I think this could make for a very interesting discussion some other time and in a different thread.
Mark, that creative vs technical argument is the same one that people who find the Zone System too technical use against the Zone System, and I don't think you'd agree with them. It's simply a matter of degrees. Yes, ultimately it's about creativity and personal expression. I don't think anyone path to art is intrinsically better than another, however, if the intention is to communicate technical information to others, certain methods don't measure up as well as the more scientific ones. They are all just tools.
PE's boss's words "we sell pictures not curves", shows great wisdom.
I think you might be a bit surprised. I really have no issue with not knowing certain things.
In the field I'm much more interested in concepts I can visualize rather than math I have to do.
