"There are people who say, ‘I’ll never use this math, these trig identities’ from 10th or 11th grade, or maybe you never learned them.
Here’s the catch: whether or not you ever again use the math that you learned in school, the act of having learned the math established a wiring in your brain that didn’t exist before.
And it’s the wiring in your brain that makes you the problem solver… even if you don’t want to become a scientist, the minimum you should ask of yourself –demand of yourself– is that you become scientifically literate… and mathematically literate.
Because therein are the engines of problem solving in the world."
