Each year, it seems, larger and more daunting mountains of text rise from the lush lowlands of visual reproduction.

All of the books in the world contain no more information than is broadcast as video in a single large American city in a single year. Not all bits have equal value.

I find out what the world needs, then I proceed to invent. My main purpose in life is to make money so that I can afford to go on creating more inventions.

Someday man will harness the rise and fall of the tides, imprison the power of the sun, and release atomic power.

I believe that the science of chemistry alone almost proves the existence of an intelligent creator.

I never pick up an item without thinking of how I might improve it. I never perfected an invention that I did not think about in terms of the service it might give others. I want to save and advance human life, not destroy it. I am proud of the fact that I never invented weapons to kill. The dove is my emblem.
