Maxwell's demon is a thought experiment that appears to disprove the second law of thermodynamics. It was proposed by the physicist James Clerk Maxwell in 1867. [ 1 ] In his first letter, Maxwell referred to the entity as a "finite being" or a "being who can play a game of skill with the molecules".
Roger Joseph Boscovich developed a more physical version of the same thought experiment, known as Boscovich's demon, based on position, velocity, direction and center of mass. Maxwell's demon – Hypothetical being that can distinguish between fast and slow moving molecules. If this demon only let fast moving molecules through a trapdoor to a ...
When the demon is reset i.e. when the ligand is released, the information is erased, energy is dissipated and entropy increases obeying the second law of thermodynamics. [1] The difference between biological molecular demons and the thought experiment of Maxwell's demon is the latter's apparent violation of the second law. [2] [3]
It involved a long-standing puzzle in the philosophy of thermal and statistical physics known as Maxwell's demon, a thought experiment originated by the physicist James Clerk Maxwell. The problem was thought to be insoluble, but in tackling it Szilard recognized the connection between thermodynamics and information theory.
A thought experiment is a hypothetical situation in which a hypothesis, theory, [a] ... Maxwell's demon (thermodynamics) 1871; Mermin's device (quantum mechanics)
The point of a thought experiment is usually to clarify the properties of a model or theory and to clarify hidden assumptions. Therefore, getting the correct result is often less important than understanding how that result comes about. Maxwell's demon seems to show an inconsistency between elementary mechanics and the laws of thermodynamics.
Hulu's new doc, 'Victoria's Secret: Angels and Demons' delves into CEO Les Wexner's relationship with Jeffrey Epstein. What to know about Epstein's girlfriends.
A physical thought experiment demonstrating how just the possession of information might in principle have thermodynamic consequences was established in 1929 by Leó Szilárd, in a refinement of the famous Maxwell's demon scenario [5] (and a reversal of the Joule expansion thought experiment). Consider Maxwell's set-up, but with only a single ...
