Quantum mechanics is an extremely powerful and successful theory in predicting the behaviour of the microscopic. However, there are many dilemmas in trying to reconcile a probabilistic theory of physics. Does God in fact play with dice? A century after its development, physicists, mathematicians, and philosophers are still asking what is the proper way to interpret quantum mechanics. Does such an interpretation exist? In this seminar, we will discuss Hugh Everett’s “many-worlds” interpretation (aka, Theory of the universal wavefunction). We will see that in its formulation, many-worlds actually makes quantum mechanics deterministic and even removes the so-called measurement problem, which pertains to the perceived collapse of the wavefunction.
