"Mathematics is the music of reason."
"The most powerful tool in computer science is not the computer itself, but the human mind."
一部好戏应该让人不安,而非舒适。
动口不如动手去干,求人不如自己亲自去办。
The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as in poetry.
如果你知道如何使用它,电脑是一个奇妙的工具。
