Pegasus Bridge was the first engagement of D-Day, the turning point of World War II.This gripping account of it by acclaimed author Stephen Ambrose brings to life a daring mission so crucial that, had it been unsuccessful, the entire Normandy invasion might have failed. Ambrose traces each step of the preparations over many months to the minute-by-minute excitement of the hand-to-hand confrontations on the bridge. This is a story of heroism and cowardice, kindness and brutality—the stuff of all great adventures.

    "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.

    In this masterly synthesis, Arthur Koestler cuts through the sterile distinction between 'sciences' and 'humanities' to bring to life the whole history of cosmology from the Babylonians to Newton. He shows how the tragic split between science and religion arose and how, in particular, the modern world-view replaced the medieval world-view in the scientific revolution of the seventeenth century. He also provides vivid and judicious pen-portraits of a string of great scientists and makes clear the role that political bias and unconscious prejudice played in their creativity.

    All that mattered to Neil as he searched for a safe spot to land was that boulders littered the surface below. "Thirty seconds," called mission control. In truth, the flight controllers were now no more than spectators, just like everybody else. No more needed to be said.It was down to Armstrong.'Simultaneously connected and separated by television, millions of people around the world held their breath as a human being looked back at them from the surface of the Moon. Yet who were these men capable of such an achievement? How did the passionate Buzz Aldrin, inscrutable Michael Collins and enigmatic Neil Armstrong learn to depend on one another as they endured the most intense period of their lives?From the personal tragedies and triumphs they encountered along the way to the terrifying climax of a mission that redefined humanity, Moonshot - now also a major TV factual-drama - draws on interviews with many of the leading participants and hundreds of hours of archive material to tell the compelling true story of an event that captured the imagination of generations, then and now.

    In the 1960s most computers filled an entire room, but the spacecraft's computer was required to be compact and low power. Although people today find it difficult to accept that it was possible to control a spacecraft using such a 'primitive' computer, it nevertheless had capabilities that are advanced even by today's standards.This is the first book to fully describe the Apollo guidance computer's architecture, instruction format and programs used by the astronauts. As a comprehensive account, it will span the disciplines of computer science, electrical and aerospace engineering. However, it will also be accessible to the 'space enthusiast'. In short, the intention is for this to be the definitive account of the Apollo guidance computer.Frank O'Brien's interest in the Apollo program began as a serious amateur historian. About 12 years ago, he began performing research and writing essays for the Apollo Lunar Surface Journal, and the Apollo Flight Journal. Much of this work centered on his primary interests, the Apollo Guidance Computer (AGC) and the Lunar Module. These Journals are generally considered the canonical online reference on the flights to the Moon. He was then asked to assist the curatorial staff in the creation of the Cradle of Aviation Museum, on Long Island, New York, where he helped prepare the Lunar Module simulator, a LM procedure trainer and an Apollo space suit for display. He regularly lectures on the Apollo computer and related topics to diverse groups, from NASA's computer engineering conferences, the IEEE/ACM, computer festivals and university student groups.

    Whether exploring electromagnetic fields, the origin of hot chocolate, or DNA fingerprinting, these essays all illustrate the surprisingly circular nature of change. In "Room with (Half) a View," for instance, Burke muses about the partly obscured railway bridge outside his home on the Thames, a musing which sets off a chain of thought that leads from the bridge's engineer to Samuel Morse, to firearms inventor Sam Colt, and finally to a trombonist named Gustav Holst, who once lived in the very house that blocks Burke's view. So it goes with Burke's entertaining and informative essays as each one highlights the interconnectedness of seemingly unrelated events and innovations. Romantic poetry leads to brandy distillation; tonic water connects through Leibniz to the first explorers to reach the North Pole. This unique collection is sure to stimulate and delight history buffs, technophiles, and anyone else with a healthy intellectual curiosity.

    Based on original material and previously unavailable documents, this acclaimed book is the definitive biography of the man considered by many to be the founding father of modern electrical technology. Among Tesla's creations were the channeling of alternating current, fluorescent and neon lighting, wireless telegraphy, and the giant turbines that harnessed the power of Niagara Falls.

    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.

    This well-written, technically accurate, and even exciting account captures the urgency of the race to win World War II, the people behind the magnetrons, screens and antennae, and the use of radar in the cold war.

    In the clearest possible prose it differentiates the firmly established from the speculative and examines the claims of various fields such as string theory to approach a unified theory of everything. In doing so it challenges the orthodox consensus in those branches of cosmology, biology, and neuroscience that have ossified into dogma.Its striking analysis reveals underlying patterns of cooperation, complexification, and convergence that lead to the unique emergence in humans of a self-reflective consciousness that enables us to determine our future evolution.This groundbreaking book is destined to become a classic of scientific thinking.(67 black and white illustrations)

    Roosevelt’s death. Countdown 1945 tells the gripping true story of the turbulent days, weeks, and months to follow, leading up to August 6, 1945, when new President Harry Truman gives the order to unleash the world’s first atomic bomb. Featuring some of history’s most remarkable leaders, page-turning action, and vivid details, Countdown 1945 is a thrilling narrative of the covert meetings and pivotal developments that took place in the United States and around the world during the volatile spring and summer of 1945.Countdown 1945 takes readers inside the minds of the iconic and elusive figures who join the quest for the bomb, each for different reasons: the legendary Albert Einstein, who eventually calls his vocal support for the atomic bomb “the one great mistake in my life”; lead researcher Robert “Oppie” Oppenheimer and the Soviet spies who secretly infiltrate his team; the fiercely competitive pilots of the plane selected to drop the bomb; and many more. Perhaps most of all, Countdown 1945 is the story of an untested new president confronting a decision that he knows will change the world forever. Truman’s journey during these 116 days is a story of high drama: from the shock of learning of the bomb’s existence, to the conflicting advice he receives from generals like Eisenhower and George Marshall, to wrestling with the devastating carnage that will result if he gives the order to use America’s first weapon of mass destruction.But Countdown 1945 is more than a book about the atomic bomb. It’s also an unforgettable account of the lives of ordinary American and Japanese civilians in wartime—from “Calutron Girls” like Ruth Sisson in Oak Ridge, Tennessee, to ten-year-old Hiroshima resident Hideko Tamura, who survives the blast at ground zero but loses her mother, and later immigrates to the United States, where she lives to this day—as well as American soldiers fighting in the Pacific, waiting in fear for the order to launch a possible invasion of Japan. Told with vigor, intelligence, and humanity, Countdown 1945 is the definitive account of one of the most consequential moments in history.

    Explores the life and achievements of the rocketry pioneer who designed rockets for the Nazi war effort early in his career and later became a leading figure in the American space program.

    Beginning with the publication of Albert Einstein's theory of relativity, through the wild revolution of quantum mechanics, and up until the physics of the modern day (including the astonishing revelation, in 1998, that the Universe is not only expanding, but doing so at an ever-quickening pace), much of what physicists have seen in our Universe suggests that much of our Universe is unseen—that we live in a dark cosmos.Everyone knows that there are things no one can see—the air you're breathing, for example, or, to be more exotic, a black hole. But what everyone does not know is that what we can see—a book, a cat, or our planet—makes up only 5 percent of the Universe. The rest—fully 95 percent—is totally invisible to us; its presence discernible only by the weak effects it has on visible matter around it.This invisible stuff comes in two varieties—dark matter and dark energy. One holds the Universe together, while the other tears it apart. What these forces really are has been a mystery for as long as anyone has suspected they were there, but the latest discoveries of experimental physics have brought us closer to that knowledge. Particle physicist Dan Hooper takes his readers, with wit, grace, and a keen knack for explaining the toughest ideas science has to offer, on a quest few would have ever expected: to discover what makes up our dark cosmos.

    In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.   In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars—and to think critically about what’s out there, no matter how strange it seems.

    With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.
