科学应该始终为人类服务，而不是反过来。
No one's actions can be completely understood unless they are seen in the context of that person's life as a whole.
El arte de escribir consiste en encontrar la belleza en lo ordinario.
唤醒天才的是困难。
"Science is not just a profession; it's a passion that drives us to explore the unknown."
【译文】力气单薄就不要去背负重物，说话没分量就不要规劝别人。没有钱就不要到人群中去，遇到危难千万别去求亲戚。
