Bestselling author Simon Winchester writes a magnificent history of the pioneering engineers who developed precision machinery to allow us to see as far as the moon & as close as the Higgs boson. Precision is the key to everything. It is an integral, unchallenged & essential component of our modern social, mercantile, scientific, mechanical & intellectual landscapes. The items we value in our daily lives
- a camera, phone, computer, bicycle, car, a dishwasher perhaps
- all sport components that fit together with precision & operate with near perfection. We also assume that the more precise a device the better it is. & yet whilst we live lives peppered & larded with precision, we are not, when we come to think about it, entirely sure what precision is, or what it means. How & when did it begin to build the modern world? Simon Winchester seeks to answer these questions through stories of precision`s pioneers. Exactly takes us back to the origins of the Industrial Age, to Britain where he introduces the scientific minds that helped usher in modern production: John ` Iron-Mad` Wilkinson, Henry Maudslay, Joseph Bramah, Jesse Ramsden, & Joseph Whitworth. Thomas Jefferson exported their discoveries to the United States as manufacturing developed in the early twentieth century, with Britain`s Henry Royce developing the Rolls Royce & Henry Ford mass producing cars, Hattori`s Seiko & Leica lenses, to today`s cutting-edge developments from Europe, Asia & North America. As he introduces the minds & methods that have changed the modern world, Winchester explores fundamental questions. Why is precision important? What are the different tools we use to measure it? Who has invented & perfected it? Has the pursuit of the ultra-precise in so many facets of human life blinded us to other things of equal value, such as an appreciation for the age-old traditions of craftsmanship, art, & high culture? Are we missing something that reflects the world as it is, rather than the world as we think we would wish it to be? & can the precise & the natural co-exist in society?
