The joy of discovery in mathematics is like solving a puzzle that the universe has left for us.

不要轻易放弃，坚持到底就是胜利。

最好的数学不仅仅是逻辑的；它是直观和创造性的，将严谨与想象力结合在一起。

In science, the credit goes to the man who convinces the world, not to the man to whom the idea first occurs.

以这样奢侈的国君,去统治那些爱好奢侈的臣民,想要国家不动乱,是不可能的。

成功不在于从不犯错，而在于从不重蹈覆辙。
