Re: Information
Two people can taste food from the same bowl and one like it while the other won't. However now each know more about the flavour than if they had just looked at it.

Biological Information
Biological Information What is It?
Werner Gitt, Robert Compton, and Jorge Fernandez
quote:
But what do we mean by the term biological information? We suggest that, at present, it cannot be unambiguously defined.
quote:
This leads us to ask the more general question: What precisely is information? Anyone who has studied this field is aware of three working definitions of
information:
Classical Information Theory: Shannon (statistical) information [3]; dealing solely with the technical/engineering aspects of communication. This involves analyses including obtaining statistics on the material symbols for data transmission, storage and processing.
Algorithmic Information Theory: Solomonoff/Kolmogorov/Chaitin [4—6]; dealing with the ‘complexity’ (as this term is defined in the theory) of material symbols in data structures and of objects in general.
Complex Specified Information (CSI) Theory: Dembski [7]; roughly the same as Classical Information Theory but adding the important concept of a ‘specification’.
quote:
With the combination of abstract code and syntax we are able to generate more complex language structures such as words and sentences. However, at this (formal language) stage meaning plays no role. It was at this level only that Shannon developed his Theory of Communication [3] into the highly useful statistical analyses of the material symbols, solely for the technical purposes of data transmission, storage and processing.
