Sorry, but it has already been done by people like Wheeler, Gell-Mann and
Hawking. You are not going to win against them.
GR: I don't recall Wheeler or Hawking relating Information theory to organic
systems.
Also, much broader usages have been developed over time in many other
disciplines than physics. Shannon invented communications theory, which is a
branch of information theory. Information was used more broadly before his work
(e.g. Schroedinger, Szillard) in organic chemistry, thermodynamics and biology.
GR: John show me these specific references, i have some of the original texts
on
Information theory there is no mention of Schroedinger or Szillard using
Information theory in thermodynamics and biology or organic chemistry.
Information thoery and its relation to physics was done by Johnson and Nyquest
to my knowledge.
GR: In my opinion it still only does, I cant get my head around how say
information theory actually applies to direct human communication or organic
sensing systems. All our sensing systems are energy transduction systems, once
inside the individual it 's moved via Na/K pumps aided by ADP to ATP
conversions
to the brain all electrical, chemical energy. So in the environment it's just a
sound (phonon) or light (photon) or chemical or heat energy where are the bits
(information theory part) or markers. They are just not there.

Information has to be interpreted. It does not come with meaning, attached,
though standard conventions, habits, biological predispositions and the like
can obscure this.
The full relation between information and energy still needs to be worked out,
I
believe.
GR: You can say that again.
However, information can be used to do work with no additional energy input
(see
some past posts on this topic), which suggests a very close connection.
GR: That's thermodynamically impossible. Any organic system requires to convert
and transduce energy so you may think it does no work but the relationship is
like Ostwald's Ripening there is always an energy cost.
