How Mathematical Proofs Are Like Recipes

TL;DR
Mathematical proof explained as recipes with picture proofs challenging traditional assertions.
Transcript
(audience applauds) - Hello, I am also going to be thinking about the question of what a mathematical proof is today, but I'm interested in modern proofs, and modern mathematics as you find it nowadays. Mathematical proof, now, is still a central pillar of the methodology of pure mathematics, it contains a lot of the techniques, and the ideas, and ... Read More
