Ephemeridenrechnung Schritt für Schritt: Sonnenaufgang und Co. bestimmen leicht gemacht
by Dieter RichterDas vorliegende Buch vermittelt die Grundkenntnisse der Ephemeridenrechnung. Ausgehend von den Kepler’schen Gesetzen erfolgt die Berechnung der Koordinaten der Planeten in der Bahnebene. Über eine Anzahl von Transformationen ermittelt man die Koordinaten im Horizontsystem und erhält damit die Winkel, die an einem Teleskop einzustellen sind, um einen bestimmten Planeten zu sehen. Dabei werden das Zweikörper- oder Kepler-Problem und die Berechnung weiterer Parameter, wie die Bahngeschwindigkeit und der Abstand der Planeten von der Sonne, geschlossen hergeleitet, ausführlich erklärt und am Beispiel einzelner Planeten vorgerechnet. Ergänzend dazu, und über das Zweikörperproblem hinausgehend, wird die Berechnung der Mondposition erläutert.Außerdem werden die wichtigsten Einflüsse auf die Planetenbahnen, die im Rahmen der Berechnung als Zweikörperproblem nicht berücksichtigt wurden, erklärt und deren Wirkung auf die Planeten abgeschätzt. Zum besseren Verständnis ist eine Reihe von Beispielen beschrieben und vorgerechnet, bei denen die erworbenen Kenntnisse angewendet werden.Das Buch wendet sich an Studierende der Naturwissenschaften, Physik, Astronomie und an Amateurastronomen sowie naturwissenschaftlich Interessierte, die schon immer einmal erfahren wollten, woher man denn weiß, wann die Sonne aufgeht..
Epic Continent: Adventures in the Great Stories of Europe
by Nicholas JubberThese are the stories that made Europe.Journeying from Turkey to Iceland, award-winning travel writer Nicholas Jubber takes us on a fascinating adventure through our continent's most enduring epic poems to learn how they were shaped by their times, and how they have since shaped us. The great European epics were all inspired by moments of seismic change: The Odyssey tells of the aftermath of the Trojan War, the primal conflict from which much of European civilisation was spawned. The Song of the Nibelungen tracks the collapse of a Germanic kingdom on the edge of the Roman Empire. Both the French Song of Roland and the Serbian Kosovo Cycle emerged from devastating conflicts between Christian and Muslim powers. Beowulf, the only surviving Old English epic, and the great Icelandic Saga of Burnt Njal, respond to times of great religious struggle - the shift from paganism to Christianity. These stories have stirred passions ever since they were composed, motivating armies and revolutionaries, and they continue to do so today.Reaching back into the ancient and medieval eras in which these defining works were produced, and investigating their continuing influence today, Epic Continent explores how matters of honour, fundamentalism, fate, nationhood, sex, class and politics have preoccupied the people of Europe across the millennia. In these tales soaked in blood and fire, Nicholas Jubber discovers how the world of gods and emperors, dragons and water-maidens, knights and princesses made our own: their deep impact on European identity, and their resonance in our turbulent times.

Epic of the Earth: Reading Homer's "Iliad" in the Fight for a Dying World
by Edith HallAn urgent study of Homer&’s Iliad, exposing the beginnings of the ecological disaster we now face and facilitating our understanding of its history The roots of today&’s environmental catastrophe run deep into humanity&’s past. Through this unprecedented reading of Homer&’s Iliad, the award-winning classicist Edith Hall examines how this foundational text both documents the environmental practices of the ancient Greeks and betrays an awareness of the dangers posed by the destruction of the natural landscape. Underlying Homer&’s account of brutal military operations, alliances, and cataclysmic struggle is a palpable understanding that the direction in which humanity was headed could create a world that was uninhabitable. Hall provides unparalleled insight into the ancient origins of climate change and argues that the Iliad exposes the deepest contradictions behind the environmental problems we have created. Indeed, it is possible that some of the violence done to the environment throughout history has been authorized, if not exacerbated, by the celebration of the exploitation of nature in Homer&’s poem. Drawing compelling analogies to contemporary poetry, literature, and film, Hall demonstrates that the Iliad, as a priceless document of the mindset of early humans, can help us understand the long history of ecological degradation and inspire activism to rescue our planet from disaster.
The EPICA-DML Deep Ice Core: A Visual Record (Frontiers in Earth Sciences)
by Sérgio Henrique Faria Sepp Kipfstuhl Anja LambrechtThe line-scan images collected in this book represent the most accurate optical record of Antarctic ice cores ever presented, providing an invaluable resource for glaciologists and climate modellers, as well as a fascinating compilation of ice core images for Antarctica enthusiasts. Global warming and the Earth's past climate are the two main reasons for extracting deep ice cores from Antarctica. Indeed, dust particles, aerosols and other climatic traces deposited on the snow surface, as well as the air trapped in bubbles by compacted snow, produce chronologically ordered strata, making the ice from Antarctica the most accurate and valuable archive of the Earth's climate over the last million years. In addition, the layered structure produced by these strata, when revealed by appropriate methods, provides indispensable information concerning the flow and mechanical stability of the Antarctic ice sheet, allowing us to assess the current and future impact of global warming on the melting of polar ice caps with much greater precision.
Epicurean Simplicity
by Stephanie Mills"In this book, I relate the pleasures, as well as the virtues and difficulties of a perhaps simpler than average North American life." So begins ecological thinker and writer Stephanie Mills's Epicurean Simplicity, a thoughtful paean to living, like Thoreau, a deliberate life.Mills's account of the simple life reaches deep into classical sources of pleasure -- good food, good health, good friends, and particularly the endless delights of the natural world. Her musings about the life she desires -- and the life she has created -- ultimately led her to the third century Greek philosopher Epicurus, whose philosophy was premised on the trustworthiness of the senses, a philosophy that Mills wholeheartedly embraces. While later centuries have come to associate Epicurus's name with hedonism, Mills discovered that he extolled simplicity and prudence as the surest means to pleasure, and his thinking offers an important philosophical touchstone for the book. An overarching theme is the destructiveness of consumerism, and how even a simple life affects a wide range of organisms and adds strain to the earth's systems. The author uses her own experience as an entry point to the discussion with a self-effacing humor and lyrical prose that bring big topics to a personal level.Epicurean Simplicity is beautifully crafted, fluid, inspiring, and enlightening, examining topics of critical importance that affect us all. It celebrates the pleasures, beauty, and fulfillment of a simple life, a goal being sought by Americans from all walks of life, from harried single parents to corporate CEOs. For fans of natural history or personal narrative, for those concerned about social justice and the environment, and for those who have come to know and love Stephanie Mills through her speaking and writing, Epicurean Simplicity is a rare treasure.
Epidemic-logistics Modeling: A New Perspective on Operations Research
by Jing Liang Jie Cao Ming Liu MingJun ChenThis book is the first work to conduct the emergency logistics optimization problem under the epidemic environment (whether natural or man-made), which provides a new perspective for the application of optimization theory. In this book, the research methods involve epidemic dynamics, scenario-based emergency decision-making method, big data which combines the traditional and emerging technologies. The authors take epidemic outbreak as the research object and deeply integrate the epidemic spread model with the optimization model of emergency resource scheduling, which opens up a novel application area of operations research.
Epigenetics in Plants of Agronomic Importance: Fundamentals and Applications
by Raúl Alvarez-Venegas Clelia De la Peña Juan Armando Casas-MollanoOver the past decades, chromatin remodelling has emerged as an important regulator of gene expression and plant defense. This book provides a detailed understanding of the epigenetic mechanisms involved in plants of agronomic importance. The information presented here is significant because it is expected to provide the knowledge needed to develop in the future treatments to manipulate and selectively activate/inhibit proteins and metabolic pathways to counter pathogens, to treat important diseases and to increase crop productivity. New approaches of this kind and the development of new technologies will certainly increase our knowledge of currently known post-translational modifications and facilitate the understanding of their roles in, for example, host-pathogen interactions and crop productivity. Furthermore, we provide important insight on how the plant epigenome changes in response to developmental or environmental stimuli, how chromatin modifications are established and maintained, to which degree they are used throughout the genome, and how chromatin modifications influence each another.
Epistemic Ambivalence: Pentecostalism and Candomblé in a Brazilian City
by Daniel Medeiros de Freitas Carolina Maria Soares Lima Krzysztof Nawratek Bernardo Miranda PataroThis book delves into the complex relationship between religious imaginaries and the perception of space among followers of Candomblé and Pentecostal churches in Belo Horizonte, Brazil's third-largest urban agglomeration. It adopts a dual perspective, examining the broader political, economic, and social dimensions of these religious communities' urbanisation and spatial distribution and their members' individual beliefs and behaviours. Through this approach, the book aims to provide a nuanced and insider's view of these religious positions, challenging our preconceived notions of urban spaces and contributing to the larger discussion of decolonial urban theory and spatialised post-secular thought. This transdisciplinary book will appeal to a broad range of researchers, particularly those interested in urban and religious studies. Its strong spatial perspective makes it attractive to architects and urban designers. It will be of interest to those in human geography, urban planning, design, architecture, political science, religious studies, and culture studies.

An Epistemic Foundation for Scientific Realism: Defending Realism Without Inference To The Best Explanation (Synthese Library #402)
by John WrightThis monograph develops a new way of justifying the claims made by science about phenomenon not directly observable by humans, such as atoms and black holes. It details a way of making inferences to the existence and properties of unobservable entities and states of affairs that can be given a probabilistic justification. The inferences used to establish realist claims are not a form of, and neither do they rely on, inference to the best explanation. Scientific Realism maintains that scientific theories and hypotheses refer to real entities, forces, and relations, even if one cannot examine them. But, there are those who doubt these claims. The author develops a novel way of defending Scientific Realism against a range of influential attacks. He argues that in some cases, at least, we can make probabilistically justifiable inferences from observed data to claims about unobservable, theoretical entities. He shows how this enables us to place some scientific realist claims on a firmer epistemological footing than has previously been the case. This also makes it possible to give a unified set of replies to the most common objections to Scientific Realism. The final chapters apply the developed conceptual apparatus to key cases from the history of science and from recent science. One example concerns realism with respect to atoms. Another looks at inferences from recent astronomical data to conclusions about the size and shape of those parts of the universe lying beyond that which we can observe.
Epistemic Justice, Mindfulness, and the Environmental Humanities: Reflections on Teaching
by Janelle AdsitEpistemic Justice, Mindfulness, and the Environmental Humanities explores how contemplative pedagogies and mindfulness can be used in the classroom to address epistemic and environmental injustice. In recent years, there has been a groundswell of interest in contemplative pedagogies in higher education, with increasing attention from the environmental sciences, environmental humanities, and sustainability studies. Teachers and writers have demonstrated how mindfulness practices can be a key to anti-oppression and anti-racist efforts, both in and out of the classroom. Not all forms of contemplative pedagogy are suited for this anti-colonial and anti-oppressive resistance, however. Simply adopting mindfulness practices in the classroom is not enough to dislodge and dismantle white supremacy in higher education. Epistemic Justice, Mindfulness, and the Environmental Humanities advocates for mindfulness practices that affirm multiple epistemologies and cultural traditions. Written for educators in the environmental humanities and other related disciplines, the chapters interrogate the western uptake of mindfulness practices and suggest anti-colonial and anti-oppressive methods for bringing mindfulness into the classroom. The chapters also discuss what mindfulness practices have to offer to the pursuit of a culturally relevant pedagogy. This highly applied and practical text will be an insightful read for educators in the environmental humanities and across the liberal arts disciplines.
Epistemic Processes: A Basis for Statistics and Quantum Theory
by Inge S. HellandThis book discusses a link between statistical theory and quantum theory based on the concept of epistemic processes – which can be e.g. statistical investigations or quantum mechanical measurements, and refer to processes that are used to gain knowledge about something. The book addresses a range of topics, including a derivation of the Born formula from reasonable assumptions, a derivation of the Schrödinger equation in the one-dimensional case, and a discussion of the Bell inequality from an epistemic perspective. The book describes a possible epistemic foundation of quantum theory. Lastly, it presents a general philosophical discussion of the approach, which, principally speaking, is not restricted to the micro-world. Hence the book can also be seen as a motivation for further research into quantum decision theory and quantum models for cognition. The book will benefit a broad readership, including physicists and statisticians interested in the foundation of their disciplines, philosophers of science and graduate students, and anyone with a reasonably good background in mathematics and an open mind.

The Epochs of Nature
by Georges-Louis Leclerc Jan Zalasiewicz Anne-Sophie Milon Mateusz Zalasiewicz Sverker Sörlin Libby Robin Jacques GrinevaldGeorges-Louis Leclerc, le comte de Buffon's The Epochs of Nature, originally published as Les Époques de la Nature in 1778, is one of the first great popular science books, a work of style and insight that was devoured by Catherine the Great of Russia and influenced Humboldt, Darwin, Lyell, Vernadsky, and many other renowned scientists. It is the first geological history of the world, stretching from the Earth’s origins to its foreseen end, and though Buffon was limited by the scientific knowledge of his era—the substance of the Earth was not, as he asserts, dragged out of the sun by a giant comet, nor is the sun’s heat generated by tidal forces—many of his deductions appear today as startling insights. And yet, The Epochs of Nature has never before been available in its entirety in English—until now. In seven epochs, Buffon reveals the main features of an evolving Earth, from its hard rock substrate to the sedimentary layers on top, from the minerals and fossils found within these layers to volcanoes, earthquakes, and rises and falls in sea level—and he even touches on age-old mysteries like why the sun shines. In one of many moments of striking scientific prescience, Buffon details evidence for species extinction a generation before Cuvier’s more famous assertion of the phenomenon. His seventh and final epoch does nothing less than offer the first geological glimpse of the idea that humans are altering the very foundations of the Earth—an idea of remarkable resonance as we debate the designation of another epoch: the Anthropocene. Also featuring Buffon’s extensive “Notes Justificatives,” in which he offers further evidence to support his assertions (and discusses vanished monstrous North American beasts—what we know as mastodons—as well as the potential existence of human giants), plus an enlightening introduction by editor and translator Jan Zalasiewicz and historians of science Sverker Sörlin, Libby Robin, and Jacques Grinevald, this extraordinary new translation revives Buffon’s quite literally groundbreaking work for a new age.
Equality in Water and Sanitation Services (Earthscan Water Text)
by Oliver Cumming Tom SlaymakerThere is growing acceptance that the progress delivered under the Millennium Development Goal target for drinking water and sanitation has been inequitable. As a result, the progressive reduction of inequalities is now an explicit focus of the Sustainable Development Goal (SDG) targets, adopted in 2015, for universal access to drinking water, sanitation and hygiene (WASH). This shift in focus has implications for the way in which the next generation of WASH policies and programmes will be conceived, designed, financed and monitored. This book provides an authoritative textbook for students, as well as a point of reference for policy-makers and practitioners interested in reducing inequalities in access to WASH services. Four key areas are addressed: background to the human right to water and development goals; dimensions of inequality; case studies in delivering water and sanitation equitably; and monitoring progress in reducing inequality.
Equations and Analytical Tools in Mathematical Physics: A Concise Introduction
by Yichao ZhuThis book highlights a concise and readable introduction to typical treatments of partial differential equations in mathematical physics. Mathematical physics is regarded by many as a profound discipline. In conventional textbooks of mathematical physics, the known and the new pieces of knowledge often intertwine with each other. The book aims to ease readers' struggle by facilitating a smooth transition to new knowledge. To achieve so, the author designs knowledge maps before each chapter and provides comparative summaries in each chapter whenever appropriate. Through these unique ways, readers can clarify the underlying structures among different equations and extend one's vision to the big picture. The book also emphasizes applications of the knowledge by providing practical examples. The book is intended for all those interested in mathematical physics, enabling them to develop a solid command in using partial differential equations to solve physics and engineering problems in a not-so-painful learning experience.
Equations of Mathematical Physics
by A. A. Samarskii A. N. TikhonovMathematical physics plays an important role in the study of many physical processes -- hydrodynamics, elasticity, and electrodynamics, to name just a few. Because of the enormous range and variety of problems dealt with by mathematical physics, this thorough advanced undergraduate- or graduate-level text considers only those problems leading to partial differential equations. Contents:I. Classification of Partial Differential EquationsII. Evaluations of the Hyperbolic TypeIII. Equations of the Parabolic TypeIV. Equations of Elliptic TypeV. Wave Propagation in SpaceVI. Heat Conduction in SpaceVII. Equations of Elliptic Type (Continuation)The authors -- two well-known Russian mathematicians -- have focused on typical physical processes and the principal types of equations dealing with them. Special attention is paid throughout to mathematical formulation, rigorous solutions, and physical interpretation of the results obtained. Carefully chosen problems designed to promote technical skills are contained in each chapter, along with extremely useful appendixes that supply applications of solution methods described in the main text. At the end of the book, a helpful supplement discusses special functions, including spherical and cylindrical functions.
Equations of Motion in Relativistic Gravity (Fundamental Theories of Physics #179)
by Dirk Puetzfeld Claus Lämmerzahl Bernard SchutzThe present volume aims to be a comprehensive survey on the derivation of the equations of motion, both in General Relativity as well as in alternative gravity theories. The topics covered range from the description of test bodies, to self-gravitating (heavy) bodies, to current and future observations.Emphasis is put on the coverage of various approximation methods (e.g., multipolar, post-Newtonian, self-force methods) which are extensively used in the context of the relativistic problem of motion. Applications discussed in this volume range from the motion of binary systems -- and the gravitational waves emitted by such systems -- to observations of the galactic center. In particular the impact of choices at a fundamental theoretical level on the interpretation of experiments is highlighted.This book provides a broad and up-do-date status report, which will not only be of value for the experts working in this field, but also may serve as a guideline for students with background in General Relativity who like to enter this field.

It explains the connection of the probability theory of extreme processes with examples from the sciences of earthquake observation. In contrast to many views, the present analysis takes into account the complete population of all measurement data of the magnitudes from 0 to the measured maximum
Equilibrium and Nonequilibrium Aspects of Phase Transitions in Quantum Physics (Springer Theses)
by Ricardo PueblaIn this book, the equilibrium and nonequilibrium properties of continuous phase transitions are studied in various systems, with a special emphasis on understanding how well-established universal traits at equilibrium may be extended into the dynamic realm, going beyond the paradigmatic Kibble–Zurek mechanism of defect formation. This book reports on the existence of a quantum phase transition in a system comprising just a single spin and a bosonic mode (the quantum Rabi model). Though critical phenomena are inherent to many-body physics, the author demonstrates that this small and ostensibly simple system allows us to explore the rich phenomenology of phase transitions, both in- and out-of-equilibrium. Moreover, the universal traits of this quantum phase transition may be realized in a single trapped-ion experiment, thus avoiding the need to scale up the number of constituents. In this system, the phase transition takes place in a suitable limit of system parameters rather than in the conventional thermodynamic limit – a novel notion that the author and his collaborators have dubbed the finite-component system phase transition. As such, the results gathered in this book will open promising new avenues in our understanding and exploration of quantum critical phenomena.
Equilibrium Compound Nucleus Post-Fission Theory
by Qing-Biao Shen Ye TianThis book proposes and develops the equilibrium compound nucleus post-fission theory, a powerful tool for studying the fission process and making numerical calculations of post-fission nuclear data. It begins with a detailed historical background on fission theory and covers fundamental concepts, such as the Bohr-Wheeler formula and time dependent nuclear density functional theory.The authors explain the kinematics of heavy-ion collisions and develop a heavy-ion spherical optical model. They also present the theoretical methods for calculating the yield, kinetic energy distribution, and angular distribution of fission fragments in the initial state of fission. In addition, readers are provided with the method for calculating the prompt neutron and prompt gamma-ray data as well as the proportion of the isomeric state nucleus and independent yield from the initial yield of the fission fragments. Using the nuclear decay data of the fission products, a method for calculating the cumulative yield and decay heat of the fission fragments is also given. A fission delayed neutron simplification model is proposed and the theoretical method for calculating the total contribution of three fission channels to post-fission nuclear data is provided.This book concludes with a step-by-step guide on numerical calculations for post-fission nuclear data and a Fortran program for optimizing the best theoretical model parameters. It is ideal for both junior and senior researchers in nuclear physics, as well as graduate students who are interested learning about the subject. Given the current interest in post-fission and the tremendous experimental and theoretical efforts in studying it, this book serves as a timely and comprehensive resource for the nuclear physics community.
Equilibrium Statistical Physics: Phases, Phase Transitions, and Topological Phases
by Marc Baus Carlos F. TejeroThis is a textbook which gradually introduces the student to the statistical mechanical study of the different phases of matter and to the phase transitions between them. Throughout, only simple models of both ordinary and soft matter are used but these are studied in full detail. The subject is developed in a pedagogical manner, starting from the basics, going from the simple ideal systems to the interacting systems, and ending with the more modern topics. The textbook provides the student with a complete overview, intentionally at an introductory level, of the theory of phase transitions. All equations and deductions are included.
