Mathematica 10.1 A Calabi-Yau space is a mathematical construction that describes parts of nature that are too small to see with the human eye. It is named after E. Calabi who first studied them, and S. T. Yau. Calabi–Yau spaces are manifolds that satisfy the requirement of space for the six “unseen” spatial dimensions of string theory. From a script by Andrew J. Hanson.
