PositiveThe Washington PostWinchester examines how a desire for precision has driven technological progress and often been a prerequisite for it ... Along the way, he tells stories about finely balanced Rolls Royce engines, Leica cameras and their prized lenses, and the Hubble Space Telescope, whose mirror was carefully ground to exactly the wrong shape, \'precisely imprecise,\' as he puts it ... The book’s gimmick of ordering chapters by degrees of precision is actually quite logical, because precision is necessary to achieve precision ... There is no way for a story on this subject to be comprehensive, because precision has been a pursuit of so many areas of manufacturing, science and technology. Winchester therefore has had to be selective.
