A Guide through the Mysteries of Quantum Physics! Yakir Aharonov is one of the pioneers in measuring theory, the nature of quantum correlations, superselection rules, and geometric phases and has been awarded numerous scientific honors. The author has contributed monumental concepts to theoretical physics, especially the Aharonov-Bohm effect and the Aharonov-Casher effect. Together with Daniel Rohrlich, Israel, he has written a pioneering work on the remaining mysteries of quantum mechanics. From the perspective of a preeminent researcher in the fundamental aspects of quantum mechanics, the text combines mathematical rigor with penetrating and concise language. More than 200 exercises introduce readers to the concepts and implications of quantum mechanics that have arisen from the experimental results of the recent two decades. With students as well as researchers in mind, the authors give an insight into that part of the field, which led Feynman to declare that "nobody understands quantum mechanics". * Free solutions manual available for lecturers at www.wiley-vch.de/supplements/
Modern physics is characterized by two great theories, which make it fundamentally different from its predecessor: quantum theory and theory of relativity. In this book we want to bring to the reader's attention several solutions to problems connected to the quantum-relativistic interaction of particles. Remarkably, such solutions furnished rigorous and pertinent explanations of a large set of phenomena, both in microscopic world and galactic universe.
Quantum physics started in the 1920's with wave mechanics and the wave-particle duality. However, the last 20 years have seen a second quantum revolution, centered around non-locality and quantum correlations between measurement outcomes. The associated key property, entanglement, is recognized today as the signature of quantumness. This second revolution opened the possibility of studying quantum correlations without any assumption on the internal functioning of the measurement apparata, the so-called Device-Independent Approach to Quantum Physics. This thesis explores this new approach using the powerful geometrical tool of polytopes. Emphasis is placed on the study of non-locality in the case of three or more parties, where it is shown that a whole new variety of phenomena appear compared to the bipartite case. Genuine multiparty entanglement is also studied for the first time within the device-independent framework. Finally, these tools are used to answer a long-standing open question: could quantum non-locality be explained by influences that propagate from one party to the others faster than light, but that remain hidden so that one cannot use them to communicate faster than light? This would provide a way around Einstein's notion of action at a distance that would be compatible with relativity. However, the answer is shown to be negative, as such influences could not remain hidden.
Housing is an investment. Investment prices must go up. Housing is shelter. When the price of shelter goes up, people experience distress. This is the housing trap. It’s time to escape. In Escaping the Housing Trap: The Strong Towns Response to the Housing Crisis, renowned urbanists Charles (Chuck) Marohn and Daniel Herriges introduce a first-of-its-kind discussion of the tension between housing as a financial product and housing as shelter. This is the key insight that’s been missing from the Housing Crisis Conversation; and the insight that can help cities fight back against the crisis from the bottom-up. This book offers a serious, yet accessible, history of housing policy in the United States and explains how it led us to this point in time: where we face a market that is rigged against people who, only a few decades ago, could have been homeowners or stable, long-term rentals. Only local change, on a neighborhood or city-wide scale, can begin to restore balance to the housing market. Escaping the Housing Trap is the must-read resource for everyone with a stake in the future of housing in America—and that means everyone. Readers will find: Discussions of housing as an investment and how the country's neighborhoods are being transformed by the introduction of large amounts of investment Explorations of housing as shelter, including discussions of zoning policy and NIMBYism A comprehensive overview of the Strong Towns approach to solving the American housing crisis
In this ambitious exploration of how foreign trade policy is made in democratic regimes, Daniel Verdier shows that special interests, party ideologues, and state officials and diplomats act as agents of the voters. Constructing a general theory in which existing theories (rent-seeking, median voting, state autonomy) function as partial explanations, he shows that trade institutions are not fixed entities but products of political competition.
Facebook, Twitter, Snapchat, YouTube, LinkedIn, and dozens of other services have been described as the vanguard of creative destruction across the media industries-disruptors of established business, heroes of a new economic narrative that supposes that the attention of individual users can be measured, managed, manipulated, backing methods that securitized, patented, and litigated attention in ways impossible before. Selling Social Media catalogues the key terms and discourses of the rise of social media firms with a particular emphasis on monetization, securitization, disruption, and litigation. Tensions between ideas and terms are critical, as the ways that different aspects of social media business are described change depending on the audience, scale, and maturity of the firm. These divergent discourses are bound together into a single story of social media, an industry that challenges the theories and descriptions of media that have come before. Through a reading of social media business this book offers a chance to revisit media theory in the context of a new social media companies and products that depend on a different understanding of media audiences, media industries, and public agency.
This book analyzes in considerable generality the quantization-dequantization integral transform scheme of Weyl and Wigner, and considers several phase operator theories. It features: a thorough treatment of quantization in polar coordinates; dequantization by a new method of “motes”; a discussion of Moyal algebras; modifications of the transform method to accommodate operator orderings; a rigorous discussion of the Dicke laser model for one mode, fully quantum, in the thermodynamic limit; analysis of quantum phase theories based on the Toeplitz operator, the coherent state operator, the quantized phase space angle, and a sequence of finite rank operators.
This book is devoted to the fundamentals of classical electrodynamics, one of the most beautiful and productive theories in physics. A general survey on the applicability of physical theories shows that only few theories can be compared to electrodynamics. Essentially, all electric and electronic devices used around the world are based on the theory of electromagnetism. It was Maxwell who created, for the first time, a unified description of the electric and magnetic phenomena in his electromagnetic field theory. Remarkably, Maxwell’s theory contained in itself also the relativistic invariance of the special relativity, a fact which was discovered only a few decades later. The present book is an outcome of the authors’ teaching experience over many years in different countries and for different students studying diverse fields of physics. The book is intended for students at the level of undergraduate and graduate studies in physics, astronomy, engineering, applied mathematics and for researchers working in related subjects. We hope that the reader will not only acquire knowledge, but will also grasp the beauty of theoretical physics. A set of about 130 solved and proposed problems shall help to attain this aim.
Provides an overview of the big issues in the business world today, with firsthand accounts from young leaders tasked with tackling these issues head on.
According respect to both prevailing models of divorce-as inevitably disastrous and as potentially challenging, even growth-producing-Dr. Twaite and his colleagues undertake a systematic and critical review of the literature on the differential psychosocial adjustment of children after a divorce. They address studies in ten predictor domains, some expectable (age, gender, custody arrangements), some less conventional, before advancing a predictor of their own: the effectiveness of parenting behavior (custodial, non-custodial, and step-) as experienced by the child. Finally, they proffer correctives, substantive and procedural, for future investigations, including recognition of the dynamics among the variables and the need to control for mediating factors in analyzing results. This is a monumental collection in the best tradition of social science research-thorough, responsible, accessible, and of course timely
This book is intended for undergraduate and graduate students in physics, engineering, astronomy, applied mathematics and for researchers working in related subjects. It is an excellent study tool for those students who would like to work independently on more electrodynamics problems in order to deepen their understanding and problem solving skills. The book discusses main concepts and techniques related to Maxwell's equations, potentials and fields (including Liénard-Wiechert potentials), electromagnetic waves, and the interaction and dynamics of charged point particles. It also includes content on magnetohydrodynamics and plasma, radiation and antennas, special relativity, relativistic kinematics, relativistic dynamics and relativistic-covariant dynamics and general theory of relativity. It contains a wide range of problems, ranging from electrostatics and magnetostatics to the study of the stability of dynamical systems, field theories and black hole orbiting. The book even contains interdisciplinary problems from the fields of electronics, elementary particle theory, antenna design. Detailed, step-by step calculations are presented, meeting the need for a thorough understanding of the reasoning and steps of the calculations by all students, regardless of their level of training. Additionally, numerical solutions are also proposed and accompanied by adjacent graphical representations and even multiple methods of solving the same problem. It is structured in a coherent and unified way, having a deep didactic character, being thus oriented towards a university environment, where the transmission of knowledge in a logical, unified and coherent way is essential. It teaches students how to think about and how to approach solving electrodynamics problems. - Contains a wide range of problems and applications from the fields of electrodynamics and the theory of special relativity. - Presents numerical solutions to problems involving nonlinearities. - Details command lines specific to Mathematica software dedicated to both analytical and numerical calculations, which allows readers to obtain the numerical solutions as well as the related graphical representations.
The surprising roles of instruments and experimentation in acquiring knowledge In Philosophical Instruments Daniel Rothbart argues that our tools are not just neutral intermediaries between humans and the natural world, but are devices that demand new ideas about reality. Just as a hunter's new spear can change their knowledge of the environment, so can the development of modern scientific equipment alter our view of the world. Working at the intersections of science, technology, and philosophy, Rothbart examines the revolution in knowledge brought on by recent advances in scientific instruments. Full of examples from historical and contemporary science, including electron scanning microscopes, sixteenth-century philosophical instruments, and diffraction devices used by biochemical researchers, Rothbart explores the ways in which instrumentation advances a philosophical stance about an instrument's power, an experimenter's skills, and a specimen's properties. Through a close reading of engineering of instruments, he introduces a philosophy from (rather than of) design, contending that philosophical ideas are channeled from design plans to models and from model into the use of the devices.
