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.
"Bend and survive," by Victor Steinberg. Nature, 5 December 2002.
"The aim of aerodynamic design is to reduce the drag experienced by a body,such as a car, in a flowing medium, such as air. But what happens if the bodyis flexible and bends in response to the flow?" Steinberg summarizes "Dragreduction through self-similar bending of a flexible body," by Silas Alben,Michael Shelley and Jun Zhang, published in issue. The researchers'mathematical model couples hydrodynamics and the effects of bending and showsthat "the key to drag reduction is the creation of a 'self-similar' shape." TheNew York Times and the Boston Globe both reported on thefindings.
