The properties of the tiniest particles of nature (atoms, molecules and sub-atomic particles), are described by the theory of quantum mechanics. Often, quantum mechanics is said to require a reconsideration of our rules of logic, as if “quantum logic” were something else. A theorem by particle physicist John Bell is then used to “prove” that no local, classical, deterministic theory can exist to explain quantum behaviour. However, there is reason to doubt whether that is true. Lecturer will demonstrate that systems exist that are classical and quantum mechanical at the same time. Our world of elementary particles, described by the “Standard Model”, could be such a system, but how could it disobey Bell’s theorem?
