Yes, many posts back silly pete burst on to this thread spouting some claptrap about 'science' (of which he obviously has no understanding whatsoever). His interjections are like the proverbial 'red-rag-to-a-bull' to those of us with a scientific background. I suppose that we should really ignore the ignorant fool but then, perhaps, we have a duty to counter unreason whenever the opportunity presents itself (?) We should really stick to the thread topic though - go away and boil your silly head, pete!
