Religion chapter
QMRThe philosophical question of whether morality is absolute, relative, or illusory leads to questions about the nature of evil, with views falling into one of four opposed camps: moral absolutism, amoralism, moral relativism, and moral universalism.
QMRThe International Association of Fire Fighters (IAFF) is a labor union. It's logo is a cross
QMRThe Grapevine Cross (Georgian: ჯვარი ვაზისა, Jvari Vazisa) also known as the Georgian cross or Saint Nino's cross, is a major symbol of the Georgian Orthodox Church and dates from the 4th century AD, when Christianity became the official religion in the kingdom of Iberia (Kartli).
It is recognisable by the slight drooping of its horizontal arms. Traditional accounts credit Saint Nino, a Cappadocian woman who preached Christianity in Iberia (corresponding to modern eastern Georgia) early in the 4th century, with this unusual shape of cross. The legend has it that she received the grapevine cross from the Virgin Mary (or, alternatively, she created it herself on the way to Mtskheta) and secured it by entwining with her own hair. Nino came with this cross on her mission to Georgia. However, the familiar representation of the cross, with its peculiar drooping arms, did not appear until the early modern era.
According to traditional accounts, the cross of St Nino was kept at Svetitskhoveli Cathedral in Mtskheta until 541. During the Persian invasions it was taken to Armenia and stayed there until David IV of Georgia recovered the Armenian city of Ani from the Muslims in 1124, and brought the cross to Mtskheta. King Vakhtang III of Georgia (1303-1307) enshrined the cross in a special envelope, decorated with the scenes from St. Nino's life. During the 1720s, when Georgia was subjected to a Persian and Ottoman invasions, the cross was taken to safer areas, to Ananuri in highland Georgia. From there, the Georgian bishop Timothy brought the cross to the emigre Georgian prince Bakar, residing in Moscow and then in Lyskovo. The Georgian king Erekle II tried to recover the relic for Georgia from Bakar's family, to no avail. In 1801, Bakar's grandson George presented the cross to the Russian tsar Alexander I who returned it to Georgia in 1802 on the occasion of Georgia's incorporation within the Russian Empire. Since then, the cross has been preserved in the Sioni Cathedral in Tbilisi, Georgia.[1]

QMRIn woodworking[edit]

A cross dowel is a cylindrically shaped metal nut (i.e., a metal dowel) that is used to join two pieces of wood. Like other metal nuts, it has an inside threaded hole, although the hole is unusual in that it passes through the sides of the dowel. One or both ends of the dowel are slotted, with the slots oriented parallel to the threaded hole through which the bolt will pass.
In a cross dowel application, the two pieces of wood are aligned and a bolt hole is drilled through one piece of wood and into the other. A dowel hole is drilled laterally across the bolt hole and the cross dowel is inserted into it. A screwdriver is inserted into the slot at the end of the cross dowel and the dowel is rotated so that its threaded hole aligns with the bolt hole. The bolt is then inserted into the bolt hole and screwed into the cross dowel until the wood pieces are held tightly together.
QMRFasting periods[edit]

The time and type of fast is generally uniform for all Orthodox Christians; the times of fasting are part of the ecclesiastical calendar, and the method of fasting is set by the Holy Canons and Sacred Tradition. There are four major fasting periods during the year:
The Nativity Fast (Advent or "Winter Lent") which is the 40 days preceding the Nativity of Christ (Christmas), beginning on 15 November and running through 24 December. This fast becomes more severe beginning 12 December, and Christmas Eve is observed as a strict fast day.
Great Lent which consists of the 6 weeks (40 Days) preceding Palm Sunday, and Great Week (Holy Week) which precedes Pascha (Easter).
The Apostles' Fast which varies in length from 8 days to 6 weeks. It begins on the Monday following All Saints Sunday (the first Sunday after Pentecost) and extends to the Feast of Saints Peter and Paul on 29 June. Since the date of Pentecost depends on that of Pascha, and Pascha is determined on the lunar calendar, this fast can disappear completely under New Calendar observance (This is one of the objections raised by opponents to the New Calendar).
The Dormition Fast, a two-week-long Fast preceding the Dormition of the Theotokos (repose of The Virgin Mary), lasting from 1 August through 15 August.
In addition to these fasting seasons, Orthodox Christians fast on every Wednesday (in commemoration of Christ's betrayal by Judas Iscariot), and Friday (in commemoration of Christ's Crucifixion) throughout the year. Monastics often fast on Mondays (in imitation of the Angels, who are commemorated on that day in the weekly cycle, since monastics are striving to lead an angelic life on earth, and angels neither eat nor drink).
Orthodox Christians who are preparing to receive the Eucharist do not eat or drink at all from vespers (sunset) until after taking Holy Communion. A similar total fast is expected to be kept on the Eve of Nativity, the Eve of Theophany (Epiphany), Great Friday and Holy Saturday for those who can do so. There are other individual days observed as fasts (though not as days of total fasting) no matter what day of the week they fall on, such as the Beheading of St. John the Baptist on 29 August and the Exaltation of the Holy Cross on 14 September.
Strict fasting is canonically forbidden on Saturdays and Sundays due to the festal character of the Sabbath and the Resurrection, respectively. On those days wine and oil are permitted even if abstention from them would be otherwise called for. Holy Saturday is the only Saturday of the year where a strict fast is kept every year, though it is also kept on the Eve of Theophany in years when that day falls on Saturday.
There are also four periods in the liturgical year during which no fasting is permitted, even on Wednesday and Friday. These fast-free periods are:
The week following Pascha (Easter), also known as Bright Week.
The week following Pentecost.
The period from the Nativity of Christ up to (but not including) the Eve of Theophany (Epiphany). The day of Theophany itself is always fast-free, even if it falls on a Wednesday or Friday.
The week following the Sunday of the Publican and the Pharisee (one of the preparatory Sundays before Great Lent). This is fast-free to remind the faithful not to boast like the Pharisee that he fasts for two days out of the week Luke 18:12.
When certain feast days fall on fast days, the fasting laws are lessened to a certain extent, to allow some consolation in the trapeza (refectory) for the longer services, and to provide an element of sober celebration to accompany the spiritual joy of the feast.
It is considered a greater sin to advertise one's fasting than not to participate in the fast. Fasting is a purely personal communication between the Orthodox Christian and God. If one has health concerns, or responsibilities that cannot be fulfilled because of fasting, then it is perfectly permissible not to fast. An individual's observance of the fasting laws is not to be judged by the community (Romans 14:1–4), but is a private matter between him and his Spiritual Father or Confessor.
QMRThe number 7 is a recurring numerical theme in the Hebrew scriptures. The menorah has seven lamps on four branches. The menorah is seen as one of the most holy symbols for the Jews. It is no coincidence it has four branches.
1025–1450[edit]

The period when a distinctive Islamic system of astronomy flourished. The period began as the Muslim astronomers began questioning the framework of the Ptolemaic system of astronomy. These criticisms, however, remained within the geocentric framework and followed Ptolemy's astronomical paradigm; one historian described their work as "a reformist project intended to consolidate Ptolemaic astronomy by bringing it into line with its own principles."[18]
Between 1025 and 1028, Ibn al-Haytham wrote his Al-Shukuk ala Batlamyus (meaning "Doubts on Ptolemy"). While maintaining the physical reality of the geocentric model, he criticized elements of the Ptolemic models. Many astronomers took up the challenge posed in this work, namely to develop alternate models that resolved these difficulties. In 1070, Abu Ubayd al-Juzjani published the Tarik al-Aflak. In his work, he indicated the so-called "equant" problem of the Ptolemic model. Al-Juzjani even proposed a solution for the problem. In Al-Andalus, the anonymous work al-Istidrak ala Batlamyus (meaning "Recapitulation regarding Ptolemy"), included a list of objections to the Ptolemic astronomy.
Other critical astronomers include: Mu'ayyad al-Din al-'Urdi (c. 1266), Nasir al-Din al-Tusi (1201–74), Qutb al-Din al Shirazi (c. 1311), Sadr al-Sharia al-Bukhari (c. 1347), Ibn al-Shatir (c. 1375), and Ali al-Qushji (c. 1474).[19]
1450–1900[edit]
The period of stagnation, when the traditional system of astronomy continued to be practised with enthusiasm, but with rapidly decreasing innovation of any major significance.
A large corpus of literature from Islamic astronomy remains today, numbering around some 10,000 manuscript volumes scattered throughout the world. Much of this has not even been catalogued. Even so, a reasonably accurate picture of Islamic activity in the field of astronomy can be reconstructed.

Quadratic equations are based on the quadrant.Muḥammad ibn Mūsā al-Khwārizmī[note 1] (Arabic: محمد بن موسى الخوارزمی; c. 780 – c. 850), formerly Latinized as Algoritmi,[note 2] was a Persian[3] mathematician, astronomer and geographer during the Abbasid Caliphate, a scholar in the House of Wisdom in Baghdad.
In the 12th century, Latin translations of his work on the Indian numerals introduced the decimal positional number system to the Western world.[4] Al-Khwārizmī's The Compendious Book on Calculation by Completion and Balancing presented the first systematic solution of linear and quadratic equations in Arabic. In Renaissance Europe, he was considered the original inventor of algebra, although it is now known that his work is based on older Indian or Greek sources.[5] He revised Ptolemy's Geography and wrote on astronomy and astrology.
Some words reflect the importance of al-Khwārizmī's contributions to mathematics. "Algebra" is derived from al-jabr, one of the two operations he used to solve quadratic equations. Algorism and algorithm stem from Algoritmi, the Latin form of his name.[6] His name is also the origin of (Spanish) guarismo[7] and of (Portuguese) algarismo, both meaning digit.
Al-Khwārizmī's contributions to mathematics, geography, astronomy, and cartography established the basis for innovation in algebra and trigonometry. His systematic approach to solving linear and quadratic equations led to algebra, a word derived from the title of his 830 book on the subject, "The Compendious Book on Calculation by Completion and Balancing".
Al-Khwārizmī's method of solving linear and quadratic equations worked by first reducing the equation to one of six standard forms (where b and c are positive integers)
squares equal roots (ax2 = bx)
squares equal number (ax2 = c)
roots equal number (bx = c)
squares and roots equal number (ax2 + bx = c)
squares and number equal roots (ax2 + c = bx)
roots and number equal squares (bx + c = ax2)
QMRThe name and explanations given by Mercator to his world map (Nova et Aucta Orbis Terrae Descriptio ad Usum Navigantium Emendata: "new and augmented description of Earth corrected for the use of sailors") show that it was expressly conceived for the use of marine navigation. Although the method of construction is not explained by the author, Mercator probably used a graphical method, transferring some rhumb lines previously plotted on a globe to a square graticule, and then adjusting the spacing between parallels so that those lines became straight, making the same angle with the meridians as in the globe.
QMRThe Cross of Lorraine (French: Croix de Lorraine) was originally a heraldic cross. The two-barred cross consists of a vertical line crossed by two shorter horizontal bars. In most renditions, the horizontal bars are "graded" with the upper bar being the shorter, though variations with the bars of equal length are also seen. The Lorraine name has come to signify several cross variations, including the patriarchal cross with its bars near the top.

The papal cross is an emblem for the office of the Pope in ecclesiastical heraldry. It is depicted as a staff with three horizontal bars near the top, in diminishing order of length as the top is approached. It is thus analogous to the two-barred archiepiscopal cross used in heraldry to indicate an archbishop, and seems to have been used precisely to indicate an ecclesiastical rank still higher than that of archbishop. In the past, this design of the cross was often used in ecclesiastical heraldry as a distinctive mark of his office. It was often merely an artistic device, as use of a staff or crosier was not part of the traditional papal insignia.[1] However, at least one staff surmounted with a papal cross does exist.
Symbolism connected with the papal powers have been attached to the three crossbars, similar to the symbolism attached to the three bands on the papal tiara.
QMRCard condition is one aspect of trading cards that determine the value of a card. There are four areas of interest in determining a cards condition. Centering, corners, edges and surface are taken into consideration, for imperfections, such as color spots and blurred images, and wear, such as creases, scratches and tears, when determining a trading cards value.[25] Cards are considered poor to pristine based on their condition, or in some cases rated 1 through 10.[26] A card in pristine condition, for example, will generally be valued higher than a card in poor condition.

QMRWhile rupajhanas differ considering their characteristics, arupajhanas differ as their object is determined by the level of the jhana:
fifth jhāna: infinite space,
sixth jhāna: infinite consciousness,
seventh jhāna: infinite nothingness,
eighth jhāna: neither perception nor non-perception.
This has to be understood. In the fourth rupajhana, there is already Upekkha, equanimity and Ekkagata, concentration, but the mind is still focused on a "material" object, as any color.
In the fifth jhana, the meditator discovers that there is no object, but only an infinite space, which is empty. This perception motivates the interest of claiming arupajhanas.
In the sixth jhana, it becomes obvious that space has no existence. There is only infinite consciousness.
In the seventh jhana appears the feeling that there is no consciousness, but nothingness.
The eighth jhana consists in the most discrete possible state of mind, which justifies the using of "neither perception nor non-perception".
These "explanations" do not refer to any intellectual, philosophical comprehension, which disappear since the second jhana. They attempt to figure mental process. The arūpajhānas are part of the kammatthanas, and are referred to as the four "formless states".
QMRClassical Sanskrit[edit]
For nearly 2000 years, Sanskrit was the language of a cultural order that exerted influence across South Asia, Inner Asia, Southeast Asia, and to a certain extent East Asia.[18] A significant form of post-Vedic Sanskrit is found in the Sanskrit of Indian epic poetry—the Ramayana and Mahabharata. The deviations from Pāṇini in the epics are generally considered to be on account of interference from Prakrits, or innovations, and not because they are pre-Paninian.[19] Traditional Sanskrit scholars call such deviations ārṣa (आर्ष), meaning 'of the ṛṣis', the traditional title for the ancient authors. In some contexts, there are also more "prakritisms" (borrowings from common speech) than in Classical Sanskrit proper. Buddhist Hybrid Sanskrit is a literary language heavily influenced by the Middle Indo-Aryan languages, based on early Buddhist Prakrit texts which subsequently assimilated to the Classical Sanskrit standard in varying degrees.[20]
There were four principal dialects of classical Sanskrit: paścimottarī (Northwestern, also called Northern or Western), madhyadeśī (lit., middle country), pūrvi (Eastern) and dakṣiṇī (Southern, arose in the Classical period). The predecessors of the first three dialects are attested in Vedic Brāhmaṇas, of which the first one was regarded as the purest (Kauṣītaki Brāhmaṇa, 7.6).[21]

QMRIn economics, factors of production, resources, or inputs are what is used in the production process to produce output—that is, finished goods and services. The amounts of the various inputs used determine the quantity of output according to a relationship called the production function. There are three basic resources or factors of production: land, labour, and capital. These factors are also frequently labeled "producer goods" to distinguish them from the goods or services purchased by consumers, which are frequently labeled "consumer goods." All three of these are required in combination at a time to produce a commodity.
Factors of production may also refer specifically to the primary factors, which are land, labor (the ability to work), and capital goods applied to production. Materials and energy are considered secondary factors in classical economics because they are obtained from land, labour and capital. The primary factors facilitate production but neither become part of the product (as with raw materials) nor become significantly transformed by the production process (as with fuel used to power machinery). Land includes not only the site of production but natural resources above or below the soil. Recent usage has distinguished human capital (the stock of knowledge in the labor force) from labor.[1] Entrepreneurship is also sometimes considered a factor of production.[2] Sometimes the overall state of technology is described as a factor of production.[3] The number and definition of factors varies, depending on theoretical purpose,[4] empirical emphasis, or school of economics.[5]
A fourth factor?[edit]
As mentioned, recent authors have added to the classical list. For example, J.B. Clark saw the co-ordinating function in production and distribution as being served by entrepreneurs; Frank Knight introduced managers who co-ordinate using their own money (financial capital) and the financial capital of others. In contrast, many economists today consider "human capital" (skills and education) as the fourth factor of production, with entrepreneurship as a form of human capital. Yet others refer to intellectual capital. More recently, many have begun to see "social capital" as a factor, as contributing to production of goods and services.
Entrepreneurship[edit]
Consider entrepreneurship as a factor of production, leaving debate aside. In markets, entrepreneurs combine the other factors of production, land, labor, and capital, to make a profit. Often these entrepreneurs are seen as innovators, developing new ways to produce and new products. In a planned economy, central planners decide how land, labor, and capital should be used to provide for maximum benefit for all citizens. Of course, just as with market entrepreneurs, the benefits may mostly accrue to the entrepreneurs themselves.
The word has been blown apart by the government. The sociologist C. Wright Mills refers to "new entrepreneurs" who work within and between corporate and government bureaucracies in new and different ways.[10] Others (such as those practicing public choice theory) refer to "political entrepreneurs," i.e., politicians and other actors.
Much controversy rages about the benefits produced by entrepreneurship. But the real issue is about how well institutions they operate in (markets, planning, bureaucracies, government) serve the public. This concerns such issues as the relative importance of market failure and government failure.
In the book Accounting of ideas, "intequity", a neologism, is abstracted from equity to add a newly researched production factor of the capitalist system. Equity, which is regarded part of capital was divided into equity and intequity. Entrepreneurship was divided into network related matters and creating related matters. Network related matters function in the sphere of equity and creating related matters in spheres of intequities.[11]
Natural resources[edit]
Ayres and Warr (2010) are among the economists who criticize orthodox economics for overlooking the role of natural resources and the effects of declining resource capital.[9] See also: Natural resource economics
Energy[edit]
Exercise can be seen as individual factor of production, with an elastication larger than labor.[12] A cointegration analysis support results derived from linear exponentional (LINEX) production functions.[13. The fourth is always different.
The cross in square plan takes the form of the Quincunx
A tetraconch, from the Greek for "four shells", is a building, usually a church or other religious building, with four apses, one in each direction, usually of equal size. The basic ground plan of the building is therefore a Greek cross. They are most common in Byzantine, and related schools such as Armenian and Georgian architecture. It has been argued that they were developed in these areas or Syria, and the issue is a matter of contention between the two nations in the Caucasus.[1] Apart from churches, the form is suitable for a mausoleum or baptistery. Normally there will be a higher central dome over the central space.
The Basilica of San Lorenzo, Milan (370) is possibly the first example of a grander type, the "aisled tetraconch", with an outer ambulatory. In middle Byzantine architecture, the cross-in-square plan was developed, essentially filling out the tetraconch to form a square-ish exterior. Either of these types may also be described less precisely as "cross-domed". In these types the semi-dome of the apse usually starts directly from the central domed space.
The plan of Zvartnots Cathedral, Armenia.
The ruined Ninotsminda Cathedral of c.575 in Georgia is perhaps the oldest example in that country. The Armenian and Georgian examples are later than some others but a distinctive and sophisticated form of the plan. They are similar to the cross-in-square plan, but in Georgia the corner spaces, or "angle chambers", are only accessible from the central space through narrow openings, and are closed off from the apses (as at Jvari monastery, see plan above). In Armenia, the plan also developed in the 6th century, where the plan of St. Hripsime Church, Echmiadzin (618) is almost identical to Jvari.[2] Later a different plan was developed, with a tetraconch main space completely encircled by an aisle, or ambulatory in the terminology used for Western churches,[3] as at the ruined mid-7th century Zvartnots Cathedral.[4] The ruined so-called Cathedral of Bosra, of the early 6th century, is the earliest major Syrian tetraconch church,[5] though in Syria the type did not remain as popular as in the Caucasus.
The Mausoleum of Galla Placidia in Ravenna (425–30), world-famous for its mosaics, is almost a tetraconch, although there are short vaulted arms leading from the central space to each apse-end. These end in a flat wall with no semi-dome, and the entrance end is slightly longer.
Bramante's plan for St Peter's 1503–06
A famous revival of the tetraconch formula in the West is Bramante's first design for the Basilica of St. Peter, Rome.
A triconch building has only three apses; normally omitting the one at the liturgical west end, which may be replaced with a narthex. Many churches of both types have been extended, especially to the west by addition of naves, so that they came to resemble more conventional basilica-type churches. The church in Istanbul of St. Mary of the Mongols is an example.
QMRJvari Monastery (Georgian: ჯვრის მონასტერი) is a sixth century Georgian Orthodox monastery near Mtskheta, eastern Georgia. Along with other historic structures of Mtskheta, it is listed as a World Heritage site by UNESCO.
