Sean Carroll’s Biggest Ideas in the Universe YouTube series is fantastic. Just enough math to be interesting but nothing requiring a math degree. [VIDEO]

The Biggest Ideas in the Universe by Sean Carroll, an intro to modern physics, including homotopy and quantum field theory. He does some math but you'll follow if you've finished high school. Don't miss the Q&A videos in between the 26 regular episodes. [VIDEO]
