As a followup to our series on thermodynamics, the briefest of introductions to one of the most fascinating and beautiful areas of physics - Statistical Mechanics.

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.

In this Perspective, we describe the impact that fundamental concepts from statistical mechanics, notably entropy, stochastic processes and critical phenomena, are having on single-cell data analysis.

In each generation, scientists 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.

Find an expression for the entropy per spin \(s(e, H)\) as a function of the energy per spin e and magnetic field \(H\) in the thermodynamic limit.

Although entropy originated from statistical mechanics, within physics, it is more generally applicable and better understood from the perspective of information theory.

Suppose the number of such micro- Before statistical mechanics was developed, the zero point of entropy was considered arbitrary. 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”.
