In What If the Earth Had Two Moons, Neil Comins leads us on a fascinating ten-world journey as we explore what our planet would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but that won't last forever. Eventually the moons collide, with one extra-massive moon emerging after a period during which Earth sports a Saturn-like ring. This and nine and other speculative essays provide us with insights into the Earth as it exists today, while shedding new light on the burgeoning search for life on planets orbiting other stars. Appealing to adult and young adult readers alike, this book follows on the author's previous bestseller, What If the Moon Didn't Exist?, with completely new scenarios backed by the latest astronomical research.

    In The Physics of Star Wars, you’ll explore the mystical power of the Force using quantum mechanics, find out how much energy it would take for the Death Star or Starkiller Base to destroy a planet, and discover how we can potentially create our very own lightsabers.

    Unique in basing relativity on the Principle of Equivalence of Gravitation and Inertia over Riemannian geometry, this book explores relativity experiments and observational cosmology to provide a sound foundation upon which analyses can be made. Covering special and general relativity, tensor analysis, gravitation, curvature, and more, this book provides an engaging, insightful introduction to the forces that shape the universe.

    This authoritative yet accessible study is the ultimate astronomy lesson. Combining fascinating and often alarming scenarios that seem plucked from science fiction with the latest research and opinions, Plait illustrates why outer space is not as remote as most people think. Each chapter explores a different phenomenon, explaining it in easy-to-understand terms, and considering how life on earth and the planet itself would be affected should the event come to pass. Rather than sensationalizing the information, Plait analyzes the probability of these catastrophes occurring in our lifetimes and what we can do to stop them. With its entertaining tone and enlightening explanation of unfathomable concepts, Death from the Skies! will appeal to science buffs and beginners alike.

    A number of the key figures in the new edition are revised to provide a more inviting and informative treatment. The figures are broken into component parts with supporting commentary so that they can more readily see the key ideas. Material from The Flying Circus is incorporated into the chapter opener puzzlers, sample problems, examples and end-of-chapter problems to make the subject more engaging. Checkpoints enable them to check their understanding of a question with some reasoning based on the narrative or sample problem they just read. Sample Problems also demonstrate how engineers can solve problems with reasoned solutions.

    Stimulating, illuminating, and always surprising, The Big Questions challenges readers to re-evaluate their most fundamental beliefs and reveals the relationship between the loftiest philosophical quests and our everyday lives.

    Using a "physics first" approach to the subject, renowned relativist James B. Hartle provides a fluent and accessible introduction that uses a minimum of new mathematics and is illustrated with a wealth of exciting applications. KEY TOPICS: The emphasis is on the exciting phenomena of gravitational physics and the growing connection between theory and observation. The Global Positioning System, black holes, X-ray sources, pulsars, quasars, gravitational waves, the Big Bang, and the large scale structure of the universe are used to illustrate the widespread role of how general relativity describes a wealth of everyday and exotic phenomena. MARKET: For anyone interested in physics or general relativity.

    Now in its fourth edition, the work has been extensively revised, with entirely new artwork, updated examples and new pedagogical features. An interactive CD-ROM with worked examples is included.

    Hydrogen atoms will wriggle into your hair and betray where you live and what you have been drinking. The carbon in your breath will become tree trunks, and the sodium in your tears will link you to long-dead oceans. The nitrogen in your muscles will help to turn the sky blue, the phosphorus in your bones will help to turn the coastal waters of North Carolina green, the calcium in your teeth will crush your food between atoms that were mined by mushrooms, and the iron in your blood will kill microbes as it once killed a star.You will also discover that much of what death must inevitably do to your body is already happening among many of your atoms at this very moment and that, nonetheless, you and everyone else you know will always exist somewhere in the fabric of the universe.You are not only made of atoms; you are atoms, and this book, in essence, is an atomic field guide to yourself.

    Monsters are lurking in the woods, beneath the waves, and within our favorite books, films, and games--and there are good reasons why they appear so often. Monsters are manifestations of our fears and symbols of our society--not to mention they're a lot of fun--but each should serve a purpose and enhance the themes and tension in your fiction. In Writing Monsters, best-selling author Philip Athans uses classic examples from books, films, and the world around us to explore what makes monsters memorable--and terrifying. You'll learn what monsters can (and should) represent in your story and how to create monsters from the ground up. Writing Monsters includes: In-depth discussions of where monsters come from, what they symbolize, and how to best portray them in fiction Informative overviews of famous monsters, archetypes, and legendary creatures A Monster Creation Form to help you create your monster from scratch An annotated version of H.P.

    After moving to Los Angeles, he became an inveterate fanboy of movie stars, spending hours waiting at studio gates to get autographs. He would later get to know many of Hollywood's most powerful figures when he became a major screenwriter, and he details here what it was like to work for legendary directors such as John Huston and Alfred Hitchcock. And then there are all the celebrities--from heads of state like Mikhail Gorbachev to rock stars like David Bowie and the members of Kiss--who went out of their way to arrange encounters with Bradbury. But throughout that last talk, as well as the interviews collected here from earlier in his career, Bradbury constantly twists the elements of his life into a discussion of the influences and creative processes behind his remarkable developments and inventions for the literary form he mastered. Mixed with cheerful gossiping about his travels and the characters of his life, it makes for a rich reading experience and a revealing collection of interviews.
