The Feynman Lectures on Physics: Algebra (1963)
This specific Feynmann Lecture popped up very recently either here or on lobste.rs. I have since bookmarked the "FLP" series as I really want to come back to it, but I'm curious if there is any significance to why the Algebra lecture in particular was submitted a couple of times. Is it just coincidence, or was it a particularly good one?
