Queer as a 3 dollar bill and hit on all the male students. I never took a class from him. But I sat in his office for many long hours as he discussed whatever the latest frontiers were in artificial intelligence, mathematical modelling, the history of mathematics, and the like. I was mad because his course was full; it was something about how mathematics relates to the Universe, fractals, patterns and stuff and I wanted in. This was WAAAY back in 1990. So instead, I hijacked him outside of classes and begged him to be my adviser for a semester.
