Physical Information - Extreme Physical Information

Extreme Physical Information

According to a theory developed by B. Roy Frieden, "physical information" can be defined to be the loss of Fisher information that is incurred during the observation of a "physical effect".

Frieden states, if the effect has an intrinsic information level J, and is observed with information level I, then the physical information is defined to be the difference IJ, which Frieden calls the information Lagrangian. Frieden's so-called principle of extreme physical information or EPI states that extremalizing IJ with respect to variation of the system probability amplitudes can be used the correct Lagrangians for most or even all physical theories.

    Blaise Pascal (1623–1662)

    As information technology restructures the work situation, it abstracts thought from action.
