"physics and math music" I wasn't sure where to post this but here's the question. I have to take a 2 hour bus ride about once a week at night. since i can't really read then i thought that it'd be cool if i could get some lectures or something in a mp3, wma, wav... format. Does anyone know of audio media on the internet that teaches physics or math? (without needing any visuals such as blackboards)? Thanks.
