![]() We will examine the collision of two atoms and show that if their velocities are reversed at some time after the collision, it is highly improbable that they will retrace their paths. And this is correct.īut microscopic reversibility, while still true when considering averages over time, should not be confused with the time reversibility of a specific individual collision between particles. What "detailed balancing" means is that in thermodynamic equilibrium, the number of forward reactions is exactly balanced by the number of reverse reactions. Quantum events also approach classical behavior in the limit of large quantum numbers, which Niels Bohr called the "correspondence principle." In fact microscopic reversibility is an assumption that is only statistically valid in the same limits as any " quantum to classical transition." This is the limit when the number of particles is large enough that we can average over quantum effects. It is mistakenly thought to be the basis for the "detailed balancing" of chemical reactions in thermodynamic equilibrium. ![]() ![]() Microscopic time reversibility is one of the foundational assumptions of both classical mechanics and quantum mechanics. Information physics claims that microscopic reversibility is actually extremely unlikely and that the intrinsic path information in particles needed to reduce entropy is erased by matter-radiation interactions or by internal quantum transitions in the colliding atoms considered as a "quasi"-molecule.
