There are many microscopic states fq i;p igconsistent with (N;V;E). Suppose the number of such micro- Actually, this whole field is called 'statistical mechanics'. So, when you view at the situation statistically, it is possible that the entropy of a system can come down. But the probability of this outcome is so bleak that we often neglect it like it does not even exist. The most important quantityin statistical mechanics iscalled “en-tropy,” which we label by S. People sometimes say that entropy is a measureofthe“disorder” ofasystem,butIdon’tthinkthisagoodway tothinkaboutit.
Statistical mechanics is our tool for deriving the laws that emerge from complex systems. Sethna's text distills the subject to be accessible to those in all realms of science and engineering -- avoiding extensive use of quantum mechanics, thermodynamics, and molecular physics. In physics however, entropy plays a much more central role, and forms the basics of statistical mechanics. While entropy was coined in 1870, and later modified in 1902 by Gibbs, it was not viewed as essential to statistical mechanics, until Shannon’s famous paper. The second law has been used to define entropy. But once we have introduced the notion of entropy, the second law is equivalent to the statement that entropy tends to increase. For any process, we can say that \[\frac{dS}{T} ≥ 0\] We can actually see that this is equivalent to the Kelvin statement of the second law as follows.

In the resulting "subjective statistical mechanics," the usual rules are thus justified F.D. distributions of statistical mechanics by using maximum entropy principle. Some proofs of B.E. & F.D. distributions are shown, and at the end some new The prevailing beliefs in the scientific and engineering literature are that: (i) thermodynamics is explained and justified by statistical mechanics; (ii) entropy is a 31 Dec 2020 4.7 Statistical Ensembles from Maximum Entropy . . . .
The entropy plays a central role in this theory because it is a unique function for each system that determines all thermodynamic information. The calculation of the form of the entropy lies in the microscopic description given by statistical mechanics. Statistical Mechanics: Entropy, Order Parameters and Complexity. James Sethna.

A rigorous interpretation is provided by the discipline of statistical mechanics, which derives a precise expression for entropy based on the behavior of macroscopic amounts of microscopic particles. Suppose we focus our attention on a particular macroscopic equilibrium state.
