There clearly is a wonderful story hiding in here.

## Foundations of Mathematics

February 1, 2019**Foundations of Mathematics**, Andrés E. Caicedo, James Cummings, Peter Koellner, and Paul B. Larson, eds., Contemporary Mathematics, vol. 690, Amer. Math. Soc., Providence, RI, 2017. DOI: 10.1090/conm/690. MR3656304. Zbl 06733965.

This book contains the proceedings of the conference in honor of Hugh Woodin’s 60th birthday, that I previously discussed on this blog (here, here, and here).

The AMS page for the volume can be found here, including the table of contents and links to the front- and endmatter (which I think are available to everybody) and links to the individual papers (which I imagine may not be).

## A puzzle

January 18, 2019## Special Session

October 22, 2018Two pictures from last weekend’s Session.

We rescued this one from Instagram a couple of minutes after it happened (Paul noticed that #determinacy was missing from the list):

And a decent group picture. Missing: Maryanthe Malliaris (who took it), Harry Altman and Jeffrey Bergfalk:

Many thanks to all the participants, and to the AMS for making it possible.
