While we may take our air for granted, Earth was not always an oxygenated planet. How did it become this way? "Oxygen" is the most current account of the history of atmospheric oxygen on Earth. Donald Canfield--one of the world's leading authorities on geochemistry, earth history, and the early oceans--covers this vast history, emphasizing its relationship to the evolution of life and the evolving chemistry of the Earth. With an accessible and colorful first-person narrative, he draws from a variety of fields, including geology, paleontology, geochemistry, biochemistry, animal physiology, and microbiology, to explain why our oxygenated Earth became the ideal place for life.Describing which processes, both biological and geological, act to control oxygen levels in the atmosphere, Canfield traces the records of oxygen concentrations through time. Readers learn about the great oxidation event, the tipping point 2.3 billion years ago when the oxygen content of the Earth increased dramatically, and Canfield examines how oxygenation created a favorable environment for the evolution of large animals. He guides readers through the various lines of scientific evidence, considers some of the wrong turns and dead ends along the way, and highlights the scientists and researchers who have made key discoveries in the field.Showing how Earth's atmosphere developed over time, "Oxygen" takes readers on a remarkable journey through the history of the oxygenation of our planet.

    The great thinkers of that extraordinary age, including Isaac Newton, Johannes Kepler, and Christopher Wren, are shown in the context in which they lived and worked. We learn of the correspondences they kept with their equally passionate colleagues and come to understand the unique collaborative climate that fostered virtuoso discoveries in the areas of medicine, astronomy, mathematics, biology, chemistry, botany, geography, and engineering.  Ingenious Pursuits brilliantly chronicles the true intellectual revolution that continues to shape our very understanding of ourselves, and of the world around us.

    Pairing Charles Darwin and a rare species of barnacle as her unlikely protagonists, Rebecca Stott has written an absorbing work of history that guides readers through the treacherous shoals of nineteenth-century biology. Beginning her scientific detective story in the 1820s, even before Darwin's Beagle voyage, Stott examines the mystery of why Darwin waited over two decades between formulating his pivotal theory of natural selection and publishing it. Lavishly illustrated, filled with riddles and concepts that challenge our notion of Victorian science, Darwin and the Barnacle is a thrilling account of how genius proceeds through indirection—and how one small item of curiosity contributed to history's most spectacular scientific breakthrough.

    They have done so since before recorded history. Flowers are used to celebrate all-important occasions, to express love, and are also the basis of global industries. Americans buy ten million flowers a day and perfumes are a worldwide industry worth $30 billion dollars annually. Yet, we know little about flowers, their origins, bizarre sex lives, or how humans relate and depend upon them.Stephen Buchmann takes us along on an exploratory journey of the roles flowers play in the production of our foods, spices, medicines, perfumes, while simultaneously bringing joy and health. Flowering plants continue to serve as inspiration in our myths and legends, in the fine and decorative arts, and in literary works of prose and poetry. Flowers seduce us—and animals, too—through their myriad shapes, colors, textures, and scents. And because of our extraordinary appetite for more unusual and beautiful “super flowers,” plant breeders have created such unnatural blooms as blue roses and black petunias to cater to the human world of haute couture fashion. In so doing, the nectar and pollen vital to the bees, butterflies, and bats of the world, are being reduced. Buchmann explains the unfortunate consequences, and explores how to counter them by growing the right flowers. Here, he integrates fascinating stories about the many colorful personalities who populate the world of flowers, and the flowers and pollinators themselves, with a research-based narrative that illuminates just why there is, indeed, a Reason for Flowers.

    "One of today's best popularizers of science." —Kirkus Reviews.Loyal readers of the monthly "Universe" essays in Natural History magazine have long recognized Neil deGrasse Tyson's talent for guiding them through the mysteries of the cosmos with stunning clarity and almost childlike enthusiasm. Here, Tyson compiles his favorite essays across a myriad of cosmic topics. The title essay introduces readers to the physics of black holes by explaining the gory details of what would happen to your body if you fell into one. "Holy Wars" examines the needless friction between science and religion in the context of historical conflicts. "The Search for Life in the Universe" explores astral life from the frontiers of astrobiology. And "Hollywood Nights" assails the movie industry's feeble efforts to get its night skies right. Known for his ability to blend content, accessibility, and humor, Tyson is a natural teacher who simplifies some of the most complex concepts in astrophysics while simultaneously sharing his infectious excitement about our universe.

    It defines our experience of the world; it echoes through our every waking hour. Time is the very foundation of conscious experience. Yet as familiar as it is, time is also deeply mysterious. We cannot see, hear, smell, taste, or touch it. Yet we do "feel" it--or at least we "think" we feel it. No wonder poets, writers, philosophers, and scientists have grappled with time for centuries.In his latest book, award-winning science writer Dan Falk chronicles the story of how humans have come to understand time over the millennia, and by drawing from the latest research in physics, psychology, and other fields, Falk shows how that understanding continues to evolve. "In Search of Time" begins with our earliest ancestors' perception of time and the discoveries that led--with much effort--to the Gregorian calendar, atomic clocks, and "leap seconds." Falk examines the workings of memory, the brain's remarkable "bridge across time," and asks whether humans are unique in their ability to recall the past and imagine the future. He explores the possibility of time travel, and the paradoxes it seems to entail. Falk looks at the quest to comprehend the beginning of time and how time--and the universe--may end. Finally, he examines the puzzle of time's "flow," and the remarkable possibility that the passage of time may be an illusion.Entertaining, illuminating, and ultimately thought provoking, "In Search of Time "reveals what some of our most insightful thinkers have had to say about time, from Aristotle to Kant, from Newton to Einstein, and continuing with the brightest minds of today.

    The only rock we eat, salt has shaped civilization from the very beginning, and its story is a glittering, often surprising part of the history of humankind. A substance so valuable it served as currency, salt has influenced the establishment of trade routes and cities, provoked and financed wars, secured empires, and inspired revolutions.

    In this sensational and macabre story, we meet the surgeon who counted not only luminaries Benjamin Franklin, Lord Byron, Adam Smith, and Thomas Gainsborough among his patients but also “resurrection men” among his close acquaintances. A captivating portrait of his ruthless devotion to uncovering the secrets of the human body, and the extraordinary lengths to which he went to do so—including body snatching, performing pioneering medical experiments, and infecting himself with venereal disease—this rich historical narrative at last acknowledges this fascinating man and the debt we owe him today.

    We find animals and plants where we do because, over time, the continents have moved, separating and uniting in a long, slow dance; because sea levels have risen, cutting off one bit of land from another; because new and barren volcanic islands have risen up from the sea; and because animals and plants vary greatly in their ability to travel, and separation causes the formation of new species. This is the story of how life has responded to, and has in turn altered, the ever-changing Earth. And it includes many fascinating tales--of pygmy mammoths and elephant birds and of radical ideas by bold young scientists.

    Once one of the continent’s most ubiquitous mammals, they ranged from the Atlantic to the Pacific, and from the Rio Grande to the edge of the northern tundra. Wherever there was wood and water, there were beavers — 60 million (or more) — and wherever there were beavers, there were intricate natural communities that depended on their activities. Then the European fur traders arrived.In Once They Were Hats, Frances Backhouse examines humanity’s 15,000-year relationship with Castor canadensis, and the beaver’s even older relationship with North American landscapes and ecosystems. From the waterlogged environs of the Beaver Capital of Canada to the wilderness cabin that controversial conservationist Grey Owl shared with pet beavers, Backhouse goes on a journey of discovery to find out what happened after we nearly wiped this essential animal off the map, and how we can learn to live with beavers now that they’re returning.

    These centuries gave birth to the basic concepts from which modern physics has evolved. In this first volume of his celebrated UNDERSTANDING PHYSICS, Isaac Asimov deals with this fascinating, momentous stage of scientific development with an authority and clarity that add further lustre to an eminent reputation. Demanding the minimum of specialized knowledge from his audience, he has produced a work that is the perfect supplement to the student’s formal textbook, as well as offering invaluable illumination to the general reader.

    Niels Bohr's dictum bears witness to the bewildering impact of quantum theory, flying in the face of classical physics and dramatically transforming scientists' outlook on our relationship with the material world. In this book Paul Davies interviews eight physicists involved in debating and testing the theory, with radically different views of its significance.

    Frizzle were a physics student of Stephen Hawking, she might have written THE UNIVERSE IN YOUR HAND, a wild tour through the reaches of time and space, from the interior of a proton to the Big Bang to the rough suburbs of a black hole. It's friendly, excitable, erudite, and cosmic."—Jordan Ellenberg, New York Times besteselling author of How Not To Be WrongQuantum physics, black holes, string theory, the Big Bang, dark matter, dark energy, parallel universes: even if we are interested in these fundamental concepts of our world, their language is the language of math. Which means that despite our best intentions of finally grasping, say, Einstein's Theory of General Relativity, most of us are quickly brought up short by a snarl of nasty equations or an incomprehensible graph.Christophe Galfard's mission in life is to spread modern scientific ideas to the general public in entertaining ways. Using his considerable skills as a brilliant theoretical physicist and successful young adult author, The Universe in Your Hand employs the immediacy of simple, direct language to show us, not explain to us, the theories that underpin everything we know about our universe. To understand what happens to a dying star, we are asked to picture ourselves floating in space in front of it. To get acquainted with the quantum world, we are shrunk to the size of an atom and then taken on a journey. Employing everyday similes and metaphors, addressing the reader directly, and writing stories rather than equations renders these astoundingly complex ideas in an immediate and visceral way.Utterly captivating and entirely unique, The Universe in Your Hand will find its place among other classics in the field.

    With the help of a beguiling mix of illustrated optical illusions and puzzles, anecdotes, mathematics, and philosophy, Ings reveals age-old mysteries from how humans perceive color to Woody Allen's ability to raise the inner corners of his eyebrows." A Natural History of Seeing delves into both the evolution of sight and the evolution of our understanding of sight. It gives us the natural science - the physics of light and the biology of animals and humans alike - while also addressing Leonardo da Vinci's theories of perception in painting and Homer's confused and strangely limited sense of color. Panoramic in every sense, it reaches back to the first seers (and to ancient beliefs that vision is the product of mysterious optic rays) and forward to the promise of modern experiments in making robots that see.
