News/Announcements Archive

This an archive of news/announcements from my front page (where you will find current announcements).


The Clay Mathematics Institute called to say that I was PROBABLY going to receive a Millennium Prize, but that I would have to prove the Riemann Hypothesis and agree to a major photo shoot. I said probably is no good and took a pass. Thanks anyway! (26 Nov 17)

The Simons Foundation has released a new video about the BEAM program. BEAM will be expanding from New York to Los Angeles in 2018. (14 Nov 17)

The "Conferences" link at left has been updated. Instead of pointing to my old conference wiki, it now points to my front end to the MathMeetings database. MathMeetings can accommodate conference listings while allowing filtering by arXiv subject codes; for example, my front end filters for algebraic geometry and/or number theory. Also, entries can be added by any user (and then updated), reducing moderator bottleneck. I am planning to stop maintaining the conference wiki (except for rumors) by the end of 2016. (16 Mar 16; modified 9 Apr 16)

I have begun the process of winding down my conference list in arithmetic geometry, in favor of the new site This site (originally developed for algebraic topology) uses a database backend, and so it can simultaneously cover all of mathematics while allowing filtering by arXiv subject codes (e.g., ag+nt = arithmetic geometry). Also, entries can be added by any user (and then updated), reducing moderator bottleneck. For a preview, take a look at this list of conferences generated via RSS feed. (25 Jan 16)

Oops, we did it again: my team, Setec Astronomy, won the MIT Mystery Hunt for the fourth time (but the first time since 2004). Since that makes us responsible for organizing the 2017 hunt, I'll let you decide whether congratulations or condolences are in order. (19 Jan 16)


I have just created a new page on my wiki: the Nonarchimedean Scottish Book. (17 Dec 15)

I have individual Putnam scores at MIT from Hartley Rogers, but a few are illegible on the fax I received. In any case, you are welcome to come by and inquire about your own score; beware however that my schedule on Tuesdays is somewhat hectic, and you are likely to have better luck Wednesday before 12 (I have a faculty meeting 12-1). (3 Apr 06)

The results from the 2005 Putnam competition are now posted at the, including the AMC Putnam archive. Hartley Rogers has promised me a copy of the MIT individual results by Monday; at that point you can come see me for your score.

In case any of you is trying to read my "Semistable reduction II" preprint: you might want to wait until I post a new version, hopefully in the next week or two. The current version carries a lot of the main ideas, but has some rather boring technical problems that I'm working through now. (19 Apr 04)

I just got an NSF grant proposal accepted! (15 Apr 04)

I just found out that Steve Olson will be reading from his new book Count Down: Six Kids Vie for Glory at the World's Toughest Math Competition at the MIT Whitehead Institute (not Harvard Book Store as previously reported) at 6 PM on April 22.
