## Full Title or Meme

The entropy of isolated systems left to spontaneous evolution cannot decrease, as they always arrive at a state of thermodynamic equilibrium where the entropy is highest at the given internal energy.

## Context

- The original purpose of the
**Second Law of Thermodynamics**was by Carnot in the determination of the maximum efficiency of steam engines. - Boltzmann argued that the Second Law is statistical in nature and stated that while systems with increasing are possible, their occurrence could be assigned an
*extremely*low probability. - Boltzmann's solution in terms of large ensembles of point particles has become the field of Statistical Physics, which is the only physical law that is not deterministic.
- In communications and information sciences, the
**Second Law of Thermodynamics**is typically addressed as a statement about information. - From computer science Rolf Landauer used information theory to determine that while reversible computation was possible, the erasure of information always resulted in loss of energy.
- Now physicists are using Landauer's results to
