This reminds me of John Nash's letter where he declined an offer for a prestigious chair at the University of Chicago because he was expecting to become Emperor of Antarctica.

I recently read "Mathematica" by David Bessis, and I think it's a fantastic book! Before I recommend it to everyone, I would love to hear from people who do mathematics, or at least prove a theorem now and then. Do you agree with Bessis' description of what mathematics is and what mathematicians do?

In case you are still trying to find a present for yourself or a loved one who would like to hear more about what we mathematicians do and how so.... I can only recommend Bessis' book Mathematica. What a wonderful read. I could highlight every other sentence.

Taken at face value, "twins reared apart" studies seem to prove the IQ is almost entirely genetic. But when you look at the actual science, you realize that it is entirely inconclusive — the approach just doen't work!

His book "Mathematica" is a real eye-opener. David Bessis describes accurately and vividly the way we perceive and manipulate mathematical objects. Colleagues who read it also felt he put into words what they had not been able to formulate about the mathematical process. Highly recommended.

Just received this legitimate reader request: could I publish a French Substack, alongside the original English? (The same could be asked about my posts here.) I could, but it wouldn't be worth the effort. I'm writing for a global audience whose only lingua franca is English.

Russ Roberts’ “Econ Talk” is one of the most interesting podcasts.

This episode with @davidbessis.bsky.social is truly fascinating.

It got me thinking we should train students to think of research as “a dialogue between intuition and evidence.”

Turing's high school teacher (from B. Jack Copeland's biography of Turing). More evidence for @davidbessis.bsky.social's hypothesis: great mathematicians got great by continuously reconstructing everything they were taught, for themselves. This is why Turing invented "the Turing machine" at age 23.

Having fought and overcome the twin demons of anxiety and depression, there is nothing any fascist could do to scare me.
10. This is the reality of being an academic in the United States today.

But Vought and Rufo are missing something.

We aren't cowards.

And we know we are not the enemies of the American people either, much as these ideologues might like to claim that.
