Its author's engaging voice is one reason, and the compelling subjects he addresses is another; the nature of space and time, the role of God in creation, the history and future of the universe. But it is also true that in the years since its publication, readers have repeatedly told Professor Hawking of their great difficulty in understanding some of the book's most important concepts. This is the origin of and the reason for A Briefer History of Time: its author's wish to make its content more accessible to readers - as well as to bring it up-to-date with the latest scientific observations and findings.Although this book is literally somewhat "briefer", it actually expands on the great subjects of the original. Purely technical concepts, such as the mathematics of chaotic boundary conditions, are gone. Conversely, subjects of wide interest that were difficult to follow because they were interspersed throughout the book have now been given entire chapters of their own, including relativity, curved space, and quantum theory.This reorganization has allowed the authors to expand areas of special interest and recent progress, from the latest developments in string theory to exciting developments in the search for a complete unified theory of all the forces of physics. Like prior editions of the book - but even more so - A Briefer History of Time will guide nonscientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space. Thirty-seven full-color illustrations enhance the text and make A Briefer History of Time an exhilarating addition in its own right to the literature of science.

    The news is full of archaeology: treasures found (British king under parking lot) and treasures lost (looters, bulldozers, natural disaster, and war). Archaeological research tantalizes us with possibilities (are modern humans really part Neandertal?). Where are the archaeologists behind these stories? What kind of work do they actually do, and why does it matter?Marilyn Johnson’s Lives in Ruins is an absorbing and entertaining look at the lives of contemporary archaeologists as they sweat under the sun for clues to the puzzle of our past. Johnson digs and drinks alongside archaeologists, chases them through the Mediterranean, the Caribbean, and even Machu Picchu, and excavates their lives. Her subjects share stories we rarely read in history books, about slaves and Ice Age hunters, ordinary soldiers of the American Revolution, children of the first century, Chinese woman warriors, sunken fleets, mummies.What drives these archaeologists is not the money (meager) or the jobs (scarce) or the working conditions (dangerous), but their passion for the stories that would otherwise be buried and lost.

    It’s a staple of small talk, the app on our smartphones, and often the first thing we check each morning. Yet behind these quotidian interactions is one of the most expansive machines human beings have ever constructed—a triumph of science, technology and global cooperation. But what is this ‘weather machine’ and who created it? In The Weather Machine, Andrew Blum takes readers on a fascinating journey through an everyday miracle. In a quest to understand how the forecast works, he visits old weather stations and watches new satellites blast off. He follows the dogged efforts of scientists to create a supercomputer model of the atmosphere and traces the surprising history of the algorithms that power their work. He discovers that we have quietly entered a golden age of meteorology—our tools allow us to predict weather more accurately than ever, and yet we haven’t learned to trust them, nor can we guarantee the fragile international alliances that allow our modern weather machine to exist.Written with the sharp wit and infectious curiosity Andrew Blum is known for, The Weather Machine pulls back the curtain on a universal part of our everyday lives, illuminating our relationships with technology, the planet, and the global community.

    From menacing moonshiners and armed bandits to charging elephants and man-eating tigers, Merlin Tuttle has stopped at nothing to find and protect bats on every continent they inhabit. Enamored of bats ever since discovering a colony in a cave as a boy, Tuttle saw how effective photography could be in persuading people not to fear bats, and he has spent his career traveling the world to document them.Few people realize how sophisticated and intelligent bats are. Tuttle shares research showing that frog-eating bats can identify frogs by their calls, that vampire bats have a social order similar to that of primates, and that bats have remarkable memories. Bats also provide enormous benefits by eating crop pests, pollinating plants, and carrying seeds needed for reforestation. They save farmers billions of dollars annually and are essential to a healthy planet.Sharing highlights from a lifetime of adventure and discovery, Tuttle takes us to the frontiers of bat research and conservation and forever changes the way we see these poorly understood yet fascinating creatures.

    Much like human families, tree parents live together with their children, communicate with them, and support them as they grow, sharing nutrients with those who are sick or struggling and creating an ecosystem that mitigates the impact of extremes of heat and cold for the whole group. As a result of such interactions, trees in a family or community are protected and can live to be very old. In contrast, solitary trees, like street kids, have a tough time of it and in most cases die much earlier than those in a group.Drawing on groundbreaking new discoveries, Wohlleben presents the science behind the secret and previously unknown life of trees and their communication abilities; he describes how these discoveries have informed his own practices in the forest around him. As he says, a happy forest is a healthy forest, and he believes that eco-friendly practices not only are economically sustainable but also benefit the health of our planet and the mental and physical health of all who live on Earth.

    xn + yn = zn, where n represents 3, 4, 5, ...no solution"I have discovered a truly marvelous demonstration of this proposition which this margin is too narrow to contain."With these words, the seventeenth-century French mathematician Pierre de Fermat threw down the gauntlet to future generations.  What came to be known as Fermat's Last Theorem looked simple; proving it, however, became the Holy Grail of mathematics, baffling its finest minds for more than 350 years.  In Fermat's Enigma--based on the author's award-winning documentary film, which aired on PBS's "Nova"--Simon Singh tells the astonishingly entertaining story of the pursuit of that grail, and the lives that were devoted to, sacrificed for, and saved by it.  Here is a mesmerizing tale of heartbreak and mastery that will forever change your feelings about mathematics.

    After World War II, it reshaped the global order-whoever could master uranium could master the world. Marie Curie gave us hope that uranium would be a miracle panacea, but the Manhattan Project gave us reason to believe that civilization would end with apocalypse. Slave labor camps in Africa and Eastern Europe were built around mine shafts and America would knowingly send more than six hundred uranium miners to their graves in the name of national security. Fortunes have been made from this yellow dirt; massive energy grids have been run from it. Fear of it panicked the American people into supporting a questionable war with Iraq and its specter threatens to create another conflict in Iran. Now, some are hoping it can help avoid a global warming catastrophe. In "Uranium," Tom Zoellner takes readers around the globe in this intriguing look at the mineral that can sustain life or destroy it.

    From blurry vision, to crooked teeth, ACLs that tear at alarming rates and spines that seem to spend a lifetime falling apart, it's a curious thing that human beings have beaten the odds as a species. After all, we're the only survivors on our branch of the tree of life. Why is it that human mothers have such a life-endangering experience giving birth? And why are there entire medical specialties for teeth and feet? In this funny, wide-ranging and often surprising book, biologist Alex Bezzerides tells us just where we inherited our adaptable, achy, brilliant bodies in the process of evolution.The book traces the delightfully unexpected answers to these questions and many more:Why do we blink?Why don't our teeth regularly fit in our mouths?Why do women menstruate when so many other mammals don't?Why did humans stand up on two legs in the first place?

    These vast expanses provide a home to wildlife populations, a vital source of clean air and water, and a haven for recreation.Since its inception, however, America’s public land system has been embroiled in controversy—caught in the push and pull between the desire to develop the valuable resources the land holds or conserve them. Alarmed by rising tensions over the use of these lands, hunter, angler, and outdoor enthusiast Mark Kenyon set out to explore the spaces involved in this heated debate, and learn firsthand how they came to be and what their future might hold.Part travelogue and part historical examination, That Wild Country invites readers on an intimate tour of the wondrous wild and public places that are a uniquely profound and endangered part of the American landscape.

    

    To find a meal, the female bolas spider releases pheromones that mimic a female moth, luring male moths into her sticky lasso web. The Glyptapanteles wasp injects a caterpillar with her young, which feed on the victim, erupt out of it, then mind-control the poor (and somehow still living) schmuck into protecting them from predators.These are among the curious critters of The Wasp That Brainwashed the Caterpillar, a jaunt through evolution’s most unbelievable, most ingenious solutions to the problems of everyday life, from trying to get laid to finding food. Join Wired science writer Matt Simon as he introduces you to the creatures that have it figured out, the ones that joust with their mustaches or choke sharks to death with snot, all in a wild struggle to survive and, of course, find true love.

    On March 27, 1964, at 5:36 p.m., the biggest earthquake ever recorded in North America—and the second biggest ever in the world, measuring 9.2 on the Richter scale—struck Alaska, devastating coastal towns and villages and killing more than 130 people in what was then a relatively sparsely populated region. In a riveting tale about the almost unimaginable brute force of nature, New York Times science journalist Henry Fountain, in his first trade book, re-creates the lives of the villagers and townspeople living in Chenega, Anchorage, and Valdez; describes the sheer beauty of the geology of the region, with its towering peaks and 20-mile-long glaciers; and reveals the impact of the quake on the towns, the buildings, and the lives of the inhabitants. George Plafker, a geologist for the U.S. Geological Survey with years of experience scouring the Alaskan wilderness, is asked to investigate the Prince William Sound region in the aftermath of the quake, to better understand its origins. His work confirmed the then controversial theory of plate tectonics that explained how and why such deadly quakes occur, and how we can plan for the next one.

    Using the latest genetic and anthropological data, Spencer Wells demonstrates that although humankind's decision to control our own food supply is what propelled us into the modern world, it had many downsides that we're just now beginning to recognize.

    The name dinosaur was coined in 1842 by an English anatomist Richard Owen, a highly ambitious, machiavellian schemer and villain of Deborah Cadbury's The Dinosaur Hunters: A True Story of Scientific Rivalry and the Discovery of the Prehistoric World. Her hero is Gideon Mantell, a practising doctor, who found and first described many of the bones of the beasts that subsequently became known as dinosaurs. Full of quotes from contemporary sources, The Dinosaur Hunters brilliantly evokes the Dickensian world of early Victorian science and society. From Mary Anning, the self-taught fossil hunter of Lyme Regis to the academic and deeply eccentric Dean Buckland of Oxford University, the story tells of reputations made and lost as self-help, self-promotion, over-wheening pride, folly and social climbing all played their part in the emerging story of the geological past. The dinosaurs, although central to the story, are also a vehicle for the much larger, more interesting and important story about the struggle to understand the meaning of fossils and what they tell us about prehistory. Deborah Cadbury, an award-winning TV science producer and acclaimed author of The Feminisation of Nature has thoroughly researched her topic and steeped herself in the intricacies of the scientific debates of the time. With black and white illustrations, extensive notes, a bibliography and index, the result is one of the best popular science histories. --Douglas Palmer.
