Computing heat capacities in Bohmian Mechanics
(06-01-2016, 02:15 AM)user7348 Wrote: I'm not a physicist, but I used "phase space" because Lubos used it in the same context:

the entropy of an atom (the logarithm of the volume of the phase space of states that are accessible at the thermal equilibrium) -- LM
This is, indeed, the definition of entropy in classical Hamiltonian physics, where we have a phase space.

And this seems indeed to be the point where Lubos makes the error. He presents dBB theory as a sort of classical theory, thus, one would have to apply formulas known from classical thermodynamics. He seems to ignore that these formulas are not a priori postulates but follow from Hamiltonian physics.

Just to add a warning: The foundations of thermodynamics are a domain were misunderstandings and confusion are quite common even among professionals, so that it really difficult for laymen to understand it.
