The Feynman Lectures were a staple of my education, including having Feynman come to UC Irvine a speak to the Student Physics Society on his current work in Quantum Electrodynamics (QED).
The 3 volume set is still in our library. Mine are hardbound, there are paperbacks available now.
The books are not actually very good textbooks. The Lectures are just that, transcriptions of lectures. When reading them, you can hear Feynman talk, in the way several other authors write in the way they talk.
The point of this post is the Lectures are now available electronically at The Feynman Lectures on Physics.
For anyone interested in physics, or has ever heard of Richard Feynman should take a look.
My memory - after many decades - is Feynman loved students in ways not all physics professors do. He was a professional teacher as well as a physicist. His Nobel prize never got in the way of his love of students. One of our own Nobel Laureates, Fred Reines had a similar view of students - both undergrad and grad students. Dr. Reines would invite us to his house for BBQ and entertain us with stories of Los Alamos and other adventures.
Take a look, see how a true teacher writes about a topic he loves.
