Cari Tutti, la neg-entropia (energia libera o INFORMAZIONE in condizione di dis-equilibrio improbabile) di "Che cos'è la vita? La cellula vivente dal punto di vista fisico" di Erving Schrodinger e la "evaporazione" di INFORMAZIONE di Stephan Hawking che compensa l'asimmetria tra entropia interna (minore) e l'entropia esterna (maggiore) dei buchi neri dove le mettiamo? Scusate la domanda. Francesco Rizzo
