::::::::: I think a definition of thermodynamic entropy is too much for an introduction section and should go in the explanation section.[[User:PAR|PAR]] ([[User talk:PAR|talk]]) 20:36, 19 December 2020 (UTC)
::::::::::I tend to agree, but I think we need to attend to Editor Chetvorno's concern. I like to distinguish between a lead and a section in the body of the article entitled 'Introduction'. [[User:Chjoaygame|Chjoaygame]] ([[User talk:Chjoaygame|talk]]) 20:49, 19 December 2020 (UTC)
:::::::Regarding my statement "Any state, disequilibrium or not, has a macrostate, and an associated set of microstates, .". Yes, I have to amend that statement. It holds for cases where, e.g. the pressure and temperature for each type of particle are defined functions of space and time ([[local thermodynamic equilibrium]]). Now entropy density can be defined and total entropy can be said to decrease, assuming we can talk about the rates of energy and entropy tranfer between two equilibrated systems in contact and almost in equilibrium with each other. But the question is, how does this apply to an introductory article? Can we use the words "Entropy does not increase indefinitely" as an introductory statement, knowing that it is flawed? I think the verbal gymnastics we have to go thru to keep things rigorous but simple are almost overwhelming in this case. [[User:PAR|PAR]] ([[User talk:PAR|talk]]) 07:36, 19 December 2020 (UTC)
