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 I − J, which Frieden calls the information Lagrangian. Frieden's so-called principle of extreme physical information or EPI states that extremalizing I − J with respect to variation of the system probability amplitudes can be used the correct Lagrangians for most or even all physical theories.

Famous quotes containing the words extreme, physical and/or information:
“The melancholy of having to count souls
Where they grow fewer and fewer every year
Is extreme where they shrink to none at all.
It must be I want life to go on living.”
—Robert Frost (1874–1963)
“Patience, that blending of moral courage with physical timidity.”
—Thomas Hardy (1840–1928)
“Phenomenal nature shadows him wherever he goes. Clouds in the staring sky transmit to one another, by means of slow signs, incredibly detailed information regarding him. His inmost thoughts are discussed at nightfall, in manual alphabet, by darkly gesticulating trees. Pebbles or stains or sunflecks form patterns representing in some awful way messages which he must intercept. Everything is a cipher and of everything he is the theme.”
—Vladimir Nabokov (1899–1977)
