After unsuccessful arguments with N.Bohr about the incompleteness of the non-relativistic electron (NE) created by Schrödinger in wave quantum mechanics (WQM), Einstein said: " I am more and more inclined do think that extra-spatial structures are necessary for the further development of physics ". And the extra-spatial structures predicted by Einstein had to be constants, since only constants were independent of the space-time continuum. Therefore, it was necessary to find an answer to the question: " How can constants be used as extra-spatial structures for the further development of physics?" The answer this question arose naturally when we managed to find out that Planck’s constant and other constants associated with it are the proper corpuscular-wave (CW) quantities of microparticles. At the same time, the newly discovered extra-spatial CW quantities of microparticles, being constants, turned out to be extra-spatial structures in relation to the Euclidean, Minkowski and Klein-Gordon spaces. In addition it turned out that our newly discovered extra-spatial CW quantities of microparticles inside the space of Euclidean, Minkowski and Klein-Gordon appear in the form of corpuscular, mixed and wave quantities of microparticles that are generally known to this day. Moreover, the emergence within spatial corpuscular quantities from extra-spatial CW quantities made it possible to understand that the corpuscular quantities of Newton’s corpuscular classical mechanics (CCM), which were considered the principles of physics, are not in fact the principles of physics. It turned out that the WQM of a NE created by Schrödinger is an incomplete version of the corpuscular-wave mechanics (CWM) of a NE. No matter discover the extra-spatial predicted by Einstein necessary for the further development of physics in the form of extra-spatial proper CW quantities and the CWM of real objects of Nature.
