Facts are the air of scientists. Without them you can never fly.

Science is the search for 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 t he right solution, the just solution of international problems, not the effort by each nation to get the better of other nations, to do harm to them when it is possible.

The best way to have a good idea is to have lots of ideas.

Satisfaction of one's curiosity is one of the greatest sources of happiness in life.
