Feynman Lectures on Physics Vol. 1 Released in HTML Format 129

Posted by Soulskill
from the surely-you're-joking dept.
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.)"

          This page [caltech.edu] says Caltech holds the copyright. Presumably they require(d) that faculty transfer copyright of works they did in the course of their employment to the university. My guess is that's probably standard provision for faculty, though I'm not positive.

            I don't know what the policy was when Feynman made that, but Caltech's copyright policy was (and still looks like) that copyright of books, papers, written work, and stuff related to classes remain with the author unless specifically funded by Caltech (above and beyond simply being an employee there). And when they do get the copyright, you get a portion of the royalties, or can chose to donate a portion of your share to research in a field you specify, and Caltech will match your contribution from their p

          I guess it also helps that it isn't a book that's been published recently - being an older title, sales are probably thin to begin with. An online copy can easily be a good marketing mechanism in that case.

      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.

      Yeah, I had the same question.

      My guess is that it's the "book sales would not be harmed" qualifier, with the assumption that just posting good PDFs would harm sales and an HTML version wouldn't.

      I'm not sure how they got to that conclusion, but that's my guess anyway.

        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:

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

        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.

          OK, I now found a cached version of the web page that actually works properly, and the equations are indeed rendered correctly.

            Nah... a printed web page will only print even remotely close to the quality of a real typeset book if a lot of effort was expended on creating CSS specifically for printing, and even then you probably can't get even all that good. (Could you even get a table of contents with page numbers? I dunno.) And that basically means that it wouldn't happen.

            ``So why can't you just print the pages out to PDF?''

            I'm guessing that the results wouldn't be very good.

            One could cut-n-paste the text from the web page into a LaTeX skeleton document and process the file as you would any other LaTeX document. (After editing to put in proper LaTeX chapter/section/subsection/figure/includegraphics/etc. markup tags, that is.) It would be a fair amount of work but doable for the motivated but cash-strapped (and ethically challenged) student.

        Personally, I hope they extract every last dime they can by running a terminal command and farting about the web for the other 8 hours of the day. However, I'm sure it has more to do with web formatting and hosting, links and other such things than getting paid to do nothing.

      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

      PDFs are static in the sense that you can't change the page dimensions once you create the PDF. Imagine, if the PDFs were created in book format (2-up) and you had scroll up and down to read the the text. The problem would be worse for people on the move who have to use tablets. OTOH HTML ..

    I assume this was expensive because TeX4ht wasn't up to the task. Was TeX4ht used as a starting point for the conversion tool? Is someone now maintaining an updated TeX4ht? Is the converter available in CTAN?

    Surely you didn't spend all this money having people manually convert one structural markup language to another, instead of investing in tools to do it automatically, right?

    • by fnj (64210) on Friday September 13, 2013 @12:58PM (#44841813)

      The TeX source for the equations is just embedded in the text of the page. The use Javascript to render them. I'm not sure why that was expensive.

    • Editing is more than just conversion or reformatting - it's also ensuring that the conversion/reformatting operated correctly and did not induce any errors snd that the process produced reasonable and useful output in the target format. (I.E. leave it Slashdot to concentrate on the 1% of the task that can be automated.) Editing is one of those thankless tasks, because done right it's invisible.

    • Afaict the problem is a practical latex document is likely to use a mixture of structural constants, "just put this where I damn well tell you to" constructs and constructs that while nominally strutural are being tweaked to make things look good on the printed page (for example moving a figure up or down in the text so it ends up on the page you want it on).

      An automated conversion is likely to produce something that is just about readable but a high quality conversion is likely to require human judgement.

      I wonder how much the rights holders would want to release the Feynman Lectures into the public domain, or a CC license that will ensure free access to this text.

      After all, the Feynman Lectures cannot be that valuable to them. While it is widely recognised, it is definitely directed towards people specializing in physics and engineering. As far as I know it's rarely used as a course text either (age, lack of supporting curricular materials, etc.).

    Many philosophers would disagree with that.

      I just read the chapter on symmetry, and that is a bit out of date in that while it correctly explains that parity symmetry is broken, it still incorrectly claims that parity-charge symmetry holds, which we now know is false.

      The lectures are very educational and engagingly written, so I recommend that you give it a go anyway. If you take it all on face value, you will end up with only a very few, minor misunderstandings.

    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...
