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.

    Then one afternoon the ground growls, hisses smoke, and swallows up his plow. A volcano is erupting in the middle of his cornfield!

    He joined a local militia during the American Revolution, rose to the rank of Major General, and became the chief aide to General George Washington. After the war, he became the first U.S. Secretary of the Treasury. He founded the Bank of New York and The New York Post newspaper. He served as a delegate to the Constitutional Convention and is also celebrated as a co-author of The Federalist Papers, a series of essays that are still used today to interpret the U.S. Constitution.The end of his life became a national scandal when he was shot and killed in a duel with then-Vice President Aaron Burr.

    Harlen Bretz walked the dry scabland channels of eastern Washington in the 1920s, it dawned on him that he was viewing a landscape sculpted by water. Lots of water. A flood of catastrophic proportions. Glacial Lake Missoula and Its Humongous Floods tells the gripping tale of a huge Ice Age lake that drained suddenly--not just once but repeatedly--and reshaped the landscape of the Northwest. The narrative follows the path of the floodwaters as they raged from western Montana across the Idaho Panhandle, then scoured through eastern Washington and down the Columbia Gorge to the Pacific Ocean. This is also the story of geologists grappling with scientific controversy--"of how personalities, pride, and prejudice sometimes superseded scientific evidence."

    She does a waggle dance, moving in a special figure-eight pattern to share the location of the foodsource with her hivemates. With vivid and active images, Rick Chrustowski brings these amazing bees to life!

    A hiker takes a refreshing drink from a mountain stream. Black-robed women in India stride gracefully through a field with brass water jugs balanced on their heads. Whether they squeeze it out of a burlap bag, haul it home from a communal tap, or get it out of their kitchen faucet, people all around the world are unified by their common need for water. Barbara Kerley brings home this point simply and eloquently in this beautiful and educational picture book that combines striking National Geographic photographs with a poetic text to show how people in various cultures use and conserve the world's most vital resource.National Geographic supports K-12 educators with ELA Common Core Resources.Visit www.natgeoed.org/commoncore for more information.From the Trade Paperback edition.

    Starting once again with fossils, he turns his gaze skyward, showing us how the entirety of the universe’s fourteen-billion-year history can be seen in our bodies. As he moves from our very molecular composition (a result of stellar events at the origin of our solar system) through the workings of our eyes, Shubin makes clear how the evolution of the cosmos has profoundly marked our own bodies. Fully illustrated with black and white drawings.

    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.

    His early life consisted of several highs and lows, from graduating high school and attending Harvard to getting laid off and losing his first wife. These experiences gave Bradley the idea for his first board game: The Checkered Game of Life. He produced and sold Life across the country and it quickly became a national sensation. Working with his company, the Milton Bradley Company, he continued to produce board games, crayons, and kid-friendly school supplies for the rest of his life. He is often credited as the father of board games, and the Milton Bradley Company has created Battleship, Jenga, Yahtzee, Trouble, and many more classic games.

    Yet this is the first book to tell the story of rain. Cynthia Barnett's  Rain begins four billion years ago with the torrents that filled the oceans, and builds to the storms of climate change. It weaves together science—the true shape of a raindrop, the mysteries of frog and fish rains—with the human story of our ambition to control rain, from ancient rain dances to the 2,203 miles of levees that attempt to straitjacket the Mississippi River. It offers a glimpse of our "founding forecaster," Thomas Jefferson, who measured every drizzle long before modern meteorology. Two centuries later, rainy skies would help inspire Morrissey’s mopes and Kurt Cobain’s grunge. Rain is also a travelogue, taking readers to Scotland to tell the surprising story of the mackintosh raincoat, and to India, where villagers extract the scent of rain from the monsoon-drenched earth and turn it into perfume. Now, after thousands of years spent praying for rain or worshiping it; burning witches at the stake to stop rain or sacrificing small children to bring it; mocking rain with irrigated agriculture and cities built in floodplains; even trying to blast rain out of the sky with mortars meant for war, humanity has finally managed to change the rain. Only not in ways we intended. As climate change upends rainfall patterns and unleashes increasingly severe storms and drought, Barnett shows rain to be a unifying force in a fractured world. Too much and not nearly enough, rain is a conversation we share, and this is a book for everyone who has ever experienced it.

    The mills at Wicksbridge are imaginary, but their planning, construction, and operation are quite typical of mills developed in New England throughout the nineteenth century.
