Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives, and the increasing fortunes of nations, hung on a resolution.The scientific establishment of Europe—from Galileo to Sir Issac Newton—had mapped the heavens in both hemispheres in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution—a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is a dramatic human story of an epic scientific quest and Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clock-making, and opens a new window on our world.On its 10th anniversary, a gift edition of this classic book, with a forward by one of history's greatest explorers, and eight pages of color illustrations.

    Comprehensive explanations of their secret rituals and symbolism. Including alchemy, astrology, Kabbalism, ceremonial magic, animal magnetism and more.

    Their work has uncovered a number of the universe’s more surprising secrets, and many believe further wonders remain hidden within the theory’s tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, astrophysicist Pedro Ferreira brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma, fueling a century of intellectual struggle and triumph.. Einstein’s theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics, yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler’s Germany, hounded in Stalin’s Russia, and disdained in 1950s America. Even today, PhD students are warned that specializing in general relativity will make them unemployable. Despite these pitfalls, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein’s theory. We are in the midst of a momentous transformation in modern physics. As scientists look farther and more clearly into space than ever before, The Perfect Theory reveals the greater relevance of general relativity, showing us where it started, where it has led, and where it can still take us.

    This work focuses on the maths skills necessary to pass the GMAT, with nearly 300 questions and explanations on subjects such as arithmetic, algebra, geometry and data sufficiency.

    Even when dealing with standard material, Stillwell manages to dramatize it and to make it worth rethinking. In short, his book is a splendid addition to the genre of works that build royal roads to mathematical culture for the many." (Mathematical Intelligencer)This second edition includes new chapters on Chinese and Indian number theory, on hypercomplex numbers, and on algebraic number theory. Many more exercises have been added, as well as commentary to the exercises explaining how they relate to the preceding section, and how they foreshadow later topics.

    Many today are well on their way to becoming a sad statistic in the war on obesity, high blood sugar, and the related diseases—including diabetes—that can result from a diet that’s seriously out of whack.

Now Dennis offers readers the next step in the battle: 60 practical ways to manage their blood sugar without resorting to a bland unsatisfying diet of turnips and tuna fish. In this step by step, change by change plan, readers will learn how to: reduce their intake of carbs, exercise more effectively, and shed excess weight. A must-have book for readers serious about regaining their health while also lowering their weight and increasing their energy.

    From the first millennium BC until today, the myths have been repeated in an inexhaustible series of variations and reinterpretations. They can be found in the latest movies and television shows and in software for interactive computer games. This book combines a retelling of Greek myths with a comprehensive account of the world in which they developed their themes, their relevance to Greek religion and society, and their relationship to the landscape."Contexts, Sources, Meanings" describes the main literary and artistic sources for Greek myths, and their contexts, such as ritual and theater."Myths of Origin" includes stories about the beginning of the cosmos, the origins of the gods, the first humans, and the founding of communities."The Olympians: Power, Honor, Sexuality" examines the activities of all the main divinities."Heroic exploits" concentrates on the adventures of Perseus, Jason, Herakles, and other heroes."Family sagas" explores the dramas and catastrophes that befall heroes and heroines."A Landscape of Myths" sets the stories within the context of the mountains, caves, seas, and rivers of Greece, Crete, Troy, and the Underworld."Greek Myths after the Greeks" describes the rich tradition of retelling, from the Romans, through the Renaissance, to the twenty-first century.Complemented by lavish illustrations, genealogical tables, box features, and specially commissioned drawings, this will be an essential book for anyone interested in these classic tales and in the world of the ancient Greeks.

    November 2015 is the 100th anniversary of Einstein’s discovery of the General Theory of Relativity.Levenson, head of MIT’s Science Writing Program, tells the captivating, unusual, and nearly-forgotten backstory behind Einstein’s invention of the Theory of Relativity, which completely changed the course of science forever. For over 50 years before Einstein developed his theory, the world’s top astronomers spent countless hours and energy searching for a planet, which came to be named Vulcan, that had to exist, it was thought, given Isaac Newton’s theories of gravity. Indeed, in the two centuries since Newton’s death, his theory had essentially become accepted as fact. It took Einstein’s genius to realize the mystery of the missing planet wasn’t a problem of measurements or math but of Newton’s theory of gravity itself. Einstein’s Theory of Relativity proved that Vulcan did not and could not exist, and that the decades-long search for it had merely been a quirk of operating under the wrong set of assumptions about the universe. Thomas Levenson tells this unique story, one of the strangest episodes in the history of science, with elegant simplicity, fast-paced drama, and lively characters sure to capture the attention of a wide group of readers.

    Quantum-Touch differs from other healing techniques because it does not require long years of study and presents none of the common hurdles of understanding or application; anyone can learn to use it to become a healer, both of others and of self. In this new edition of his best-selling guide, Richard Gordon leads the reader step by step, clearly explaining how to use breathing and body-focusing techniques to raise one's energy levels. Once that is achieved, the healer can correct posture and alignment, reduce pain and inflammation, help balance emotional distress, and even heal pets. Above all, Quantum-Touch can be used in tandem with all other healing modalities, including Western medicine, and its efficacy has been attested to by physicians, acupuncturists, chiropractors, and other healing professionals.

    Newly revised, this edition of the handbook includes more than 50 new monographs with a list of synonyms at the end of each monograph, a revised insulin monograph, an expanded ophthalmology section and new headings for reproductive/nursing safety.

    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.
