<p>Dear FISers!</p>
<p>It is quite a long time without list activity... As you all know,
the IS4SI 2021 event just took place during last week . Many of
FIS parties participated, though it was complex to explore all
subconference tracks and follow them under the ZOOM scheme. It is
a new "virtual" regime that the pandemics has precipitated--and it
will stay... In any case, for those who missed the sessions, there
will be complete recordings available in due time.</p>
<p>Anecdotally, one of the discussion themes, biological &
computer codes, was raised by me during the final, closing
session. I had never thought about codes in that way. Joseph made
a quick response and sent later a message which I paste below. I
think continuing as an open discussion could be interesting for
the list.<br>
</p>
<p> Well, I realized that if we compare biological & computer
systems with inanimate systems, codes are one of the most
significant differences. Apart of the genetic code, there are many
biological others: metabolic codes, degradation codes, adhesion
codes, histone codes, sugar codes, cytoskeleton codes,
dvelopmental codes, neuronal codes, etc., etc. It is quite
interesting that prokaryotes did develop very few codes and so,
presumably, could not develop their constructive complexity.
Something similar would have occurred in the development of
computer architecture layers, based on increasing codes
hierarchically arranged in general. <br>
</p>
<p>I am not aware of any physical system which had created any kind
of code (except, hypothetically, in the origins of life). Well,
symmetry groups in crystallographic systems could be close, but
its constructive complexity is low, quite "flat", directly
dictated by the components... <br>
</p>
<p>Are codes really significant for the information realm? Do they
represent the obligatory way of channeling the inner
self-construction (dynamic) information flows?</p>
<p>Could there be a deeper discussion on codes? </p>
<p>All the best,</p>
<p>--Pedro</p>

Pedro and All,</font>
<div><font size="3"><br>
</font></div>
<div><font size="3">Just as the Conference was closing, Pedro
brought out the extremely important subject of codes, and the
result of my rushed interaction with him can be summarized as
follows: codes are epistemological; dynamics are ontological. </font></div>
<div><font size="3"><br>
</font></div>
<div><font size="3">This means that codes and dynamics co-exist
but are of a different nature. Codes describe the catalysts of
change in living systems, but they do not change themselves
without an input of energy/informatin. The same is true of
codes in non-living systems, say, inorganic catalysts that
degrade over time. Computer codes are purely epistemological,
as many of you have said in other terms.</font></div>
<div><font size="3"><br>
</font></div>
<div><font size="3">Codes and dynamics can</font><span
style="font-size: medium;"> be separated physically but not
functionally. They instantiate non-separability as a
fundamental principle.</span></div>
<div><font size="3"><br>
</font></div>
<div><font size="3">Thanks and to be continued, I hope.</font></div>
<div><font size="3"><br>
</font></div>
<div><font size="3">Best wishes,</font></div>
