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

We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. The work was one of pure science. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it. It must be done for itself, for the beauty of science, and then there is always the chance that a scientific discovery may become like the radium a benefit for humanity.

There are sadistic scientists who hurry to hunt down errors instead of establishing the truth.

You cannot hope to build a better world without improving the individuals.

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.

We must have perseverance and above all confidence in ourselves.

I have the best husband one could dream of; I could never have imagined finding one like him. He is a true gift of heaven, and the more we live together the more we love each other.
