In Black Bodies and Quantum Cats, science writer Jennifer Ouellette traces key developments in the field, setting descriptions of the fundamentals of physics in their historical context as well as against a broad cultural backdrop. Newton’s laws are illustrated via the film Addams Family Values, while Back to the Future demonstrates the finer points of special relativity. Poe’s "The Purloined Letter" serves to illuminate the mysterious nature of neutrinos, and Jeanette Winterson’s novel Gut Symmetries provides an elegant metaphorical framework for string theory. An enchanting and edifying read, Black Bodies and Quantum Cats shows that physics is not an arcane field of study but a profoundly human endeavor—and a fundamental part of our everyday world.

    These tiny, ghostly particles are formed by the billions in stars and pass through us constantly, unseen, at almost the speed of light. Yet half a century after their discovery, we still know less about them than all the other varieties of matter that have ever been seen. In this engaging, concise volume, renowned scientist and popular writer Frank Close gives a vivid account of the discovery of neutrinos and our growing understanding of their significance, also touching on some speculative ideas concerning the possible uses of neutrinos and their role in the early universe. Close begins with the early history of the discovery of radioactivity by Henri Becquerel and Marie and Pierre Curie, the early model of the atom by Ernest Rutherford, and problems with these early atomic models, and Wolfgang Pauli's solution to that problem by inventing the concept of neutrino (named by Enrico Fermi, neutrino being Italian for little neutron). The book describes how the confirmation of Pauli's theory didn't occur until 1956, when Clyde Cowan and Fred Reines detected neutrinos, and reveals that the first natural neutrinos were finally detected by Reines in 1965 (before that, they had only been detected in reactors or accelerators). Close takes us to research experiments miles underground that are able to track neutrinos' fleeting impact as they pass through vast pools of cadmium chloride and he explains why they are becoming of such interest to cosmologists--if we can track where a neutrino originated we will be looking into the far distant reaches of the universe. In telling the story of the neutrino, Close offers a fascinating portrait of a strand of modern physics that sheds light on everything from the workings of the atom and the power of the sun.

    

    This edition retains the scope and emphasis that have made the book very successful while adding over twenty new numerical examples and over 550 new end-of-chapter problems.

    Within the past ten years, however, mathematicians have proven that they hold the key to unlocking the mysteries of our world--and ourselves. In The Mathematics of Life, Ian Stewart provides a fascinating overview of the vital but little-recognized role mathematics has played in pulling back the curtain on the hidden complexities of the natural world--and how its contribution will be even more vital in the years ahead. In his characteristically clear and entertaining fashion, Stewart explains how mathematicians and biologists have come to work together on some of the most difficult scientific problems that the human race has ever tackled, including the nature and origin of life itself.

    

    Each idea is explained in clear, accessible language, building from the basics such as mechanics, waves and particles, to more complex topics including neutrinos, string theory and dark matter.

    Moreover, the achievements of the early people of Africa are as amazing and inspiring as the achievements of any other people.This history is much older than the Trans-Atlantic Slave Trade.The author introduces his readers to the early civilizations of Africa that existed long before the coming of the Europeans. Among these were the Songhai Empire, the Benin Empire, the Kanem-Borno Empire, the Monomotapa Empire, the Swahili Confederation, the Medieval Nubian kingdoms and the Axumite Empire.The author also introduces the ancient civilizations of Africa particularly those of the Nile Valley such as Nubia and Ancient Egypt.The book is illustrated with 18 images and maps. Finally, the book recommends other books for more in depth study.

    Tens of thousands of readers have enjoyed The Quotable Einstein and The Expanded Quotable Einstein, with translations into twenty-two languages. This updated edition--which appears on the 100th anniversary of Einstein's Special Theory of Relativity and the 50th anniversary of Einstein's death--offers more than 300 new quotations, or over 1,200 altogether. Nearly all are by Einstein himself and a few are about the self-professed lone wolf Time magazine named Man of the Century at the turn of the millennium.The New Quotable Einstein also includes a new section, On Aging, and fresh material has been added to the appendix-from a touching account by Helen Dukas of Einstein's last days to a day-by-day summary of Johanna Fantova's telephone conversations with Einstein during the final year and a half of his life.Also included are a poem called Einstein, by Robert Service; and three virtually unknown verses to the song As Time Goes By (made famous in the movie Casablanca) that refer to Einstein. New photographs have been selected to introduce each section of the book.Through well-documented quotations and supplementary information, The New Quotable Einstein provides a bigger and better biographical account of this multifaceted man-as son, husband, father, lover, scientist, philosopher, aging widower, humanitarian, and friend. It shows us even more vividly why the real and imagined Einstein continues to fascinate people across the world into the twenty-first century.300-plus new quotations, more than 1,200 in allA day-by-day summary of Johanna Fantova's phone conversations with Einstein toward the end of his lifeA touching account of Einstein's last daysA new section, On AgingThree virtually unknown original verses of the song As Time Goes By (from the movie Casablanca) that refer to EinsteinRobert Service's poem Einstein-- "New Scientist"

    In an era of the military space race, Erich von Däniken boldly proclaimed that Earth had been visited by more advanced beings early in our history. But prescientific man had no concept of space ships, so he called their vehicles “chariots,” and those driving the chariots became “gods.” Over the next five decades, von Däniken’s more than 40 books built an ever-stronger case for Earth being visited by extraterrestrial visitors. And Chariots became an international best seller, with 30 million copies sold in more than two dozen languages. Also during that time, the case for ET visitations millennia ago was being reexamined by contemporary UFO researchers, who found evidence of modern visitations. And von Däniken expanded his perspective to encompass the present. Now, he presents his long-awaited sequel to Chariots of the Gods, proclaiming that the gods never left us with all-new material to show that ancient aliens are still with us. The Gods Never Left Us contends that recent advancements in biotechnology, astrophysics, engineering, and artificial intelligence not only give us a fresh perspective on his ancient astronaut theory but actually validates it. We are—as a race—embarking on the exact same trajectory of our own interplanetary colonization, just as von Däniken suggested Earth itself was colonized. ETs are definitely at work today. And that affects all of us. Why do they do what they do? What could an extraterrestrial species possibly gain from observing us in the same way we look at ants? What have these strangers wanted for the past thousands of years? Can’t they leave us alone? And what makes it so difficult for us to acknowledge the existence of these extraterrestrials? That is what this book deals with. "Erich's newest book is a fascination journey from the ancient past into the present with a plethora of scientific evidence and documented research. As always, he ads his own "to the point" take on it all. Readers may also like that his newest work moves in a slightly different direction from his past books. A thoroughly enlightening and enjoyable Read." —Bruce Cunningham, Director, Ancient Mysteries International LLC & Publisher of Advanced Archaeology Review magazine
