Having just completed his masterpiece, The General Theory of Relativity—which provided a brand-new theory of gravity and promised a new perspective on the cosmos as a whole—he set out at once to share his excitement with as wide a public as possible in this popular and accessible book.Here published for the first time as a Penguin Classic, this edition of Relativity features a new introduction by bestselling science author Nigel Calder.

    Now the greatest event of the twentieth century

    The glory days of the Apollo space program. NASA send Commander Jim Lovell and two other astronauts on America's fifth mission to the moon.Only fifty-five hours into the flight, disaster strikes. A mysterious explosion rocks the ship. Its oxygen and power begin draining away. Lovell and his crew watch as the cockpit grows darker, the air grows thinner, and the instruments wink out one by one.In this tale of astonishing courage, brilliant improvisation and thrilling adventure, the reader is transported right into the capsule during one of the worst disasters in the history of space exploration.

    From training to launch, from his historic spacewalk to re-entry, he reveals for readers of all ages the cutting-edge science behind his ground-breaking experiments, and the wonders of day-to-day life on board the International Space Station.The public were invited to submit questions using the hashtag #askanastronaut, and a selection are answered by Tim in the book, which will be accompanied with illustrations, diagrams and never-before-seen photos.Tim is pleased to announce that, as with his previous book, royalties received from the book will be donated to The Prince’s Trust.

    Richard Gott leads time travel out of the world of H. G. Wells and into the realm of scientific possibility. Building on theories posited by Einstein and advanced by scientists such as Stephen Hawking and Kip Thorne, Gott explains how time travel can actually occur. He describes, with boundless enthusiasm and humor, how travel to the future is not only possible but has already happened, and he contemplates whether travel to the past is also conceivable. Notable not only for its extraordinary subject matter and scientific brilliance, Time Travel in Einstein’s Universe is a delightful and captivating exploration of the surprising facts behind the science fiction of time travel.

    The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit.Now with the advent of a revolutionary new plan, all this has changed. leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with illustrations, photographs, and engaging anecdotes.The Case for Mars is not a vision for the far future or one that will cost us impossible billions. It explains step-by-step how we can use present-day technology to send humans to Mars within ten years; actually produce fuel and oxygen on the planet's surface with Martian natural resources; how we can build bases and settlements; and how we can one day "terraform" Mars--a process that can alter the atmosphere of planets and pave the way for sustainable life.

    Sixteen weeks later, Frank Borman, Jim Lovell, and Bill Anders were aboard the first manned spacecraft to depart Earth’s orbit, reach the moon, and return safely to Earth, delivering a tear-inducing Christmas Eve message along the way.

    Though his path to the heavens was riddled with setbacks and injury, Leland persevered to reach the stars.While training with NASA, Melvin suffered a severe injury that left him deaf. Leland was relegated to earthbound assignments, but chose to remain and support his astronaut family. His loyalty paid off. Recovering partial hearing, he earned his eligibility for space travel. He served as mission specialist for two flights aboard the shuttle Atlantis, working on the International Space Station.In this uplifting memoir, the former NASA astronaut and professional athlete offers an examination of the intersecting role of community, determination, and grace that align to shape our opportunities and outcomes. Chasing Space is not the story of one man, but the story of many men, women, scientists, and mentors who helped him defy the odds and live out an uncommon destiny.As a chemist, athlete, engineer and space traveler, Leland’s life story is a study in the science of achievement. His personal insights illuminate how grit and grace, are the keys to overcoming adversity and rising to success.

    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.

    Frizzle were a physics student of Stephen Hawking, she might have written THE UNIVERSE IN YOUR HAND, a wild tour through the reaches of time and space, from the interior of a proton to the Big Bang to the rough suburbs of a black hole. It's friendly, excitable, erudite, and cosmic."—Jordan Ellenberg, New York Times besteselling author of How Not To Be WrongQuantum physics, black holes, string theory, the Big Bang, dark matter, dark energy, parallel universes: even if we are interested in these fundamental concepts of our world, their language is the language of math. Which means that despite our best intentions of finally grasping, say, Einstein's Theory of General Relativity, most of us are quickly brought up short by a snarl of nasty equations or an incomprehensible graph.Christophe Galfard's mission in life is to spread modern scientific ideas to the general public in entertaining ways. Using his considerable skills as a brilliant theoretical physicist and successful young adult author, The Universe in Your Hand employs the immediacy of simple, direct language to show us, not explain to us, the theories that underpin everything we know about our universe. To understand what happens to a dying star, we are asked to picture ourselves floating in space in front of it. To get acquainted with the quantum world, we are shrunk to the size of an atom and then taken on a journey. Employing everyday similes and metaphors, addressing the reader directly, and writing stories rather than equations renders these astoundingly complex ideas in an immediate and visceral way.Utterly captivating and entirely unique, The Universe in Your Hand will find its place among other classics in the field.

    on July 16, 1969, the Apollo 11 rocket launched in the presence of more than a million spectators who had gathered to witness a truly historic event. It carried Neil Armstrong, Buzz Aldrin, and Mike Collins to the last frontier of human imagination: the moon. Rocket Men is the thrilling story of the moon mission, and it restores the mystery and majesty to an event that may have become too familiar for most people to realize what a stunning achievement it represented in planning, technology, and execution. Through interviews, twenty-three thousand pages of NASA oral histories, and declassified CIA documents on the space race, Craig Nelson re-creates a vivid and detailed account of the Apollo 11 mission. From the quotidian to the scientific to the magical, readers are taken right into the cockpit with Aldrin and Armstrong and behind the scenes at Mission Control. Rocket Men is the story of a twentieth-century pilgrimage; a voyage into the unknown motivated by politics, faith, science, and wonder that changed the course of history.

    This discovery dramatically reshaped how humans understood their place in the cosmos, and once and for all laid to rest the idea that the Milky Way galaxy was alone in the universe. Six years later, continuing research by Hubble and others forced Albert Einstein to renounce his own cosmic model and finally accept the astonishing fact that the universe was not immobile but instead expanding. The fascinating story of these interwoven discoveries includes battles of will, clever insights, and wrong turns made by the early investigators in this great twentieth-century pursuit. It is a story of science in the making that shows how these discoveries were not the work of a lone genius but the combined efforts of many talented scientists and researchers toiling away behind the scenes. The intriguing characters include Henrietta Leavitt, who discovered the means to measure the vast dimensions of the cosmos . . . Vesto Slipher, the first and unheralded discoverer of the universe’s expansion . . . Georges Lemaître, the Jesuit priest who correctly interpreted Einstein’s theories in relation to the universe . . . Milton Humason, who, with only an eighth-grade education, became a world-renowned expert on galaxy motions . . . and Harlow Shapley, Hubble’s nemesis, whose flawed vision of the universe delayed the discovery of its true nature and startling size for more than a decade.Here is a watershed moment in the history of astronomy, brought about by the exceptional combination of human curiosity, intelligence, and enterprise, and vividly told by acclaimed science writer Marcia Bartusiak.

    Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space: a multiverse in which you have an infinite number of doppelgängers, each reading this sentence in a distant universe; a multiverse comprising a vast ocean of bubble universes, of which ours is but one; a multiverse that endlessly cycles through time, or one that might be hovering millimeters away yet remains invisible; another in which every possibility allowed by quantum physics is brought to life. Or, perhaps strangest of all, a multiverse made purely of math.Greene, one of our foremost physicists and science writers, takes us on a captivating exploration of these parallel worlds and reveals how much of reality’s true nature may be deeply hidden within them. And, with his unrivaled ability to make the most challenging of material accessible and entertaining, Greene tackles the core question: How can fundamental science progress if great swaths of reality lie beyond our reach?Sparked by Greene’s trademark wit and precision, The Hidden Reality is at once a far-reaching survey of cutting-edge physics and a remarkable journey to the very edge of reality—a journey grounded firmly in science and limited only by our imagination.

    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

    During this time he has broken into a Space Station with a Swiss army knife, disposed of a live snake while piloting a plane, and been temporarily blinded while clinging to the exterior of an orbiting spacecraft. The secret to Col. Hadfield's success-and survival-is an unconventional philosophy he learned at NASA: prepare for the worst-and enjoy every moment of it. In An Astronaut's Guide to Life on Earth, Col. Hadfield takes readers deep into his years of training and space exploration to show how to make the impossible possible. Through eye-opening, entertaining stories filled with the adrenaline of launch, the mesmerizing wonder of spacewalks, and the measured, calm responses mandated by crises, he explains how conventional wisdom can get in the way of achievement-and happiness. His own extraordinary education in space has taught him some counterintuitive lessons: don't visualize success, do care what others think, and always sweat the small stuff. You might never be able to build a robot, pilot a spacecraft, make a music video or perform basic surgery in zero gravity like Col. Hadfield. But his vivid and refreshing insights will teach you how to think like an astronaut, and will change, completely, the way you view life on Earth-especially your own.
