This volume tries to continue a tradition of reviews of the contemporary research on the foundations of modern physics begun by the volume on the Einstein Podolsky-Rosen paradox that appeared a few years ago. (I) Its publication coin cides with the hundredth anniversary of de Broglie's birth (1892), a very welcome superposition, given the lasting influence of the Einstein-de Broglie conception of wave-particle duality. The present book, however, contains papers based on a broad spectrum of basic ideas, some even opposite to those that Einstein and de Broglie would have liked. The order of the contributions in this book is alphabetical by first author's name. It is important here to stress the presence of three reviews of fundamental experimental data, by Hasselbach (electron interferometry), Rauch (neutron interferometry), and Tonomura (Aharonov-Bohm effect). Hasselbach reviews several interesting experiments performed in 1Ubingen with the electron biprism interferometer. Wave-particle duality is brought out in striking ways, e. g., in the buildup of an interference pattern out of single events. The Sagnac effect for electrons is also discussed. The chapter by Rauch presents interesting results on wave-particle duality for neutrons. Of particular interest are the differences between stochastic and deterministic absorption in the neutron interferometer, and the concrete evidence for the quantum-mechanical 41T-symmetry of spinors. In the short chapter by Tonomura, conclusive evidence for the reality of the Aharonov Bohm effect is reviewed, collected in experiments based on advanced technologies of electron holography and microlithography.

From September 24 through 30, 1992 the Workshop on "Waves and Parti cles in Light and Matter" was held in the Italian city of Trani in celebration of the centenary of Louis de Broglie's birth. As is well known, the relationship between quantum theory and ob jective reality was one of the main threads running through the researches of this French physicist. It was therefore in a fitting tribute to him on his 90th birthday that ten years ago an international conference on the same subject was convened in Perugia. On that occasion, physicists from all over the world interested in the problematics of wave-particle duality engaged in thoughtful debates (the proceedings of which were subsequently published) on recent theoretical and experimental developments in our understanding of the foundations of quantum mechanics. This time around, about 120 scientists, coming from 5 continents, in the warm and pleasant atmosphere of Trani's Colonna Conference Center focussed their discussions on recent results concerned with the EPR para dox, matter-interferometry, reality of de Broglie's waves, photon detection, macroscopic quantum coherence, alternative theories to usual quantum mechanics, special relativity, state reduction, and other related topics. The workshop was organized in plenary sessions, round tables, and poster sessions, and the present volume collects most-but not all-of the presented papers. A number of acknowledgements are due. We thank, first of all, the contributors, without whose constant dedication this volume could not have been published.

Are we alone? If so, Particle and Wave insists that we need not be lonely. Here the periodic table of elements—a system familiar to many of us from high school chemistry—unfolds in a series of unexpected meanings with connotations public, personal, and existential. Based on a logic that considers the atomic symbol an improvised phoneme, Particle and Wave is keenly attuned to the qualities of voice and concerned with how these improvisations fall on the listening ear. From the most recent housing bust, to the artistic visions of Christo and Jeanne Claude, to the labors of the Curies, to Pliny the Younger’s account of the eruption of Vesuvius, culture and world histories are recontextualized through the lens of personal experience. Muscular, precise, structurally varied, and imagistic, these poems engage in lyricism yet resist mere confession. In doing so they project the self as a composite, speaking in a variety of registers, from the nursery rhyme songster, to the ascetic devotee, to the unapologetic sensualist. They welcome all comers and elbow the bounded physical world to make way for a dynamic, new subjectivity.

This volume brings together eleven essays by the distinguished philosopher of science, Peter Achinstein. The unifying theme is the nature of the philosophical problems surrounding the postulation of unobservable entities such as light waves, molecules, and electrons. How, if at all, is it possible to confirm scientific hypotheses about "unobservables"? Achinstein examines this question as it arose in actual scientific practice in three nineteenth-century episodes: the debate between particle and wave theorists of light, Maxwell's kinetic theory of gases, and J.J. Thomson's discovery of the electron. The book contains three parts, each devoted to one of these topics, beginning with an essay presenting the historical background of the episode and an introduction to the philosophical issues. There is an illuminating evaluation of various scientific methodologies, including hypothetico-deductivism, inductivism, and the method of independent warrant which combines features of the first two. Achinstein assesses the philosophical validity of both nineteenth-century and modern answers to questions about unobservables, and presents and defends his own solutions.

Light and Vacuum presents a synthesis of selected fundamental topics of electromagnetic wave theory and quantum electrodynamics (QED) and analyzes the main theoretical difficulties encountered to ensure a coherent mathematical description of the simultaneous wave–particle nature of light, put in evidence by the experiments. The notion and the role of the quantum vacuum, strongly related to light, are extensively investigated. Classical electrodynamics issued from Maxwell's equations revealed the necessity of introducing the notion of volume for an electromagnetic wave to stand entailing precise values of cut-off wavelengths to account for the shape and dimensions of the surrounding space. Conversely, in QED, light is considered to be composed of point particles disregarding the conceptual question on how the frequency of oscillating electric and magnetic fields may be attributed to a point particle. To conciliate these concepts, the book provides a comprehensive overview of the author's work, including innovative contributions on the quantization of the vector potential amplitude at a single photon state, the non-local simultaneous wave–particle mathematical representation of the photon and finally the quantum vacuum. The purpose of the advanced elaborations is to raise questions, give hints and answers, and finally aspire for further theoretical and experimental studies in order to improve our knowledge and understanding on the real essence of Light and Vacuum. Contents:IntroductionHistorical Survey and Experimental EvidenceBasic Principles of the Electromagnetic Wave TheoryFrom Electromagnetic Waves to Quantum ElectrodynamicsTheory, Experiments and QuestionsAnalysis of the Electromagnetic Field Quantization Process and the Photon Vector Potential. The Non-Local Photon Wave-Particle Representation and the Quantum VacuumEpilogue Readership: This book is recommended for advanced postgraduate students and researchers who are interested in Quantum Mechanics and Electrodynamics. Key Features:The main mathematical ambiguities of the quantum electrodynamics formalism are clearly put in evidence, such as: derivation of the Hamiltonian without respecting Heisenberg's commutation relations, lack of an interaction Hamiltonian between the vacuum state and the electrons, singularities … etc.The basic aspect of Quantum Electrodynamics related to the quantization of the vector potential amplitude of the electromagnetic field to a single photon state α0k (ωk) = ξωk, which derives directly from Maxwell's equations, is uniquely described in this manuscriptA coherent mathematical coupling of the electromagnetic wave theory and quantum electrodynamics is fully provided resulting in a unique simultaneous wave particle formalism for the photon, in agreement with the experimental evidenceThe quantum vacuum issues arise naturally from the vector potential quantization procedure and corresponds to a very low energy density, compatible with recent astrophysical observations. Furthermore, it is explicitly expressed as a function of creation and annihilation operators permitting direct interactions with the electronsKeywords:Light;Electromagnetic Field;Second Quantization;Photons;Electrons;Quantum Vacuum

The Louis de Broglie Foundation (which was created in 1973, for the fiftieth anniversary of the discovery of wave mechanics) and the University of Perugia, have offered an international symposium to Louis de Broglie on his 90th birthday. This publication re presents the Proceedings of this conference which was held in Perugia on April 22-30, 1982. It was an opportunity for the developing of physical conceptions of all origins, which may serve to throw light on the mysterious power of the quantum theory. Quantum Mechanics has reached matu rity in its formalism and although no experiment yet has come to challenge its predictions, one may question the limits of its va lidity. In fact the true meaning of this vision of the microphysi cal world remains the subject of endless debating, at the heart of which lies "the foundational myth" of wave-particle dualism. Albert Einstein and Louis de Broglie are the two discoverers of this fundamental duality, which they always considered as a deep physical reality rather than a phenomenological artifice. During the conference a survey has been given of the essential recent experimental results in corpuscular and quantum optics and the most up-to-date theoretical aspects of the specificity of mi crophysical phenomena : various interpretations of quantum mecha nics, "al ternati ve theories" and hidden parameters theories, pro· babilistic and axiomatic questions and tentative crucial experi ments. The conference took place in the magnificent atmosphere of the villa Colombella lent to us by the Universita per Stranieri di Perugia.

Focusing on the unresolved debate between Newton and Huygens from 300 years ago, The Nature of Light: What is a Photon? discusses the reality behind enigmatic photons. It explores the fundamental issues pertaining to light that still exist today. Gathering contributions from globally recognized specialists in electrodynamics and quantum optics, the book begins by clearly presenting the mainstream view of the nature of light and photons. It then provides a new and challenging scientific epistemology that explains how to overcome the prevailing paradoxes and confusions arising from the accepted definition of a photon as a monochromatic Fourier mode of the vacuum. The book concludes with an array of experiments that demonstrate the innovative thinking needed to examine the wave-particle duality of photons. Looking at photons from both mainstream and out-of-box viewpoints, this volume is sure to inspire the next generation of quantum optics scientists and engineers to go beyond the Copenhagen interpretation and formulate new conceptual ideas about light–matter interactions and substantiate them through inventive applications.

This achingly beautiful novel considers how to measure love when it has the power to both save and destroy. Levon Grady and Samantha Vash are both students at an alternative high school for high-achieving but troubled teens. They have been chosen for a year-long project where they write their life stories and collect interviews from people who know them. The only rule is 100% confidentiality—they will share their work only with each other. What happens will transform their lives. Told from the perspectives of Levon, Sam, and all the people who know them best, this is a love story infused with science and the exploration of identity. In Love Is Both Wave and Particle, Paul Cody looks at how love behaves in different situations, and how it can shed light on even the darkest heart. Praise for Love is Both Wave and Particle: "[A] series of first-person narratives from the teens’ parents, classmates, and counselor . . . offer varied perspectives on Sam and quiet, handsome Levon Grady, who is “maybe somewhere on the broad spectrum of Asperger’s,” as he puts it. . . . Part romance, part psychological study, adult author Cody’s first book for teens thoughtfully conveys Sam and Levon’s complex mental states, the evolution of their relationship, and their journeys of self-discovery." —Publishers Weekly

The quantum and relativity theories of physics are considered to underpin all of science in an absolute sense. This monograph argues against this proposition primarily on the basis of the two theories' incompatibility and of some untenable philosophical implications of the quantum model. Elementary matter is assumed in both theories to occur as zero-dimensional point particles. In relativity theory this requires the space-like region of the underlying Minkowski space-time to be rejected as unphysical, despite its precise mathematical characterization. In quantum theory it leads to an incomprehensible interpretation of the wave nature of matter in terms of a probability function and the equally obscure concept of wave-particle duality. The most worrisome aspect about quantum mechanics as a theory of chemistry is its total inability, despite unsubstantiated claims to the contrary, to account for the fundamental concepts of electron spin, molecular structure, and the periodic table of the elements. A remedy of all these defects by reformulation of both theories as nonlinear wave models in four-dimensional space-time is described.

The early twentieth century brought about the rejection by physicists of the doctrine of determinism - the belief that complete knowledge of the initial conditions of an interaction in nature allows precise and unambiguous prediction of the outcome. This book traces the origins of a central problem leading to this change in viewpoint and paradoxes raised by attempts to formulate a consistent theory of the nature of light. It outlines the different approaches adopted by members of different national cultures to the apparent inconsistencies, explains why Einstein's early (1905) attempt at a resolution was not taken seriously for fifteen years, and describes the mixture of ideas that created a route to a new, antideterministic formulation of the laws of nature. Dr Wheaton describes the experimental work on the new forms of radiation found at the turn of the century and shows how the interpretation of energy transfer from X-rays to matter gradually transformed a classical wave explanation of light to one based on particle like quanta of energy, and further, he explains how influential scientists came reluctantly to accept a wavelike interpretation of matter as well. This new and distinctively different account of one of the major theoretical shifts in modern physical thought will be of fundamental interest to physical scientists and philosophers, as well as to historians of science.
