How long since you used the pythagorean theory?
Not long… I use it when doing a variety of things. Like cabinet making, doors or door frames, etc. Heck I’ve even used it to make money from an officer while I was in the Navy when he told me I needed to use calculus to calculate something, because the answer couldn’t be figured out any other way. (Officers are sometimes so f*cking brilliant that they’re just plain stupid. It was like taking candy from a baby, and I thoroughly enjoyed spending his money at our next port call).
