I am proud of the fact that I never invented weapons to kill.

I never did a day's work in my life, it was all fun.

A good idea is never lost. Even though its originator or possessor may die, it will someday be reborn in the mind of another.

Personally, I enjoy working about 18 hours a day. Besides the short catnaps I take each day, I average about four to five hours of sleep per night.

I do not believe any type of religion should ever be introduced into the public schools of the United States.

Most of the exercise I get is from standing and walking around laboratory tables all day. I derive more benefit and entertainment from this than some of my friends and competitors get from playing games like golf.

If we did all the things we are capable of doing, we would literally astound ourselves.
