Subject: RE: [Fis] non-living objects COULD NOT “exchange information”

I wrote this a few days ago, but it is still worth posting. I might add that 
biological entities making choices grades off into cases where there is only 
one choice. If determinism is true, then there are no real choices. If it is 
false, that doesn’t help either.

There are cases that I have given references to on this list in which 
information, but no energy leads to step climbing, indicate transformation of 
information into energy. Though the example was constructed by experimenters, I 
see nothing that could not result from a fortuitous set of physical 
circumstances. The movement could be used to trigger an informational even 
(turn a switch, for example, or select a quantum state), though turning 
information into information.

I suspect there are simpler examples, and leave the list to come up with the. 
All I wanted to do was to demonstrate principle.  We tend to give almost 
magical properties to life. Thai violates my understanding of General Systems 
Theory, which applies the same principles to all systems from top to bottom, 
rather than trying to find everything in the lowest levels, as in physicalism.

Dear  Lars-Göran,
I prefer to use asap my second FIS bullet, therefore it will be my last FIS 
mail for the next days.

First of all, in special relativity, an observer is NOT by definition a 
material object that can receive and store incoming energy from other objects.
In special relativity, an observer is a frame of reference from which a set of 
objects or events are being measured.  Speaking of an observer is not 
specifically hypothesizing an individual person who is experiencing events, but 
rather it is a particular mathematical context which objects and events are to 
be evaluated from. The effects of special relativity occur whether or not there 
is a "material object that can recieve and store incoming energy from other 
objects" within the inertial reference frame to witness them.

Furthermore, take a photon (traveling at speed light) that crosses a cosmic 
zone close to the sun.  The photon "detects" (and therefore can interact with) 
a huge sun surface (because of its high speed), while we humans on the Earth 
"detect" (and can interact with) a much smaller sun surface.
Therefore, the photon may exchange more information with the sun than the 
humans on the Earth: both the photon and the humans interact with the same sun, 
but they "detect" different surfaces, and therefore they may exchange with the 
sun a different information content.
If we also take into account that the photon detects an almost infinite, fixed 
time, this means once again that it can exchange much more information with the 
sun than we humans can.


In sum, once again, information does not seem to be a physical quantity, rather 
just a very subjective measure, depending on the speed and of the time of the 
"observer".

Re: [Fis] non-living objects COULD NOT “exchange information”

2017-03-24 Thread Karl Javorszky
1) Let me second to the point Alex raises:
machines, computers, do exchange information. It would be against cultural
conventions to say that the notification that the refrigerator sends to
your phone's app "to-do-list" of the content "milk only 0.5 liter
available" is not an information.

The signals my car's pressure sensor sends to my dashboard, saying "tire
pressure front right wheel is critically low" is a clear case of
information, whether I read it or not.

2) Let me add to the point Alex states, namely that the "form of
information that I presented to FiS a year ago offers the only
scientifically based,mathematical physics form of 'information' that I have
personally seen in the scientific literature", (Alex, will you please
restate in the present context, for the present discussion, your
formulation) the following:

I have given in my work "Natural orders - de ordinibus naturalibus" (ISBN
9783990571378) the following definition of the term "information":
8.3.3.3 Information is a description of what is not the case.
[Let *x = a**k*. This is a statement, no information contained. Let *x = a*
*k* and *k ** {1,2,...,k,...,n}*. This statement
contains the information *k ***
*{1,2,...,k-1,k+1,...,n}*.]

And let me add: a photon is not something that can exchange information, or 
energy or anything whatsoever. A photon is portion of electromagnetic 
radiation, it comes into exitence when a material object decreases its energy 
and is destroyed when another (or the same) material object absorbs that 
portion. A photon cannot increase its energy, or decrease it. And, of course, 
we cannot attribute information or information change to it.

Furthermore, as was proved by Gegerfeldt and Malament quite some time ago, a 
particle interpretation of quantum electro dynmaics is impossible. So thinking 
that a photon is confined to well defined portion of  spacetime contradicts QED.
