    A seven-million-year journey to the very origins of the human lineage, First Steps shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities, our thirst for exploration, our use of language–and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. First Steps examines how walking upright helped us rise above all over species on this planet.First Steps includes an eight-page color photo insert.

    This seminal work is reproduced here for a whole new generation to enjoy. In Sagan's typically lucid and lyrical style, he discusses many topics from astrophysics and solar system science, to colonization, terraforming and the search for extraterrestrials. Sagan conveys his own excitement and wonder, and relates the revelations of astronomy to the most profound human problems and concerns: issues that are just as valid today as they were thirty years ago. New to this edition are Freeman Dyson's comments on Sagan's vision and the importance of the work, Ann Druyan's assessment of Sagan's cultural significance as a champion of science, and David Morrison's discussion of the advances made since 1973 and what became of Sagan's predictions. Who knows what wonders this third millennium will reveal, but one thing is certain: Carl Sagan played a unique role in preparing us for them.

    In those heady early days of computing, Britannia very much ruled the digital waves.Electronic Dreams looks back at how Britain embraced the home computer, and at the people who drove the boom: entrepreneurs such as Clive Sinclair and Alan Sugar seeking new markets; politicians proclaiming economic miracles; bedroom programmers with an unhealthy fascination with technology; and millions of everyday folk who bought into the electronic dream and let the computer into their lives. It is a history of home computers such as the Commodore VIC20, BBC Micro, and ZX Spectrum; classic computer games like Manic Miner and Elite; the early information networks that first put the home online; and the transformation of the computer into an everyday object in the British home.Based on interviews with key individuals, archive sources, and study of vintage hardware and software, and with a particular focus on the computer's place in social history, Electronic Dreams is a nostalgic look at how a depressed 1980s Britain got over its fear of microchips and embraced the computer as a “passport to the future.”

    Priestley represented a unique synthesis: by the 1780s, he had established himself as one of the world's most celebrated scientists, most prominent religious figures, and most outspoken political thinkers. Yet he would also have become one of the most hated men in all of his native England. When an angry mob burned down his house in Birmingham, Priestley and his family set sail for Pennsylvania.In the nascent United States, Priestley hoped to find the freedom to bridge the disciplines that had governed his life, to find a quiet lab and a receptive pulpit. Once he arrived, as a result of his close relationships with the Founding Fathers—Jefferson credited Priestley as the man who prevented him from abandoning Christianity—Priestley found himself at the center of what would go down as one of the seminal debates in American history. And as Johnson brilliant charts, Priestley exerted profound if little-known influence on the shape and course of this great experiment in nation-building.As in his most recent bestselling work, The Ghost Map, Steven Johnson here uses a dramatic historical story to explore themes that have long engaged him: innovation and the way new ideas emerge and spread, and the environments that foster these breakthroughs. As he did in Everything Bad is Good for You, he upsets some fundamental assumptions about the world we live in—namely, what it means when we invoke the Founding Fathers—and replaces them with a clear-eyed, eloquent assessment of where we stand today.
