With Born's probability interpretation of the wave intensity and Heisenberg's uncertainty principle, the elements of the standard indeterministic interpretation of quantum mechanics were in place by 1930. This interpretation is often known as the Copenhagen interpretation, because Niels Bohr, who made important contributions to its formulation, ran an influential physics institute there during this period. However, many physicists, including Einstein and Schrodinger, who accepted the mathematical formulation of quantum mechanics, were uncomfortable with the Copenhagen interpretation, and criticized it. The question of the correct interpretation of the mathematical formalism has remained something of a problem up to the present.

After going through this circus, one may ask…is there anything out there that is real?

Niels Bohr says no. There is nothing actually "out there" at the quantum level. Somehow, reality emerges only in relation to the result of "measurements".
This view embraced by the majority of physicists, is called "Copenhagen Interpretation". Copenhagen Interpretation of quantum mechanics implies that quantum mechanics is as good as it gets. There is nothing really "out there", which means that detecting an electron at a certain position "creates" the position of this electron.

However this interpretation introduces a serious problem, and that is the nature of measurement. Copenhagen Interpretation assumes that measurement is what "creates" reality. But measurement is the outcome of a certain device which is nothing but a collection of atoms and molecules. So the measuring device should itself be described by a quantum mechanical wavefunction.

But if that is the case, then the device itself will not possess a definite value of all its physical qualities (including the reading of dials) until they are themselves "measured"...and so on...
But there is another view. Einstein believed that quantum mechanics, though very impressive, is not the complete thing. It gives us a imperfect picture of the quantum world, and there must be something beyond quantum mechanics which shall clarify and sharpen our present picture.
Which side are you on?
