Fun With Geometry

March 1, 2005 12:10 PM

The Geometry Center at the University of Minnesota, while now closed, maintains an awesome website with tons of math resources. I like sphere eversion, i.e. turning a sphere inside out. Link is to script of video, which explains things pretty well. Here is a clip [QT]. Also good: notes from a class on geometry and the imagination that John Conway and some friends gave awhile back. Old but good.

Sincere apologies if this rather old site is a double post. I checked.

Note that the sphere, when being turned inside out, is allowed to pass through itself, but no holes can be cut and the surface must remain smooth (i.e. no kinks allowed).

This Lorenz equation simulation is pretty cool, but several of the web applications seem to be broken. Is that perhaps a consequence of the site as a whole being hastily rescued by somebody at Urbana-Champaign?

Is there more story here? Why is the site for the former Geometry Center at U of M hosted at UIUC?

In any event, I heartily endorse this post. Thank you.
