[Fis] SYMMETRY & _ On BioLogic

[Pedro C. Marijuan]

Dear FIS Colleagues,

Let me start by announcing the *special session on *_*INFORMATION & 
SYMMETRY*_, in the Symmetry gathering this Summer in Vienna (18-22 July) 
http://festival.symmetry.hu/ The deadline for abstract reception in this 
session has been enlarged until beginnings of next month. Tentatively, 
it will be chaired by our colleagues Jerry Chandler and Abir 
Igamberdiev. A special issue has been planned in cooperation with the 
journal "Information" too. We will celebrate the near 20th anniversary 
of the first joint session with FIS on information and symmetry 
(Washington 1995) and the subsequent special issues (Symmetry & Culture, 
1996 and 97). It will be a good occasion to meet again and pass over the 
views developed in this period. Old FISers and members of this list are 
invited to attend.

And then about the ongoing discussion--responding to the exciting 
exchanges by Louis and Plamen. This type of abstract discussion is 
rarely fertile for biological fundamentals, where structure and function 
become so intertwined that the concrete mechanisms obliterate the quest 
for too far-reaching generalizations, but it may be interesting for 
approaching problems such as "distinctions". Some time ago I tried an 
approach not so different from Spencer Brown's. It was based on 
"multidimensional partitions", a development of Karl Javorszky (of this 
list) for set theory out from classical Euler's partitions (the 
different ways to decompose additively a natural number). It was very 
interesting finding a natural limit for the total distinctional between 
members of given set, finding a curious info dynamics of distinctional 
gains and losses after addition of just one sign or a few signs in the 
set, a sort of power law in the total decomposition, etc. (most of this 
was coming from previous works by Karl--we somehow improved the 
algorithmic, with a few colleagues here in Zaragoza). Then we tried to 
apply it to prokaryotic complex receptors (2CS, 3CS) and to the 
"language of cells"... but we reached our math limits very soon (anyhow, 
some elementary drafts and publc. were left). I keep thinking that it 
was a serious approach to cellular "distinctions" that could be 
escalated upwards. Later on, in a couple of papers in BioSystems (2010, 
99, 94-103; and  2013, 114, 8-24) we roughly described prokaryotic and 
eukaryotic signaling machinery in relation with the intelligent 
advancement of the life cycle of each cell.

About viruses in evolution, we could listen in Vienna (IS4IS & FIS 2015 
Conference) to one of the most advanced thinkers, Guenther Witzany. What 
Plamen suggests about a virus theory from the viewpoint of viruses is 
not science fiction. It is astonishing what a few crucial proteins of 
HIV "know" about hundred molecular components of our lymphocytes. It is 
as if they had conspired with structurally enslaved pieces of former 
viruses temporarily joining them to create havoc in the machinery of the 
cellular host. If just 30% of what Guenther says is right, we have to 
revise the Symbiotic Theory, the Central Dogma, the RNA (inner) cloud, 
gene expression, biosemiosis, etc.

Echoing the final debates of the previous session, description should go 
first. And in bio-informational matters there is still plenty to describe.

Best regards--Pedro
