### Beautiful new geometry videos

Thursday, February 04th, 2010 | Author: Konrad Voelkel

On dimensions-math.org you can see a whole bunch of before unseen geometry videos introducing 2-, 3- and 4-dimensional space, complex numbers and even more to the non-mathematician (somewhat similar to the well-known Not-Knot-videos and the Moebius transformations on YouTube, but with lots of explanations). The computer animations are available on DVD and online, for free. The explanations are in many different languages.

This is something not to miss if you're interested in mathematics, and it might also be valuable if you're taking a first course in complex analysis. Even after you've taken a course on complex analysis, you might enjoy the animation of the Hopf fibration (which I liked most).

Go straight to watching the videos in English.
