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

My husband and I were so closely united by our affection and our common work that we passed nearly all of our time together.

When one studies strongly radioactive substances special precautions must be taken if one wishes to be able to take delicate measurements. The various objects used in a chemical laboratory and those used in a chemical laboratory, and those which serve for experiments in physics, become radioactive in a short time and act upon photographic plates through black paper. Dust, the air of the room, and one's clothes all become radioactive.

Radium is not to enrich any one. It is an element; it is for all people.

Now is the time to understand more, so we fear less.

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.

We must have perseverance and above all confidence in ourselves.
