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

Great spirits often meet violent oppisition with mediocre minds.

I hate crowds and making speeches. I hate facing cameras and having to answer to a crossfire of questions. Why popular fancy should seize upon me, a scientist, dealing in abstract things and happy if left alone, is a manifestation of mass psychology that is beyond me.

I am not more gifted than anybody else. I am just more curious than the average person and I will not give up a problem until I have found the proper solution.

I love to travel, but hate to arrive.

Thinking is hard work; that's why so few do it.

What is inconceivable about the universe is that it is at all conceivable.
