Jim Gates: What is Supersymmetry? | AI Podcast Clips

Lex Fridman

Jim Gates introduces supersymmetry using a visual analogy of a pie divided into four quadrants to represent particles in our universe. In this model, one quadrant contains matter particles like electrons and quarks (often described as "corks"), while another holds force carriers such as photons that pass through each other without interacting. The remaining two quadrants are initially empty because the known forces do not interact with matter in a way that suggests symmetry between them.…
