For the last few years I've had the Feynman Lectures [1,2] sitting in my queue, and I've finally gotten around to starting them in the last week. It's been a fun ride so far, and it's been nice to have the time to digest the lessons without having to run off somewhere. It's also helped to have the MIT OCW lectures as a reference [3], in which I found a book title "Quantum Mechanics and Experience" [4] that I started reading as well and so far has been the most down-to-earth introduction to Quantum Mechanics that I've found. I highly recommend it.
I always thought Feynman's treatment of electrodynamics wasn't very original, that it was just the standard approach you could find in other textbooks. It turns out, Feynman thought so to, but later came up with a much better way of teaching electrodynamics: https://physics.stackexchange.com/questions/100951/what-was-...
