Minute Physics promises to bring you "cool physics and other sweet science - all in a minute!" In this case, they went a little longer and produced an animated video that gives you "The Origin of Quantum Mechanics" in four minutes. But cut them a little slack, it's a big subject.

He has also previously taught at Princeton and Cambridge. A second video featuring Turok -- "Real World Telekinesis" -- appears right below:
