Time, the Quantum---and Montevideo?

Jeremy Butterfield ( Senior Research Fellow, Trinity College, University of Cambridge )

First, I briefly review the very different conceptions of time held by three rival interpretations of quantum theory: the collapse of the wave-packet, the pilot-wave interpretation, and the Everett interpretation.

Then I turn to a much less controversial task: to expound the recent understanding of the time-energy uncertainty principle, and indeed of uncertainty principles in general, that has been established by such authors as Busch, Hilgevoord and Uffink.

Although this may at first seem a narrow topic, I point out connections to other conceptual topics about time in quantum theory. In this talk, the main such topic is the Montevideo interpretation of quantum theory, advocated by Gambini, Pullin and co-authors.
