How do I work? I grope.

The most precious things in life are not those you get for money.

I don't believe in mathematics.

The process of scientific discovery is, in effect, a continual flight from wonder.

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

e idea of a personal God is quite alien to me and seems even naive. However, I am also not a "Freethinker" in the usual sense of the word because I find that this is in the main an attitude nourished exclusively by an opposition against naive superstition. My feeling is insofar religious as I am imbued with the consciousness of the insuffiency of the human mind to understand deeply the harmony of the Universe which we try to formulate as "laws of nature." It is this consciousness and humility I miss in the Freethinker mentality. Sincerely yours, Albert Einstein.

It is just as important to make knowledge live and keep it alive as to solve specific problems.
