Hi there Guy I'm at a loss still about information you mention below.
If one talks about waves, light, sound these are all energy (frequency) concepts. Chemistry and physics are really only about energy, entropy and transduction's and conversions of energy in one form or the other of matter. Any flows of available energy are more than likely entropy production or free energy. (Gibbs type free energy) The only codes, and notations are the ones we give it, it is of our own making, if information does have an existence then its more than likely related to non baryonic matter. After all we are making assumptions about a universe with only a less than 4% understanding of its contents. Regards Gavin Greetings All, I want to second Joseph’s claim that something may be transferred as information, even if Stan’s “stuff” itself is not transferred. Waves, for example, can often pass from one medium into another without a concomitant transfer of stuff, and the form of the wave may be changed when it enters the new medium. The energy of the wave, which can generally be measured by its physical manifestations (e.g., particle densities, free energy concentrations, local gradients and potentials...) may be sustained in a temporally and spatially coherent way as it flows. I personally like to think about information as contrast, such as with local gradients, and in this sense we might say that it it the information itself that flows into a recipient. Interpretation, then, involves the change in form that can occur in the new medium. Of course, information, like waves, are not always able to penetrate any new medium or system. It can be damped out in some transitions, and amplified through resonance in others. I think this perspective bridges some of the seemingly disparate views that have been voiced over the last week.

The standard meaning of information is also "restricted" in some senses. The dimension that Krassimir and his source are pointing to is not "just" poetic, but describes real interactions between sender and receiver.. However, I would criticize absolute statements such as "nothing is transferred". In my approach to logic (which I hope John includes in his "various" logics), it is not necessary to make an absolute distinction between the concept of information and its causal and material properties. They are dialectically linked. On the other hand, I think it is important to emphasize, as Krassimir does, that there are properties of information that cannot be measured. This point, and the others above, will not constitute an entire, monolithic Information Theory, nor its entire essence. But they should be taken into account as part of the "common" meanings of various theories which I, /pace/ John :-) find most interesting..

This usage is firmly entrenched in physics, used by such notables as Gell Mann, Wheeler and Hawking. So as far as usage of the word "information" is concerned, you were trumped long ago. I suggest that you, when using the word "information" make clear that you are using a specific restricted meaning rather than the general term. In fact I think that everyone on the list should practice similar hygiene. The word "information" has a range of meanings that are related much like Wittgenstein's family resemblances. It is perhaps a paradigmatic case of this. Anything in common is pretty basic, and not very interesting, to my mind, but worth working out in any case. There are connections of information theory to various logics, including the logic of distinctions and its extensionally equivalent propositional logic, predicate logic, and various other logics of a more restricted realm. These are all worth working out. However I think it is pointless, or nearly so, to try to find the one true meaning of 'information' (I use the philosopher's convention for single and double quotes in this post). I wish people would just let it go, and learn to be more flexible and open to different approaches that they don't find intuitively or experientially appealing. John At 01:22 PM 1/31/2011, Pedro C.

Please ask your dog or cat, or the birds around, what is the information? No answer. But they really âthinkâ as us.  Every live creature reacts to the external influences and this cause internal activity in the brain, in the cells of our body, etc.  Internal activity cause both new internal and external activity of our organism.  Our external activity cause reactions in the live creatures around, and so on ...  Not only. Our organism is variety of sub-systems, live sub-systems, and they act the same way, etc. .  At the end, what is the information?  A kind of reflection (result of the influence), which cause our internal activity.  In the same time, such kind of reflection may exists at the lower layers of our organism. This way, we may say, there is information at these layers. More, by analogy, we may say there is information in every living creature.  But only humans call it âinformationâ and try to measure it. Of course, in such case we will measure everything, but not the âinformationâ itself.  Because the internal activity closely depends of individuals and internal structure of the brain and configuration of neurons. The same we may say for the internal structure of the cells ...  Friendly regards Krassimir  ----------------------------------------------------------- _______________________________________________ fis mailing list fis@listas.unizar.es https://webmail.unizar.es/cgi-bin/mailman/listinfo/fis ________________________________ Professor John Collier, Acting HoS and Acting Deputy HoS colli...@ukzn.ac.za Philosophy and Ethics, University of KwaZulu-Natal, Durban 4041 South Africa T: +27 (31) 260 3248 / 260 2292 F: +27 (31) 260 3031 http://collier.ukzn.ac.za/ <http://collier.ukzn.ac.za/> -- ------------------------------------------------- Pedro C.
