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.
The mathematician David Bessis believes that mathematical skill is not innate, but learned. “Genius is not an essence. It’s a state. It’s a state that you build by doing a certain job.”

Wait ! That's me !
And now Florian Ingels present multiminimizers and various results about density at #Seqbim
Once again thread (I'm pretty late) incoming and for those you absolutely can't wait the preprint is already out if you want to spoil yourself :p

Hi, I am a mathematician in a movie. I have written some non-sense equations on my (black)-board, will use fancy terms that are supposed to make me look smart, and will probably serve as a caution that whatever magical thingy happens in the movie is actually science.
Hi, I’m an highschool teacher in a movie. I start my class with a random question on a topic I’ve never discussed before so the new girl can show off. Then if I say something relevant about the main conflict, the bell rang and the students leave even if the class started 5 minutes ago.
Hi, I'm a publicist in a movie. You'll see me in a meeting presenting some passé bullshit to a cadre of executives who will be impressed but have one little remark. I spend a lot of time in my office even if it's not really clear what I actually do. Chances are? I'm also a huge misogynist.

I do not recommend staying up late until 3 a.m. because your brain can't accept that you can postpone solving that one collegue's problem he sent you via email during the evening and that you read around midnight
but it's solved!
