[Fis] A provocative issue

[tozziarturo at libero.it]

Dear FISers, 

I know that some of you are going to kill me, but there’s something
that I must confess.  

I notice, from the nice issued raised by Francesco Rizzo, Joseph
Brenner, John Collier, that the main concerns are always energetic/informational
arguments and accounts. 

Indeed, the current tenets state that all is information, information being a
real quantity that can be measured through informational entropies.

But… I ask to myself, is such a tenet true?

When I cook the pasta, I realize that, by my point of view, the cooked
pasta encompasses more information than the not-cooked one, because it acquires
the role of something that I can eat in order to increase my possibility to
preserve myself in the hostile environment that wants to destroy me.  However, by the point of view of the bug who
eats the non-cooked pasta, my cooked pasta displays less information for
sure.  Therefore, information is a very
subjective measure that, apart from its relationship with the observer, does
not mean very much…  Who can state that
an event or a fact displays more information than another one?

And, please, do not counteract that information is a quantifiable,
objective reality, because it can be measured through informational entropy…
Informational entropy, in its original Shannon’s formulation, stands for an ergodic
process (page 8 of the original 1948 Shannon’s seminal paper), i.e.: every sequence
produced by the processes is the same in statistical properties, or, in other
words, a traveling particle always crosses all the points of its phase space.  However, in physics and biology, the facts and
events are never ergodic.  Statistical
homogeneity is just a fiction, if we evaluate the world around us and our brain/mind.  

Therefore, the role of information could not be as fundamental as
currently believed.   

 

P.S.: topology analyzes information by another point of view, but it’s an issue for
the next time, I think…
