<p class="MsoNormal" style="margin:0cm 0cm 8pt;font-size:12pt;font-family:"Times New Roman",serif">The intermission was indeed unusually long this time, but
Vivace of the movement that is beginning now satisfies for the waiting. <span></span></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt;font-size:12pt;font-family:"Times New Roman",serif">Pedro introduces the theme:<span></span></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt 36pt;font-size:12pt;font-family:"Times New Roman",serif"><span>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, developmental codes, neuronal codes, etc.,
etc.<span></span></span></p>

<p class="MsoNormal" style="margin:0cm 0cm 8pt 36pt;font-size:12pt;font-family:"Times New Roman",serif"><span>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.<span></span></span></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt 36pt;font-size:12pt;font-family:"Times New Roman",serif"><i><span>Rules have hierarchies<span></span></span></i></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt;font-size:12pt;font-family:"Times New Roman",serif">Countermelody to the theme:<span></span></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt 36pt;font-size:12pt;font-family:"Times New Roman",serif"><span>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... <span></span></span></p>

<p class="MsoNormal" style="margin:0cm 0cm 0cm 36pt;font-size:12pt;font-family:"Times New Roman",serif"><span style="font-size:13.5pt">There is a
need to reorder (from day/night optimal to tide in/out optimal), so that
element which is the <i>i-th </i>in the order Previous will occupy the place of
that which is <i>r-th</i> in the order Previous which in turn will occupy the
place of that which is <i>q-th</i> in the order Previous which in turn will
occupy … etc etc<span></span></span></p>
<p class="MsoNormal" style="margin:0cm 0cm 0cm 36pt;font-size:12pt;font-family:"Times New Roman",serif"><span style="font-size:13.5pt">This is an
elementar, basic, fundamental fact. The fact holds, that if any reorder from
Previous into Present takes place, well-defined and well-named elements will
team up with other well-defined and well-named elements to build a sequence of
replacements. The property can be any, magnetism, chemical valence or good
looks and fine smell. The corresponding mental pictures can be strings,
filaments, force fields, coherence and predictability. The structure, the web
of possibilities is immanent in the Acervus, our common heritage of
indisputable facts, on which we base our axioms.</span><span><span></span></span></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt 36pt;font-size:12pt;font-family:"Times New Roman",serif"><i>Rules are the part and parcel

<p class="MsoNormal" style="margin:0cm 0cm 8pt;font-size:12pt;font-family:"Times New Roman",serif">Karl comes in with supporting rhythm, integrating both
themes:<span></span></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt 36pt;font-size:12pt;font-family:"Times New Roman",serif">The cycles have a two-fold
existence: they are ever-lasting as implications of the sentence “<i>A Change
from Previous to Present takes place, Aspect X, stage i”. </i>As such, this
rule has almost as long a shelf life as <i>a = a,</i> because if periodic changes
do take place, this specific given choreography of elements will have to take
place in a rational world for any given periodic change. If a fire drill is
executed, it is irrelevant whether the location is a factory, a bank or an
airport. The goal of the previous is to reach the present in the relevant
aspect, and this logistical manoeuvre has its own rules of which element
replaces which other element etc until the goal is achieved (and such an
optimised state is reached as is appropriate for the actual day/tide
combination). <span></span></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt 36pt;font-size:12pt;font-family:"Times New Roman",serif">The other kind of existence for a
rule is a heroic one. The rule in such cases presents itself and asserts that
it exists. The rule is by no means eternal, the action is in fact around the
plot, how long a rule can hold itself against the aspirations of other rules. <span></span></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt 36pt;font-size:12pt;font-family:"Times New Roman",serif"><i>Which rules are to be observed
comes from which changes take place. One can influence which changes take place
by selectively observing rules.<span></span></i></p>
<p class="MsoNormal" style="margin:0cm 0cm 8pt;font-size:12pt;font-family:"Times New Roman",serif">Karl gives back to the melodists. The rhythmic interplay has
shown that Pedro’s overture with a lead melody and Joseph’s doing a contrast and integration on
the theme are both converging on the same subject: is there a way to build a
road from the name-giving areas of the brain to the non-quadrivial areas of the
brain?<span></span></p>

<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>

<div lang="x-unicode"><font size="3">Dear
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>

</font></div>
<div><font size="3">Thanks and to be continued, I hope.</font></div>
