    Yet we take supplies of clean water and secure food for granted, rarely considering the free work nature does for Britain. In fact for years we have damaged the systems that sustain us under the illusion that we are keeping prices down, through intensive farming, drainage of bogs, clearing forests and turning rivers into canals. As Tony Juniper's new analysis shows, however, the ways in which we meet our needs often doesn't make economic sense. Through vivid first hand accounts and inspirational examples of how the damage is being repaired, Juniper takes readers on a journey to a different Britain from the one many assume we inhabit, not a country where nature is worthless or an impediment to progress, but the real Britain, the one where we are supported by nature, wildlife and natural systems at almost every turn.

    It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    Intrepid explorer, careful scientist, talented writer, and dedicated conservationist, Powell led the expedition that put the Colorado River on American maps and revealed the GrandCanyon to the world. Now comes the first biography of this towering figure in almost fifty years--a book that captures his life in all its heroism, idealism, and ambivalent, ambiguous humanity. In A River Running West, Donald Worster, one of our leading Western historians, tells the story of Powell's great adventures and describes his historical significance with compelling clarity and skill. Worster paints a vivid portrait of how this man emerged from the early nineteenth-century worldof immigrants, fervent religion, and rough-and-tumble rural culture, and barely survived the Civil War battle at Shiloh. The heart of Worster's biography is Powell's epic journey down the Colorado in 1869, a tale of harrowing experiences, lethal accidents, and breathtaking discoveries. After yearsin the region collecting rocks and fossils and learning to speak the local Native American languages, Powell returned to Washington as an eloquent advocate for the West, one of America's first and most influential conservationists. But in the end, he fell victim to a clique of Western politicianswho pushed for unfettered economic development, relegating the aging explorer to a quiet life of anthropological contemplation. John Wesley Powell embodied the energy, optimism, and westward impulse of the young United States. A River Running West is a gorgeously written, magisterial account of this great American explorer and environmental pioneer, a true story of undaunted courage in the American West.

    But more than that, as Doug Macdougall makes clear, the science also provides important clues to the future of the planet. In an entertaining and accessibly written narrative, Macdougall gives an overview of Earth’s astonishing history based on information extracted from rocks, ice cores, and other natural archives. He explores such questions as: What is the risk of an asteroid striking Earth? Why does the temperature of the ocean millions of years ago matter today? How are efforts to predict earthquakes progressing? Macdougall also explains the legacy of greenhouse gases from Earth’s past and shows how that legacy shapes our understanding of today’s human-caused climate change. We find that geoscience in fact illuminates many of today’s most pressing issues—the availability of energy, access to fresh water, sustainable agriculture, maintaining biodiversity—and we discover how, by applying new technologies and ideas, we can use it to prepare for the future.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    In this thrill-ride across millennia and continents, the complete history of the planet comes to life: from the Earth's fiery birth to its near-obliteration in the Triassic period, and from the first signs of human life to the tentative future of a world with a burgeoning population and a global warming crisis. Covering a wide range of topics including astrophysics, zoology, and sociology, and complete with maps and illustrations, What on Earth Happened? In Brief is the endlessly entertaining story of the planet, life, and people.

    It was a metropolis of great cultural, economic, and political importance that dates from the beginning of the 3rd millennium BCE. Although it primarily flourished between approximately 2500 and 1500 BCE, the city had longer lasting influences on the urbanization of the Indian subcontinent for centuries after its abandonment. It is believed to have been one of two capital cities of the Indus Civilization, its twin being Harappa located further north in Punjab, Pakistan.Mohenjo-daro is an enigmatic settlement, which confuses simple definitions of what a city consists of. It has revealed little evidence of palaces, contains few definite religious buildings, and appears to have never been involved in any external or internal military conflict. The inhabitants’ writing has not been deciphered, and little is known about their religious and post-mortuary beliefs. Nonetheless, the city’s importance is epitomized by its monumental buildings and walls, enormous manmade platforms, innovative architectural techniques, and evidence that they engaged in trade over vast distances, with high-quality artifacts sent from the Indus Valley as far as Mesopotamia and even Africa. Of particular note was their ingenious drainage system –one of the earliest means by which sewage was drained out of the city. No other urban site of similar size had a hydraulic network as complex and effective as that of Mohenjo-daro, and it would only be surpassed thousands of years later by the network of aqueducts in Rome during the third century CE. For centuries this city was believed to have sprung into existence suddenly and without precedent, with a highly standardized system of urban development, art, and architecture that is emulated in contemporary settlements across the Indus River Valley in a phenomenon known as the “Pan-Indus system”. Although this view has changed over the last few decades, there exists no definitive hypothesis as to how they grew such a complex urban society so quickly. Fittingly, the city has an equally intriguing and mysterious narrative that explains its decline and eventual disappearance, a tale that gives the site its name: the “Hill of the Dead”. The Indus Valley Civilization was forgotten for millennia, until 20th century archaeologists rediscovered and began excavations at Mohenjo-daro and Harappa. Today only foundations remain, but the site’s importance is represented by its UNESCO World Heritage status, awarded in 1980 for being a site of outstanding cultural importance to the common heritage of humanity.Mohenjo-daro: The History and Legacy of the Ancient Settlement of the Indus Valley Civilization looks at the history of the site and the archaeological work on it.

    Right?! Machine Learning is a branch of computer science that wants to stop programming computers using a detailed list of commands to follow blindly. Instead, their aim is to implement high-level routines that teach computers how to approach new and unknown problems – these are called algorithms. In practice, they want to give computers the ability to Learn and to Adapt. We can use these algorithms to obtain insights, recognize patterns and make predictions from data, images, sounds or videos we have never seen before – or even knew existed. Unfortunately, the true power and applications of today’s Machine Learning Algorithms remain deeply misunderstood by most people. Through this book I want fix this confusion, I want to shed light on the most relevant Machine Learning Algorithms used in the industry. I will show you exactly how each algorithm works, why it works and when you should use it.

    It emphasizes the ways in which the study of sedimentary rocks is used to interpret depositional environments, changes in ancient sea level, and other intriguing aspects of Earth’s history.

    Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In prose that is at once frank, entertaining, and deeply informed, The New Yorker writer Elizabeth Kolbert tells us why and how human beings have altered life on the planet in a way no species has before. Interweaving research in half a dozen disciplines, descriptions of the fascinating species that have already been lost, and the history of extinction as a concept, Kolbert provides a moving and comprehensive account of the disappearances occurring before our very eyes. She shows that the sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human.

    Surprisingly, a great many players surveyed did not even know you need to hit down to get the ball up in the air. Hit Down @#!*% ! concisely explains the concept - and the technique - of hitting down at the golf ball for proper trajectory, increased backspin, much improved distance, proper divot taking, and best of all: consistent shotmaking.If you are inadvertently - or intentionally - hitting up at the ball, Hit Down @#!*% ! is for you. (Also available as DVD series, and MP3 download, all on Amazon.)If you are a seasoned amateur who has inexplicably “plateaud” - just cannot seem to get to the next level despite lessons and/or acquiring a library of books and videos - Hit Down @#!*% ! is for you.Symptoms of hitting up include (but are not limited to): - topping the ball- skulling the ball- pushing the ball- slicing the ball- poor distance- difficulty getting off back foot- poor backspin- no divot- fat divots- chunking the ball- thin/fat chip shots- roofing the ball with your driver- inability to hit long irons and/or fairway woods- good shots followed immediately by poor shotsHitting down at the golf ball is not a new concept, but it is a hitherto poorly explained (or completely avoided) concept. All pros agree on the need to hit down, so there is no debate there. Even Tiger Woods, in his 306 page “How I Play Golf”, states the need to hit down at the ball – but does not explain how. Hit Down @#!*% ! does. Learn to hit down, watch the ball go up, and your scores go down.
