Ah yes, because plumbers, electricians, and brick layers never have to deal with geometry. That being said, none of my geometry education was taught with a practical motivation. But that being said, I was in the advanced track classes, so none of us were becoming professional carpenters. I’m actually probably one of the most “hands-on” people from that class, both in my job and in my life. I build scientific instruments and enjoy fixing things around the house.
