But the wonderful development, however, in a few months, of a large, heterogeneous collection of men into a solid, keen, self-sacrificing unit, was but another instance of the way in which war improves the character and temperament of man. It was entirely new for men who were formerly in a regiment, full of traditions, to find themselves in the[...].

    S. dollar bill? Did a pharaoh inspire Moses to worship one God? What’s a Canaanite demoness doing at a rock concert?Since the beginning of time, people have been insatiably curious. They’ve asked questions about where we come from, why the stars shine and the seasons change, and what constitutes evil. The imaginative answers crafted by our ancestors have served as religion, science, philosophy, and popular literature. In this latest installment of the New York Times bestselling Don’t Know Much About® series, Kenneth C. Davis introduces and explains the great myths of the world using his engaging and delightfully irreverent question-and-answer style. He tackles the epic of Gilgamesh; Achilles and the Trojan War; Stonehenge and the Druids; Odin, Thor, and the entire Norse pantheon; Native American myths, and much more, including the dramatic life and times of the man who would be Buddha. From Mount Olympus to Machu Picchu, here is an insightful, lively look at the greatest stories ever told.

    It now has 600,000 to a million page hits daily. Every now and then, Munroe would get emails asking him to arbitrate a science debate. 'My friend and I were arguing about what would happen if a bullet got struck by lightning, and we agreed that you should resolve it . . . ' He liked these questions so much that he started up What If. If your cells suddenly lost the power to divide, how long would you survive? How dangerous is it, really, to be in a swimming pool in a thunderstorm? If we hooked turbines to people exercising in gyms, how much power could we produce? What if everyone only had one soulmate?When (if ever) did the sun go down on the British empire? How fast can you hit a speed bump while driving and live?What would happen if the moon went away?In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators. His responses are masterpieces of clarity and hilarity, studded with memorable cartoons and infographics. They often predict the complete annihilation of humankind, or at least a really big explosion. Far more than a book for geeks, WHAT IF: Serious Scientific Answers to Absurd Hypothetical Questions explains the laws of science in operation in a way that every intelligent reader will enjoy and feel much the smarter for having read.

    Ignored by his mother, scorned by contemporaries, seemingly at war with the world in which he lived, Newton turned his energies to things unseen. His laws of motion and law of universal gravitation would set the stage for a most extraordinary life. Inside you will read about... ✓ The English Civil War ✓ Newton and the Apple ✓ Newton's Work in Mathematics & Optics ✓ Middle Years in Scientific Experiments ✓ Principia ✓ Newton and Alchemy ✓ Later Life and Death And much more! Follow along as you travel from a rugged stone farmhouse to Trinity College, Cambridge to the halls of London exhibitions where Newton found himself the celebrity of the age. Looking back on Aristotle, and inspired by all that Galileo had brought the world, Newton made his life work much of what is heralded as the modern age. He saw what no one else did, and his vision saw into the universe. See how he did it, and why.

    His quick mastery of quantum mechanics earned him a place at Los Alamos working on the Manhattan Project under J. Robert Oppenheimer, where the giddy young man held his own among the nation’s greatest minds. There, Feynman turned theory into practice, culminating in the Trinity test, on July 16, 1945, when the Atomic Age was born. He was only twenty-seven. And he was just getting started. In this sweeping biography, James Gleick captures the forceful personality of a great man, integrating Feynman’s work and life in a way that is accessible to laymen and fascinating for the scientists who follow in his footsteps.

    

    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.

    Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space: a multiverse in which you have an infinite number of doppelgängers, each reading this sentence in a distant universe; a multiverse comprising a vast ocean of bubble universes, of which ours is but one; a multiverse that endlessly cycles through time, or one that might be hovering millimeters away yet remains invisible; another in which every possibility allowed by quantum physics is brought to life. Or, perhaps strangest of all, a multiverse made purely of math.Greene, one of our foremost physicists and science writers, takes us on a captivating exploration of these parallel worlds and reveals how much of reality’s true nature may be deeply hidden within them. And, with his unrivaled ability to make the most challenging of material accessible and entertaining, Greene tackles the core question: How can fundamental science progress if great swaths of reality lie beyond our reach?Sparked by Greene’s trademark wit and precision, The Hidden Reality is at once a far-reaching survey of cutting-edge physics and a remarkable journey to the very edge of reality—a journey grounded firmly in science and limited only by our imagination.

    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.
