In the Future, We Will Know Nothing as Well as We Know Every Action on a Baseball Diamond
From The Only Rule Is It Has to Work: Our Wild Experiment Building a New Kind of Baseball Team by Ben Lindbergh and Sam Miller:
Lead length [by a baserunner contemplating stealing] is one of many new measurements made possible by Statcast, a system installed in every major league park for the first time in 2015. Statcast combines a Doppler radar array that takes two thousand readings per second with a network of high-definition cameras that capture images thirty times per second, producing a three-dimensional record of every action on the field: every player's position at every instant, as well as the speed, spin, and trajectory of every thrown and batted ball.
The book is about two stats heads (the authors) who run a semipro baseball team in Northern California for a season, and try to remake it according to SABERmetrician logic. It's about where they're right, and wrong, and what happens when statistical probabilities collide with reality. Well-written by both, who alternate chapters, although I did keep losing track of which player was which.
I'm a baseball fan, but the above makes me wonder whether we're spending too much time on the national pastime. If we're going for a three-dimensional record of every action on a particular field, the floor of Congress might be a better place to start.
