I think there is often a danger in believing that models are reality
rather than a convenient and current explanation. Francis Crick was
once quoted as saying that it was "all too easy to make some
simplifying assumptions, do some elaborate mathematics that appear
to give a rough fit with at least some of the experimental dataa,
and think that one has achieved something".
Models are certainly helpful and the best areparticularly so. But we
should not kid ourselves that they are a substitute for hard data.
