A quote from John Horton Conway in today’s MathBlab:
You know, people think mathematics is complicated. Mathematics is the simple bit. It’s the stuff we can understand. It’s cats that are complicated. I mean, what is it in those little molecules and stuff that make one cat behave differently than another, or that make a cat? And how do you define a cat? I have no idea.
