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

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

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.

Scientists are really very conscious of the fact that they stand on the shoulders of an enormous tree of preceding workers and that their own contribution is not so enormous.

I think British science is becoming more like American science - and then there is everybody else, I'm afraid.

I have had this view of the optimization of the electrode design for a long time. Historically we went through various phases in the work and eventually worked on large sheets - very large sheets - of palladium.

Usually, if you have a new idea, you very rarely break through to anything like recognizable development or implementation of that idea the first time around - it takes two or three goes for the research community to return to the topic.
