The immensity of the cosmos, the richness of the Universe, the limits of space and time: these are the themes of Cosmic Odyssey, which takes the reader on imaginary journeys through the past, present and future of our universe.

What are you? Obviously, you are a person with human ancestors that can be plotted on a family tree, but you have other identities as well. According to evolutionary biologists, for example, you are a member of the species Homo sapiens. To a microbiologist, though, you are a collection of cells, each of which has its own cellular ancestry. A geneticist might point out that besides these identities, you can be understood as a gene-replication machine, which can be plotted on a "genetic tree." Finally a physicist will give a rather different answer to the identity question: you can be understood as a collection of atoms, each of which has a very long history. Some have been around since the Big Bang, and others are the result of nuclear fusion that took place within a star. Not only that, but most of your atoms belonged to other living things before joining you. From your atoms' point of view, then, you are just a way station on a multibillion-year-long journey. You: A Natural History offers a multi-disciplinary investigation of your hyper-extended family tree, going all the way back to the Big Bang. And while your family tree may contain surprises, your hyper-extended history contains some truly amazing stories. As the result of learning more about who and what you are, and about how you came to be here, you will likely see the world around you with fresh eyes. You will also become aware of all the one-off events that had to take place for your existence to be possible: stars had to explode, the earth had to be hit 4.5 billion years ago by a planetesimal and 65 million years ago by an asteroid, microbes had to engulf microbes, the African savanna had to undergo climate change, and of course, any number of your direct ancestors had to meet and mate. It is difficult, on becoming aware of just how contingent your own existence is, not to feel very lucky to be part of our universe.

Cosmic Perspectives is a collection of essays that details modern cosmology and its relationship to the development of human civilization. Written by leading astronomers, cosmologists and historians, these fourteen essays cover a wide range of subjects. These include the place of astronomy in China, frontiers in cosmology, the dark matter problem and the origin of life. This is an engaging collection of facts, written in nontechnical language, which encourages the reader to explore the scientific heritage of various cultures, the current problems of observational astronomy, the unsolved mysteries of evolution and the use of astronomy in fiction.

In our small corner of the universe, we know how some matter behaves most of the time and what even less of it looks like, and we have some good guesses about where it all came from. But we really have no clue what's going on. In fact, we don't know what about 95% of the universe is made of. So what happens when a cartoonist and a physicist walk into this strange, mostly unknown universe? Jorge Cham and Daniel Whiteson gleefully explore the biggest unknowns, why these things are still mysteries, and what a lot of smart people are doing to figure out the answers (or at least ask the right questions). While they're at it, they helpfully demystify many complicated things we do know about, from quarks and neutrinos to gravitational waves and exploding black holes. With equal doses of humour and delight, they invite us to see the universe as a vast expanse of mostly uncharted territory that's still ours to explore. This is a book for fans of Brian Cox and What If. This highly entertaining highly illustrated book is perfect for anyone who's curious about all the great mysteries physicists are going to solve next.

Simple chemistry governs a host of the exotic objects that populate our cosmos. For example, molecules in the early Universe acted as natural temperature regulators, keeping the primordial gas cool and, in turn, allowing galaxies and stars to form. What are the tools of the trade for the cosmic chemist and what can they teach us about the Universe we live in? These are the questions answered in this engaging and informative guide--the first book for nonspecialists on molecular astrophysics. In clear, nontechnical terms, and without formal mathematics, Hartquist and Williams show how to study and understand the behavior of molecules in a host of astronomical situations. Readers will learn about 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. This book provides an accessible introduction to a wealth of astrophysics, and an understanding of how cosmic chemistry allows the investigation of many of the most exciting questions concerning astronomy today.

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 recent research into gravitational collapse, and several examples of collapse models are investigated in detail.

This highly interdisciplinary 2007 book highlights many of the ways in which chemistry plays a crucial role in making life an evolutionary possibility in the universe. Cosmologists and particle physicists have often explored how the observed laws and constants of nature lie within a narrow range that allows complexity and life to evolve and adapt. Here, these anthropic considerations are diversified in a host of new ways to identify the most sensitive features of biochemistry and astrobiology. Celebrating the classic 1913 work of Lawrence J. Henderson, The Fitness of the Environment for Life, this book looks at the delicate balance between chemistry and the ambient conditions in the universe that permit complex chemical networks and structures to exist. It will appeal to a broad range of scientists, academics, and others interested in the origin and existence of life in our universe.

The standard cosmological picture of our Universe emerging from a 'big bang' leaves open many fundamental questions which string theory, a unified theory of all forces of nature, should be able to answer. This 2007 text was the first dedicated to string cosmology, and contains a pedagogical introduction to the basic notions of the subject. It describes the possible scenarios suggested by string theory for the primordial evolution of our Universe. It discusses the main phenomenological consequences of these scenarios, stresses their differences from each other, and compares them to the more conventional models of inflation. The book summarises over 15 years of research in this field and introduces advances. It is self-contained, so it can be read by astrophysicists with no knowledge of string theory, and high-energy physicists with little understanding of cosmology. Detailed and explicit derivations of all the results presented provide a deeper appreciation of the subject.

The lectures that four authors present in this volume investigate core topics related to the accelerated expansion of the Universe. Accelerated expansion occured in the ?36 very early Universe - an exponential expansion in the in ationary period 10 s after the Big Bang. This well-established theoretical concept had rst been p- posed in 1980 by Alan Guth to account for the homogeneity and isotropy of the observable universe, and simultaneously by Alexei Starobinski, and has since then been developed by many authors in great theoretical detail. An accelerated expansion of the late Universe at redshifts z< 1 has been disc- ered in 1998; the expansion is not slowing down under the in uence of gravity, but is instead accelerating due to some uniformly distributed, gravitationally repulsive substance accounting for more than 70% of the mass-energy content of the U- verse, which is now known as dark energy. Its most common interpretation today is given in terms of the so-called CDM model with a cosmological constant .

What will happen to the near-Earth space environment? How can we ensure the survival of future scientific, commercial and military satellites and space stations? This book addresses the questions that must be asked as debris in space around the Earth--from dust particles to rocket casings, and even radioactive materials--becomes a critical problem. In this volume, many specialists from around the world address the issues, problems, and policies concerned with the preservation of near-Earth space. Their articles cover the technical aspects, and the economic and legal issues concerned, including the enforcement and monitoring of international agreements and the resolution of disputes. This clearly written and well illustrated survey offers the professional and concerned nonspecialist an authoritative and comprehensive review of the problems with and solutions to space debris.

From a physicist at the top of his field comes this rigorous yet accessible book that takes us back in time to before the birth of the universe.

Between the years 1890 and 1924, the dominant view of the universe suggested a cosmology largely foreign to contemporary ideas. First, astronomers believed they had confirmed that the sun was roughly in the centre of the Milky Way galaxy. Second, considerable evidence indicated that the size of the galaxy was only about one-third the value now accepted by today's astronomers. Third, it was thought that interstellar space was completely transparent, that there was no absorbing material between the stars. Fourth, astronomers believed that the universe was composed of numerous star systems comparable to the Milky Way galaxy. The method that provided this picture and came to dominate cosmology was 'statistical' in nature, because it was based on the counts of stars and their positions, motions, brightnesses and stellar spectra. Professor Paul describes the rise of this statistical cosmology in light of developments in nineteenth-century astronomy and explains how this cosmology set the stage for many of the most significant developments of twentieth-century astronomy.

Spectacular observational breakthroughs by recent experiments, and particularly the WMAP satellite, have heralded a new epoch of CMB science forty years after its original discovery. Taking a physical approach, the authors probe the problem of the ???darkness??? of the Universe: the origin and evolution of dark energy and matter in the cosmos. Starting with the observational background of modern cosmology, they provide an up-to-date and accessible review of this fascinating yet complex subject. Topics discussed include the kinetics of the electromagnetic radiation in the Universe, the ionization history of cosmic plasmas, the origin of primordial perturbations in light of the inflation paradigm, and the formation of anisotropy and polarization of the CMB. This timely and accessible review will be valuable to advanced students and researchers in cosmology. The text highlights the progress made by recent experiments, including the WMAP satellite, and looks ahead to future CMB experiments.

The amount of cosmological data has dramatically increased in the past decades due to an unprecedented development of telescopes, detectors and satellites. Efficiently handling and analysing new data of the order of terabytes per day requires not only computer power to be processed but also the development of sophisticated algorithms and pipelines.
Aiming at students and researchers the lecture notes in this volume explain in pedagogical manner the best techniques used to extract information from cosmological data, as well as reliable methods that should help us improve our view of the universe.

Now in its 4th edition, this classic text presents a quantitative understanding of a range of astrophysical concepts. Emphasizing physical concepts, the book outlines cosmic events but does not portray them in detail. Instead, it provides a series of astrophysical sketches showing how to obtain quantitative insights into the structure and evolution of stars, the dynamics of cosmic gases, the large-scale behavior of the universe, and the origins of life. Nearly every part of the text has been reconsidered and rewritten for the new edition; new sections cover recent developments, and the remainder has been revised and brought up to date.

This work fills a gap in the Platonic literature. Though much has been written on Plato's ethics, his cosmology has received little attention in recent times, and its importance for his ethical thought has remained virtually unexplored. Focusing especially on the Timaeus, Philebus, Politicus and Laws, the book reveals a strongly symbiotic relation between cosmic and human order. It is argued that in his late period Plato presents a picture of an organic universe, endowed with structure and intrinsic value. Such a universe may serve as an ethical paradigm for humans even in the absence of good political institutions. But human beings in turn have responsibility for improving the overall quality of the universe, of which they are a part. The book breaks new ground both in its systematic presentation of Plato's late cosmology and in its highlighting of the close connections between that and the development of his ethics.

Critical acclaim for John Gribbin

""The master of popular science.""
--"Sunday Times" (London)

""Gribbin explains things very well indeed, and there's not an equation in sight.""
--David Goodstein, "The New York Times Book Review" (on Almost Everyone's Guide to Science)

""Gribbin breathes life into the core ideas of complexity science, and argues convincingly that the basic laws, even in biology, will ultimately turn out to be simple.""
--"Nature" magazine (on Deep Simplicity)

""Gribbin takes us through the basics of chaos theory] with his customary talent for accessibility and clarity. His] arguments are driven not by impersonal equations but by a sense of wonder at the presence in the universe and in nature of simple, self-organizing harmonies underpinning all structures, whether they are stars or flowers.""
--"Sunday Times" (London) (on Deep Simplicity)

""In the true quantum realm, Gribbin remains the premier expositor of the latest developments.""

We have just concluded a remarkable century: the 1917 publication of Einstein's general theory of relativity, Carnegie astronomer Edwin Hubble's 1929 discovery of the expansion of the universe, evidence for the existence of dark matter, and the discovery of a mysterious dark energy, which is causing the universe to speed up its expansion. This comprehensive volume reviews the current theory and measurement of various parameters related to the evolution of the universe. Topics include inflation, string theory, the history of cosmology in the context of current measurements being made of the Hubble constant, the matter density, and dark energy, including observational results from the Sloan, Digital Sky Survey, Keck, Magellan, cosmic microwave background experiments, Hubble space telescope and Chandra. With chapters by leading authorities in the field, this book is a valuable resource for graduate students and professional research astronomers.

Clusters of galaxies are the largest and most massive collapsed systems in the Universe, and as such they are valuable probes of cosmological structure and galaxy evolution. The advent of extensive galaxy surveys, large ground-based facilities, space-based missions such as HST, Chandra and XMM-Newton and detailed numerical simulations makes now a particularly exciting time to be involved in this field. The review papers in this volume span the full range of current research in this area, including theoretical expectations for the growth of structure, survey techniques to identify clusters, metal production and the intracluster medium, galaxy evolution in the cluster environment and group-cluster connections. With contributions from leading authorities in the field, this volume is appropriate both as an introduction to this topic for physics and astronomy graduate students, and as a reference source for professional research astronomers.

This book provides an introduction to Quantum Chromodynamics (QCD), the theory of strong interactions. It covers in full detail both the theoretical foundations and the experimental tests of the theory. Although the experimental chapters focus on recent measurements, the subject is placed into historical perspective by also summarizing the steps which lead to the formulation of QCD. Measurements are discussed as they were performing by the LEP experiments at CERN, or at hadron-hadron and lepton-hadron colliders such as the TEVATRON at Fermilab and HERN at DESY. Emphasis is placed on high energy tests of QCD, such as measurements of the strong coupling constant, investigations of the non-abelian structure of the underlying gauge group, determinations of nucleon structure functions, and studies of the non-perturbative hadronization process. This excellent text gives a detailed overview of how QCD developed in the 20th century and where we stand with respect to a quantitative understanding after the turn of the millenium. The text is intended for graduate and postgraduate students as well as researchers, and includes numerous problems and solutions.

Neither Arkadii nor Boris Strugatskii had originally intended to make a living in writing. Arkadii dreamed of becoming an astronomer, but his wartime experience and training led him to work as a translator and editor of Japanese literature. Boris intended to become a physicist, trained as an astronomer, and ended up as a computer specialist at Pulkovo Observatory. This common thread of astronomy turns out to be fantastically important for understanding their works, as their most important ones are experiments in cosmology, and their shared expertise is instrumental in their construction of literary hellscapes. This book explores how the Strugatskiis' cosmological explorations are among the most fundamental elements of their art. It examines also how these explorations connect to their predecessors in the Russian literary tradition-particularly to the poetry of Pushkin.
