Math Awareness Month

An anonymous reader writes: April is Mathematics Awareness Month. Mathematics of the Cosmos is the 2005 theme: Mathematics is at the core of our attempts to understand the cosmos at every level: Riemannian geometry and topology furnish models of the universe, numerical simulations help us to understand large-scale dynamics, celestial mechanics provides a key to comprehending the solar system, and a wide variety of mathematical tools are needed for actual exploration of the space around us."
