Interpreting the Quantum World

Description

This is a book about the interpretation of quantum mechanics, in particular about how to resolve the measurement problem introduced by the orthodox interpretation of the theory. The heart of the book is a new result that shows how to construct all possible 'no collapse' interpretations, subject to certain natural constraints and the limitations imposed by the hidden variable theorems. From this perspective one sees precisely where things have gone awry and what the options are. Various interpretations, including Bohm's causal interpretation, Bohr's complementarity interpretation, and the modal interpretation are shown to be special cases of this result, for different choices of a 'preferred' observable. A feature of the book is a novel treatment of the main hidden variable theorems, and an extended critique of contemporary 'decoherence' theories of measurement. The discussion is self-contained and organized so that the technical portions may be skipped without losing the argument. This book will be of interest to advanced undergraduates and graduate students in philosophy of science, physics, and mathematics with an interest in foundational problems in quantum physics. General readers with some technical sophistication will also find the book of value.
