Virile hobby programmer of robots that sort piles of pebbles into step in and destroy ground portraits - at least if that's what my kids want for an art project. Occasional volunteer math teacher, much beloved but greatly feared and reviled for introducing the Dresden Codex and Mayan mathematics to second graders. Undeniably terrible at playing the guitar and writing software apps for the i-phone. Less terrible at chemistry, flavor chemistry, statistics, research and development.
