The Nature of Probability & The Many Worlds Interpretation of Quantum Mechanics

source: Philosophical Overdose    2015年2月21日
In this talk, David Wallace discusses the notion of probability and some of the philosophical interpretations and problems surrounding it. After distinguishing between subjective and objective probability, he goes on to discuss the possible basis of probability in the world. He then discusses how we can make sense of probability in the Many-Worlds Interpretation (MWI) of quantum mechanics. The MWI holds that quantum theory--our best current theory of physics--is correctly understood as claiming that there are many worlds that exist in parallel to our own and which branch constantly off our own. The existence of the other worlds makes it possible to make sense of physics without action-at-a-distance, objective randomness, or any strange role for "observer" or "consciousness". These lectures discuss this interpretation of quantum mechanics and what would follow from its being the correct one.
