The Parasite of Physics

My father's a physicist and he was one of those people. If I would ask a question like, you know, why is the sky blue? He's naturally actually taking a piece of paper and doing X and Y on it. And then he would draw things and show, don't forget a square. Well, as Clint Eastwood says to Hal Holbrook, in Magnum Force, a man's got to know his limitations breaks. The only old level exam that you failed and you failed abysmally was physics. Yes. But when you got the math, the geometry is something you never, never liked - which I was surprised about.
