Yuri Gagarin is one of the great heroes of the twentieth century, but the details of his life and the Russian space effort have been shrouded in secrecy: even the names of the engineers who worked with Gagarin were a mystery to the West for many years.Starman is the first book to tell the compelling story behind Gagarin's life and his audacious first flight into space aboard a converted nuclear weapon.He was once the most famous man in the world yet in his life, as in death, he was a man the world knew almost nothing about.

    A simple web search picks out a handful of relevant needles from the world's biggest haystack: the billions of pages on the World Wide Web. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers; and we use digital signatures to verify the identity of the websites we visit. How do our computers perform these tasks with such ease? This is the first book to answer that question in language anyone can understand, revealing the extraordinary ideas that power our PCs, laptops, and smartphones. Using vivid examples, John MacCormick explains the fundamental "tricks" behind nine types of computer algorithms, including artificial intelligence (where we learn about the "nearest neighbor trick" and "twenty questions trick"), Google's famous PageRank algorithm (which uses the "random surfer trick"), data compression, error correction, and much more. These revolutionary algorithms have changed our world: this book unlocks their secrets, and lays bare the incredible ideas that our computers use every day.

    Nearly a half-century after Neil Armstrong walked on the moon, these Space Barons-most notably Elon Musk and Jeff Bezos, along with Richard Branson and Paul Allen-are using Silicon Valley-style innovation to dramatically lower the cost of space travel, and send humans even further than NASA has gone. These entrepreneurs have founded some of the biggest brands in the world-Amazon, Microsoft, Virgin, Tesla, PayPal-and upended industry after industry. Now they are pursuing the biggest disruption of all: space. Based on years of reporting and exclusive interviews with all four billionaires, this authoritative account is a dramatic tale of risk and high adventure, the birth of a new Space Age, fueled by some of the world's richest men as they struggle to end governments' monopoly on the cosmos. The Space Barons is also a story of rivalry-hard-charging startups warring with established contractors, and the personal clashes of the leaders of this new space movement, particularly Musk and Bezos, as they aim for the moon and Mars and beyond.

    Many still vividly remember exactly where they were and what they were doing when they heard about the tragedy. In The Challenger Launch Decision, Diane Vaughan recreates the steps leading up to that fateful decision, contradicting conventional interpretations to prove that what occurred at NASA was not skulduggery or misconduct but a disastrous mistake.Journalists and investigators have historically cited production problems and managerial wrong-doing as the reasons behind the disaster. The Presidential Commission uncovered a flawed decision-making process at the space agency as well, citing a well-documented history of problems with the O-ring and a dramatic last-minute protest by engineers over the Solid Rocket Boosters as evidence of managerial neglect.Why did NASA managers, who not only had all the information prior to the launch but also were warned against it, decide to proceed? In retelling how the decision unfolded through the eyes of the managers and the engineers, Vaughan uncovers an incremental descent into poor judgment, supported by a culture of high-risk technology. She reveals how and why NASA insiders, when repeatedly faced with evidence that something was wrong, normalized the deviance so that it became acceptable to them.No safety rules were broken. No single individual was at fault. Instead, the cause of the disaster is a story not of evil but of the banality of organizational life. This powerful work explains why the Challenger tragedy must be reexamined and offers an unexpected warning about the hidden hazards of living in this technological age.

    From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy.Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world’s most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

    What they don't realize—and what Daniel Hillis's short book brilliantly demonstrates—is that computers' seemingly complex operations can be broken down into a few simple parts that perform the same simple procedures over and over again.Computer wizard Hillis offers an easy-to-follow explanation of how data is processed that makes the operations of a computer seem as straightforward as those of a bicycle. Avoiding technobabble or discussions of advanced hardware, the lucid explanations and colorful anecdotes in The Pattern on the Stone go straight to the heart of what computers really do.Hillis proceeds from an outline of basic logic to clear descriptions of programming languages, algorithms, and memory. He then takes readers in simple steps up to the most exciting developments in computing today—quantum computing, parallel computing, neural networks, and self-organizing systems.Written clearly and succinctly by one of the world's leading computer scientists, The Pattern on the Stone is an indispensable guide to understanding the workings of that most ubiquitous and important of machines: the computer.

    Nearly four decades later, as the world's oldest astronaut, his courage reveted a nation. But these two historical events only bracketed a life that covers the sweep of an extraordinary century.John Glenn's autobiography spans the seminal events of the twentieth century. It is a story that begins with his childhood in Ohio where he learned the importance of family, community, and patriotism. He took these values with him as a marine fighter pilot during World War II and into the skies over Korea, for which he would be decorated. Always a gifted flier, it was during the war that he contemplated the unlimited possibilities of aviation and its frontiers.We see the early days of NASA, where he first served as a backup pilot for astronauts Alan Shepard and Gus Grissom. In 1962 Glenn piloted the Mercury-Atlas 6 Friendship 7 spacecraft on the first manned orbital mission of the United States. Then came several years in international business, followed by a twenty-four year career as a U.S. Senator-and in 1998 a return to space for his remarkable Discover mission at the age of seventy-seven.

    The fantastic journey began in 1977, before the first episode of Cosmos aired. The mission was planned as a grand tour beyond the moon; beyond Mars, Jupiter, and Saturn; and maybe even into interstellar space. The fact that it actually happened makes this humanity's greatest space mission.In The Interstellar Age, award-winning planetary scientist Jim Bell reveals what drove and continues to drive the members of this extraordinary team, including Ed Stone, Voyager's chief scientist and the one-time head of NASA's Jet Propulsion Lab; Charley Kohlhase, an orbital dynamics engineer who helped to design many of the critical slingshot maneuvers around planets that enabled the Voyagers to travel so far; and the geologist whose Earth-bound experience would prove of little help in interpreting the strange new landscapes revealed in the Voyagers' astoundingly clear images of moons and planets.Speeding through space at a mind-bending eleven miles a second, Voyager 1 is now beyond our solar system's planets. It carries with it artifacts of human civilization. By the time Voyager passes its first star in about 40,000 years, the gold record on the spacecraft, containing various music and images including Chuck Berry's "Johnny B. Goode," will still be playable.

    All three astronauts were experienced pilots and had dreams of one day walking on the moon, but little did they know, nor did anyone else, that once they entered the spacecraft that cold winter day they would never leave it alive. The Apollo program would be perilously close to failure before it ever got off the ground. But rather than dooming the space program, this tragedy caused the spacecraft to be completely overhauled, creating a stellar flying machine to achieve the program’s primary goal: putting man on the moon. Apollo 1 is a candid portrayal of the astronauts, the disaster that killed them, and its aftermath. In it, readers will learn: How the Apollo 1 spacecraft was doomed from the start, with miles of uninsulated wiring and tons of flammable materials in a pure oxygen atmosphere, along with a hatch that wouldn’t open How, due to political pressure, the government contract to build the Apollo 1 craft went to a bidder with an inferior plan How public opinion polls were beginning to turn against the space control before the tragedy and got much worse after Apollo 1 is about America fulfilling its destiny of man setting foot on the moon. It’s also about the three American heroes who lost their lives in the tragedy, but whose lives were not lost in vain.

    But among the talented men (and later women) who worked in mission control, the room located on the third floor of Building 30—at what is now Johnson Space Center—would become known by many as “The Cathedral.” These members of the space program were the brightest of their generations, making split-second decisions that determined the success or failure of a mission. The flight controllers, each supported by a staff of specialists, were the most visible part of the operation, running the missions, talking to the heavens, troubleshooting issues on board, and, ultimately, attempting to bring everyone safely back home. None of NASA’s storied accomplishments would have been possible without these people. Interviews with dozens of individuals who worked in the historic third-floor mission control room bring the compelling stories to life. Go, Flight! is a real-world reminder of where we have been and where we could go again given the right political and social climate.

    US President Nixon called it the greatest week since creation. In the most authoritative book ever written about Apollo, David Whitehouse reveals the true drama behind the mission, telling the story in the words of those who took part – based around exclusive interviews with the key players. This enthralling book takes us from the early rocket pioneers to the shock America received from the Soviets’ launch of the first satellite, Sputnik; from the race to put the first person into space, through President Kennedy’s enthusiasm and later doubts, to the astronauts’ intense competition to leave the first footprint.In celebration of the 50th Anniversary of the moon landing, here is the story as told by the crew of Apollo 11 and the many other astronauts who paved the way or followed themselves after the first man to walk on the moon, Neil Armstrong, alongside Buzz Aldrin and Michael Collins. Astronauts, engineers, politicians, NASA officials, Soviet rivals – all tell their own story of a great moment of human achievement.

    In The Master Algorithm, Pedro Domingos lifts the veil to give us a peek inside the learning machines that power Google, Amazon, and your smartphone. He assembles a blueprint for the future universal learner--the Master Algorithm--and discusses what it will mean for business, science, and society. If data-ism is today's philosophy, this book is its bible.

    G. Lord was becoming a teenager in Southern California and her mother was dying of cancer, Lord's father-an archetypal, remote, rocket engineer- disappeared into his work at the Jet Propulsion Laboratory in Pasadena, building the space probes of the Mariner Mars 69 mission. Thirty years later, Lord found herself reporting on the JPL, triggering childhood memories and a desire to revisit her past as a way of understanding the ethos of rocket science. Astro Turf is the brilliant result of her journey of discovery.Remembering her pain at her father's absence, yet intrigued by what he did, Lord captures him on the page as she recalls her own youthful, eccentric fascination with science and space exploration. Into her family's saga she weaves the story of the legendary JPL- examining the complexities of its cultural history, from its start in 1936 to the triumphant Mars landings in 2004. She illuminates its founder, Frank Malina, whose brilliance in rocketry was shadowed by a flirtation with communism, driving him from the country even as we welcomed Wernher von Braun and his Nazi colleagues. Lord's own love of science fiction becomes a lens through which she views a profound cultural shift in the male-dominated world of space. And in pursuing the cause of her father's absence she stumbles on a hidden guilt, understanding "the anguish his proud silence caused both him and me, and how rooted that silence was in the culture of engineering."As in her acclaimed book Forever Barbie, which demystified an icon of feminine culture, Lord brings her penetrating insight to bear on a bastion of American masculinity, opening our eyes in unexpected and memorable ways.

    space program. In this meticulously researched and vividly written life, Michael J. Neufeld gives us a man of profound moral complexities, glorified as a visionary and vilified as a war criminal, a man whose brilliance and charisma were coupled with an enormous and, some would say, blinding ambition.As one of the leading developers of rocket technology for the German army, von Braun yielded to pressure to join the Nazi Party in 1937 and reluctantly became an SS officer in 1940. During the war, he supervised work on the V-2s, which were assembled by starving slave laborers in a secret underground plant and then fired against London and Antwerp. Thousands of prisoners died—a fact he well knew and kept silent about for as long as possible.When the Allies overran Germany, von Braun and his team surrendered to the Americans. The U.S. Army immediately recognized his skills and brought him and his colleagues to America to work on the development of guided missiles, in a covert operation that became known as Project Paperclip. He helped launch the first American satellite in 1958 and headed NASA’s launch-vehicle development for the Apollo Moon landing.Handsome and likable, von Braun dedicated himself to selling the American public on interplanetary travel and became a household name in the 1950s, appearing on Disney TV shows and writing for popular magazines. But he never fully escaped his past, and in later years he faced increasing questions as his wartime actions slowly came to light.Based on new sources, Von Braun is a brilliantly nuanced portrait of a man caught between morality and progress, between his dreams of the heavens and the earthbound realities of his life.
