Dark matter. These strange and invisible substances don't just sound mysterious: their unexpected appearance in the cosmic census is upending long-held notions about the nature of the Universe. Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that the Universe is accelerating its expansion and that something stronger than gravity--dark energy--is at work. In Einstein's Telescope Evalyn Gates, a University of Chicago astrophysicist, transports us to the edge of contemporary science to explore the revolutionary tool that unlocks the secrets of these little-understood cosmic constituents. Based on Einstein's theory of general relativity, gravitational lensing, or "Einstein's Telescope," is enabling new discoveries that are taking us toward the next revolution in scientific thinking--one that may change forever our notions of where the Universe came from and where it is going.

    We imagine what it would be like to belong to such a family. No fights over the holidays. No getting on one another’s nerves. Respect for individual identity. Mutual support, without being intrusive. So many people believe they are disqualified from having a better family experience, primarily because they compare their own family with the mythic ideal, and their reality falls short. Is that a fair standard to judge against?” In the pages of Why Do I Love These People? , Po Bronson takes us on an extraordinary journey. It begins on a river in Texas, where a mother gets trapped underwater and has to bargain for her own life and that of her kids. Then, a father and his daughter return to their tiny rice-growing village in China, hoping to rekindle their love for each other inside the walls of his childhood home. Next, a son puts forth a riddle, asking us to understand what his first experience of God has to do with his Mexican American mother.Every step–and every family–on this journey is real. Calling upon his gift for powerful nonfiction narrative and philosophical insight, Bronson explores the incredibly complicated feelings that we have for our families. Each chapter introduces us to two people–a father and his son, a daughter and her mother, a wife and her husband–and we come to know them as intimately as characters in a novel, following the story of their relationship as they struggle resiliently through the kinds of hardships all families endure. Some of the people manage to save their relationship, while others find a better life only after letting the relationship go. From their efforts, the wisdom in this book emerges. We are left feeling emotionally raw but grounded–and better prepared to love, through both hard times and good time.In these twenty mesmerizing stories, we discover what is essential and elemental to all families and, in doing so, slowly abolish the fantasies and fictions we have about those we fight to stay connected to.In Why Do I Love These People? , Bronson shows us that we are united by our yearnings and aspirations: Family is not our dividing line, but our common ground.From the Hardcover edition.

    Despite its title, it's not wild ranting pseudo-science to be dismissed by those with brains. Rather, Amdahl maintains that one need not understand quantum physics to grasp how electricity works in practical applications. To understand your toaster or your fax machine, it doesn't really matter whether there are electrons or not, and it's a lot easier and more fun to start with the toaster than with quarks and calculus. The book is mildly weird, often funny, always clear and easy to understand. It assumes the reader doesn't know a volt from a hole in the ground and gently leads him or her through integrated circuits, radio, oscillators and the basics of the digital revolution using examples that include green buffalo, microscopic beer parties, break-dancing chickens and naked Norwegian girls in rowboats. OK, it's more than mildly weird.The book has been reprinted numerous times since 1991 and has achieved minor cult status. Reviewed and praised in dozens of electronics and educational magazines, it is used as a text by major corporations, colleges, high schools, military schools and trade schools. It has been studied by education programs at colleges across the United States. This book was making wise cracks in the corner before anyone thought of designing books for dummies and idiots; some say it helped to inspire that industry.It may be the only "introduction to electronics books" with back cover comments by Dave Barry, Ray Bradbury, Clive Cussler, and George Garrett, as well as recomendations from Robert Hazen, Bob Mostafapour, Dr. Roger Young, Dr. Wayne Green, Scott Rundle, Brian Battles, Michelle Guido, Herb Reichert and Emil Venere. As Monitoring Times said, "Perhaps the best electronics book ever. If you'd like to learn about basic electronics but haven't been able to pull it off, get There Are No Electrons. Just trust us. Get the book."

    It describes conventional and unconventional methods of electricity generation and its economics, distribution methods, substation location, electric drives, high frequency power for induction and heating, illumination engineering, and electric traction.

    In this delightful tour of the galaxies, Merlin often recounts his conversations with these historical figures in his responses to popular astronomy questions asked by adults and children alike. Merlin's well-informed answers combine a unique combination of wit and poetry along with serious science explained in refreshingly clear, reader-friendly language.Dear Merlin: Can a person cross our galaxy in a spaceship during one human lifespan?Merlin: In 1905, Merlin's good friend Albert Einstein introduced the "Special Theory of Relativity," which predicts that time will tick slower and slower the faster you travel. Were you to embark on such an adventure you could conceivably age as little as you wish, depending of course, on your exact speed. The problem arises when you return to Earth, which will have moved several hundred thousand years into the future and everyone will have forgotten about you.A skywatcher's book for lovers of the universe by one of its greatest lights.

    From the transformation on the road to Damascus of the Jew Saul into the Christian evangelist Paul to a twenty-first-century “religious marketplace” in which half of Americans have changed faiths at least once, nothing has been more important in the struggle for reason than the right to believe in the God of one’s choice or to reject belief in God altogether.   Focusing on the long, tense convergence of Judaism, Christianity, and Islam—each claiming possession of absolute truth—Jacoby examines conversions within a social and economic framework that includes theocratic coercion (unto torture and death) and the more friendly persuasion of political advantage, economic opportunism, and interreligious marriage. Moving through time, continents, and cultures—the triumph of Christianity over paganism in late antiquity, the Spanish Inquisition, John Calvin’s dour theocracy, Southern plantations where African slaves had to accept their masters’ religion—the narrative is punctuated by portraits of individual converts embodying the sacred and profane. The cast includes Augustine of Hippo; John Donne; the German Jew Edith Stein, whose conversion to Catholicism did not save her from Auschwitz; boxing champion Muhammad Ali; and former President George W. Bush. The story also encompasses conversions to rigid secular ideologies, notably Stalinist Communism, with their own truth claims.   Finally, Jacoby offers a powerful case for religious choice as a product of the secular Enlightenment. In a forthright and unsettling conclusion linking the present with the most violent parts of the West’s religious past, she reminds us that in the absence of Enlightenment values, radical Islamists are persecuting Christians, many other Muslims, and atheists in ways that recall the worst of the Middle Ages.(With 8 pages of black-and-white illustrations.)

    The mission of this extensively revised new edition is to foster student empowerment by giving students the tools they need to master the content of psychology, to think critically about student phenomenon, and to build an appreciation for how psychology can increase their understanding of the world around them. A key aspect of the revision is the incorporation of Robert Feldman's P.O.W.E.R. Learning System into the book and ancillary package. Based on empirical research carried out by learning researchers, the P.O.W.E.R. framework is a systematic approach to learning and studying based on five key steps (Prepare, Organize, Work, Evaluate, and Rethink) that aids the acquisition and retention of new material.

    Putting people into places and situations unprecedented in history is stirred the imagination while the human experience was expanding and redefining. Yet, space exploration compels humans to confront a hostile environment of cosmic radiations, radical changes in the gravity and magnetic fields, as well as social isolation. Therefore, any space traveller is submitted to relevant health-related threats. In the twenty-first century, human space flight is poised to continue, but it will enjoy the ongoing developments in science and technology. It will become more networked, more global, and more oriented toward primary goals. A novel international human space flight policy could help achieve these objectives by clarifying the rationale, the ethics of acceptable risk, the role of remote presence, and the need for balance between funding and ambition to justify the risk of human lives. In order to address such a challenge, a preliminary careful survey of the available scientific data is mandatory to set forth adequate countermeasures. Envisaged solutions should provide a sound and technically feasible approach for counteracting microgravity and cosmic rays effects, which represent the main health risk for space crews. This objective must necessarily be sustained by national/international space agencies, which would coordinate their common efforts into a defined international spaceflight program.

    Here you’ll find the facts, the processes, the physics of our complex and changing climate, but delivered with eloquence and urgency. Lawrence Krauss writes with a clarity that transcends mere politics. Prose and poetry were never better bedfellows.” —Ian McEwan, Booker Prize-winning author of Solar and Machines Like Me “Lawrence Krauss has written the ideal book for anyone interested in understanding the science of global warming. It is at once elegant, rigorous, and timely.”—Elizabeth Kolbert, staff writer, The New Yorker, and Pulitzer prize-winning author of The Sixth Extinction “A brief, brilliant, and charming summary of what physicists know about climate change and how they learned it.” —Sheldon Glashow, Nobel Laureate in Physics, Metcalf Distinguished Professor Emeritus, Boston University “The distinguished scientist Lawrence Krauss turns his penetrating gaze on the most pressing existential threat facing our world: climate change. It is brimming with information lucidly analysed. Such hope as there is lies in science, and a physicist of Dr. Krauss’s imaginative versatility is unusually qualified to offer it.” —Richard Dawkins, author of The Blind Watchmaker and Science in the Soul “Lucid and gripping, this study of the most severe challenge humans have ever faced leads the reader from the basic physics of climate change to recognition of the damage that humans have already caused and on to the prospects that lie ahead if we do not change course soon.” —Noam Chomsky, Laureate Professor, University of Arizona, author of Internationalism or Extinction? “Lawrence Krauss tells the story of climate change with erudition, urgency, and passion. It is our great good luck that one of our most brilliant scientists is also such a gifted writer. This book will change the way we think about the future.” —Jennifer Finney Boylan, author of Good Boy and She’s Not There “Everything on climate change that I’ve seen is either dumbed down and bossy or written for other climate scientists. I’ve been looking for a book that can let me, a layperson, understand the science. This book does just what I was looking for. It is important.” —Penn Jillette, Magician, author of Presto! and God, No! “The renowned physicist Lawrence Krauss makes the science behind one of the most important issues of our time accessible to all.” —Richard C. J. Somerville, Distinguished Professor Emeritus, Scripps Institution of Oceanography, University of California, San Diego “Lawrence Krauss is a fine physicist, a talented writer, and a scientist deeply engaged with public affairs. His book deserves wide readership. The book’s eloquent exposition of the science and the threats should enlighten all readers and motivate them to an urgent concern about our planet’s future.” —Lord Martin Rees, Astronomer Royal, former president of the Royal Society, author of On the Future: Prospects for Humanity
