I believe that you can, by taking some simple and inexpensive measures, extend your life and your years of well-being. My most important recommendation is that you take vitamins every day in optimun amounts, to supplement the vitamins you receive in your food.

We may say that life has borrowed from inanimate processes the same basic mechanism used in producing those striking structures that are crystals, with their beautiful plane faces.

The power to destroy the world by the use of nuclear weapons is a power that cannot be used - we cannot accept the idea of such monstrous immorality.

I have always wanted to know as much as possible about the world.

I think every person should be able to enjoy life. Try to decide what you most enjoy doing, and then look around to see if there is a job for which you could prepare yourself that would enable you to continue having this sort of joy.

Science is the search for the truth--it is not a game in which one tries to beat his opponent, to do harm to others. We need to have the spirit of science in international affairs, to make the conduct of international affairs the effort to find the right solution, the just solution of international problems, and not an effort by each nation to get the better of other nations, to do harm to them when it is possible. I believe in morality, in justice, in humanitarianism.
