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.

"The Tornado in the Shower," R&D News section, Discover, October 2001.

David Schmidt (University of Massachusetts) wanted to find out why theshower curtain billows inward when you turn on the water. He used asoftware package to create a virtual shower and after 1.5 trillioncalculations thinks he has found the answer. Drops of water from theshowerhead decelerate due to aerodynamic drag, and the slowdown pulls theair around the droplets into a tornado-like vortex, which creates alow-pressure center that can suck in a lightweight curtain.
