Maxwell’s Demon, Szilard Engine and Landauer Principle

The second law of thermodynamics is probabilistic in nature. Its formulation requires that the state a system be described by probability distribution. A natural question, thereby, arises as to whether prior knowledge about affects law. This question has now been nurtured for over century, and it was incepted C Maxwell through his famous thought experiment wherein comes idea Maxwell’s demon. next important step this direction provided L Szilard, who demonstrated theoretical model an information engine incorporating final led inter-linkage theory Landauer’s principle erasure established fact physical. Here, we will present overview these three major works laid foundations thermodynamics.
