1、把你的手放在滾熱的爐子上一分鐘，感覺起來像一小時。坐在一個漂亮姑娘身邊整整一小時，感覺起來像一分鐘。這就是相對論。Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's relativity.

3、只要我還能有所選擇，我就只想生活在這樣的國家裡，這個國家中所實行的是：公民、自由、寬容，以及在法律面前公民一律平等。公民自由意味著人們有用言語和文字表示其政治信念的自由；寬容意味著尊重別人的無論哪種可能有的信念。這些條件目前在德國都不存在。那些對國際諒解事業有特別重大貢獻的人，在那裡正受到迫害，其中就有一些是一流的藝術家。

原文：The physicists say that I am a mathematician, and the mathematicians say that I am a physicist. I am a completely isolated man and though everybody knows me, there are very few people who really know me.
6、那我只能對親愛的主表示遺憾。相對論是正確的。
原文：Then I would have felt sorry for the dear Lord. The theory is correct. - When asked by a student what he would have done if Sir Arthur Eddington's famous 1919 gravitational lensing experiment, which confirmed relativity, had instead disproved it.
7、一個聰明的笨蛋可以把事情做得更大，把事情做得更複雜，也更暴力。這個過程需要一點天才——很多的信念——只是朝著相反的方向。

8、一個人從未犯錯是因為他不曾嘗試新鮮事物。

9、當知識的圓周擴大之時，黑暗的圓周也一樣。
原文：As our circle of knowledge expands, so does the circumference of darkness surrounding it.
