	Fisher Information
		The book "Science from Fisher Information" is the main reference for the approach (see reference [1b] in list at end).
		Unfortunately, there is a downside to information, and that is misinformation.
		The latter three fields are usually regarded as exterior to physics, hence the name change of the book to "Science from Fisher Information." That is, most generally, science follows from the use of Fisher information.

	Fisher information - Wikipedia, the free encyclopedia
		The Fisher information is thus the expectation of the square of the score.
		Thus Fisher information is the expectation of the second derivative of the log of f with respect to θ.
		Information may thus be seen to be a measure of the "sharpness" of the support curve near the maximum likelihood estimate of θ.

	Living with Fisher in Massachusetts
		The fisher prefers wooded habitat and was once extirpated from Massachusetts due to agricultural land clearing that virtually eliminated their forest habitat.
		The fisher is one of the largest members of the Mustelid family, which includes the weasels, mink, otter, and skunk.
		Fishers reach sexual maturity at 1 year of age and females produce their first litter at the age of 2.

		Information is a term with many meanings depending on context, but is as a rule closely related to such concepts as meaning, knowledge, instruction, communication, representation, and mental stimulus.
		Although many people speak of the advent of the "information age," the "information society," and information technologies, and even though information science and computer science are often in the spotlight, the word "information" is often used without careful consideration of the various meanings it has come to acquire.
		Information is a message, something to be communicated from the sender to the receiver, as opposed to noise, which is something that inhibits the flow of communication or creates misunderstanding.

	Fisher information metric - Wikipedia, the free encyclopedia
		In mathematics, in information geometry, the Fisher information metric is a metric tensor for a statistical differentiable manifold.
		It can be used to calculate the informational difference between measurements.

	Phil Fisher biographical information at Fisher Books
		Born in San Francisco in 1907, Philip Fisher was one of the first investment "philosophers" to focus almost exclusively on qualitative and growth factors.
		Philip Fisher was the first to contribute an analytical framework within which to judge a growth stock and contemplate its potential in growth instead of just price trends and absolute value.
		Philip A. Fisher passed away in San Mateo, CA in March 2004 at the age of 96.

	B. Roy Frieden, Physics from Fisher Information
		Fisher information is a quantity devised by the great statistician R. Fisher in the 1920s, which is supposed to tell us how easy it is to learn about a probability distribution by sampling from it.
		Then the Fisher information, with respect to t, is the mean value of the square of the ratio between the derivative of p with respect to t and p itself --- I = <(dp(x;t)/dt 1/p(x;t))^2>, in the rather clunky symbols HTML allows.
		To get that, he subtracts from the Fisher information a new quantity of his own devising, the "bound information," and requires that the difference between these two, which he calls the "physical information," have stationary variation.

		Exergy, a thermodynamically based index, is a measure of the maximum amount of useable work that can be extracted when a system is brought into equilibrium with a reference state.
		Fisher Information is an old statistical measure that has recently been applied as a way to detect change in system regime and as a measure of system order.
		The results show that generally, although not always, exergy and Fisher Information respond differently, such that when one increases due to a perturbation the other decreases and vice versa.

	Fisher information in quantum statistics
		They showed that the quantum information is nothing other than the maximal Fisher information in a measurement of the quantum system, maximized over all possible measurements.
		Combining this fact with classical statistical results, they argued that the quantum information determines the asymptotically optimal rate at which neighbouring states on some smooth curve can be distinguished, based on arbitrary measurements on n identical copies of the given quantum system.
		We show that the measurement which maximizes the Fisher information typically depends on the true, unknown, state of the quantum system.
