"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 Victorian Glasgow, from weapons design in the Italian Renaissance 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. The screwdriver, perhaps the last hand tool in a world gone cyber, represents nothing less than the triumph of precision. "--BOOK JACKET.
