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.

"Why Some Numbers Are Only Very Good Guesses," by Gina Kolata.  NewYork Times, 11 March 2001.

This brief article discusses why some data simply cannot be made moreaccurate. One example offered is the 2000 census, which is known to havemissed about 3.3 million people.  The Census Bureau had to decidewhether to use statistical sampling to help adjust the count .  Anexpert panel advised against doing so, because statistical sampling introducesits own biases and errors.  Historian Edward Tenner says such quandriesusually arise when people try to change how a number is formulated. Kolata writes: "The trick, he said, is either to learn to live with knowninaccuracies or to be sure that any new number is really an improvement."
