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.

    George's parents, who have always been wary of technology, warn him about their new neighbors: Eric is a scientist and his daughter, Annie, seems to be following in his footsteps. But when George befriends them and Cosmos, their super-computer, he finds himself on a wildly fun adventure, while learning about physics, time, and the universe. With Cosmos's help, he can travel to other planets and a black hole. But what would happen if the wrong people got their hands on Cosmos? George, Annie, and Eric aren't about to find out, and what ensues is a funny adventure that clearly explains the mysteries of science. Garry Parsons' energetic illustrations add humor and interest, and his scientific drawings add clarity; there are also eight 4-page full-color inserts of scientific photos.

    Gleick's story begins at the turn of the twentieth century with the young H. G. Wells writing and rewriting the fantastic tale that became his first book, an international sensation, The Time Machine. A host of forces were converging to transmute the human understanding of time, some philosophical and some technological the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks. Gleick tracks the evolution of time travel as an idea in the culture from Marcel Proust to Doctor Who, from Woody Allen to Jorge Luis Borges. He explores the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that is unsettling our own moment: the instantaneous wired world, with its all-consuming present and vanishing future.

    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.

    The work of English clergyman, educator and Shakespearean scholar Edwin A. Abbott (1838-1926), it describes the journeys of A. Square [sic – ed.], a mathematician and resident of the two-dimensional Flatland, where women-thin, straight lines-are the lowliest of shapes, and where men may have any number of sides, depending on their social status.Through strange occurrences that bring him into contact with a host of geometric forms, Square has adventures in Spaceland (three dimensions), Lineland (one dimension) and Pointland (no dimensions) and ultimately entertains thoughts of visiting a land of four dimensions—a revolutionary idea for which he is returned to his two-dimensional world. Charmingly illustrated by the author, Flatland is not only fascinating reading, it is still a first-rate fictional introduction to the concept of the multiple dimensions of space. "Instructive, entertaining, and stimulating to the imagination." — Mathematics Teacher.

    The Steampunk Bible is the first compendium about the movement, tracing its roots in the works of Jules Verne and H. G. Wells through its most recent expression in movies such as Sherlock Holmes.

    During the brief span of just one decade, hundreds of millions of perfectly ordinary people made history: they became the only ones who would remember what it was like when the Harry Potter saga was still unfinished. What is was like to seek out friends, families, online forums, fan fiction, and podcasts to get a fix between novels. When the potential death of a character was a hotter bet than the World Series. When the unfolding story of a boy wizard changed the way books are read for all time. And a webmistress of the Leaky Cauldron, one of the most popular Harry Potter sites on the Internet, Melissa Anelli had a front row seat to it all. Whether it was helping Scholastic stop leaks and track down counterfeiters, hosting live PotterCasts at bookstores across the country, touring with the wizard rock band Harry and the Potters, or traveling to Edinburgh to interview J.K. Rowling personally, Melissa was at the center of the Harry Potter tornado, and nothing about her life would ever be the same. The Harry Potter books are a triumph of the imagination that did far more than break sales records for all time. They restored the world's sense of wonder and took on a magical life of their own. Now the series has ended, but the story is not over. With remembrances from J.K. Rowling's editors, agents, publicists, fans and Rowling herself, Melissa Anelli takes us on a personal journey through every aspect of the Harry Potter phenomenon--from his very first spell to his lasting impact on the way we live the dream.

    The Universe, of course, is our own. And Roundworld is Earth. As the wizards watch their accidental creation grow, we follow the story of our universe from the primal singularity of the Big Bang to the Internet and beyond. Through this original Terry Pratchett story (with intervening chapters from Cohen and Stewart) we discover how puny and insignificant individual lives are against a cosmic backdrop of creation and disaster. Yet, paradoxically, we see how the richness of a universe based on rules, has led to a complex world and at least one species that tried to get a grip of what was going on.

"--New York Times Book Review""Today's science fiction is often tomorrow's science fact. The physics that underlies "Star Trek" is surely worth investigating. To confine our attention to terrestrial matters would be to limit the human spirit."--Stephen Hawking (in the foreword)A

    S. Lewis's famed but apparently disorganised Chronicles of Narnia have an underlying symbolic coherence, pointing to such possible unifying themes as the seven sacraments, the seven deadly sins, and the seven books of Spenser's Faerie Queene. None of these explanations has won general acceptance and the structure of Narnia's symbolism has remained a mystery.Michael Ward has finally solved the enigma. In Planet Narnia he demonstrates that medieval cosmology, a subject which fascinated Lewis throughout his life, provides the imaginative key to the seven novels. Drawing on the whole range of Lewis's writings (including previously unpublished drafts of the Chronicles), Ward reveals how the Narnia stories were designed to express the characteristics of the seven medieval planets - - Jupiter, Mars, Sol, Luna, Mercury, Venus, and Saturn - - planets which Lewis described as "spiritual symbols of permanent value" and "especially worthwhile in our own generation." Using these seven symbols, Lewis secretly constructed the Chronicles so that in each book the plot-line, the ornamental details, and, most important, the portrayal of the Christ-figure of Aslan, all serve to communicate the governing planetary personality. The cosmological theme of each Chronicle is what Lewis called 'the kappa element in romance', the atmospheric essence of a story, everywhere present but nowhere explicit. The reader inhabits this atmosphere and thus imaginatively gains connaitre knowledge of the spiritual character which the tale was created to embody.Planet Narnia is a ground-breaking study that will provoke a major revaluation not only of the Chronicles, but of Lewis's whole literary and theological outlook. Ward uncovers a much subtler writer and thinker than has previously been recognized, whose central interests were hiddenness, immanence, and knowledge by acquaintance."
