Proper noun
the Copenhagen interpretation
A collection of views about the meaning of quantum mechanics principally attributed to Niels Bohr and Werner Heisenberg, including the idea that quantum mechanics is intrinsically indeterministic, with probabilities calculated using the Born rule, and the principle of complementarity, which states that objects have certain pairs of complementary properties which cannot all be observed or measured simultaneously.
If I were forced to sum up in one sentence what the Copenhagen interpretation says to me, it would be 'Shut up and calculate! David Mermin
So the old Copenhagen interpretation needs to be generalized, needs to be replaced by something that can be used for the whole universe, and can be used also in cases where there is plenty of individuality and history. Murray Gell-Mann
According to my attempts to understand them, reality is systematically denied in the Copenhagen interpretation in order to circumvent consistency problems (such as "Is the electron really a wave or a particle?”). If there is no reality, one does not need a consistent description! H. Dieter Zeh
According to the Copenhagen interpretation of quantum mechanics, there is no fundamental reality that the quantum state describes, just a prescription for calculating experimental results. Source: Internet
Acceptance among physicists Throughout much of the twentieth century the Copenhagen interpretation had overwhelming acceptance among physicists. Source: Internet
According to the Copenhagen interpretation of quantum mechanics, the quantum state of the system collapses into state I. The quantum state determines the probable outcomes of any measurement performed on the system. Source: Internet
