extreme physical information
Extreme physical information (EPI) is a principle, first described and formulated in 1998〔B. Roy Frieden, ''Physics from Fisher Information: A Unification '', 1st Ed. Cambridge University Press, ISBN 0-521-63167-X, pp328, 1998 ((name="Frieden6" ) shows 2nd Ed.)〕 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 ==
Physicist John Archibald Wheeler stated that:
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, biology, the biophysics of cancer growth,chemistry,〔 and economics. 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.
