Now he brings his considerable talents to the history of one of math's most enduring puzzles: the seemingly paradoxical nature of infinity.Is infinity a valid mathematical property or a meaningless abstraction? The nineteenth-century mathematical genius Georg Cantor's answer to this question not only surprised him but also shook the very foundations upon which math had been built. Cantor's counterintuitive discovery of a progression of larger and larger infinities created controversy in his time and may have hastened his mental breakdown, but it also helped lead to the development of set theory, analytic philosophy, and even computer technology.Smart, challenging, and thoroughly rewarding, Wallace's tour de force brings immediate and high-profile recognition to the bizarre and fascinating world of higher mathematics.

    As was the case with Gore's first movie (An Inconvenient Truth), the movie is bursting with bad science, bad policy and some outright falsehoods. The storm events Gore addresses occur naturally, and there is little or no evidence they are being made worse from human activities: sea level is rising at the same rate it was before humans started burning fossil fuels; in Miami Beach the natural rise is magnified because buildings and streets were constructed on reclaimed swampland that has been sinking; the 9/11 memorial was not flooded by sea level rise from melting ice sheets, but a storm surge at high tide, which would have happened anyway and was not predicted by Gore in his first movie, as he claims; the Greenland ice sheet undergoes melt every summer, which was large in 2012 but then unusually weak in 2017; glaciers advance and retreat naturally, as evidenced by 1,000 to 2,000 year old tree stumps being uncovered in Alaska; rain gauge measurements reveal the conflict in Syria was not caused by reduced rainfall hurting farming there, and in fact the Middle East is greening from increasing CO2 in the atmosphere; agricultural yields in China have been rising, not falling as claimed by Gore. The renewable energy sources touted by Gore (wind and solar), while a laudable goal for our future, are currently very expensive: their federal subsidies per kilowatt-hour of energy produced are huge compared to coal, natural gas, and nuclear power. These costs are hidden from the public in increased federal and state tax rates. Gore is correct that "it is right to save humanity", but what we might need saving from the most are bad decisions that reduce prosperity and hurt the poor.

    Those that have liquid water. And maybe even life.She wonders how we might be able to take the our first ever high resolution picture of an exoplanet using the microchips found in mobile phones. And she meets world-leading astrophysicists to ask if within our lifetimes humans might step foot on an earth-like planet.An ITN production for Audible Originals.

    G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics.

     This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

     "Swimming Anatomy" includes 74 of the most effective swimming exercises, each with step-by-step descriptions and full-color anatomical illustrations highlighting the primary muscles in action. "Swimming Anatomy" goes beyond exercises by placing you on the starting block, in the water, and into the throes of competition. Illustrations of the active muscles for starts, turns, and the four competitive strokes (freestyle, breaststroke, butterfly, and backstroke) show you how each exercise is fundamentally linked to swimming performance. You'll also learn how exercises can be modified to target specific areas, improve your form in the water, and minimize common swimming injuries. Best of all, you'll learn how to put it all together to develop a training program based on your individual needs and goals. Whether you are training for a 50-meter freestyle race or the open-water stage of a triathlon, "Swimming Anatomy" will ensure you enter the water prepared to achieve every performance goal.

    For centuries, the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. Zero follows this number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe and its apotheosis as the mystery of the black hole. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for the theory of everything. Elegant, witty, and enlightening, Zero is a compelling look at the strangest number in the universe and one of the greatest paradoxes of human thought.

    For five years in his mid-twenties, he sailed on the BEAGLE around the world, exploring jungles, climbing mountains, trekking across deserts. With every new landfall, he had new adventures: he rode through bandit country, was thrown into jail by revolutionaries, took part in an armed raid with marines, survived two earthquakes, hunted and fished. He suffered the terrible cold and rain of Tierra del Fuego, the merciless heat of the Australian outback and the inner pangs of heartbreak. He also made the discoveries that finally led him to formulate his theory of Natural Selection as the driving force of evolution. The five-year voyage of the BEAGLE was the basis for all Darwin's later work; but it also turned him from a friendly idler into the greatest scientist of his century. Kevin Jackson is a writer, broadcaster and film-maker. His most recent book is Constellation of Genius: 1922 and All That Jazz (Farrar Strauss Giroux, 2013). He lives in Cambridge, England.

    But what should we change and how do we do it? Annabel Streets and Susan Saunders spent their 30s climbing the career ladder, having children and caring for elderly parents - all at the same time. By their 40s, they were exhausted, stressed, sleeping too little and rushing too much. They began to ask whether the prolonged ill health and dementia suffered by their parents was their inevitable future too - could they do anything to avoid requiring their own children to care for them in old age? Thus began THE AGE-WELL PROJECT. With incredible tenacity, Annabel and Susan read 50,000 scientific research papers on all aspects of ageing to find what advice cutting-edge research can offer us on how to ensure the longer lives we're living are healthy and happy. Putting their findings into practice, they found that the lifestyle changes they made were having incredible benefits on their health and wellbeing now - as well as for the future. Told with empathy and humour, in THE AGE-WELL PROJECT Annabel and Susan share the 50 key lessons they learned, the meals they cooked and the experts' tips they uncovered to make the second half of your life the best half of your life - happy, healthy and disease-free. Author BiographyAnnabel was a founder member of an award-winning marketing company, advising the chief executives of companies such as Sony, Reuters and the Financial Times. After four children, and at breaking point, she sold her company. Following a stint studying photography and producing a community cook book, she changed tack and wrote an award-winning novel The Joyce Girl which sold in 14 countries and was selected for the 2017 Berlin Film Festival.
