Irreversibility and the second law
The relation between the second law of thermodynamics and the notion of irreversibility is analysed by distinguishing three different meanings of the latter and studying how they figure in several versions of the second law. A more extensive discussion is given in [1]. 1. THREE CONCEPTS OF (IR)REVERSIBILITY Many physical theories employ a state space Γ containing all possible states s of a syst...
متن کاملIrreversibility and the second law of thermodynamics
The second law of thermodynamics has a curious status. Manymodern physicists regard it as an obsolete relic from a bygone age, while many others, even today, consider it one of the most firmly established and secure achievements of science ever accomplished. From the perspective of the foundations of physics, a particularly interesting question is its relationship with the notion of irreversibi...
متن کاملEqualities and Inequalities: Irreversibility and the Second Law of Thermodynamics at the Nanoscale
The reason we never observe violations of the second law of thermodynamics is in part a matter of statistics: When !10 degrees of freedom are involved, the odds are overwhelmingly stacked against the possibility of seeing significant deviations away from the mean behavior. As we turn our attention to smaller systems, however, statistical fluctuations become more prominent. In recent years it ha...

متن کاملThe Second Law and Informatics
A unification of thermodynamics and information theory is proposed. It is argued that similarly to the randomness due to collisions in thermal systems, the quenched randomness that exists in data files in informatics systems contributes to entropy. Therefore, it is possible to define equilibrium and to calculate temperature for informatics systems. The obtained temperature yields correctly the ...
