*Statistical Mechanics is able to give us an explanation of WHY the second
law says entropy *almost* never decreases. There are astronomically more
disorderly states than orderly states but they are not infinitely more, and
that's what would be required to move from overwhelmingly unlikely to
absolutely impossible.  *
