This theory proceeds from the idea of atomic valence, especially the tetravalence of carbon ( which Kekulé announced late in 1857 ) and the ability of carbon atoms to link to each other ( announced in a paper published in May 1858 ), to the determination of the bonding order of all of the atoms in a molecule.

Adorno's theory proceeds from an understanding of this primitive quality of reality which seeks to counteract whatever aims to either repress this primitive aspect or further those systems of domination set in place by this return to barbarism.

Traditional probability theory does not state if a specific sequence is random, but generally proceeds to discuss the properties of random variables and stochastic sequences assuming some definition of randomness.

Freud explains that " the associated theory of magic merely explains the paths along which magic proceeds ; it does not explain its true essence, namely the misunderstanding which leads it to replace the laws of nature by psychological ones ".

Honing theory posits that creative thought proceeds not by searching through and randomly ‘ mutating ’ predefined possibilities, but by drawing upon associations that exist due to overlap in the distributed neural cell assemblies that participate in the encoding of experiences in memory.

In the simplest theory for detonations, an unsupported, self-propagating detonation wave proceeds at the Chapman-Jouguet velocity.

Having made it clear that idealism depends upon postulates and proceeds hypothetically, Royce defends the necessity of objective reference of our ideas to a universal whole within which they belong, for without these postulates, “ both practical life and the commonest results of theory, from the simplest impressions to the most valuable beliefs, would be for most if not all of us utterly impossible .” ( see The Religious Aspect of Philosophy, p. 324 ) The justification for idealistic postulates is practical ( a point Royce made repeatedly in his maturity, accepting the label of " pragmatist " for himself, to the extent that it embraced practical life as the guide and determiner of the value of philosophical ideas.

The second, less popular theory is the top-to-bottom model which says that skin first begins to deteriorate at the surface and then proceeds inward.

In mathematics, the derived category D ( C ) of an abelian category C is a construction of homological algebra introduced to refine and in a certain sense to simplify the theory of derived functors defined on C. The construction proceeds on the basis that the objects of D ( C ) should be chain complexes in C, with two such chain complexes considered isomorphic when there is a chain map that induces an isomorphism on the level of homology of the chain complexes.

The Beilinson-Bernstein-Deligne definition of a perverse sheaf proceeds through the machinery of triangulated categories in homological algebra and has very strong algebraic flavour, although the main examples arising from Goresky-MacPherson theory are topological in nature.

Harsanyi and Sen thus argue that at least partial comparability of utility is possible, and social-choice theory proceeds under that assumption.

From the beginning of Communist rule in 1949, until the 1980s, when China was in the early years of economic reform, the focus was largely on peasant life, as interpreted via the officially sanctioned Marxist theory of class struggle.

To use an epistemological distinction introduced by Jürgen Habermas in Erkenntnis und Interesse ( Knowledge and Human Interests ), critical theory in literary studies is ultimately a form of hermeneutics, i. e. knowledge via interpretation to understand the meaning of human texts and symbolic expressions — including the interpretation of texts which are themselves implicitly or explicitly the interpretation of other texts.

He is known for his scientific contributions to theory of chemical equilibria via the mechanism of reverse chemical reactions, and for his contribution to modern chemical nomenclature.

Books V and VII – X deal with number theory, with numbers treated geometrically via their representation as line segments with various lengths.

Ephemeris time was a first application of the concept of a dynamical time scale, in which the time and time scale are defined implicitly, inferred from the observed position of an astronomical object via the dynamical theory of its motion.

The interrelationships between volume change behavior ( dilation, contraction, and consolidation ) and shearing behavior were all connected via the theory of plasticity using critical state soil mechanics by Roscoe, Schofield, and Wroth with the publication of " On the Yielding of Soils " in 1958.

The study of field extensions ( and polynomials which give rise to them ) via Galois groups is called Galois theory, so named in honor of Évariste Galois who first discovered them.

Weitzenhoffer describes hypnosis via this theory as " dissociation of awareness from the majority of sensory and even strictly neural events taking place.

Research has led to a dispersal via land bridge-based theory, and scientists have gone on to note the waves of adaptive radiation that seem to have swept the Americas from north to south.

The theory of automorphic forms, an important branch of modern number theory, deals extensively with analogues of Lie groups over adele rings ; p-adic Lie groups play an important role, via their connections with Galois representations in number theory.

This paradox is explained by the fact that the Big Bang theory also involves the expansion of space which can cause the energy of emitted light to be reduced via redshift.

Diverse systems with the same critical exponents — that is, which display identical scaling behaviour as they approach criticality — can be shown, via renormalization group theory, to share the same fundamental dynamics.

According to Stephen Metcalf, Nozick expresses serious misgivings about capitalist libertarianism, going so far as to reject much of the foundations of the theory on the grounds that personal freedom can sometimes only be fully actualized via a collectivist politics and that wealth is at times justly redistributed via taxation to protect the freedom of the many from the potential tyranny of an overly selfish and powerful few.

Other approaches to reaching a decision based on data are available via decision theory and optimal decisions.

The theory of evolution states that species change over time via mutation and sexual reproduction.

The theory of special relativity predicts that any such device would allow communication from the future to the past, which raises problems of causality, unless the device used general relativistic curved spacetimes as an integral part.

Another recent theory ( see EPR paradox above ) resulting from the analysis of an EPR communication set up, has the simple device based on removing the effective retarded time terms in the Lorentz transform to yield a preferred absolute reference frame.

In theory the microkernel design would allow for all device drivers to be built as servers working in user space, but today most drivers of this kind are still contained in the GNU Mach kernel space.

R. Hilsch and R. W. Pohl in 1938 demonstrated a solid-state amplifier using a structure resembling the control grid of a vacuum tube ; although the device displayed power gain, it had a cut-off frequency of one cycle per second, too low for any practical applications, but an effective application of the available theory.

The SCSI standard defines command sets for specific peripheral device types ; the presence of " unknown " as one of these types means that in theory it can be used as an interface to almost any device, but the standard is highly pragmatic and addressed toward commercial requirements.

In this respect, with the possibility of misinterpretations, von Bertalanffy believed a general theory of systems " should be an important regulative device in science ," to guard against superficial analogies that " are useless in science and harmful in their practical consequences.

In keeping with these points, James Hurford argues that the postulate of a language acquisition device ( LAD ) essentially amounts to the trivial claim that languages are learnt by humans, and thus, that the LAD is less a theory than an explanandum looking for theories.

Constellations are an astronomical device for handling observation and precision independent of current physical theory or interpretation.

* challenge ( or even refute ) a prevailing theory, often involving the device known as reductio ad absurdum, ( as in Galileo's original argument, a proof by contradiction ),

Thus, for the de Broglie – Bohm theory, the particle's spin is not an intrinsic property of the particle — instead spin is, so to speak, in the wave function of the particle in relation to the particular device being used to measure the spin.
