Even though EXPLO.TV sounds like an edgy punk website, it's actually the video component of the Exploratorium: Museum of Science, Art and Human Perception in San Francisco. This website has some excellent ways to learn about science--such as webcasts, podcasts, and video clips. "Upcoming Webcasts" is featured on the homepage, and there are a number of fine webcasts here. Because the webcasts are produced in San Francisco, people who live in the area can go to the live audio or video broadcast. They just need to click on the link "Attend the Live Event" to learn how. Visitors can also subscribe to a monthly e-newsletter that keeps them updated on the happenings and special events at the Exploratorium.
