متن کاملMendel's demon
on the shelves of any evolutionary biologist or student of the subject and you are likely to see a textbook by Mark Ridley. But Ridley, formerly at Emory University in Atlanta, and now in Oxford, has had another book in his mind for quite some time. He believes there are some ideas sparked by the Austrian monk, Gregor Mendel, that are of broader interest and has set out to explore some of them ...
متن کاملThe Maxwell demon in the osmotic membrane
The dielectric with index of refraction n is inserted in the Planck blackbody. The spectral formula for photons in such dielectric medium and the equation for the temperature of photons is derived. The new equation is solved for the constant index of refraction. The photon flow initiates the osmotic pressure of he Debye phonons. The dielectric crystal surface works as the osmotic membrane with ...
متن کاملMaxwell’s Demon
This problem is prob. 2 of [1]. One of the earliest conceptual “supercomputers” was Maxwell’s Demon [2], who uses intelligence in sorting molecules to appear to evade the Second Law of Thermodynamics. To place the demon in a computational context, consider a computer “memory” that consists of a set of boxes (bits), each of volume V and each containing a single molecule. A (re)movable partition ...
متن کاملThe Demon in a Vacuum Tube
In the present paper, several issues concerning the second law of thermodynamics, Maxwell’s demon and Landauer’s principle are dealt with. I argue that if the demon and the system on which it operates without dissipation of external energy are made of atoms and molecules (gas, liquid or solid) in thermal equilibrium (whose behaviour is described by a canonical distribution), then the unavoidabl...
