This book explores the relationship between Dickens's novels and the financial system. Elements of Dickens's work form a critique of financial capitalism. This critique is rooted in the difference between use-value and exchange-value, and in the difference between productive circulations and mere accumulation. In a money-based society, exchange-value and accumulation dominate to the point where they infect even the most important and sacred relationships between parts of society and individuals. This study explores Dickens's critique from two very different points of view. The first is philosophical, from Aristotle's distinction between "chrematistic" accumulation and "economic" use on money through Marx's focus on the teleology of capitalism as death. The second view is that of nineteenth-century financial journalism, of "City" writers like David Morier Evans and M. L. Meason,, who, while functioning as "cheerleaders" for financial capitalism, also reflected some of the very real "dis-ease" associated with capital formation and accumulation. The core concepts of this critique are constant in the novels, but the critique broadens and becomes more pessimistic over time. The ill effects of living in a money-based society are presented more as the consequences of individual evil in earlier novels, while in the later books they are depicted as systemic and pervasive. Texts discussed include Nicholas Nickleby, A Christmas Carol, Little Dorrit and Our Mutual Friend.
Into the short compass of this book, Professor Graetz has succeeded in compressing an eminently readable survey of the directions in which the atomic theory, as accepted in the nineteenth century, has been extended by the remarkable and almost revolutionary physical investigations and discoveries of the two decades preceding the book's original publication in 1923.
Summarising the most novel facts and theories which were coming into prominence at the time, particularly those which had not yet been incorporated into standard textbooks, this important work was first published in 1921. The subjects treated cover a wide range of research that was being conducted into the atom, and include Quantum Theory, the Bohr Theory, the Sommerfield extension of Bohr's work, the Octet Theory and Isotopes, as well as Ionisation Potentials and Solar Phenomena. Because much of the material of Atomic Theories lies on the boundary between experimentally verified fact and speculative theory, it indicates in a unique way how the future of physics was perceived at the time of writing. It thus throws into stark relief not only the immense advances made since the 1920s, but also, perhaps, highlights the importance of not rigidly adhering to a particular program of future discoveries.
Now ubiquitous in public discussions about cutting-edge science and technology, nanoscience has generated many advances and inventions, from the development of new quantum mechanical methods to far-reaching applications in electronics and medical diagnostics. Ushering in the next technological era, Fundamentals of Picoscience focuses on the instrumentation and experiments emerging at the picometer scale. One picometer is the length of a trillionth of a meter. Compared to a human cell of typically ten microns, this is roughly ten million times smaller. In this state-of-the-art book, international scientists and researchers at the forefront of the field present the materials and methods used at the picoscale. They address the key challenges in developing new instrumentation and techniques to visualize and measure structures at this sub-nanometer level. With numerous figures, the book will help you: Understand how picoscience is an extension of nanoscience Determine which experimental technique to use in your research Connect basic studies to the development of next-generation picoelectronic devices The book covers various approaches for detecting, characterizing, and imaging at the picoscale. It then presents picoscale methods ranging from scanning tunneling microscopy (STM) to spectroscopic approaches at sub-nanometer spatial and energy resolutions. It also covers novel picoscale structures and picometer positioning systems. The book concludes with picoscale device applications, including single molecule electronics and optical computers. Introductions in each chapter explain basic concepts, define technical terms, and give context to the main material.
Although the current world order is still dominated by the US, there is increasing international concern over the possibility of regional security dilemmas arising from smaller powers' attempts to develop Weapons of Mass Destruction. A study of US-North Korean interaction using the security dilemma as a conceptual frame of analysis is thus not only hugely topical, but also particularly relevant for the 21st century on theoretical as well as empirical grounds. Is there the prospect of a security dilemma contagion if North Korea acquire nuclear weapons capability leading to an Asia Pacific wide nuclear arms race? This book examines this contentious issue in-depth and explores the difficult choices policymakers face as a result of the uncertainty in international politics.
This book is about several questions regarding how to describe the quantization of the current density in an antenna and about the nature of the quantum electromagnetic field produced by such a quantum current density. The second quantized current density can be built out of the Dirac field of electrons and positrons while the free electromagnetic or photon field is built out of solutions to the wave equation with coefficients being operators, namely the creation and annihilation operators of the photons.

All solids are composed of atoms or molecules and in order to explain their behavior, experiments and theories came forward. Simultaneously, many new materials were synthetically and systematically developed in the laboratories, properties of which needed to be understood before deploying them in various technologies. It is known that there is a strong correlation between structure and properties of materials. Therefore, experiments on solids involve understanding their structure with diffraction techniques using X-rays, electrons or neutrons. The materials may be in different forms like bulk solid, thin films or powders and need to be observed using microscopes. Finally the properties can be correlated to electronic structure which can be deciphered through various spectroscopy techniques. Magnetic measurements give the insight in to electron-electron correlation. The advantages and limitations of the techniques are also spelled out. In other words, this book takes into account the unaddressed needs of students and teachers associated with the experimental methods. Its relevance has increased manifold, as it addresses a wide scope of the topics in concise manner. Such as' improving signal-to-noise ratio, cryogenic methods, vacuum science, sources and detectors for electrons, photons (from infra-red to gamma rays), error analysis, statistical handling of data, etc. Please note: This title is co-published with Capital Publishers, New Delhi.

Interaction of Radiation with Matter focuses on the physics of the interactions of ionizing radiation in living matter and the Monte Carlo simulation of radiation tracks. Clearly progressing from an elementary level to the state of the art, the text explores the classical physics of track description as well as modern aspects based on condensed matter physics. The first section of the book discusses the fundamentals of the radiation field. In the second section, the authors describe the cross sections for electrons and heavy ions-the most important information needed for simulating radiation track at the molecular level. The third section details the inelastic scattering and energy loss of charged particles in condensed media, particularly liquid water. The final section contains a large number of questions and problems to reinforce learning. Designed for radiation interaction courses, this textbook is the ideal platform for teaching students in medical/health physics and nuclear engineering. It gives students a solid grounding in the physical understanding of radiation track structure in living matter, enabling them to pursue further work in radiological physics and radiation dosimetry.
This book provides a thorough introduction to the phenomenology of heavy flavour physics, those working on the B-factories, LHCb, BTeV, HERA and the Tevatron. It explains how heavy quark theory could be implemented on the lattice, and discusses the status of CP-violation in the neutral kaon system.
Building on Mozumder's and Hatano's Charged Particle and Photon Interactions with Matter: Chemical, Physicochemical, and Biological Consequences with Applications (CRC Press, 2004), Charged Particle and Photon Interactions with Matter: Recent Advances, Applications, and Interfaces expands upon the scientific contents of the previous volume by covering state-of-the-art advances, novel applications, and future perspectives. It focuses on relatively direct applications used mainly in radiation research fields as well as the interface between radiation research and other fields. The book first explores the latest studies on primary processes (the physical stage), particularly on the energy deposition spectra and oscillator strength distributions of molecules interacting with charged particles and photons. Other studies discussed include the use of synchrotron radiation in W-value studies and the progress achieved with positrons and muons interacting with matter. It then introduces new theoretical studies on the physicochemical and chemical stages that describe the behavior of electrons in liquid hydrocarbons and the high-LET radiolysis of liquid water. The book also presents new experimental research on the physicochemical and chemical stages with specific characteristics of matter or specific experimental conditions, before covering new experimental studies on the biological stage. The last set of chapters focuses on applications in health physics and cancer therapy, applications to polymers, the applications and interface formation in space science and technology, and applications for the research and development of radiation detectors, environmental conservation, plant breeding, and nuclear engineering. Edited by preeminent scientists and with contributions from an esteemed group of international experts, this volume advances the field by offering greater insight into how charged particles and photons interact with matter. Bringing together topics across a spectrum of scientific and technological areas, it provides clear explanations of the dynamic processes involved in and applications of interface formation.

The second part provides an introduction to the four key applications of atomic physics: lasers, cold atoms, solid-state spectroscopy and astrophysics. This highly pedagogical text includes worked examples and end of chapter problems to allow students to test their knowledge, as well as numerous diagrams of key concepts, making it perfect for undergraduate students looking for a succinct primer on the concepts and applications of atomic physics.
From superstring theory to models with extra dimensions to dark matter and dark energy, a range of theoretically stimulating ideas have evolved for physics beyond the standard model. These developments have spawned a new area of physics that centers on the interplay between particle physics and cosmology-astroparticle physics. Providing the necessary theoretical background, Particle and Astroparticle Physics clearly presents the many recent advances that have occurred in these fields. Divided into five parts, the book begins with discussions on group and field theories. The second part summarizes the standard model of particle physics and includes some extensions to the model, such as neutrino masses and CP violation. The next section focuses on grand unified theories and supersymmetry. The book then discusses the general theory of relativity, higher dimensional theories of gravity, and superstring theory. It also introduces various novel ideas and models with extra dimensions and low-scale gravity. The last part of the book deals with astroparticle physics. After an introduction to cosmology, it covers several specialized topics, including baryogenesis, dark matter, dark energy, and brane cosmology. With numerous equations and detailed references, this lucid book explores the new physics beyond the standard model, showing that particle and astroparticle physics will together reveal unique insights in the next era of physics.
Supersymmetry (SUSY) is one of the most important ideas ever conceived in particle physics. It is a symmetry that relates known elementary particles of a certain spin to as yet undiscovered particles that differ by half a unit of that spin (known as Superparticles). Supersymmetric models now stand as the most promising candidates for a unified theory beyond the Standard Model (SM). SUSY is an elegant and simple theory, but its existence lacks direct proof. Instead of dismissing supersymmetry altogether, Supersymmetry Beyond Minimality: from Theory to Experiment suggests that SUSY may exist in more complex and subtle manifestation than the minimal model. The book explores in detail non-minimal SUSY models, in a bottom-up approach that interconnects experimental phenomena in the fermionic and bosonic sectors. The book considers with equal emphasis the Higgs and Superparticle sectors, and explains both collider and non-collider experiments. Uniquely, the book explores charge/parity and lepton flavour violation. Supersymmetry Beyond Minimality: from Theory to Experiment provides an introduction to well-motivated examples of such non-minimal SUSY models, including the ingredients for generating neutrino masses and/or relaxing the tension with the heavily constraining Large Hadron Collider (LHC) data. Examples of these scenarios are explored in depth, in particular the discussions on Next-to-Minimal Supersymmetric SM (NMSSM) and B-L Supersymmetric SM (BLSSM).
This book explores the relationship of several of Dickens's texts
(Nicholas Nickleby, A Christmas Carol, Little Dorrit and Our Mutual
Friend) with the system of finance capitalism, both as reflections
of the evolution of that system, and as attempts to shape and
influence, if not the system itself, at least public opinion about
the system and the actions of those who participated in it.
Specifically, the book examines elements of Dickens's work that
form a critique of financial capitalism. Dickens's critique is
rooted in the difference between use-value and exchange-value, and
in the difference between productive circulations and mere
accumulation. The critique details how, in a money-based society,
exchange-value and accumulation become dominant to the point where
they infect even the most important social relations.
Much of our understanding of physics in the last 30-plus years has come from research on atoms, photons, and their interactions. Collecting information previously scattered throughout the literature, Modern Atomic Physics provides students with one unified guide to contemporary developments in the field.

The search for the elementary constituents of the physical universe and the interactions between them has transformed over time and continues to evolve today, as we seek answers to questions about the existence of stars, galaxies, and humankind. Integrating both theoretical and experimental work, Exploring Fundamental Particles traces the development of this fascinating field, from the discoveries of Newton, Fermi, and Feynman to the detection of CP violation and neutrinos to the quest to observe the Higgs boson and beyond. An Accessible yet In-Depth Account of How Fundamental Particles Shape Our World The book first examines the experiments and theoretical ideas that gave rise to the standard model. It discusses special relativity, angular momentum, spin, the Dirac electron, quantum field theory, Feynman diagrams, Pauli's neutrino, Fermi's weak interaction, Yukawa's pion, the muon neutrino, quarks, leptons, and flavor symmetry. The authors then explain the violation of the symmetry between matter and antimatter, known as CP violation. They cover the discoveries of CP violation in the decays of kaons and B mesons as well as future experiments that could detect possible CP violation beyond the standard model. In the next part, the authors present experimental results involving the once-mysterious neutrino. They explore the evidence that neutrinos have mass, new neutrino experiments in various countries, and the potential of neutrino astronomy to offer a new perspective on stars and galaxies. The final section focuses on the one undetected particle of the standard model: the Higgs boson. The authors review the experiments that established important constraints on the mass of the Higgs particle. They also highlight recent experiments of the Tevatron particle accelerator at Fermilab, along with the near future impact of the Large Hadron Collider (LHC) at CERN and th

Recent research has brought the application of microwaves from the classical fields of heating, communication, and generation of plasma discharges into the generation of compact plasmas that can be used for applications such as FIB and small plasma thrusters. However, these new applications bring with them a new set of challenges. With coverage ranging from the basics to new and emerging applications, Compact Plasma and Focused Ion Beams discusses how compact high-density microwave plasmas with dimensions smaller than the geometrical cutoff dimension can be generated and utilized for providing focused ion beams of various elements. Starting with the fundamentals of the cutoff problem for wave propagation in waveguides and plasma diagnostics, the author goes on to explain in detail the plasma production by microwaves in a compact geometry and narrow tubes. He then thoroughly discusses wave interaction with bounded plasmas and provides a deeper understanding of the physics. The book concludes with an up-to-date account of recent research on pulsed microwaves and the application of compact microwave plasmas for multi-element FIB. It provides a consolidated and unified description of the emerging areas in plasma science and technology utilizing wave-based plasma sources based on the author's own work and experience. The book will be useful not only to established researchers in this area but will also serve as an excellent introduction to those interested in applying these ideas to various current and new applications. |
