所有老年人共同的大秘密是，在七八十年里你其实没有改变。你的身体变了，但你一点都没变。
The great secret that all old people share is that you really haven't changed in seventy or eighty years. Your body changes, but you don't change at all.
理性是感性的镜子。
A building should be rooted in its site, but reach for the sky.
Science without ethics is like a ship without a compass.
