Jeffrey Barrett presents the most comprehensive study yet of a problem that has puzzled physicists and philosophers since the 1930s. The standard theory of quantum mechanics is in one sense the most successful physical theory ever, predicting the behaviour of the basic constituents of all physical things; no other theory has ever made such accurate empirical predictions. However, if one tries to understand the theory as providing a complete and accurate framework for the description of the behaviour of all physical interactions, it becomes evident that the theory is ambiguous, or even logically inconsistent. The most notable attempt to formulate the theory so as to deal with this problem, the quantum measurement problem, was initiated by Hugh Everett III in the 1950s. Barrett gives a careful and challenging examination and evaluation of the work of Everett and those who have followed him. His informal approach, minimizing technicality, will make the book accessible and illuminating for philosophers and physicists alike. Anyone interested in the interpretation of quantum mechanics should read it.

In this book Jeffrey A. Barrett provides an introduction to the history and conceptual foundations of quantum mechanics. He begins with a description of classical mechanics and a discussion of the quantum phenomena that radically undermine our common-sense classical intuitions about how the physical world works. He then considers the physical and conceptual arguments that led to the standard von Neumann-Dirac formulation of quantum mechanics and how the standard theory explains quantum phenomena. This includes a discussion of how the theory's two dynamical laws work with the standard interpretation of states to explain determinate measurement records, quantum statistics, interference effects, entanglement, decoherence, and quantum nonlocality. A careful understanding of how the standard theory works ultimately leads to the quantum measurement problem. Barrett considers how this problem threatens the logical consistency of the standard theory and then turns to a discussion of the main proposals for resolving it. This includes collapse formulations of quantum mechanics, the various many-worlds theories, and Bohmian mechanics. In discussing alternative formulations he pays particular attention to the explanatory role played by each theory's empirical ontology and associated metaphysical commitments, and the conceptual trade-offs between theoretical options. The book is well-suited to those interested in physics and the history and philosophy of quantum mechanics.
