    His inventions, patents, and theoretical work formed the basis of modern AC electricity, and contributed to the development of radio and television. Like his competitor Thomas Edison, Tesla was one of America's first celebrity scientists, enjoying the company of New York high society and dazzling the likes of Mark Twain with his electrical demonstrations. An astute self-promoter and gifted showman, he cultivated a public image of the eccentric genius. Even at the end of his life when he was living in poverty, Tesla still attracted reporters to his annual birthday interview, regaling them with claims that he had invented a particle-beam weapon capable of bringing down enemy aircraft.Plenty of biographies glamorize Tesla and his eccentricities, but until now none has carefully examined what, how, and why he invented. In this groundbreaking book, W. Bernard Carlson demystifies the legendary inventor, placing him within the cultural and technological context of his time, and focusing on his inventions themselves as well as the creation and maintenance of his celebrity. Drawing on original documents from Tesla's private and public life, Carlson shows how he was an idealist inventor who sought the perfect experimental realization of a great idea or principle, and who skillfully sold his inventions to the public through mythmaking and illusion.This major biography sheds new light on Tesla's visionary approach to invention and the business strategies behind his most important technological breakthroughs.

    The Apollo 11 mission that carried him and his two fellow astronauts on their epic journey marked the successful culmination of a quest that, ironically, had begun in Nazi Germany thirty years before. This is the story of the Apollo 11 mission and the 'space hardware' that made it all possible. Author Chris Riley looks at the evolution and design of the mighty Saturn V rocket, the Command and Service Modules, and the Lunar Module. He also describes the space suits worn by the crew, with their special life support systems. Launch procedures are described, 'flying' the Saturn V, navigation, course correction 'burns', orbital rendezvous techniques, flying the LEM, moon landing, moon walk, take-off from the moon, and earth re-entry procedure. Includes performance data, fuels, biographies of Armstrong, Aldrin and Collins, Gene Kranz and Werner von Braun. Detailed appendices cover all of the Apollo missions, with full details of crews, spacecraft names and logos, mission priorities, moon landing sites, and the Lunar Rover.

    It is presented in a full-color design, which allows students to read circuit diagrams and other important visuals easily.

    At the same time, Steve Jobs was being forced out of his beloved Apple and starting over with a new company, NeXT Computer. His goal was to build a supercomputer with the power to transform education. Menuez had found his story: he proposed to photograph Jobs and his extraordinary team as they built this new computer, from conception to product launch. In an amazing act of trust, Jobs granted Menuez unlimited access to the company, and, for the next three years, Menuez was able to get on film the spirit and substance of innovation through the day-to-day actions of the world’s top technology guru. From there, the project expanded to include the most trailblazing companies in Silicon Valley, all of which granted Menuez the same complete access that Jobs had. Menuez photographed behind the scenes with John Warnock at Adobe, John Sculley at Apple, Bill Gates at Microsoft, John Doerr at Kleiner Perkins, Bill Joy at Sun Microsystems, Gordon Moore and Andy Grove at Intel, Marc Andreessen at Netscape, and more than seventy other leading companies and innovators. It would be fifteen years before Menuez stopped taking pictures, just as the dotcom bubble burst. An extraordinary era was coming to its close. With his singular behind-the-scenes access to these notoriously insular companies, Menuez was present for moments of heartbreaking failure and unexpected success, moments that made history, and moments that revealed the everyday lives of the individuals who made it happen. This period of rapid, radical change would affect almost every aspect of our culture and our lives in ways both large and small and would also create more jobs and wealth than any other time in human history. And Doug Menuez was there, a witness to a revolution. In more than a hundred photographs and accompanying commentary, Fearless Genius captures the human face of innovation and shows what it takes to transform powerful ideas into reality.

    Arguing that the processes creating the technium are akin to those of biological evolution, Kelly devotes the opening sections of his exposition to that analogy, maintaining that the technium exhibits a similar tendency toward self-organizing complexity. Having defined the technium, Kelly addresses its discontents, as expressed by the Unabomber (although Kelly admits to trepidation in taking seriously the antitechnology screeds of a murderer) and then as lived by the allegedly technophobic Amish. From his observations and discussions with some Amish people, Kelly extracts some precepts of their attitudes toward gadgets, suggesting folk in the secular world can benefit from the Amish approach of treating tools as servants of self and society rather than as out-of-control masters. Exploring ramifications of technology on human welfare and achievement, Kelly arrives at an optimistic outlook that will interest many, coming, as it does, from the former editor of Wired magazine."Gilbert Taylor, Booklist

    The ability to duplicate that process in a lab, once thought impossible, may now be closer than we think. Today, teams of scientists around the world are being assembled by the boldest entrepreneurs, big business, and governments to solve what is the most difficult technological challenge humanity has ever faced: building the equivalent of a star on earth. If their plans to capture star power are successful, they will unlock thousands, potentially millions, of years of clean, carbon-free energy. Not only would controlled nuclear fusion help solve the climate crisis, it could also make other highly desired technological ambitions possible—like journeying to the stars. Given the rising alarm over deterioration of the environment, and the strides being made in laser and magnetic field technology, powerful momentum is gathering behind fusion and the possibilities it offers. In The Star Builders, award-winning young plasma physicist Arthur Turrell “offers an optimistic outlook for the future of fusion power and is adamant about the need to invest in it” (The New York Times). Turrell describes fascinating star machines with ten times as many parts as the NASA Space Shuttle, and structures that extend over 400 acres in an accessible and entertaining account, spotlighting the individuals, firms, and institutions racing for the finish line: science-minded entrepreneurs like Jeff Bezos and Peter Thiel, companies like Goldman Sachs and Google, universities like Oxford and MIT, and virtually every rich nation. It’s an exciting and game-changing international quest that will make all of us winners.

    Why is glass see-through? What makes elastic stretchy? Why does a paper clip bend? Why does any material look and behave the way it does? These are the sorts of questions that Mark Miodownik a globally-renowned materials scientist has spent his life exploring In this book he examines the materials he encounters in a typical morning, from the steel in his razor and the graphite in his pencil to the foam in his sneakers and the concrete in a nearby skyscraper.

     Christopher McKinlay has been featured in Wired Magazine for his groundbreaking analysis of OkCupid. For the first time he’s showing non-experts how to turn Internet dating on its head. This concise guide will show anyone (straight, gay, male or female) the procedure McKinlay used to meet his fiancee and how the same ideas can transform their lives and bring them from browsing to contact. One summer evening while logged into a supercomputer in Colorado waiting for a large computation, McKinlay was killing time on OkC when he was troubled by a problem: what if large groups of people responded to OkCupid’s personality questionnaire in statistically similar ways? He created custom software to scrape data from the site, collecting over 6,000,000 answers to OkC’s “match questions” from more than 20,000 real users. This data made clear he’d been using the site the wrong way. Based on his findings, McKinlay (a mathematics PhD), optimized his own profile. The transformation was profound. He went from showing a “match percentage” of 90% with a few hundred women in the L.A. area to showing 90% or higher with over 30,000 local women. Unsolicited messages from attractive strangers began flooding his inbox. With a foreword by Jon Finkel, McKinlay’s insightful how-to will teach you how to benefit from the buried statistical patterns of online romance.
