David:
You speak of partition functions as possibly providing a deeper
understanding of the evolutionary process.
A partition function expresses the probability of various states
under certain canonical, or idealized, situations.
The entire mathematical process is enslaved to a kind of idealized
model of the "real" world of "particles," usually a "large"
number of them.
Information, as it has always been spoken of in ID, is not probabilistic.
It is about meaning, not the mere encoding of meaning (e.g., Shannon
information).
So how does a partition function relate to this kind of information?
The meaning in a cell is encoded in the alphabet of amino acids.
The partition function governs, not the meaning or code, but the
media in which the meaning is encoded.
Meaning appears to not be physical and therefore not governed by partition
functions. Somehow the meaning could be hidden in various initial conditions,
presenting "new" canonical situations and possibilities. The laws of statistics
and of physical laws are never sufficient to explain what is.
Can you say more of what you are thinking here with regard to partition functions?
It seems that the very notion of partition functions, or at least our ability to
be able to construct them, speak of a host of independent particles.
Whereas, information speaks not of independence but of a coherence that binds the
independence into a whole. In some sense, when we speak of statistical systems as
"seeking" minimums of free energy and the like this may be closer to information,
if we could get a handle on what "seeking" means.
Finally, you say,
"A cell isn't just biology. Its really chemical
engineering. And that mathematics is what governs populations of
molecules everywhere - organic or inorganic. Do you disagree?"
Wow! What a statement. I suggest you read this carefully.
A cell isn't only about biology, but it is *really* about chemical
engineering!? Isn't what you really mean is that a cell isn't
about biology at all, but about chemistry? Biology is reducible to
chemistry? And *mathematics* is what governs the chemistry.
Is this a form of Platonism, where the forms govern the instances?
I'm joking in part. I'm pretty sure you didn't intend to say just
this. I was just struck with what it literally seems to say.
