  • And this is the gateway to almost all of modern quantum mechanics and statistical mechanics, quantum statistical mechanics.
  • physics and statistical mechanics
  • particle systems of statistical mechanics
  • models in statistical mechanics

So that that's one thing which comes out of statistical mechanics if you take it too seriously.

Morphology

statistical + mechanics

The phrase is compositionally built — 'statistical' modifies 'mechanics' so it indicates a branch of mechanics that uses statistics, a relation that a B1 learner who knows both words can grasp. However, the full technical sense (ensembles, probabilistic laws for many-particle systems) is specialized and not predictable from the constituents alone, so the transparency is only partial.

Etymology

Statistical mechanics comes from two simple ideas: statistical (about numbers and chance) and mechanics (how parts move). It pictures a machine made of many tiny parts that we cannot watch one by one, so scientists use statistics to understand the whole — that's why it means 'the study of many particles and their behavior'.
