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: – 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

I have compiled a list (1500+) of math videos at . 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

For a course on cluster algebras (by S. Fomin):

EDIT: Some graduate short-courses in FCEyN, UBA, Buenos Aires, Argentina:

  • J. Harris, Intersection Theory
  • R. Hartshorne, Introduction to Deformation Theory
  • D. Maclagan, Introduction to Tropical Algebraic Geometry
  • P. Beelen, Algebraic Geometric Codes

Here are the links to the videos of these 4 lectures.

At the time of writing, Rutgers experimental mathematics seminar has over 200 videos up on youtube. I wish more seminars would do this!

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, though it isn't labelled as such.

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

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.

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

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 know of some youtube channels with good content. The last two link are not strictly pure math, but still worth a look.

Institut Henri Poincaré:


Institut des Hautes Études Scientifiques (IHÉS)


Simons Institute:

Any video on

Jos Leys "Mathematical Imagery"

is a true masterpiece, and has a non-trivial mathematical content...

The first Minerva Lecture by Jean-Pierre Serre at Princeton in Fall 2012 is online. There were two other lectures, and they did videotape them, but I can't find them online.

As of today, the digitized tapes of CBMS Lectures on Probability Theory and Combinatorial by Michael Steele are online. I heartily recommend them — the style is informal, but educating: there are jokes, juggling lessons, speculations about the stock market, and all of these amidst beautiful mathematics.

I am quite surprised to see Dan Freed's lecture of Hodge Conjecture has not been mentioned. (Although it is an old thread I believe this should be in here. Before there was a QuickTime video but I am grateful to find that it has been youtubed.)

I make some maths videos at home,Here is an English video:Visible Fibre Bundle

maybe that can help some begginners.

All my maths vedios at my blog here,thirty courses of communtative algebra and I prepare to make much more in the future,but as you seen,most of them are Chinese(中文),because I can not say much English.

I am not sure if this will qualify as math exactly, but it's amazing nonetheless. It is a film with Richard Feynman called "Feynman: Take the wold from another point of view". Here is part 1

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.

Excellent lectures by Norman Wildberger on topics including: Geometry, Algebraic Topology, Linear Algebra, Foundations of Mathematics, and history of Mathematics

share|cite|improve this answer
Watched a few Videos. But Wildberger is often trying to push his own views onto students, which he calls "Rational Trigonometry" (as in, Angles should be 0 to 1 instead of 0 to 2$\pi$. This makes the videos hard to watch, as they are not consistent with other books/lectures. – Michael Kissner Jul 20 '11 at 8:23

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

Richard Feynman gave the 1964 Messenger Lectures at Cornell University --- this is an endowed lecture series to which a number of famous scholars have been invited, including several physicists. His lectures were recorded, and Bill Gates bought the rights to them and has provided them to the public for free.

The content is mostly designed for a general audience, so if you have never learned physics you will learn something. And if you have studied plenty of physics already, you will be pleased to see the master at work in his prime. I very much enjoyed watching it.
