Matching Quote
"... fain would I turn back the clock and devote to French or some other language the hours I spent upon algebra, geometry, and trigonometry, of which not one principle remains with me. Stay! There is one theorem painfully drummed into my head which seems to have inhabited some corner of my brain since that early time: "The square on the hypotenuse of a rightangled triangle is equal to the sum of the squares on the other two sides!" There it sticks, but what of it, ye gods, what of it?"
