I took part to the Chantiers Arts, Technologies et Sciences, with researcher Bertrand Michel, theatre writers Sylvain Renard and Rémi Chechetto, and technical high school classes and teachers. The project should originally have happened in 2020, but due to the Covid pandemic it has been extended, and eventually lasted for three full years.

Sylvain and I have been writing on this experience since, hopefully it will be eventually published…

I really like to tell the story of the four colors theorem. I did it multiple times, with various durations (from 5 min to 1h30) and publics (students, researchers, "amateurs"). I was mostly using a board, so no traces remain, but one on those instances was filmed as part of the 5 minutes Lebesgue.

A one-hour talk titled How we can classify things we know nothing about, using a little bit of computability theory, as part of the Séminaire de la Détente Mathématique.
