SANDstorm, Math-Fun, & Asteroid Relocation

Google Tech Talk July 24, 2009 ABSTRACT Presented by Rich Schroeppel. Rich Schroeppel works on SANDstorm, the Sandia entry in the NIST contest for a new cryptographic hash function. He'll also present some math fun: Post's Tag Problem, and Polyhypercubes. Then there's a proposal for moving asteroids to useful orbits, and to close, the Fish-Pond Theory for the origin of life. Bio: Rich Schroeppel has an Erdos number of 2, coauthored MIT's famous 1972 HAKMEM, and factored Mersenne numbers M137 & M149.
