why trillions of jittering atoms agree to act like a single calm law.
means the branch of physics that derives heat, pressure, and entropy from averaging the chaotic motion of huge numbers of particles.
from born in the 1870s-1900s from boltzmann and gibbs, who dared to explain thermodynamics not with mysterious fluid heat but with atoms nobody had yet proven existed.
