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.
"Computers, Paradoxes and the Foundations of Mathematics," by Gregory J. Chaitin. American Scientist, March-April 2002, pages 164-171.
Chaitin's article is excerpted from a 1999 lecture that he delivered at the University of Massachusetts, Lowell. He traces the history of formalism and incompleteness, concluding with randomness and algorithmic information theory. A nice feature of the article is illustrations of Bertrand Russell, David Hilbert, Kurt Gödel and Alan Turing, which accompany descriptions of their contributions to the subject.
