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.

"Chaos in Space and Time," by J. P. Gollub and M. C. Cross. Nature, 13 April 2000, pages 710-711.

Although chaotic dynamics arise in many natural phenomena, scientists' understanding of chaos in most systems is limited. This article describes new numerical studies of a model of thermal convection. These studies reveal for the first time the mechanism by which chaotic dynamics is generated. The work shows that the unpredictable motion that arises in this model has its origin in what happens in small regions of space and over short time scales. "Applications to areas as diverse as cardiology and atmospheric dynamics might be expected eventually," the article says.
