I mean, it's simple enough to get an accurate flat surface but getting it flat and to a particular thickness is another matter when starting in a primitive metrological condition. I wonder when optical comparators came into use...What I find most fascinating about the really big metrology labs is the effort put into thermostats. They say that whoever has the best thermostat wins and some of those hvac systems are really, really cool.
