Saturday Morning Physics is featured on the new iTunes U. You can access iTunes U through the Apple Music Store (select "University of Michigan" from the list of participating universities) or the U-M launch page:

This collection offers video and audio selections from units around campus, and it has unlimited capacity for growth, with potential to feature some of U-M's best public lectures and activities.
The University is collecting more content each day, so this site will grow. I will submit Ta-You Wu and Ford lectures to the mix.

Physics Professor Brad Orr's Saturday Morning Physics lecture is the top downloaded talk on iTunes U.  

You can read more about iTunes U in an upcoming University Record article.
