成为人类就是在世界中存在，而在世界中存在就是在时间中存在。
To be human is to be in the world, and to be in the world is to be in time.
The only fence against the world is a thorough knowledge of it.
The only way to deal with death is to transform everything that precedes it into art.
未来属于科学——属于那些敢于探索的人。
进步既需要远见，也需要执行力。
世界充满了符号，但我们常常太盲目而看不到它们。
