The world needs science, and science needs the world.

技术可以放大优秀教学的效果，但无法替代糟糕的教学。

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.

"The truth is that literature is the only way to overcome death."

在这个喧嚣的世界里，一本书可以是一个安静的角落。

继续前进。
