All science is either physics or stamp collecting.

Gentlemen, now you will see that now you see nothing. And why you see nothing you will see presently.

That which is not measurable is not science. That which is not physics is stamp collecting.

Now I know what the atom looks like.

Every good laboratory consists of first rate men working in great harmony to insure the progress of science; but down at the end of the hall is an unsociable, wrong-headed fellow working on unprofitable lines, and in his hands lies the hope of discovery.

The energy produced by the breaking down of the atom is a very poor kind of thing. Anyone who expects a source of power from the transformation of these atoms is talking moonshine.

It is essential for men of science to take an interest in the administration of their own affairs or else the professional civil servant will step in - and then the Lord help you.
