Unable to correctly interpret the results of the experiments of Oersted (1821) and Fizeau (1851), due to insufficient scientific preparation, physics excluded ether and magnetic interactions between microobjects from the paradigm of the microworld theory. Failing, because of this, to apply the "classical" Newton methods to identify atomic structures, she was forced to turn to the false idea of the existence of indivisible energy quanta. This, in turn, led to the emergence of false concepts of positronium collapse and annihilation, mass and energy equivalence, ..., and more than half a century of fundamental failures in the neutrino and thermonuclear problems. Having restored scientific justice by taking into account the ether and returning to magnetism its objective role in the material World, the theory of nonlinear oscillations began to develop the “classical” theory of the microworld from mathematical models of unexcited atoms, from the structures of photons and excited atoms.
