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

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

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.

We must have perseverance and above all confidence in ourselves.

Sometimes my courage fails me and I think I ought to stop working, live in the country and devote myself to gardening. But I am held by a thousand bonds, and I don't know when I shall be able to arrange things otherwise. Nor do I know whether, even by writing scientific books, I could live without the laboratory.

It's always good to marry your best friend.
