Creative energy is more critical than learning.

Joy and amazement of the beauty and grandeur of this world of which man can just form a faint notion.

Make everything as simple as possible, but not simpler. A man should look for what is, and not for what he thinks should be. We cannot solve our problems with the same thinking we used when we created them. A question that sometimes drives me hazy: am I or are the others crazy? Any intelligent fool can make things bigger and more complex... It takes a touch of genius - and a lot of courage to move in the opposite direction. All religions, arts and sciences are branches of the same tree. It's not that I'm so smart, it's just that I stay with problems longer.

Nature conceals her secrets because she is sublime, not because she is a trickster.

If you can't explain something simply, you don't know enough about it.

Am I, or the others crazy?

The more I study science, the more I believe in God.
