The very nature of the quantum theory ... forces us to regard the space-time coordination and the claim of causality, the union of which characterizes the classical theories, as complementary but exclusive features of the description, symbolizing the idealization of observation and description, respectively.

[T]he atoms or elementary particles themselves are not real; they form a world of potentialities or possibilities rather than one of things or facts.

In 1924, I became a Dozent in Gottingen and worked out the quantum mechanics during a holiday stay on Heligoland.

Classical mechanics gave us a deterministic view of the world. Quantum mechanics, conversely, gives us a probabilistic view instead. According to Newton, if you know the cause af an event, you can predict the outcome. According to M.Born, you can only predict how likely that outcome will be.
