To nobody's surprise, universities are increasingly putting some effort into putting high-quality course lectures on the Web. (Where this ultimately will lead isn't completely clear.) We've already mentioned Leonard Susskind's lectures on GR at Stanford. Now from Harvard, we have a course on Justice by Michael Sandel. (Via Julian Sanchez.) They really went all-out on the production values, teaming with the local public TV station WGBH; this looks a lot better than what you would get from someone in the middle of the room with a hand-held camera. The lectures were held in Harvard's Sanders Theater, which is quite a beautiful space. You get something of an idea what it's like to be a Harvard undergrad; there are a lot of students in the class. Most professors don't wear suits and ties, however.
