If we were to start today on an organized and well-supported space program I believe a practical passenger rocket can be built and tested within ten years.

My experiences with science led me to God. They challenge science to prove the existence of God. But must we really light a candle to see the sun?

I have learned to use the word 'impossible' with the greatest caution.

Science does not have a moral dimension. It is like a knife. If you give it to a surgeon or a murderer, each will use it differently.

Basic research is what I am doing when I don't know what I am doing.

It was very successful, but it fell on the wrong planet.

I always entertain great hopes.

Love doesn't grow on the trees like apples in Eden - it's something you have to make and you must use your imagination to make it too just like anything else. It's all work work.

If the Americans go in and overthrow Saddam Hussein and it's clean, he has nothing, I will apologize to the nation, and I will not trust the Bush administration again.

The harder you tried not to think, the more you thought.

Just put your best foot forward and hope for the best. You also have to acknowledge that you're going to make mistakes.

Incivility is not a Vice of the Soul, but the effect of several Vices; of Vanity, Ignorance of Duty, Laziness, Stupidity, Distraction, Contempt of others, and Jealousy.

We rode on the winds of the rising storm, We ran to the sounds of the thunder. We danced among the lightning bolts, and tore the world asunder.

You can do a million different funks from a million different people and you'll never get anything exactly alike - that's what's so beautiful about it.
