Thermodynamic and Differential Entropy under a Change of Variables

Thermodynamic and Differential Entropy under a Change of Variables

The differential Shannon entropy of information theory can change under a change of variables (coordinates), but the thermodynamic entropy of a physical system must be invariant under such a change. This difference is puzzling, because the Shannon and Gibbs entropies have the same functional form. W...
