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 create "Constructor Theory" which relies on qubits to predict which actions are possible.[1] It is interesting that man has seldom build any machine that was less efficient than one that, like the quantum Computer, manipulates qubits.
