智慧属于对永恒事物的智性理解；知识则属于对临时事物的理性理解。

"A man's memory might have only a hundred clear days in it and he has lived thousands."

"Science is not only a disciple of reason but, also, one of romance and passion."

Be the change you wish to see in the world.

Anyone who keeps the ability to see beauty never grows old.

韧性不仅仅是恢复，更是向前迈进。
