[Fis] [Fwd: RE: It from Bit redux . . . MODERATION] From Xueshan

[Francesco Rizzo]

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.

>  Dear Pedro, Joseph, John, Krassimir, Rafael, and All,
>
> Here I tell you some interesting stories about “It from Bit” in China.
>
> Around the year of 2000, The Seminar of Interdisciplinary Information
> Science of Peking University came into contact for the first time with
> Wheeler’s “It from Bit”, in fact, earlier this theory, we had just
> discussed Stonier’s “Information Physics” and had consulted with the Dean
> of Physics School, his opinion was: The concept ENTROPY is enough to
> physics, it is unnecessary to blunder in the fashion of information for
> physicists. Of course, that was over fifteen years ago.
>
> We afterwards had been tracking this information problem in Science of
> China History; So far, we found there are at least four doctrines related
> to “It from Bit”.
>
> 1. It from Taiji. Zhou Wenwang (Ji Chang), see his book: “The Book of
> Changes” (Yijing or Zhouyi), B.C. 1050;
> 2. It from Dao. Laozi. see his book: “Tao Te Ching” (Daodejing), B.C. 500;
> 3. The world is composed of information. Xinxi Shen, see his book:
> “Informatilism”, 2005;
> 4. The world is informational. Jianghuo Wang, see his book: “Unified
> Information Theory”, 2012.
>
> To my knowledge, the last two authors had not contacted Wheeler’s “It from
> Bit”, that Ji Chang and Laozi had no contacted with it is very obvious.
>
> In all his lifetime, Wheeler once visited China only one time in 1981,
> when he stayed in China, he watched a Beijing Opera named “Feng Ming Qi
> Shan”. When a general hold a flag on which a large Chinese word appeared,
> he asked the accompany that what is the meaning of that word, they told him
> its meaning is NOTHING, he said excitedly: The answer what I am looking for
> desperately all my life about the physical reality, your ancestors had
> originally given thousands years ago. (see his book: “Wheeler’s Lectures on
> Physics and Austerity”, 1982).
>
> So far, on the argument of “It from Bit”, we can not prove it is correct,
> but can not prove it is wrong too.
>
> Best wishes,
