Loyal and efficient work in a great cause, even though it may not be immediately recognized, ultimately bears fruit.

A great disaster is a symbol to us to remember all the big things of life and forget the small things, of which we have thought too much.

It is science alone that can solve the problems of hunger and poverty, of insanitation and illiteracy, of superstition and deadening custom and tradition, of vast resources running to waste, or a rich country inhabited by starving people... Who indeed could afford to ignore science today? At every turn we have to seek its aid... The future belongs to science and those who make friends with science.

Peace is not a relationship of nations. It is a condition of mind brought about by a serenity of soul. Peace is not merely the absence of war. It is also a state of mind. Lasting peace can come only to peaceful people.

You don't change the course of history by turning the faces of portraits to the wall.

Time is not measured by the years that pass by, instead by the things you do, feel or accomplish.
