Traces the history of the screwdriver from a sketch in da Vinci's pad to a later patent and mass production.
About this book
The Best Tool of the Millennium The seeds of Rybczynski's elegant and illuminating new book were sown by The New York Times, whose editors asked him to write an essay identifying "the best tool of the millennium." An award-winning author who once built a house using only hand tools, Rybczynski has intimate knowledge of the toolbox -- both its contents and its history -- which serves him beautifully on his quest. One Good Turn is a story starring Archimedes, who invented the water screw and introduced the helix, and Leonardo, who sketched a machine for carving wood screws. It is a story of mechanical discovery and genius that takes readers from ancient Greece to car design in the age of American industry. Rybczynski writes an ode to the screw, without which there would be no telescope, no microscope -- in short, no enlightenment science. One of our finest cultural and architectural historians, Rybczynski renders a graceful, original, and engaging portrait of the tool that changed the course of civilization.

About this book
Albert Einstein's groundbreaking scientific discoveries made possible the creation of the most terrible weapon the world had ever known. But he made another discovery that he chose to reveal to no one—to keep from human hands a power that dwarfed the atomic bomb. When twelve-year-old Daphne Marrity takes a videotape labeled Pee-wee's Big Adventure from her recently deceased grandmother's house, neither she nor her college-professor father, Frank, realize what they now have in their possession. In an instant they are thrust into the center of a world-altering conspiracy, drawing the dangerous attentions of both the Israeli Secret Service and an ancient European cabal of occultists. Now father and daughter have three days to learn the rules of a terrifying magical chess game in order to escape a fate more profound than death—because the Marritys hold the key to the ultimate destruction of not only what's to come . . . but what already has been.

Finally, a robots book for people who don't know the first thing about robotics! Absolute Beginner's Guide to Robots is well-written, inviting, and action-packed, with engaging ideas and fascinating factoids about robots and robot-related arts and sciences. You are led gently into the intimidating world of robotics, but nearly 400 pages later, you emerge with a respectable knowledge of robot history, the major fields and "schools" of robotics today, and the basic skills and resources needed to create hobby robots. By the end of the book, you will be the proud owner of three bots, the first two of which demonstrate key robotic principles. The third is a programmable/expandable robot, which serves as a platform for future experimentation. And best of all, these robots are built with simple to get and inexpensive parts - many of which you already have around the house!
