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

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

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

Marcus du-Sautoy's lecture - Music of The Prime Numbers, is a very nice popular talk about prime numbers

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.

Any video on

Jos Leys "Mathematical Imagery"

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

Documentary about infinite and its implications in mathematics (BBC)

As usual, Gregory Chaitin on the history of logic

Another one about logic and artificial intelligence

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
