I am studying to return to school in physics and would like to start spending as much time as possible on that task. Most of my small amount of free time, however, I am either doing house work or commuting to work. While it is difficult or impossible to read while doing these chores, I think I could get great benefit out of listening to educational physics material. I know that there are textbook reading services for the blind, but I have not been able to locate audio versions of physics texts available to the public. I know that several schools put their lecture material on YouTube, but I would love to get something that is specifically oriented to an audio only audience.
Are there any good resources to find educational material on physics in the form of audio?
