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.

The concept entropy was first developed by German physicist Rudolf Clausius in the mid-nineteenth century as a thermodynamic property that predicts that certain spontaneous processes are irreversible or impossible. In statistical mechanics, entropy is formulated as a statistical property using probability theory. The statistical entropy perspective was introduced in 1870 by Austrian physicist Ludwig Boltzmann, who established a new field of physics that provided the descriptive linkage between t This item: Statistical Mechanics: Entropy, Order Parameters and Complexity (Oxford Master Series in Physics, 14… by James P.

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. in statistical mechanics, but the possibility of their existence is an argument against the quantum Boltzmann entropy .

### Entropy is a thermodynamic property just the same as pressure, volume, or temperature. Therefore, it connects the microscopic and the macroscopic world view. Boltzmann's principle is regarded as the foundation of statistical mechanics. Gibbs entropy formula. The macroscopic state of a system is characterized by a distribution on the microstates.

In thermodynamics, only differences in entropy are usually important, so it was common to fix the zero point by defining S 0 to be zero. This is the origin of the term “free energy”. 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.

grounding statistical mechanics in the Shannon notion of entropy. Probability is a quantiﬁcation of incomplete information. Entropy should not be conceived in terms of disorder, but rather as a measure on a probability distribution that characterizes the amount of missing information the distribution represents. The thermodynamic 1.1 Aim of Statistical Mechanics Statistical mechanics provides a theoretical bridge that takes you from the micro world1, to the macro world2. The chief architects of the bridge were Ludwig Eduard Boltzmann (1844 - 1906), James Clerk Maxwell(1831-1879), Josiah Willard Gibbs(1839-1903) and Albert Einstein(1879-1953). more than statistical mechanics. Information theory provides very helpful insight into the concept of entropy, which is the cornerstone of statistical mechanics.
