Mathematics art in The University of Manchester

While walking randomly, the guy behind http://www.walkingrandomly.com/?p=4203 discovered something interesting on the windows of an old building from The University of Manchester. This mathematics themed stained glass window is part of The Sackville Street Building and it seems that other mathematical windows can be found in buildings from around the world, including Caius College, Cambridge.

Tautochrone curves

This is pretty neat! A tautochrone curve is one where the time taken by an object sliding down (without friction in uniform gravity) to the bottom is INDEPENDENT of the starting position. As seen above, all four points end up at the bottom at the same time! More info on wikipedia: http://en.wikipedia.org/wiki/Tautochrone_curve
