Entropy has a unique expression for each context cropping up on a regular basis. Isn't that so? I thought the driver behind that was each context has some distinguishing feature that changes the intuitive approach to thinking about entropy. Like entropy for Chemistry. The mechanism tends to be chemical reactions, and the intuitive sequencing for that has the distinguishing feature of being scale invariant, more or less. So the intuitive direction is always to the maximum scale with the same bounds. So it tends to be about the law of finding the shortest path to the equilibrium.t How the approach is exponential. Because chemistry follows the same sequence at the same rate for the same initial conditions, the same for a 10m cubed section of...the surface of a planet or whatever...as the same structure up scale to the whole planet. Is that wrong? So anyway, entropy and disorder and 'states', thermodynamics, time (scale free means time invariant more or less). None of that gets mentioned at all in the most common reference. I appreciate nothing I say contradicts what you say...it's just that I feel that this is a really fundamental character to entropy. No one feels the same way it seems....I have mentioned this before but I don't think I ever get a reply. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
