Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.

The controls of life are structured as forms and nuclear arrangements, in a relation with the motions of the universe.

Do not put forward anything that you cannot prove by experimentation.

... by chance you will say, but chance only favors the mind which is prepared.

In that memorable year, 1822: Oersted, a Danish physicist, held in his hands a piece of copper wire, joined by its extremities to the two poles of a Volta pile. On his table was a magnetized needle on its pivot, and he suddenly saw (by chance you will say, but chance only favours the mind which is prepared) the needle move and take up a position quite different from the one assigned to it by terrestrial magnetism. A wire carrying an electric current deviates a magnetized needle from its position. That, gentlemen, was the birth of the modern telegraph.

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

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.
