termodinamica e complessità in un articolo del giornalista Pietro Greco, scritto tempo fa, ma sempre attuale.
Sistemi lontani dall'equilibrio
In un articolo dal titolo “Science and Complexity”, pubblicato nel 1948 sulla rivista American Scientist, il matematico Warren Weaver sosteneva che in natura esistono tre diverse classi di sistemi dinamici: a) i “sistemi semplici”, caratterizzati dalla presenza di poche variabili, tradizionale oggetto di studio della fisica e delle discipline medico-biologiche fino all’800; b) i “sistemi a complessità disorganizzata”, caratterizzati da un numero estremamente elevato di variabili, ciascuna tuttavia con un comportamento individuale casuale o sconosciuto. Questi sistemi, scriveva Weaver, possono essere trattati in termini di proprietà medie e di regolarità dell’insieme; c) i “sistemi a complessità organizzata”, caratterizzati da un numero considerevole di variabili connesse in un tutto organico. Sono questi i sistemi che incontriamo in biologia, in medicina, in psicologia, in economia e nelle scienze politiche.
