Brian Cox's Guide to Quantum Mechanics

Ok, so last time we talked about the properties of light on this blog, in the Light Fantastic documentary series, we saw Thomas Young was able to account for color by arguing that light must be some sort of wave: different frequencies would produce different colors.

Well, given its strange history, it should come as no surprise to you by now that light would conceal even more mysteries. In the following short clip, Brian Cox explains Einstein's photoelectric effect and his challenge to the wave theory of light, all of which opens the door for an explanation of one of Richard Feynman's greatest contributions to physics: quantum electrodynamics, as well as the justification for building the Large Hadron Collider.



Of course, if Brian Cox isn't your cup of tea, you can also hear a description of QED from Feynman himself in this classic jewel.
