Here are up-close portraits of the maverick band of scientists & engineers who made the Skunk Works so renowned. Filled with telling personal anecdotes & high adventure, with narratives from the CIA & from Air Force pilots who flew the many classified, risky missions, this book is a portrait of the most spectacular aviation triumphs of the 20th century.

    Kai-Fu Lee—one of the world’s most respected experts on AI and China—reveals that China has suddenly caught up to the US at an astonishingly rapid and unexpected pace.In AI Superpowers, Kai-Fu Lee argues powerfully that because of these unprecedented developments in AI, dramatic changes will be happening much sooner than many of us expected. Indeed, as the US-Sino AI competition begins to heat up, Lee urges the US and China to both accept and to embrace the great responsibilities that come with significant technological power.Most experts already say that AI will have a devastating impact on blue-collar jobs. But Lee predicts that Chinese and American AI will have a strong impact on white-collar jobs as well. Is universal basic income the solution? In Lee’s opinion, probably not.  But he provides a clear description of which jobs will be affected and how soon, which jobs can be enhanced with AI, and most importantly, how we can provide solutions to some of the most profound changes in human history that are coming soon.

    He is also an obsessive gamer who has spent untold hours in front of his various video game consoles, playing titles such as Far Cry 2, Left 4 Dead, BioShock, and Oblivion for, literally, days. If you are reading this flap copy, the same thing can probably be said of you, or of someone you know. Until recently, Bissell was somewhat reluctant to admit to his passion for games. In this, he is not alone. Millions of adults spend hours every week playing video games, and the industry itself now reliably outearns Hollywood. But the wider culture seems to regard video games as, at best, well designed if mindless entertainment. Extra Lives is an impassioned defense of this assailed and misunderstood art form. Bissell argues that we are in a golden age of gaming—but he also believes games could be even better. He offers a fascinating and often hilarious critique of the ways video games dazzle and, just as often, frustrate. Along the way, we get firsthand portraits of some of the best minds (Jonathan Blow, Clint Hocking, Cliff Bleszinski, Peter Molyneux) at work in video game design today, as well as a shattering and deeply moving final chapter that describes, in searing detail, Bissell’s descent into the world of Grand Theft Auto IV, a game whose themes mirror his own increasingly self-destructive compulsions. Blending memoir, criticism, and first-rate reportage, Extra Lives is like no other book on the subject ever published. Whether you love video games, loathe video games, or are merely curious about why they are becoming the dominant popular art form of our time, Extra Lives is required reading.

    His quick mastery of quantum mechanics earned him a place at Los Alamos working on the Manhattan Project under J. Robert Oppenheimer, where the giddy young man held his own among the nation’s greatest minds. There, Feynman turned theory into practice, culminating in the Trinity test, on July 16, 1945, when the Atomic Age was born. He was only twenty-seven. And he was just getting started. In this sweeping biography, James Gleick captures the forceful personality of a great man, integrating Feynman’s work and life in a way that is accessible to laymen and fascinating for the scientists who follow in his footsteps.

    Who knew that he also was a pivotal figure in the development of the airplane, the hydrofoil, genetic engineering, and more? Charlotte Gray does, and she tells us how and why she brought to life the passionate mind and heart of the man behind so many amazing ideas and innovations. --Lauren Nemroff Some Questions for Charlotte Gray [image] 1. Most people picture Alexander Graham Bell as that grandfatherly looking man with a long white beard who invented the telephone. What's wrong with that image? The image of Alexander Graham Bell as a kindly Santa Claus figure is the one we all know: It is as familiar as the one of Einstein with his hair in a frizzy grey mass. But when Alexander Graham Bell was struggling to invent the telephone, he was a skinny, clean-shaven, neurotically intense young man and a hypochondriac, with obsessive work habits and a very volatile nature. Reading his letters and journals, I was shocked to discover how often he would ricochet between euphoria and depression. Invention was Alexander Graham Bell's passion, but I frequently wondered whether, if he had not had an early success and the right wife, his difficult personality would have prevented him achieving anything. I think it is important to revise the grandfatherly stereotype of Bell in order to show that invention is difficult, and inventors are not easy, placid people to live with. 2. In what way does Bell's genius different from other inventors of his age, such as Thomas Edison or the Wright brothers? The wonderful thing about the inventions of such nineteenth century giants as Bell, Edison and the Wright brothers is that, with a little bit of effort, even those of us who never did Grade 12 physics can actually understand how their inventions worked. One could never say that about today's microelectronic technology. Intuition and imagination were all crucial for the breakthroughs made by Edison, the Wright brothers and Bell. However, what sets Bell apart from Edison and the Wright brothers was that he didn't have an entrepreneurial bone in his body. He was more like a holdover from the eighteenth century Enlightenment, while the others were go-getting twentieth-century hustlers. Edison was always looking for financial backers; he announced his breakthroughs before he had even built working prototypes; he was one of the first inventors to put together a real R and D team at a purpose-built laboratory, at Menlo Park. He understood that invention is, in his own words, "One percent inspiration, ninety percent perspiration." Similarly the Wright Brothers were eager to make money out of their flying machines. They refused to share their technological breakthroughs, guarded their patents fiercely, and wouldn't give any demonstrations to the public of their biplanes. Bell was the opposite--totally absorbed in extending the frontiers of knowledge, and completely careless about commercial exploitation of his ideas. 3. Is it true that "necessity is the mother of invention" or is it something else? Invention has many mothers - the right materials, a widespread understanding that this will improve the world in some way, the right individual to pursue the elusive dream. In the case of the telephone, one can argue that there was no overwhelming necessity for a new form of communication: the telegraph had been working well for 30 years, and only a few people realized that a device that could carry the human voice, rather than the Morse code, would pull people together in a revolutionary way. As soon as telephones appeared in the market, their advantages were obvious. But there was still incredible resistance. In Britain, the upper classes were slow to acquire telephones because they posed a class issue: who should answer them? Everybody knew that, in a house with servants, the servant answered the door when the telegraph boy rang the bell. But should master or servant speak on the phone? The democratic nature of the telephone--anybody could use it, not just qualified operators--also shackled its spread. In Russia after the revolution, Stalin is said to have vetoed the idea of a modern telephone system. "It will unmake our work," the dictator decreed. "No greater instrument for counter-revolution and conspiracy can be imagined." So did necessity drive the invention of the telephone? No--when Bell first started speculating on its impact, people thought he was mad. But it quickly became a total necessity…imagine life without electronic communication today! 4. It was amazing to learn that Bell's mother and his wife were both deaf, and that from an early age he was immersed in research on the nature of sound and oral communication. How important were these personal relationships in shaping his outlook and inventions? One of my greatest surprises when I started research for Reluctant Genius was the discovery that Bell's first ambition was to be a teacher of the deaf, and that he remained committed to the cause of improved education for the hearing impaired throughout his life. I had no idea of this side of him, or of his long relationship with Helen Keller. The fact that the two most important women in his life, his mother and his wife, were deaf was of crucial importance both to his own work, and to his attitude to others. His respect for their intelligences and personalities meant that, unlike many of his contemporaries, he never assumed that deafness was linked to intellectual disability. Moreover, his scientific interest in their condition informed his telephone research. Because he knew why their ears didn't work, he understood how sound should reach the brain in a hearing person's ear, through the ear drum. None of his competitors made that intuitive leap. Their early attempts to build working telephones were foiled because they didn't include the diaphragm that mimicked the action of the ear drum, and which was the key feature of Bell's first phone. Lastly, Bell was also fascinated by the intergenerational transmission of deafness. This led to his research on genetics in general - and the program he initiated at his summer home, in Cape Breton, to breed a flock of "super sheep" that would always have twin births. 5. Bell's wife, Mabel Hubbard Bell, was a remarkable person in her own right. Why was it so important to tell her story? Too often, biographies of "Great Men" suggest they achieved everything by their own efforts. A few did, of course, but most depended on the support and encouragement of others--parents, partners, associates--to provide the right environment in which they could achieve their goals. Behind every great man….This was the case with Alexander Graham Bell. He would always have had his "Eureka Moment", in the summer of 1874, when he realized how a "talking telegraph" might work. But without Mabel, we probably would never have heard of him. He would not have patented the invention or found the business partners who helped him moved his invention from the laboratory to the market place. Mabel's father, Gardiner Hubbard, was his patent lawyer: Mabel herself ensured that he went to the Philadelphia Exposition, in 1876, to demonstrate his new apparatus. In later years, Mabel provided all kinds of other practical help, in ensuring that her exasperating husband could focus on his inventions. She handled the financial side of their marriage: she found qualified young men who could help him work on his flying machines: she was always cheering him up and stroking his ego when he got depressed. And she created, along with their two daughters, a warm family environment which gave balance to Bell's life - and which so many of his contemporaries, including Thomas Edison, never enjoyed. I was determined to give Mabel her due in the story of Bell. I found her such an attractive and intriguing figure. She was stone deaf, ten years younger than her husband, and their relationship began as a teacher-student one. It would be easy to assume that this brilliant, world famous man would be the dominant figure in the relationship. In fact, the reverse is true. 6. What do you think Bell would think of cell phones, the internet and other wireless means of communication? Bell himself anticipated "electric communication": he was very frustrated by how long it took for a letter from Nova Scotia to reach Europe. I'm sure he would be delighted by the internet. However, he would be appalled by the constant buzz of other technological advances, and the way we've allowed them to trump all other forms of human intercourse. This is a man who wouldn't have a telephone in his own study, because its ring would disturb his train of thought. He was a gracious, well-mannered man who would have been horrified by the way many of us let our cell phones to interrupt our face-to-face conversations. And if somebody pulled out a Blackberry and started punching into it while Bell was speaking of him--well, Alec would have muttered, "Shee-e-esh" (the nearest he ever got to swearing) and stomped out of the room. 7. What was the most exciting research discovery that you made? As a biographer, I have to say that my most exciting discovery was the wealth of material I had to work with. Because Alexander Graham Bell could never speak to his wife on the telephone, he and Mabel exchanged long, intimate, colourful letters whenever they were apart--and that was often. I was thrilled to discover, at the Alexander Graham Bell Historic Site in Baddeck, Nova Scotia, 180 three-ring binders of family correspondence (another set is housed at the Library of Congress, Washington.) These letters let me explore the inner-workings of the mind of a genius, and of a remarkable marriage, in a way that I had hardly dared hope for. I was also amazed at the range of Bell's activities. The telephone, the photophone (which sent sounds down beams of light), an early iron lung, a desalination process for salt water, flying machines, hydrofoils, genetic experiments…his scientific interests were enormously varied. And at the same time, he was doing so much else, for example with the Smithsonian Institute, and the National Geographic Society. And throughout his career, there was his long-running commitment to deaf education. It was hard not to be overwhelmed! 8. What are you working on right now? Yes, I'm already launched on my next biography. (In fact, I find it very hard not to start my next book before the previous one is even in the stores--I have a psychological need to live both my own life and someone else's!) My next project is a short biography of Nellie McClung, the Canadian author and political activist.

    Digital technologies—with hardware, software, and networks at their core—will in the near future diagnose diseases more accurately than doctors can, apply enormous data sets to transform retailing, and accomplish many tasks once considered uniquely human.In The Second Machine Age MIT’s Erik Brynjolfsson and Andrew McAfee—two thinkers at the forefront of their field—reveal the forces driving the reinvention of our lives and our economy. As the full impact of digital technologies is felt, we will realize immense bounty in the form of dazzling personal technology, advanced infrastructure, and near-boundless access to the cultural items that enrich our lives.Amid this bounty will also be wrenching change. Professions of all kinds—from lawyers to truck drivers—will be forever upended. Companies will be forced to transform or die. Recent economic indicators reflect this shift: fewer people are working, and wages are falling even as productivity and profits soar.Drawing on years of research and up-to-the-minute trends, Brynjolfsson and McAfee identify the best strategies for survival and offer a new path to prosperity. These include revamping education so that it prepares people for the next economy instead of the last one, designing new collaborations that pair brute processing power with human ingenuity, and embracing policies that make sense in a radically transformed landscape.A fundamentally optimistic book, The Second Machine Age alters how we think about issues of technological, societal, and economic progress.

    This behavior is very much different from what we humans are used to dealing with in our everyday lives, so naturally this subject is quite hard to comprehend for many. We believed that the best way to introduce the subject reliably is to start at the beginning, presenting the observations, thoughts and conclusions of each of the world’s greatest physicists through their eyes, one at a time. In this way we hope that the reader may take an enjoyable journey through the strange truths of quantum theory and understand why the conclusions of these great minds are what they are. This book starts with the most general view of the world and gradually leads readers to those new, unbelievable but real facts about the very nature of our universe.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.

    Tracy Kidder got a preview of this world in the late 1970s when he observed the engineers of Data General design and build a new 32-bit minicomputer in just one year. His thoughtful, prescient book, The Soul of a New Machine, tells stories of 35-year-old "veteran" engineers hiring recent college graduates and encouraging them to work harder and faster on complex and difficult projects, exploiting the youngsters' ignorance of normal scheduling processes while engendering a new kind of work ethic.These days, we are used to the "total commitment" philosophy of managing technical creation, but Kidder was surprised and even a little alarmed at the obsessions and compulsions he found. From in-house political struggles to workers being permitted to tease management to marathon 24-hour work sessions, The Soul of a New Machine explores concepts that already seem familiar, even old-hat, less than 20 years later. Kidder plainly admires his subjects; while he admits to hopeless confusion about their work, he finds their dedication heroic. The reader wonders, though, what will become of it all, now and in the future. —Rob Lightner

    How has Google done it? Veteran technology reporter Steven Levy was granted unprecedented access to the company, and in this revelatory book he takes readers inside Google headquarters—the Googleplex—to show how Google works.While they were still students at Stanford, Google cofounders Larry Page and Sergey Brin revolutionized Internet search. They followed this brilliant innovation with another, as two of Google’s earliest employees found a way to do what no one else had: make billions of dollars from Internet advertising. With this cash cow, Google was able to expand dramatically and take on other transformative projects: more efficient data centers, open-source cell phones, free Internet video (YouTube), cloud computing, digitizing books, and much more.The key to Google’s success in all these businesses, Levy reveals, is its engineering mind-set and adoption of such Internet values as speed, openness, experimentation, and risk taking. After its unapologetically elitist approach to hiring, Google pampers its engineers—free food and dry cleaning, on-site doctors and masseuses—and gives them all the resources they need to succeed. Even today, with a workforce of more than 23,000, Larry Page signs off on every hire.But has Google lost its innovative edge? With its newest initiative, social networking, Google is chasing a successful competitor for the first time. Some employees are leaving the company for smaller, nimbler start-ups. Can the company that famously decided not to be evil still compete?No other book has ever turned Google inside out as Levy does with In the Plex.

    The topics range from elementary to advanced - from algebra, trigonometry and calculus to vector analysis, Bessel functions, Legendre polynomials, and elliptic integrals.
