In physics, a physical body or physical object (or simply a body or object) is an identifiable collection of matter, which may be constrained by an identifiable boundary, and may move as a unit by translation or rotation, in 3-dimensional space. In common usage, an object is a collection of matter within a defined contiguous boundary in 3-dimensional space. The boundary must be defined and identified by the properties of the material. The boundary may change over time. The boundary is usually the visible or tangible surface of the object. The matter in the object is constrained (to a greater or lesser degree) to move as one object. The boundary may move in space relative to other objects that it is not attached to (through translation and rotation). An object's boundary may also deform and change over time in other ways. Also in common usage, an object is not constrained to consist of the same collection of matter. Atoms or parts of an object may change over time. An object is defined by the simplest representation of the boundary consistent with the observations. However the laws of Physics only apply directly to objects that consist of the same collection of matter. Each object has a unique identity, independent of any other properties. Two objects may be identical, in all properties except position, but still remain distinguishable. In most cases the boundaries of two objects may not overlap at any point in time. The property of identity allows objects to be counted. Examples of models of physical bodies include, but are not limited to a particle, several interacting smaller bodies (particles or other), and continuous media. The common conception of physical objects includes that they have extension in the physical world, although there do exist theories of quantum physics and cosmology which may challenge this. In modern physics, "extension" is understood in terms of the spacetime: roughly speaking, it means that for a given moment of time the body has some location in the space, although not necessarily a point. A physical body as a whole is assumed to have such quantitative properties as mass, momentum, electric charge, other conserving quantities, and possibly other quantities. A body with known composition and described in an adequate physical theory is an example of physical system.

The Restoration Movement (also known as the American Restoration Movement or the Stone-Campbell Movement, and pejoratively as Campbellism) is a Christian movement that began on the United States frontier during the Second Great Awakening (1790–1840) of the early 19th century. The pioneers of this movement were seeking to reform the church from within and sought "the unification of all Christians in a single body patterned after the church of the New Testament.":54 Especially since the mid-20th century, members of these churches do not identify as Protestant but simply as Christian.:213 The Restoration Movement developed from several independent strands of religious revival that idealized early Christianity. Two groups, which independently developed similar approaches to the Christian faith, were particularly important. The first, led by Barton W. Stone, began at Cane Ridge, Kentucky, and identified as "Christians". The second began in western Pennsylvania and Virginia (now West Virginia) and was led by Thomas Campbell and his son, Alexander Campbell, both educated in Scotland; they eventually used the name "Disciples of Christ". Both groups sought to restore the whole Christian church on the pattern set forth in the New Testament, and both believed that creeds kept Christianity divided. In 1832 they joined in fellowship with a handshake. Among other things, they were united in the belief that Jesus is the Christ, the Son of God; that Christians should celebrate the Lord's Supper on the first day of each week; and that baptism of adult believers by immersion in water is a necessary condition for salvation. Because the founders wanted to abandon all denominational labels, they used the biblical names for the followers of Jesus.:27 Both groups promoted a return to the purposes of the 1st-century churches as described in the New Testament. One historian of the movement has argued that it was primarily a unity movement, with the restoration motif playing a subordinate role.:8 The Restoration Movement has since divided into multiple separate groups. There are three main branches in the U.S.: the Churches of Christ, the unaffiliated Christian Church/Church of Christ congregations, and the Christian Church (Disciples of Christ). Some characterize the divisions in the movement as the result of the tension between the goals of restoration and ecumenism: the Churches of Christ and unaffiliated Christian Church/Church of Christ congregations resolved the tension by stressing restoration, while the Christian Church (Disciples of Christ) resolved the tension by stressing ecumenism.:383 A number of groups outside the U.S. also have historical associations with this movement, such as the Evangelical Christian Church in Canada and the Churches of Christ in Australia. Because the Restoration Movement lacks any centralized structure, having originated in a variety of places with different leaders, there is no consistent nomenclature for the movement as a whole. The term "Restoration Movement" became popular during the 19th century; this appears to be due to the influence of Alexander Campbell's essays on "A Restoration of the Ancient Order of Things" in the Christian Baptist. The term "Stone-Campbell Movement" emerged towards the end of the 20th century as a way to avoid the difficulties associated with some of the other names that have been used, and to maintain a sense of the collective history of the movement.

Bhartṛhari (Devanagari: भर्तृहरि; also romanised as Bhartrihari; fl. c. 5th century CE) is a Sanskrit writer to whom are normally ascribed two influential Sanskrit texts: In the medieval tradition of Indian scholarship, it was assumed that both texts were written by the same person. Modern philologists were sceptical of this claim, owing to an argument that dated the grammar to a date subsequent to the poetry. Since the 1990s, however, scholars have agreed that both works may indeed have been contemporary, in which case it is plausible that there was only one Bhartrihari who wrote both texts. Both the grammar and the poetic works had an enormous influence in their respective fields. The grammar in particular, takes a holistic view of language, countering the compositionality position of the Mimamsakas and others. The poetry constitute short verses, collected into three centuries of about a hundred poems each. Each century deals with a different rasa or aesthetic mood; on the whole his poetic work has been very highly regarded both within the tradition and by modern scholarship. The name Bhartrihari is also sometimes associated with Bhartrihari traya Shataka, the legendary king of Ujjaini in the 1st century.

Devil in Christianity
The Devil in Christianity is the personification of evil and author of sin, who rebelled against God in an attempt to become equal to God himself.[lower-alpha 1] He is depicted as a fallen angel, who was expelled from Heaven at the beginning of time, before God created the material world, and is in constant opposition to God. The devil is identified with several figures in the Bible including the serpent in the Garden of Eden, Lucifer, Satan, the tempter of the Gospels, Leviathan, and the dragon in the Book of Revelation. Early scholars discussed the role of the devil. Scholars influenced by neoplatonic cosmology, like Origen and Pseudo-Dionysius, portrayed the devil as representing deficiency and emptiness, the entity most remote from the divine. According to Augustine of Hippo the realm of the devil is not nothingness, but an inferior realm standing in opposition to God. The standard Medieval depiction of the devil was set up by Gregory the Great. He integrated the devil, as the first creation of God, into the Christian angelic hierarchy as the highest of the angels (either a cherub or a seraph). But as high as he stood in heaven, so far he fell into the depths of hell and became the leader of demons. Since the early reformation period, the devil was imagined as an increasingly powerful entity, with not only a lack of goodness but also a conscious will against God, his word, and his creation. Simultaneously, some reformists interpreted the devil as a mere metaphor for human's inclination to sin and so downgraded the importance of the devil. While the devil played for most scholars no significant role in the Modern Era, he became more important in contemporary Christianity again. At various times in history, some people such as the Cathars and the Bogomiles, as well as theologians like Marcion and Valentinus, believed that the devil was involved in creating the world. Today these views are not part of mainstream Christianity.

The Foundations of Arithmetic
The Foundations of Arithmetic (German: Die Grundlagen der Arithmetik) is a book by Gottlob Frege, published in 1884, which investigates the philosophical foundations of arithmetic. Frege refutes other theories of number and develops his own theory of numbers. The Grundlagen also helped to motivate Frege's later works in logicism. The book was not well received and was not read widely when it was published. It did, however, draw the attentions of Bertrand Russell and Ludwig Wittgenstein, who were both heavily influenced by Frege's philosophy. An English translation was published (Oxford, 1950) by J. L. Austin, with a second edition in 1960.

Aarne–Thompson Classification Systems
The Aarne–Thompson classification systems are indices used to classify folktales: the Aarne–Thompson Motif-Index (catalogued by alphabetical letters followed by numerals), the Aarne–Thompson Tale Type Index (cataloged by AT or AaTh numbers), and the Aarne–Thompson–Uther classification system (developed in 2004 and cataloged by ATU numbers). They are named after their authors, Antti Aarne, Stith Thompson, and Hans-Jörg Uther. The indices are used in folkloristics to organize, classify, and analyze folklore narratives and are essential tools for folklorists, as Alan Dundes explained in 1997 about the first two indices, "the identification of folk narratives through motif and/or tale type numbers has become an international sine qua non among bona fide folklorists".

1888–1893 Uprisings of Hazaras
The 1888–1893 Uprisings of Hazaras occurred in the aftermath of the Second Anglo-Afghan War, when the Afghan Emirate signed the Treaty of Gandamak. Afghan King Abdur Rahman Khan set out to bring the Turkistan, Hazarajat and Kafiristan regions under his control. He launched several campaigns in the Hazarajat due to resistance from the Hazaras, and he conducted a widespread campaign on its population. Over sixty percent of the total Hazara population was killed with some being displaced by fleeing to Quetta and other adjoining areas. The Hazara land was distributed among loyalist villagers of nearby non-Hazaras. Moreover, many Hazaras were sold in the markets of Kabul and Qandahar. Abdur Rahman arrested Syed Jafar, chief of the Sheikh Ali Hazara tribe, and jailed him in Mazar-e-Sharif. The repression after the uprising has been called the most significant case of genocide or ethnic cleansing in the history of modern Afghanistan.

The Liexian Zhuan, sometimes translated as Biographies of Immortals, is the oldest extant Chinese hagiography of Daoist xian "transcendents; immortals; saints; alchemists". The text, which compiles the life stories of about 70 mythological and historical xian, was traditionally attributed to the Western Han dynasty editor and imperial librarian Liu Xiang (77-8 BCE), but internal evidence dates it to the 2nd century CE during the Eastern Han period. The Liexian Zhuan became a model for later authors, such as Ge Hong's 4th century CE Shenxian zhuan ("Biographies of Divine Immortals").

First Generation of Intellectual Movements in Iran
First Generation of Intellectual movements in Iran (Persian: نسل اول جنبش های روشنفکری در ایران, romanized: Nasl-e Aval-e Jonbesh Hay-e Roshan Fekri dar Iran) or Iranian Enlightenment (Persian: روشنگری ایرانی, romanized: Roshangari-e Irani) was a period in the mid-19th- to early-20th- century in Iran, which was accompanied by new ideas in the traditional Iranian society. During the rule of the Qajar dynasty, and especially after the defeat of Iran, in the war with the Russian Empire, due to cultural exchanges, new ideas were formed among the educated class of Iran. This military defeat also encouraged the Qajar commanders to overcome the backwardness. The establishment of Dar ul-Fonun, the first modern university in Iran and the arrival of foreign professors, caused the thoughts of European thinkers to enter Iran, followed by the first signs of enlightenment and intellectual movements in Iran. During this period, intellectual groups were formed in Secret societies and secret associations. Among these Secret societies, we can mention Mirza Malkam Khan's "Faramosh Khaneh" (based on Masonic lodges), Anjoman-e Bagh-e Meykadeh, Society of Humanity and Mokhadarat Vatan Association. These groups spread their ideas by distributing leaflets and newspapers. These secret societies stressed the need to reform the land and administrative system and reduce the role of the clergy in society, as well as to limit the rulers within the framework of the law. Iranian thinkers based their work on confronting religious traditions, they were confronted with Shia Islam, which on the one hand was mixed with superstitions, and on the other hand, the strictness and intellectual prejudice of some religious people caused intellectual-scientific decline. Among the thinkers of this period were Mirza Malkam Khan, Mirza Abdul'Rahim Talibov, Mirza Fatali Akhundov, Iraj Mirza, Mirzadeh Eshghi, Aref Qazvini, Mirza Hassan Roshdieh, Mirza Aqa Khan Kermani, Hassan Taqizadeh, Amir Kabir and Haydar Khan Amo-oghli. Most of these intellectuals expressed their thoughts through poetry and fiction, simple stories and parables that were easier for people to understand helped to spread Enlightenment throughout Iran. The first generation of intellectuals in Iran went beyond the borders of this country and influenced neighboring countries such as Afghanistan and the Arab world such as Egypt. People like Jamāl al-Dīn al-Afghānī collaborated with most of the great thinkers of this period from Iran.
