An Introduction to Tensors and Group Theory for Physicists
by Nadir JeevanjeeAn Introduction to Tensors and Group Theory for Physicists provides both an intuitive and rigorous approach to tensors and groups and their role in theoretical physics and applied mathematics. A particular aim is to demystify tensors and provide a unified framework for understanding them in the context of classical and quantum physics. Connecting the component formalism prevalent in physics calculations with the abstract but more conceptual formulation found in many mathematical texts, the work will be a welcome addition to the literature on tensors and group theory. Advanced undergraduate and graduate students in physics and applied mathematics will find clarity and insight into the subject in this textbook.
An Introduction to Thermodynamics and Statistical Physics (UNITEXT for Physics)
by Piero OllaThis textbook offers an advanced undergraduate or initial graduate level introduction to topics such as kinetic theory, equilibrium statistical mechanics and the theory of fluctuations from a modern perspective. The aim is to provide the reader with the necessary tools of probability theory and thermodynamics (especially the thermodynamic potentials) to enable subsequent study at advanced graduate level. At the same time, the book offers a bird's eye view on arguments that are often disregarded in the main curriculum courses. Further features include a focus on the interdisciplinary nature of the subject and in-depth discussion of alternative interpretations of the concept of entropy. While some familiarity with basic concepts of thermodynamics and probability theory is assumed, this does not extend beyond what is commonly obtained in basic undergraduate curriculum courses.

An Introduction to the Confinement Problem (Lecture Notes in Physics #821)
by Jeff GreensiteThis book addresses the confinement problem, which quite generally deals with the behavior of non-abelian gauge theories, and the force which is mediated by gauge fields, at large distances. The word "confinement" in the context of hadronic physics originally referred to the fact that quarks and gluons appear to be trapped inside mesons and baryons, from which they cannot escape. There are other, and possibly deeper meanings that can be attached to the term, and these will be explored in this book. Although the confinement problem is far from solved, much is now known about the general features of the confining force, and there are a number of very well motivated theories of confinement which are under active investigation. This volume gives a both pedagogical and concise introduction and overview of the main ideas in this field, their attractive features, and, as appropriate, their shortcomings.

This volume gives a both pedagogical and concise introduction and overview of the main ideas in this field, their attractive features, and, as appropriate, their shortcomings. This second edition summarizes some of the developments in this area which have occurred since the first edition of this book appeared in 2011. These include new results in the caloron/dyon picture of confinement, in functional approaches, and in studies of the Yang-Mills vacuum wave functional. Special attention, in two new chapters, is given to recent numerical investigations of the center vortex theory, and to the varieties of confinement which may exist in gauge-Higgs theories. Reviews of the first edition: “This is indeed a very good book. I enjoyed reading it and… I learned a lot from it.… It is definitely a research book that provides readers with a guide to the most updated confinement models.” (Giuseppe Nardelli, Mathematical Reviews, Issue 2012 d) “The book is beautifully produced with special emphasis on the relevance of center symmetry and lattice formulation as well as an introduction to current research on confinement.” (Paninjukunnath Achuthan, Zentralblatt MATH, Vol. 1217, 2011)
An Introduction to the Geography of Health
by Peter Anthamatten Helen HazenHealth issues such as the emergence of infectious diseases, the potential influence of global warming on human health, and the escalating strain of increasing longevity and chronic conditions on healthcare systems are of growing importance in an increasingly peopled and interconnected world. A geographic approach to the study of health offers a critical perspective to these issues, considering how changing relationships between people and their environments influence human health. An Introduction to the Geography of Health provides an accessible introduction to this rapidly growing field, covering theoretical and methodological background. The text is divided into three sections which consider distinct approaches and techniques related to health geographies. Section one introduces ecological approaches, with a focus on how natural and built environments affect human health. For instance, how have irrigation projects influenced the spread of water-borne diseases? How can modern healthcare settings, such as hospitals, affect the spread and evolution of pathogens? Section two discusses social aspects of health and healthcare, considering health as not merely a biological interaction between a pathogen and human host, but as a process that is situated among social factors which ultimately drive who suffers from what, and where disease occurs. Section three then considers spatial techniques and approaches to exploring health, giving special focus to the growing role of cartography and geographic information systems (GIS) in the study of health. This clearly written text contains a range of pedagogical features including a wealth of global case studies, discussion questions and suggestions for further reading at the end of each chapter, a colour plate section and over eighty diagrams and figures. The accompanying website also provides presentations, exercises, further resources, and tables and figures. This book is an essential introductory text for undergraduate students studying Geography, Health and Social Studies.
An Introduction to the Geography of Health
by Peter Anthamatten Helen HazenIn the second edition of An Introduction to the Geography of Health, Hazen and Anthamatten explore the ways in which geographic ideas and approaches can inform our understanding of health. The book’s focus on a broad range of physical and social factors that drive health in places and spaces offers students and scholars an important holistic perspective on the study of health in the modern era. In this edition, the authors have restructured the book to emphasize the theoretical significance of ecological and social approaches to health. Spatial methods are now reinforced throughout the book and other qualitative and quantitative methods are discussed in greater depth. Data and examples are used extensively to illustrate key points and have been updated throughout, including several new extended case studies such as water contamination in Flint Michigan, microplastics pollution, West Africa’s Ebola crisis, and the Zika epidemic. The book contains over one hundred figures, including new and updated maps, data graphics, and photos. The book is designed to be used as the core text for a health geography course for undergraduate and lower-level graduate students, and is relevant to students of biology, medicine, entomology, social science, urban planning, and public health.
An Introduction to the Geopolitics of Conflict, Nationalism, and Reconciliation in Ireland (Routledge Geopolitics Series)
by Kara E. DempseyThis book examines ethnoterritorial conflict and reconciliation in Ireland from the 1916 Rising to Brexit (2021), including the production and consequences of the island’s two distinct political units. Highlighting key geographic themes of bordering, unity, division, and national narratives, it explores how geopolitical space has been employed over time to (re)define divided national allegiances throughout Ireland and within Irish–British relations. The analysis draws from in-depth interviews and archival research, and spans supranational, state, municipal, neighborhood, and individual scales. The book pays particular attention to uneven power structures, statecraft, perceived truths, lived experiences, reconciliation efforts, and renegotiations of national narratives in the production of symbolic landscapes, divided cities, and "shared" space. An Introduction to the Geopolitics of Conflict, Nationalism, and Reconciliation in Ireland provides readers with an analysis of geopolitical power relations and different spatial productions of conflict and peacebuilding in Ireland. Offering deeper understanding of these historic and contemporary geopolitical intersections, this book makes a valuable contribution to the fields of Political Geography, Border Studies, Irish Studies, European Studies, International Relations, Cultural Geography, and Regional Studies.
An Introduction to the Global Circulation of the Atmosphere
by David RandallThis is a graduate-level textbook on the global circulation of the Earth's atmosphere--the large-scale system of winds by which energy is transported around the planet, from the tropical latitudes to the poles. Written by David Randall, one of the world's foremost experts on the subject, it is the most comprehensive textbook on the topic. Intended for Earth science students who have completed some graduate-level coursework in atmospheric dynamics, the book will help students build on that foundation, preparing them for research in the field.The book describes the many phenomena of the circulation and explains them in terms of current ideas from fluid dynamics and thermodynamics, with frequent use of isentropic coordinates and using the methods of vector calculus. It emphasizes the key roles of water vapor and clouds, includes detailed coverage of energy flows and transformations, and pays close attention to scale interactions. The book also describes the major historical contributions of key scientists, giving a human dimension to the narrative, and it closes with a discussion of how the global circulation is evolving as the Earth's climate changes.The most comprehensive graduate-level textbook on the subjectWritten by one of the world's leading expertsConnects global circulation and climate phenomenaAddresses energy, moisture, and angular-momentum balance; the hydrologic cycle; and atmospheric turbulence and convectionEmphasizes the energy cycle of the atmosphere; the role of moist processes; and circulation as an unpredictable, chaotic processHelps prepare students for researchAn online illustration package is available to professors
An Introduction to the Green Economy: Science, Systems and Sustainability
by Adrian C. Newton Elena CantarelloThe green economy is widely seen as a potential solution to current global economic and environmental crises, and a potential mechanism by which sustainable development might be achieved in practice. Considerable investments are now being made into the development of green technology, renewable energy, biodiversity conservation, resource efficiency, recycling of materials and green infrastructure. This textbook provides a comprehensive introduction to the green economy, using a strongly interdisciplinary approach based on environmental science, rather than treating it as a sub-set of economics. The scientific principles of sustainability are presented, which provide the foundations of the green economy, with a particular focus on systems-based approaches. Examples of real-world case studies are used to illustrate how the green economy can be achieved in practice. In this way, the authors provide a thorough overview of both the principles and practice of the green economy, drawing from a wide range of disciplines including ecology, geography, social science, psychology, sustainability science, environmental science, law and economics. The emphasis is on presenting results of the latest research, derived from leading scientific journals. Rather than focusing on a single definition of what constitutes a ‘green economy’, the book introduces readers to the diversity of opinion that exists, and engages them in what is an active, on-going debate. This reflects the fact that many aspects of the green economy, and sustainable development more generally, are currently contested. In particular, the book will help readers to strengthen their ability to critically evaluate the evidence for and against the views presented, and to actively contribute to the future development of the green economy.
An Introduction to the Meteorology and Climate of the Tropics
by J. F. GalvinWhat do we mean by the tropics? The weather and the climates it produces across the tropical zone are significantly different from those experienced by the people living in higher latitudes, so forecasters across Europe and much of North America are unfamiliar with its effects. In this book, Jim Galvin demystifies the topic in this zone that is increasingly of interest to those studying weather and climate. This book was written for weather forecasters, meteorology, environmental science and geography students as an introductory guide. It builds on the experience of the author, his professional experience in the World Area Forecast Centre at the Met Office, Exeter, using studies into the weather and climate seen within the tropical air mass conducted over many years. Its unique approach presents a practical approach to tropical weather studies, drawing on both academic and practical knowledge, covering air mass dynamics, seasonal changes, moist and dry weather, climate variability and human health in chapters and appendices that build up the overall picture, summarising our current state of knowledge. As an overview, it covers the broad range of effects connected with climate and weather in a straightforward way and is clearly illustrated throughout.
An Introductory Guide to Computational Methods for the Solution of Physics Problems (Lecture Notes in Physics #955)
by George Rawitscher Victo dos Santos Filho Thiago Carvalho PeixotoThis monograph presents fundamental aspects of modern spectral and other computational methods, which are not generally taught in traditional courses. It emphasizes concepts as errors, convergence, stability, order and efficiency applied to the solution of physical problems. The spectral methods consist in expanding the function to be calculated into a set of appropriate basis functions (generally orthogonal polynomials) and the respective expansion coefficients are obtained via collocation equations. The main advantage of these methods is that they simultaneously take into account all available information, rather only the information available at a limited number of mesh points. They require more complicated matrix equations than those obtained in finite difference methods. However, the elegance, speed, and accuracy of the spectral methods more than compensates for any such drawbacks. During the course of the monograph, the authors examine the usually rapid convergence of the spectral expansions and the improved accuracy that results when nonequispaced support points are used, in contrast to the equispaced points used in finite difference methods. In particular, they demonstrate the enhanced accuracy obtained in the solution of integral equations.The monograph includes an informative introduction to old and new computational methods with numerous practical examples, while at the same time pointing out the errors that each of the available algorithms introduces into the specific solution. It is a valuable resource for undergraduate students as an introduction to the field and for graduate students wishing to compare the available computational methods. In addition, the work develops the criteria required for students to select the most suitable method to solve the particular scientific problem that they are confronting.
An Introductory Path to Quantum Theory: Using Mathematics to Understand the Ideas of Physics
by Stephen Bruce SontzSince the 17th century, physical theories have been expressed in the language of mathematical equations. This introduction to quantum theory uses that language to enable the reader to comprehend the notoriously non-intuitive ideas of quantum physics. The mathematical knowledge needed for using this book comes from standard undergraduate mathematics courses and is described in detail in the section Prerequisites. This text is especially aimed at advanced undergraduate and graduate students of mathematics, computer science, engineering and chemistry among other disciplines, provided they have the math background even though lacking preparation in physics. In fact, no previous formal study of physics is assumed.
An Investment Perspective on Global Value Chains
by Yan Liu Christine Zhenwei Qiang Victor SteenbergenThis report investigates the role of foreign direct investment (FDI) in helping developing countries participate in global value chains (GVCs). It combines the perspectives and strategies from three types of players: multinational corporations, domestic firms and governments. It aims to provide practical guidance for developing countries to develop strategies that use FDI to strengthen GVC participation and upgrading. The report has six main chapters: 1. FDI and GVCs. Assesses the trade-investment nexus and analyzes the effect of FDI in countries’ GVC participation and upgrading at the country level. 2. MNCs shape GVC development. Highlights MNCs' contribution to global economy and how their business strategies shape the evolution of GVCs. The chapter also compares MNCs' business strategies in terms of outsourcing and offshoring, risk mitigation and increasing market power across GVC archetypes. 3. Domestic firm perspectives on GVC participation. Looks at the various paths domestic firms can take to internationalize their production and trade. Investigates domestic firm characteristics that predict higher GVC participation, and the effect of GVC participation on firm performance. 4. Investment policy and promotion: what is in a government’s toolbox? Summarizes the various policy instruments governments have at their disposal to help attract MNCs to their country and facilitate GVC participation of domestic firms. 5. Integrating countries into GVCs. Draws on a range of case studies to illustrate how governments can develop coherent strategies and policy packages to integrate their countries into GVCs. 6. FDI and GVCs in the wake of COVID-19. Reflects the impact of COVID-19 on FDI and GVCs, the response from multinationals and suppliers, and the implications for GVC reconfiguration. In addition, there are seven case studies that offer more nuanced analysis on the GVC participation in selected countries and sectors: • Five qualitative case studies: Five countries have been selected that managed to use FDI to stimulate GVC participation using a range of approaches. By design, these five countries also cover five different GVC archetypes. These countries are: (1) Kenya (horticulture); (2) Dominican Republic (textiles); (3) Mauritius (tourism); (4) Malaysia (electronics); (5) China (software). • Two quantitative case studies: Rwanda, West-Bengal (India). These use a combination of firm- and transaction level datasets to study firm-level dynamics that explain the role of multinational and domestic firms across GVCs.

An Ocean of Air: Why the Wind Blows and Other Mysteries of the Atmosphere (Read-On)
by Gabrielle WalkerThe science and history of what lies between us and space: “I never knew air could be so interesting.” —Bill Bryson, New York Times bestselling author of The Body: A Guide for OccupantsA flamboyant Renaissance Italian discovers how heavy our air really is (the air filling Carnegie Hall, for example, weighs seventy thousand pounds). A one-eyed barnstorming pilot finds a set of winds that constantly blow five miles above our heads. An impoverished American farmer figures out why hurricanes move in a circle by carving equations with his pitchfork on a barn door. A well-meaning inventor nearly destroys the ozone layer (he also came up with the idea of putting lead in gasoline). A reclusive mathematical genius predicts, thirty years before he’s proven right, that the sky contains a layer of floating metal fed by the glowing tails of shooting stars.We don’t just live in the air; we live because of it. It’s the most miraculous substance on earth, responsible for our food, our weather, our water, and our ability to hear. In this exuberant book, science writer Gabrielle Walker peels back the layers of our atmosphere with the stories of the people who have uncovered its secrets.“A sense of wonder . . . animates Ms. Walker’s high-spirited narrative and speeds it along like a fresh-blowing westerly.” —The New York Times“A fabulous introduction to the world above our heads.” —Daily Mail on Sunday“A lively history of scientists’ and adventurers’ exploration of this important and complex contributor to life on Earth . . . readers will find this informative book to be a breath of fresh air.” —Publishers Weekly
