Why Is There Fun

Linus Torvalds 在他的书Just for Fun中谈到The Beauty of programming:

It’s a game much more involved than chess, a game where you can make up your own rules and where the end result is whatever you can make of it.

这与数学有着相似之处，同样是在人所创造的系统中玩耍

One of the biggest joys was learning that computers are like mathematics: You get to make up your own world with its own rules. In physics, you’re constrained by existing rules. But in math, as in programming, anything goes as long as it’s self-consistent.
