Who is funding this? Sounds like a fun experiment but that’s a huge amount of compute if I understand correctly.

I am a knot theorist (PhD student) and always tickled when the subject pops up on HN. Curious what the author had in mind including this in his algebraic topology notes. Even the Jones polynomial which is both algebra and topology is not

Well, all these closed surfaces you mention are (topologically) spheres. The theorem doesn’t apply to some other closed surfaces, like the torus, which does admit a continuous non-vanishing vector field.

Heard a mathematician friend call this the “hairy sphere theorem” once. At first I thought he was being a prude, but now I appreciate that the theorem is about spheres, as opposed to balls.

Yes! I’m working on this in my PhD research. Here’s a relevant Caltech lecture aimed at a general scientific audience, discussing use of ML to detect equivalent knots. https://m.youtube.com/watch?v=etNErJ1iuno

_Algebraic Topology_ by Allen Hatcher. This is quite an advanced book, but it was the first topology book I picked up and it blew my mind. Without a serious math background you may only be able to read the first parts (some of chapters 0

After I understood monads, I didn't write a short blog post about how simple they are. In fact, I took the opposite approach and am writing a ~500 page book about them :). In seriousness, there's a lot that goes into appreciating

For anyone curious, a Lie group is a continuous collection of symmetries. While a square, for example, has 8 symmetries (identity, three rotations, and 4 reflections), a circle has infinitely many: you can reflect it about any axis and rot

At Amazon or Microsoft you can pull down a $120K compensation package your first year and Seattle is (relatively) cheap.
