Now I know what the atom looks like.

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

Don't let me catch anyone talking about the Universe in my department.

I must confess it was very unexpected and I am very startled at my metamorphosis into a chemist.

The year 1896 ... marked the beginning of what has been aptly termed the heroic age of Physical Science. Never before in the history of physics has there been witnessed such a period of intense activity when discoveries of fundamental importance have followed one another with such bewildering rapidity.

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