Extreme physical information

Extreme physical information (EPI) is a principle, first described and formulated in 1998[1] by B. Roy Frieden, Emeritus Professor of Optical Sciences at the University of Arizona, that states, the precipitation of scientific laws can be derived through Fisher information, taking the form of differential equations and probability distribution functions.

Introduction[edit]

Physicist John Archibald Wheeler stated that:

All things physical are information-theoretic in origin and this is a participatory universe... Observer participancy gives rise to information; and information gives rise to physics.

By using Fisher information, in particular its loss I - J incurred during observation, the EPI principle provides a new approach for deriving laws governing many aspects of nature and human society. EPI can be seen as an extension of information theory that encompasses much theoretical physics and chemistry. Examples include the Schrödinger wave equation and the Maxwell–Boltzmann distribution law. EPI has been used to derive a number of fundamental laws of physics,[2][3] biology,[4] the biophysics of cancer growth,[5]chemistry,[5] and economics.[6] EPI can also be seen as a game against nature, first proposed by Charles Sanders Peirce. The approach does require prior knowledge of an appropriate invariance principle or data.

EPI principle[edit]

The EPI principle builds on the well known idea that the observation of a "source" phenomenon is never completely accurate. That is, information present in the source is inevitably lost when observing the source. Moreover, the random errors that contaminate the observations are presumed to define the probability distribution function of the source phenomenon. That is, "the physics lies in the fluctuations." The information loss is postulated to be an extreme value. Thus, if the Fisher information in the data is \mathcal{I}, and the Fisher information in the source is \mathcal{J}, the EPI principle states that:


\mathcal{I}
-
\mathcal{J}
=
\mathrm {Extremum}

The extremum for most situations is a minimum, meaning that there is a comforting tendency for any observation to describe its source faithfully.
