最好的歌曲来自于真实的情感和经历。

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

Every discovery in science is built upon the work of countless others before us.

证明是一种可重复的说服实验。

你必须愿意失败，愿意犯错，愿意带着学到的教训重新开始。
