“A marvelously readable and level-headed explanation of basic science and how it relates to the issues.” —John Tierney, New York TimesThis is “must-have” information for all presidents—and citizens—of the twenty-first century: Is Iran’s nascent nuclear capability a genuine threat to the West? Are biochemical weapons likely to be developed by terrorists? Are there viable alternatives to fossil fuels that should be nurtured and supported by the government? Should nuclear power be encouraged? Can global warming be stopped?

    In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy.   Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks readers to imagine—and choose among—five scenarios for finding life. He encourages us to wonder whether life might exist within Mars’s subsoil ice. He reveals the vital possibilities on the water-ice moons Europa and Enceladus. He views Saturn’s moon Titan through the lens of our own planet’s ancient past. And, he even looks beyond our solar system, investigating the top candidates for a “second Earth” in a myriad of exoplanets and imagining the case of a radio signal arriving from deep space. Covering the most up-to-date research, this accessibly written book provides readers with the basic knowledge necessary to decide where they would look for alien life.

    The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring readers on a marvelous experimental voyage through the possibilities of life--unlike anything we have experienced so far--that could exist on planets outside our own solar system.Life could be out there in many forms: on frozen worlds, living in liquid oceans beneath ice and communicating (and even battling) with bubbles; on super-dense planets, where they would have evolved body types capable of dealing with extreme gravity; on tidally locked planets with one side turned eternally toward a star; and even on "rogue worlds," which have no star at all. Yet this is no fictional flight of fancy: the authors take what we know about exoplanets and life on our own world and use that data to hypothesize about how, where, and which sorts of life might develop. Imagined Life is a must-have for anyone wanting to learn how the realities of our universe may turn out to be far stranger than fiction.

    If you sit as still as you can in a quiet room, you might be able to convince yourself that nothing is moving. But air currents are still wafting around you. Blood rushes through your veins. The atoms in your chair jiggle furiously. In fact, the planet you are sitting on is whizzing through space thirty-five times faster than the speed of sound. Natural motion dominates our lives and the intricate mechanics of the world around us. In Zoom, Bob Berman explores how motion shapes every aspect of the universe, literally from the ground up. With an entertaining style and a gift for distilling the wondrous, Berman spans astronomy, geology, biology, meteorology, and the history of science, uncovering how clouds stay aloft, how the Earth's rotation curves a home run's flight, and why a mosquito's familiar whine resembles a telephone's dial tone. For readers who love to get smarter without realizing it, Zoom bursts with science writing at its best.

    Throughout these essays, which range from the creation of the Royal Society in the seventeenth century to the scientific inquiries of the Romantic generation to recent books by Daniel Kahneman and Malcolm Gladwell, he seeks to “break down the barriers that separate science from other sources of human wisdom.”  Dyson discusses twentieth-century giants of physics such as Richard Feynman, J. Robert Oppenheimer, Paul Dirac, and Steven Weinberg, many of whom he knew personally, as well as Winston Churchill’s pursuit of nuclear weapons for Britain and Wernher von Braun’s pursuit of rockets for space travel. And he takes a provocative, often politically incorrect approach to some of today’s most controversial scientific issues: global warming, the current calculations of which he thinks are probably wrong; the future of biotechnology, which he expects to dominate our lives in the next half-century as the tools to design new living creatures become available to everyone; and the flood of information in the digital age. Dyson offers fresh perspectives on the history, the philosophy, and the practice of scientific inquiry—and even on the blunders, the wild guesses and wrong theories that are also part of our struggle to understand the wonders of the natural world.

    David Grinspoon, a planetary scientist who has helped to shape modern planetary exploration, brings the subject to a new generation of readers with his reflections on the most recent developments in astrobiology, including NASA's search for life on Mars. In Lonely Planets, he investigates the big questions: How widespread are life and intelligence in the cosmos? Is life on Earth an accident or in some sense the "purpose" of this universe? And how can we, working from the Earth-centric definition of "life," even begin to think about the varieties of life-forms on other planets?Using the topic of extraterrestrial life as a mirror with which to view human beliefs, evolution, history, and aspirations, Grinspoon provides an authoritative scientific narrative of cosmic evolution, along with provocative ruminations on how we fit into the story of the universe. An accessible, lively blend of science, history, philosophy, and personal narrative, Lonely Planets reveals how the search for extraterrestrial life unites our spiritual and scientific quests for connection with the cosmos.

    Blundell illuminates the mysterious force of magnetism. For centuries, magnetism has been used for various purposes—through compasses it gave us the ability to navigate, and through motors, generators, and turbines, it has given us power. Blundell explores our understanding of electricity and magnetism, from the work of Galvani, Ampère, Faraday, and Tesla, and describes how Maxwell and Faraday's work led to the unification of electricity and magnetism—one of the most imaginative developments in theoretical physics. Finally, he discusses the relationship between magnetism and relativity, quantum magnetism, and its impact on computers and information storage, showing how magnetism has changed our fundamental understanding of the Universe.

    And as we discover countless exoplanets orbiting other stars—among them, rocky super-Earths and gaseous Hot Jupiters—we become ever more hopeful that we may come across extraterrestrial life. Yet even as we become aware of the vast numbers of planets outside our solar system, it has also become clear that Earth is exceptional. The question is: why?In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is one of the primary factors that makes it able to support life, and that nothing short of luck made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely, he shows, that chances are slim that we will ever encounter intelligent extraterrestrial others.Describing the three factors that typically control a planet’s average temperature—the heat received from its star, how much heat the planet absorbs, and the concentration of greenhouse gases in the atmosphere—Waltham paints a complex picture of how special Earth’s climate really is. He untangles the mystery of why, although these factors have shifted by such massive measures over the history of life on Earth, surface temperatures have never fluctuated so much as to make conditions hostile to life. Citing factors such as the size of our Moon and the effect of an ever-warming Sun, Waltham challenges the prevailing scientific consensus that other Earth-like planets have natural stabilizing mechanisms that allow life to flourish.A lively exploration of the stars above and the ground beneath our feet, Lucky Planet seamlessly weaves the story of Earth and the worlds orbiting other stars to give us a new perspective of the surprising role chance plays in our place in the universe.

    Weaving the history of science and technology with the fortunes of war and the stories of men and women whose discoveries brought both benefits and destruction to the world, Hitler's Scientists raises questions that are still urgent today. As science becomes embroiled in new generations of weapons of mass destruction and the war against terrorism, as advances in biotechnology outstrip traditional ethics, this powerful account of Nazi science forms a crucial commentary on the ethical role of science.

    In The Five Ages of the Universe, Adams and Laughlin demonstrate that we can now understand the complete life story of the cosmos from beginning to end. Adams and Laughlin have been hailed as the creators of the definitive long-term projection of the evolution of the universe. Their achievement is awesome in its scale and profound in its scientific breadth. But The Five Ages of the Universe is more than a handbook of the physical processes that guided our past and will shape our future; it is a truly epic story. Without leaving earth, here is a fantastic voyage to the physics of eternity. It is the only biography of the universe you will ever need.

    The first, which describes the force of gravity, is widely known: Einstein's General Theory of Relativity. But the theory that explains everything else--the Standard Model of Elementary Particles--is virtually unknown among the general public.In The Theory of Almost Everything, Robert Oerter shows how what were once thought to be separate forces of nature were combined into a single theory by some of the most brilliant minds of the twentieth century. Rich with accessible analogies and lucid prose, The Theory of Almost Everything celebrates a heretofore unsung achievement in human knowledge--and reveals the sublime structure that underlies the world as we know it.
