DavidR8’s post reminded me of my own father...he only finished high school, and somehow became a machinist at Hickham field in Hawaii and eventually a toolmaker. I remember him teaching me logarithms using tables, and how to extract square roots by hand when I was in 6th grade. I suppose all good machinists in those days needed to know some of these things, but I am impressed with his ability to use and explain them. They say you don’t understand something until you try to teach it to another.
