You appear to be parroting the nonsense from Collier's "I hate Feynman" videos. Feynman gave the FLP lectures at Caltech, which were recorded and photographed, but at that time the…

Let me begin by saying that I am a friend of Ralph Leighton, whom I have known for 27 years. I am also a friend of Feynman's children, and several of Feynman's friends and colleagu…

Yang died very recently. He was 103 years old.

I don't know what "notes" you are referring to, but if you mean the chapters of The Feynman Lectures on Physics, the recordings and photos of Feynman's 2-year Caltech course on Int…

Hello _wire_. I tried to find the "quotations" you have attributed to The Feynman Lectures on Physics. I looked in Volume I chapters 37 and 38 (which are the same as Volume III cha…

Anyone who could write this has apparently no familiarity with The Feynman Lectures on Physics, which is chock full of quite difficult mathematics.

Feynman's introductory physics course also entailed a lot of problem-solving and labs, in addition to the lectures that are the basis for The Feynman Lectures on Physics. If you go…

You have to bear in mind that the lectures in The Feynman Lectures on Physics were only one third of an introductory physics course, the other parts being recitation sections (in w…

The Feynman Lectures on Physics was used as the textbook for Caltech's introductory physics course for nearly two decades, and it is still used in some universities. I learned phys…

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 t…

Angela Collier, who made that video, if full of it.

Thanks for buying my book. You're very welcome for the website. I don't know specifically to what plot Feynman was referring, but it may have been one he made himself.

At the time my colleagues and I proposed creating an online edition of FLP, one could only read it in expensive printed editions or in (lousy-looking) pirated PDFs. It was not easy…

The "2013" is the copyright date of the initial publication of the online edition of The Feynman Lectures on Physics, but that edition (as well as the printed edition) and the Feyn…

The lecture recordings were added to The Feynman Lectures Website in 2021. It was not easy to convince the publisher (Basic Books) who licenses the exclusive publication rights for…

The original Feynman Lectures Website was feynmanlectures.info, which went online in 2006. The online edition of The Feynman Lectures on Physics was published there in 2013, and al…

We are currently working on a 'reconstruction' of the first lecture recording, which we hope to publish at The Feynman Lectures Website later this year.

The FLP lecture recordings posted at The Feynman Lectures website are "archival" recordings derived from the original 1/4" reel-to-reel tapes, which were digitized at high-resoluti…

If you folks have any questions about the Feynman Lectures Website, the online edition of The Feynman Lectures on Physics, the current ("New Millennium") printed edition (or ePub o…

The introductory physics course for which Feynman lectured in 1961-63 is part of Caltech's core curriculum, required of all undergraduate students. It was taken by the entire fresh…

Thank you, packetslave!

I am working on the conversion of Volume II from LaTeX to HTML. There are 8 chapters left to go. When they are done, and after I have spent some time testing and debugging Volume I…

For a similar, but more complete, description (with figures), see "Feynman's Tips on Physics," Section 4-10, The Spinning Disk, and "The Feynman Lectures on Physics," Volume I, Sec…
