Despite the “2” in the title, you can follow this post without having read part 1. The whole point is to sneak up on the metricky, analysisy stuff about potential functions from a categorical angle, ...

Cauchy distributions form a convolution semigroup, i.e. μt + s = μt * μs. This is because to hit a plane at distance t + s the Brownian motion has to hit a parallel plane at distance t first, and then ...

Applied category theorists are flocking to AI, because that’s where the money is. I avoid working on it, both because I have an instinctive dislike of ‘hot topics’, and because at present AI is mainly ...
