"The beauty of science lies in its ability to constantly evolve and challenge our understanding of the world."
科学的美丽在于它不断发展和挑战我们对世界的理解的能力。
我们不是从祖先那里继承了土地，而是从子孙那里借来的。
The test of our progress is not whether we add more to the abundance of those who have much; it is whether we provide enough for those who have too little.
If you are under the impression you have already perfected yourself， you will never rise to the heights you are no doubt capable of.
Leadership is about vision and responsibility, not power.
