Wayne Myrvold (University of Western Ontario): "What is a Wavefunction?". Listen to the talk here.

Abstract:  The fact that the wavefunction of a many-body quantum mechanical system is a function on a high-dimensional configuration space, rather than our familiar 3-dimensional space or 4-dimensional spacetime, has led to the suggestion, by David Albert and others, that any realist interpretation of quantum mechanics must regard this high-dimensional space as the real arena in which events take place, something more fundamental than our familiar spacetime. In this talk, I will argue that this conclusion is not warranted.
