Radiometric dating of nearby rocks indicated the skeleton, classified as Ardipithecus ramidus, was 4.4 million years old, more than a million years older than "Lucy," then the oldest known human ancestor. The findings challenged many assumptions about human evolution--how we started walking upright, how we evolved our nimble hands, and, most significantly, whether we were descended from an ancestor that resembled today's chimpanzee--and repudiated a half-century of paleoanthropological orthodoxy.Fossil Men is the first full-length exploration of Ardi, the fossil men who found her, and her impact on what we know about the origins of the human species. It is a scientific detective story played out in anatomy and the natural history of the human body. Kermit Pattison brings into focus a cast of eccentric, obsessive scientists, including one of the world's greatest fossil hunters, Tim White--an exacting and unforgiving fossil hunter whose virtuoso skills in the field were matched only by his propensity for making enemies; Gen Suwa, a Japanese savant who sometimes didn't bother going home at night to devote more hours to science; Owen Lovejoy, a onetime creationist-turned-paleoanthropologist; Berhane Asfaw, who survived imprisonment and torture to become Ethiopia's most senior paleoanthropologist and who fought for African scientists to gain equal footing in the study of human origins; and the Leakeys, for decades the most famous family in paloanthropology.An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa and a nation caught in a brutal civil war, to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must read for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.

    And this updated edition contains a host of new findings on “Gemstones for Collectors,” additional gems in the “Table of Constants,” and the “double fraction” figures that experts have long wanted—a very special new feature.All the gemstones are treated in their many variations: more than 1,500 full-color photos showcase each precious and semiprecious stone in both its rough, natural, and its polished and cut renditions. Each entry offers complete information on the gemstone’s formation, structure, physical properties, and characteristics, along with the best methods of working, cutting, and polishing it. There are even full treatments of lesser-known gems, from andalusite to vesuvian, and a special section is devoted to rocks as precious stones, including alabaster, onyx, obsidian, and fossils. Organic gem materials are also covered, such as coral, ivory, amber, and pearl. Charts and tables help collectors identify unknown gemstones and check for genuineness.

    Told by a geologist with a novelist's sense of language and narrative, Sand examines the science—sand forensics, the physics of granular materials, sedimentology, paleontology and archaeology, planetary exploration—and at the same time explores the rich human context of sand. Interwoven with tales of artists, mathematicians, explorers, and even a vampire, the story of sand is an epic of environmental construction and destruction, an adventure in staggering scales of time and distance, yet a tale that encompasses the ordinary and everyday. Sand, in fact, is all around us—it has made possible our computers, buildings and windows, toothpaste, cosmetics, and paper, and it has played dramatic roles in human history, commerce, and imagination. In this luminous, kinetic, revelatory account, we do indeed find the world in a grain of sand.

    The only question is when. In the meantime, we need to get much better at finding objects hurtling our way, and if they’re large enough to penetrate the atmosphere without burning up, figure out what to do about them. We owe many of science’s most important discoveries to the famed Meteor Crater, a mile-wide dimple on the Colorado Plateau created by an asteroid hit 50,000 years ago. In his masterfully researched Fire in the Sky, Dillow unpacks what the Crater has to tell us. Prior to the early 1900s, the world believed that all craters—on the Earth and Moon—were formed by volcanic activity. Not so. The revelation that Meteor Crater and others like it were formed by impacts with space objects has led to a now accepted theory about what killed off the dinosaurs, and it has opened up a new field of asteroid observation, which has recently brimmed with urgency. Dillow looks at great asteroid hits of the past and spends time with modern-day asteroid hunters and defense planning experts, including America’s first Planetary Defense Officer. Satellite sensors confirm that a Hiroshima-scale blast occurs in the atmosphere every year, and a smaller, one-kiloton blast every month. While Dillow makes clear that the objects above can be deadly, he consistently inspires awe with his descriptions of their size, makeup, and origins. At once a riveting work of popular science and a warning to not take for granted the space objects hurtling overhead, Fire in the Sky is, above all, a testament to our universe’s celestial wonders.

    In 1969 we even walked on the moon. And yet as late as 2000, the earth’s deepest cave—the supercave—remained undiscovered. This is the story of the men and women who risked everything to find it, earning their place in history beside the likes of Peary, Amundsen, Hillary, and Armstrong. In 2004, two great scientist-explorers are attempting to find the bottom of the world. Bold, heroic American Bill Stone is committed to the vast Cheve Cave, located in southern Mexico and deadly even by supercave standards. On the other side of the globe, legendary Ukrainian explorer Alexander Klimchouk—Stone’s polar opposite in temperament and style, but every bit his equal in scientific expertise, physical bravery, and sheer determination—has targeted Krubera, a freezing nightmare of a supercave in the Republic of Georgia, where underground dangers are compounded by the horrors of separatist war in this former Soviet republic.

    Now palaeontologist Charles Pellegrino presents a wealth of new knowledge about the doomed towns – and brings to vivid life the people, their last moments, and the aftermath.The lessons learned from modern scrutiny of that ancient eruption produce disturbing echoes in the present. Dr Pellegrino, who worked at Ground Zero in the aftermath of the 9/11 attack, shares his unique knowledge of the strange physics of volcanic 'downblast' and 'collapse column', drawing a direct link from past to present, and providing readers with a poignant glimpse into the last moments of the 'American Vesuvius'.

    In 1993, at Volcán Galeras, the death toll was smaller but no less tragic: despite seismic data that foretold possible disaster, an expedition of international scientists proceeded into the volcano. Two hours later, nine people were dead.Expertly detailing the turbulent history of Colombia, Victoria Bruce links together the stories of the heroes, villains, survivors, and victims of these two events. No Apparent Danger is a spellbinding account of clashing cultures and the life-and-death consequences of scientific arrogance.

    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.

    Yet the man behind what became "America's attic," James Smithson, has remained a shadowy figure for more than 150 years.Drawing on unpublished diaries and letters from across Europe and the United States, historian Heather Ewing tells his compelling story in full. The illegitimate son of the Duke of Northumberland, Smithson was the youngest member of Britain's Royal Society and a talented chemist admired by the greatest scientists of his age. At the same time, however, he was also a suspected spy, an inveterate gambler, and a radical revolutionary during the turbulent years of the Napoleonic Wars. But at the heart of Smithson's story is his bequest—worth $9 million in today in today's currency—which sparked an international lawsuit and a decade-long congressional battle, featuring a dizzying cast of historical figures, including John Quincy Adams, and Alexander Graham Bell, both of whom grappled with how—and even whether—to put Smithson's endowment to use.Fascinating and magisterial, Ewing's biography presents a sweeping portrait of a remarkable man at the center of the English Enlightenment and the creation of America's greatest museum.

    Either way, we can listen to nearly anything, at any time. The possibilities in this new age of listening overturn old assumptions about what it means to properly appreciate music—to be an “educated” listener. In Every Song Ever, the veteran New York Times music critic Ben Ratliff reimagines the very idea of music appreciation for our times. As familiar subdivisions like “rock” and “jazz” matter less and less and music’s accessible past becomes longer and broader, listeners can put aside the intentions of composers and musicians and engage music afresh, on their own terms. Ratliff isolates signal musical traits—such as repetition, speed, and virtuosity—and traces them across wildly diverse recordings to reveal unexpected connections. When we listen for slowness, for instance, we may detect surprising affinities between the drone metal of Sunn O))), the mixtape manipulations of DJ Screw, Sarah Vaughan singing “Lover Man,” and the final works of Shostakovich. And if we listen for closeness, we might notice how the tight harmonies of bluegrass vocals illuminate the virtuosic synchrony of John Coltrane’s quartet. Ratliff also goes in search of “the perfect moment”; considers what it means to hear emotion by sampling the complex sadness that powers the music of Nick Drake and Slayer; and examines the meaning of certain common behaviors, such as the impulse to document and possess the entire performance history of the Grateful Dead. Encompassing the sounds of five continents and several centuries, Ratliff’s book is an artful work of criticism and a lesson in open-mindedness. It is a definitive field guide to our radically altered musical habitat.
