You bring me the deepest joy that can be felt by a man whose invincible belief is that Science and Peace will triumph over Ignorance and War, that nations will unite, not to destroy, but to build, and that the future will belong to those who will have done most for suffering humanity.

Luck favors the mind that is prepared.

Fortune favors the well-prepared.

In the realm of scientific observation, luck is granted only to those who are prepared.

If you suppress laboratories, physical science will be stricken with barrenness and death.

Science knows no country because it is the light that iluminates the world

Blessed is he who carries within himself a God, an ideal, and who obeys it: ideal of art, ideal of science, ideal of the gospel virtues, therein lie the springs of great thoughts and great actions; they all reflect light from the Infinite.
