Anyone who cannot cope with mathematics is not fully human.
At best he is a tolerable subhuman who has learned to wear
shoes, bathe, and not make messes in the house.
LAZARUS LONG
“The three-legged stool of understanding is held up by history, languages, and mathematics. Equipped with these three you can learn anything you want to learn. But if you lack any one of them you are just another ignorant peasant with dung on your boots.”
Another one of my favorite Heinlein quotes. And essentially true.
