Important information regarding the recent AMS power outage.

The transformer that provides electricity to the AMS building in Providence went down on Sunday, April 22. The restoration of our email, website, AMS Bookstore and other systems is almost complete. We are currently running on a generator but overnight a new transformer should be hooked up and (fingers crossed) we should be fine by 8:00 (EDT) Wednesday morning. This issue has affected selected phones, which should be repaired by the end of today. No email was lost, although the accumulated messages are only just now being delivered so you should expect some delay.

Thanks for your patience.

George David Birkhoff


18. George David Birkhoff (1884-1944)

President, 1925-1926

Ph.D. University of Chicago, Illinois, 1907

After receiving his doctorate Birkhoff taught at the University of Wisconsin at Madison, at Princeton University, and then in 1912 at Harvard University, where he stayed the rest of his life. Through his trips to Europe and around the globe, Birkhoff made contacts with many scholars, and was in demand as a writer and speaker. His main research was in the fields of differential and difference equations, calculus of variations, relativity, dynamical systems and stability, the three-body problem, and Poincaré's geometric theorem. Birkhoff was awarded the first AMS Bôcher Memorial Prize in 1923 for his paper, "Dynamical systems with two degrees of freedom," Transactions of the AMS (Vol. 18, 1917, pp. 199-300), and the Society established the George David Birkhoff Prize in Applied Mathematics in 1967. Birkhoff was a member of the U.S. National Academy of Sciences.
