It is within the realm of possibility that their work may usher in a change in global economics as profound as the Industrial Revolution. As may be expected, press reports dealing with asteroid mining have been numerous, ranging in scope from short and breezy to broad and serious, and in quality from accurate to impressionistic to simply uninformed. There is good reason to be curious about what may be the biggest game-changer in human economic history. And there is good reason to look closely at the underlying science and engineering that form the foundation of this work.

    McPhee embarks on a fascinating journey across the basement of the continent -- the land masses forming Illinois, Iowa, Nebraska, and thereabouts -- with a professor and geochronologist acting as a guide.

    At present, Lake Powell is less than half full. Bathtub rings ten stories tall encircle its blue water; boat ramps and marinas lie stranded and useless. To refill it would require surplus water—but there is no surplus: burgeoning populations and thirsty crops consume every drop of the Colorado River. Add to this picture the looming effects of global warming and drought, and the scenario becomes bleaker still. Dead Pool, featuring rarely seen historical photographs, explains why America built the dam that made Lake Powell and others like it and then allowed its citizens to become dependent on their benefits, which were always temporary. Writing for a wide audience, Powell shows us exactly why an urgent threat during the first half of the twenty-first century will come not from the rising of the seas but from the falling of the reservoirs.

    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.

    Half a century later, only robots have been to the Red Planet and our astronauts rarely venture beyond Earth orbit.Now Mars is back With everyone from Elon Musk to Ridley Scott and Donald Trump talking about it, interplanetary exploration is back on the agenda and Mars is once again the prime destination for future human expansion and colonisation. In Destination Mars, astrophysicist and science writer Andrew May traces the history of our fascination with the Red Planet and explores the science upon which a crewed mission would be based, from assembling a spacecraft in Earth orbit to surviving solar storms. With expert insight, he analyses the new space race and assesses what the future holds for human life on Mars.

    If today you’ve listened to recorded music, watched a television show or movie, plugged something into an electric socket, had an X-ray, turned on your car, spoke on the telephone, or flicked on an electric light, you have Edison to thank for his pioneering work in these fields, and many more. Yet Edison is all too often remembered in popular culture only as villain for his feuds with other inventors, most notably the mad genius Nikola Tesla. In this thrilling, compact biography, Alexander Kennedy sorts fact from fiction in the life of the most prolific inventor in human history. We follow Edison, the ultimate self-made man, from his origins as a Michigan telegraph boy to the pinnacle of success as an industrial titan. Along the way, Kennedy carefully explains each of Edison’s key breakthroughs as well as the blots on his record, such as his anti-Semitism and his unhappy family life. The portrait that emerges is a man who is neither hero nor villain, sometimes a saint and sometimes a sinner—but always a genius...

    Titan Unveiled is one of the first general interest books to reveal the startling new discoveries that have been made since the arrival of the Cassini-Huygens mission to Saturn and Titan.Ralph Lorenz and Jacqueline Mitton take readers behind the scenes of this mission. Launched in 1997, Cassini entered orbit around Saturn in summer 2004. Its formidable payload included the Huygens probe, which successfully parachuted down through Titan's atmosphere in early 2005, all the while transmitting images and data--and scientists were startled by what they saw. One of those researchers was Lorenz, who gives an insider's account of the scientific community's first close encounter with an alien landscape of liquid methane seas and turbulent orange skies. Amid the challenges and frayed nerves, new discoveries are made, including methane monsoons, equatorial sand seas, and Titan's polar hood. Lorenz and Mitton describe Titan as a world strikingly like Earth and tell how Titan may hold clues to the origins of life on our own planet and possibly to its presence on others.Generously illustrated with many stunning images, Titan Unveiled is essential reading for anyone interested in space exploration, planetary science, or astronomy.-- "Lunar and Planetary Information Bulletin"

    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.

    Known for its complete coverage of concepts and principles along with a more systematic and descriptive treatment of mineralogy, the revised edition now includes a CD-ROM to let readers see the minerals and crystals, while also viewing chemical composition, symmetry, and morphological crystallography.

    Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. From Egypt's pyramids to the Hubble telescope, from the world's tallest skyscraper to the sidewalk below it, from Chartres' stained-glass windows to your iPhone, sand shelters us, empowers us, engages us, and inspires us. It's the ingredient that makes possible our cities, our science, our lives--and our future.And, incredibly, we're running out of it.The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it--and sometimes, even kill for it. It's also a provocative examination of the serious human and environmental costs incurred by our dependence on sand, which has received little public attention. Not all sand is created equal: Some of the easiest sand to get to is the least useful. Award-winning journalist Vince Beiser delves deep into this world, taking readers on a journey across the globe, from the United States to remote corners of India, China, and Dubai to explain why sand is so crucial to modern life. Along the way, readers encounter world-changing innovators, island-building entrepreneurs, desert fighters, and murderous sand pirates. The result is an entertaining and eye-opening work, one that is both unexpected and involving, rippling with fascinating detail and filled with surprising characters.

    The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society.This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.

    Alvarez had the first glimmer of that amazing insight when he noticed something odd in a rock outcrop in central Italy. Alvarez now returns to that rich terrain, this time to take the reader on an excavation of the Earth's distant past. We encounter the volcanoes that formed the Seven Hills of Rome; the majestic limestone Apennine mountains that started to develop millions of years ago under water; the evidence that the Mediterranean Sea completely evaporated to a sunken desert, perhaps several times; and the proof that continental plates once overran one another to form the Alps. In Alvarez's telling, all major geologic episodes are as dramatic as the great impact that killed the dinosaurs, even when they happen over eons and without huge creatures to witness them.

    Hazen writes of how the co-evolution of the geosphere and biosphere—of rocks and living matter—has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.With an astrobiologist’s imagination, a historian’s perspective, and a naturalist’s passion for the ground beneath our feet, Hazen explains how changes on an atomic level translate into dramatic shifts in Earth’s makeup over its 4.567 billion year existence. He calls upon a flurry of recent discoveries to portray our planet’s many iterations in vivid detail. Through his theory of “co-evolution,” we learn how reactions between organic molecules and rock crystals may have generated Earth’s first organisms, which in turn are responsible for more than two-thirds of the mineral varieties on the planet.The Story of Earth is also the story of the pioneering men and women behind the sciences. Readers will meet black-market meteorite hawkers of the Sahara Desert, the gun-toting Feds who guarded the Apollo missions’ lunar dust, and the World War II Navy officer whose super-pressurized “bomb”—recycled from military hardware—first simulated the molten rock of Earth’s mantle. As a mentor to a new generation of scientists, Hazen introduces the intrepid young explorers whose dispatches from Earth’s harshest landscapes will revolutionize geology.

    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.

    Although Australia’s prompt, science-led response to COVID-19 has not been perfect, it has saved tens of thousands of lives. But for decades, governments have ignored, ridiculed or understated the advice of scientists on the climate emergency.Now, in the wake of the megafires of 2020, a time of reckoning has arrived. In The Climate Cure renowned climate scientist Tim Flannery takes aim at those responsible for the campaign of obfuscation and denial that has already cost so many Australian lives and held back action on climate change.Flannery demands a new approach, based on the nation’s response to COVID-19, that will lead to effective government policies. The Climate Cure is an action plan for our future. We face a fork in the road, and must decide now between catastrophe and survival.
