I think you know that I classify science as British science, American science, and everybody else.

It is not necessarily true that expensive experiments are not worthwhile doing but there are plenty of rather cheap experiments which are certainly worth doing.

I don't suppose I'll ever retire completely.

American science is much more organized, much more hierarchical than British science has been.

One of my theme songs is that if you can't do it in a test tube, don't do it.

It has been suggested at various times that I should start an operation in the United Kingdom but - bearing in mind my age and medical history - I think this would be not a very sensible way to go forward.

It doesn't matter whether you can or cannot achieve high temperature superconductivity or fuel cells, they will always be on the list because if you could achieve them they would be extremely valuable.
