Title: " Do We Understand Quantum Mechanics?
"
Abstract:
Richard Feynman once stated that "if you think you understand quantum theory, you don't understand it." Does that mean, that the theory is somehow impossible to understand - in principle? In my talk, I will propose a new definition for what 'scientific understanding' means. Afterwards I will take a look at three famous interpretations of quantum mechanics: The Kopenhagen Interpretation, An American Philosopher's (Tim Maudlin's) view and the Theory of David Bohm. While they all refer to the same mathematical formalism - and are therefore only a 'matter of taste' for physicists - one of them will turn out be objectively better by my definition of understanding. Despite being a philosophical result, this could be relevant for physics, if it still is a science which aims at increasing our understanding of the world around us.
