Modern knowledge about the structure of the microworld turned out to be inferior due to two fundamental errors made as far back as the century before last when interpreting the results of the experiments of Oersted (1821) and Fizeau (1851). Refusing, due to these errors, to take into account the ether and magnetic interactions between microobjects, physics was not able to use Newton's “classical” formalism to study the microworld and turned to a quantum worldview. Despite the stream of self-praise and Nobel prizes, quantum theory failed to achieve a full, detailed understanding of the structure of the atomic nucleus, unexcited atom, photon, excited atom, electron, neutron, proton, ... In 1979, experimental evidence was published in the Central Russian Physical Academic Journal of the absence of undivided energy quanta in Nature [1]. The theory of nonlinear oscillations, operating on the "classical" methods of Newton, tells how it corrects the mentioned physical misunderstandings..
