Gibbs Definition and 203 Threads

Hi all. About Gibbs' paradox (with the mixture entropy for ideal gases): Is the paradox a Thermodynamic paradox? Because what's bothering me is that in Thermodynamics, the entropy is determined up to a "constant", allegedly, \[ S_0 \] , which in my opinion is dependent of \[ N \] ...

What I have not seen in books about the Gibbs paradox is that it doesn't exist if we make the Gibbs correction at the logarithm of the Z function, not at the Z function itself, in that way: \ln Z_{i} - \ln N_{i} ! where N_{i} is the number of identical particles of class i, where there...

Hi all, hopefully someone can help me out here: I'm looking at the Gibbs' method for orbit determination, and I'm losing the conceptual picture in the vector calculations. I have no problems seeing how D and N point in the W direction (PQW coordinate system), but I'll be damned if I can...
