Life is not easy for any for us.

I was taught the method for advancement is not quick or simple.

We must not forget that when radium was discovered no one knew that it would prove useful in hospitals.

I have frequently been questioned, especially by women, of how I could reconcile family life with a scientific career. Well, it has not been easy.

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

It is my earnest desire that some of you should carry on this scientific work and keep for your ambition the determination to make a permanent contribution to science.

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.
