Today Quantum mechanics is "non-mechanical" theory. Why? Because Classic Mechanics deals with objects that have real physical parameters : size, volume, geometrical forms and QM doesn't have real particles. In QM we are missed geometrical form of quantum particle. Real quantum particle cannot be a "point". Real quantum particle cannot be a "firm golf-ball" ( forbidden by SRT) Using models like "point-particle" or "firm golf-ball", we cannot describe QM in mechanical terms. One can adopt QM "visually" only understanding the mechanical model of quantum particle (!) . . . .. . and then giving forces to it . . . . . . . . see how this model works mechanically . . . . . . . and what is result of its mechanical behavior. Once again. QM is very practical theory and therefore it cannot be paradoxical. Its interpretation must be realistic. The best realistic way is to observe quantum particle as a simple mechanical object which somehow can produce quantum electrical (EM) effects. == Einstein wrote: "Some physicists, among whom I am myself can not believe that we should once and for all abandon the idea of direct images of physical reality in space and time, or that we should agree with the opinion that a phenomenon in nature like a game case." /Einstein/ How is it possible to see / to image geometrical form of quantum particle "direct"? In my opinion there is only one way to see / to image geometrical form of quantum particle "direct": we need to observe quantum particle in its own-native reference frame zero vacuum T=0K. ==..
