Our imagination is the only limit to what we can hope to have in the future.

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.

Don't bring anything to me but trouble.

We need to teach the highly educated man that it is not a disgrace to fail and that he must analyze every failure to find its cause. He must learn how to fail intelligently, for failing is one of the greatest arts in the world.

The typical eye sees the ten per cent bad of an idea and overlooks the ninety per cent good.

I am not interested in the past. I am interested in the future, for that is where I expect to spend the rest of my life.

I've never heard of anyone stumbling on something sitting down.
