Albert Einstein said:

Niels Bohr said:
Those who are not shocked when they first come across quantum mechanics cannot possibly have understood it.
Max Born said:
No concealed parameters can be introduced with the help of which the indeterministic description could be transformed into a deterministic one. Hence if a future theory should be deterministic, it cannot be a modification of the present one but must be essentially different.
