Re: Mathematics and Analogy

Judith, something must be wrong: this is another time
within a very short period that I praise your post.
(ha ha). You had the right conclusions to RR's right
quote - well evaluated and commented.
Now let me add my tuppence and paraphrasing to the
topic and my question whether RR went into such
considerations in his writings?
*
True: math is a complex on its own, using its own
language and mindset. Pure, theoretical math, that is.
I find it a bit simpler than the 'regular'
complexity-talk, as seen in your RR-quote, for numbers
vs burning-floating-etc. aspects of the sticks. One
plane logic, as I like to say. Mathematicians get
along with that OK. Alas, many other can learn it who
work in reductionist topical sciences and APPLY their
math knowledge to their model-views. This constitutes
"Applied Mathematics" in physix, biol, econ, gen, geo,
etc. etc. models. Limited, cut values within the
topical boundaries are included in equational math,
applying all the complexity-deducted 'rules' math
could come up with. The equations between the cut
model-values do not fit in a simple way which requires
constants, modifiers, a convoluted treatment to make
it stick. Inadvertently also paradoxes occur. -"High
sci".-
Mathematicians who prostitute themselves into the
model-based math application, make good money in
successful technology development. (Analogy: a gifted
musician who 'rockify' a Bach or Beethoven tune to
make a good buck from the teen-crowd).
Make no mistake: applied math is successful and
contributes very much to humanity's advancement. I am
talking theoretical aspects.
One cannot draw a trajectory of a million-body system,
or build a machine or software on unlimited
(~infinite?) variable functions.
I would paraphrase your sentence:
">...Robert Rosen argued that the system had been
> changed from one that was complex to one that is
simple....<
into:
> Application of the 'natural' math system to the
reductionist model-sciences made it into a 'mental
machine'. <
This is my prejudice and I do not expect a general
approval. Tim?
