From the sudden expansion of a cloud of gas to the cooling of hot metal--everything is moved or restrained by four simple laws. Written by Peter Atkins, one of the world's leading authorities on thermodynamics, this powerful and compact introduction explains what these four laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader a step at a time, Atkins begins with Zeroth (so named because the first two laws were well established before scientists realized that a third law, relating to temperature, should precede them--hence the jocular name zeroth), and proceeds through the First, Second, and Third Laws, offering a clear account of concepts such as the availability of work and the conservation of energy. Atkins ranges from the fascinating theory of entropy (revealing how its unstoppable rise constitutes the engine of the universe), through the concept of free energy, and to the brink, and then beyond the brink, of absolute zero. About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam.

    Maudlin explains special relativity using a geometrical approach, emphasizing intrinsic space-time structure rather than coordinate systems or reference frames. He gives readers enough detail about special relativity to solve concrete physical problems while presenting general relativity in a more qualitative way, with an informative discussion of the geometrization of gravity, the bending of light, and black holes. Additional topics include the Twins Paradox, the physical aspects of the Lorentz-FitzGerald contraction, the constancy of the speed of light, time travel, the direction of time, and more.Introduces nonphysicists to the philosophical foundations of space-time theoryProvides a broad historical overview, from Aristotle to EinsteinExplains special relativity geometrically, emphasizing the intrinsic structure of space-timeCovers the Twins Paradox, Galilean relativity, time travel, and moreRequires only basic algebra and no formal knowledge of physicsTim Maudlin is professor of philosophy at New York University.

    Stengers and Prigogine show how the two great themes of classic science, order and chaos, which coexisted uneasily for centuries, are being reconciled in a new and unexpected synthesis.

    This text has invited more than 4 million students into the study of this dynamic and essential discipline.The authors have restructured each chapter around a conceptual framework of five or six big ideas. An Overview draws students in and sets the stage for the rest of the chapter, each numbered Concept Head announces the beginning of a new concept, and Concept Check questions at the end of each chapter encourage students to assess their mastery of a given concept. New Inquiry Figures focus students on the experimental process, and new Research Method Figures illustrate important techniques in biology. Each chapter ends with a Scientific Inquiry Question that asks students to apply scientific investigation skills to the content of the chapter.

    Almost five hundred years later, the revolution he set in motion is nearly complete. Just as earth is not the center of things, the life on it, it appears, is not unique to the planet. Or is it? The Life of Super-Earths is a breathtaking tour of current efforts to answer the age-old question: Are we alone in the universe? Astronomer Dimitar Sasselov, the founding director of Harvard University’s Origins of Life Initiative, takes us on a fast-paced hunt for habitable planets and alien life forms. He shows how the search for “super-Earths”—rocky planets like our own that orbit other stars—may provide the key to answering essential questions about the origins of life here and elsewhere. That is, if we don’t find the answers to those questions here first. As Sasselov and other astronomers have uncovered planets with mixes of elements different from our own, chemists have begun working out the heretofore unseen biochemistries that those planets could support. That knowledge is feeding directly into synthetic biology—the effort to build wholly novel forms of life—making it likely that we will first discover truly “alien” life forms in an earthly lab, rather than on a remote planet thousands of light years away. Sasselov tells the gripping story of a moment of unprecedented potential—a convergence of pioneering efforts in astronomy and biology to peer into the unknown. The Life of Super-Earths offers nothing short of a transformation in our understanding of life and its place in the cosmos.

    Using the dialogue form, a genre common in classical philosophical works, Galileo masterfully demonstrates the truth of the Copernican system over the Ptolemaic one, proving, for the first time, that the earth revolves around the sun. Its influence is incalculable. The Dialogue is not only one of the most important scientific treatises ever written, but a work of supreme clarity and accessibility, remaining as readable now as when it was first published. This edition uses the definitive text established by the University of California Press, in Stillman Drake’s translation, and includes a Foreword by Albert Einstein and a new Introduction by J. L. Heilbron.

    This work has played a major role in the development of our current understanding of the profound nature of quantum concepts and of the fundamental limitations they impose on the applicability of the classical ideas of space, time and locality. This book contains all of John Bell's published and unpublished papers on the conceptual and philosophical problems of quantum mechanics.

    After sampling myths explaining First Light, the story moves on to early philosophers' queries, then through the centuries, from Buddhist temples to Biblical scripture, when light was the soul of the divine.Battling darkness and despair, Gothic architects crafted radiant cathedrals while Dante dreamed a "heaven of pure light." Later, following Leonardo's advice, Renaissance artists learned to capture light on canvas. During the Scientific Revolution, Galileo gathered light in his telescope, Descartes measured the rainbow, and Newton used prisms to solidify the science of optics. But even after Newton, light was an enigma. Particle or wave? Did it flow through an invisible "ether"? Through the age of Edison and into the age of lasers, Light reveals how light sparked new wonders--relativity, quantum electrodynamics, fiber optics, and more.Although lasers now perform everyday miracles, light retains its eternal allure. "For the rest of my life," Einstein said, "I will reflect on what light is." Light explores and celebrates such curiosity.

    It also explores more advanced topics, such as normal modes, the Lagrangian method, gyroscopic motion, fictitious forces, 4-vectors, and general relativity. It contains more than 250 problems with detailed solutions so students can easily check their understanding of the topic. There are also over 350 unworked exercises which are ideal for homework assignments. Password protected solutions are available to instructors at www.cambridge.org/9780521876223. The vast number of problems alone makes it an ideal supplementary text for all levels of undergraduate physics courses in classical mechanics. Remarks are scattered throughout the text, discussing issues that are often glossed over in other textbooks, and it is thoroughly illustrated with more than 600 figures to help demonstrate key concepts.

    When the boy's eyes were healed they removed the bandages and, waving a hand in front of the child's physically perfect eyes, asked him what he saw. "I don't know," was his only reply. What he saw was only a varying brightness in front of him. However, when allowed to touch the hand as it began to move, he cried out in a voice of triumph, "It's moving!" He could feel it move, but he still needed laboriously to learn to see it move. Light and eyes were not enough to grant him sight. How, then, do we see? What's the difference between seeing and perception? What is light?From ancient times to the present, from philosophers to quantum physicists, nothing has so perplexed, so fascinated, so captivated the mind as the elusive definition of light. In Catching the Light, Arthur Zajonc takes us on an epic journey into history, tracing how humans have endeavored to understand the phenomenon of light. Blending mythology, religion, science, literature, and painting, Zajonc reveals in poetic detail the human struggle to identify the vital connection between the outer light of nature and the inner light of the human spirit. He explains the curiousness of the Greeks' blue and green "color blindness": Odysseus gazing longingly at the "wine-dark sea"; the use of chloros (green) as the color of honey in Homer's Odessey; and Euripides' use of the color green to describe the hue of tears and blood. He demonstrates the complexity of perception through the work of Paul Cézanne--the artist standing on the bank of a river, painting the same scene over and over again, the motifs multiplying before his eyes. And Zajonc goes on to show how our quest for an understanding of light, as well as the conclusions we draw, reveals as much about the nature of our own psyche as it does about the nature of light itself. For the ancient Egyptians the nature of light was clear--it simply was the gaze of God. In the hands of the ancient Greeks, light had become the luminous inner fire whose ethereal effluence brought sight. In our contemporary world of modern quantum physics, science plays the greatest part in our theories of light's origin--from scientific perspectives such as Sir Isaac Newton's "corpuscular theory of light" and Michael Faraday's "lines of force" to such revolutionary ideas as Max Planck's "discrete motion of a pendulum" (the basis of quantum mechanics), Albert Einstein's "particles of light" and "theory of relativity," and Niels Bohr's "quantum jumps." Yet the metaphysical aspects of the scientific search, Zajonc shows, still loom large. For the physicist Richard Feynman, a quantum particle travels all paths, eventually distilling to one path whose action is least--the most beautiful path of all. Whatever light is, here is where we will find it.With rare clarity and unmatched lyricism, Zajonc illuminates the profound implications of the relationships between the multifaceted strands of human experience and scientific endeavor. A fascinating search into our deepest scientific mystery, Catching the Light is a brilliant synthesis

    Chance and Necessity is a philosophical statement whose intention is to sweep away as both false and dangerous the animist conception of man that has dominated virtually all Western worldviews from primitive cultures to those of dialectical materialists. He bases his argument on the evidence of modern biology, which indisputably shows, that man is the product of chance genetic mutation. With the unrelenting logic of the scientist, he draws upon what we now know (and can theorize) of genetic structure to suggest an new way of looking at ourselves. He argues that objective scientific knowledge, the only reliable knowledge, denies the concepts of destiny or evolutionary purpose that underlie traditional philosophies. He contends that the persistence of those concepts is responsible for the intensifying schizophrenia of a world that accepts, and lives by, the fruits of science while refusing to face its moral implications. Dismissing as "animist" not only Plato, Hegel, Bergson and Teilhard de Chardin but Spencer and Marx as well, he calls for a new ethic that will recognize the distinction between objective knowledge and the realm of values--an ethic of knowledge that can, perhaps, save us from our deepening spiritual malaise, from the new age of darkness he sees coming.PrefaceOf strange objects Vitalisms and animisms Maxwell's demons Microscopic cyberneticsMolecular ontogenesis Invariance and perturbationsEvolution The frontiers The kingdom and the darknessAppendixes

    Recent discoveries in the new field of vacuum physics now show that this Akashic field is real and has its equivalent in the zero-point field that underlies space itself. This field consists of a subtle sea of fluctuating energies from which all things arise: atoms and galaxies, stars and planets, living beings, and even consciousness. This zero-point Akashic-field--or “A-field”-- is not only the original source of all things that arise in time and space; it is also the constant and enduring memory of the universe. It holds the record of all that ever happened in life, on Earth, and in the cosmos and relates it to all that is yet to happen.Scientist and philosopher Ervin Laszlo conveys the essential element of this vision of the “informed universe” in language that is accessible and clear. The informed universe lends credence to our deepest intuitions of the oneness of life and the whole of creation. We discover that, as philosopher William James stated, “we are like islands in the sea, separate on the surface but connected in the deep.”
