There's something to be said for relatives...it has to be said because it's unprintable!

You teach me baseball and I'll teach you relativity...No we must not. You will learn about relativity faster than I learn baseball.

Education is what is left after you've forgotten everything you've learned.

It takes a touch of genius - and a lot of courage to move in the opposite direction.

The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity.

Some men spend a lifetime in an attempt to comprehend the complexities of women. Others pre-occupy themselves with somewhat simpler tasks, such as understanding the theory of relativity!

I shall never believe that God plays dice with the world.
