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.

"Profile: T. V. Raman. Envisioning Speech," by W. Wayt Gibbs. Scientific American, September 1996, pages 52-54.
These two articles discuss the challenge of building computer devices that convert text to speech when the text contains mathematical expressions. T. V. Raman, a blind mathematician and computer scientist who now works for Adobe Systems, formulated such a device in his doctoral dissertation in 1994. He has constructed a high-level programming language that controls the way mathematical expressions are spoken by a computer voice synthesizer.
