Dear Christophe and Giuseppe, Thanks for the recent comments, really exciting . There is a direct connection between quantum & unpicturability (but do not have here the proper reference; it is one of the simplifications which allows approaching chemical bonds by making them independent on the atomic nuclei fluctuations). Next week I will answer better (preparing a trip now). About the question below, I quite agree with you, but people who fill in application forms have to be left to handle by themselves that excruciating job, without interferences. Even more when other societies were involved, not only FIS...

The case is in my view, that unpicturability refers to complexity "depth" and impredicativity to its "extension". Both are related, and maybe not quite well formulated. Regarding ecological-geodynamic networking matters (so crucial in microbial communities) and in the asymmetry between analysis and synthesis concerning biological nature as open systems (a fascinating theme also within Rosen's scope) something similar to impredicativity could be argued. Let us try ourselves to unify matters, by means of future exchanges, or even let us plan a devoted discussion-session... Why computational processes should be necessarely predicative? Girard's Type Theory (System F) is impredicative yet "fully computational" (it computes exactly the recursive functions provably total in second order Arithmetic). A detailed critique of Rosen's analysis is in: Matteo Mossio, Giuseppe Longo, John Stewart. Computability of closure to efficient causation. To appear, J. of Theoretical Biology, 2009. (ftp://ftp.di.ens.fr/pub/users/longo/CIM/comp-closure.pdf). The bibliog. references of both messages were really of interest (I will go for them next days...) best regards Pedro _______________________________________________ fis mailing list fis@listas.unizar.es https://webmail.unizar.es/cgi-bin/mailman/listinfo/fis
