[Fis] planckian information

[Pedro C. Marijuan]

Dear FISers,

quite many things have been said these days about our "family ghosts". 
Everyone has a different opinion on the under-information matter, and 
maybe that's healthy. Personally I have not changed very much the vision 
with which FIS was started many years ago. See in the descriptive text 
(http://fis.sciforum.net/about-fis/): "...At FIS, rather than the 
discussion of a single particularized concept, information becomes the 
intellectual adventure of developing a ‘vertical’ or ‘transdisciplinary’ 
science connecting the different threads and scales of informational 
processes, which demands both a /unifying/ and a /multi-perspective/ 
approach..."

With time my impression, already expressed in this list, is that there 
is a fundamental hiatus in our conceptions around biological information 
so that a meaningful connection with the several infos of the physical 
realm, and the miscellany of humanities can not be worked out. In a 
couple of recent discussions I was close to see with more clarity the 
problem, but again I feel blurred. It does not mean at all that I have 
an abandonment attitude. Conversely I think we are getting closer and 
closer. The fundamental fact of our generation is the stupendous new 
panorama that computers and the new technologies have opened on life, 
from the bioinformatics to the neurodynamics and the "topodynamics". To 
say something more concrete the big problem I see is how to enter the 
LIFE CYCLE as the generalized source and sink of the information flows.

And then the Planckian Information theme presented by our new colleague 
Sung looks quite intriguing. Why most of these information flows and 
energy flows exchanges are caught under that covering law? Anecdotally 
we (my research minigroup) are working in the sociotype, understood as 
the social communication structures surrounding the person. What is the 
average number of friends and acquaintances that we can maintain 
meaninfully? Probably you have heard about Dunbar's number (in between 
150-200), but what sort of statistical distribution would you obtain? 
Very easy, seemingly they follow a Planckian distribution. We have 
limited mental resources and have to keep an "economy" on our memory 
investment on other people...

Anyhow, the present discussion session may be important to make an 
indent on this curious commonality between the physical and the biotic 
arrangement of exchanges.

All the best--Pedro
