"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!<br>
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." <a href="http://arxiv.org/pdf/1503.07735v1.pdf" rel="noreferrer" target="_blank">http://arxiv.org/pdf/1503.07735v1.pdf</a></blockquote><div><br></div><div>Great reference, and I agree with his prediction that laws of physics will be re-interpreted as statements about information and its transformations. Note that "information and its transformations" is another way of saying "computation" for computation is nothing besides information and its transformations. In the same paper, Wilczek saw that such a revision in physics would promote a sort of neutral monism, saying:</div></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div class="gmail_quote gmail_quote_container"><div>"If physics evolves to describe matter in terms of information, as we discussed earlier, a circle of ideas will have closed.

Observer mind states are computational. And the apparent physical universes seen by those observers are also computational. And because any given observer's mind state exists in a One-to-Many relationship with the physical universes that contain said mind state, the observer will see a reality that behaves as if it is part of a quantum multiverse, with parallel states that can branch or merge depending on information accessible to the observer's mind, with such branching events producing apparently random and unpredictable outcomes, which not even the laws the observer knows can predict. And this is exactly what we find with our own universe and its laws.</div><div><br></div></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div class="gmail_quote gmail_quote_container"><div>"It’s just our “parsing” of [everything] that defines the subject matter of what we call science.
