Advancing revelatory new ideas, following chains of evidence, the book ranges through many disciplines, from environmental sciences to molecular medicine. The result is a captivating vision of contemporary science and a humane synthesis of our place in nature. This remarkable book will redefine the way we think about the world.

    Williams any rock used as building material can tell a fascinating story. All he has to do is look at building stone in any urban center to find a range of rocks equal to any assembled by plate tectonics. In Stories in Stone, he takes you on his explorations to find 3.5-billion-year-old rock that looks like swirled pink and black taffy, a gas station made of petrified wood, and a Florida fort that has withstood 300 years of attacks and hurricanes, despite being made of a stone that has the consistency of a granola bar.In Stories in Stone, Williams also weaves in the cultural history of stone. He shows why a white, fossil-rich limestone from Indiana became the only building stone to be used in all 50 states; how in 1825, the construction of the Bunker Hill Monument led to America's first commercial railroad; and why when the same kind of marble used by Michelangelo was used on a Chicago skyscraper it warped so much after 19 years that all 44,000 panels of the stone had to be replaced. A love letter to building stone, from New England brownstone and Morton Gneiss of Minnsota to the limestone of Salem, Indiana; from granite and travertine to Carrara marble, David Willilams brings to life the stones you will see in the structures of every city, large and small. After reading his book, you will forever look at stone buildings with new eyes.

    Will temperatures rise by 2�C or 8�C over the next hundred years? Will sea levels rise by 2 or 30 feet? The only way that we can accurately answer questions like these is by looking into the distant past, for a comparison with the world long before the rise of mankind.We may currently believe that atmospheric shifts, like global warming, result from our impact on the planet, but the earth's atmosphere has been dramatically shifting since its creation. This book reveals the crucial role that plants have played in determining atmospheric change - and hence the conditions on the planet we know today. Along the way a number of fascinating puzzles arise: Why did plants evolve leaves? When and how did forests once grow on Antarctica? How did prehistoric insects manage to grow so large? The answers show the extraordinary amount plants can tell us about the history of the planet -- something that has often been overlooked amongst the preoccuputations with dinosaur bones and animal fossils.David Beerling's surprising conclusions are teased out from various lines of scientific enquiry, with evidence being brought to bear from fossil plants and animals, computer models of the atmosphere, and experimental studies. Intimately bound up with the narrative describing the dynamic evolution of climate and life through Earth's history, we find Victorian fossil hunters, intrepid polar explorers and pioneering chemists, alongside wallowing hippos, belching volcanoes, and restless landmasses.

    Two of the three-Nicolaus Copernicus and Charles Darwin-are widely known and heralded for their breakthroughs. The third, James Hutton, never received the same recognition, yet he profoundly changed our understanding of the earth and its dynamic forces. Hutton proved that the earth was likely millions of years old rather than the biblically determined six thousand, and that it was continuously being shaped and re-shaped by myriad everyday forces rather than one cataclysmic event. In this expertly crafted narrative, Jack Repcheck tells the remarkable story of this Scottish gentleman farmer and how his simple observations on his small tract of land led him to a theory that was in direct confrontation with the Bible and that also provided the scientific proof that would spark Darwin's theory of evolution. It is also the story of Scotland and the Scottish Enlightenment, which brought together some of the greatest thinkers of the age, from David Hume and Adam Smith to James Watt and Erasmus Darwin. Finally, it is a story about the power of the written word. Repcheck argues that Hutton's work was lost to history because he could not describe his findings in graceful and readable prose. (Unlike Darwin's Origin of the Species, Hutton's one and only book was impenetrable.) A marvelous narrative about a little-known man and the science he founded, The Man Who Found Time is also a parable about the power of books to shape the history of ideas.

    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.

    In this book you will find some shocking details of the great figures of science such as Newton, Galileo, Kepler, Copernicus and Kant, presented with the characteristic humor that only a popularizer of science as Sergio de Regules could bring to this wonderful collection of essays.

    Also known as the Yellowstone Earthquake, the disaster caused massive flooding and the worst landslide in the history of the Northwestern United States. In The Night the Mountain Fell author Edmund Christopherson gives us a page-turning, journalistic-style account of how the deadliest earthquake in Montana's history ultimately claimed the lives of twenty-eight people.

    After the Ice is the story of this momentous period--one in which a seemingly minor alteration in temperature could presage anything from the spread of lush woodland to the coming of apocalyptic floods--and one in which we find the origins of civilization itself.Drawing on the latest research in archaeology, human genetics, and environmental science, After the Ice takes the reader on a sweeping tour of 15,000 years of human history. Steven Mithen brings this world to life through the eyes of an imaginary modern traveler--John Lubbock, namesake of the great Victorian polymath and author of Prehistoric Times. With Lubbock, readers visit and observe communities and landscapes, experiencing prehistoric life--from aboriginal hunting parties in Tasmania, to the corralling of wild sheep in the central Sahara, to the efforts of the Guila Naquitz people in Oaxaca to combat drought with agricultural innovations.Part history, part science, part time travel, After the Ice offers an evocative and uniquely compelling portrayal of diverse cultures, lives, and landscapes that laid the foundations of the modern world.

    It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

    But in this revised version of Origins, physics professors Loren and Deborah Haarsma explore what God's Word and God's world teach us about creation, evolution, and intelligent design. Clearly explaining the science, the authors focus on areas where Christians agree. They also present the strengths and weaknesses of areas where Christians differ.Origins helps you develop a deeper understanding of the origins of the universe and sort out your own views on faith and science. Small group discussion questions follow each chapter. A companion website provides resources for further study.

    For example, the matter that comprises all stars, planets, and living things turns out to be just a fraction of what actually exists. Moreover, we think that we control our actions, but data analytics can predict, with astonishing accuracy, when we will wake up, what we will buy, and even whom we will marry.The quest to pin down what's real and what's illusory is both philosophical and scientific, a metaphysical search for ultimate reality that goes back to the ancient Greeks. For the last 400 years, this search has been increasingly guided by scientists, who create theories and test them in order to define and redefine reality. And we have developed the power to alter our own reality in major ways - to defeat diseases, compensate for disabilities, and augment our intellect with computers. Where is that trend going?Experience the thrill of this exciting quest in 36 wide-ranging lectures that touch on many aspects of the ceaseless search for reality. From the birth of the universe to brain science, discover that separating the real from the illusory is an exhilarating intellectual adventure.Scientists and philosophers are not alone in grappling, at an intellectual level, with reality. Some of the most accessible interpretations are by painters, novelists, filmmakers, and other artists whose works not only draw on the latest discoveries but also sometimes inspire them. Explore examples such as Alice in Wonderland, pointillism, cubism, surrealism, and reality TV.And since dealing with reality is an experience we all share, this course is designed for people of all backgrounds.
