I know of two good mathematics videos available online, namely:

  1. Sphere inside out (part I and part II)
  2. Moebius transformation revealed

Do you know of any other good math videos? Share.

    The sphere eversion video is available in one part on Google Videos: bit.ly/2Bmj3Z – Harrison Brown Oct 21 '09 at 20:33

    Also, shouldn't this be community wiki...? – Harrison Brown Oct 21 '09 at 21:57

    @harrison: yes. @Justin: please make these kinds of posts (anything where you say "one answer per post") community wiki in the future. Do not just wait for a moderator to forcibly convert it to community wiki. – Anton Geraschenko Oct 21 '09 at 22:51

    The sphere eversion video is great, and it seems like a really good way to explain topology and the idea of an invariant to a non-mathematician. On the other hand, I wouldn't expect someone to sit for 20 minutes just to find out what I care about. Does anyone have recommendations of shorter videos that achieve similar goals? – Aaron Mazel-Gee Oct 22 '09 at 6:26
  • @Anton Sorry, I didn't know how to make community wiki questions, nor did I know how to change to community wiki postmortem. Now I know. :) [The 'community wiki' checkbox is probably too small and pale.] – Randomblue Oct 23 '09 at 10:22

I have compiled a list (1500+) of math videos at http://pinterest.com/mathematicsprof/ . If anyone is aware of others, please send them to me.

    Did you go through the all the videos in this question? – Randomblue Aug 24 '12 at 4:19

77 instructional videos on category theory:


I know you said "only one video per post", but I'm not posting 77 times...

    Gosh! Are they up to 77 now? – Loop Space Oct 22 '09 at 7:54

Most of the talks at MSRI are videotaped and placed on the web here:


My personal all-time favorite is the Klein Four with their song "Finite Simple Group (of Order Two)"... it has lots of puns on topology in it, but I guess it doesn't teach anything.

Here's the link to the "Finite Simple Group" song

    The song may not teach anything, but I think it's contributed positively to my education! Listening to it every once in a while gives me evidence that I'm actually learning stuff, because the song keeps getting funnier. ^_^ – Vectornaut Apr 19 '10 at 4:55

I believe this was mentioned elsewhere, but for completeness, here's Serre on writing.

  • My favorite quote from this video (among many great quotes): "I'm sure that if this happened with Bourbaki, some member of Bourbaki, he would tell the other one, "It is because you are stupide and you have not found the correct statement, which would give both of them!"" – Harry Gindi Apr 23 '10 at 14:56

The Newton institute in Cambridge tapes alot (all?) of it's lectures, and they can be found on the Institutes webpage. High quality for videos of lectures.

This video about Andrew Wiles and the proof of Fermat's Last Theorem is the only time I've seen the real excitement of mathematics presented accurately.

  • Thanks! I just watched the video! I can't even imagine the pressure Wiles got when the proof was Almost there, but just almost, after having announced the result! – IamMeeoh Feb 20 '11 at 23:38

'Not Knot' is also a nice vid

    It's not only nice: it's great! – Hans Stricker Mar 4 '13 at 23:23

At the accessible end of the scale, Vi Hart's "doodling in math class" series and subsequent videos are a delight.

GRASP is a new lecture series at the University of Texas at Austin, which is aimed at bringing some of the fundamental concepts and big picture of the GRASP areas (Geometry, Representation, and Some Physics) to a wider audience (the intended target audience are beginning graduate students).


  • they have videos of G. Segal and lurie, it is pretty cool – Sean Tilson Apr 17 '10 at 23:09

The Institute for Advanced Study tapes some of its lectures. They tend to be very good.

  • I just found this link a couple of days ago. It is cool indeed :) – Dmitri May 29 '12 at 21:44

You probably won't learn much actual math from it, but One Geometry is funnier and catchier than a Snoop Dogg parody about 3-manifolds has any right to be.

  • Funnier and catchier... yes. And I did learn a bit of Math :) – Rodrigo A. Pérez Dec 15 '12 at 5:23

Along the sphere eversion lines, there is also the energy-minimizing sphere eversion constructed by Rob Kusner. I think there is a video of it at http://www.youtube.com/watch?v=I6cgca4Mmcc, though it isn't labelled as such.

Rob also has written a paper about the history of the minimax eversion.

My personal favorite in Dimensions, that was mentioned before by Gerald Edgar. For a neat and clear exposition the Geom.of 3 manifolds, Poincaré conjecture, etc I recommend this lecture by C.McMullen. Or Das Schöne denken (hosted at the HIM in Bonn), for a good "glimpse in the world of the mathematician". Jos Leys' mathematical imagery contains some (interesting) videos and (a lot of beautiful) images.

There are Stephen Boyd's lecture videos on convex optimization:


I guess all of John Conway's lectures are great. Some of those can be found here : http://www.math.princeton.edu/facultypapers/Conway/

Not lecture videos or anything, but the stuff from Oliver Labs is very good for just illustrating geometric stuff, like blowups and dual curves.

The IHES also has a lot of on-line videos. In particular, I like very much the ones from the "Colloque Grothendieck".

Dror Bar-Natan has begin putting many of his lectures and talks online in video format. I'm not claiming that these are the 'best' online maths videos, but they're certainly interesting, and in particular he's come up with some neat tricks to associate publicly editable annotations with particular moments in the video.

I am surprised that nobody mentioned the four-week workshop at Göttingen on arithmetic geometry in 2006 summer. Almost all of the videos are still available. Wonderful videos.

This is an old thread, but this video was recently posted to the Don Davis topology list, and I have to share it. It was created by Niles Johnson at UGA and it illustrates the Hopf fibration.


This one is quite old but it was fun when I watched a few years ago. It's about Fermat's Last theorem.


Videos recorded at IMPA:


(some in English, some in Portuguese)

The "Touching Soap Films" series by Springer. about minimal surfaces. Some excerpts of the video are available here: http://page.mi.fu-berlin.de/polthier/video/Touching/Scenes.html

This video is less about mathematics, but about a fascinating mathematician in two bodies who helped saving medieval unicorns - students liked it.

  • This is a very cute story! For people who'd prefer a slightly less cryptic description: the video is about two brothers, both professional mathematicians, who helped the Metropolitan Museum of Art construct a high-resolution digital image of a medieval tapestry. The tapestry had been photographed in thirty or so overlapping chunks, but the chunks didn't fit together into a consistent image. With the help of a graduate student, the brothers tracked down the source of the mysterious inconsistencies, and then figured out how to correct them. A nifty application of math---well worth watching! – Vectornaut Apr 19 '10 at 5:36
