I would have expected arguments about entropy like those that started this
thread would have been settled long ago. For an indication why this did not
happen look for this article on the Internet: "The Gibbs Paradox" by E.T
Jaynes. Another reason might be what happened to these people (according to
a book called Decoding Reality): Boltzmann (suicide), Nietzsche (committed
to mental institution), Ehrenfest (suicide), & Mayer (committed to mental
institution).
Perhaps the time has come for physicists to use different terms for types of
entropy that are only sometime numerically equal. I suggest tentropy
(calculated from thermodynamics), sentropy (classical statistical mechanics)
and quentropy (quantum mechanics).
Then there is mentropy (entropy means whatever a textbook or journal article
author wants it to mean).
Any opinions on this: In his Journal of Statistical Physics article is
Svendsen supporting a "one size (formula) fits all" view ("by defining the
entropy as the log of the probability distribution. both classical and
quantum statistical mechanics can- be treated consistently.") or is he
limiting the inclusion of N! in the entropy formula to ideal gases
("Different experimental conditions produce different expressions for the
entropy)?
