. . a book that enriches our understanding of how the struggle to think new thoughts is shared across time and space and people.”—The Sunday Telegraph (London)Christmas, 1859. Just one month after the publication of On the Origin of Species, Charles Darwin received an unsettling letter. He had expected criticism; in fact, letters were arriving daily, most expressing outrage and accusations of heresy. But this letter was different. It accused him of failing to acknowledge his predecessors, of taking credit for a theory that had already been discovered by others. Darwin realized that he had made an error in omitting from Origin of Species any mention of his intellectual forebears. Yet when he tried to trace all of the natural philosophers who had laid the groundwork for his theory, he found that history had already forgotten many of them.Darwin’s Ghosts tells the story of the collective discovery of evolution, from Aristotle, walking the shores of Lesbos with his pupils, to Al-Jahiz, an Arab writer in the first century, from Leonardo da Vinci, searching for fossils in the mine shafts of the Tuscan hills, to Denis Diderot in Paris, exploring the origins of species while under the surveillance of the secret police, and the brilliant naturalists of the Jardin de Plantes, finding evidence for evolutionary change in the natural history collections stolen during the Napoleonic wars. Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature’s extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.With each chapter focusing on an early evolutionary thinker, Darwin’s Ghosts is a fascinating account of a diverse group of individuals who, despite the very real dangers of challenging a system in which everything was presumed to have been created perfectly by God, felt compelled to understand where we came from. Ultimately, Stott demonstrates, ideas—including evolution itself—evolve just as animals and plants do, by intermingling, toppling weaker notions, and developing over stretches of time. Darwin’s Ghosts presents a groundbreaking new theory of an idea that has changed our very understanding of who we are.

     To the author, Oxford historian Felipe Fernández-Armesto, a society's relationship to climate, geography, and ecology are paramount in determining its degree of success. "Unlike previous attempts to write the comparative history of civilizations," he writes, "it is arranged environment by environment, rather than period by period or society by society." Thus, for example, tundra civilizations of Ice Age Europe are linked with those of the Inuit of the Pacific Northwest, the Mississippi Mound Builders with the deforesters of eleventh-century Europe. Civilizations brilliantly connects the world of ecologist, geologist, and geographer with the panorama of cultural history.

    Professor Westfall treats all aspects of Newton's career, but his account centres on a full description of Newton's achievements in science. Thus the core of the work describes the development of the calculus, the experimentation that altered the direction of the science of optics, and especially the investigations in celestial dynamics that led to the law of universal gravitation.

    The Medieval Machine tells how, between the years 900 and 1300, Europeans created their first industrial revolution, which set Western civilization on the road to global dominance. Gimpel describes the main features of this early machine age: the pervasive use of waterpower (the oil of the medieval era); the agricultural innovations that energized the population through better nourishment; the spread of mining along with mechanized iron mills; and the appearance of modern industrial problems such as labor unrest and pollution. This is a story of technology triumphant: architect-engineers were adulated; there were tallest-building contests like those of the twentieth century. The climax comes with the invention of the key modern device-the mechanical clock. The subsequent technological decline, Gimpel explains, was due to plague, famine, and a reversion to mysticism.In the epilogue, Gimpel asserts that the West in his time faced another technological decline; he did not foresee the digital boom of the 1980s and 90s and the development of a post-industrial economies. Nevertheless, his predictions may provide valuable material for historians of the recent past.

    Roads bind our world--metaphorically and literally--transforming landscapes and the lives of the people who inhabit them. Roads have unparalleled power to impact communities, unite worlds and sunder them, and reveal the hopes and fears of those who travel them. With his marvelous eye for detail and his contagious enthusiasm, Ted Conover explores six of these key byways worldwide. In Peru, he traces the journey of a load of rare mahogany over the Andes to its origin, an untracked part of the Amazon basin soon to be traversed by a new east-west route across South America. In East Africa, he visits truckers whose travels have been linked to the worldwide spread of AIDS. In the West Bank, he monitors highway checkpoints with Israeli soldiers and then passes through them with Palestinians, witnessing the injustices and danger borne by both sides. He shuffles down a frozen riverbed with teenagers escaping their Himalayan valley to see how a new road will affect the now-isolated Indian region of Ladakh. From the passenger seat of a new Hyundai piling up the miles, he describes the exuberant upsurge in car culture as highways proliferate across China. And from inside an ambulance, he offers an apocalyptic but precise vision of Lagos, Nigeria, where congestion and chaos on freeways signal the rise of the global megacity. A spirited, urgent book that reveals the costs and benefits of being connected--how, from ancient Rome to the present, roads have played a crucial role in human life, advancing civilization even as they set it back.

    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).

    The author sets out not to give us the history of academic discipline but a history of choices: the choice of pasts, and the ways they have been demarcated, investigated, presented and even sometimes learned from as they have changed according to political, religious, cultural, and (often most important) partisan and patriotic circumstances. Burrow aims, as well, to change our perceptions of the crucial turning points in the history of history, allowing the ideas that historians have had about both their own times and their founding civilizations to emerge with unexpected freshness.Burrow argues that looking at the history of history is one of the most interesting ways we have to understand the past. Certainly, this volume stands alone in its ambition, scale and fascination.

    They wanted to discover how the world worked, but they also wanted credit for making those discoveries, and their personalities often affected how that credit was assigned. Gilbert Lewis, for example, could be reclusive and resentful, and his enmity with Walther Nernst may have cost him the Nobel Prize; Irving Langmuir, gregarious and charming, rediscovered Lewis's theory of the chemical bond andreceived much of the credit for it. Langmuir's personality smoothed his path to the Nobel Prize over Lewis.Coffey deals with moral and societal issues as well. These same scientists were the first to be seen by their countries as military assets. Fritz Haber, dubbed the father of chemical warfare, pioneered the use of poison gas in World War I-vividly described-and Glenn Seaborg and Harold Urey wereleaders in World War II's Manhattan Project; Urey and Linus Pauling worked for nuclear disarmament after the war. Science was not always fair, and many were excluded. The Nazis pushed Jewish scientists like Haber from their posts in the 1930s. Anti-Semitism was also a force in American chemistry, and few women were allowed in; Pauling, for example, used his influence to cut off the funding and block the publications of his rival, Dorothy Wrinch.Cathedrals of Science paints a colorful portrait of the building of modern chemistry from the late 19th to the mid-20th century.

    As he did so masterfully in Prime Obsession, Derbyshire brings the evolution of mathematical thinking to dramatic life by focusing on the key historical players. Unknown Quantity begins in the time of Abraham and Isaac and moves from Abel's proof to the higher levels of abstraction developed by Galois through modern-day advances. Derbyshire explains how a simple turn of thought from this plus this equals this to this plus what equals this? gave birth to a whole new way of perceiving the world. With a historian's narrative authority and a beloved teacher's clarity and passion, Derbyshire leads readers on an intellectually satisfying and pleasantly challenging historical and mathematical journey.

    Lovejoy points out the three principles - plenitude, continuity, and graduation - which were combined in this conception; analyzes their origins in the philosophies of Plato, Aristotle, and the Neoplatonists; traces the most important of their diverse ramifications in subsequent religious thought, in metaphysics, in ethics and aesthetics, and in astronomical and biological theories; and copiously illustrates the influence of the conception as a whole, and of the ideas out of which it was compounded, upon the imagination and feelings as expressed in literature.

    There, at its center, the fusion of 620 million tons of hydrogen every second generates an unfathomable amount of energy. By replicating even a tiny piece of the Sun’s power on Earth, we can secure all the heat and energy we would ever need.Nuclear fusion scientists have pursued this simple yet extraordinary ambition for decades. Skeptics say it will never work but, as A Piece of the Sun makes clear, large-scale nuclear fusion is scientifically possible—and has many advantages over other options. Fusion is clean, green and virtually limitless and Clery argues passionately and eloquently that the only thing keeping us from proving its worth is our politicians’ shortsightedness. The world energy industry is worth trillions of dollars, divert just a tiny fraction of that into researching fusion and we would soon know if it is workable.Timely and authoritative, A Piece of the Sun is a rousing call-to-arms to seize this chance of avoiding the looming energy crisis.

    Accepting the increasingly widespread belief that industrialized culture inevitably erodes the natural world, Endgame sets out to explore how this relationship impels us towards a revolutionary and as-yet undiscovered shift in strategy. Building on a series of simple but increasingly provocative premises, Jensen leaves us hoping for what may be inevitable: a return to agrarian communal life via the disintegration of civilization itself.

    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.

    And yet for many years it was equally baffling for scientists themselves. Manjit Kumar gives a dramatic and superbly-written history of this fundamental scientific revolution, and the divisive debate at its heart.For 60 years most physicists believed that quantum theory denied the very existence of reality itself. Yet Kumar shows how the golden age of physics ignited the greatest intellectual debate of the twentieth century.Quantum sets the science in the context of the great upheavals of the modern age. In 1925 the quantum pioneers nearly all hailed from upper-middle-class academic families; most were German; and their average age was 24. But it was their irrational, romantic spirit, formed in reaction to the mechanised slaughter of the First World War that inspired their will to test science to its limits.The essential read for anyone fascinated by this complex and thrilling story and by the band of young men at its heart.
