數(shù)學(xué)是理性的音樂。
In a world filled with hate, we must still dare to hope. In a world filled with anger, we must still dare to comfort. In a world filled with despair, we must still dare to dream. And in a world filled with distrust, we must still dare to believe.
經(jīng)常要坦白地承認(rèn)一項過失錯誤,這將使你的上司意料防備不及,才會給你一個機會去犯更多的錯誤。
