In this collection of landmark mathematical works, editor Stephen Hawking has assembled the greatest feats humans have ever accomplished using just numbers and their brains.

    For some of us, the word conjures up memories of ten-pound textbooks and visions of tedious abstract equations. And yet, in reality, calculus is fun, accessible, and surrounds us everywhere we go. In Everyday Calculus, Oscar Fernandez shows us how to see the math in our coffee, on the highway, and even in the night sky.Fernandez uses our everyday experiences to skillfully reveal the hidden calculus behind a typical day's events. He guides us through how math naturally emerges from simple observations-how hot coffee cools down, for example-and in discussions of over fifty familiar events and activities. Fernandez demonstrates that calculus can be used to explore practically any aspect of our lives, including the most effective number of hours to sleep and the fastest route to get to work. He also shows that calculus can be both useful-determining which seat at the theater leads to the best viewing experience, for instance-and fascinating-exploring topics such as time travel and the age of the universe. Throughout, Fernandez presents straightforward concepts, and no prior mathematical knowledge is required. For advanced math fans, the mathematical derivations are included in the appendixes.Whether you're new to mathematics or already a curious math enthusiast, Everyday Calculus invites you to spend a day discovering the calculus all around you. The book will convince even die-hard skeptics to view this area of math in a whole new way.

    The work is predicated on the idea that studying mathematics can generate the same enthusiasm as playing a team sport - without necessarily being competitive.

    

    Each chapter includes many illustrative examples to assist the reader. The book emphasizes methods for finding solutions to differential equations. It provides many abundant exercises, applications, and solved examples with careful attention given to readability. Elementary Differential Equations includes a thorough treatment of power series techniques. In addition, the book presents a classical treatment of several physical problems to show how Fourier series become involved in the solution of those problems. The eighth edition of Elementary Differential Equations has been revised to include a new supplement in many chapters that provides suggestions and exercises for using a computer to assist in the understanding of the material in the chapter. It also now provides an introduction to the phase plane and to different types of phase portraits. A valuable reference book for readers interested in exploring the technological and other applications of differential equations.

    Admittedly real life wasn’t like that. But only, they argued, because we didn’t have enough data to be certain.Then the cracks began to appear. It proved impossible to predict exactly how three planets orbiting each other would move. Meteorologists discovered that the weather was truly chaotic – so dependent on small variations that it could never be predicted for more than a few days out. And the final nail in the coffin was quantum theory, showing that everything in the universe has probability at its heart.That gives human beings a problem. We understand the world through patterns. Randomness and probability will always be alien to us. But it’s time to plunge into this fascinating, shadowy world, because randomness crops up everywhere. Probability and statistics are the only way to get a grip on nature’s workings. They may even seal the fate of free will and predict how the universe will end.Forget Newton’s clockwork universe. Welcome to Dice World.

    Since the late 19th century, the Foster family had been hand-making running shoes, supplying the likes of Eric Liddell and Harold Abrahams - later immortalised in the film Chariots of Fire - as well as providing boots to most Football League clubs. But a family feud between Foster's father and uncle about the direction of their business led to Joe and his brother Jeff setting up a new company, inspired by the success of Adidas and Puma, and so Reebok was born. At first, money was so short that Joe and his wife had to live in their rundown factory, while the machinery that made the shoes was placed around the edge of the floor, because it was so weak it could have collapsed if they'd been positioned in the middle. But, from this inauspicious start, a major new player in the sports equipment field began to emerge, inspired by Joe's marketing vision. By the 1980s, Reebok had become a global phenomenon, when they were the first to latch onto the potential of the aerobics craze inspired by Jane Fonda. Soon, Reeboks were being seen on Hollywood red carpets and even in the film Aliens , where Sigourney Weaver wore a pair of Reebok Alien Stompers.  Like the international bestseller Shoe Dog, by Nike's Phil Knight, Shoemaker is a powerful tale of triumph against all the odds, revealing the challenges and sacrifices that go into creating a world-beating brand; it is also the story of how a small local business can transform itself, with the right products and the right vision, into something much, much bigger.

    He argues that these turning points in the country’s history were not the result of foresight or careful planning but were rather the accidental consequences of major crises that had to be resolved at any cost.

    Here, complete with detailed illustrations and basic as well as advanced solving techniques, is the ultimate speedcuber’s guide. It not only gives the solution to the familiar 3x3x3 cube (which has 43,252,003,274,489,856,000—that’s 43 quintillion—possible positions), but also the 2x2x2, 4x4x4, and staggeringly difficult 5x5x5 puzzles. With millions of cubes out there and countless would-be champions looking for tips to improve their times, this is the definitive manual for this unique sport.

    (The also-rans that year included Tom Wolfe, Verlyn Klinkenborg, and Oliver Sacks.) Hayes's work in this genre has also appeared in such anthologies as The Best American Magazine Writing, The Best American Science and Nature Writing, and The Norton Reader. Here he offers us a selection of his most memorable and accessible pieces--including "Clock of Ages"--embellishing them with an overall, scene-setting preface, reconfigured illustrations, and a refreshingly self-critical "Afterthoughts" section appended to each essay.

    World History

    The year 2000 is alternatively the year 2544 (Buddhist), 6236 (Ancient Egyptian), 5761 (Jewish) or simply the Year of the Dragon (Chinese). The story of the creation of the Western calendar, which is related in this book, is a story of emperors and popes, mathematicians and monks, and the growth of scientific calculation to the point where, bizarrely, our measurement of time by atomic pulses is now more accurate than time itself: the Earth is an elderly lady and slightly eccentric - she loses half a second a century. Days have been invented (Julius Caesar needed an extra 80 days in 46BC), lost (Pope Gregory XIII ditched ten days in 1582) and moved (because Julius Caesar had 31 in his month, Augustus determined that he should have the same, so he pinched one from February).

     Free History BONUS Inside! When the first settlers reached the United States of America and started to chip out a living in the wilderness that seemed so fierce and unfamiliar to their European eyes, they could never have dreamed that someday the land upon which they stood would become one of the most powerful countries in the entire world. When Native Americans first witnessed those white sails bringing ships with white sailors into their world for the first time, they could never have dreamed that within a few centuries their population would be all but destroyed, that they would have to endure massacre after massacre, be stripped of their freedom and confined to comparatively tiny reservations, and walk the Trail of Tears within the next few hundred years. When the preachers of the Great Awakening stood on the backs of wagons or bits of old tree stumps and told the American people a new story of individual freedom and the power of ordinary people, they could never have dreamed that their preaching would trigger a landslide of abolitionism that would end in a civil war that almost tore the entire country apart. When the Civil War was finally won by the Union, and all African Americans' chains were broken at last, the military leaders could never have dreamed that within the next half century, the United States would emerge as one of the world's greatest military powers during the Spanish-American War. And when those soldiers won the struggle against Spain in Cuba, they could never have dreamed that later in the century, Cuba itself would turn against them and become the single greatest threat of nuclear annihilation during the Cold War. When the Wright Brothers first took to the air and Thomas Edison made the lightbulb, they could never have dreamed that American innovation would produce not only the Ford car, basketball, the telephone, and Facebook, but it would also be instrumental in creating the atomic bombs that killed hundreds of thousands of people and finally brought an end to the Second World War. As for Martin Luther King, Jr., he did dream. He had a dream of equality and brotherhood, and his dream at least partially came true in 2008 when America saw the inauguration of its first black president. Never could the slaves of the great plantations of the South have dreamed that that day would ever come, but it did. Nobody could have dreamed it, but it all came to pass, and it became the history of the United States of America. And this is how it all happened...
