Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    This exquisite book, now in softcover, is the result of that bold and immensely personal project. Through the accompanying essay, Brandenburg shares his innermost thoughts and passions as he witnesses the cycle of nature near his home in the northwoods of Minnesota.Brandenburg also contributes new photos and an Epilog that illustrates and discusses the devastating summer wind storm that wreaked havoc on the locations photographed for the original project.

    Line drawings and black-and-white photographs.

    Over 100 illustrations spotlight dozens of different varieties, including Oak, Willow, Pine, and Palmetto. Topics include shading techniques, composition, portraying shadow and light, and approaches to outlining.Author and illustrator Victor Perard, a graduate of the École des Beaux-Arts in Paris, was an art instructor at New York City's Cooper Union for twenty years. This informative volume reflects his extensive teaching experience and provides practical advice for artists at every level.

    As miraculous a feat of nature as the snowflakes has been, have we ever been truly able to appreciate this infinitesimal wonder in all its crystalline glory? Art of the Snowflake, as much a work of art as a testament to science, reveals how one of the snowflake's most inspired photographers came to such intimate knowledge of his craft and its fleeting focus. Beautiful pictures illustrate Kenneth Libbrecht's story of the microphotography of snow crystals, from the pioneering work of Wilson Bentley in the 1890s right up to Ken's own innovations in our age of digital images. A breathtaking look at the works of art that melt in an instant, this is a book to flip through and savor, season after season.

    They loom over museum halls, thunder through movies, and are a fundamental part of our collective imagination. In My Beloved Brontosaurus, the dinosaur fanatic Brian Switek enriches the childlike sense of wonder these amazing creatures instill in us. Investigating the latest discoveries in paleontology, he breathes new life into old bones.Switek reunites us with these mysterious creatures as he visits desolate excavation sites and hallowed museum vaults, exploring everything from the sex life of Apatosaurus and T. rex’s feather-laden body to just why dinosaurs vanished. (And of course, on his journey, he celebrates the book’s titular hero, “Brontosaurus”—who suffered a second extinction when we learned he never existed at all—as a symbol of scientific progress.)With infectious enthusiasm, Switek questions what we’ve long held to be true about these beasts, weaving in stories from his obsession with dinosaurs, which started when he was just knee-high to a Stegosaurus. Endearing, surprising, and essential to our understanding of our own evolution and our place on Earth, My Beloved Brontosaurus is a book that dinosaur fans and anyone interested in scientific progress will cherish for years to come.

    But despite the hype, Tyrannosaurus and the other tyrannosaurs are fascinating animals in their own right, and are among the best-studied of all dinosaurs.Tyrannosaurs started small, but over the course of 100 million years evolved into the giant carnivorous bone-crushers that continue to inspire awe in palaeontologists, screenplay writers, sci-fi novelists and the general public alike. Tyrannosaurus itself was truly impressive; it topped six tons, was more than 12m (40 feet) long, and had the largest head and most powerful bite of any land animal in history.The Tyrannosaur Chronicles tracks the rise of these dinosaurs, and presents the latest research into their biology, showing off more than just their impressive statistics - tyrannosaurs had feathers and fought and even ate each other. This book presents the science behind this research; it tells the story of the group through their anatomy, ecology and behaviour, exploring how they came to be the dominant terrestrial predators of the Mesozoic and, in more recent times, one of the great icons of biology.

    He had a talent for drawing and an interest in birds, and he would spend the next thirty-five years traveling to the remotest regions of his new country–often alone and on foot–to render his avian subjects on paper. The works of art he created gave the world its idea of America. They gave America its idea of itself. Here Richard Rhodes vividly depicts Audubon’s life and career: his epic wanderings; his quest to portray birds in a lifelike way; his long, anguished separations from his adored wife; his ambivalent witness to the vanishing of the wilderness. John James Audubon: The Making of an American is a magnificent achievement.

    Sixty-six million years ago, the Earth’s most fearsome creatures vanished. Today they remain one of our planet’s great mysteries. Now The Rise and Fall of the Dinosaurs reveals their extraordinary, 200-million-year-long story as never before.In this captivating narrative (enlivened with more than seventy original illustrations and photographs), Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field—naming fifteen new species and leading groundbreaking scientific studies and fieldwork—masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy. Captivating and revelatory, The Rise and Fall of the Dinosaurs is a book for the ages.Brusatte traces the evolution of dinosaurs from their inauspicious start as small shadow dwellers—themselves the beneficiaries of a mass extinction caused by volcanic eruptions at the beginning of the Triassic period—into the dominant array of species every wide-eyed child memorizes today, T. rex, Triceratops, Brontosaurus, and more. This gifted scientist and writer re-creates the dinosaurs’ peak during the Jurassic and Cretaceous, when thousands of species thrived, and winged and feathered dinosaurs, the prehistoric ancestors of modern birds, emerged. The story continues to the end of the Cretaceous period, when a giant asteroid or comet struck the planet and nearly every dinosaur species (but not all) died out, in the most extraordinary extinction event in earth’s history, one full of lessons for today as we confront a “sixth extinction.”Brusatte also recalls compelling stories from his globe-trotting expeditions during one of the most exciting eras in dinosaur research—which he calls “a new golden age of discovery”—and offers thrilling accounts of some of the remarkable findings he and his colleagues have made, including primitive human-sized tyrannosaurs; monstrous carnivores even larger than T. rex; and paradigm-shifting feathered raptors from China.An electrifying scientific history that unearths the dinosaurs’ epic saga, The Rise and Fall of the Dinosaurs will be a definitive and treasured account for decades to come.

    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

    At the same time as climate change has assumed this status, it has become a topic more likely to be included in a church sermon. Indeed, while once considered the concern of scientific institutions, climate change is now increasingly incorporated into faith-based initiatives with even Pope Francis weighing in, issuing an encyclical on the subject as explained in chapter 16 by Paul Driessen. There are those who believe Pope Francis, and admire another climate change exponent, Al Gore – who marketed An Inconvenient Truth with comment, ‘the fact of global warming is not in question’ and that ‘its consequences for the world we live in will be disastrous if left unchecked’. And then there are the die-hard sceptics who dare to doubt. Many claim that these climate sceptics and their support base have an undue political influence, successfully thwarting attempts to implement necessary public policy change. This book is a collection of chapters by so-called climate sceptics. Each writer was asked to write on an aspect of the topic in which they are considered to have some expertise. None of them deny that climate change is real, but instead, they point out how extremely complex the topic of Earth’s climate is, with some of the contributors also querying the, often generally accepted, solutions. As you will see, this is not a book with just one message, except perhaps that there is a need for more scrutiny of the data, and of our own prejudices. This book’s reason for being is to give pause for thought, and to throw some alternative ideas and considerations into the mix.

    Harlen Bretz walked the dry scabland channels of eastern Washington in the 1920s, it dawned on him that he was viewing a landscape sculpted by water. Lots of water. A flood of catastrophic proportions. Glacial Lake Missoula and Its Humongous Floods tells the gripping tale of a huge Ice Age lake that drained suddenly--not just once but repeatedly--and reshaped the landscape of the Northwest. The narrative follows the path of the floodwaters as they raged from western Montana across the Idaho Panhandle, then scoured through eastern Washington and down the Columbia Gorge to the Pacific Ocean. This is also the story of geologists grappling with scientific controversy--"of how personalities, pride, and prejudice sometimes superseded scientific evidence."

    This new edition brings the classic work back to life.In the late eighteenth century, mineralogist Abraham Gottlob Werner devised a standardized color scheme that allowed him to describe even the subtlest of chromatic differences with consistent terminology. His scheme was then adapted by an Edinburgh flower painter, Patrick Syme, who used the actual minerals described by Werner to create the color charts in the book, enhancing them with examples from flora and fauna.In the pre-photographic age, almost all visual details had to be captured via the written word, and scientific observers could not afford ambiguity in their descriptions. Werner's handbook became an invaluable resource for naturalists and anthropologists, including Charles Darwin, who used it to identify colors in nature during his seminal voyage on the HMS Beagle. Werner's terminology lent both precision and lyricism to Darwin's pioneering writings, enabling his readers to envision a world they would never see.Werner's Nomenclature of Colours is a charming artifact from the golden age of natural history and global exploration. This beautiful pocket-size facsimile is certain to delight and inform a new generation of artists and scientists.
