Science, like art, is not a copy of nature but a re-creation of her.

The progress of science is the discovery at each step of a new order which gives unity to what had seemed unlike.

In the moment of appreciation we live again the moment when the creator saw and held the hidden likeness.

The air in a man's lungs 10,000,000,000, 000,000,000,000 atoms, so that sooner or later every one of us breathes an atom that has been breathed before by anyone you can think of who has ever lived - Michelangelo or George Washington or Moses.

Fifty years from now if an understanding of man's origins, his evolution, his history, his progress is not in the common place of the school books we shall not exist.

We are a scientific civilization. That means a civilization in which knowledge and its integrity are crucial. Science is only a Latin word for knowledge ... Knowledge is our destiny.

Revolutions are not made by fate but by men.
