Time reversal-invariance/T-invariance/irreversibility/Vollmer: E.g. equations that contain a (first or higher) derivative with respect to time. - E.g. equation for motion with friction - E.g. movement under radiation damping. - E.g. Fourier equation for heat conduction. - But these are not yet the basic equations - E.g. friction consists of many shocks.
Time reversal-invariance/T-invariance/time asymmetry/asymmetry/time/time direction/Vollmer: single injury in nature: the decay of neutral kaons (K02 mesons) due to the weak interaction. - N.B.: the asymmetry occurs here also in the fundamental equation. - That is, it is the dynamic law that distinguishes between past and future and so distinguishes a time direction. - (As the only in nature).
Time reversal/Physics/Vollmer: can only mean a reversal of all the processes - E.g. electrodynamics: here, too, the currents and the magnetic fields must be reversed. - Then their equations are also T-invariant.
Time reversal/film/backwards/Vollmer: if we were in a movie and it would run backwards, we would not notice because all time arrows would be reversed.
