Most of the time this math works quietly behind the scenes . . . until it doesn't. All sorts of seemingly innocuous mathematical mistakes can have significant consequences.Math is easy to ignore until a misplaced decimal point upends the stock market, a unit conversion error causes a plane to crash, or someone divides by zero and stalls a battleship in the middle of the ocean.Exploring and explaining a litany of glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team, Matt Parker uncovers the bizarre ways math trips us up, and what this reveals about its essential place in our world. Getting it wrong has never been more fun.

    When temperatures drop below 56°F, tin crumbles into powder. Were the soldiers of the Grande Armée acutee fatally weakened by cold because the buttons of their uniforms fell apart? How different our world might be if tin did not disintegrate at low temperatures and the French had continued their eastward expansion! This fascinating book tells the stories of seventeen molecules that, like the tin of those buttons, greatly influenced the course of history. These molecules provided the impetus for early exploration and made possible the ensuing voyages of discovery. They resulted in grand feats of engineering and spurred advances in medicine; lie behind changes in gender roles, in law, and in the environment; and have determined what we today eat, drink, and wear. Showing how a change as small as the position of an atom can lead to enormous differences in the properties of a substance, the authors reveal the astonishing chemical connections among seemingly unrelated events. Napoleon's Buttons offers a novel way to understand how our contemporary world works and how our civilization has been shaped over time.

    It's harrowing, tender-hearted, and funny as hell. O'Connell proves himself to be a genius guide through all the circles of imagined and anticipated doom." --Jenny Offill By the author of the award-winning To Be a Machine, an absorbing, deeply felt book about our anxious present tense--and coming to grips with the futureWe're alive in a time of worst-case scenarios: The weather has gone uncanny. Our old postwar alliances are crumbling. Everywhere you look there's an omen, a joke whose punchline is the end of the world. How is a person supposed to live in the shadow of such a grim future? What does it mean to have children--nothing if not an act of hope? What might it be like to live through the worst? And what on Earth is anybody doing about it?Dublin-based writer Mark O'Connell is consumed by these questions--and, as the father of two young children himself, he finds them increasingly urgent. In Notes from an Apocalypse, he crosses the globe in pursuit of answers. He tours survival bunkers in South Dakota. He ventures to New Zealand, a favored retreat of billionaires banking on civilization's collapse. He engages with would-be Mars colonists, preppers, right-wing conspiracists. And he bears witness to those places, like Chernobyl, that the future has already visited--real-life portraits of the end of the world as we know it. In doing so, he comes to a resolution, while offering readers a unique window into our contemporary imagination.Both investigative and deeply personal, Notes from an Apocalypse is an affecting, humorous, and surprisingly hopeful meditation on our present moment. With insight, humanity, and wit, O'Connell leaves you to wonder: What if the end of the world isn't the end of the world?

    But if we are supposedly evolution’s greatest creation, why do we have such bad knees? Why do we catch head colds so often—two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there’s been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them.   A rollicking, deeply informative tour of humans’ four billion year long evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.

    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.

    There is no cure. In a few days 90 percent of its victims are dead. A secret military SWAT team of soldiers and scientists is mobilized to stop the outbreak of this exotic "hot" virus. The Hot Zone tells this dramatic story, giving a hair-raising account of the appearance of rare and lethal viruses and their "crashes" into the human race. Shocking, frightening, and impossible to ignore, The Hot Zone proves that truth really is scarier than fiction.

    Both the book and film were inspired by a series of multimedia presentations on global warming that Gore created and delivers to groups around the world. With this book, Gore, who is one of our environmental heroes—and a leading expert—brings together leading-edge research from top scientists around the world; photographs, charts, and other illustrations; and personal anecdotes and observations to document the fast pace and wide scope of global warming. He presents, with alarming clarity and conclusiveness—and with humor, too—that the fact of global warming is not in question and that its consequences for the world we live in will be disastrous if left unchecked. This riveting new book—written in an accessible, entertaining style—will open the eyes of even the most skeptical.

    But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

    The ice sheet that covers it is 700 miles wide and 1,500 miles long, and is composed of nearly three quadrillion tons of ice. For the last 150 years, explorers and scientists have sought to understand Greenland--at first hoping that it would serve as a gateway to the North Pole, and later coming to realize that it contained essential information about our climate. Locked within this vast and frozen white desert are some of the most profound secrets about our planet and its future. Greenland's ice doesn't just tell us where we've been. More urgently, it tells us where we're headed.In The Ice at the End of the World, Jon Gertner explains how Greenland has evolved from one of earth's last frontiers to its largest scientific laboratory. The history of Greenland's ice begins with the explorers who arrived here at the turn of the twentieth century--first on foot, then on skis, then on crude, motorized sleds--and embarked on grueling expeditions that took as long as a year and often ended in frostbitten tragedy. Their original goal was simple: to conquer Greenland's seemingly infinite interior. Yet their efforts eventually gave way to scientists who built lonely encampments out on the ice and began drilling--one mile, two miles down. Their aim was to pull up ice cores that could reveal the deepest mysteries of earth's past, going back hundreds of thousands of years.Today, scientists from all over the world are deploying every technological tool available to uncover the secrets of this frozen island before it's too late. As Greenland's ice melts and runs off into the sea, it not only threatens to affect hundreds of millions of people who live in coastal areas. It will also have drastic effects on ocean currents, weather systems, economies, and migration patterns.Gertner chronicles the unfathomable hardships, amazing discoveries, and scientific achievements of the Arctic's explorers and researchers with a transporting, deeply intelligent style--and a keen sense of what this work means for the rest of us. The melting ice sheet in Greenland is, in a way, an analog for time. It contains the past. It reflects the present. It can also tell us how much time we might have left.

    But the so-called Dark Ages also gave us the first universities, eyeglasses, and mechanical clocks, proving that the Middle Ages were home to a vibrant scientific culture.In The Light Ages, Cambridge science historian Seb Falk takes us on an immersive tour of medieval science through the story of one fourteenth-century monk, John of Westwyk. From multiplying Roman numerals to navigating by the stars, curing disease, and telling time with an ancient astrolabe, we learn emerging science alongside Westwyk, while following the gripping story of the struggles and successes of an ordinary man in a precarious world. An enlightening history that argues that these times weren’t so dark after all, The Light Ages shows how medieval ideas continue to color how we see the world today.

    Humans have "subdued 75 per cent of the land surface, concocted a wizardry of industrial and medical marvels, strung lights all across the darkness." We now collect the DNA of vanishing species in a "frozen ark," equip orangutans with iPads, create wearable technologies and synthetic species that might one day outsmart us. With her distinctive gift for making scientific discovery intelligible to the layperson, Ackerman takes us on an exciting journey to understand this bewildering new reality, introducing us to many of the people and ideas now creating--perhaps saving--the future.The Human Ageis a surprising, optimistic engagement with the dramatic transformations that have shaped, and continue to alter, our world, our relationship with nature and our prospects for the future.

    David Owen traces all that water from the Colorado's headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes readers on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the U.S.–Mexico border where the river runs dry. Water problems in the western United States can seem tantalizingly easy to solve: just turn off the fountains at the Bellagio, stop selling hay to China, ban golf, cut down the almond trees, and kill all the lawyers. But a closer look reveals a vast man-made ecosystem that is far more complex and more interesting than the headlines let on.The story Owen tells in Where the Water Goes is crucial to our future: how a patchwork of engineering marvels, byzantine legal agreements, aging infrastructure, and neighborly cooperation enables life to flourish in the desert, and the disastrous consequences we face when any part of this tenuous system fails.

    Rather, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible. For the first time, Rise of the Rocket Girls tells the stories of these women--known as "human computers"--who broke the boundaries of both gender and science. Based on extensive research and interviews with all the living members of the team, Rise of the Rocket Girls offers a unique perspective on the role of women in science: both where we've been, and the far reaches of space to which we're heading.

    Now, Haskell brings his powers of observation to the biological networks that surround all species, including humans. Haskell repeatedly visits a dozen trees around the world, exploring the trees connections with webs of fungi, bacterial communities, cooperative and destructive animals, and other plants. An Amazonian ceibo tree reveals the rich ecological turmoil of the tropical forest, along with threats from expanding oil fields. Thousands of miles away, the roots of a balsam fir in Canada survive in poor soil only with the help of fungal partners. These links are nearly two billion years old: the fir s roots cling to rocks containing fossils of the first networked cells. By unearthing charcoal left by Ice Age humans and petrified redwoods in the Rocky Mountains, Haskell shows how the Earth s climate has emerged from exchanges among trees, soil communities, and the atmosphere. Now humans have transformed these networks, powering our societies with wood, tending some forests, but destroying others. Haskell also attends to trees in places where humans seem to have subdued nature a pear tree on a Manhattan sidewalk, an olive tree in Jerusalem, a Japanese bonsai demonstrating that wildness permeates every location. Every living being is not only sustained by biological connections, but is made from these relationships. Haskell shows that this networked view of life enriches our understanding of biology, human nature, and ethics. When we listen to trees, nature s great connectors, we learn how to inhabit the relationships that give life its source, substance, and beauty."
