It's back: PBS is again providing late-night (around 2.30 am on WENH here near Boston) showings of several episodes of the famous, freshman-level CalTech physics course: "The Mechanical Universe." It very clearly explains topics spanning vectors, inertia, and special relativity, and was pioneering in its use of computer graphics for education (by Jim Blinn).
I mentioned this last year in the hopes that some of you would find it interesting.
You can try a few episodes by setting your DVR to record the upcoming episodes. TiVo just needs the program title for a "Season Pass."
I still have the special relativity episode from last year's reruns because it explains space-time and simultaneity so well.
