The interpretation of some of theoretical foundations of physics will be changed. Planck’s constant is known to be one of such foundations, which serves as a basis of quantum mechanics. Let us consider how a refinement of interpretation of the physical essence of this constant allows to make a theoretical penetration into the depth of electromagnetic structure of the electron and to connect this structure with the results of the experiment. Difficulties encountered in explaining the radiation of the theoretical black body were overcome in December 1900 when Max Planck supposed that energy, p E, in EM form is not emitted continuously, but discrete amounts Planck named quanta;that is: Ep = hn, where n – frequency of EM radiation;h – a universal constant later called Planck’s constant.
