Interesting quote about all that (and information)
Frank Wilczek: "Information is another dimensionless quantity that plays a
large and increasing role in our description of the world. Many of the terms
that arise naturally in discussions of information have a distinctly physical
character. For example we commonly speak of density of information and flow of
information. Going deeper, we find far-reaching analogies between information
and (negative) entropy, as noted already in Shannon's original work. Nowadays
many discussions of the microphysical origin of entropy, and of foundations of
statistical mechanics in general, start from discussions of information and
ignorance. I think it is fair to say that there has been a unification fusing
the physical quantity (negative) entropy and the conceptual quantity
information. A strong formal connection between entropy and action arises
through the Euclidean, imaginary-time path integral formulation of partition
functions. Indeed, in that framework the expectation value of the Euclideanized
action essentially is the entropy. The identification of entropy with
Euclideanized action has been used, among other things, to motivate an
algebraically simple (but deeply mysterious "derivation" of black hole entropy.
If one could motivate the imaginary-time path integral directly and
insightfully, rather than indirectly through the apparatus of energy
eigenvalues, Boltzmann factors, and so forth, then one would have progressed
toward this general prediction of unification: Fundamental action principles,
and thus the laws of physics, will be re-interpreted as statements about
information and its transformations." http://arxiv.org/pdf/1503.07735v1.pdf
