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.
"The Logic of Human Learning," by Nick Chater, and "Minimization of BooleanComplexity in Human Concept Learning," by Jacob Feldman. Nature, 5October 2000.
Jacob Feldman, of Rutger's University's Center for Cognitive Science, presentsevidence that how difficult a concept is to learn can be measured by theshortest Boolean string required to express that concept. Feldman's work fitswell with the idea of Kolmogorov complexity, which measures the complexity of aconcept by the the length of the shortest computer program that could generateit.
