Tennis Topic of the Day: Geometric Thinking (David Foster Wallace)
"[T]ennis, like pool, requires geometric thinking, the ability to calculate not merely your own angles but the angles of response to your angles. Because the expansion of response-possibilities is quadratic, you are required to think n shots ahead, where n is a hyperbolic function limited by the sinh of the opponent's talent and the cosh of the number of shots in the rally so far." Derivative Sport in Tornado Alley (An essay), David Foster Wallace from On Tennis: Five Essays, (Little, Brown: New York 2014)
