Science fiction writer Catherine Asaro is also a ballet dancer and a math teacher who believes that physics and dancing are much more closely related than you might think. Both are about spatial perception, and "ballet is very much about algorithms and patterns, and numerics," says Asaro. "Everything we do in an exercise, for example at the bar, is an algorithm. And you learn them, they become incorporated in our body." And then there's the classical music connection. "We've known for a long time that many mathematically oriented people are also very musical," says Asaro. "And even Bach, there have been whole analysis of the mathematics of his music; you get that in dance, too."
