very amazingly written.
goes from the age of industrial revolution, to Ford and Rolls Royce(the author thinks that it shoud be Royce Rolls) to jet engines, ( there is a very interesting part about a self-cooling blade full of holes that is nessesary for the engines to work ) and then does to these japanese watch craftsmen that delight in bot precision and the hang-maded-ness.

Pleasant, meandering recounting of the history of precision.
Fascinating look at the history of precision engineering and its effects on the inventions that have shaped our world.
Precision is the key …
I thoroughly enjoyed this book. The book starts with Mr Winchester’s description of the gauge blocks his father brought home, and then takes us through the history of precision engineering. I revisited the history of John Harrison’s invention of the chronometer, James Watt’s invention of the steam engine, learned about John ‘Iron Mad’ Wilkinson’s skills and was reminded that precision engineering has replaced some skilled work as many machines can be operated by unskilled workers.
Mr Winchester makes a case for the birth of precision engineering in the 19th century. Steam engines, cars, other manufactured mechanisms. Mass production replacing skilled craftsman. But with greater precision comes risk: the slight misalignment of a tiny tube in a jet engine almost resulted in a fatal catastrophe (November 2010), and incorrect grinding of the main mirror of the Hubble telescope required a servicing mission in 1993. The more precise the engineering, the less permissible the variation that can be accepted. Where will it end? I admire the skills and the increasingly precise measurements but wonder how far we need (as distinct from want) to pursue precision. Just how much further can we go in the Silicon Age?
And, amongst the stories of technological advances, I was delighted to read about handmade Seiko watches.

Book Review
The Perfectionists
Simon Winchester
5/5 stars
The exactitude that allows the modern world to function
*******
All three are brilliant: the book's setup, the author, and the topic.
Simon Winchester has written a slew of best-selling books around unrelated topics; in addition to being a best-selling author/journalist, he has worn other unexpected hats before. (Field geologist, journalist / newspaper correspondent.)
Essentially, Winchester centers each of his 10 chapters around a different degree of tolerance-- the 1st chapter being the history of machines that function within a tolerance of 0.1 inches and the 9th chapter being microchips that function within tolerances near the Heisenberg limit (10^-34).
He dredges up all of the forgotten flesh and blood human beings that had to take risks in order to bring new technology to market and the geniuses that had the insights about things that we now take for granted.
Of the book:
10 chapters + prologue/afterword
308 pages of prose= x(bar) 30.8/per.
EXCELLENT glossary.
Chapters:
Prologue. Accuracy versus precision.
1. Mechanical clocks, sailing devices, cannons and steam engines. The beginning of precision was with John "Iron Mad Wilkinson.
2. Locksmiths and their unbreakable locks. Joseph Bramah. The learning of making IDENTICAL block systems was a further progress in quality control. It made the British Navy victorious over Napoleon. The mechanizing of manufacturing also put huge numbers of craftsmen out of work. (Luddites!)
3. Gun technology. Muskets were a joke. 18th century rifle was better but suffered from the problem of non-interchangeability. Americans did not initially solve that problem, but they were the first to scale it up. "Connecticut clocks" were once upon a time a thing, as clocks were a symbol of entry into the middle class.
4. Joseph Whitworth took the trouble to learn how to standardize screws / bolts. (No one had thought of that before, but it certainly turned out to be handy when it was discovered.) The farsighted leadership of Prince Albert in 1851 created the Great Exhibition, which was a reaction/ meeting space for the greatest technology of the day.
5. Henry Royce, the engineering genius. And his improvement of existing cars to make Rolls-Royce. Henry Ford, the production genius. (Absolute trade off between precision and craftsmanship.)
6. Frank Whittle conceived of the first turbine, and it took lots of trial and error to make something operate that works at unimaginably high pressures and temperatures.
7. A venture into the extremely complicated world of Optics. The Hubble telescope was meant to be designed to tolerances within 1 millionth of an inch. And it happened that lenses being off by 1/50th the width of a human hair was enough to (almost) ruin Hubble. Getting Hubble into space was a feat of engineering prowess, but it was an even bigger one set up the corrective Optics. (They had astronauts practice and do dry runs for 11 months.)
8. GPS is the Doppler effect on steroids, and it started out being able to measure to within distances almost anywhere on the planet of a couple of hundred feet, and that is now down to within distances of a six inches. (There are other, state-owned, systems: US Navstar GPS; Russian GLONASS; Pan-European Galileo; Chinese Beidou; Japanese QZSS; Indian IRNSS.)
9. The seed person of Silicon valley is the one that people want to forget. William Shockley, the Eugenicist. Also, selected thoughts on the construction and future direction of chips.
10. Brief exposition of Japanese timekeeping as well as meditations on the trade off between precision and craftsmanship.
Afterword. Derivations of the various units/fundamental units. Exposition of the trial and error nature of the process.
Second order thoughts:
1. With a nod to the Marxists: it has been said a million times before and thought countless number of times that every firm is sitting in existence and only waiting for workers to come and get it started. But, as shown by the many engineering projects here.... The brain power comes first and the workers to execute the idea come second.
2. Rolls-Royce is an excellent example of the extreme end of a dichotomy: a car company (or any other) that makes (unaffordable) goods that are engineered to the highest level of craftsmanship will actually be less profitable than a car company that makes automated affordable junk. (I don't think Ford has been taken over by anybody, and their cars were crap until just about 20 years ago. Meanwhile, Rolls-Royce turned car making into rocket science and they have been bought and sold many times.)
Mass production or craftsmanship? Pick one or the other.
3. Engineering is the very antithesis of philosophy, and engineering knowledge precedes by subtraction. Interchangeability is at the heart of all modern mass production methods, which is underpinned by precision / tolerance. It took a lot of bitter experience to figure that out.
4. War is a great promoter/accelerant of technology. And this is not the first book in which that theme has shown up. (Simon Singh showed it as a recurring feature in "The Code Book." Niall Ferguson showed the development of financial instruments--"The Ascent of Money"-- primarily to fight wars against other kingdoms.)
5. When governments outsource things to contractors, they automatically pick the lowest-priced contractor (in ignorant defiance of the Law of Common Business Balance) and they get exactly what they pay for. They saved $35 million on the lens-grinding for the $1.5 billion piece of Hubble equipment. And they ended up spending way more than that on Corrective Optics Space Telescope Axial Replacement. (COSTAR).
6. There may be an absolute limit to the amount that human beings can be precise.
7. The bizarre/arbitrary metric system is something that came out of the French revolution, and is only a subset of the changes that they wanted to make. (The week was supposed to be 10 days long; the day 10 hours long; each minute 100 seconds; each second 100 minutes.) The meter itself is meant to be 140 millionth of the length of the meridian of the Earth.
A lot of people like to pretend that the SI system is "logical," but in reality there was lots of trial and error deciding what it would be. (It was not immediately apparent.)
8. History is such a whimsical thing. Japanese people appropriated the Chinese writing system (in some sense), and yet they have a sense of craftsmanship that China has never had in its long history. (A lot of Chinese paper making arts have been lost in China proper and preserved by Japan.) China did not even have a standardized unit of time until the Jesuits came along and set one up for them.
Great quote: "The distance in miles of 4.3 light years is 26 trillion miles. It is now known with absolute certainty that the cylindrical masses on ligo can help to measure that vast distance to within the width of a single human hair." (p.306)
Verdict: Strongly recommended. there's so many bits of information, that no human being could be expected to remember them all. But even just to remember 10% of what is here is to know a great deal. The Afterword makes the book worth a new purchase in its own right.

I listened to this on audiobook, narrated by the author, and I’m really glad I did. I would have enjoyed this no matter what, but this is clearly a topic that the author loved writing about, and the narration is suffused with that enthusiasm. As enthusiastic as a book about precision engineering can be, of course - it’s a stately, restrained enthusiasm.
This book was surprisingly good, to me. To someone who is non-technical and not interested in the technical history of precision machinery, it might be mostly boring. There is probably something here for everyone, though, such as the story of the Hubble telescope and its rescue from total failure after being launched into orbit.
The story starts out with the author recounting an experience when he was young, and his father brought out a heavy oak box with a brass tag on the outside. Inside were about a hundred metal tiles of various sizes, with numeric labels. These tiles were so precisely flat that when one was placed on top of another, they could not be pulled apart, only slid apart like strong magnets. They didn't even seem to be two objects, because the line where they joined was so precise that it looked like the two tiles were fused together. The tiles are used for measuring things to very tight tolerances. Engineers, and people like me see the beauty in something like this. His mother, on the other hand, was not too happy about these oily pieces of metal on her clean tablecloth.
The book goes on to tell all about things like rifles, steam engines, cannons, etc, back in the mid 19th century. Rifles were hand-made, and didn't have interchangeable parts. If a part broke, the rifle could not be used until it was returned to have a new part made for it. Cannons were made in a way that produced variations in the size of the bore, so cannon balls didn't always fit correctly. The author tells about the people who solved these problems, while explaining along the way how they worked and why problems arose. Along the way, men devised machines to help make the products, because machines could make things exactly the same every time. Craftsmen were insulted by this, but they couldn't really change it, because it was true.
I learned a lot from the book, as it explained steam engines, gasoline engines, Rolls-Royces and Fords, fountain pens and watches, jet engines, rockets, the development of the Hubble telescope, all the while showing how precision got more and more exact. It explains how standards were created and improved, how measuring units went from an inch that was the size of someone's thumb up to being a standard meter that was a fraction of the distance from the north pole to the equator along a particular meridian, how even that wasn't enough because it turned out to be off by 2/10ths of a millimeter, so they came up with a new standard, which was simply “the length equal to 1,650,763.73 wavelengths in vacuum of the radiation corresponding to the transition between the levels 2p10 and 5d5 of the krypton-86 atom.” I tried to calibrate my metric ruler, but gave up pretty quickly.
Even the lowly second has been calibrated using an atomic clock that's so accurate that it would neither lose nor gain a second in 138 million years. Wind it once, and you're done.
After all this talk about super precision, there was a chapter on Japan, and their fondness for both precision and ancient hand-made imprecision. He included a visit to the Seiko factory which at one time had the most accurate timepieces in the world based on their quartz crystal technology. They make some very high precision watches. When the author offered to trade his special Rolex for a Seiko, they laughed and declined. Not far away is a place famous for its hand-hammered metallic teapots, etc, that are considered equally valuable to the people around there.

slow-paced
Well researched and clearly presented set of chapters about the progression of precision through history. Some of the chapters seem only a bit loosely connected, but they are all interesting and well written, with the occasional personal anecdote added in. Good bibliography and a glossary.
