In the book, Sagan explores 15 billion years of cosmic evolution and the development of science and civilization. Cosmos traces the origins of knowledge and the scientific method, mixing science and philosophy, and speculates to the future of science. The book also discusses the underlying premises of science by providing biographical anecdotes about many prominent scientists throughout history, placing their contributions into the broader context of the development of modern science.The book covers a broad range of topics, comprising Sagan's reflections on anthropological, cosmological, biological, historical, and astronomical matters from antiquity to contemporary times. Sagan reiterates his position on extraterrestrial life—that the magnitude of the universe permits the existence of thousands of alien civilizations, but no credible evidence exists to demonstrate that such life has ever visited earth.

    More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond.Nothing like this has occurred in a generation--a raw exploration of new worlds unparalleled since NASA's Voyager missions to Uranus and Neptune--and nothing like it is planned to happen ever again. The photos that New Horizons sent back to Earth graced the front pages of newspapers on all 7 continents, and NASA's website for the mission received more than 2 billion hits in the days surrounding the flyby. At a time when so many think our most historic achievements are in the past, the most distant planetary exploration ever attempted not only succeeded but made history and captured the world's imagination.How did this happen? Chasing New Horizons is the story of the men and women behind the mission: of their decades-long commitment; of the political fights within and outside of NASA; of the sheer human ingenuity it took to design, build, and fly the mission; and of the plans for New Horizons' next encounter, 1 billion miles past Pluto. Told from the insider's perspective of Dr. Alan Stern--the man who led the mission--Chasing New Horizons is a riveting story of scientific discovery, and of how far humanity can go when people focused on a dream work together toward their incredible goal.

    But in this thought-provoking collection, twenty-eight writers and scholars give engaging, often passionate accounts of their own nation’s history. The countries have been selected to represent every continent and every type of state: large and small; mature democracies and religious autocracies; states that have existed for thousands of years and those born as recently as the twentieth century. Together they contain two-thirds of the world’s population. In the United States, for example, the myth of the nation’s “historylessness” remains strong, but in China history is seen to play a crucial role in legitimizing three thousand years of imperial authority. “History wars” over the content of textbooks rage in countries as diverse as Australia, Russia, and Japan. Some countries, such as Iran or Egypt, are blessed—or cursed—with a glorious ancient history that the present cannot equal; others, such as Germany, must find ways of approaching and reconciling the pain of the recent past.

    A team of journalists with unparalleled inside access provides the first full, in-depth account of WikiLeaks, its founder Julian Assange, and the ethical, legal, and political controversies it has both uncovered and provoked.

    How they got here, persevered, and ultimately thrived is a story that resonates from the Pleistocene to our modern era. The lower sea levels of the Ice Age exposed a vast land bridge between Asia and North America, but the land bridge was not the only way across. Different people arrived from different directions, and not all at the same time.The first explorers of the New World were few, their encampments fleeting. The continent they reached had no people but was inhabited by megafauna--mastodons, giant bears, mammoths, saber-toothed cats, five-hundred-pound panthers, enormous bison, and sloths that stood one story tall. The first people were hunters--Paleolithic spear points are still encrusted with the proteins of their prey--but they were wildly outnumbered and many would themselves have been prey to the much larger animals.Atlas of a Lost World chronicles the last millennia of the Ice Age, the violent oscillations and retreat of glaciers, the clues and traces that document the first encounters of early humans, and the animals whose presence governed the humans' chances for survival. A blend of science and personal narrative reveals how much has changed since the time of mammoth hunters, and how little. Across unexplored landscapes yet to be peopled, readers will see the Ice Age, and their own age, in a whole new light.

    Now he makes the case that living on Mars is not just plausible, but inevitable.It sounds like science fiction, but Stephen Petranek considers it fact: Within twenty years, humans will live on Mars. We'll need to. In this sweeping, provocative book that mixes business, science, and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity and explains in fascinating detail just how it will happen.The race is on. Private companies, driven by iconoclastic entrepreneurs, such as Elon Musk, Jeff Bezos, Paul Allen, and Sir Richard Branson; Dutch reality show and space mission Mars One; NASA; and the Chinese government are among the many groups competing to plant the first stake on Mars and open the door for human habitation. Why go to Mars? Life on Mars has potential life-saving possibilities for everyone on earth. Depleting water supplies, overwhelming climate change, and a host of other disasters — from terrorist attacks to meteor strikes — all loom large. We must become a space-faring species to survive. We have the technology not only to get humans to Mars, but to convert Mars into another habitable planet. It will likely take 300 years to "terraform" Mars, as the jargon goes, but we can turn it into a veritable second Garden of Eden. And we can live there, in specially designed habitations, within the next twenty years.In this exciting chronicle, Petranek introduces the circus of lively characters all engaged in a dramatic effort to be the first to settle the Red Planet. How We'll Live on Mars brings firsthand reporting, interviews with key participants, and extensive research to bear on the question of how we can expect to see life on Mars within the next twenty years.

    The desire to own the skulls of the famous, for study, for sale, for public (and private) display, seems to be instinctual and irresistible in some people. The rise of phrenology at the beginning of the 19th century only fed that fascination with the belief that genius leaves its mark on the very shape of the head.

    Since the first thread was spun, the need for textiles has driven technology, business, politics, and culture.In The Fabric of Civilization, Virginia Postrel synthesizes groundbreaking research from archaeology, economics, and science to reveal a surprising history. From Minoans exporting wool colored with precious purple dye to Egypt, to Romans arrayed in costly Chinese silk, the cloth trade paved the crossroads of the ancient world. Textiles funded the Renaissance and the Mughal Empire; they gave us banks and bookkeeping, Michelangelo's David and the Taj Mahal. The cloth business spread the alphabet and arithmetic, propelled chemical research, and taught people to think in binary code.Assiduously researched and deftly narrated, The Fabric of Civilization tells the story of the world's most influential commodity.

    Shubin describes how over the last half-century, scientists have been able to explore how genetic recipes build bodies during embryological development--how these inventions and adaptations occur in a nonprogressive manner in different contexts, at different speeds. Paleontology has been transformed over the last 50 years by tools and techniques of molecular biology--and it is that revolution in our understanding of the evolution of life that Shubin traces here. Each of us is a mosaic of precursors that came about at different times and places, with deep rooted connections across species that Darwin, for all he understood, could never even have imagined.

    • Mercury thermometers are prohibited on airplanes for a crucial reason.• Kryptonite bicycle locks are easily broken.“Things fall apart” is more than a poetic insight—it is a fundamental property of the physical world. Why Things Break explores the fascinating question of what holds things together (for a while), what breaks them apart, and why the answers have a direct bearing on our everyday lives.When Mark Eberhart was growing up in the 1960s, he learned that splitting an atom leads to a terrible explosion—which prompted him to worry that when he cut into a stick of butter, he would inadvertently unleash a nuclear cataclysm. Years later, as a chemistry professor, he remembered this childhood fear when he began to ponder the fact that we know more about how to split an atom than we do about how a pane of glass breaks.In Why Things Break, Eberhart leads us on a remarkable and entertaining exploration of all the cracks, clefts, fissures, and faults examined in the field of materials science and the many astonishing discoveries that have been made about everything from the explosion of the space shuttle Challenger to the crashing of your hard drive. Understanding why things break is crucial to modern life on every level, from personal safety to macroeconomics, but as Eberhart reveals here, it is also an area of cutting-edge science that is as provocative as it is illuminating.“An engaging personal account not just of the physics and chemistry of materials but of the ethics, economics, and politics of innovation, with delightful bonuses on topics from the origins of ‘ghostly’ noises in old houses to the amazing coevolution of armor and armor-piercing projectiles. If it ain’t broke, Mark Eberhart can tell you why—and explain equally well why a shatterproof world remains beyond our reach.”—Edward Tenner, author of Our Own Devices and Why Things Bite Back“I don’t remember a book that has taught me so much, nor previously encountering a teacher like the marvelous Mark Eberhart, who in Why Things Break provides enlightening and thoroughly captivating scientific explanations of subjects ranging from the structural failures leading to the sinking of the Titanic to everyday, no-less-fascinating topics such as the reason why, even at the same temperature, winter days always seem so much colder in Boston than in Denver.”—Richard Restak, M.D., author of Mozart’s Brain and The Fighter Pilot“Eberhart brings his insights to the reader by weaving personal anecdotes—from his childhood fear that cutting a stick of butter would release the energy of the atoms within to his arrival in Boston for an interview with MIT without a suitable winter coat—into a fascinating discussion of the forces that hold atoms and molecules together. A lively, unvarnished look at chemistry on the cutting edge.” —Kirkus Reviews

    But this attitude is a relatively recent development in the sweep of history. In The Pun Also Rises, John Pollack — a former Presidential Speechwriter for Bill Clinton, and winner of the world pun championship — explains how punning revolutionized language and made possible the rise of modern civilization. Integrating evidence from history, pop culture, literature, comedy, science, business and everyday life, this book will make readers reconsider everything they think they know about puns.

    Or is it? John Reader’s narrative on the role of the potato in world history suggests we may be underestimating this remarkable tuber. From domestication in Peru 8,000 years ago to its status today as the world’s fourth largest food crop, the potato has played a starring—or at least supporting—role in many chapters of human history. In this witty and engaging book, Reader opens our eyes to the power of the potato.Whether embraced as the solution to hunger or wielded as a weapon of exploitation, blamed for famine and death or recognized for spurring progress, the potato has often changed the course of human events. Reader focuses on sixteenth-century South America, where the indigenous potato enabled Spanish conquerors to feed thousands of conscripted native people; eighteenth-century Europe, where the nutrition-packed potato brought about a population explosion; and today’s global world, where the potato is an essential food source but also the world’s most chemically-dependent crop. Where potatoes have been adopted as a staple food, social change has always followed. It may be “just” a humble vegetable, John Reader shows, yet the history of the potato has been anything but dull.

    But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr's students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments. As a result, questioning the status quo long meant professional ruin. And yet, from the 1920s to today, physicists like John Bell, David Bohm, and Hugh Everett persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and of the courageous scientists who dared to stand up for truth.

    One of the most coveted tools in a spy's arsenal, a zero day has the power to silently spy on your iPhone, dismantle the safety controls at a chemical plant, alter an election, and shut down the electric grid (just ask Ukraine).For decades, under cover of classification levels and non-disclosure agreements, the United States government became the world's dominant hoarder of zero days. U.S. government agents paid top dollar-first thousands, and later millions of dollars- to hackers willing to sell their lock-picking code and their silence. Then the United States lost control of its hoard and the market. Now those zero days are in the hands of hostile nations and mercenaries who do not care if your vote goes missing, your clean water is contaminated, or our nuclear plants melt down.Filled with spies, hackers, arms dealers, and a few unsung heroes, written like a thriller and a reference, This Is How They Tell Me the World Ends is an astonishing feat of journalism. Based on years of reporting and hundreds of interviews, The New York Times reporter Nicole Perlroth lifts the curtain on a market in shadow, revealing the urgent threat faced by us all if we cannot bring the global cyber arms race to heel.
