This well known and widely used landmark text explores the universal spontaneous generation of magnetic fields in astronomical bodies and the agitation of the bodies by those fields. The general properties of magnetic fields, their appearance throughout the astronomical universe, and the havoc they wreak are described in simple physical terms so as to define the broad scientific problem presented by magnetic fields. Then, with the physical problems clearly in mind, the theoretical effects are demonstrated with formal mathematical illustrations from the basic electromagnetic equations.

Carl Sagan once noted that there is only one generation that gets to see things for the first time. We are in the midst of such a time right now, standing on the threshold of discovery in the young and remarkable field of X-ray astronomy. In The Restless Universe, astronomer Eric Schlegel offers readers an informative survey of this cutting-edge science. Two major space observatories launched in the last few years--NASA's Chandra and the European Newton--are now orbiting the Earth, sending back a gold mine of data on the X-ray universe. Schlegel, who has worked on the Chandra project for seven years, describes the building and launching of this space-based X-ray observatory. But the book goes far beyond the story of Chandra. What Schlegel provides here is the background a nonscientist would need to grasp the present and follow the future of X-ray astronomy. He looks at the relatively brief history of the field, the hardware used to detect X-rays, the satellites--past, present, and future--that have been or will be flown to collect the data, the way astronomers interpret this data, and, perhaps most important, the insights we have already learned as well as speculations about what we may soon discover. And throughout the book, Schlegel conveys the excitement of looking at the universe from the perspective brought by these new observatories and the sharper view they deliver. Drawing on observations obtained from Chandra, Newton, and previous X-ray observatories, The Restless Universe gives a first look at an exciting field which significantly enriches our understanding of the universe.

From the cutting edge of science and living spirituality: a guide to understanding our identity and purpose in the world * Explains how we can evolve consciously, become connected with each other, and flourish on this planet * "From the time when the conscious universe was a preposterous notion to today, when it's a cutting-edge idea full of promise for your future, Ervin Laszlo has been its staunch champion." - Deepak Chopra, author of You Are the Universe. For the outdated mainstream paradigm the world is a giant mechanism functioning in accordance with known and knowable laws and regularities. The new paradigm emerging in science offers a different concept: The world is an interconnected, coherent whole, and it is informed by a cosmic intelligence. We are conscious beings who emerge and co-evolve as complex, cosmic-intelligence in-formed vibrations in the Akashic Field of the universe. Ervin Laszlo and his collaborators from the forefront of science, cosmology, and spirituality show how the re-discovery of who we are and why we are here integrates seamlessly with the new emerging worldview in the sciences, revealing a way forward for humanity on this planet. Offering a guidepost to orient this evolution, Laszlo examines the nature of consciousness in the universe, showing how our bodies and minds act as transmitters of consciousness from the intelligence of the cosmos and how understanding science's new concept of the world enables us to re-discover our identity and our purpose in our world. With bold vision and forward thinking, Laszlo and his contributors Maria Sagi, Kingsley L. Dennis, Emanuel Kuntzelman, Dawna Jones, Shamik Desai, Garry Jacobs, and John R. Audette outline the new idea of the world and of ourselves in the world. They help us discover how we can overcome these divisive times and blossom into a new era of peace, coherence, connection, and global wellbeing.

Aimed at advanced undergraduates, this self-contained textbook covers the key ideas of special and general relativity together with their applications. The textbook introduces students to basic geometric concepts, such as metrics, connections and curvature, before examining general relativity in more detail. It shows the observational evidence supporting the theory, and the description general relativity provides of black holes and cosmological space-times. The textbook is in full colour, with numerous worked examples and exercises with solutions. Key points and equations are highlighted for easy identification, and each chapter ends with a summary list of important concepts and results. This textbook provides the essential background for an up-to-date discussion of modern observational cosmology. Each chapter builds on the previous one as concepts are developed, making it ideal for self-study.

Can animals be persons? To this question, scientific and philosophical consensus has taken the form of a resounding, 'No!' In this book, Mark Rowlands disagrees. Not only can animals be persons, many of them probably are. Taking, as his starting point, John Locke's classic definition of a person, as "a thinking intelligent being, that has reason and reflection, and can consider itself the same thinking thing, in different times and places," Rowlands argues that many animals can satisfy all of these conditions. A person is an individual in which four features coalesce: consciousness, rationality, self-awareness and other-awareness, and many animals are such individuals. Consciousness-something that is like to have an experience-is widely distributed through the animal kingdom. Many animals are capable of both causal and logical reasoning. Many animals are also self-aware, since a form of self-awareness is essentially built into the possession of conscious experience. And some animals are capable of a kind of awareness of the minds of others, quite independently of whether they possess a theory of mind. This is not just a book about animals, however. As well as being fascinating in their own right, animals, as Claude Levi-Strauss once put it, are "good to think." In this seamless interweaving of the empirical study of animal minds with philosophy and its history, this book makes a powerful case for the idea that reflection on animals allows us to better understand each of these four pillars of personhood, and so illuminates what means for any individual-animal or human-to be conscious, rational, self- and other-aware.

An encapsulation in nine numbers of all that modern astronomy has learnt about the universe. These cosmic numbers appear to be independent characteristics of our universe and include its age, the Hubble constant (a measure of its rate of expression), and the density of matter in the universe. Only one of the nine numbers is known with real precision, and four of them only poorly known. Difficult ideas like the origin of the elements, the General Theory of Relativity, quantum theory, and the standard model of particle physics, ideas which underpin modern cosmology, are explained in a simple way. While most of what we know has been learnt during the 20th century, Rowan-Robinson provides a historical perspective, paying homage to the achievements of the Greeks, Renaissance astronomers, and the age of Newton. The book ends with predictions of when all nine numbers will be accurately known.

Dark energy, the mysterious cause of the accelerating expansion of the universe, is one of the most important fields of research in astrophysics and cosmology today. Introducing the theoretical ideas, observational methods and results, this textbook is ideally suited to graduate courses on dark energy, and will also supplement advanced cosmology courses. Providing a thorough introduction to this exciting field, the textbook covers the cosmological constant, quintessence, k-essence, perfect fluid models, extra-dimensional models, and modified gravity. Observational research is reviewed, from the cosmic microwave background to baryon acoustic oscillations, weak lensing and cluster abundances. Every chapter ends with problems, with full solutions provided, and any calculations are worked through step-by-step.

How a great enigma of astronomy was solved Astronomers have determined that our universe is 13.7 billion years old. How exactly did they come to this precise conclusion? How Old Is the Universe? tells the incredible story of how astronomers solved one of the most compelling mysteries in science and, along the way, introduces readers to fundamental concepts and cutting-edge advances in modern astronomy. The age of our universe poses a deceptively simple question, and its answer carries profound implications for science, religion, and philosophy. David Weintraub traces the centuries-old quest by astronomers to fathom the secrets of the nighttime sky. Describing the achievements of the visionaries whose discoveries collectively unveiled a fundamental mystery, he shows how many independent lines of inquiry and much painstakingly gathered evidence, when fitted together like pieces in a cosmic puzzle, led to the long-sought answer. Astronomers don't believe the universe is 13.7 billion years old-they know it. You will too after reading this book. By focusing on one of the most crucial questions about the universe and challenging readers to understand the answer, Weintraub familiarizes readers with the ideas and phenomena at the heart of modern astronomy, including red giants and white dwarfs, cepheid variable stars and supernovae, clusters of galaxies, gravitational lensing, dark matter, dark energy and the accelerating universe-and much more. Offering a unique historical approach to astronomy, How Old Is the Universe? sheds light on the inner workings of scientific inquiry and reveals how astronomers grapple with deep questions about the physical nature of our universe.

The 2015 centenary of the publication of Einstein's general theory of relativity, and the first detection of gravitational waves have focused renewed attention on the question of whether Einstein was right. This review of experimental gravity provides a detailed survey of the intensive testing of Einstein's theory of gravity, including tests in the emerging strong-field dynamical regime. It discusses the theoretical frameworks needed to analyze gravitational theories and interpret experiments. Completely revised and updated, this new edition features coverage of new alternative theories of gravity, a unified treatment of gravitational radiation, and the implications of the latest binary pulsar observations. It spans the earliest tests involving the Solar System to the latest tests using gravitational waves detected from merging black holes and neutron stars. It is a comprehensive reference for researchers and graduate students working in general relativity, cosmology, particle physics and astrophysics.

This volume, the proceedings of IAU Symposium 363, addresses the astrophysical implications of gravitational wave and electromagnetic observations of neutron stars. It covers the state of the art understanding of mergers of binary neutron stars producing short gamma-ray bursts, and the most powerfully magnetic varieties of neutron stars, magnetars. Encapsulating both observations and modelling, the contributions address extreme transient events including kilonovae, afterglows, magnetar giant flares, and fast radio bursts. By exploring the intersection of studies of isolated neutron stars and binary system synthesis and merging, this collection sets the scene for interpreting exciting results pertaining to powerful x-ray, gamma-ray, and gravitational wave transients to be acquired in the next decade and beyond. IAU S363 will be an asset for astronomers seeking a broad and interdisciplinary overview of neutron stars, their gravitational waves and electromagnetic emission.

It has been firmly established over the last quarter century that cosmic dust plays important roles in astrochemistry. The consequences of these roles affect the formation of planets, stars and even galaxies. Cosmic dust has been a controversial topic but there is now a considerable measure of agreement as to its nature and roles in astronomy, and its initiation of astrobiology. The subject has stimulated an enormous research effort, with researchers in many countries now involved in laboratory research and in ab initio computations. This is the first book devoted to a study of the chemistry of cosmic dust, presenting current thinking on the subject distilled from many publications in surface and solid-state science, and in astronomy. The authors discuss the nature of dust, its formation and evolution, the chemistry it can promote on its surfaces, and the consequences of these functions. The purpose of this book is to review current understanding and to indicate where future work is required. Mainly intended for researchers in the field of astrochemistry, the book could also be used as the basis of a course for postgraduate students who have an interest in astrochemistry.

1919 hat das Preussische Ministerium fur Wissenschaft, Kunst und Volksbildung die Akte "Einsteins Relativitatstheorie" angelegt. Der Autor, selbst Wissenschaftshistoriker, hat sie 1961 gefunden und zusammen mit anderen inzwischen identifizierten "Einstein"-Akten aus deutschen Archiven als Quellmaterial fur dieses faszinierende Buch gewahlt. Eingeteilt in drei Abschnitte: "Im Kaiserreich"-"In der Weimarer Republik"-"Das dritte Reich" zeichnet das Buch das Einsteinbild nach, zeigt auf, wie der Wissenschaftler immer starker durch die Ereignisse dieser turbulenten Jahre zu einer politischen Figur wurde und tragt Neues zum besseren Verstehen fur Einsteins rigorosen Bruch mit Deutschland bei. Damit fullt der Autor eine wichtige Lucke in der Einsteinliteratur.

In der Neuauflage kommt noch ein Abschnitt hinzu, in dem der Autor bisher unbekanntes Material zu den FBI- und CIC-Berichten uber Einsteins angebliche Kontakte zur KPD und Komintern vorlegt. Des weiteren wird Einsteins Mitarbeit in der Volkerbundkommission erstmals in Tiefe behandelt."

Der Glaube an die Gesetzmassigkeit der Natur, das Streben, allge- meine und universell gultige Gesetze zu finden, und die Hoffnung - oder sogar Erwartung -, der Wahrheit uber die Wirklichkeit naher zu kommen, haben ihren Grund in einer besonderen persoenlichen Welt- sicht, die tiefere Wurzeln als alle naturwissenschaftlichen Disziplinen und philosophischen Systeme hat. Der persoenliche Kontakt mit einem schoepferischen Geist ist anre- gend, er verstarkt den Drang nach Verstehen und vergroessert die Be- friedigung, wenn Aufklarung zuteil wurde. Wenn dies durch Mathema- tik oder eine theoretische Disziplin erfolgt, ist diese Befriedigung dem Vergnugen verwandt, das man an schoener Musik oder anderen wahren Kunstwerken empfindet. Es war mein grosses Gluck, an der Universitat Berlin studieren zu koennen, als Einstein, von Laue und Planck dort lehrten. Ihr Werk pragte mich stark und dauerhaft. Ich erhielt Einblick in ihr Denken, die ihnen eigenen Methoden und schliesslich in ihre Persoenlichkeit. Ich moechte einige meiner Erinnerungen in der Hoffnung wiedergeben, ihre Ansichten und ihre Persoenlichkeit fur die, die sie kannten, lebendig zu erhalten und fur alle anderen erstehen zu lassen.

Our world is nested, both physically and socially, and at each level we find innovations that are necessary for the next. Consider: atoms combine to form molecules, molecules combine to form single-celled organisms; when people come together, they build societies. Physics has gone far in mapping the basic mechanics of the simplest things and the dynamics of the overall nesting, as have biology and the social sciences for their fields. But what can we say about this beautifully complex whole? How does one stage shape another, and what can we learn about human existence through understanding an enlarged field of creation and being? In Quarks to Culture, Tyler Volk answers these questions, revealing how a universal natural rhythm-building from smaller things into larger, more complex things-resulted in a grand sequence of twelve fundamental levels across the realms of physics, biology, and culture. He introduces the key concept of "combogenesis," the building-up from combination and integration to produce new things with innovative relations. He explores common themes in how physics and chemistry led to biological evolution, and biological evolution to cultural evolution. Volk also provides insights into linkages across the sciences and fields of scholarship, and presents an exciting synthesis of ideas along a sequence of things and relations, from physical to living to cultural. The resulting inclusive natural philosophy brings clarity to our place in the world, offering a roadmap for those who seek to understand big history and wrestle with questions of how we came to be.

Im Alter von 21 Jahren hat W. Pauli einen Handbuchartikel zur Relativitatstheorie verfasst, der bis heute gelesen und zitiert wird. Er ist wohl der beruhmteste Text zum Thema und wurde nicht zuletzt von A. Einstein begeistert gewurdigt. Die vorliegende Neuausgabe enthalt den Originalartikel sowie weitere, teilweise recht ausfuhrliche Erganzungen, die Pauli im Jahre 1956 fur die englische Ausgabe schrieb. Eine Reihe von Anmerkungen des Herausgebers dienen daruber hinaus als Lesehilfen und zeigen Verbindungen zu modernen Entwicklungen auf."

What is life? Where do we come from and how did we evolve? What is the universe and how was it formed? What is the nature of the material world? How does it work? How and why do we think? What does it mean to be human? How do we know? There are many different versions of our creation story. This book tells the version according to modern science. It is a unique account, starting at the Big Bang and travelling right up to the emergence of humans as conscious intelligent beings, 13.8 billion years later. Chapter by chapter, it sets out the current state of scientific knowledge: the origins of space and time; energy, mass, and light; galaxies, stars, and our sun; the habitable earth, and complex life itself. Drawing together the physical and biological sciences, Baggott recounts what we currently know of our history, highlighting the questions science has yet to answer.

'Totally engrossing' - STEPHEN KING on The Ninth Metal THE FINAL BOOK IN PERCY'S CRITICALLY CLAIMED COMET CYCLE SERIES! The comet, Cain, came from beyond our solar system, its debris containing elements unknown. Now, in the isolated region of Fairbanks, Alaska, the skies shift and stretch as an interstellar dust cloud seeds the atmosphere. When a plane shudders its way through pulpy, swirling, bruise-shaped clouds, lit with sudden cracks of lightning, the sky opens and the aircraft vanishes...but only for a minute. When the flight lands, everyone on board and in the community will be changed forever. Chuck Bridges, a local DJ and conspiracy theorist, was on board and later reported dead to his family, but not before proclaiming that something inside the clouds was speaking to him. Now his son, Theo, must chase down answers to the mystery his father unlocked. He'll find himself at odds with Sophie Chen, an agent with a shadowy employer desperate to secure the black box from the airplane, as well as Rolf Wagner, a widowed sheriff investigating a series of increasingly strange and unsettling reports. And then there is Joanna Straub, a contractor reconstructing a top-secret government lab active during WWII and shuttered deep within the nearby White Mountains. The answer to the comet's origin is about to be unveiled, and its impact on Earth is more treacherous and sublime than humanity could imagine. 'Take one part dystopia, one part sci-fi, two parts apocalypse, then ride them roughshod through a bleak and bloody western, and it still wouldn't get close to what Ben Percy does here, which is blow open the core of humanity's dark heart.' - Marlon James, Booker Prize-winning author of Black Leopard, Red Wolf, on The Ninth Metal 'The Stephen King of science fiction.' - Margaret Stohl, New York Times bestselling author, on The Ninth Metal 'Audacious and intelligent and exactly what I was dying to read.' - Victor LaValle, author of The Changeling, on The Ninth Metal 'This standout combination of science and psychology is sure to wow SF fans.'

Obwohl der Mundigkeitsbegriff seine herausragende Stellung in der erziehungswissenschaftlichen Diskussion mittlerweile eingebusst hat, ist er immer noch als Erziehungsziel gegenwartig. Wer von Mundigkeit redet, meint - mal mehr, mal weniger explizit - das Verantwortung begrundende Freiheitsvermoegen, sich selbst regieren zu koennen. Angenommen, die moderne Hirnforschung hatte Recht und Freiheit ware tatsachlich nur eine Illusion, musste mit der Unmoeglichkeit von Freiheit und Verantwortung konsequenterweise auch der Mundigkeitsbegriff verworfen werden. Kants Idee der Freiheit zeigt, warum Freiheit trotz (neuronaler) Determination widerspruchsfrei gedacht werden kann. Diese Fundierung des Mundigkeitsbegriffs in der Idee der Freiheit schrankt zugleich auch die Bandbreite dessen ein, was Mundigkeit sein kann und nimmt dem Begriff so seine Beliebigkeit.

The role that neutrinos have played in the evolution of the Universe is the focus of one of the most fascinating research areas that has stemmed from the interplay between cosmology, astrophysics and particle physics. In this self-contained book, the authors bring together all aspects of the role of neutrinos in cosmology, spanning from leptogenesis to primordial nucleosynthesis, their role in CMB and structure formation, to the problem of their direct detection. The book starts by guiding the reader through aspects of fundamental neutrino physics, such as the standard cosmological model and the statistical mechanics in the expanding Universe, before discussing the history of neutrinos in chronological order from the very early stages until today. This timely book will interest graduate students and researchers in astrophysics, cosmology and particle physics, who work with either a theoretical or experimental focus.

Magnetic fields pervade the universe and play an important role in many astrophysical processes. However, they require specialised observational tools, and are challenging to model and understand. This volume provides a unified view of magnetic fields across astrophysical and cosmological contexts, drawing together disparate topics that are rarely covered together. Written by the lecturers of the XXV Canary Islands Winter School, it offers a self-contained introduction to cosmic magnetic fields on a range of scales. The connections between the behaviours of magnetic fields in these varying contexts are particularly emphasised, from the relatively small and close ranges of the Sun, planets and stars, to galaxies and clusters of galaxies, as well as on cosmological scales. Aimed at young researchers and graduate students, this up-to-date review uniquely brings together a subject often tackled by disconnected communities, conveying the latest advances as well as highlighting the limits of our current understanding.

Physical phenomena in astrophysics and cosmology involve gravitational collapse in a fundamental way. The final fate of a massive star when it collapses under its own gravity at the end of its life cycle is one of the most important questions in gravitation theory and relativistic astrophysics, and is the foundation of black hole physics. General relativity predicts that continual gravitational collapse gives rise to a space-time singularity. Quantum gravity may take over in such regimes to resolve the classical space-time singularity. This book investigates these issues, and shows how the visible ultra-dense regions arise naturally and generically as an outcome of dynamical gravitational collapse. It will be of interest to graduate students and academic researchers in gravitation physics, fundamental physics, astrophysics, and cosmology. It includes a detailed review of research into gravitational collapse, and several examples of collapse models are investigated in detail.
