Who invented zero? Why are there 60 seconds in a minute? Can a butterfly's wings really cause a storm on the far side of the world? In 50 concise essays, Professor Tony Crilly explains the mathematical concepts that allow use to understand and shape the world around us.

    The author argues for the preservation of the time and space in which to walk in an ever more car-dependent and accelerated world.

    Each of us, too, is a landscape inscribed by memory and loss. One life-defining lesson Lauret Savoy learned as a young girl was this: the American land did not hate. As an educator and Earth historian, she has tracked the continent’s past from the relics of deep time; but the paths of ancestors toward her—paths of free and enslaved Africans, colonists from Europe, and peoples indigenous to this land—lie largely eroded and lost.In this provocative and powerful mosaic of personal journeys and historical inquiry across a continent and time, Savoy explores how the country’s still unfolding history, and ideas of “race,” have marked her and the land. From twisted terrain within the San Andreas Fault zone to a South Carolina plantation, from national parks to burial grounds, from “Indian Territory” and the U.S.-Mexico Border to the U.S. capital, Trace grapples with a searing national history to reveal the often unvoiced presence of the past.In distinctive and illuminating prose that is attentive to the rhythms of language and landscapes, she weaves together human stories of migration, silence, and displacement, as epic as the continent they survey, with uplifted mountains, braided streams, and eroded canyons.

Yet, we love them still.Content:Catacombs Cat's cradle What's the catch? The cats that ate the canaries The cat lobby CAT scan Pandora's litter box Lions and toygers and lykoi Nine likes.

    In the past, discoveries often had to wait for the rise of the next generation to see questions in a new light and let go of old truisms. Today, in a world that is defined by a rapid rate of change, staying on the cutting edge has as much to do with shedding outdated notions as adopting new ones. In this spirit, John Brockman, publisher of the online salon Edge.org ("the world's smartest website"—The Guardian), asked 175 of the world's most influential scientists, economists, artists, and philosophers: What scientific idea is ready for retirement?Jared Diamond explores the diverse ways that new ideas emerge * Nassim Nicholas Taleb takes down the standard deviation * Richard Thaler and novelist Ian McEwan reveal the usefulness of "bad" ideas * Steven Pinker dismantles the working theory of human behavior * Richard Dawkins renounces essentialism * Sherry Turkle reevaluates our expectations of artificial intelligence * Physicist Andrei Linde suggests that our universe and its laws may not be as unique as we think * Martin Rees explains why scientific understanding is a limitless goal * Alan Guth rethinks the origins of the universe * Sam Harris argues that our definition of science is too narrow * Nobel Prize winner Frank Wilczek disputes the division between mind and matter * Lawrence Krauss challenges the notion that the laws of physics were preordained * plus contributions from Daniel Goleman, Mihaly Csikszentmihalyi, Nicholas Carr, Rebecca Newberger Goldstein, Matt Ridley, Stewart Brand, Sean Carroll, Daniel C. Dennett, Helen Fisher, Douglas Rushkoff, Lee Smolin, Kevin Kelly, Freeman Dyson, and others.

    Mapped by John Smith in 1608, settled during the American Revolution, the tiny sliver of mud is home to 470 hardy people who live an isolated and challenging existence, with one foot in the 21st century and another in times long passed. They are separated from their countrymen by the nation’s largest estuary, and a twelve-mile boat trip across often tempestuous water—the same water that for generations has made Tangier’s fleet of small fishing boats a chief source for the rightly prized Chesapeake Bay blue crab, and has lent the island its claim to fame as the softshell crab capital of the world.Yet for all of its long history, and despite its tenacity, Tangier is disappearing. The very water that has long sustained it is erasing the island day by day, wave by wave. It has lost two-thirds of its land since 1850, and still its shoreline retreats by fifteen feet a year—meaning this storied place will likely succumb first among U.S. towns to the effects of climate change. Experts reckon that, barring heroic intervention by the federal government, islanders could be forced to abandon their home within twenty-five years. Meanwhile, the graves of their forebears are being sprung open by encroaching tides, and the conservative and deeply religious Tangiermen ponder the end times.Chesapeake Requiem is an intimate look at the island’s past, present and tenuous future, by an acclaimed journalist who spent much of the past two years living among Tangier’s people, crabbing and oystering with its watermen, and observing its long traditions and odd ways. What emerges is the poignant tale of a world that has, quite nearly, gone by—and a leading-edge report on the coming fate of countless coastal communities.

    Making use of remarkable scientific discoveries that transform our understanding of how natural systems work, George Monbiot explores a new, positive environmentalism that shows how damaged ecosystems on land and at sea can be restored, and how this restoration can revitalize and enrich our lives. Challenging what he calls his “ecological boredom,” Monbiot weaves together a beautiful and riveting tale of wild places, wildlife, and wild people. Roaming the hills of Britain and the forests of Europe, kayaking off the coast of Wales with dolphins and seabirds, he seeks out the places that still possess something of the untamed spirit he would like to resurrect.He meets people trying to restore lost forests and bring back missing species—such as wolves, lynx, wolverines, wild boar, and gray whales—and explores astonishing evidence that certain species, not just humans, have the power to shape the physical landscape. This process of rewilding, Monbiot argues, offers an alternative to a silent spring: the chance of a raucous summer in which ecological processes resume and humans draw closer to the natural world.

    There are Douglas firs as tall as skyscrapers, and a banyan tree in Calcutta as big as a football field.From the tallest to the smallest, trees inspire wonder in all of us, and in The Tree, Colin Tudge travels around the world—throughout the United States, the Costa Rican rain forest, Panama and Brazil, India, New Zealand, China, and most of Europe—bringing to life stories and facts about the trees around us: how they grow old, how they eat and reproduce, how they talk to one another (and they do), and why they came to exist in the first place. He considers the pitfalls of being tall; the things that trees produce, from nuts and rubber to wood; and even the complicated debt that we as humans owe them.Tudge takes us to the Amazon in flood, when the water is deep enough to submerge the forest entirely and fish feed on fruit while river dolphins race through the canopy. He explains the “memory” of a tree: how those that have been shaken by wind grow thicker and sturdier, while those attacked by pests grow smaller leaves the following year; and reveals how it is that the same trees found in the United States are also native to China (but not Europe).From tiny saplings to centuries-old redwoods and desert palms, from the backyards of the American heartland to the rain forests of the Amazon and the bamboo forests, Colin Tudge takes the reader on a journey through history and illuminates our ever-present but often ignored companions. A blend of history, science, philosophy, and environmentalism, The Tree is an engaging and elegant look at the life of the tree and what modern research tells us about their future.

    Before humans ruled the earth, there were wolves. Once abundant in North America, these majestic creatures were hunted to near extinction in the lower 48 states by the 1920s. But in recent decades, conservationists have brought wolves back to the Rockies, igniting a battle over the very soul of the West.With novelistic detail, Nate Blakeslee tells the gripping story of one of these wolves, O-Six, a charismatic alpha female named for the year of her birth. Uncommonly powerful, with gray fur and faint black ovals around each eye, O-Six is a kind and merciful leader, a fiercely intelligent fighter, and a doting mother. She is beloved by wolf watchers, particularly renowned naturalist Rick McIntyre, and becomes something of a social media star, with followers around the world.But as she raises her pups and protects her pack, O-Six is challenged on all fronts: by hunters, who compete with wolves for the elk they both prize; by cattle ranchers who are losing livestock and have the ear of politicians; and by other Yellowstone wolves who are vying for control of the park’s stunningly beautiful Lamar Valley.These forces collide in American Wolf, a riveting multi-generational saga of hardship and triumph that tells a larger story about the ongoing cultural clash in the West—between those fighting for a vanishing way of life and those committed to restoring one of the country’s most iconic landscapes.

    Vesuvius, whose eruption in Roman times helped spark the science of geology, and ending in a lab in the West of England where mathematical models and lab experiments replace direct observation, Richard Fortey tells us what the present says about ancient geologic processes. He shows how plate tectonics came to rule the geophysical landscape and how the evidence is written in the hills and in the stones. And in the process, he takes us on a wonderful journey around the globe to visit some of the most fascinating and intriguing spots on the planet.

    In this narrative, readers experience The Great Hurricane of 1938, the most financially destructive storm on record.

    Keenly aware that the course of the nation's destiny lay westward—and that a "Voyage of Discovery" would be necessary to determine the nature of the frontier—President Thomas Jefferson commissioned Meriwether Lewis to lead an expedition from the Missouri River to the northern Pacific coast and back. From 1804 to 1806, accompanied by co-captain William Clark, the Shoshone guide Sacajawea, and thirty-two men, Lewis mapped rivers, traced the principal waterways to the sea, and established the American claim to the territories of Idaho, Washington, and Oregon. Together the captains kept this journal: a richly detailed record of the flora and fauna they sighted, the native tribes they encountered, and the awe-inspiring landscape they traversed, from their base camp near present-day St. Louis to the mouth of the Columbia River, that has become an incomparable contribution to the literature of exploration and the writing of natural history.

    A bold foray into the heart of the American West’s final frontier, the expedition was achieved without benefit of modern river-running equipment, supplies, or a firm sense of the region’s perilous topography and the attitudes of the native inhabitants towards whites.For more than seventy years, Penguin has been the leading publisher of classic literature in the English-speaking world.
