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 ( "...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
