À Orsay, une bibliothèque centrale pour les mathématiques 📚
La bibliothèque Jacques Hadamard ne se contente pas d’abriter des ouvrages : elle incarne un dispositif documentaire au service des mathématiques françaises.

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.”

The mathematician Anton Bernshteyn studies infinite networks of nodes and edges. Sometimes, he goes to computer science talks, where networks are finite. One of these talks led him to discover a bridge between the two fields, which he proved in 2023.
A New Bridge Links the Strange Math of Infinity to Computer Science | Quanta Magazine
Descriptive set theorists study the niche mathematics of infinity. Now, they’ve shown that their problems can be rewritten in the concrete language of algorithms.
