I've been enjoying the streaming video lectures available at www.msri.org. MSRI is the Mathematical Sciences Research Institute, which sits on a hill above UC Berkeley. MSRI is funded by NSF and other donors and has no apparent formal connection with UCB (that I can find). The streaming videos need RealPlayer, but a free version is readily available. The quality is only mediocre...the mathematicians are still using overhead transparencies with scrawled writing, and this doesn't pick up and show well, at least on my own RealPlayer setup. And I get the usual jerky video from my slow dial-up line, but at least the audio track is excellent. I haven't looked at the crypto lectures yet. Dan Bernstein has several of them, including on fast multiplication hardware for crypto. And the usual other mathematicians who do crypto are represented. (BTW, having such videos--hopefully with better quality than overhead projectors--might be an interesting option for the "Crypto for T.C. Mits" project some of you have been talking about. ) --Tim May "The great object is that every man be armed and everyone who is able may have a gun." --Patrick Henry "The best we can hope for concerning the people at large is that they be properly armed." --Alexander Hamilton
