SUMMARY:Making Sense of Probability in Everettian Quantum Mechanics
UID:20260405T194810Z-iCalPlugin-Grails@philevents-web-f5d4878dd-4s97k
TZID:America/New_York
LOCATION:1117 Cathedral of Learning\, University of Pittsburgh\, Pittsburgh\, United States\, 15260
DESCRIPTION:<p>Abstract: For some commentators on Everettian (&ldquo\;many worlds&rdquo\;) quantum mechanics\, the role of probability is the Achilles&rsquo\; heel of the interpretation. For other commentators\, the Deutsch-Wallace theorem therein (which provides a decision-theoretic derivation of quantum probabilities) is a philosophical sensation\, which is akin to deriving an ought from an is\, or alternatively\, which provides the first significant justification of Lewis&rsquo\; Principal Principle. To further complicate matters\, the two authors of the derivation appear to disagree about what it means. I am hoping to shed a little light on the debate by asking what probability means in physics in the first place. (The talk will be based in part on joint work with Gal Ben-Porath.)</p>
