你说的“来自比特”是从哪来的?

Where the "it from bit" come from?

Luigi Foschini

摘要:

在1989年的文章中,约翰·阿奇博尔德·惠勒试图回答存在这个永恒的问题。他通过寻找信息、物理和量子之间的联系来做到这一点。从他的论文中出现的主要概念是,“每一个物理量,每一个它,都从比特,二元的是或否指示中获得其最终意义”。这一概念被概括为一句流行语“it from bit”。在惠勒的文章中,我们可以多次读到尼尔斯·玻尔哲学的回声。这位丹麦物理学家指出了量子和相对论物理学如何迫使我们放弃常识的视觉参考的锚-对语言施加了更大的关注。玻尔并不否认物理实在,但承认无论一个人想做什么,总是需要一种语言。用卡洛·西尼的话说,语言是人类手中用来分析经验的第一个工具箱。它不是一个被翻译成文字的思想,因为思考是用符号来运作的,从列奥纳多·达·芬奇到路德维希·维特根斯坦的各种哲学家都提醒过我们。[...]

英文摘要:

In his 1989 essay, John Archibald Wheeler has tried to answer the eternal question of existence. He did it by searching for links between information, physics, and quanta. The main concept emerging from his essay is that "every physical quantity, every it, derives its ultimate significance from bits, binary yes-or-no indications". This concept has been summarized in the catchphrase "it from bit". In the Wheeler's essay, it is possible to read several times the echoes of the philosophy of Niels Bohr. The Danish physicist has pointed out how the quantum and relativistic physics - forcing us to abandon the anchor of the visual reference of common sense - have imposed a greater attention to the language. Bohr did not deny the physical reality, but recognizes that there is always need of a language no matter what a person wants to do. To put it as Carlo Sini, language is the first toolbox that man has at hands to analyze the experience. It is not a thought translated into words, because to think is to operate with signs as reminded us by various philosophers from Leonardo da Vinci to Ludwig Wittgenstein. [...]
