We have merely scratched the surface of the store of knowledge which will come to us. I believe that we are now, a-tremble on the verge of vast discoveries - discoveries so wondrously important they will upset the present trend of human thought and start it along completely new lines .

I am both pleased but astonished by the fact that mankind has not yet begun to use all the means and devices that are available for destruction. I hope that such weapons are never manufactured in quantity.

I am a vegetarian as well as a passionate anti-alcoholic, because I can thus make better use of my brain.

I start where the last man left off.

Accomplishing something provides the only real satisfaction in life.

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 owe my success to the fact that I never had a clock in my workroom.
