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.

"What is the best way to lace your shoes?," by Burkhard Polster. Nature, 5 December 2002.

The results of this research paper were picked up by Reuters and reported in The New York Times and Boston Globe newspapers. Essentially, Polster found that although most of us lace shoes using the "criss-cross" or "straight" method, the most efficient way to tie shoelaces (in order to use the least amount of lace) is the "bow-tie" method. The article includes diagrams and the mathematical explanation.
