For the readers from the wiskunde meisjes; mathematicians interested in Psychology:
Serendip is a site with forums for those interested in Psychology, Psychobiology, Psychofysiology and related.
In the Netherlands, and particularly in architecture, the gulden snede is very important because it's pleasant. The post in the blog that I link too is about this special relationship between aesthetics and maths.
