So good to see liberal America standing up to the Trumpian threat today. A strange thing happened to me as I followed the topical posts.

Each time I saw the #HandsOff hashtag, what my brain read instead was #Hausdorff, for Felix Hausdorff, the eminent mathematician.

To my shame, I knew nothing about Felix Hausdorff the man. To me as a former Berliner and an emigree to England, Hausdorff sounded like an East Prussian landed-gentry name, I expected a Junker. Wrong. Today I learnt that Felix Hausdorff was in fact Jewish. He, his wife and his sister in law escaped the death camps by suicide, in 1942. (His daughter Lenore survived.) I never knew.

So there really is a hidden connection between today's encouraging #HandsOff news and Felix Hausdorff, the great thinker who was exposed to the same evil of unchecked state power that threatens us today, and against which today's protests took a stance.

Happy birthday to one of greatest #mathematicians of all time Emmy Noether (1882-1935), here with her eponymous theorem, the backbone of modern physics. Noether’s theorem links any symmetry of a system with a conservation law. In my portrait, I chose to depict a young Emmy in front of a blackboard with a more simple formulation of her theorem and three specific applications of it, shown schematically, 1/

Happy birthday #DonaldKnuth!

Mathematicians denounce Israel’s genocide in Gaza
1/2
More than 1,000 mathematicians have signed an open letter calling on their colleagues to “cease all scientific collaboration with Israeli institutions that do not explicitly condemn the genocide in Gaza and the illegal colonisation of Palestine”.

You can read their letter in full here.

❛❛ Teen #Mathematicians Tie #Knots Through a #Mind-Blowing Fractal ❜❜

Three high schoolers and their mentor revisited a century-old #theorem to prove that all #knots can be found in a #fractal called the #MengerSponge.

Fellow #Programmers, #Coders (and possibly #Mathematicians) lend me your wisdom!

I’m learning from books and I “know” the best way to learn from them is to work through them. But what I don’t know is how I’m doing. I’m often frustrated at my pace, since I don’t know what normal is.

And I need to learn stuff, to land a job. (I’m old. I want to pivot into a remote job, ergo devops. Anyway, that’s enough about me.)

So here’s the question(s),

1. How long do you take to work through a new text / proof / new book on a new topic that you don't know?

2. How long did it take you (if you remember) when you were just starting out?
3. Were you doing this on your own?
4. Were there other people / things / places that aided you?

Please boost, to help a slow learner?! Thank you!

Thoughtful and moving piece about the later life of the great mathematician Alexander Grothendieck.

A complex and troubled life, empathetically and intelligently reconstructed by writer Phil Hoad. We meet Grothendieck's family and fellow mathematiciens. Deeply insightful.

I usually enjoy the "long read" articles you sometimes find in the weekend papers. This is Long Read at its best.

I need a word for that amazing feeling you get when two #mathematicians who were your postdocs marry and have a baby…

What is it that stops #mathematicians from speaking up about things they'd like to work on?
