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.

"Stats say aye to ID eye," by Helen Pearson. Nature Science Update, August 8, 2001.

The subject of this cleverly titled article is iris recognition, a technique for identifying oneself by the pattern of the iris. Iris recognition is scheduled to be tested soon at London's Heathrow airport and is envisioned for use at ATMs. Analysis done recently by John Daugman and Cathryn Downing of the University of Cambridge shows that the likelihood of an error when using iris recognition is about one in seven billion. Daugman and Downing's research is published in the article "Epigenetic randomness, complexity and singularity of human iris patterns" in Proceedings of the Royal Society B, Vol. 468.
