The theoretical basis of the Coupling Model is closely related to chaos in Hamiltonian dynamical systems. In this work, the fundamental results of the Coupling Model, i.e. crossover from independent relaxation at short-times to slowed down cooperative relaxation, represented by three equations are shown to be in accord with experimental data in molecular glass formers, glass-forming or crystalline ionic conductors, and concentrated colloidal suspensions. These direct evidences together with the many successful applications of the predictions to several fields and many materials (K. L. Ngai and D. J. Plazek, Rubber Chem. Tech. Rubber Rev. 68), 376 (1995). (K. L. Ngai, J. Non-Cryst. Solids 203), 232 (1996) have led us to believe that the Coupling Model has captured the basic physics of relaxation in materials with many-body interactions.
