This book provides a concise introduction to the mathematical aspects of the origin, structure and evolution of the universe. The book begins with a brief overview of observational and theoretical cosmology, along with a short introduction of general relativity. It then goes on to discuss Friedmann models, the Hubble constant and deceleration parameter, singularities, the early universe, inflation, quantum cosmology and the distant future of the universe. This new edition contains a rigorous derivation of the Robertson-Walker metric. It also discusses the limits to the parameter space through various theoretical and observational constraints, and presents a new inflationary solution for a sixth degree potential. This book is suitable as a textbook for advanced undergraduates and beginning graduate students. It will also be of interest to cosmologists, astrophysicists, applied mathematicians and mathematical physicists.
Here is a self-contained exposition of the theory of gravitational solitons and provides a comprehensive review of exact soliton solutions to Einstein's equations. The text begins with a detailed discussion of the extension of the Inverse Scattering Method to the theory of gravitation, starting with pure gravity and then extending it to the coupling of gravity with the electromagnetic field. There follows a systematic review of the gravitational soliton solutions based on their symmetries. These solutions include some of the most interesting in gravitational physics such as those describing inhomogeneous cosmological models, cylindrical waves, the collision of exact gravity waves, and the Schwarzschild and Kerr black holes.
In April 1992, a discovery was made that changed the way we view the world. Dr. George Smoot, distinguished cosmologist and adventurer, whose quest for cosmic knowledge had taken him from the Brazilian rain forest to the South Pole unveiled his momentous discovery, bringing to light the very nature of the universe. For anyone who has ever looked up at the night sky and wondered, for anyone who has ever longed to pull aside the fabric of the universe for a glimpse of what lies behind it. Wrinkles in Time is the story of Smoot's search to uncover the cosmic seeds of the universe. Wrinkles in Time is the Double Helix of cosmology, an intimate look at the inner world of men and women who ask. "Why are we here?" It tells the story of George Smoot's dogged pursuit of the cosmic wrinkles in the frozen wastes of Antarctica, on mountaintops, in experiments borne aloft aboard high-altitude balloons, U-2 spy planes, and finally a space satellite. Wrinkles in Time presents the hard science behind the structured violence of the big bang theory through breathtakingly clear, lucid images and meaningful comparisons. Scientists and nonscientists alike can follow with rapt attention the story of how, in a fiery creation, wrinkles formed in space ultimately to become stars, galaxies, and even greater delicate structures. Anyone can appreciate the implications of a universe whose end is written in its beginnings - whose course developed according to a kind of cosmic DNA, which guided the universe from simplicity and symmetry to ever-greater complexity and structure. As controversial as it may seem today, Wrinkles in Time reveals truths that, in an earlier century, would have doomed its proclaimers to thefiery stake. For four thousand years some people have accepted the Genesis account of cosmic origin; for most of this century, scientists debated two rival scientific explanations known as the steady state and big bang theories. And now, Wrinkles in Time tells what really happened
New Cosmic Horizons tells the extraordinary story of space-based astronomy since the Second World War. Starting with the launch of the V2 rocket in 1946, this book explores the triumphs of space experiments and spacecraft designs and the amazing astronomical results that they have produced. David Leverington examines the fascinating way in which the changing political imperatives of the United States, USSR/Russia and Western Europe have modified their space astronomy programs. He covers all major astronomy missions of the first fifty years of space research: the Soviet Sputnik and American Explorer projects, the subsequent race to the moon, solar and planetary missions, and the wonders of modern astrophysics culminating in the exciting results of the Hubble Space Telescope. Extensively illustrated, New Cosmic Horizons offers amateur and professional astronomers an unusual perspective on the history of astronomy in our time. David Leverington was Design Manager of the GEOS Spacecraft and Meteosat Program Manager for ESA in the 1970s. During his tenure as Engineering Director at British Aerospace in the 1980s, he was responsible for the Giotto spacecraft that intercepted Halley's comet, and the Photon Detector Assembly and solar arrays for the Hubble Space Telescope. He is a Fellow of the Royal Astronomical Society. He lives in Essex, England.
String Theory is our current best candidate for the unification of all fundamental forces, including gravity, in a consistent quantum framework. In this collection of lectures delivered at the Carg se Summer School "String Theory: from Gauge Interactions to Cosmology'', world leading experts provide an up-to-date survey of the latest developments in this topic, including the gauge/gravity correspondence, superstring cosmology and cosmic strings, topological string theory and matrix models, physics beyond the standard model and the landscape of vacua of string theory, conformal field theory and critical phenomena in statistical mechanics. Many more topics are also discussed in shorter contributions by School participants. Written with an emphasis on pedagogy, this volume will be a invaluable resource to students and experts alike.
Knowledge of the structure of the cosmos, Plato suggests, is important in organizing a human community which aims at happiness. This book investigates this theme in Plato's later works, the Timaeus, Statesman, and Laws. Dominic J. O'Meara proposes fresh readings of these texts, starting from the religious festivals and technical and artistic skills in the context of which Plato elaborates his cosmological and political theories, for example the Greek architect's use of models as applied by Plato in describing the making of the world. O'Meara gives an account of the model of which Plato's world is an image; of the mathematics used in producing the world; and of the relation between the cosmic model and the political science and legislation involved in designing a model state in the Laws. Non-specialist scholars and students will be able to access and profit from the book.
This book is a comprehensive and coherent introduction to the role of cosmic strings and other topological defects in the universe. After an introduction to standard cosmological theory and the theory of phase transitions in the early universe, the book then describes, in turn, the properties, formation, and cosmological implications of cosmic strings, monopoles, domain walls and textures. It concludes with a chapter considering the role of topological defects in inflationary universe models. Ample introductory material is included to make the book readily accessible. It will be of interest to graduate students and researchers in particle physics, astrophysics and cosmology.
Do you sometimes wonder why the sky at dusk is filled with color, or how the moon controls the tides? Why do stars twinkle and planets don't? Filled with science and lore, with references to myths, legends, and "high" and popular culture, this "naked-eye" guide (no telescope required) demystifies the celestial in accessible, instructive, and entertaining prose.Upgren tells us why werewolves only come out at night and how to find Betelgeuse. He discusses twilight, the seasons and their causes, our solar system, light and darkness, weather, stars and latitude, the moon, light pollution, and the planets. "Night Has a Thousand Eyes" is the perfect resource for amateur astronomers and meteorologists of all ages who pause to enjoy sunsets and identify constellations on a starry night.
Cometography is the most complete and comprehensive collection of data on comets available. It comes in four self-contained sequential volumes and this, the first, covers ancient times through to the end of the eighteenth century. Cometography uses the most reliable orbits known to determine all the key parameters of each well observed comet. Cometography also provides nontechnical details to help the reader understand how the comet may have influenced various cultures at the time of its appearance. All the information in Cometography has been sourced directly from the original documents, including European monastic histories, Roman, Greek and Muslim texts, Chinese, Japanese and Korean scripts. In many cases, dates of important historical events can be corrected based on the appearance of a comet and identified using this book. Cometography will be valuable to historians of science as well as providing amateur and professional astronomers with a definitive reference on comets through the ages.

Praise for "The Great Beyond": "A marvelous book-very clear, very readable. A brilliant introduction to the math and physics of higher dimensions, from Flatland to superstrings. Its greatest strength is a wealth of fascinating historical narrative and anecdote. I enjoyed it enormously." - Ian Stewart, author of "Flatterland". "A remarkable journey from Plato's cave to the farthest reaches of human thought and scientific knowledge. This mind-boggling book allows readers to dream strange visions of hyperspace, chase light waves, explore Klein's quantum odyssey and Kaluza's cocoon, leap through parallel universes, and grasp the very essence of conscience and cosmos. Buy this book and feed your head." - Clifford Pickover, author of "A Passion for Mathematics". "Halpern looks with a bemused eye at the wildest ideas currently afoot in physics. He takes us into the personal world of those who relish and explore seemingly outlandish notions, and does it with a light, engaging style." - Gregory Benford, author of "Foundation's Fear". "An informative, stimulating, and thoughtful presentation at the very frontiers of contemporary physics.;It is quite on a par with Brian Greene's "The Elegant Universe" or his more recent "The Fabric of the Cosmos", and as such, deserves to receive wide non-specialist coverage among an intelligent, curious, thinking public." - Professor E. Sheldon, "Contemporary Physics".
Astrobiology is a very broad interdisciplinary field covering the
origin, evolution, distribution, and destiny of life in the
universe, as well as the design and implementation of missions for
solar system exploration. A review covering its complete spectrum
has been missing at a level accessible even to the non-specialist.
This book is intended for students interested in the applications of general relativity in astrophysics and cosmology but who would like to avoid mathematical complications. This volume thus combines relativity, astrophysics, and cosmology in a single volume. It provides an introduction to the subject that will enable students to consult more detailed treatises as well as the current literature. For prospective researchers in these fields, the book includes an appendix on differential forms, and an extensive, though not exhaustive list of references. The book is divided into three parts. The section on general relativity gives the case for a curved space-time, presents the mathematical background (tensor calculus, Riemannian geometry), discusses the Einstein equation and its solutions (including black holes, Penrose processes, and similar topics), and considers the energy-momentum tensor for various solutions. The section on relativistic astrophysics discusses stellar contraction and collapse, neutron stars and their equations of state, black holes, and accretion onto collapsed objects. The section on cosmology discusses various cosmological models, observational tests, and scenarios for the early universe.
Die in den Schlick Studien vereinten Texte sind Ergebnisse der rezenten internationalen Forschung zu Leben und Werk Moritz Schlicks. Ein Schwerpunkt besteht in der Dokumentation und Aufarbeitung des Nachlasses. Die Schlick Studien sind als Erganzung und Vertiefung der Arbeit an der Moritz Schlick Gesamtausgabe gedacht und als Reihe auf mehrere Bande hin konzipiert. Beitrage werden sowohl von den Mitarbeitern des Moritz Schlick Projekts wie auch von externen Forschern beigesteuert. Der erste Band enthalt elf Artikel zu den Themen Naturphilosophie und Physik einerseits (Relativitatstheorie, Quantenphysik) sowie allgemein zu Leben und Werk Schlicks andererseits (Schlick als Padagoge, Schlick und Wittgenstein, Schlick und Jacoby, Schlicks Berufung nach Wien etc.). Die Bande der Reihe richten sich an all jene, die rund um die Moritz Schlick Gesamtausgabe weiterfuhrende Literatur zur Moritz-Schlick-Forschung suchen.
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."

(Dr. C.M.Linton, Contemporary Physics, Vol. 46 (3), 2005) "This book centres on the search for life in the Solar System and beyond. It includes an overview of many of the disciplines involved in this field of research, which include astronomy, biology and geology. a ] It was good to see that the astronomy has been kept fairly descriptive and not too mathematical. This keeps the flow of the book. a ] As an overview of the key subjects involved in astrobiology for a university course, I think this book issuccessful." (James Silvester, Astronomy Now, March, 2005) Although, at present there is no firm evidence for extraterrestrial life, enormous progress has been made in recent years, both in our understanding of life on Earth and of the potential for life existing elsewhere in the universe. Life in the Solar System and Beyond embaces aspects form all the osre related fields (astronomy, planetary science, chemistry, biology, and Physics). This excellent and thought-provoking introduction:
David Levy brings these "ghostly apparitions" to life. With fascinating scenarios both real and imagined, he shows how comets have wreaked their special havoc on Earth and other planets. Beginning with ground zero as comets take form, we track the paths their icy, rocky masses take around our universe and investigate the enormous potential that future comets have to directly affect the way we live on this planet and what we might find as we travel to other planets. In this extraordinary volume, David Levy shines his expert light on a subject that has long captivated our imaginations and fears, and demonstrates the need for our continued and rapt attention.
Carl Sagan's many contributions to science and society have been profound and far-reaching, influencing millions of people around the world. He carried out significant research in planetary science, was closely associated with the US space program, created the highly acclaimed television series Cosmos, and was the Pulitzer Prize-winning author of many best-selling popular science books. Carl Sagan's Universe is a fascinating and beautifully illustrated collection of articles by a distinguished team of authors, and covers the many fields of science, education, policy making, and related areas in which Sagan worked. The book is divided into four sections, the first two of which provide an absorbing overview of the US space program (as well as a complementary account of the Russian program), and of the history and current status of the search for extraterrestrial life. The final two sections deal with the importance of science education in the successful development of a technological society, and of the shaping of science policy in tackling the problems facing us today. Also included is a separate chapter by Sagan himself, discussing the place and role of our planet and mankind in the universe. Written in honour of Carl Sagan's many achievements, this book will fascinate and reward anyone interested in planetary science and exploration, the search for extraterrestrial life, or the role of science in the modern world.
This controversial book examines one of the most fundamental questions of modern cosmology: how much matter is there in the Universe? This issue affects theories of the origin and evolution of the Universe as well as its geometrical structure and ultimate fate. The authors address this debate and point out the most likely avenues for determining the actual density of Universe matter in both visible and invisible forms by pulling together evidence from all available sources. They conclude that the balance of arguments presently lies with a density of around twenty percent of the critical density required for the Universe to ultimately recollapse. Written by two eminent cosmologists, this topical and provocative book will be essential reading for all cosmologists and astrophysicists.
The fundamentals of astrochemistry in the gas phase are relatively
well established, in contrast to the special relevance attributed
to processes involving interstellar dust grains - the solid
component of matter diffused among the stars.
The goal of the Daniel Chalonge School on Astrofundamental Physics is to contribute to a theory of the universe (and particularly of the early universe) up to the marks, and at the scientific height of, the unprecedented accuracy, existent and expected, in the observational data. The impressive development of modern cosmology during the last decades is to a large extent due to its unification with elementary particle physics and quantum field theory. The cross-section between these fields has been increasing setting up Astrofundamental Physics. The early universe is an exceptional (theoretical and experimental) laboratory in this new discipline. This NATO Advanced Study Institute provided an up dated understanding, from a fundamental physics and deep point of view, of the progress and key issues in the early universe and the cosmic microwave background: theory and observations. The genuine interplay with large scale structure formation and dark matter problem were discussed. The central focus was placed on the cosmic microwave background. Emphasis was given to the precise inter-relation between fundamental physics and cosmology in these problems, both at the theoretical and experimental/observational levels, within a deep and well defined programme which provided in addition, a careful interdisciplinarity. Special sessions were devoted to high energy cosmic rays, neutrinos in astrophysics, and high energy astrophysics. Deep understanding, clarification, synthesis, careful interdisciplinarity within a fundamental physics framework, were the main goals of the course.
Where did we come from? Before there was life there had to be something to live on - a planet, a solar system. During the past 200 years, astronomers and geologists have developed and tested several different theories about the origin of the solar system and the nature of the Earth. Together, the three volumes that make up A History of Modern Planetary Physics present a survey of these theories. The early twentieth century saw the replacement of the Nebular Hypothesis with the Chamberlain-Moulton theory that the solar system resulted from the encounter of the Sun with a passing star. Fruitful Encounters follows the eventual refutation of the encounter theory and the subsequent revival of a modernised Nebular Hypothesis. Professor Brush also discusses the role of findings from the Apollo space programme, especially the analysis of lunar samples, culminating in the establishment, in the 1980s, of the 'giant impact' theory of the Moon's origin.
The open cluster NGC 6791 is now considered both the oldest and the most metal-rich known. Its age is 8 -10 Gyrs, twice as old as the canonical solar-metallicity cluster M67 (Garnavich et al. 1994; Demarque, Green, & Guenther 1992; Tripicco et al. 1995). That its metallicity is significantly above solar is suggested from moderate-resolution spectroscopy and from a mismatch of its color-magnitude diagram (CMD) with solar-metallicity isochrones. Tripicco et al. (1995) find [Fe/H] = +0.27 to +0.44. The cluster population is rich. In addition to about a dozen red giants and two dozen red horizontal-branch stars, the cluster has several very hot HB stars (Kaluzny & Udalski 1992). Liebert et al. (1994) have shown that the extremely blue stars are mostly sdB/sdO stars and at least 3 or 4 are likely cluster members, the first ever discovered in an open cluster. These may provide the key to the puzzling upturn in ultraviolet flux below 1500A seen in many high-metallicity systems (Burstein et al. 1988; Ferguson et al. & Liebert 1993).
Molecules in the early Universe acted as natural temperature regulators, keeping the primordial gas cool and, in turn, allowing galaxies and stars to be born. Even now, such similarly simple chemistry continues to control a wide variety of the exotic objects that populate our cosmos. What are the tools of the trade for the cosmic chemist? What can they teach us about the Universe we live in? These are the questions answered in this engaging and informative guide, The Chemically Controlled Cosmos. In clear, non-technical terms, and without formal mathematics, we learn how to study and understand the behaviour of molecules in a host of astronomical situations. We study the secretive formation of stars deep within interstellar clouds, the origin of our own Solar System, the cataclysmic deaths of many massive stars that explode as supernovae, and the hearts of active galactic nuclei, the most powerful objects in the Universe. We are given an accessible introduction to a wealth of astrophysics, and an understanding of how cosmic chemistry facilitates the investigation of many of the most exciting questions concerning astronomy today. |
