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

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.

The sensitive plate, the gas which is ionised, the fluorescent screen, are in reality receivers, into another kind of energy, chemical energy, ionic energy... luminous energy.

You cannot hope to build a better world without improving the individuals. To that end each of us must work for our own improvement, and at the same time share a genaral responsibility for all humanity, our particular duty being to aid those to whom we think can be most useful.

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.

Certein bodies... become luminous when heated. Their luminosity disappears after some time, but the capacity of becoming luminous afresh through heat is restored to them by the action of a spark, and also by the action of radium.

I have no dress except the one I wear every day. If you are going to be kind enough to give me one, please let it be practical and dark so that I can put it on afterwards to go to the laboratory.
