Covering much of the recent debate, this ambitious text provides new, decisive proof of the reality of the wave function.

An overview of the collapse theories of quantum mechanics. Written by distinguished physicists and philosophers of physics, it discusses the origin and implications of wave-function collapse, the controversies around collapse models and their ontologies, and new arguments for the reality of wave function collapse.

This is a new volume of original essays on the metaphysics of quantum mechanics. The essays address questions such as: What fundamental metaphysics is best motivated by quantum mechanics? What is the ontological status of the wave function? Does quantum mechanics support the existence of any other fundamental entities, e.g. particles? What is the nature of the fundamental space (or space-time manifold) of quantum mechanics? What is the relationship between the fundamental ontology of quantum mechanics and ordinary, macroscopic objects like tables, chairs, and persons? This collection includes a comprehensive introduction with a history of quantum mechanics and the debate over its metaphysical interpretation focusing especially on the main realist alternatives.

University Physics is a three-volume collection that meets the scope and sequence requirements for two- and three-semester calculus-based physics courses. Volume 1 covers mechanics, sound, oscillations, and waves. Volume 2 covers thermodynamics, electricity and magnetism, and Volume 3 covers optics and modern physics. This textbook emphasizes connections between between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. Frequent, strong examples focus on how to approach a problem, how to work with the equations, and how to check and generalize the result. The text and images in this textbook are grayscale.

Quantum mechanics is one of the most fundamental yet difficult subjects in physics. Nonrelativistic quantum theory is presented here in a clear and systematic fashion, integrating Born's probabilistic interpretation with Schrödinger dynamics. Basic quantum principles are illustrated with simple examples requiring no mathematics beyond linear algebra and elementary probability theory. The quantum measurement process is consistently analyzed using fundamental quantum principles without referring to measurement. These same principles are used to resolve several of the paradoxes that have long perplexed physicists, including the double slit and Schrödinger's cat. The consistent histories formalism used here was first introduced by the author, and extended by M. Gell-Mann, J. Hartle and R. Omnès. Essential for researchers yet accessible to advanced undergraduate students in physics, chemistry, mathematics, and computer science, this book is supplementary to standard textbooks. It will also be of interest to physicists and philosophers working on the foundations of quantum mechanics.

If quantum theories of the world are true-and empirical evidence suggests they are-what do they tell us about us, and the world? How should quantum theories make us reevaluate our classical conceptions of material objects? Nearly a century after the development of quantum theories, a consensus has yet to emerge. Many still wonder about what these theories may be telling us about ourselves and our place in the universe. Alyssa Ney here defends and develops a particular framework for understanding the world as it is described by quantum theories. This framework was initially suggested by Schrödinger in the 1920's and was further defended as an account of reality by two philosophers of physics in the 1990's who described it as a necessary point of view for those who argue that quantum theories are correct representations of our world. This framework is called wave function realism, which interprets quantum theories such that its central object is the quantum wave function, interpreted as a field on an extremely high-dimension space. This theory views us, and all objects, as ultimately constituted out of the wave function, and though we seem to occupy three dimensions, the fundamental spatial framework of quantum worlds consists of many more dimensions. Alyssa Ney argues for and advances this view, with the goal of making a case for how this theory how it might be applied to more other relativistic quantum theories, including quantum field theories. Her conclusion develops an account of how we as human beings might ultimately see ourselves and the objects around us as constituted out of the wave function.

This book is a tribute to the scientific legacy of GianCarlo Ghirardi, who was one of the most influential scientists in the field of modern foundations of quantum theory. In this appraisal, contributions from friends, collaborators and colleagues reflect the influence of his world of thoughts on theory, experiments and philosophy, while also offering prospects for future research in the foundations of quantum physics. The themes of the contributions revolve around the physical reality of the wave function and its notorious collapse, randomness, relativity and experiments.
