Original email from this morning to give some color:

Dear Feynman Lectures Forum Members,

Have you ever wished there was a high-quality up-to-date version of The Feynman Lectures on Physics available online? One that could be read with a browser so you could study FLP on your smartphone, tablet, notebook or desktop computer, whenever you felt like it? For free? Well, now there is, and you are among the first to hear about it!

A few words about the free HTML edition of FLP (New Millennium Edition)

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.)

When you read our HTML edition you will notice a floating menu in the top right corner with Twitter, Facebook, and email buttons (to tell your friends about it!), navigation buttons ('last chapter,' 'table of contents', and 'next chapter'), a "contact us" button (that sends email to me), and a "Buy" button that links to a page of advertising for our books and ebooks, with links to retailers' web pages. To support our effort in producing and maintaining the HTML edition, and to help us keep it free, I would appreciate it very much if you would take some time to explore the retailer's pages through the links on our "Buy" page.

Enough said!

You can access the free HTML edition of FLP either by going to the home page of www.feynmanlectures.info and clicking on "Read," or you can go directly to it at either of two servers:

www.feynmanlectures.info/flp or www.feynmanlectures.caltech.edu

(So what's the difference between the servers? I maintain the site at feynmanlectures.info, so changes are reflected there immediately. On the other hand, feynmanlectures.caltech.edu is generally faster and more responsive. The entire edition is mirrored from feynmanlectures.info to feynmanlectures.caltech.edu every day, so the latter is current within 24 hours.)

- hope you enjoy the new edition! If you like it, please tell your friends.

Best regards,

Mike Gottlieb Editor, The Feynman Lectures on Physics, New Millennium Edition

P.S. If you've received this email more than once, I apologize. We're having some problems with our mail servers this morning!

I've always felt that the one thing missing from my education was at least some basic understanding of physics. I've flicked through the chapters and I have come across many topics before but by proxy of other subjects such as game programming,chemistry and some applied math. Now I have a book to read that will plug obvious gaps in my learning. I particularly like the 'relativistic' illustrations in the units of scale chapter. The descriptions on durations less than a day are quite illuminating and enjoyable. It's funny that I have spent years learning to build huge complex concurrent distributed systems and compute Monte Carlo simulations on clusters, all very abstract and intangible; and yet I have been intimidated with anything beyond a pop culture knowledge of physical phenomena. Thank you for the book.

BTW - Nice touch on the equations.

ThIs is wonderful...I have PDF copies of this from some forgotten torrent long ago and had consider trying to make them parseable but never got around to it. I can understand why they still want to make book sales from it...hopefully this will actually spur people to buy the books after they are able to sample them online

Every single one of those old PDFs, especially OCRs, are full of errors, now corrected in this edition. There's a long history of errata, old and recent, and in which editions they were corrected, at feynmanlectures.info

Thank you so much for doing this!
