On Khovanov's categorification of the Jones polynomial — mentioned by throw_away_8080

I want to clarify, I am not trivializing the work of category theorist. It is a field of mathematics which provides a useful framework for algebraic geometers and algebraic topologists, and has even been fruitfully applied outside of math. A personal favorite of CT generalizing an existing idea is in knot theory the khovanov homology detects the unknot, which is an amazing feat for a knot invariant. Bar Natan covers the construction well: https://arxiv.org/abs/math/0201043 However for some reason this particular field of math is a lightning rod for quacks. I don't really know why, but that is…

Courses would benefit from "quick-reference guides like the end of Dror Bar Natan's paper on Khovanov homology http://arxiv.org/abs/math/0201043 He says "It can fit inside your wallet." See: http://www.math.toronto.edu/drorbn/Talks/HUJI-011104/cube.gi...
