People see the wrongness in an idea much quicker that the rightness.

We have a lot of people revolutionizing the world because they've never had to present a working model.

My definition of an educated man is the fellow who knows the right thing to do at the time it has to be done. You can be sincere and still be stupid.

If you're doing something the same way you have been doing it for ten years, the chances are you are doing it wrong.

Keep on going and the chances are you will stumble on something, perhaps when you are least expecting it. I have never heard of anyone stumbling on something sitting down.

It is man's destiny to ponder on the riddle of existence and, as a byproduct of his wonderment, to create a new life on this earth.

Research is industrial prospecting. The oil prospectors use every scientific means to find new paying wells. Oil is found by each one of a number of methods. My own group of men are prospecting in a different field, using every possible scientific means. We believe there are still things left to be discovered. We have only stumbled upon a few barrels of physical laws from the great pool of knowledge. Some day we are going to hit a gusher.
