This book provides an accessible introduction to loop quantum gravity and some of its applications, at a level suitable for undergraduate students and others with only a minimal knowledge of college level physics. In particular it is not assumed that the reader is familiar with general relativity and only minimally familiar with quantum mechanics and Hamiltonian mechanics. Most chapters end with problems that elaborate on the text, and aid learning. Applications such as loop quantum cosmology, black hole entropy and spin foams are briefly covered. The text is ideally suited for an undergraduate course in the senior year of a physics major. It can also be used to introduce undergraduates to general relativity and quantum field theory as part of a 'special topics' type of course.

In Assembling Life, David Deamer addresses questions that are the cutting edge of research on the origin of life. For instance, how did non-living organic compounds assemble into the first forms of primitive cellular life? What was the source of those compounds and the energy that produced the first nucleic acids? Did life begin in the ocean or in fresh water on terrestrial land masses? Could life have begun on Mars? The book provides an overview of conditions on the early Earth four billion years ago and explains why fresh water hot springs are a plausible alternative to salty seawater as a site where life can begin. Deamer describes his studies of organic compounds that were likely to be available in the prebiotic environment and the volcanic conditions that can drive chemical evolution toward the origin of life. The book is not exclusively Earth-centric, but instead considers whether life could begin elsewhere in our solar system. Deamer does not propose how life did begin, because we can never know that with certainty. Instead, his goal is to understand how life can begin on any habitable planet, with Earth so far being the only known example.

The third edition of this successful textbook is fully updated and includes important recent developments in cosmology. It begins with an introduction to cosmology and general relativity, and goes on to cover the mathematical models of standard cosmology. The physical aspects of cosmology, including primordial nucleosynthesis, the astroparticle physics of inflation, and the current ideas on structure formation are discussed. Alternative models of cosmology are reviewed, including the model of Quasi-Steady State Cosmology, which has recently been proposed as an alternative to Big Bang Cosmology.

The two pillars of modern physics are general relativity and quantum field theory, the former describes the large scale structure and dynamics of space-time, the latter, the microscopic constituents of matter. Combining the two yields quantum field theory in curved space-time, which is needed to understand quantum field processes in the early universe and black holes, such as the well-known Hawking effect. This book examines the effects of quantum field processes back-reacting on the background space-time which become important near the Planck time (10-43 sec). It explores the self-consistent description of both space-time and matter via the semiclassical Einstein equation of semiclassical gravity theory, exemplified by the inflationary cosmology, and fluctuations of quantum fields which underpin stochastic gravity, necessary for the description of metric fluctuations (space-time foams). Covering over four decades of thematic development, this book is a valuable resource for researchers interested in quantum field theory, gravitation and cosmology.

Since the dawn of humanity, men have attempted to divine the nature of the heavens. The first astronomers mapped the movement of the seasons and used the positions of the constellations for augurs and astrology. Today, the search goes ever deeper into the nature of reality and life itself. In this accessible overview, astrophysicist J.P. McEvoy tells the story of how our knowledge of the cosmos has developed. He puts in context many of the greatest discoveries of all time and many of the dominant personalities: Aristotle, Copernicus, and Isaac Newton, and as we approach the modern era, Einstein, Eddington, and Hawking.

Scientific Cosmology and International Orders shows how scientific ideas have transformed international politics since 1550. Allan argues that cosmological concepts arising from Western science made possible the shift from a sixteenth-century order premised upon divine providence to the present order centred on economic growth. As states and other international associations used scientific ideas to solve problems, they slowly reconfigured ideas about how the world works, humanity's place in the universe, and the meaning of progress. The book demonstrates the rise of scientific ideas across three cases: natural philosophy in balance of power politics, 1550-1815; geology and Darwinism in British colonial policy and international colonial orders, 1860-1950; and cybernetic-systems thinking and economics in the World Bank and American liberal order, 1945-2015. Together, the cases trace the emergence of economic growth as a central end of states from its origins in colonial doctrines of development and balance of power thinking about improvement.

This book deals with neutrino physics and astrophysics - a field in which some of the most exciting recent developments in particle physics, astrophysics and cosmology took place. The book is the most up-to-date, comprehensive and self-contained treatment of key issues in neutrino physics. It discusses all the topics vital to the understanding of the nature of neutrinos such as what they are, how to describe them, how they behave in nature, and the roles that neutrinos play in shaping our Universe. The book provides comprehensive discussions, both experimental and theoretical, with relevant mathematical details, on neutrino oscillations, extra-terrestrial as well as terrestrial neutrinos and the relic neutrinos. It also discusses many implications of current experimental data on reactor, accelerator, atmospheric, solar and supernova neutrinos with future perspectives. The book starts with an introduction to field theory and gauge theory which is accessible even to advanced undergraduate students, with helpful appendices, and it also provides pedagogical but sufficiently detailed reviews of supernova physics and cosmology, in particular the Cosmic Microwave Background Radiation. It aims to provide all the technical details necessary for the professionals in the field and to be an almost exhaustive reference for neutrino physicists with over 1000 references.

The advent of sensitive high-resolution observations of the cosmic microwave background radiation and their successful interpretation in terms of the standard cosmological model has led to great confidence in this model's reality. The prevailing attitude is that we now understand the Universe and need only work out the details. In this book, Sanders traces the development and successes of Lambda-CDM, and argues that this triumphalism may be premature. The model's two major components, dark energy and dark matter, have the character of the pre-twentieth-century luminiferous aether. While there is astronomical evidence for these hypothetical fluids, their enigmatic properties call into question our assumptions of the universality of locally determined physical law. Sanders explains how modified Newtonian dynamics (MOND) is a significant challenge for cold dark matter. Overall, the message is hopeful: the field of cosmology has not become frozen, and there is much fundamental work ahead for tomorrow's cosmologists.

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist. Fascinating from first to last--this is a book that has already prompted the attention and admiration of some of the most prominent scientists and mathematicians.

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.

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.

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.

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."

Cometography is a multi-volume catalog of every comet observed throughout history. It uses the most reliable orbits known to determine the distances from the Earth and Sun at the time a comet was discovered and last observed, as well as the largest and smallest angular distance to the Sun, most northerly and southerly declination, closest distance to the Earth, and other details to enable the reader to understand the physical appearance of each well-observed comet. Volume 4 provides a complete discussion of each comet seen from 1933 to 1959. It includes physical descriptions made throughout each comet's apparition. The comets are listed in chronological order, and each listing includes complete references to publications relating to the comet. This book is the most complete and comprehensive collection of comet data available, and provides amateur and professional astronomers, and historians of science, with a definitive reference on comets through the ages.

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.

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."

This book is a simple, non-technical introduction to cosmology, explaining what it is and what cosmologists do. Peter Coles discusses the history of the subject, the development of the Big Bang theory, and more speculative modern issues like quantum cosmology, superstrings, and dark matter.

People worldwide are questioning the materialistic, mechanistic scientific pradigm that has been the dominant cosmology for the past one hundred years or so. The purpose of The New Paradigm is to provide a philosophical foundation for a spiritual cosmology that can incorporate both modern science and ancient wisdom. This is a paradigm that many have hoped would arise to usher in the predicted New Age of elevated spiritual awareness and understanding. The New Paradigm offers insights into the nature of people and their relationship to the one universal Spirit they have called God. This philosophical treatise makes a strong case to the effect that people are created from the substance of Spirit and hence are powerful spiritual beings who have forgotten their true nature and origin.
