BB(5) talk at Collège de France
October 27th 2025
I was invited by Prof. Timothy Gowers to present BB(5) at the Collège de France, as part of his seminar series on The Philosophy of Mathematical Practice. It was great honour and pleasure to give this talk. The talk (in French, sorry!! but YouTube subtitles are not too bad) is rather non-technical and presents to the general public what the Busy Beaver problem is and how we collaboratively solved BB(5) at https://bbchallenge.org/.
The slides of this talk are available here.
