Bon le #vendredilecture qui se termine le #samedilecture parle de #Grothendieck
C’est une biographie rapide, un peu brouillonne, un peu désordonnée mais qui donne à lire une introduction à la vie d’un des plus grands mathématiciens d’après guerre qui a réussi, en compagnie de ses complices du groupe #bourbaki , le tour de force de faire détester la #mathématique à un nombre impressionnant d’élèves (mais ca ne parle pas de cette magnifique réussite de sélection des esprits les plus étroits et privilégiés que notre pays doit aux #mathmodernes)

On the theorem of Gelfand–Mazur. New blog post on Freedom Math Dance

I discuss several elementary proofs of this theorem that I learned by browsing at the online Bourbaki archives. They are due to Tornheim and Witt.

On the theorem of Gelfand-Mazur

In its classical statement, the theorem of Gelfand-Mazur is the following: Theorem 1 . — Let $K$ be a complete normed field which is an ext...

Ah, the *super-secret* cabal of number wizards, Bourbaki! 🤔 Instead of arcane rituals, they spend their days lost in the Google Books labyrinth, probably searching for the mystical "Book of Relevance." 📚🔍 Clearly, covert mathematicians can't escape the allure of aimless internet browsing. 😂

Mathematics: the key is to go beyond the specific formula and look for the underlying structure. Good proofs allow us to by-pass the complex formulas from the special case.

Working hard to end up with elegant laziness.

That's my humble take on how to do maths, as a jobbing quantitative social scientist.

Exactly 90 years ago, on December 10th 1934, Weil, Delsarte, Cartan, Dieudonne, de Possel and Chevalley got together in 'A Capoulade' for the first (proto) #Bourbaki meeting.
