A strong gravitational wave will briefly change that distance by less than the thickness of a human hair. We have perhaps less than a few tenths of a second to perform this measurement. And we don’t know if this infinitesimal event will come next month, next year or perhaps in thirty years.In 1916 Einstein predicted the existence of gravitational waves: miniscule ripples in the very fabric of spacetime generated by unfathomably powerful events. If such vibrations could somehow be recorded, we could observe our universe for the first time through sound: the hissing of the Big Bang, the whale-like tunes of collapsing stars, the low tones of merging galaxies, the drumbeat of two black holes collapsing into one. For decades, astrophysicists have searched for a way of doing so…In 2016 a team of hundreds of scientists at work on a billion-dollar experiment made history when they announced the first ever detection of a gravitational wave, confirming Einstein’s prediction. This is their story, and the story of the most sensitive scientific instrument ever made: LIGO.Based on complete access to LIGO and the scientists who created it, Black Hole Blues provides a firsthand account of this astonishing achievement: a compelling, intimate portrait of cutting-edge science at its most awe-inspiring and ambitious.

    This amusing but highly informative photographic journey reveals the idiosyncrasy and inventiveness that characterize the construction of the humble toilet around the globe.

    This book traces the history of human movement and interaction around and across the world's greatest bodies of water, charting our relationship with the oceans from the time of the first voyagers. David Abulafia begins with the earliest of seafaring societies - the Polynesians of the Pacific, the possessors of intuitive navigational skills long before the invention of the compass, who by the first century were trading between their far-flung islands. By the seventh century, trading routes stretched from the coasts of Arabia and Africa to southern China and Japan, bringing together the Indian Ocean and the western Pacific and linking half the world through the international spice trade. In the Atlantic, centuries before the little kingdom of Portugal carved out its powerful, seaborne empire, many peoples sought new lands across the sea - the Bretons, the Frisians and, most notably, the Vikings, now known to be the first Europeans to reach North America. As Portuguese supremacy dwindled in the late sixteenth century, the Spanish, the Dutch and then the British each successively ruled the waves.Following merchants, explorers, pirates, cartographers and travellers in their quests for spices, gold, ivory, slaves, lands for settlement and knowledge of what lay beyond, Abulafia has created an extraordinary narrative of humanity and the oceans. From the earliest forays of peoples in hand-hewn canoes through uncharted waters to the routes now taken daily by supertankers in their thousands, The Boundless Sea shows how maritime networks came to form a continuum of interaction and interconnection across the globe: 90 per cent of global trade is still conducted by sea. This is history of the grandest scale and scope, and from a bracingly different perspective - not, as in most global histories, from the land, but from the boundless seas.

    It deals with the central problems of the human condition--with important questions of free will, morality, life after death, the limits of logic and reason--though often in rather esoteric terms. Now, in The Oxford Companion to Philosophy, readers have the most authoritative and engaging one-volume reference work on philosophy available, offering clear and reliable guidance to the ideas of all notable philosophers from antiquity to the present day, and to the major philosophical systems around the globe, from Confucianism tophenomenology. Here is indeed a world of thought, with entries on idealism and empiricism, ethics and aesthetics, epicureanism and stoicism, deism and pantheism, liberalism and conservativism, logical positivism and existentialism--over two thousand entries in all. The contributors represent a veritable who's whoof modern philosophy, including such eminent figures as Isaiah Berlin, Sissela Bok, Ronald Dworkin, John Searle, Michael Walzer, and W. V. Quine. We read Paul Feyerabend on the history of the philosophy of science, Peter Singer on Hegel, Anthony Kenny on Frege, and Anthony Quinton on philosophyitself. We meet the great thinkers--from Aristotle and Plato, to Augustine and Aquinas, to Descartes and Kant, to Nietzsche and Schopenhauer, right up to contemporary thinkers such as Richard Rorty, Jacques Derrida, Luce Iragaray, and Noam Chomsky (over 150 living philosophers are profiled). Thereare short entries on key concepts such as personal identity and the mind-body problem, major doctrines from utilitarianism to Marxism, schools of thought such as the Heidelberg School or the Vienna Circle, and contentious public issues such as abortion, capital punishment, and welfare. In addition, the book offers short explanations of philosophical terms (qualia, supervenience, iff), puzzles (the Achilles paradox, the prisoner's dilemma), and curiosities (the philosopher's stone, slime). Almost every entry is accompanied by suggestions for further reading, and the book includes both achronological chart of the history of philosophy and a gallery of portraits of eighty eminent philosophers, from Pythagoras and Confucius to Rudolf Carnap and G.E. Moore. And finally, as in all Oxford Companions, the contributors also explore lighter or more curious aspects of the subject, such asDeaths of Philosophers (quite a few were executed, including Socrates, Boethius, Giordano Bruno, and Thomas More) or Nothing so Absurd (referring to Cicero's remark that There is nothing so absurd but some philosopher has said it). Thus the Companion is both informative and a pleasure tobrowse in, providing quick answers to any question, and much intriguing reading for a Sunday afternoon. An indispensable guide and a constant source of stimulation and enlightenment, The Oxford Companion to Philosophy with appeal to everyone interested in abstract thought, the eternal questions, and the foundations of human understandin

    The military successes of European imperialism are easy to explain because in many cases they were achieved by using firearms against spears. Alfred Crosby, however, explains that the Europeans' displacement and replacement of the native peoples in the temperate zones was more a matter of biology than of military conquest. Now in a new edition with a new preface, Crosby revisits his classic work and again evaluates the ecological reasons for European expansion. Alfred W. Crosby is the author of the widely popular and ground-breaking books, The Measure of Reality (Cambridge, 1996), and America's Forgotten Pandemic (Cambridge, 1990). His books have received the Ralph Waldo Emerson Prize, the Medical Writers Association Prize and been named by the Los Angeles Times as among the best books of the year. He taught at the University of Texas, Austin for over 20 years. First Edition Hb (1986): 0-521-32009-7 First Edition Pb (1987): 0-521-33613-
