Microscopic Reversibility

The principle of Microscopic reversibility in physics and chemistry is twofold:

  • First, it states that the microscopic detailed dynamics of particles and fields is time-reversible because the microscopic equations of motion are symmetric with respect to inversion in time (T-symmetry);
  • Second, it relates to the statistical description of the kinetics of macroscopic or mesoscopic systems as an ensemble of elementary processes: collisions, elementary transitions or reactions. For these processes, the consequence of the microscopic T-symmetry is:

    Corresponding to every individual process there is a reverse process, and in a state of equilibrium the average rate of every process is equal to the average rate of its reverse process.

He discovered that the time-reversibility of the Newtonian dynamics leads to the detailed balance for collision in equilibrium collisions are equilibrated by their reverse ... Therefore, the microscopic reversibility was used to prove the macroscopic irreversibility and convergence of ensembles of molecules to their thermodynamic equilibria ...

Famous quotes containing the word microscopic:

    The television screen, so unlike the movie screen, sharply reduced human beings, revealed them as small, trivial, flat, in two banal dimensions, drained of color. Wasn’t there something reassuring about it!—that human beings were in fact merely images of a kind registered in one another’s eyes and brains, phenomena composed of microscopic flickering dots like atoms. They were atoms—nothing more. A quick switch of the dial and they disappeared and who could lament the loss?
