Question

what is the theme of thermodynamic

Answer 1

Thermodynamics started as the study of heat engines, but applies to all processes in the universe, including those of chemistry and, crucially, the workings of life at every level. So, though this theme concerns the thermodynamics of living processes, we illustrate it with, perhaps the quintessence of thermodynamics, the formation of and working of stars, where the chemical elements used by all known life are created and the source of energy for very nearly all life on earth (we mean our nearest star, of course). The statistical mechanics interpretation of thermodynamics has both inspired and confused the use of information theory in biology (and other fields beyond physics), most notably regarding entropy. Here we try to convey a clear understanding of both thermodynamics and statistical mechanics interpretations of living processes in a way that supports the integrated description of life as an information-process, at all levels from atoms to the global ecosystem.
