This result holds for any pair of incompatible observables, since the commutator of the corresponding operators is non-zero. It was introduced in a paper on the interpretation of matrix mechanics which included a thought experiment with a gamma-ray microscope. Part of the Copenhagen interpretation of quantum mechanics, it weakens causality since perfect information is impossible. For 10 points—name this principle stating the a subatomic particle's position and momentum cannot be simultaneously and precisely known.
