**E**[x,y,z,t]

The function,

**E**[x,y,z,t], is a macrostate. Corrresponding to it are all the ways the charge in the system could be arranged (

**p**[x,y,z,t])so as to produce this macrostate. The set of

**p**[x,y,z,t]s corresponding to a given

**E**[x,y,z,t] are called microstates.

QM places restrictions on the number of distinct pairs of (momentum, position) that a particle can have. Therefore, in the EM system described above, there are a finite number of microstates corresponding to each macrostate.

Since the entropy is essentially the number of microstates corresponding to the current macrostate, is it true that the entropy of an electrodynamic system tends to increase?

This would be a most fabulous result.
