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 am among those who think that science has great beauty.

This means that we have here an entirely separate kind of chemistry for which the current tool we use is the electrometer, not the balance, and which we might well call the chemistry of the imponderable.

After all, science is essentially international, and it is only through lack of the historical sense that national qualities have been attributed to it.

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

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.

If it takes a hundred years, it will be a pity, but I will not cease to work for it as long as I live.
