Feynman Lectures on Physics Vol. 1 Released in HTML Format

Dr. Richard Feynman's lectures on physics have been iconic standards of physics education for the past five decades. Videos of the series were put online at Microsoft Research a few years ago, but now the entirety of Volume 1 is available over simple HTML (mirror). In a letter to members of the Feynman Lectures Forum, editor Mike Gottlieb said, "It was an idea conceived many years ago, when through FL website correspondence I became aware of the many eager young minds who could benefit from reading FLP, who want to read it, but for economic or other reasons have no access to it, while at the same time I was becoming aware of the growing popularity of horrid scanned copies of old editions of FLP circulating on file-sharing and torrent websites. A free high-quality online edition was my proposed solution to both problems. All concerned agreed on the potential pedagogical benefits, but also had to be convinced that book sales would not be harmed. The conversion from LaTeX to HTML was expensive: we raised considerable funds, but ran out before finishing Volumes II and III, so we are only posting Volume I initially. (I am working on finishing Volumes II and III myself, as time permits, and will start posting chapters in the not-too-distant future, if all goes as planned.)"

Einstein presented E=mc^2 in a followup letter to his paper "On the Electrodynamics of Moving Bodies" (i.e. it's an interesting derivation, not an essential part of the theory).

    What about Poincare?

    Einstein's first paper on relativity was published three months after Poincare's short paper, but before Poincare's longer version. Einstein relied on the principle of relativity to derive the Lorentz transformations and used a similar clock synchronisation procedure (Einstein synchronisation) to the one that Poincare (1900) had described, but Einstein's was remarkable in that it contained no references at all. Poincare never acknowledged Einstein's work on special relativity. Einstein acknowledged Poincare posthumously in the text of a lecture in 1921 called Geometrie und Erfahrung in connection with non-Euclidean geometry, but not in connection with special relativity. A few years before his death, Einstein commented on Poincare as being one of the pioneers of relativity, saying "Lorentz had already recognised that the transformation named after him is essential for the analysis of Maxwell's equations, and Poincare deepened this insight still further ...."

    No. Not over-rated. He was capable of communicating ideas, deep and otherwise, clearly, which is very difficult. Consider how to convey the difference in magnitude between gravity and the electromagnetic force. The example he gives goes something like this:

    RF: What is your charge right now?

    Student: neutral.

    RF: Why?

    Student: Because we have the same amount of positive and negative charge.

    RF: OK. What would happen if you took some electrons from your neighbour?

    Student: I would become positive and he would be negative

    RF: Yes. Now I want you to imagine you steal some of the electrons from your neighbor. Let's not be greedy. Let's say you take 10% of them. Now you are negative and your friend is positive and you will feel an attractive force towards him. The question is: how strong is the force of attraction. Is it larger or smaller than the weight of the Empire State Building?

    Student: Hmmmm...dunno. I'm gonna guess larger.

    RF: Yes it is larger. But how much larger. Is the force of attraction between you and your neighbor larger or smaller than the weight of Mount Everest?

    Student: I'm gonna go with larger.

    RF: Yes, you are correct. In fact, the force of attaction between you and your neighbor WILL BE ABOUT THE SAME AS THE WEIGHT OF THE ENTIRE EARTH!

    The above paraphrased lesson emphasizes like nothing I've ever heard before how weak gravity is and how strong the electromagnetic force is. Simply brilliant.

    Hi. I teach undergraduate physics. If you're a clever high school or early college student interested in physics, you may have heard of Feynman, and you may have heard physics people give rave reviews of the Feynman lectures. And hey, he intended these lectures as a first-year college physics course, so that's perfect for you, right?

    Wrong. This is not the right place to start learning physics. Feynman has some beautiful insights about how introductory physics concepts connect to "real" modern physics, and a way of cutting through the red tape to elegantly explain concepts in ways that make experienced physicists drool. But that's not what you need. You need the red tape. You need to learn to apply concepts to real situations, you need to get buried in the algebra, trig and calculus and dig your way back out again. Feynman won't help you about that.

    Feynman's Lectures on Physics represent how an experienced modern physicist would teach introductory physics to a roomful of other professional physicists. Feynman was a genius, but his lectures are designed to impress, not to teach. You should absolutely read it, and you will love it, later in your career. But start with a more traditional textbook.

      You are correct that Feynman's books are insufficient to learn introductory physics, but the lectures were only one part of the curriculum. From Feynman's Preface:

      "The lectures form only part of the complete course. The whole group of 180 students gathered in a big lecture room twice a week to hear these lectures and then broke up into small groups of 15 to 20 students in recitation sections under the guidance of a teaching assistance. In addition, there was a laboratory section each week...

      The reason there are no lectures on how to solve problems is because there were recitation sections. Although I did put three lectures in the first year how to solve problems, they are not included here."

      There were also a few lectures that were left out for some reason, which form the basis of the book "Feynman: Tips on Physics."

      In the preface, he also writes that he considered the course a failure. Based on examination scores, only about two dozen out of his class of 180 really grasped the subject, but those who did gained "a first-rate background in physics."

      I'm currently taking intro physics and I've found Feynman's lectures to be invaluable. It's a much more thorough treatment than my current course, and I think it will hell set me up for more advanced courses. But you're right that by itself it is not sufficient.

    Yes! The Feynman lectures are interesting, but I think that Leonard Susskind's lectures are much more clear. Susskind also addresses General Relativity in a more conventional way, without predicating the whole exercise in electrodynamics. Susskind's approach places more emphasis on the underlying geometry, centred around the metric tensor, and is appropriate across multiple applications of continuum mechanics. I think that the Feynman approach is better for those who already have a decent grasp of GR.
