|MadSci Network: Physics|
This concept was entirely new to me as well, and the information
I could get out of the Santa Fe Institute's pages wasn't too
helpful either. I think what you refer to as ``The Physics of
Information'' is what they call
Mechanics''. They are trying to refine the very useful but
also rather crude concepts of statistical mechanics (especially
entropy, which measures, roughly speaking, the degree of ``randomness''
in a system). Entropy is an extensive potential, i.e. it is some
value that is valid for the whole system, regardless of its
``fine structure''. So if you want to get a refined picture of
the information contained and processed in some system, you have
to introduce new variables that describe the system in more
A collection of recent papers on these topics can be found here.
I hope I could be of some help to you.
