Mathball By Larry Hodges You are a baseball fan, sitting in the centerfield seats eating an overpriced hot dog. You are wearing a baseball cap, but not a batting helmet, of course. (Why would that be an issue? Hmm…)You smile brightly, but all will not end well for you unless you pay close attention. “Play ball!” cries the umpire, crouching behind the plate. The crowd roars. The pitcher stares down at the catcher, waiting for the sign. They are the home team. Thousands cheer for them. The batter waves his bat menacingly. He is a hero of this story. Six scientists sit at their desks behind home plate, three on the third-base side, three on the first-base side. The three on the first-base side work for the pitcher and we don’t care about them—they are the enemy. The three on the third-base side work for the batter. They are from MIT. These latter three are the real stars of this story. Well… mostly.
