Science really creates wealth and opportunity which did not exist before. Whereas the old order was based on competition, the new order of science makes possible, for the first time, a cooperative creative effort in which every one is the gainer and no one the loser ...

The stumbling way in which even the ablest of the scientists in every generation have had to fight through thickets of erroneous observations, misleading generalizations, inadequate formulation, and unconscious prejudice is rarely appreciated by those who obtain their scientific knowledge from textbooks.

Good science is almost always so very simple. After it has been done by someone else, of course.

In science the credit goes to the man who convinces the world, not to the man to whom the idea first occurred.

Not only will atomic power be released, but someday we will harness the rise and fall of the tides and imprison the rays of the sun.

There will one day spring from the brain of science a machine or force so fearful in its potentialities, so absolutely terrifying that even man, the fighter, who will dare torture and death in order to inflict torture and death, will be appalled, and so abandon war forever. What man's mind can create, man's character can control.

Concern for man himself and his fate must always form the chief interest of all technical endeavors, concern for the great unsolved problems of the organization of labor and the distribution of goods-in order that the creations of our mind shall be a blessing and not a curse to mankind. Never forget this in the midst of your diagrams and equations.

Science can only ascertain what is, but not what should be, and outside of its domain value judgments of all kinds remain necessary.

The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses.

The scientist finds his reward in what Henri Poincare calls the joy of comprehension, and not in the possibilities of application to which any discovery may lead.
