Among the course webcast series being offered this term from UC Berkeley to all viewers/listeners is this jewel for librarians: Search Engines: Technology, Society and Business. Professor Marti Hearst of SIMS has managed to make such search luminaries as Sergey Brin, Hal Varian, Peter Norvig, and Mary Hodder available to her class and gotten their permission to video and record it for a future life as video- and pod-casts.
Other course offerings include intro classes in astronomy, biology, chemistry, computers, nutrition, anatomy, and physics, and, among others, a course in Buddhist psychology.
