Exactly: How Precision Engineers Created the Modern World

Simon Winchester


An engaging history of engineering through the the lens of ever-increasing precision. starting with more efficient steam engines and ending with spacecraft and microprocessors.

Until about two-thirds of the way through I had a criticism that the book focused on precision solely as a means to mass production the need to components that are exactly the same to facilitate easy replacement, as contrasted against craft-made items. I was contrasting this against one-off, hand-made, but nonetheless precise artefacts such as the turbulence experiment described by James Gleick in Chaos: Making a New Science: a tiny fluid chamber with embedded sensors, still regarded as one of the finest experiments ever crafted. But the discussions of watches more than remedied the omission.

The chapter on Japan as a contrast to the "cult" of precision feels a bit forced. Yes, the Japanese have a sensitivity (wabi sabi) for the imperfect in art while maintaining a reverence for high-precision machines – but so do other cultures and art forms, not least jazz and abstract impressionism, that render the contrast a bit superficial.
