It now has 600,000 to a million page hits daily. Every now and then, Munroe would get emails asking him to arbitrate a science debate. 'My friend and I were arguing about what would happen if a bullet got struck by lightning, and we agreed that you should resolve it . . . ' He liked these questions so much that he started up What If. If your cells suddenly lost the power to divide, how long would you survive? How dangerous is it, really, to be in a swimming pool in a thunderstorm? If we hooked turbines to people exercising in gyms, how much power could we produce? What if everyone only had one soulmate?When (if ever) did the sun go down on the British empire? How fast can you hit a speed bump while driving and live?What would happen if the moon went away?In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators. His responses are masterpieces of clarity and hilarity, studded with memorable cartoons and infographics. They often predict the complete annihilation of humankind, or at least a really big explosion. Far more than a book for geeks, WHAT IF: Serious Scientific Answers to Absurd Hypothetical Questions explains the laws of science in operation in a way that every intelligent reader will enjoy and feel much the smarter for having read.

    Now the greatest event of the twentieth century

    He is known for both his breakthroughs in theoretical physics as well as his ability to make complex concepts accessible for all, and was beloved for his mischievous sense of humor. At the time of his death, Hawking was working on a final project: a book compiling his answers to the "big" questions that he was so often posed--questions that ranged beyond his academic field. Within these pages, he provides his personal views on our biggest challenges as a human race, and where we, as a planet, are heading next. Each section will be introduced by a leading thinker offering his or her own insight into Professor Hawking's contribution to our understanding.

    Why is glass see-through? What makes elastic stretchy? Why does a paper clip bend? Why does any material look and behave the way it does? These are the sorts of questions that Mark Miodownik a globally-renowned materials scientist has spent his life exploring In this book he examines the materials he encounters in a typical morning, from the steel in his razor and the graphite in his pencil to the foam in his sneakers and the concrete in a nearby skyscraper.

    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.

    Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    "A stunning memoir from the astronaut who spent a record-breaking year aboard the International Space Station – a candid account of his remarkable voyage, the journeys that preceded it, and his colorful formative years." Inside book cover comments.

    A riveting account of three heroic astronauts who took one of the most dangerous space flights ever, from the New York Times bestselling author of Shadow Divers. In early 1968, the Apollo program was on shaky footing. President Kennedy's end-of-decade deadline to put a man on the Moon was in jeopardy, and the Soviets were threatening to pull ahead in the space race. By August 1968, with its back against the wall, NASA decided to scrap its usual methodical approach and shoot for the heavens. With just four months to prepare--a fraction of the normal time--the agency would send the first men in history to the Moon. In a year of historic violence and discord--the Tet offensive, the assassinations of MLK and RFK, the Chicago DNC riots--the Apollo 8 mission was the boldest test of what America could do. With a focus on astronauts Frank Borman, Jim Lovell, and Bill Anders, and their wives and children, this is a vivid, gripping, you-are-there narrative that shows anew the epic danger involved, and the singular bravery it took, for man to leave Earth for the first time--and to arrive at a new world.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    As a flight director in NASA’s Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race. He helped to launch Alan Shepard and John Glenn, then assumed the flight director’s role in the Gemini program, which he guided to fruition. With his teammates, he accepted the challenge to carry out President John F. Kennedy’s commitment to land a man on the Moon before the end of the 1960s. Kranz recounts these thrilling historic events and offers new information about the famous flights. What appeared as nearly flawless missions to the Moon were, in fact, a series of hair-raising near misses. When the space technology failed, as it sometimes did, the controllers’ only recourse was to rely on their skills and those of their teammates. He reveals behind-the-scenes details to demonstrate the leadership, discipline, trust, and teamwork that made the space program a success. A fascinating firsthand account by a veteran mission controller of one of America’s greatest achievements, Failure is Not an Option reflects on what has happened to the space program and offers his own bold suggestions about what we ought to be doing in space now.

    Gleick's story begins at the turn of the twentieth century with the young H. G. Wells writing and rewriting the fantastic tale that became his first book, an international sensation, The Time Machine. A host of forces were converging to transmute the human understanding of time, some philosophical and some technological the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks. Gleick tracks the evolution of time travel as an idea in the culture from Marcel Proust to Doctor Who, from Woody Allen to Jorge Luis Borges. He explores the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that is unsettling our own moment: the instantaneous wired world, with its all-consuming present and vanishing future.

    A playful, entertaining, and mind-bending introduction to modern physics, it's already a major bestseller in Italy and the United Kingdom. Carlo Rovelli offers surprising—and surprisingly easy to grasp—explanations of general relativity, quantum mechanics, elementary particles, gravity, black holes, the complex architecture of the universe, and the role humans play in this weird and wonderful world. He takes us to the frontiers of our knowledge: to the most minute reaches of the fabric of space, back to the origins of the cosmos, and into the workings of our minds. “Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and the beauty of the world,” Rovelli writes. “And it’s breathtaking.”

    Armstrong become the first person to step on the surface of another heavenly body. Perhaps no words in human history became better known than those few he uttered at that historic moment. In a penetrating exploration of American hero worship, Hansen addresses the complex legacy of the First Man, as an astronaut and an individual.

    It is a book for those who were part of Apollo and want to recapture the experience and for those of a new generation who want to know how it was done. It is an opinion shared by many Apollo veterans. Republished in 2004 with a new Foreword by the authors.

    Nixon had left the White House in disgrace, the nation was reeling from the catastrophe of Vietnam, and in 1979--the year the book appeared--Americans were being held hostage by Iranian militants. Yet it was exactly the anachronistic courage of his subjects that captivated Wolfe. In his foreword, he notes that as late as 1970, almost one in four career Navy pilots died in accidents. "The Right Stuff," he explains, "became a story of why men were willing--willing?--delighted!--to take on such odds in this, an era literary people had long since characterized as the age of the anti-hero." Wolfe's roots in New Journalism were intertwined with the nonfiction novel that Truman Capote had pioneered with In Cold Blood. As Capote did, Wolfe tells his story from a limited omniscient perspective, dropping into the lives of his "characters" as each in turn becomes a major player in the space program. After an opening chapter on the terror of being a test pilot's wife, the story cuts back to the late 1940s, when Americans were first attempting to break the sound barrier. Test pilots, we discover, are people who live fast lives with dangerous machines, not all of them airborne. Chuck Yeager was certainly among the fastest, and his determination to push through Mach 1--a feat that some had predicted would cause the destruction of any aircraft--makes him the book's guiding spirit. Yet soon the focus shifts to the seven initial astronauts. Wolfe traces Alan Shepard's suborbital flight and Gus Grissom's embarrassing panic on the high seas (making the controversial claim that Grissom flooded his Liberty capsule by blowing the escape hatch too soon). The author also produces an admiring portrait of John Glenn's apple-pie heroism and selfless dedication. By the time Wolfe concludes with a return to Yeager and his late-career exploits, the narrative's epic proportions and literary merits are secure. Certainly The Right Stuff is the best, the funniest, and the most vivid book ever written about America's manned space program. --Patrick O'Kelley
