But seriously, gauge blocks are fascinating; as are fine micrometers. Changes in temperature causing expansion drives home the inexactness of size. At certain scales it all becomes relative.
I used to work in this one factory where I had use to calipers for making sure parts were within specification, and they were digital calipers. Which are all fine and good, except the ones they had sucked. Really made me appreciate the value of a good, old-fashioned well-made analog caliper.
You fool, what have you done
