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 J…

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-…

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 …

Yes! Draw an equilateral triangle with side length one. Then cut it in half and reason from there.

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.yo…

Nice! I like the way you put this.

_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…

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 serio…

I don’t think most PhD physicists know what a diffeomorphism is.

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…

Worth noting that all the results discussed in this article are 20+ years old. Bored reporter?

At Tachyus ( http://tachyus.com ) we have made a huge bet on F#, and it has paid off in spades. The back end of our SaaS product is 99%+ F#, and so far we have had a great experien…

At Tachyus (tachyus.com), we are using 100% F# to build the back end of our platform. Getting from zero to our first product deployment in three months, we've proven that F# is a g…

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