"I think I can safely say that nobody understands quantum mechanics." #Richard Feynman# Basing his discussion on a small number of conceptually simple models (the two-level atom, the two-slit interferometer), the author addresses a number of conceptually interesting questions concerning the puzzles of quantum mechanics. Though the phenomena arising from quantum interference are central, he maintains that they are not the only mystery in quantum mechanics: the deep connection between spin and the statistics of identical particles, the "ghostly" long-range effects that correlated particles exert on each other, and the perplexing role of topology in the interactions of charged particles and electromagnetic fields, are all conundrums yet to be understood.

Approximately 10 years have passed since the publication of And Yet 1 It Moves: Strange Systems and Subtle Questions in Physics. During this time, the book has done very well, being received favorably by both readers and reviewers. The exhaustion of the last printing has given me the opportunity to make revisions. The present volume, updated and expanded by three new chapters containing a total of 17 additional essays on a wide range of questions that I have explored in quantum mechanics, nuclear physics, thermodynamics, general relativity, and astrophysics, has been given a new title to re?ect the broad thematic coverage and a new publisher (Springer-Verlag). The Introduction (The Fire Within) that follows, based on the preface to the original edition, explains fully the purpose and content of this book. I wish to note brie?y here, however, that time and the advance of physics have not dulled the scienti?c relevance of any of the essays. This book, like its predecessor, is not intended to be a popularization, a textbook, or a monograph of any ?eld of physics. Rather, it is a p- sonal account of the scienti?c underpinnings, motivations, lessons, and rami?cations of some of the many fundamental physical problems that have engaged me throughout my career to the present. These are essays that anyone with an interest in contemporary physics can read, although it is certainly the case that the more serious the interest, the more meaningful will be the essays.

Originally published in 1993, this book of essays is a largely nonmathematical account of some of the strange behaviour, both classical and quantum, exhibited by moving particles, fluids and waves. Drawn from the author's researches in quantum mechanics, atomic and nuclear physics, electromagnetism and optics, gravity, thermodynamics, and the physics of fluids, the essays describe different physical systems whose behaviour provokes surprise and challenges the imagination. There are strange processes for which no visualisable mechanism can be given; processes that seem to violate fundamental physical laws, but which in reality do not; processes that are superficially well understood, yet turn out to be subtly devious. The essays address questions or controversies from whose resolution emerge lessons of general significance regarding the mystery and fascination of motion. Anyone with a basic physics background or with an interest in the fundamental questions of physics will find this book of use.

Mark Silverman has seen light perform many wonders. From the marvel of seeing inside cloudy liquids as a result of his own cutting-edge research to reproducing and examining an unusual diffraction pattern first witnessed by Isaac Newton 300 years ago, he has studied aspects of light that have inspired and puzzled humans for hundreds of years. In this book, he draws on his many experiences as an optical and atomic physicist--and on his consummate skills as a teacher and writer about the mysteries of physics--to present a remarkable tour of the world of light. He explores theoretical, experimental, and historical themes, showing a keen eye for curious and neglected corners of the study of light and a fascination with the human side of scientific discovery. In the course of the book, he covers such questions as how it is possible to achieve magnifications of a millionfold without a single lens or mirror. He asks what all living things have in common that might one day allow the development of a "life-form scanner" like the one in Star Trek. He considers whether more light can reflect from a surface than strikes it, and explores the origin of the strange hyperpolic diffraction pattern Newton originally produced with sunlight and knives. Silverman also discusses his new and ground-breaking experiments to see into murky substances such as fog or blood--a finding with potential applications as diverse as noninvasive medical testing and remote sensing of the environment. His wide-ranging reflections cover virtually all elements of physical optics, including propagation, reflection, refraction, diffraction, interference, polarization, and scattering. Throughout, Silverman makes extensive reference to both modern research and the original works of giants such as Newton, Fresnel, and Maxwell. In a more personal section about physics and learning, Silverman argues for self-directed learning and discusses the central importance of stimulating scientific curiosity in students. Waves and Grains will encourage a spirit of wonder and inquiry in anyone with scientific interests.

Based around a series of real-life scenarios, this engaging introduction to statistical reasoning will teach you how to apply powerful statistical, qualitative and probabilistic tools in a technical context. From analysis of electricity bills, baseball statistics, and stock market fluctuations, through to profound questions about physics of fermions and bosons, decaying nuclei, and climate change, each chapter introduces relevant physical, statistical and mathematical principles step-by-step in an engaging narrative style, helping to develop practical proficiency in the use of probability and statistical reasoning. With numerous illustrations making it easy to focus on the most important information, this insightful book is perfect for students and researchers of any discipline interested in the interwoven tapestry of probability, statistics, and physics.

Coherence, entanglement, and interference arise from quantum superposition, the most distinctive and puzzling feature of quantum physics. Silverman, whose extensive experimental and theoretical work has helped elucidate these processes, presents a clear and engaging discussion of the role of quantum superposition in diverse quantum phenomena such as the wavelike nature of particle propagation, indistinguishability of identical particles, nonlocal interactions of correlated particles, topological effects of magnetic fields, and chiral asymmetry in nature. He also examines how macroscopic quantum coherence may be able to extricate physics from its most challenging quandary, the collapse of a massive degenerate star to a singularity in space in which the laws of physics break down. Explained by a physicist with a concern for clarity and experimental achievability, the extraordinary nature of quantum superposition will fascinate the reader not only for its apparent strangeness, but also for its comprehensibility.
