'Harpo Speaks' (Harpo Marx), and also perhaps 'Surely You're Joking, Mr. Feynman!' (Richard Feynman)

I remember distinctly the moment it occurred to me that calculus is the universal math language. It was during the ACT test--I'd just finished a calc class and solved a trig problem using calc. Oops, but wait a minute, I got the same answer using trig! You can use calc for any math problem. Nice.

I always hated that punk.

Thanks for that, John. It's really so appreciated!
