Examples
-
Some general methods for deriving such equations are the master equation approach and an approach that relies upon coarse-graining the phase space of points representing the micro-states of the system into finite cells and assuming fixed transition probabilities from cell to cell (Markov assumption).

-
How we do the coarse-graining to define which microstates are macroscopically equivalent is a classic question.

There is no such natural tendency, since no matter what coarse-graining you choose, there is an equal number of trajectories that decrease their entropy and trajectories that increase their entropy.

Just a word on the coarse-graining Steve M. refers to above.
-
(Where the entropy of a state is defined by its macroscopic equivalence class under the coarse-graining, which is a perfectly sensible thing to do.)

It is a large and manysided subject, connected with locality, relativity, coarse-graining and enthropy, and so on.

The foundations of statistical physics may today be characterized as a battlefield between a dozen or so different schools, each firmly dug into their own trenches, e.g., ergodic theory, coarse-graining
