To turn this on it's ear, the answer is also that biology has not sought to
*ask* quantitative questions in many cases, and the complexity of biological
processes and difficulty in obtaining good quantitative measurements have
made applications of mathematics difficult at best. This occurs because the
trainning required of a 'true' biologist is such that very few of them also
manage to learn much math--this is not a disparagement just a result of the
complexity of biology. A mathematician, on the other hand, by focusing on
and learning narrow areas of biology, can bring insight. *But* I think that
many experimental biologists think that the processes are so complex as to
be impossible to model, and "Who is this upity modeler who thinks he/she can
learn enough about biology to describe it with math in a few months, when I
have been studying this all my life and I know that even the greatest experts
don't understand the biology completely." (This is essentially what I was
told when I proposed the development of a model of the menstrual cycle.)
The best response is: we learn the most from models when they fail, because
that disproves hypotheses.
I've been presenting the 1st half of my menstrual model, and some eminent
endocrinologists have been getting very excited about it. (Paper about to
be submitted.) So don't be all doom-and-gloom, Bob.
