### Foundations of Math and Physics One Century After Hilbert

#### Posted by John Baez

I wrote a review of this book with chapters by Penrose, Witten, Connes, Atiyah, Smolin and others:

- John Baez, review of
*Foundations of Mathematics and Physics One Century After Hilbert: New Perspectives*, edited by Joseph Kouneiher,*Notices of the American Mathematical Society***66**no. 11 (November 2019), 1690–1692.

It gave me a chance to say a bit—just a tiny bit—about the current state of fundamental physics and the foundations of mathematics.

It might have been an interesting experiment to mix it up and have the contributors write about each other’s projects: Connes on twistors, Penrose on noncommutative geometry, etc.

I’m surprised the claim about the 6-sphere got through. That’s pretty far out of my wheelhouse, and even I’d heard that Atiyah’s proof has not been generally accepted.
