quantum theory, n.Definitions

Quantum theory is not only God playing dice; he sometimes even throws the dice where they cannot be seen.

Quantum theory is a field of study that 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.

Quantum theory is difficult. A person who isn't outraged on first hearing about it clearly didn't understand what had been said.
