How does a pansy, for example, select the ingredients from soil to get the right colors for the flower? Now there's a great miracle. I think there's a supreme power behind all of this. I see it in nature.

I think there's a supreme power behind the whole thing, an intelligence. Look at all of the instincts of nature, both animals and plants, the very ingenious ways they survive. If you cut yourself, you don't have to think about it.

I realized that I would have some very tough sledding, and I was very discouraged because I didn't see much hope of getting into the field I wanted to get into with no college education.

That's the way I got along in life. I don't ever remember being particularly jealous of anybody, because I figured if I can't do it myself, I don't deserve to get it.

I used to think about how nice it would be to visit the planets. Of course, I didn't expect to see in my lifetime what has happened. I knew it would happen some day, but it came along faster than I at first thought.

You have to have hope. Otherwise, I don't think you could handle it. Of course, you have to have both luck and pluck to make it.

Young man, I am afraid you are wasting your time. If there were any more planets they would have been found long before this.
