We are rather like children, who must take a watch to pieces to see how it works.

If, as I have reason to believe, I have disintegrated the nucleus of the atom, this is of greater significance than the war.

When we have found how the nucleus of atoms is built up we shall have found the greatest secret of all — except life. We shall have found the basis of everything — of the earth we walk on, of the air we breathe, of the sunshine, of our physical body itself, of everything in the world, however great or however small — except life.
