And two giants at the foundations of modern science were converging, step-by-step, on the answer: Albert Einstein, an young, obscure German physicist experimenting with measuring time using telegraph networks and with the coordination of clocks at train stations; and the renowned mathematician Henri Poincaré, president of the French Bureau of Longitude, mapping time coordinates across continents. Each found that to understand the newly global world, he had to determine whether there existed a pure time in which simultaneity was absolute or whether time was relative.Esteemed historian of science Peter Galison has culled new information from rarely seen photographs, forgotten patents, and unexplored archives to tell the fascinating story of two scientists whose concrete, professional preoccupations engaged them in a silent race toward a theory that would conquer the empire of time.

    It produced a cloud of roiling debris that blackened the sky for months as well as other geologic disasters--and triggered the demise of Tyrannosaurus rex. We know what happened largely because Walter Alvarez--synthesizing the findings of experts from a variety of scientific fields--has written a gripping story of the decades-long search for the cause of the dinosaurs' extinction. Painstakingly assembling clues from the Italian Apennines and the depths of the Pacific and presenting them with the excitement of a great novel, T. rex and the Crater of Doom is a book of undeniable importance and irresistible appeal by a major figure in contemporary science. " Engaging and witty. Read Alvarez for and excellent account of how scientists pose questions and seek to solve them." --Scientific American " First-rate...Alvarez provides the up-close tale of the comet or asteroid that wiped out the dinosaurs." --San Francisco Chronicle

    But, Alex Bellos says, "math can be inspiring and brilliantly creative. Mathematical thought is one of the great achievements of the human race, and arguably the foundation of all human progress. The world of mathematics is a remarkable place."Bellos has traveled all around the globe and has plunged into history to uncover fascinating stories of mathematical achievement, from the breakthroughs of Euclid, the greatest mathematician of all time, to the creations of the Zen master of origami, one of the hottest areas of mathematical work today. Taking us into the wilds of the Amazon, he tells the story of a tribe there who can count only to five and reports on the latest findings about the math instinct--including the revelation that ants can actually count how many steps they've taken. Journeying to the Bay of Bengal, he interviews a Hindu sage about the brilliant mathematical insights of the Buddha, while in Japan he visits the godfather of Sudoku and introduces the brainteasing delights of mathematical games.Exploring the mysteries of randomness, he explains why it is impossible for our iPods to truly randomly select songs. In probing the many intrigues of that most beloved of numbers, pi, he visits with two brothers so obsessed with the elusive number that they built a supercomputer in their Manhattan apartment to study it. Throughout, the journey is enhanced with a wealth of intriguing illustrations, such as of the clever puzzles known as tangrams and the crochet creation of an American math professor who suddenly realized one day that she could knit a representation of higher dimensional space that no one had been able to visualize. Whether writing about how algebra solved Swedish traffic problems, visiting the Mental Calculation World Cup to disclose the secrets of lightning calculation, or exploring the links between pineapples and beautiful teeth, Bellos is a wonderfully engaging guide who never fails to delight even as he edifies. "Here's Looking at Euclid "is a rare gem that brings the beauty of math to life.

    The manuscript was a palimpsest-a book made from an earlier codex whose script had been scraped off and the pages used again. Behind the script of the thirteenth-century monk's prayer book, the palimpsest revealed the faint writing of a much older, tenth-century manuscript. Part archaeological detective story, part science, and part history, The Archimedes Codex tells the extraordinary story of this lost manuscript, from its tenth-century creation in Constantinople to the auction block at Christie's, and how a team of scholars used the latest imaging technology to reveal and decipher the original text. What they found was the earliest surviving manuscript by Archimedes (287 b.c.-212 b.c.), the greatest mathematician of antiquity-a manuscript that revealed, for the first time, the full range of his mathematical genius, which was two thousand years ahead of modern science.

    A defiant atheist, Chapman is confronted not only by the fundamentalist beliefs that continue to banish the theory of evolution but by his own spiritual malaise as the outward journey becomes an inward quest, a tragicomic "accidental memoir"."First there was Charles Darwin, two yards long and nobody's fool. Then there was his son, my great-grandfather, Sir Francis Darwin, an eminent botanist. Then came my grandmother Frances, a modest poet who spent a considerable amount of time in rest-homes for depression From her issued my beloved mother, Clare, who was extremely short, failed to complete medical school, and eventually became an alcoholic. Then we get down to me. I'm in the movie business."Trials of the Monkey combines travel writing and reportage, as Chapman records his encounters in the South, with history and the accidental memoir of a man full of mid-life doubts in a genre-breaking first book that is darkly funny, provocative and poignant.

    Priestley represented a unique synthesis: by the 1780s, he had established himself as one of the world's most celebrated scientists, most prominent religious figures, and most outspoken political thinkers. Yet he would also have become one of the most hated men in all of his native England. When an angry mob burned down his house in Birmingham, Priestley and his family set sail for Pennsylvania.In the nascent United States, Priestley hoped to find the freedom to bridge the disciplines that had governed his life, to find a quiet lab and a receptive pulpit. Once he arrived, as a result of his close relationships with the Founding Fathers—Jefferson credited Priestley as the man who prevented him from abandoning Christianity—Priestley found himself at the center of what would go down as one of the seminal debates in American history. And as Johnson brilliant charts, Priestley exerted profound if little-known influence on the shape and course of this great experiment in nation-building.As in his most recent bestselling work, The Ghost Map, Steven Johnson here uses a dramatic historical story to explore themes that have long engaged him: innovation and the way new ideas emerge and spread, and the environments that foster these breakthroughs. As he did in Everything Bad is Good for You, he upsets some fundamental assumptions about the world we live in—namely, what it means when we invoke the Founding Fathers—and replaces them with a clear-eyed, eloquent assessment of where we stand today.

    Not until the nineteenth century would three men, armed with the best telescopes of their age, race to conquer this astronomical Everest. Parallax tells the fast-moving story of their contest, which ended in a dead heat. Against a sweeping backdrop filled with kidnappings, dramatic rescue, swordplay, madness, and bitter rivalry, Alan W. Hirshfeld brings to life the heroes -- and heroines -- of this remarkable chapter in history. Characters include the destitute boy plucked from a collapsed building who grew up to become the world's greatest telescope maker; the hot-tempered Dane whose nose was lopped off in a duel over mathematics; a merchant's apprentice forced to choose between the lure of money and his passion for astronomy; and the musician who astounded the world by discovering a new planet from his own backyard.Generously illustrated with period engravings and paintings, Parallax is an unforgettable ride through time and space.

    Called a madman by his enemies, a genius by others, and an enigma by nearly everyone, Nikola Tesla was, without a doubt, a trailblazing inventor who created astonishing, sometimes world-transforming devices that were virtually without theoretical precedent. Tesla not only discovered the rotating magnetic field -- the basis of most alternating-current machinery -- but also introduced us to the fundamentals of robotics, computers, and missile science. Almost supernaturally gifted, unfailingly flamboyant and neurotic, Tesla was troubled by an array of compulsions and phobias and was fond of extravagant, visionary experimentations. He was also a popular man-about-town, admired by men as diverse as Mark Twain and George Westinghouse, and adored by scores of society beauties. From Tesla's childhood in Yugoslavia to his death in New York in the 1940s, Cheney paints a compelling human portrait and chronicles a lifetime of discoveries that radically altered -- and continue to alter -- the world in which we live. Tesla: Man Out of Time is an in-depth look at the seminal accomplishments of a scientific wizard and a thoughtful examination of the obsessions and eccentricities of the man behind the science.

    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?

    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).

    Two of the three-Nicolaus Copernicus and Charles Darwin-are widely known and heralded for their breakthroughs. The third, James Hutton, never received the same recognition, yet he profoundly changed our understanding of the earth and its dynamic forces. Hutton proved that the earth was likely millions of years old rather than the biblically determined six thousand, and that it was continuously being shaped and re-shaped by myriad everyday forces rather than one cataclysmic event. In this expertly crafted narrative, Jack Repcheck tells the remarkable story of this Scottish gentleman farmer and how his simple observations on his small tract of land led him to a theory that was in direct confrontation with the Bible and that also provided the scientific proof that would spark Darwin's theory of evolution. It is also the story of Scotland and the Scottish Enlightenment, which brought together some of the greatest thinkers of the age, from David Hume and Adam Smith to James Watt and Erasmus Darwin. Finally, it is a story about the power of the written word. Repcheck argues that Hutton's work was lost to history because he could not describe his findings in graceful and readable prose. (Unlike Darwin's Origin of the Species, Hutton's one and only book was impenetrable.) A marvelous narrative about a little-known man and the science he founded, The Man Who Found Time is also a parable about the power of books to shape the history of ideas.

      In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.   Richard Panek tells the dramatic story of how scientists reached this conclusion, and what they’re doing to find this "dark" matter and an even more bizarre substance called dark energy. Based on in-depth, on-site reporting and hundreds of interviews—with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin—the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.

    Pluto is entrenched in our cultural and emotional view of the cosmos, and Neil deGrasse Tyson, award-winning author and director of the Rose Center, is on a quest to discover why. He stood at the heart of the controversy over Pluto's demotion, and consequently Plutophiles have freely shared their opinions with him, including endless hate mail from third-graders. With his inimitable wit, Tyson delivers a minihistory of planets, describes the oversized characters of the people who study them, and recounts how America's favorite planet was ousted from the cosmic hub.

    Nobel laureate Murray Gell-Mann offers a uniquely personal and unifying vision of the relationship between the fundamental laws of physics and the complexity and diversity of the natural world.

    From its inception, Margaret Wertheim shows, physics has been an overwhelmingly male-dominated activity; she argues that gender inequity in physics is a result of the religious origins of the enterprise.Pythagoras' Trousers is a highly original history of one of science's most powerful disciplines. It is also a passionate argument for the need to involve both women and men in the process of shaping the technologies from the next generation of physicists.
