Wikipedia Doesn't Know What A Roof Is

And I don't really understand it myself. But Eric does.

I've been watching MIT's Professor Lewin's Physics lecture videos. He's one of the better math instructors I've ever seen, and I'm really enjoying the videos. The funny thing is, Prof. Lewin is a really funny guy, but his students never, never laugh. Ever. So I'm glad I'm not in that class.

Anyway, MIT is offering the videos to anyone who wants them, anywhere in the world, for free. The problem is, they want you to stream the videos. In Real format. **BARF**

MIT's pages for these Physics lectures are the following three links, one for each semester:

Semester 1
Semester 2
Semester 3

Fortunately, MIT themselves provide a way for you to download the videos rather than stream them. The solution, given here, is to change the link to the video from one of Akamai's servers, to one of MIT's servers. There are about 100 video files, so harvesting the links and altering them one at a time is a pretty awful process.

So, I've done the work, and I don't see any reason that you should have to also. I'm posting the links to the direct downloads on PhischX, if you want them. Again, it's about 100 videos covering three semesters of Physics lectures, and if you download all of them, you'll need about 9.5GB of free space on your hard drive. And a really fast connection to the internet, or several days to waste waiting for downloads.

So, here are the links:

    Prachtig! ("Wonderful" in Dutch) Thank you for posting this.

    I was a student of Walter Lewin (8.02), and I did laugh in his lectures. Of course, a buddy of mine and I would do our problem sets and *then* watch Walter Lewin's "Physics Help Tapes" at the library, just for laughs, though I know I learned a lot in the process.

    We invited him and his wife over for dinner one evening, and he spent the entire meal pulling toys out of his pockets: "But look at this one -- quite amazig really -- now I wind it up, and -- how does the kangaroo flip that way?!"

    When I asked why there were pens stuck to the outside of his jacket, he pulled out a huge magnet, and the pens clattered to the table, "Oh, just a magnet -- much easier than trying to get the pens into the pocket."

    "From 26-100, this is Walter Lewin, signing out"

    Thank you really much for the link, i was looking for a way to download them since these are just perfect. I would like burn them on dvd to show them to everyone who has some interest in physics. By the way, a program by PBS is really interesting, the elegant universe, you can watch it online: http://www.pbs.org/wgbh/nova/elegant/program.html
    This is really well explained and you feel intelligent since you understand a big part. The same thing here with the lectures.

  5. Thanks a lot for this I am blogging this one. I am hoping to also send to some of the science teachers I know.

  6. While I appreciate being able to download vids w/o Real as much as the next guy, there's a good reason MIT is using Akamai to distribute these, and now that this page is on del.icio.us/popular, you're really going to cost them a lot of bandwidth.

    How about hosting torrents instead? Or using Coral CDN?

    Oh fabulous! I've been wanting to burn these to a DVD for safe keeping. I homeschool our two children, but they aren't quite old enough yet to study at this level. You've saved me a lot of time that I otherwise may not have been able to find.

    Thank you.

  8. Thank you very much.

    Very interesting and useful

  9. In case anyone is on slow connections, there seem to be 56k and 80k versions too, of the first 300k file at least. Just substitute "300" with "56" or "80".

    To find them with bash:

    for i in 2 3 4 5 6 7 8 9; do
     for j in 0 1 2 3 4 5 6 7 8 9 0; do
      wget http://[..]${i}${j}k.rm;
     done;

    Thank You. Could you group all the semester's lectures into one file?

  11. Thank you, Sir. You have no idea how thankful I am

    do you have other lectures from MIT ?
    It would be great if you do.

    Thanks a lot.
