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.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    Sutter emphasizes how amazing it is that we are part of such a huge, complex, and mysterious place. Through metaphors and uncomplicated language, Sutter breathes life into the science of astrophysics, unveiling how particles, forces, and fields interplay to create the greatest of cosmic dramas. Touched with the author's characteristic breezy, conversational style--which has made him a breakout hit on venues such as The Weather Channel, the Science Channel, and his own popular Ask a Spaceman! podcast--he conveys the fun and wonder of delving deeply into the physical processes of the natural universe. He weaves together the past and future histories of our universe with grounded descriptions of essential modern-day physics as well as speculations based on the latest research in cosmology. Topics include our place in the Milky Way galaxy; the cosmic web--a vast web-like pattern in which galaxies are arranged; the origins of our universe in the big bang; the mysteries of dark matter and dark energy; how science has dramatically changed our relationship to the cosmos; conjectures about the future of reality as we know it; and more.For anyone who has ever stared at the starry night sky and wondered how we humans on Earth fit into the big picture, this book is an essential roadmap.

    From dramatic, high-risk spacewalks to author Scott Parazynski’s death-defying quest to summit Mount Everest—his body ravaged by a career in space—readers will experience the life of an elite athlete, physician, and explorer.This intimate, compelling account offers a rare portrait of space exploration from the inside. A global nomad raised in the shadow of NASA’s Apollo missions, Parazynski never lost sight of his childhood dream to one day don a spacesuit and float outside the airlock. With deep passion, unbridled creativity, resilience, humility, and self-deprecation, Parazynski chases his dream of the ultimate adventure experience, again and again and again. In an era that transitioned from moon shots to the Space Shuttle, space station, and Mars research, Parazynski flies with John Glenn, tests jet packs, trains in Russia to become a cosmonaut, and flies five missions to outer space (including seven spacewalks) in his seventeen-year NASA career.An unparalleled, visceral opportunity to understand what it’s like to train for—and deploy to—a home in zero gravity, The Sky Below also portrays an astronaut’s engagement with the challenges of his life on Earth, including raising a beautiful autistic daughter and finding true love.

    The only question is when. In the meantime, we need to get much better at finding objects hurtling our way, and if they’re large enough to penetrate the atmosphere without burning up, figure out what to do about them. We owe many of science’s most important discoveries to the famed Meteor Crater, a mile-wide dimple on the Colorado Plateau created by an asteroid hit 50,000 years ago. In his masterfully researched Fire in the Sky, Dillow unpacks what the Crater has to tell us. Prior to the early 1900s, the world believed that all craters—on the Earth and Moon—were formed by volcanic activity. Not so. The revelation that Meteor Crater and others like it were formed by impacts with space objects has led to a now accepted theory about what killed off the dinosaurs, and it has opened up a new field of asteroid observation, which has recently brimmed with urgency. Dillow looks at great asteroid hits of the past and spends time with modern-day asteroid hunters and defense planning experts, including America’s first Planetary Defense Officer. Satellite sensors confirm that a Hiroshima-scale blast occurs in the atmosphere every year, and a smaller, one-kiloton blast every month. While Dillow makes clear that the objects above can be deadly, he consistently inspires awe with his descriptions of their size, makeup, and origins. At once a riveting work of popular science and a warning to not take for granted the space objects hurtling overhead, Fire in the Sky is, above all, a testament to our universe’s celestial wonders.

    Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out.Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds.Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

    Overnight, these women were transformed from military spouses into American royalty. They had tea with Jackie Kennedy, appeared on the cover of Life magazine, and quickly grew into fashion icons.Annie Glenn, with her picture-perfect marriage, was the envy of the other wives; JFK made it clear that platinum-blonde Rene Carpenter was his favorite; and licensed pilot Trudy Cooper arrived with a secret that needed to stay hidden from NASA. Together with the other wives they formed the Astronaut Wives Club, providing one another with support and friendship, coffee and cocktails.As their celebrity rose-and as divorce and tragedy began to touch their lives-the wives continued to rally together, forming bonds that would withstand the test of time, and they have stayed friends for over half a century. THE ASTRONAUT WIVES CLUB tells the story of the women who stood beside some of the biggest heroes in American history.

    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.

    In “Plays With Cars,” the former Porsche manager covers some of his most ridiculous decisions, like buying an old Land Rover sight unseen, taking a Mercedes AMG station wagon to a rural Georgia dragstrip, and roadtripping across the United States in a Lotus Elise without air conditioning. He’s also reviewed his former cars, which range from a Mercedes G-wagen to a Nissan Cube. Most importantly, he wrote this entire description himself in the third person.

    . . . Baker examines a wide range of the achievements that have made, and still make, America great again—and again.” —The Wall Street Journal All made in America: The skyscraper and subway car. The telephone and telegraph. The safety elevator and safety pin. Plus the microprocessor, amusement park, MRI, supermarket, Pennsylvania rifle, and Tennessee Valley Authority. Not to mention the city of Chicago or jazz or that magnificent Golden Gate Bridge.   What is it about America that makes it a nation of inventors, tinkerers, researchers, and adventurers—obsessive pursuers of the never-before-created? And, equally, what is it that makes America such a fertile place to explore, discover, and launch the next big thing?   In America the Ingenious, bestselling author Kevin Baker brings his gift of storytelling and eye for historical detail to the grand, and grandly entertaining, tale of American innovation. Here are the Edisons and Bells and Carnegies, and the stories of how they followed their passions and changed our world. And also the less celebrated, like Jacob Youphes and Loeb Strauss, two Jewish immigrants from Germany who transformed the way at least half the world now dresses (hint: Levi Strauss). And Leo Fender, who couldn’t play a note of music, midwifing rock ’n’ roll through his solid-body electric guitar and amplifier. And the many women who weren’t legally recognized as inventors, but who created things to make their lives easier that we use every day—like Josephine Cochran, inventor of the dishwasher, or Marion O’Brien Donovan, who invented a waterproof diaper cover. Or a guy with the improbable name of Philo Farnsworth, who, with his invention of television, upended communication as significantly as Gutenberg did.   At a time when America struggles with different visions of what it wants to be, America the Ingenious shows the extraordinary power of what works: how immigration leads to innovation, what a strong government and strong public education mean to a climate of positive practical change, and why taking the long view instead of looking for short-term gain pays off many times over, not only for investors and inventors, but for the rest of us whose lives are made better by the new.   America and its nation of immigrants have excelled at taking ideas from anywhere and transforming them into the startling, often unexpectedly beautiful creations that have shaped our world. This is that story.

      In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.   Richard Panek tells the dramatic story of how scientists reached this conclusion, and what they’re doing to find this "dark" matter and an even more bizarre substance called dark energy. Based on in-depth, on-site reporting and hundreds of interviews—with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin—the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.
