We haven't got the money, so we've got to think.

Splitting the atom is like trying to shoot a gnat in the Albert Hall at night and using ten million rounds of ammunition on the off chance of getting it. That should convince you that the atom will always be a sink of energy and never a reservoir of energy.

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

All of physics is either impossible or trivial. It is impossible until you understand it, and then it becomes trivial.

I am a great believer in the simplicity of things and as you probably know I am inclined to hang on to broad & simple ideas like grim death until evidence is too strong for my tenacity.

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.

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