The problem is that replacement of Quantum Mechanics by Quantum Field Theory is still very demanding.

If it had been anything else, we would have said, 'People don't want us to do it. Forget it. Let's just leave it alone.' But this is not in that category. This is interesting science. New science. With a hint of a possibility of a very useful technology. Therefore, if you've got any integrity, you don't give up. You only give up if you find you are wrong. But as long as you believe that you are right, you have to continue. And you have to take the consequences.

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

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.

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

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.
