These are an interesting few lectures given by Richard Feynman. This was after QED (quantum electrodynamics) was firmly established which explains light and the behavior of electrons. These lectures however were given before things like quarks and thus the proton were not fully understood which he also discusses a bit about.
For anyone who is confused about things like wave particle duality (they are particles!) and what the heck quantum mechanics really is should watch these lectures. Although Feynman makes it clear no one understands QM you will see what he means if you watch it. He doesn't use complex mathematics really in his lectures so its for a wider audience. The man is a genius.
Also its very refreshing to see someone who can teach so much with just a piece of chalk and a blackboard. Fuck powerpoint.
