## Feynman Lectures on Physics Vol. 1 Released in HTML Format129

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.)"

I'll get to the copyright in a minute. But there is actually a huge bit of inaccuracy in the post. The videos at Microsoft research in *NOT* the Feynman lectures on physics. Those are actually a part of the Messenger Lectures recorded at Cornell in 1964 called "The Character of Physical Law" and preceded the Cal Tech undergraduate physics lectures which we now know as the Feynman Lectures on Physics.

Bill Gates has long been a fan of the lesser known Messenger Lectures. As part of the drive to popularize Silverlight, he actually acquired the rights to "The Character of Physical Law" in order to be able to present them to the public using the Silverlight platform at Project Tuva. Not a bad move for like minded Feynman fans like me.

It may have something to do with stuff that can't be rendered properly in HTML. The web presentation is full of equations rendered like this:

$$\label{Eq:I:39:2} dW = F(-dx) = -PA\,dx = -P\,dV.$$

I assume that is rendered as a proper equation in the hardcopy!

The good news is that the web presentation is searchable ASCII text, which a bit-mapped scan would not be.

HTML works better in this case. PDF is better when you need the formatting to be the same on all the devices, but that is not the case here.

With HTML, the user can adjust the size and have the text reflow, and can separately scale all the math (see the MathJax context menu on any equation to access the math scaling settings).

For instance, the HTML edition is quite usable on even my iPhone, with my poor 50+ year old eyes. For a PDF to be usable on such a device, they would have had to format it in such a way

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.
