Its Volume III (quantum mechanics) that really changed physics education, imho. It dispensed with a long tradition of continuous PDE's (Schrödinger equation) based approaches (which needlessly obscured the essence of quantum behavior) and brought to the fore discrete systems (like spin) and the beautiful Dirac notation (so he, too, stood on giant's shoulders). Feynman really is the grand-master of KISS and the nemesis of obfuscation. We should all be a little bit like Feynman.
