Detonation science has been annoyed for a long time with the argument that the entropy has a minimum at the process end of detonation models. Neglecting thermodynamics, Newton mechanics that is invariant for the substitution t→-t may create thermodynamic mistake in describing detonation phenomena. The order assumption in CJ and ZND models, which considers all particles of detonation products march orderly in one direction, implies low entropy and thermodynamic non-equilibrium. Overstating CJ and ZND model, or even treating them as the objective reality of detonation process itself hinders the development of detonation science.
