"Prime numbers are what is left when you have taken all the patterns away. I think prime numbers are like life. They are very logical but you could never work out the rules, even if you spent all your time thinking about them."
晏子春秋
山中有长得直的树,世上却没有直的人。
不是关于想法,而是关于实现想法。
煤炭推动了我们的过去,但我们必须诚实地面对它在未来中的作用。
