I don't know how many of you remember watching the video series "The Mechanical Universe...and Beyond" as physics undergrads. But my professors used this on occasion, and I found their illustrations to be extremely helpful in understanding certain principles in physics. And the historical perspective they gave was rather interesting too. Anyway, I found the whole series online, and you can watch it for free here: http://www.learner.org/resources/series42.html# So yeah, if any of you guys know undergrads, perhaps you could point them this way. Or if any of you are undergrads, you might find this interesting.
