The Dawn of the Drone
“[A] slice of largely-forgotten military history . . . a fascinating exploration of some magnificent men and their flying machines.” —The Sunday Post In the dark days of World War I, when flying machines, radio, and electronics were infant technologies, the first remotely controlled experimental aircraft took to the skies and unmanned radio controlled 40-foot high-speed Motor Torpedo Boats ploughed the seas in Britain. Developed by the British Army’s Royal Flying Corps and the Royal Navy these prototype weapons stemmed from an early form of television demonstrated before the war by Prof. A. M. Low. The remotecontrol systems for these aircraft and boats were invented at RFC Secret Experimental Works commanded by Prof. Low, which was part of the organization of “back-room boys” in the Munitions Inventions Department. These audacious projects led to the hundreds of remotely controlled Queen Bee aerial targets in the 1930s and hence to all the machines that we now call “drones.” Starting well before WWI and, for the lucky ones, extending well beyond it, the lives of Archibald Low and many of his contemporaries were extraordinary as were the times they lived through. They were around for the first epic aircraft flights and with the aid of the very technologies that had enabled the development of drones, they saw air travel transformed from the precarious to the routine. It is astonishing that the origins of the first drones are not common knowledge in Britain and that the achievement of these maverick inventors is not commemorated. “A focused and engaging look at one arena of behind-the-scenes scientific research and the larger-than-life personalities who populated it.” —Booklist

One Good Turn
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.
