The ability to duplicate that process in a lab, once thought impossible, may now be closer than we think. Today, teams of scientists around the world are being assembled by the boldest entrepreneurs, big business, and governments to solve what is the most difficult technological challenge humanity has ever faced: building the equivalent of a star on earth. If their plans to capture star power are successful, they will unlock thousands, potentially millions, of years of clean, carbon-free energy. Not only would controlled nuclear fusion help solve the climate crisis, it could also make other highly desired technological ambitions possible—like journeying to the stars. Given the rising alarm over deterioration of the environment, and the strides being made in laser and magnetic field technology, powerful momentum is gathering behind fusion and the possibilities it offers. In The Star Builders, award-winning young plasma physicist Arthur Turrell “offers an optimistic outlook for the future of fusion power and is adamant about the need to invest in it” (The New York Times). Turrell describes fascinating star machines with ten times as many parts as the NASA Space Shuttle, and structures that extend over 400 acres in an accessible and entertaining account, spotlighting the individuals, firms, and institutions racing for the finish line: science-minded entrepreneurs like Jeff Bezos and Peter Thiel, companies like Goldman Sachs and Google, universities like Oxford and MIT, and virtually every rich nation. It’s an exciting and game-changing international quest that will make all of us winners.

    Whether they've arrived via rocket, flying saucer, or plain old teleportation, they've been invading, infiltrating, or inspiring us for decades, and they've fascinated moviegoers and television watchers for more than fifty years. About half of us believe that aliens really exist, and millions are convinced they've visited Earth. For twenty-five years, SETI has been looking for the proof, and as the program's senior astronomer, Seth Shostak explains in this engrossing book, it's entirely possible that before long conclusive evidence will be found. His informative, entertaining report offers an insider's view of what we might realistically expect to discover light-years away among the stars. Neither humanoids nor monsters, says Shostak; in fact, biological intelligence is probably just a precursor to machine beings, enormously advanced artificial sentients whose capabilities and accomplishments may have developed over billions of years and far exceed our own. As he explores what, if anything, they would tell us and what their existence would portend for humankind and the cosmos, he introduces a colorful cast of characters and provides a vivid, state-of-the-art account of the past, present, and future of our search for extraterrestrial intelligence.

    Right?! Machine Learning is a branch of computer science that wants to stop programming computers using a detailed list of commands to follow blindly. Instead, their aim is to implement high-level routines that teach computers how to approach new and unknown problems – these are called algorithms. In practice, they want to give computers the ability to Learn and to Adapt. We can use these algorithms to obtain insights, recognize patterns and make predictions from data, images, sounds or videos we have never seen before – or even knew existed. Unfortunately, the true power and applications of today’s Machine Learning Algorithms remain deeply misunderstood by most people. Through this book I want fix this confusion, I want to shed light on the most relevant Machine Learning Algorithms used in the industry. I will show you exactly how each algorithm works, why it works and when you should use it.

    His grand meteorological project had failed. Yet only a decade later, FitzRoy's storm warning system and "forecasts" would return, the model for what we use today.In an age when a storm at sea was evidence of God's wrath, nineteenth-century meteorologists had to fight against convention and religious dogma. Buoyed by the achievements of the Enlightenment, a generation of mavericks set out to decipher the secrets of the atmosphere and predict the future. Among them were Luke Howard, the first to classify clouds; Francis Beaufort, who quantified the winds; James Glaisher, who explored the upper atmosphere in a hot-air balloon; Samuel Morse, whose electric telegraph gave scientists the means by which to transmit weather warnings; and FitzRoy himself, master sailor, scientific pioneer, and founder of the U.K.'s national weather service.Reputations were built and shattered. Fractious debates raged over decades between scientists from London and Galway, Paris and New York. Explaining the atmosphere was one thing, but predicting what it was going to do seemed a step too far. In 1854, when a politician suggested to the Commons that Londoners might soon know the weather twenty-four hours in advance, the House roared with laughter.Peter Moore's The Weather Experiment navigates treacherous seas and rough winds to uncover the obsession that drove these men to great invention and greater understanding.

    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.

    Among them would be history makers, including the first American woman and the first African American in space. This assembly of astronauts would carry NASA through the most tumultuous years of the space shuttle program. Four would die on Challenger. USAF Colonel Mike Mullane was a member of this astronaut class, and Riding Rockets is his story -- told with a candor never before seen in an astronaut's memoir. Mullane strips the heroic veneer from the astronaut corps and paints them as they are -- human. His tales of arrested development among military flyboys working with feminist pioneers and post-doc scientists are sometimes bawdy, often hilarious, and always entertaining. Mullane vividly portrays every aspect of the astronaut experience -- from telling a female technician which urine-collection condom size is a fit; to walking along a Florida beach in a last, tearful goodbye with a spouse; to a wild, intoxicating, terrifying ride into space; to hearing "Taps" played over a friend's grave. Mullane is brutally honest in his criticism of a NASA leadership whose bungling would precipitate the Challenger disaster. Riding Rockets is a story of life in all its fateful uncertainty, of the impact of a family tragedy on a nine-year-old boy, of the revelatory effect of a machine called Sputnik, and of the life-steering powers of lust, love, and marriage. It is a story of the human experience that will resonate long after the call of "Wheel stop."

    The PCs, the i- phones, the i-pods, the tablet PCs all will be a constant reminder of the genuine and witty ways that Steve handled and fondled. He was always lost in a world of his own. He hugged the glory and the downfalls with equal aloofness. Not once were his beliefs shattered. Throughout his life, he struggled and dared to bring his dreams come true. His dreams had a silvery lining of consistency, persuasion and intention. He was unique in every way. The life threatening disease of cancer could not prevent him from working till his last breath, literally. Though stubborn and dominant by nature he stood as a magician in the field of technology. Here is a simple gesture to pay him respect and honour. A magnificent journey presented authentically.

    This book, which greatly expands the companion PBS series, tell the stories of the visionaries--based on eyewitness accounts and newly discovered archival material--who helped America win the space race with the first lunar landing fifty years ago. In 1961, President John F. Kennedy proposed the nation spend twenty billion dollars to land a man on the Moon before the end of the decade. For the first time, Chasing the Moon reveals the unknown stories of the fascinating individuals whose imaginative work across several decades culminated in America's momentous achievement. More than a story of engineers and astronauts, the Moon landing--now celebrating its 50th anniversary--grew out of the dreams of science fiction writers, filmmakers, military geniuses and rule-breaking scientists. Going in depth to explore their stories beyond the PBS series, writer/producer Robert Stone--called "one of our most important documentary film makers" by Entertainment Weekly--brings these important figures to brilliant life. They include: * Science fiction author Arthur C. Clarke, whose writing inspired some of the key players in the Moon race. A scientific paper he wrote in his twenties led to the U.S. beating Russia in one area of space: communications satellites.* Wernher von Braun, the Nazi military genius who oversaw Hitler's rocket weapons program. After working on ballistic missiles for the U.S. Army, he was recruited by NASA to manage the creation of the Saturn V Moon rocket. * Astronaut Frank Borman, commander of the first mission to circumnavigate the Moon, whose powerful testimony before Congress in 1967 decisively saved the U.S. lunar program from being cancelled. * Poppy Northcutt, a young mathematician who was the first woman to work in Mission Control. Her media exposure as a unique presence in this all-male world allowed her to stand up for equal rights for women and minorities.* Ed Dwight, an African-American astronaut candidate, recruited at the urging of the Kennedy White House to further the administration's civil rights agenda. But not everyone welcomed his inclusion.Setting these key players in the political, social, and cultural climate of the time, and including captivating photos throughout, Chasing the Moon focuses on the science and the history, but most importantly, the extraordinary individuals behind what was undoubtedly the greatest human achievement of the twentieth century.

    They passed the same battery of tests at the legendary Lovelace Foundation as did the Mercury 7 astronauts, but they were summarily dismissed by the boys’ club at NASA and on Capitol Hill. The USSR sent its first woman into space in 1963; the United States did not follow suit for another twenty years. For the first time, Martha Ackmann tells the story of the dramatic events surrounding these thirteen remarkable women, all crackerjack pilots and patriots who sometimes sacrificed jobs and marriages for a chance to participate in America’s space race against the Soviet Union. In addition to talking extensively to these women, Ackmann interviewed Chuck Yeager, John Glenn, Scott Carpenter, and others at NASA and in the White House with firsthand knowledge of the program, and includes here never-before-seen photographs of the Mercury 13 passing their Lovelace tests. Despite the crushing disappointment of watching their dreams being derailed, the Mercury 13 went on to extraordinary achievement in their lives: Jerrie Cobb, who began flying when she was so small she had to sit on pillows to see out of the cockpit, dedicated her life to flying solo missions to the Amazon rain forest; Wally Funk, who talked her way into the Lovelace trials, went on to become one of the first female FAA investigators; Janey Hart, mother of eight and, at age forty, the oldest astronaut candidate, had the political savvy to steer the women through congressional hearings and later helped found the National Organization for Women. A provocative tribute to these extraordinary women, The Mercury 13 is an unforgettable story of determination, resilience, and inextinguishable hope.From the Hardcover edition.

    It is an extraordinary account of courage and fortitude. ‘We were doing about 620 miles-per-hour, 200 feet above the desert, in total darkness. Everything was running on rails as we approached the target. Then all hell broke loose.  I remember the missile being fired at us; I broke left and shouted, “Chaff!”   ‘ All I could see was a flame, like a very large firework, coming towards me. Then there was a huge white flash. I remember an enormous wind and then I was knocked unconscious.  My last thoughts were that I was going to die. ’ In 1990, Iraqi dictator Saddam Hussein ordered the invasion and occupation of neighbouring Kuwait, setting in motion a chain of events that had unimaginable political, military and personal repercussions, which still reverberate around the globe today.This is the story of the aircrew at the heart of Operation Desert Storm, almost none of whom had any prior experience of armed combat. It is the story of the Tornado’s missions, of those who did not return - and of the families who watched and waited as one of the most complex conflicts in recent history unfolded live on television. It is a story of untold fear and suffering, and astounding courage in the face of hitherto unimaginable adversity.

    The effects of homeopathy don’t go away under rigorous scientific conditions. The laws of nature aren’t what they used to be. Thirty years on, no one has an explanation for a seemingly intelligent signal received from outer space. The US Department of Energy is re-examining cold fusion because the experimental evidence seems too solid to ignore. The placebo effect is put to work in medicine while doctors can’t agree whether it even exists.In an age when science is supposed to be king, scientists are beset by experimental results they simply can’t explain. But, if the past is anything to go by, these anomalies contain the seeds of future revolutions. While taking readers on an entertaining tour d’horizon of the strangest of scientific findings – involving everything from our lack of free will to Martian methane that offers new evidence of life on the planet – Michael Brooks argues that the things we don’t understand are the key to what we are about to discover.This mind-boggling but entirely accessible survey of the outer limits of human knowledge is based on a short article by Michael Brooks for New Scientist magazine. It became the sixth most circulated story on the internet in 2005, and provoked widespread comment and compliments (Google “13 things that do not make sense” to see).Michael Brooks has now dug deeply into those mysteries, with extraordinary results.

    "It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating—the best known of these methods—and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves—James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson—Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.
