In addition to exploring color healing, this book can be used as a stunning crystal identifier, describing the color, shape, source and rarity of 120 examples. The full spectrum of crystal information is covered, including expert guidance, and insight into the history of crystals, crystal placements, the use of crystals in your life and the importance of crystals to children.

    Who has not wondered about how the human body works? Can a person drink too much water? How does gravity make things fall? From topics as varied as the Earth and atoms to sports and music, we all carry with us those questions we've always wanted answered but never knew whom to ask.Mysteries lurk in our bodies, our houses, the outdoors, in the sky above us, and the universe beyond us. Now, award-winning high school science teacher Larry Scheckel tackles 250 questions that help us to more clearly understand all of these mysteries. Scheckel perfected the art of explaining science topics not only as a science teacher for more than 38 years in his native Wisconsin, but also through writing a weekly column in his local paper, the "Tomah Journal," in which each week he'd field a question like those that are collected in this book.

    The author's enthusiasm for and knowledge of the current theatre, highlighted by contemporary production shots from around the world, put the students in the front row.

    We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    

    Spanning the first century of the Industrial Revolution, this 1868 compilation features simplified, concise illustrations of the mechanisms used in hydraulics, steam engines, pneumatics, presses, horologes, and scores of other machines.The movements of each of the 507 mechanisms are depicted in drawings on the left-hand page, and the facing page presents a brief description of the item's use and operation. Ranging from simple to intricately complex, the mechanisms offer a fascinating view of the variety of small components that constitute complex machinery. A detailed index provides easy reference to specific mechanisms.Inventors, tinkerers, and anyone with an interest in the history of invention and technology will find this volume a treasury of information and inspiration.

    Two introductory chapters detail the authors’ theories about how to work with crystals and stones—including the concept of crystal resonance and the scientific observation that living organisms (such as ourselves) are liquid crystalline structures. An illuminating alphabetical journey through the mineral kingdom, stone by stone, follows.Each entry begins with the stone name and photo, plus its elemental and chakra correspondences, as well as keywords that indicate its properties. Next comes a description of the crystal structure, hardness, history, and known locations of each mineral, plus any relevant legend or lore from the past. Each author then offers an essay on the subtle energy properties and spiritual applications of the stone. The entries conclude with summaries of the spiritual, emotional, and physical healing qualities of the stone, and an affirmation for evoking its potential benefits. The book’s presentation is straightforward enough to make it an excellent introduction for beginners, yet the level of detail and the depth of research make it an invaluable resource for the most experienced stone practitioners.

    In writing the book James Stewart asked himself: What is essential for a three-semester calculus course for scientists and engineers? Stewart's ESSENTIAL CALCULUS offers a concise approach to teaching calculus that focuses on major concepts and supports those concepts with precise definitions, patient explanations, and carefully graded problems. Essential Calculus is only 850 pages-two-thirds the size of Stewart's other calculus texts (CALCULUS, Fifth Edition and CALCULUS, EARLY TRANSCENDENTALS, Fifth Edition)-and yet it contains almost all of the same topics. The author achieved this relative brevity mainly by condensing the exposition and by putting some of the features on the website, www.StewartCalculus.com. Despite the reduced size of the book, there is still a modern flavor: Conceptual understanding and technology are not neglected, though they are not as prominent as in Stewart's other books. ESSENTIAL CALCULUS has been written with the same attention to detail, eye for innovation, and meticulous accuracy that have made Stewart's textbooks the best-selling calculus texts in the world.

    Both the book and film were inspired by a series of multimedia presentations on global warming that Gore created and delivers to groups around the world. With this book, Gore, who is one of our environmental heroes—and a leading expert—brings together leading-edge research from top scientists around the world; photographs, charts, and other illustrations; and personal anecdotes and observations to document the fast pace and wide scope of global warming. He presents, with alarming clarity and conclusiveness—and with humor, too—that 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. This riveting new book—written in an accessible, entertaining style—will open the eyes of even the most skeptical.

    The chapters are organized by test type and each chapter begins with a list of the tests covered within the test type, as well as an overview of that category including specimen collection techniques. The tests are presented in a consistent format that includes normal findings, indications, contraindications, potential complications, interfering factors, procedure and patient care, test results and clinical significance, and related tests. This full-color book is easy to use and covers virtually every clinically significant test, including more than 50 new to this edition.

    She struggles for survival and for self-esteem, embarking on a love affair with the 18-year-old son of her most powerful opponent, brutal and charismatic rancher, Buck Calder.

    In the past, discoveries often had to wait for the rise of the next generation to see questions in a new light and let go of old truisms. Today, in a world that is defined by a rapid rate of change, staying on the cutting edge has as much to do with shedding outdated notions as adopting new ones. In this spirit, John Brockman, publisher of the online salon Edge.org ("the world's smartest website"—The Guardian), asked 175 of the world's most influential scientists, economists, artists, and philosophers: What scientific idea is ready for retirement?Jared Diamond explores the diverse ways that new ideas emerge * Nassim Nicholas Taleb takes down the standard deviation * Richard Thaler and novelist Ian McEwan reveal the usefulness of "bad" ideas * Steven Pinker dismantles the working theory of human behavior * Richard Dawkins renounces essentialism * Sherry Turkle reevaluates our expectations of artificial intelligence * Physicist Andrei Linde suggests that our universe and its laws may not be as unique as we think * Martin Rees explains why scientific understanding is a limitless goal * Alan Guth rethinks the origins of the universe * Sam Harris argues that our definition of science is too narrow * Nobel Prize winner Frank Wilczek disputes the division between mind and matter * Lawrence Krauss challenges the notion that the laws of physics were preordained * plus contributions from Daniel Goleman, Mihaly Csikszentmihalyi, Nicholas Carr, Rebecca Newberger Goldstein, Matt Ridley, Stewart Brand, Sean Carroll, Daniel C. Dennett, Helen Fisher, Douglas Rushkoff, Lee Smolin, Kevin Kelly, Freeman Dyson, and others.

    The name dinosaur was coined in 1842 by an English anatomist Richard Owen, a highly ambitious, machiavellian schemer and villain of Deborah Cadbury's The Dinosaur Hunters: A True Story of Scientific Rivalry and the Discovery of the Prehistoric World. Her hero is Gideon Mantell, a practising doctor, who found and first described many of the bones of the beasts that subsequently became known as dinosaurs. Full of quotes from contemporary sources, The Dinosaur Hunters brilliantly evokes the Dickensian world of early Victorian science and society. From Mary Anning, the self-taught fossil hunter of Lyme Regis to the academic and deeply eccentric Dean Buckland of Oxford University, the story tells of reputations made and lost as self-help, self-promotion, over-wheening pride, folly and social climbing all played their part in the emerging story of the geological past. The dinosaurs, although central to the story, are also a vehicle for the much larger, more interesting and important story about the struggle to understand the meaning of fossils and what they tell us about prehistory. Deborah Cadbury, an award-winning TV science producer and acclaimed author of The Feminisation of Nature has thoroughly researched her topic and steeped herself in the intricacies of the scientific debates of the time. With black and white illustrations, extensive notes, a bibliography and index, the result is one of the best popular science histories. --Douglas Palmer.
