Found this on the Bautforum, Prof. Richard Pogge of Ohio State has put audio files of his lectures for "Introduction to Stars, Galaxies, & the Universe" at:
Theres quite a few... I've got ones from Berkley State University, Also got their full Astrophysics course, every lecture of every unit on my mobile phone.. I listen to them all day at work.. Some of it goes over my head but I keep up mostly.. Reference certain material that helps me understand the bits I don't get upon the first listen etc.. .Definitely worth while..
Agree.
This new course should be interesting.
I see that he has a lecture titled "The Copernican Revolution". Astronomy 161 missed half this topic due to tech problems.
