Center of Points in 2- or Higher-dimensional Space
It provides important formulations for finding a center of points in 2 or higher dimensional space. It can be used in drawing delauney triagulation and voronoi diagram in two or higher dimensions. It also describes how many points are required in defining a center in n-dimensional space.

NPR : Mathematicians Get Crafty with Geometry
A husband and wife from Cornell University have come up with a crafty way to illustrate high-level geometry concepts -by manipulating yarn into models that help explain the curvature of spaces. The mathemeticians talk with NPR's Jacki Lyden about hyperbolic crocheting. [4:47 streaming audio broadcast] (March 13, 2005)
