Paradigms of the Large-Scale Universe
by Grigor A. GurzadyanDynamical systems provide powerful methods for the study of profound properties of many-dimensional nonlinear systems. In this unique book, the authors offer a consistent geometrical treatment of observational cosmology from the concepts of the theory of dynamical systems. The dynamics of clusters of galaxies differ drastically from stellar dynamics, thus requiring a mathematical approach to large-scale problems. Since mathematical techniques are not a familiar tool in this field, a full summary of the elementary ideas of differential geometry, ergodic theory and catastrophe theory are also considered in this exploratory text. Readership: Mathematicians, astrophysicists, and cosmologists, as well as anyone interested in the many subject disciplines related to geometrical and topological aspects of the large-scale universe.

Paradise Lost and the Cosmological Revolution
by Dennis DanielsonThis volume brings John Milton's Paradise Lost into dialogue with the challenges of cosmology and the world of Galileo, whom Milton met and admired: a universe encompassing space travel, an earth that participates vibrantly in the cosmic dance, and stars that are "world[s] / Of destined habitation. " Milton's bold depiction of our universe as merely a small part of a larger multiverse allows the removal of hell from the center of the earth to a location in the primordial abyss. In this wide-ranging work, Dennis Danielson lucidly unfolds early modern cosmological debates, engaging not only Galileo but also Copernicus, Tycho, Kepler, and the English Copernicans, thus placing Milton at a rich crossroads of epic poetry and the history of science.

Paradox
by Jim Al-KhaliliA fun and fascinating look at great scientific paradoxes. Throughout history, scientists have come up with theories and ideas that just don't seem to make sense. These we call paradoxes. The paradoxes Al-Khalili offers are drawn chiefly from physics and astronomy and represent those that have stumped some of the finest minds. For example, how can a cat be both dead and alive at the same time? Why will Achilles never beat a tortoise in a race, no matter how fast he runs? And how can a person be ten years older than his twin? With elegant explanations that bring the reader inside the mind of those who've developed them, Al-Khalili helps us to see that, in fact, paradoxes can be solved if seen from the right angle. Just as surely as Al-Khalili narrates the enduring fascination of these classic paradoxes, he reveals their underlying logic. In doing so, he brings to life a select group of the most exciting concepts in human knowledge. Paradox is mind-expanding fun.
Paradoxes in Aerohydrodynamics
by Shakhbaz A. YershinThis book, on the general topic of hydroaerodynamics, investigates anumber of exciting applications in this field, addressing specifically issuesthat allow seemingly paradoxical issues to be dealt with. The first part is devoted to the study of channel flows, in particularthe lateral flow of a viscous and viscous-plastic liquid in a ring channelformed by coaxial cylinders. Specifically, the problem of dissipation ofmechanical energy in channel flows of highly viscous liquids is addressed andsolved. Furthermore, the mechanism leading to hydrodynamic erosion inintra-field pipelines (known as "channelized effect") is identified. Subsequently, a theory for channel flows with mass transfer through porous wallsis developed. In the second part, viscous liquid free flows (jets) are investigated. In particular, a dispersion law for turbulent flow is derived and the existenceof dynamic invariance in wake flows of variable density is demonstrated. The third part presents new insights from both theoretical andexperimental research into concentrated vortex structure formation anddevelopment. The conditions for the existence of Taylor-Goertler vortices aredetermined and the mechanism for their formation is described. Last but notleast, the theory of vortex rings, a particularly interesting problem inhydroaerodynamics, is introduced in the last section of this book. Care has been taken, when selecting original theoretical problems ofinterest, to make the link with related topics in the published literature. Atthe same time, all experimental research described in this book is given ameaningful physical interpretation and corroborated by suitable theoreticalmodels and computations.
Paradoxes in Probability Theory
by William EckhardtParadoxes provide a vehicle for exposing misinterpretations and misapplications of accepted principles. This book discusses seven paradoxes surrounding probability theory. Some remain the focus of controversy; others have allegedly been solved, however the accepted solutions are demonstrably incorrect. Each paradox is shown to rest on one or more fallacies. Instead of the esoteric, idiosyncratic, and untested methods that have been brought to bear on these problems, the book invokes uncontroversial probability principles, acceptable both to frequentists and subjectivists. The philosophical disputation inspired by these paradoxes is shown to be misguided and unnecessary; for instance, startling claims concerning human destiny and the nature of reality are directly related to fallacious reasoning in a betting paradox, and a problem analyzed in philosophy journals is resolved by means of a computer program.
Parallax: The Race to Measure the Cosmos (Dover Books On Astronomy Ser.)
by Alan W. HirshfeldIn the dramatic tradition of the best-selling Longitude, Parallax charts the historical path of observational astronomy's most daunting challenge: measuring the distance to a star. The greatest scientific minds applied themselves in vain to the problem across the millennia, beginning with the ancient Greeks. Not until the nineteenth century would three astronomers, armed with the best telescopes of the age, race to conquer this astronomical Everest—their contest ending in a virtual dead heat. Against a sweeping backdrop filled with kidnappings, dramatic rescue, swordplay, madness, and bitter rivalry, Alan Hirshfeld brings to life the heroes of this remarkable story. Meet the destitute boy plucked from a collapsed building who becomes the greatest telescope maker the world has ever seen; the hot-tempered Dane whose nose is lopped off in a duel over mathematics; the merchant's apprentice forced to choose between the lure of money and his passion for astronomy; and the musician who astounds the world by discovering a new planet from his own backyard. Generously illustrated with diagrams, period engravings, and paintings, Parallax is an unforgettable tale that illuminates the distinctly human side of science.

Parallel Lives of Astronomers: Percival Lowell and Edward Emerson Barnard (Springer Biographies)
by William SheehanUsing the "Parallel Lives" approach adopted by the Greek biographer Plutarch, noted historian of astronomy William Sheehan contrasts the lives and research careers of two famous astronomers, Percival Lowell and Edward Emerson Barnard. Drawing on vast archival materials and hitherto unpublished source materials, Sheehan documents in detail the contributions of these two late 19th and early 20th astronomers. Living at a time when controversies about Mars peaked, when great observatories were being built, and when research increasingly turned away from the Solar System toward the stellar and extra-galactic universe, these observers made spectacular contributions to astronomy. Their work still inspires, and continues in Perseverance rover's explorations of the surface of Mars carrying forward Lowell's dream of showing that Mars may once have been "the abode of life," and in Barnard's pioneering wide-angle photographs of the Milky Way which first showed the sweep, majesty and complexity of the Galaxy. The work of decades of research and writing, Sheehan has produced what is likely to become the definitive work on these two great astronomers. "Parallel Lives marks an important contribution to the history of astronomy. The book is masterful and inventive. William Sheehan could hardly have chosen two more compelling—or contrasting—personalities to analyze in this fascinating dual biography." - David Baron, author of American Eclipse and The Martians, and former Chair in Astrobiology at the Library of Congress. "Sheehan has united scientific acumen, detailed historical research, penetrating insight into character, and narrative virtuosity—and adapted it all to an ancient Greek model—a remarkable achievement!" - Michael Armstrong, Assoc. Prof. Emeritus of Classics, Hobart and William Smith Colleges, Geneva NY William Sheehan's many books include the authoritative biography The Immortal Fire Within: The Life and Work of Edward Emerson Barnard and (with Jim Bell) Discovering Mars: A History of Observation and Exploration of the Red Planet, which has been called the "gold standard of books on Mars" (Michio Kaku).
Parallel Minds: Discovering the Intelligence of Materials
by Laura TripaldiInsights into the intelligence throughout the natural and technical environment, in the fabric of our devices and dwellings, in our clothes, and under our skin.Is there a way to understand the materials that surround us not as passive objects, but as other intelligences interacting with our own? In Parallel Minds, expert in materials science and nanotechnology Laura Tripaldi delivers not only detailed insights into the properties and emergent behaviors of matter as revealed by state-of-the-art chemistry, synthetic biology, and nanotech, but also a rich philosophical reflection that crosses the frontier between nature and culture, where the most cutting-edge scientific syntheses resonate with ancient myth. The result is a technomaterial bestiary full of unexpected encounters with &“strange minds&”—from cobwebs to kevlar and carbon fibre, from centaurs to amoebas to arachnids, from polycephalic slime to resonating plasmons, from viruses to golems. Parallel Minds reveals the intelligence at large throughout the natural and technical environment, in the fabric of our devices and dwellings, in our clothes, and even under our skin. Full of lateral ideas and unexpected images, Tripaldi&’s book imbues the study and synthesis of materials with a new urgency. For not only do the materials that surround us participate actively in the construction of the world in which we live, but harnessing their ability to interact intelligently with their environment could be the key to the future of our species.

Parameter Redundancy and Identifiability (Chapman & Hall/CRC Interdisciplinary Statistics)
by Diana ColeStatistical and mathematical models are defined by parameters that describe different characteristics of those models. Ideally it would be possible to find parameter estimates for every parameter in that model, but, in some cases, this is not possible. For example, two parameters that only ever appear in the model as a product could not be estimated individually; only the product can be estimated. Such a model is said to be parameter redundant, or the parameters are described as non-identifiable. This book explains why parameter redundancy and non-identifiability is a problem and the different methods that can be used for detection, including in a Bayesian context. Key features of this book: Detailed discussion of the problems caused by parameter redundancy and non-identifiability Explanation of the different general methods for detecting parameter redundancy and non-identifiability, including symbolic algebra and numerical methods Chapter on Bayesian identifiability Throughout illustrative examples are used to clearly demonstrate each problem and method. Maple and R code are available for these examples More in-depth focus on the areas of discrete and continuous state-space models and ecological statistics, including methods that have been specifically developed for each of these areas This book is designed to make parameter redundancy and non-identifiability accessible and understandable to a wide audience from masters and PhD students to researchers, from mathematicians and statisticians to practitioners using mathematical or statistical models.

Paranoid Science: The Christian Right's War on Reality (Goldstein-Goren American Jewish History)
by Antony AlumkalExplores the Christian Right’s fierce opposition to science, explaining how and why its leaders came to see scientific truths as their enemyFor decades, the Christian Right’s high-profile clashes with science have made national headlines. From attempts to insert intelligent design creationism into public schools to climate change denial, efforts to “cure” gay people through conversion therapy, and opposition to stem cell research, the Christian Right has battled against science. How did this hostility begin and, more importantly, why has it endured?Antony Alumkal provides a comprehensive background on the war on science—how it developed and why it will continue to endure. Drawing upon Richard Hofstadter’s influential 1965 essay “The Paranoid Style in American Politics,” Antony Alumkal argues that the Christian Right adopts a similar paranoid style in their approach to science. Alumkal demonstrates that Christian Right leaders see conspiracies within the scientific establishment, with scientists not only peddling fraudulent information, but actively concealing their true motives from the American public and threatening to destroy the moral foundation of society. By rejecting science, Christian Right leaders create their own alternative reality, one that does not challenge their literal reading of the Bible. While Alumkal recognizes the many evangelicals who oppose the Christian Right’s agenda, he also highlights the consequences of the war on reality—both for the evangelical community and the broader American public. A compelling glimpse into the heart of the Christian Right’s anti-science agenda, Paranoid Science is a must-read for those who hope to understand the Christian Right’s battle against science, and for the scientists and educators who wish to stop it.
