For real.If you're like most people, geometry is a sterile and dimly remembered exercise you gladly left behind in the dust of ninth grade, along with your braces and active romantic interest in pop singers. If you recall any of it, it's plodding through a series of miniscule steps only to prove some fact about triangles that was obvious to you in the first place. That's not geometry. Okay, it is geometry, but only a tiny part, which has as much to do with geometry in all its flush modern richness as conjugating a verb has to do with a great novel.Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. The word "geometry," from the Greek for "measuring the world." If anything, that's an undersell. Geometry doesn't just measure the world—it explains it. Shape shows us how.

    Volume One covers the head, neck, and upper extremities. Volume 2 covers the trunk and lower extremities. Many of the black-and-white illustrations have been converted to color in this edition, and chapter figures include orientational diagrams to give students much needed structural references.

    Despite its relatively narrow focus, it is chock full of the pearls of clinical wisdom that students and practitioners treasure, and many of these lessons apply to medicine in general. The book was well characterized by a reviewer of an earlier edition for The New England Journal of Medicine: If only one book about surgery could be made available to physicians from all specialties, it should probably be Silen's recent revision of Cope's Early Diagnosis of the Acute Abdomen. Since the book first appeared more than 30 years ago, it has remained the classic treatise on the initial approach to abdominal pain. Because acute, severe abdominal pain is still a common problem whose misdiagnosis can result in quick death, each generation of beginning physicians is faced with the urgency of learning to make a diagnosis in this high anxiety situation and they appreciate the wise, humane, precisely detailed guidance offered by Cope and Silen. For the 21st Edition, Dr. Silen has again updated the text in a respectful but significant way. He has strengthened its emphasis on pitfalls in the interpretation of CT and ultrasound scans, on misadventures caused by over-reliance on blood tests and radiographs, and on careful history-taking to avoid the costs of inappropriate lab tests. He has also reviewed the data from a randomized clinical trial indicating that patients should receive adequate analgesia while awaiting a definitive diagnosis, a dictum that is contrary to traditional teaching

    The microbiota interacts with our bodies in a number of powerful ways; the Sonnenburgs argue that it determines in no small part whether we’re sick or healthy, fit or obese, sunny or moody. The microbiota has always been with us, and in fact has coevolved with humans, entwining its functions with ours so deeply, the Sonnenburgs show us, humans are really composite organisms having both microbial and human parts. But now, they argue, because of changes to diet, antibiotic over-use, and over-sterilization, our gut microbiota is facing a “mass extinction event,” which is causing our bodies to go haywire, and may be behind the mysterious spike in some of our most troubling modern afflictions, from food allergies to autism, cancer to depression. It doesn’t have to be this way.The Good Gut offers a new plan for health that focuses on how to nourish your microbiota, including recipes and a menu plan. In this groundbreaking work, the Sonnenburgs show how we can keep our microbiota off the endangered species list and how we can strengthen the community that inhabits our gut and thereby improve our own health. The answer is unique for each of us, and it changes as you age. In this important and timely investigation, the Sonnenburgs look at safe alternatives to antibiotics; dietary and lifestyle choices to encourage microbial health; the management of the aging microbiota; and the nourishment of your own individual microbiome. Caring for our gut microbes may be the most important health choice we can make.

    Our species emerged out of the depths of time into a world already populated by these great carnivores. Before we mastered iron and later developed firearms, we had few defences against bears--only watchful caution and elaborate ceremonies and sacrifices to ward off fear.Where human populations grow, bears have traditionally dwindled or disappeared. But when we return to the wild, to places where bears still survive, all our primeval fears awaken again. The risk of an automobile accident on the way to bear country far outstrips the risk of a close-range encounter with a bear, but it's the bear that worries us as we hurtle down the pavement at a hundred kilometres an hour.In this timely and sensitive book, Kevin Van Tighem calls on decades of experience, knowledge and understanding in order to enlighten readers about our relationship with and attitude toward bears. Along the way we are confronted with the realities confronting these great animals as a result of our ever-expanding human population and their ever-shrinking natural habitat. Through historical research, field observation, practical advice, personal anecdotes and an array of stunning photos, Van Tighem has written a comprehensive book that is meant to demystify bears in order to promote a deeper understanding of these powerful yet vulnerable creatures.

    Here, for the first time, is the complete history of the quest to understand Earth’s magnetism—from the ancient Greeks’ fascination with lodestone, to the geological discovery that the North Pole has not always been in the North—and to the astonishing modern conclusions that finally revealed the true source.Richly illustrated and skillfully told, North Pole, South Pole unfolds the human story behind the science: that of the inquisitive, persevering, and often dissenting thinkers who unlocked the secrets at our planet’s core.

    In this unconventional introduction, physicist Leonard Susskind and hacker-scientist George Hrabovsky offer a first course in physics and associated math for the ardent amateur. Unlike most popular physics books—which give readers a taste of what physicists know but shy away from equations or math—Susskind and Hrabovsky actually teach the skills you need to do physics, beginning with classical mechanics, yourself. Based on Susskind's enormously popular Stanford University-based (and YouTube-featured) continuing-education course, the authors cover the minimum—the theoretical minimum of the title—that readers need to master to study more advanced topics.An alternative to the conventional go-to-college method, The Theoretical Minimum provides a tool kit for amateur scientists to learn physics at their own pace.

    The authors capture students' interest with up-to-date coverage of cutting edge topics and research. This text will help students connect the science of genetics to the issues of today through interesting and thought-provoking applications. The sixth edition boasts the next generation of media integration including Gen CD-X (student CD-ROM and Companion Website).

    Written in a concise, bulleted outline format, this well-illustrated text offers 500 USMLE-style review questions, answers, and explanations and features comprehensive content and upgraded USMLE Step 1 information.

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    Its full-colour illustration program includes many novel, visually effective features to help students learn.

    This edition contains NEW tables on Properties of Ionic Liquids, Solubilities of Hydrocarbons in Sea Water, Solubility of Organic Compounds in Superheated Water, and Nutritive Value of Foods. It also updates many tables including Critical Constants, Heats of Vaporization, Aqueous Solubility of Organic Compounds, Vapor Pressure of Mercury, Scientific Abbreviations and Symbols, and Bond Dissociation Energies. The 88th Edition also presents a new Foreword written by Dr. Harold Kroto, a 1996 Nobel Laureate in Chemistry.

    How can we catch schools that cheat on standardized tests? How does Netflix know which movies you’ll like? What is causing the rising incidence of autism? As best-selling author Charles Wheelan shows us in Naked Statistics, the right data and a few well-chosen statistical tools can help us answer these questions and more.For those who slept through Stats 101, this book is a lifesaver. Wheelan strips away the arcane and technical details and focuses on the underlying intuition that drives statistical analysis. He clarifies key concepts such as inference, correlation, and regression analysis, reveals how biased or careless parties can manipulate or misrepresent data, and shows us how brilliant and creative researchers are exploiting the valuable data from natural experiments to tackle thorny questions.And in Wheelan’s trademark style, there’s not a dull page in sight. You’ll encounter clever Schlitz Beer marketers leveraging basic probability, an International Sausage Festival illuminating the tenets of the central limit theorem, and a head-scratching choice from the famous game show Let’s Make a Deal—and you’ll come away with insights each time. With the wit, accessibility, and sheer fun that turned Naked Economics into a bestseller, Wheelan defies the odds yet again by bringing another essential, formerly unglamorous discipline to life.

    They'll also find the related analytic geometry much easier. The clear review of algebra and geometry in this edition will make calculus easier for students who wish to strengthen their knowledge in these areas.
