Measuring Guages
“When it takes a hair to be precise, the "tenth in a row" this measurement is well beyond what can be estimated by the most exercised eye.
And when the compass multiplies its talent, it captures the shade of a hundredth of a millimetre displayed by a reference arrow. This instrument is a measuring tool because it requires all the skill of a hand exercised to handle it.Watchmaker, clockmaker, jeweller, each trade has its "precision", adapted to the most frequent use which is to say the thickness of the material, bottom to top or from tooth to tooth.
It is a tool whose use can transform the material ... without acting directly on it.
It is a masterly tool, certainly, but even more a tool of a master to control the work of others.”
