I agree, Nigel. It is one of many areas of academia I have only had the slightest of links to but I remember reading a paper round about 1976 about the comparative efficiencies of languages when trying to express concepts. It was a fascinating idea and I regret I know so little about it. I hope it hasn't fallen entirely out of favour - I can imagine all sorts of political judgements being made by those on the outside of the research.
