What is the difference between the Copenhagen Interpretation and Quantum Theory?

[rodsika]

They say Copenhagen Interpretation is not Shut Up and Calculate. So what really is Copenhagen Interpretation. What is its belief and statements? And how many percentage of physicists just focus on Quantum Theory and not care about interpretations and how many of them are into Copenhagen?

 

[ShayanJ]

as i realized(not so sure)most of the quantum physicists nowadays just "shut up and calculate" but most of those who do this,do it just because they don't care about interpretations of quantum mechanics not because of copenhagen.they leave it as a philosophical question

 

[Dickfore]

what do you mean by "interpretation of qm"?

 

[ShayanJ]

copenhagen interpretation says that there is nothing apart from humans' understanding so,e.g. according to uncertainty,a quantum particle doesn't posses position and momentum at the same time

A better exposition is given at the Stanford Encyclopedia of Philosophy's webpage: Copenhagen Interpretation.
[EDIT:]
It makes note of the fact that there really is not a unified Copenhagen interpretation. Rather one should distinguish Bohr Interp. and Heisenberg Interp.


One key excerpt:
...many physicists and philosophers see the reduction of the wave function as an important part of the Copenhagen interpretation. But Bohr never talked about the collapse of the wave packet. Nor did it make sense for him to do so because this would mean that one must understand the wave function as referring to something physically real. Bohr spoke of the mathematical formalism of quantum mechanics, including the state vector or the wave function, as a symbolic representation.
