String theory has been called the "theory of everything." It seeks to describe all the fundamental forces of nature. It encompasses gravity and quantum mechanics in one unifying theory. But it is unproven and fraught with controversy. After reading this book, you'll be able to draw your own conclusions about string theory.Steve Gubser begins by explaining Einstein's famous equation "E = mc2," quantum mechanics, and black holes. He then gives readers a crash course in string theory and the core ideas behind it. In plain English and with a minimum of mathematics, Gubser covers strings, branes, string dualities, extra dimensions, curved spacetime, quantum fluctuations, symmetry, and supersymmetry. He describes efforts to link string theory to experimental physics and uses analogies that nonscientists can understand. How does Chopin's Fantasie-Impromptu relate to quantum mechanics? What would it be like to fall into a black hole? Why is dancing a waltz similar to contemplating a string duality? Find out in the pages of this book."The Little Book of String Theory" is the essential, most up-to-date beginner's guide to this elegant, multidimensional field of physics.

    The author explodes the old orthodoxies and gives us a convincing picture of how dinosaurs hunted, fed, mated, fought and died.Containing over 200 detailed illustrations, The Great Dinosaur Debate will enthrall "dinosaurmaniacs". It is a bold new look at the extraordinary reign and eventual extinction of the awesome behemoths who ruled the earth for 150 million years.

    With this astonishing collection of tree portraits, Thomas Pakenham produced a new kind of tree book. The arrangement owed little to conventional botany. The sixty trees were grouped according to their own strong personalities: Natives, Travellers, Shrines, Fantasies and Survivors. From the ancient native trees, many of which are huge and immeasurably old, to the exotic newcomers from Europe, the East and North America, MEETINGS WITH REMARKABLE TREES captures the history and beauty of these entrancing living structures. Common to all these trees is their power to inspire awe and wonder. This is a lovingly researched book, beautifully illustrated with colour photographs, engravings and maps - a moving testimonial to the Earth's largest and oldest living structures.

    From Edward Lorenz’s discovery of the Butterfly Effect, to Mitchell Feigenbaum’s calculation of a universal constant, to Benoit Mandelbrot’s concept of fractals, which created a new geometry of nature, Gleick’s engaging narrative focuses on the key figures whose genius converged to chart an innovative direction for science. In Chaos, Gleick makes the story of chaos theory not only fascinating but also accessible to beginners, and opens our eyes to a surprising new view of the universe.

    In Life's Matrix, Philip Ball writes of water's origins, history, and unique physical character. As a geological agent, water shapes mountains, canyons, and coastlines, and when unleashed in hurricanes and floods its destructive power is awesome. Ball's provocative exploration of water on other planets highlights the possibilities of life beyond Earth. Life's Matrix also examines the grim realities of depletion of natural resources and its effects on the availability of water in the twenty-first century.

    If these galaxies had always been travelling, he reasoned, then they must, at some point, have been on top of one another. This discovery transformed the debate about one of the most fundamental questions of human existence - how did the universe begin?Every society has stories about the origin of the cosmos and its inhabitants, but now, with the power to peer into the early universe and deploy the knowledge gleaned from archaeology, geology, evolutionary biology and cosmology, we are closer than ever to understanding where it all came from. In The Origin of (almost) Everything, New Scientist explores the modern origin stories of everything from the Big Bang, meteorites and dark energy, to dinosaurs, civilisation, timekeeping, belly-button fluff and beyond.From how complex life evolved on Earth, to the first written language, to how humans conquered space, The Origin of (almost) Everything offers a unique history of the past, present and future of our universe.span

    Award-winning photographer Annie Griffiths culled the images to reflect the many variations on the universal theme of beauty. Chapters are organized around the aesthetic concepts that create beauty in a photograph: Light, Composition, Moment (Gesture and Emotion), Motion, Palette, and Wonder.Beyond the introduction and brief essays about each featured concept, the text is light. The photographs speak for themselves, enhanced by lyrical quotes from scholars and poets. In the chapter on Light, for example, we read these words of whimsical wisdom from songwriter Leonard Cohen: "Ring the bells that still can ring. Forget your perfect offering. There is a crack in everything. That's how the lights get in." And then the images flow, of light entering scenes via windows, clouds, and spotlights, from above, alongside, and behind, casting radiance upon young ballerinas and weathered men, into groves of autumn trees and island-dotted seas, revealing everything it touches to be beautiful beyond expectation.To illuminate the theme of Wonder, Griffiths chose a wish from Andre Bazin: "If I had influence with the good fairy...I should ask that her gift to each child in the world be a sense of wonder so indestructible that it would last throughout life." This thought is juxtaposed with an exquisite vision in white, a frame filled with the snowy-pure dots and rays of a bird's fan tail. And on it goes, picture after tantalizing picture, alive with wondrous beauty.When she created National Geographic Simply Beautiful Photographs, Annie Griffiths set two goals: to maximize visual delight, and to create a book unique in the world of publishing--one in which many of the photographs could be purchased as prints. She has succeeded on both counts. Many of these stunning images are available for order, and there can be no doubt as to the visual delight. You must open this book for yourself, and take in its radiant beauty.

    If you want to understand the greatest ideas that shaped our current cosmic cartography, read this book.”—Adam G. Riess, Nobel Laureate in Physics, 2011   This book provides a tour of the “greatest hits” of cosmological discoveries—the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is someone at the forefront of the research—an astrophysicist who literally creates maps of invisible matter in the universe. She not only explains for a wide audience the science behind these essential ideas but also provides an understanding of how radical scientific theories gain acceptance.   The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes—these are some of the puzzling cosmological topics of the early twenty-first century. Natarajan discusses why the acceptance of new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. And she affirms that, shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe.

    Matthew Arnold called Emerson’s essays “the most important work done in prose.”   INCLUDES A MODERN LIBRARY READING GROUP GUIDE

    Now, two of the world's most eminent thinkers -- University of London physicists David Bohm, a former protege of Einstein's and one of the world's most respected quantum physicists, and Stanford neurophysiologist Karl Pribram, one of the architects of our modern understanding of the brain -- believe that the universe itself may be a giant hologram, quite literally a kind of image or construct created, at least in part, by the human mind. This remarkable new way of looking at the universe explains not only many of the unsolved puzzles of physics, but also such mysterious occurrences as telepathy, out-of-body and near death experiences, "lucid" dreams, and even religious and mystical experiences such as feelings of cosmic unity and miraculous healings.

    All of them - hikers, hunters, fishermen, campers, and canoeists - are drawn to the woods for some special reason. Yet few of them see the forest as a whole, as the web of life it truly is. Here, from New York Times bestselling author Richard M. Ketchum, is the extraordinary story of forests and the trees that comprise them.
