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
