No, there isn't, and that's the point you keep missing.

Remember what I wrote about the stumbling blocks that keep people from
understanding an idea? I'll repeat them here: "The stumbling blocks are a
lack of education, a lack of source material to study, ignorance of the
existence of the concept, a lack of confidence, a lack of interest or
stubborn refusal. Once these are overcome, I believe anyone can learn
anything, intelligence notwithstanding." As I said, my experience (as a
teacher, lecturer, debator, tutor and scientist) has been that this is true.

I know; that's the entire problem. Perhaps the reason you believe this is
because you are not a good enough teacher to get the concept across to
people, or you bore them to the point that they loose interest, or you
shower them with technical jargon and equations you do not adequately
explain and thus confuse them to death.

I should add that to the list of stumbling blocks as well: some people who
really want to understand get bad teachers.

I am not what you would call a highly intelligent person. I got C's in
biochemistry, I barely understood evolutionary theory when it was first
taught to me, and I am not now a theorist (I'm good with my hands, not my
mind). But I have had no trouble understanding the most esoteric of
cutting-edge physics, because I had good teachers who were able to explain
everything so that I could understand it. (The same has been true of my
profession as well; with two exceptions, I've learned more about
biochemistry, protein chemistry and enzymology from my PIs than I did in
college.)

And as I wrote below, that has nothing to do with intelligence or reasoning

As a matter of fact yes; I have a MS in Biochemistry specializing in protein
chemistry and enzymology, with over 15 years experience in research. And
I've seen promising people quit or get washed out because they didn't get
the education, the training or the experience they needed to go where they
wanted to (which is why I try to help students who come through my labs as
much as I can) and I've seen promising people get crushed under the mountain
of paperwork and committee work and funding work they have to do to keep
going but which also keeps them out of the lab (which is why I try to help
my PIs as much as I can doing the lab management as well as most of their
lab work) and in my case I have not gotten as far as I would have liked
(yet) because of bad luck.

Yes they do; evolution is one such theory, but since biology is not physics,
biological theories will not be like physical theories.

No it's not; you use the term too strictly. I have yet to meet a physicist
(who wasn't a creationist or IDer that is) who used theory as strictly as
you do. In fact, the way I defined theory is how philosophers of science
generall define it.

One of the ways in which protein chemistry and enzymology is advancing is by
the incorporation of quantum mechanics to explain protein folding and enzyme
catalysis. If proteins are artifacts, then these artifacts would be
controled by quantum field mechanics. As such, any quantum field theory
developed to explain protein folding and/or enzyme catalysis would be
dealing directly with artifacts. Ditto if we ever develop nanotechnology or
protein-based processors. I have also read recently of quantum-based
transisters; these would also be artifacts governed by quantum field
theories.

You seem to believe that I think of theories as magical formulas, my friend;
simply write them down or say them into the air and miracles happen. Give
me a break. As I said before, theories explain how phenomena work; once we
understand that we can then use those theories to instruct us on how to
manipulate the phenomena to do work for us. As you say, a theory is just
ink on paper, or better yet a conceptualization, but using that
conceptualization we can develop the technology which allows us to
manipulate the forces and phenomena explained by that theory. Writing or
speaking Newton's law of gravitation naturally does not cause planets to
appear as if by magic. (By the way, Newton had no "theory" of gravitation;
he only described what gravity did, he didn't attempt to explain how it
worked. In fact when challenged with the critique that his law was
meaningless without such an explanation, he responded that he did not
hypothesize, by which he meant he did not speculate about what he could not
test.) However, knowing that law we can guide unmanned, unpowered planetary
probes around the solar system. And perhaps some day we will have the
technology -- based on Newton's law -- to create our own planets.

Regarding your question about life, I cannot "create" life simply by
writting out all the theories that govern life, but I can use those theories
to develop the technology I need to manipulate the physiochemical forces
into forming life in the lab.

We would know how life came into being certainly; beyond that I don't know
what you are referring to. By the way, we have done it; read the scientific
literature.

That's vitalism, which is rejected by modern biology as being untestable.
Instead, modern biology is based on molecular dynamics, which is inherently
materialistic. If you have evidence to the contrary, however, I would like
to see it.
