medal is really smart and talented mathematician um it's also like a big inspiration for us at least for some of the work that we do with formats library so terence style is is known for having you know a big blog and he's pretty open about like his research and he also he tries to make his work as public as possible um through his blog posts um in fact there's a really interesting um problem that got solved a couple of years ago so tao was working with um on a problem on an erdos problem actually so if paul erdogan was this mathematician from hungary and it was known for like um the airdosh for a lot of things but one of the things that he was also known was for the erdos problem so he was always like um creating these problems and usually associating prizes with those problems and a lot of those problems are still open like and and there will be some of them will be open for like maybe a couple hundred years and i think that's actually an interesting hack for him to collaborate with future mathematicians you know his his name will will keep coming up in you know for future generations but so tao was working on one of these problems called the erdog discrepancy and he published a blog post on like about that prop about that problem and he reached like a dead end and then um all of a sudden there was this guy from from germany that wrote like a comment on his blog post saying okay like some of the so this problem is like a sudoku like flavor and some of the machinery that we're using to solve the sudoku could be used here and that was actually the key to solve their those discrepancy problems so the there was a comment on his blog and i think that that that for me is an example of like how to do again going back to collaborative science online um and the power that it has but taw is is also like pretty public about uh like some of the struggles and of of being a a mathematician like and and even he wrote about some of the unintended consequences of having extraordinary ability in a field and used himself as an example when he was growing up he was extremely talented in in mathematics from a young age like todd was a person he won an uh medal in like one of the imo's at the age i think was a gold medal at the age of 10 or something like that and so he mentioned that when he was growing up like and especially in college when he was in a class that he enjoyed it didn't it just came very natural for him and he didn't have to work hard to just ace the class and when he found that the class was boring like it didn't work and he barely passed barely passed some i think in college he almost failed two classes and and he was talking about that and how he brought those studying habits or like uh in existence of studying habits when he went to prison princeton for his phd and in for instance when he you know started kind of delving into more complex problems and classes he struggled a lot because he didn't have that those those habits like it wasn't taking notes and it was he wasn't studying hard when he when he faced problems and he almost failed out of his his phd he almost failed his phd exam and um it talks about like having this conversation with with this advisor and the advisor pointing out like you're not this is not working you might have to get out of the program and like how that was a kind of a turning point for him and um and like it was super important in his career so i think tao is also like this figure that apart from being just an exceptional mathematician he's also pretty open about you know what what it takes to to to be a mathematician and some of the struggles of these type of careers and and i think it's that's super important in many ways he's a contributor to open science and open humanity so he's being an open human through by communicating uh scott aaronson is another in computer science world who's a very different style very different style but there's something about a blog that is authentic and real and just gives us a window into the into the mind and soul of of of these brilliant folks so it's it's definitely a gift let me ask you about fermat's library on twitter which uh i mean i don't know how to describe it people should definitely just follow from ours library on twitter i i keep following and unfollowing for my library because because uh it's so it it gives when i follow it um leads me on down rabbit holes often that um that um that are very fruitful but but anyway so the the the posts you do with the on twitter are just these beautiful are things that reveal some beautiful aspect of mathematics um is there um is there something you could say about the approach there yeah and um maybe maybe broadly what you find beautiful about mathematics and then more specifically how you convert that into a rigorous process of revealing that in tweet form that's a good point i think there's something about math that you know a lot of the mathematical content and you know paper papers are like little proofs um you know has in a way sort of an infinite half-life what i mean by that is that if you look at like euclid's elements it's as valid today as it was when it was created like 2 000 years ago and that's not true for a lot of other scientific fields um and so in regards to twitter i think there's also a very it's a very undex underexplored platform from a learning perspective i think if you look at content on twitter it's very easy to consume it's very easy to read um and especially when you're trying to explain something you know we humans get a dopamine hit if we learn something new and that's a very very powerful feeling and that's why you know people go to classes when you have a really good professor you know it's it's looking for those dopamine hits and and and and that's something that we try to explore when we're producing content on twitter imagine if we we could if you would on a line to a restaurant you could go go to your phone to learn something new instead of social going to a you know social network to just and so and i think it's very hard to to sometimes to kind of provide that feeling because you need to sometimes digest content and and put it in a way you know that it feeds 280 characters um and and it requires a lot of sometimes time to do that even though it's easy to consume it's hard to make but once you are able to to provide that eureka moment to people like that's very powerful they get that dopamine hit and like you create this feedback cycle and people come back for for more and in twitter compared to like you know an online course for a book you have a zero percent dropout so people will will read the content the content so that it's it's like it's part of the creators like the person that is creating the content if you're able to actually get that feedback cycle it's super super powerful yeah but some of the stuff is like like how the heck do you find that and and i don't know why it's so appealing it uh like uh this is from uh what is it a couple days ago i'll just read out the number two three four five six seven eight nine is the largest prime number with consecutive increasing digits i mean that is so cool that's like some weird like glimpse into some deep universal truth even though it's just a number i mean that's like so arbitrary like why why is it so pleasant that that's a thing but it is in some way it's almost like it is a little glimpse at some much bigger like um and and i think like especially if we're talking about science there's something unique about you go and with a lot of the tweets you go sometimes from a state of not knowing something to knowing something and that is very particular to science science math physics and that again is extra extremely addictive and that's that's how i i i feel about that and um that's why i think people engage so much with with our tweets and go into rabbit holes and then they you know we start with prime numbers and all of a sudden you are spending hours reading number theory things and you go into wikipedia and you lose a lot of time there but well the variety is really interesting too there's human things there's uh there's physics things there's like numeric things like like i just mentioned but there's also more rigorous mathematical things there's stuff that's tied to the history of math and the proofs and this visual there's animations that are looping animations that are incredible that reveal something there's uh andrew wiles i'm being smart and this is just me now like ignoring you guys and just going through oh yeah we're a bit like math drug dealers we're just trying to get you hooked you know we're trying to give you that hit and trying to get you hooked yes some people are brighter than others but i really believe that most people can really get to to quite a good level of mathematics if they're prepared to deal with these psychological issues of how to handle the situation of being stuck yeah yeah there's some truth to that that's truth i feel that's like really it's some truth in terms of research and also about startups you're they're stuck a lot of the time before you you get to a breakthrough and and it's difficult to endure that process of like being stuck and because you're not trying to to be in that position um i feel uh yeah that's yeah most people are broken by the stuckness or like they're destroy like uh i i've i've been very cognizant of the fact that more and more social media becomes a thing like distractions become a thing that that moment of being stuck is uh your mind wants to to go do stuff that's unrelated to being stuck and you should be stuck i'm referring to small stucknesses like you're like trying to design something and it's a dead end basically little dead ends on dead ends and programming dead ends and trying to think through something and then your mind wants to like like like uh this is the problem with this like work-life balance culture is like take a break like as if taking a break will solve everything sometimes it solves quite a bit but like sometimes you need to sit in a stuckness and suffer a little bit and then take a break but you you definitely need to be and like most people quit from that psychological battle of being stuck and so success is people who who who uh persevere through that yeah yeah and and in the creative process that's also true i was the other day i was i think was reading about is this um what is his name ed sheeran like the musician yeah was talking a little bit about the creative process and using was using this analogy of a faucet like where you when you turn on a faucet as like the dirty water coming out in the beginning and you just have to you know keep trusting that at some point your clean clean clear water will come out but you have to endure that process like in the beginning it's going to be dirty water and and and just you know embrace that yeah actually this uh the entirety of my youtube channel and this podcast have been following that philosophy of dirty water like i've been you know i do believe that like you have to get all the crap out of your system first and uh sometimes it's it's all sometimes it's all crappy work i mean i tend to be very self-critical but i do think that quantity leads to quality for some people it does for my the way my mind works is like just keep putting stuff out there keep creating and uh the quality will come as opposed to sitting there waiting not doing anything until the thing seems perfect because the perfect may never come but just just on like on on our twitter like profile i really and sometimes when you look on some of those tweets they might seem like pretty kind of um you know why is this interesting it's like so raw uh like it's just a number but i really believe that especially with math or physics it is possible to get everyone to love math or physics even if you think you hate it it's it's not a function of the student or the person that is on the other side i think is just purely a function of like how you explain uh hidden beauty that they hadn't realized before it's not easy but i think it's like a lot of the times it's on like on the creator's side to to be able to like show that beauty to the other person i think some of that is native to to humans we just have that curiosity and you look at small toddlers and babies and like them trying to figure things out and there's just something that is born with us that we we we want for that understanding we want to figure out the world around us and and so yeah it shouldn't be like uh whether or not people are going are going to to enjoy it like i i i also really believe that everybody has that capacity to fall in love with with math and physics you mentioned startup what do you think it takes to build a successful startup yeah that it's what what louise was saying that um you need to in to be able to endure being stuck and and i think the best way to put it is that startups don't have a linear reward function right you oftentimes don't get rewarded for effort and and in most of our lives we go through these processes that do give you those small rewards for effort right in school you study hard generally you'll get a good grade and then you good you get like good grades ever or you get grades every semester and so you're you're slowly getting rewarded and pushed in the right direction for for startups and startups are not the only thing that is like this but for startups it's you know you can put in a ton of effort into something that and then get no reward for it right it's like like sisyphus boulder where you're pushing that boulder up the mountain and and and you get to the top and then it just rolls all the way back down and and so that's something that i think a lot of people are not equipped to deal with and can be incredibly demoralizing especially if that happens more than than a few times and so but i think it's absolutely essential to to power through it because uh by the nature of startups it's often times you know you're dealing with with with non-obvious ideas and things that there might be contrarian and so you're gonna you're gonna run into into that a lot you're gonna do things that are not gonna work out uh and you need to be prepared to deal with that but but we're not coming out of college you're you're just not equipped i'm not sure if there's a way to train people to deal with those non-linear reward functions but it's definitely i think one of the most difficult things to you know about doing a startup and also happens in research sometimes you know we're talking about the default studies being stuck you just you know you don't like you try things you get zero results you close doors you constantly closing doors until you you know find something and um yeah that is a big thing what about sort of this point when you're stuck there's a kind of decision whether you if you have a vision to persist through through with this direction that you've been going along or what a lot of startups do or businesses is pivot how do you decide whether like to give up on a particular flavor of the way you've imagined the design and to like adjust it or completely like alter it i think that's a core question for startups that i've asked myself exactly and like i've never been able to come up with a great framework to make those decisions um i think that's really at the core of uh yeah out of a lot of the the toughest questions that that people that's that started a company have to deal with um i think maybe the best framework that i i was able to figure out like when you run out of ideas you just you know you're exploring something it's not working you try it in a different angle you know you try a different business model yeah when you run out of ideas like you don't have any more cards just switch and yeah it's not perfect because you also it's you have a lot of stories of startups with like people kept pushing and then you know that paid off and then you have uh philosophies there's like fail fast and pivot fast um so it's you know it's hard to you know balance these two worlds and understand what is the best framework and i mean if you look at four miles library your maybe you can correct me but it feels like you're an operating in a space where there's a lot of things that are broken and or could be significantly improved so it feels like there's a lot of possibilities for pivoting or like how do you revolutionize science how do you revolutionize the aggregation the the annotation the commenting the community around information about knowledge structured knowledge i mean that's kind of what like stack overflow and stack exchange has struggled with to come up with a solution and they've come up i think with an interesting set of solutions that are also i think flawed in some ways but they're much much better than the alternatives but there's a lot of other possibilities if we just look at papers as we talked about there's so many possible revolutions and they're a lot of money to be potentially made in those revolutions plus coupled with that the benefit to humanity and so like you're sitting there like i don't know how many people are legitimately from a business perspective playing with these ideas it feels like there's a lot of ideas here true there is are you right now grinding in a particular direction like is there a like a five-year vision that you're thinking in your mind for us it's more like a 20-year vision in the sense that uh we we've consciously tried to make the decision of so we so we run fermat says it's a side project and it's a separate in the sense like it's not what we're working on full-time and uh but our thesis there is that we actually think that it's that's a good thing at least for for this stage of vermont's library um and also because some of these projects you just if you're coming from a start from a startup framework you probably try to try to fit every single idea into something that can change the world within three to five years and there's just some problems that take longer than that right and so you know we're talking about archive and i'm very doubtful that you could grow like archive into what it is today like within two or three years no matter how much money you throw at it there's just some things that can take longer but you need to be able to power through the the the time that it takes um but if you look at it as okay this is a company this is a startup we have to grow fast we have to raise money then uh then sometimes you might forgo those ideas because of that um because they don't very well fit into the the typical startup framework and so for us formats it's something that we're okay with growing with having it grow slowly and and maybe taking many years and and and that's why we think it's it's not a bad thing that it is a side project because it makes it much more um acceptable in a way and that to to to be able to be okay with that that said i think what happens is if you keep pushing new little features new little ideas i feel like there's like certain ideas will just become viral like and then you just won't be able to help yourself but it'll revolutionize things it feels like there needs to be that needs to be but there's um opportunity for viral ideas to change science absolutely and maybe we don't know what those are yet it might be a very small kind of thing maybe you don't even know if should this be a for-profit company that's the wikipedia question yeah um is that a lot of questions like really fundamental questions about this space that we've we've talked about i mean you take wikipedia and you try to run it as a startup and by now we'd have a paywall you'd be paying 9.99 a month to to read more than 24 i mean that's that's one view yeah the other the ad driven model so they rejected the ad driven model i don't know if we could i mean this is a difficult question you know if archive was supported by ads i don't know if that's bad for archive if vermont's library was supported by ads i don't know i don't i'm not it's not trivial to me i'm unlike i think a lot of people uh i'm not against advertisements i think as when done well are really good i think the problem with facebook and all the social networks are the way the lack of transparency around the way they use data and the lack of control the users have over their data and not the fact that data is being collected and used to sell advertisements it's a lack of transparency lack of control if you if you do a good job of that i feel like it's really nice way to make stuff free yeah for example it's like stack overflow right yeah i think they've done an okay a good job with that even though as we said like they're capturing very little of the value that they're putting out there right but but it makes it a sustainable company and and they're providing a lot of it's a fantastic and very productive community let me ask a a ridiculous tangent of a question where he's you wrote a paper on a on game of thrones battle of winterfell just as a side little i i'm sorry i noticed i'm sure you've done a lot of ridiculous stuff like this i just noticed that particular one by ridiculous i mean you're ridiculously awesome can you describe the the approach in this work which i believe is a legitimate publication so going back to the original like uh when we were talking about the backstory of of papers and the importance of that so this is actually you know it was when the last season of the the show was airing uh this was a during a company lunch we there was in in the last season there's the there's a really big battle against the the forces of evil and the you know forces of good and this is called the battle of winterfell and um in this battle there are like these two armies and there's a very particular thing that they have to take into account is that in the army of dead like if someone dies in the army of the living like that person is gonna you know be a reborn as a soldier in the army of the dead yes and so that was an important thing to take into account and the initial conditions as you specify it's about a hundred thousand on each side exactly so i was able i was able to like based on some images like on previous episodes to figure out what was the size of the armies and so what i want what we wanted to do what we were theorizing was like how many soldiers does like a a soldier on the army of the living has to kill in order for them to be able to this to destroy the army of the dead without like losing because every time one of the good soldiers died is going to turn into like the other side and so it's so i we we were theorizing that and and i wrote a couple of uh differential equations and um i was able to figure out that based on the size of the armies i think i think was the ratio had to be like 1.7 so it had to kill like 1.7 um soldiers like the army of the dead in order for them to win the battle well yeah that's that's science it is it's it's most powerful and this is also somehow a pitch for uh like a hiring pitch in a sense like this is the kind of uh yeah before the science you do it exactly yeah well turned out to be you know as as is for people that have watched these shows is like they know that every time you try to predict something that is going to happen it's going to you're going to fail miserably and that's what happened so it was not not at all important for the show but yeah we ended up like putting that out and there was a lot of people that shared that i think was some like elements of the of the show the cast of the show that actually retweeted that and shared that at first so it was fun i would love if this kind of calculation happened uh like during the making of the show or the you know i love it like in um for example i now know um alex garland the director of ex machina and i love it he doesn't seem to be some not many people seem to do this but i love it when directors and people who wrote the story really think through the technical details like whether it's knowing like how things even if it's science fiction if you were to try to do this how would you do this like stephen wolfram and his son were were collaborating with the movie arrival in designing the alien language how you communicate with aliens like how would you really have a math-based language that uh that could span the alien and uh being and the human being so i i love it when they have that kind of regular the martian was also big on that like the book in the movie was all about like can we actually is this plausible can these happen it was all about that and that can really bring you in like the sometimes the small details uh i mean the guy that wrote the martian book is another book that is also filled with those like things that when you realize that okay these are grounded in in science can just really bring you in yeah right like there's a book about a colony on the colony on the moon and he goes about like all the details that would you know be required about setting up a colony in the moon and like things that he wouldn't think about like the the fact that um they would you know it's hard to bring like uh air to the moon say so they wouldn't like how do you make that breathable that environment breathable you need to bring oxygen but like you you you probably wouldn't be bring nitrogen so what you do is like instead of having a an atmosphere that is 100 oxygen you like decrease the pressure so that you have the same ratio of oxygen on earth but like lowering the pressure here and so like things like water boils at the lower temperature so people would would have coffee and the coffee would be colder like there was a problem in this uh environment in the moon so like and these are like small things in the book but i studied physics so like when i read this i that throws me into like a tangents and i start researching that and it's like i really like to read books and and watch movies when they go to that level of detail uh uh about science yeah i think interstellar was one where they also consulted heavily with with the number of yeah i think even resulted in a couple of papers a couple papers about like the black hole uh visualizations and um yeah but there's and there's even more examples of interesting science around like these fantasy we were reading at some point like these guys that were uh trying to figure out if if the tolkien's middle earth if it was uh round if it was like a sphere if it was like based on the map and some of the references in the in the books and so uh yeah we actually i think we tweeted about that yeah we did based on the distance between the cities you can actually prove that that could be like a map of a sphere or like a spheroid and and you can actually calculate the radius of that planet uh that's fascinating i mean yeah that's fascinating but there's something about like calculating the number like exactly the calculation you did for for the battle winterfell is um there's something fascinating about that because it's not like being that's very mathematical versus like grounded in physics and that's really interesting i mean that's like injecting mathematics into fantasy there's there's something um i see magical about that and and that for me that's why i think it's also when you look at things like like uh fermat's last theorem like problems that are very kind of self-contained and simple to state yeah i think like that's the same with that paper it's very easy to understand the boundaries of the problem you know um and and that for me that's why those and that's why math is so appealing and those like problems are also so appealing to the general public it's not that they look simple or that people think that they're easy to like solve but i feel that a lot of the times they are almost intellectually democratic because everyone understands the starting point you know you look at fermat's last theorem everyone understands like is the this is the the universe of the problem and the same maybe with that paper everyone understands okay these are the starting conditions and um and and yeah that the fact that it becomes intellectually democrat and i think that's a huge motivation for people and that's why so so many people gravitate towards these like riemann hypotheses or vermont's last theorem or that simple paper which is like just one page it's very simple and i just talked to somebody i don't know if you know who he is jaco willink who is uh this person who among many things loves military tactics so he would probably either publish a follow-on paper maybe you guys should collaborate but he would see the fundament the basic assumptions that he started that paper with is flawed because you know there's like dragons too right there's like like you have to integrate tactics because not it's not it's not a homogeneous system it's not you i don't take into account the dragons and like and he would say tactics fundamentally change the dynamics of the system and so like that's what happened so uh yeah so at least from a scientific perspective he was right but he never published so there you go uh let me ask the most important question you guys are from portugal both yeah so who is the greatest soccer player footballer of all time yeah i think we're a little bit biased on this topic but uh i mean i have maradona i i have a huge i have a you know tremendous respect for for what um here we go this is the political issue we can convince you i i i mean i have tremendous respect for what ronaldo has achieved in in his career and and i think soccer is one of those sports where i think you can get to maybe be one of the best players in the world we if you just have like natural talent and even if you don't put a lot of hard work and discipline into soccer you can be one of the best players in the world and i think ronaldo is kind of like of course he's naturally talented but yeah exactly from portugal um and and not uh not the brazilian in this case and so um and ronaldo put like came from nothing he he's known from being probably one of the hardest working athletes in the game and and i see that sometimes a lot of these discussions about the best player a lot of people train tend to gravitate towards like um you know this person is naturally talented and the other person has to work hard and so and so as if it was bad if he had to work hard to to be good at something and i think that you know the the i think so many people fall into that trap and the reason why so many people fall into that trap is because if you are saying that someone is good and achieved a lot of success by working hard as opposed to achieving success because it has some sort of god-given natural talent then you can't explain why the person was born with that what does it tell you about you it tells you that maybe if you work hard on a lot of fields you could have could accomplish a lot of great things and i think that's hard to digest for a lot of people and and that way ronaldo's inspiring that i think so you find hard work that's probably but he's he's way too good looking that's nice you know that's the yeah i don't like him probably no i like the part of the hard work and like of him being like one of the hardest working athletes in in soccer so he is to you the greatest of all time is he up there is he would be number one okay do you agree with this thing oh hardly disagree well i definitely disagree i mean i i like him very much he works hard i admire i admire you know um would like he's an incredible uh a goal scorer right um but i so first of all leo messi and there was some confusion because i've kept saying maradona is my favorite player but i i think i think leo has surpassed them so uh um it's messy that mardonna then pele for me but the the reason is is um there's certain aesthetic definitions of beauty that i admire whether it came by hard work or through god-given talent or through anything and it doesn't it doesn't really matter to me there's certain aesthetic like genius when i when i see it to me and uh especially it doesn't have to be consistent it is in the case of messi in a case in the ronaldo but just even moments of genius which is where maradona really shines it i even if that doesn't translate into like results and goals being scored right right and that's the challenge like they did that because that's where people that tell me that leo messi's never even on strong teams have led his the national team people as part of the world cup right as really important and to me no it's the moment like winning to me was never important what's more important is the moments of genius and but you're you're talking to the human story and um yeah cristiano ronaldo definitely has a beautiful human story yeah and i think you can't i for me it's hard to decouple those two um i i don't i don't just look at you know the the list of achievements but i like how he got there and how he keeps pushing the boundaries at like almost 40 yeah and how that sets up an example like maybe 10 years ago i wouldn't have ever imagined that like one of the top players in the world could be a top player at like 37 or but so and there's an interesting ten the human story is really important but like if you look at ronaldo he's like he's somebody like kids could aspire to be but at the same time i also like maradona who like is a as a tragic figure in many ways it's like the you know the drugs the the temper all of those things that's beautiful too like i don't necessarily think to me the flaws are beautiful too in in athletes i don't think you need to be perfect i agree uh from a personality perspective those flaws are also beautiful so but yeah there is something about hard work and uh there's also something about the being an underdog and being able to carry a team uh that's that's an argument from maradona i don't know if you can make that argument for messi and ronaldo either because they've all played on superstar teams for most of their lives so i don't know how it you know it's it's difficult to know how they would do um when they had to work like did what mardonna had to do to carry a team on his shoulders true and pele did as well and so depending on the the context yeah maybe you could argue that within portuguese national team but they were we have a good team uh yeah but maybe with what maradona did with you know naples and and a couple other teams it's it seemed incredible this is the beauty of the game that you know we're talking about all these different players that have or especially you know if you're comparing messi and ronaldo that have such different you know styles of play and also even their bodies are so different and and and but these two very different players can be at the top of the game and that's not that's the they're not a lot of other sports where you where you have that you know like you have kind of a mental image of a basketball player and like the the top basketball players kind of fit that mental image and and they look a certain way and um but for soccer there's so there's it's it's not so much like that and and that's i think that's that's beautiful uh but that's that really adds something to the sport well do you play soccer yourself have you played that in your life what do you find beautiful about the game yeah i mean it's one of the i'd say it's the biggest sport in portugal and so growing up we played a lot did you see the paper from deepmind i didn't look at it where they're like uh doing some uh analysis on soccer strategy yeah interesting i saved that paper uh i haven't read it yet um it's actually i i when i was in college i actually did some research on on applying um machine learning and statistics in sports and in our ca in our case we're doing it for basketball but uh what they're effectively trying to do was have you ever watched moneyball like yeah so they're trying to do something similar to taking that in this case basketball taking a statistical approach to to to basketball um the interesting thing there is that baseball is much more about having these discrete events that happen kind of in similar conditions and so it's easier to take a statistical approach to it whereas basketball is a much more dynamic game it's harder to measure um it's hard to to replicate these conditions and so you you have to think about it in a slightly different way and so we were doing work on that and working like with the celtics to analyze the the the data that they had like they had these cameras in the in the arena they were tracking the players and so you so they have they had a ton of data but they didn't really know what to do with it and so we were doing work on that and and and soccer is maybe an even a step further it's it's right it's a game where you don't have as many in in basketball you have a lot of field goals and so you can measure success uh soccer it's it's right it's more of a poisson process almost where it's like you have a goal like or two and again in terms of metrics i wonder if there's a way and i've actually have thought about this in the past never coming up with any good solution if there's a way to definitively say whether it's messier and now they're the greatest of all time like honestly sort of measure interesting like convert the game of soccer into metrics like you said baseball but like those moments of genius like pat like um you know if it's just about goals or passes that led to goals that feels like it doesn't capture the genius of them yeah they'll be like you know like like you kind of do you have more metrics for instance in chess right and you can try to understand how hard of a move there was you know there's like bobby fischer has this move that like that it's i think it's called the move of the century where uh you have to go so deep into the tree to understand that that was the right move and you can quantify it how hard it was so it'd be interesting to try to think of those type of metrics but say yeah for soccer computer vision unlocks some of that for us that's that's one possibility i have a cool idea a computer vision product likes that you could build for soccer i'm taking notes if you could detect the ball and like imagine that um this seems like totally doable right now but like if you could detect when the ball enters one of the goals and like just had like um you know a crowd cheering for you when you're playing soccer with your friends every time you score a goal or you had like the the champions league song going on yeah and like having that like you go play soccer with your friends you just turn that on and there's like a computer vision like program analyzes the ball detects the ball every time there's a goal like if you miss like there's a you know the fans are reacting to that and then it should be pretty simple by now it's like i think there's an opportunity there so yeah just throwing that i would go all out but by the way i did uh i've never released i was thinking of just putting on github but i did write exactly that which is the trackers for the players uh for the for the bodies of the player it's this is the hard part actually the detection of player bodies and the ball is not hard what's hard is very like robust tracking through time of each of those so like so i wrote a track of this pretty damn good this is this is that is that open source i know i've never released it because that's interesting because i thought like i need to i would this is the perfection thing because i knew it was going to be like it's going to pull me in and and it wasn't really that done and so i've never actually been part of a github project where it's like really active development and i didn't want to make it i knew there's a non-zero probability that will become my life for like a half a year that's uh just how much i love soccer and all those kinds of things and and ultimately it will be all for just the the joy of analyzing the game which i'm all for i remember you also like one of in one of the episodes you mentioned that you did also a lot of eye tracking analysis like joe rogan's that was the that was the research side of my life interesting yeah and you have that library right you you kind of downloaded all the episodes yep allegedly i and of course i didn't if you're a lawyer listening to this no it is i i was listening to the episode where you mentioned that and i was actually there was something that i and i might ask you for for access to that to allegedly that library uh but i was doing some not not regarding like eye tracking but i was playing around with um analyzing the distribution of silences on uh one of the joe rogan episodes so like i did that for the elon conversation where it's like you just take all the silences like after joe asked the question and elon responded and you plot that distribution and like and see how how that looks like yeah i think there's a huge opportunity especially long-form podcasts to do that kind of analysis bigger than joe exactly but it has to be a fairly unedited podcasts so that you don't cut the silence so one of the benefits i have like doing this podcast is like the the what we're recording today is there's individual audio being recorded like i have the raw information no it's when it's published it's all combined together and individual video feeds so even when you're listening which i usually don't i only show one video stream i i'll know i can track your blinks and so on um but yeah but ultimately the hope is you don't need that raw data because if you don't need the raw data for whatever analysis you're doing you can then do a huge number of products because there's so it's quickly growing now the number especially comedians there's uh quite a few comedians with with long-form podcasts and they have a lot of facial expressions they have a lot of fun and all those kinds of things and it's it's prone for analysis yeah and it's there's so many interesting things that that that idea actually sparked because i was watching a um a q a by by steve jobs and i think was at mit and then like people's like he did a talk there and then the q and a started and people started asking questions that i was i was working while listening to it and like someone asked the question and he goes like on a 20-second silence before answering the question i like i had to check if the if the video hadn't paused or something and and i was thinking about like like if that is a feature of a person like how long on average you take to respond to a question and if it's like that's fascinating it has to do with it like how thoughtful you are and if that changes over time well but it also could be this really fascinating metric because it also could be it's certainly a feature of a person but it's also a function of the question like if you normalize to the person you can probably infer a bunch of stuff about the question so it's a nice flag like it's a really strong signal the length of that silence relative to the usual silence they have so one the silence is a measure of how thoughtful they are and two the particular sounds doesn't measure how thoughtful the question was thoughtful the question was it's really interesting i mean yeah yeah i just analyzed elon's uh um episode but i think there's like room for exploration there i feel like the average they could do for comedians would be like i mean the time would be so small because you're trained to like i would think you're reacting to hecklers you're reacting to all sorts of things you have to be like so quick maybe right yeah but some of the greatest comedians are very good at sitting in the silence i mean there there's lucy kaye they played with that because you have a rhythm and you like um dave chappelle a comedian who did uh joe's show recently he has uh especially when he's just having a conversation he does long pauses it's kind of cool because it uh it's one of the ways to have people hang in your word is to play with the pauses to play with the silences and the emphasis and like mid-sentence there's a bunch of different things that uh it'd be interesting to really really analyze but still soccer to me is uh that's that that one that's fascinating just i just want a conclusive definitive statement about it's like there are so many soccer highlights of both messi and ronaldo i just feel like the raw data is there um because you don't have that with pele just remember yeah through but here's a huge amount of high def data then the the annoying the difficult thing and this is really hard for tracking and this is actually where i kind of gave up because i didn't really give much effort but i gave up to the the way that highlights or usually football match are filmed is they switch the camera so they'll they'll do a different switch perspective so you have to it's a really interesting computer vision problem when the perspective is switched you still have a lot of overlap about the players but the perspective is sufficiently different that you have to like recompute everything so i there there's two ways to solve this so one is doing it the full way where you're constantly doing the slam problem you you're doing a 3d reconstruction the whole time and projecting into that 3d world but you could also there could be some hex that i wonder like some trick where you can hop like when the perspective shifts do a high probability tracking hops from one object to another but i i thought especially in exciting moments when when uh when you're passing players like you're doing a single ball dribble across players and you switch perspective which is when they often do when you're making a run on goal if you switch your perspective it's it feels like that's going to be really tricky to get right automatically but in that case i feel like if somebody released that data set or it's like you just have all like these this data set a massive data set of all these games from from say ronaldo and messi like and just you just add that in like whatever csv format and some some publicly available data set like that i feel like people would just there there would be so many cool things that you could do with it and you just set it free and then like the world would like do its thing and then like interesting things would come out of it by the way i have this data set so the two things that i've did of this scale uh is soccer so it's body pose and ball tracking for soccer and then um i tr it's pupil tracking and blink tracking for it was joe rogan and a few other podcasts that i did so those are the two data sets i have did you analyze any of your podcasts no i i think i really started doing this podcast after after doing that work and it's difficult to maybe i'd be afraid of what i find i'm already annoyed with my own voice and video like editing it but perhaps that's the honest thing to do because uh one useful thing about doing computer vision about myself is like i know what i was thinking at the time so you can start to like connect the particular the behavioral peculiarities of like the way you blink the way you squint the way you close your eyes like talking about details there's it's like for example i just closed my eyes is that a blink or no like figuring that out in terms of timing in terms of the blink dynamics is tricky it's very doable i i think there's universal laws about what is a blink and what is a closed eye and all those things plus makeup and eyelashes i actually um have annoyingly long eyelashes so i remember when i was doing a lot of this work i i would cut off my eyelashes when like especially it was funny like female colleagues were like what the fuck are you doing like those no keep the eyelashes but because it got in the way made the computer vision a lot more difficult but super interesting topics yeah but speaking about the one uh still on the topic of the data sets for sports there's one um one paper that and i actually annotated it on fermat and uh it's it was published in uh 90s 90s i believe 90s or 80s i forget but they're you the researcher was effectively looking at the hot and phenomena in basketball right so whether like the fact that you just made a field goal um if you know if on your next attempt if you're more likely to make it or not um and it was super interesting because i mean he pulled like i think 100 undergrads and i think from stanford and cornell and asking people like do you you think that's that you have a higher likelihood of making your free throw if you just just made one and i think it's like 68 68 said yes they believe that and and then he looked at the data and this was back in as i said like a few decades ago and so i think he had a data set of about he looked at it specifically for free throws and he had a data set of about 5 000 free throws and and effectively what he found was that specifically in the case of free throws he didn't for the aggregate data he didn't find um that he couldn't really spot that correlation that hot end correlation so if you made the first one you weren't more likely to to make the second one what he did find was that they were just better at the second one because you just got like maybe a tiny practice and you just you attempted once and then and then you're going to be better at the next one and then i i then i went and there's a data set on kaggle that has like 600 000 free throws and i reran the the same computations and and confirmed like you can see a very clear pattern that they're just better at their second free throw um that's interesting because i think there's similar that kind of analysis is so awesome because i think with tennis they have like uh like a fault like when you serve they have analysis of like are you most likely to miss the second serve if you missed first obviously um yeah i think that's the case so that integrates that's so cool when psychology is converted into metrics in that way and in sports it's especially cool because it's such a constrained system that you can really study human psychology because it's repeated it's constrained so many things are controlled which is something you rarely have in in the wild psychological experiment so it's cool uh plus everyone loves it like sports is really cool to analyze people actually care about the results yeah um i still think well like i yeah and i will definitely publish uh this work on messi versus ronaldo and i'd love to read it objective fully objective to peer review um yeah this is very true this is not past peer review um let me ask sort of um an advice question to uh to young folks you've explored a lot of fascinating ideas in your life you've built a startup worked on physics worked in computer science what advice would you give to young people today in high school maybe early college about life about career about science and mathematics i remember like i i read like i remember reading that um ponkario was once asked by um a french journal about his advice for young people and what was his teaching philosophy and he said that like one of the most important things that parents should teach their kids is how to be enthusiastic um in regards to like the mysteries of the world and that he said like striking that balance was actually one of the most important things between like in education you know you want to have your kids be enthusiastic about the mysteries of the world but you also don't want to traumatize them like if you really force them into something and i think like especially if you're young i think you you should be curious and i think you should ex explore that curiosity to the fullest to the point where you even become almost as an expert on that topic and now and you might start with something that it's small like you might start with you know you're interested in numbers and how to factor numbers into primes and then all of a sudden you go and and you're like lost in number theory and you discover cryptography and then all of a sudden you're buying bitcoin and i and i think you should do these um you should really try to fulfill this curiosity and you should live in a society that allows you to fulfill this curiosity which is also important and i think you should do these not to get to some sort of status or fame or money but i think this is the way this iterative process i think this is the way to find happiness and and i think this is also allows you to find the meaning for your life i think it's all about like being curious and being able to fulfill that curiosity and that path to fulfilling that uh your curiosity yeah the the the start small and let the fire build is kind of interesting way to think about it and you never know where you're gonna end up it's it's like for instance from us it's just a really good example we started like just by doing this as an internal like thing that we did with in the company and then we started putting out there and now a lot of people follow it and know about it and so um and you still don't know where females libra is going to end up actually true exactly so um yeah i think that would be my piece of advice with very limited experience of course but yeah yeah i agree i agree uh i mean is there something in from particular journal from the computer science versus physics perspective uh do do you regret not doing physics do you regret not doing computer science which one is the the wiser the better human being this is messy versus ronaldo those are very i i don't know if you would agree but they're kind of different disciplines true yeah very much so um i actually actually uh i was i i had that question in my mind i i took physics classes uh as an undergrad uh or like besides what i had to take and um it's definitely something that i considered at some point um and and that that i i i do feel like later in life that might be something that i'm not sure if regret is is the right word but it's it's kind of something that i can imagine in an alternative universe what would have happened if i if i've gone into physics um i try to think that like well depends on what your path ends up being but that it's it's not super important right like exactly what you decide to major on like i think there's there's um i think tim urban like the blogger had a good visualization of this where it's like you know like he he has a picture where you have all sorts of paths that he could pursue in your life and then maybe you're in the middle of it and so there's maybe some paths that are not accessible to you but like the tree that is still in front of you gives you a lot of optionality and so um there's two lessons to learn from that like we have a huge number of options now and probably you're just one to reflect like to try to uh derive wisdom from the one little path you've taken so far may be flawed because there's all these other paths you could have taken yeah so it's like uh so one it's inspiring that you can take any path now and two it's like you you the path you've taken so far is just one of many possible ones but it does seem that like physics and computer science both open a lot of doors in a lot of different doors it's very interesting it is i i like in this case like and especially in in our case because i could see the difference i studied i i did i went to college in europe and uh went to college here in the us so i could see the differences like in the european system is um more rigid in the sense that when you decide to study physics you don't have a lot especially in the early years you don't have a lot of um you can't choose to take like a class from like computer science course or something like that you don't have a lot of freedom to explore in that sense in university as opposed to here in the us where you have more freedom and i think um i think that's important i think that's what constitutes you know a good kind of educational system is one that gravitates towards the interests of a student as as you progress but i think in order for you to do that you need to explore different areas and i i felt like if i had a chance to take say more computer science class when i was in college i would have probably have taken those classes but um yeah but i ended up like focusing maybe too too much in physics and i think you're at least my perception is that you can explore more more fields but there is a kind of it's funny but physics can be difficult so i don't see too many computer science people than exploring into physics it's only like the one the not the one but one of the beneficial things of physics it feels like it uh what was it rutherford that said like like basically that physics is the hard thing and everything is easy uh so like there's a certain sense once you've figured out some basic like physics that it's not that you need the tools of physics to understand the other disciplines it's that you're empowered by having done difficult shit i mean the ultimate i think is probably mathematics there yeah true uh so maybe just doing difficult things and proving to yourself that you can do difficult things whatever those are that's not positive i believe not positive yeah and i think like i i before i started a company i had like i worked in the financial sector for a bit and like i think having a physics background i was i felt i was not afraid of like learning like finance things and i think like when you come from those backgrounds you are generally not afraid of stepping into other fields and learning about those because um yeah i feel they've learned a lot of difficult things and um yeah that's an added benefit i believe this was an incredible conversation luis joao we started with uh who do we start with feynman ended up with messi and ronaldo so this is like the perfect conversation it's really an honor that you guys would waste all this time with me today it's it was really fun thanks thank you so much for having us yeah thank you so much thanks for listening to this conversation with louise and joe albertalla and thank you to skiff simply safe indeed netsuite and for sigmatic check them out in the description to support this podcast and now let me leave you with some words from richard feynman nobody ever figures out what life is all about and it doesn't matter explore the world nearly everything is really interesting if you go into it deeply enough thank you for listening i hope to see you next time you
