Accessible to readers with little background in physics or philosophy, this book allows the reader to wrestle with the metaphysical and conceptual problems that drove innovation in physics, from nineteenth-century electromagnetic field theory through relativity and quantum mechanics. Among the topics treated are locality, causality, and scientific explanation; relativity, energy, mass, and the reality of fields; and quantum metaphysics.

The book's engaging, non-technical style makes it ideal for those who want to go beyond the equations and discover what physics reveals about reality.
