Re: Entropy



Leigh,

Did you mean http://www.av8n.com/physics/thermo-laws.htm#sec-entropy instead
of http://www.av8n.com/physics/twelve-coins.htm

The first site contains the entropy explanation, the second 12-coin page
merely uses entropy as part of an explanation of the solution to the 12-coin
puzzle.

| One does not *require* a definition of entropy to define
