You know, I am sorry for the poor fellows that haven't got labs to work in.

All science is either physics or stamp collecting.

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.

I've just finished reading some of my early papers, and you know, when I'd finished I said to myself, 'Rutherford, my boy, you used to be a damned clever fellow.' (1911)

An alleged scientific discovery has no merit unless it can be explained to a barmaid.

From the results so far obtained it is difficult to avoid the conclusion that the long-range atoms arising from collision of alpha particles with nitrogen are not nitrogen atoms but probably atoms of hydrogen, or atoms of mass 2. If this be the case, we must conclude that the nitrogen atom is disintegrated under the intense forces developed in a close collision with a swift alpha particle, and that the hydrogen atom which is liberated formed a constituent part of the nitrogen nucleus.

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