Mathematics is an amazing and beautiful intellectual creation, one of the human race's deepest endeavors. The world around us, and the future world we are creating, is woven through with mathematics — from the symmetry groups of Navajo weavings, to the airflow around a flapping bird’s wing, to the security of global computer networks.
