Eric Weinstein's Theory of Everything "Geometric Unity" Explained

Video Description

Eric Weinstein's framework for a unified theory of everything in physics... I've been working on this project assiduously and secretly since last year. It's been several months in the making, with several rewrites and several re-edits. It's finally ready to be released, thus shadow dropping it now. It's a 3-hour iceberg on Eric Weinstein's Geometric Unity. I work on understanding and explaining different Theories of Everything for a living, and this one is unlike any other you've seen. This iceberg covers the graduate-level math, but it also constantly provides explainers aimed at different levels for those who are uninitiated with physics and differential geometry. Enjoy.
