Orphan date April 2012 The Vienna Series in TheoreticalBiology is a book series published by MIT Press and devoted to advances in theoreticalbiology at large. By promoting the formulation and discussion of new theoretical concept s, the series intends to help fill the gaps in our understanding of some of the major open questions of biology , such as the origin and organization of organismal form, the relationship between Evolutionary developmental biology development and evolution , and the biological bases of cognition and mind . The Vienna Series grew out of the Altenberg Workshops in TheoreticalBiology organized by the Konrad Lorenz Institute for Evolution and Cognition Research KLI , an international center for advanced study in Altenberg, near Vienna , Austria . The KLI fosters research projects, workshops, archives, book projects, and the journal Biological Theory , all devoted to aspects of theoreticalbiology, with an emphasis on integrating the developmental, evolutionary, and cognitive sciences.

Orphan date February 2009 Refimprove date July 2007 Theoretical neuromorphology is the science of using Morphology biology morphology to mathematically describe the shape and the connectivity in the nervous system . History The rational study of shapes as been long to form. In the major progresses made during the last century, it is important to differentiate morphogenesis the way forms are made and morphology realized forms . Morphogenesis Important conceptual changes about forms came from d Arcy Thompson s essay 1917 dealing with forms in nature. These were not considered as static but as the result of morphogenetic factors. Not knowable in its intimate nature, form is defined as the simple result of forces. Ren Thom Thom 1974 , founder of the catastrophe theory acknowledged what he owed to this work. A series of various branches of non linear mathematics catastrophe theory , the fractal theory , the theory of dissipative structures , the chaos theory have led to what Boutot 1993 called the morphologic revolution , which has deeply modified the conception of forms in space.

Theoretical sampling refers to the process of choosing new research sites or cases to compare with ones that have already been studied. It is one of the tools of qualitative research . The term was coined by Barney Glaser and Anselm Strauss in 1967. The goal of theoretical sampling is not the same as with the sampling statistics probabilistic sampling the researcher s goal is not the representative capture of all possible variations, but to gain a deeper understanding of analysed cases and facilitate the development of analytic frame and concept s used in their research. Theoretical sampling can be viewed as a technique of data triangulation using independent pieces of information to get a better fix on something that is only partially known or understood.

The division of philosophy into a practical philosophy practical and a theoretical discipline has its origin in Aristotle s moral philosophy and natural philosophy categories. In Denmark , Finland , Poland , and Sweden courses in theoretical and practical philosophy are taught separately, and are separate degrees. Other countries may use a similar scheme some Scotland Scottish universities, for example, divide philosophy into logic , metaphysics , and ethics but in most universities around the world philosophy is taught as a single subject. There is also a unified philosophy subject in some Swedish universities, such as S dert rn University College S dert rns H gskola . Theoretical philosophy is sometimes confused with Analytic philosophy , but the latter is a philosophical movement, embracing certain ideas and methods but dealing with all philosophical subject matters, while the former is a way of sorting philosophical questions into two different categories in the context of a curriculum .

For the journal Theoretical Linguistics journal Theoretical linguistics is the branch of linguistics that is most concerned with developing models of linguistic knowledge. The fields that are generally considered the core of theoretical linguistics are syntax , phonology , morphology linguistics morphology , and semantics . Although phonetics often informs phonology, it is often excluded from the purview of theoretical linguistics, along with psycholinguistics and sociolinguistics . Theoretical linguistics also involves the search for an explanation of linguistic universal s, that is, properties all language s have in common. Linguistics Major fields See grammar formal grammar grammar framework Phonetics Expand section date May 2008 Phonetics is the study of speech sounds with concentration on three main points Articulation the production of speech sounds in human speech organs. Perception the way human ears respond to speech signals, how the human brain analyses them. Acoustic features physical characteristics of speech sounds such as color, loudness , amplitude , frequency etc. According to this definition, phonetics can also be called linguistic analysis of human speech at the surface level. That is one obvious difference from phonology , which concerns the structure and organisation of speech sounds in natural languages, and furthermore has a theoretical and abstract nature. One example can be made to illustrate this distinction In English, the suffix s can represent either IPA s , IPA z , or can be silent written depending on context. Orthographic representation S, s Phonetic features Phonetic representations IPA s , IPA z , Perception through the ear high frequency sounds accompanied by a hissing noise.

no footnotes date November 2011 In geodesy and geophysics , theoretical gravity is a means to compare the true gravity on the Earth s surface with a physically smoothed model. The most common model of a smoothed Earth is the Earth ellipsoid . Despite of the fact that the exact density layers in the Earth s interior are still unknown, the theoretical gravity g of its level surface can be computed by a relative simple formula, which is called the International Gravity Formula . It refers to a mean Earth ellipsoid , the parameters of which are set by international convention. It shows the gravity at a smoothed Earth s surface as a function of geographic latitude &phi the actual formula is math g phi left 9.780327 0.0516323 sin 2 phi 0.0002269 sin 4 phi right , frac mathrm m mathrm s 2 math The term 0.0516323 is called gravity flattening abbreviated &beta . As a physically defined form parameter it corresponds to the geometrical flattening f of the earth ellipsoid. Up to the 1960s, the formula either of the Hayford ellipsoid 1924 or of the famous German geodesist Helmert 1906 was used. Hayford has an axis difference clarify reason Do you mean the position of the axis of symmetry? date October 2011 to modern values of val 250 u m , Helmert only val 70 u m . The Helmert formula is math g phi left 9.8061999 0.0259296 cos 2 phi 0.0000567 cos 2 2 phi right , frac mathrm m mathrm s 2 math A slightly different formula for g as a function of latitude is the WGS World Geodetic System 1984 Ellipsoidal gravity formula Gravity Formula math g phi left 9.7803267714 frac 1 0.00193185138639 sin 2 phi sqrt 1 0.00669437999013 sin 2 phi right , frac mathrm m mathrm s 2 math The difference between the WGS 84 formula and Helmert s equation is less than 0.68 ppm or val 6.8 e 7 u m s sup 2 sup .

Unreferenced stub date December 2009 Orphan date December 2009 Alternative biology is the study of theoretical or non traditional life forms such as acellular life , Hypothetical types of biochemistry non carbon based life , extraterrestrial life , cyborg cyborg life , or artificial life . It also considers the earliest theoretical forms of life on Earth, such as RNA world hypothesis RNA life or Iron sulfur world theory iron sulfur life which may have been the ur organism earliest organisms . Known biological entities which may not always be considered life may also be considered in alternative biology such as virus es and plasmid s.
