Marie Curie

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained.

Each of us must work for his own improvement, and at the same time share a general responsibility for all humanity.

First principle: never to let one's self be beaten down by persons or by events.

The various reasons which we have enumerated lead us to believe that the new radio-active substance contains a new element which we propose to give the name of radium.

It was like a new world opened to me, the world of science, which I was at last permitted to know in all liberty.

Nothing in this world is to be feared... only understood.
