The Feynman Lectures on Physics Audio Collection
- bassman9000 5y agoThis would be a great project for ML-enhanced audio.
- paulz_ 5y agoI've listened to a few things lately that could benefit from that. You wouldn't happen to know any good models available for that would you?
- cjauvin 5y agoI really wanted to follow this class taught by Steven Pinker [1] recently, but the audio becomes so bad after the first lecture that it's almost impossible to follow. It made me also think that there could probably be some interesting post-processing applied, to improve the quality.

- base3 5y agoRemarkable. Thank you!
- kragen 5y agoIs it just me, or is Feynman's voice clipping a lot even in the first couple of minutes?
- jawknee4000 5y agoI think it's just the first lecture, the tape of which was damaged somehow - https://twitter.com/preskill/status/1398371618372526080 https://twitter.com/preskill/status/1398371618372526080.
- agogdog 5y agoIt's a shame the quality fades in and out! it's unintelligible at times
- polishdude20 5y agoIs there a way to download these?
- loxias 5y agoThe URL to the media file is easy to see in inspector, in firefox or chrome. it downloads happily with curl as long as you preserve the cookies. The filenames follow a (mostly) predictable pattern, amenable to a simple for loop. After downloaded, I extracted the audio with ffmpeg.
- captn3m0 5y agoJust renaming to M4A should also work - the MP4 files only have a audio stream.
- captn3m0 5y agoFor MP4 (2.6GB) wget -qO- "https://hastebin.com/raw/amekevecum" | wget -nv --referer="https://www.feynmanlectures.caltech.edu/flptapes.html" --user-agent="Mozilla/5.0" --input-file - For OGG: wget -qO- "https://hastebin.com/raw/esukabunew" | wget -nv --referer="https://www.feynmanlectures.caltech.edu/flptapes.html" --user-agent="Mozilla/5.0" --input-file - Titles are here: https://www.feynmanlectures.caltech.edu/flpplaylist.js https://www.feynmanlectures.caltech.edu/flpplaylist.js
- syntaxing 5y agoWow this is awesome. Like other has asked, is there a way to download these? Would love to listen to these when I’m driving or at work.

- WalterBright 5y agoOh I wish I could tell my past Caltech student self to tape record the lectures. Feynman gave a guest lecture to our freshman Physics class about potato chip worlds. I wish someone recorded it. It simply never occurred to me, or apparently anyone else, even though those portable Radio Shack cassette recorders were around.
- Teever 5y agoPotato chip worlds? Go on...
- caturopath 5y agoThe first thing that came to mind was a hyperbolic universe.
- WalterBright 5y agoWorlds that appeared flat to the inhabitants but had weird geometry because they were curved in strange ways. The point was how your perspective could hide your world's true nature.
- cb321 5y agoAh, yes. Following in the delightful tradition of Flatland [1]. Rudy Rucker's Geometry, Relativity and the Fourth Dimension (1977) may be a fun read {perhaps less fanciful than Potato Chip World} for those interested.

- adamnemecek 5y agoFeynman lectures are the SICP of physics. Out of date, not all that relevant but fetishized to death.
- bitexploder 5y agoAs a layperson to physics, I really appreciate his approachable style, both in writing and in speech. Do you have any suggestions that are as approachable and fun for technologists interested in physics?
- op03 5y agoKhan Academy hands down. Mainly because they give you a map and a road map if you will to explore the subject. Long way to go to improve the map and ways to explore it based on individual personality and skill levels but that will happen with time.
- deleted 5y ago[deleted]
- Grustaf 5y agoKhan academy is great, but nothing is quite like listening to a certified genius.
- bitexploder 5y agoI think that is part of it. You can catch glimmers of how Feynman thought process worked. How he sees the world. And that is really cool.
- adamnemecek 5y agoPhysics from symmetry is good.
- truth_ 5y agoOut of date? Sure. But it still adds very valuable insights, and new perspectives. Feynman Lectures are great. Especially Vols I and II. Just because something has a community fetishizing it, it does not lose its value because of that. I read most of Feynman Lectures in my undergrad, and the experience was profoundly rewarding. It is not about gaining up-to-date knowledge of the topic. It is about learning the core and crux of the subject, and how to think about the subject.

- otaviogood 5y agoI thought it would be nice to listen to these with my podcast player on iphone. Here's my too-complicated process that worked: - in Chrome inspector, look at the network tab when you click play on a Feynman lecture. Right click the mp4 and do "copy as cURL". - Go to command line (unix style) and paste. Then append to that command line something like "--output flp1.mp4". That will download the file locally with that file name. - Put the file on Dropbox or something that will get it to your phone. - From dropbox on iphone, share and export the file, then choose your podcast app. The podcast app that worked for me is "Pocket Casts". - Now in Pocket Casts -> Profile -> Files, you should be able to play the mp4s with nice podcast-style controls and learn physics and be happy!
- captn3m0 5y agoThere's a wget one-liner here to download everything: https://news.ycombinator.com/item?id=27323235 https://news.ycombinator.com/item?id=27323235
- JKCalhoun 5y agoThanks. Required 'brew install wget' first for me. ;-)
- jacobmischka 5y agoNice, I tried doing the same, but by writing the curl command myself. It failed, it seems it requires ~the cookies~ because I was getting 403s. Thanks for the better idea! Edit: Looks like all it needed was the Referrer header.
- siraben 5y agoAre there accompanying slides or pictures of the blackboard for these lectures?

- simondotau 5y agoThere's a potential subset of people who don't know who Richard Feynman is, but might recognise a segment of one his lectures from the movie theatre puzzle in The Witness (the 2016 video game by Jonathan Blow). https://www.feynmanlectures.caltech.edu/fml.html#5 https://www.feynmanlectures.caltech.edu/fml.html#5 (The section clipped in The Witness begins at 38 minutes, 34 seconds.)
- mwcampbell 5y agoI bought The Witness (the PC version) a couple of years ago, even though it's not a game that I'm inclined to try to play (and I might not even be able to play it). I bought it partly because I was inordinately curious about superficial packaging details like whether or to what extent dynamic linking would be used, how assets would be bundled, and whether they would be obfuscated so they couldn't be viewed or played outside the game. But I also bought it because I knew it had some interesting audio and video recordings, like a recording of Brian Moriarty's lecture "The Secret of Psalm 46". Anyway, I found the audio of that Feynman clip you referenced, and it was indeed playable outside the game, in an ordinary audio player. Now I'm curious about this movie theatre puzzle and the significance of the Feynman clip in the context of the game.
- jasonwatkinspdx 5y agoIt's not a game for everyone, but I'd suggest giving it a reasonably serious try if you're curious. It's by far my favorite puzzle game, and I generally do not like puzzle games. I played through it with a local retro gaming group over a series of sessions. That made it a lot more relaxed and fun, as we could share the mental load when getting a big fatigued. Most of it we could figure out through simple intuition, persistence, observation, etc, but there is one puzzle at the end that we hand to resort to pen and paper, coming up with a formalism for it. All in all it was a really cool experience.
- rcshubhadeep 5y agoThis made my day! Thank you so much :)
- tomerbd 5y agoI don't understand why everyone so much adore feynman lectures there are plenty of other prof. who explain much much better for example suskind
- engineeringwoke 5y agoFeynman is an engineer's physicist, and we're on an engineering board afaict
- TheGallopedHigh 5y agoThat doesn’t make sense. Every physicist is an engineer and vice versa
- karatinversion 5y agoEver heard of string theory?
- dev_tty01 5y agoI would say every physicist believes they are an engineer...
- Grustaf 5y agoSusskind is great, and he's very much inspired by Feynman. Of course there are plenty of good professors that will help you understand physics, but I haven't heard anyone lecture in such an interesting way, have you?
- publicola1990 5y agoYes, I find Leon N Cooper was also very good at explaining physics. His 'Meaning as Structure of Modern Physics' is as good an resource for freshman physics as Feynman lectures. Also there are topics Feyman himself thought was covered hastily, if I recollect correctly, and that included thermodynamics.
- beagle3 5y agoMy theory is something I call "The Feynman effect". Feynman has a talent of making the listener believe that they (the listener) understand everything at a very deep level. So it gives the feeling he's an amazing teacher -- and if you don't actually try to apply that knowledge, you might never notice that you're wrong. I realized that after reading his lecture on "the principle of least action" coming out with the feeling that I deeply understand (among other things) calculus of variations - a field I didn't even know existed until I read that. So I tried to use it -- and realized that, other than recreating Feynman's example, I can't really use it for anything. I shared the sentiment with others over lunch the next day (a couple of other undergrads and two graduate students), and they were all familiar with that feeling....
- 29athrowaway 5y agoIt would be good if some audio engineer could somehow remaster these.
- 29athrowaway 5y agoFeynman started fixing radios and antennas as a kid. During the Great Depression, people did not have enough money to hire a radio repairman, so they hired him instead. He started taking incrementally more difficult jobs, until he got very skilled at it. Another cool fact about Feynman is that he had some built-in syntax highlighting for equations in his head. A very specific type of a condition known as grapheme-color synesthesia.
- okareaman 5y agoFeynman used to think about the problem before doing anything, so his neighbor asked him why he wasn't working on the radio but standing there staring off into space. After Feynman fixed his radio, his neighbor told everyone in amazement "He fixes radios by thinking!" You could take this to mean he thinks about the problem first, but I think the neighbor (this was in late 1920's, early 1930's) meant that he was was amazed because Feynman appeared to reach into the radio with his mind to fix it.
- 29athrowaway 5y agoIt was after that that he enrolled into every physics class he could. I think being exposed to early electronics (before transistors) must have been an incredible learning experience for a kid.
- MengerSponge 5y agoPhysicists joke about the Feynman Problem Solving Method: 1) Write down the problem. 2) Think really hard. 3) Write down the solution.
- erwinh 5y agoWait what?? There were audio recordings of these???
- quantum_state 5y agoAs always, it is a great pleasure to listen toFeynman talk ...
- vessenes 5y agoSo much dislike for these! I dug through Apple’s audio book section at some length and purchased Feynman’s overall survey of math, a sort of toss-off in the middle of his physics lecture series, and I love it. It’s just the most profoundly enthusiastic holistic summary of basic mathematics I can imagine packed into a one hour talk. I’m going to listen to it again today. The pleasure of these lectures is getting to spend a little time in Feynman’s head, appreciating the world the way he does, unpacking it the way he does. I don’t think they deserve the side eye - they’re a really unique product of a very unique person, and a culturally valuable thing to have around.
- amai 5y agoFeynmans last lectures have only been published last year: https://arxiv.org/abs/2006.08594 https://arxiv.org/abs/2006.08594
- intellaughs 5y agoThank you for this! Can't wait to try to start listening to these during workouts.
- dvk13 5y agoThank you for the share @sohkamyung. Anyone else noticed that its missing lecture #21?
- sohkamyung 5y agoYou're welcome. :-)
