Demystifying Quantum Mechanics

Why does such a successful theory like Quantum Mechanics have so many mysteries? The history of this is replete with dubious interpretations and controversies, yet knowledge its predictions, however, contributed to the amazing technological revolution last hundred years. In very beginning Einstein pointed out that there was something missing, due contradictions relativity theory. So, even though explains all nanoscale physical phenomena, were attempts find way “complete” it, e.g. hidden-variable theories. paper, we discuss some those enigmas, special attention concepts reality imposed by quantum mechanics, role observer, prediction limits, definition collapse, how deal correlated states (the basic strategy for computers teleportation). That discussion carried within framework accepting in fact nothing important rather are just restricted limitations mechanics. mysteries thus explained proper interpretation limitations, which achieved introducing two rules Copenhagen paradigm.
