"La memoria es el hilo que teje la historia de los pueblos, sin ella estaríamos condenados a repetir los mismos errores."

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.

译文：能写文章的人，善于引用名言，虽只寥寥数语，却起到了画龙点睛的作用，使文章读起来更加优美、更加动人。

未来属于那些今天为之准备的人。
