Physics of Societal Issues

by David Hafemeister

This book provides the reader with essential tools needed to analyze complex societal issues and demonstrates the transition from physics to modern-day laws and treaties. This second edition features new equation-oriented material and extensive data sets drawing upon current information from experts in their fields. Problems to challenge the reader and extend discussion are presented on three timely issues: * National Security: Weapons, Offense, Defense, Verification, Nuclear Proliferation, Terrorism * Environment: Air/Water, Nuclear, Climate Change, EM Fields/Epidemiology * Energy: Current Energy Situation, Buildings, Solar Buildings, Renewable Energy, Enhanced End-Use Efficiency, Transportation, Economics Praise for the first edition: "This insight is needed in Congress and the Executive Branch. Hafemeister, a former Congressional fellow with wide Washington experience, has written a book for physicists, chemists and engineers who want to learn science and policy on weapons, energy, and the environment. Scientists who want to make a difference will want this book. " Richard Scribner, first Director, Congressional Science and Engineering Fellow Program, AAAS "Hafemeister shows how much one can understand about nuclear weapons and missile issues through simple back-of-the-envelope calculations. He also provides compact explanations of the partially successful attempts that have been made over the past 60 years to control these weapons of mass destruction. Hopefully, Physics of Societal Issues will help interest a new generation of physicists in continuing this work. " Frank von Hippel, Professor, Princeton, former Assistant Director, National Security, White House, OSTP "Energy policy must be quantitative. People who don't calculate economic tradeoffs often champion simplistic hardware. 'The solution is more. . . nuclear power, or electric cars, or photovoltaics, etc. ' Some simple physics will show that the true solution matches supply and demand as an 'integrated resource plan. ' Physics of Societal Issues is a good place to begin this journey. " Arthur Rosenfeld, former California Energy Commissioner, Professor-emeritus, U. of California-Berkeley

Physics of Soft Impact and Cratering

by Hiroaki Katsuragi

This book focuses on the impact dynamics and cratering of soft matter to describe its importance, difficulty, and wide applicability to planetary-related problems. A comprehensive introduction to the dimensional analysis and constitutive laws that are necessary to discuss impact mechanics and cratering is first provided. Then, particular coverage is given to the impact of granular matter, which is one of the most crucial constituents for geophysics. While granular matter shows both solid-like and fluid-like behaviors, neither solid nor fluid dynamics is sufficient to fully understand the physics of granular matter. In order to reveal its fundamental properties, extensive impact tests have been carried out recently. The author reveals the findings of these recent studies as well as what remains unsolved in terms of impact dynamics. Impact crater morphology with various soft matter impacts also is discussed intensively. Various experimental and observational results up to the recent Itokawa asteroid's terrain and nanocrater are reviewed and explained mainly by dimensional analysis. The author discusses perspectives of the relation between soft matter physics and planetary science, because it is an important step towards unifying physics and planetary science, in both of which fields crater morphology has been studied independently.

Physics of Thin-Film Photovoltaics

by Victor G. Karpov Diana Shvydka

It appears rather paradoxical that thin-film photovoltaics (PVs) are made of materials that seem unacceptable from the classical PV perspective, and yet they often outperform classical PV. This exciting new volume solves that paradox by switching to a new physics paradigm. Many concepts here fall beyond the classical PV scope. The differences lie in device thinness (microns instead of millimeters) and morphology (non-crystalline instead of crystalline). In such structures, the charge carriers can reach electrodes without recombination. On the other hand, thin disordered structures render a possibility of detrimental lateral nonuniformities (“recombination highways”), and their energy spectra give rise to new recombination modes. The mechanisms of thermal exchange and device degradation are correspondingly unique. The overall objective of this book is to give a self-contained in-depth discussion of the physics of thin-film systems in a manner accessible to both researchers and students. It covers most aspects of the physics of thin-film PV, including device operations, material structure and parameters, thin-film junction formation, analytical and numerical modeling, concepts of large area effects and lateral non-uniformities, physics of shunting (both shunt growth and effects), and device degradation. Also, it reviews a variety of physical diagnostic techniques proven with thin-film PV. Whether for the veteran engineer or the student, this is a must-have for any library.

Physics of Ultra-Cold Matter

by Hugo Terças J. T. Mendonça

The advent of laser cooling of atoms led to the discovery of ultra-cold matter, with temperatures below liquid Helium, which displays a variety of new physical phenomena. Physics of Ultra-Cold Matter gives an overview of this recent area of science, with a discussion of its main results and a description of its theoretical concepts and methods. Ultra-cold matter can be considered in three distinct phases: ultra-cold gas, Bose Einstein condensate, and Rydberg plasmas. This book gives an integrated view of this new area of science at the frontier between atomic physics, condensed matter, and plasma physics. It describes these three distinct phases while exploring the differences, as well as the sometimes unexpected similarities, of their respective theoretical methods. This book is an informative guide for researchers, and the benefits are a result from an integrated view of a very broad area of research, which is limited in previous books about this subject. The main unifying tool explored in this book is the wave kinetic theory based on Wigner functions. Other theoretical approaches, eventually more familiar to the reader, are also given for extension and comparison. The book considers laser cooling techniques, atom-atom interactions, and focuses on the elementary excitations and collective oscillations in atomic clouds, Bose-Einstein condensates, and Rydberg plasmas. Linear and nonlinear processes are considered, including Landau damping, soliton excitation and vortices. Atomic interferometers and quantum coherence are also included.

Physics of Waves

by Mark A. Heald William C. Elmore

Because of the increasing demands and complexity of undergraduate physics courses (atomic, quantum, solid state, nuclear, etc.), it is often impossible to devote separate courses to the classic wave phenomena of optics, acoustics, and electromagnetic radiation. This brief comprehensive text helps alleviate the problem with a unique overview of classical wave theory in one volume.By examining a sequence of concrete and specific examples (emphasizing the physics of wave motion), the authors unify the study of waves, developing abstract and general features common to all wave motion. The fundamental ideas of wave motion are set forth in the first chapter, using the stretched string as a particular model. In Chapter Two, the two-dimensional membrane is used to introduce Bessel functions and the characteristic features of waveguides. In Chapters Three and Four, elementary elasticity theory is developed and applied to find the various classes of waves that can be supported by a rigid rod. The impedance concept is also introduced at this point. Chapter Five discusses acoustic waves in fluids.The remainder of the book offers concise coverage of hydrodynamic waves at a liquid surface, general waves in isotropic elastic solids, electromagnetic waves, the phenomenon of wave diffraction, and other important topics. A special feature of this book is the inclusion of additional material designed to encourage the serious student to investigate topics often not covered in lectures. Throughout, the mathematics is kept relatively simple (mostly differential equations) and is accessible to advanced undergraduates with a year of calculus. In addition, carefully selected problems at the end of each section extend the coverage of the text by asking the student to supply mathematical details for calculations outlined in the section, or to develop the theory for related cases.Impressively broad in scope, Physics of Waves offers a novel approach to the study of classical wave theory -- a wide-ranging but thorough survey of an important discipline that pervades much of contemporary physics. The simplicity, breadth, and brevity of the book make it ideal as a classroom text or as a vehicle for self-study.

Physics of the Human Mind

by Ihor Lubashevsky

This book tackles the challenging question which mathematical formalisms and possibly new physical notions should be developed for quantitatively describing human cognition and behavior, in addition to the ones already developed in the physical and cognitive sciences. Indeed, physics is widely used in modeling social systems, where, in particular, new branches of science such as sociophysics and econophysics have arisen. However, many if not most characteristic features of humans like willingness, emotions, memory, future prediction, and moral norms, to name but a few, are not yet properly reflected in the paradigms of physical thought and theory. The choice of a relevant formalism for modeling mental phenomena requires the comprehension of the general philosophical questions related to the mind-body problem. Plausible answers to these questions are investigated and reviewed, notions and concepts to be used or to be taken into account are developed and some challenging questions are posed as open problems. This text addresses theoretical physicists and neuroscientists modeling any systems and processes where human factors play a crucial role, philosophers interested in applying philosophical concepts to the construction of mathematical models, and the mathematically oriented psychologists and sociologists, whose research is fundamentally related to modeling mental processes.

Physics of the Human Temporality: Complex Present (Understanding Complex Systems)

by Ihor Lubashevsky Natalie Plavinska

This book presents a novel account of the human temporal dimension called the “human temporality” and develops a special mathematical formalism for describing such an object as the human mind. One of the characteristic features of the human mind is its temporal extent. For objects of physical reality, only the present exists, which may be conceived as a point-like moment in time. In the human temporality, the past retained in the memory, the imaginary future, and the present coexist and are closely intertwined and impact one another.This book focuses on one of the fragments of the human temporality called the complex present. A detailed analysis of the classical and modern concepts has enabled the authors to put forward the idea of the multi-component structure of the present. For the concept of the complex present, the authors proposed a novel account that involves a qualitative description and a special mathematical formalism. This formalism takes into account human goal-oriented behavior and uncertainty in human perception.The present book can be interesting for theoreticians, physicists dealing with modeling systems where the human factor plays a crucial role, philosophers who are interested in applying philosophical concepts to constructing mathematical models, and psychologists whose research is related to modeling mental processes.

Physics of the Invisible Sun: Instrumentation, Observations, and Inferences

by Ashok Ambastha

Physics of the invisible Sun: Instrumentation, Observations, and Inferences provides a new updated perspectives of the dramatic developments in solar physics mainly after the advent of the space era. It focusses on the instrumentation exploiting the invisible windows of the electromagnetic spectrum for observing the outer, fainter layers of the Sun. It emphasizes on the several technical and observational challenges and proceeds to discuss the discoveries related to energetic phenomena occurring in the transition region and corona. The book begins with giving a brief glimpse of the historical developments during the pre-, and post-telescopic periods of visible and spectroscopic techniques, ground-based optical and radio observing sites. Various types of telescopes and back-end instrumentation are presented based on photometry, spectroscopy, and polarimetry using the Zeeman and Hanle effects for measurement of magnetic fields, and Doppler effect for radial velocity measurements. The book discusses theoretical and observational inferences based on detection of solar neutrinos, and helioseismology as the probes of the hidden solar interior, and tests of solar standard models. The characteristic properties and observational signatures of global solar p- and g-oscillations modes, developments in local helioseismology and asteroseismology are discussed. The role of the solar magnetic field and differential rotation in the activity and magnetic cycles, prediction methodologies, and dynamo models are described. Observing the Sun in IR at the longer, and the UV, EUV, XUV, X-rays, and gamma-rays at the shorter wavelengths are covered in detail. Observational challenges at each of these wavelengths are presented followed by the instrumentation for detection and imaging that have resulted in enhancing the understanding of various solar transient phenomena, such as, flares and CMEs. The outer most corona is described as a dynamic, expanding component of the Sun from the theoretical and observational perspectives of the solar wind. It then discusses the topics of the Interplanetary magnetic field, slow and fast solar wind, interaction with magnetised and non-magnetised objects of the solar system, the space weather and the physics of the heliosphere. The chapter on the future directions in solar physics presents a brief overview of the new major facilities in various observing windows, and the future possibilities of observing the Sun from ground and vantage locations in space. Features: Systematic overview of the developments in instrumentation, observational challenges and inferences derived from ground-based and space-borne solar projects. Advances in the understanding about the solar interior from neutrinos and helioseismology. Recent research results and future directions from ground- and space-based observations. This book may serve as a reference book for scientific researchers interested in multi-wavelength instrumentation and observational aspects of solar physics. It may also be used as a textbook for a graduate-level course.
