Q’anjob’al Language
Q'anjob'al (also Kanjobal) is a Mayan language spoken primarily in Guatemala and part of Mexico. According to 1998 estimates compiled by SIL International in Ethnologue, there were approximately 77,700 native speakers, primarily in the Huehuetenango Department of Guatemala. Municipalities where the Q'anjob'al language is spoken include San Juan Ixcoy (Yich K'ox), San Pedro Soloma (Tz'uluma' ), Santa Eulalia (Jolom Konob' ), Santa Cruz Barillas (Yalmotx), San Rafael La Independencia, and San Miguel Acatán (Pedro Mateo Pedro 2010). Q'anjob'al is taught in public schools through Guatemala's intercultural bilingual education programs.

Duality (Mathematics)
In mathematics, a duality translates concepts, theorems or mathematical structures into other concepts, theorems or structures, in a one-to-one fashion, often (but not always) by means of an involution operation: if the dual of A is B, then the dual of B is A. Such involutions sometimes have fixed points, so that the dual of A is A itself. For example, Desargues' theorem is self-dual in this sense under the standard duality in projective geometry. In mathematical contexts, duality has numerous meanings. It has been described as "a very pervasive and important concept in (modern) mathematics" and "an important general theme that has manifestations in almost every area of mathematics". Many mathematical dualities between objects of two types correspond to pairings, bilinear functions from an object of one type and another object of the second type to some family of scalars. For instance, linear algebra duality corresponds in this way to bilinear maps from pairs of vector spaces to scalars, the duality between distributions and the associated test functions corresponds to the pairing in which one integrates a distribution against a test function, and Poincaré duality corresponds similarly to intersection number, viewed as a pairing between submanifolds of a given manifold. From a category theory viewpoint, duality can also be seen as a functor, at least in the realm of vector spaces. This functor assigns to each space its dual space, and the pullback construction assigns to each arrow f: V → W its dual f∗: W∗ → V∗.

Cognitive Slippage
Cognitive slippage is considered a milder and sub-clinical presentation of formal thought disorder observed via unusual use of language. It is often identified when a person attempts to make tangential connections between concepts that are not immediately understandable to listeners. When observed repeatedly, this is taken as evidence for unusual, maladaptive or illogical thinking patterns. Cognitive slippage is typically assessed in the context of mental health evaluations, but there is ongoing debate about how to best quantify this type of unusual language usage in research settings. Cognitive slippage is supposed to exist on a continuum which can be observed in its most extreme forms among some individuals with schizophrenia (e.g., word salad). Several mental disorders are known to co-occur with cognitive slippage. Although cognitive slippage is associated with difficulties in communication, it is not necessarily indicative of lower intelligence.

Soyot
The Soyot people live mainly in the Oka region in the Okinsky District in the Republic of Buryatia, Russia . According to the 2010 census, there were 3,608 Soyots in Russia. Their extinct language was of a Turkic type and basically similar to the Tuvans. Their language has been reconstructed and a textbook has been published. The language is currently taught in some schools in Oka. The Oka River, the largest river flowing down from the Western Sayans into the Angara is called the Ok-hem meaning "an arrow-river" by the Soyots of the Oka River basin. They live dispersed among the Buryats and now speak the Buryat language.

Urban Legend
An urban legend, urban myth, urban tale, or contemporary legend is a genre of folklore comprising stories circulated as true, especially as having happened to a friend or family member, often with horrifying or humorous elements. These legends can be entertainment, but often concern mysterious peril or troubling events, such as disappearances and strange objects. They may also be confirmation of moral standards, or reflect prejudices, or be a way to make sense of societal anxieties. Urban legends are most often circulated orally, but can be spread by any media, including newspapers, e-mail and social media. Some urban legends have passed through the years with only minor changes to suit regional variations. Recent legends tend to reflect modern circumstances: for instance, the common legend of a person being ambushed and anesthetized, only to wake up and realize that they are now missing a kidney that was supposedly surgically removed for transplantation.

The Reverend
The Reverend is an honorific style most often placed before the names of Christian clergy and ministers. There are sometimes differences in the way the style is used in different countries and church traditions. The Reverend is correctly called a style but is often and in some dictionaries called a title, form of address or title of respect. The style is also sometimes used by leaders in non-Christian religions such as Judaism and Buddhism. The term is an anglicisation of the Latin reverendus, the style originally used in Latin documents in medieval Europe. It is the gerundive or future passive participle of the verb revereri ("to respect; to revere"), meaning "[one who is] to be revered/must be respected". The Reverend is therefore equivalent to The Honourable or The Venerable. It is paired with a modifier or noun for some offices in some religious traditions: Anglican archbishops and most Roman Catholic bishops are usually styled The Most Reverend (reverendissimus); other Anglican bishops and some Roman Catholic bishops are styled The Right Reverend; some Reformed churches have used The Reverend Mister as a style for their clergy. With Christian clergy, the forms His Reverence and Her Reverence is also sometimes used, along with its parallel in direct address, Your Reverence. The abbreviation HR is sometimes used.

Aether (Classical Element)
According to ancient and medieval science, aether (/ˈiːθər/), also spelled æther, aither, or ether and also called quintessence, is the material that fills the region of the universe above the terrestrial sphere. The concept of aether was used in several theories to explain several natural phenomena, such as the traveling of light and gravity. In the late 19th century, physicists postulated that aether permeated all throughout space, providing a medium through which light could travel in a vacuum, but evidence for the presence of such a medium was not found in the Michelson–Morley experiment, and this result has been interpreted as meaning that no such luminiferous aether exists.

Duration
Duration (French: la durée) is a theory of time and consciousness posited by the France philosopher Henri Bergson. Bergson sought to improve upon inadequacies he perceived in the philosophy of Herbert Spencer, due, he believed, to Spencer's lack of comprehension of mechanics, which led Bergson to the conclusion that time eluded mathematics and science. Bergson became aware that the moment one attempted to measure a moment, it would be gone: one measures an immobile, complete line, whereas time is mobile and incomplete. For the individual, time may speed up or slow down, whereas, for science, it would remain the same. Hence Bergson decided to explore the inner life of man, which is a kind of duration, neither a unity nor a quantitative multiplicity. Duration is ineffable and can only be shown indirectly through images that can never reveal a complete picture. It can only be grasped through a simple intuition of the imagination. Bergson first introduced his notion of duration in his essay Time and Free Will: An Essay on the Immediate Data of Consciousness. It is used as a defense of free will in a response to Immanuel Kant, who believed free will was only possible outside time and space.

Judeo-nazarenism
Judeo-nazarenism is a new term in the study of early Christianity. The term is distinguished from the term "Nazarenes" used in Jewish writings, to avoid the recognition of Jesus as Messiah, which is inherent in the term "Christians". It's also necessary to distinguish the various Christian sects who were using the name "Nazarenes" over the centuries.
