"The intent of the Einstein-Podolsky-Rosen paper was to show that quantum mechanics... could not be the final word regarding the physics of the microcosmos. ...they wanted to show that every particle does possess a definite position and a definite velocity at any given instant of time, and thus they wanted to conclude that the uncertainty principle reveals a fundamental limitation of the quantum mechanical approach. ...quantum mechanics provides only a partial description of the universe. ...an incomplete theory of physical reality and, perhaps, merely a stepping-stone toward a deeper framework waiting to be discovered."
