The more physics you have the less engineering you need.

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.

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

The more physics you have the less engineering you need.

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

Radioactivity is shown to be accompanied by chemical changes in which new types of matter are being continually produced. .... The conclusion is drawn that these chemical changes must be sub-atomic in character.

All science is either physics or stamp collecting.
