	Generalizability Theory
		G theory reinterprets classical reliability theory as a theory regarding the adequacy with which one can generalize from a sample of observations to a universe of observations from which it was randomly sampled.
		G theory defines observations as dependable if they permit accurate inferences about the latent construct (i.e., the universe of admissible observations) they are meant to represent.
		G theory can also be applied to the analysis of score profiles, composites, and difference scores, and extensions have been developed to estimate variance components via maximum likelihood, Bayesian, and covariance structure methods and for studying the dependability of any facet of observation.

	Theory G.
		According to the theory, magnetism in its "free" state, (i.e., untethered to matter), exists in the trans-light state as a kind of standing wave...
		In other words, the mass of that smallest particle will vary across the universe, dependent on the mass of the "parent body" of which it is a part, but will be a constant within any one such "parent body" -- that constant being about 10^-39 the mass of the parent body.
		By the term "parent body" I'm referring to the theory's suggestion that matter comes into existence in "clumps" which are rarely less massive than a galaxy, or more massive than a galactic cluster.

	VI: Why demographers need theory, by G. Wunsch
		Theories, laws, and explanation Demographers do not usually proceed by asking for example what are all the causes, both proximate, intermediate, and ultimate, of mortality in contemporary Europe.
		Theories can therefore change over time and space, and differ from one scientist to the other; as always, the proof of the pudding is in the eating, i.e.
		Theory enables the scientist to select a small sub-set of possible structures or ®possible worlds¯ (usually only one) from the many which can be proposed with the variables on hand.

	Kuratowski's Introduction to Set Theory
		The object of set theory is to investigate the properties of sets from the most general point of view; generality is an essential aspect of the theory of sets.
		The stimulus to the investigations from which the theory of sets grew, was given by problems of analysis, the establishing of the foundations of the theory of irrational numbers, the theory of trigonometric series, etc, However, the further development of set theory went initially in an abstract direction, little connected with other branches of mathematics.
		This fact, together with a certain strangeness of the methods of set theory which were entirely different from those applied up to that time, caused many mathematicians to regard this new branch of mathematics initially with a certain degree of distrust and reluctance.

	Truth, Prosentential Theory of [Internet Encyclopedia of Philosophy]
		The correspondence theory claims that snow’s being white is necessary but not sufficient for the truth of ‘snow is white.’ In addition to snow’s being white, the proposition that snow is white must stand in a relation of correspondence to the fact that snow is white.
		The prosentential theory of truth can be extended to account for uses of the predicate ‘x is false.’ The prosentential theory of falsity will be strongly analogous to the prosentential theory of truth.
		The prosentential theory explains that any referring expression (e.g., a name, definite description, etc.) inherits its content from its anaphoric antecedent(s) and, when such an expression is conjoined to the truth predicate, a prosentence with the same content as the antecedent(s) results.

	Quantum Field Theory (Stanford Encyclopedia of Philosophy)
		Second, due to the development of QFT and of the theory of superstrings in the last two decades the initial hope is fading away that QFT is near to its final completion and this fact speaks against a further postponement of philosophical analyses of QFT.
		Despite of the problems of string theory, physicists do not abandon this project, partly because there seem to be no better candidates for a reconciliation of quantum physics and general relativity theory with the possible exception of the so-called “loop quantum gravity” (see the entry on quantum gravity).
		A relativistic quantum theory of a fixed number of particles, satisfying in particular the localizability and the locality condition, has to assume a world devoid of particles (or at least a world in which particles can never be detected) in order not to contradict itself.

	TIP: Theories
		The concept of chunking and the limited capacity of short term memory became a basic element of all subsequent theories of memory.
		In a TOTE unit, a goal is tested to see if it has been achieved and if not an operation is performed to achieve the goal; this cycle of test-operate is repeated until the goal is eventually achieved or abandoned.
		Information processing theory has become a general theory of human cognition; the phenomenon of chunking has been verified at all levels of cognitive processing.

	NOVA \| The Elegant Universe \| Watch the Program (full-screen) \| PBS
		String theory is radically changing our ideas about the nature of space, opening up the possibility that extra dimensions, rips in the fabric of space, and parallel universes actually exist.
		The extra dimension of space required to unify string theory suggests that we may be trapped on just one tiny slice of a higher-dimensional universe.
		By the mid-1980s physicists had developed five different versions of string theory, raising the question of whether it would prove to be a theory of everything or a theory of nothing.

	International Relations Theory (Site not responding. Last check: 2007-10-09)
		But all empirical theories share in common the fact that they are NOT evaluating policies or governmental action as good or bad; they are simply attempting to understand the reality of what exists.
		All of the theories we will examine are really not one theory but a category or type of theories with some important internal debates among sub-theories.

	TIP: Theories
		The Conversation Theory developed by G. Pask originated from a cybernetics framework and attempts to explain learning in both living organisms and machines.
		The fundamental idea of the theory was that learning occurs through conversations about a subject matter which serve to make knowledge explicit.
		The critical method of learning according to conversation theory is "teachback" in which one person teaches another what they have learned.

	Category Theory (Stanford Encyclopedia of Philosophy)
		It could be argued that category theory represents the culmination of one of deepest and most powerful tendencies in twentieth century mathematical thought: the search for the most general and abstract ingredients in a given situation.
		Still, it remains to be seen whether category theory should be "on the same plane," so to speak, as set theory, whether it should be taken as a serious alternative to set theory as a foundation for mathematics, or whether it is foundational in a different sense altogether.
		From the foregoing disussion, it should be obvious that category theory and categorical logic ought to have an impact on almost all issues arising in philosophy of logic: from the nature of identity criteria to the question of alternative logics, category theory always sheds a new light on these topics.

	12: Field theory and polynomials
		The study of multiple fields through Galois theory is important for the study of polynomial equations, and thus has applications to number theory and group theory.
		By applying results in Model Theory to these axioms one may construct non-standard models of the real field, leading to Non-Standard Analysis (in which, in particular, arguments of calculus can be carried out with reference to epsilons but not limits!).
		Until section Number Theory was reorganized (in 1984) from section 10 to section 11, some of the topics now considered number theory were classified with section 12.

		Systems Theory: the transdisciplinary study of the abstract organization of phenomena, independent of their substance, type, or spatial or temporal scale of existence.
		Systems analysis, developed independently of systems theory, applies systems principles to aid a decisIon-maker with problems of identifying, reconstructing, optimizing, and controlling a system (usually a socio-technical organization), while taking into account multiple objectives, constraints and resources.
		Systems theory is closely connected to cybernetics, and also to system dynamics, which models changes in a network of coupled variables (e.g.

	20: Group Theory and Generalizations
		Group theory can be considered the study of symmetry: the collection of symmetries of some object preserving some of its structure forms a group; in some sense all groups arise this way.
		In addition, there is to be an element '1' in G with 1g=g1=g for every g in G; and every element g in G must have an inverse h satisfying gh=hg=1.
		Representation theory also considers images of groups in the automorphism groups of other abelian groups than simply complex vector spaces; these then are the group modules.

		This revolutionary vision is able not only to explain all of the phenomena that the Theory of Relativity can explain, but also, a host of other scientific conundrums such as: the explanation of Sir Isaac Newton’ s three laws of motion; Young’s famous two slit experiment; and the explanation of the Pauli Exclusion Principle.

		Starting with the unique factorization property of the integers, the theme of factorization is revisited several times throughout the book to illustrate how the ideas handed down from Euclid continue to reverberate through the subject.
		The result is that number theory will be understood, not as a collection of tricks and isolated results, but as a coherent and interconnected theory.
		A number of different approaches to number theory are presented, and the different streams in the book are brought together in a chapter that describes the class number formula for quadratic fields and the famous conjectures of Birch and Swinnerton-Dyer.

	G.L.S. Shackle
		A pioneering Post Keynesian, he was among the first economists to insist on the importance of "real" uncertainty and time for economic theory.
		His work on uncertainty focused on moving away from probability- based resultions for uncertain situations and moving towards more complex modes of behavior which include "potential surprise", "focus-outcome" of competing choices, much of it linked to uncertainty-induced demand failures.
		Two of his works on doctrinal economic history have become classics: his Years of High Theory detailing the economic debates surrounding the Keynesian Revolution in Britain are invaluable as is his Epistemtics and Economics, an incisive critical evaluation of various economic theories.

	Graph Theory
		For a set of vertices X, we use G[X] to denote the induced subgraph of G whose vertex set is X and whose edge set is the subset of E(G) consisting of those edges with both ends in X.
		For a set S of edges, we use G[S] to denote the edge induced subgraph of G whose edge set is S and whose vertex set is the subset of V(G) consisting of those vertices incident with any edge in S.
		A graph G has connectivity k if G is k-connected but not (k+1)-connected.

	FOM: Wheter G.Cantor's set theory is naive?
		But I am sure that none of professionals in that areas of modern mathematics will be consenting to such the "naive" definition and valuation of his/her activity area.
		In my opinion, there are, at least, two principal differences between meta-matematical formal systems and physical theories (in the form of their formal mathematical models).
		Since any axiomatic set theory, without G.Cantor's Theorem on the uncountability, is not a very interesting theory, and since that G.Cantor's Theorem itsef becomes invalid and loses its sense without the actual infinity, it can be stated that all modern meta-mathematics is strongly based upon just such the "naive" notion as the ACTUAL infinity.

	N›g›rjuna’s theory of Causality:
		A Madhyamaka answer to questions of the first kind is a straightforward catholic realism: Accept the deficits of economics, the kinship relations of anthropology, the classes of sociology, the beliefs of psychology, the molecules of chemistry, the niches of ecology and the quarks of physics.
		These issues are particularly sharp in cognitive science, where naturalistic, intentional explanations vie with eliminative and cognitive neuroscience, nonlinear dynamic theory, computational models, etc… Now many of these debates are straightforwardly empirical debates about how best to understand a particular cognitive phenomenon, and about whether a particular theory is, on its own terms, successful.
		While a theory about causation—even a pre-reflective theory—might seem to be but a recherché corner of metaphysics and the philosophy of science, it in fact infects and determines our view of everything else—from the philosophy of science to the philosophy of mind to cosmology to ethics.
