科学没有国界，因为知识属于人类，是照亮世界的火炬。
Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.
"The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion."
Never stop learning, because the world never stops changing.
自知之明的人，不埋怨人；了解命运的人，不埋怨天；埋怨别人的人，遭遇穷困；埋怨上天的人，没有志向。
"There is a world of difference between the love we feel for a wild creature and the love we feel for a human being."
