this is an awesome video. Funny thing is I think I was subconciously taught how to do vectors by Richard Feynman in his book QED, which explains light, electrons, and other interactions of quantumelectrodynamics. He uses a method of attatching arrows which represent amplitudes. The final arrow connects the first and last arrow and the square of this arrow is the probability of an event happening. I didn't even realize that this method was using vectors! Tricky Mr. Feynman.
