FISICA E REALISMO

The question of realism in physics is addressed by following the path laid out by Einstein and Bell. After an exposition of the problem of the completeness of quantum mechanics and a discussion of some aspects of the debate between Einstein and Bohr, we outline what are the requirements of a formulation of quantum mechanics that is not based on such vague and imprecise notions as “ measurement†or “ observer.†Finally , we show that a physical theory that describes “stuff†in the space that evolves over time makes transparent the relationship between theory and empirical reality. The conclusion has a Kantian flavor.
