Off-topic, somewhat.

Seeing all the fractions in the pizza video reminded me of my father. He worked over 25 years in a road construction machine factory. He could look at a bolt head or a nut and say what size it was. He would get 8th's and 16th's right every time. He was also a part-time carpenter. He could glance at a tape-measure and do the same thing. He struggled with millimeters when it became common much later in his life.
