Baseball’s Alternate Universe
There’s a New York Times op-ed this morning from a couple of guys at Cornell who decided to figure out just how impossible Joe DiMaggio’s 56-game hitting streak was by running simulations of every at-bat of every year from 1871 to 2005. Oh, and they did it 10,000 times.
In essence, we programmed the computer to construct an enormous set of parallel baseball universes, all with the same players but subject to the vagaries of chance in each one.
They wanted to see how likely it was for any player to match that streak. The results? Surprising!
In each of these simulated histories, somebody holds the record for the longest hitting streak. We tabulated who that player was, when he did it, and how long his streak was.
And suddenly the unlikely becomes likely: we get a very long streak each time we run baseball history. [...] The streaks ranged from 39 games at the shortest, to a freakish baseball universe where the record was a remarkable (and remarkably rare) 109 games.
