How a physics professor sees the world

For many of us, physics has a tantalizing, but a kind of scary math-intensive caché about it. For Andy Rex—a fixture in the physics department for more than 35 years—it’s just baseball.

Thermodynamics, heady stuff about heat and energy, is his specialty. In particular, he likes to spar with a tricky little anomaly known as Maxwell’s Demon. He embarked on that research project only after he’d mathematically exhausted parsing the speed, spin, and curve of a baseball—the focal point of the game that is his other great love.
