    The Invisible Rainbow is the groundbreaking story of electricity as it's never been told before--exposing its very real impact on the biosphere and human health.100,000 copies sold!Over the last 220 years, society has evolved a universal belief that electricity is 'safe' for humanity and the planet. Scientist and journalist Arthur Firstenberg disrupts this conviction by telling the story of electricity in a way it has never been told before--from an environmental point of view--by detailing the effects that this fundamental societal building block has had on our health and our planet.In The Invisible Rainbow, Firstenberg traces the history of electricity from the early eighteenth century to the present, making a compelling case that many environmental problems, as well as the major diseases of industrialized civilization--heart disease, diabetes, and cancer--are related to electrical pollution.Few individuals today are able to grasp the entirety of a scientific subject and present it in a highly engaging manner . . . Firstenberg has done just that with one of the most pressing but neglected problems of our technological age.--BRADLEY JOHNSON, MD, Amen Clinic, San Francisco[A] masterpiece.--Celia Farber, investigative journalistThis seminal book...will transform your understanding ...of the environmental and health effects of electricity and radio frequencies--Paradigm Explorer

    But movies, TV shows, and other reporting about marriage never feature that fact. • Do we have less free time than we used to? Countless news stories and anecdotes from friends and family make the overwhelming case that we're running ourselves ragged. But when people actually keep track of their activities in a time diary, studies show that we have significantly more free time per day than in 1965. So why is everyone out of time?• Surburban sprawl is ruining America. Huge subdivisions and massive highway construction is eating up our free space and affecting our quality of life. Isn't that what you always hear? So why do you never hear that 95% of America is undeveloped, or that so-called 'smart development' prices lower-income families out of property ownership?• Also: Does shaving make your hair grow back thicker? Do girls feel more pressure to have sex than boys? Are gas prices really through the roof? Is outsourcing bad for American workers?John Stossel takes on these and many more misconceptions, misunderstandings, and plain old stupidity in this collection that will offer much to love for old GIVE ME A BREAK fans, and show everyone why conventional wisdom--economic, political, or social--is wrong.

    Its traditions serve as a record of our past. A ballerina dancing The Sleeping Beauty today is a link in a long chain of dancers stretching back to sixteenth-century Italy and France: Her graceful movements recall a lost world of courts, kings, and aristocracy, but her steps and gestures are also marked by the dramatic changes in dance and culture that followed. Ballet has been shaped by the Renaissance and Classicism, the Enlightenment and Romanticism, Bolshevism, Modernism, and the Cold War. Apollo’s Angels is a groundbreaking work—the first cultural history of ballet ever written, lavishly illustrated and beautifully told.Ballet is unique: It has no written texts or standardized notation. It is a storytelling art passed on from teacher to student. The steps are never just the steps—they are a living, breathing document of a culture and a tradition. And while ballet’s language is shared by dancers everywhere, its artists have developed distinct national styles. French, Italian, Danish, Russian, English, and American traditions each have their own expression, often formed in response to political and societal upheavals.From ballet’s origins in the Renaissance and the codification of its basic steps and positions under France’s Louis XIV (himself an avid dancer), the art form wound its way through the courts of Europe, from Paris and Milan to Vienna and St. Petersburg. It was in Russia that dance developed into the form most familiar to American audiences: The Sleeping Beauty, Swan Lake, and The Nutcracker originated at the Imperial court. In the twentieth century, émigré dancers taught their art to a generation in the United States and in Western Europe, setting off a new and radical transformation of dance. Jennifer Homans is a historian and critic who was also a professional dancer: She brings to Apollo’s Angels a knowledge of dance born of dedicated practice. She traces the evolution of technique, choreography, and performance in clean, clear prose, drawing readers into the intricacies of the art with vivid descriptions of dances and the artists who made them. Her admiration and love for the ballet shines through on every page. Apollo’s Angels is an authoritative work, written with a grace and elegance befitting its subject.

    What makes an operating system modern? According to author Andrew Tanenbaum, it is the awareness of high-demand computer applications--primarily in the areas of multimedia, parallel and distributed computing, and security. The development of faster and more advanced hardware has driven progress in software, including enhancements to the operating system. It is one thing to run an old operating system on current hardware, and another to effectively leverage current hardware to best serve modern software applications. If you don't believe it, install Windows 3.0 on a modern PC and try surfing the Internet or burning a CD. Readers familiar with Tanenbaum's previous text, Operating Systems, know the author is a great proponent of simple design and hands-on experimentation. His earlier book came bundled with the source code for an operating system called Minux, a simple variant of Unix and the platform used by Linus Torvalds to develop Linux. Although this book does not come with any source code, he illustrates many of his points with code fragments (C, usually with Unix system calls). The first half of Modern Operating Systems focuses on traditional operating systems concepts: processes, deadlocks, memory management, I/O, and file systems. There is nothing groundbreaking in these early chapters, but all topics are well covered, each including sections on current research and a set of student problems. It is enlightening to read Tanenbaum's explanations of the design decisions made by past operating systems gurus, including his view that additional research on the problem of deadlocks is impractical except for "keeping otherwise unemployed graph theorists off the streets." It is the second half of the book that differentiates itself from older operating systems texts. Here, each chapter describes an element of what constitutes a modern operating system--awareness of multimedia applications, multiple processors, computer networks, and a high level of security. The chapter on multimedia functionality focuses on such features as handling massive files and providing video-on-demand. Included in the discussion on multiprocessor platforms are clustered computers and distributed computing. Finally, the importance of security is discussed--a lively enumeration of the scores of ways operating systems can be vulnerable to attack, from password security to computer viruses and Internet worms. Included at the end of the book are case studies of two popular operating systems: Unix/Linux and Windows 2000. There is a bias toward the Unix/Linux approach, not surprising given the author's experience and academic bent, but this bias does not detract from Tanenbaum's analysis. Both operating systems are dissected, describing how each implements processes, file systems, memory management, and other operating system fundamentals. Tanenbaum's mantra is simple, accessible operating system design. Given that modern operating systems have extensive features, he is forced to reconcile physical size with simplicity. Toward this end, he makes frequent references to the Frederick Brooks classic The Mythical Man-Month for wisdom on managing large, complex software development projects. He finds both Windows 2000 and Unix/Linux guilty of being too complicated--with a particular skewering of Windows 2000 and its "mammoth Win32 API." A primary culprit is the attempt to make operating systems more "user-friendly," which Tanenbaum views as an excuse for bloated code. The solution is to have smart people, the smallest possible team, and well-defined interactions between various operating systems components. Future operating system design will benefit if the advice in this book is taken to heart. --Pete Ostenson

    It defines our experience of the world; it echoes through our every waking hour. Time is the very foundation of conscious experience. Yet as familiar as it is, time is also deeply mysterious. We cannot see, hear, smell, taste, or touch it. Yet we do "feel" it--or at least we "think" we feel it. No wonder poets, writers, philosophers, and scientists have grappled with time for centuries.In his latest book, award-winning science writer Dan Falk chronicles the story of how humans have come to understand time over the millennia, and by drawing from the latest research in physics, psychology, and other fields, Falk shows how that understanding continues to evolve. "In Search of Time" begins with our earliest ancestors' perception of time and the discoveries that led--with much effort--to the Gregorian calendar, atomic clocks, and "leap seconds." Falk examines the workings of memory, the brain's remarkable "bridge across time," and asks whether humans are unique in their ability to recall the past and imagine the future. He explores the possibility of time travel, and the paradoxes it seems to entail. Falk looks at the quest to comprehend the beginning of time and how time--and the universe--may end. Finally, he examines the puzzle of time's "flow," and the remarkable possibility that the passage of time may be an illusion.Entertaining, illuminating, and ultimately thought provoking, "In Search of Time "reveals what some of our most insightful thinkers have had to say about time, from Aristotle to Kant, from Newton to Einstein, and continuing with the brightest minds of today.
