[Fis] Is quantum information the basis of spacetime?

[Loet Leydesdorff]

Dear Alex and colleagues, 

 

Thank you for the reference; but my argument was about “meaning”. “Meaning” can only be considered as constructed in language. Other uses of the word are metaphorical. For example, the citation to Maturana.

 

Information, in my opinion, can be defined content-free (a la Shannon, etc.) and then be provided with meaning in (scholarly) discourses. I consider physics as one among other scholarly discourses. Specific about physics is perhaps the universalistic character of the knowledge claims. For example: “Frieden's points apply to quantum physics 

as well as classical physics.“ So what? This seems to me a debate within physics without much relevance for non-physicists (e.g., economists or linguists).

 

Best,

Loet

Dear Loet and Fis Colleagues, 

 

Are you aware of Roy Frieden's 

'Physics from Fisher Information'. 

His book was published in the 1990s.

I consider it a very powerful statement. 

 

Ultimately everything we can detect at 

both macroscopic and microscopic levels 

depends on information production from 

a quantum level that forms Fisher Information. 

 

Frieden's points apply to quantum physics 

as well as classical physics. 

 

Best wishes, 

 

Alex Hankey

Dear Marcus, 

 

When considering things in terms of "functional significance" one must confront the need to address "meaning" in terms of both the living and the physical . . . and their necessarily entangled nature.

 

“Meaning” is first a linguistic construct; its construction requires interhuman communication. However, its use in terms of the living and/or the physical is metaphorical. Instead of a discourse, one can this consider (with Maturana) as a “second-order consensual domain” that functions AS a semantic domain without being one; Maturana (1978, p. 50): 

 

“In still other words, if an organism is observed in its operation within a second-order consensual domain, it appears to the observer as if its nervous system interacted with internal representations of the circumstances of its interactions, and as if the changes of state of the organism were determined by the semantic value of these representations. Yet all that takes place in the operation of the nervous system is the structure-determined dynamics of changing relations of relative neuronal activity proper to a closed neuronal network.”

 

Failing to "make that connection" simply leaves one with an explanatory gap. And then, once connected, a further link to "space-time" is also easily located . . .

 

Yes, indeed: limiting the discussion to the metaphors instead of going to the phore (that is, language and codification in language) leaves one with an explanatory gap. Quantum physics, for example, is a highly specialized language in which “mass” and “information” are provided with meanings different from classical physics.

 

Best, 

Loet
