"[I]n the mid-19th century math seemed... useless for physicists pondering the complexities of molecular motions in gases. ...How could anyone grasp the inner workings of a mass of molecules too numerous to count and too small to be seen? Yet... Maxwell found a way, by using statistics—mathematical descriptions of large groups of molecules. ...Maxwell got the idea to use statistics in physics from social scientists applying math to society!"
