An exhilarating, time-traveling journey to the solar system’s strangest and most awe-inspiring volcanoes. Volcanoes are capable of acts of pyrotechnical prowess verging on magic: they spout black magma more fluid than water, create shimmering cities of glass at the bottom of the ocean and frozen lakes of lava on the moon, and can even tip entire planets over. Between lava that melts and re-forms the landscape, and noxious volcanic gases that poison the atmosphere, volcanoes have threatened life on Earth countless times in our planet’s history. Yet despite their reputation for destruction, volcanoes are inseparable from the creation of our planet. A lively and utterly fascinating guide to these geologic wonders, Super Volcanoes revels in the incomparable power of volcanic eruptions past and present, Earthbound and otherwise―and recounts the daring and sometimes death-defying careers of the scientists who study them. Science journalist and volcanologist Robin George Andrews explores how these eruptions reveal secrets about the worlds to which they belong, describing the stunning ways in which volcanoes can sculpt the sea, land, and sky, and even influence the machinery that makes or breaks the existence of life. Walking us through the mechanics of some of the most infamous eruptions on Earth, Andrews outlines what we know about how volcanoes form, erupt, and evolve, as well as what scientists are still trying to puzzle out. How can we better predict when a deadly eruption will occur―and protect communities in the danger zone? Is Earth’s system of plate tectonics, unique in the solar system, the best way to forge a planet that supports life? And if life can survive and even thrive in Earth’s extreme volcanic environments―superhot, superacidic, and supersaline surroundings previously thought to be completely inhospitable―where else in the universe might we find it? Traveling from Hawai‘i, Yellowstone, Tanzania, and the ocean floor to the moon, Venus, and Mars, Andrews illuminates the cutting-edge discoveries and lingering scientific mysteries surrounding these phenomenal forces of nature. 10 illustrations

One of the first maps of Mars, published by an Italian astronomer in 1877, with its pattern of canals, fueled belief in intelligent life forms on the distant red planet—a hope that continued into the 1960s. Although the Martian canals have long since been dismissed as a famous error in the history of science, K. Maria D. Lane argues that there was nothing accidental about these early interpretations. Indeed, she argues, the construction of Mars as an incomprehensibly complex and engineered world both reflected and challenged dominant geopolitical themes during a time of major cultural, intellectual, political, and economic transition in the Western world. Geographies of Mars telescopes in on a critical period in the development of the geographical imagination, when European imperialism was at its zenith and American expansionism had begun in earnest. Astronomers working in the new observatories of the American Southwest or in the remote heights of the South American Andes were inspired, Lane finds, by their own physical surroundings and used representations of the Earth’s arid landscapes to establish credibility for their observations of Mars. With this simple shift to the geographer’s point of view, Lane deftly explains some of the most perplexing stances on Mars taken by familiar protagonists such as Percival Lowell, Alfred Russel Wallace, and Lester Frank Ward. A highly original exploration of geography’s spatial dimensions at the beginning of the twentieth century, Geographies of Mars offers a new view of the mapping of far-off worlds.

NATIONAL BESTSELLER • A deeply engaging history of how European settlements in the post-Colombian Americas shaped the world—from the highly acclaimed author of 1491. • "Fascinating...Lively...A convincing explanation of why our world is the way it is." —The New York Times Book Review Presenting the latest research by biologists, anthropologists, archaeologists, and historians, Mann shows how the post-Columbian network of ecological and economic exchange fostered the rise of Europe, devastated imperial China, convulsed Africa, and for two centuries made Mexico City—where Asia, Europe, and the new frontier of the Americas dynamically interacted—the center of the world. In this history, Mann uncovers the germ of today's fiercest political disputes, from immigration to trade policy to culture wars. In 1493, Mann has again given readers an eye-opening scientific interpretation of our past, unequaled in its authority and fascination.

A stunning and provocative new novel by the internationally celebrated author of The Blind Assassin, winner of the Booker Prize Margaret Atwood’s new novel is so utterly compelling, so prescient, so relevant, so terrifyingly-all-too-likely-to-be-true, that readers may find their view of the world forever changed after reading it. This is Margaret Atwood at the absolute peak of her powers. For readers of Oryx and Crake, nothing will ever look the same again. The narrator of Atwood's riveting novel calls himself Snowman. When the story opens, he is sleeping in a tree, wearing an old bedsheet, mourning the loss of his beloved Oryx and his best friend Crake, and slowly starving to death. He searches for supplies in a wasteland where insects proliferate and pigoons and wolvogs ravage the pleeblands, where ordinary people once lived, and the Compounds that sheltered the extraordinary. As he tries to piece together what has taken place, the narrative shifts to decades earlier. How did everything fall apart so quickly? Why is he left with nothing but his haunting memories? Alone except for the green-eyed Children of Crake, who think of him as a kind of monster, he explores the answers to these questions in the double journey he takes - into his own past, and back to Crake's high-tech bubble-dome, where the Paradice Project unfolded and the world came to grief. With breathtaking command of her shocking material, and with her customary sharp wit and dark humour, Atwood projects us into an outlandish yet wholly believable realm populated by characters who will continue to inhabit our dreams long after the last chapter. This is Margaret Atwood at the absolute peak of her powers.
