As we noted last year, the Annenberg/CPB college television course series, The Mechanical Universe, had to be removed from Annenberg's video on demand website. At the time, it seemed the series was being banished to oblivion for fear of the expiration of media rights to included (non-original) video [I'm guessing the Kepler-related footage].
In any case, it seems that CalTech has posted the series to YouTube. Start at the link below.

That's good news for those of us who continue to find the series to be a rich instructional resource. Especially those who like to flip a good video lesson from time to time.
Here's CalTech's announcement on the matter.
