Yuo. Collier claims Robert Leighton wrote The Feynman Lectures on Physics, but all he did was edit Feynman's lectures in Volume I, as she (or you) could ascertain by listening to the lecture recordings and reading along with the text, both of which are available online (free) at The Feynman Lectures Website, https://www.feynmanlectures.caltech.edu. Collier completely fails to mention Matthew Sands who edited Volumes II and III. So Collier is full of it. And not only with regard to FLP. She claims, for example, that Feynman's stories in Surely You're Joking Mr. Feynman and What Do You Care What Other People Think are lies which is itself a lie (for which she offers no proof - because there is none) and that Ralph Leighton, who edited those books, by admiring Feynman as a physicist, was intentionally insulting his father Robert Leighton, which is complete bullsh*t, as I can tell you for a fact because I know them personally. Collier, in fact, defames Feynman and Leighton, not only in this video, but in others, and that is to attract views from ignoramuses, through hate-mongering. Let me mention also that Collier is just some poorly paid junior postdoc who makes money from her YouTube videos. And let me also mention that Feynman is greatly admired, as a physcist, a teacher, and as a human being, by millions of people, including many great physicists, physics teachers, and physics students. Finally, in closing I will mention that Feynman's books, including his autographical books (edited by Ralph Leighton) and The Feynman Lectures on Physics (edited by Robert Leighton and Matthew Sands) are best sellers, have been for a long time, and will continue to be, despite hate-mongering YouTubers like Collier, and the idiots who parrot them.
