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.

I was taught that the way of progress was neither swift nor easy.

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

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.

A scientist in his laboratory is not a mere technician: he is also a child confronting natural phenomena that impress him as though they were fairy tales.

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.

I never see what has been done; I only see what remains to be done.
