Optical Illusion
Within visual perception, an optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual perception, percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions. A classical example for a physical distortion would be the apparent bending of a stick half immerged in water; an example for a physiological paradox is the motion aftereffect (where, despite movement, position remains unchanged). An example for a physiological fiction is an afterimage. Three typical cognitive distortions are the Ponzo illusion, Ponzo, Poggendorff illusion, Poggendorff, an ...

Spiritualism
Spiritualism is the metaphysical school of thought opposing physicalism and also is the category of all spiritual beliefs/views (in monism and dualism) from ancient to modern. In the long nineteenth century, Spiritualism (when not lowercase) became most known as a social religious movement according to which the laws of nature and of God include "the continuity of consciousness after the transition of death" and "the possibility of communication between those living on Earth and those who have made the transition". The afterlife, or the " spirit world", is seen by spiritualists not as a static place, but as one in which spirits continue to evolve. These two beliefs—that contact with spirits is possible, and that spirits are more advanced than humans—lead spiritualists to a third belief: that spirits are capable of providing useful insight regarding moral and ethical issues, as well as about the nature of God. Some spiritualists will speak of a concept which they refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asterisk
The asterisk ( ), from Late Latin , from Ancient Greek , ''asteriskos'', "little star", is a typographical symbol. It is so called because it resembles a conventional image of a heraldic star. Computer scientists and mathematicians often vocalize it as star (as, for example, in ''the A* search algorithm'' or ''C*-algebra''). In English, an asterisk is usually five- or six-pointed in sans-serif typefaces, six-pointed in serif typefaces, and six- or eight-pointed when handwritten. Its most common use is to call out a footnote. It is also often used to censor offensive words. In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, or multiplication.
