Einstein's “quantum riddle” is the almost forgotten problem of finding the ultimate reason for the quanta. It is solved here by deduction of quantum mechanics from three general postulates, those of symmetry, correspondence, and covariance, imposed on a general probabilistic connection between states. The derivation offers a systematic approach to the quantum mathematics and its teaching by trying to “comprehend the complexity and apparent disorder of Nature in the light of a supreme order” (Einstein).
