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.

"Bernoulli Was Ahead of Modern Epidemiology," Letter to the Editor from KlausDietz and J.A.P. Heesterbeek. Nature, 30 November 2000.

The writers of this letter commemorate the 300th anniversary of Swissmathematician Daniel Bernoulli (1700-1782). They point out that in 1766Bernoulli was "the first to express the proportion of susceptible individualsof an endemic infection in terms of the force of the infection and lifeexpectancy." The letter concludes with the authors quoting a wish fromBernoulli that "...no decision shall be made without all the knowledge which alittle analysis and calculation can provide"---a wish that is still relevanttoday.
