Facial Symmetry

	Facial Symmetry Facial symmetry is one specific measure of bodily symmetry. Along with traits such as averageness and youthfulness it influences judgments of aesthetic traits of physical attractiveness and beauty. For instance, in mate selection, people have been shown to have a preference for symmetry. Facial bilateral symmetry is typically defined as fluctuating asymmetry of the face comparing random differences in facial features of the two sides of the face. The human face also has systematic, directional asymmetry: on average, the face (mouth, nose and eyes) sits systematically to the left with respect to the axis through the ears, the so-called ''aurofacial asymmetry''. Directional asymmetry Directional asymmetry is a systematic asymmetry of some parts of the face across the population. A theory of directional asymmetries in the human body is the axial twist hypothesis. As predicted by this theory, the eyes, nose and mouth are, on average, located slightly to the left of the axis throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Symmetry Symmetry (from grc, συμμετρία "agreement in dimensions, due proportion, arrangement") in everyday language refers to a sense of harmonious and beautiful proportion and balance. In mathematics, "symmetry" has a more precise definition, and is usually used to refer to an object that is invariant under some transformations; including translation, reflection, rotation or scaling. Although these two meanings of "symmetry" can sometimes be told apart, they are intricately related, and hence are discussed together in this article. Mathematical symmetry may be observed with respect to the passage of time; as a spatial relationship; through geometric transformations; through other kinds of functional transformations; and as an aspect of abstract objects, including theoretic models, language, and music. This article describes symmetry from three perspectives: in mathematics, including geometry, the most familiar type of symmetry for many people; in science and nature ...

	Personality And Individual Differences ''Personality and Individual Differences'' is a peer-reviewed academic journal published 16 times per year by Elsevier. It was established in 1980 by Pergamon Press and is the official journal of the International Society for the Study of Individual Differences. The editors-in-chief are Peter K. Jonason, Julie Aitken Schermer, Aljoscha Neubauer, Michelle Yik and Colin Cooper. Previous editors include Donald H. Saklofske, Philip A. Vernon, Gísli Guðjónsson and Sybil B. G. Eysenck. The founding editor was Hans Jürgen Eysenck. The journal covers research about the structure of personality and other forms of individual differences, the processes which cause these individual differences to emerge, and their practical applications. Abstracting and indexing The journal is abstracted and indexed in: According to the ''Journal Citation Reports'', the journal has a 2021 impact factor of 3.951. Notable paper In 1985 the journal published "A revised version of the psychoticism scale" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Patterns In Nature Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes. Early Greek philosophers studied pattern, with Plato, Pythagoras and Empedocles attempting to explain order in nature. The modern understanding of visible patterns developed gradually over time. In the 19th century, the Belgian physicist Joseph Plateau examined soap films, leading him to formulate the concept of a minimal surface. The German biologist and artist Ernst Haeckel painted hundreds of marine organisms to emphasise their symmetry. Scottish biologist D'Arcy Thompson pioneered the study of growth patterns in both plants and animals, showing that simple equations could explain spiral growth. In the 20th century, the British mathematician Alan Turing predicted mechanisms of morphogenesis which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
