The adjective 'medieval' has become a synonym for brutality and uncivilized behavior. Yet without the work of medieval scholars there could have been no Galileo, no Newton and no Scientific Revolution. In God's Philosophers, James Hannam debunks many of the myths about the Middle Ages, showing that medieval people did not think the earth is flat, nor did Columbus 'prove' that it is a sphere; the Inquisition burnt nobody for their science nor was Copernicus afraid of persecution; no Pope tried to ban human dissection or the number zero. God's Philosophers is a celebration of the forgotten scientific achievements of the Middle Ages - advances which were often made thanks to, rather than in spite of, the influence of Christianity and Islam. Decisive progress was also made in technology: spectacles and the mechanical clock, for instance, were both invented in thirteenth-century Europe. Charting an epic journey through six centuries of history, God's Philosophers brings back to light the discoveries of neglected geniuses like John Buridan, Nicole Oresme and Thomas Bradwardine, as well as putting into context the contributions of more familiar figures like Roger Bacon, William of Ockham and Saint Thomas Aquinas.

    It was a harrowing test of endurance on a snowbound cordillera that ended in a miraculous rescue. Now comes the unflinching and emotional true story by one of the men who found his way home.Four decades after the tragedy, a climber discovered survivor Eduardo Strauch’s wallet near the memorialized crash site and returned it to him. It was a gesture that compelled Strauch to finally “break the silence of the mountains.”In this revelatory and rewarding memoir, Strauch withholds nothing as he reveals the truth behind the life-changing events that challenged him physically and tested him spiritually, but would never destroy him. In revisiting the horror story we thought we knew, Strauch shares the lessons gleaned from far outside the realm of rational learning: how surviving on the mountain, in the face of its fierce, unforgiving power and desolate beauty, forever altered his perception of love, friendship, death, fear, loss, and hope.

    Within that story is the incredible tale of the human conflict between Robert Oppenheimer, Ernest Lawrence, and Edward Teller-the scientists most responsible for the advent of weapons of mass destruction.How did science-and its practitioners-enlisted in the service of the state during the Second World War, become a slave to its patron during the Cold War? The story of these three men, builders of the bombs, is fundamentally about loyalty-to country, to science, and to each other-and about the wrenching choices that had to be made when these allegiances came into conflict.Gregg Herken gives us the behind-the-scenes account based upon a decade of research, interviews, and newly released Freedom of Information Act and Russian documents. Brotherhood of the Bomb is a vital slice of American history told authoritatively-and grippingly-for the first time.

    It has built on itself for centuries, becoming vast and increasingly specialized. Most of us are ignorant about the fundamental principles of the civilization that supports us, happily utilizing the latest—or even the most basic—technology without having the slightest idea of why it works or how it came to be. If you had to go back to absolute basics, like some sort of postcataclysmic Robinson Crusoe, would you know how to re-create an internal combustion engine, put together a microscope, get metals out of rock, accurately tell time, weave fibers into clothing, or even how to produce food for yourself? Regarded as one of the brightest young scientists of his generation, Lewis Dartnell proposes that the key to preserving civilization in an apocalyptic scenario is to provide a quickstart guide, adapted to cataclysmic circumstances. The Knowledge describes many of the modern technologies we employ, but first it explains the fundamentals upon which they are built. Every piece of technology rests on an enormous support network of other technologies, all interlinked and mutually dependent. You can’t hope to build a radio, for example, without understanding how to acquire the raw materials it requires, as well as generate the electricity needed to run it. But Dartnell doesn’t just provide specific information for starting over; he also reveals the greatest invention of them all—the phenomenal knowledge-generating machine that is the scientific method itself. This would allow survivors to learn technological advances not explicitly explored in The Knowledge as well as things we have yet to discover. The Knowledge is a brilliantly original guide to the fundamentals of science and how it built our modern world as well as a thought experiment about the very idea of scientific knowledge itself.

    A decade later, despite having been an avowed opponent of the death penalty, Edison threw his laboratory resources and reputation behind the creation of a very different sort of device--the electric chair. Deftly exploring this startling chapter in American history, Edison & the Electric Chair delivers both a vivid portrait of a nation on the cusp of modernity and a provocative new examination of Edison himself.Edison championed the electric chair for reasons that remain controversial to this day. Was Edison genuinely concerned about the suffering of the condemned? Was he waging a campaign to smear his rival George Westinghouse's alternating current and boost his own system? Or was he warning the public of real dangers posed by the high-voltage alternating wires that looped above hundreds of America's streets? Plumbing the fascinating history of electricity, Mark Essig explores America's love of technology and its fascination with violent death, capturing an era when the public was mesmerized and terrified by an invisible force that produced blazing light, powered streetcars, carried telephone conversations--and killed.

    

    There he served until the war's end as Hitler's bodyguard, courier, orderly and finally as Chief of Communications. On the Berghof terrace he watched Eva Braun organize parties; observed Heinrich Himmler and Albert Speer; and monitored telephone conversations from Berlin to the East Prussian FHQ on 20 July 1944 after the attempt on Hitler's life. Towards the end Misch was drawn into the Fuhrerbunker with the last of the faithful . As defeat approached, he remained in charge of the bunker switchboard as his duty required, even after Hitler committed suicide. Misch knew Hitler as the private man and his position was one of unconditional loyalty. His memoirs offer an intimate view of life in close attendance to Hitler and of the endless hours deep inside the bunker; and provide new insights into military events such as Hitler's initial feelings that the 6th Army should pull out of Stalingrad. Shortly before he died Misch wrote a new introduction for this first-ever English-language edition.

    The theme of Heisenberg's exposition is that words and concepts familiar in daily life can lose their meaning in the world of relativity and quantum physics. This in turn has profound philosophical implications for the nature of reality and for our total world view.

    Drawing on recent scientific breakthroughs and the current cross-pollination among geology, biology, astrophysics, and cosmology, Origins explains the soul-stirring leaps in our understanding of the cosmos. From the first image of a galaxy birth to Spirit Rover's exploration of Mars, to the discovery of water on one of Jupiter's moons, coauthors Neil deGrasse Tyson and Donald Goldsmith conduct a galvanizing tour of the cosmos with clarity and exuberance.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    Guth’s startling theory—widely regarded as one of the most important contributions to science during the twentieth century—states that the big bang was set into motion by a period of hyper-rapid “inflation,” lasting only a billion-trillion-billionth of a second. The Inflationary Universe is the passionate story of one leading scientist’s effort to look behind the cosmic veil and explain how the universe began.

    Why is glass see-through? What makes elastic stretchy? Why does a paper clip bend? Why does any material look and behave the way it does? These are the sorts of questions that Mark Miodownik a globally-renowned materials scientist has spent his life exploring In this book he examines the materials he encounters in a typical morning, from the steel in his razor and the graphite in his pencil to the foam in his sneakers and the concrete in a nearby skyscraper.

    But what are his inner, personal thoughts on his own spiritual life? For the first time and in his own words, the Dalai Lama charts his spiritual journey from his boyhood days in rural Tibet to his years as a monk in the capital city of Dharamsala, to his life in exile as a world leader and symbol of peace.My Spiritual Journey provides a vivid and moving portrait of the Dalai Lama’s life journey that is personal in tone but universal in scope. He explores three phases or commitments of his spiritual life — as a human being, as a Buddhist monk, and as the Dalai Lama — each of which has made him more dedicated to exploring and teaching human values and inner happiness, promoting harmony among all religions, and advocating for the civil rights and well-being of the Tibetan people.At the age of two, little Tenzin Gyatso was identified as the fourteenth incarnation of the first Dalai Lama. From then on, his life has been a trajectory few can imagine. Some see him as a living Buddha and moral authority, others identify him as a “god-king,” which still others see him in political terms as either a hero or a counterrevolutionary. In My Spiritual Journey, we see the personal struggles, the courage, the laughter, and the compassion that have defined the remarkable life of one of our world’s greatest living legends.

    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.

    In those twelve months, Einstein shattered many cherished scientific beliefs with five extraordinary papers that would establish him as the world's leading physicist. This book brings those papers together in an accessible format. The best-known papers are the two that founded special relativity: On the Electrodynamics of Moving Bodies and Does the Inertia of a Body Depend on Its Energy Content? In the former, Einstein showed that absolute time had to be replaced by a new absolute: the speed of light. In the second, he asserted the equivalence of mass and energy, which would lead to the famous formula E = mc2.The book also includes On a Heuristic Point of View Concerning the Production and Transformation of Light, in which Einstein challenged the wave theory of light, suggesting that light could also be regarded as a collection of particles. This helped to open the door to a whole new world--that of quantum physics. For ideas in this paper, he won the Nobel Prize in 1921.The fourth paper also led to a Nobel Prize, although for another scientist, Jean Perrin. On the Movement of Small Particles Suspended in Stationary Liquids Required by the Molecular-Kinetic Theory of Heat concerns the Brownian motion of such particles. With profound insight, Einstein blended ideas from kinetic theory and classical hydrodynamics to derive an equation for the mean free path of such particles as a function of the time, which Perrin confirmed experimentally. The fifth paper, A New Determination of Molecular Dimensions, was Einstein's doctoral dissertation, and remains among his most cited articles. It shows how to calculate Avogadro's number and the size of molecules.These papers, presented in a modern English translation, are essential reading for any physicist, mathematician, or astrophysicist. Far more than just a collection of scientific articles, this book presents work that is among the high points of human achievement and marks a watershed in the history of science. Coinciding with the 100th anniversary of the miraculous year, this new paperback edition includes an introduction by John Stachel, which focuses on the personal aspects of Einstein's youth that facilitated and led up to the miraculous year.
