A Change in Paradigm: A Realistic Copenhagen Interpretation (Realism Without Hidden Variables)

Quantum mechanics has basically two types of interpretation; an epistemological and an ontological one (1). The epistemological interpretation holds that the statements of quantum mechanics are related to our knowledge, henceforth the probabilistic character, the uncertainty relations and the reduction of the wave packet talk about the boundaries and incompleteness of our theory. On the other hand, the ontological interpretation says that the predicates of quantum mechanics are predicates about reality uncertainty relations express the joint nonexistence of some physical quantities, quantum jumps show the real discontinuity of certain physical processes, and so on.
