ABSTRACT
Niels Bohr had the following to say about quantum mechanics: Those who are not shocked when they first come across quantum mechanics cannot possibly have understood it. Richard Feynman was of the opinion that no one understands quantum mechanics: I think it is safe to say that no one understands quantum mechanics. Do not keep saying to yourself, if you can possibly avoid it, “But how can it be like that?” because you will get “down the drain” into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.
