As a consequence, entropy is essentially an objective quantity, and the context fades into the background. But even between (micro-/grand-) canonical ensembles, there are subtle differences between what macroscopic variables are significant, hence difference between the entropies, which vanish in the thermodynamic limit. -- ---------------------------------------------------------------------------- Prof Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Professor of Mathematics [email protected] University of New South Wales http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
