On the new site Academic Earth you can watch lectures on physics from M.I.T., or catch a Yale history course on the origins of World War I, or see a U.C. Berkeley professor cradle a brain while she talks about human anatomy.
Backed by angel funding, Academic Earth aims to bring videotaped university courses and lectures to a wide audience.
