There was obviously some kind of thinking that the language was indispensible and science just wasn't very important, but I didn't pursue it very far. -- "Experiments are the only means of knowledge at our disposal.

The ironic problem is that people are also steered away from teaching in high school if it becomes a big political football between the government and the teachers, as has happened here in BC. Because of the politics of the situation hiring isn't dependent on factors such as retirement rates, new intakes of students, etc, it's dictated by how much money the government can chop out of the budget and not make everybody scream. This means new intakes of teachers will be hampered for years, and in my case I'm not willing to chance that uncertainty. So I've decided to go on to my Ph. D. :) Which I will have, eventually. *groan*... still a long way ahead. -- David Cross dcross1 AT shaw DOT ca

Well I know that part of the problem for me was that there were so many classes and such things you had to do in order to become certified to teach at a school. It was a real turnoff. I see your point in blaming the science departments, but I think it's rather strange that the education departments I've seen demand so little technical training in order to teach math or science.

Are you asking what holds the electron bound to the proton? Or are you asking why they keep moving and don't eventually stop? The answers to the two questions are different. PD

Sit the school board down and force them to do a page of long division of polynomials and then a page of derivatives. Hopefully there's at least one person who can do it and he or she will convince the others that they have made a grave error in the curriculum.
