Statistical Mechanics
Connect the motion of tiny particles to the behavior of matter you can feel.
microstates behind a temperatureS = kᵦ ln Ω
many microstates → one macrostate
The dots are not a molecular simulation. They make the statistical move visible: a macroscopic variable compresses information about a huge number of microscopic arrangements.

A macrostate can be realized by many microstates. The overwhelmingly numerous arrangements are why equilibrium is the most likely large-scale observation.
