Alaska Native Claims Settlement Act

The Alaska Native Claims Settlement Act (ANCSA) was signed into law by President Richard Nixon on December 18, 1971, constituting at the time the largest land claims settlement in United States history. ANCSA was intended to resolve long-standing issues surrounding aboriginal land claims in Alaska, as well as to stimulate economic development throughout Alaska. The settlement established Alaska Native claims to the land by transferring titles to twelve Alaska Native regional corporations and over 200 local village corporations. A thirteenth regional corporation was later created for Alaska Natives who no longer resided in Alaska. The act is codified as 43 U.S.C. 1601 et seq. Background When Alaska became a state in 1959, section 4 of the Alaska Statehood Act provided that any existing Alaska Native land claims would be unaffected by statehood and held in status quo. Yet while section 4 of the act preserved Native land claims until later settlement, section 6 allowed for the state government to claim lands deemed vacant. Section 6 granted the state of Alaska the right to select lands then in the hands of the federal government, with the exception of Native territory. As a result, nearly from the public domain would eventually be transferred to the state. The state government also attempted to acquire lands under section 6 of the Statehood Act that were subject to Native claims under section 4, and that were currently occupied and used by Alaska Natives. The federal Bureau of Land Management began to process the Alaska government's selections without taking into account the Native claims and without informing the affected Native groups. It was against this backdrop that the original language for a land claims settlement was developed. A 9.2-magnitude earthquake struck the state in 1964. Recovery efforts drew the attention of the federal government The Federal Field Committee for Development Planning in Alaska decided that Natives should receive $100 million and 10% of revenue as a royalty. Nothing was done with this proposal, however, and a freeze on land transfers remained in effect. In 1966, Emil Notti called for a statewide meeting inviting numerous leaders around Alaska to gather and create the first meeting of a committee. The historic meeting was held October 18, 1966 - on the 99th anniversary of the transfer of Alaska from Russia. Notti presided over the three-day conference as it discussed matters of land recommendations, claims committee's, and political challenges the act would have getting through congress. Many respected politicians and businessmen attended the meeting and delegates were astonished at the attention which they received from well-known political figures of the state. The growing presence and political importance of Natives was evidenced when association leaders were elected to the legislature. Members of the associated gathered and were able to gain seven of the sixty seats in the legislature. When the group met a second time early in 1967, it emerged with a new name, The Alaska Federation of Natives, and a new full-time President, Emil Notti. AFN changed the human rights and economic stability of the Alaska Native population forever. In 1968, Governor Walter Hickel summoned a group of Native leaders to work out a settlement that would be satisfactory to Natives. The group met for ten days and asked for $20 million in exchange for requested lands. They also asked for 10% of federal mineral lease revenue. In 1969, President Nixon appointed Hickel as Secretary of the Interior. The Alaska Federation of Natives (AFN) protested against Hickel's nomination, but he was eventually confirmed. Hickel worked with the AFN, negotiating with Native leaders and state government over the disputed lands. Offers went back and forth, with each rejecting the other's proposals. The AFN wanted rights to land, while then-Governor Keith Miller believed Natives did not have legitimate claims to state land in light of the provisions of the Alaska Statehood Act. But a succeeding Alaska state administration under Governor William A. Egan would stake out positions upon which the AFN and other stakeholders could largely agree. Native leaders, in addition to Alaska's congressional delegation and the state's newly elected Governor William A. Egan, eventually reached the basis for presenting an agreement to Congress. The proposed settlement terms faced challenges in both houses but found a strong ally in Senator Henry M. Jackson from Washington state. The most controversial issues that continued to hold up approval were methods for determining land selection by Alaska Natives and financial distribution. In 1968, the Atlantic-Richfield Company discovered oil at Prudhoe Bay on the Arctic coast, catapulting the issue of land ownership into headlines. In order to lessen the difficulty of drilling at such a remote location and transporting the oil to the lower 48 states, the oil companies proposed building a pipeline to carry the oil across Alaska to the port of Valdez At Valdez, the oil would be loaded onto tankers and shipped to the contiguous states. The plan had been approved, but a permit to construct the pipeline, which would cross lands involved in the land claims dispute, could not be granted until the Native claims were settled. With major petroleum dollars on the line, pressure mounted to achieve a definitive legislative resolution at the federal level. In 1971, the Alaska Native Claims Settlement Act was signed into law by President Nixon. It abrogated Native claims to aboriginal lands except those that are the subject of the law. In return, Natives retained up to of land and were paid $963 million. The land and money were to be divided among regional, urban, and village tribal corporations established under the law, often recognizing existing leadership. Effect of land conveyances In 1971, barely one million acres of land in Alaska were in private hands. ANCSA, together with section 6 of Alaska Statehood Act, which the new act allowed to come to fruition, affected ownership to about of land in Alaska once wholly controlled by the federal government. That is larger by than the combined areas of Maine, Vermont, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland and Virginia. When the bill passed in 1971, it included provisions that had never before been attempted in previous United States settlements with Native Americans. The newly passed Alaska Native Claims Settlement Act created twelve Native regional economic development corporations. Each corporation was associated with a specific region of Alaska and the Natives who had traditionally lived there. This innovative approach to native settlements engaged the tribes in corporate capitalism. The idea originated with the AFN, who believed that the Natives would have to become a part of the capitalist system in order to survive. As stockholders in these corporations, the Natives could earn some income and stay in their traditional villages. If the corporations were managed properly, they could make profits that would enable individuals to stay, rather than having to leave Native villages to find better work. This was intended to help preserve Native culture. Native and state land selection Alaska Natives had three years from passage of ANCSA to make land selections of the granted under the act. In some cases Native corporations received outside aid in surveying the land. For instance, Doyon, Limited (one of the 13 regional corporations) was helped by the Geophysical Institute of the University of Alaska. The Institute determined which land contained resources such as minerals and coal. NASA similarly provided satellite imagery to aid in Native corporations finding areas most suited for vegetation and their traditional subsistence culture. The imagery showed locations of caribou and moose, as well as forests with marketable timber. In total about were analyzed for Doyon. Natives were able to choose tens of thousands of acres of land rich with timber while Doyon used mineral analysis to attract businesses. The state of Alaska to date has been granted approximately 85% or of the land claims it has made under ANCSA. The state is entitled to a total of under the terms of the Statehood Act. Originally the state had 25 years after passage of the Alaska Statehood Act to file claims under section 6 of the act with the Bureau of Land Management (BLM). Amendments to ANCSA extended that deadline until 1994, with the expectation that BLM would complete processing of land transfers subject to overlapping Native claims by 2009. Nonetheless, some Native and state selections under ANCSA remained unresolved as late as December 2014. Criticism of ANCSA There was largely positive reaction to ANCSA, although not entirely. The act was supported by Natives as well as non-Natives, and likewise enjoyed bipartisan support. Natives were heavily involved in the legislative process, and the final draft of the act used many AFN ideas. Some Natives have argued that ANCSA has hastened cultural genocide of Alaska Natives. Some Natives critiqued ANCSA as an illegitimate treaty since only tribal leaders were involved and the provisions of the act were not voted on by indigenous populations. One native described it as a social and political experiment. Critics have also argued that Natives so feared massacre or incarceration that they offered no resistance to the act. Others have argued that the settlement was arguably the most generous afforded by the United States to a Native group. They note that some of the largest and most profitable corporations in the state are the twelve created by ANCSA. Other critics attacked the act as "Native welfare" and such complaints continue to be expressed. The corporation system has been critiqued, as in some cases stockholders have sold land to outside corporations that have leveled forests and extracted minerals. But supporters of the system argue that it has provided economic benefits for indigenous peoples that outweigh these problems. Selected provisions of ANCSA Native claims in Alaska were extinguished by means of section 4 of ANCSA. In exchange for abrogating Native claims, approximately one-ninth of the state's land plus $962.5 million were distributed to more than 200 local Alaska Native "village corporations" established under section 8, in addition to 12 land-owning for-profit Alaska Native "regional corporations" and a non-land-owning thirteenth corporation for Alaska Natives who had left the state established under section 6. Of the compensation monies, $462.5 million was to come from the federal treasury and the rest from oil revenue-sharing. Settlement benefits would accrue to those with at least one-fourth Native ancestry under sections 3(b) and 5(a). Of the approximately 80,000 Natives enrolled under ANCSA, those living in villages (approximately two-thirds of the total) would receive 100 shares in both a village and a regional corporation. The remaining one-third would be "at large" shareholders with 100 shares in a regional corporation with additional rights to revenue from regional mineral and timber resources. The Alaska Native Allotment Act was revoked but with the proviso that pending claims under that act would continue to be processed under section 18. Successful applicants would be excluded under ANCSA by section 14(h)(5) from land to be used for a primary residence. The twelve regional corporations within the state would administer the settlement. A thirteenth corporation composed of Natives who had left the state would receive compensation but not land. Surface rights to were patented to the Native village and regional corporations under sections 12(c), as well as 14(h)(1) and (8). The surface rights to the patented land were granted to the village corporations and the subsurface right to the land were granted to the regional corporation, creating a split estate pursuant to section 14(f). Alaska Native regional corporations The following thirteen regional corporations were created under ANCSA: Ahtna, Incorporated The Aleut Corporation Arctic Slope Regional Corporation Bering Straits Native Corporation Bristol Bay Native Corporation Calista Corporation Chugach Alaska Corporation Cook Inlet Region, Inc. Doyon, Limited Koniag, Incorporated NANA Regional Corporation Sealaska Corporation The 13th Regional Corporation Additionally, most regions and some villages have created their own nonprofits providing social services and health care through grant funding and federal compacts. The objectives of these nonprofits are varied, but focus generally on cultural and educational activities. These include scholarships for Native students, sponsorship of cultural and artistic events, preservation efforts for Native languages, and protection of sites with historic or religious importance. Alaska Native village and urban corporations ANCSA created about 224 village and urban corporations. Below is a representative list of village and urban corporations created under ANCSA: Ukpeaġvik Iñupiat Corporation, village corporation for Utqiaġvik Bethel Native Corporation, village corporation for Bethel Cape Fox Corporation, village corporation for Saxman Deloycheet, Inc., village corporation for Holy Cross Huna Totem Corporation, village corporation for Hoonah Haida Corporation, village corporation for Hydaburg Goldbelt, Inc., urban corporation for Juneau Paug-Vik, Inc.

https://en.wikipedia.org/wiki/Adoptionism

Adoptionism

Adoptionism, also called dynamic monarchianism, is an early Christian nontrinitarian theological doctrine, which holds that Jesus was adopted as the Son of God at his baptism, his resurrection, or his ascension. Definition Adoptionism is one of two main forms of monarchianism (the other is modalism which considers God to be one while working through the different "modes" or "manifestations" of God the Father, God the Son, and God the Holy Spirit, without limiting his modes or manifestations). Adoptionism denies the eternal pre-existence of Christ, and although it explicitly affirms his deity subsequent to events in his life, many classical trinitarians claim that the doctrine implicitly denies it by denying the constant hypostatic union of the eternal Logos to the human nature of Jesus. Under adoptionism Jesus is currently divine and has been since his adoption, although he is not equal to the Father, per "my Father is greater than I" and as such is a kind of subordinationism. Adoptionism is sometimes, but not always, related to denial of the virgin birth of Jesus. History Early Christianity Adoptionism and High Christology Bart Ehrman holds that the New Testament writings contain two different Christologies, namely a "low" or adoptionist Christology, and a "high" or "incarnation Christology." The "low Christology" or "adoptionist Christology" is the belief "that God exalted Jesus to be his Son by raising him from the dead," thereby raising him to "divine status." The other early Christology is "high Christology," which is "the view that Jesus was a pre-existent divine being who became a human, did the Father’s will on earth, and then was taken back up into heaven whence he had originally come," and from where he appeared on earth. The chronology of the development of these early Christologies is a matter of debate within contemporary scholarship. According to the "evolutionary model" c.q. "evolutionary theories," as proposed by Bousset, followed by Brown, the Christological understanding of Christ developed over time, from a low Christology to a high Christology, as witnessed in the Gospels. According to the evolutionary model, the earliest Christians believed that Jesus was a human who was exalted, c.q. adopted as God's Son, when he was resurrected, signaling the nearness of the Kingdom of God, when all dead would be resurrected and the righteous exalted. Adoptionist concepts can be found in the Gospel of Mark. As Daniel Johansson notes, a majority consensus holds Mark's Jesus as "an exalted, but merely human figure", especially when read in the apparent context of Jewish beliefs. Later beliefs shifted the exaltation to his baptism, birth, and subsequently to the idea of his eternal existence, as witnessed in the Gospel of John. Mark shifted the moment of when Jesus became the son to the baptism of Jesus, and later still Matthew and Luke shifted it to the moment of the divine conception, and finally John declared that Jesus had been with God from the beginning: "In the beginning was the Word". Since the 1970s, the late datings for the development of a "high Christology" have been contested, and a majority of scholars argue that this "High Christology" existed already before the writings of Paul. This "incarnation Christology" or "high Christology" did not evolve over a longer time, but was a "big bang" of ideas which were already present at the start of Christianity, and took further shape in the first few decades of the church, as witnessed in the writings of Paul. According to Ehrman, these two Christologies existed alongside each other, calling the "low Christology" an "adoptionist Christology, and "the "high Christology" an "incarnation Christology." New Testamental epistles Adoptionist theology may also be reflected in canonical epistles, the earliest of which pre-date the writing of the gospels. The letters of Paul the Apostle, for example, do not mention a virgin birth of Christ. Paul describes Jesus as "born of a woman, born under the law" and "as to his human nature was a descendant of David" in the Epistle to the Galatians and the Epistle to the Romans. Many interpreters, however, take his statements in Philippians 2 to imply that Paul believed Jesus to have existed as equal to God before his incarnation. The Book of Hebrews, a contemporary sermon by an unknown author, describes God as saying "You are my son; today I have begotten you." Shepherd of Hermas The 2nd-century work Shepherd of Hermas may also have taught that Jesus was a virtuous man filled with the Holy Spirit and adopted as the Son. While the Shepherd of Hermas was popular and sometimes bound with the canonical scriptures, it didn't retain canonical status, if it ever had it. Theodotus of Byzantium Theodotus of Byzantium (fl. late 2nd century), a Valentinian Gnostic, was the most prominent exponent of adoptionism. According to Hippolytus of Rome (Philosophumena, VII, xxiii) Theodotus taught that Jesus was a man born of a virgin, according to the Council of Jerusalem, that he lived like other men, and was most pious. At his baptism in the Jordan the "Christ" came down upon the man Jesus, in the likeness of a dove (Philosophumena, VII, xxiii), but Jesus was not himself God until after his resurrection. Adoptionism was declared heresy at the end of the 3rd century and was rejected by the Synods of Antioch and the First Council of Nicaea, which defined the orthodox doctrine of the Trinity and identified the man Jesus with the eternally begotten Son or Word of God in the Nicene Creed. The belief was also declared heretical by Pope Victor I. Ebionites Adoptionism was also adhered to by the Jewish Christians known as Ebionites, who, according to Epiphanius in the 4th century, believed that Jesus was chosen on account of his sinless devotion to the will of God. The Ebionites were a Jewish Christian movement that existed during the early centuries of the Christian Era. They show strong similarities with the earliest form of Jewish Christianity, and their specific theology may have been a "reaction to the law-free Gentile mission." They regarded Jesus as the Messiah while rejecting his divinity and his virgin birth, and insisted on the necessity of following Jewish law and rites. They used the Gospel of the Ebionites, one of the Jewish–Christian gospels; the Hebrew Book of Matthew starting at chapter 3; revered James the brother of Jesus (James the Just); and rejected Paul the Apostle as an apostate from the Law. Their name ( Ebionaioi, derived from Hebrew ebyonim, ebionim, meaning "the poor" or "poor ones") suggests that they placed a special value on voluntary poverty. Distinctive features of the Gospel of the Ebionites include the absence of the virgin birth and of the genealogy of Jesus; an Adoptionist Christology, in which Jesus is chosen to be God's Son at the time of his Baptism; the abolition of the Jewish sacrifices by Jesus; and an advocacy of vegetarianism. Spanish Adoptionism Spanish Adoptionism was a theological position which was articulated in Umayyad and Christian-held regions of the Iberian peninsula in the 8th and 9th centuries. The issue seems to have begun with the claim of archbishop Elipandus of Toledo that – in respect to his human nature – Christ was adoptive Son of God. Another leading advocate of this Christology was Felix of Urgel. In Spain, adoptionism was opposed by Beatus of Liebana, and in the Carolingian territories, the Adoptionist position was condemned by Pope Hadrian I, Alcuin of York, Agobard, and officially in Carolingian territory by the Council of Frankfurt (794). Despite the shared name of "adoptionism" the Spanish Adoptionist Christology appears to have differed sharply from the adoptionism of early Christianity. Spanish advocates predicated the term adoptivus of Christ only in respect to his humanity; once the divine Son "emptied himself" of divinity and "took the form of a servant" (Philippians 2:7), Christ's human nature was "adopted" as divine. Historically, many scholars have followed the Adoptionists' Carolingian opponents in labeling Spanish Adoptionism as a minor revival of “Nestorian” Christology. John C. Cavadini has challenged this notion by attempting to take the Spanish Christology in its own Spanish/North African context in his study, The Last Christology of the West: Adoptionism in Spain and Gaul, 785–820. Scholastic Neo-adoptionism A third wave was the revived form ("Neo-adoptionism") of Peter Abelard in the 12th century. Later, various modified and qualified Adoptionist tenets emerged from some theologians in the 14th century. Duns Scotus (1300) and Durandus of Saint-Pourçain (1320) admit the term Filius adoptivus in a qualified sense. In more recent times the Jesuit Gabriel Vásquez, and the Lutheran divines Georgius Calixtus and Johann Ernst Immanuel Walch, have defended adoptionism as essentially orthodox. Modern adoptionist groups A form of adoptionism surfaced in Unitarianism during the 18th century as denial of the virgin birth became increasingly common, led by the views of Joseph Priestley and others. A similar form of adoptionism was expressed in the writings of James Strang, a Latter Day Saint leader who founded the Church of Jesus Christ of Latter Day Saints (Strangite) after the death of Joseph Smith in 1844. In his Book of the Law of the Lord, a purported work of ancient scripture found and translated by Strang, he offers an essay entitled "Note on the Sacrifice of Christ" in which he explains his unique (for Mormonism as a whole) doctrines on the subject. Jesus Christ, said Strang, was the natural-born son of Mary and Joseph, who was chosen from before all time to be the Savior of mankind, but who had to be born as an ordinary mortal of two human parents (rather than being begotten by the Father or the Holy Spirit) to be able to truly fulfill his Messianic role. Strang claimed that the earthly Christ was in essence "adopted" as God's son at birth, and fully revealed as such during the Transfiguration. After proving himself to God by living a perfectly sinless life, he was enabled to provide an acceptable sacrifice for the sins of men, prior to his resurrection and ascension.

https://en.wikipedia.org/wiki/Apollinarism

Apollinarism

Apollinarism or Apollinarianism is a Christological heresy proposed by Apollinaris of Laodicea (died 390) that argues that Jesus had a human body and sensitive human soul, but a divine mind and not a human rational mind, the Divine Logos taking the place of the latter. It was deemed heretical in 381 and virtually died out within the following decades. History The Trinity had been recognized at the Council of Nicea in 325, but debate about exactly what it meant continued. A rival to the more common belief that Jesus Christ had two natures was monophysitism ("one nature"), the doctrine that Christ had only one nature. Apollinarism and Eutychianism were two forms of monophysitism. Apollinaris' rejection that Christ had a human mind was considered an over-reaction to Arianism and its teaching that Christ was a lesser god. Theodoret charged Apollinaris with confounding the persons of the Godhead and with giving in to the heretical ways of Sabellius. Basil of Caesarea accused him of abandoning the literal sense of the scripture, and taking up wholly with the allegorical sense. His views were condemned in a Synod at Alexandria, under Athanasius of Alexandria, in 362, and later subdivided into several different heresies, the main ones of which were the Polemians and the Antidicomarianites. Apollinaris, considering the rational soul and spirit as essentially liable to sin and capable, at its best, of only precarious efforts, saw no way of saving Christ's impeccability and the infinite value of Redemption, except by the elimination of the human spirit from Jesus' humanity, and the substitution of the Divine Logos in its stead. Apollinarism was declared to be a heresy in 381 by the First Council of Constantinople. Christian philosopher William Lane Craig has proposed a neo-Apollinarian Christology in which the divine Logos completes the human nature of Christ. Craig says his proposal is tentative and he welcomes critique and interaction from other scholars. Craig also clarifies his proposed neo-Apollinarian Christology with this statement. "Against Apollinarius, I want to say that Christ did have a complete human nature. He was truly God and truly man. Therefore his death on our behalf as our representative before God was efficacious."

https://en.wikipedia.org/wiki/Acid%E2%80%93base%20reaction

Acid–base reaction

An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH. Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory. Their importance becomes apparent in analyzing acid–base reactions for gaseous or liquid species, or when acid or base character may be somewhat less apparent. The first of these concepts was provided by the French chemist Antoine Lavoisier, around 1776. It is important to think of the acid-base reaction models as theories that complement each other. For example, the current Lewis model has the broadest definition of what an acid and base are, with the Brønsted-Lowry theory being a subset of what acids and bases are, and the Arrhenius theory being the most restrictive. Acid–base definitions Historic development The concept of an acid-base reaction was first proposed in 1754 by Guillaume-François Rouelle, who introduced the word "base" into chemistry to mean a substance which reacts with an acid to give it solid form (as a salt). Bases are mostly bitter in nature. Lavoisier's oxygen theory of acids The first scientific concept of acids and bases was provided by Lavoisier in around 1776. Since Lavoisier's knowledge of strong acids was mainly restricted to oxoacids, such as (nitric acid) and (sulfuric acid), which tend to contain central atoms in high oxidation states surrounded by oxygen, and since he was not aware of the true composition of the hydrohalic acids (HF, HCl, HBr, and HI), he defined acids in terms of their containing oxygen, which in fact he named from Greek words meaning "acid-former" (from the Greek ὀξύς (oxys) meaning "acid" or "sharp" and γεινομαι (geinomai) meaning "engender"). The Lavoisier definition held for over 30 years, until the 1810 article and subsequent lectures by Sir Humphry Davy in which he proved the lack of oxygen in , H2Te, and the hydrohalic acids. However, Davy failed to develop a new theory, concluding that "acidity does not depend upon any particular elementary substance, but upon peculiar arrangement of various substances". One notable modification of oxygen theory was provided by Jöns Jacob Berzelius, who stated that acids are oxides of nonmetals while bases are oxides of metals. Liebig's hydrogen theory of acids In 1838, Justus von Liebig proposed that an acid is a hydrogen-containing compound whose hydrogen can be replaced by a metal. This redefinition was based on his extensive work on the chemical composition of organic acids, finishing the doctrinal shift from oxygen-based acids to hydrogen-based acids started by Davy. Liebig's definition, while completely empirical, remained in use for almost 50 years until the adoption of the Arrhenius definition. Arrhenius definition The first modern definition of acids and bases in molecular terms was devised by Svante Arrhenius. A hydrogen theory of acids, it followed from his 1884 work with Friedrich Wilhelm Ostwald in establishing the presence of ions in aqueous solution and led to Arrhenius receiving the Nobel Prize in Chemistry in 1903. As defined by Arrhenius: an Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H+); that is, an acid increases the concentration of H+ ions in an aqueous solution. This causes the protonation of water, or the creation of the hydronium (H3O+) ion. Thus, in modern times, the symbol H+ is interpreted as a shorthand for H3O+, because it is now known that a bare proton does not exist as a free species in aqueous solution. This is the species which is measured by pH indicators to measure the acidity or basicity of a solution. an Arrhenius base is a substance that dissociates in water to form hydroxide (OH−) ions; that is, a base increases the concentration of OH− ions in an aqueous solution." The Arrhenius definitions of acidity and alkalinity are restricted to aqueous solutions and are not valid for most non-aqueous solutions, and refer to the concentration of the solvent ions. Under this definition, pure H2SO4 and HCl dissolved in toluene are not acidic, and molten NaOH and solutions of calcium amide in liquid ammonia are not alkaline. This led to the development of the Brønsted-Lowry theory and subsequent Lewis theory to account for these non-aqueous exceptions. Overall, to qualify as an Arrhenius acid, upon the introduction to water, the chemical must either cause, directly or otherwise: an increase in the aqueous hydronium concentration, or a decrease in the aqueous hydroxide concentration. Conversely, to qualify as an Arrhenius base, upon the introduction to water, the chemical must either cause, directly or otherwise: a decrease in the aqueous hydronium concentration, or an increase in the aqueous hydroxide concentration. The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water. acid + base → salt + water In this traditional representation an acid–base neutralization reaction is formulated as a double-replacement reaction. For example, the reaction of hydrochloric acid, HCl, with sodium hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some additional water molecules. HCl(aq) + NaOH(aq) → NaCl(aq) + H2O The modifier (aq) in this equation was implied by Arrhenius, rather than included explicitly. It indicates that the substances are dissolved in water. Though all three substances, HCl, NaOH and NaCl are capable of existing as pure compounds, in aqueous solutions they are fully dissociated into the aquated ions H+, Cl−, Na+ and OH−. Brønsted–Lowry definition The Brønsted–Lowry definition, formulated in 1923, independently by Johannes Nicolaus Brønsted in Denmark and Martin Lowry in England, is based upon the idea of protonation of bases through the deprotonation of acids – that is, the ability of acids to "donate" hydrogen ions (H+)—otherwise known as protons—to bases, which "accept" them."Removal and addition of a proton from the nucleus of an atom does not occur – it would require very much more energy than is involved in the dissociation of acids." An acid–base reaction is, thus, the removal of a hydrogen ion from the acid and its addition to the base. The removal of a hydrogen ion from an acid produces its conjugate base, which is the acid with a hydrogen ion removed. The reception of a proton by a base produces its conjugate acid, which is the base with a hydrogen ion added. Unlike the previous definitions, the Brønsted–Lowry definition does not refer to the formation of salt and solvent, but instead to the formation of conjugate acids and conjugate bases, produced by the transfer of a proton from the acid to the base. In this approach, acids and bases are fundamentally different in behavior from salts, which are seen as electrolytes, subject to the theories of Debye, Onsager, and others. An acid and a base react not to produce a salt and a solvent, but to form a new acid and a new base. The concept of neutralization is thus absent. Brønsted–Lowry acid–base behavior is formally independent of any solvent, making it more all-encompassing than the Arrhenius model. The calculation of pH under the Arrhenius model depended on alkalis (bases) dissolving in water (aqueous solution). The Brønsted–Lowry model expanded what could be pH tested using insoluble and soluble solutions (gas, liquid, solid). The general formula for acid–base reactions according to the Brønsted–Lowry definition is: HA + B → BH+ + A− where HA represents the acid, B represents the base, BH+ represents the conjugate acid of B, and A− represents the conjugate base of HA. For example, a Brønsted-Lowry model for the dissociation of hydrochloric acid (HCl) in aqueous solution would be the following: HCl + H2O H3O+ + Cl− The removal of H+ from the HCl produces the chloride ion, Cl−, the conjugate base of the acid. The addition of H+ to the H2O (acting as a base) forms the hydronium ion, H3O+, the conjugate acid of the base. Water is amphoteric—that is, it can act as both an acid and a base. The Brønsted-Lowry model explains this, showing the dissociation of water into low concentrations of hydronium and hydroxide ions: H2O + H2O H3O+ + OH− This equation is demonstrated in the image below: Here, one molecule of water acts as an acid, donating an H+ and forming the conjugate base, OH−, and a second molecule of water acts as a base, accepting the H+ ion and forming the conjugate acid, H3O+. As an example of water acting as an acid, consider an aqueous solution of pyridine, C5H5N. C5H5N + H2O [C5H5NH]+ + OH− In this example, a water molecule is split into a hydrogen ion, which is donated to a pyridine molecule, and a hydroxide ion. In the Brønsted-Lowry model, the solvent does not necessarily have to be water, as is required by the Arrhenius Acid-Base model. For example, consider what happens when acetic acid, CH3COOH, dissolves in liquid ammonia. + + An H+ ion is removed from acetic acid, forming its conjugate base, the acetate ion, CH3COO−. The addition of an H+ ion to an ammonia molecule of the solvent creates its conjugate acid, the ammonium ion, . The Brønsted–Lowry model calls hydrogen-containing substances (like HCl) acids. Thus, some substances, which many chemists considered to be acids, such as SO3 or BCl3, are excluded from this classification due to lack of hydrogen. Gilbert N. Lewis wrote in 1938, "To restrict the group of acids to those substances that contain hydrogen interferes as seriously with the systematic understanding of chemistry as would the restriction of the term oxidizing agent to substances containing oxygen." Furthermore, KOH and KNH2 are not considered Brønsted bases, but rather salts containing the bases OH− and . Lewis definition The hydrogen requirement of Arrhenius and Brønsted–Lowry was removed by the Lewis definition of acid–base reactions, devised by Gilbert N. Lewis in 1923, in the same year as Brønsted–Lowry, but it was not elaborated by him until 1938. Instead of defining acid–base reactions in terms of protons or other bonded substances, the Lewis definition defines a base (referred to as a Lewis base) to be a compound that can donate an electron pair, and an acid (a Lewis acid) to be a compound that can receive this electron pair. For example, boron trifluoride, BF3 is a typical Lewis acid. It can accept a pair of electrons as it has a vacancy in its octet. The fluoride ion has a full octet and can donate a pair of electrons. Thus BF3 + F− → is a typical Lewis acid, Lewis base reaction. All compounds of group 13 elements with a formula AX3 can behave as Lewis acids. Similarly, compounds of group 15 elements with a formula DY3, such as amines, NR3, and phosphines, PR3, can behave as Lewis bases. Adducts between them have the formula X3A←DY3 with a dative covalent bond, shown symbolically as ←, between the atoms A (acceptor) and D (donor). Compounds of group 16 with a formula DX2 may also act as Lewis bases; in this way, a compound like an ether, R2O, or a thioether, R2S, can act as a Lewis base. The Lewis definition is not limited to these examples. For instance, carbon monoxide acts as a Lewis base when it forms an adduct with boron trifluoride, of formula F3B←CO. Adducts involving metal ions are referred to as co-ordination compounds; each ligand donates a pair of electrons to the metal ion. The reaction [Ag(H2O)4]+ + 2NH3 → [Ag(NH3)2]+ + 4H2O can be seen as an acid–base reaction in which a stronger base (ammonia) replaces a weaker one (water) The Lewis and Brønsted–Lowry definitions are consistent with each other since the reaction H+ + OH− H2O is an acid–base reaction in both theories. Solvent system definition One of the limitations of the Arrhenius definition is its reliance on water solutions. Edward Curtis Franklin studied the acid–base reactions in liquid ammonia in 1905 and pointed out the similarities to the water-based Arrhenius theory. Albert F.O. Germann, working with liquid phosgene, , formulated the solvent-based theory in 1925, thereby generalizing the Arrhenius definition to cover aprotic solvents. Germann pointed out that in many solutions, there are ions in equilibrium with the neutral solvent molecules: solvonium ions: a generic name for positive ions. (The term solvonium has replaced the older term lyonium ions: positive ions formed by protonation of solvent molecules.) solvate ions: a generic name for negative ions. (The term solvate has replaced the older term lyate ions: negative ions formed by deprotonation of solvent molecules.) For example, water and ammonia undergo such dissociation into hydronium and hydroxide, and ammonium and amide, respectively: 2 + 2 + Some aprotic systems also undergo such dissociation, such as dinitrogen tetroxide into nitrosonium and nitrate, antimony trichloride into dichloroantimonium and tetrachloroantimonate, and phosgene into chlorocarboxonium and chloride: + 2 + + A solute that causes an increase in the concentration of the solvonium ions and a decrease in the concentration of solvate ions is defined as an acid. A solute that causes an increase in the concentration of the solvate ions and a decrease in the concentration of the solvonium ions is defined as a base. Thus, in liquid ammonia, (supplying ) is a strong base, and (supplying ) is a strong acid. In liquid sulfur dioxide (), thionyl compounds (supplying ) behave as acids, and sulfites (supplying ) behave as bases. The non-aqueous acid–base reactions in liquid ammonia are similar to the reactions in water: + → + → Nitric acid can be a base in liquid sulfuric acid: + 2 → + + 2 The unique strength of this definition shows in describing the reactions in aprotic solvents; for example, in liquid : + → + Because the solvent system definition depends on the solute as well as on the solvent itself, a particular solute can be either an acid or a base depending on the choice of the solvent: is a strong acid in water, a weak acid in acetic acid, and a weak base in fluorosulfonic acid; this characteristic of the theory has been seen as both a strength and a weakness, because some substances (such as and ) have been seen to be acidic or basic on their own right. On the other hand, solvent system theory has been criticized as being too general to be useful. Also, it has been thought that there is something intrinsically acidic about hydrogen compounds, a property not shared by non-hydrogenic solvonium salts. Lux–Flood definition This acid–base theory was a revival of oxygen theory of acids and bases, proposed by German chemist Hermann Lux in 1939, further improved by Håkon Flood circa 1947 and is still used in modern geochemistry and electrochemistry of molten salts. This definition describes an acid as an oxide ion () acceptor and a base as an oxide ion donor. For example: + → + → + → + 2 This theory is also useful in the systematisation of the reactions of noble gas compounds, especially the xenon oxides, fluorides, and oxofluorides. Usanovich definition Mikhail Usanovich developed a general theory that does not restrict acidity to hydrogen-containing compounds, but his approach, published in 1938, was even more general than Lewis theory. Usanovich's theory can be summarized as defining an acid as anything that accepts negative species or donates positive ones, and a base as the reverse. This defined the concept of redox (oxidation-reduction) as a special case of acid–base reactions Some examples of Usanovich acid–base reactions include: + → 2 + (species exchanged: anion) + → 6 + 2 (species exchanged: 3 anions) + → 2 + 2 (species exchanged: 2 electrons) Rationalizing the strength of Lewis acid–base interactions HSAB theory In 1963, Ralph Pearson proposed a qualitative concept known as the Hard and Soft Acids and Bases principle. later made quantitative with help of Robert Parr in 1984. 'Hard' applies to species that are small, have high charge states, and are weakly polarizable. 'Soft' applies to species that are large, have low charge states and are strongly polarizable. Acids and bases interact, and the most stable interactions are hard–hard and soft–soft. This theory has found use in organic and inorganic chemistry. ECW model The ECW model created by Russell S. Drago is a quantitative model that describes and predicts the strength of Lewis acid base interactions, −ΔH. The model assigned E and C parameters to many Lewis acids and bases. Each acid is characterized by an EA and a CA. Each base is likewise characterized by its own EB and CB. The E and C parameters refer, respectively, to the electrostatic and covalent contributions to the strength of the bonds that the acid and base will form. The equation is −ΔH = EAEB + CACB + WThe W term represents a constant energy contribution for acid–base reaction such as the cleavage of a dimeric acid or base. The equation predicts reversal of acids and base strengths. The graphical presentations of the equation show that there is no single order of Lewis base strengths or Lewis acid strengths. Acid–base equilibrium The reaction of a strong acid with a strong base is essentially a quantitative reaction. For example, HCl(aq) + Na(OH)(aq) → H2O + NaCl(aq) In this reaction both the sodium and chloride ions are spectators as the neutralization reaction, H+ + OH− → H2O does not involve them. With weak bases addition of acid is not quantitative because a solution of a weak base is a buffer solution. A solution of a weak acid is also a buffer solution. When a weak acid reacts with a weak base an equilibrium mixture is produced. For example, adenine, written as AH, can react with a hydrogen phosphate ion, . AH + A− + The equilibrium constant for this reaction can be derived from the acid dissociation constants of adenine and of the dihydrogen phosphate ion. [A−] [H+] = Ka1[AH] [] [H+] = Ka2[] The notation [X] signifies "concentration of X". When these two equations are combined by eliminating the hydrogen ion concentration, an expression for the equilibrium constant, K is obtained. [A−] [] = K[AH] []; K'' = Acid–alkali reaction An acid–alkali reaction is a special case of an acid–base reaction, where the base used is also an alkali. When an acid reacts with an alkali salt (a metal hydroxide), the product is a metal salt and water. Acid–alkali reactions are also neutralization reactions. In general, acid–alkali reactions can be simplified to (aq) + (aq) → by omitting spectator ions. Acids are in general pure substances that contain hydrogen cations () or cause them to be produced in solutions. Hydrochloric acid () and sulfuric acid () are common examples. In water, these break apart into ions: → (aq) + (aq) → (aq) + (aq) The alkali breaks apart in water, yielding dissolved hydroxide ions: → (aq) + (aq) See also Acid–base titration Deprotonation Donor number Electron configuration Gutmann–Beckett method Lewis structure Nucleophilic substitution Neutralization (chemistry) Protonation Redox reactions Resonance (chemistry) Notes References Sources External links Acid-base Physiology: an on-line text John W.

Abu al-Faraj al-Isfahani

Ali ibn al-Husayn al-Iṣfahānī (), also known as Abul-Faraj, (full form: Abū al-Faraj ʿAlī ibn al-Ḥusayn ibn Muḥammad ibn Aḥmad ibn al-Ḥaytham al-Umawī al-Iṣfahānī) (284–356AH / 897-967CE) was a litterateur, genealogist, poet, musicologist, scribe, and boon companion in the tenth century. He was of Arab-Quraysh origin and mainly based in Baghdad. He is best known as the author of Kitab al-Aghani ("The Book of Songs"), which includes information about the earliest attested periods of Arabic music (from the seventh to the ninth centuries) and the lives of poets and musicians from the pre-Islamic period to al-Isfahani's time. Given his contribution to the documentation of the history of Arabic music, al-Isfahani is characterised by Sawa as "a true prophet of modern ethnomusicology". Dates The commonly accepted dates of al-Isfahani's birth and death are 284AH/897–8CE and 356/967, based on the dates given by al-Khatib al-Baghdadi which itself bases testimony of al-Isfahani's student, Muhammad ibn Abi al-Fawaris. However, the credibility of these dates is to be treated with discretion. No source places his death earlier than 356/967, but several place it later. These dates are at odds with a reference in the Kitab Adab al-ghuraba ("The Book of the Etiquettes of Strangers"), attributed to al-Isfahani, to his being in the prime of youth (fi ayyam al-shabiba wa-l-siba) in 356/967. Calculation of the approximate dates of his birth and death through the lifespans of his students and his direct informants suggests that he was born before 290/902 and died after 348/960. Biography Abu al-Faraj al-Isfahani was born in Isfahan, Persia (present-day Iran) but spent his youth and made his early studies in Baghdad (present-day Iraq). He was a direct descendant of the last of the Umayyad caliphs, Marwan II, and was thus connected with the Umayyad rulers in al-Andalus, and seems to have kept up a correspondence with them and to have sent them some of his works. He became famous for his knowledge of early Arabian antiquities. His later life was spent in various parts of the Islamic world, in Aleppo with its Hamdanid governor Sayf ad-Dawlah (to whom he dedicated the Book of Songs), in Ray with the Buwayhid vizier Ibn 'Abbad, and elsewhere. Family The epithet, al-Isfahani, refers to the city, Isfahan, on the Iranian plateau. Instead of indicating al-Isfahani's birthplace, this epithet seems to be common to al-Isfahani's family. Every reference al-Isfahani makes to his paternal relatives includes the attributive, al-Isfahani. According to Ibn Hazm (384–456/994–1064), some descendants of the last Umayyad caliph, Marwan b. Muhammad (72–132/691–750), al-Isfahani's forefather, settled in Isfahan. However, it has to be borne in mind that the earliest information we have regarding al-Isfahani's family history only dates to the generation of his great-grandfather, Ahmad b. al-Ḥaytham, who settled in Samarra sometime between 221/835–6 and 232/847. Based on al-Isfahani's references in the Kitab al-Aghani (hereafter, the Aghani), Ahmad b. al-Haytham seems to have led a privileged life in Sāmarrāʾ, while his sons were well-connected with the elite of the Abbasid capital at that time. His son, Abd al-Aziz b. Ahmad, was "one of the high ranking scribes in the days of al-Mutawakkil (r. 232–247/847–861) (min kibār al-kuttāb fī ayyām al-Mutawakkil)". Another son, Muhammad b. Ahmad (viz. al-Isfahani's grandfather), was associated with the Abbasid officials, the vizier Ibn al-Zayyāt (d. 233/847), the scribe Ibrahim b. al-Abbas al-Ṣūlī (176–243/792–857), and the vizier Ubaydallah b. Sulayman (d. 288/901), besides the Ṭālibid notables, above all, al-Husayn b. al-Husayn b. Zayd, who was the leader of the Banu Hashim of his time. The close ties with the Abbasid court continued in the generation of Muhammad's sons, al-Hasan and al-Husayn (al-Isfahani's father). In various places in the Aghani, al-Isfahani refers to Yahya b. Muhammad b. Thawaba (from the Al Thawaba) as his grandfather on his mother's side. It is often suggested that the family of Thawaba, being Shi'i, bequeathed their sectarian inclination to al-Isfahani. However, the identification of the Thawaba family as Shi'is only found in a late source, Yaqut's (574–626/1178–1225) work. Although it is not implausible for the family of Thawaba to have been Shi'i-inclined in one way or another, since many elite families working under the Abbasid caliphate during this period of time indeed allied with Alids or their partisans, there is no evidence that members of the Thawaba family embraced an extreme form of Shi'ism. In short, al-Isfahani came from a family well-entrenched in the networks of the Abbasid elite, which included the officials and the Alids. Despite the epithet, al-Isfahani, it does not seem that the Isfahani family has much to do with the city, Isfahan. Rather, the family was mainly based in Sāmarrāʾ, from the generation of Ahmad b. al-Ḥaytham, and then Baghdad. In the seats of the caliphate, a few members of this family worked as scribes, while maintaining friendship or alliance with other scribes, viziers, and notables. Like many of the court elite, al-Isfahani's family maintained an amicable relationship with the offspring of Ali and allied with families, such as the Thawaba family, sharing their veneration of Ali and Alids. However, it is hard to pinpoint such a reverential attitude towards Alids in terms of sectarian alignment, given the scanty information about al-Isfahani's family and the fluidity of sectarian identities at the time. Education and career The Isfahani family's extensive social outreach is reflected in al-Isfahani's sources. Among the direct informants whom al-Isfahani cites in his works, one finds the members of his own family, who were further connected to other notable families, as mentioned above, the Al Thawaba, the Banū Munajjim, the Yazīdīs, the Ṣūlīs, the Banū Ḥamdūn, the Ṭāhirids, the Banū al-Marzubān, and the Ṭālibids. Given that al-Isfahani and his family very likely settled in Baghdad around the beginning of the tenth century, it is no surprise that he transmitted from a considerable number of the inhabitants of or visitors to that city, such as, to name just a few: Jaḥẓa (d. 324/936), al-Khaffāf, Ali b. Sulaymān al-Akhfash (d. 315/927 or 316/928), and Muhammad b. Jarir al-Ṭabari (d. 310/922). Like other scholars of his time, al-Isfahani travelled in pursuit of knowledge. Although the details are not sufficient for us to establish the dates of his journeys, based on the chains of transmission (asānīd, sing. isnād) al-Isfahani cites consistently and meticulously in every report, it is certain that he transmitted from ʿAbd al-Malik b. Maslama and ʿĀṣim b. Muhammad in Antakya; ʿAbdallāh b. Muhammad b. Ishaq in Ahwaz; and Yahya b. Aḥmad b. al-Jawn in Raqqa. If we accept the ascription of the Kitab Adab al-ghuraba to al-Isfahani, then he once visited Baṣra besides other towns such as Ḥiṣn Mahdī, Mattūth, and Bājistrā. Yet, none of these cities seems to have left as tremendous an impact upon al-Isfahani as Kūfa and Baghdad did. While al-Isfahani's Baghdadi informants were wide-ranging in their expertise as well as sectarian and theological tendencies, his Kūfan sources, to a certain degree, can be characterised as either Shi'i or keen on preserving and disseminating memory that favours Ali and his family. For example, Ibn ʿUqda (d. 333/944), mentioned in both the Aghānī and the Maqātil, is invariably cited for the reports about the Alids and their merits. The journey in search for knowledge taken by al-Isfahani may not be particularly outstanding by the standard of his time, but the diversity of his sources' occupations and fortes is beyond doubt impressive. His informants can be assigned into one or more of the following categories: philologists and grammarians; singers and musicians; booksellers and copyists (sahhafun or warraqun, sing. sahhaf or Warraq); boon companions; tutors (muʾaddibūn, sing. muʾaddib); scribes (kuttāb, sing. kātib); imams or preachers (khuṭabāʾ, sing. khaṭīb); religious scholars (of the ḥadīth, the Qurʾānic recitations and exegeses, or jurisprudence) and judges; poets; and akhbārīs (transmitters of reports of all sorts, including genealogical, historical, and anecdotal reports). The variety of the narrators and their narrations enriched al-Iṣfahānī's literary output, which covers a wide range of topics from amusing tales to the accounts of the Alids' martyrdom. His erudition is best illustrated by Abu Ali al-Muhassin al-Tanukhi's (329–384/941–994) comment: With his encyclopaedic knowledge of music, musicians, poetry, poets, genealogy, history, and other subjects, al-Iṣfahānī established himself as a learned scholar and teacher. He was also a scribe and this is not surprising, given his families’ scribal connections, but the details of his kātib activities are rather opaque. Although both al-Tanūkhī and al-Baghdādī refer to al-Isfahani with the attribute, kātib, they mention nothing of where he worked or for whom. The details of his job as a scribe only come later, with Yaqut, many of whose reports about al-Isfahani prove problematic. For instance, a report from Yaqut claims that al-Isfahani was the scribe of Rukn al-Dawla (d. 366/976) and mentions his resentment at Abū al-Faḍl b. al-ʿAmīd (d. 360/970). However, the very same report is mentioned by Abū Ḥayyān al-Tawḥīdī (active fourth/tenth century) in his Akhlāq al-wazīrayn, where the aforementioned scribe of Rukn al-Dawla is identified as Abū al-Faraj Ḥamd b. Muhammad, not Abū al-Faraj al-Isfahani. Thus, it is hard to know with certainty how and where al-Isfahani was engaged in his capacity as a kātib. Nevertheless, al-Isfahani's association with the vizier, Abū Muḥammad al-Muhallabī (291–352/903–963), is well-documented. The friendship between the two began before al-Muhallabī's vizierate in 339/950. The firm relationship between them is supported by al-Isfahani's poetry collected by al-Thaʿālibī (350–429/961–1038): half of the fourteen poems are panegyrics dedicated to al-Muhallabī. In addition, al-Isfahani's own work, al-Imāʾ al-shawāʿir (“Enslaved Women Who Composed Poetry”), refers to the vizier — presumably, al-Muhallabī — as his dedicatee. His no longer surviving Manājīb al-khiṣyān (“The Noble Eunuchs”), which addresses two castrated male singers owned by al-Muhallabī, was composed for him. His magnum opus, the Aghānī, was very likely intended for him, as well. As a return for his literary efforts, according to al-Tanūkhī, al-Isfahani frequently received rewards from the vizier. Furthermore, for the sake of their long-term friendship and out of his respect for al-Isfahani's genius, al-Muhallabī exceptionally tolerated al-Isfahani's uncouth manners and poor personal hygiene. The sources say nothing about al-Isfahani's fate, after al-Muhallabī's death. In his last years, according to his student, Muhammad b. Abī al-Fawāris, he suffered from senility (khallaṭa). Personality, preferences, and beliefs As a boon companion, al-Isfahani was unconventional in the sense that he does not seem to have been bothered to observe the social decorum of his time, as noted by a late biographical source: with his uncleanliness and gluttony, he presented a counterexample to elegance (ẓarf), as defined by one of his teachers, Abu al-Ṭayyib al-Washshāʾ (d. 325/937). His unconformity to the social norms did not hinder him from being part of al-Muhallabī's entourage or participation in the literary assemblies, but, inevitably, it resulted in frictions with other scholars and detraction from his enemies. Although al-Isfahani appeared eccentric to his human associates, he was a caring owner to his cat, named Yaqaq (white): he treated Yaqaq's colic (qulanj) with an enema (al-ḥuqna). In contrast to his uncomely modus vivendi, al-Isfahani's prose style is lucid, “in clear and simple language, with unusual sincerity and frankness”. Al-Isfahani's capacity as a litterateur is well illustrated by Abu Deeb, who depicts al-Isfahani as "one of the finest writers of Arabic prose in his time, with a remarkable ability to relate widely different types of aḵbār in a rich, lucid, rhythmic, and precise style, only occasionally exploiting such formal effects as saǰʿ (rhyming prose). He was also a fine poet with an opulent imagination. His poetry displays preoccupations similar to those of other urban poets of his time". His pinpoint documentation of asānīd and meticulous verification of information, provided in all his works, embody a truly scholarly character. Usually, in his treatment of a subject or an event, al-Isfahani lets his sources speak, but, occasionally, he voices his evaluation of poems and songs, as well as their creators. When dealing with conflicting reports, al-Isfahani either leaves his readers to decide or issues his judgment as to the most credible account. Yet, he frankly condemns sources whom he holds to be unreliable, for instance, Ibn Khurdādhbih on musicological information and Ibn al-Kalbī on genealogy. Indeed, al-Isfahani assesses his source material with a critical eye, while striving to present a more balanced view on his biographeis, by focusing on their merits instead of elaborating on their flaws. That said, al-Isfahani's personal preferences and sectarian partisanship are not absent from his works. In terms of music and songs, al-Isfahani is a fan of Ishaq b. Ibrahim al-Mawsili (155–235/772–850). In al-Isfahani's view, Ishaq b. Ibrahim was a multi-talented man, who excelled in a number of subjects, but, most importantly, music. Ishaq b. Ibrahim, as a collector of the reports about poets and singers, is an important source in his Aghānī. Besides being a mine of information, Ishaq b. Ibrahim's terminology for the description of the melodic modes is preferred over that of his opponent, Ibrahim ibn al-Mahdi (162–224/778–839), and adopted by al-Isfahani in his Aghani. Furthermore, al-Isfahani embarked on the compilation of the Aghānī because he was commissioned by his patron to reconstruct the list of the exquisite songs selected by Ishaq. In other words, the raison d’etre of the Aghānī is partly related to al-Isfahani's idol, Ishaq b. Ibrahim, and its information about singers, songs and performance owes a tremendous amount to him. Al-Isfahani's admiration for scholars or men of letters can be detected from time to time, usually in the passing comments in the chains of transmission. Yet al-Isfahani outspokenly expresses his admiration, in some cases, such as that of Ibn al-Muʿtazz (247–296/862–909). As an Umayyad by ancestry, al-Isfahani's later biographers mention his Shi'i affiliation with surprise. Yet, in the light of the history of the family's connections with the Abbasid elite of Shi'i inclination and the Ṭālibids, and of his learning experience in Kūfa, his Shi'i conviction is understandable. Al-Tusi (385–460/995–1067) is the only early source specifying the exact sect to which he pertains in the fluid Shi'i world: al-Isfahani is a Zaydī. Although al-Ṭūsī's view is widely accepted, its veracity is not beyond doubt. Al-Isfahanidoes not seem to have been informed of the latest Zaydī movements in Yemen and Ṭabaristān of his time, while his association with the Kūfan Zaydī community, which to some degree became less distinguishable from the Sunnīs, is yet to be studied in depth. It is clear, based on examination of how al-Isfahani redacts the reports at his disposal, that he does honour Ali, who plays a far more prominent role in his works than the first three caliphs, and some of his descendants, including Zaydi Shi'ism's eponym, Zayd ibn Ali (75–122/694–740), by presenting them positively, while, in some cases, leaving their enemies’ rectitude in question. In spite of that, al-Isfahani is neither keen to identify the imams in the past, nor articulate as to the qualities of an imam.{{efn|The Zaydī writings in the late ninth and early tenth centuries more or less devote discussion to the role and qualities of imam; see, for example: {{sfn|ref=Majmūʿ Rasāʾil|Yaḥyā, Majmūʿ Rasāʾil|p=431–432}} al-Ḥādī ilā al-Ḥaqq also singled out a line of the Zaydi imams up till his time in his Kitab al-Ahkam; see:}} As a matter of fact, he hardly uses the word, not even applying it to Zayd b. Ali. Furthermore, he does not unconditionally approve any Alid revolt and seems somewhat lukewarm towards the group he refers to as Zaydis. Taken together, al-Isfahani's Shi'i conviction is better characterised as moderate love for Ali without impugning the dignity of the caliphs before him. Legacy Al-Isfahani authored a number of works, but only a few survive. Three of them are preserved through the quotations: al-Qiyan ("The Singing Girls Enslaved by Men"), al-Diyarat ("The Monasteries"), and Mujarrad al-aghani (“The Abridgement of the Book of Songs”). A fragment of the Mujarrad al-aghani can be found in Ibn Abi Uṣaybi'a's ʿUyun al-anba' fi tabaqat al-atibbaʾ, which quotes a poem by the caliph, al-Maʾmūn (r. 198–218/813–833), which was arranged as a song by Mutayyam. The first two have been reconstructed and published by al-ʿAtiyya, who collects and collates the passages from later works that quote from al-Isfahani. The former, al-Qiyān, is a collection of the biographies of the enslaved singing girls. In it, al-Isfahani provides the basic information about the biographical subjects, the men who enslaved them, and their interaction with poets, notables such as caliphs, and their admirers, with illustration of their poetic and/or musical talents. The latter, al-Diyārāt, provides information related to monasteries, with the indication of their geographical locations and, sometimes, history and topographical characteristics. However, it is questionable to what extent the reconstructed editions can represent the original texts, since the passages, which quote al-Isfahani as a source for the given subject and are thus included by the editor, seldom identify the titles of the works. Four works survive in manuscripts and have been edited and published: Maqātil al-Ṭālibīyīn ("The Ṭālibid Martyrs"), Kitab al-Aghani ("The Book of the Songs"), Adab al-ghuraba ("The Etiquettes of the Strangers"), and al-Ima al-shawair ("The Enslaved Women Who Composed Poetry"). As noted above, al-Isfahani's authorship of the Adab al-ghurabaʾ is disputed. The author, whoever he may have been, mentions in the preface his sufferings from the hardship of time and vicissitude of fate, and the solace which he seeks through the stories of bygone people. Hence, he collects in the Adab al-ghuraba the reports about the experiences of strangers — those away from their homes or their beloved ones. Some of the stories centre on the hardship which strangers, anonymous or not, encountered in their journey or exile, usually shown in the epigrams written on monuments, rocks, or walls. Others relate excursions to the monasteries for drinking. The al-Imāʾ al-shawāʿir was composed at the order of the vizier al-Muhallabī, al-Isfahani's patron, who demanded collection of the reports about the enslaved women who composed poetry from the Umayyad to the Abbasid periods. Al-Isfahani confesses that he could not find any noteworthy poetess in the Umayyad period, because the people at that time were not impressed with the verses featuring tenderness and softness. Thus, he only records the Abbasid poetesses, with mention of the relevant fine verses or the pleasant tales, and arranges them in chronological order. There are 31 sections, addressing 32 poetesses, most of which are short and usually begin with al-Isfahani's summary of the subject. The Maqātil al-Ṭālibīyīn is a historical-biographical compilation concerning the descendants of Abu Talib, who died under the following circumstances: being killed, poisoned to death in a treacherous way, on the run from the rulers’ persecution, or confined until death. The Maqātil literature was rather common, amongst Shi'is particularly, before al-Isfahani and he used many works of this genre as sources for the Maqātil al-Ṭālibīyīn. Al-Isfahani does not explain the motivation behind this compilation nor mention any dedicatee, but, according to the preface of this work, he sets out as a condition to recount the reports about the Ṭālibids who were “praiseworthy in their conduct and rightly guided in their belief (maḥmūd al-ṭarīqa wa-sadīd al-madhhab)”. Like the al-Imāʾ, the work is structured in chronological order, beginning with the first Ṭālibī martyr, Jaʿfar b. Abī Ṭālib, and ends in the year of its compilation — Jumādā I 313/August 925. For each biographical entry, al-Isfahani gives the full name, the lineage (sometimes adding the maternal side). Less often, he additionally gives the virtues and personal traits of the subject and other material he thinks noteworthy, for example the prophetic ḥadīth about, or transmitted by, the subject of the biography in question. Then, al-Isfahani gives the account of the death, which more often than not constitutes the end of the entry. Sometimes poetry for or by the subject is attached. The Maqātil was adduced by many Shi'i and non-Shi'i compilers of the following centuries. The Kitab al-Aghani, al-Isfahanis best known work, is an immense compilation, including songs provided with musical indications (melodic modes and meters of songs), the biographies of poets and musicians of different periods in addition to historical material. As noted above, al-Isfahani embarks on compiling the Aghani first under the command of a patron, whom he calls ra'is (chief), to reconstruct the list of one hundred fine songs, selected by Ishaq b. Ibrahim. Due to an obscure report in Yaqut's Mu'jam, this raʾīs is often assumed to be Sayf al-Dawla al-Ḥamdānī (r. 333–356/945–967), but recent studies suggest that a more plausible candidate for the dedicatee of the Aghani is the vizier al-Muhallabī. The Aghani is divided into three parts: first, The Hundred Songs (al-mi'a al-ṣawt  al-mukhtara) and other song collections; second, the songs of the caliphs and of their children and grandchildren (aghani al-khulafa wa-awladihim wa-awlad awladihim); third, al-Isfahanis selection of songs. The articles in each part are arranged based on different patterns, but it is mostly the song which introduces the articles on biographies or events. The Kitab al-Aghani is not the first book or collection of songs in Arabic, but one can assert that it is the most important one, for it "is a unique mine of information not only on hundreds of song texts with their modes and meters, but also on the lives of their poets and composers, and on the social context of music making in early Islam and at the courts of the caliphs in Damascus and Baghdad". Because of al-Isfahanis pedantic documentation of his sources, the Kitab al-Aghani can also be used to reconstruct earlier books of songs or biographical dictionaries on musicians that are otherwise lost. As for the works that did not survive, based on their contents, as implied by their titles, they can be divided into the following categories: The genealogical works: Nasab Bani Abd Shams ("The Genealogy of the Banu Abd Shams"), Jamharat al-nasab ("The Compendium of Genealogies"), Nasab Bani Shayban ("The Genealogy of the Banu Shayban"), and Nasab al-Mahaliba ("The Genealogy of the Muhallabids"), this last probably dedicated to his patron, the vizier al-Muhallabi. The reports about specified or unspecified topics, such as Kitab al-Khammarin wa-l-khammarat ("The Book of Tavern-Keepers, Male and Female"), Akhbar al-tufayliyin ("Reports about Party Crashers"), al-Akhbar wa-l-nawadir ("The Reports and Rare Tales"), and Ayyam al-arab ("The Battle-Days of the Arabs"), which mentions 1700 days of the pre-Islamic tribal battles and was in circulation only in Andalusia. The reports about music, musicians and singers: the aforementioned Manajib al-khisyan ("The Noble Eunuchs"), Akhbzr Jahza al-Barmaki ("The Reports concerning Jahza al-Barmaki"), al-Mamalik al-shu'ara ("The Slave Poets"), Adab al-samz ("The Etiquettes of Listening to Music"), and Risala fi 'ilal al-nagham ("The Treatise on the Rules of Tones"). There are two works, only mentioned by al-Tusi: Kitab ma nazala min al-Qur'an fi amir al-mu'minīn wa-ahl baytih 'alayhim al-salam ("The Book about the Qur'anic Verses Revealed regarding the Commander of the Faithful and the People of His Family, Peace upon Them") and Kitab fihi kalam Fatima alayha al-salam fi Fadak ("The Book concerning the Statements of Fāṭima, Peace upon Her, regarding Fadak"). Should the attribution of these two works to al-Isfahani be correct, together with the Maqatil al-Talibiyin, they reveal al-Isfahanis Shi'i partisanship. Works Al-Isfahani is best known as the author of Kitab al-Aghani ("The Book of Songs"), an encyclopedia of over 20 volumes and editions. However, he additionally wrote poetry, an anthology of verses on the monasteries of Mesopotamia and Egypt, and a genealogical work.Kitāb al-Aġānī () 'Book of Songs', a collection of Arabic chants rich in information on Arab and Persian poets, singers and other musicians from the 7th - 10th centuries of major cities such as Mecca, Damascus, Isfahan, Rey, Baghdād and Baṣrah. The Book of Songs contains details of the ancient Arab tribes and courtly life of the Umayyads and provides a complete overview of the Arab civilization from the pre-Islamic Jahiliyya era, up to his own time. Abu ‘l-Faraj employs the classical Arabic genealogical devise, or isnad, (chain of transmission), to relate the biographical accounts of the authors and composers. Although originally the poems were put to music, the musical signs are no longer legible. Abu ‘l-Faraj spent in total 50 years creating this work, which remains an important historical source. The first printed edition, published in 1868, contained 20 volumes. In 1888 Rudolf Ernst Brünnow published a 21st volume being a collection of biographies not contained in the Bulāq edition, edited from MSS in the Royal Library of Munich.Maqātil aṭ-Ṭālibīyīn (}), Tālibid Fights, a collection of more than 200 biographies of the descendants of Abu Talib ibn Abd al-Muttalib, from the time of the Prophet Muhammad to the writing of the book in 313 the Hijri (= 925/926 CE) who died in an unnatural way. As Abul-Faraj said in the foreword to his work, he included only those Tālibids who rebelled against the government and were killed, slaughtered, executed or poisoned, lived underground, fled or died in captivity. The work is a major source for the Umayyad and Abbāsid Alid uprisings and the main source for the Hashimite meeting that took place after the assassination of the Umayyad Caliph al-Walīd II in the village of al-Abwā' between Mecca and Medina. At this meeting, al-'Abdallah made the Hashimites pledge an oath of allegiance to his son Muhammad al-Nafs al-Zakiyya as the new Mahdi.

Alcobaça, Portugal

Alcobaça () is a city and a municipality in the Leiria District, of Central Portugal. The city grew along the valleys of the rivers Alcoa and Baça, from which it derives its name. The municipality population in 2011 was 56,693, in an area of . The city proper has a population of 15,800 inhabitants. The city of Alcobaça became notable after the first king of Portugal, Afonso Henriques, decided to build a church to commemorate the Conquest of Santarém from the Moors in 1147. The church later evolved into the Monastery of Alcobaça, one of the most magnificent gothic monuments in the country. In the church are the tombs of Pedro I of Portugal and his murdered mistress Inês de Castro. Over the centuries this monastery played an important role in shaping Portuguese culture. A few kilometers to the north of Alcobaça is the Monastery of Batalha, another gothic building constructed in memory of a different important battle, that of Aljubarrota. To the west of Alcobaça is the fishing village of Nazaré, now a popular resort town. To the south is the city of Caldas da Rainha and the medieval town of Óbidos. Also to the northeast is the town of Porto de Mós with its rebuilt castle. History A town that only became notable in the 12th century when it was chosen as the future site of Portugal's largest church. In March 1147, the fledgling King Dom Afonso Henriques, defeated the Moors by capturing the city of Santarém. As a tribute to his victory he vowed to build a magnificent home for the Order of Cistercians. It took another 76 years before this task was completed. The monarchy continued to carry out further construction and 60 years later King Dinis built the main cloister. The Monastery was consecrated in 1262. The church contains the tombs of Pedro I of Portugal and his murdered mistress Inês de Castro and with it the story of the tragic liaison between Pedro and Inês. Forced at an early age as a royal duty, he was to marry Constanza, the Infanta (Princess) of Castile, but died shortly after the marriage. Dom Pedro escape with his true love and later lived in the city of Coimbra. His father, King Afonso IV, believing that the family of Inês was a threat to his own kingdom had her murdered. Shortly after the death of his father Dom Pedro declared that he had married Inês in a prior secret ceremony in Bragança, and promptly took a gruesome revenge on the killers and exhumed her body. He presented the embalmed corpse at the court with a crown on her head and demanded that all his courtiers kneel and individually pay homage to her decomposed hand. Today, their ornate tombs face each other so that on Judgment Day his first sight would be of his beloved Inês. During the following centuries the monks from this monastery had a major influence on the development of Portuguese culture. Notably, in 1269 they were the first to give public lessons to their flock, and later they produced the first authoritative history on Portugal in a series of books. In 1810 the invading French pillaged the Abbey taking with them most of its most important treasures, including the noteworthy library. The items that remained were later stolen in 1834 during an anti-clerical riot and the banning of the religious Orders in Portugal. Climate Alcobaça has a Mediterranean climate (Köppen:Csb) with warm, dry summers and mild, wet winters. Parishes Administratively, the municipality is divided into 13 civil parishes (freguesias): Alcobaça e Vestiaria Alfeizerão Aljubarrota Bárrio Benedita Cela Coz, Alpedriz e Montes Évora de Alcobaça Maiorga Pataias e Martingança São Martinho do Porto Turquel Vimeiro City information The main feature of the city is essentially the monastery that proudly presents a long and sombre façade with 18th-century embellishments. This austerity is further emphasized in the cloisters with its apt name of "Cloister of Silence". In contrast within the Abbey is the massive kitchen with a running stream specially diverted to pass through as a supply of fresh water. The open area of the kitchen chimney is large enough to take a whole ox for roasting. The surround to the sacristy doorway is an outstanding example of Manueline decoration. In 1794, Lord Beckford visited the Abbey and commented that he found some 300 monks "living in a very splendid manner"! Nearby locations A few kilometers to the north of Alcobaça is another wondrous building constructed in memory of a different important battle, that of Aljubarrota in 1385, when King John I of Portugal defeated the Castilians and ensuring two hundred years of independence from the Castilian invaders. The construction of the Abbey at Batalha commenced in 1388 and was added to by various Portuguese Kings over these next two centuries. To the east of Batalha is the world-famous location of Fátima and a point of pilgrimage for the Roman Catholic religion due to the vision of the Virgin Mary in 1917 by three young children whilst tending their flock. To the west of Alcobaça is the well-known fishing village of Nazaré. Today, the village is now a small town and a popular holiday resort with most of its past and traditions having rapidly evaporated in the course of time. A very successful Portuguese feature film was made in the early 20th century that dramatically captured the primitive and dangerous life of these fishermen. Stoutly Catholic, the inhabitants have retained some of their past as can be still seen in their own particular style of costume. To the south is Caldas da Rainha and the quaint medieval town of Óbidos that is an attraction for any tourists that enjoys a true glimpse of the past. Also to the south is the town of Porto de Mós with its fanciful rebuilt castle. This town borders the Nature Reserve Parque Natural das Serras de Aire e Candeeiros. These 390 square kilometres of limestone-covered landscape is also known for its caverns. The best known being the Grutas de Mira de Aire can be visited and consists of tunnels, caverns with stalactites, stalagmites, lakes, and a music and light finale.

https://en.wikipedia.org/wiki/Amphisbaena

Amphisbaena

The amphisbaena (, , or , plural: amphisbaenae; ) is a mythological, ant-eating serpent with a head at each end. The creature is alternatively called the amphisbaina, amphisbene, amphisboena, amphisbona, amphista, amfivena, amphivena, or anphivena (the last two being feminine), and is also known as the "Mother of Ants". Its name comes from the Greek words amphis, meaning "both ways", and bainein, meaning "to go". Mythology According to Greek mythology, the amphisbaena was spawned from the blood that dripped from the Gorgon Medusa's head as Perseus flew over the Libyan Desert with her head in his hand, after which Cato's army then encountered it along with other serpents on the march. Amphisbaena fed on the corpses left behind. The amphisbaena has been referred to by various poets such as Nicander, John Milton, Alexander Pope, Percy Bysshe Shelley, Alfred, Lord Tennyson, Aimé Césaire, A. E. Housman and Allen Mandelbaum; as a mythological and legendary creature, it has been referenced by Lucan, Pliny the Elder, Isidore of Seville, and Thomas Browne, the last of whom debunked its existence. Appearance These early descriptions of the amphisbaena depicts a venomous, dual-headed snakelike creature. However, Medieval and later drawings often show it with two or more scaled feet, particularly chicken feet, and feathered wings. Some even depict it as a horned, dragon-like creature with a serpent-headed tail and small, round ears, while others have both "necks" of equal size so that it cannot be determined which is the rear head. Many descriptions of the amphisbaena say its eyes glow like candles or lightning, but the poet Nicander seems to contradict this by describing it as "always dull of eye". He also says: "From either end protrudes a blunt chin; each is far from each other." Nicander's account seems to be referring to what is indeed called the Amphisbaenia, a group of real lizards. Habitat The amphisbaena is said to make its home in the desert. Folk medicine In ancient times, the supposedly dangerous amphisbaena had many uses in the art of folk medicine and other such remedies. Pliny notes that expecting women wearing a live amphisbaena around their necks would have safe pregnancies; however, if one's goal was to cure ailments such as arthritis or the common cold, one should wear only its skin. By eating the meat of the amphisbaena, one could supposedly attract many lovers of the opposite sex, and slaying one during the full moon could give power to one who is pure of heart and mind. Lumberjacks suffering from cold weather on the job could nail its carcass or skin to a tree to keep warm, while in the process allowing the tree to be felled more easily. Origins In The Book of Beasts, T.H. White suggests that the creature derives from sightings of the worm lizards of the same name. These creatures are found in the Mediterranean countries where many of these legends originated. In media In John Milton's Paradise Lost, after the Fall and the return of Satan to Hell, some of the fallen angelic host are transformed into the amphisbaena, to represent the animal by which the Fall was caused, i.e. a snake. The amphisbaena is mentioned in the first book of Andrzej Sapkowski's The Witcher series, i.e. The Last Wish, when The Witcher'''s protagonist, Geralt of Rivia, is recalling past events when he meets an old acquaintance named Irion. The amphisbaena was endangering the region of Kovir until the beast was slain by Geralt's hand. Brandon Sanderson's novel Skyward has a character whose name is Arturo Mendez. His call sign is amphisbaena. In the 1984 Scandinavian animated film Gallavants, an amphisbaena (called a 'Vanterviper' in the film) appears as a minor antagonist. The two heads, a red one named Edil and a blue one called Fice, frequently disagree and argue, and sing a song about their miserable plight. Amphisbaena appears in some editions of the tabletop roleplaying game Dungeons & Dragons. The Amphisbaena appears in the Rise of the Teenage Mutant Ninja Turtles episode "Battle Nexus: New York." This version is one of the known champions of the Battle Nexus. Big Mama had Michelangelo and Meat Sweats compete to feed each of its heads in order to satisfy the amphisbaena. They managed to work together to pull it off. Amphisbaena has appeared in several video games as an enemy or boss monster, including La-Mulana and Bravely Second: End Layer. A creature called Amphisbaena appears in the games Castlevania: Symphony of the Night and Castlevania: Portrait of Ruin but bears little resemblance to other renditions of the creature, appearing as an eyeless 4-legged reptile with the upper body of a human woman sprouting from its long tail instead of a double-headed serpent. Amphisbaena appeared in an animation created by Monty Oum, in the form of an evil creature called Grimm. Of the different Grimm, the Amphisbaena appears to be the King Taijitu, a two-headed snake or serpent. The king's name references the taijitu, a symbol or diagram in Chinese philosophy representing Taiji in both its monist and dualist aspects. The Grimm's coloration visually symbolizes the taijitu, with one head and body section black and the opposite side white.

https://en.wikipedia.org/wiki/Amyl%20alcohol

Amyl alcohol

An amyl alcohol is any of eight alcohols with the formula C5H12O. A mixture of amyl alcohols (also called amyl alcohol) can be obtained from fusel alcohol. Amyl alcohol is used as a solvent and in esterification, by which is produced amyl acetate and other important products. The name amyl alcohol without further specification applies to the normal (straight-chain) form, 1-pentanol. These are the 8 alcohols that are structural isomers with molecular formula C5H12O: {| class="wikitable sortable" |+Amyl alcohol isomers |- ! Common name !! Structure !! Type !! IUPAC name !! Boiling point (°C) |- | 1-pentanolor normal amyl alcohol | | primary | Pentan-1-ol | 138.5 |- | 2-methyl-1-butanolor active amyl alcohol | | primary | 2-Methylbutan-1-ol | 128.7 |- | 3-methyl-1-butanolor isoamyl alcoholor isopentyl alcohol | | primary | 3-Methylbutan-1-ol | 131.2 |- | 2,2-dimethyl-1-propanolor neopentyl alcohol | | primary | 2,2-Dimethylpropan-1-ol | 113.1 |- | 2-pentanolor sec-amyl alcoholor methyl (n) propyl carbinol | | secondary | Pentan-2-ol | 118.8 |- | 3-methyl-2-butanolor sec-isoamyl alcoholor methyl isopropyl carbinol | | secondary | 3-Methylbutan-2-ol | 113.6 |- | 3-Pentanol | | secondary | Pentan-3-ol | 115.3 |- | 2-methyl-2-butanolor tert-amyl alcohol | | tertiary | 2-Methylbutan-2-ol | 102 |} Three of these alcohols, 2-methyl-1-butanol, 2-pentanol, and 3-methyl-2-butanol (methyl isopropyl carbinol), are therefore optically active. The most important amyl alcohol is isoamyl alcohol, the chief one generated by fermentation in the production of alcoholic beverages and a constituent of fusel oil. The other amyl alcohols may be obtained synthetically. Notes Alkanols GABAA receptor positive allosteric modulators

https://en.wikipedia.org/wiki/Amyl%20nitrite

Amyl nitrite

Amyl nitrite is a chemical compound with the formula C5H11ONO. A variety of isomers are known, but they all feature an amyl group attached to the nitrite functional group. The alkyl group is unreactive and the chemical and biological properties are mainly due to the nitrite group. Like other alkyl nitrites, amyl nitrite is bioactive in mammals, being a vasodilator, which is the basis of its use as a prescription medicine. As an inhalant, it also has a psychoactive effect, which has led to its recreational use, with its smell being described as that of old socks or dirty feet. It is also referred to as banapple gas. It was first documented in 1844 and came into medical use in 1867. Uses Amyl nitrite is employed medically to treat heart diseases as well as angina. Amyl nitrite is sometimes used as an antidote for cyanide poisoning. It can act as an oxidant, to induce the formation of methemoglobin. Methemoglobin in turn can sequester cyanide as cyanomethemoglobin. Amyl nitrite is used as a cleaning agent and solvent in industrial and household applications. It replaced dichlorodifluoromethane, an industrial chemical universally banned in 1996 due to damage to the ozone layer, as a printed circuit board cleaner. Trace amounts are added to some perfumes. It is also used recreationally as an inhalant drug that induces a brief euphoric state, and when combined with other intoxicant stimulant drugs such as cocaine or MDMA, the euphoric state intensifies and is prolonged. Once some stimulative drugs wear off, a common side effect is a period of depression or anxiety, colloquially called a "come down"; amyl nitrite is sometimes used to combat these negative after-effects. This effect, combined with its dissociative effects, has led to its use as a recreational drug (see poppers). Nomenclature The term "amyl nitrite" encompasses several isomers. In older literature, the common non-systematic name amyl was often used for the pentyl group, where the amyl group is a linear or normal (n) alkyl group, and the resulting amyl nitrite would have the structural formula CH3(CH2)4ONO, also referred to as n-amyl nitrite. A common form of amyl nitrite is the isomer with the formula (CH3)2CHCH2CH2ONO, which may be more specifically referred to as isoamyl nitrite. The similarly named amyl nitrate has very different properties. At the same time, isopropyl nitrite has a similar structure and similar uses (also called 'poppers') but with worse side-effects. Synthesis and reactions Alkyl nitrites are prepared by the reaction of alcohols with nitrous acid: ROH + HONO → RONO + H2O, where R = alkyl group The reaction is called esterification. Synthesis of alkyl nitrites is, in general, straightforward and can be accomplished in home laboratories. A common procedure includes the dropwise addition of concentrated sulfuric acid to a cooled mixture of an aqueous sodium nitrite solution and an alcohol. The intermediately-formed stoichiometric mixture of nitrogen dioxide and nitric oxide then converts the alcohol to the alkyl nitrite, which, due to its low density, will form an upper layer that can be easily decanted from the reaction mixture. Isoamyl nitrite decomposes in the presence of base to give nitrite salts and the isoamyl alcohol: C5H11ONO + NaOH → C5H11OH + NaNO2 Amyl nitrite, like other alkyl nitrites, reacts with carbanions to give oximes. Amyl nitrites are also useful as reagents in a modification of the Sandmeyer reaction. The reaction of the alkyl nitrite with an aromatic amine in a halogenated solvent produces a radical aromatic species, this then frees a halogen atom from the solvent. For the synthesis of aryl iodides diiodomethane is used, whereas bromoform is the solvent of choice for the synthesis of aryl bromides. Physiological effects Amyl nitrite, in common with other alkyl nitrites, is a potent vasodilator; it expands blood vessels, resulting in lowering of the blood pressure. Amyl nitrite may be used during cardiovascular stress testing in patients with suspected hypertrophic cardiomyopathy to cause vasodilation and thereby reduce afterload and provoke obstruction of blood flow towards the aorta from the ventricle by increasing the pressure gradient, thereby causing left ventricular outflow obstruction. Alkyl nitrites are a source of nitric oxide, which signals for relaxation of the involuntary muscles. Physical effects include decrease in blood pressure, headache, flushing of the face, increased heart rate, dizziness, and relaxation of involuntary muscles, especially the blood vessel walls and the internal and external anal sphincter. There are no withdrawal symptoms. Overdose symptoms include nausea, vomiting, hypotension, hypoventilation, shortness of breath, and fainting. The effects set in very quickly, typically within a few seconds and disappear within a few minutes. Amyl nitrite may also intensify the experience of synesthesia. Amyl nitrate, when given as a medication for patients with angina can also be administered as an ampule. The ampule is put a gauze pad and then inhaled by the patient during an angina attack and repeated every fifteen minutes. However, oral dosing of amyl nitrate is ineffective due to poor absorption and extensive hepatic metabolism. it has been discontinued, and that has been associated with the dominance of Nitroglycerin in the pharmaceutical market. Toxicity Although there are case reports of life-threatening toxicity involving unusually large amounts, typical inhaled doses of amyl nitrite are considered relatively safe. However, liquid amyl nitrite is highly toxic when ingested because of the unsafely high concentration it effects in blood. Regardless of the form or route of administration, acute toxicity principally results when the nitrite oxidizes a significant proportion of hemoglobin in the blood without oxygen, forming methemoglobin, which cannot carry oxygen. Severe poisoning cases will progress to methemoglobinemia, characterized by a blue-brown discoloration under the skin which could be mistaken for cyanosis. Treatment with oxygen and intravenous methylene blue frustrates visual confirmation further as methylene blue itself is, as its name suggests, a blue dye; the patient's changes in different shades of blue notwithstanding, it is an effective antidote by way of catalyzing the production of the enzyme responsible for reducing the methemoglobin in the blood back to hemoglobin. The discoloration does mean that regular near-infrared–based pulse oximetry becomes useless. More fundamentally, blood gas analysis on the whole has limited effectiveness, as the increased methemoglobin level increases the oxygen binding affinity of regular hemoglobin. Therefore, the measurement of actual ratios and levels of methemoglobin and hemoglobin must accompany any blood gas partial pressure sample in these cases.

Autumn

Autumn, also known as fall in North American English, is one of the four temperate seasons. Outside the tropics, autumn marks the transition from summer to winter, in September (Northern Hemisphere) or March (Southern Hemisphere). Autumn is the season when the duration of daylight becomes noticeably shorter and the temperature cools considerably. Day length decreases and night length increases as the season progresses until the Winter Solstice in December (Northern Hemisphere) and June (Southern Hemisphere). One of its main features in temperate climates is the striking change in colour for the leaves of deciduous trees as they prepare to shed. Some cultures regard the autumnal equinox as "mid-autumn", while others with a longer temperature lag treat the equinox as the start of autumn. In the English-speaking world, autumn traditionally began with Lammas Day and ended around Hallowe'en, the approximate mid-points between midsummer, the autumnal equinox, and midwinter. Meteorologists (and Australia and most of the temperate countries in the southern hemisphere) use a definition based on Gregorian calendar months, with autumn being September, October, and November in the northern hemisphere, and March, April, and May in the southern hemisphere. In North America, autumn traditionally starts with the September equinox (21 to 24 September) and ends with the winter solstice (21 or 22 December). Popular culture in the United States associates Labor Day, the first Monday in September, as the end of summer and the start of autumn; certain summer traditions, such as wearing white, are discouraged after that date. As daytime and nighttime temperatures decrease, trees change colour and then shed their leaves. In traditional East Asian solar term, autumn starts on or around 8 August and ends on or about 7 November. In Ireland, the autumn months according to the national meteorological service, Met Éireann, are September, October and November. However, according to the Irish Calendar, which is based on ancient Gaelic traditions, autumn lasts throughout the months of August, September and October, or possibly a few days later, depending on tradition. In the Irish language, September is known as ("middle of autumn") and October as ("end of autumn"). Persians celebrate the beginning of the autumn as Mehregan to honor Mithra (Mehr). Etymology The word autumn () is derived from Latin autumnus, archaic auctumnus, possibly from the ancient Etruscan root autu- and has within it connotations of the passing of the year. Alternative etymologies include Proto-Indo-European *h₃ewǵ- ("cold") or *h₂sows- ("dry"). After the Greek era, the word continued to be used as the Old French word ( in modern French) or in Middle English, and was later normalised to the original Latin. In the Medieval period, there are rare examples of its use as early as the 12th century, but by the 16th century, it was in common use. Before the 16th century, harvest was the term usually used to refer to the season, as it is common in other West Germanic languages to this day (cf. Dutch , German and Scots ). However, as more people gradually moved from working the land to living in towns, the word harvest lost its reference to the time of year and came to refer only to the actual activity of reaping, and autumn, as well as fall, began to replace it as a reference to the season. The alternative word fall for the season traces its origins to old Germanic languages. The exact derivation is unclear, with the Old English or and the Old Norse all being possible candidates. However, these words all have the meaning "to fall from a height" and are clearly derived either from a common root or from each other. The term came to denote the season in 16th-century England, a contraction of Middle English expressions like "fall of the leaf" and "fall of the year". Compare the origin of spring from "spring of the leaf" and "spring of the year". During the 17th century, English emigration to the British colonies in North America was at its peak, and the new settlers took the English language with them. While the term fall gradually became nearly obsolete in Britain, it became the more common term in North America. The name backend, a once common name for the season in Northern England, has today been largely replaced by the name autumn. Associations Harvest Association with the transition from warm to cold weather, and its related status as the season of the primary harvest, has dominated its themes and popular images. In Western cultures, personifications of autumn are usually pretty, well-fed females adorned with fruits, vegetables and grains that ripen at this time. Many cultures feature autumnal harvest festivals, often the most important on their calendars. Still-extant echoes of these celebrations are found in the autumn Thanksgiving holiday of the United States and Canada, and the Jewish Sukkot holiday with its roots as a full-moon harvest festival of "tabernacles" (living in outdoor huts around the time of harvest). There are also the many festivals celebrated by indigenous peoples of the Americas tied to the harvest of ripe foods gathered in the wild, the Chinese Mid-Autumn or Moon festival, and many others. The predominant mood of these autumnal celebrations is a gladness for the fruits of the earth mixed with a certain melancholy linked to the imminent arrival of harsh weather. This view is presented in English poet John Keats' poem To Autumn, where he describes the season as a time of bounteous fecundity, a time of 'mellow fruitfulness'. In North America, while most foods are harvested during the autumn, foods usually associated with the season include pumpkins (which are integral parts of both Thanksgiving and Halloween) and apples, which are used to make the seasonal beverage apple cider. Melancholia Autumn, especially in poetry, has often been associated with melancholia. The possibilities and opportunities of summer are gone, and the chill of winter is on the horizon. Skies turn grey, the amount of usable daylight drops rapidly, and many people turn inward, both physically and mentally. It has been referred to as an unhealthy season. Similar examples may be found in Irish poet W.B. Yeats' poem The Wild Swans at Coole where the maturing season that the poet observes symbolically represents his own ageing self. Like the natural world that he observes, he too has reached his prime and now must look forward to the inevitability of old age and death. French poet Paul Verlaine's "Chanson d'automne" ("Autumn Song") is likewise characterised by strong, painful feelings of sorrow. Keats' To Autumn, written in September 1819, echoes this sense of melancholic reflection but also emphasises the lush abundance of the season. The song "Autumn Leaves", based on the French song "Les Feuilles mortes", uses the melancholic atmosphere of the season and the end of summer as a metaphor for the mood of being separated from a loved one. Halloween Autumn is associated with Halloween (influenced by Samhain, a Celtic autumn festival), and with it a widespread marketing campaign that promotes it. The Celtic people also used this time to celebrate the harvest with a time of feasting. At the same time though, it was a celebration of death as well. Crops were harvested, livestock were butchered, and Winter was coming. Halloween, 31 October, is in autumn in the northern hemisphere. Television, film, book, costume, home decoration, and confectionery businesses use this time of year to promote products closely associated with such a holiday, with promotions going from late August or early September to 31 October, since their themes rapidly lose strength once the holiday ends, and advertising starts concentrating on Christmas. Other associations In some parts of the northern hemisphere, autumn has a strong association with the end of summer holiday and the start of a new school year, particularly for children in primary and secondary education. "Back to School" advertising and preparations usually occurs in the weeks leading to the beginning of autumn. Carnival, Easter and the International Workers' Day falls in autumn in the southern hemisphere. Thanksgiving Day is a national holiday celebrated in Canada, in the United States, in some of the Caribbean islands and in Liberia. Thanksgiving is celebrated on the second Monday of October in Canada and on the fourth Thursday of November in the United States, and around the same part of the year in other places. Similarly named festival holidays occur in Germany and Japan. Television stations and networks, particularly in North America, traditionally begin their regular seasons in their autumn, with new series and new episodes of existing series debuting mostly during late September or early October (series that debut outside the autumn season are usually known as mid-season replacements). A sweeps period takes place in November to measure Nielsen Ratings. American football is played almost exclusively in the autumn months; at the high school level, seasons run from late August through early November, with some playoff games and holiday rivalry contests being played as late as Thanksgiving. In many American states, the championship games take place in early December. College football's regular season runs from September through November, while the main professional circuit, the National Football League, plays from September through to early January. Summer sports, such as association football (in Northern America, East Asia, Argentina and South Africa), Canadian football, stock car racing, tennis, golf, cricket, and professional baseball, wrap up their seasons in early to late autumn; Major League Baseball's championship World Series is known popularly as the "Fall Classic". (Amateur baseball is usually finished by August.) Likewise, professional winter sports, such as ice hockey and basketball, and most leagues of association football in Europe, are in the early stages of their seasons during autumn; American college basketball and college ice hockey play teams outside their athletic conferences during the late autumn before their in-conference schedules begin in winter. The Christian religious holidays of All Saints' Day and All Souls' Day are observed in autumn in the Northern hemisphere. Since 1997, Autumn has been one of the top 100 names for girls in the United States. In Indian mythology, autumn is considered to be the preferred season for the goddess of learning Saraswati, who is also known by the name of "goddess of autumn" (Sharada). In Asian mysticism, Autumn is associated with the element of metal, and subsequently with the colour white, the White Tiger of the West, and death and mourning. Tourism Although colour change in leaves occurs wherever deciduous trees are found, coloured autumn foliage is noted in various regions of the world: most of North America, Eastern Asia (including China, Korea, and Japan), Europe, southeast, south and part of the midwest of Brazil, the forest of Patagonia, eastern Australia and New Zealand's South Island. Eastern Canada and New England are famous for their autumnal foliage, and this attracts major tourism (worth billions of US dollars) for the regions.

Alameda, California

Alameda ( ; ; Spanish for "tree-lined path") is a city in Alameda County, California, United States. It spans Alameda Island, Bay Farm Island, and a few minor islands. It is adjacent to and south of Oakland and east of San Francisco across the San Francisco Bay. Bay Farm Island, a portion of which is also known as "Harbor Bay Isle", is part of the mainland adjacent to Oakland International Airport. The city's estimated 2019 population was 77,624. Alameda is a charter city, rather than a general law city, and adopted a council–manager government in 1916. History Early history and settlement Alameda occupies what was originally a peninsula connected to Oakland. Much of it was low-lying and marshy. The higher ground nearby and adjacent parts of what is now downtown Oakland were the site of one of the largest coastal oak forests in the world. Spanish colonists called the area Encinal, meaning "forest of evergreen oak". Alameda is Spanish for "grove of poplar trees" or "tree-lined avenue." It was chosen as the name of the city in 1853 by popular vote. The inhabitants at the time of the arrival of the Spanish in the late 18th century were a local band of the Ohlone tribe. The peninsula was included in the vast Rancho San Antonio granted in 1820 to Luis Peralta by the Spanish king who claimed California. The grant was later confirmed by the Republic of Mexico upon its independence in 1821 from Spain. Over time, the place became known as Bolsa de Encinal or Encinal de San Antonio. City development The city was founded on June 6, 1853, after the United States acquired California following the Mexican-American War of 1848. The town originally contained three small settlements. "Alameda" referred to the village at Encinal and High streets, Hibbardsville was located at the North Shore ferry and shipping terminal, and Woodstock was on the west near the ferry piers of the South Pacific Coast Railroad and the Central Pacific. Eventually, the Central Pacific's ferry pier became the Alameda Mole, featuring transit connections among the San Francisco ferries, local trollies, and Southern Pacific (formerly Central Pacific) commuter lines. The first post office opened in 1854. The first school, Schermerhorn School, was opened in 1855 (and eventually renamed as Lincoln School); Encinal School was opened in 1860 (and closed in 1980). The San Francisco and Alameda Railroad opened the Encinal station in 1864. The Encinal area was also known as Fasskings Station in honor of Frederick Louis Fassking. Encinal's own post office opened in 1876, was renamed West End in 1877, and closed in 1891. The West End area was originally called Bowman's Point in honor of Charles G. Bowman, an early United States settler. On September 6, 1869, the Alameda Terminal made history; it was the site of the arrival of the first train via the First Transcontinental Railroad to reach the shores of San Francisco Bay, thus achieving the first coast to coast transcontinental railroad in North America. The transcontinental terminus was switched to the Oakland Pier two months later, on November 8, 1869. The borders of Alameda were made coextensive with the island in 1872, incorporating Woodstock into Alameda. In his autobiography, writer Mark Twain described Alameda as "The Garden of California." Neptune Beach In 1917, a private entertainment park called Neptune Beach was built in the area now known as Crab Cove. Often compared to Coney Island in Brooklyn, New York, the park was a major recreation destination in the 1920s and 1930s. The original owners, the Strehlow family, partnered with a local confectioner to create treats unique to Neptune Beach. Both the American snow cone and the popsicle were first sold at Neptune Beach. The Kewpie doll, hand-painted and dressed in unique hand-sewn dresses, became the original prize for winning games of chance at the beach – another Neptune Beach innovation. The Strehlows owned and operated the beach on their own. They filled in a section of the bay to add an additional Olympic-size swimming pool and a roller coaster, which must have given riders a tremendous view of the bay. The Cottage Baths were available for rent. Neptune Beach's two large outdoor pools hosted swimming races and exhibitions by such notable swimmers such as Olympian Johnny Weissmuller and Jack LaLanne. Weissmuller later starred in films as the original Tarzan character. LaLanne started a longlasting chain of health clubs and appeared on television. The park closed down in 1939 because the Great Depression left many people without much money, the completion of the San Francisco–Oakland Bay Bridge changed traffic patterns, people avoided paying the admission price, and the rise of car culture gave people many more choices for recreation destinations. Once the Bay Bridge was complete, the rail lines, which ran past the entrance to Neptune Beach on the way to the Alameda Mole and the Ferry, lost passengers in great number as people shifted to automobiles. People began using their cars to escape the city and the close suburbs like Alameda and traveled further afield in California. More distant locations appealed to cash-rich San Francisco tourists in the postwar years. Youngsters in town became aware of ways to avoid paying the dime for admission to the park. Strong swimmers or waders could sneak in on the bayside just by swimming around the fence. Some resort homes and buildings from the Neptune Beach era still exist in present-day Alameda. The Croll Building, on the corner of Webster Street and Central Avenue, was the site of Croll's Gardens and Hotel, used as training quarters for some of the greatest fighters in boxing history from 1883 to 1914. James J. Corbett, Bob Fitzsimmons, Jim Jeffries, Jack Johnson, and several other champions all stayed and trained here. Today, this preserved building has been adapted for retail and restaurants. Neptune Court, a block away on the corner of Central and McKay avenues, is also a surviving building from the resort era. The vast majority of the Neptune Beach structures – the hand-carved carousel from the world-famed Dentzel Company, the Ferris wheel, the roller coaster, and other rides – were auctioned off in 1940, yielding pennies on the dollar of their original cost. The city did not construct any swimming facilities or develop a local beach to replace that of Neptune Beach. Transportation When the railroad came to town in 1860s, Park Street developed as the major thoroughfare of the city. After the main Alameda train station was located here, residents of Old Alameda pulled up stakes and moved across town to the new downtown. The street's location was chosen by two landowners who wished to attract tenants and development to their land. They designated their mutual property line as Park Street. The need for expanded shipping facilities and increased flow of current through the estuary led to the dredging of a tidal canal through the marshland between Oakland and Alameda. Construction started in 1874, but it was not completed until 1902, resulting in Alameda becoming an island. Most of the soil from the canal dredging was used to fill in the nearby marshland. The area of Alameda called Bay Farm Island is no longer an island but is attached by fill to Oakland. In his youth, author Jack London was known to take part in oyster pirating in the highly productive oyster beds near Bay Farm Island, today long gone. The Alameda Works Shipyard was one of the largest and best-equipped shipyards in the country. Together with other industrial facilities, it became part of the defense industry buildup before and during World War II, which attracted many African-American and European-American migrants from other parts of the United States for the high-paying jobs. In the 1950s, Alameda's industrial and shipbuilding industries thrived along the Alameda Estuary. This was the site of operation of the world's first-ever, land-based, containerized shipping crane. In the early 21st century, the Port of Oakland, across the estuary, has become one of the largest ports on the West Coast. Its operators use shipping technologies originally experimented within Alameda. As of March 21, 2006, Alameda is a "Coast Guard City", one of seven then designated in the country. As of 2018, it is one of twenty-one within the country. In addition to the regular trains running to the Alameda Mole, Alameda was also served by local steam commuter lines of the Southern Pacific (initially, the Central Pacific). Alameda was the site of the Southern Pacific's West Alameda Shops, where all the electric trains were maintained and repaired. These were later adapted as the East Bay Electric Lines. Southern Pacific's electrified trains were not streetcars, but full-sized railroad cars that connected to the mainland via bridges at Webster Street and Fruitvale (only the latter bridge survives today). The trains ran to both the Oakland Mole and the Alameda Mole. A line that ran between the two moles was dubbed the "Horseshoe Line" for the shape of the route on a map. Soon after completion of the Bay Bridge, Alameda trains connected directly to San Francisco by the lower deck of the bridge. The ferries became unnecessary. In the 1930s Pan American Airways established a seaplane port along with the fill that led to the Alameda Mole. This was the original home base for the China Clipper flying boat. In 1929, the University of California established the San Francisco Airdrome located near the current Webster Street tube as a public airport. The Bay Airdrome had its gala christening party in 1930. The airfield was a busy place, as an early home base for Coastal Air Freight, Varney Air Lines, West Coast Air Transport, Western Air Express, the Transbay Air Ferries, and Boeing's Pacific Air Transport. The Airdrome was closed in 1941 when its air traffic interfered with the newly built Naval Air Station Alameda (NAS Alameda). With the advent of World War II, a vast stretch of the marshy area southwest of the Alameda Mole was filled and the NAS Alameda established. This major Naval facility included a large airfield, as well as docks for several aircraft carriers. It closed in 1997. Starting in the 1940s and continuing into the 1970s, multiple proposals were considered to build a highway bridge from Alameda to the San Francisco Peninsula, known as the Southern Crossing. The Bay Area Rapid Transit is currently studying the creation of a second Transbay Tube; some potential alignments would bring BART service to Alameda Island. 1950–present In the late 1950s, the Utah Construction Company began a landfill beyond the Old Sea Wall and created South Shore. On February 7, 1973, a USN Vought A-7E Corsair II fighter jet on a routine training mission from Lemoore Naval Air Station suddenly caught fire above the San Francisco Bay, crashing into the Tahoe Apartments in Alameda. Eleven people, including pilot Lieutenant Robert Lee Ward, died in the crash and fire. Geography Alameda's nickname is "The Island City" (or simply "the island"). The current city occupies three islands as well as a small section of the mainland. Today, the city consists of the main original section, with the former Naval Air Station Alameda (NAS Alameda) at the west end of Alameda Island, Southshore along the southern side of Alameda Island, and Bay Farm Island, which is part of the mainland proper. The area of the former NAS is now known as "Alameda Point." The Southshore area is separated from the main part of Alameda Island by a lagoon; the north shore of the lagoon is located approximately where the original south shore of the island was. Alameda Point and Southshore are built on bay fill. Not all of Alameda Island is part of the City of Alameda; a small portion of a dump site west of the former runway at Alameda Naval Air Station extends far enough into San Francisco Bay that it is over the county line and therefore part of the City and County of San Francisco. Coast Guard Island, a small island between Alameda Island and Oakland, is also part of Alameda and is the home of Integrated Support Command Alameda. Ballena Isle, an even smaller island, is also part of Alameda. Climate This region experiences warm (but not hot), dry summers, and cool (but not cold), wet winters. According to the Köppen climate classification system, Alameda has a warm-summer Mediterranean climate, abbreviated "Csb" on climate maps. Annual precipitation is about , all rain (snow is extremely rare at sea level in the San Francisco Bay Area).

Transportation Vehicle access to Alameda Island is via three bridges from Oakland (Park Street, Fruitvale Avenue, and High Street Bridges), as well as the two one-way Posey and Webster Street Tubes leading into Oakland's Chinatown. Connections from Alameda to Bay Farm Island are provided via the Bay Farm Island Bridge for vehicular traffic as well as the Bay Farm Island Bicycle Bridge (the only pedestrian/bicycle-only drawbridge in the United States). California State Route 61 runs down city streets from the Posey and Webster Street Tubes, across the Bay Farm Island Bridge, and south to the Oakland Airport. The island is just minutes off Interstate 880 in Oakland. The speed limit for the city is 25 mph (40 km/h) on almost every road. Public transportation options include: AC Transit buses, which range from local connections to Oakland and Berkeley to express service to San Francisco Ferry services – In addition to the Alameda/Oakland Ferry and the Alameda Harbor Bay Ferry routes, San Francisco Bay Ferry also provides service between Alameda Main Street Station and South San Francisco. All ferry services are operated by the Water Transit Authority. The closest BART stations are Lake Merritt and 12th Street, near the exit to the Posey Tube, and Fruitvale, near the Fruitvale Bridge. BART's long-term plans for a second tunnel include Alameda as a candidate for the first stop on a new East Bay line. Attractions Victorian houses comprise 9% of all single-family houses (1,500) in Alameda and many more have been divided into two- to four-unit dwellings. With its proximity to the Bay, wind surfers and kite surfers can often be seen at Robert W. Crown Memorial State Beach. From the beach, there are also views of the San Francisco skyline and the San Francisco–Oakland Bay Bridge. The aircraft carrier , a museum ship, has been moored at the former Naval Air Station as the USS Hornet Museum since 1998. This ship was originally named the USS Kearsarge, but was renamed in honor of the previous Hornet (CV-8) (famous for the Doolittle raid), which was lost in October 1942. Alameda was twice home to the official offices and training facility of the National Football League Oakland Raiders. First from 1966 until 1983 when the team moved to Los Angeles and the offices and training facility moved to El Segundo, California, and again from 1996 until 2020 when the team moved to Las Vegas and the offices and training facility moved to Henderson, Nevada. The Oakland Roots of the USL Championship have a license agreement for the former Raiders performance center with the City of Oakland and the County of Alameda. At the turn of the 19th century, the city of Alameda took a large chunk of Charles Froling's land away to build a street. Froling had planned to build his dream house on the plot of land he received through inheritance. To spite the city and an unsympathetic neighbor, Froling built a house wide, long and high on the tiny strip of land left to him. The Froling spite house is still standing and occupied. The Fourth of July parade is advertised as the second oldest and second-longest Fourth of July parade in the United States. It features homemade floats, classic cars, motorized living room furniture, fire-breathing dragons, and marching bands. The Historic Park Street Business District has many buildings that date back to the 1800s and is a designated Historic Commercial District on the National Register. This main thoroughfare of downtown Alameda Is filled with local shops, restaurants, drinking establishments, and services. The renovated 1932 Alameda Theatre & Cineplex is the cultural centerpiece of the commercial district. Economy Top employers According to the city's 2020 Comprehensive Annual Financial Report, the top employers in the city are: Alameda Point Naval Air Station Alameda (NAS) which was decommissioned in 1997, has been turned over to the City of Alameda for civilian development. America's Cup The 33rd America's Cup Race was won by Golden Gate Yacht Club racing team BMW Oracle, founded by Larry Ellison. Possible use of the air station that was considered was to partner with San Francisco for 34th America's Cup. Within two weeks of the Golden Gate Yacht Club winning the America's Cup, Alameda city council with local support sent a unanimous letter of support to hold AC 34 in San Francisco Bay Area. In early 2011, the City Council created an ad hoc America's Cup Citizens Advisory Committee to look for ways that Alameda could draw interest from teams and potential spectators. Through these efforts, the Swedish Artemis Racing team created their team based in one of the former air station hangars on Alameda Point, with a dock at Seaplane Lagoon. Beer, wine and spirits production A cluster of artisan distilleries, wineries, breweries and tasting rooms along Monarch Street at Alameda Point is now referred to by the City of Alameda as "Spirits Alley". These business include Rock Wall Winery, Building 43 Winery, Hangar 1, St. George Spirits and Faction Brewing. In 2017, Admiral Maltings opened at Alameda Point. Designed to supply craft brewers and whisky producers, it is the first craft malting house in California. The modern era of winemaking in Alameda begins in 1978 when Alameda veterinarian Kent Rosenblum and his wife Kathy founded Rosenblum Cellars. In 2008, the company was purchased by Diageo Estates for $105 million. In 2014, the Rosenblum tasting room at Alameda Point closed and moved to Jack London Square in Oakland. Shauna Rosenblum, daughter of Kent and Kathy, is the winemaker for Rock Wall Winery. In December 2007, St. George Absinthe Verte, produced by St. George Spirits became the first brand of American-made absinthe to be legally produced in the United States since a ban was enacted in 1912. Alameda Island Brewing is located on Park Street. Media Alameda's first newspaper, the Encinal, appeared in the early 1850s and the paper's editor was instrumental in the movement to incorporate the city. Following the Encinal, several other papers appeared along geographic lines, and the Daily Argus eventually rose to prominence. A young Alameda native, Joseph R. Knowland, wrote political and historical articles for the Alameda papers. Later, Knowland owned the powerful Oakland Tribune. Around 1900, the Daily Argus began to fade in importance and east and west papers The Times and The Star combined to take the leading role as the Alameda Times-Star in the 1930s. The Times-Star was sold to the Alameda Newspaper Group in the 1970s. In 1997, the Hills Newspaper chain was bought by Knight Ridder, at the time, the second-largest newspaper chain in the U.S. Following the buyout, former Hills Newspapers employees recognized the lack of a local community voice in Alameda, and again formed a new locally based newspaper, the Alameda Sun, in 2001. In 2006, Knight Ridder announced its impending sale to McClatchy Corp., a Sacramento-based publishing firm. McClatchy Corp. has put the Contra Costa Times, which under the Knight-Ridder reorganization included all five of the original Hills Newspapers, up for sale. The current owners of the Alameda Times-Star, Digital First Media, based in Colorado, have announced a strong interest in buying both the Contra Costa Times chain and the San Jose Mercury News, consolidating the daily newspaper market of the East Bay, effectively under one owner. MediaNews closed the Times-Star in 2011. The Alameda community is currently served by two weekly newspapers, the Alameda Journal, owned by the Digital First Media, and the Alameda Sun. Services Alameda Free Library After two previous failures, voters in the city passed a ballot measure in 2000 authorizing a bond measure for construction of a new main library to replace the city's Carnegie Library, damaged during the 1989 Loma Prieta earthquake. The city also received state funds for the new main library and opened the doors to the new facility in November 2006. There are three library locations: the Main Library in downtown Alameda and two library branches; the Bay Farm Island Library serving the Bay Farm and Harbor Bay communities and the West End Library serving the West End of Alameda. Alameda Hospital Founded in 1894, Alameda Hospital is located at Clinton Avenue and Willow Street. Alameda Municipal Power Unlike surrounding communities, Alameda has a municipal power service, Alameda Municipal Power (AMP), that delivers services directly to consumers. AMP sold the majority of its telecommunications business to Comcast in 2008 but continues to provide telecommunication service at Alameda Point. During the California electricity crisis of 2000 and 2001, Alameda Municipal Power did not raise electricity rates, while residents in most of the state endured significant price increases. Arts and culture The Alameda Arts Council (AAC) serves as the local Alameda City arts council. The Alameda Civic Ballet is the ballet troupe of the city. The Alameda Museum features displays on the history of Alameda. The Alameda Art Association has about 80 members as of January 2011, and has a gallery space at South Shore Center mall. The Association began in 1944. An annual benefit, Circus for Arts in the Schools, was started by clown artist Jeff Raz in 2004. Photo-realist Robert Bechtle has painted numerous Alameda subjects, including Alameda Gran Torino, which was acquired by SFMOMA in 1974 and remains one of Bechtle's most famous works. Filming location Alameda has been home to many movie sets. Some of the movies filmed on the island have included Bicentennial Man, The Net, The Matrix Reloaded, The Matrix Revolutions, Bee Season, the original 1968 Your, Mine and Ours and the movie musical Rent. Parts of Alameda High School were animated for the Animatrix episode "Kid's Story". A massive hangar at the former Naval Air Station Alameda was used to film special scenes requiring computer-generated imagery for movies such as Bicentennial Man, Flubber, What Dreams May Come, Mission: Impossible 2 and many scenes from the Matrix trilogy, including the signature bullet time scene. The open space of the decommissioned naval base often hosts MythBusters''' more dangerous experiments. The movie "Spirit Of '76" was filmed all throughout Alameda. The documentary Shallow Waters: The Public Death of Raymond Zack was filmed at Alameda locations, and chronicled the 2011 death of Raymond Zack on Crown Beach in Alameda. The film was screened in 2016 at the Michaan Auction House Theater in Alameda. The USS Hornet Museum, permanently moored at Alameda Point, has been the site for scenes used in major theatrical releases: Pearl Harbor (2001), XXX: State of the Union, Rescue Dawn, and The Master. In addition, the aircraft carrier has been used for television shows such as JAG, Carrier, Looking, The Great Escape, and the special military episode of Fear Factor; plus a number of television commercials. Theaters The city restored the historic Art Deco city landmark Alameda Theatre, expanding it to include a theater multiplex. The public opening was May 21, 2008. The Altarena Playhouse, which performs comedies, dramas, and musicals, was founded in 1938 and is the longest continuously operating community theater in the San Francisco Bay Area. Festivals on Webster Street Webster Street in Alameda has long been the host of many arts, crafts and holiday festivals. During some of these festivals, the Chamber of Commerce along with the West Alameda Business Association (WABA) will block off a portion of Webster St. for the entertainment of festival-goers. Festivals such as The Island JAM bring a lot of local and outside visitors. Other events on the "West End" include Trick-or-Treat on Webster Street where merchants supply goodies for local children and culminate with a parade and costume contest; in December "Santa Claus Meet-n-Greet on Webster Street" happens with elves, and a photo with Santa Claus. Festivals on Park Street There are three major events when the street in Alameda's historic downtown district is closed to vehicular traffic. The Park Street Spring Festival takes place every May during the weekend of Mother's Day and attracts over 50,000 visitors. The Park Street Art & Wine Faire takes place the last weekend of every July and attracts over 100,000 visitors. Both street fairs feature over 150 arts & crafts vendors, food vendors, beer and wine pouring, a children's area, and two stages with regional entertainment. The Park Street Classic Car Show is held on the second Saturday every October and displays over 400 vintage vehicles. Sand Castle and Sculpture Contest The annual Sand Castle and Sculpture Contest takes place in June at the Robert Crown Memorial State Beach. The first contest was held in 1967.

Education Public primary and secondary education in Alameda is the responsibility of the Alameda Unified School District, which is legally separate from the City of Alameda government (as is common throughout California). The College of Alameda, a two-year community college in the West End is part of the Peralta Community College District. The city has numerous private primary schools, and one private high school, St. Joseph Notre Dame High School, a Catholic school. Sister cities Alameda's relationships with Wuxi and Jiangyin were initiated in 2005, in part, by Stewart Chen, who then served on the City of Alameda Social Service and Human Relations board, and who went on to be elected to Alameda City Council in November 2012. Wuxi, China, is a so-called friendship city, because the diplomacy organization Sister Cities International does not recognize the relationship. Jiangyin, China Arita, Japan Yeongdong-gun, South Korea Lidingö, Sweden. Initiated in 1959 as part of President Eisenhower's people-to-people-movement, whose purpose was to develop better understanding among people from different countries after World War II. Both Alameda and Lidingö are islands with a bridge connecting them to a big city. Dumaguete City of Negros Oriental, Philippines Friendship city Wuxi, China (Friendship city since 2004) Controversy In September 2013, a Tibetan rights group initiated a social media and e-mail campaign targeting the Mayor of Alameda, complaining that City of Alameda's participation in, and association with, a flag-raising ceremony to recognize National Day of the People's Republic of China on October 1 was tantamount to endorsing the communist regime in China, its human rights abuses, and the occupation of Tibet. The City of Alameda responded that the ceremony was a function of the Alameda Sister City Association and the Alameda Wuxi Friendship Committee, not a function of the City of Alameda. The Tibetan rights group responded that on September 26, the City of Alameda Social Service and Human Relations board appointed a member, Michael Robles-Wong, as a representative to the Sister City Association. On October 1, 2013, the Tibetan rights groupsTibetTruth and Bay Area Friends of Tibet sent roughly 75 protesters to Alameda City Hall to protest the ceremony, which organizers ultimately canceled before it began. Former City of Alameda Councilmember Frank Matarrese announced the cancellation. Then-city councilmember Stewart Chen subsequently defended the ceremony, as a diplomatic, not political, exercise.

Saints Vitalis and Agricola

Saints Vitalis and Agricola () are venerated as martyrs, who are considered to have died at Bologna about 304, during the persecution ordered by Roman Emperor Diocletian. Legend Agricola was a Christian citizen of Bologna who converted his slave, Vitalis, to Christianity; they became deeply attached to each other. Vitalis was first to suffer martyrdom, being executed in the amphitheatre. The authorities then tortured Agricola, but failed to make him give up his religion. He was finally crucified. Veneration Information about Vitalis and Agricola is based on the writings of Saint Ambrose. In 392 or 393, Eusebius, bishop of Bologna, had announced the discovery of the relics of Vitalis and Agricola in a Jewish cemetery in the city. He reburied the relics according to Christian rites, an event at which Ambrose attended. The reburial led to popular veneration of these saints. The cult of these two martyrs was diffused in Western Europe due to the efforts of Ambrose, who transferred some of the relics to Milan and gave some to Florence. He took some of the blood, parts of the cross, and the nails to Florence, placing these relics in the church erected by a woman named Juliana. On this occasion he delivered an oration in praise of virginity, with special reference to the three virgin daughters of Juliana. His mention of the martyrs Agricola and Vitalis in the first part of the oration is the only source of information on these martyrs' lives ("De exhortatione virginitatis", cc. i-u, in P.L., XVI, 335). In 396 other relics were sent to St. Victricus, Bishop of Rouen, and about the same date to St. Paulinus of Nola and others. The cult had as its center the city of Bologna, where a basilica was built to hold the relics. The Bolognese church of San Vitale ed Agricola in Arena, is purported to have been built over the remains of a Roman amphitheatre where the martyrdom of Vitalis and Agricola took place in the 4th century. The crypt of the two martyrs dates back to the 11th century.

Alpha helix

The alpha helix (α-helix) is a common motif in the secondary structure of proteins and is a right hand-helix conformation in which every backbone N−H group hydrogen bonds to the backbone C=O group of the amino acid located four residues earlier along the protein sequence. The alpha helix is also called a classic Pauling–Corey–Branson α-helix. The name 3.613-helix is also used for this type of helix, denoting the average number of residues per helical turn, with 13 atoms being involved in the ring formed by the hydrogen bond. Among types of local structure in proteins, the α-helix is the most extreme and the most predictable from sequence, as well as the most prevalent. Discovery In the early 1930s, William Astbury showed that there were drastic changes in the X-ray fiber diffraction of moist wool or hair fibers upon significant stretching. The data suggested that the unstretched fibers had a coiled molecular structure with a characteristic repeat of ≈. Astbury initially proposed a linked-chain structure for the fibers. He later joined other researchers (notably the American chemist Maurice Huggins) in proposing that: the unstretched protein molecules formed a helix (which he called the α-form) the stretching caused the helix to uncoil, forming an extended state (which he called the β-form). Although incorrect in their details, Astbury's models of these forms were correct in essence and correspond to modern elements of secondary structure, the α-helix and the β-strand (Astbury's nomenclature was kept), which were developed by Linus Pauling, Robert Corey and Herman Branson in 1951 (see below); that paper showed both right- and left-handed helices, although in 1960 the crystal structure of myoglobin showed that the right-handed form is the common one. Hans Neurath was the first to show that Astbury's models could not be correct in detail, because they involved clashes of atoms. Neurath's paper and Astbury's data inspired H. S. Taylor, Maurice Huggins and Bragg and collaborators to propose models of keratin that somewhat resemble the modern α-helix. Two key developments in the modeling of the modern α-helix were: the correct bond geometry, thanks to the crystal structure determinations of amino acids and peptides and Pauling's prediction of planar peptide bonds; and his relinquishing of the assumption of an integral number of residues per turn of the helix. The pivotal moment came in the early spring of 1948, when Pauling caught a cold and went to bed. Being bored, he drew a polypeptide chain of roughly correct dimensions on a strip of paper and folded it into a helix, being careful to maintain the planar peptide bonds. After a few attempts, he produced a model with physically plausible hydrogen bonds. Pauling then worked with Corey and Branson to confirm his model before publication. In 1954, Pauling was awarded his first Nobel Prize "for his research into the nature of the chemical bond and its application to the elucidation of the structure of complex substances" (such as proteins), prominently including the structure of the α-helix. Structure Geometry and hydrogen bonding The amino acids in an α-helix are arranged in a right-handed helical structure where each amino acid residue corresponds to a 100° turn in the helix (i.e., the helix has 3.6 residues per turn), and a translation of along the helical axis. Dunitz describes how Pauling's first article on the theme in fact shows a left-handed helix, the enantiomer of the true structure. Short pieces of left-handed helix sometimes occur with a large content of achiral glycine amino acids, but are unfavorable for the other normal, biological -amino acids. The pitch of the alpha-helix (the vertical distance between consecutive turns of the helix) is , which is the product of 1.5 and 3.6. What is most important is that the N-H group of an amino acid forms a hydrogen bond with the C=O group of the amino acid four residues earlier; this repeated i + 4 → i hydrogen bonding is the most prominent characteristic of an α-helix. Official international nomenclature specifies two ways of defining α-helices, rule 6.2 in terms of repeating φ, ψ torsion angles (see below) and rule 6.3 in terms of the combined pattern of pitch and hydrogen bonding. The α-helices can be identified in protein structure using several computational methods, one of which is DSSP (Define Secondary Structure of Protein). Similar structures include the 310 helix (i + 3 → i hydrogen bonding) and the π-helix (i + 5 → i hydrogen bonding). The α-helix can be described as a 3.613 helix, since the i + 4 spacing adds three more atoms to the H-bonded loop compared to the tighter 310 helix, and on average, 3.6 amino acids are involved in one ring of α-helix. The subscripts refer to the number of atoms (including the hydrogen) in the closed loop formed by the hydrogen bond. Residues in α-helices typically adopt backbone (φ, ψ) dihedral angles around (−60°, −45°), as shown in the image at right. In more general terms, they adopt dihedral angles such that the ψ dihedral angle of one residue and the φ dihedral angle of the next residue sum to roughly −105°. As a consequence, α-helical dihedral angles, in general, fall on a diagonal stripe on the Ramachandran diagram (of slope −1), ranging from (−90°, −15°) to (−35°, −70°). For comparison, the sum of the dihedral angles for a 310 helix is roughly −75°, whereas that for the π-helix is roughly −130°. The general formula for the rotation angle Ω per residue of any polypeptide helix with trans isomers is given by the equation The α-helix is tightly packed; there is almost no free space within the helix. The amino-acid side-chains are on the outside of the helix, and point roughly "downward" (i.e., toward the N-terminus), like the branches of an evergreen tree (Christmas tree effect). This directionality is sometimes used in preliminary, low-resolution electron-density maps to determine the direction of the protein backbone. Stability Helices observed in proteins can range from four to over forty residues long, but a typical helix contains about ten amino acids (about three turns). In general, short polypeptides do not exhibit much α-helical structure in solution, since the entropic cost associated with the folding of the polypeptide chain is not compensated for by a sufficient amount of stabilizing interactions. In general, the backbone hydrogen bonds of α-helices are considered slightly weaker than those found in β-sheets, and are readily attacked by the ambient water molecules. However, in more hydrophobic environments such as the plasma membrane, or in the presence of co-solvents such as trifluoroethanol (TFE), or isolated from solvent in the gas phase, oligopeptides readily adopt stable α-helical structure. Furthermore, crosslinks can be incorporated into peptides to conformationally stabilize helical folds. Crosslinks stabilize the helical state by entropically destabilizing the unfolded state and by removing enthalpically stabilized "decoy" folds that compete with the fully helical state. It has been shown that α-helices are more stable, robust to mutations and designable than β-strands in natural proteins, and also in artificial designed proteins. Visualization The 3 most popular ways of visualizing the alpha-helical secondary structure of oligopeptide sequences are (1) a helical wheel, (2) a wenxiang diagram, and (3) a helical net. Each of these can be visualized with various software packages and web servers. To generate a small number of diagrams, Heliquest can be used for helical wheels, and NetWheels can be used for helical wheels and helical nets. To programmatically generate a large number of diagrams, helixvis can be used to draw helical wheels and wenxiang diagrams in the R and Python programming languages. Experimental determination Since the α-helix is defined by its hydrogen bonds and backbone conformation, the most detailed experimental evidence for α-helical structure comes from atomic-resolution X-ray crystallography such as the example shown at right. It is clear that all the backbone carbonyl oxygens point downward (toward the C-terminus) but splay out slightly, and the H-bonds are approximately parallel to the helix axis. Protein structures from NMR spectroscopy also show helices well, with characteristic observations of nuclear Overhauser effect (NOE) couplings between atoms on adjacent helical turns. In some cases, the individual hydrogen bonds can be observed directly as a small scalar coupling in NMR. There are several lower-resolution methods for assigning general helical structure. The NMR chemical shifts (in particular of the Cα, Cβ and C′) and residual dipolar couplings are often characteristic of helices. The far-UV (170–250 nm) circular dichroism spectrum of helices is also idiosyncratic, exhibiting a pronounced double minimum at around 208 and 222 nm. Infrared spectroscopy is rarely used, since the α-helical spectrum resembles that of a random coil (although these might be discerned by, e.g., hydrogen-deuterium exchange). Finally, cryo electron microscopy is now capable of discerning individual α-helices within a protein, although their assignment to residues is still an active area of research. Long homopolymers of amino acids often form helices if soluble. Such long, isolated helices can also be detected by other methods, such as dielectric relaxation, flow birefringence, and measurements of the diffusion constant. In stricter terms, these methods detect only the characteristic prolate (long cigar-like) hydrodynamic shape of a helix, or its large dipole moment. Amino-acid propensities Different amino-acid sequences have different propensities for forming α-helical structure. Methionine, alanine, leucine, glutamate, and lysine uncharged ("MALEK" in the amino-acid 1-letter codes) all have especially high helix-forming propensities, whereas proline and glycine have poor helix-forming propensities. Proline either breaks or kinks a helix, both because it cannot donate an amide hydrogen bond (having no amide hydrogen), and also because its sidechain interferes sterically with the backbone of the preceding turn inside a helix, this forces a bend of about 30° in the helix's axis. However, proline is often seen as the first residue of a helix, it is presumed due to its structural rigidity. At the other extreme, glycine also tends to disrupt helices because its high conformational flexibility makes it entropically expensive to adopt the relatively constrained α-helical structure. Table of standard amino acid alpha-helical propensities Estimated differences in free energy, Δ(ΔG), estimated in kcal/mol per residue in an α-helical configuration, relative to alanine arbitrarily set as zero. Higher numbers (more positive free energies) are less favoured. Significant deviations from these average numbers are possible, depending on the identities of the neighbouring residues. {| class="wikitable sortable" |+Differences in free energy per residue !rowspan=2| Amino acid !rowspan=2 class="unsortable"| 3-letter !rowspan=2 class="unsortable"| 1-letter !colspan=2| Helical penalty |- !kcal/mol !kJ/mol |- | Alanine | Ala | A | |- | Arginine | Arg | R | |- | Asparagine | Asn | N | |- | Aspartic acid | Asp | D | |- | Cysteine | Cys | C | |- | Glutamic acid | Glu | E | |- | Glutamine | Gln | Q | |- | Glycine | Gly | G | |- | Histidine | His | H | |- | Isoleucine | Ile | I | |- | Leucine | Leu | L | |- | Lysine | Lys | K | |- | Methionine | Met | M | |- | Phenylalanine | Phe | F | |- | Proline | Pro | P | |- | Serine | Ser | S | |- | Threonine | Thr | T | |- | Tryptophan | Trp | W | |- | Tyrosine | Tyr | Y | |- | Valine | Val | V | |} Dipole moment A helix has an overall dipole moment due to the aggregate effect of the individual microdipoles from the carbonyl groups of the peptide bond pointing along the helix axis. The effects of this macrodipole are a matter of some controversy. α-helices often occur with the N-terminal end bound by a negatively charged group, sometimes an amino acid side chain such as glutamate or aspartate, or sometimes a phosphate ion. Some regard the helix macrodipole as interacting electrostatically with such groups. Others feel that this is misleading and it is more realistic to say that the hydrogen bond potential of the free NH groups at the N-terminus of an α-helix can be satisfied by hydrogen bonding; this can also be regarded as set of interactions between local microdipoles such as . Coiled coils Coiled-coil α helices are highly stable forms in which two or more helices wrap around each other in a "supercoil" structure. Coiled coils contain a highly characteristic sequence motif known as a heptad repeat, in which the motif repeats itself every seven residues along the sequence (amino acid residues, not DNA base-pairs). The first and especially the fourth residues (known as the a and d positions) are almost always hydrophobic; the fourth residue is typically leucine this gives rise to the name of the structural motif called a leucine zipper, which is a type of coiled-coil. These hydrophobic residues pack together in the interior of the helix bundle. In general, the fifth and seventh residues (the e and g positions) have opposing charges and form a salt bridge stabilized by electrostatic interactions. Fibrous proteins such as keratin or the "stalks" of myosin or kinesin often adopt coiled-coil structures, as do several dimerizing proteins. A pair of coiled-coils a four-helix bundle is a very common structural motif in proteins. For example, it occurs in human growth hormone and several varieties of cytochrome. The Rop protein, which promotes plasmid replication in bacteria, is an interesting case in which a single polypeptide forms a coiled-coil and two monomers assemble to form a four-helix bundle. Facial arrangements The amino acids that make up a particular helix can be plotted on a helical wheel, a representation that illustrates the orientations of the constituent amino acids (see the article for leucine zipper for such a diagram). Often in globular proteins, as well as in specialized structures such as coiled-coils and leucine zippers, an α-helix will exhibit two "faces" one containing predominantly hydrophobic amino acids oriented toward the interior of the protein, in the hydrophobic core, and one containing predominantly polar amino acids oriented toward the solvent-exposed surface of the protein. Changes in binding orientation also occur for facially-organized oligopeptides. This pattern is especially common in antimicrobial peptides, and many models have been devised to describe how this relates to their function. Common to many of them is that the hydrophobic face of the antimicrobial peptide forms pores in the plasma membrane after associating with the fatty chains at the membrane core. Larger-scale assemblies Myoglobin and hemoglobin, the first two proteins whose structures were solved by X-ray crystallography, have very similar folds made up of about 70% α-helix, with the rest being non-repetitive regions, or "loops" that connect the helices. In classifying proteins by their dominant fold, the Structural Classification of Proteins database maintains a large category specifically for all-α proteins. Hemoglobin then has an even larger-scale quaternary structure, in which the functional oxygen-binding molecule is made up of four subunits. Functional roles DNA binding α-Helices have particular significance in DNA binding motifs, including helix-turn-helix motifs, leucine zipper motifs and zinc finger motifs. This is because of the convenient structural fact that the diameter of an α-helix is about including an average set of sidechains, about the same as the width of the major groove in B-form DNA, and also because coiled-coil (or leucine zipper) dimers of helices can readily position a pair of interaction surfaces to contact the sort of symmetrical repeat common in double-helical DNA. An example of both aspects is the transcription factor Max (see image at left), which uses a helical coiled coil to dimerize, positioning another pair of helices for interaction in two successive turns of the DNA major groove. Membrane spanning α-Helices are also the most common protein structure element that crosses biological membranes (transmembrane protein), it is presumed because the helical structure can satisfy all backbone hydrogen-bonds internally, leaving no polar groups exposed to the membrane if the sidechains are hydrophobic. Proteins are sometimes anchored by a single membrane-spanning helix, sometimes by a pair, and sometimes by a helix bundle, most classically consisting of seven helices arranged up-and-down in a ring such as for rhodopsins (see image at right) or for G protein–coupled receptors (GPCRs). The structural stability between pairs of α-Helical transmembrane domains rely on conserved membrane interhelical packing motifs, for example, the Glycine-xxx-Glycine (or small-xxx-small) motif. Mechanical properties α-Helices under axial tensile deformation, a characteristic loading condition that appears in many alpha-helix-rich filaments and tissues, results in a characteristic three-phase behavior of stiff-soft-stiff tangent modulus. Phase I corresponds to the small-deformation regime during which the helix is stretched homogeneously, followed by phase II, in which alpha-helical turns break mediated by the rupture of groups of H-bonds. Phase III is typically associated with large-deformation covalent bond stretching. Dynamical features Alpha-helices in proteins may have low-frequency accordion-like motion as observed by the Raman spectroscopy and analyzed via the quasi-continuum model. Helices not stabilized by tertiary interactions show dynamic behavior, which can be mainly attributed to helix fraying from the ends. Helix–coil transition Homopolymers of amino acids (such as polylysine) can adopt α-helical structure at low temperature that is "melted out" at high temperatures. This helix–coil transition was once thought to be analogous to protein denaturation. The statistical mechanics of this transition can be modeled using an elegant transfer matrix method, characterized by two parameters: the propensity to initiate a helix and the propensity to extend a helix. In art At least five artists have made explicit reference to the α-helix in their work: Julie Newdoll in painting and Julian Voss-Andreae, Bathsheba Grossman, Byron Rubin, and Mike Tyka in sculpture. San Francisco area artist Julie Newdoll, who holds a degree in Microbiology with a minor in art, has specialized in paintings inspired by microscopic images and molecules since 1990. Her painting "Rise of the Alpha Helix" (2003) features human figures arranged in an α helical arrangement. According to the artist, "the flowers reflect the various types of sidechains that each amino acid holds out to the world". This same metaphor is also echoed from the scientist's side: "β sheets do not show a stiff repetitious regularity but flow in graceful, twisting curves, and even the α-helix is regular more in the manner of a flower stem, whose branching nodes show the influence of environment, developmental history, and the evolution of each part to match its own idiosyncratic function." Julian Voss-Andreae is a German-born sculptor with degrees in experimental physics and sculpture. Since 2001 Voss-Andreae creates "protein sculptures" based on protein structure with the α-helix being one of his preferred objects. Voss-Andreae has made α-helix sculptures from diverse materials including bamboo and whole trees. A monument Voss-Andreae created in 2004 to celebrate the memory of Linus Pauling, the discoverer of the α-helix, is fashioned from a large steel beam rearranged in the structure of the α-helix. The , bright-red sculpture stands in front of Pauling's childhood home in Portland, Oregon. Ribbon diagrams of α-helices are a prominent element in the laser-etched crystal sculptures of protein structures created by artist Bathsheba Grossman, such as those of insulin, hemoglobin, and DNA polymerase. Byron Rubin is a former protein crystallographer now professional sculptor in metal of proteins, nucleic acids, and drug molecules many of which featuring α-helices, such as subtilisin, human growth hormone, and phospholipase A2. Mike Tyka is a computational biochemist at the University of Washington working with David Baker. Tyka has been making sculptures of protein molecules since 2010 from copper and steel, including ubiquitin and a potassium channel tetramer.

Accrington

Accrington is a town in the Hyndburn borough of Lancashire, England. It lies about east of Blackburn, west of Burnley, east of Preston, north of Manchester and is situated on the culverted River Hyndburn. Commonly abbreviated by locals to "Accy", the town has a population of 35,456 according to the 2011 census. Accrington is a former centre of the cotton and textile machinery industries. The town is famed for manufacturing the hardest and densest building bricks in the world, "The Accrington NORI" (iron), which were used in the construction of the Empire State Building and for the foundations of Blackpool Tower; famous for Accrington Stanley F.C. and the Haworth Art Gallery which holds Europe's largest collection of Tiffany glass. History Origin of the name The name Accrington appears to be Anglo-Saxon in origin. In the records it variously appears as Akarinton in 1194; Akerunton, Akerinton and Akerynton in 1258; Acrinton in 1292; Ackryngton in 1311 and Acryngton in 1324. The name may mean acorn farmstead from Anglo-Saxon æcern meaning acorn and tun meaning farmstead or village. The southern part of Accrington, the township of New Accrington, was formerly in the Forest of Blackburnshire and the presence of oak trees may be inferred from local place names like Broad Oak and Oak Hill. The products of oak trees were once an important food for swine and a farmstead may have been named for such produce. Anglo-Saxon Æcerntun might become Middle English Akerenton, Akerinton and the like. Also worth considering is that in the Lancashire dialect acorn was akran. There is no known Old English personal name from which the first element can be derived. But if the Frisian names Akkrum, Akkeringa and Dutch name Akkerghem, are derived from the personal name Akker there may be a corresponding Old English name from which Accrington may be derived. Early history Accrington covers two townships which were established in 1507 following disafforestation; those of Old Accrington and New Accrington which were merged in 1878 with the incorporation of the borough council. There have been settlements there since the medieval period, likely in the Grange Lane and Black Abbey area, and the King's Highway which passes above the town was at one time used by the kings and queens of England when they used the area for hunting when the Forest of Accrington was one of the four forests of the hundred of Blackburnshire. Robert de Lacy gave the manor of Accrington to the monks of Kirkstall in the 12th century. The monks built a grange there; removing the inhabitants to make room for it. The locals got their revenge by setting fire to the new building, destroying its contents and in the process killing the three lay brothers who occupied it. An area of the town is named 'Black Abbey', a possible reference to the murders. Regardless of whatever happened, Accrington did not remain under monastic control for long before reverting to the de Lacys. It is thought the monks of Kirkstall may have built a small chapel there during their tenure for the convenience of those in charge residing there and their tenants, but the records are uncertain. What is known is that there was a chapel in Accrington prior to 1553 where the vicar of Whalley was responsible for the maintenance of divine worship. However it did not have its own minister and it was served, when at all, by the curate of one of the adjacent chapels. In 1717 Accrington was served by the curate of Church, who preached there only once a month. St. James's Church was built in 1763, replacing the old chapel however it did not achieve parochial status until as late as 1870. Industrial Revolution Until around 1830, visitors considered Accrington to be just a "considerable village". The Industrial Revolution, however, resulted in large changes and Accrington's location on the confluence of a number of streams made it attractive to industry and a number of mills were built in the town in the mid-18th century. Further industrialisation then followed in the late-18th century and local landowners began building mansions in the area on the outskirts of the settlement where their mills were located while their employees lived in overcrowded unsanitary conditions in the centre. Industrialisation resulted in rapid population growth during the 19th century, as people moved from over North West England to Accrington, with the population increasing from 3,266 in 1811 to 10,376 in 1851 to 43,211 in 1901 to its peak in 1911 at 45,029. This fast population growth and slow response from the established church allowed non-conformism to flourish in the town. By the mid-19th century, there were Wesleyan, Primitive Methodist, United Free Methodist, Congregationalist, Baptist, Swedenborgian, Unitarian, Roman Catholic and Catholic Apostolic churches in the town. The Swedenborgian church was so grand that it was considered to be the ‘Cathedral' of that denomination. For many decades the textiles industry, the engineering industry and coal mining were the central activities of the town. Cotton mills and dye works provided work for the inhabitants, but often in very difficult conditions. There was a regular conflict with employers over wages and working conditions. On 24 April 1826 over 1,000 men and women, many armed, gathered at Whinney Hill in Clayton-le-Moors to listen to a speaker from where they marched on Sykes's Mill at Higher Grange Lane, near the site of the modern police station and magistrates' courts, and smashed over 60 looms. These riots spread from Accrington through Oswaldtwistle, Blackburn, Darwen, Rossendale, Bury and Chorley. In the end, after three days of riots 1,139 looms were destroyed, 4 rioters and 2 bystanders shot dead by the authorities in Rossendale and 41 rioters sentenced to death (all of whose sentences were commuted). In 1842 'plug riots' a general strike spread from town to town due to conditions in the town. In a population of 9,000 people as few as 100 were fully employed. From 15 August 1842 the situation boiled over and bands of men entered the mills which were running and stopped the machinery by knocking out the boiler plugs. This allowed the water and steam to escape shutting down the mill machinery. Thousands of strikers walked over the hills from one town to another to persuade people to join the strike in civil disturbances that lasted about a week. The strike was associated with the Chartist movement but eventually proved unsuccessful in its aims. In the early 1860s the Lancashire cotton famine badly affected Accrington, although less so than the wider area due to its more diverse economy, with as many as half of the town's mill employees out of work at one time. Conditions were such that a Local Board of Health was constituted in 1853 and the town itself incorporated in 1878 allowing the enforcement of local laws to improve the town. Accrington Pals One well-known association the town has is with the 'Accrington Pals', the nickname given to the smallest home town battalion of volunteers formed to fight in the First World War. The Pals battalions were a peculiarity of the 1914-18 war: Lord Kitchener, the Secretary of State for War, believed that it would help recruitment if friends and work-mates from the same town were able to join up and fight together. Strictly speaking, the 'Accrington Pals' battalion is properly known as the '11th East Lancashire Regiment': the nickname is a little misleading, since of the four 250-strong companies that made up the original battalion only one was composed of men from Accrington. The rest volunteered from other east Lancashire towns such as Burnley, Blackburn and Chorley. The Pals' first day of action, 1 July 1916, took place in Serre, near Montauban in the north of France. It was part of the 'Big Push' (later known as the Battle of the Somme) that was intended to force the German Army into a retreat from the Western Front, a line they had held since late 1914. The German defences in Serre were supposed to have been obliterated by sustained, heavy, British shelling during the preceding week; however, as the battalion advanced it met with fierce resistance. 235 men were killed and a further 350 wounded — more than half of the battalion — within half an hour. Similarly, desperate losses were suffered elsewhere on the front, in a disastrous day for the British Army (approximately 19,000 British soldiers were killed in a single day). Later in the year, the East Lancashire Regiment was rebuilt with new volunteers — in all, 865 Accrington men were killed during World War I. All of these names are recorded on a war memorial, an imposing white stone cenotaph, which stands in Oak Hill Park in the south of the town. The cenotaph also lists the names of 173 local fatalities from World War II. The trenches from which the Accrington Pals advanced on 1 July 1916 are still visible in John Copse west of the village of Serre, and there is a memorial there made of Accrington brick. After the war and until 1986, Accrington Corporation buses were painted in the regimental colours of red and blue with gold lining. The mudguards were painted black as a sign of mourning. The current Mayor of Accrington is Lance Sergeant Gary Archer of the Scots Guards. Demography The 2001 census gave the population of Accrington town as 35,200. The figure for the urban area was 71,220, increased from 70,442 in 1991. This total includes Accrington, Church, Clayton-le-Moors, Great Harwood and Oswaldtwistle. For comparison purposes that is approximately the same size as Aylesbury, Carlisle and Guildford urban areas. The 2011 census gave a population of 35,456 for the Accrington built-up area subdivision (which includes Huncoat, Baxenden and Rising Bridge in Rossendale) and a population of 125,000 for the wider Accrington/Rossendale Built-up area. The area in 2001 was listed as , whereas in 2011 it was . The borough of Hyndburn as a whole has a population of 80,734. This includes Accrington Urban Area and other outlying towns and villages such as; Altham, Rishton, part of Belthorn, and Knuzden and Whitebirk (considered suburbs of Blackburn). Economy Formerly cotton and textile machinery were important industries in the town. NORIs, a type of iron-hard engineering brick, were produced nearby in Huncoat which was closed in 2013, but later reopened in 2015. Mills and factories are Accrington's past but there a few factories and garages which now occupy the old buildings. Accrington power station was coal and refuse fired electricity generating station located in Argyle Street adjacent to the gasworks. It supplied electricity to Accrington, Haslingden and the Altham and Clayton-le-Moors areas between 1900 and 1958. Regeneration and investment The council has a regeneration plan in place, which will, according to the council, boost the local economy. The plan is to upgrade many old shops and to build a bus station. A memorial for the Accrington Pals may be built outside the town hall. The Hyndburn Borough Council plans to spend £10 million to refurbish the town centre, which includes: Upgrading all the shops in the town centre. Building a new bus station. Plans for the new bus station, which was later named 'George Slynn' in honour of the former Hyndburn Council leader, were put forward in January 2013 and approved in October 2014. The bus station was completed during and officially opened on 11 July 2016. The new station came under heavy criticism with traders of Accrington's Market and town hall, as it would see the old station discontinued, which was situated much closer and provided ease of access for regular customers. Half of Blackburn Road is being refurbished and is now being made into a more attractive shopping street, upgrading shops, adding more trees, and repaving the pavements. As of 2014, two new phases were being built: the first one called the Acorn Park, where new houses were being built with balconies and greener spaces, and Project Phoenix, which will also include new housing. Geography Accrington is a hill town located at between the Pennines and the West Pennine Moors, within a bowl and largely encircled by surrounding hills to rising to a height of in the case of Hameldon Hill to the east. The River Hyndburn or Accrington Brook flows through the centre of the town. Hill settlements origins were as the economic foci of the district engaging in the spinning and weaving of woollen cloth. Wool, lead and coal were other local industries. Geographical coordinates: 53° 46' 0" North, 2° 21' 0" West. Height above sea level: there is a spot height outside the Market Hall which is the benchmark on the side of the neighbouring Town Hall is . The highest height in the town is which is in Baxenden and the lowest at the town hall which is at . Transport The town has strong local travel links as Accrington railway station lies on the East Lancashire Line serving trains running locally and trains running from Blackpool to York. However, recent changes to the train timetables have been a disservice to Accrington, increasing the journey time to Preston (a vital link to London or Scotland) by up to 1.5 hours. However, there are still buses to Manchester every thirty minutes as well as more frequent services to other towns in East Lancashire. The main road running through the town centre is the A680 running from Rochdale to Whalley. The town is served by junction seven of the M65 and is linked from the A680 and the A56 dual carriageway which briefly merge; linking to the M66 motorway heading towards Manchester. The closest airports are Manchester Airport at , Blackpool Airport at and Leeds Bradford Airport at . There was once a rail link south to Manchester via Haslingden and Bury, but this was closed in the 1960s as part of cuts following the Beeching Report. The trackbed from Accrington to Baxenden is now a linear treelined cycleway/footpath. A train service to Manchester via the Todmorden Curve opened in 2015. A new bus station is being built in Accrington too. Bus operator Pilkington Bus are based in Accrington, and Holmeswood Coaches, Rosso and Transdev Blazefield subsidiaries Blackburn Bus Company and Burnley Bus Company also provide bus services in the town; routes serve places such as Blackburn, Oswaldtwistle, Rishton, Burnley and Clitheroe. However M&M Coaches ceased business suddenly on 21 September 2016 Public services Accrington Library, on St James Street, is a Carnegie library that opened in 1908. It is noted for its stained glass window designed by Gustav Hiller and as a place of inspiration for the young Jeanette Winterson. Near the Tesco supermarket, there is Accrington Skate Park which is popular during the school holidays. On Broadway, Accrington Police Station serves the Borough of Hyndburn. In April 2003, Hyndburn Community Fire Station opened, also serving the Borough of Hyndburn. Law enforcement The town is served by the Lancashire Constabulary Police station on Broadway after moving into town from its previous location on Manchester Road as an effort to save money due to rising expenses and decreasing funding by the government. Crime is very low in Accrington compared to nearby towns. Policing of the Railway station and railway-owned properties are served by the British Transport Police, nearest post in Preston. Social Governance Accrington is represented in parliament as a part of the constituency of Hyndburn. The constituency boundaries do not align exactly with those of the district of the same name. Accrington was first represented nationally after the Redistribution of Seats Act 1885 after the 1885 general election by Accrington (UK Parliament constituency). This seat was abolished in the 1983 general election and replaced with the present constituency of Hyndburn (UK Parliament constituency). Accrington became incorporated as a municipal borough in 1878. Under the Local Government Act 1972, since 1974, the town has formed part of the larger Borough of Hyndburn including the former Urban Districts of Oswaldtwistle, Church, Clayton-le-Moors, Great Harwood and Rishton. Hyndburn consists of 16 wards, electing a total of 35 councillors. Due to its size Accrington is represented by a number of wards in the Borough of Hyndburn. The town largely consists of the Milnshaw, Peel, Central, Barnfield and Spring Hill wards, although some parts of those wards are in other towns in the borough. Health The local hospital is Accrington Victoria Hospital however, as it only deals with minor issues, Accident and Emergency is provided by the Royal Blackburn Hospital. Other services are provided at the Accrington Pals Primary Health Care Centre and the Accrington Acorn Primary Health Care Centre. Media The chief publications in the area are the weekly Accrington Observer, part of MEN media, and the Lancashire Telegraph. Accrington Observer is currently stationed within the Market Hall. Special events A Ron Hill 10K marathon happens every year at the end of March or the start of April and is named for the local Olympic runner for Britain Ron Hill. The marathon goes around town and through the local countrysides and is organised by the council and local businesses. There is also an annual 1K family run which began in 2014. In 2015 more than five hundred runners ran in the race. Their also a race held by the local rotary around August time. Sport Football team Accrington Stanley F.C., entered the Football League in 1921 with the formation of the old Third Division (North); after haunting the lower reaches of English football for forty years, they eventually resigned from the League in 1962, due to financial problems, and folded in 1965. The club was reformed three years later and then worked its way through the non-league divisions to reach the Nationwide Conference in 2003. In the 2005–06 season, Stanley, after winning against Woking with three matches to spare, secured a place back in the Football League and the town celebrated with a small parade and honours placed on senior executives of the team. One of the teams relegated— and thus being replaced by Stanley—were Oxford United, who was voted into the Football League to replace the previous Accrington Stanley. The football stadium is called the Crown Ground. Until the 2012–13 season, when Fleetwood Town entered the league, Accrington was the smallest town in England and Wales with a Football League club. Accrington Stanley Football Club has had its own pub in the town, the Crown, since July 2007. Team history An earlier club, Accrington F.C., was one of the twelve founder members of the Football League in 1888. However, their time in league football was even less successful and considerably briefer than that of Accrington Stanley: they dropped out of the league in 1893 and folded shortly afterwards due to financial problems. The town of Accrington thus has the unique "distinction" of having lost two separate clubs from league football. They are currently placed in EFL League One after winning the EFL League Two title in the 2017/18 season. Cricket Accrington Cricket Club plays at Thorneyholme Road in the Lancashire League. Cricket is also played in parks. Schools nearby have shown major interest in cricket and have held cricket training and tournaments. Other sports There are many gyms in the town and the council has held fitness classes for the women and old people. There are two sports centres, the main one being the Hyndburn Sports Centre, which recently renovated its swimming pool area and is situated near Lidl. Education Accrington has the following primary schools: St Mary's RC Primary School, Clayton le Moors Hyndburn Park Primary School, Peel Park Primary School, Sacred Heart Primary School, Benjamin Hargreaves CE Primary School, Springhill County Primary School, Accrington Huncoat Primary School, St Johns and St Augustines CE Primary School, St Mary Magdalen's CE Primary School, St Nicholas' CE Primary School, Woodnook Primary School, St James CE Primary School, Altham, St Johns CE Primary School, Baxenden, All Saints CE Primary School, Mount Pleasant Primary School, Green Haworth CE Primary School, Stonefold CE Primary School, St Peters CE Primary School.

Landmarks Haworth Art Gallery The Haworth Art Gallery was previously a mansion named as Hollins Hill Mansion. The museum houses a collection of Tiffany glassware presented to the town by Joseph Briggs, an Accrington man who had joined Tiffany's in the late 19th century and eventually became art director and assistant manager. It is situated in Haworth Park on Manchester Road. The Viaduct The Viaduct is a bridge which has a railway line on it, it goes through the town and has many storage units and shop on sale by National Rail. The Viaduct ends at the Accrington Eco Station. Town Hall Accrington Town Hall was built in memory of Sir Robert Peel and opened as the Peel Institute in 1858; it is also listed. The Arcade The Arcade is a Victorian shopping Centre with about 10-15 outlets and has many restaurants there. It is on Church street near the town hall. The arcade has hardware shops and shops like Argos. There are some restaurants in there too. Sadly most outlets are closing since the year 2013. In 2016, there was a revamp of the Arcade which saw specialist shops such as Darts, Vinyl and Knitted Wear added into the Arcade. Oakhill Park Oakhill Park is a large and old park with a sceneric view of Accrington. It has won many awards such as the best park in Lancashire. It has also been awarded an Eco Award. The Haworth Art Gallery is in the park. It is on Manchester Road. The Coppice and Peel Park Peel Park is a park in Accrington which was opened by William Peel on 29 September 1909. The Coppice is a hill within the park, and provides a 2.2 mile scenic walk around the park. There was a centenary celebration marking 100 years from the Coppice being handed over to the people of Accrington on 26 September 2009. There was also a refurbishment of the paths and monument at the top of the Coppice at this time. Since then there has been several revamps to the Playground area of the park.

Armageddon

According to the Book of Revelation in the New Testament of the Christian Bible, Armageddon (, from Harmagedōn, Late Latin: , from Hebrew: Har Məgīddō) is the prophesied location of a gathering of armies for a battle during the end times, which is variously interpreted as either a literal or a symbolic location. The term is also used in a generic sense to refer to any end of the world scenario. In Islamic theology, the Armageddon is also mentioned in Hadith as the Greatest Armageddon or Al-Malhama Al-Kubra (the great battle). The "mount" of Megiddo in northern Israel is not actually a mountain, but a tell (a mound or hill created by many generations of people living and rebuilding on the same spot) on which ancient forts were built to guard the Via Maris, an ancient trade route linking Egypt with the northern empires of Syria, Anatolia and Mesopotamia. Megiddo was the location of various ancient battles, including one in the 15th century BC and one in 609 BC. The nearby modern Megiddo is a kibbutz in the Kishon River area. Etymology The word Armageddon appears only once in the Greek New Testament, in Revelation 16:16. The word is a Greek transliteration of the Hebrew har məgiddô (). Har means "a mountain or range of hills". This is a shortened form of harar meaning "to loom up; a mountain". Megiddo refers to a fortification made by King Ahab that dominated the Plain of Jezreel. Its name means "place of crowds". Christianity Megiddo is mentioned twelve times in the Old Testament, ten times in reference to the ancient city of Megiddo, and twice with reference to "the plain of Megiddo", most probably simply meaning "the plain next to the city". None of these Old Testament passages describes the city of Megiddo as being associated with any particular prophetic beliefs. The one New Testament reference to the city of Armageddon found in also makes no specific mention of any armies being predicted to one day gather in this city, but instead seems to predict only that "they (will gather) the kings together to... Armageddon". The text does however seem to imply, based on the text from the earlier passage of Revelation 16:14, that the purpose of this gathering of kings in the "place called Armageddon" is "for the war of the great day of God, the Almighty." Because of the seemingly highly symbolic and even cryptic language of this one New Testament passage, some Christian scholars conclude that Mount Armageddon must be an idealized location. R. J. Rushdoony says, "There are no mountains of Megiddo, only the Plains of Megiddo. This is a deliberate destruction of the vision of any literal reference to the place." Other scholars, including C. C. Torrey, Kline and Jordan argue that the word is derived from the Hebrew moed (), meaning "assembly".  Thus, "Armageddon" would mean "Mountain of Assembly," which Jordan says is "a reference to the assembly at Mount Sinai, and to its replacement, Mount Zion." Most traditions interpret this Bible prophecy to be symbolic of the progression of the world toward the "great day of God, the Almighty" in which God pours out his just and holy wrath against unrepentant sinners, led by Satan, in a literal end-of-the-world final confrontation. Armageddon is the symbolic name given to this event based on scripture references regarding divine obliteration of God's enemies. The hermeneutical method supports this position by referencing Judges 4 and 5 where God miraculously destroys the enemy of their elect, Israel, at Megiddo. Christian scholar William Hendriksen writes: Dispensationalism In his discussion of Armageddon, J. Dwight Pentecost has devoted a chapter to the subject, "The Campaign of Armageddon", in which he discusses it as a campaign and not a specific battle, which will be fought in the Middle East. Pentecost writes: Pentecost then discusses the location of this campaign, and mentions the "hill of Megiddo" and other geographic locations such as "the valley of Jehoshaphat" and "the valley of the passengers", "Lord coming from Edom or Idumea, south of Jerusalem, when he returns from the judgment"; and Jerusalem itself. Pentecost further describes the area involved: Pentecost then outlines the biblical time period for this campaign to occur and with further arguments concludes that it must take place with the 70th week of Daniel. The invasion of Israel by the Northern Confederacy "will bring the Beast and his armies to the defense of Israel as her protector". He then uses Daniel to further clarify his thinking. Again, events are listed by Pentecost in his book: "The movement of the campaign begins when the King of the South moves against the Beast–False Prophet coalition, which takes place 'at the time of the end.'" The King of the South gets in battle with the North King and the Northern Confederacy. Jerusalem is destroyed as a result of this attack, and, in turn, the armies of the Northern Confederacy are destroyed. "The full armies of the Beast move into Israel and shall conquer all that territory. Edom, Moab, and Ammon alone escape. . . ." ". . . a report that causes alarm is brought to the Beast" "The Beast moves his headquarters into the land of Israel and assembles his armies there." "It is there that his destruction will come." After the destruction of the Beast at the Second Coming of Jesus, the promised Kingdom is set up, in which Jesus and the saints will rule for a thousand years. Satan is then loosed "for a season" and goes out to deceive the nations, specifically, Gog and Magog. The army mentioned attacks the saints in the New Jerusalem, they are defeated by a judgment of fire coming down from heaven, and then comes the Great White Throne judgment, which includes all of those through the ages and these are cast into the Lake of Fire, which event is also known as the "second death" and Gehenna, not to be confused with Hell, which is Satan's domain. Pentecost describes this as follows: Jehovah's Witnesses Jehovah's Witnesses believe that Armageddon is the means by which God will fulfill his purpose for the Earth to be populated with happy healthy humans who will be free from sin and death. They teach that the armies of heaven will eradicate all who oppose the Kingdom of God, wiping out all wicked humans on Earth, only leaving righteous mankind. They believe that the gathering of all of the nations of the earth refers to the uniting of the world's political powers, as a gradual process which began in 1914 and was later seen in manifestations such as the League of Nations and the United Nations following the First and Second World Wars. These political powers are said to be influenced by Satan and his demons in opposition to God's kingdom. Babylon the Great is interpreted as being the world empire of false religions, and it will be destroyed by the beast just prior to Armageddon. Witnesses believe that after all other religions have been destroyed, the governments of the world will begin persecuting Witnesses, and God will then intervene, precipitating Armageddon. Jehovah's Witnesses teach that the armies of heaven, led by Jesus, will then destroy all forms of human government and then Jesus, along with a selected 144,000 humans, will rule Earth for 1,000 years. They believe that Satan and his demons will be bound for that period, unable to influence mankind. After the 1,000 years are ended, and the second resurrection has taken place, Satan is released and allowed to tempt the perfect human race one last time. Those who follow Satan will be destroyed, along with him, leaving the earth, and humankind at peace with God forever, free from sin and death. The religion's current teaching on Armageddon originated in 1925 with former Watch Tower Society president J. F. Rutherford, who based his interpretations on passages that are found in the books of Exodus, Jeremiah, Ezekiel and Psalms as well as additional passages that are found in the books of Samuel, Kings and Chronicles. The doctrine marked a further break from the teachings of the Watch Tower Society's founder Charles Taze Russell, who for decades had taught that the final war would be an anarchistic struggle for domination on earth. Tony Wills, the author of a historical study of Jehovah's Witnesses, wrote that Rutherford seemed to relish his descriptions of how completely the wicked would be destroyed at Armageddon, dwelling at great length on prophecies of destruction. He stated that towards the close of his ministry, Rutherford allocated about half the space that was available in The Watchtower magazines to discussions about Armageddon. Seventh-day Adventist The teachings of the Seventh-day Adventist Church state that the terms "Armageddon", "Day of the Lord" and "The Second Coming of Christ" all describe the same event. Seventh-day Adventists further teach that the current religious movements taking place in the world are setting the stage for Armageddon, and they are concerned by an anticipated unity between spiritualism, American Protestantism and Roman Catholicism. A further significant difference in Seventh-day Adventist theology is the teaching that the events of Armageddon will leave the earth desolate for the duration of the millennium. They teach that the righteous will be taken to heaven while the rest of humanity will be destroyed, leaving Satan with no one to tempt and effectively "bound." The final re-creation of a "new heaven and a new earth." then follows the millennium. Christadelphians For Christadelphians, Armageddon marks the "great climax of history when the nations would be gathered together 'into a place called in the Hebrew tongue Armageddon', and the judgment on them would herald the setting up of the Kingdom of God." Baháʼí Faith From Baháʼí literature, a number of interpretations of the expectations surrounding the Battle of Armageddon may be inferred, three of them being associated with events surrounding the World Wars. The first interpretation deals with a series of tablets written by Bahá'u'lláh, founder of the Baháʼí Faith, to be sent to various kings and rulers. The second, and best-known one, relates to events near the end of World War I involving General Allenby and the Battle of Megiddo (1918) wherein World Powers are said to have drawn soldiers from many parts of the world to engage in battle at Megiddo. In winning this battle Allenby also prevented the Ottomans from killing 'Abdu'l-Baha, then head of the Baháʼí Faith, whom they had intended to crucify. A third interpretation reviews the overall progress of the World Wars, and the situation in the world before and after.

Athlon

Athlon is the brand name applied to a series of x86-compatible microprocessors designed and manufactured by Advanced Micro Devices (AMD). The original Athlon (now called Athlon Classic) was the first seventh-generation x86 processor and was the first desktop processor to reach speeds of one gigahertz (GHz). It made its debut as AMD's high-end processor brand on June 23, 1999. Over the years AMD has used the Athlon name with the 64-bit Athlon 64 architecture, the Athlon II, and Accelerated Processing Unit (APU) chips targeting the Socket AM1 desktop SoC architecture, and Socket AM4 Zen microarchitecture. The modern Zen-based Athlon with a Radeon Graphics processor was introduced in 2019 as AMD's highest-performance entry-level processor. Athlon comes from the Ancient Greek (athlon) meaning "(sport) contest", or "prize of a contest", or "place of a contest; arena". With the Athlon name originally used for AMD's mid-range processors with combined CPU/GPU processors with the GPU disabled, AMD currently uses Athlon for budget APUs with integrated graphics. AMD positions the Athlon against its rival, the Intel Pentium. Brand history K7 design and development The first Athlon processor was a result of AMD's development of K7 processors in the 1990s. AMD founder and then-CEO Jerry Sanders aggressively pursued strategic partnerships and engineering talent in the late 1990s, working to build on earlier successes in the PC market with the AMD K6 processor line. One major partnership announced in 1998 paired AMD with semiconductor giant Motorola to co-develop copper-based semiconductor technology, resulting in the K7 project being the first commercial processor to utilize copper fabrication technology. In the announcement, Sanders referred to the partnership as creating a "virtual gorilla" that would enable AMD to compete with Intel on fabrication capacity while limiting AMD's financial outlay for new facilities. The K7 design team was led by Dirk Meyer, who had previously worked as a lead engineer at DEC on multiple Alpha microprocessors. When DEC was sold to Compaq in 1998 and discontinued Alpha processor development, Sanders brought most of the Alpha design team to the K7 project. This added to the previously acquired NexGen K6 team, which already included engineers such as Vinod Dham. Original release The AMD Athlon processor launched on June 23, 1999, with general availability by August 1999. Subsequently, from August 1999 until January 2002, this initial K7 processor was the fastest x86 chip in the world. Wrote the Los Angeles Times on October 5, 1999, "AMD has historically trailed Intel’s fastest processors, but has overtaken the industry leader with the new Athlon. Analysts say the Athlon, which will be used by Compaq Computer, IBM and other manufacturers in their most powerful PCs, is significantly faster than Intel’s flagship Pentium III, which runs at a top speed of 600MHz." A number of features helped the chips compete with Intel. By working with Motorola, AMD had been able to refine copper interconnect manufacturing about one year before Intel, with the revised process permitting 180-nanometer processor production. The accompanying die-shrink resulted in lower power consumption, permitting AMD to increase Athlon clock speeds to the 1 GHz range. The Athlon architecture also used the EV6 bus licensed from DEC as its main system bus, allowing AMD to develop its own products without needing to license Intel's GTL+ bus. By the summer of 2000, AMD was shipping Athlons at high volume and the chips were being used in systems by Gateway, Hewlett-Packard, and Fujitsu Siemens Computers among others. Later Athlon iterations The second generation Athlon, the Thunderbird, debuted in 2000. AMD released the Athlon XP the following year, and the Athlon XP's immediate successor, the Athlon 64, was an AMD64-architecture microprocessor released in 2003. While the Athlon name was originally used for combined CPU/GPU processors with the GPU disabled, after the 2007 launch of the Phenom processors, the Athlon name was also used for mid-range processors, positioned above brands such as Sempron. The Athlon 64 X2 was released in 2005 as the first native dual-core desktop CPU designed by AMD, and the Athlon X2 was a subsequent family based on the Athlon 64 X2. Introduced in 2009, Athlon II was a dual-core family of Athlon chips. A USD$55 low-power Athlon 200GE with a Radeon graphics processor was introduced in September 2018, sitting under the Ryzen 3 2200G. This iteration of Athlon used AMD's Zen-based Raven Ridge core, which in turn had debuted in Ryzen with Radeon graphics processors. With the release, AMD began using the Athlon brand name to refer to "low cost, high volume products," in a situation similar to both Intel's Celeron and Pentium Gold. The modern Athlon 3000G was introduced in 2019, and was positioned as AMD's highest-performance entry-level processor. AMD positions the Athlon against its rival, the Intel Pentium. While CPU processing performance is in the same ballpark, the Athlon 3000G uses Radeon Vega graphics, which are rated as more powerful than the Pentium's Intel UHD Graphics. Generations Athlon Classic (1999) The AMD Athlon processor launched on June 23, 1999, with general availability by August 1999. Subsequently, from August 1999 until January 2002, this initial K7 processor was the fastest x86 chip in the world. At launch it was, on average, 10% faster than the Pentium III at the same clock for business applications, and 20% faster for gaming workloads. In commercial terms, the Athlon "Classic" was an enormous success. Features The Athlon Classic is a cartridge-based processor, named Slot A and similar to Intel's cartridge Slot 1 used for Pentium II and Pentium III. It used the same, commonly available, physical 242 pin connector used by Intel Slot 1 processors but rotated by 180 degrees to connect the processor to the motherboard. The cartridge assembly allowed the use of higher speed cache memory modules than could be put on (or reasonably bundled with) motherboards at the time. Similar to the Pentium II and the Katmai-based Pentium III, the Athlon Classic contained 512 KB of L2 cache. This high-speed SRAM cache was run at a divisor of the processor clock and was accessed via its own 64-bit back-side bus, allowing the processor to service both front-side bus requests and cache accesses simultaneously, as compared to pushing everything through the front-side bus. The Argon-based Athlon contained 22 million transistors and measured 184 mm2. It was fabricated by AMD in a version of their CS44E process, a 0.25 μm complementary metal–oxide–semiconductor (CMOS) process with six levels of aluminium interconnect. "Pluto" and "Orion" Athlons were fabricated in a 0.18 μm process. The Athlon's CPU cache consisted of the typical two levels. Athlon was the first x86 processor with a 128 KB split level 1 cache; a 2-way associative cache separated into 2×64 KB for data and instructions (a concept from Harvard architecture). SRAM cache designs at the time were incapable of keeping up with the Athlon's clock scalability, resulting in compromised CPU clock speeds in some computers. With later Athlon models, AMD would integrate the L2 cache onto the processor itself, removing dependence on external cache chips. The Slot-A Athlons were the first multiplier-locked CPUs from AMD, preventing users from settting their own desired clock speed. This was done by AMD in part to hinder CPU remarking and overclocking by resellers, which could result in inconsistent performance. Eventually a product called the "Goldfingers device" was created that could unlock the CPU. AMD designed the CPU with more robust x86 instruction decoding capabilities than that of K6, to enhance its ability to keep more data in-flight at once. The critical branch predictor unit was enhanced compared to the K6. Deeper pipelining with more stages allowed higher clock speeds to be attained. Like the AMD K5 and K6, the Athlon dynamically buffered internal micro-instructions at runtime resulting from parallel x86 instruction decoding. The CPU is an out-of-order design, again like previous post-5x86 AMD CPUs. The Athlon utilizes the Alpha 21264's EV6 bus architecture with double data rate (DDR) technology. AMD ended its long-time handicap with floating point x87 performance by designing a super-pipelined, out-of-order, triple-issue floating point unit (FPU). Each of its three units could independently calculate an optimal type of instructions with some redundancy, making it possible to operate on more than one floating point instruction at once. This FPU was a huge step forward for AMD, helping compete with Intel's P6 FPU. The 3DNow! floating point SIMD technology, again present, received some revisions and was renamed "Enhanced 3DNow!" Additions included DSP instructions and the extended MMX subset of Intel SSE. Specifications L1-cache: 64 + 64 KB (data + instructions) L2-cache: 512 KB, external chips on CPU module with 50%, 40% or 33% of CPU speed MMX, 3DNow! Slot A (EV6) Front-side bus: 200 MT/s (100 MHz double-pumped) VCore: 1.6 V (K7), 1.6–1.8 V (K75) First release: June 23, 1999 (K7), November 29, 1999 (K75) Clock-rate: 500–700 MHz (K7), 550–1000 MHz (K75) Athlon Thunderbird (2000-2001) The second generation Athlon, the Thunderbird or T-Bird, debuted on June 4, 2000. This version of the Athlon had a traditional pin-grid array (PGA) format that plugged into a socket ("Socket A") on the motherboard or the slot A package. The major difference between it and the Athlon Classic was cache design, with AMD adding in 256 KB of on-chip, full-speed exclusive cache. In moving to an exclusive cache design, the L1 cache's contents were not duplicated in the L2, increasing total cache size and functionally creating a large L1 cache with a slower region (the L2) and a fast region (the L1), making the L2 cache into basically a victim cache. With the new cache design, need for high L2 performance and size was lessened, and the simpler L2 cache was less likely to cause clock scaling and yield issues. Thunderbird also moved to a 16-way associative layout. The Thunderbird was "cherished by many for its overclockability," and proved commercially successful, as AMD's most successful product since the Am386DX-40 ten years earlier. AMD's new fab facility in Dresden increased production for AMD overall and put out Thunderbirds at a fast rate, with the process technology improved by a switch to copper interconnects. After several versions were released in 2000 and 2001 of the Thunderbird, the last Athlon processor using the Thunderbird core was released in 2001 in the summer, at which point speeds were at 1.4 GHz. The locked multipliers of Socket A Thunderbirds could often be disabled through adding conductive bridges on the surface on the chip, a practice widely known as "the pencil trick". Specifications L1-cache: 64 + 64 KB (data + instructions) L2-cache: 256 KB, full speed MMX, 3DNow! Slot A & Socket A (EV6) Front-side bus: 100 MHz (Slot-A, B-models), 133 MHz (C-models) (200 MT/s, 266 MT/s) VCore: 1.70–1.75 V First release: June 5, 2000 Transistor count: 37 million Manufacturing Process: 0.18 μm/180 nm Clockrate: Slot A: 650–1000 MHz Socket A, 100 MHz FSB (B-models): 600–1400 MHz Socket A, 133 MHz FSB (C-models): 1000–1400 MHz Athlon XP (2001-2003) Overall, there are four main variants of the Athlon XP desktop CPU: the Palomino, the Thoroughbred, the Thorton, and the Barton. A number of mobile processors were also released, including the Corvette models, and the Dublin model among others. Palomino On May 14, 2001, AMD released the Athlon XP processor. It debuted as the Mobile Athlon 4, a mobile version codenamed Corvette with the desktop Athlon XP released in the fall.  The third-generation Athlon, code-named Palomino, came out on October 9, 2001 as the Athlon XP, with the suffix signifying extended performance and unofficially referencing Windows XP. Palomino's design used 180 nm fabrication process size. The Athlon XP was marketed using a performance rating (PR) system comparing it to the Thunderbird predecessor core. Among other changes, Palomino consumed 20% less power than the Thunderbird,  comparatively reducing heat output, and was roughly 10% faster than Thunderbird. Palomino also had enhanced K7's TLB architecture and included a hardware data prefetch mechanism to take better advantage of memory bandwidth. Palomino was the first K7 core to include the full SSE instruction set from the Intel Pentium III, as well as AMD's 3DNow! Professional. Palomino was also the first socketed Athlon officially supporting dual processing, with chips certified for that purpose branded as the Athlon MP (multi processing), which had different specifications. According to HardwareZone, it was possible to modify the Athlon XP to function as an MP. Specifications L1-cache: 64 + 64 KB (data + instructions) L2-cache: 256 KB, full speed MMX, 3DNow!, SSE Socket A (EV6) Front-side bus: 133 MHz (266 MT/s) VCore: 1.50 to 1.75 V Power consumption: 68 W First release: October 9, 2001 Clock-rate: Athlon 4: 850–1400 MHz Athlon XP: 1333–1733 MHz (1500+ to 2100+) Athlon MP: 1000–1733 MHz Thoroughbred The fourth-generation of Athlon was introduced with the Thoroughbred core, or T-Bred, on April 17, 2002. The Thoroughbred core marked AMD's first production 130 nm silicon, with smaller die size than its predecessor. There came to be two steppings (revisions) of this core commonly referred to as Tbred-A and Tbred-B. Introduced in June 2002, the initial A version was mostly a direct die shrink of the preceding Palomino core, but did not significantly increase clock speeds over the Palomino. A revised Thoroughbred core, Thoroughbred-B, added a ninth "metal layer" to the eight-layered Thoroughbred-A, offering improvement in headroom over the A and making it popular for overclocking. Specifications L1-cache: 64 + 64 KB (data + instructions) L2-cache: 256 KB, full speed MMX, 3DNow!, SSE Socket A (EV6) Front-side bus: 133/166 MHz (266/333 MT/s) VCore: 1.50–1.65 V First release: June 10, 2002 (A), August 21, 2002 (B) Clock-rate: Thoroughbred "A": 1400–1800 MHz (1600+ to 2200+) Thoroughbred "B": 1400–2250 MHz (1600+ to 2800+) 133 MHz FSB: 1400–2133 MHz (1600+ to 2600+) 166 MHz FSB: 2083–2250 MHz (2600+ to 2800+) Barton / Thorton Fifth-generation Athlon Barton-core processors were released in early 2003. While not operating at higher clock rates than Thoroughbred-core processors, they featured an increased L2 cache, and later models had an increased 200 MHz (400 MT/s) front side bus. The Thorton core, a blend of thoroughbred and Barton, was a later variant of the Barton with half of the L2 cache disabled. The Barton was used to officially introduce a higher 400 MT/s bus clock for the Socket A platform, which was used to gain some Barton models more efficiency. By this point with the Barton, the four-year-old Athlon EV6 bus architecture had scaled to its limit and required a redesign to exceed the performance of newer Intel processors. By 2003, the Pentium 4 had become more than competitive with AMD's processors, and Barton only saw a small performance increase over the Thoroughbred-B it derived from, insufficient to outperform the Pentium 4. The K7 derived Athlons such as Barton were replaced in September 2003 by the Athlon 64 family, which featured an on-chip memory controller and a new HyperTransport bus. Notably, the 2500+ Barton with 11x multiplier was effectively identical to the 3200+ part other than the FSB speed it was binned for meaning seamless overlocking was possible more often than not. Early Thortons could be restored to the full Barton specification with the enabling of the other half of the L2 cache from a slight CPU surface modification but the result was not always reliable. Specifications Barton (130 nm) L1-cache: 64 + 64 KB (data + instructions) L2-cache: 512 KB, full speed MMX, 3DNow!, SSE Socket A (EV6) Front-side bus: 166/200 MHz (333/400 MT/s) VCore: 1.65 V First release: February 10, 2003 Clockrate: 1833–2333 MHz (2500+ to 3200+) 133 MHz FSB: 1867–2133 MHz (2500+ to 2800+); uncommon 166 MHz FSB: 1833–2333 MHz (2500+ to 3200+) 200 MHz FSB: 2100, 2200 MHz (3000+, 3200+) Thorton (130 nm) L1-cache: 64 + 64 KB (Data + Instructions) L2-cache: 256 KB, full speed MMX, 3DNow!, SSE Socket A (EV6) Front-side bus: 133/166/200 MHz (266/333/400 MT/s) VCore: 1.50–1.65 V First release: September 2003 Clockrate: 1667–2200 MHz (2000+ to 3100+) 133 MHz FSB: 1600–2133 MHz (2000+ to 2600+) 166 MHz FSB: 2083 MHz (2600+) 200 MHz FSB: 2200 MHz (3100+) Mobile Athlon XP The Palomino core debuted in the mobile market before the PC market, where it was branded as Mobile Athlon 4 with the codename "Corvette". It distinctively used a ceramic interposer much like the Thunderbird instead of the organic pin grid array package used on all later Palomino processors. In November 2001, AMD released a 1.2 GHz Athlon 4 and a 950 MHz Duron. The Mobile Athlon 4 processors included the PowerNow! function, which controlled a laptop's "level of processor performance by dynamically adjusting its operating frequency and voltage according to the task at hand," thus extending "battery life by reducing processor power when it isn't needed by applications." Duron chips also included PowerNow! In 2002, AMD released a version of PowerNow! called Cool'n'Quiet, implemented on the Athlon XP but only adjusting clock speed frequency instead of voltage. In 2002 the Athlon XP-M (Mobile Athlon XP) replaced the Mobile Athlon 4 using the newer Thoroughbred core, with Barton cores for full-size notebooks. The Athlon XP-M was also offered in a compact microPGA socket 563 version. Mobile XPs were not multiplier-locked, making them popular with desktop overclockers. Athlon 64 (2003-2009) The immediate successor to the Athlon XP, the Athlon 64 is an AMD64-architecture microprocessor produced by AMD, released on September 23, 2003. A number of variations, all named after cities, were released with 90 nm architecture in 2004 and 2005. Versions released in 2007 and 2009 utilized 65 nm architecture. Athlon 64 X2 (2005-2009) The Athlon 64 X2 was released in 2005 as the first native dual-core desktop CPU designed by AMD using an Athlon 64. The Athlon X2 was a subsequent family of microprocessors based on the Athlon 64 X2. The original Brisbane Athlon X2 models used 65 nm architecture, and were released in 2007. Athlon II (2009-2012) Athlon II is a family of central processing units. Initially a dual-core version of the Athlon II, the K-10-based Regor was released in June 2009 with 45 nanometer architecture. This was followed by a single-core version, Sargas, followed by the quad-core Propus, the triple-core Rana in November 2009, and the Llano 32 nm version released in 2011. Zen-based Athlon (2018-present) The Zen-based Athlon with Radeon graphics processors was launched in September 2018 with the Athlon 200GE. Based on AMD's Raven Ridge core previously used in variants of the Ryzen 3 and Ryzen 5, the Athlon 200GE had half of the cores but left SMT enabled. It also kept the same 4 MiB L3 cache, but the L2 cache was halved to 1 MiB. In addition, the number of graphics compute units was limited to 3 in the Athlon 200GE, and the chip was multiplier-locked. Despite its limitations, the Athlon 200GE performed competitively against the 5000-series Intel Pentium-G, displaying similar CPU performance but an advantage in GPU performance. On November 19, 2019, AMD released the Athlon 3000G, with a higher 3.5 GHz core clock and 1100 MHz graphics clock compared to the Athlon 200GE also with two cores. The main functional difference between the 200GE was the Athlon 3000G's unlocked multiplier, allowing the latter to be overclocked on B450 and X470 motherboards. Specifications (see Zen desktop APUs for more details) Raven Ridge (14 nm), Picasso (12 nm) L1 Cache: 192 KiB (2x64 KiB +2x32 KiB) L2 Cache: 1 MiB (2x512 KiB) L3 Cache: 4 MiB Memory: Dual-Channel DDR4-2666, 64 GiB Max Socket AM4 TDP: 35W First release: September 6, 2018 CPU Clockrate: 3.2 to 3.5 GHz GPU Clockrate: 1000 to 1100 MHz Supercomputers A number of supercomputers have been built using Athlon chips, largely at universities. Among them: In 2000, several American students claimed to have built the world's least expensive supercomputer by clustering 64 AMD Athlon chips together, also marking the first time Athlons had been clustered in a supercomputer. The PRESTO III, a Beowulf cluster of 78 AMD Athlon processors, was built in 2001 by the Tokyo Institute of Technology. That year it ranked 439 on the Top 500 list of supercomputers. In 2002, a "128-Node 256-Processor AMD Athlon Supercomputer Cluster" was installed at the Ohio Supercomputer Center at the University of Toledo. Rutgers University, Department of Physics & Astronomy.

https://en.wikipedia.org/wiki/Amnon

Amnon

Amnon ( ’Amnōn, "faithful") was, in the Hebrew Bible, the oldest son of King David and his second wife, Ahinoam of Jezreel. He was born in Hebron during his father's reign in Judah. He was the heir apparent to the throne of Israel until he was assassinated by his half-brother Absalom to avenge the rape of Absalom's sister Tamar. Biblical account Amnon's background Amnon was born in Hebron to Ahinoam and King David. As the presumptive heir to the throne of Israel, Amnon enjoyed a life of power and privilege. Rape of Tamar Although he was the heir-apparent to David's throne, Amnon is best remembered for the rape of his half-sister Tamar, daughter of David and Maachah. Despite the biblical prohibition on sexual relations between half siblings, Amnon had an overwhelming desire for her. He acted on advice from his cousin, Jonadab son of Shimeah, David's brother, to lure Tamar into his quarters by pretending to be sick and desiring her to cook a special meal for him. While in his quarters, and over her protests, he raped her, then had her expelled from his house. While King David was angry about the incident, he could not bring himself to punish his eldest son, while Absalom, Amnon's half-brother and Tamar's full brother, nursed a bitter grudge against Amnon for the rape of his sister. According to the Babylon Talmud: "And Thou should not associate with a sinner:....And so we find with Amnon, who associated with Jonadab, the son of Shim'ah, David's brother; and Jonadab was a very sensible man--sensible in wickedness, as it is written [Jer. Iv .22]: Wise are they to do evil." According to others, it is meant that one shall not associate with the wicked,even to study the Torah." According to Rav, Tamar was not, by Biblical law, David's daughter, nor Amnon's sister. Tamar, was the earlier born daughter of David's wife, and thus not biologically related to David, nor Amnon. According to Michael D. Coogan's claims, however, it would have been perfectly all right for Amnon to have married his sister (he claims that the Bible was incoherent about prohibiting incest). According to the Torah, per Leviticus 18, "the children of Israel"—Israelite men and women alike—are forbidden from sexual relations between people who are "near of kin" (cf. verse 6). Siblings and half siblings (cf. verses 9 and 11). Relationships between these are particularly singled out for a curse in Deuteronomy 27, and they are of the only two kinds incestuous relationships that are among the particularly-singled-out relationships—with the other particularly-singled-out relationships, being ones of non-incestuous family betrayal (cf. verse 20) and bestiality (cf. verse 21). Incestuous relationships are considered so severe among chillul hashem, acts which bring shame to the name of God, as to be, along with the other forbidden relationships that are mentioned in Leviticus 18, punishable by death as specified in Leviticus 20. Those who committed incest were subject to 2 curses-one for committing incest and the second for breaking the Torah law. [27 Deuteronomy 22 and 26] and also the punishment of kareth. Two years later, to avenge Tamar, Absalom invited all of David's sons to a feast at sheep-shearing time, then had his servants kill Amnon after he had become drunk with wine. As a result, Absalom fled to Geshur. Although Absalom did avenge his sister’s defilement ironically he himself showed himself not to be very much different from Amnon; as Amnon had sought the advice of Jonadab in order to rape Tamar, Absalom had sought the advice of Ahitophel who advised Absalom to have incestuous relations with his father's concubines in order to show all Israel how odious he was to his father [2 Samuel 16:20]. In regard to Ahitophel’s motives, "..and great as was his wisdom, it was equalled by his scholarship. Therefore David did not hesitate to submit himself to his instruction, even though Ahithophel was a very young man, at the time of his death not more than thirty-three years old. The one thing lacking in him was sincere piety, and this it was that proved his undoing in the end, for it induced him to take part in Absalom's rebellion against David. Thus he forfeited even his share in the world to come. To this dire course of action he was misled by astrologic and other signs, which he interpreted as prophecies of his own kingship, when in reality they pointed to the royal destiny of his granddaughter Bath-sheba. Possessed by his erroneous belief, he cunningly urged Absalom to commit an unheard-of crime. Thus Absalom would profit nothing by his rebellion, for, though he accomplished his father's ruin, he would yet be held to account and condemned to death for his violation of family purity, and the way to the throne would be clear for Ahithophel, the great sage in Israel." Despite the great sins they had committed, David wept twice upon hearing the report of the death of Amnon [2 Samuel 13; 31-36] and wept seven times upon hearing the death of Absalom. Absalom was consigned to the 7th circle of Gehenna; possibly Amnon was consigned to the 2nd circle of Gehenna. records that in time David came to terms with the death of Amnon, his first-born. Methodist founder John Wesley is critical of David: "He can almost find in his heart to receive into favour the murderer of his brother. How can we excuse David from the sin of Eli, who honoured his sons more than God?" In rabbinic literature The sages of the Mishnah point out that Amnon's love for Tamar, his half-sister, did not arise from true affection, but from passion and lust, on which account, after having attained his desire, he immediately "hated her exceedingly." "All love which depends upon some particular thing ceases when that thing ceases; thus was the love of Amnon for Tamar" (Ab. v. 16). Amnon's love for Tamar was not, however, such a transgression as is usually supposed: for, although she was a daughter of David, her mother was a prisoner of war, who had not yet become a Jewess; consequently, Tamar also had not entered the Jewish community (Sanh. 21a). The incident of Amnon and Tamar was utilized by the sages as affording justification for their rule that a man must on no account remain alone in the company of a woman, not even of an unmarried one (Sanh. l.c. et seq.). According to the Babylonian Talmud, Amnon's hatred of Tamar was because the contact of his manhood with her hair had caused him to become a eunuch, and his death was a punishment from the Lord for his actions. Tomb Ibn Kathir, a famous Islamic historian, notes Gujrat, Pakistan to be the burial place of Amnon. Khawaja Gohor din or Hafiz Sham-ud-din Ghulyanvi first identified the tomb. Literary references The Spanish poet Federico García Lorca wrote a poem about Amnon's rape of his sister Tamar, included in Lorca's 1928 poetry collection Romancero Gitano (translated as Gypsy Ballads). Lorca's version is considerably different from the Biblical original – Amnon is depicted as being overcome by a sudden uncontrollable passion, with none of the cynical planning and premeditation of the original story. He assaults and rapes Tamar and then flees into the night on his horse, with archers shooting at him from the walls – whereupon King David cuts the strings of his harp.

Amu Darya

The Amu Darya (also called the Amu, Amo River, or Jayhūn, and historically known by its Latin name or Greek ) is a major river in Central Asia and Afghanistan. Rising in the Pamir Mountains, north of the Hindu Kush, the Amu Darya is formed by the confluence of the Vakhsh and Panj rivers, in the Tigrovaya Balka Nature Reserve on the border between Afghanistan and Tajikistan, and flows from there north-westwards into the southern remnants of the Aral Sea. In its upper course, the river forms part of Afghanistan's northern border with Tajikistan, Uzbekistan, and Turkmenistan. In ancient history, the river was regarded as the boundary of Greater Iran with "Turan", which roughly corresponded to present-day Central Asia. Names In classical antiquity, the river was known as the in Latin and () in Greek — a clear derivative of Vakhsh, the name of the largest tributary of the river. In Vedic Sanskrit, the river is also referred to as (). The Brahmanda Purana refers to the river as . The Avestan texts too refer to the River as Yakhsha/Vakhsha (and Yakhsha Arta ("upper Yakhsha") referring to the Jaxartes/Syr Darya twin river to Amu Darya). In Middle Persian sources of the Sassanid period the river is known as (lit. 'good river'). Amu Darya, has a flow of about 70 cubic kilometres per year on average. The name Amu is said to have come from the medieval city of Āmul, (later, Chahar Joy/Charjunow, and now known as Türkmenabat), in modern Turkmenistan, with Darya being the Persian word for "lake" and Amu being "uncle". Medieval Arabic and Islamic sources call the river Jayhoun (; also Jaihun, Jayhoon, or Dzhaykhun) which is derived from Gihon, the biblical name for one of the four rivers of the Garden of Eden. River Amu Darya passes through one of the world's highest deserts. As the river Gozan Western travelers in the 19th century mentioned that one of the names by which the river was known in Afghanistan was Gozan, and that this name was used by Greek, Mongol, Chinese, Persian, Jewish, and Afghan historians. However, this name is no longer used. "Hara (Bokhara) and to the river of Gozan (that is to say, the Amu, (called the Oxus by Europeans )) ..." "the Gozan River is the River Balkh, i.e. the Oxus or the Amu Darya ..." "... and were brought into Halah (modern day Balkh), and Habor (which is Pesh Habor or Peshawar), and Hara (which is Herat), and to the river Gozan (which is the Ammoo, also called Jehoon) ..." Description The river's total length is and its drainage basin totals in area, providing a mean discharge of around of water per year. The river is navigable for over . All of the water comes from the high mountains in the south where annual precipitation can be over . Even before large-scale irrigation began, high summer evaporation meant that not all of this discharge reached the Aral Sea – though there is some evidence the large Pamir glaciers provided enough meltwater for the Aral to overflow during the 13th and 14th centuries. Since the end of the 19th century there have been four different claimants as the true source of the Oxus: The Pamir River, which emerges from Lake Zorkul (once also known as Lake Victoria) in the Pamir Mountains (ancient Mount Imeon), and flows west to Qila-e Panja, where it joins the Wakhan River to form the Panj River. The Sarhad or Little Pamir River flowing down the Little Pamir in the High Wakhan Lake Chamaktin, which discharges to the east into the Aksu River, which in turn becomes the Murghab and then Bartang rivers, and which eventually joins the Panj Oxus branch 350 kilometres downstream at Roshan Vomar in Tajikistan. An ice cave at the end of the Wakhjir valley, in the Wakhan Corridor, in the Pamir Mountains, near the border with Pakistan. A glacier turns into the Wakhan River and joins the Pamir River about downstream. Bill Colegrave's expedition to Wakhan in 2007 found that both claimants 2 and 3 had the same source, the Chelab stream, which bifurcates on the watershed of the Little Pamir, half flowing into Lake Chamaktin and half into the parent stream of the Little Pamir/Sarhad River. Therefore, the Chelab stream may be properly considered the true source or parent stream of the Oxus. The Panj River forms the border of Afghanistan and Tajikistan. It flows west to Ishkashim where it turns north and then north-west through the Pamirs passing the Tajikistan–Afghanistan Friendship Bridge. It subsequently forms the border of Afghanistan and Uzbekistan for about , passing Termez and the Afghanistan–Uzbekistan Friendship Bridge. It delineates the border of Afghanistan and Turkmenistan for another before it flows into Turkmenistan at Atamurat. It flows across Turkmenistan south to north, passing Türkmenabat, and forms the border of Turkmenistan and Uzbekistan from Halkabat. It is then split by the Tuyamuyun Hydro Complex into many waterways that used to form the river delta joining the Aral Sea, passing Urgench, Daşoguz, and other cities, but it does not reach what is left of the sea any more and is lost in the desert. Use of water from the Amu Darya for irrigation has been a major contributing factor to the shrinking of the Aral Sea since the late 1950s. Historical records state that in different periods, the river flowed into the Aral Sea (from the south), into the Caspian Sea (from the east), or both, similar to the Syr Darya (Jaxartes, in Ancient Greek). Watershed The of the Amu Darya drainage basin include most of Tajikistan, the southwest corner of Kyrgyzstan, the northeast corner of Afghanistan, a narrow portion of eastern Turkmenistan and the western half of Uzbekistan. Part of the Amu Darya basin divide in Tajikistan forms that country's border with China (in the east) and Pakistan (to the south). About 61% of the drainage lies within Tajikistan, Uzbekistan and Turkmenistan, while 39% is in Afghanistan. The abundant water flowing in the Amu Darya comes almost entirely from glaciers in the Pamir Mountains and Tian Shan, which, standing above the surrounding arid plain, collect atmospheric moisture which otherwise would probably escape somewhere else. Without its mountain water sources, the Amu Darya would not exist—because it rarely rains in the lowlands through which most of the river flows. Of the total drainage area only about actively contribute water to the river. This is because many of the river's major tributaries (especially the Zeravshan River) have been diverted, and much of the river's drainage is arid. Throughout most of the steppe, the annual rainfall is about . History The ancient Greeks called the Amu Darya the Oxus. In ancient times, the river was regarded as the boundary between Greater Iran and Ṫūrān (). The river's drainage lies in the area between the former empires of Genghis Khan and Alexander the Great, although they occurred at very different times. When the Mongols came to the area, they used the water of the Amu Darya to flood Konye-Urgench. One southern route of the Silk Road ran along part of the Amu Darya northwestward from Termez before going westwards to the Caspian Sea. It is believed that the Amu Darya's course across the Karakum Desert has gone through several major shifts in the past few thousand years. Much of the time – most recently from the 13th century to the late 16th century – the Amu Darya emptied into both the Aral and the Caspian Seas, reaching the latter via a large distributary called the Uzboy River. The Uzboy splits off from the main channel just south of the river's delta. Sometimes the flow through the two branches was more or less equal, but often most of the Amu Darya's flow split to the west and flowed into the Caspian. People began to settle along the lower Amu Darya and the Uzboy in the 5th century, establishing a thriving chain of agricultural lands, towns, and cities. In about AD 985, the massive Gurganj Dam at the bifurcation of the forks started to divert water to the Aral. Genghis Khan's troops destroyed the dam in 1221, and the Amu Darya shifted to distributing its flow more or less equally between the main stem and the Uzboy. But in the 18th century, the river again turned north, flowing into the Aral Sea, a path it has taken since. Less and less water flowed down the Uzboy. When Russian explorer Bekovich-Cherkasski surveyed the region in 1720, the Amu Darya did not flow into the Caspian Sea anymore. By the 1800s, the ethnographic makeup of the region was described by Peter Kropotkin as the communities of "the vassal Khanates of Maimene, Khulm, Kunduz, and even the Badakshan and Wahkran." An Englishman, William Moorcroft, visited the Oxus around 1824 during the Great Game period. Another Englishman, a naval officer called John Wood, came with an expedition to find the source of the river in 1839. He found modern-day Lake Zorkul, called it Lake Victoria, and proclaimed he had found the source. Then, the French explorer and geographer Thibaut Viné collected a lot of information about this area during five expeditions between 1856 and 1862. The question of finding a route between the Oxus valley and India has been of concern historically. A direct route crosses extremely high mountain passes in the Hindu Kush and isolated areas like Kafiristan. Some in Britain feared that the Empire of Russia, which at the time wielded great influence over the Oxus area, would overcome these obstacles and find a suitable route through which to invade British India – but this never came to pass. The area was taken over by Russia during the Russian conquest of Turkestan. The Soviet Union became the ruling power in the early 1920s and expelled Mohammed Alim Khan. It later put down the Basmachi movement and killed Ibrahim Bek. A large refugee population of Central Asians, including Turkmen, Tajiks and Uzbeks, fled to northern Afghanistan. In the 1960s and 1970s the Soviets started using the Amu Darya and the Syr Darya to irrigate extensive cotton fields in the Central Asian plain. Before this time, water from the rivers was already being used for agriculture, but not on this massive scale. The Qaraqum Canal, Karshi Canal, and Bukhara Canal were among the larger of the irrigation diversions built. However, the Main Turkmen Canal, which would have diverted water along the dry Uzboy River bed into central Turkmenistan, was never built. The 1970s, in the course of the Soviet–Afghan War, Soviet forces used the valley to invade Afghanistan through Termez. The Soviet Union fell in the 1990s and Central Asia split up into the many smaller countries that lie within or partially within the Amu Darya basin. During the Soviet era, a resource-sharing system was instated in which Kyrgyzstan and Tajikistan shared water originating from the Amu and Syr Daryas with Kazakhstan, Turkmenistan, and Uzbekistan in summer. In return, Kyrgyzstan and Tajikistan received Kazakh, Turkmen, and Uzbek coal, gas, and electricity in winter. After the fall of the Soviet Union this system disintegrated and the Central Asian nations have failed to reinstate it. Inadequate infrastructure, poor water-management, and outdated irrigation methods all exacerbate the issue. Siberian Tiger Introduction Project The Caspian tiger used to occur along the river's banks. After its extirpation, the Darya's delta was suggested as a potential site for the introduction of its closest surviving relative, the Siberian tiger. A feasibility study was initiated to investigate if the area is suitable and if such an initiative would receive support from relevant decision makers. A viable tiger population of about 100 animals would require at least of large tracts of contiguous habitat with rich prey populations. Such habitat is not available at this stage and cannot be provided in the short term. The proposed region is therefore unsuitable for the reintroduction, at least at this stage. Literature The Oxus river, and Arnold's poem, fire the imaginations of the children who adventure with ponies over the moors of the West Country in the 1930s children's book The Far-Distant Oxus. There were two sequels, Escape to Persia and Oxus in Summer. Robert Byron's 1937 travelogue, The Road to Oxiana, describes its author's journey from the Levant through Persia to Afghanistan, with the Oxus as his stated goal.

Muslim conquests of Afghanistan

The Muslim conquests of Afghanistan began during the Muslim conquest of Persia as the Arab Muslims migrated eastwards to Khorasan, Sistan and Transoxiana. Fifteen years after the Battle of Nahāvand in 642 AD, they controlled all Sasanian domains except in Afghanistan. Fuller Islamization was not achieved until the period between 10th and 12th centuries under Ghaznavid and Ghurid dynasty's rule who patronized Muslim religious institutions. Khorasan and Sistan, where Zoroastrianism was well-established, were conquered. The Arabs had begun to move towards the lands east of Persia and in 652 AD they captured the city of Herat, establishing an Arab governor there. The Muslim frontier in modern Afghanistan had become stabilized after the first century of Hijri calendar as the relative importance of the Afghan areas diminished. From historical evidence, it appears Tokharistan (Bactria) was the only area heavily conquered by Arabs where Buddhism flourished. Balkh's final conquest was undertaken by Qutayba ibn Muslim in 705. Hui'Chao, who visited around 726, mentions that the Arabs ruled it and all the inhabitants were Buddhists. The eastern regions of Afghanistan were at times considered politically as parts of India. Buddhism and Hinduism held sway over the region until the Muslim conquest. Kabul and Zabulistan which housed Buddhism and other Indian religions, offered stiff resistance to the Muslim advance for two centuries, with the Kabul Shahi and Zunbils remaining unconquered until the Saffarid and Ghaznavid conquests. The significance of the realm of Zun and its rulers Zunbils had laid in them blocking the path of Arabs in invading the Indus Valley. The Caliph Al-Ma'mun (r. 813–833 AD) was paid double the tribute by the Rutbil. His were the last Arab expeditions on Kabul and Zabul. The king of Kabul was captured by him and converted to Islam. The last Zunbil was killed by Ya'qub bin al-Layth along with his former overlord Salih b. al-Nadr in 865. Meanwhile, the Hindu Shahi of Kabul were defeated under Mahmud of Ghazni. Indian soldiers were a part of the Ghaznavid army, Baihaki mentioned Hindu officers employed by Ma'sud. The 14th-century scholar Muslim scholar Ibn Battuta described the Hindu Kush as meaning "slayer of Indians", because large numbers of slaves brought from India died from its treacherous weather. The geographer Ya'qubi states that the rulers of Bamiyan, called the Sher, converted in the late 8th century. Ya'qub is recorded as having plundered its pagan idols in 870 while a much later historian Shabankara'i claims that Alp-Tegin obtained conversion of its ruler in 962. No permanent Arab control was established in Ghur and it became Islamised after Ghaznavid raids. By the time of Bahram-Shah, Ghur was converted and politically united. In the late 15th century, Babur, the founder of the Mughal Empire, arrived from Fergana and captured Kabul from the Arghun dynasty. Between the 16th and 18th centuries, the Mughal emperor Shah Jahan and Aurangzeb ruled parts of the eastern territory. The Pashtun habitat during their conquest by Mahmud was located in the Sulaiman Mountains in the south of Afghanistan. They were enlisted by both Sabuktigin and Mahmud according to Tarikh-i-Yamini. Prior to Pashtun migration to the Kabul River valley, Tajiks formed the dominant population of Kabul, Nangarhar, Logar Valley and Laghman in east Afghanistan. The Pashtuns later began migrating westward from Sulaiman Mountains in the south, and displaced or subjugated the indigenous populations such as Tajiks, Hazaras, the Farsiwanis, before or during 16th and 17th centuries. The successive wave of Pashtun immigration displaced the original Kafir and Pashayi people from the Kunar Valley and Laghman Valley, the two eastern provinces near Jalalabad, to the less fertile mountains. Before their conversion, the Kafir people of Kafiristan practiced a form of ancient Hinduism infused with locally developed accretions. The region from Nuristan to Kashmir was host to a vast number of "Kafir" cultures. They were called Kafirs due to their enduring paganism, remaining politically independent until being conquered and forcibly converted by Afghan Amir Abdul Rahman Khan in 1895–1896 while others also converted to avoid paying jizya. Arab conquests and rule During the Muslim conquest of Persia, the Arabs were drawn eastwards from the Iraqi plains to central and eastern Persia, then to Media, into Khorasan, Sistan and Transoxania. 15 years after the Battle of Nahāvand, the Arabs controlled all Sasanian domains except the parts of Afghanistan and Makran. Nancy Dupree states that advancing Arabs carrying the religion of Islam easily took over Herat and Sistan, but the other areas often revolted and converted back to their old faiths whenever the Arab armies withdrew. The harshness of the Arab rule caused the native dynasties to revolt after the Arab power weakened like the Saffarids founded by the zealous Yaqub who conquered many cities of the region. Historian Cameron A. Petrie states that while the Arab expansion had both social and religious motives, it was their extraction of taxes from the subjugated people that invited the numerous local rebellions. Medieval Islamic scholars divided modern-day Afghanistan into two regions - the provinces of Khorasan and Sistan. Khorasan was the eastern satrapy of the Sasanian Empire, containing Balkh and Herat. Sistan included a number of Afghan cities and regions including Ghazni, Zarang, Bost, Qandahar (also called al-Rukhkhaj or Zamindawar), Kabul, Kabulistan and Zabulistan. Before Muslim rule, the regions of Balkh (Bactria or Tokharistan), Herat and Sistan were under Sasanian rule. Further south in Balkh region, in Bamiyan, indication of Sasanian authority diminishes, with a local dynasty apparently ruling from the late antiquity, probably Hepthalites subject to the Yabgu of Western Turks. While Herat was controlled by Sasanians, its hinterlands were controlled by northern Hepthalites who continued to rule the Ghurid mountains and river valleys well into the Islamic era. Sistan was under Arabs, but Qandahar remained out of Arab rule. Kabul and Zabulistan, housed Indic religions with the Zunbils and Kabul Shahis offering stiff resistance to Muslim rule for two centuries until Saffarid and Ghaznavid conquests. In Afghanistan, the frontier of the Islamic conquest had become more or less stationary by the end of the first century of Hijri calendar. One reason was that the relative importance of Sistan and Baluchistan had begun to diminish by the time of Mu'awiyah I, when the conquests of Bactria and Transoxania were undertaken. In addition, the conquest in the eastern direction was extended to Makran and Sind, with Muslim colonies becoming established there in 711–12. Sistan The earlier Arabs called Sistan as Sijistan, from the Persian word Sagestan. It is a lowland region, lying round and eastwards from the Zarah lake, which includes deltas of Helmand and other rivers which drain into it. The Muslim conquest of Sistan began in 23 AH (643-644 AD) when Asim bin Amr and Abdallah ibn Amir invaded the region and besieged Zaranj. The Sistanis concluded a treaty with Muslims, mandating them to pay the kharaj. The cash-strapped Sasanian king Yazdegerd III who had a large retinue, had fled to Kerman in 650. He had to flee from Kerman to Sistan after his arrogance angered the marzban of the place, eluding an Arab force from Basra which defeated and killed the marzban. Yazdegerd lost the support of governor of Sistan after demanding taxes from him and had to leave for Merv. It is not known whether this governor was a Sasanian prince or a local ruler at that time. The Arabs had campaigned in Sistan a few years earlier and Abdallah b. Amir had now gone in pursuit of Yazdegerd. He arrived in Kirman in 651 and sent a force under Rabi ibn Ziyad al-Harithi to Sistan. Rabi crossed the desert between Kirman and Sistan, reaching the fortress of Zilaq which was within five farsangs of the Sistan frontier. The fort was surrendered by its dihqan. The fortress of Karkuya, whose fire temple is mentioned in the anonymously authored Tarikh-e-Sistan, along with Haysun and Nashrudh, surrendered to Rabi. Rabi then encamped in Zaliq and projected the seizure of Zarang, which though had earlier submitted to Arabs, needed to be subdued again. Although its marzaban Aparviz put up a strong resistance, he was forced to surrender. The Zaranj forces had received heavy casualties during the battle with Arab forces and were driven back to the city. According to sources, when Aparviz appeared before Rabi to discuss the terms, he found the Arab general was sitting on a chair made out of two dead soldiers and his entourage had been instructed to make seats and bolsters in the same fashion. Aparviz was terrified into submission and wished to spare his people of this fate. A peace treaty was concluded with payment of heavy dues. The treaty mandated one million dirhams as annual tribute, in addition to 1,000 slave boys bearing 1,000 gold vessels. The city was also garrisoned by Rabi. Rabi thus succeeded in gaining Zarang with considerable difficulty and remained at the place for several years. Two years later, the people of Zarang rebelled and expelled Rabi's lieutenant and garrison. Abdallah b. Amir sent 'Abd ar-Rahman b. Samura to take back the city, who also added Bust and Zabul to Arab gains. 'Abd ar-Rahman besieged Zaranj and after the marzban surrendered, the tribute was doubled. The tribute imposed on Zarang was 2 million dirhams and 2,000 slaves. During the period of the first civil war in the Arab caliphate (656-661), rebels in Zarang imprisoned their governor while Arab bandits started raiding remote towns in Sistan to enslave people. They gave in to the new governor Rib'i, who took control of the city and restored law and order. 'Abdallah b. Amir was made the governor of Basra and its eastern dependencies again from 661 to 664. Samura was sent back to Sistan in 661. An expedition to Khorasan was sent under him that included reputed leaders like 'Umar b. 'Ubaydillah b. Ma'mar, 'Abdullah b. Khazim, Qatariyy b. al-Fuja'a and Al-Muhallab ibn Abi Sufra. He reconquered Zarang, attacked Zabulistan's ruler called the "Zunbil" and entered Kabul after a brief siege. Ziyad ibn Abihi was appointed governor of Basra in 664 and was also made governor of Kufa and its dependencies in 670, making him the viceroy of the entire eastern half of the Islamic empire. He sent his kinsman Ubaydallah b. Abi Bakra to destroy the Zoroastrian fire temples in Fars and Sistan, confiscate their property and kill their priests. While the fire temple of Kariyan was destroyed, the one at Karkuya survived along with its herbad. Ziyad's son Abbad was appointed governor of Sijistan by Mu'awiya I in 673 and served until 681. During the course of his governorship, the province apparently remained stable and Abbad led an eastward expedition which brought Kandahar to the caliphate. Caliph Yazid I replaced Abbad with his brother Salm, who was already governor of Khurasan. Khorasan There is general agreement among Arabic sources that Khorasan's conquest began in the reign of Uthman under Abdallah b. Amir, who had been appointed the governor of Basra (r. 649–655). Sayf's tradition however disagrees with this, dating it to 639 under the reign of Umar with Ahnaf ibn Qais leading the expedition. Al-Tabari meanwhile relates that Ahnaf's conquests occurred in 643. This could be because of confusion of Ahnaf's later activities under Ibn Amir and an attempt to magnify his role in Khorasan's conquest. The conquest of southern Persia was completed by 23 AH with Khorasan remaining the only region remaining unconquered. Since the Muslims did not want any Persian land to remain under Persian rule, Umar ordered Ahnaf b. Qais to march upon it. After capturing the towns of Tabas and Tun, he attacked the region's easternmost city Herat. The Persians put up stiff resistance but were defeated and surrendered. A garrison was deployed in the city, while a column was detached which subjugated Nishapur and Tus. Umar had dispatched Ahnaf with 12,000 men from Kufa and Basra after Yazdegerd who had fled to Merv. After the Arabs arrived there, Yazdegerd fled to Marw al-Rudh from where he sent ambassadors to the Khakan of the Turks, the ruler of Soghd and the Chinese emperor, asking for their assistance. Yazdegerd later fled to Balkh, where he was defeated by the Arabs and fled across Oxus River. Umar forbade Ahnaf from crossing the river as the land beyond it was unknown to Arabs and was very far for them. Yazdegerd proceeded to Soghd whose ruler supplied him with a large army. The Khaqan of Turks after assembling the troops from Ferghana, crossed the Oxus along with Yazdegerd and marched to Balkh. Ribi' b. Amir meanwhile retired with Kufan troops to Marw al-Rudh where he joined al-Ahnaf. The Sasanian king and the Khakan leading an army of 50,000 cavalry composed of men from Soghd, Turkestan, Balkh and Tokharistan, arrived at Marw al-Rudh. Ahnaf had an army of 20,000 men. The two sides fought each other from morning till evening for two months at a place called Deir al-Ahnaf. The fighting at Deir al-Ahnaf went on until Ahnaf, after being informed of a Turkic chief inspecting the outposts, went there during a particular night and successively killed three Turkic chiefs during their inspection. After learning of their deaths, the Khakan became afflicted by it and withdrew to Balkh, then he withdrew across the river to Turkestan. Yazdegerd meanwhile left from Marw al-Rudh to Merv, from where he took his empire's wealth and proceeded to Balkh to join the Khakan. He told his officials that he wanted to hand himself to the protection of the Turks, but they advised him against it and asked him to seek protection from the Arabs which he refused. He left for Turkestan while his officials took away his treasures and gave them to Ahnaf, submitting to the Arabs and being allowed to go back to their respective homes. Abdullah b. Amir went to Khorasan from Kerman in 650 and set out along with a vanguard of Tamimi Arabs and 1,000 asawira via Quhistan. The people of Tabasayn had broken their peace treaty and had allied with the Hepthalites of Herat. al-Ahnaf reconquered Quhistan and defeated Herat's Hepthalites at Nishapur. The kanarang or marzaban of Tus asked the Arabs for assistance against the raiding Hepthalites of Herat and Badghis. He agreed to a peace agreement for 600,000 dinars. The Hepthalite action prompted the Muslims undertaking military operation to secure their positions in Khorasan. After the fall of Tus, Ibn Amir sent out an army against Herat. The ruler (marzaban or azim) of the place agreed to a peace treaty for Herat, Badghis and Pushang for a tribute of 1 million dirhams. The ruler who was known as azim or the "mighty one" in Futuh al-Buldan, may have been a Hepthalite chief. The Rashidun Caliphs followed the earlier rule of Muhammad of imposing jizya on several bodies jointly and in some cases also imposed the condition that they host Muslims. This rule was followed in most Iranian towns, with the jizya not specified on per capita basis, but being left to the local rulers, though some Muslim commanders stressed the amount on the ability of the ruler to pay. The same wording can be seen in Ibn Amir's treaty. In 652, Ibn Amir sent al-Ahnaf to invade Tokharistan with 4,000 Arabs and 1,000 Iranian Muslims (evidently the Tamimis and asawira), probably because of assistance of its ruler to Yazdegerd's son Peroz. While Marw al-Rudh's garrison agreed to a peace term for the entire district under 300,000 dirhams, the town itself remained besieged. It was the last major stronghold of Sasanians and fell to al-Ahnaf after a fierce battle. After bloody fighting, its marzaban agreed to a peace treaty for 60,000 or 600,000 dirhams as well as a mutual defence pact. He was also allowed to keep his ancestral lands, for the office of marzaban to be hereditary in his family, and to be exempt from taxes along with his whole family. Baladhuri quotes Abu Ubayda as stating that the Turks were supporting the inhabitants of the town. These Turks were Hepthalites, probably from Guzgan, which may explain the reason behind the Arabs next attacking Guzgan, Faryab and Talqan. Al-Mada'ini specifically states that Ahnaf while leading the next expedition, did not want to ask for assistance from the non-Muslims of Marw al-Rudh, probably as he did not trust them. The Arabs camped at Qasr al-Ahnaf, a day's march to the north of Marw al-Rudh. The 30,000-strong army comprising troops of Guzgan, Faryab and Talqan, supported by the Chaghanian troops, advanced to meet them. The battle was inconclusive, but the opposing side dispersed with some remaining at Guzgan while the Arabs withdrew to Marw al-Rudh. Ahnaf sent an expedition, led by al-Aqra' b. Habis and apparently consisting exclusively of Tamimis, to Guzgan. The Arabs defeated Guzgan and entered it by force. Ahnaf meanwhile advanced towards Balkh, making peace treaties with Faryab and Taloqan along the way. The permanent pacification of Khorasan was a protracted affair with the local potentates often rebelling and appealing to outside powers like the Hepthalites, Western Turks or Turgesh, Sogdians and the imperial Chinese who claimed a degree of suzerainty over Central Asia, for help. Within a year after Yazdegerd's death, a local Iranian notable named Qarin started a revolt against the Arabs in Quhistan. He gathered his supporters from Tabasayn, Herat and Badghis, assembling a reported army of 40,000 insurgents against Arabs in Khorasan. The Arabs made a surprise attack however, killing him and many of his people while many others were taken captive. It was expected that the recently subjugated people would revolt. However, in Khorasan, no all-out effort seems to have been undertaken to the expel the Arabs after Qarin's rebellion. Chinese sources state that there was an attempt to restore Peroz by Tokharistan's army, however this episode is not confirmed by Arab sources. Peroz had settled among the Turks, took a local wife and had received troops from the king of Tokharistan. In 661, he established himself as king of Po-szu (Persia) with Chinese help in a place the Chinese called Ja-ling (Chi-ling), which is assumed to be Zarang. His campaigns are reflected in Muslim sources, which mention revolts in Zarang, Balkh, Badghis, Herat, Bushanj and also in Khorasan during the First Fitna period in reigns of Ali and Muawiyah. Though they do not mention Peroz, they do state that Ali's newly appointed governor of Khorasan had heard in Nishapur that governors of the Sasanian king had come back from Kabul and Khorasan had rebelled. However, the region was reconquered under Muawiyah. Piroz went back to the Tang Empire's capital and was given a grandiose title as well as permission to build a fire temple in 677. Yazid ibn al-Muhallab succeeded his father as governor of Khorasan in 702 and campaigned in Central Asia, but achieved little success apart from Nezak Tarkhan's submission at Badghis. Tokharistan Tokharistan, roughly ancient Bactria, is today divided between Afghanistan, Tajikistan and Uzbekistan. According to the most general usage of the name, Tokharistan is the wide valley around the upper Oxus river surrounded by mountains on three sides before the river moves into open plains. The major city was Balkh, one of the greatest urban centers of northeastern Iran. It was located upon crossroads and conduits of trade in many directions, enabling control of these routes if it was conquered. During the governorship of Abu 'l Abbas 'Abdallah b. Tahir (r. 828–845), a list of districts (kuwar) of the region exists, including as far as Saghaniyan in the north and Kabul in the south. Other places listed are Tirmidh, Juzjan, Bamiyan, Rūb and Samanjan. Some Arab geographers used the name only for the southern part of Oxus valley. Balkh was also a part of Khorasan along with other areas through varying extensions of time. Per al-Tabari, Yazdegerd fled from Marw-al Rudh to Balkh during Ahnaf's conquest of Khorasan in 643. He fortified himself but was defeated by the Arabs and fled across the Oxus River. Yazdegerd proceeded to Soghd, whose ruler supplied him a large army. The Khaqan of Turks after assembling the troops from Ferghana, crossed the Oxus along with Yazdegerd and marched to Balkh. In 652, Ibn Amir sent al-Ahnaf to invade Tokharistan with 4,000 Arabs and 1,000 Iranian Muslims (evidently the Tamimis and asawira), probably because of assistance of its ruler to Yazdegerd's son Peroz. He approached Balkh after conquering Marw al-Rudh and fighting an inconclusive battle with a 30,000-strong force from Guzgan, Faryab and Talqan. After arriving at Balkh, he besieged the city, with its inhabitants offering a tribute of 400,000 or 700,000 dirhams. He deputed his cousin to collect the tribute and advanced to Khwarezm but returned to Balkh as winter approached. It was in Balkh in fall of 652 when the local people introduced his cousin Asid to gifting gold and silver to their governor during Mihrijan. Ziyad b. Abi Sufyan reorganised Basra and Kufa, excluding many from the diwan and inspiring him to settle 50,000 families in Khorasan. Both Baladhuri and Mad'aini agree upon the number, though the latter states each half were from Basra and Kufa. Al-'Ali disagrees, stating the Kufans were 10,000. Ghalib had been unsuccessful in his expedition, and Rabi b. Ziyad al-Harithi, who was appointed governor of Khorasan in 671, led the settlement expedition. He advanced to Balkh and made a peace treaty with the locals who had revolted after al-Ahnaf's earlier treaty. Qutayba ibn Muslim led the final conquest of Balkh. He was tasked with subduing the revolt in Lower Tokharistan. His army was assembled in the spring of 705 and marched through Marw al-Rudh and Talqan to Balkh. Per one version in Tarikh al-Tabari, the city was surrendered peacefully. Another version, probably to promote a Bahilite claim on the Barmakids, speaks of a revolt among the residents. The latter may be the correct version as Tabari describes the city as ruined four years later. The wife of Barmak, a physician of Balkh, was taken captive during the war and given to 'Abdullah, Qutayba's brother. She was later restored to her lawful husband after spending a period in 'Abdullah's harem. Khalid was thus born in 706 and Abdallah accepted the implications of paternity without disturbing Barmak's conventional responsibilities or affecting Khalid's upbringing. In 708–709, the Ispahbadh, who was a local ruler, received a letter from the Hepthalite rebel Nezak Tarkhan, who was trying to unite the aristocracy of Tokharistan against Qutayba. The Arabs built a new military encampment called Baruqan two farsangs away from the city. In 725, the governor Asad ibn Abdallah al-Qasri had the city restored after a feud among Arab troops, with Barmak being employed as his agent for the task. Early Arabs tended to treat Iran as a single cultural unit, however it was a land of many countries with distinct populations and cultures. From historical evidence, it appears that Tokharistan was the only area heavily colonized by Arabs where Buddhism flourished, and the only area incorporated into the Arab empire where Sanskrit studies were pursued up to the conquest. The grandson of Barmak was the vizier of the Arab empire and took personal interest in Sanskrit works and Indian religions. The eighth-century Korean traveller Hui'Chao records Hinayanists in Balkh under Arab rule. He visited the area around 726, mentioning that the true king of Balkh was still alive and in exile. He also describes all the inhabitants of the regions as Buddhists under Arab rule. Other sources indicate however that the Bactrians practiced many different religions. Among Balkh's Buddhist monasteries, the largest was Nava Vihara, later Persianized to Naw Bahara after the Islamic conquest of Balkh. It is not known how long it continued to serve as a place of worship after the conquest. Accounts of early Arabs offer contradictory narratives. Per al-Baladhuri, its stupa-vihara complex was destroyed under Muawiyah in 650s. Tabari while reporting about the expedition in 650s, does not mention any tension around the temple, stating that Balkh was conquered by Rabi peacefully. He also states that Nizak went to pray at the site during his revolt against Qutayba in 709, implying it may not have been destroyed. Also, the tenth-century geographical treatise Hudud al-'Alam describes remaining royal buildings and Naw Bahara's decorations including painted image and wonderful works, probably secco or fresco murals and carvings on the temple's walls that survived into the author's time. Sanskrit, Greek, Latin and Chinese sources from the 2nd century BC to the 7th century AD, identify a people called "Tukharas", in the country later called Tukharistan. Badakhshan was earlier the seat of the Tukharas. There is no precise date for the Arab conquest of Badakhshan nor any record of how Islam was introduced there. Al-Tabari too mentions this region only once. In 736, Asad ibn Abdallah al-Qasri sent an expedition into Upper Tokharistan and Badakhshan against the rebel Al-Harith ibn Surayj who had occupied the fortress of Tabushkhan. Juday' b. 'Ali al-Kirmani, who was sent on the expedition against al-Harith, captured Tabushkhan. Juday also had its captive defenders killed while its women and children were enslaved and sold in Balkh despite being of Arab origin. al-Harith later allied with the Turgesh and continued his rebellion until being pardoned by Caliph Yazid b. Walid in 744. Taking advantage of the factional fighting among the Arabs, Transoxania started rebelling and Asad b. 'Abdallah in response attacked Khuttal in 737. Armed forces of Soghd, Chach and many Turks, led by the Turkish Khagan Sulu, arrived to assist them. Asad fled leaving behind the baggage of plunder from Khuttal. When he returned with the main body of his troops, the Turks retired to Tokharistan and he returned to Balkh. In December 737, the Turgesh attacked Khulm but were repelled by the Arabs. Bypassing Balkh, they captured Guzgan's capital and sent out raiding parties. Asad mounted a surprise attack on the Turks at Kharistan, who only had 4,000 troops. The Turgesh suffered a devastating defeat and lost almost whole of their army. Sulu and al-Harith fled to the territory of Tokharistan's Yabghu, with Sulu returning to his territory in winter of 737–738. The Zunbils The Zunbils in the pre-Saffarid period ruled in Zabulistan and Zamindawar, stretching between Ghazni and Bost, and had acted as a barrier against Muslim expansion for a long time. Zamindawar is known to have a shrine dedicated to the god Zun. It has been linked with the Hindu god Aditya at Multan, pre-Buddhist religious and kingship practices of Tibet, as well as Shaivism. The followers of the Zunbils were called Turks by the Arabic sources, however they applied the name to all their enemies in eastern fringes of Iran. They are described as having Turkish troops in their service by sources like Tabari and Tarikh-e-Sistan. The first time the title of Zunbil appears in Arabic sources, it does so along with that of the Kabul Shah and according to Tabari was the title of the brother of Kabul's king (either Barha Tegin or Tegin Shah). The Zunbil apparently broke away from the overlordship of Kabul around 680 AD and established his own kingdom in Zabulistan and al-Rukhkhaj. The kingdom of Zabulistan (ar-Rukhkhaj) with its capital at Ghazni, where the king Zunbil or Rutbil resided, is mentioned by Chinese sources under the suzerainty of Jabghu of Turkestan. The significance for Arabs of the realm of Zun and its rulers was them preventing their campaigns from invading the Indus Valley through eastern and southern Afghanistan. It was only under the early Saffarids that mass-Islamization and conquests of the region took place unlike the plunder-raids or tribute levies of Arabs. The expeditions under Caliph al-Ma'mun against Kabul and Zabul were the last ones and the long conflict ended with the dissolution of the Arab empire following soon thereafter. Sakawand in Zabulistan was a major centre of Hindu pilgrimage. 7th century After appearing at Zarang, Abd al-Rahman ibn Samura and his force of 6,000 Arabs penetrated to the shrine of Zun in 653–654. He broke off a hand from the idol of Zun and plucked out the rubies used as its eyes to demonstrate to the marzban of Sistan that the idol could neither hurt nor benefit anyone. He also took Zabul by treaty by 656. In the shrine of Zoon in Zamindawar, it is reported that Samura "broke off a hand of the idol and plucked out the rubies which were its eyes in order to persuade the marzbān of Sīstān of the god's worthlessness." Samura explained to the marzbān: "my intention was to show you that this idol can do neither any harm nor good." Bost and Zabul submitted to the Arab invader by treaty in 656 CE. The Muslims soon lost these territories during the First Civil War (656-661). In 665 CE, after being reappointed to Sistan under Muawiyah, Samura defeated Zabulistan whose people had broken the earlier agreement. Samura was replaced as governor by Rabi b. Ziyad and died in 50 AH (670 AD), while the king of Zabul rebelled along with the Kabul Shah and the two together reconquered Zabulistan and Rukhkhaj according to al-Baladhuri. Ar-Rabi, the Arab governor, however attacked the Zunbil at Bust and made him flee. He then pursued him to Rukhkhaj, where he attacked him and then subdued the city of ad-Dawar. Ziyad b. Abi Sufyan was appointed governor of Basra in 665, with Khorasan and Sistan coming under his mandate as well. He had first appointed Rabi to Sistan but replaced him later with 'Ubaydallah b. Abi Bakra. During this period, Zunbil's fierce resistance continued until he finally agreed to pay one million dirhams per Baladhuri and Tarikh-e-Sistan. The Zunbil also negotiated for a peace treaty for both Zabul ans Kabul. Al-Baladhuri records that under Muawiyah, Sistan's governor 'Abbad b. Ziyad b. Abihi raided and captured the city of Qandahar after bitter fighting. He also mentions the characteristic high caps of the people of the city. Though his text is somewhat ambiguous, it seems that 'Abbad had renamed the town as Abbadiya after himself. The Muslim rule was probably toppled and the name is never heard after his governorship ended in 680–1, by 698 there was no Muslim-controlled region east of Bost. The city was ruled by Arab Muslims and Zunbils, and then later Saffarids and Ghaznavids. It is infrequently mentioned in the early Islamic sources. In 681, Salm b. Ziyad was appointed the governor of Khorasan and Sistan by Yazid I. He appointed his brother Yazid b. Ziyad, apparently to lead a military expedition against the Zunbil of Zabulistan. The expedition however was disastrous, with Yazid being killed, his brother Abu-'Ubayda captured, while Arabs received heavy casualties. Salm sent an expedition by Talha b. 'Abdillah al-Khuzai to rescue his brother and pacify the region. The Arab captives were ransomed for half million dirhams and the region was pacified more through diplomacy than force. After Talha's death in 683–684, a virtual anarchy was unleashed amongst Sistan's Arabs. His army refused allegiance to Yazid or Muawiyah II and his son 'Abadallah had to abandon Zarang, which was left without any in charge. Many Arabs took over various quarters of Zarang and areas of Sistan. This prompted the Zunbil and his allies, who had already inflicted a humiliating defeat on the Arabs earlier, to intervene in the Arab affairs at Sistan and Bust. Baladhuri says of this period: During the Second Fitna period, the Zunbil attacked Sistan in 685 but was defeated and killed by the Arabs. Abdalmalik appointed Umayya b. 'Abdillah b. Khalid b. Asid as governor of Khorasan in 74 AH (693-4 AD), with Sistan included under his governorship. Umayya sent his son Abdullah as head of the expedition in Sistan. Though initially successful, the new Zunbil was able to defeat them. Per some accounts, Abdullah himself was killed. Umayya was dismissed and Sistan was added to the governorship of al-Hajjaj ibn Yusuf. Under Al-Hajjaj Al-Hajjaj, who had become governor of Iraq and the East in 78 AH (697–98 AD), had appointed Ubaidallah, who was a mawla of mixed Abyssinian and Iraqi-Persian origins, as his deputy in Sistan. The Zunbils, who had been left unchecked, had completely stopped paying the tribute. This provided a pretext to terminate the peace treaty between the two sides. Ubaidallah was appointed for an expedition against them in 698 and was ordered by Al-Hajjaj to "attack until he laid waste to Zunbil's territories, destroyed his strongholds, killed all his fighting men and enslaved his progeny". The ensuing campaign was called the "Army of Destruction" (Jaish al-Fana). However, it ended disastrously for the Arabs. Al-Baladhuri's account on the authority of Al-Mada'ini in Futuh al-Buldan and Ansab al-Ashraf, is the fullest documentation of the campaign. Tabari's account runs parallel but is based on Abu Mikhnaf and does not include the poem of A'sha Hamdan included in Ansab al-Ashraf. Ibn Qutaybah's Kitab al-Ma'arif only makes a bare mention. Ta'rikh al-khulafa' has a more detailed account and epitomises accounts of Tabari and Baladhuri. Tarikh-e-Sistan confuses the campaign with another one against the Khwarij of Zarang. The army consisted of Iraqis from Basra and Kufa, though Baladhuri mentions presence of some Syrians. Ubaidallah himself led the Basrans while the Tabi Shuraih b. Hani' al-Harithi ad-Dabbi led the Kufans. They marched to Zamindawar or al-Rukhkhaj (the classical Arachosia) but found it barren and foodless. Their advance probably happened in summer of 698, as A'sha Hamdan's poem refers to the scorching heat they had to endure. In Zabulistan's regions of Ghazni and Gardiz, they plundered a significant amount of cattle and other animals, in addition to destroying various strongholds. The Zunbils, who were devastating the countryside whilst retreating, were luring the Arabs into a trap to an inhospitable and foodless terrain. Futuh al-Buldan states that the Muslims almost penetrated Kabul. Tabari meanwhile says that they came within 18 farsakhs of the summer capital of Zunbils in the Qandahar region. The plan of the Zunbils worked and they trapped the Arabs into a valley. Ubaidallah realizing the gravity of the situation, offered 500,000 or 700,000 dirhams as well as his three sons along with some Arab leaders as hostages while promising not to raid again during his tenure as Sistan's governor. Shuraih, who had earlier advised retreat, felt a withdrawal would be dishonorable. He was joined by a group of people into the battle, and all but a handful of them were killed. The remnant of the Arab army withdrew back to Bust and Sistan, suffering from starvation and thirst. Many died in the "Desert of Bust", presumably the Registan Desert, with only 5,000 making it back to Bust. Many of those who survived died by gorging themselves on the food sent to them according to Tabari. Ubaidallah had arranged food for them after seeing their suffering and himself died, either from grief or an ear affliction. Al-Hajjaj prepared another expedition in 699, reportedly of 40,000 troops from Kufa and Basra under Abdurrahman b. Muhammad b. al-Ash'ath. Though disguised as a military expedition, it was actually a forced migration of the elements from the two Iraqi cities troublesome to Hajjaj. It was equipped to the best standards and was called the "Army of Peacocks" because of the men included in its ranks. It included the proudest and most distinguished leaders of Iraq led by Ibn al-Ash'ath, grandson of Al-Ash'ath ibn Qays. It also included distinguished elders who served in the first armies of conquest as well as those who fought at Battle of Siffin. This Arab army arrived in Sistan in the spring of 699. The Arabs advanced east into Zabulistan and won several victories. However the troops did not want to fight in this inhospitable region and started becoming restive. Al-Hajjaj instructed them to continue the advance into Zabulistan's heart no matter what it took, making it clear to them he wanted them to return to their homes. Ibn al-Ash'ath also made an agreement with the Zunbils, that no tribute would be demanded if he won and in case he lost, he would be sheltered to protect him from Al-Hajjaj. The troops mutinied against Hajjaj's enforced emigration and returned to Iraq but were crushed by the Syrian troops. They fled back to the east while Ibn al-Ash'ath fled to Sistan where he died in 704 AD. When Ibn al-Ash'ath returned to Sistan in 702-703 AD, he wasn't allowed into Zarang and fled to Bust where he was abducted by Iyad b. Himyan al-Bakri as-Sadusi, whom he had appointed as the deputy over Bust, so Iyad could resecure favor of al-Hajjaj. The Zunbil however attacked the town and threatened to slaughter or enslave everyone there unless Ibn al-Ash'ath was handed over to him. Iyad set him free and he went to the Zunbil's territory along with his army. The Zunbil was however persuaded by Al-Hajjaj's representative to surrender him. His fate is however unclear. Per some accounts, he committed suicide, while according to others he was killed by the Zunbil, who sent his head to the Umayyads in Sistan. Following this, a truce was declared between Al-Hajjaj and the Zunbil, in return for the latter paying tribute in kind and in return, Al-Hajjaj promised not to attack him. From 8th century Qutayba b. Muslim, the conqueror of Transoxiana, preferred not to fight the Zunbils and accepted an offer of a rather minimal tribute from them, calling Sijistan an "ill-omened front". Until the reign of Hisham ibn Abd al-Malik, the Sijistan front had ceased to be volatile as the Arabs had given up on conquering the area and no fighting occurred for a long period. This in turn holding led to Zunbils not even paying a token tribute. The policy began to change under Hisham. Khalid al-Qasri in Iraq appointed Yazid b. al Ghurayf al-Hamdani as Sistan's governor, a Syrian from Jund al-Urdunn, in 725. Yazid resumed the campaign by sending an army under the command of Balal b. Abi Kabsha. They however did not obtain anything from the Zunbils. The new governor of Sistan, al-Asfah b. 'Abd Allah al-Kalbi, a Syrian, embarked on an ambitious policy of campaigning against the Zunbils. The first one was carried out in 726. During the second one in late 727–728, he was warned by the Sijistanis who were with him to not campaign in winter, especially in the mountain defiles. Per Ya'qubi, his army was completely annihilated by the Zunbils. Per Tarikh al-Sistani, al-Asfah managed to get back to Sistan where he died. The next two governors did not undertake any campaigns. The Zunbil was unable to take advantage of the annihilation of al-Asfah's army, but the defeat was a heavy one. It would become one in a series of blows for the caliphate. The Sistan front remained quiet in the latter part of Abd al-Malik's reign except perhaps the Kharjite activity, with long tenures and blank records of 'Abd Allah b. Abi Baruda and Ibrahim b. 'Asim al-'Uqayli suggesting that the instability in the region had been controlled to an extent. It appears this was only possible because no more campaigns were undertaken against the Zunbils. Al-Mansur sent Ma'n b. Zaida ash-Shabani to Sistan in response to the disturbances there. Ma'n along with his nephew Yazid b. Ziyad undertook an expedition against the Zunbil for making him obedient and restoring the tribute not paid since the time of al-Hajjaj. It is especially well-documented by al-Baladhuri. He ordered the Zunbil to pay the tribute and was offered camels, Turkish tents and slaves, but this did not placate him. Per al-Baldahuri, under the reign of al-Mansur, Hisham b. 'Amr al-Taghlibi after conquering Kandahar, destroyed its idol-temple and built a mosque in its place. Ma'n and Yazid advanced into Zamindawar but the Zunbil had fled to Zabulistan. They nonetheless pursued and defeated him, taking 30,000 as captives, including Faraj al-Rukhkhaji, who would later become a secretary of the department of private estates of the Caliph under al-Ma'mun. Zunbil's deputy Mawand (who is recorded as his son-in-law Mawld in Tarikh-e-Sistan) offered submission, which was requested, and was sent with 5,000 of their soldiers to Baghdad, where he was treated kindly and given pensions along with his chieftains per Baladhuri. The tribute was paid by the Zunbils to amils of caliphs al-Mahdi and ar-Rashid, though rather irregularly. When the Caliph Al-Ma'mun (r. 813–833 AD) visited Khorasan, he was paid double the tribute by Rutbil, but was evidently left unmolested and the Arabs later subdued Kabul. Kabulistan The area of Kabul was initially ruled by the Nezak Huns. Sometime after the defeat of their last king Ghar-ilchi at the hands of Samura, the Turkic Barha Tegin rebelled and assaulted Kabul. Ghar-ilchi was killed and Barha Tegin proceeded to proclaim himself as the king of Kabul, before taking Zabulistan in the south. The "Turk Shahi" dynasty established by him however split into two around 680 AD. The dynasty was Buddhist and were followed by a Hindu dynasty shortly before the Saffarid conquest in 870 AD. Al-Ma'mun's expeditions were the last Arab conflict against Kabul and Zabul and the long-drawn conflict ended with the dissolution of the empire. Muslim missionaries converted many people to Islam; however, the entire population did not convert, with repetitive revolts from the mountain tribes in the Afghan area taking place. The Hindu Shahi dynasty was defeated by Mahmud of Ghazni (r. 998–1030), who expelled them from Gandhara and also encouraged mass-conversions in Afghanistan and India. During the caliphate of Uthman, new popular uprisings had broken out in Persia and continued for five years from 644 to 649. The revolts were suppressed and Abdullah b. Amir, who was appointed governor of Basra, had captured many cities including Balkh, Herat and Kabul. After Muawiyah became the Caliph, he prepared an expedition under 'Abd ar-Rahman b. Samura to Khorasan. Per Baladhuri, after recapturing Zarang as well as conquering other cities, the Arabs besieged Kabul for a few months and finally entered it. Samura concluded a treaty and proceeded to attack Bost, al-Rukhkhaj and Zabulistan. The people of Kabul however rebelled and Samura was forced to recapture the city. The account of Tarjuma-i Futuhat however differs and states that Samura besieged the city for a year. After capturing it, he had all the soldiers massacred and their wives and children taken as captives. He also ordered the captured king Ghar-ilchi to be beheaded, but spared him when he converted. Around the same time according to al-Baladhuri, Al-Muhallab ibn Abi Sufra launched an attack on the Indian frontier, reaching up to Bannu and "al-Ahwaz" (Waihind). The historian Firishta states that while capturing Kabul in 664 AD, Samura had made converts of some 12,000 people. The new king of Kabul Barha Tegin and the Zunbil campaigned against the Arabs after Samura's departure, recapturing Kabul, Zabulistan and al-Rukhkhaj. Rabi b. Ziyad attacked the Zunbil after becoming governor in 671 AD. His successor Ubayd Allah b. Abi Bakra continued the campaign in 673 AD, with the Zunbil negotiating for both Zabul and Kabul soon afterwards. About the time of death of Yazid I however, "the people of Kabul treacherously broke the compact". The Arab army sent to reimpose it was routed. In about 680–683, the kingdom split into two with the Zunbil fleeing from his brother, the king of Kabul, and approaching Salm b. Ziyad at Amul in Khorasan. In return for him agreeing to acknowledge Salm as his overlord, the Zunbil was allowed to settle down in Amul. Soon he drove his brother out and established himself in Amul. The location of Amul mentioned by Tabari is not certain, Josef Markwart identified it with Zabul. Tabari however claims the Kabul Shah fled instead from the Zunbil and established himself as an independent king during the reign of Mu'awiya. Abdur Rehman, who studied the descriptions of Tabari however stated that these events should be seen as having happened in Yazid's time since Salm was governor under his reign. In 152 AH (769 AD), Humayd ibn Qahtaba, the governor of Khorasan, raided Kabul. According to Ibn al-Athir, al-'Abbas b. Ja'far led an expedition against Kabul sent by his father Ja'far b. Muhamamad in 787–78, which Bosworth claims is the one attributed to Ibrahim b. Jibril by Al-Ya'qubi. The only record of an event in early Abbasid period obviously related to the area south of the Hindu Kush, is the expedition against Kabul in 792-793 ordered by Al-Fadl ibn Yahya and led by Ibrahim b. Jibril. It is mentioned by al-Tabari's chronicle, the tenth century Kitāb al-Wuzarā'wa al-Kuttāb of al-Jahshiyari and by al-Ya'qubi. Per al-Jahshiyari, he conquered Kabul and acquired a lot of wealth. Al-Ya'qubi states that rulers and landlords of Tukharistan, including Bamiyan's king, joined this army, implying it crossed the Hindu Kush from the north. It also mentions the subjugation of "Ghurwand" (present-day Ghorband). He also mentions the "Pass of Ghurwand", which judging by the itinerary of the expedition from Tukharistan to Bamiyan to Ghorband valley, is identical to Shibar Pass. They then marched to Shah Bahar where an idol venerated by the locals was destroyed. The inhabitants of various towns then concluded peace treaties with Fadl, one of which was identified by Josef Markwart as Kapisa. Al-Ma'mun (r. 813–833 AD) while visiting Khorasan, launched an attack on Kabul, whose ruler submitted to taxation. The king of Kabul was captured and he then converted to Islam. Per sources, when the Shah submitted to al-Ma'mun, he sent his crown and bejeweled throne, later seen by the Meccan historian al-Azraqi, to the Caliph who praised Fadl for "curbing polytheists, breaking idols, killing the refractory" and refers to his successes against Kabul's king and ispahabad. Other near-contemporary sources however refer to the artifacts as a golden jewel-encrusted idol sitting on a silver throne by the Hindu Shahi ruler or by an unnamed ruler of "Tibet" as a sign of his conversion to Islam. Qutayba's campaigns Qutayba b. Muslim was appointed the governor of Khorasan in 705 by al-Hajjaj b. Yusuf, the governor of Iraq and the East. He began his rule with the reconquest of western Tokharistan in the same year. Qutayba, who was tasked with subduing the revolt in Lower Tokharistan, led the final conquest of Balkh. His army was assembled in spring of 705 and marched to Balkh. Per one version of al-Tabari, the city was surrendered peacefully. Another version, speaks of a revolt among the residents. In 706, he received the submission of Nizak, the leader of Badghis. In 707, he marched on Bukhara oasis along with Nizak in his army but the campaign did not achieve any major objective. According to Baldhuri, when Qutayba became the governor of Khorasan and Sistan, he appointed his brother 'Amr to Sistan. 'Amr asked the Zunbil to pay tribute in cash but he refused, prompting Qutayba to march against him. The campaign was also partially encouraged by his desire to eliminate the support of the southern Hepthalites, the Zabulites, for their northern brethren to revolt. Zunbil, who was surprised by this unexpected move and scared of Qutayba's reputation, quickly capitulated. Qutayba, realizing the real strength of the Zunbils, accepted it and returned to Merv, leaving only an Arab representative in Sistan. Per Al-Mada'ini, Qutayba returned to Merv after conquering Bukhara in 709. The rebellion of the Hepthalite principalities from the region of Guzgan, including Taloqan and Faryab, led Qutayba to dispatch 12,000 men from Merv to Balkh in winter of 709. The rebellion was led and organized by Nezak Tarkhan and was supported by Balkh and Marw al-Rudh's dihqan Bādām. Nizak had realised that independence would not be possible if Arab rule was strengthened in Khorasan, and perhaps was also encouraged by Qutayba's attempts to achieve his objectives through diplomacy. The success of Zunbils may also have encouraged him. Nizak wrote to the Zunblis asking for help. In addition, he also forced the weak Jābghū of Tokharistan to join his cause to persuade all princes of the Principalities of Tukharistan to do the same. His plan to stage the revolt in spring of 710 was however spoilt by Qutayba. Bādām fled when Qutayba advanced on Marw al-Rudh but his two sons were caught and crucified by him. Qutayba next marched to Taloqan, which was the only place in his campaign where the inhabitants were not given a complete amnesty, concerning which H.A.R. Gibb states the "traditions are hopelessly confused". Per one account, he executed and crucified a band of bandits there, though it is possible it was selected for this severity as it was the only place where there was an open revolt. Faryab and Guzgan both submitted and their inhabitants were not harmed. From there, Qutayba went on to receive the submission of people of Balkh. Almost all of Nizak's princely allies had reconciled themselves with Qutayba and there were Arab governors in all towns of Tokharistan, spoiling his plans. He fled south to the Hindu Kush, hoping to reach Kabul and entrenched himself in an inaccessible mountain pass guarded by a fortress. The Arabs succeeded in gaining the fort with help of Ru'b Khan, ruler of Ru'b and Siminjan. Nizak fled along the modern road that leads from the Oxus valley to Salang Pass and holed up in an unidentified mountain refuge in a site of Baghlan Province. Qutayba caught up with him and besieged him for two months. Sulaym al-Nasih (the counsellor), a mawla of Khorasan, helped in obtaining Nizak's surrender to Qutayba who promised a pardon. Nonetheless, he was executed along with 700 of his followers after orders from al-Hajjaj. The Jabghu of Tokharistan was sent as a valuable hostage to Damascus. Qutayba then went in pursuit of Juzjan's king, who requested amnesty and called for exchange of hostages as a precautionary measure. This was agreed upon and Habib b. 'Abd Allah, a Bahilite, was sent as prisoner by Qutayba while the king sent some of his family members in return. The peace treaty was agreed but the king died in Taloqan on his return journey. His subjects accused the Muslims of poisoning him and killed Habib, with Qutayba retaliating by executing Juzjan's hostages. Other regions Ghur Tabari records that in 667 AD, Ziyad b. Abihi had sent Hakam b. 'Amr al-Ghafri to Khorasan as Amir. Hakam raided Ghur and Farawanda, bringing them to submission through force of arms and conquered them. He obtained captives and a large amount of plunder from them. A larger expedition was undertaken under Asad ibn Abdallah al-Qasri, the governor of Khorasan, who raided Gharchistan in 725, receiving its submission as well as the conversion of its king to Islam. He next attacked Ghur whose residents hid their valuables in an inaccessible cave, but he was able to plunder the wealth by lowering his men in crates. Asad's success prompted him to undertake a second expedition in 108-109 AH against Ghur. The poet Thabit Qutna's eulogical poem of Asad recorded by Tabari called it a campaign against the Turks saying, "Groups of the Turks who live between Kabul and Ghurin came to you, since there was no place in which they might find refuge from you." Bosworth states that this campaign may have actually taken place in Guzgan or Bamiyan rather than the purely-Iranian Ghur. He also states that no doubt further sporadic raids continued throughout the Umayyad rule, though not noted by historians. It is known that Nasr ibn Sayyar's commander Sulaiman b. Sul had raided Gharchistan and Ghur some time before 739 AD. The early history of Ghor is unclear. Minhaj-i-Siraj in Tabaqat-i-Nasiri states that Shansab, who established the Ghurid dynasty, was converted by the Arab Caliph Ali which Mohammad Habib and K. A. Nizami dismissed as unlikely. He further adds that the Ghurid Amir Faulad assisted Abu Muslim in overthrowing the Umayyads during the Abbasid Revolution. He also recounts a legend about a dispute between two prominent families of the area. They sought the intercession of the Abbasids and the ancestor of the Shansabi family, Amir Banji, was subsequently confirmed as the ruler by Harun al-Rashid. No permanent control was ever established on Ghur. According to Bosworth, its value was only for its slaves which could best be obtained in occasional temporary raids. Arab and Persian geographers never considered it important. In all sources it is cited as supplying slaves to slave markets in Khorasan, indicating it had a mostly "infidel" population. Istakhari called it a land of infidels (dar al-kufr) annexed to Islamic domain because of its Muslim minority. However Hudud al-'Alam stated it had a mostly-Muslim population. Ghazni The pre-Ghaznavid royal dynasty of Ghazni were the Lawiks. Afghan historian 'Abd al-Hayy Habibi Qandahari, who in 1957 examined a manuscript containing tales about miracles (karamat) of Shaikh Sakhi Surur of Multan, who lived in the 12th century, concluded it dated to 1500. He recorded one of its anecdotes which records the history of Ghazni by the Indian traditionalist and lexicographer Radi ad-Din Hasan b. Muhammad al-Saghani (died 1252) from Abu Hamid az-Zawuli. According to it, a great mosque at Ghazni was earlier a great idol-temple built in honor of the Rutbils and Kabul-Shahs by Wujwir Lawik. His son Khanan converted to Islam and was sent a poem by the Kabul-Shah saying, "Alas! The idol of Lawik has been interred beneath the earth of Ghazni, and the Lawiyan family have given away [the embodiment of] their kingly power. I am going to send my own army; do not yourself follow the same way of the Arabs [ie., Islam]." Habibi continues stating that Khanan later reconverted to the faith of the Hindu-Shahis. His grandson Aflah however upon assuming power demolished the idol-temple and built a mosque in its place. When the saint Surur arrived at the mosque, he is said to have found the idol of Lawik and destroyed it. The Siyasatnama of Nizam al-Mulk, the Tabaqat-i Nasiri of Juzjani and the Majma' al-ansāb fī't-tawārīkh of Muhammad Shabankara'i (14th century) mention Lawik. Juzjani gives the Lawik who was defeated by Alp-tegin the Islamic kunya of Abu Bakr, though Shabankara'i claims he was a pagan. A variant of his name appears as Anuk in Tabaqat-i Nasiri. Bamyan Ya'qubi states that the lord of Bamyan called the Shēr, was converted to Islam under Caliph Al-Mansur (d.775) by Muzahim b. Bistam, who married his son Abu Harb Muhammad to his daughter. However, in his history he changes it to the rule of Al-Mahdi (r. 775–785). Ya'qubi also states that Al-Fadl ibn Yahya made Hasn, Abu Harb Muhammad's son, as the new Shēr after his successful campaign in Ghorband. Ya'qubi states that the ruler of Bamiyan had accompanied an expedition dispatched by Al-Fadl ibn Yahya in 792–793 against the Kabul Shahi. Later Shers remained Muslim and were influential at the Abbasid court. However, Muslim sources describe the Saffarid ruler Ya'qub ibn al-Layth al-Saffar looting Bamiyan's pagan idols. A much later historian Shabankara'i claims that Alp-Tegin obtained conversion of the Sher to Islam in 962. It seems there were lapses to Buddhism among some of the rulers as the Muslim influence grew weak. However, there is no evidence about the role of Buddhism during these periods or whether Buddhist monasteries remained the center of religious life and teaching. Post-Arab rule Tahirids Khurasan was the base for early recruitment of Abbasid armies, especially the Abbasid takeover received support from Arab settlers aiming to undermine the important sections of non-Muslim aristocracy. The Abbasids succeeded in integrating Khorasan and the East into the central Islamic lands. The state was gradually Persianized through political influence and financial support of the dihqans. Al-Ma'mun emerged as the victor in the Fourth Fitna with the help of Khorasani forces and appointed Tahir ibn Husayn as the governor. Later, he appointed Talha as the governor in 822 and Abdallah in 828. But after the Abbasid decline, Khorasan ended up turning into a virtually independent state under a Persian mawla who rose to favour under Al-Ma'mun. According to Ibn Khordadbeh, the Shah of Kabul had to send 2,000 Oghuz slaves worth 600,000 dirhams as annual tribute to the governor of Khorasan Abdallah ibn Tahir (r. 828-845). In addition to the Oghuz slaves, he also had to pay an annual tribute of 1.5 million dirhams. Mid-9th century, one of their tributaries Abu Da'udid or the Banijurid Amir Da'ud b. Abu Da'ud Abbas, undertook an obscure campaign into eastern Afghanistan and Zabulistan that was profitable. It is recorded that in 864 Muhammad ibn Tahir sent two elephants captured at Kabul, idols and aromatic substances to the caliph. Saffarids Ya'qub b. al-Layth The Tahirid rule was overthrown by Ya'qub ibn al-Layth al-Saffar of Sistan, the first independent Iranian ruler in the post-Islamic era. He also fought against the Abbasid Caliphate. He joined the 'ayyar band of Salih b. al-Nadr/Nasr, who was recognised as Bust's amir in 852. al-Nasr aimed at taking over whole of Sistan and drove out the Tahirid governor in 854, with Sistan ceasing to be under the direct control of the Caliphate. al-Nasr himself was overthrown by Dirham b. Nasr who was overthrown by Ya'qub in 861. Ya'qub and his brother Amr advanced as far as Baghdad and to Kabul itself in eastern Afghanistan with their dynamism, advancing along the historic route taken by the modern Lashkargah-Qandahar-Ghazni-Kabul road. Their eastern campaigns are documented by Arabic sources of Al-Masudi's Murūj adh-dhahab, Ibn al-Athir's al-Kāmil fi't-tā'rīkh and Tarikh-e-Sistan. The Persian historian Gardizi's Zain al-akhbār also mentions the Saffarid campaigns. Salih fled to ar-Rukhkhaj or Arachosia, where he received the help of the Zunbil. Both Salih and the Zunbil were killed by Ya'qub in 865. Abu Sa'id Gardezi mentions that Ya'qub advanced from Sistan to Bust and occupied the city. From here he advanced to Panjway and Tiginabad (two of the chief towns of Arachosia), defeating and killing the Zunbil, though the date is not given. This account matches with that of Tarikh-e-Sistan. Satish Chandra states that, "We are told that it was only in 870 AD that Zabulistan was finally conquered by one Yakub who was the virtual ruler of the neighbouring Iranian province of Siestan. The king was killed and his subjects were made Muslims." Muhammad Aufi's Jawami ul-Hikayat meanwhile states that during his invasion of Zabul, Yaqub employed a ruse to surrender after being allowed to pay homage to the ruler along with his troops, lest they disperse and become dangerous to both sides. Yaqub's troops "carried their lances concealed behind their horses and were wearing coats of mail under their garments. The Almighty made the army of Rusal (probably Rutbil), blind, so that they did not see the lances. When Yaqub drew near Rusal, he bowed his head as if to do homage, but raised a lance and thrust it in the back of Rusal so that he died on the spot. His people also fell like lightning upon the enemy, cutting them down with their swords and staining the earth with the blood of the enemies of the religion. The infidels when they saw the head of Rusal upon the point of a spear took to flight and great bloodshed ensued. This victory, which he achieved, was the result of treachery and deception, such as no one had ever committed." Ashirbadi Lal Srivastava states that after this victory by Yaqub over Zabul, the position of Lallya alias Kallar, the Brahmin minister who had overthrown the last Kshatriya king of Kabul Lagaturman, seems to have become untenable. He shifted his capital to Udhaband in 870 AD Lallya, credited as an able and strong ruler by Kalhana in Rajatarangini, was driven out by Ya'qub from Kabul within a year of his usurpation according to Srivastava. Gardezi states that after defeating the Zunbil, Yaqub then advanced into Zabulistan and then Ghazni, whose citadel he destroyed and forced Abu Mansur Aflah b. Muhammad b. Khaqan, the local ruler of nearby Gardez, to tributary status. Tarikh-e-Sistan however in contrast states that he returned to Zarang after killing Salih. This campaign may be related to Gardizi's account of a later expedition in 870 where he advanced as far as Bamiyan and Kabul. Salih b. al-Hujr, described as a cousin of the Zunbil, was appointed as the Saffarid governor of ar-Rukhkhaj, but rebelled two years after Zunbil's death and committed suicide to avoid capture. Ya'qub had captured several relatives of the Zunbil's family after defeating Salih b. al-Nasr. Zunbil's son escaped from captivity in 869 and quickly raised an army in al-Rukhkhaj, later seeking refuge with the Kabul-Shah. Per Gardizi, Ya'qub undertook another expedition in 870 which advanced as far as Kabul and Bamiyan. According to Tarikh-e-Sistan, Bamiyan was captured in 871 and its idol-temple was plundered. Ya'qub defeated Kabul in 870 and again had to march there in 872 when the Zunbil's son took possession of Zabulistan. Ya'qub captured him from the fortress of Nay-Laman where he had fled. In 871, Ya'qub sent 50 gold and silver idols he gained by campaigning from Kabul to Caliph Al-Mu'tamid, who sent them to Mecca. According to Tabaqat-i-Nasiri, Ghor, which was ruled by Amir Suri in the 9th century, entered into a war against Ya'qub, but escaped conquest due to its difficult and mountainous terrain. Amr b. al-Layth After Ya'qub's death in 879, Al-Mu'tamid recognised his brother and successor 'Amr b. al-Layth (r. 879–902), as governor of Khorasan, Isfahan, Fars, Sistan and Sindh. The caliph however announced divesting him of all his governorships in 885 and reappointed Muhammad b. Tahir as the governor of Khorasan. He was reappointed governor of Khorasan in 892 by Al-Mu'tadid. Amr led an expedition as far as Sakawand in the Logar Valley, between Ghazni and Kabul, described as a Hindu pilgrimage-centre. In 896, he sent idols captured from Zamindawar and the Indian frontier, including a female copper idol with four arms and two girdles of silver set with jewels and pulled on a trolley by camels, to Baghdad. Al-Baihaki mentions Sakawand as a pass from Kabul to India. It was situated at or near Jalalabad. The idol taken from somewhere in eastern Afghanistan by Amr was displayed for three days in Basra and then for three days in Baghdad. Jamal J. Elias states that it may have been of Lakshmi or Sukhavati at Sakawand. Al-Masudi emphasises the attention it received as a spectacle, with crowds gathering to gawk at it. Aufi states that Amr had sent Fardaghan as the prefect over Ghazni and he launched the raid on Sakawand, which was a part of the territory of Kabul Shahi and had a temple frequented by Hindus. The Shah of Kabul at this time was Kamaluka, called "Kamalu" in Persian literature. Fardaghan entered it and succeeded in surprising Sakawand. Sakawand was plundered, and its temple destroyed. Kamalu counter-attacked Fardaghan, who realising his forces were no match for his, resorted to spreading a false rumour that he knew his intentions and had organised a formidable army against him with 'Amr on the way to join him. The rumour had the desired effect and the opposing army slowed its advance, knowing that they could be ambushed and slaughtered if they advanced impetuously into the narrow defiles. Meanwhile, Fardaghan received reinforcements from Khorasan according to Aufi. According to Aufi, he cleverly averted the danger. Tarikh-e-Sistan does not mention any attack by Fardaghan on Sakawand however, instead beginning with the attack by Kamalu. Per it, when Amr was in Gurgan, he heard that Nasad Hindi and Alaman Hindi had allied and invaded Ghazni. The Saffarid governor 'Fard 'Ali was defeated and fled. Samanids The Samanids came to rule over areas including Khorasan, Sistan, Tokharistan and Kabulistan after Ismail (r. 892–907) in 900 AD had defeated the Saffarids, who had taken over Zabulistan and the Kabul region. The Turks were highly noted for their martial prowess by the Muslim sources and were in high demand as slave-soldiers (ghulam, mamluk) by the Caliphate in Baghdad and the provincial emirs. The slaves were acquired either in military campaigns or through trade. The Samanids were heavily involved in this trade of Turkish slaves from lands to the north and east of their state. As the enslavement was limited to non-Muslims and with the Turks increasingly adopting Islam beyond Samanid borders, they also entered Transoxiana as free men due to various causes. The Ghaznavids arose indirectly from the atmosphere of disintegration, palace revolutions and succession putschs of the Samanid Empire. Abu-Mansur Sabuktigin was one of the Samanid slave guards who rose from the ranks to come under the patronage of the Chief Hajib Alp-Tegin. After the death of the Samanid Amir 'Abd al-Malik b. Nuh, the commander of forces in Khorasan Alp-Tegin along with the vizier Muhammad Bal'ami attempted to place a ruler of their choice on the throne. The attempt failed however and Alp-Tegin decided to withdraw to the eastern fringes of the empire. Per the sources, he wanted to flee to India to avoid his enemies and earn divine merit by raiding the Hindus. He did not intend to capture Ghazni, but was forced to take it when he was denied transit by its ruler. Alp-Tegin proceeded with his small force of ghulams and ghazis (200 ghulams and 800 ghazis according to Siyasatnama, while Majma al-ansab of Muhammad b. Ali al-Shabankara'i (d. 1358) states 700 ghulams and 2,500 Tajiks). En route, he subdued the Iranian Sher of Bamiyan and the Hindu-Shahi king of Kabul. He then came to Ghazni, whose citadel he besieged for four months and wrested the town from its ruler, Abu 'Ali or Abu Bakr Lawik or Anuk. The origin of this chief was Turkic, though it is not known if he was a Samanid vassal or an independent ruler. Josef Markwart suggests he was a late representative of the Zunbils. The Lawik dynasty of Ghazni was linked to the Hindu Shahi dynasty through marriage. Alp-Tegin was accompanied by Sabuktigin during the conquest of Ghazni. Minhaj al-Siraj Juzjani states that Alp-Tegin had his position regularised by Amir Mansur b. Nuh through an investiture, however Siyasatnama mentions an expedition against Alp-Tegin from Bukhara which was defeated outside Ghazni. His ambiguous, semi-rebel status seems to be reflected in his coins, with two of his coins minted at Parwan mentioning his authority from the Samanids to mint coins only in an indirect way. He was succeeded by his son Abu Ishaq Ibrahim, who lost Ghazni to Abu Ali Lawik, the son of its expelled ruler. He recovered it however with Samanid help in 964–65. Alp-Tegin's ghulams were reconciled with the Samanids in 965 but maintained their autonomy. After Ibrahim's death in 966, Bilge-Tigin was made the successor and he acknowledged the Samanids as his overlords. He died in 364 AH (974–975 AD) while besieging Gardez and was succeeded by Böritigin or Piri. Piri's misrule led to resentment among the people who invited Abu Ali to take back the throne. The Kabul Shahis allied with him and the king, most likely Jayapala, sent his son to assist Lawik in the invasion. According to the Majba al-Ansab, Sabuktigin managed to convince the Muslim Turks living in Ghazni, Gardez and Bamyan to participate in a jihad against the Hindus. When the allied forces reached near Charkh on Logar River, they were attacked by Sabuktigin who killed and captured many of them, while also capturing ten elephants. Lawik as well his ally were both killed in the battle. Piri was expelled and Sabuktigin became governor in 977 AD. The accession was endorsed by the Samanid ruler Nuh II. Hudud al-‘Alam states that Ghor was under the overlordship of Farighunids. Both Gardezi and Baihaqi state that in 379 AH (979–980 AD), the Samanid Amir Nuh b. Mansur dispatched an expedition under Abu Ja'far Zubaidi to conquer Ghur, but he had to return after capturing several forts. As the Samanid governor of Zabulistan and Ghazni, Sabuktigin attacked it several times. He was able to conquer eastern Ghur after initial set-backs and was acknowledged as a sovereign by Muhammad ibn Suri. Ghaznavids Sabuktigin First war against Jayapala The Ghaznavid campaigns from the time of Sabuktigin are recorded as jihad against the people of al-Hind to destroy idolatry and replace it by expanding Islam. The Kabul Shahis only retained Lamghan in the Kabul-Gandhara area by the time of Alp-Tegin. According to Firishta, Sabuktigin had already begun raiding Multan and Lamghan under Alp-Tegin for slaves. This precipitated an alliance between the Shahi ruler Jayapala, Bhatiya and Sheikh Hamid Khan Lodi. He crossed the Khyber Pass many times and raided the territory of Jaipala. Jayapala appointed Sheikh Hamid Khan Lodi as ruler over Multan and Lamghan, but Sabuktigin broke up this alliance after his accession through diplomatic means, convincing Lodi to acknowledge him as an overlord. Although Ferishta had identified Lodi and his family as Afghans, historian Yogendra Mishra pointed out that this was an error, since they were descended from the Qurayshite Usama ibn Lawi ibn Ghalib. Sabuktigin plundered the forts in the outlying provinces of the Kabul Shahi and captured many cities, acquiring huge booty. He also established Islam at many places. Jaipal in retaliation marched with a large force into the valley of Lamghan (Jalalabad) where he clashed with Sabuktigin and his son. The battle stretched on several days until a snow storm affected Jaipala's strategies, forcing him to plead for peace. Sabuktigin was inclined to grant peace to Jayapala but his son Mahmud wanted total victory. Jaypala upon hearing Mahmud's plans warned Sabuktigin, "You have seen the impetuosity of the Hindus and their indifference to death... If therefore, you refuse to grant peace in the hope of obtaining plunder, tribute, elephants and prisoners, then there is no alternative for us but to mount the horse of stern determination, destroy our property, take out the eyes of our elephants, cast our children into fire, and rush out on each other with sword and spear, so that all that will be left to you to conquer and seize is stones and dirt, dead bodies, and scattered bones." Knowing Jaipala could carry out his threat, Sabuktigin granted him peace in return for his promise of paying tribute and ceding some of his territory. Second war against Jayapala After making peace with Sabuktigin, Jayapala returned to Waihind but broke the treaty and mistreated the amirs sent to collect the tribute. Sabuktigin launched another invasion in retaliation. While the mamluks remained the core of his army, he also hired the Afghans, especially the Ghilji tribe, in his dominion. According to al-Utbi, Sabuktigin attacked Lamghan, conquering it and burning the residences of the "infidels", while also demolishing its idol-temples and establishing Islam. He proceeded to slaughter the non-Muslims, destroyed their temples and plundered their shrines. It is said that his forces even risked frostbite on their hands while counting the large booty. To avenge the savage attack of Sabuktigin, Jayapala, who had earlier taken his envoys as hostage, decided to go to war again in revenge. According to al-Utbi, he assembled an army of 100,000 against Sabuktigin. The much later account of Ferishta states that it included troops from Kanauj, Ajmer, Delhi and Kalinjar. The two sides fought on an open battlefield in Laghman. Sabuktigin divided his army into packs of 500 who attacked the Indians in succession. After sensing that they were weakened, his forces mounted a concerted attack. The forces of Kabul Shahi were routed and those still alive were killed in the forest or drowned in the river. The second battle that took place between Sabuktigin and Jayapala in 988 AD, resulted in the former capturing territory between Lamghan and Peshawar. Al-Utbi also states that the Afghans and Khaljis, living there as nomads, took the oath of allegiance to him and were recruited into his army. He helped Nuh II in expelling the rebel and heretic Abu Ali Simjur from Khorasan, resulting in its governorship being given to Sabuktigin who appointed Mahmud as his deputy there. He also appointed Ismail as the successor to his kingdom and died in 997. A succession war erupted between Ismail and Mahmud, with the latter gaining the throne in 998. Mahmud The Samanid amir Mansur II appointed Bektuzun as Khorasan's governor after Sabuktigin's death. Mahmud however wished to reacquire the governorship after defeating his brother Ismail and his allies. Bektuzun and Fa'iq, the de facto power behind the Samanid throne, toppled Mansur II as they did not trust him, and replaced him with Abu'l Fawaris 'Abd al-Malik. Their forces were however defeated in 999 by Mahmud, who acquired all the lands south of Oxus, with even those to the north of the river submitting to him. The Samanid dynasty was later ended by the Karakhanids. In 1002, Mahmud also defeated the Saffarid Amir Khalaf ibn Ahmad and annexed Sistan. Wars against Kabul Shahi Mahmud systemized plunder raids into India as a long-term policy of the Ghaznavids. The first raid was undertaken in September 1000, but was meant for reconnaissance and identifying the possible terrain and roads that could be used for future raids. He reached Peshawar by September 1001 and was attacked by Jayapala. The two sides clashed on 27–28 November 1001 and Jayapala was captured. Anandapala who was at Waihind, had to pay a heavy ransom to have his father and others released. Jayapala later self-immolated out of shame and Anandpala succeeded him. Mahmud attacked Anandpala later over his refusal to allow him passage during his attack on Multan, which was controlled by Fateh Daud. The two sides clashed in 1009 in the eastern side of Indus at Chhachh, with Mahmud defeating Anandapala and capturing the fort of Bhimnagar. He was allowed to rule as a feudatory in Punjab for some time. An alliance between Anandpala's son, Trilochanpala, and Kashmiri troops was later defeated. During the warfare from 990–91 to 1015, Afghanistan, and later Punjab and Multan were lost to the Ghaznavids. Trilochanpala's rule was limited to eastern Punjab and he gained respite from the Muslim invasions with retreat to Sirhind. He allied with the Chandellas and in 1020-21 was defeated at a river called Rahib by Al-Utbi, while Firishta and Nizamuddin Ahmad identify it as Yamuna. He was killed in 1021 AD by his mutinous troops and succeeded by Bhimapala, who became the last ruler of the Kabul Shahi and was killed fighting the Ghaznavids in 1026 AD. The remnants of the royal family sought refuge with the Lohara dynasty of Kashmir and Punjab passed under the control of Muslim conquerors. Mahmud used his plundered wealth to finance his armies which included mercenaries. The Indian soldiers, presumably Hindus, who were one of the components of the army, with their commander called sipahsalar-i-Hinduwan, lived in their quarter of Ghazni while practicing their own religion. Indian soldiers under their commander Suvendhray remained loyal to Mahmud. They were also used against a Turkic rebel, with the command given to a Hindu named Tilak according to Baihaki. The renowned 14th-century Moroccan Muslim scholar Ibn Battuta remarked that the Hindu Kush meant the "slayer of Indians", because the slaves brought from India who had to pass through there died in large numbers due to the extreme cold and quantity of snow. He states: Invasions of Ghur The conversion of Ghur occurred over a long period and it was mostly pagan until the 10th century, which Mohammad Habib and Khaliq Ahmad Nizami say was probably a result of the missionary activities by the Karramiyya movement established in the region in 10th–11th centuries. Its imperfect conversion is visible by the fact that while the people of Ghur had Muslim names, they led the life of pagans. Muhammad b. Suri, who had acknowledged Sabuktigin as his sovereign, withheld tribute after his death, started plundering caravans and harassed the subjects of Mahmud. Rawżat aṣ-ṣafāʾ called him a pagan, and al-Utbi stated that he was a Hindu. In 1011, Mahmud dispatched an expedition to conquer Ghur under Altuntash, governor of Herat, and Arslan Hajib, governor of Tus. Muhammad b. Suri, the king, placed himself in inaccessible hills and ravines. The Ghurids were however defeated and Suri was captured along with his son Shith. Abu Ali, who had remained on good terms with the Sultan, was made the ruler of Ghur by him. Eastern Ghur was brought under Ghaznavid control. In 1015, Mahmud attacked Ghur's southwestern district of Khwabin and captured some forts. In 1020, Mahmud's son Ma'sud was dispatched to take Ghur's northwestern part called Tab. He was helped by Abul Hasan Khalaf and Shirwan, chieftains of the south-western and north-eastern regions respectively. He captured many forts, bringing the entire region of Ghur, except maybe the inaccessible interior, under Ghaznavid control. He also captured the stronghold of the chieftain Warmesh-Pat of Jurwas, levying a tribute of arms. Minhaj al-Siraj Juzjani praises Abu Ali for firmly establishing Islamic institutions in Ghur. The progress of Islam in this divided region after his death is however unknown. Ghur remained a pagan enclave until the 11th century. Mahmud who raided it, left Muslim precepts to teach Islam to the local population. The region became Muslim by 12th century, though the historian Satish Chandra states that Mahayana Buddhism is believed to have existed until the end of the century. Neither Mahmud nor Ma'sud conquered the interior. Habib and Nizami say that the Ghurids were gradually converted by propagandists of new mystic movements. The Shansabani eventually succeeded in establishing their seniority in Ghor, if not its unification. By the time of Sultan Bahram, Ghur was converted and politically unified. According to Minhaj, both Ghiyasuddin and Mu'izzuddin were Karamis who later converted to Shafi‘i and Hanafi Islam respectively. Tarikh-i guzida however says that the Ghorids were only converted to Islam by Mahmud. Conversion of Pashtun-Afghan people The name Afghanistan was first used in a political sense by Saifi Herawi in the 14th century. It was even used during the height of the Durrani Empire. Only after the Durand line was fixed, did its modern usage for the land between it and the Oxus river become usual. The people who were mostly responsible for establishing the Afghan kingdom are referred to as Pashtun, who were also called "Afghans". The name Pashtun (or Pakthun) is the original and oldest name. The tenth-century Persian geography Hudud al-'Alam is the earliest known mention of the Afghans. In Discourse on the Country of Hindistan and Its Towns, he states that, "Saul, a pleasant village on a mountain. In it live Afghans." Ibn Battuta described Saul as being situated between Gardez and Husaynan along a common trade route, the exact location of Husaynan is unknown. Akhund Darweza states that their original homeland was Qandahar from where they migrated in 11th century upon the request of Mahmud of Ghazni to assist him in his conquests. Afghan tradition considers "Kase Ghar" in Sulayman range as the homeland. Hudud al-'Alam also mentions that the king of Ninhar (Nangarhar) had many wives including "Moslem, Afghan and Hindu". The Pashtun traditions speak of Islamization during Muhammad's time through Khalid ibn Walid. Qais Abdur Rashid, the presumed ancestor of the Afghans, is said to have led a delegation to Mecca from Ghor after being summoned by Khalid b. Walid and converted to Islam while also distinguishing himself in the service of Muhammad. He adopted the name Abdul Rashid, and his three sons – Saraban, Ghurghust, Karlani, and a foundling Karlanri linked to Saban, are considered to be the progenitors of the major Afghan divisions. Ni'matullah's Makhzan-i-Afghani traces their history to an Israelite called Afghana who constructed the al-Aqsa mosque. Per it, under the time of King Suleiman, a figure named Bokhtnasser was responsible for "carrying away the Israelites, whom he settled in the mountainous districts of Ghor, Ghazneen, Kabul, Candahar, Koh Firozeh, and the parts lying within the fifth and sixth climates; where they, especially those descended of Asif and Afghana, fixed their habitations, continually increasing in number, and incessantly making war on the infidels around them." Qais traveled to Medina to receive Mohammed's blessings and fought against the Meccans. Muhammad himself conferred the title of Pashtun upon Qais and his people according to the tradition. They returned to Ghor to spread Islam and pledged loyalty to Mahmud. Per Ni'matullah, the Ghurid ruler Mu'izz al-Din had initiated their eastward migration into present-day north-west Pakistan, in course of his military campaigns. The Arabs, at war with the Kabul Shah, had directed their campaigns in direction of Gandhara. By the time of Muawiya, Sistan's governorship was separated from Khorasan, with the governor looking after the region and keeping a check on Kabul Shah. Ahmed Hassan Dani considers that the Arab activities may have led to conversion of Aghans as well, and it may have been wholesale because of their tribal nature, i.e., all the Afghan tribes adopted Islam at once. Quoting Matla-al-Anwar, Ferishta states that a man named Khalid, son of Abdullah, stated by some to be a descendant of Khalid bin Walid or Abu Jahl, was for some time governor of Herat, Ghor, Gharjistan and Kabul. After being relieved of the charge, he settled in Koh Sulaiman, with the Lodis and Suris being the descendant of his daughter who married a converted Afghan. Al-Utbi in Tarikh-i-Yamini states that the Afghans were enlisted by Sabuktigin and also Mahmud. During this period, the Afghan habitat was in the Sulaiman Mountains. After defeating Jayapala in 988 AD, Sabuktigin had acquired the territory between Laghman and Peshawar. Al-Utbi states that the Afghans and Khaljis, living there as nomads, took the oath of allegiance to him and were recruited into his army. Iqtidar Husain Siddiqui citing a 13th-century Persian translation, claims he mentions the "Afghans" were pagans given to rapine and rapacity, they were defeated and converted to Islam. Writing in the 11th century AD, Al-Biruni in his Tarikh al Hind stated that the Afghan tribes lived in mountains west of India. He notes, "In the western frontier mountains of India there live various tribes of the Afghans and extend up to the neighbourhood of the Sindu valley." He earlier also noted about the mountains, "In marching from our country to Sindh we start from the country of Nimroz, i.e. the country of Sijistan, whilst marching to Hind or India proper we start from the side of Kabul... In the mountains which form the frontier of India towards the west there are tribes of the Hindus, or of people near akin to them — rebellious savage races — which extend as far as the farthermost frontiers of the Hindu race." Mahmud had gone to war against pagan Afghan while campaigning in the Sulayman mountains. Firishta states that Afghans fought on both sides during the war between Mu'izz al-Din and Pithorai in 1192 AD, which Encyclopaedia of Islam says probably indicates that they were not completely converted yet. In 1519, Babur mounted an attack on the fort of Bajaur and sent a Dilazak Afghan as an ambassador to the Gibri Sultan of Bajaur, Mir Haidar 'Ali, to surrender and enter his services. Gibri, a Dardic language of Bajaur, was also spoken by the royal family and nobility of the Swat Valley. The Gibris decided to resist and Babur's forces stormed it in two days. He ordered a general massacre of its inhabitants on the pretext that they had rebelled against Kabul's regime and were infidels who had forsaken Islam. The westward migration of Pashtuns from Sulaiman mountains to Qandahar and Herat is thought to have begun in the 15th century. In the 16th century, the area around Qandahar formed a bone of contention between the Ghilzais and Abdalis. The latter gave in and migrated to Herat during the reign of Safavid Shah Abbas I. Their migration displaced or subjugated the indigenous populations, especially the Tajiks who were also the dominant population in Kabul, Nangarhar and Laghman in east Afghanistan. Before the advent of Ghilzais of the Ahmadzai division in the late 16th century, Logar River was also a Tajik stronghold. The Pashtuns also displaced the original Kafirs and Pashayi people in Kunar Valley and Laghman Valley, located south of Kabul in east Afghanistan, to the infertile mountains. Regions to the south and east of Ghazni were the strongholds of Hazaras before the 16th century. They also lost Wardak to the tribe of the same name when the latter invaded in the 17th century. In Qandahar, the Farsiwanis, Hazaras, Kakars and Baloch people were subjugated. Conquests of Kafiristan Kafiristan is a mountainous region of the Hindu Kush that was isolated and politically independent until the Afghan conquest of 1896. Before their conversion to Islam, the Nuristanis or Kafir people practiced a form of ancient Hinduism infused with locally developed accretions. Kafiristan proper from west to east comprises basins of Alishang, Alingar, Pech or Prasun, Waigal and Bashgal. The region became a refuge of an old group of Indo-European people, probably mixed with an older substratum, as well as a refuge of a distinct Kafiri group of Indo-Iranian languages, forming part of the wider Dardic languages. The inhabitants were known as "kafirs" due to their enduring paganism, while other regions around them became Muslim. However, the influence from district names in Kafiristan of Katwar or Kator and the ethnic name Kati has also been suggested. The Kafirs were divided into Siyah-Posh, comprising five sub-tribes who spoke the Kamkata-vari language; while the others were called Safed-Posh, comprising Prasungeli, Waigeli, Wamai and Ashkun. The Kafirs called themselves "Balor", a term that appeared in Chinese sources as early as the fifth century AD. In both the Chinese sources and Muslim sources like the 16th-century work of Kashmir's conqueror Mirza Muhammad Haidar Dughlat, the terms "Bolor" and "Boloristan" denote the area from the Kabul valley to Kashmir, Yarkand and Kashgar. The country is the most inaccessible part of Hindu Kush. The Muslim conquerors could not achieve a lasting success here. The vast area extending from modern Nuristan to Kashmir (styled "Peristan" by A. M. Cacopardo) contained a host of "Kafir" cultures and Indo-European languages that became Islamized over a long period. Earlier, it was surrounded by Buddhist areas. The Islamization of the nearby Badakhshan began in the 8th century and Peristan was completely surrounded by Muslim states in the 16th century with the Islamization of Baltistan. The Buddhist states temporarily brought literacy and state rule into the region. The decline of Buddhism resulted in it becoming heavily isolated. There have been varying theories about the origins of the Kafirs. Oral traditions of some Nuristanis place themselves to be at confluence of Kabul and Kunar River a millennium ago, being driven off from Kandahar to Kabul to Kapisa to Kama with the Muslim invasion. They identify themselves as late arrivals here, being driven by Mahmud of Ghazni, who after establishing his empire, forced the unsubmissive population to flee. George Scott Robertson considered them to be part of the old Indian population of Eastern Afghanistan and stated that they fled to the mountains while refusing to convert to Islam after the Muslim invasion in the 10th century. The name Kator was used by Lagaturman, the last king of the Turk Shahi. The title "Shah Kator" was assumed by Chitral's ruler Mohtaram Shah who assumed it upon being impressed by the majesty of the erstwhile pagan rulers of Chitral. The theory of Kators being related to the Turki Shahis is based on the information of Jami- ut-Tawarikh and Tarikh-i-Binakiti. The region was also named after its ruling elite. The royal usage may be the origin behind the name of Kator. Mahmud of Ghazni In 1020–21, Mahmud of Ghazni led a campaign against Kafiristan and the people of the "pleasant valleys of Nur and Qirat" according to Gardizi. The Persian chronicles speak of Qirat and Nur (or Nardin), which H. M. Elliot on authority of Al-Biruni identifies with Nur and Kira tributaries of Kabul river. Ferishta wrongly calls these two valleys as "Nardin" and Qirat and confuses this conquest with the one against "Nardin" or Nandana. He also wrongly mentions that it took place after 412 AH. Alexander Cunningham identifies the places conquered as "Bairath" and "Narayanpura". These people worshipped the lion. While Clifford Edmund Bosworth considers that Mahmud attacked "pagan Afghans", Joseph Theodore Arlinghaus of Duke University does not consider it correct because his source Gardezi simply calls them "pagan (kafiran)" and not "pagan Afghans", as they were not known to be pagan or live on borders of Nuristan in the 11th century. Mohammad Habib however considers that they might have been worshipping Buddha in the form of a lion (Sakya Sinha). Ramesh Chandra Majumdar states that they had a Hindu temple which was destroyed by Mahmud's general. Ram Sharan Sharma meanwhile states that they may have been Buddhist. Cunningham claims based on the reporting of Ferishta that the place was plundered by 'Amir Ali after being taken. According to Gardezi, while returning from his recent invasion of India, Mahmud had heard about the Kafirs and the chief of Qirat surrendered without any struggle and accepted to convert, with the inhabitants converting as well. Nur however refused to surrender and his general 'Amir Ali led an attack on it, forcing its people to convert. According to Firshta, the rulers of both of them submitted and accepted Islam in 1022. He adds, "On breaking a great temple situated there, the ornamented figure of a lion came out of it, which according to the belief of the Hindus was four thousand years old." However, no permanent conquest was attempted. Iqbal namah-i-Jahangiri stated that Kafirs still lived in Darrah-i-Nur which Mahmud of Ghazni had claimed to have converted. The Mughal Emperor Jahangir had received a delegation of these pure Kafirs in Jalalabad and had honoured them with gifts. Timurids The campaigns of Timur are recorded by Zafarnama, written by Sharaf ad-Din Ali Yazdi, which is based on another work. On his way to India, Timur attacked the Siyah-Posh in 1398 AD after receiving complaints from the trading city of Andarab about the raids by the Kafirs. He penetrated Kafiristan from Khawak pass and restored an old fortress there. He personally proceeded against the Kator region, which extended from Kabul to Kashmir. Timur sent a detachment of 10,000 soldiers against the Siyah-Poshas under Burhan Aglan and had the fort of Kator deserted by Kafirs destroyed, while the houses of the city were burnt. The Kafirs took refuge on top of a hill and many were killed in the ensuing clash. Some held out for three days but agreed to convert after Timur offered them the choice between death and Islam. They however soon apostatised and ambushed Muslim soldiers in the night. They Muslims repelled them and a number of the Kafirs were killed, with 150 being taken prisoner and later executed. Timur ordered his men "to kill all the men, to make prisoners of women and children, and to plunder and lay waste all their property." His soldiers carried out the order and he directed them to build a tower of skulls of the dead Kafirs. Timur had his expedition engraved on a neighbouring hill in the month of Ramadan. His detachment sent against the Siyah-Poshas however met with disaster, with Aglan being routed and forced to flee. A small detachment of 400 men under Muhammad Azad was then sent and defeated the Kafirs, retrieving the horses and armour Aglan lost. Timur later captured a few more places, though nothing more is stated, presumably he left the Siyah-Poshas alone. He proceeded to exterminate the rebellious Afghan tribes and crossed the Indus River in September 1398. The Timurid Sultan Mahmud Mirza is said to have raided Kafiristan twice by Baburnama, which earned him the title of ghazi. Yarkand Khanate Mirza Muhammad Haidar Dughlat invaded Balor under orders of Sultan Said Khan in 1527-1528 AD, and was accompanied by Said's eldest son Rashid Khan. The expedition was an Islamic frontier raid called ghaza. Dughlat undertook highly devastating plundering raids against the region. Rashid Khan (r. 1533–1569) undertook further expeditions against Bolor (Kafiristan), which are recorded by Tarikh-i-Kashgar and Bahr al-asar of Mahmud b. Amir Wali. The Kashgari author mentions it briefly, though Wali goes into detail. The first campaign failed with a number of Kashgari captured and enslaved by the people of Bolor. A second invasion was successful and forced them to submit. Tarikh-i-Kashgar states that Bolor was governed by Shah Babur after Abdullah Khan's successful campaign in 1640. Mughals Babur himself came to the region in the winter of 1507–1508 and had an inscription carved commemorating his transit. While fleeing to India to take refuge in the Afghan-Indian borderlands after Shibani Khan attacked Qandahar, which Babur had recently conquered, he marched from Kabul to Lamghan in September 1507. He eventually reached the Adinapur fort in Nangarhar district and commented that his men had to forage for food and raided the rice fields of the Kafirs in the Alishang district. While writing in his memoirs, Babur noted ​that when he captured Chigha Sarai in 1514, the "Kafirs of Pech came to their assistance." He mentions some Muslim nīmčas or half-breeds, probably converted Kafirs, who married with the Kafirs and lived at Chigha Sarai, located at confluence of Kunar River and Pech River. In 1520, he mentions sending Haidar Alamdar to the Kafirs, who returned and met him under Bandpakht along with some Kafir chiefs who gifted him some wineskins. The relationship between the Siahposh and the residents of Panjshir and Andarab remained the same even more than a century after Timur's expedition. Babur records about Panjshir that, "It lies upon the road, and is in the immediate vicinity of Kafiristan. The inroads of the robbers of Kafiristan are made through Panjshir. In consequence of their vicinity of the Kafirs - the inhabitants of this district are happy to pay them a fixed contribution. Since I last invaded Hindustan, and subdued it (in 1527), the Kafirs have descended into Panjshir, and returned after slaying a great number of people and committing extensive damages." Per Tabakat-i-Akbari, the Mughal Emperor Akbar had dispatched his younger brother Mirza Muhammad Hakim, who was a staunch adherent of the missionary-minded Naqshbandi Sufi order, against the Kafirs of Katwar in 1582. Hakim was a semi-independent governor of Kabul. The Sifat-nama-yi Darviš Muhammad Hān-i Ğāzī of Kadi Muhammad Salim who accompanied the expedition mentions its details and gives Hakim the epithet of Darviš Khan Gazi. Muhammad Darvish's religious crusade fought its way from Lamghan to Alishang, and is stated to have conquered and converted 66 valleys to Islam. After conquering Tajau and Nijrau valleys in Panjshir area, his forces established a fort at Islamabad, located at the confluence of Alishang and Alingar rivers. They continued the raid up to Alishang and made their last effort against the non-Muslims of Alingar, fighting up to Mangu, the modern border between Pashai and Ashkun-speaking areas. The conquest does not seem to have had a lasting effect, as Henry George Raverty mentions that Kafirs still lived in upper part of Alishang and Tagau. Khulasat al-ansab of Hafiz Rahmat Khan stated that the Afghans and Kafirs of Lamghan were still fighting each other during the time of Jahangir. Final subjugation Under Amir Sher Ali Khan, Afghanistan was divided into provinces (wilayats) of Kabul, Kandahar, Herat and Afghan Turkestan. Uruzgan and Kafiristan were later incorporated into Kabul. Some parts of Kafiristan were already following Islam before its conquest. Amir Abdul Rahman Khan tried to persuade them to convert to Islam by deputing Kafir elders. The Kafirs were meanwhile poorly armed as compared to Afghans and numbered only 60,000. By 1895, the demarcation of nearby Chitral under indirect British rule, and the conquest of Pamirs by Russia, worried him about the endangerment of integration of Afghanistan through the independent Kafiristan. Afghan tribes meanwhile undertook slave raids in places like Kafiristan, Hazarajat, Badakhshan and Chitral. The territory between Afghanistan and British India was demarcated between 1894 and 1896. Part of the frontier lying between Nawa Kotal in outskirts of Mohmand country and Bashgal Valley on outskirts of Kafiristan were demarcated by 1895 with an agreement reached on 9 April 1895. Abdur Rahman wanted to force every community and tribal confederation with his single interpretation of Islam due to it being the only uniting factor. After the subjugation of the Hazaras, Kafiristan was the last remaining autonomous part. Field marshal Ghulam Hayder Khan sent a message to Kafirs of Barikut which stated, "It is not the duty of the government to compel, force or impose on them to accept, or take the path of the religion of Islam. The obligation that does exist is this: they render obedience and pay their taxes. As long as they do not disobey their command, they will not incinerate themselves with the fire of padishah's [king's] wrath. In addition, they are not to block the building of the road [that was planned through their territory]." Emir Abdur Rahman Khan's forces invaded Kafiristan in the winter of 1895–1896 and captured it in 40 days according to his autobiography. Columns invaded it from the west through Panjshir to Kullum, the strongest fort of the region. The columns from the north came through Badakhshan and from the east through Asmar. A small column also came from south-west through Laghman. The Kafirs were forcibly converted to Islam and resettled in Laghman, while the region was settled by veteran soldiers and other Afghans. Kafiristan was renamed as Nuristan. Other residents also converted to avoid the jizya. His victory was celebrated with the publishing of a poem in 1896 or 1897 and Faiz Mohammad Katib Hazara gave him the title of "Idol-Smasher". About 60,000 of the Kafirs became converts. Mullahs were deployed after the conquest to teach them about fundamentals of Islam. The large-scale conversion proved difficult however and complete Islamization took some time. Kafir elders are known to have offered sacrifices in their shrines upon hearing rumours of Rahman's death in 1901. Three main roads connecting Badakhshan with Kunar and Lamghan (Chigha Sirai-Munjan, Asmar-Badakhshan and Munjan-Laghman) were built after the conquest.

Durrani Empire

The Durrani Empire (; ), also called the Sadozai Kingdom(; ) and the Afghan Empire, (; ) was an Afghan empire founded and built by Ahmad Shah Abdali in parts of Central Asia, the Middle East and South Asia. At its maximum extent, the empire ruled over the modern-day countries of Afghanistan and Pakistan, as well as parts of northeastern and southeastern Iran, eastern Turkmenistan, and northwestern India. Next to the Ottoman Empire, the Durrani Empire was the greatest Muslim empire of the second half of the eighteenth century. Ahmad Shah Abdali was the son of Muhammad Zaman Khan Abdali (Chieftain of the Abdalis) and the commander of Nader Shah Afshar. Conquering the disunity in his tribe, in June 1747 after Nader's death, Ahmad Shah Abdali secured Afghanistan by taking Kandahar, Ghazni, Kabul and Peshawar that year, becoming the King of Afghanistan. After his accession, Ahmad Shah Abdali changed his tribal name to "Durrani", henceforth becoming known as Ahmad Shah Durrani. In 1749, the Mughal ruler had ceded sovereignty over much of northwest India to the Afghans. Ahmad Shah then set out westward to take possession of Mashhad, which was ruled by Shahrokh Shah and acknowledged Ahmad Shah's suzerainty. He next sent an army to subdue the areas north of the Hindu Kush down to the Amu Darya, and in short order, all the different tribes began joining his cause. Ahmad Shah and his forces then invaded India four times, taking control of Kashmir and the Punjab regions. Early in 1757, he sacked Delhi but permitted the Mughal emperor Alamgir II to remain in nominal control as long as the ruler acknowledged Ahmad Shah's suzerainty over the regions south of the Indus. After the death of Ahmad Shah Durrani in about 1772, his son Timur Shah Durrani became the next ruler of the Durrani dynasty. Under Timur Shah, Kabul became the new capital of the empire while Peshawar became the winter capital; however the empire began to crumble by this time. The dynasty would become heirs of Afghanistan for generations, up until Dost Mohammad Khan gained control in 1823. The Durrani Empire is considered the foundation of the modern state of Afghanistan, with Ahmad Shah Durrani being credited as "Father of the Nation". Reign of Ahmad Shah Durrani (1747–1772) Foundation of the Afghan state In 1709 Mirwais Hotak, chief of the Ghilji tribe of Kandahar Province, gained independence from the Safavid Persians. From 1722 to 1725, his son Mahmud Hotak briefly ruled large parts of Iran and declared himself as Shah of Persia. However, the Hotak dynasty came to a complete end in 1738 after being toppled and banished by the Afsharids who were led by Nader Shah Afshar of Persia. The year 1747 marks the definitive appearance of an Afghan political entity independent of both the Persian and Mughal empires. In July of that year a loya jirga (grand council) was called into session. The jirga lasted for nine days and two chief contestants emerged: Hajji Jamal Khan of the Mohammadzai lineage and Ahmad Khan of the Saddozai. Mohammad Sabir Khan, a noted darwish (holy man), who had earlier predicted that Ahmad Khan would be the leader of the Afghans, rose in the jirga and said Ahmad Khan reputedly hesitated to accept the open decision of the jirga, so Sabir Khan again intervened. He placed some wheat or barley sheaves in Ahmad Khan's turban, and crowned him Badshah, Durr-i-Dauran (Shah, Pearl of the Age). The jirga concluded near the city of Kandahar with Ahmad Shah Durrani being selected as the new leader of the Afghans, thus the Durrani dynasty was founded. Despite being younger than the other contenders, Ahmad Shah had several overriding factors in his favor. He belonged to a respectable family of political background, especially since his father had served as Governor of Herat who died in a battle defending the Afghans. Early victories One of Ahmad Shah's first military actions was to capture Qalati Ghilji and Ghazni from the Ghilji, and wrest Kabul and Peshawar from Mughal-appointed governor Nasir Khan. In 1749, the Mughal Emperor Ahmad Shah Bahadur was induced to cede Sindh, the Punjab region and the important trans Indus River to Ahmad Shah Durrani in order to save his capital from Afghan attack. Having thus gained substantial territories to the east without a fight, Ahmad Shah turned westward to take possession of Mashhad, which was ruled by Nader Shah Afshar's grandson, Shahrukh Afshar. Ahmad Shah next sent an army to subdue the areas north of the Hindu Kush mountains. In short order, the powerful army brought under its control the Tajik, Hazara, Uzbek, Turkmen, and other tribes of northern Afghanistan. Ahmad Shah invaded the remnants of the Mughal Empire a third time, and then a fourth, consolidating control over the Kashmir and Punjab regions, with Lahore being governed by Afghans. He sacked Delhi in 1757 but permitted the Mughal dynasty to remain in nominal control of the city as long as the ruler acknowledged Ahmad Shah's suzerainty over Punjab, Sindh, and Kashmir. Leaving his second son Timur Shah to safeguard his interests, Ahmad Shah left India to return to Afghanistan. Relations with China Alarmed by the expansion of China's Qing Dynasty up to the eastern border of Kazakhstan, Ahmad Shah attempted to rally neighboring Muslim khanates and the Kazakhs to unite and attack China, ostensibly to liberate its western Muslim subjects. Ahmad Shah halted trade with Qing China and dispatched troops to Kokand. However, with his campaigns in India exhausting the state treasury, and with his troops stretched thin throughout Central Asia, Ahmad Shah lacked sufficient resources to do anything except to send envoys to Beijing for unsuccessful talks. Third Battle of Panipat The Mughal power in northern India had been declining after the death of Emperor Aurangzeb, who died in 1707. In 1751–52, the Ahamdiya treaty was signed between the Marathas and Mughals, when Balaji Bajirao was the Peshwa. Through this treaty, the Marathas controlled virtually the whole of India from their capital at Pune and the Mughal rule was restricted only to Delhi (the Mughals remained the nominal heads of Delhi). Marathas were now straining to expand their area of control towards the Northwest of India. Ahmad Shah sacked the Mughal capital and withdrew with the booty he coveted. To counter the Afghans, Peshwa Balaji Bajirao sent Raghunathrao. He defeated the Rohillas and Afghan garrisons in Punjab and succeeded in ousting Timur Shah and his court from India and brought Lahore, Multan, Kashmir and other subahs on the Indian side of Attock under Maratha rule. Thus, upon his return to Kandahar in 1757, Ahmad was forced to return to India and face the formidable attacks of the Maratha Confederacy. Ahmad Shah declared a jihad (or Islamic holy war) against the Marathas, and warriors from various Afghan tribes joined his army, including the Baloch people under the command of Khan of Kalat Mir Nasir I of Kalat. Suba Khan Tanoli (Zabardast Khan) was selected as army chief of all military forces. Early skirmishes were followed by victory for the Afghans against the much larger Maratha garrisons in Northwest India and by 1759 Ahmad Shah and his army had reached Lahore and were poised to confront the Marathas. Ahmad Shah Durrani was famous for winning wars much larger than his army. By 1760, the Maratha groups had coalesced into a big enough army under the command of Sadashivrao Bhau. Once again, Panipat was the scene of a confrontation between two warring contenders for control of northern India. The Third Battle of Panipat (14 January 1761), fought between largely Muslim and largely Hindu armies was waged along a twelve-kilometer front. Despite decisively defeating the Marathas, what might have been Ahmad Shah's peaceful control of his domains was disrupted by many challenges. As far as losses are concerned, Afghans too suffered heavily in the Third Battle of Panipat. This weakened his grasp over Punjab which fell to the rising Sikh misls. There were rebellions in the north in the region of Bukhara. The Durranis decisively defeated the Marathas in the Third Battle of Panipat on 14 January 1761. The defeat at Panipat resulted in heavy losses for the Marathas, and was a huge setback for Peshwa Balaji Rao. He received the news of the defeat of Panipat on 24 January 1761 at Bhilsa, while leading a reinforcement force. Besides several important generals, he had lost his own son Vishwasrao in the Battle of Panipat. He died on 23 June 1761, and was succeeded by his younger son Madhav Rao I. Final years The victory at Panipat was the high point of Ahmad Shah's—and Afghan—power. However, even prior to his death, the empire began to unravel. In 1762, Ahmad Shah crossed the passes from Afghanistan for the sixth time to subdue the Sikhs. From this time and on, the domination and control of the Empire began to loosen, and by the time of Durrani's death he had lost parts of Punjab to the Sikhs, as well as earlier losses of northern territories to the Uzbeks, necessitating a compromise with them. He assaulted Lahore and, after taking their holy city of Amritsar, massacred thousands of Sikh inhabitants, destroyed their revered Golden Temple. Within two years, the Sikhs rebelled again and rebuilt their holy city of Amritsar. Ahmad Shah tried several more times to subjugate the Sikhs permanently, but failed. Durrani's forces instigated the Vaḍḍā Ghallūghārā when they killed thousands of Sikhs in the Punjab in 1762. Ahmad Shah also faced other rebellions in the north, and eventually he and the Uzbek Emir of Bukhara agreed that the Amu Darya would mark the division of their lands. Ahmad Shah retired to his home in the mountains east of Kandahar, where he died on 16 October 1772. He had succeeded to a remarkable degree in balancing tribal alliances and hostilities, and in directing tribal energies away from rebellion. He earned recognition as Ahmad Shah Baba, or "Father" of Afghanistan. The Durrani Empire lost its control over Kashmir to the Sikh Empire in the Battle of Shopian in 1819. Other Durrani rulers (1772–1823) Ahmad Shah's successors governed so ineptly during a period of profound unrest that within fifty years of his death, the Durrani empire per se was at an end, and Afghanistan was embroiled in civil war. Much of the territory conquered by Ahmad Shah fell to others in this half century. By 1818, the Sadozai rulers who succeeded Ahmad Shah controlled little more than Kabul and the surrounding territory within a 160-kilometer radius. They not only lost the outlying territories but also alienated other tribes and lineages among the Durrani Pashtuns. Humayun Mirza (1772) A few months before his death, Ahmad Shah summoned Timur Shah from Herat and publicly declared him heir to the Durrani Empire. Ahmad Shah made this decision without consulting with his tribal council, as a result the authority of the Durrani Emperor was put into question and created a growing rift that would toil the Durrani empire for years to come, as the tribal council had in majority, supported Ahmad Shah's eldest son and Timur Shah's brother, Sulaiman, the governor of Kandahar. Prominent figures in court who supported the Sulaiman faction were Shah Wali Khan, Ahmad Shah's Wazir, and Sardar Jahan Khan. The court had attempted to urge Ahmad Shah to reconsider his decision, coinciding with the fact that the eldest son should acend to the throne. Ahmad had ignored this, and quoted: "Timur Shah was infinitely more capable of governing you then his brother". As well as accusing Sulaiman of being "Violent without clemency", and out of favour with the Kandahari Durranis. Ahmad Shah's decision could have been influenced by his illness, which had affected his brain and his mental state, however choosing of succession to Timur Shah was likely to restrict power to the Senior Generals and the Durrani Tribal Council, to which he deemed as a threat to his dynasty in the future. When Ahmad Shah was on his death bed, Sadar Jahan Khan had capitalized on Timur Shah's far proximity with him ruling over Herat, and poisoned the ear of the Shah. This had worked as Timur Shah was denied an by Ahmad Shah on his deathbed, as a result, Timur Shah had begun mobilizing his forces for the inevitable conflict with his brother. Timur Shah's plans were stalled however, as a rebellion by Darwish Ali Khan under the Sunni Hazaras, likely instigated by the Sulaiman faction had risen up. Timur Shah had crushed this revolt quickly and Darwish Khan was imprisoned, however he had escaped. Timur Shah had then lured him into Herat, offering pardon, where then Timur Shah had ordered his execution where his nephew, Muhammad Khan would be appointed in his place. During the revolt of Darwish, Ahmad Shah had died of his illness on 16 October, 1772. Shah Wali Khan and Sardar Jahan Khan kept the Shah's death a secret by placing the body on a palanquin covered by thick curtains. They had then left the King's mountain, taking as much treasure as they could and marched to Kandahar. Shah Wali Khan had also announced to everyone that the king was ill and had given orders to not disturb him except his trusted officials. To make the deception more believable, Ahmad Shah's chief eunuch, Yaqut Khan had brought food for the "Sick" Ruler. Shah wali Khan had then notified Sulaiman that Ahmad Shah was dead and proclaimed Sulaiman as king. However, many of the Amirs including Mahadad Khan had disliked Shah Wali's ambitions, and thus had fled to Timur's side, also notifying him of the ongoing situation at Kandahar. Timur Shah had then marched toward Kandahar to face Shah Humayun. Shah Wali, fearing of Timur's march had consulted with Shah Humayun, and had agreed on him marching out to Prince Timur Shah to welcome him. He left Kandahar with over 150 horsemen and had arrived at Prince Timur's force at Farah. Having not sent word, once Shah Wali had dismounted, Timur Shah ordered the killing of Shah Wali. Angu Khan Bamiza'i assassinated Shah Wali Khan and his two sons, including 2 of his sisters children. Shah Sulayman surrendered the throne to Timur Shah following this, and became a loyal follower of him according to the depiction of Amir Habibullah Khan. Timur Shah ascended the throne in November 1772. Timur Shah (1772–1793) After his father, Ahmad Shah Durrani's death, he fought his brother Humayun Mirza for the throne, with Humayun supported by Shah Wali Khan. Shah Wali was killed by Timur Shah as he attempted to ride into his camp and beg for peace and mercy. Timur Shah then marched to Kandahar, forcing Humayun to either flee or stay as a devout supporter for Timur Shah. With his throne secured, he begun consolidating his power, with efforts to drive power away from the Durrani Pashtuns, and more toard the growing influential Qizilbash and Mongol guards consisted in his army. Timur Shah would also move the capital of the Durrani Realm from Kandahar to Kabul, as a better base of operation to combat any threat arriving from abywhere, as Kabul was essentially the heart of the empire. After consolidating his power, Timur Shah marched against the Sikh's in 1780 in a Jihad, and decisively defeated the Sikhs, forcing them to return Multan toward Durrani Suzarainty after it was seized after the death of Ahmad Shah Durrani. Timur Shah, having secured Punjab, also faced recurring rebellions against him, including an assassination attempt earl yin his reign at Peshawar. Timur Shah would encounter harsh resistance and rebellion, prominently those of Fayz Allah Khan, Azad Khan, and Arsalan Khan. Timur Shah in his reign also fought against Shah Murad, the ruler of Bukhara who attempted raids into Afghan Turkestan and Khorasan, often harassing the Durrani vassal of the Afsharid dynasty centred in Mashhad. In conclusion, Timur Shah spent most of his reign consolidating the empire, while also fighting off rebellion, he prove himself as a competent leader from holding the unstable empire apart. Timur Shah died on 20 May, 1793, succeeded by his son, Zaman Shah Durrani Zaman Shah (1793–1801) After the death of Timur Shah, three of his sons, the governors of Kandahar, Herat and Kabul, contended for the succession. Zaman Shah, governor of Kabul, held the field by virtue of being in control of the capital, and became shah at the age of twenty-three. Many of his half-brothers were imprisoned on their arrival in the capital for the purpose, ironically, of electing a new shah. The quarrels among Timur's descendants that threw Afghanistan into turmoil also provided the pretext for the interventions of outside forces. The efforts of the Sadozai heirs of Timur to impose a true monarchy on the truculent Pashtun tribes, and their efforts to rule absolutely and without the advice of the other major Pashtun tribal leaders, were ultimately unsuccessful. The Sikhs started to rise under the command of Sikh chief, Ranjit Singh, who succeeded in wresting power from Zaman's forces. Later, when Zaman was blinded by his brother, Ranjit Singh gave him asylum in Punjab. Zaman's downfall was triggered by his attempts to consolidate power. Although it had been through the support of the Barakzai chief, Painda Khan Barakzai, that he had come to the throne, Zaman soon began to remove prominent Barakzai leaders from positions of power and replace them with men of his own lineage, the Sadozai. This upset the delicate balance of Durrani tribal politics that Ahmad Shah had established and may have prompted Painda Khan and other Durrani chiefs to plot against the shah. Painda Khan and the chiefs of the Nurzai and the Alizai Durrani clans were executed, as was the chief of the Qizilbash clan. Painda Khan's son fled to Iran and pledged the substantial support of his Barakzai followers to a rival claimant to the throne, Zaman's younger brother, Mahmud Shah. The clans of the chiefs Zaman had executed joined forces with the rebels, and they took Kandahar without bloodshed. Mahmud Shah had then proceeded to march to Kabul, where he met Zaman Shah and his army on the way from Ghanzi to Kabul, Zaman Shah was decisively defeated, including portions of his army fleeing to Mahmud Shah's cause. Mahmud Shah ordered the lancing of Zaman Shah's eyes, and had succeeded Zaman Shah on the throne of the Durrani Empire. Mahmud Shah (first reign, 1801–1803) Zeman Shah's overthrow in 1801 was not the end of civil strife in Afghanistan, but the beginning of even greater violence. Mahmud Shah's first reign lasted for only two years before he was replaced by Shuja Shah. Shuja Shah (1803–1809 and 1839–1842) Yet another of Timur Shah's sons, Shuja Shah (or Shah Shuja), ruled for only six years. On June 7, 1809, Shuja Shah signed a treaty with the British, which included a clause stating that he would oppose the passage of foreign troops through his territories. This agreement, the first Afghan pact with a European power, stipulated joint action in case of Franco-Persian aggression against Afghan or British dominions. Only a few weeks after signing the agreement, Shuja was deposed by his predecessor, Mahmud. Much later, he was reinstated by the British, ruling during 1839–1842. Two of his sons also ruled for a brief period in 1842. Mahmud Shah (second reign, 1809–1818) Mahmud's second reign lasted 9 years, where he had further attempted to consolidate power, but was deposed by his brother in 1818, Mahmud's reign was also disputed in 1810, while he was campaigning, another one of Timur Shah Durrani's sons had seized the throne, but was defeated by Shah Mahmud in 1810. Abbas Mirza (1810) Sultan Ali Shah (1818–1819) Ali Shah was another son of Timur Shah. He seized power for a brief period in 1818–1819. in 1818 or 1819, He was strangled by his brother, Isma'il. Ayub Shah (1819–1823) Ayub Shah was another son of Timur Shah, who took control of the Durrani Empire after the death of Ali Shah Durrani. The Durrani Empire lost its control over Kashmir to the Sikh Empire in the Battle of Shopian in 1819. Ayub Shah was himself later deposed, and presumably killed in 1823. Military The Durrani military was based on cavalry armed with flintlocks who performed hit-and-run attacks, combining new technology in firearms with Turco-Mongol tactics. The core of the Durrani army were the 10,000 sher-bacha (blunderbuss)-carrying mounted ghulams (slave-soldiers) of which a third were previously Shia soldiers (Qizilbash) of Nader Shah. Many others were also former troops of Nader Shah. The bulk of the army were Afghan irregular tribal cavalry armed with lance and broadsword. Mounted archers were still used but were uncommon due to the difficulty of training them. Infantry played a very small role in the Durrani army and, with the exception of light swivel guns mounted on camels, the Zamburak, so did artillery.

Aimaq people

The Aimaq () or Chahar Aimaq (), also transliterated as Aimagh, Aimak and Aymaq, are a collection of Sunni and mostly Persian-speaking nomadic and semi-nomadic tribes. They live mostly in the central and western highlands of Afghanistan, especially in Ghor, Badghis. Aimaqs were originally known as chahar ("four") Aymaqs: the Taymani (the main element in the population of Ghor), the Firozkohi (mostly in Badghis), the Jamshidi and the Timuri. Other sources state that the Aimaq Hazara are one of the Chahar, with the Timuri instead being of the "lesser Aimaqs" or Aimaq-e digar ("other Aimaqs"). The Aimaq speak several subdialects of the Aimaq dialect of Persian language, but some southern groups of Taymani, Firozkohi, and northeastern Timuri Aimaqs have adopted the Pashto language. Origin and culture The Aimaqs claim different origins based on their tribal background. Some claim to be descended from the troops of Genghis Khan. Other tribes such as the Taymani (Aimaq tribe) and Firozkohi claim descent from other Pashtun tribes. Aimaq is a Mongolic word that means "tribe" or "grazing territory". Of all Aimaqs, Aimaq Hazara and Timuri are closest to the Turco-Mongol tradition since they are semi-nomadic tribes and some of them live in yurts, whereas other Aimaqs live in traditional Afghan black tents. The Aimaq are largely nomadic to semi-nomadic goat and sheep herders. They also trade with villages and farmers during migrations for pastures for their livestock. The material culture and foodstuffs of the Aimaq include skins, carpets, milk, dairy products and more. They trade these products to settled peoples in return for vegetables, grains, fruits, nuts, and other types of foods and goods. Classification of tribes Aimaq tribes Demographics Estimates of the Aimaq population vary between 250,000 and 500,000. They are largely Sunni Muslims—except for the Jamshidi who are mainly Ismaili Shia in the main—and in contrast to the Hazara, who are mostly Shia Muslims.

Arcturus

|- bgcolor="#FFFAFA" | Note (category: variability): || H and K emission vary. Arcturus is the brightest star in the northern constellation of Boötes, the fourth-brightest in the night sky, and the brightest in the northern celestial hemisphere. It is designated α Boötis, which is Latinized to Alpha Boötis. Together with Spica and Denebola (or Regulus, depending on the source), Arcturus is part of the Spring Triangle asterism and, by extension, also of the Great Diamond along with the star Cor Caroli. When viewed from Earth, it appears to be positioned almost at the north galactic pole of the Milky Way. Located relatively close at 36.7 light-years from the Sun, Arcturus is a single red giant of spectral type K1.5III—an aging star around 7.1 billion years old that has used up its core hydrogen and evolved off the main sequence. It is about the same mass as the Sun, but has expanded to 25 times its size and is around 170 times as luminous. Its diameter is 35 million kilometres. Nomenclature The designation of Arcturus as α Boötis (Latinised to Alpha Boötis) was made by Johann Bayer in 1603. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included Arcturus for α Boötis. Observation With an apparent visual magnitude of −0.05, Arcturus is the brightest star in the northern celestial hemisphere and the fourth-brightest star in the night sky, after Sirius (−1.46 apparent magnitude), Canopus (−0.72) and α Centauri (combined magnitude of −0.27). However, α Centauri AB is a binary star, whose components are both fainter than Arcturus. This makes Arcturus the third-brightest individual star, just ahead of α Centauri A (officially named Rigil Kentaurus), whose apparent magnitude . The French mathematician and astronomer Jean-Baptiste Morin observed Arcturus in the daytime with a telescope in 1635, a first for any star other than the Sun and supernovae. Arcturus has been seen at or just before sunset with the naked eye. Arcturus is visible from both of Earth's hemispheres as it is located 19° north of the celestial equator. The star culminates at midnight on 27 April, and at 9 p.m. on June 10 being visible during the late northern spring or the southern autumn. From the northern hemisphere, an easy way to find Arcturus is to follow the arc of the handle of the Big Dipper (or Plough). By continuing in this path, one can find Spica, "Arc to Arcturus, then spike (or speed on) to Spica". Ptolemy described Arcturus as subrufa ("slightly red"): it has a B-V color index of +1.23, roughly midway between Pollux (B-V +1.00) and Aldebaran (B-V +1.54). η Boötis, or Muphrid, is only 3.3 light-years distant from Arcturus, and would have a visual magnitude −2.5, about as bright as Mercury from Earth, whereas an observer on the former system would find Arcturus as bright as Venus as seen from Earth. In 1984, the 90 cm (36-inch) reflecting Yapp telescope at Herstmonceux was tested with an echelle spectrograph from Queen's University Belfast and a CCD camera. Observations of the stars Arcturus and Deneb (Alpha Cygni) were conducted in the summer of 1984. Physical characteristics Based upon an annual parallax shift of 88.83 milliarcseconds as measured by the Hipparcos satellite, Arcturus is from the Sun. The parallax margin of error is 0.54 milliarcseconds, translating to a distance margin of error of ±. Because of its proximity, Arcturus has a high proper motion, two arcseconds a year, greater than any first magnitude star other than α Centauri. Arcturus is moving rapidly () relative to the Sun, and is now almost at its closest point to the Sun. Closest approach will happen in about 4,000 years, when the star will be a few hundredths of a light-year closer to Earth than it is today. (In antiquity, Arcturus was closer to the centre of the constellation.) Arcturus is thought to be an old-disk star, and appears to be moving with a group of 52 other such stars, known as the Arcturus stream. With an absolute magnitude of −0.30, Arcturus is, together with Vega and Sirius, one of the most luminous stars in the Sun's neighborhood. It is about 110 times brighter than the Sun in visible light wavelengths, but this underestimates its strength as much of the light it gives off is in the infrared; total (bolometric) power output is about 180 times that of the Sun. With a near-infrared J band magnitude of −2.2, only Betelgeuse (−2.9) and R Doradus (−2.6) are brighter. The lower output in visible light is due to a lower efficacy as the star has a lower surface temperature than the Sun. As a single star, the mass of Arcturus cannot be measured directly, but models suggest it is slightly greater than that of the Sun. Evolutionary matching to the observed physical parameters gives a mass of , while the oxygen isotope ratio for a first dredge-up star gives a mass of . The star displays magnetic activity that is heating the coronal structures, and it undergoes a solar-type magnetic cycle with a duration that is probably less than 14 years. A weak magnetic field has been detected in the photosphere with a strength of around half a gauss. The magnetic activity appears to lie along four latitudes and is rotationally modulated. Arcturus is estimated to be around 6 to 8.5 billion years old, but there is some uncertainty about its evolutionary status. Based upon the color characteristics of Arcturus, it is currently ascending the red-giant branch and will continue to do so until it accumulates a large enough degenerate helium core to ignite the helium flash. It has likely exhausted the hydrogen from its core and is now in its active hydrogen shell burning phase. However, Charbonnel et al. (1998) placed it slightly above the horizontal branch, and suggested it has already completed the helium flash stage. Spectrum Arcturus is an evolved red giant star with an early K-type stellar classification. It is frequently assigned the spectral type of K0III, but in 1989 was used as the spectral standard for type K1.5III Fe−0.5, with the suffix notation indicating a mild underabundance of iron compared to typical stars of its type. As the brightest K-type giant in the sky, it has been the subject of multiple atlases with coverage from the ultraviolet to infrared. The spectrum shows a dramatic transition from emission lines in the ultraviolet to atomic absorption lines in the visible range and molecular absorption lines in the infrared. This is due to the optical depth of the atmosphere varying with wavelength. The spectrum shows very strong absorption in some molecular lines that are not produced in the photosphere but in a surrounding shell. Examination of carbon monoxide lines show the molecular component of the atmosphere extending outward to 2–3 times the radius of the star, with the chromospheric wind steeply accelerating to 35–40 km/s in this region. Astronomers term "metals" those elements with higher atomic numbers than helium. The atmosphere of Arcturus has an enrichment of alpha elements relative to iron but only about a third of solar metallicity. Arcturus is possibly a Population II star. Oscillations As one of the brightest stars in the sky, Arcturus has been the subject of a number of studies in the emerging field of asteroseismology. Belmonte and colleagues carried out a radial velocity (Doppler shift of spectral lines) study of the star in April and May 1988, which showed variability with a frequency of the order of a few microhertz (μHz), the highest peak corresponding to 4.3 μHz (2.7 days) with an amplitude of 60 ms−1, with a frequency separation of c. 5 μHz. They suggested that the most plausible explanation for the variability of Arcturus is stellar oscillations. Asteroseismological measurements allow direct calculation of the mass and radius, giving values of and . This form of modelling is still relatively inaccurate, but a useful check on other models. Possible planetary system Hipparcos satellite astrometry suggested that Arcturus is a binary star, with the companion about twenty times dimmer than the primary and orbiting close enough to be at the very limits of humans' current ability to make it out. Recent results remain inconclusive, but do support the marginal Hipparcos detection of a binary companion. In 1993, radial velocity measurements of Aldebaran, Arcturus and Pollux showed that Arcturus exhibited a long-period radial velocity oscillation, which could be interpreted as a substellar companion. This substellar object would be nearly 12 times the mass of Jupiter and be located roughly at the same orbital distance from Arcturus as the Earth is from the Sun, at 1.1 astronomical units. However, all three stars surveyed showed similar oscillations yielding similar companion masses, and the authors concluded that the variation was likely to be intrinsic to the star rather than due to the gravitational effect of a companion. So far no substellar companion has been confirmed. Mythology One astronomical tradition associates Arcturus with the mythology around Arcas, who was about to shoot and kill his own mother Callisto who had been transformed into a bear. Zeus averted their imminent tragic fate by transforming the boy into the constellation Boötes, called Arctophylax "bear guardian" by the Greeks, and his mother into Ursa Major (Greek: Arctos "the bear"). The account is given in Hyginus's Astronomy. Aratus in his Phaenomena said that the star Arcturus lay below the belt of Arctophylax, and according to Ptolemy in the Almagest it lay between his thighs. An alternative lore associates the name with the legend around Icarius, who gave the gift of wine to other men, but was murdered by them, because they had had no experience with intoxication and mistook the wine for poison. It is stated this Icarius, became Arcturus, while his dog, Maira, became Canicula (Procyon), although "Arcturus" here may be used in the sense of the constellation rather than the star. Etymology and cultural significance The traditional name Arcturus is derived from the Ancient Greek Ἀρκτοῦρος (Arktouros) and means "Guardian of the Bear", ultimately from ἄρκτος (arktos), "bear" and οὖρος (ouros), "watcher, guardian". The name has been used since at least the time of Hesiod, circa 700 BC. It fell out of use in favour of Arabic names until it was revived in the Renaissance. In Arabic, Arcturus is one of two stars called al-simāk "the uplifted ones" (the other is Spica). Arcturus is specified as السماك الرامح as-simāk ar-rāmiħ "the uplifted one of the lancer". The term Al Simak Al Ramih has appeared in Al Achsasi Al Mouakket catalogue (translated into Latin as Al Simak Lanceator). This has been variously romanized in the past, leading to obsolete variants such as Aramec and Azimech. For example, the name Alramih is used in Geoffrey Chaucer's A Treatise on the Astrolabe (1391). Another Arabic name is Haris-el-sema, from حارس السماء ħāris al-samā’ "the keeper of heaven". or حارس الشمال ħāris al-shamāl’ "the keeper of north". In Indian astronomy, Arcturus is called Swati or Svati (Devanagari स्वाति, Transliteration IAST svāti, svātī́), possibly 'su' + 'ati' ("great goer", in reference to its remoteness) meaning very beneficent. It has been referred to as "the real pearl" in Bhartṛhari's kāvyas. In Chinese astronomy, Arcturus is called Da Jiao (), because it is the brightest star in the Chinese constellation called Jiao Xiu (). Later it became a part of another constellation Kang Xiu (). The Wotjobaluk Koori people of southeastern Australia knew Arcturus as Marpean-kurrk, mother of Djuit (Antares) and another star in Boötes, Weet-kurrk (Muphrid). Its appearance in the north signified the arrival of the larvae of the wood ant (a food item) in spring. The beginning of summer was marked by the star's setting with the Sun in the west and the disappearance of the larvae. The people of Milingimbi Island in Arnhem Land saw Arcturus and Muphrid as man and woman, and took the appearance of Arcturus at sunrise as a sign to go and harvest rakia or spikerush. The Weilwan of northern New South Wales knew Arcturus as Guembila "red". In Inuit astronomy, Arcturus is called the Old Man (Uttuqalualuk in Inuit languages) and The First Ones (Sivulliik in Inuit languages). The Miꞌkmaq of eastern Canada saw Arcturus as Kookoogwéss, the owl. Arcturus had several names that described its significance to indigenous Polynesians. In the Society Islands, Arcturus, called Ana-tahua-taata-metua-te-tupu-mavae ("a pillar to stand by"), was one of the ten "pillars of the sky", bright stars that represented the ten heavens of the Tahitian afterlife. In Hawaii, the pattern of Boötes was called Hoku-iwa, meaning "stars of the frigatebird". This constellation marked the path for Hawaiʻiloa on his return to Hawaii from the South Pacific Ocean. The Hawaiians called Arcturus Hoku-leʻa. It was equated to the Tuamotuan constellation Te Kiva, meaning "frigatebird", which could either represent the figure of Boötes or just Arcturus. However, Arcturus may instead be the Tuamotuan star called Turu. The Hawaiian name for Arcturus as a single star was likely Hoku-leʻa, which means "star of gladness", or "clear star". In the Marquesas Islands, Arcturus was probably called Tau-tou and was the star that ruled the month approximating January. The Māori and Moriori called it Tautoru, a variant of the Marquesan name and a name shared with Orion's Belt. Early-20th-century Armenian scientist Nazaret Daghavarian theorized that the star commonly referred to in Armenian folklore as Gutani astgh (Armenian: Գութանի աստղ; lit. star of the plow) was in fact Arcturus, as the constellation of Boötes was called "Ezogh" (Armenian: Եզող; lit. the person who is plowing) by Armenians. In culture As one of the brightest stars in the sky, Arcturus has been significant to observers since antiquity. Historical cultures Prehistoric Polynesian navigators knew Arcturus as Hōkūleʻa, the "Star of Joy". Arcturus is the zenith star of the Hawaiian Islands. Using Hōkūleʻa and other stars, the Polynesians launched their double-hulled canoes from Tahiti and the Marquesas Islands. Traveling east and north they eventually crossed the equator and reached the latitude at which Arcturus would appear directly overhead in the summer night sky. Knowing they had arrived at the exact latitude of the island chain, they sailed due west on the trade winds to landfall. If Hōkūleʻa could be kept directly overhead, they landed on the southeastern shores of the Big Island of Hawaii. For a return trip to Tahiti the navigators could use Sirius, the zenith star of that island. Since 1976, the Polynesian Voyaging Society's Hōkūleʻa has crossed the Pacific Ocean many times under navigators who have incorporated this wayfinding technique in their non-instrument navigation. In ancient Mesopotamia, it was linked to the god Enlil, and also known as Shudun, "yoke", or SHU-PA of unknown derivation in the Three Stars Each Babylonian star catalogues and later MUL.APIN around 1100 BC. In Ancient Rome, the star's celestial activity was supposed to portend tempestuous weather, and a personification of the star acts as narrator of the prologue to Plautus' comedy Rudens (circa 211 BC). In the Middle Ages, Arcturus was considered a Behenian fixed star and attributed to the stone Jasper and the plantain herb. Cornelius Agrippa listed its kabbalistic sign under the alternate name Alchameth. The Karandavyuha sutra, compiled at the end of the 4th century or beginning of the 5th century, names one of Avalokiteśvara's meditative absorptions as "The face of Arcturus". One of the possible etymologies offered for the name "Arthur" assumes that it is derived from "Arcturus" and that the early-medieval character on whom the myth of King Arthur is based was originally named for the star. Modern cultures Arcturus achieved fame when its light was rumored to be the mechanism used to open the 1933 Chicago World's Fair. The star was chosen as it was thought that light from Arcturus had started its journey at about the time of the previous Chicago World's Fair in 1893 (at 36.7 light-years away, the light actually started in 1896). The star is mentioned in the 1977 documentary film Powers of Ten, in which it is seen when a camera zooms from Earth to the whole of the known universe. A notable science fiction novel, A Voyage to Arcturus was published in 1920 and was written by David Lindsay.

Androphagi

Androphagi (, cannibals, literally "man-eaters"), according to Herodotus, lived some distance north of Scythia in an area later hypothesised to be the forests between the upper waters of the Dnepr and Don. Also according to Herodotus, when King Darius the Great led a Persian invasion into Scythian territory in what is now Southern Russia, the Androphagi fled when the warring armies passed through their territory. Etymology Historian Marija Gimbutas has hypothesized that "Androphagoi" is a Greek translation of *mard-xwaar "man-eater" in the old North Iranian language of the Scythians. From *mard-xwaar one can derive "Mordva" or "Mordvin", the Russian name of the Finnic Erzya and Moksha peoples of east-central European Russia. From Herodotus we can deduce a location for the Androphagoi that is approximately the same as that occupied by the modern Mordvins. Max Vasmer rejected this etymology as unsubstantiated. Ancient accounts Herodotus first wrote of andropophagi in his Histories, where he described them as one of several tribes near Scythia. An extra note indicates that the andropophagi are cannibals, as reflected in their name: Pliny the Elder later wrote in his Naturalis Historia that the same cannibals near Scythia wore the scalps of men on their chest.

Albert Brooks

Albert Brooks (born Albert Lawrence Einstein; July 22, 1947) is an American actor, comedian, and filmmaker. He received an Academy Award nomination for Best Supporting Actor for 1987's Broadcast News and was widely praised for his performance as a ruthless Jewish mobster in the 2011 neo-noir film Drive. Brooks has also played in Taxi Driver (1976), Private Benjamin (1980), Unfaithfully Yours (1984), and My First Mister (2001). He has written, directed, and starred in several comedy films, such as Modern Romance (1981), Lost in America (1985), and Defending Your Life (1991). He is also the author of 2030: The Real Story of What Happens to America (2011). His voice acting credits include Marlin in Finding Nemo (2003) and Finding Dory (2016), Tiberius in The Secret Life of Pets (2016), and recurring guest voices for The Simpsons, including Russ Cargill in The Simpsons Movie (2007) and Hank Scorpio in "You Only Move Twice". Early life Brooks was born Albert Lawrence Einstein on July 22, 1947 into a Jewish show business family in Beverly Hills, California, to Thelma Leeds (née Goodman), an actress, and Harry Einstein, a radio comedian who performed on Eddie Cantor's radio program and was known as "Parkyakarkus". He is the youngest of three sons. His older brothers are the late comedic actor Bob Einstein (1942-2019), better known as a character he created named "Super Dave Osborne", his Officer Judy character on the Smothers Brothers Comedy Hour, and for a recurring role in Curb Your Enthusiasm; and Cliff Einstein (b. 1939), a partner and longtime chief creative officer at Los Angeles advertising agency Dailey & Associates. His older half-brother was Charles Einstein (1926-2007), a writer for such television programs as Playhouse 90 and Lou Grant. His grandparents emigrated from Austria and Russia. He grew up among show business families in southern California, attending Beverly Hills High School with Richard Dreyfuss and Rob Reiner. Career Early career Brooks attended Carnegie Mellon University in Pittsburgh, but dropped out after one year to focus on his comedy career. By the age of 19, he had changed his professional name to Albert Brooks, joking that "the real Albert Einstein changed his name to sound more intelligent". He quickly became a regular on variety and talk shows during the late 1960s and early 1970s. Brooks led a new generation of self-reflective baby-boomer comics appearing on NBC's The Tonight Show Starring Johnny Carson. His onstage persona, that of an egotistical, narcissistic, nervous comic, an ironic showbiz insider who punctured himself before an audience by disassembling his mastery of comedic stagecraft, influenced other '70s post-modern comedians, including Steve Martin, Martin Mull, and Andy Kaufman. After two successful comedy albums, Comedy Minus One (1973) and the Grammy Award–nominated A Star Is Bought (1975), Brooks left the stand-up circuit to try his hand as a filmmaker. He had already made his first short film, The Famous Comedians School, a satiric short and an early example of the mockumentary subgenre that was aired in 1972 on the PBS show The Great American Dream Machine. In 1975, Brooks directed six short films for the first season of NBC's Saturday Night Live In 1976, he appeared in his first mainstream film role, in Martin Scorsese's landmark Taxi Driver; Scorsese allowed Brooks to improvise much of his dialogue. Brooks had landed the role after moving to Los Angeles to enter the film business. Brooks directed his first feature film, Real Life, in 1979. The film, in which Brooks (playing a version of himself) films a typical suburban family in an effort to win both an Oscar and a Nobel Prize, was a sendup of PBS's An American Family documentary. It has also been viewed as foretelling the future emergence of reality television. Brooks also made a cameo appearance in the film Private Benjamin (1980), starring Goldie Hawn. 1981–1999 Through the 1980s and 1990s, Brooks co-wrote (with longtime collaborator Monica Johnson), directed and starred in a series of well-received comedies, playing variants on his standard neurotic and self-obsessed character. These include 1981's Modern Romance, where Brooks played a film editor desperate to win back his ex-girlfriend (Kathryn Harrold). The film received a limited release and ultimately grossed under $3 million domestically. It was well received by critics, with one reviewer commenting that the film was "not Brooks at his best, but still amusing". His best-received film, Lost in America (1985), featured Brooks and Julie Hagerty as a couple who leave their yuppie lifestyle and drop out of society to live in a motor home as they have always dreamed of doing, meeting disappointment. Brooks's Defending Your Life (1991) placed his lead character in the afterlife, put on trial to justify his human fears and determine his cosmic fate. Critics responded to the offbeat premise and the chemistry between Brooks and Meryl Streep, as his post-death love interest. His later efforts did not find large audiences, but still retained Brooks's touch as a filmmaker. He garnered positive reviews for Mother (1996), which starred Brooks as a middle-aged writer moving back home to resolve tensions between himself and his mother (Debbie Reynolds). 1999's The Muse featured Brooks as a Hollywood screenwriter who has "lost his edge", using the services of an authentic muse (Sharon Stone) for inspiration. In an interview with Brooks with regards to The Muse, Gavin Smith wrote, "Brooks's distinctive film making style is remarkably discreet and unemphatic; he has a light, deft touch, with a classical precision and economy, shooting and cutting his scenes in smooth, seamless successions of medium shots, with clean, high-key lighting." Brooks has appeared as a guest voice on The Simpsons seven times during its run (always under the name A. Brooks). He is described as the best guest star in the show's history by IGN, particularly for his role as supervillain Hank Scorpio in the episode "You Only Move Twice". Brooks also acted in other writers' and directors' films during the 1980s and 1990s. He had a cameo in the opening scene of Twilight Zone: The Movie, playing a driver whose passenger (Dan Aykroyd) has a shocking secret. In James L. Brooks's hit Broadcast News (1987), Albert Brooks was nominated for an Academy Award for Best Supporting Actor for playing an insecure, supremely ethical network TV reporter, who offers the rhetorical question, "Wouldn't this be a great world if insecurity and desperation made us more attractive?" He also won positive notices for his role in 1998's Out of Sight, playing an untrustworthy banker and ex-convict. 2000–present Brooks received positive reviews for his portrayal of a dying retail store owner who befriends disillusioned teen Leelee Sobieski in My First Mister (2001). Brooks continued his voiceover work in Pixar's Finding Nemo (2003), as the voice of Marlin, one of the film's protagonists. In 2005, his film Looking for Comedy in the Muslim World was dropped by Sony Pictures due to their desire to change the title. Warner Independent Pictures purchased the film and gave it a limited release in January 2006; the film received mixed reviews and a low box office gross. As with Real Life, Brooks plays a fictionalized "Albert Brooks", a filmmaker ostensibly commissioned by the U.S. government to see what makes the Muslim people laugh, and sending him on a tour of India and Pakistan. In 2006 he appeared in the documentary film Wanderlust as David Howard from Lost in America. The documentary included many other well-known people. In 2007, he continued his long-term collaboration with The Simpsons by voicing Russ Cargill, the central antagonist of The Simpsons Movie. He has played Lenny Botwin, Nancy Botwin's estranged father-in-law, on Showtime's television series Weeds. St. Martin's Press published his first novel, 2030: The Real Story of What Happens to America, on May 10, 2011. In 2011, Brooks co-starred as the vicious gangster Bernie Rose, the main antagonist in the film Drive, alongside Ryan Gosling and Carey Mulligan. His performance received much critical praise and positive reviews, with several critics proclaiming Brooks's performance as one of the film's best aspects. After receiving awards and nominations from several film festivals and critic groups, but not an Academy Award nomination, Brooks responded humorously on Twitter, "And to the Academy: ‘You don't like me. You really don't like me’." In 2016, Brooks voiced Tiberius, a curmudgeonly red-tailed hawk, in The Secret Life of Pets, and reprised the role of Marlin from Finding Nemo in the 2016 sequel Finding Dory. Personal life In 1997, Brooks married artist Kimberly Shlain, daughter of surgeon and writer Leonard Shlain. They have two children, Jacob and Claire.

https://en.wikipedia.org/wiki/Antares

Antares

Antares (pronounced ), designated α Scorpii (Latinised to Alpha Scorpii), is on average the fifteenth-brightest star in the night sky, and the brightest object in the constellation of Scorpius. Distinctly reddish when viewed with the naked eye, Antares is a slow irregular variable star that ranges in brightness from apparent magnitude +0.6 to +1.6. Often referred to as "the heart of the scorpion", Antares is flanked by σ Scorpii and τ Scorpii near the center of the constellation. Classified as spectral type M1.5Iab-Ib, Antares is a red supergiant, a large evolved massive star and one of the largest stars visible to the naked eye. Its exact size remains uncertain, but if placed at the center of the Solar System, it would reach to somewhere between the orbits of Mars and Jupiter. Its mass is calculated to be around 12 times that of the Sun. Antares is the brightest, most massive, and most evolved stellar member of the nearest OB association, the Scorpius–Centaurus Association, located at the rim of the Upper Scorpius part illuminating the Rho Ophiuchi cloud complex in its foreground. Antares is a member of the Upper Scorpius subgroup of the association, which contains thousands of stars with a mean age of 11 million years, about from Earth. Antares appears as a single star when viewed with the naked eye, but it is actually a binary star, with its two components called α Scorpii A and α Scorpii B. The brighter of the pair is the red supergiant, while the fainter is a hot main sequence star of magnitude 5.5. Nomenclature α Scorpii (Latinised to Alpha Scorpii) is the star's Bayer designation. Antares has the Flamsteed designation 21 Scorpii, as well as catalogue designations such as HR 6134 in the Bright Star Catalogue and HD 148478 in the Henry Draper Catalogue. As a prominent infrared source, it appears in the Two Micron All-Sky Survey catalogue as 2MASS J16292443-2625549 and the Infrared Astronomical Satellite (IRAS) Sky Survey Atlas catalogue as IRAS 16262–2619. It is also catalogued as a double star WDS J16294-2626 and CCDM J16294-2626. Antares is a variable star and is listed in the General Catalogue of Variable Stars but as a Bayer-designated star it does not have a separate variable star designation. Its traditional name Antares derives from the Ancient Greek , meaning "rival to-Ares" ("opponent to-Mars"), due to the similarity of its reddish hue to the appearance of the planet Mars. The comparison of Antares with Mars may have originated with early Mesopotamian astronomers which is considered an outdated speculation because the name of this star in Mesopotamian astronomy has always been "heart of Scorpon" and it was associated with Goddess Lisi(n). Some scholars have speculated that the star may have been named after Antar, or Antarah ibn Shaddad, the Arab warrior-hero celebrated in the pre-Islamic poems Mu'allaqat. However, the name "Antares" is already proven in the Greek culture, e.g. in Ptolemy's Almagest and Tetrabiblos. In 2016, the International Astronomical Union organised a Working Group on Star Names (WGSN) to catalog and standardise proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN, which included Antares for the star α Scorpii A. It is now so entered in the IAU Catalog of Star Names. Observation Antares is visible all night around May 31 of each year, when the star is at opposition to the Sun. Antares then rises at dusk and sets at dawn as seen at the equator. For two to three weeks on either side of November 30, Antares is not visible in the night sky from mid-northern latitudes, because it is near conjunction with the Sun. In higher northern latitudes, Antares is only visible low in the south in summertime. Higher than 64° northern latitude, the star does not rise at all. Antares is easier to see from the southern hemisphere due to its southerly declination. In the whole of Antarctica, the star is circumpolar as the whole continent is above 64° S latitude. History Radial velocity variations were observed in the spectrum of Antares in the early 20th century and attempts were made to derive spectroscopic orbits. It became apparent that the small variations could not be due to orbital motion, and were actually caused by pulsation of the star's atmosphere. Even in 1928, it was calculated that the size of the star must vary by about 20%. Antares was first reported to have a companion star by Johann Tobias Bürg during an occultation on April 13, 1819, although this was not widely accepted and dismissed as a possible atmospheric effect. It was then observed by Scottish astronomer James William Grant FRSE while in India on 23 July 1844. It was rediscovered by Ormsby M. Mitchel in 1846, and measured by William Rutter Dawes in April 1847. In 1952, Antares was reported to vary in brightness. A photographic magnitude range from 3.00 to 3.16 was described. The brightness has been monitored by the American Association of Variable Star Observers since 1945, and it has been classified as an LC slow irregular variable star, whose apparent magnitude slowly varies between extremes of +0.6 and +1.6, although usually near magnitude +1.0. There is no obvious periodicity, but statistical analyses have suggested periods of 1,733 days or days. No separate long secondary period has been detected, although it has been suggested that primary periods longer than a thousand days are analogous to long secondary periods. Research published in 2018 demonstrated that Ngarrindjeri Aboriginal people from South Australia observed the variability of Antares and incorporated it into their oral traditions as Waiyungari (meaning 'red man'). Occultations and conjunctions Antares is 4.57 degrees south of the ecliptic, one of four first magnitude stars within 6° of the ecliptic (the others are Spica, Regulus and Aldebaran), so it can be occulted by the Moon. The occultation of 31 July 2009 was visible in much of southern Asia and the Middle East. Every year around December 2 the Sun passes 5° north of Antares. Lunar occultations of Antares are fairly common, depending on the 18.6-year cycle of the lunar nodes. The last cycle ended in 2010 and the next begins in 2023. Shown at right is a video of a reappearance event, clearly showing events for both components. Antares can also be occulted by the planets, e.g. Venus, but these events are rare. The last occultation of Antares by Venus took place on September 17, 525 BC; the next one will be November 17, 2400. Other planets have been calculated not to have occulted Antares over the last millennium, nor will they in the next millennium, as most planets stay near the ecliptic and pass north of Antares. Venus will be extremely near Antares on October 19, 2117 and every eight years thereafter through to October 29, 2157 it will pass south of the star. Illumination of Rho Ophiuchi cloud complex Antares illuminates foreground parts of the Rho Ophiuchi cloud complex. The illuminated cloud is sometimes referred to as the Antares Nebula or is otherwise identified as VdB 107, Ced 132, DG 141, LBN 1107 and Magakian 668. Stellar system α Scorpii is a double star that is thought to form a binary system. The best calculated orbit for the stars is still considered to be unreliable. It describes an almost circular orbit seen nearly edge-on, with a period of 1,218 years and a semi-major axis of about . Other recent estimates of the period have ranged from 880 years for a calculated orbit, to 2,562 years for a simple Kepler's Law estimate. Early measurements of the pair found them to be about apart in 1847–49, or apart in 1848. More modern observations consistently give separations around . The variations in the separation are often interpreted as evidence of orbital motion, but are more likely to be simply observational inaccuracies with very little true relative motion between the two components. The pair have a projected separation of about 529 astronomical units (AU) (≈ 80 billion km) at the estimated distance of Antares, giving a minimum value for the distance between them. Spectroscopic examination of the energy states in the outflow of matter from the companion star suggests that it is over beyond the primary (more than 110 billion km). Antares Antares is a red supergiant star with a stellar classification of M1.5Iab-Ib, and is indicated to be a spectral standard for that class. Due to the nature of the star, the derived parallax measurements have large errors, so that the true distance of Antares is approximately from the Sun. The brightness of Antares at visual wavelengths is about 10,000 times that of the Sun, but because the star radiates a considerable part of its energy in the infrared part of the spectrum, the true bolometric luminosity is around 100,000 times that of the Sun. There is a large margin of error assigned to values for the bolometric luminosity, typically 30% or more. There is also considerable variation between values published by different authors, for example and published in 2012 and 2013. The mass of the star has been calculated to be about , or . Comparison of the effective temperature and luminosity of Antares to theoretical evolutionary tracks for massive stars suggest a progenitor mass of and an age of 12 million years (MYr), or an initial mass of and an age of 11 to 15 MYr. Massive stars like Antares are expected to explode as supernovae. Like most cool supergiants, Antares's size has much uncertainty due to the tenuous and translucent nature of the extended outer regions of the star. Defining an effective temperature is difficult due to spectral lines being generated at different depths in the atmosphere, and linear measurements produce different results depending on the wavelength observed. In addition, Antares appears to pulsate, varying its radius by 19%. It also varies in temperature by 150 K, lagging 70 days behind radial velocity changes which are likely to be caused by the pulsations. The diameter of Antares can be measured most accurately using interferometry or observing lunar occultations events. An apparent diameter from occultations 41.3 ± 0.1 milliarcseconds has been published. Interferometry allows synthesis of a view of the stellar disc, which is then represented as a limb-darkened disk surrounded by an extended atmosphere. The diameter of the limb-darkened disk was measured as in 2009 and in 2010. The linear radius of the star can be calculated from its angular diameter and distance. However, the distance to Antares is not known with the same accuracy as modern measurements of its diameter. The Hipparcos satellite's trigonometric parallax of leads to a radius of about . Older radii estimates exceeding were derived from older measurements of the diameter, but those measurements are likely to have been affected by asymmetry of the atmosphere and the narrow range of infrared wavelengths observed; Antares has an extended shell which radiates strongly at those particular wavelengths. Despite its large size compared to the Sun, Antares is dwarfed by even larger red supergiants, such as VY Canis Majoris or VV Cephei A and Mu Cephei. Antares, like the similarly sized red supergiant Betelgeuse in the constellation Orion, will almost certainly explode as a supernova, possibly in the next ten thousand years. For a few months, the Antares supernova could be as bright as the full moon and be visible in daytime. Antares B Antares B is a magnitude 5.5 blue-white main-sequence star of spectral type B2.5V; it also has numerous unusual spectral lines suggesting it has been polluted by matter ejected by Antares. It is assumed to be a relatively normal early-B main sequence star with a mass around , a temperature around , and a radius of about . Antares B is normally difficult to see in small telescopes due to glare from Antares, but can sometimes be seen in apertures over . It is often described as green, but this is probably either a contrast effect, or the result of the mixing of light from the two stars when they are seen together through a telescope and are too close to be completely resolved. Antares B can sometimes be observed with a small telescope for a few seconds during lunar occultations while Antares is hidden by the Moon. Antares B appears a profound blue or bluish-green color, in contrast to the orange-red Antares. Etymology and mythology In the Babylonian star catalogues dating from at least 1100 BCE, Antares was called GABA GIR.TAB, "the Breast of the Scorpion". In MUL.APIN, which dates between 1100 and 700 BC, it is one of the stars of Ea in the southern sky and denotes the breast of the Scorpion goddess Ishhara. Later names that translate as "the Heart of Scorpion" include from the Arabic قَلْبُ ٱلْعَقْرَبِ . This had been directly translated from the Ancient Greek . was a calque of the Greek name rendered in Latin. In ancient Mesopotamia, Antares may have been known by various names: Urbat, Bilu-sha-ziri ("the Lord of the Seed"), Kak-shisa ("the Creator of Prosperity"), Dar Lugal ("The King"), Masu Sar ("the Hero and the King"), and Kakkab Bir ("the Vermilion Star"). In ancient Egypt, Antares represented the scorpion goddess Serket (and was the symbol of Isis in the pyramidal ceremonies). It was called tms n hntt "the red one of the prow". In Persia Antares was known as Satevis, one of the four "royal stars". In India, it with σ Scorpii and τ Scorpii were Jyeshthā (the eldest or biggest, probably attributing its huge size), one of the nakshatra (Hindu lunar mansions). The ancient Chinese called Antares 心宿二 (Xīnxiù'èr, "second star of the Heart"), because it was the second star of the mansion Xin (心). It was the national star of the Shang Dynasty, and it was sometimes referred to as () because of its reddish appearance. The Māori people of New Zealand call Antares Rēhua, and regard it as the chief of all the stars. Rēhua is father of Puanga/Puaka (Rigel), an important star in the calculation of the Māori calendar. The Wotjobaluk Koori people of Victoria, Australia, knew Antares as Djuit, son of Marpean-kurrk (Arcturus); the stars on each side represented his wives. The Kulin Kooris saw Antares (Balayang) as the brother of Bunjil (Altair). In culture Antares appears in the flag of Brazil, which displays 27 stars, each representing a federated unit of Brazil. Antares represents the state of Piauí. In Saint Seiya, the popular 1986 manga, the character Milo represents the Scorpius constellation and uses moves and attacks named after its stars - being Antares the strongest one.

Aldebaran

Aldebaran , designated α Tauri (Latinized to Alpha Tauri), is a giant star measured to be about 65 light-years from the Sun in the zodiac constellation Taurus. It is the brightest star in Taurus and generally the fourteenth-brightest star in the night sky, though it varies slowly in brightness between magnitude 0.75 and 0.95. Aldebaran is believed to host a planet several times the mass of Jupiter, named . Aldebaran is cooler than the Sun with a surface temperature of , but its radius is about 44 times the Sun's, so it is over 400 times as luminous. It spins slowly and takes 520 days to complete a rotation. The planetary exploration probe Pioneer 10 is heading in the general direction of the star and should make its closest approach in about two million years. Nomenclature The traditional name Aldebaran derives from the Arabic al Dabarān ("الدبران"), meaning "the follower", because it seems to follow the Pleiades. In 2016, the International Astronomical Union Working Group on Star Names (WGSN) approved the proper name Aldebaran for this star. Aldebaran is the brightest star in the constellation Taurus and so has the Bayer designation α Tauri, Latinised as Alpha Tauri. It has the Flamsteed designation 87 Tauri as the 87th star in the constellation of approximately 7th magnitude or brighter, ordered by right ascension. It also has the Bright Star Catalogue number 1457, the HD number 29139, and the Hipparcos catalogue number 21421, mostly seen in scientific publications. It is a variable star listed in the General Catalogue of Variable Stars, but it is listed using its Bayer designation and does not have a separate variable star designation. Aldebaran and several nearby stars are included in double star catalogues such as the Washington Double Star Catalog as WDS 04359+1631 and the Aitken Double Star Catalogue as ADS 3321. It was included with an 11th-magnitude companion as a double star as H IV 66 in the Herschel Catalogue of Double Stars and Σ II 2 in the Struve Double Star Catalog, and together with a 14th-magnitude star as β 550 in the Burnham Double Star Catalogue. Observation Aldebaran is one of the easiest stars to find in the night sky, partly due to its brightness and partly due to being near one of the more noticeable asterisms in the sky. Following the three stars of Orion's belt in the opposite direction to Sirius, the first bright star encountered is Aldebaran. The star is, by chance, in the line of sight between the Earth and the Hyades, so it has the appearance of being the brightest member of the open cluster, but the cluster that forms the bull's-head-shaped asterism is more than twice as far away, at about 150 light years. Aldebaran is 5.47 degrees south of the ecliptic and so can be occulted by the Moon. Such occultations occur when the Moon's ascending node is near the autumnal equinox. A series of 49 occultations occurred starting on 29 January 2015 and ending at 3 September 2018. Each event was visible from points in the northern hemisphere or close to the equator; people in e.g. Australia or South Africa can never observe an Aldebaran occultation since it is too far south of the ecliptic. A reasonably accurate estimate for the diameter of Aldebaran was obtained during the occultation of 22 September 1978. In the 2020s, Aldebaran is in conjunction in ecliptic longitude with the sun around May 30 of each year. With a near-infrared J band magnitude of −2.1, only Betelgeuse (−2.9), R Doradus (−2.6), and Arcturus (−2.2) are brighter at that wavelength. Observational history On 11 March AD 509, a lunar occultation of Aldebaran was observed in Athens, Greece. English astronomer Edmund Halley studied the timing of this event, and in 1718 concluded that Aldebaran must have changed position since that time, moving several minutes of arc further to the north. This, as well as observations of the changing positions of stars Sirius and Arcturus, led to the discovery of proper motion. Based on present day observations, the position of Aldebaran has shifted 7′ in the last 2000 years; roughly a quarter the diameter of the full moon. Due to precession of the equinoxes, 5,000 years ago the vernal equinox was close to Aldebaran. English astronomer William Herschel discovered a faint companion to Aldebaran in 1782; an 11th-magnitude star at an angular separation of 117″. This star was shown to be itself a close double star by S. W. Burnham in 1888, and he discovered an additional 14th-magnitude companion at an angular separation of 31″. Follow on measurements of proper motion showed that Herschel's companion was diverging from Aldebaran, and hence they were not physically connected. However, the companion discovered by Burnham had almost exactly the same proper motion as Aldebaran, suggesting that the two formed a wide binary star system. Working at his private observatory in Tulse Hill, England, in 1864 William Huggins performed the first studies of the spectrum of Aldebaran, where he was able to identify the lines of nine elements, including iron, sodium, calcium, and magnesium. In 1886, Edward C. Pickering at the Harvard College Observatory used a photographic plate to capture fifty absorption lines in the spectrum of Aldebaran. This became part of the Draper Catalogue, published in 1890. By 1887, the photographic technique had improved to the point that it was possible to measure a star's radial velocity from the amount of Doppler shift in the spectrum. By this means, the recession velocity of Aldebaran was estimated as (48 km/s), using measurements performed at Potsdam Observatory by Hermann C. Vogel and his assistant Julius Scheiner. Aldebaran was observed using an interferometer attached to the Hooker Telescope at the Mount Wilson Observatory in 1921 in order to measure its angular diameter, but it was not resolved in these observations. The extensive history of observations of Aldebaran led to it being included in the list of 33 stars chosen as benchmarks for the Gaia mission to calibrate derived stellar parameters. It had previously been used to calibrate instruments on board the Hubble Space Telescope. Physical characteristics Aldebaran is listed as the spectral standard for type K5+ III stars. Its spectrum shows that it is a giant star that has evolved off the main sequence band of the Hertzsprung–Russell diagram after exhausting the hydrogen at its core. The collapse of the centre of the star into a degenerate helium core has ignited a shell of hydrogen outside the core and Aldebaran is now on the red giant branch (RGB). The effective temperature of Aldebaran's photosphere is . It has a surface gravity of , typical for a giant star, but around 25 times lower than the Earth's and 700 times lower than the Sun's. Its metallicity is about 30% lower than the Sun's. Measurements by the Hipparcos satellite and other sources put Aldebaran around away. Asteroseismology has determined that it is about 16% more massive than the Sun, yet it shines with 518 times the Sun's luminosity due to the expanded radius. The angular diameter of Aldebaran has been measured many times. The value adopted as part of the Gaia benchmark calibration is . It is 44 times the diameter of the Sun, approximately 61 million kilometres. Aldebaran is a slightly variable star, assigned to the slow irregular type LB. The General Catalogue of Variable Stars indicates variation between apparent magnitude 0.75 and 0.95 from historical reports. Modern studies show a smaller amplitude, with some showing almost no variation. Hipparcos photometry shows an amplitude of only about 0.02 magnitudes and a possible period around 18 days. Intensive ground-based photometry showed variations of up to 0.03 magnitudes and a possible period around 91 days. Analysis of observations over a much longer period still find a total amplitude likely to be less than 0.1 magnitudes, and the variation is considered to be irregular. The photosphere shows abundances of carbon, oxygen, and nitrogen that suggest the giant has gone through its first dredge-up stage—a normal step in the evolution of a star into a red giant during which material from deep within the star is brought up to the surface by convection. With its slow rotation, Aldebaran lacks a dynamo needed to generate a corona and hence is not a source of hard X-ray emission. However, small scale magnetic fields may still be present in the lower atmosphere, resulting from convection turbulence near the surface. The measured strength of the magnetic field on Aldebaran is 0.22 Gauss. Any resulting soft X-ray emissions from this region may be attenuated by the chromosphere, although ultraviolet emission has been detected in the spectrum. The star is currently losing mass at a rate of (about one Earth mass in 300,000 years) with a velocity of . This stellar wind may be generated by the weak magnetic fields in the lower atmosphere. Beyond the chromosphere of Aldebaran is an extended molecular outer atmosphere (MOLsphere) where the temperature is cool enough for molecules of gas to form. This region lies at about 2.5 times the radius of the star and has a temperature of about . The spectrum reveals lines of carbon monoxide, water, and titanium oxide. Outside the MOLSphere, the stellar wind continues to expand until it reaches the termination shock boundary with the hot, ionized interstellar medium that dominates the Local Bubble, forming a roughly spherical astrosphere with a radius of around 1,000 AU, centered on Aldebaran. Visual companions Five faint stars appear close to Aldebaran in the sky. These double star components were given upper-case Latin letter designations more or less in the order of their discovery, with the letter A reserved for the primary star. Some characteristics of these components, including their position relative to Aldebaran, are shown in the table. Some surveys, for example Gaia Data Release 2, have indicated that Alpha Tauri B may have about the same proper motion and parallax as Aldebaran and thus may be a physical binary system. These measurements are difficult, since the dim B component appears so close to the bright primary star, and the margin of error is too large to establish (or exclude) a physical relationship between the two. So far neither the B component, nor anything else, has been unambiguously shown to be physically associated with Aldebaran. A spectral type of M2.5 has been published for Alpha Tauri B. Alpha Tauri CD is a binary system with the C and D component stars gravitationally bound to and co-orbiting each other. These co-orbiting stars have been shown to be located far beyond Aldebaran and are members of the Hyades star cluster. As with the rest of the stars in the cluster they do not physically interact with Aldebaran in any way. Planetary system In 1993 radial velocity measurements of Aldebaran, Arcturus and Pollux showed that Aldebaran exhibited a long-period radial velocity oscillation, which could be interpreted as a substellar companion. The measurements for Aldebaran implied a companion with a minimum mass 11.4 times that of Jupiter in a 643-day orbit at a separation of in a mildly eccentric orbit. However, all three stars surveyed showed similar oscillations yielding similar companion masses, and the authors concluded that the variation was likely to be intrinsic to the star rather than due to the gravitational effect of a companion. In 2015 a study showed stable long-term evidence for both a planetary companion and stellar activity. An asteroseismic analysis of the residuals to the planet fit has determined that Aldebaran b has a minimum mass of Jupiter masses, and that when the star was on the main sequence it would have given this planet Earth-like levels of illumination and therefore, potentially, temperature. This would place it and any of its moons in the habitable zone. Follow-up study in 2019 have found the evidence for planetary existence inconclusive though. Etymology and mythology Aldebaran was originally نير الضبران (Nā᾽ir al Dabarān in Arabic), meaning "the bright one of the follower". al Dabarān (الدبران) then applied to the whole of the lunar mansion containing the Hyades. It is assumed that what it was following is the Pleiades. A variety of transliterated spellings have been used, with the current Aldebaran becoming standard relatively recently. Mythology This easily seen and striking star in its suggestive asterism is a popular subject for ancient and modern myths. Mexican culture: For the Seris of northwestern Mexico, this star provides light for the seven women giving birth (Pleiades). It has three names: , , and ("star that goes ahead"). The lunar month corresponding to October is called "Aldebaran's path". Aboriginal culture: in the Clarence River of northeastern New South Wales, this star is the Ancestor Karambal, who stole another man's wife. The woman's husband tracked him down and burned the tree in which he was hiding. It is believed that he rose to the sky as smoke and became the star Aldebaran. Names in other languages In Hindu astronomy it is identified as the lunar mansion Rohini ("the red one") and as one of the twenty-seven daughters of Daksha and the wife of the god Chandra (Moon). In Ancient Greek it has been called Lampadias, literally "torch-like or -bearer". In Chinese, (), meaning Net, refers to an asterism consisting Aldebaran, ε Tauri, δ3 Tauri, δ1 Tauri, γ Tauri, 71 Tauri and λ Tauri. Consequently, the Chinese name for Aldebaran itself is (), "the Fifth Star of Net". In modern culture As the brightest star in a Zodiac constellation, it is given great significance within astrology. The name Aldebaran or Alpha Tauri has been adopted many times, including Aldebaran Rock in Antarctica United States Navy stores ship and Italian frigate Aldebaran (F 590) proposed micro-satellite launch vehicle Aldebaran French company Aldebaran Robotics fashion brand AlphaTauri Formula 1 team Scuderia AlphaTauri, previously known as Toro Rosso The star also appears in works of fiction such as Far From the Madding Crowd (1874) and Down and Out in Paris and London (1933). It is frequently seen in science fiction, including the Lensman series (1948-1954) and Fallen Dragon (2001). Aldebaran regularly features in conspiracy theories as one of the origins of extraterrestrial aliens, often linked to Nazi UFOs. A well-known example is the German conspiracy theorist Axel Stoll, who considered the star the home of the Aryan race and the target of expeditions by the Wehrmacht. The planetary exploration probe Pioneer 10 is no longer powered or in contact with Earth, but its trajectory is taking it in the general direction of Aldebaran. It is expected to make its closest approach in about two million years. The Austrian chemist Carl Auer von Welsbach proposed the name aldebaranium (chemical symbol Ad) for a rare earth element that he (among others) had found. Today, it is called ytterbium (symbol Yb).

Altair

Altair () designated α Aquilae (Latinised to Alpha Aquilae, abbreviated Alpha Aql, α Aql), is the brightest star in the constellation of Aquila and the twelfth-brightest star in the night sky. It is currently in the G-cloud—a nearby interstellar cloud, an accumulation of gas and dust. Altair is an A-type main-sequence star with an apparent visual magnitude of 0.77 and is one of the vertices of the Summer Triangle asterism (the other two vertices are marked by Deneb and Vega). It is from the Sun and is one of the most visible stars to the naked eye. Altair rotates rapidly, with a velocity at the equator of approximately 286 km/s. This is a significant fraction of the star's estimated breakup speed of 400 km/s. A study with the Palomar Testbed Interferometer revealed that Altair is not spherical, but is flattened at the poles due to its high rate of rotation. Other interferometric studies with multiple telescopes, operating in the infrared, have imaged and confirmed this phenomenon. Nomenclature α Aquilae (Latinised to Alpha Aquilae) is the star's Bayer designation. The traditional name Altair has been used since medieval times. It is an abbreviation of the Arabic phrase (the right, first word having forms from Al Nesr, ranging to An-nisr) Al-ta'ir, "". In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN, which included Altair for this star. It is now so entered in the IAU Catalog of Star Names. Physical characteristics Along with β Aquilae and γ Aquilae, Altair forms the well-known line of stars sometimes referred to as the Family of Aquila or Shaft of Aquila. Altair is a type-A main-sequence star with about 1.8 times the mass of the Sun and 11 times its luminosity. Altair rotates rapidly, with a rotational period of about 9 hours; for comparison, the equator of the Sun makes a complete rotation in a little more than 25 days. Its rapid rotation forces the star to be oblate; its equatorial diameter is over 20 percent greater than its polar diameter. Satellite measurements made in 1999 with the Wide Field Infrared Explorer showed that the brightness of Altair fluctuates slightly, varying by just a few thousandths of a magnitude with several different periods less than 2 hours. As a result, it was identified in 2005 as a Delta Scuti variable star. Its light curve can be approximated by adding together a number of sine waves, with periods that range between 0.8 and 1.5 hours. It is a weak source of coronal X-ray emission, with the most active sources of emission being located near the star's equator. This activity may be due to convection cells forming at the cooler equator. Rotational effects The angular diameter of Altair was measured interferometrically by R. Hanbury Brown and his co-workers at Narrabri Observatory in the 1960s. They found a diameter of 3milliarcseconds. Although Hanbury Brown et al. realized that Altair would be rotationally flattened, they had insufficient data to experimentally observe its oblateness. Altair was later observed to be flattened by infrared interferometric measurements made by the Palomar Testbed Interferometer in 1999 and 2000. This work was published by G. T. van Belle, David R. Ciardi and their co-authors in 2001. Theory predicts that, owing to Altair's rapid rotation, its surface gravity and effective temperature should be lower at the equator, making the equator less luminous than the poles. This phenomenon, known as gravity darkening or the von Zeipel effect, was confirmed for Altair by measurements made by the Navy Prototype Optical Interferometer in 2001, and analyzed by Ohishi et al. (2004) and Peterson et al. (2006). Also, A. Domiciano de Souza et al. (2005) verified gravity darkening using the measurements made by the Palomar and Navy interferometers, together with new measurements made by the VINCI instrument at the VLTI. Altair is one of the few stars for which a direct image has been obtained. In 2006 and 2007, J. D. Monnier and his coworkers produced an image of Altair's surface from 2006 infrared observations made with the MIRC instrument on the CHARA array interferometer; this was the first time the surface of any main-sequence star, apart from the Sun, had been imaged. The false-color image was published in 2007. The equatorial radius of the star was estimated to be 2.03 solar radii, and the polar radius 1.63 solar radii—a 25% increase of the stellar radius from pole to equator. The polar axis is inclined by about 60° to the line of sight from the Earth. Etymology, mythology and culture The term Al Nesr Al Tair appeared in Al Achsasi al Mouakket's catalogue, which was translated into Latin as Vultur Volans. This name was applied by the Arabs to the asterism of Altair, β Aquilae and γ Aquilae and probably goes back to the ancient Babylonians and Sumerians, who called Altair "the eagle star". The spelling Atair has also been used. Medieval astrolabes of England and Western Europe depicted Altair and Vega as birds. The Koori people of Victoria also knew Altair as Bunjil, the wedge-tailed eagle, and β and γ Aquilae are his two wives the black swans. The people of the Murray River knew the star as Totyerguil. The Murray River was formed when Totyerguil the hunter speared Otjout, a giant Murray cod, who, when wounded, churned a channel across southern Australia before entering the sky as the constellation Delphinus. In Chinese belief, the asterism consisting of Altair, β Aquilae and γ Aquilae is known as Hé Gǔ (; lit. "river drum"). The Chinese name for Altair is thus Hé Gǔ èr (; lit. "river drum two", meaning the "second star of the drum at the river"). However, Altair is better known by its other names: Qiān Niú Xīng ( / ) or Niú Láng Xīng (), translated as the cowherd star. These names are an allusion to a love story, The Cowherd and the Weaver Girl, in which Niulang (represented by Altair) and his two children (represented by β Aquilae and γ Aquilae) are separated from respectively their wife and mother Zhinu (represented by Vega) by the Milky Way. They are only permitted to meet once a year, when magpies form a bridge to allow them to cross the Milky Way. The people of Micronesia called Altair Mai-lapa, meaning "big/old breadfruit", while the Māori people called this star Poutu-te-rangi, meaning "pillar of heaven". In Western astrology, the star was ill-omened, portending danger from reptiles. This star is one of the asterisms used by Bugis sailors for navigation, called bintoéng timoro, meaning "eastern star". NASA announced Altair as the name of the Lunar Surface Access Module (LSAM) on December 13, 2007. The Russian-made Beriev Be-200 Altair seaplane is also named after the star. Visual companions The bright primary star has the multiple star designation WDS 19508+0852A and has several faint visual companion stars, WDS 19508+0852B, C, D, E, F and G. All are much more distant than Altair and not physically associated.

Australian Broadcasting Corporation

The Australian Broadcasting Corporation (ABC) is Australia's national broadcaster. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the Australian Broadcasting Corporation Act 1983. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled on the British Broadcasting Corporation (BBC), which is funded by a television licence, the ABC was originally financed by consumer licence fees on broadcast receivers. Licence fees were abolished in 1973 and replaced by direct government grants, as well as revenue from commercial activities related to its core broadcasting mission. The ABC adopted its current name in 1983. The ABC provides radio, television, online, and mobile services throughout metropolitan and regional Australia. ABC Radio operates four national networks, a large number of ABC Local Radio stations, several digital stations, and the international service Radio Australia. ABC Television operates five free-to-air channels, as well as the ABC iview streaming service and the ABC Australia satellite channel. News and current affairs content across all platforms is produced by the ABC News division. History Origins After public radio stations were established independently in the state capitals from 1924, a licensing scheme administered by the Postmaster-General's Department was established, allowing certain stations (with "Class A" licences") government funding, albeit with restrictions placed on their advertising content. In 1928, the government established the National Broadcasting Service to take over the 12 A-Class licences as they came up for renewal, and contracted the Australian Broadcasting Company, a private company established in 1924, to supply programs to the new national broadcaster. After it became politically unpopular to continue to allow the Postmaster-General to run the National Broadcasting Service, the government established the Australian Broadcasting Commission (ABC) on 1 July 1932, under the Australian Broadcasting Commission Act 1932. to take over the Australian Broadcasting Company and run the National Broadcasting Service. The ABC became informally referred to as "Aunty", originally in imitation of the British Broadcasting Corporation's nickname. The structure and programming was broadly modelled on the BBC, and programs not created in Australia were mostly bought in from the BBC. In 1940 one of the ABC Board's most prominent members, Dick Boyer, was appointed to the ABC, becoming chairman on 1 April 1945. Today known for the continuing series of Boyer Lectures initiated by him in 1959, he had a good but not too close with the Sir Charles Moses (general manager 1935–1965), and remained chair until his retirement in 1961. He was determined to maintain the autonomy of the ABC. War years In 1942, The Australian Broadcasting Act was passed, giving the ABC the power to decide when, and in what circumstances, political speeches should be broadcast. Directions from the minister about whether or not to broadcast any matter now had to be made in writing, and any exercise of the power had to be mentioned in the commission's annual report. 1950–2000 The ABC commenced television broadcasting in 1956. ABN-2 in Sydney was inaugurated by Prime Minister Robert Menzies on 5 November 1956, with the first broadcast presented by Michael Charlton, and James Dibble reading the first television news bulletin. Television relay facilities were not in place until the early 1960s, so news bulletins had to be sent to each capital city by teleprinter, to be prepared and presented separately in each city. In 1975, colour television was permanently introduced into Australia, and within a decade, the ABC had moved into satellite broadcasting, greatly enhancing its ability to distribute content nationally. Also in 1975, the ABC introduced a 24-hour-a-day AM rock station in Sydney, 2JJ (Double Jay), which was eventually expanded into the national Triple J FM network. A year later, a national classical music network was established on the FM band, broadcasting from Adelaide. It was initially known as ABC-FM (later ABC Classic FM) – referring both to its "fine music programming and radio frequency. ABC budget cuts began in 1976 and continued until 1998, the largest cuts (calculated by the ABC as 25% "in real terms") coming between 1985 and 1996. The Australian Broadcasting Corporation Act 1983 changed the name of the organisation to the Australian Broadcasting Corporation, effective 1 July 1983. Although funded and owned by the government, the ABC remains editorially independent as ensured by the 1983 Act. At the same time, the newly formed corporation underwent significant restructuring, including a split into separate television and radio divisions, and ABC Radio was restructured significantly again in 1985. Geoffrey Whitehead was managing director of the ABC at this time. Following his resignation in 1986, David Hill (at the time chair of the ABC Board) took over his position and local production trebled from 1986 to 1991. Live television broadcasts of selected parliamentary sessions started in 1990, and by the early 1990s, all major ABC broadcasting outlets moved to 24-hour-a-day operation. In 1991, the corporation's Sydney radio and orchestral operations moved to a new building, the ABC Ultimo Centre, in the inner-city suburb of Ultimo. In Melbourne, the ABC Southbank Centre was completed in 1994. International television service Australia Television International was established in 1993, while at the same time Radio Australia increased its international reach. Reduced funding in 1997 for Radio Australia resulted in staff and programming cuts. The ABC Multimedia Unit was established in July 1995 to manage the new ABC website, which was launched in August. The ABC was registered on the Australian Business Register as a Commonwealth Government Entity on 1 November 1999. 2000s–2010s In 2001, digital television commenced (see Online, below). At the same time, the ABC's multimedia division was renamed "ABC New Media", becoming an output division of the ABC alongside television and radio. In 2002, the ABC launched ABC Asia Pacific, the replacement for the defunct Australia Television International operated previously by the Seven Network. A digital radio service, ABC DiG, was also launched in November that year. On 8 February 2008, ABC TV was rebranded as ABC1, and a new channel for children, ABC3, was funded and announced by the Rudd government in June. A new online video-on-demand service launched in July of the same year, titled ABC iview. ABC News 24, now known as ABC News, a channel dedicated to news, launched on 22 July 2010. On 20 July 2014, ABC1 reverted to its original name of ABC TV. In November 2014, a cut of (4.6% ) to funding over the following five years together with the additional unfunded cost of the news channel meant that the ABC would have to shed about 10% of its staff, around 400 people. There were several programming changes, with regional and local programming losing out to national programs, and the Adelaide TV production studio had to close. In November 2016, the ABC announced that ABC News 24, ABC NewsRadio, as well as its online and digital news brands, would be rebranded under a unified ABC News brand, which was launched on 10 April 2017. Michelle Guthrie took over from managing director Mark Scott, who retired in April 2016. Between July 2017 and June 2018, the whole of the ABC underwent an organisational restructure, after which the Radio and Television Divisions were no longer separate entities each under a director, instead being split across several functional divisions, with different teams producing different genres of content for television, radio and digital platforms. The Entertainment & Specialist (E&S) team focussed on comedy, kids' programs, drama, Indigenous-related programs, music, other entertainment and factual content; the new ABC Specialist team created content across the arts, science, religion & ethics, education and society & culture; while the Regional & Local team focussed on regional and local content. Around 23 September 2018, Guthrie was sacked. A leadership crisis ensued after allegations arose that ABC Chair, Justin Milne, had, according to the MEAA, engaged in "overt political interference in the running of the ABC that is in clear breach of the ABC charter and the role of the chairperson" by interfering in editorial and staffing matters. After pressure for an independent inquiry or statement from Milne, or his resignation, following meetings by ABC staff in various locations, on 27 September Milne resigned. In February 2019, after the roles of ABC chair and managing director had been vacant for over four months, Ita Buttrose was named chair. Buttrose named David Anderson as managing director in May 2019. On 5 June 2019, Australian Federal Police (AFP) raided the headquarters of the ABC looking for articles written in 2017 about alleged misconduct by Australian special forces in Afghanistan, later dubbed the Afghan Files. The raid was countered by lawyers for the ABC in litigation against the AFP, challenging the examination of over 9,200 documents, including internal emails. In February 2020 the case was dismissed by the federal court. In June 2020, the AFP sent a brief of evidence to the Commonwealth Director of Public Prosecutions (CDPP), the federal public prosecutor, recommending charges be laid against journalist Dan Oakes for breaking the Afghan Files story, but in October 2020, the CDPP dropped the case. 2020s In June 2020, the ABC announced it needed to cut 229 jobs, a number of programs, and reduce its travel and production budgets after the Turnbull government's announcement of a freeze to indexation of its budget in 2018 this was estimated at the time to cost the ABC over three years, however the actual appropriation did not decrease and the ABC chair was quoted as saying it would actually increase "but by a reduced amount". In all, over a five-year period, there were 737 redundancies, a further 866 resignations and 203 retirements, but the total number of staff only fell by 313 due to the ABC hiring 650 staff over that period. In June 2021, the ABC announced its plan to move around 300 staff to offices in Parramatta, in a plan which would see 75% of journalists and producers moving out of the Ultimo building by 2025 in order to reduce costs. Rental from some of the vacant space in the city centre would earn additional income to offset the ongoing effects of the significant funding cuts since 2014 and the recent indexation freeze. In December 2021 the ABC announced that, in addition to the 83 additional positions already established, it was to create an additional "50-plus" new jobs in regional Australia as a result of commercial agreements with digital platforms flowing from the Morrison government's News Media Bargaining Code. Lissajous curve logo The ABC logo is one of the most recognisable logos in Australia. In the early years of television, the ABC had been using Lissajous curves as fillers between programmes. In July 1963, the ABC conducted a staff competition to create a new logo for use on television, stationery, publications, microphone badges and ABC vehicles. In 1965, ABC graphics designer Bill Kennard submitted a design representing a Lissajous display, as generated when a sine wave signal is applied to the "X" input of an oscilloscope and another at three times the frequency at the "Y" input. The letters "ABC" were added to the design and it was adopted as the ABC's official logo. Kennard was presented with £25 (about AU$715 in 2021) for his design. On 19 October 1974, the Lissajous curve design experienced its first facelift with the line thickened to allow for colour to be used. It would also be treated to the 'over and under' effect, showing the crossover of the line in the design. This logo would be served as the longest-running design with a lifespan of 44 years and 28 on its first on-air run. To celebrate its 70th anniversary on 1 July 2002, the ABC adopted a new logo, which was created by (Annette) Harcus Design in 2001. This logo used a silver 3D texture but the crossover design was left intact and was then used across the ABC's media outlets. After the on-air revival of the 1974 logo since 2014, the ABC gradually reinstated the classic symbol. The most recent change happened in February 2018 where announced a new logotype and brand positioning under its tagline, Yours. The 2002 silver logo is no longer in use by the corporation. Governance and structure The operations of the ABC are governed by a board of directors, consisting of a managing director, five to seven directors, and until 2006, a staff-elected director. The managing director is appointed by the board for a period of up to five years, but is eligible for renewal. The authority and guidelines for the appointment of directors is provided for in the Australian Broadcasting Corporation Act 1983. Appointments to the ABC Board made by successive governments have often resulted in criticism of the appointees' political affiliation, background, and relative merit. Past appointments have associated directly with political parties – five of fourteen appointed chairmen have been accused of political affiliation or friendship, include Richard Downing and Ken Myer (both of whom publicly endorsed the Australian Labor Party at the 1972 election), as well as Sir Henry Bland. David Hill was close to Neville Wran, while Donald McDonald was considered to be a close friend of John Howard. From 2003 the Howard government made several controversial appointments to the ABC Board, including prominent ABC critic Janet Albrechtsen, Ron Brunton, and Keith Windschuttle. During their 2007 federal election campaign, Labor announced plans to introduce a new system, similar to that of the BBC, for appointing members to the board. Under the new system, candidates for the ABC Board would be considered by an independent panel established "at arm's length" from the Communications Minister. If the minister chose someone not on the panel's shortlist, they would be required to justify this to parliament. The ABC chairman would be nominated by the prime minister and endorsed by the leader of the opposition. A new merit-based appointment system was announced on 16 October 2008, in advance of the new triennial funding period starting in 2009. board members are: As of July 2020 there were 3,730 employees, down from 4,649 in 2019. Funding The ABC is primarily funded by the Australian government, in addition to some revenue received from commercial offerings and its retail outlets. The ABC's funding system is set and reviewed every three years. Until 1948, the ABC was funded directly by radio licence fees; amendments were also made to the Australian Broadcasting Act that meant the ABC would receive its funding directly from the federal government. Licence fees remained until 1973, when they were abolished by the Whitlam Labor government, on the basis that the near-universality of television and radio services meant that public funding was a fairer method of providing revenue for government-owned radio and television broadcasters. In 2014, the ABC absorbed A$254 million in federal budget deficits. Since the 2018 budget handed down by then-Treasurer Scott Morrison, the ABC has been subject to a pause of indexation of operation funding, saving the federal government a total of A$83.7 million over 3 years. In fiscal year 2016–17, the ABC received A$861 million in federal funding, which increased to $865 million per year from 2017 to 2018 to 2018–19, representing a cut in funding of $43 million over three years when accounting for inflation. In 2019–20, the federal budget forecast funding of $3.2 billion over three years ($1.06 billion per year) for the ABC. The Enhanced Newsgathering Fund, a specialised fund for regional and outer-suburban news gathering set up in 2013 by the Gillard Government, currently sits at $44 million over three years, a reduction of $28 million per year since the 2016 Australian federal election. This came after speculation that the fund would be removed, to which ABC Acting managing director David Anderson wrote to Communications Minister Mitch Fifield expressing concerns. However, despite the cuts made by Prime Minister Tony Abbott and Communications Minister Malcolm Turnbull and the freeze introduced by Prime Minister Malcolm Turnbull and Communications Minister Mitch Fifield, the ABC itself has published financial data that shows an increase in the taxpayer appropriation to the ABC of 10% in real terms (i.e. above inflation) between 1998 and 2021. The term "where your 8 cents a day goes", coined in the late 1980s during funding negotiations, is often used in reference to the services provided by the ABC. It was estimated that the cost of the ABC per head of population per day was 7.1 cents a day, based on the corporation's 2007–08 "base funding" of . Services Radio The ABC operates 54 local radio stations, in addition to four national networks and international service Radio Australia. In addition, DiG Radio (rebranded as Double J in 2014) launched on digital platforms in 2002, and later spinning off ABC Country and ABC Jazz. ABC Local Radio is the corporation's flagship radio station in each broadcast area. There are 54 individual stations, each with a similar format consisting of locally presented light entertainment, news, talk back, music, sport and interviews, in addition to some national programming such as AM, PM, The World Today, sporting events and Nightlife. the ABC operates 15 radio networks, variously available on AM and FM as well as on digital platforms and the internet.

There is also ABC Radio Australia, the international radio station of the ABC (see below). Television The ABC operates five national television channels: ABC TV (formerly ABC1), the corporation's original television service, receives the bulk of funding for television and shows first-run comedy, drama, documentaries, and news and current affairs. In each state and territory a local news bulletin is shown at 7pm nightly. ABC TV Plus (formerly ABC2 and then ABC Comedy), launched in 2005, shows comedic content in addition to some repeats from ABC TV of which the amount has decreased gradually since ABC TV Plus's inception. It is not a 24-hour channel, but is broadcast daily from 7pm to around 3am the following night. The channel shares airspace with the ABC Kids programming block from 5am to 7:30 pm. ABC Me (originally ABC3) became a fully fledged channel on 4 December 2009, but has been part of the electronic guide line-up since 2008, broadcasting an ABC1 simulcast until 4 December 2009, then an ABC Radio simulcast and teaser graphic until its official launch. It is broadcast from 6am to around 10pm on weekdays and 6am to 2am the next day on weekends, and consists of a broad range programmes aimed at a young audience aged 6–15, with a core demographic of 8–12. ABC Kids (originally ABC For Kids on 2 and ABC 4 Kids) is a new preschool children's block featuring children's programming aimed at the 0 to 5 age groups. ABC Kids broadcasts during ABC TV Plus downtime, from 5am to 7:30 pm daily. ABC News (originally ABC News 24), a 24-hour news channel, featuring the programming from ABC News and Current Affairs, selected programs from the BBC World News channel, coverage of the Federal Parliament's Question Time, documentaries and factual, arts programming and state or national election coverage. Although the ABC's headquarters in Sydney serve as a base for program distribution nationally, ABC Television network is composed of eight state- and territory-based stations, each based in their respective state capital and augmented by repeaters: ABN (Sydney) ABV (Melbourne) ABQ (Brisbane) ABS (Adelaide) ABW (Perth) ABT (Hobart) ABC (Canberra) ABD (Darwin) The eight ABC stations carry opt outs for local programming. In addition to the nightly 7pm news, the stations also broadcast weekly state editions of 7.30 on Friday evenings (until 5 December 2014), state election coverage and in most areas, live sport on Saturday afternoons. There is also ABC Australia, the international TV service of the ABC (see below). Online and digital ABC Online is the name given to the online services of the ABC, which have evolved to cover a large network of websites including those for ABC News, its various television channels, ABC radio; podcasts; SMS, mobile apps and other mobile phone services; vodcasts and video-on-demand through ABC iView. The official launch of ABC Online, then part of the ABC's Multimedia Unit, was on 14 August 1995, charged with developing policy for the ABC's work in web publishing. At first it relied upon funding allocation to the corporation's TV and radio operations, but later began to receive its own. The ABC provided live, online election coverage for the first time in 1996, and limited news content began to be provided in 1997. This unit continued until 2000, when the New Media division was formed, bringing together the ABC's online output as a division similar to television or radio. In 2001 the New Media division became New Media and Digital Services, reflecting the broader remit to develop content for digital platforms such as digital television, becoming an "output division" similar to Television or Radio. In addition to ABC Online, the division also had responsibility over the ABC's two digital television services, Fly TV and the ABC Kids channel, until their closure in 2003. ABC TV Plus, a digital-only free-to-air television channel, launched on 7 March 2005. Unlike its predecessors the new service was not dependent on government funding, instead running on a budget of per year. Minister for Communications Helen Coonan inaugurated the channel at Parliament House three days later. Genre restrictions limiting the types of programming the channel could carry were lifted in October 2006 – ABC2 was henceforth able to carry programming classified as comedy, drama, national news, sport, and entertainment. In conjunction with the ABC's radio division, New Media and Digital Services implemented the ABC's first podcasts in December 2004. By mid-2006 the ABC had become an international leader in podcasting with over fifty podcast programmes delivering hundreds of thousands of downloads per week, including trial video podcasts of The Chaser's War on Everything and jtv. In February 2007, the New Media & Digital Services division was dissolved and divided up among other areas of the ABC. It was replaced by a new Innovation division, to manage ABC Online and investigate new technologies for the ABC. In 2008, Crikey reported that certain ABC Online mobile sites in development were planned to carry commercial advertising. Screenshots, developed in-house, of an ABC Grandstand sport page include advertising for two private companies. Media Watch later revealed that the websites were to be operated by ABC Commercial and distinguished from the main, advertising-free, mobile website by a distinct logo. In 2015 the Innovation Division was replaced with the Digital Network Division. Angela Clark was head from 2012 until at least the end of financial year 2015/6, but by 2017 she was gone, and the Digital Network fell into the Technology division under the Chief Technology Officer. In May 2017, Helen Clifton was appointed to the new role of Chief Digital and Information Officer, which continues . In December 2019, a refreshed ABC homepage was launched. ABC News is one of Australia's largest and most-visited web sites; from its position as 11th most popular in the country in 2008, in recent years up to 2021 it has maintained top position in the rankings. International ABC International is responsible for its international operations, which include the internationally broadcast Radio Australia, the Asia-Pacific TV channel ABC Australia, and its ABC International Development (ABCID) branch. In June 2012 Lynley Marshall, former head of ABC Commercial, was appointed CEO of ABC International, filling a role left empty by the retirement of Murray Green. At the time, it was intended that Radio Australia, Australia Network and ABC News 24 would work together more closely ABC International was at this time a division of the ABC, but it has not been represented as a separate division in the organisational structure of the ABC since 2016,<ref after Marshall's departure in February 2017. There were fears of job losses in the division after the huge budget cuts in 2014, as well as an earlier termination of a contract with the Department of Foreign Affairs, one year into the 10-year contract. On 24 May 2021, Claire Gorman was appointed to an expanded role to manage both the International Strategy and the International Development teams. ABC Australia is an international satellite television service operated by the Australian Broadcasting Corporation, funded by advertising and grants from the Department of Foreign Affairs and Trade. Aimed at the Asia-Pacific region, the service broadcasts a mixture of English language programming, including general entertainment, sport, and current affairs. Radio Australia is an international satellite and internet radio service with transmissions aimed at South-East Asia and the Pacific Islands, although its signals are also audible in many other parts of the world. It features programmes in various languages spoken in these regions, including Mandarin, Indonesian, Vietnamese, Khmer and Tok Pisin. Before 31 January 2017 Radio Australia broadcast short-wave radio signals. Radio Australia bulletins are also carried on WRN Broadcast, available via satellite in Europe and North America. ABC International Development, or ABCID, is a media development unit that promotes public interest journalism and connects with local media in the region. ABCID employs local people in Papua New Guinea and many Pacific countries. The team "provides expertise, training, technical and program support to partner organisations", by working with a variety of organisations, including international development donors, for example through the through the Pacific Media Assistance Scheme (PACMAS). ABC Commercial The commercial arm of the ABC was established in 1974 under the name Enterprises as a self-funding unit, marketing products relating to the ABC's activities. It was renamed in 2007 to ABC Commercial, The aim of ABC Commercial was "to create, market and retail high quality consumer products which reflect and extend the scope of the ABC’s activities". At this time it comprised the ABC Shop, ABC Consumer Publishing and Content Sales, ABC Resource Hire, and ABC Content Services (Archives). ABC Commercial was registered as a business name under Australian Broadcasting Corporation in April 2007 and continues to exist . It includes ABC Music, a leading independent record label; ABC Events, which stages concerts and other events; and publishing and licensing activities by ABC Books, ABC Audio, ABC Magazines and ABC Licensing. ABC Shop Online was wound up at the end of 2018, along with the in-store ABC Centres. In early 2019, ABC Commercial split from the Finance division and became an independent business unit of the ABC. In the financial year 2018–2019, ABC Commercial turned a profit of , which was invested in content production. The ABC Studios and Media Production hires out some of the ABC studios and sound stages, operating as part of ABC Commercial. The studios for hire are in Sydney (Studios 21, 22, 16), Melbourne (31), Adelaide (51B) and Perth (61). Orchestras Up until the installation of disc recording equipment in 1935, all content broadcast on the ABC was produced live, including music. For this purpose, the ABC established broadcasting orchestras in each state, and in some centres also employed choruses and dance bands. This became known as the ABC Concert Music Division, which was controlled by the Federal Director of Music – the first of whom was W. G. James. In 1997, the ABC divested all ABC orchestras from the Concerts department of the ABC into separate subsidiary companies, allied to a service company known as Symphony Australia, and on 1 January 2007 the orchestras were divested into independent companies. The six state orchestras are: Adelaide Symphony Orchestra Melbourne Symphony Orchestra Queensland Symphony Orchestra Sydney Symphony Orchestra Tasmanian Symphony Orchestra West Australian Symphony Orchestra ABC Friends ABC Friends, formerly Friends of the ABC (FABC), consists of independent organisations in each state and territory, under an umbrella organisation established in December 2016, ABC Friends National Inc. In 1976, three independent groups were formed: Aunty's Nieces and Nephews in Melbourne, Friends of the ABC (NSW) Inc. (now ABC Friends NSW & ACT) and Friends of the ABC (SA) (since 2007/2008, ABC Friends SA/NT). The groups were formed by citizens who were concerned about government threats to make deep cuts to the ABC's budget. Historian Ken Inglis wrote that “The Friends were in the line of those people who had affirmed over the years that the ABC was essential to the nation”. Over the years, independent state organisations were established, run by committees, and in January 2014 the name of each was changed to ABC Friends. The objectives of ABC Friends National are stated as follows: Criticism and controversy Independence and impartiality Under the Australian Broadcasting Corporation Act 1983, the ABC Board is bound to "maintain the independence and integrity of the Corporation" and to ensure that "the gathering and presentation by the Corporation of news and information is accurate and impartial according to the recognized standards of objective journalism". In relation to impartiality and diversity of perspectives, the current ABC editorial policy requires of the broadcaster that: As a publicly-funded broadcaster, the ABC is expected not to take editorial stances on political issues, and is required under its charter enshrined in legislation to present a range of views with impartiality. Over the decades, accusations of "bias" at the ABC have arisen at different times, and various inquiries have been undertaken. Perceived bias External critics have complained in particular of left-wing political bias at the broadcaster, citing a prominence of Labor Party-connected journalists hosting masthead political programs or a tendency to favour "progressive" over "conservative" political views on issues such as immigration, asylum seekers, the republicanism, multiculturalism, Indigenous reconciliation, feminism, environmentalism, and same-sex marriage. In December 2013, former judge and ABC chair James Spigelman announced that four independent audits would be conducted each year in response to the allegations of bias in the reporting of news and current affairs. ABC Friends have observed that "Most of the complaints about bias in the ABC have come from the government of the day – Labor or Liberal. Significantly both parties have been far less hostile to the ABC when in opposition". Conservative commentators such as Andrew Bolt, Tim Blair, and Gerard Henderson have regularly accused the ABC of a left-wing bias. ABC journalist Annabel Crabb said in 2015 that the organisation gives "voices to Australians who otherwise wouldn't be heard, on topics that are too uncommercial or too remote or too hard to be covered by anyone else, broadcasting into areas from which others have long withdrawn resources". Journalist Tom Switzer commented that there was entrenched but unintentional bias. ABC journalist turned NSW Liberal MLA Pru Goward said of the organisation: "I have no doubt there was left-wing bias, I certainly thought it when I was there", while ABC journalist turned Federal Labor politician Maxine McKew said there was no left-wing bias. Former ABC Chair and conservative commentator Maurice Newman told Sky News Australia that "the ABC bias is absolutely palpable". Former Prime Minister of Australia Malcolm Turnbull commented in 2018 that some journalists and programs had shown a left-wing bias. In a March 2016 interview with ABC managing director Mark Scott, Media Watch host Paul Barry examined the question of perceptions of left-wing bias at the ABC. Scott noted that while perhaps the ABC was more concerned about gay marriage than about electricity prices, he did not accept the criticism of bias because "a lot of that criticism comes from right-wing commentators and they wonder where are the strong right-wing commentators on the ABC. We don't do that kind of journalism. We don't ask questions about our journalists' voting pattern and where their ideology are. We look at the journalism that they put to air and we have strong editorial standards...". Following the interview, Andrew Bolt wrote "How can the man heading our biggest media organisation be so blind to the ABC's unlawful and dangerous Leftist bias?" while former Media Watch host Jonathan Holmes wrote that ABC Radio needs to "try harder" at avoiding left-wing bias among its capital city radio hosts. An interview by ABC presenter Joe O'Brien with Lyle Shelton in 2017 was the subject of a complaint by the Australian Christian Lobby. Bringing up Ian Thorpe's swimming achievements, O'Brien asked Shelton "what right do you have to participate in that joy, and take national pride in those achievements, if you now deny him the right to feel like an equal and experience the joy of marriage?" In rejecting any perceived bias, the ABC said "It was a 'devil's advocate' question and not inconsistent with standards". Reviews and investigations Reviews of the ABC are regularly commissioned and sometimes not released. Both internal and external research has been conducted on the question of bias at the ABC. These include the following: A 2004 Roy Morgan media credibility survey found that journalists regarded ABC Radio as the most accurate news source in the country and the ABC as the second "most politically biased media organisation in Australia". A 2013 University of the Sunshine Coast study of the voting intentions of journalists found that 73.6% of ABC journalists supported Labor or The Greens – with 41% supporting the Greens (whereas only around 10% of people in the general population voted Green). At the 2016 federal election, a study commissioned by the ABC and conducted by Isentia compiled share-of-voice data and found that the ABC devoted 42.6% of election coverage to the Coalition government (this compares to the 42.04% vote received by the Coalition in the House of Representatives (HOR)), 35.9% to the Labor opposition (34.73% HOR), 8% to The Greens(10.23% HOR), 3.1% to independents (1.85% HOR), 2.2% to the Nick Xenophon Team (1.85% HOR) and 8.1% to the rest. However, the ABC itself notes the "significant limitations around the value of share of voice data" as "duration says nothing about tone or context". In December 2020, the Board commissioned its 19th editorial review by an independent reviewer, which found that the ABC's news coverage of lead-up to the 2019 Australian election was "overwhelmingly positive and unbiased", although it also found that specific episodes of The Drum and Insiders reflected too narrow a range of viewpoints. The government forced the publication of the report after Coalition senator James McGrath raised a motion in the Senate, which led to ABC Chair Ita Buttrose and managing director David Anderson writing to the president of the Senate, Scott Ryan, to express their concerns about the use of the such powers, which went against the public interest. Relationships with government 1990s to 2013 Labor Prime Minister Bob Hawke considered the ABC's coverage of the 1991 Gulf War to be biased. In 1996, conservative Opposition Leader John Howard refused to have Kerry O'Brien of the ABC moderate the television debates with Labor Prime Minister Paul Keating because Howard saw O'Brien as biased against the Coalition. During the subsequent Howard Government years, ABC TV's masthead political programs were anchored by journalists with Labor affiliations: the 7.30 Report was hosted by former Whitlam staffer Kerry O'Brien; the Insiders program by former Hawke staffer Barrie Cassidy and the Lateline program by Maxine McKew, who went on to defeat Howard as the Labor candidate for the seat of Bennelong in 2007, at the same time as ABC Sydney News weatherman Mike Bailey ran for Labor against Liberal minister Joe Hockey. In the subsequent Kevin Rudd-Julia Gillard period, Cassidy retained his position at Insiders, while O'Brien shifted to host Four Corners in 2011. Chris Uhlmann, husband of Labor MP Gai Brodtmann, was appointed as co-host of the 7.30 current affairs program, and Sydney ABC News anchor Juanita Phillips began a relationship with Labor's Minister for Climate Change, Greg Combet. 2013–present Liberal Prime Minister Tony Abbott perceived the ABC to be left wing and hostile to his government, while his successor Malcolm Turnbull enjoyed better relations with the national broadcaster. When the ABC co-published Edward Snowden's stolen documents purportedly revealing Australian spy agency activities overseas, Abbott told 2GB radio: "people feel at the moment that the ABC instinctively takes everyone's side but Australia's". He reportedly called the Q&A program a "lefty lynch mob". Abbott denounced the program for inviting Zaky Mallah, a man convicted of threatening Commonwealth officials, to participate in questioning one of his ministers. Abbott initiated a brief ministerial boycott of the Q&A program afterwards. The broadcaster was critical of Abbott when he broke an election-eve promise not to make cuts to the ABC as part of his "budget repair" program. In early 2015, an internal ABC review of its coverage of Joe Hockey's first Budget criticised the post-budget interviews by 7:30 and Lateline, finding that the interviewers had given the impression of bias. When Abbott lost the leadership to the less conservative Turnbull in the September 2015 Liberal leadership spill, the hosts of the ABC's political programs spoke in favour of Abbott's demise. Kerry O'Brien and Barrie Cassidy, hosts respectively of the ABC's flagship weekly current affairs programs Four Corners and Insiders, welcomed the replacement of Abbott by Turnbull, as did ABC radio commentators Fran Kelly Paul Bongiorno and Amanda Vanstone. Fairfax and News Limited reported that Leigh Sales, the host of 7.30 gave Turnbull an unusually warm first interview following his toppling of Abbott. When Turnbull lost the leadership after a conservative challenge in August 2018, the hosts of the ABC's political programs denounced the change. The 7 pm News political correspondent Andrew Probyn, who had been censured by ACMA earlier in the year for biased reporting against Abbott, said the removal of Turnbull was about "vengeance pure and simple". Earlier in the year. Insiders''' Barrie Cassidy called it "insanity and madness". 7:30 Chief Political Correspondent Laura Tingle was selected by Turnbull first among a handful of journalists to ask questions at his final press conference. She said "one of frustrations that voters have had with your prime ministership is the sense that you have conceded too regularly to the conservatives" Vanstone called the challenge "disgraceful". In 2021, the former Attorney-General in the Morrison government, Christian Porter, sued the ABC for defamation over an article written by Louise Milligan about an historic rape allegation. Porter discontinued the action in May 2021. In May 2021, ABC management spiked a Four Corners story about the relationship between Prime Minister Scott Morrison and a supporter of QAnon. Specific topics Same-sex marriage In 2017, ABC TV and radio hosts advocated strongly in support of same-sex marriage, upon which the wider Australian community and political parties were divided. When the Turnbull government announced plans for a postal plebiscite on the issue, advocacy for change continued, prompting a call for restraint from the ABC's editorial policy manager Mark Maley. Australia Day The ABC was criticised for giving undue support to opposition to Australia Day being held on 26 January, after Triple J, ABC's youth radio network, announced in November 2017 that it would no longer play its "Hottest 100" Australian music list on Australia Day, choosing instead to broadcast the playlist on the fourth weekend in January. It had taken the decision after extensive consultation with a variety of people, including "musicians, community leaders, representative groups, triple j staff, ABC groups, and a wide range of Aboriginal and Torres Strait Islander media, language groups, and many of the Indigenous artists featured on triple j", as well as an opinion poll of its listeners, Federal Communications Minister Mitch Fifield said "Australia Day is our national day. The ABC should honour it and not mess with the Hottest 100".Triple J moves Hottest 100 from Australia Day after protests ; The Guardian; 27 November 2017 Justin Milne, ABC Chair at the time, held a meeting trying to convince the board to overrule Triple J's decision. In June 2018, an opinion piece by writer, historian and heritage consultant Aron Paul suggesting the date should be moved to 1 January, as this was the date that the Commonwealth of Australia was created, was published on the ABC website. The Catholic Church and George Pell The ABC's coverage of the issue of sexual abuse in the Catholic Church has received praise and criticism. The Melbourne Press Club presented the 2016 Quill for Coverage of an Issue or Event for the report George Pell and Sexual Abuse in the Catholic Church, and the 2016 Golden Quill award to Louise Milligan and Andy Burns for their extensive coverage of Cardinal George Pell's evidence given at the Royal Commission into Institutional Responses to Child Sexual Abuse. The ABC Media Watch program of 20 April 2020 noted that the ABC had been accused of leading a "witch hunt" against Cardinal Pell. Media Watch reported that, following his acquittal, Pell said the ABC gave an "overwhelming presentation of one view and only one view". Media Watch also canvassed other criticisms including from The Australian newspaper's editor-at-large Paul Kelly, who charged the ABC with having run a "sustained campaign against Pell". Media Watch also offered criticism of its own, noting Louise Milligan and the Four Corners program had failed to canvass any of Pell’s defence from the trial and "lined up witnesses condemning Pell", while social media commentary by Barrie Cassidy and Quentin Dempster had undermined the presumption of innocence. Margaret Simons similarly noted in The Guardian that "there has been some social media activity by ABC journalists that looks very much like lobbying against Pell..." Initial reports into the accusations against Pell were broken by the Herald Sun in February 2016, with the ABC first covering the story in July that year on 7.30, featuring two self-described victims. Pell declined an invitation to participate, issuing a statement instead. The ABC News and Current Affairs programs provided coverage of the investigation and trial of Pell, in particular Four Corners in March 2019 and the series Revelation in 2020. Pell was made aware of the programs before they were broadcast and given the opportunity to respond to them, but did not take up the offer. In a later review of the programming, the ABC noted that "many of the Cardinal’s most prominent supporters [had] regularly appeared on major ABC programs, and the ABC’s coverage [had] consistently included a wide diversity of voices, accurate news and authoritative analysis of the many complex legal issues raised by the case". The ABC's coverage of the Catholic Church has been criticised. The Archbishop of Brisbane, Mark Coleridge, condemned the ABC in 2017 for an "antagonistic, one-sided narrative" of the Catholic Church following a report on domestic violence within Christian churches. ABC TV's Media Watch found that the story had “misrepresented” research used by the journalists, which a spokesperson for the ABC said was the result of an oversight. Gerard Henderson of the Sydney Institute wrote in Quadrant in November 2018 that "The ABC's focus on historic child sexual abuse in the Catholic Church stands in contrast to its failure to cover the public broadcaster’s own history in this area". After the conviction of Pell by a jury in 2019, journalist Paul Kelly wrote in The Australian that media assaults on Pell led by the ABC had contributed to an intense and unjustified public hatred of the Catholic leader, and prejudicial environment in which to conduct a trial. He also referred to the earlier conviction and later acquittal of Adelaide archbishop Phillip Wilson in 2018. After the unanimous acquittal of Pell by the High Court of Australia in 2020, Pell and various commentators accused the ABC of sustained bias against him and of "abuse of power". The ABC conducted an editorial and legal review of its coverage where it rejected the accusation of bias, and defended its reporting of Pell as having been "without fear or favour".The Australian published many criticisms of the ABC's coverage of the Pell trial. Australian Catholic University vice-chancellor Greg Craven on 8 April 2020 accused the ABC of creating "an atmosphere conducive to a conviction". In the 11 April 2020 issue, both Paul Kelly and Gerard Henderson criticised the ABC for its coverage of the Pell trial. On 16 April 2020, Greg Sheridan criticised the presentation of Milligan as an impartial reporter, as she had previously written a book damning Pell. Environmentalism Planet Slayer was an ABC website run by scientist Bernie Hobbs to teach children about the environment in around 2008/9. It included a "Greenhouse Calculator" which aimed to help children to work out their carbon footprint by providing an estimate of the age a person needs to die if they are not to use more than their fair share of the Earth's resources. Victorian Liberal senator Mitch Fifield criticised a cartoon series on the site for portraying those who eat meat, loggers, and workers in the nuclear industry as "evil". ABC managing director Mark Scott said the site was not designed to offend anyone, but instead have children think about environmental issues. ABC journalists in politics A number of former journalists and presenters have moved from positions at the ABC to politics. State Labor premiers and chief ministers Bob Carr, Alan Carpenter, and Clare Martin are all former ABC journalists. Other ABC journalists who stood as Labor candidates include Mary Delahunty, Maxine McKew, Mike Bailey, Ian Baker, Leon Bignell, John Bowler, Bob Debus, Malarndirri McCarthy, Frank McGuire, Neville Oliver and Diana Warnock. Kerry O'Brien was press secretary to Labor prime minister Gough Whitlam and Labor deputy leader Lionel Bowen and Barrie Cassidy was press secretary to Labor prime minister Bob Hawke. Radio National's Phillip Adams is a former member of the Communist Party of Australia and the Labor Party, and Melbourne ABC radio's Jon Faine is a former member of the Labor Party. On the Coalition side of politics, Pru Goward has served as a Minister in the NSW state Liberal Government, Rob Messenger, Peter Collins, Eoin Cameron, Scott Emerson and Sarah Henderson all held, or hold, positions at the ABC. Radio National's Counterpoint program is hosted by former Liberal minister Amanda Vanstone, who describes herself as "liberal" rather than "conservative". Research undertaken by the broadcaster in 2007 indicated that out of a total of 19 former employees moving into party political positions, 10 had joined the Labor Party and 9 the Liberal Party.

Alexandria

Alexandria ( or ; ; ; ; Alexándria) is the third-largest city in Egypt after Cairo and Giza, the ninth-largest city in Africa, and a major economic centre. Called the "Bride of the Mediterranean" by locals, Alexandria is the largest city on the Mediterranean, the fourth-largest city in the Arab world, and the ninth-largest urban area in Africa as well as the 79th largest urban area by population on Earth. The city extends about at the northern coast of Egypt along the Mediterranean Sea. Alexandria is a popular tourist destination, and an important industrial centre due to its natural gas and oil pipelines from Suez. Alexandria was founded in by Alexander the Great in the vicinity of an Egyptian settlement named Rhacotis (that became the Egyptian quarter of the city). Alexandria grew rapidly, becoming a major centre of Hellenic civilisation, and replacing Memphis as Egypt's capital during the reign of the Ptolemaic pharaohs who succeeded Alexander. It retained this status for almost a millennium, through the period of Roman and Eastern Roman (Byzantine) rule until the Muslim conquest of Egypt in 641 AD, when a new capital was founded at Fustat (later absorbed into Cairo). Alexandria was best known for the Lighthouse of Alexandria (Pharos), one of the Seven Wonders of the Ancient World, its Great Library (the largest in the ancient world), and the Necropolis, one of the Seven Wonders of the Middle Ages. Alexandria was the intellectual and cultural centre of the ancient Mediterranean for much of the Hellenistic age and late antiquity. It was at one time the largest city in the ancient world before being eventually overtaken by Rome. The city was a major centre of early Christianity, and was the centre of the Patriarchate of Alexandria, which was one of the major centres of Christianity in the Eastern Roman Empire. In the modern world, the Coptic Orthodox Church, and the Greek Orthodox Church of Alexandria both lay claim to this ancient heritage. By the time of the Arab conquest of Egypt in 641 AD, the city had already been largely plundered and lost its significance before re-emerging in the modern era. From the late 18th century, Alexandria became a major centre of the international shipping industry and one of the most important trading centres in the world, both because it profited from the easy overland connection between the Mediterranean Sea and the Red Sea, and the lucrative trade in Egyptian cotton. History Ancient era Recent radiocarbon dating of seashell fragments and lead contamination show human activity at the location during the period of the Old Kingdom (27th–21st centuries BC) and again in the period 1000–800 BC, followed by the absence of activity thereafter. From ancient sources it is known there existed a trading post at this location during the time of Rameses the Great for trade with Crete, but it had long been lost by the time of Alexander's arrival. A small Egyptian fishing village named Rhakotis (Egyptian: rꜥ-qdy.t, 'That which is built up') existed since the 13th century BC in the vicinity and eventually grew into the Egyptian quarter of the city. Just east of Alexandria (where Abu Qir Bay is now), there were in ancient times marshland and several islands. As early as the 7th century BC, there existed important port cities of Canopus and Heracleion. The latter was recently rediscovered under water. Alexandria was founded by Alexander the Great in April 331 BC as (Alexandreia). After he captured the Egyptian Satrapy from the Persians, Alexander wanted to build a large Greek city on Egypt's coast that would bear his name. He chose the site of Alexandria, envisioning the building of a causeway to the nearby island of Pharos that would generate two great natural harbours. Alexandria was intended to supersede the older Greek colony of Naucratis as a Hellenistic centre in Egypt, and to be the link between Greece and the rich Nile valley. A few months after the foundation, Alexander left Egypt and never returned to the city during his life. After Alexander's departure, his viceroy Cleomenes continued the expansion. The architect Dinocrates of Rhodes designed the city, using a Hippodamian grid plan. Following Alexander's death in 323 BC, his general Ptolemy Lagides took possession of Egypt and brought Alexander's body to Egypt with him. Ptolemy at first ruled from the old Egyptian capital of Memphis. In 322/321 BC he had Cleomenes executed. Finally, in 305 BC, Ptolemy declared himself Pharaoh as Ptolemy I Soter ("Savior") and moved his capital to Alexandria. Although Cleomenes was mainly in charge of overseeing Alexandria's early development, the Heptastadion and the mainland quarters seem to have been primarily Ptolemaic work. Inheriting the trade of ruined Tyre and becoming the centre of the new commerce between Europe and the Arabian and Indian East, the city grew in less than a generation to be larger than Carthage. In one century, Alexandria had become the largest city in the world and, for some centuries more, was second only to Rome. It became Egypt's main Greek city, with Greek people from diverse backgrounds. Alexandria was not only a centre of Hellenism, but was also home to the largest urban Jewish community in the world. The Septuagint, a Greek version of the Tanakh, was produced there. The early Ptolemies kept it in order and fostered the development of its museum into the leading Hellenistic centre of learning (Library of Alexandria, which faced destruction during Caesar's siege of Alexandria), but were careful to maintain the distinction of its population's three largest ethnicities: Greek, Jewish, and Egyptian. By the time of Augustus, the city grid encompassed an area of 10 km, and the total population during the Roman principate was around 500,000–600,000, which would wax and wane in the course of the next four centuries under Roman rule. According to Philo of Alexandria, in the year 38 of the Common era, disturbances erupted between Jews and Greek citizens of Alexandria during a visit paid by King Agrippa I to Alexandria, principally over the respect paid by the Herodian nation to the Roman emperor, and which quickly escalated to open affronts and violence between the two ethnic groups and the desecration of Alexandrian synagogues. This event has been called the Alexandrian pogroms. The violence was quelled after Caligula intervened and had the Roman governor, Flaccus, removed from the city. In AD 115, large parts of Alexandria were destroyed during the Kitos War, which gave Hadrian and his architect, Decriannus, an opportunity to rebuild it. In 215, the emperor Caracalla visited the city and, because of some insulting satires that the inhabitants had directed at him, abruptly commanded his troops to put to death all youths capable of bearing arms. On 21 July 365, Alexandria was devastated by a tsunami (365 Crete earthquake), an event annually commemorated years later as a "day of horror". Islamic era In 619, Alexandria fell to the Sassanid Persians. Although the Byzantine emperor Heraclius recovered it in 629, in 641 the Arabs under the general 'Amr ibn al-'As invaded it during the Muslim conquest of Egypt, after a siege that lasted 14 months. The first Arab governor of Egypt recorded to have visited Alexandria was Utba ibn Abi Sufyan, who strengthened the Arab presence and built a governor's palace in the city in 664–665. After the Battle of Ridaniya in 1517, the city was conquered by the Ottoman Turks and remained under Ottoman rule until 1798. Alexandria lost much of its former importance to the Egyptian port city of Rosetta during the 9th to 18th centuries, and only regained its former prominence with the construction of the Mahmoudiyah Canal in 1807. Alexandria figured prominently in the military operations of Napoleon's expedition to Egypt in 1798. French troops stormed the city on 2 July 1798, and it remained in their hands until the arrival of a British expedition in 1801. The British won a considerable victory over the French at the Battle of Alexandria on 21 March 1801, following which they besieged the city, which fell to them on 2 September 1801. Muhammad Ali, the Ottoman governor of Egypt, began rebuilding and redevelopment around 1810, and by 1850, Alexandria had returned to something akin to its former glory. Egypt turned to Europe in their effort to modernize the country. Greeks, followed by other Europeans and others, began moving to the city. In the early 20th century, the city became a home for novelists and poets. In July 1882, the city came under bombardment from British naval forces and was occupied. In July 1954, the city was a target of an Israeli bombing campaign that later became known as the Lavon Affair. On 26 October 1954, Alexandria's Mansheya Square was the site of a failed assassination attempt on Gamal Abdel Nasser. Europeans began leaving Alexandria following the 1956 Suez Crisis that led to an outburst of Arab nationalism. The nationalization of property by Nasser, which reached its highest point in 1961, drove out nearly all the rest. Ibn Battuta in Alexandria In reference to Alexandria, Egypt, Ibn Battuta speaks of great saints that resided here. One of them being Imam Borhan Oddin El Aaraj. He was said to have the power of working miracles. He told Ibn Battuta that he should go find his three brothers, Farid Oddin, who lived in India, Rokn Oddin Ibn Zakarya, who lived in Sindia, and Borhan Oddin, who lived in China. Battuta then made it his purpose to find these people and give them his compliments. Sheikh Yakut was another great man. He was the disciple of Sheikh Abu Abbas El Mursi, who was the disciple of Abu El Hasan El Shadali, who is known to be a servant of God. Abu Abbas was the author of the Hizb El Bahr and was famous for piety and miracles. Abu Abd Allah El Murshidi was a great interpreting saint that lived secluded in the Minyat of Ibn Murshed. He lived alone but was visited daily by emirs, viziers, and crowds that wished to eat with him. The Sultan of Egypt (El Malik El Nasir) visited him, as well. Ibn Battuta left Alexandria with the intent of visiting him. Ibn Battuta also visited the Pharos lighthouse on 2 occasions; in 1326 he found it to be partly in ruins and in 1349 it had deteriorated further, making entrance to the edifice impossible. Timeline The most important battles and sieges of Alexandria include: Siege of Alexandria (47 BC), Julius Caesar's civil war Battle of Alexandria (30 BC), final war of the Roman Republic Siege of Alexandria (619), Byzantine-Persian Wars Siege of Alexandria (641), Rashidun conquest of Byzantine Egypt Alexandrian Crusade (1365), a crusade led by Peter de Lusignan of Cyprus which resulted in the defeat of the Mamluks and the sack of the city. Battle of Alexandria (1801), Napoleonic Wars Siege of Alexandria (1801), Napoleonic Wars Alexandria expedition (1807), Napoleonic Wars Bombardment of Alexandria (1882), followed by the British occupation of Egypt Ancient layout Greek Alexandria was divided into three regions: Brucheum Brucheum is the Royal or Greek quarter and forms the most magnificent portion of the city. In Roman times Brucheum was enlarged by the addition of an official quarter, making four regions in all. The city was laid out as a grid of parallel streets, each of which had an attendant subterranean canal. The Jewish quarter This quarter is the northeast portion of the city. Rhakotis Rhakotis (from Coptic Rakotə "Alexandria") is the old city that was absorbed into Alexandria. It was occupied chiefly by Egyptians. Two main streets, lined with colonnades and said to have been each about wide, intersected in the centre of the city, close to the point where the Sema (or Soma) of Alexander (his Mausoleum) rose. This point is very near the present mosque of Nebi Daniel; and the line of the great East–West "Canopic" street, only slightly diverged from that of the modern Boulevard de Rosette (now Sharia Fouad). Traces of its pavement and canal have been found near the Rosetta Gate, but remnants of streets and canals were exposed in 1899 by German excavators outside the east fortifications, which lie well within the area of the ancient city. Alexandria consisted originally of little more than the island of Pharos, which was joined to the mainland by a mole and called the Heptastadion ("seven stadia"—a stadium was a Greek unit of length measuring approximately ). The end of this abutted on the land at the head of the present Grand Square, where the "Moon Gate" rose. All that now lies between that point and the modern "Ras al-Tin" quarter is built on the silt which gradually widened and obliterated this mole. The Ras al-Tin quarter represents all that is left of the island of Pharos, the site of the actual lighthouse having been weathered away by the sea. On the east of the mole was the Great Harbour, now an open bay; on the west lay the port of Eunostos, with its inner basin Kibotos, now vastly enlarged to form the modern harbour. In Strabo's time (latter half of the 1st century BC), the principal buildings were as follows, enumerated as they were to be seen from a ship entering the Great Harbour. The Royal Palaces, filling the northeast angle of the town and occupying the promontory of Lochias, which shut in the Great Harbour on the east. Lochias (the modern Pharillon) has almost entirely disappeared into the sea, together with the palaces, the "Private Port," and the island of Antirrhodus. There has been a land subsidence here, as throughout the northeast coast of Africa. The Great Theater, on the modern Hospital Hill near the Ramleh station. This was used by Julius Caesar as a fortress, where he withstood a siege from the city mob after he took Egypt after the battle of Pharsalus The Poseidon, or Temple of the Sea God, close to the theater The Timonium built by Marc Antony The Emporium (Exchange) The Apostases (Magazines) The Navalia (Docks), lying west of the Timonium, along the seafront as far as the mole Behind the Emporium rose the Great Caesareum, by which stood the two great obelisks, which become known as "Cleopatra's Needles," and were transported to New York City and London. This temple became, in time, the Patriarchal Church, though some ancient remains of the temple have been discovered. The actual Caesareum, the parts not eroded by the waves, lies under the houses lining the new seawall. The Gymnasium and the Palaestra are both inland, near the Boulevard de Rosette in the eastern half of the town; sites unknown. The Temple of Saturn; site unknown. The Mausolea of Alexander (Soma) and the Ptolemies in one ring-fence, near the point of intersection of the two main streets. The Musaeum with its famous Library and theater in the same region; site unknown. The Serapeum of Alexandria, the most famous of all Alexandrian temples. Strabo tells us that this stood in the west of the city; and recent discoveries go far as to place it near "Pompey's Pillar," which was an independent monument erected to commemorate Diocletian's siege of the city. The names of a few other public buildings on the mainland are known, but there is little information as to their actual position. None, however, are as famous as the building that stood on the eastern point of Pharos island. There, The Great Lighthouse, one of the Seven Wonders of the World, reputed to be high, was situated. The first Ptolemy began the project, and the second Ptolemy (Ptolemy II Philadelphus) completed it, at a total cost of 800 talents. It took 12 years to complete and served as a prototype for all later lighthouses in the world. The light was produced by a furnace at the top and the tower was built mostly with solid blocks of limestone. The Pharos lighthouse was destroyed by an earthquake in the 14th century, making it the second longest surviving ancient wonder, after the Great Pyramid of Giza. A temple of Hephaestus also stood on Pharos at the head of the mole. In the 1st century, the population of Alexandria contained over 180,000 adult male citizens, according to a census dated from 32 CE, in addition to a large number of freedmen, women, children and slaves. Estimates of the total population range from 216,000 to 500,000, making it one of the largest cities ever built before the Industrial Revolution and the largest pre-industrial city that was not an imperial capital. Geography Alexandria is located in the country of Egypt, on the southern coast of the Mediterranean. It is in the Far West Nile delta area. Its an extremely densely populated city in its core areas belies its large administrative area. Notes:2020 CAPMAS projection based on 2017 revised census figures, may differ significantly from 2017 census preliminary tabulations. The 14 kisms were reported simply as Alexandria city by CAPMAS in 2006 but given explosive growth definitions, likely informal, may have change or may be set to change. Same area with 12 kisms existed in 1996. Kisms are considered 'fully urbanized' Climate Alexandria has a hot desert climate (Köppen climate classification: BWh), bordering on a hot steppe climate (Koppen climate classification: BSh). Like the rest of Egypt's northern coast, the prevailing north wind, blowing across the Mediterranean, gives the city a less severe climate than the desert hinterland. Rafah and Alexandria are the wettest places in Egypt; the other wettest places are Rosetta, Baltim, Kafr el-Dawwar, and Mersa Matruh. The city's climate is influenced by the Mediterranean Sea, moderating its temperatures, causing variable rainy winters and moderately hot and slightly prolonged summers that, at times, can be very humid; January and February are the coolest months, with daily maximum temperatures typically ranging from and minimum temperatures that could reach . Alexandria experiences violent storms, rain and sometimes sleet and hail during the cooler months; these events, combined with a poor drainage system, have been responsible for occasional flooding in the city in the past though they rarely occur anymore. July and August are the hottest and driest months of the year, with an average daily maximum temperature of . The average annual rainfall is around but has been as high as Port Said, Kosseir, Baltim, Damietta and Alexandria have the least temperature variation in Egypt. The highest recorded temperature was on 30 May 1961, and the coldest recorded temperature was on 31 January 1994. Cityscape Due to the constant presence of war in Alexandria in ancient times, very little of the ancient city has survived into the present day. Much of the royal and civic quarters sank beneath the harbour and the rest has been built over in modern times. Pompey's Pillar "Pompey's Pillar", a Roman triumphal column, is one of the best-known ancient monuments still standing in Alexandria today. It is located on Alexandria's ancient acropolis—a modest hill located adjacent to the city's Arab cemetery—and was originally part of a temple colonnade. Including its pedestal, it is 30 m (99 ft) high; the shaft is of polished red granite, in diameter at the base, tapering to at the top. The shaft is high, and made out of a single piece of granite. Its volume is and weight approximately 396 tons. Pompey's Pillar may have been erected using the same methods that were used to erect the ancient obelisks. The Romans had cranes but they were not strong enough to lift something this heavy. Roger Hopkins and Mark Lehrner conducted several obelisk erecting experiments including a successful attempt to erect a 25-ton obelisk in 1999. This followed two experiments to erect smaller obelisks and two failed attempts to erect a 25-ton obelisk. The structure was plundered and demolished in the 4th century when a bishop decreed that Paganism must be eradicated. "Pompey's Pillar" is a misnomer, as it has nothing to do with Pompey, having been erected in 293 for Diocletian, possibly in memory of the rebellion of Domitius Domitianus. Beneath the acropolis itself are the subterranean remains of the Serapeum, where the mysteries of the god Serapis were enacted, and whose carved wall niches are believed to have provided overflow storage space for the ancient Library. In more recent years, many ancient artifacts have been discovered from the surrounding sea, mostly pieces of old pottery. Catacombs of Kom El Shoqafa Alexandria's catacombs, known as Kom El Shoqafa, are a short distance southwest of the pillar, consist of a multi-level labyrinth, reached via a large spiral staircase, and featuring dozens of chambers adorned with sculpted pillars, statues, and other syncretic Romano-Egyptian religious symbols, burial niches, and sarcophagi, as well as a large Roman-style banquet room, where memorial meals were conducted by relatives of the deceased. The catacombs were long forgotten by the citizens until they were discovered by accident in 1900. Kom El Deka The most extensive ancient excavation currently being conducted in Alexandria is known as Kom El Deka. It has revealed the ancient city's well-preserved theater, and the remains of its Roman-era baths. Temple of Taposiris Magna The temple was built in the Ptolemy era and dedicated to Osiris, which finished the construction of Alexandria. It is located in Abusir, the western suburb of Alexandria in Borg el Arab city. Only the outer wall and the pylons remain from the temple. There is evidence to prove that sacred animals were worshiped there. Archaeologists found an animal necropolis near the temple. Remains of a Christian church show that the temple was used as a church in later centuries. Also found in the same area are remains of public baths built by the emperor Justinian, a seawall, quays and a bridge. Near the beach side of the area, there are the remains of a tower built by Ptolemy II Philadelphus. The tower was an exact scale replica of the destroyed Alexandrine Pharos Lighthouse. Citadel of Qaitbay Citadel of Qaitbay is a defensive fortress located on the Mediterranean sea coast. It was established in 1477 AD (882 AH) by the mamluk Sultan Al-Ashraf Sayf al-Din Qa'it Bay. The Citadel is located on the eastern side of the northern tip of Pharos Island at the mouth of the Eastern Harbour. It was erected on the exact site of the famous Lighthouse of Alexandria, which was one of the Seven Wonders of the Ancient World. It was built on an area of 17,550 square metres. Excavation Persistent efforts have been made to explore the antiquities of Alexandria. Encouragement and help have been given by the local Archaeological Society, and by many individuals, notably Greeks proud of a city which is one of the glories of their national history. Excavations were performed in the city by Greeks seeking the tomb of Alexander the Great without success. The past and present directors of the museum have been enabled from time to time to carry out systematic excavations whenever opportunity is offered; D. G. Hogarth made tentative researches on behalf of the Egypt Exploration Fund and the Society for the Promotion of Hellenic Studies in 1895; and a German expedition worked for two years (1898–1899). But two difficulties face the would-be excavator in Alexandria: lack of space for excavation and the underwater location of some areas of interest. Since the great and growing modern city stands immediately over the ancient one, it is almost impossible to find any considerable space in which to dig, except at enormous cost. Cleopatra VII's royal quarters were inundated by earthquakes and tsunami, leading to gradual subsidence in the 4th century AD. This underwater section, containing many of the most interesting sections of the Hellenistic city, including the palace quarter, was explored in 1992 and is still being extensively investigated by the French underwater archaeologist Franck Goddio and his team. It raised a noted head of Caesarion. These are being opened up to tourists, to some controversy. The spaces that are most open are the low grounds to northeast and southwest, where it is practically impossible to get below the Roman strata. The most important results were those achieved by Dr. G. Botti, late director of the museum, in the neighborhood of "Pompey's Pillar", where there is a good deal of open ground. Here, substructures of a large building or group of buildings have been exposed, which are perhaps part of the Serapeum. Nearby, immense catacombs and columbaria have been opened which may have been appendages of the temple. These contain one very remarkable vault with curious painted reliefs, now artificially lit and open to visitors. The objects found in these researches are in the museum, the most notable being a great basalt bull, probably once an object of cult in the Serapeum. Other catacombs and tombs have been opened in Kom El Shoqafa (Roman) and Ras El Tin (painted). The German excavation team found remains of a Ptolemaic colonnade and streets in the north-east of the city, but little else. Hogarth explored part of an immense brick structure under the mound of Kom El Deka, which may have been part of the Paneum, the Mausolea, or a Roman fortress. The making of the new foreshore led to the dredging up of remains of the Patriarchal Church; and the foundations of modern buildings are seldom laid without some objects of antiquity being discovered. Places of worship Islam The most famous mosque in Alexandria is Abu al-Abbas al-Mursi Mosque in Bahary. Other notable mosques in the city include Ali ibn Abi Talib mosque in Somouha, Bilal mosque, al-Gamaa al-Bahari in Mandara, Hatem mosque in Somouha, Hoda el-Islam mosque in Sidi Bishr, al-Mowasah mosque in Hadara, Sharq al-Madina mosque in Miami, al-Shohadaa mosque in Mostafa Kamel, Al Qa'ed Ibrahim Mosque, Yehia mosque in Zizinia, Sidi Gaber mosque in Sidi Gaber, Sidi B esher mosque, Rokay el-Islam mosque in Elessway, Elsadaka Mosque in Sidibesher Qebly, Elshatbi mosque and Sultan mosque. Alexandria is the base of the Salafi movements in Egypt. Al-Nour Party, which is based in the city and overwhelmingly won most of the Salafi votes in the 2011–12 parliamentary election, supports the president Abdel Fattah el-Sisi. Christianity Alexandria was once considered the third-most important see in Christianity, after Rome and Constantinople. Until 430, the Pope of Alexandria was second only to the bishop of Rome. The Church of Alexandria had jurisdiction over most of the continent of Africa. After the Council of Chalcedon in AD 451, the Alexandrian Church split between the Miaphysites and the Melkites. The Miaphysites went on to constitute what is known today as the Coptic Orthodox Church. The Melkites went on to constitute what is known today as the Greek Orthodox Church of Alexandria. In the 19th century, Catholic and Protestant missionaries converted some of the adherents of the Orthodox churches to their respective faiths. Today the Patriarchal seat of the Pope of the Coptic Orthodox Church is Saint Mark Cathedral (though in practice the Patriarch has long resided in Cairo). The most important Coptic Orthodox churches in Alexandria include Pope Cyril I Church in Cleopatra, Saint George's Church in Sporting, Saint Mark & Pope Peter I Church in Sidi Bishr, Saint Mary Church in Assafra, Saint Mary Church in Gianaclis, Saint Mina Church in Fleming, Saint Mina Church in Mandara and Saint Takla Haymanot's Church in Ibrahimeya. The most important Eastern Orthodox churches in Alexandria are Agioi Anárgyroi Church, Church of the Annunciation, Saint Anthony Church, Archangels Gabriel & Michael Church, Taxiarchon Church, Saint Catherine Church, Cathedral of the Dormition in Mansheya, Church of the Dormition, Prophet Elijah Church, Saint George Church, Saint Joseph Church in Fleming, Saint Joseph of Arimathea Church, Saint Mark & Saint Nektarios Chapel in Ramleh, Saint Nicholas Church, Saint Paraskevi Church, Saint Sava Cathedral in Ramleh, Saint Theodore Chapel and the Russian church of Saint Alexander Nevsky in Alexandria, which serves the Russian speaking community in the city. The Apostolic Vicariate of Alexandria in Egypt-Heliopolis-Port Said has jurisdiction over all Latin Catholics in Egypt. Member churches include Saint Catherine Church in Mansheya and Church of the Jesuits in Cleopatra. The city is also the nominal see of the Melkite Greek Catholic titular Patriarchate of Alexandria (generally vested in its leading Patriarch of Antioch) and the actual cathedral see of its Patriarchal territory of Egypt, Sudan and South Sudan, which uses the Byzantine Rite, and the nominal see of the Armenian Catholic Eparchy of Alexandria (for all Egypt and Sudan, whose actual cathedral is in Cairo), a suffragan of the Armenian Catholic Patriarch of Cilicia, using the Armenian Rite. The Saint Mark Church in Shatby, founded as part of Collège Saint Marc, is multi-denominational and holds liturgies according to Latin Catholic, Coptic Catholic and Coptic Orthodox rites. In antiquity Alexandria was a major centre of the cosmopolitan religious movement called Gnosticism (today mainly remembered as a Christian heresy). Judaism Alexandria's once-flourishing Jewish community declined rapidly following the 1948 Arab–Israeli War, after which negative reactions towards Zionism among Egyptians led to Jewish residents in the city, and elsewhere in Egypt, being perceived as Zionist collaborators. Most Jewish residents of Egypt fled to the newly established Israel, France, Brazil and other countries in the 1950s and 1960s. The community once numbered 50,000 but is now estimated at below 50. The most important synagogue in Alexandria is the Eliyahu Hanavi Synagogue. Education Colleges and universities Alexandria has a number of higher education institutions. Alexandria University is a public university that follows the Egyptian system of higher education. Many of its faculties are internationally renowned, most notably its Faculty of Medicine & Faculty of Engineering. In addition, the Egypt-Japan University of Science and Technology in New Borg El Arab city is a research university set up in collaboration between the Japanese and Egyptian governments in 2010. The Arab Academy for Science, Technology & Maritime Transport is a semi-private educational institution that offers courses for high school, undergraduate level, and postgraduate students. It is considered the most reputable university in Egypt after the AUC American University in Cairo because of its worldwide recognition from board of engineers at UK & ABET in US. Université Senghor is a private French university that focuses on the teaching of humanities, politics and international relations, which mainly recruits students from the African continent. Other institutions of higher education in Alexandria include Alexandria Institute of Technology (AIT) and Pharos University in Alexandria. Schools Alexandria has a long history of foreign educational institutions. The first foreign schools date to the early 19th century, when French missionaries began establishing French charitable schools to educate the Egyptians. Today, the most important French schools in Alexandria run by Catholic missionaries include Collège de la Mère de Dieu, Collège Notre Dame de Sion, Collège Saint Marc, Écoles des Soeurs Franciscaines (four different schools), École Girard, École Saint Gabriel, École Saint-Vincent de Paul, École Saint Joseph, École Sainte Catherine, and Institution Sainte Jeanne-Antide. As a reaction to the establishment of French religious institutions, a secular (laic) mission established Lycée el-Horreya, which initially followed a French system of education, but is currently a public school run by the Egyptian government. The only school in Alexandria that completely follows the French educational system is Lycée Français d'Alexandrie (École Champollion). It is usually frequented by the children of French expatriates and diplomats in Alexandria. The Italian school is the Istituto "Don Bosco". English schools in Alexandria are becoming the most popular. English-language schools in the city include: Riada American School, Riada Language School, Alexandria Language School, Future Language School, Future International Schools (Future IGCSE, Future American School and Future German school), Alexandria American School, British School of Alexandria, Egyptian American School, Pioneers Language School, Egyptian English Language School, Princesses Girls' School, Sidi Gaber Language School, Taymour English School, Sacred Heart Girls' School, Schutz American School, Victoria College, El Manar Language School for Girls (previously called Scottish School for Girls), Kawmeya Language School, El Nasr Boys' School (previously called British Boys' School), and El Nasr Girls' College (previously called English Girls' College). There are only two German schools in Alexandria which are Deutsche Schule der Borromärinnen (DSB of Saint Charles Borromé) and Neue Deutsche Schule Alexandria, which is run by Frau Sally Hammam. The Montessori educational system was first introduced in Alexandria in 2009 at Alexandria Montessori. The most notable public schools in Alexandria include El Abbassia High School and Gamal Abdel Nasser High School. Women Around the 1890s, twice the percentage of women in Alexandria knew how to read compared to the same percentage in Cairo. As a result, specialist women's publications like al-Fatāh by Hind Nawal, the country's first women's journal, appeared. Transport Airports The city's principal airport is currently Borg El Arab Airport, which is located about away from the city centre. From late 2011, El Nouzha Airport (Alexandria International Airport) was to be closed to commercial operations for two years as it underwent expansion, with all airlines operating out of Borg El Arab Airport from then onwards, where a brand new terminal was completed there in February 2010. In 2017, the government announced that Alexandria International Airport will shut down permanently and will no longer reopen. Port Alexandria has four ports; namely the Western Port also known as Alexandria Port, which is the main port of the country that handles about 60% of the country's exports and imports, Dekhela Port west of the Western Port, the Eastern Port which is a yachting harbour, and Abu Qir Port at the northern east of the governorate. It is a commercial port for general cargo and phosphates. Highways International Coastal Road (Mersa Matruh – Alexandria – Port Said) Cairo–Alexandria desert road (Alexandria – Cairo – , 6–8 lanes) Cairo-Alexandria Agriculture Road (Alexandria – Cairo) Mehwar El Ta'meer – (Alexandria – Borg El Arab) Rail Alexandria's intracity commuter rail system extends from Misr Station (Alexandria's primary intercity railway station) to Abu Qir, parallel to the tram line. The commuter line's locomotives operate on diesel, as opposed to the overhead-electric tram. Alexandria plays host to two intercity railway stations: the aforementioned Misr Station (in the older Manshia district in the western part of the city) and Sidi Gaber railway station (in the district of Sidi Gaber in the centre of the eastern expansion in which most Alexandrines reside), both of which also serve the commuter rail line. Intercity passenger service is operated by Egyptian National Railways. Trams An extensive tramway network was built in 1860 and is the oldest in Africa. The network begins at the El Raml district in the west and ends in the Victoria district in the east. Most of the vehicles are blue in colour. Some smaller yellow-coloured vehicles have further routes beyond the two main endpoints. The tram routes have one of four numbers: 1, 2, 5, and 6. All four start at El Raml, but only two (1 and 2) reach Victoria. There are two converging and diverging points. The first starts at Bolkly (Isis) and ends at San Stefano. The other begins at Sporting and ends at Mostafa Kamel. Route 5 starts at San Stefano and takes the inner route to Bolkly. Route 6 starts at Sidi Gaber El Sheikh in the outer route between Sporting and Mustafa Kamel. Route 1 takes the inner route between San Stefano and Bolkly and the outer route between Sporting and Mustafa Kamel. Route 2 takes the route opposite to Route 1 in both these areas. The tram fares used to be 50 piastres (0.50 pounds), and 100 piastres (1.00 pounds) for the middle car, but have been doubled sometime in 2019. Some trams (that date back the 30s) charge a pound. The tram is considered the cheapest method of public transport. A café operates in the second floor of the first car of tram 1 (a women-only car) which costs 5 L.E per person, also offering a WiFi service.

Taxis and minibuses Taxis in Alexandria sport a yellow-and-black livery and are widely available. While Egyptian law requires all cabs to carry meters, these generally do not work and fares must be negotiated with the driver on either departure or arrival. The minibus share taxi system, or mashrū' operates along well-known traffic arteries. The routes can be identified by both their endpoints and the route between them: Corniche routes: El Mandara – Bahari El Mandara – El Mansheya Asafra – Bahari Asafra – El Mansheya El Sa'aa – El Mansheya Abu Qir routes: El Mandara – El Mahata (lit. "the Station", i.e. Misr Railway Station) Abu Qir – El Mahata Victoria – El Mahata El Mandara – Victoria Interior routes: Cabo – Bahari El Mansheya – El Awayid El Mansheya – El Maw'af El Gedid (the New Bus Station) Hadara – El Mahata The route is generally written in Arabic on the side of the vehicle, although some drivers change their route without changing the paint. Some drivers also drive only a segment of a route rather than the whole path; such drivers generally stop at a point known as a major hub of the transportation system (for example, Victoria) to allow riders to transfer to another car or to another mode of transport. Fare is generally L.E. 3.00 to travel the whole route. Shorter trips may have a lower fare, depending on the driver and the length of the trip. Culture Libraries The Royal Library of Alexandria, in Alexandria, Egypt, was once the largest library in the world. It is generally thought to have been founded at the beginning of the 3rd century BC, during the reign of Ptolemy II of Egypt. It was likely created after his father had built what would become the first part of the library complex, the temple of the Muses—the Museion, Greek Μουσείον (from which the Modern English word museum is derived). It has been reasonably established that the library, or parts of the collection, were destroyed by fire on a number of occasions (library fires were common and replacement of handwritten manuscripts was very difficult, expensive, and time-consuming). To this day the details of the destruction (or destructions) remain a lively source of controversy. The Bibliotheca Alexandrina was inaugurated in 2002, near the site of the old Library. Museums The Alexandria National Museum was inaugurated 31 December 2003. It is located in a restored Italian style palace in Tariq El Horreya Street (formerly Rue Fouad), near the centre of the city. It contains about 1,800 artifacts that narrate the story of Alexandria and Egypt. Most of these pieces came from other Egyptian museums. The museum is housed in the old Al-Saad Bassili Pasha Palace, who was one of the wealthiest wood merchants in Alexandria. Construction on the site was first undertaken in 1926. Cavafy Museum The Graeco-Roman Museum – its Director from 2004 to 2010 was archaeologist Mervat Seif el-Din The Museum of Fine Arts The Royal Jewelry Museum Theaters Alexandria Opera House, where classical music, Arabic music, ballet, and opera are performed and bearm basha theatre in elshatby. Architecture Throughout Alexandria, there is art that resembles some of the oldest architectural styles of the Hellenic city, and its ancient decorations, especially in the Bibliotheca Alexandrina, is based on reviving the ancient Library of Alexandria. The Kom el shoqafa Catacombs are considered one of the Seven Wonders of the Middle Ages and date back to the 2nd century. The remnants of Pompey's Pillar still remain today. This single pillar represents the elaborate temple which once stood in Alexandria. It remains at the site of the Serapeum, Alexandria's acropolis. The Serapeum, which stood for ancient tradition, conflicted with the rise of Christianity. It is a large tourist destination, today. the Roman Amphitheatre of Alexandria is another popular destination. Here, there remains a stage with around seven hundred to eight hundred seats. They also have numerous galleries of statues and details leftover form this time. Alexandria's tourism office announced plans to reserve some beaches for tourists in July 2018. Sports The main sport that interests Alexandrians is football, as is the case in the rest of Egypt and Africa. Alexandria Stadium is a multi-purpose stadium in Alexandria, Egypt. It is currently used mostly for football matches, and was used for the 2006 African Cup of Nations. The stadium is the oldest stadium in Egypt, being built in 1929. The stadium holds 20,000 people. Alexandria was one of three cities that participated in hosting the African Cup of Nations in January 2006, which Egypt won. Sea sports such as surfing, jet-skiing and water polo are practiced on a lower scale. The Skateboarding culture in Egypt started in this city. The city is also home to the Alexandria Sporting Club, which is especially known for its basketball team, which traditionally provides the country's national team with key players. The city hosted the AfroBasket, the continent's most prestigious basketball tournament, on four occasions (1970, 1975, 1983, 2003). Alexandria has four stadiums: Alexandria Stadium Borg El Arab Stadium El Krom Stadium Harras El Hodoud Stadium Other less popular sports like tennis and squash are usually played in private social and sports clubs, like: Alexandria Sporting Club – in "Sporting" Smouha Sporting Club – in "Smouha" Al Ittihad Alexandria Club Olympic Club Haras El Hodoud SC Club Koroum Club Lagoon Resort Courts Alexandria Country club Alexandria is known as the yearly starting point of Cross Egypt Challenge and a huge celebration is conducted the night before the rally starts after all the international participants arrive to the city. Cross Egypt Challenge is an international cross-country motorcycle and scooter rally conducted throughout the most difficult tracks and roads of Egypt.

Alexandria, Louisiana

Alexandria is the ninth-largest city in the state of Louisiana and is the parish seat of Rapides Parish, Louisiana, United States. It lies on the south bank of the Red River in almost the exact geographic center of the state. It is the principal city of the Alexandria metropolitan area (population 153,922) which encompasses all of Rapides and Grant parishes. Its neighboring city is Pineville. In 2010, the population was 47,723, an increase of 3 percent from the 2000 census. History Located along the Red River, the city of Alexandria was originally home to a community which supported activities of the adjacent French trader outpost of Post du Rapides. The area developed as an assemblage of traders, Caddo people, and merchants in the agricultural lands bordering the mostly unsettled areas to the north and providing a link from the south to the El Camino Real and then larger settlement of Natchitoches, the oldest permanent settlement in the Louisiana Purchase. Alexander Fulton, a businessman from Washington County, near Pittsburgh, Pennsylvania, received a land grant from Spain in 1762, and the first organized settlement was made at some point in the 1780s. In 1805, Fulton and business partner Thomas Harris Maddox laid out the town plan and named the town in Fulton's honor. The earliest deed that survives for an Alexandria resident is from June 24, 1801, when a William Cochren, who identifies himself as "Slave master of the Southern Americas", sold a tract of land across the Red River to a William Murrey. That same year, Fulton was appointed coroner in Rapides Parish by territorial Governor William C.C. Claiborne. Alexandria was incorporated as a town in 1818 and received a city charter in 1832. World War II In 1942, Alexandria was the site of the Lee Street Riot, one of the bloodiest domestic military incidents in American history, when a White military police officer engaged a Black soldier from Camp Claiborne and caused a race riot (arguably a White massacre), resulting in the deaths of 20 to 300 Black soldiers and civilians. An official count was never formulated, and there was debate as recently as 2020 concerning whether a mass grave was utilized. Geography and climate Alexandria is located at and has an elevation of . According to the United States Census Bureau, the city has a total area of , of which 26.4 square miles (68.4 km2) is land and 0.6 square mile (1.5 km2) (2.15%) is water. Alexandria is on a level plain in the center of the Louisiana Longleaf Pine forests, in which pine is interspersed with various hardwoods. A number of small bayous, such as Bayou Rapides, Bayou Robert, and Hynson Bayou, meander throughout the city. In the immediate vicinity of the city, cotton, sugar, alfalfa, and garden vegetables are cultivated. The climate is humid subtropical with some continental influence in the winter. Summers are consistently hot and humid, whereas winters are mild, with occasional cold snaps. On average, the first freeze occurs in early to mid November and the last freeze occurs in early to mid March. The area receives plentiful rainfall year-round, with thunderstorms possible throughout the year. Some storms can be severe, especially during the spring months. According to 'Cities Ranked and Rated' (Bert Sperling and Peter Sander), Alexandria reports an average of 69 days per year with thunder reported, which is nearly double the national average. Snowfall is rare, with measurable snow having occurred 27 times since 1895. The heaviest snowfall event took place February 12–13, 1960, when 9.1" of snow fell. Tropical storms and hurricanes affect Alexandria from time to time, but rarely cause severe damage, unlike areas closer to the coast. In September 2005, Hurricane Rita moved inland and affected Alexandria and surrounding areas, causing widespread power outages and damaging the roofs of some structures. The most recent hurricane, Gustav in 2008, caused widespread flooding, knocked over trees and power lines leading to power outages, and damaged structures. Some low-lying Alexandria neighborhoods had substantial flooding from Gustav, leaving several feet of water in houses. Demographics 2020 census As of the 2020 United States census, there were 45,275 people, 17,920 households, and 10,933 families residing in the city. 2010 census As of the census of 2010, there were 47,723 people, 17,816 households, and 11,722 families residing in the city. The population density was 1,754.6/sq mi (677.5/km2). There were 19,806 housing units at an average density of 749.9 per square mile (289.6/km2). The racial makeup of the city was 38.32% White, 57.25% Black, 1.25% Native American, 1.85% Asian, 0.14% Pacific Islander, 1.03% from other races, and 1.09% from two or more races. 6.98% of the population were Hispanic or Latino of any race. There were 17,816 households, out of which 31.9% had children under the age of 18 living with them, 38.5% were married couples living together, 23.2% had a female householder with no husband present, and 34.2% were non-families. 30.4% of all households were made up of individuals, and 12.1% had someone living alone who was 65 years of age or older. The average household size was 2.50 and the average family size was 3.13. In the city, the population was spread out, with 28.1% under the age of 18, 9.2% from 18 to 24, 26.2% from 25 to 44, 21.4% from 45 to 64, and 15.1% who were 65 years of age or older.

Religion Like many other southern cities, the largest single church denomination in the Alexandria area is Southern Baptist. Large congregations include the Emmanuel Baptist Church and Calvary Baptist Church. Alexandria is the headquarters of the Louisiana Baptist Convention. Alexandria also has a significant number of Methodists, Presbyterians, Episcopalians, and Pentecostals. A significant Catholic population is also present, a result of the large Catholic Acadian French population which resides in and around Alexandria, many from neighboring Avoyelles Parish. Alexandria is the headquarters for the Diocese of Alexandria. Alexandria has a small, though active Jewish community which dates back to the mid-19th century. Jews have held positions in local government, civic organizations, education, and medicine. At one time, many large businesses in the downtown were Jewish-owned. The Jewish community in Alexandria maintains two synagogues, which are approximately two blocks apart: Congregation Gemiluth Chassodim (Reform) and B'nai Israel Traditional Synagogue (Conservative). Annual cultural events and festivals Mardi Gras Though Alexandria is north of the Cajun cultural area, the city recognizes Mardi Gras as an official holiday. The annual Mardi Gras Krewes Parade – occurring on the Sunday before Mardi Gras – on Texas Avenue is a major cultural festivity in the area. It is featured as a family-oriented event, and parade goers can enjoy over 20 New Orleans style floats, high school and college marching bands, as well as appearances by local celebrities. In addition to the main Sunday parade, the College Cheerleaders & Classic Cars Parade, which was established in 2008, takes place downtown on the Friday before Mardi Gras, the Children's Parade takes place downtown on the Saturday before Mardi Gras, and the Krewe of Provine Parade is held on Fat Tuesday, processing along Coliseum Boulevard. All the events are organized by the Alexandria Mardi Gras Association (AMGA). The Krewe Parade can attract from 120,000 to 150,000; the Children's parade, up to 40,000 to 50,000, and the College Cheerleaders & Classic Cars, about 5,000 to 15,000 people. Alex River Fête An annual three-day festival is held in downtown Alexandria around late April and early May. The festival, established in 2013, was created around a former successful stand-alone event, the Louisiana Dragon Boat Races. It features the race and other former stand-alone events such as Dinner on the Bricks and the ArtWalk (now Art Fête) along with various booth venues, food, and live music, as well as the Kids Fête and Classic Car Fête. Alex Winter Fête An annual three day festival held in downtown Alexandria around early December. Launched in 2015, the festival first year drew about double the anticipated crowd of 15,000. The festival, like the Alex River Fête, feature booth venues, food, and live music but also features an ice rink. In January 2017, the Alex Winter Fête was voted Festival of the Year by the Louisiana Travel Promotion Association. Former events Cenlabration Begun in the late 1980s, Cenlabration was one of the largest festivals in Central Louisiana (Cenla). The name comes from Central Louisiana ("LA") Celebration, and reflects local culture and heritage, as well as serving as a means of celebrating Labor Day as the end of summer. As many as three stages support a particular type of music, including Cajun and zydeco, blues and jazz, and Country music. In addition there are arts and crafts booths for local artists to sell their wares. In the Children's Village, children can participate in arts and crafts, listen to storytellers, play games with clowns, or watch a play. The festival has plenty of carnival rides available as well. Cenlabration ends with a large fireworks display. The festival ran for 20 years until cancellation due to finances. The city ended its annual support of $40,000 because of budget constraints. RiverFest In 2002, representatives of local government, businesses, organizations, and community formed the nonprofit organization River Cities Cultural Alliance, Inc. to promote tourism and the arts through a celebration of Central Louisiana's diverse cultural heritage. The nonprofit served to organize and put on RiverFest: Heritage and Arts on the Red. More than ten thousand festival-goers attending the event. RiverFest was held in downtown Alexandria and on the Alexandria and Pineville levees. The festival features the work of visual artists from across the South, food booths exemplifying southern cuisine, a variety of children's activities, three outdoor stages with a wide range of music, dance, and theatrical performances, and a literary component with readings and panel discussions by Louisiana authors and scholars. RiverFest was canceled in 2007. Que'in on the Red An annual barbecue festival launched in 2006, the festival was held on the levee near downtown Alexandria and was well known for its big-name entertainment. The event was cancelled in 2012 due to its high cost and the city deciding against continued support of $100,000 annually. Museums The Alexandria Museum of Art was founded in 1977 and occupies an historic Rapides Bank Building on the banks of the Red River. The building was built c. 1898 and is listed on the National Register of Historic Places. The museum opened to the public in March 1998. In 1998, the Alexandria Museum of Art expanded and constructed its grand foyer and offices as an annex to the Rapides Bank Building. In 1999, the Alexandria Museum of Art was honored as an Outstanding Arts Organization in the Louisiana Governor's Arts Awards. In 2007, the Alexandria Museum of Art entered into a collaborative endeavor agreement with Louisiana State University of Alexandria (LSUA). The Alexandria Museum of Art now also serves as a downtown campus for LSUA classes, and is host to multidisciplinary community events, including concerts and recitals, lectures, yoga classes, Second Saturday Markets, and Museum Afterhours. The Louisiana History Museum is located downtown on the bottom floor of the former library. A small facility, it showcases the history of all Louisiana, with emphasis on the central portion of the state, Rapides Parish, and Alexandria. Major exhibit areas concern Native Americans, Louisiana geography, politics, health care, farming, and the impact of war. The T.R.E.E. House Children's Museum and Arna Bontemps African American Museum are located within the Cultural Arts District. The Kent Plantation House in Alexandria, completed by 1800, was located on a Spanish land grant. It is the oldest standing structure in Central Louisiana, one of only two buildings in the city to survive the burning of 1864 by Union troops fleeing after having been defeated at the Battle of Mansfield in DeSoto Parish. The house has been moved from its original location but is still located on part of the first land grant. It is open for tours daily except Sundays at 9, 10, and 11 a.m. and 1, 2, and 3 p.m. The tour is led by costumed docents and includes the house furnished in period pieces, some belonging to the original family, and all nine outbuildings, including an 1840-50s sugar mill, blacksmith shop, barn, two slave cabins, open-hearth kitchen, and milk house. Performing arts The performing arts are centered in the Alexandria Cultural Arts District in the downtown. Located within a few blocks of each other are three performance venues: Coughlin-Saunders Performing Arts Center, the Hearn Stage, and the Riverfront Amphitheater. The Coughlin-Saunders Performing Arts Center is the home of the Rapides Symphony Orchestra, which has performed in Alexandria since 1968. The center hosts the Performing Arts Series of the Arts Council of Central Louisiana, the Red River Chorale (an auditioned community chorus), and presentations of numerous local theater groups. The land for the center was donated by The Alexandria Town Talk newspaper, owned by the Gannett Company of McLean, Virginia. Businesswoman Jacqueline Seagall Caplan (1935–2016) was the president of the Arts Council of Central Louisiana and the chairman of the group's executive committee when the Coughlin-Saunders Performing Arts Center opened in 2004. She predicted that Coughlin-Saunders would in time "provide a place people can point to and say it's theirs. ... [Until now], we've never had a performing arts center where every type of performing art can come." The Hearn Stage is a black box theater for smaller productions. The Arts Council provides day-to-day management of both the Coughlin-Saunders Center and the Hearn Stage. The Riverfront Amphitheater hosts each April a "Jazz on the River" music festival, sponsored by the Arna Bontemps African American Museum. The Rapides Symphony holds an annual fall Pops concert in the amphitheater. In recent years, the amphitheater has welcomed musical guests in conjunction with the springtime Dragonboat Races sponsored by the Alexandria Museum of Art. The spring and fall seasons also feature Downtown Rocks, a free outdoor concert series in nearby Fulton Park. Sports Alexandria was home to the Alexandria Aces, a summer college league baseball team. The Aces were champions in various leagues in 1997, 1998, 2006, and 2007. They played their home games at Bringhurst Field. Unfortunately, due to lack of repairs on the stadium, combined with the aging of it caused interest in the team to unfortunately drop, with much of the wooden stands being barricaded. The remaining games of the 2013 season were canceled in mid-July because of low attendance, which averaged fewer than two hundred per game. The stadium's office and clubhouse were destroyed by a fire in 2014 and were subsequently torn down. In 2017, it was decided that the stadium would become a green space, open to the public and welcome news to those concerned about the building's future. The scoreboard and outfield walls have been removed, but most of the stadium is still intact. In 1974, a Little League team from Alexandria won the Louisiana state championship. Alexandria had a minor league ice hockey team, the Alexandria Warthogs. They played their home games at the Rapides Parish Coliseum. A professional indoor football team, the Louisiana Rangers, played their home games at the Rapides Parish Coliseum. They played in the Central District of the Southern American Football League, and the Southern Conference of the National Indoor Football League (NIFL). The team was owned by a Lafayette business group before moving in 2003 to Beaumont, Texas. Alexandria is also home to the U-14 Crossroads Pride soccer team. They won the 2012 Louisiana Soccer Association State Cup. The Pool Boys FC soccer team, a member of the Gulf Coast Premier League, plays at Johnny Downs Sports Complex. Nearby is Bringhurst Golf Course, popularly known as "the nation's oldest par-three course." A full-scale renovation was completed in mid-2010.

The newspaper was owned by the family of the late Jane Wilson Smith and Joe D. Smith, Jr., until March 1996, when it was sold to Central Newspapers. In August 2000, the Gannett Company acquired the Central Newspapers properties, including The Town Talk. The name of the paper on its inaugural issue was the Alexandria Daily Town Talk. Although it has since been shorted to the current The Town Talk, it is still frequently referred to by long-time residents as the Daily Town Talk.

The zoo is accredited by the Association of Zoos and Aquariums (AZA) and takes part in about 20 Species Survival Plans (SSP) as part of its conservation efforts. Cotile Lake Recreation Area Cotile Lake is a man-made impoundment located in the uplands approximately west-northwest of Alexandria, Louisiana. The lake is approximately in size and was completed in October 1965. The Louisiana Wild Life and Fisheries Commission stocked this impoundment with the proper species and number of game fish in 1965–66 shortly after its completion date. The recreational facilities include a large area cleared and zoned for swimming with complete bath house facilities nearby. There is a water skiing area that is cleared and snagged for safety of the skiers. The picnic and camping areas are modern and complete. There is also space available for campers. Indian Creek Lake and Recreation Area Encompasses a lake, of developed recreation facilities and a primitive camping area all within the Alexander State Forest. The lake, located in central Louisiana, was constructed as a joint venture of the Louisiana Forestry Commission, the Rapides Parish Police Jury, and the Lower West Red River Soil and Water Conservation District as a reservoir for agricultural irrigation in times of need and for recreation purposes. The recreation area camping area contains 109 campsites with conventional full utility hookups, 3 beaches for swimming, bath houses, a boat launch, and 75 picnic sites. A covered pavilion within the developed area provides for groups up to 100 people. The recreation area is open year-round and operates on user fees. Kisatchie National Forest Alexandria sits in the middle of the Kisatchie National Forest. Ranger districts are north, northwest, west and southwest of the city. An abundance of large timberlands and forest nurseries, as well as lake and recreation areas, are within a short driving distance.

The 199th BSB is the logistical component of the 256th Infantry Brigade that served in Operation Iraqi Freedom from October 2004 until September 2005. The 199th BSB provides supply and transportation (Company A), medical (Company C) and maintenance (Company B) support and services that keep the 256th Brigade operational. The battalion also has units located in Jonesboro, Winnfield, Colfax, and St. Martinville, Louisiana. England Air Force Base Alexandria served as the home of England Air Force Base from its origins as an emergency airstrip for Esler Regional Airport until its closure. England AFB was officially closed on December 15, 1992, pursuant to the Defense Base Closure and Realignment Act (Public Law 101–510) and recommendations of the Defense Secretary's Commission on Base Realignment and Closure. The base now serves as Alexandria International Airport (see below). Economy According to Census ACS 1-year survey for 2016, the per capita income of Alexandria was $23,962. This is $1,702 lower than the Louisiana average for per capita income in the same period. That figure is at $31,128 nationally. The Alexandria workforce consists of about 55,000 residents. Union Tank Car Company has recently located a plant northwest of Alexandria near the airport creating hundreds of jobs. Expansions at the Procter & Gamble plant and the construction of a PlastiPak plant in nearby Pineville have also created a number of new jobs for the area. Sundrop Fuels Inc., a Colorado-based biofuels start-up, plans to construct an over 1,200 acre plant just southwest of Alexandria in Rapides Station area. The facility will serve as the headquarters for the company because aside from the plant itself, Sundrop has also bought Cowboy Town, an abandon entertainment venue that sits inside the surrounding land that was purchased, to house their offices and their maintenance and fabrication operations. In 2007, Inc. Magazine rated Alexandria as the 77th best place in which to conduct business out of the 393 U.S. cities ranked, a significant increase from its ranking as No. 276 in 2006. Among other Louisiana cities, Alexandria ranked second, following only Baton Rouge, which ranked 59th nationally. Healthcare Alexandria is home to two major hospitals: Rapides Regional Medical Center, a former Baptist hospital is located downtown. Christus St. Frances Cabrini Hospital was opened in 1950 and is located at the corner of Masonic Drive and Texas Avenue. Both hospitals have undergone expansion. Additionally, located just across the Red River in Pineville, the Veteran's Affairs Medical Center at Alexandria serves central Louisiana and surrounding areas. Meanwhile, in 2013, the state allocated $15 million to move the medical services long provided at no or minimal charge at the Huey P. Long Medical Center in Pineville to the former hospital at England Park at the site of the closed England Air Force Base. Port of Alexandria In the early 19th century, the Port of Alexandria brought goods to the area and shipped cotton and other local products to the rest of the country. A ferry connected the cities of Alexandria and Pineville until a bridge was built across the Red in 1900. Today, Port facilities include: a 40-ton crane for off-loading, a warehouse, 13,600-ton bulk fertilizer warehouse, a 3,400-ton bulk fertilizer dome structure and a 5,000-ton dome which was added in January 2005. The petroleum off-loading facility includes two tanks, one tank capable of handling two barges and five truck off-loading simultaneously. There is also a general cargo dock with access to rail and a hopper barge unloading dock with conveyor system. Today's modern facilities and the Port's central location with its connection to the Mississippi River provide excellent opportunities for importers and exporters. Alexandria International Airport Alexandria International Airport (AEX) is a regional airport, providing flights to Atlanta, Dallas/Ft. Worth, and Houston. In 2006 a new-state-of-the-art passenger terminal was dedicated. Alexandria is served by American, United, and Delta. Current military use Formerly known as England AFB until 1992, Alexandria International Airport additionally has numerous international charter airlines using the airport in the transport of military personnel attached to the United States Army base at Fort Polk. A new military personnel terminal opened in 2007. Government and politics Local government History Following the Civil War, all public records in Alexandria had been destroyed. On September 29, 1868, the city was granted a new charter with a government consisting of a Mayor, Treasurer, and Justice of the Peace. Nine aldermen represented the four wards of the city – two from each ward and one elected at-large. In 1912, the Lawrason Act established Alexandria municipal government in a strong mayor format, where the mayor was also the Commissioner of Public Health and Safety (Police, Fire, Sanitation). There were separate Commissioners of Streets and Parks and Finance and Utilities, elected citywide. Those positions were discontinued in 1977. Today Alexandria has a mayoral-council system of government. The Mayor serves as the executive branch of the local government. The current Mayor – Jacques Roy – was elected to office in November 2006, succeeding long-time mayor Edward Gordon "Ned" Randolph, Jr. Randolph had succeeded John K. Snyder. The City Council serves as the legislative branch. The five districts of the city are represented on the council; in addition there are two council members elected to serve as at-large representatives of the city. The Alexandria Court has a limited jurisdiction, consisting of the citizens of Wards 1, 2 and 8 in Rapides Parish. Within those boundaries the court has the power to hear and decide both criminal and civil cases, rule in civil cases and hand down judgment for punishment in criminal cases. Area politics Overall, the people of the Alexandria area tend to be conservative. Even though the majority typically elects Republicans in national elections, they vote for Democrats in local elections, many of which are not contested by the GOP. United States Congressional district From 1913 to 1993, Alexandria served as the seat of Louisiana's Eighth Congressional district. A Democratic seat, it was held by the Long family for nearly half of its existence, from 1953 to 1987, broken only by the two terms of Harold B. McSween and three terms of Republican Clyde Holloway of Forest Hill. The seat was removed after the 1990 census indicated Louisiana no longer had the population to support it. The district was split among the Fourth, Fifth and Sixth Congressional districts. Alexandria is now in the Fifth district and was represented from 2003 to 2013 by Rodney Alexander, a Democrat-turned-Republican. From November 2013 to January 2015 the representative is Vance McAllister of Ouachita Parish. Education Colleges and universities Situated south of the city, Louisiana State University at Alexandria (or LSUA) is a regional campus of the state's flagship university system, Louisiana State University. From its establishment in 1959, the campus offered only two-year degrees; students seeking baccalaureate degrees had to commute or move to the main campus in Baton Rouge in order to gain a four-year degree. After 1976, students could either commute or telecommute in order to attend upper-level courses, including graduate classes. In 2002, following approval by the Louisiana State University Board of Supervisors and the Louisiana Board of Regents the Louisiana Legislature passed legislation allowing LSUA to offer baccalaureate degrees. A four-year degree is also attainable through Southern Baptist-affiliated Louisiana Christian University in Pineville, founded in 1906. Alexandria also has one of the Region 6 Louisiana Technical College campuses. Primary and secondary schools Rapides Parish School Board operates public schools. Alexandria has three public high schools: Bolton High School, Alexandria Senior High School, and Peabody Magnet High School. In addition, there are two private high schools: the Roman Catholic Holy Savior Menard Central High School, and Grace Christian. Transportation Roads Alexandria serves as the crossroads of Louisiana. To reach either Shreveport or Monroe from the southern portion of the state, the easiest method of travel takes the driver through Alexandria. Likewise, if a visitor is to head from the northern portion of the state to the Cajun portions of the state (Lake Charles and Lafayette), or the greater metropolitan areas of either Baton Rouge or New Orleans, the easiest method of travel involves driving down Interstate 49 through Alexandria. In addition to I-49, travelers can follow Louisiana 1 up to Alexandria from Baton Rouge and points south. Also, Highway 167 could be taken from Opelousas north to Ruston, crossing through Alexandria at one of the few bridges over the Red River in central Louisiana. Highways 165 and 71 also link Alexandria and points south with the northern and southern portions of the state via the Curtis-Coleman bridge. There are possible plans for a 50-mile, 4 lane beltway to encircle Alexandria and Pineville. As of now, it is only in the planning stages of development. Bridges Three road bridges cross the Red River in the Alexandria area. They are: The Purple Heart Memorial Bridge. Part of the Alexandria-Pineville Expressway (also referred to as the Cottingham Expressway), it connects Interstate 49 to Highway 167 by crossing the Red River from downtown Alexandria to Pineville. It replaced the Fulton Street Bridge and has six lanes of traffic. Designed by the Louisiana Department of Transportation and Development (LADOTD), the bridge cost $15.9 million in federal and state funds. The northbound portion was completed in 1995, the southbound in 1998. The U.S. 165 Business Bridge (alternatively, the Gillis Long Bridge, the Red River Bridge or the Jackson Street Bridge) connecting downtown Pineville with the business district in Alexandria. It is a two-lane vertical-lift bridge with a sidewalk/bikepath on either side. The bridge is named after U.S. Representative Gillis Long, who represented Louisiana's Eighth Congressional District. It was built in 1985 to replace the Murray Street Bridge. The Oscar K. Allen Bridge connecting Highway 165/71 on both sides of the Red River. It is a two-lane K-truss type bridge, named after Governor Oscar K. Allen. It was built in 1936 to connect Alexandria to the (former) Fort Buhlow. A new four-lane (two lanes in each direction) bridge is being built beside the aging OK Allen Bridge (appropriately named the Fort Buhlow Bridge) and should be open in mid-2013. At that time US 165 will be completely four-laned for most of its traverse of Louisiana. Former bridges include: The Murray Street Bridge. One of the first bridges in Alexandria. A two-lane steel truss swing bridge, it decayed over time, finally being demolished in 1983. The approach on the Alexandria side was turned into a river overlook as part of the Alexandria Levee Park. The Fulton Street Bridge. Named after Fulton Street which it connected with Highway 167. Technically part of the Alexandria-Pineville Expressway, it was a four-lane steel vertical-lift bridge. It was demolished in 1994 to make way for the Purple Heart Memorial Bridge. There are two railroad bridges over the Red River in Alexandria. One is located near the Buhlow area north of the OK Allen bridge. The other is south of the Purple Heart Memorial Bridge. Mass transit Regional mass transit is handled by ATRANS (Alexandria Transportation Authority). For those leaving or arriving at the city by bus, Greyhound Lines has a terminal downtown. Airports Alexandria is served by the Alexandria International Airport and the Esler Regional Airport in Pineville. Rail Alexandria does not have Amtrak service, nor a commuter rail system. The Kansas City Southern (Southern Belle) and the Missouri Pacific (since absorbed by Union Pacific) (Louisiana Eagle and Louisiana Daylight) operated train stations in the area in the early part of the 20th century but passenger services ended in the 1960s and the stations have closed.

Alexandria Troas

Alexandria Troas ("Alexandria of the Troad"; ; ) is the site of an ancient Greek city situated on the Aegean Sea near the northern tip of Turkey's western coast, the area known historically as Troad. a little south of Tenedos (modern Bozcaada). It is located southeast of modern Dalyan, a village in the Ezine district of Çanakkale Province. The site sprawls over an estimated ; among the few structures remaining today are a ruined bath, an odeon, a theatre, gymnasium complex and a recently uncovered stadion. The circuit of the old walls can still be traced. History Hellenistic According to Strabo, this site was first called Sigeia (Σιγία); around 306 BC Antigonus refounded the city as the much-expanded Antigonia Troas by settling the people of five other towns in Sigeia, including the once influential city of Neandreia. It did not receive its name until its name was changed by Lysimachus to Alexandria Troas, in 301 BC, in memory of Alexander III of Macedon (Pliny merely states, in his view, that the name changed from Antigonia to Alexandria). However, Pliny's view is not correct, because the city continued being called Alexandria Troas, and so is also stated in the 4th-5th c. AD Tabula Peutingeriana. As the chief port of north-west Asia Minor, the place prospered greatly in Roman times, becoming a "free and autonomous city" as early as 188 BC, and the existing remains sufficiently attest its former importance. In its heyday the city may have had a population of about 100,000. Strabo mentions that a Roman colony was created at the location in the reign of Augustus, named Colonia Alexandria Augusta Troas (called simply Troas during this period). Augustus, Hadrian and the rich grammarian Herodes Atticus contributed greatly to its embellishment; the aqueduct still preserved is due to the latter. Constantine considered making Troas the capital of the Roman Empire. Roman In Roman times, it was a significant port for travelling between Anatolia and Europe. According to the account in the Acts of the Apostles, Paul of Tarsus sailed for Europe for the first time from Alexandria Troas and returned there from Europe (it was there that the episode of the raising of Eutychus is said to have occurred). Ignatius of Antioch also paused at this city before continuing to his martyrdom at Rome. Byzantine Several of its later bishops are known: Marinus in 325; Niconius in 344; Sylvanus at the beginning of the 5th century; Pionius in 451; Leo in 787; Peter, friend of the Patriarch Ignatius, and adversary to Michael, in the ninth century. In the 10th century Troas is given as a suffragan of Cyzicus and distinct from the famous Troy (Heinrich Gelzer, Ungedruckte ... Texte der Notitiae episcopatuum, 552; Georgii Cyprii descriptio orbis romani, 64); it is not known when the city was destroyed and the diocese disappeared. The bishopric remains a titular see of the Catholic Church under the name Troas, vacant since 1971.<ref>Annuario Pontificio 2013 (Libreria Editrice Vaticana 2013 ), p. 997</ref> Troas is also a titular see of the Eastern Orthodox Church under the Ecumenical Patriarchate. Bishop Savas (Zembillas) of Troas served as hierarch from 2002 to 2011, and then became Metropolitan Savas (Zembillas) of Pittsburgh in the Greek Orthodox Archdiocese of America. Ottoman Karasid Turkomans settled in the area of the Troad in the 14th century. Their beylik was conquered by the Ottomans in 1336. The ruins of Alexandria Troas came to be known among the Turks as Eski Stambul, the "Old City". The site's stones were much plundered for building material (for example Mehmed IV took columns to adorn his Yeni Valide Mosque in Istanbul). As of the mid-18th century the site served as "a lurking place for bandetti". Modern By 1911, the site had been overgrown with Vallonea oaks and much plundered, but the circuit of the old walls could still be traced, and in several places they were fairly well preserved. They had a circumference of about ten kilometres, and were fortified with towers at regular intervals. Remains of an ancient bath and gymnasium complex can be found within this area; this building is locally known as Bal Saray (Honey Palace) and was originally endowed by Herodes Atticus in the year 135. Trajan built an aqueduct which can still be traced. The harbour had two large basins, now almost choked with sand. It is the subject of an early twenty-first century study by German archaeologists digging and surveying at the site. Their excavation uncovered the remains of a large stadium dating to about 100 BC.

Alexandria, West Dunbartonshire

Alexandria (, ) is a town in West Dunbartonshire, Scotland. The town is on the River Leven, north of Dumbarton and north-west of Glasgow. Demographics In 2016, the estimated population of the town was 6,860. It is one of five towns in the Vale of Leven, the others being Balloch, Bonhill, Jamestown and Renton; their combined population is over 20,000. Economy The town's traditional industries, most importantly cotton manufacturing, bleaching and printing, have been phased out. In the 1970s Alexandria was redeveloped, with a new town centre layout and traffic system. Local landmarks include Christie Park and the Category B listed Smollett Fountain in the town centre. Lomond Galleries on North Main Street is a former car factory with an impressive dome and an even more impressive marble entrance hall and staircase. It was originally built in 1906 as the Argyll Motor Works, for Argyll Motors Ltd. A carving above the entrance shows one of the company's cars. After the car production ceased in 1914, it was used by the Admiralty for the manufacture of torpedoes, which were test-fired in Loch Long, and in the early 1970s was the scene of the Plessey sit-in. The building now hosts a shopping mall but has retained many of its striking architectural features. Major employers in the area were Westclox and Polaroid, both based in the Leven Industrial Estate; Aggreko based a major purpose-built factory in the estate from 2000 to 2010. The Ballantine's whisky distillery continues to operate in the estate. Transport Alexandria sits on the former A82 main road between Glasgow and Loch Lomond. There are regular bus services on the route, and the town has a railway station on the rail line between Balloch and Glasgow Queen Street. Alexandria is reputed to be the only town in the UK with a railway station, carnival (periodically Codona’s travelling fair sets up in the car park) and a pub in the middle of a roundabout. A. J. Cronin's uncle owned a pub in Bridge Street. Alexandria Library is located on Gilmour Street. Sport The town is home to Vale of Leven football club, who play at Millburn Park.

Alexandria, Romania

Alexandria () is the capital city of the Teleorman County, Muntenia, Romania. It is located south-west of Bucharest, towards the Bulgarian border, and has over 45,000 inhabitants. The 44th parallel north passes just north of the city. Geography Alexandria is situated in the middle of the Wallachian Plain, on the banks of the Vedea River. It is located in the central part of Teleorman County, at a distance of from Giurgiu and from Bucharest. The city is traversed by the national road DN6, which links Bucharest to the Banat region in western Romania; the road is part of European route E70. The Alexandria train station serves the CFR Line 909, with service towards Roșiorii de Vede (to the northwest) and Zimnicea (to the south, on the Danube). History Alexandria was named after its founder, Alexandru D. Ghica, Prince of Wallachia from April 1834 to 7 October 1842. Its population in 1900 was 1,675. Grain, which was Alexandria's main trade at the time, was dispatched both by rail to the Danubian port of Zimnicea and by river to Giurgiu. In 1989, the city had over 63,000 inhabitants and more than six large factories. A 2020 estimate puts the population at 49,878. Education There are three high schools in Alexandria: the Alexandru D. Ghica National College, the Alexandru Ioan Cuza Theoretical High School, and the Constantin Noica Theoretical High School.

Angela Vincent

Angela Vincent (born 1942) is Emeritus professor at the University of Oxford and a Fellow of Somerville College, Oxford. Career and research Angela Vincent (nee Molony) was born in 1942, the third child of Joseph and Carmen Molony. After school at St Mary's Convent, Ascot, she studied medicine at King's College London and Westminster Hospital School of Medicine (now merged with Imperial College School of Medicine). After one year as a junior doctor at St Steven's and St Charles' hospitals in London (1966-7), she enrolled as an MSc student in Biochemistry at University College London. In 1967 she married Philip Morse Vincent with whom she had four children. After the MSc, she spent three frustrating years trying to fractionate rat brain synaptosomes, until she was taken on by Ricardo Miledi FRS in the Biophysics Department to work on acetylcholine receptors. During her five years with Miledi, her medical background helped to establish a collaboration on myasthenia gravis with John Newsom-Davis (later FRS); together at the Royal Free Hospital, London, they created a Neuroimmunology Group that subsequently moved with Newsom-Davis to Oxford when he was appointed Action Research Professor of Neurology. After his retirement in 1998, Vincent led the group until 2016. During this time she was Head of the Department of Clinical Neurology (2005-2008) at the University of Oxford, President of the International Society of Neuroimmunology, and an Associate Editor of Brain (2004-2013). Her research group was initially located in the Weatherall Institute of Molecular Medicine at the John Radcliffe Hospital, working on a wide range of biological disciplines encompassing molecular biology, biochemistry, cellular immunology and intracellular neurophysiology. The group's research focused on autoimmune and genetic disorders of the neuromuscular junction, peripheral nerves and more recently the exciting field of central nervous system diseases. The principal autoimmune diseases studied were myasthenia gravis, the Lambert-Eaton myasthenic syndrome, limbic encephalitis, other types of autoimmune encephalitis and acquired neuromyotonia. Her contributions were mainly on the roles of antibodies directed against acetylcholine receptors and muscle specific kinase (MuSK) in myasthenia gravis, and neuronal receptors or potassium channel-associated proteins LGI1, CASPR2 and Contactin-2 in CNS diseases. She demonstrated that transfer of antibodies across the placenta from the pregnant woman to the fetus in utero can cause both acute and longer-term neuromuscular and neurodevelopmental abnormalities. Since 2016 she has been Emeritus Professor at Oxford University, Emeritus Fellow of Somerville College, and holds an honorary appointment at UCL; she continues to work on neuromuscular disorders and advise young researchers. Her work in Oxford on brain disorders continues under Associate Professor Sarosh Irani and Dr Patrick Waters. She is a strong supporter of Freedom from Torture (formerly The Medical Foundation for Treatment of Torture Victims) and a Patron of British Pugwash (that brings together scientists and other concerned with international affairs and disarmament). Awards and honours In 2009, she presented the Leslie Oliver Oration at Queen's Hospital. In 2009, she received the medal of the Association of British Neurologists and in 2017, the World Federation of Neurology Scientific Contributions to Neurology award. In 2015, she was awarded the British Neuroscience Association Award for Outstanding Contribution to Neuroscience. In Cologne 2018, she was awarded with J Posner and J Dalmau, the International Prize for Translational Neuroscience of the Gertrud Reemtsma Foundation (formerly the Klaus Joachim Zülch Prize), and in Washington in 2019, the America Epilepsy Society Clinical Science Research Award (with J Dalmau).Retrieved June 26, 2021, from https://www.ndcn.ox.ac.uk/team/angela-vincent</ref> She received the Inaugural Distinguished Alumni Award, Imperial College, London, 2020.

Arithmetic–geometric mean

In mathematics, the arithmetic–geometric mean of two positive real numbers and is defined as follows: Call and and : Then define the two interdependent sequences and as These two sequences converge to the same number, the arithmetic–geometric mean of and ; it is denoted by , or sometimes by or . The arithmetic–geometric mean is used in fast algorithms for exponential and trigonometric functions, as well as some mathematical constants, in particular, computing . Example To find the arithmetic–geometric mean of and , iterate as follows: The first five iterations give the following values: The number of digits in which and agree (underlined) approximately doubles with each iteration. The arithmetic–geometric mean of 24 and 6 is the common limit of these two sequences, which is approximately . History The first algorithm based on this sequence pair appeared in the works of Lagrange. Its properties were further analyzed by Gauss. Properties The geometric mean of two positive numbers is never bigger than the arithmetic mean (see inequality of arithmetic and geometric means). As a consequence, for , is an increasing sequence, is a decreasing sequence, and . These are strict inequalities if . is thus a number between the geometric and arithmetic mean of and ; it is also between and . If , then . There is an integral-form expression for : where is the complete elliptic integral of the first kind: Indeed, since the arithmetic–geometric process converges so quickly, it provides an efficient way to compute elliptic integrals via this formula. In engineering, it is used for instance in elliptic filter design. The arithmetic–geometric mean is connected to the Jacobi theta function by which upon setting gives Related concepts The reciprocal of the arithmetic–geometric mean of 1 and the square root of 2 is called Gauss's constant, after Carl Friedrich Gauss. In 1799, Gauss proved that where is the lemniscate constant. In 1941, (and hence ) was proven transcendental by Theodor Schneider. The set is algebraically independent over , but the set (where the prime denotes the derivative with respect to the second variable) is not algebraically independent over . The geometric–harmonic mean can be calculated by an analogous method, using sequences of geometric and harmonic means. One finds that . The arithmetic–harmonic mean can be similarly defined, but takes the same value as the geometric mean (see section "Calculation" there). The arithmetic–geometric mean can be used to compute – among others – logarithms, complete and incomplete elliptic integrals of the first and second kind, and Jacobi elliptic functions. Proof of existence From the inequality of arithmetic and geometric means we can conclude that: and thus that is, the sequence is nondecreasing. Furthermore, it is easy to see that it is also bounded above by the larger of and (which follows from the fact that both the arithmetic and geometric means of two numbers lie between them). Thus, by the monotone convergence theorem, the sequence is convergent, so there exists a such that: However, we can also see that: and so: Q.E.D. Proof of the integral-form expression This proof is given by Gauss. Let Changing the variable of integration to , where gives Thus, we have The last equality comes from observing that . Finally, we obtain the desired result Applications The number π For example, according to the Gauss–Legendre algorithm: where with and , which can be computed without loss of precision using Complete elliptic integral K(sinα) Taking and yields the AGM where is a complete elliptic integral of the first kind: That is to say that this quarter period may be efficiently computed through the AGM, Other applications Using this property of the AGM along with the ascending transformations of John Landen, Richard P. Brent suggested the first AGM algorithms for the fast evaluation of elementary transcendental functions (, , ). Subsequently, many authors went on to study the use of the AGM algorithms.

https://en.wikipedia.org/wiki/Akira%20Toriyama

Akira Toriyama

is a Japanese manga artist and character designer. He first achieved mainstream recognition for his highly successful manga series Dr. Slump, before going on to create Dragon Ball (his best-known work) and acting as a character designer for several popular video games such as the Dragon Quest series, Chrono Trigger, and Blue Dragon. Toriyama is regarded as one of the artists that changed the history of manga, as his works are highly influential and popular, particularly Dragon Ball, which many manga artists cite as a source of inspiration. He earned the 1981 Shogakukan Manga Award for best shōnen or shōjo manga with Dr. Slump, and it went on to sell over 35 million copies in Japan. It was adapted into a successful anime series, with a second anime created in 1997, 13 years after the manga ended. His next series, Dragon Ball, would become one of the most popular and successful manga in the world. Having sold 250–300 million copies worldwide, it is the third best-selling manga of all time and is considered to be one of the main reasons for the period when manga circulation was at its highest in the mid-1980s and mid-1990s. Overseas, Dragon Balls anime adaptations have been more successful than the manga and are credited with boosting anime's popularity in the Western world. In 2019, Toriyama was decorated a Chevalier of the French Ordre des Arts et des Lettres for his contributions to the arts. Early life Akira Toriyama was born in Nagoya, Aichi, Japan. He has recalled that when he was in elementary school all of his classmates drew, imitating anime and manga, as a result of not having many forms of entertainment. He believes that he began to advance above everyone else when he started drawing pictures of his friends, and after winning a prize at the local art studio for a picture of One Hundred and One Dalmatians, began to think "art was fun". He was a fan of Hong Kong martial arts films, especially Bruce Lee films such as Enter the Dragon (1973) and Jackie Chan films such as Drunken Master (1978), which later had a major influence on his later work. Another work that had an influence on him was the science fiction film Alien (1979). Career Early work and Dr. Slump (1975-1984) Before becoming a manga artist, he worked at an advertising agency in Nagoya designing posters for three years. After quitting his previous job, Toriyama entered the manga industry by submitting a work to an amateur contest in a Jump magazine in order to win the prize money. While it did not win, Kazuhiko Torishima, who would later become his editor, contacted him and gave him encouragement. His debut came later in 1978 with the story Wonder Island, which was published in Weekly Shōnen Jump. Toriyama would rise to popularity with the comedy series Dr. Slump, which was serialized in Weekly Shōnen Jump from 1980 to 1984. It follows the adventures of a perverted professor and his small but super-strong robot Arale. He began the series at age 25 while living at home with his parents, but when the series ended in 1984 he was a "manga superstar". In 1981, Dr. Slump earned him the Shogakukan Manga Award for best shōnen or shōjo manga series of the year. An anime adaptation began airing that same year, during the prime time Wednesday 19:00 slot on Fuji TV. Adaptations of Toriyama's work would occupy this time slot continuously for 18 years—through Dr. Slumps original run, Dragon Ball and its two sequels, and finally a rebooted Dr. Slump concluding in 1999. By 2008, the Dr. Slump manga had sold over 35 million copies in Japan. An official Toriyama fan club was established in 1982. Its newsletters were called Bird Land Press and were sent to members until the club closed in 1987. Toriyama's founded Bird studio in the early 1980s, which is a play on his name; meaning "bird". He began employing an assistant, mostly to work on backgrounds. Dragon Ball and international success (1984-1995) In 1984, Weekly Shōnen Jump began serializing Toriyama's Dragon Ball, which became an instant hit. As of 2014, it had sold 159.5million tankōbon copies in Japan alone, making it Shueisha's second best-selling manga of all time. It began as an adventure/gag manga but later turned into a martial arts fighting series, considered by many to be the "most influential shōnen manga." Dragon Ball was one of the main reasons for the magazine's circulation hitting a record high of 6.53 million copies (1995). The series' success encouraged Toriyama to continue working on it from 1984 to 1995. At the series' end, Toriyama said that he asked everyone involved to let him end the manga, so he could "take some new steps in life." During that 11-year period, he produced 519 chapters that were collected into 42 volumes. Moreover, the success of the manga led to five anime adaptations, several animated movies, numerous video games, and mega-merchandising. Aside from its popularity in Japan, Dragon Ball was successful internationally as well, including Asia, Europe, and the Americas, with 250–300million copies of the manga sold worldwide. While Toriyama was serializing Dragon Ball weekly, Torishima recruited him to work as character designer for the 1986 role-playing video game Dragon Quest. The artist admitted he was pulled into it without even knowing what an RPG was and that it made his already busy schedule even more hectic, but he was happy to have been a part after enjoying the finished game. Toriyama has continued to work on every installment in the Dragon Quest series. He has also served as the character designer for the Super Famicom RPG Chrono Trigger and for the fighting games Tobal No. 1 and Tobal 2 for the PlayStation. Short stories and other projects (1996-2011) A third anime adaptation based on Dragon Ball- entitled GT began airing in 1996, though this was not based on Toriyama's manga directly. Toriyama was still however involved in some overarching elements, including the name of the series and designs for the main cast. Toriyama continued drawing manga in this period, predominantly one-shots and short (100–200-page) pieces, including Cowa!, Kajika, and Sand Land. On December 6, 2002, Toriyama made his only promotional appearance in the United States at the launch of Weekly Shōnen Jumps North American counterpart, Shonen Jump, in New York City. Toriyama's Dragon Ball and Sand Land were published in the magazine in the first issue, which also included an in-depth interview with him. On March 27, 2005, CQ Motors began selling an electric car designed by Toriyama. The one-person QVOLT is part of the company's Choro-Q series of small electric cars, with only 9 being produced. It costed 1,990,000 yen (about $19,000 US), has a top speed of and was available in 5 colors. Toriyama stated that the car took over a year to design, "but due to my genius mini-model construction skills, I finally arrived at the end of what was a very emotional journey." He worked on a 2006 one-shot called Cross Epoch, in cooperation with One Piece creator Eiichiro Oda. The story is a short crossover that presents characters from both Dragon Ball and One Piece. Toriyama was the character designer and artist for the 2006 Mistwalker Xbox 360 exclusive RPG Blue Dragon, working with Hironobu Sakaguchi and Nobuo Uematsu, both of whom he had previously worked with on Chrono Trigger. At the time, Toriyama considered Blue Dragon to potentially be his final work in anime. In 2008, he collaborated with Masakazu Katsura, his good friend and creator of I"s and Zetman, for the Jump SQ one-shot Sachie-chan Good!!. It was later published in North America in the free SJ Alpha Yearbook 2013, which was mailed out to annual subscribers of the digital manga magazine Shonen Jump Alpha in December 2012. The two worked together again in 2009, for the three-chapter one-shot Jiya in Weekly Young Jump. An American live action film adaptation of Dragon Ball released in 2009, entitled Dragonball Evolution which have no involvement with Toriyama, Toei, and Funimation and the film failed both critically and financially. Avex Trax commissioned Toriyama to draw a portrait of pop singer Ayumi Hamasaki; it was printed on the CD of her 2009 single "Rule/Sparkle", which was used as the theme song to the film. Toriyama drew a 2009 manga titled Delicious Island's Mr. U for Anjō's Rural Society Project, a nonprofit environmental organization that teaches the importance of agriculture and nature to young children. They originally asked him to do the illustrations for a pamphlet, but Toriyama liked the project and decided to expand it into a story. It is included in a booklet about environmental awareness that is distributed by the Anjō city government. As part of Weekly Shōnen Jumps "Top of the Super Legend" project, a series of six one-shots by famed Jump artists, Toriyama created Kintoki for its November 15, 2010 issue. He collaborated with Weekly Shōnen Jump to create a video to raise awareness and support for those affected by the 2011 Tōhoku earthquake and tsunami on March 11, 2011. Return to Dragon Ball: 2012–present In 2012, Dragon Ball Z: Battle of Gods was announced to be in development, with Toriyama involved in its design. The film marked the series' first theatrical film in 17 years, and the first time Toriyama had been involved in an anime project as early as the screenwriting stages. The film opened on March 30, 2013. A special "dual ticket" that could be used to see both Battle of Gods and One Piece Film: Z was created with new art by both Toriyama and Eiichiro Oda. On March 27, the "Akira Toriyama: The World of Dragon Ball" exhibit opened at the Takashimaya department store in Nihonbashi, garnering 72,000 visitors in its first nineteen days. The exhibit is separated into seven areas. The first provides a look at the series' history, the second shows the 400-plus characters from the series, the third displays Toriyama's manga manuscripts from memorable scenes, the fourth shows special color illustrations, the fifth displays rare Dragon Ball-related materials, the sixth includes design sketches and animation cels from the anime, and the seventh screens Dragon Ball-related videos. It was there until April 15, when it moved to Osaka from April 17 to 23, and ended in Toriyama's native Nagoya from July 27 to September 1. To celebrate the 45th anniversary of Weekly Shōnen Jump, Toriyama launched a new series in its July 13, 2013 issue titled Jaco the Galactic Patrolman. Viz Media began serializing it in English in their digital Weekly Shonen Jump magazine, beginning just two days later. The final chapter reveals that the story is set before the events of Dragon Ball and features some of its characters. The follow-up film to Battle of Gods, Resurrection 'F', released on April 18, 2015, features even more contributions from Toriyama, who personally wrote its original script. Toriyama provides the basic story outline and some character designs for Dragon Ball Super, which began serialization in V Jump in June 2015 with an anime counterpart following in July. Although the anime ended in 2018, he continues to provide story ideas for the manga while Toyotarou illustrates it. Dragon Ball Super: Broly, released in theaters on December 14, 2018, continued Toriyama's deep involvement with the films. Personal life Toriyama married on May 2, 1982. She is a former manga artist from Nagoya under the pen name , and occasionally helped Toriyama and his assistant on Dr. Slump when they were short on time. They have two children: a son named born on March 23, 1987, and a daughter born in October 1990. Toriyama lives in his home studio in Kiyosu. He is a well-known recluse, who avoids appearing in public or media. Toriyama has a love of cars and motorcycles, something he inherited from his father who used to race motorbikes and operated an auto repair business for a brief time, although he does not understand the mechanics himself. The author is an animal lover, having kept many different species of birds, dogs, cats, fish, lizards, and bugs as pets since childhood. Some were used as models for characters he created such as Karin and Beerus. Toriyama has had a lifelong passion for plastic models, and has designed several for the Fine Molds brand. He also collected autographs of famous manga artists, having over 30 including Yudetamago and Hisashi Eguchi, a hobby he gave to Peasuke Soramame. Style Toriyama admires Osamu Tezuka's Astro Boy and was impressed by Walt Disney's One Hundred and One Dalmatians, which he remembers for its high-quality animation. Jackie Chan's early movies also had a noticeable influence on his stories, particularly Chan's martial arts comedy film Drunken Master. Toriyama stated he was influenced by animator Toyoo Ashida and the anime television series adaptation of his own Dragon Ball; from which he learned that separating colors instead of blending them makes the art cleaner and coloring illustrations easier. It was Toriyama's sound effects in Mysterious Rain Jack that caught the eye of Kazuhiko Torishima, who explained that usually they are written in katakana, but Toriyama used the Roman alphabet which he found refreshing. In his opinion, Torishima stated that Toriyama excels in black and white, utilizing black areas, as a result of not having had the money to buy screentone when he started drawing manga. He also described Toriyama as a master of convenience and "sloppy, but in a good way." For instance, in Dragon Ball, destroying scenery in the environment and giving Super Saiyans blond hair were done in order to have less work in drawing and inking. Torishima claimed that Toriyama draws what he finds interesting and is not mindful of what his readers think. Dr. Slump is mainly a comedy series, filled with puns, toilet humor, and sexual innuendos. But it also contained many science fiction elements: aliens, anthropomorphic characters, time travel, and parodies of works such as Godzilla, Star Wars, and Star Trek. Toriyama also included many real-life people in the series, such as his assistants, wife, and colleagues (such as Masakazu Katsura), but most notably his editor Kazuhiko Torishima as the series' main antagonist, Dr. Mashirito. A running gag in Dr. Slump that utilizes feces has been reported as an inspiration for the Pile of Poo emoji. When Dragon Ball began, it was loosely based on the classic Chinese novel Journey to the West, with Goku being Sun Wukong and Bulma as Tang Sanzang. It was also inspired by Hong Kong martial arts films, particularly those of Jackie Chan, and was set in a fictional world based on Asia, taking inspiration from several Asian cultures including Japanese, Chinese, Indian, Central Asian, Arabic, and Indonesian cultures. Toriyama continued to use his characteristic comedic style in the beginning, but over the course of time this slowly changed, with him turning the series into a "nearly-pure fighting manga" later on. He did not plan out in advance what would happen in the series, instead choosing to draw as he went. This, coupled with him simply forgetting things he had already drawn, caused him to find himself in situations that he had to write himself out of. Toriyama was commissioned to illustrate the characters and monsters for the first Dragon Quest video game (1986) in order to separate it from other role-playing games of the time. He has since worked on every installment in the series. For each game Yuji Horii first sends rough sketches of the characters with their background information to Toriyama, who then re-draws them. Lastly, Horii approves the finished work. Toriyama explained in 1995 that for video games, because the sprites are so small, as long as they have a distinguishing feature so people can tell which character it is, he can make complex designs without concern of having to reproduce it like he usually would in manga. Besides the character and monster designs, Toriyama also does the games' packaging art and, for Dragon Quest VIII, the boats and ships. In 2016, Toriyama revealed that because of the series' established time period and setting, his artistic options are limited, which makes every iteration harder to design for than the last. The series' Slime character, which has become a mascot for the franchise, is considered to be one of the most recognizable figures in gaming. Manga critic Jason Thompson declared Toriyama's art influential, saying that his "extremely personal and recognizable style" was a reason for Dragon Ball'''s popularity. He points out that the popular shōnen manga of the late 1980s and early 1990s had "manly" heroes, such as City Hunter and Fist of the North Star, whereas Dragon Ball starred the cartoonish and small Goku, thus starting a trend that Thompson says continues to this day. Toriyama himself said he went against the normal convention that the strongest characters should be the largest in terms of physical size, designing many of the series' most powerful characters with small statures. Thompson concluded his analysis by saying that only Akira Toriyama drew like this at the time and that Dragon Ball is "an action manga drawn by a gag manga artist." However, James S. Yadao, author of The Rough Guide to Manga, points out that an art shift does occur in the series, as the characters gradually "lose the rounded, innocent look that [Toriyama] established in Dr. Slump and gain sharper angles that leap off the page with their energy and intensity." Legacy and accolades Thompson stated in 2011 that "Dragon Ball is by far the most influential shonen manga of the last 30 years, and today, almost every Shōnen Jump artist lists it as one of their favorites and lifts from it in various ways." David Brothers of ComicsAlliance wrote that: "Like Osamu Tezuka and Jack Kirby before him, Toriyama created a story with his own two hands that seeped deep into the hearts of his readers, creating a love for both the cast and the medium at the same time." In a rare 2013 interview, commenting on Dragon Balls global success, Toriyama admitted, "Frankly, I don't quite understand why it happened. While the manga was being serialized, the only thing I wanted as I kept drawing was to make Japanese boys happy." Many artists have named Toriyama and Dragon Ball as influences, including One Piece author Eiichiro Oda, Naruto creator Masashi Kishimoto, Fairy Tail and Rave author Hiro Mashima, Boruto: Naruto Next Generations illustrator Mikio Ikemoto, Venus Versus Virus author Atsushi Suzumi, Bleach creator Tite Kubo, Black Cat author Kentaro Yabuki, and Mr. Fullswing author Shinya Suzuki. German comic book artist Hans Steinbach was strongly influenced by Toriyama, and Thai cartoonist Wisut Ponnimit cited Toriyama as one of his favorite cartoonists. Ian Jones-Quartey, a producer of the American animated series Steven Universe, is a fan of both Dragon Ball and Dr. Slump, and uses Toriyama's vehicle designs as reference for his own. He also stated that "We're all big Toriyama fans on [Steven Universe], which kind of shows a bit." In 2008, Oricon conducted a poll of people's favorite manga artists, with Toriyama coming in second, behind only Nana author Ai Yazawa. However, he was number one among male respondents and among those over 30 years of age. They held a poll on the Mangaka that Changed the History of Manga in 2010, mangaka being the Japanese word for a manga artist. Toriyama came in second, after only Osamu Tezuka, due to his works being highly influential and popular worldwide. Toriyama won the Special 40th Anniversary Festival Award at the 2013 Angoulême International Comics Festival, honoring his years in cartooning. He actually received the most votes for the festival's Grand Prix de la ville d'Angoulême award that year; however, the selection committee chose Willem as the recipient. In a 2014 NTT Docomo poll for the manga artist that best represents Japan, Toriyama came in third place. Toriyama was decorated a Chevalier or "Knight" of the Ordre des Arts et des Lettres by the French government on May 30, 2019 for his contributions to the arts. He was also a 2019 nominee for entry into the Will Eisner Hall of Fame. Due to his video game design work, IGN named Toriyama number 74 on their list of the Top 100 Game Creators of All Time.

Epsilon Ursae Majoris

Epsilon Ursae Majoris (Latinised from ε Ursae Majoris, abbreviated Epsilon UMa, ε UMa), officially named Alioth , is, despite being designated "ε" (epsilon), the brightest star in the constellation of Ursa Major, and at magnitude 1.77 is the thirty-third brightest star in the sky. It is the star in the tail of the bear closest to its body, and thus the star in the handle of the Big Dipper (or Plough) closest to the bowl. It is also a member of the large and diffuse Ursa Major moving group. Historically, the star was frequently used in celestial navigation in the maritime trade, because it is listed as one of the 57 navigational stars. Physical characteristics According to Hipparcos, Epsilon Ursae Majoris is from the Sun. Its spectral type is A1p; the "p" stands for peculiar, as its spectrum is characteristic of an α2 Canum Venaticorum variable. Epsilon Ursae Majoris, as a representative of this type, may harbor two interacting processes. First, the star's strong magnetic field separating different elements in the star's hydrogen 'fuel'. In addition, a rotation axis at an angle to the magnetic axis may be spinning different bands of magnetically sorted elements into the line of sight between Epsilon Ursae Majoris and the Earth. The intervening elements react differently at different frequencies of light as they whip in and out of view, causing Epsilon Ursae Majoris to have very strange spectral lines that fluctuate over a period of 5.1 days. The kB9 suffix to the spectral type indicates that the calcium K line is present and representative of a B9 spectral type even though the rest of the spectrum indicates A1. Epsilon Ursae Majoris's rotational and magnetic poles are at almost 90 degrees to one another. Darker (denser) regions of chromium form a band at right angles to the equator. It has long been suspected that Epsilon Ursae Majoris is a spectroscopic binary, possibly with more than one companion. A more recent study suggests Epsilon Ursae Majoris's 5.1-day variation may be due to a substellar object of about 14.7 Jupiter masses in an eccentric orbit (e=0.5) with an average separation of 0.055 astronomical units. It is now thought that the 5.1-day period is the rotation period of the star, and no companions have been detected using the most modern equipment. Epsilon Ursae Majoris has a relatively weak magnetic field, 15 times weaker than α Canum Venaticorum, but it is still 100 times stronger than that of the Earth. Name and etymology ε Ursae Majoris (Latinised to Epsilon Ursae Majoris) is the star's Bayer designation. The traditional name Alioth comes from the Arabic alyat al-hamal ("the sheep's fat tail"). In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included Alioth for this star. This star was known to the Hindus as Añgiras, one of the Seven Rishis. In Chinese, (), meaning Northern Dipper, refers to an asterism equivalent to the Big Dipper. Consequently, the Chinese name for Epsilon Ursae Majoris itself is (, ) and (, ). Namesakes USS Allioth (AK-109) was a United States Navy Crater class cargo ship named after the star.

Amiga 500

The Amiga 500, also known as the A500, is the first low-end version of the Amiga home computer. It contains the same Motorola 68000 as the Amiga 1000, as well as the same graphics and sound coprocessors, but is in a smaller case similar to that of the Commodore 128. Commodore announced the Amiga 500 at the January 1987 winter Consumer Electronics Showat the same time as the high-end Amiga 2000. It was initially available in the Netherlands in April 1987, then the rest of Europe in May. In North America and the UK it was released in October 1987 with a list price. It competed directly against models in the Atari ST line. The Amiga 500 was sold in the same retail outlets as the Commodore 64, as opposed to the computer store-only Amiga 1000. It proved to be Commodore's best-selling model, particularly in Europe. Although popular with hobbyists, arguably its most widespread use was as a gaming machine, where its graphics and sound were of significant benefit. It was followed by a revised version of the computer, the Amiga 500 Plus, and the 500 series was discontinued in 1992. Releases In October 1989, the Amiga 500 dropped its price from £499 to £399 and was bundled with the Batman Pack in the United Kingdom (from October 1989 to September 1990) which included the games Batman, F/A-18 Interceptor, The New Zealand Story and the bitmap graphics editor Deluxe Paint 2. Also included was the Amiga video connector which allows the A500 to be used with a conventional CRT television. In November 1991, the enhanced Amiga 500 Plus replaced the 500 in some markets. It was bundled with the Cartoon Classics pack in the United Kingdom at £399, although many stores still advertised it as an 'A500'. The Amiga 500 Plus was virtually identical except for its new operating system, and in mid-1992, the two were discontinued and effectively replaced by the Amiga 600. In late 1992, Commodore released the Amiga 1200, a machine closer in concept to the original Amiga 500, but with significant technical improvements. Despite this, neither the A1200 nor the A600 replicated the commercial success of its predecessor. By this time, the home market was strongly shifting to IBM PC compatibles with VGA graphics and the "low-cost" Macintosh Classic, LC, and IIsi models. Description Outwardly resembling the Commodore 128 and codenamed "Rock Lobster" during development, the Amiga 500's base houses a keyboard and a CPU in one shell, unlike the Amiga 1000. The keyboard for Amiga 500s sold in the United States contains 94 keys, including ten function keys, four cursor keys, and a number pad. All European versions the keyboard have an additional two keys, except for the British variety, which still uses 94 keys. It uses a Motorola 68000 microprocessor running at in NTSC regions and in PAL regions. The CPU implements a 32-bit model and has 32-bit registers, but it has a 16-bit main ALU and uses a 16-bit external data bus and a 23-bit address bus, providing a maximum of 16 MB of address space. Also built in to the base of the computer is a -inch floppy disk drive. The user can also install up to three external floppy drives, either - or -inch, via the disk drive port. The second and third additional drives are installed by daisy-chaining them. Supported by these drives are double-sided disks with a capacity of 901,120 bytes, as well as 360- and 720-KB disks formatted for IBM PC compatibles. The earliest Amiga 500 models use nearly the same Original Amiga chipset as the Amiga 1000. So graphics can be displayed in multiple resolutions and color depths, even on the same screen. Resolutions vary from 320×200 (up to 32 colors) to 640×400 (up to 16 colors) for NTSC (704×484 overscan) and 320×256 to 640×512 for PAL (704×576 overscan.) The system uses planar graphics, with up to five bitplanes (four in high resolution) allowing 2-, 4-, 8-, 16-, and 32-color screens, from a palette of 4096 colors. Two special graphics modes are also available: Extra HalfBrite, which uses a 6th bitplane as a mask to cut the brightness of any pixel in half (resulting in 32 arbitrary colors plus 32 more colors set at half the value of the first 32), and Hold-And-Modify (HAM) which allows all 4096 colors to be used on screen simultaneously. Later revisions of the chipset are PAL/NTSC switchable in software. The sound chip produces four hardware-mixed channels, two to the left and two to the right, of 8-bit PCM at a sampling frequency up to . Each hardware channel has its own independent volume level and sampling rate, and can be designated to another channel where it can modulate both volume and frequency using its own output. With DMA disabled it's possible to output with a sampling frequency up to . There is a common trick to output sound with 14-bit precision that can be combined to output 14-bit sound. The stock system comes with AmigaOS version 1.2 or 1.3 and of chip RAM (150 ns access time), one built-in double-density standard floppy disk drive that is completely programmable and can read IBM PC disks, standard Amiga disks, and up to using custom-formatting drivers. Despite the lack of Amiga 2000-compatible internal expansion slots, there are many ports and expansion options. There are two DE9M Atari joystick ports for joysticks or mice, and stereo audio RCA connectors (1 V p-p). There is a floppy drive port for daisy-chaining up to three extra floppy disk drives via a DB23F connector. The then-standard RS-232 serial port (DB25M) and Centronics parallel port (DB25F) are also included. The power supply is (, ). The system displays video in analog RGB PAL or NTSC through a proprietary DB23M connector and in NTSC mode the line frequency is HSync for standard video modes, which is compatible with NTSC television and CVBS/RGB video, but out of range for most VGA-compatible monitors, while a multisync monitor is required for some of the higher resolutions. This connection can also be genlocked to an external video signal. The system was bundled with an RF adapter to provide output on televisions with a coaxial RF input, while monochrome composite video is available via an RCA connector (also coaxial). On the left side, behind a plastic cover, there is a Zorro (Zorro I) bus expansion external edge connector with 86 pins. Peripherals such as a hard disk drive can be added via the expansion slot and are configured automatically by the Amiga's AutoConfig standard, so that multiple devices do not conflict with each other. Up to of so-called "fast RAM" (memory that can be accessed by the CPU only) can be added using the side expansion slot. This connector is electronically identical with the Amiga 1000's, but swapped on the other side. The Amiga 500 has a "trap-door" slot on the underside for a RAM upgrade (typically ). This extra RAM is classified as "fast" RAM, but is sometimes referred to as "slow" RAM: due to the design of the expansion bus, it is actually on the chipset bus. Such upgrades usually include a battery-backed real-time clock. All versions of the A500 can have the additional RAM configured as chip RAM by a simple hardware modification, which involves fitting a later model (8372A) Agnus chip. Likewise, all versions of the A500 can be upgraded to chip RAM by fitting the chip and adding additional memory. The Amiga 500 also sports an unusual feature for a budget machine, socketed chips, which allow easy replacement of defective chips. The CPU can be directly upgraded on the motherboard to a 68010; or to a 68020, 68030, or 68040 via the side expansion slot; or by removing the CPU and plugging a CPU expansion card into the CPU socket (this requires opening the computer and thus voided any remaining warranty). In fact, all the custom chips can be upgraded to the Amiga Enhanced Chip Set (ECS) versions. The plastic case is made of acrylonitrile butadiene styrene, or ABS. ABS degrades with time due to exposure to oxygen, causing a yellowing of the case. Other factors contributing to the degradation and yellowing include heat, shear, and ultraviolet light. The yellowing can be reversed by using an optical brightener, though without stabilizing agents or antioxidants to block oxygen, the yellowing will return. Technical specifications OCS (1.2 & 1.3 models) or ECS (1.3 and 500+ 2.04 models) chipset. ECS revisions of the chipset made PAL/NTSC mode switchable in software. Sound: 4 hardware-mixed channels of 8-bit sound at up to . The hardware channels have independent volumes (65 levels) and sampling rates, and are mixed down to two fully left and fully right stereo outputs. A software controllable low-pass audio filter is also included. 512 KB of chip RAM (150 ns access time). AmigaOS 1.2 or 1.3 (upgradeable up to 3.1.4 if 2 MB of RAM are installed) One 3.5" double-density floppy disk drive is built in, which is completely programmable and thus can read IBM PC disks, standard Amiga disks, and up to with custom formatting (such as Klaus Deppich's diskspare.device). Uses (5 rotations/second) and . Built-in keyboard. A two-button mouse is included. Graphics PAL mode: 320×256, 640×256, 640×512 (interlaced), 704×576 in overscan. NTSC mode: 320×200, 640×200, 640×400 (interlaced), 704×484 in overscan. Graphics can be of arbitrary dimensions, resolution and colour depth, even on the same screen. The Amiga can show multiple resolution modes at the same time, splitting the screen vertically. Planar graphics are used, with up to 5 bitplanes (4 in hires); this allowed 2, 4, 8, 16 and 32 colour screens, from a palette of 4096 colours. Two special graphics modes are also included: Extra HalfBrite (EHB), which uses a 6th bitplane as a mask that halved the brightness of any colour seen Hold-And-Modify (HAM), which allows all 4096 colours on screen at once. HAM makes it possible to use over a wide span. This works by letting each pixel position use the previous RGB value and modify one of the red, green or blue values to a new 4-bit value. This will cause some negligible colour artifacts however. Memory Using various expansion techniques, the A500's total RAM can reach up to 138 MB – 2 MB Chip RAM, 8 MB 16-bit Fast RAM, and 128 MB 32-bit Fast RAM. Chip RAM The stock 512 KB Chip RAM can be complemented by 512 KB using a "trapdoor" expansion (Commodore A501 or compatible). While that expansion memory is connected to the chip bus, hardware limitations of the stock Agnus chip prevent its use as Chip RAM, only the CPU can access it. Suffering from the same contention limitations as Chip RAM, that memory is known as "Slow RAM" or "Pseudo-fast RAM". Retrofitting a later ECS Agnus and changing the memory-layout jumper allows use of trapdoor RAM as real Chip RAM for a total 1 MB. Additionally, several third-party expansions exist with up to 1.8 MB on the trapdoor board. Using a Gary adapter, that memory is mapped similar to the standard Slow RAM and only usable by the CPU, yet slowed by chipset access. Furthermore, using an A3000 Agnus on an adapter board, it is possible to expand the Chip RAM to 2 MB. Fast RAM "Fast" RAM is located on the CPU-side bus. Its access is exclusive to the CPU and not slowed by any chipset access. The side expansion port allows for up to 8 MB of Zorro-style expansion RAM. Alternatively, a CPU adapter allows for internal expansion. Accelerator RAM Internal or external CPU accelerators often include their own expansion memory. 16-bit CPUs are limited by the 24-bit address space but they can repurpose otherwise unused memory space for their included RAM. 32-bit CPU accelerators aren't limited by 24-bit addressing and can include up to 128 MB of Fast RAM (and potentially more). Memory map Connectors Two Atari joystick ports for joysticks or mice Stereo audio RCA connectors (1 V p-p) A floppy drive port (DB23F), for daisy-chaining up to 3 extra floppy disk drives via a DB23F connector A standard RS-232 serial port (DB25M) A parallel port (DB25F) Power inlet (, ) Analogue RGB 50 Hz PAL and NTSC video output, provided on an Amiga-specific DB23M video connector. Can drive video with HSync for standard Amiga video modes. This is not compatible with most VGA monitors. A Multisync monitor is required for some higher resolutions. This connection can also be genlocked to an external video signal. An RF adapter (A520) was frequently bundled with the machine to provide output on regular televisions or on composite monitors. A digital 16 colour Red-Green-Blue-Intensity signal is available too on the same connector. Monochrome video via an RCA connector Zorro II bus expansion on the left side behind a plastic cover Trapdoor slot under the machine, for RAM expansion and real-time clock Expansions Expansion ports are limited to a side expansion port and a trapdoor expansion on the underside of the machine. The casing can also be opened up (voiding the warranty), all larger chips are socketed rather than being TH/SMD soldered directly to the motherboard, so they can be replaced by hand. The CPU can be upgraded to a Motorola 68010 directly or to a 68020, 68030 or 68040 via the side expansion slot or a CPU socket adapter board. The chip RAM can be upgraded to directly on the motherboard, provided a Fat Agnus chip is also installed to support it. Likewise, all the custom chips can be upgraded to the ECS chipset. The A500+ model instead allowed upgrading by trapdoor chip RAM without clock, but there was no visible means on board to map any of this as FAST, causing incompatibility with some stubbornly coded programs. There were modification instructions available for the A500 to solder or socket another RAM on the board, then run extra address lines to the trapdoor slot to accommodate an additional of fast or chip RAM depending on the installed chipset. Up to of "fast RAM" can be added via the side expansion slot, even more if an accelerator with a non-EC (without reduced data/address bus) processor and 32-bit RAM is used. Hard drive and other peripherals can be added via the side expansion slot. Several companies provided combined CPU, memory and hard drive upgradesor provided chainable expansions that extended the bus as they were addedas there is only one side expansion slot. Expansions are configured automatically by AutoConfig software, so multiple pieces of hardware did not conflict with each other. Diagnostics When the computer is powered on a self-diagnostic test is run that will indicates failure with a specific colour: Medium green means no chip RAM found or is damaged. Red means bad kickstart-ROM. Yellow means the CPU has crashed (no trap routine or trying to run bad code) or a bad Zorro expansion card. Blue means a custom chip problem (Denise, Paula, or Agnus). Light green means CIA problem. Light gray means that the CIA might be defective. mean there is a ROM or CIA problem. Black-only (no video) means there is no video output. The keyboard LED uses blink codes: One blink means the keyboard ROM has a checksum error. Two blinks means RAM failure. Three blinks means watchdog timer failure. Trap-door expansion 501 A popular expansion for the Amiga 500 was the Amiga 501 circuit board that can be installed underneath the computer behind a plastic cover. The expansion contains RAM configured by default as "Slow RAM" or "trap-door RAM" and a battery-backed real-time clock (RTC). The 512 KB trap-door RAM and 512 KB of original chip RAM will result in 1 MB of total memory. By default, the expansion memory is handled and reported by the system as fast memory. However, the RAM is physically connected to Agnus like chip RAM and it is impacted by chip-bus bandwidth contention. Being only accessible by the CPU but as slow as chip RAM, it is commonly being referred to as "Slow RAM". The motherboard can be modified to relocate the trap-door RAM to the chip memory pool, provided a compatible Agnus chip is fitted on the motherboard. Software Each time the Amiga 500 is booted, it executes code from the Kickstart ROM. The Amiga 500 initially came shipped with AmigaOS 1.2, but units since October 1988 had version 1.3 installed. Reception and sales The Amiga 500 was the best-selling model in the Amiga family of computers. The German computer magazine Chip awarded the model the annual "Home Computer of the Year" title three consecutive times. At the European Computer Trade Show 1991, it also won the Leisure Award for the similar "Home Computer of the Year" title. Owing to the inexpensive cost of the Amiga 500 in then price-sensitive Europe, sales of the Amiga family of computers were strongest there, constituting 85 percent of Commodore's total sales in the fourth quarter of 1990. The Amiga 500 was widely perceived as a gaming machine and the Amiga 2000 a computer for artists and hobbyists. It has been claimed that Commodore sold as many as six million units worldwide. However, Commodore UK refuted that figure and said that the entire Amiga line sold between four and five million computers. Indeed, Ars Technica provides a year-by-year graph of the sales of all Amiga computers. Amiga 500 Plus The Amiga 500 Plus (often A500 Plus or simply A500+) is a revised version of the original Amiga 500 computer. The A500+ featured minor changes to the motherboard to make it cheaper to produce than the original A500. It was notable for introducing new versions of Kickstart and Workbench, and for some minor improvements in the custom chips, known as the Enhanced Chip Set (or ECS). Although officially introduced in 1992, some Amiga 500 units sold in late 1991 actually featured the revised motherboard used in the A500+. Although the Amiga 500+ was an improvement to the Amiga 500, it was minor. It was discontinued and replaced by the Amiga 600 in summer 1992, making it the shortest-lived Amiga model. Compatibility problems Due to the new Kickstart v2.04, quite a few popular games (such as Treasure Island Dizzy, SWIV, and Lotus Esprit Turbo Challenge) failed to work on the Amiga 500+, and some people took them back to dealers demanding an original Kickstart 1.3 Amiga 500. This problem was solved by third parties who produced Kickstart ROM switching boards, that could allow the Amiga 500+ to be downgraded to Kickstart 1.2 or 1.3. It also encouraged game developers to use better programming habits, which was important since Commodore already had plans for the introduction of the next-generation Amiga 1200 computer. A program, Relokick, was also released (and included with an issue of CU Amiga) which loaded a Kickstart 1.3 ROM image into memory and booted the machine into Kickstart 1.3, allowing incompatible software to run. In some cases, updated compatible versions of games were later released, such as budget versions of Lotus 1 and SWIV. Double Dragon 2 by Binary Design received an update for ECS machines with the "Amiga phase-alternated linescan version 4.01/ECS". This solved compatibility issues with the graphics which appeared garbled on ECS machines, and it also slashed the in-game loading times from around 20 seconds to just over 6. Technical specifications Motorola 68000 CPU running at (PAL) / (NTSC), like its predecessor 1 MB of Chip RAM (very early versions came with 512 KB) Kickstart 2.04 (v37.175) Workbench 37.67 (release 2.04) Built-in battery backed RTC (Real Time Clock) Full ECS chipset including new version of the Agnus chip and Denise chip Remake Retro Games, which previously released THEC64, a 2018 microconsole that emulated the Commodore 64, announced in August 2021 The A500 Mini (stylized as THEA500 Mini), a similar microconsole that will emulate the Amiga 500 as well as the Amiga 600 and Amiga 1200. In addition to 25 Amiga 500 games that will ship with the unit, users will be able to sideload other games from a USB drive with WHDLoad support. The unit will ship with a two-button mouse that is molded after the original, and an eight-button gamepad, both of which connect via USB. Like the Commodore 64, the Amiga 500 shipped in a large keyboard form factor, and so too does The A500 Mini. The system draws power from a USB-C cable and outputs to 720p at 60 Hz in the US, or 50 Hz in Europe. There are multiple scaling options, a CRT filter, the ability to save and resume progress in games, and upgradeable firmware. It is expected to ship on March 25, 2022. The system will include 25 games: Alien Breed 3D Alien Breed: Special Edition ’92 Another World Arcade Pool ATR: All Terrain Racing Battle Chess Cadaver California Games The Chaos Engine Dragons Breath F-16 Combat Pilot Kick Off 2 The Lost Patrol Paradroid 90 Pinball Dreams Project-X: Special Edition ’93 Qwak The Sentinel Simon the Sorcerer Speedball 2: Brutal Deluxe Stunt Car Racer Super Cars II Titus the Fox Worms: The Director's Cut Zool: Ninja of the Nth Dimension See also Amiga models and variants Minimigan FPGA implementation Notes References Further reading External links Amiga 500 Buyers guide Amiga Products introduced in 1987 68000-based home computers

Amiga 1000

The Commodore Amiga 1000, also known as the A1000 and originally marketed as the Amiga, is the first personal computer released by Commodore International in the Amiga line. It combines the 16/32-bit Motorola 68000 CPU which was powerful by 1985 standards with one of the most advanced graphics and sound systems in its class, and runs a preemptive multitasking operating system that fits into of read-only memory and shipped with 256 KB of RAM. The primary memory can be expanded internally with a manufacturer-supplied 256 KB module for a total of 512 KB of RAM. Using the external slot the primary memory can be expanded up to Design The A1000 has a number of characteristics that distinguish it from later Amiga models: It is the only model to feature the short-lived Amiga check-mark logo on its case, the majority of the case is elevated slightly to give a storage area for the keyboard when not in use (a "keyboard garage"), and the inside of the case is engraved with the signatures of the Amiga designers (similar to the Macintosh); including Jay Miner and the paw print of his dog Mitchy. The A1000's case was designed by Howard Stolz. As Senior Industrial Designer at Commodore, Stolz was the mechanical lead and primary interface with Sanyo in Japan, the contract manufacturer for the A1000 casing. The Amiga 1000 was manufactured in two variations: One uses the NTSC television standard and the other uses the PAL television standard. The NTSC variant was the initial model manufactured and sold in North America. The later PAL model was manufactured in Germany and sold in countries using the PAL television standard. The first NTSC systems lack the EHB video mode which is present in all later Amiga models. Because AmigaOS was rather buggy at the time of the A1000's release, the OS was not placed in ROM then. Instead, the A1000 includes a daughterboard with 256 KB of RAM, dubbed the "writable control store" (WCS), into which the core of the operating system is loaded from floppy disk (this portion of the operating system is known as the "Kickstart"). The WCS is write-protected after loading, and system resets do not require a reload of the WCS. In Europe, the WCS was often referred to as WOM (Write Once Memory), a play on the more conventional term "ROM" (read-only memory). Technical information The preproduction Amiga (which was codenamed "Velvet") released to developers in early 1985 contained of RAM with an option to expand it to Commodore later increased the system memory to due to objections by the Amiga development team. The names of the custom chips were different; Denise and Paula were called Daphne and Portia respectively. The casing of the preproduction Amiga was almost identical to the production version: the main difference being an embossed Commodore logo in the top left corner. It did not have the developer signatures. The Amiga 1000 has a Motorola 68000 CPU running at 7.15909 MHz (on NTSC systems) or 7.09379 MHz (PAL systems), precisely double the video color carrier frequency for NTSC or 1.6 times the color carrier frequency for PAL. The system clock timings are derived from the video frequency, which simplifies glue logic and allows the Amiga 1000 to make do with a single crystal. In keeping with its video game heritage, the chipset was designed to synchronize CPU memory access and chipset DMA so the hardware runs in real time without wait-state delays. Though most units were sold with an analog RGB monitor, the A1000 also has a built-in composite video output which allows the computer to be connected directly to some monitors other than their standard RGB monitor. The A1000 also has a "TV MOD" output, into which an RF Modulator can be plugged, allowing connection to a TV that was old enough not to even have a composite video input. The original 68000 CPU can be directly replaced with a Motorola 68010, which can execute instructions slightly faster than the 68000 but also introduces a small degree of software incompatibility. Third-party CPU upgrades, which mostly fit in the CPU socket, use faster successors 68020/68881 or 68030/68882 microprocessors and integrated memory. Such upgrades often have the option to revert to 68000 mode for full compatibility. Some boards have a socket to seat the original 68000, whereas the 68030 cards typically come with an on-board 68000. The original Amiga 1000 is the only model to have 256 KB of Amiga Chip RAM, which can be expanded to 512 KB with the addition of a daughterboard under a cover in the center front of the machine. RAM may also be upgraded via official and third-party upgrades, with a practical upper limit of about 9 MB of "fast RAM" due to the 68000's 24-bit address bus. This memory is accessible only by the CPU permitting faster code execution as DMA cycles are not shared with the chipset. The Amiga 1000 features an 86-pin expansion port (electrically identical to the later Amiga 500 expansion port, though the A500's connector is inverted). This port is used by third-party expansions such as memory upgrades and SCSI adapters. These resources are handled by the Amiga Autoconfig standard. Other expansion options are available including a bus expander which provides two Zorro-II slots. Specifications Retail Introduced on July 23, 1985, during a star-studded gala featuring Andy Warhol and Debbie Harry held at the Vivian Beaumont Theater at Lincoln Center in New York City, machines began shipping in September with a base configuration of 256 KB of RAM at the retail price of . A analog RGB monitor was available for around , bringing the price of a complete Amiga system to US$1,595 (). Before the release of the Amiga 500 and Amiga 2000 models in 1987, the A1000 was marketed as simply the Amiga, although the model number was there from the beginning, as the original box indicates. In the US, the A1000 was marketed as The Amiga from Commodore, with the Commodore logo omitted from the case. The Commodore branding was retained for the international versions. Additionally, the Amiga 1000 was sold exclusively in computer stores in the US rather than the various non computer-dedicated department and toy stores through which the VIC-20 and Commodore 64 were retailed. These measures were an effort to avoid Commodore's "toy-store" computer image created during the Tramiel era. Along with the operating system, the machine came bundled with a version of AmigaBASIC developed by Microsoft and a speech synthesis library developed by Softvoice, Inc. Aftermarket upgrades Many A1000 owners remained attached to their machines long after newer models rendered the units technically obsolete, and it attracted numerous aftermarket upgrades. Many CPU upgrades that plugged into the Motorola 68000 socket functioned in the A1000. Additionally, a line of products called the Rejuvenator series allowed the use of newer chipsets in the A1000, and an Australian-designed replacement A1000 motherboard called The Phoenix utilized the same chipset as the A3000 and added an A2000-compatible video slot and on-board SCSI controller. Impact In 1994, as Commodore filed for bankruptcy, Byte magazine called the Amiga 1000 "the first multimedia computer... so far ahead of its time that almost nobody—including Commodore's marketing department—could fully articulate what it was all about". In 2006, PC World rated the Amiga 1000 as the 7th greatest PC of all time. In 2007, it was rated by the same magazine as the 37th best tech product of all time. Joe Pillow "Joe Pillow" was the name given on the ticket for the extra airline seat purchased to hold the first Amiga prototype while on the way to the January 1984 Consumer Electronics Show. The airlines required a name for the airline ticket and Joe Pillow was born. The engineers (RJ Mical and Dale Luck) who flew with the Amiga prototype (codenamed Lorraine) drew a happy face on the front of the pillowcase and even added a tie. Joe Pillow extended his fifteen minutes of fame when the Amiga went to production. All fifty-three Amiga team members who worked on the project signed the Amiga case. This included Joe Pillow and Jay Miner's dog Michy who each got to "sign" the case in their own unique way.

Asymptote

In analytic geometry, an asymptote () of a curve is a line such that the distance between the curve and the line approaches zero as one or both of the x or y coordinates tends to infinity. In projective geometry and related contexts, an asymptote of a curve is a line which is tangent to the curve at a point at infinity. The word asymptote is derived from the Greek ἀσύμπτωτος (asumptōtos) which means "not falling together", from ἀ priv. + σύν "together" + πτωτ-ός "fallen". The term was introduced by Apollonius of Perga in his work on conic sections, but in contrast to its modern meaning, he used it to mean any line that does not intersect the given curve. There are three kinds of asymptotes: horizontal, vertical and oblique. For curves given by the graph of a function , horizontal asymptotes are horizontal lines that the graph of the function approaches as x tends to Vertical asymptotes are vertical lines near which the function grows without bound. An oblique asymptote has a slope that is non-zero but finite, such that the graph of the function approaches it as x tends to More generally, one curve is a curvilinear asymptote of another (as opposed to a linear asymptote) if the distance between the two curves tends to zero as they tend to infinity, although the term asymptote by itself is usually reserved for linear asymptotes. Asymptotes convey information about the behavior of curves in the large, and determining the asymptotes of a function is an important step in sketching its graph. The study of asymptotes of functions, construed in a broad sense, forms a part of the subject of asymptotic analysis. Introduction The idea that a curve may come arbitrarily close to a line without actually becoming the same may seem to counter everyday experience. The representations of a line and a curve as marks on a piece of paper or as pixels on a computer screen have a positive width. So if they were to be extended far enough they would seem to merge, at least as far as the eye could discern. But these are physical representations of the corresponding mathematical entities; the line and the curve are idealized concepts whose width is 0 (see Line). Therefore, the understanding of the idea of an asymptote requires an effort of reason rather than experience. Consider the graph of the function shown in this section. The coordinates of the points on the curve are of the form where x is a number other than 0. For example, the graph contains the points (1, 1), (2, 0.5), (5, 0.2), (10, 0.1), ... As the values of become larger and larger, say 100, 1,000, 10,000 ..., putting them far to the right of the illustration, the corresponding values of , .01, .001, .0001, ..., become infinitesimal relative to the scale shown. But no matter how large becomes, its reciprocal is never 0, so the curve never actually touches the x-axis. Similarly, as the values of become smaller and smaller, say .01, .001, .0001, ..., making them infinitesimal relative to the scale shown, the corresponding values of , 100, 1,000, 10,000 ..., become larger and larger. So the curve extends farther and farther upward as it comes closer and closer to the y-axis. Thus, both the x and y-axis are asymptotes of the curve. These ideas are part of the basis of concept of a limit in mathematics, and this connection is explained more fully below. Asymptotes of functions The asymptotes most commonly encountered in the study of calculus are of curves of the form . These can be computed using limits and classified into horizontal, vertical and oblique asymptotes depending on their orientation. Horizontal asymptotes are horizontal lines that the graph of the function approaches as x tends to +∞ or −∞. As the name indicates they are parallel to the x-axis. Vertical asymptotes are vertical lines (perpendicular to the x-axis) near which the function grows without bound. Oblique asymptotes are diagonal lines such that the difference between the curve and the line approaches 0 as x tends to +∞ or −∞. Vertical asymptotes The line x = a is a vertical asymptote of the graph of the function if at least one of the following statements is true: where is the limit as x approaches the value a from the left (from lesser values), and is the limit as x approaches a from the right. For example, if ƒ(x) = x/(x–1), the numerator approaches 1 and the denominator approaches 0 as x approaches 1. So and the curve has a vertical asymptote x = 1. The function ƒ(x) may or may not be defined at a, and its precise value at the point x = a does not affect the asymptote. For example, for the function has a limit of +∞ as , ƒ(x) has the vertical asymptote , even though ƒ(0) = 5. The graph of this function does intersect the vertical asymptote once, at (0, 5). It is impossible for the graph of a function to intersect a vertical asymptote (or a vertical line in general) in more than one point. Moreover, if a function is continuous at each point where it is defined, it is impossible that its graph does intersect any vertical asymptote. A common example of a vertical asymptote is the case of a rational function at a point x such that the denominator is zero and the numerator is non-zero. If a function has a vertical asymptote, then it isn't necessarily true that the derivative of the function has a vertical asymptote at the same place. An example is at . This function has a vertical asymptote at because and . The derivative of is the function . For the sequence of points for that approaches both from the left and from the right, the values are constantly . Therefore, both one-sided limits of at can be neither nor . Hence doesn't have a vertical asymptote at . Horizontal asymptotes Horizontal asymptotes are horizontal lines that the graph of the function approaches as . The horizontal line y = c is a horizontal asymptote of the function y = ƒ(x) if or . In the first case, ƒ(x) has y = c as asymptote when x tends to , and in the second ƒ(x) has y = c as an asymptote as x tends to . For example, the arctangent function satisfies and So the line is a horizontal asymptote for the arctangent when x tends to , and is a horizontal asymptote for the arctangent when x tends to . Functions may lack horizontal asymptotes on either or both sides, or may have one horizontal asymptote that is the same in both directions. For example, the function has a horizontal asymptote at y = 0 when x tends both to and because, respectively, Other common functions that have one or two horizontal asymptotes include (that has an hyperbola as it graph), the Gaussian function the error function, and the logistic function. Oblique asymptotes When a linear asymptote is not parallel to the x- or y-axis, it is called an oblique asymptote or slant asymptote. A function ƒ(x) is asymptotic to the straight line (m ≠ 0) if In the first case the line is an oblique asymptote of ƒ(x) when x tends to +∞, and in the second case the line is an oblique asymptote of ƒ(x) when x tends to −∞. An example is ƒ(x) = x + 1/x, which has the oblique asymptote y = x (that is m = 1, n = 0) as seen in the limits Elementary methods for identifying asymptotes The asymptotes of many elementary functions can be found without the explicit use of limits (although the derivations of such methods typically use limits). General computation of oblique asymptotes for functions The oblique asymptote, for the function f(x), will be given by the equation y = mx + n. The value for m is computed first and is given by where a is either or depending on the case being studied. It is good practice to treat the two cases separately. If this limit doesn't exist then there is no oblique asymptote in that direction. Having m then the value for n can be computed by where a should be the same value used before. If this limit fails to exist then there is no oblique asymptote in that direction, even should the limit defining m exist. Otherwise is the oblique asymptote of ƒ(x) as x tends to a. For example, the function has and then so that is the asymptote of ƒ(x) when x tends to +∞. The function has and then , which does not exist. So does not have an asymptote when x tends to +∞. Asymptotes for rational functions A rational function has at most one horizontal asymptote or oblique (slant) asymptote, and possibly many vertical asymptotes. The degree of the numerator and degree of the denominator determine whether or not there are any horizontal or oblique asymptotes. The cases are tabulated below, where deg(numerator) is the degree of the numerator, and deg(denominator) is the degree of the denominator. The vertical asymptotes occur only when the denominator is zero (If both the numerator and denominator are zero, the multiplicities of the zero are compared). For example, the following function has vertical asymptotes at x = 0, and x = 1, but not at x = 2. Oblique asymptotes of rational functions When the numerator of a rational function has degree exactly one greater than the denominator, the function has an oblique (slant) asymptote. The asymptote is the polynomial term after dividing the numerator and denominator. This phenomenon occurs because when dividing the fraction, there will be a linear term, and a remainder. For example, consider the function shown to the right. As the value of x increases, f approaches the asymptote y = x. This is because the other term, 1/(x+1), approaches 0. If the degree of the numerator is more than 1 larger than the degree of the denominator, and the denominator does not divide the numerator, there will be a nonzero remainder that goes to zero as x increases, but the quotient will not be linear, and the function does not have an oblique asymptote. Transformations of known functions If a known function has an asymptote (such as y=0 for f(x)=ex), then the translations of it also have an asymptote. If x=a is a vertical asymptote of f(x), then x=a+h is a vertical asymptote of f(x-h) If y=c is a horizontal asymptote of f(x), then y=c+k is a horizontal asymptote of f(x)+k If a known function has an asymptote, then the scaling of the function also have an asymptote. If y=ax+b is an asymptote of f(x), then y=cax+cb is an asymptote of cf(x) For example, f(x)=ex-1+2 has horizontal asymptote y=0+2=2, and no vertical or oblique asymptotes. General definition Let be a parametric plane curve, in coordinates A(t) = (x(t),y(t)). Suppose that the curve tends to infinity, that is: A line ℓ is an asymptote of A if the distance from the point A(t) to ℓ tends to zero as t → b. From the definition, only open curves that have some infinite branch can have an asymptote. No closed curve can have an asymptote. For example, the upper right branch of the curve y = 1/x can be defined parametrically as x = t, y = 1/t (where t > 0). First, x → ∞ as t → ∞ and the distance from the curve to the x-axis is 1/t which approaches 0 as t → ∞. Therefore, the x-axis is an asymptote of the curve. Also, y → ∞ as t → 0 from the right, and the distance between the curve and the y-axis is t which approaches 0 as t → 0. So the y-axis is also an asymptote. A similar argument shows that the lower left branch of the curve also has the same two lines as asymptotes. Although the definition here uses a parameterization of the curve, the notion of asymptote does not depend on the parameterization. In fact, if the equation of the line is then the distance from the point A(t) = (x(t),y(t)) to the line is given by if γ(t) is a change of parameterization then the distance becomes which tends to zero simultaneously as the previous expression. An important case is when the curve is the graph of a real function (a function of one real variable and returning real values). The graph of the function y = ƒ(x) is the set of points of the plane with coordinates (x,ƒ(x)). For this, a parameterization is This parameterization is to be considered over the open intervals (a,b), where a can be −∞ and b can be +∞. An asymptote can be either vertical or non-vertical (oblique or horizontal). In the first case its equation is x = c, for some real number c. The non-vertical case has equation , where m and are real numbers. All three types of asymptotes can be present at the same time in specific examples. Unlike asymptotes for curves that are graphs of functions, a general curve may have more than two non-vertical asymptotes, and may cross its vertical asymptotes more than once. Curvilinear asymptotes Let be a parametric plane curve, in coordinates A(t) = (x(t),y(t)), and B be another (unparameterized) curve. Suppose, as before, that the curve A tends to infinity. The curve B is a curvilinear asymptote of A if the shortest distance from the point A(t) to a point on B tends to zero as t → b. Sometimes B is simply referred to as an asymptote of A, when there is no risk of confusion with linear asymptotes. For example, the function has a curvilinear asymptote , which is known as a parabolic asymptote because it is a parabola rather than a straight line. Asymptotes and curve sketching Asymptotes are used in procedures of curve sketching. An asymptote serves as a guide line to show the behavior of the curve towards infinity. In order to get better approximations of the curve, curvilinear asymptotes have also been used although the term asymptotic curve seems to be preferred. Algebraic curves The asymptotes of an algebraic curve in the affine plane are the lines that are tangent to the projectivized curve through a point at infinity. For example, one may identify the asymptotes to the unit hyperbola in this manner. Asymptotes are often considered only for real curves, although they also make sense when defined in this way for curves over an arbitrary field. A plane curve of degree n intersects its asymptote at most at n−2 other points, by Bézout's theorem, as the intersection at infinity is of multiplicity at least two. For a conic, there are a pair of lines that do not intersect the conic at any complex point: these are the two asymptotes of the conic. A plane algebraic curve is defined by an equation of the form P(x,y) = 0 where P is a polynomial of degree n where Pk is homogeneous of degree k. Vanishing of the linear factors of the highest degree term Pn defines the asymptotes of the curve: setting , if , then the line is an asymptote if and are not both zero. If and , there is no asymptote, but the curve has a branch that looks like a branch of parabola. Such a branch is called a , even when it does not have any parabola that is a curvilinear asymptote. If the curve has a singular point at infinity which may have several asymptotes or parabolic branches. Over the complex numbers, Pn splits into linear factors, each of which defines an asymptote (or several for multiple factors). Over the reals, Pn splits in factors that are linear or quadratic factors. Only the linear factors correspond to infinite (real) branches of the curve, but if a linear factor has multiplicity greater than one, the curve may have several asymptotes or parabolic branches. It may also occur that such a multiple linear factor corresponds to two complex conjugate branches, and does not corresponds to any infinite branch of the real curve. For example, the curve has no real points outside the square , but its highest order term gives the linear factor x with multiplicity 4, leading to the unique asymptote x=0. Asymptotic cone The hyperbola has the two asymptotes The equation for the union of these two lines is Similarly, the hyperboloid is said to have the asymptotic cone The distance between the hyperboloid and cone approaches 0 as the distance from the origin approaches infinity. More generally, consider a surface that has an implicit equation where the are homogeneous polynomials of degree and . Then the equation defines a cone which is centered at the origin. It is called an asymptotic cone, because the distance to the cone of a point of the surface tends to zero when the point on the surface tends to infinity.

Andrew S. Tanenbaum

Andrew Stuart Tanenbaum (born March 16, 1944), sometimes referred to by the handle ast, is an American-Dutch computer scientist and professor emeritus of computer science at the Vrije Universiteit Amsterdam in the Netherlands. He is best known as the author of MINIX, a free Unix-like operating system for teaching purposes, and for his computer science textbooks, regarded as standard texts in the field. He regards his teaching job as his most important work. Since 2004 he has operated Electoral-vote.com, a website dedicated to analysis of polling data in federal elections in the United States. Biography Tanenbaum was born in New York City and grew up in suburban White Plains, New York. He is Jewish. His paternal grandfather was born in Khorostkiv in the Austro-Hungarian empire. He received his Bachelor of Science degree in physics from MIT in 1965 and his Ph.D. degree in astrophysics from the University of California, Berkeley in 1971. Tanenbaum also served as a lobbyist for the Sierra Club. He moved to the Netherlands to live with his wife, who is Dutch, but he retains his United States citizenship. He teaches courses about Computer Organization and Operating Systems and supervises the work of Ph.D. candidates at the VU University Amsterdam. On 9 July 2014, he announced his retirement. Teaching Books Tanenbaum is well recognized for his textbooks on computer science. They include: Structured Computer Organization (1976) Computer Networks, co-authored with David J. Wetherall and Nickolas Feamster (1981) Operating Systems: Design and Implementation, co-authored with Albert Woodhull (1987) Modern Operating Systems (1992) Distributed Operating Systems (1994) Distributed Systems: Principles and Paradigms, co-authored with Maarten van Steen (2001) His book, Operating Systems: Design and Implementation and MINIX were Linus Torvalds' inspiration for the Linux kernel. In his autobiography Just for Fun, Torvalds describes it as "the book that launched me to new heights". His books have been translated into many languages including Arabic, Basque, Bulgarian, Chinese, Dutch, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Korean, Macedonian, Mexican Spanish, Persian, Polish, Portuguese, Romanian, Russian, Serbian, and Spanish. They have appeared in over 175 editions and are used at universities around the world. Doctoral students Tanenbaum has had a number of Ph.D. students who themselves have gone on to become widely known computer science researchers. These include: Henri Bal, professor at the Vrije Universiteit in Amsterdam Frans Kaashoek, professor at MIT Sape Mullender, researcher at Bell Labs Robbert van Renesse, professor at Cornell University Leendert van Doorn, distinguished engineer at the Microsoft Corporation Werner Vogels, Chief Technology Officer at Amazon.com Dean of the Advanced School for Computing and Imaging In the early 1990s, the Dutch government began setting up a number of thematically oriented research schools that spanned multiple universities. These schools were intended to bring professors and Ph.D. students from different Dutch (and later, foreign) universities together to help them cooperate and enhance their research. Tanenbaum was one of the cofounders and first Dean of the Advanced School for Computing and Imaging (ASCI). This school initially consisted of nearly 200 faculty members and Ph.D. students from the Vrije Universiteit, University of Amsterdam, Delft University of Technology, and Leiden University. They were especially working on problems in advanced computer systems such as parallel computing and image analysis and processing. Tanenbaum remained dean for 12 years, until 2005, when he was awarded an Academy Professorship by the Royal Netherlands Academy of Arts and Sciences, at which time he became a full-time research professor. ASCI has since grown to include researchers from nearly a dozen universities in The Netherlands, Belgium, and France. ASCI offers Ph.D. level courses, has an annual conference, and runs various workshops every year. Projects Amsterdam Compiler Kit The Amsterdam Compiler Kit is a toolkit for producing portable compilers. It was started sometime before 1981 and Andrew Tanenbaum was the architect from the start until version 5.5. MINIX In 1987, Tanenbaum wrote a clone of UNIX, called MINIX (MINi-unIX), for the IBM PC. It was targeted at students and others who wanted to learn how an operating system worked. Consequently, he wrote a book that listed the source code in an appendix and described it in detail in the text. The source code itself was available on a set of floppy disks. Within three months, a Usenet newsgroup, comp.os.minix, had sprung up with over 40,000 subscribers discussing and improving the system. One of these subscribers was a Finnish student named Linus Torvalds, who began adding new features to MINIX and tailoring it to his own needs. On October 5, 1991, Torvalds announced his own (POSIX-like) kernel, called Linux, which originally used the MINIX file system but is not based on MINIX code. Although MINIX and Linux have diverged, MINIX continues to be developed, now as a production system as well as an educational one. The focus is on building a highly modular, reliable, and secure operating system. The system is based on a microkernel, with only 5000 lines of code running in kernel mode. The rest of the operating system runs as a number of independent processes in user mode, including processes for the file system, process manager, and each device driver. The system continuously monitors each of these processes, and when a failure is detected is often capable of automatically replacing the failed process without a reboot, without disturbing running programs, and without the user even noticing. MINIX 3, as the current version is called, is available under the BSD license for free. Research projects Tanenbaum has also been involved in numerous other research projects in the areas of operating systems, distributed systems, and ubiquitous computing, often as supervisor of Ph.D. students or a postdoctoral researcher. These projects include: Amoeba Globe Mansion Orca Paramecium RFID Guardian Turtle F2F Electoral-vote.com In 2004, Tanenbaum created Electoral-vote.com, a web site analyzing opinion polls for the 2004 U.S. Presidential Election, using them to project the outcome in the Electoral College. He stated that he created the site as an American who "knows first hand what the world thinks of America and it is not a pretty picture at the moment. I want people to think of America as the land of freedom and democracy, not the land of arrogance and blind revenge. I want to be proud of America again." The site provided a color-coded map, updated each day with projections for each state's electoral votes. Through most of the campaign period Tanenbaum kept his identity secret, referring to himself as "the Votemaster" and acknowledging only that he personally preferred John Kerry. Mentioning that he supported the Democrats, he revealed his identity on November 1, 2004, the day before the election, and also stating his reasons and qualifications for running the website. Through the site he also covered the 2006 midterm elections, correctly predicting the winner of all 33 Senate races that year. For the 2008 elections, he got every state right except for Indiana, which he said McCain would win by 2% (Obama won by 1%) and Missouri, which he said was too close to call (McCain won by 0.1%). He correctly predicted all the winners in the Senate except for Minnesota, where he predicted a 1% win by Norm Coleman over Al Franken. After 7 months of legal battling and recounts, Franken won by 312 votes (0.01%). In 2010, he correctly projected 35 out of 37 Senate races in the Midterm elections on the website. The exceptions were Colorado and Nevada. Electoral-vote.com incorrectly predicted Hillary Clinton would win the 2016 United States presidential election. The website incorrectly predicted Clinton would win Wisconsin, Michigan, Pennsylvania, North Carolina, and Florida. Electoral-vote.com did not predict a winner for Nevada, which Clinton would win.

Ariane 5

Ariane 5 is a European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais (CSG) in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. A direct successor system, Ariane 6, is in development. The system was designed as an expendable launch system by the Centre national d'études spatiales (CNES), the French government's space agency, in close cooperation with Germany and other European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it is classified as part of the Ariane rocket family. Airbus Defence and Space is the prime contractor for the vehicles, leading a multi-country consortium of other European contractors. ESA originally designed Ariane 5 to launch the Hermes spaceplane, and thus it is rated for human space launches. Since its first launch, Ariane 5 has been refined in successive versions: "G", "G+", "GS", "ECA", and most recently, "ES". The system has a commonly used dual-launch capability, where up to two large geostationary belt communication satellites can be mounted using a SYLDA (Système de Lancement Double Ariane, "Ariane Double-Launch System") carrier system. Up to three, somewhat smaller, main satellites are possible depending on size using SPELTRA (Structure Porteuse Externe Lancement Triple Ariane, "Ariane Triple-Launch External Carrier Structure"). Up to eight secondary payloads, usually small experiment packages or minisatellites, can be carried with an ASAP (Ariane Structure for Auxiliary Payloads) platform. After the launch of 15 August 2020, Arianespace had already signed the contracts for the last eight Ariane 5 launches, left to launch before the transition to the new Ariane 6 launcher, according to Daniel Neuenschwander, director of space transportation at the ESA. Vehicle description Cryogenic main stage Ariane 5's cryogenic H173 main stage (H158 for Ariane 5G, G+, and GS) is called the EPC (Étage Principal Cryotechnique — Cryotechnic Main Stage). It consists of a diameter by high tank with two compartments, one for liquid oxygen and one for liquid hydrogen, and a Vulcain 2 engine at the base with a vacuum thrust of . The H173 EPC weighs about , including of propellant. After the main cryogenic stage runs out of fuel, it re-enters the atmosphere for an ocean splashdown. Solid boosters Attached to the sides are two P241 (P238 for Ariane 5G and G+) solid rocket boosters (SRBs or EAPs from the French Étages d'Accélération à Poudre), each weighing about full and delivering a thrust of about . They are fueled by a mix of ammonium perchlorate (68%) and aluminium fuel (18%) and HTPB (14%). They each burn for 130 seconds before being dropped into the ocean. The SRBs are usually allowed to sink to the bottom of the ocean, but, like the Space Shuttle Solid Rocket Boosters, they can be recovered with parachutes, and this has occasionally been done for post-flight analysis. Unlike Space Shuttle SRBs, Ariane 5 boosters are not reused. The most recent attempt was for the first Ariane 5 ECA mission in 2009. One of the two boosters was successfully recovered and returned to the Guiana Space Center for analysis. Prior to that mission, the last such recovery and testing was done in 2003. The French M51 submarine-launched ballistic missile (SLBM) shares a substantial amount of technology with these boosters. In February 2000, the suspected nose cone of an Ariane 5 booster washed ashore on the South Texas coast, and was recovered by beachcombers before the government could get to it. Second stage The second stage is on top of the main stage and below the payload. The original Ariane — Ariane 5G — used the EPS (Étage à Propergols Stockables — Storable Propellant Stage), which was fueled by monomethylhydrazine (MMH) and nitrogen tetroxide, containing of storable propellant. The EPS was subsequently improved for use on the Ariane 5G+, GS, and ES. The EPS upper stage is capable of multiple ignitions, first demonstrated during flight V26 which was launched on 5 October 2007. This was purely to test the engine, and occurred after the payloads had been deployed. The first operational use of restart capability as part of a mission came on 9 March 2008, when two burns were made to deploy the first Automated Transfer Vehicle (ATV) into a circular parking orbit, followed by a third burn after ATV deployment to de-orbit the stage. This procedure was repeated for all subsequent ATV flights. Ariane 5ECA uses the ESC (Étage Supérieur Cryotechnique — Cryogenic Upper Stage), which is fueled by liquid hydrogen and liquid oxygen. The ESC uses the HM7B engine previously used in the Ariane 4 third stage. The propellent load of 14.7 tonne allows the engine to burn for 945 seconds while providing 6.5 tonne of thrust, The ESC provides roll control during powered flight and full attitude control during payload separation using hydrogen gas thrusters. Oxygen gas thrusters allow longitudinal acceleration after engine cutoff. The flight assembly includes the Vehicle Equipment Bay, with flight electronics for the entire rocket, and the payload interface and structural support. Fairing The payload and all upper stages are covered at launch by a fairing for aerodynamic stability and protection from heating during supersonic flight and acoustic loads. It is jettisoned once sufficient altitude has been reached, typically above . It is made by Ruag Space and since flight VA-238 it is composed of 4 panels. Variants Launch system status: Launch pricing and market competition , the Ariane 5 commercial launch price for launching a "midsize satellite in the lower position" was approximately €50 million, competing for commercial launches in an increasingly competitive market. The heavier satellite is launched in the upper position on a typical dual-satellite Ariane 5 launch and is priced higher than the lower satellite, on the order of €90 million . Total launch price of an Ariane 5 – which can transport up to two satellites to space, one in the "upper" and one in the "lower" positions – was around €150 million as of January 2015. Cancelled plans for future developments Ariane 5 ME The Ariane 5 ME (Mid-life Evolution) was in development into early 2015, and was seen as a stopgap between Ariane 5ECA/Ariane 5ES and the new Ariane 6. With first flight planned for 2018, it would have become ESA's principal launcher until the arrival of the new Ariane 6 version. ESA halted funding for the development of Ariane 5ME in late 2014 to prioritize development of Ariane 6. The Ariane 5ME was to use a new upper stage, with increased propellant volume, powered by the new Vinci engine. Unlike the HM-7B engine, it was to be able to restart several times, allowing for complex orbital maneuvers such as insertion of two satellites into different orbits, direct insertion into geosynchronous orbit, planetary exploration missions, and guaranteed upper stage deorbiting or insertion into graveyard orbit. The launcher was also to include a lengthened fairing up to and a new dual launch system to accommodate larger satellites. Compared to an Ariane 5ECA model, the payload to GTO was to increase by 15% to and the cost-per-kilogram of each launch is projected to decline by 20%. Development Originally known as the Ariane 5ECB, Ariane 5ME was to have its first flight in 2006. However, the failure of the first ECA flight in 2002, combined with a deteriorating satellite industry, caused ESA to cancel development in 2003. Development of the Vinci engine continued, though at a lower pace. The ESA Council of Ministers agreed to fund development of the new upper stage in November 2008. In 2009, EADS Astrium was awarded a €200 million contract, and on 10 April 2012 received another €112 million contract to continue development of the Ariane 5ME with total development effort expected to cost €1 billion. On 21 November 2012, ESA agreed to continue with the Ariane 5ME to meet the challenge of lower priced competitors. It was agreed the Vinci upper stage would also be used as the second stage of a new Ariane 6, and further commonality would be sought. Ariane 5ME qualification flight was scheduled for mid-2018, followed by gradual introduction into service. On 2 December 2014, ESA decided to stop funding the development of Ariane 5ME and instead focus on Ariane 6, which was expected to have a lower cost per launch and allow more flexibility in the payloads (using two or four P120C solid boosters depending on total payload mass). Solid propellant stage Work on the Ariane 5 EAP motors has been continued in the Vega programme. The Vega 1st stage engine – the P80 engine – is a shorter derivation of the EAP. The P80 booster casing is made of filament wound graphite epoxy, much lighter than the current stainless steel casing. A new composite steerable nozzle has been developed while new thermal insulation material and a narrower throat improve the expansion ratio and subsequently the overall performance. Additionally, the nozzle now has electromechanical actuators which have replaced the heavier hydraulic ones used for thrust vector control. These developments will probably later make their way back into the Ariane programme. The incorporation of the ESC-B with the improvements to the solid motor casing and an uprated Vulcain engine would deliver to LEO. This would be developed for any lunar missions but the performance of such a design may not be possible if the higher Max-Q for the launch of this launch vehicle poses a constraint on the mass delivered to orbit. Ariane 6 The design brief of the next generation launch vehicle Ariane 6 called for a lower-cost and smaller launch vehicle capable of launching a single satellite of up to to GTO. However, after several permutations the finalized design was nearly identical in performance to the Ariane 5, focusing instead on lowering fabrication costs and launch prices. Development is projected to cost €4 billion. In 2017, the ESA set July 16, 2020 as the deadline for the first flight. In 2020, its first test launch was set to not earlier than 2021., Ariane 6 was projected to be launched for about €70 million per flight or about half of the Ariane 5 current price. Notable launches Ariane 5's first test flight (Ariane 5 Flight 501) on 4 June 1996 failed, with the rocket self-destructing 37 seconds after launch because of a malfunction in the control software. A data conversion from 64-bit floating point value to 16-bit signed integer value to be stored in a variable representing horizontal bias caused a processor trap (operand error) because the floating point value was too large to be represented by a 16-bit signed integer. The software had been written for the Ariane 4 where efficiency considerations (the computer running the software had an 80% maximum workload requirement) led to four variables being protected with a handler while three others, including the horizontal bias variable, were left unprotected because it was thought that they were "physically limited or that there was a large margin of safety". The software, written in Ada, was included in the Ariane 5 through the reuse of an entire Ariane 4 subsystem despite the fact that the particular software containing the bug, which was just a part of the subsystem, was not required by the Ariane 5 because it has a different preparation sequence than the Ariane 4. The second test flight (L502, on 30 October 1997) was a partial failure. The Vulcain nozzle caused a roll problem, leading to premature shutdown of the core stage. The upper stage operated successfully, but it could not reach the intended orbit. A subsequent test flight (L503, on 21 October 1998) proved successful and the first commercial launch (L504) occurred on 10 December 1999 with the launch of the XMM-Newton X-ray observatory satellite. Another partial failure occurred on 12 July 2001, with the delivery of two satellites into an incorrect orbit, at only half the height of the intended GTO. The ESA Artemis telecommunications satellite was able to reach its intended orbit on 31 January 2003, through the use of its experimental ion propulsion system. The next launch did not occur until 1 March 2002, when the Envisat environmental satellite successfully reached an orbit of above the Earth in the 11th launch. At , it was the heaviest single payload until the launch of the first ATV on 9 March 2008, at . The first launch of the ECA variant on 11 December 2002 ended in failure when a main booster problem caused the rocket to veer off-course, forcing its self-destruction three minutes into the flight. Its payload of two communications satellites (STENTOR and Hot Bird 7), valued at about €630 million, was lost in the Atlantic Ocean. The fault was determined to have been caused by a leak in coolant pipes allowing the nozzle to overheat. After this failure, Arianespace SA delayed the expected January 2003 launch for the Rosetta mission to 26 February 2004, but this was again delayed to early March 2004 due to a minor fault in the foam that protects the cryogenic tanks on the Ariane 5. As of June 2017, the failure of the first ECA launch was the last failure of an Ariane 5; since then, 82 consecutive launches have been successful, from April 2003 with the launch of INSAT-3A and Galaxy 12 satellites, to flight 240 in December 2017. On 27 September 2003, the last Ariane 5G boosted three satellites (including the first European lunar probe, SMART-1), in Flight 162. On 18 July 2004, an Ariane 5G+ boosted what was at the time the heaviest telecommunication satellite ever, Anik F2, weighing almost . The first successful launch of the Ariane 5ECA took place on 12 February 2005. The payload consisted of the XTAR-EUR military communications satellite, a 'SLOSHSAT' small scientific satellite and a MaqSat B2 payload simulator. The launch had been scheduled for October 2004, but additional testing and a military launch (of a Helios 2A observation satellite) delayed the attempt. On 11 August 2005, the first Ariane 5GS (featuring the Ariane 5ECA's improved solid motors) boosted Thaicom 4, the heaviest telecommunications satellite to date at , into orbit. On 16 November 2005, the third Ariane 5ECA launch (the second successful ECA launch) took place. It carried a dual payload consisting of Spaceway F2 for DirecTV and Telkom-2 for PT Telekomunikasi of Indonesia. This was the launch vehicle's heaviest dual payload to date, at more than . On 27 May 2006, an Ariane 5ECA launch vehicle set a new commercial payload lifting record of . The dual-payload consisted of the Thaicom 5 and Satmex 6 satellites. On 4 May 2007, the Ariane 5ECA set another new commercial record, lifting into transfer orbit the Astra 1L and Galaxy 17 communication satellites with a combined weight of , and a total payload weight of . This record was again broken by another Ariane 5ECA, launching the Skynet 5B and Star One C1 satellites, on 11 November 2007. The total payload weight for this launch was of . On 9 March 2008, the first Ariane 5ES-ATV was launched to deliver the first ATV called Jules Verne to the International Space Station (ISS). The ATV was the heaviest payload ever launched by a European launch vehicle, providing supplies to the space station with necessary propellant, water, air and dry cargo. This was the first operational Ariane mission which involved an engine restart in the upper stage. The ES-ATV Aestus EPS upper stage was restartable while the ECA HM7-B engine was not. On 1 July 2009, an Ariane 5ECA launched TerreStar-1 (now EchoStar T1), which was then, at , the largest and most massive commercial telecommunication satellite ever built at that time until being overtaken by Telstar 19 Vantage, at , launched aboard Falcon 9. The satellite was launched into a lower-energy orbit than a usual GTO, with its initial apogee at roughly . On 28 October 2010, an Ariane 5ECA launched Eutelsat's W3B (part of its W Series of satellites) and Broadcasting Satellite System Corporation (B-SAT)'s BSAT-3b satellites into orbit. But the W3B satellite failed to operate shortly after the successful launch and was written off as a total loss due to an oxidizer leak in the satellite's main propulsion system. The BSAT-3b satellite, however, is operating normally. The VA253 launch on 15 August 2020 introduced two small changes that increased lift capacity by about ; these were a lighter avionics and guidance-equipment bay, and modified pressure vents on the payload fairing, which were required for the subsequent launch of the James Webb Space Telescope. It also debuted a location system using Galileo navigation satellites. On 25 December 2021, VA256 launched the James Webb Space Telescope towards a Sun–Earth L2 halo orbit. The precision of trajectory following launch led to fuel savings credited with potentially doubling the lifetime of the telescope by leaving more hydrazine propellant on-board for station-keeping than was expected. According to Rudiger Albat, the program manager for Ariane 5, efforts had been made to select components for this flight that had performed especially well during pre-flight testing, including "one of the best Vulcain engines that we've ever built." GTO payload weight records On 22 April 2011, the Ariane 5ECA flight VA-201 broke a commercial record, lifting Yahsat 1A and Intelsat New Dawn with a total payload weight of to transfer orbit. This record was later broken again during the launch of Ariane 5ECA flight VA-208 on 2 August 2012, lifting a total of into the planned geosynchronous transfer orbit, which was broken again 6 months later on flight VA-212 with sent towards geosynchronous transfer orbit. In June 2016, the GTO record was raised to , on the first rocket in history that carried a satellite dedicated to financial institutions. The payload record was pushed a further , up to on 24 August 2016 with the launch of Intelsat 33e and Intelsat 36. On 1 June 2017, the payload record was broken again to carrying ViaSat-2 and Eutelsat-172B. In 2021 VA-255 put 11,210 kg into GTO. VA241 anomaly On 25 January 2018, an Ariane 5ECA launched SES-14 and Al Yah 3 satellites. About 9 minutes and 28 seconds after launch, a telemetry loss occurred between the launch vehicle and the ground controllers. It was later confirmed, about 1 hour and 20 minutes after launch, that both satellites were successfully separated from the upper stage and were in contact with their respective ground controllers, but that their orbital inclinations were incorrect as the guidance systems might have been compromised. Therefore, both satellites conducted orbital procedures, extending commissioning time. SES-14 needed about 8 weeks longer than planned commissioning time, meaning that entry into service was reported early September instead of July. Nevertheless, SES-14 is still expected to be able to meet the designed lifetime. This satellite was originally to be launched with more propellant reserve on a Falcon 9 launch vehicle since the Falcon 9, in this specific case, was intended to deploy this satellite into a high inclination orbit that would require more work from the satellite to reach its final geostationary orbit. The Al Yah 3 was also confirmed healthy after more than 12 hours without further statement, and like SES-14, Al Yah 3's maneuvering plan was also revised to still fulfill the original mission. As of 16 February 2018, Al Yah 3 was approaching the intended geostationary orbit, after series of recovery maneuvers had been performed. The investigation showed that invalid inertial units' azimuth value had sent the vehicle 17° off course but to the intended altitude, they had been programmed for the standard geostationary transfer orbit of 90° when the payloads were intended to be 70° for this supersynchronous transfer orbit mission, 20° off norme. This mission anomaly marked the end of 82nd consecutive success streak since 2003. Launch history Launch statistics Ariane 5 launch vehicles have accumulated 111 launches since 1996, 106 of which were successful, yielding a success rate. Between April 2003 and December 2017, Ariane 5 flew 83 consecutive missions without failure, but the launch vehicle suffered a partial failure in January 2018.

Arianespace

Arianespace SA is a French company founded in 1980 as the world's first commercial launch service provider. It undertakes the operation and marketing of the Ariane programme. The company offers a number of different launch vehicles: the heavy-lift Ariane 5 for dual launches to geostationary transfer orbit, the Soyuz-2 as a medium-lift alternative, and the solid-fueled Vega for lighter payloads. , Arianespace had launched more than 850 satellites in 287 launches over 41 years. The first commercial flight managed by the new entity was Spacenet F1 launched on 23 May 1984. Arianespace uses the Guiana Space Centre in French Guiana as its main launch site. Through shareholding in Starsem, it can also offer commercial Soyuz launches from the Baikonur spaceport in Kazakhstan. It has its headquarters in Évry-Courcouronnes, Essonne, France. History The formation of Arianespace SA is closely associated with the desire of several European nations to pursue joint collaboration in the field of space exploration and the formation of a pan-national organisation, the European Space Agency (ESA), to oversee such undertaking during 1973. Prior to the ESA's formation, France had been lobbying for the development of a new European expendable launch system to serve as a replacement for the Europa rocket. Accordingly, one of the first programmes launched by the ESA was the Ariane heavy launcher. The express purpose of this launcher was to facilitate the delivery of commercial satellites into geosynchronous orbit. France was the largest stakeholder in the Ariane development programme. French aerospace manufacturer Aérospatiale served as the prime contractor and held responsibility for performing the integration of all sections of the vehicle, while French engine manufacturer Société Européenne de Propulsion (SEP) provided both the first and second stage engines (the third stage engines were produced by Air Liquide and German aerospace manufacturer MBB). Other major companies involved included the French electronics firm Matra, Swedish manufacturer Volvo, and German aircraft producer Dornier Flugzeugwerke. Development of the third stage was a major focus point for the project - prior to Ariane, only the United States had ever flown a launcher that utilised hydrogen-powered upper stages. Immediately following the successful first test launch of an Ariane 1 on 24 December 1979, the French space agency Centre national d'études spatiales (CNES) and the ESA created a new company, Arianespace, for the purpose of promoting, marketing, and managing Ariane operations. According to Arianespace, at the time of its establishment, it was the world's first launch services company. Following a further three test launches, the first commercial launch took place on 10 September 1982, which ended in failure as a result of a turbopump having failed in the third stage. The six remaining flights of the Ariane 1 were successful, with the final flight occurring during February 1986. As a result of these repeated successes, orders for the Ariane launcher quickly mounted up; by early 1984, a total of 27 satellites had been booked to use Ariane, which was estimated to be half of the world's market at that time. As a result of the commercial success, after the tenth Ariane mission was flown, the ESA formally transferred responsibility for Ariane over to Arianespace. By early 1986, the Ariane 1, along with its Ariane 2 and Ariane 3 derivates, were the dominant launcher on the world market. The Ariane 2 and Ariane 3 were short-lived platforms while the more extensive Ariane 4 was being developed; it was a considerably larger and more flexible launcher that the earlier members of its family, having been intended from the onset to compete with the upper end of launchers worldwide. In comparison, while the Ariane 1 had a typical weight of 207 tonnes and could launch payloads of up to 1.7 tonnes into orbit; the larger Ariane 4 had a typical weight of 470 tonnes and could orbit payloads of up to 4.2 tonnes. Despite this, the Ariane 4 was actually 15 per cent smaller than the Ariane 3. On 15 June 1988, the first successful launch of the Ariane 4 was conducted. This maiden flight was considered a success, having placed multiple satellites into orbit. For the V50 launch onwards, an improved third stage, known as the H10+, was adopted for the Ariane 4, which raised the rocket's overall payload capacity by 110 kg and increased its burn time by 20 seconds. Even prior to the first flight of the Ariane 4 in 1988, development of a successor, designated as the Ariane 5, had already commenced. In January 1985, the Ariane 5 was officially adopted as an ESA programme, and began an eleven-year development and test program to the first launch in 1996. It lacked the high levels of commonality that the Ariane 4 had with its predecessors, and had been designed not only for launching heavier payloads of up to 5.2 tonnes and at a 20 per cent cost reduction over the Ariane 4, but for a higher margin of safety due to the fact that the Ariane 5 was designed to conduct crewed space launches as well, being intended to transport astronauts using the proposed Hermes space vehicle. Development of the Ariane 5 was not without controversy as some ESA members considered the mature Ariane 4 platform to be more suited for meeting established needs for such launchers; it was reportedly for this reason that Britain chose not to participate in the Ariane 5 programme. For several years, Ariane 4 and Ariane 5 launchers were operated interchangeably; however, it was eventually decided to terminate all Ariane 4 operations in favour of concentrating on the newer Ariane 5. During the mid-1990s, French firms Aérospatiale and SEP, along with Italian firm Bombrini-Parodi-Delfino (BPD), held discussions on the development of a proposed Ariane Complementary Launcher (ACL). Simultaneously, Italy championed the concept of a new solid-propellant satellite launcher, referred to as Vega. During March 2003, contracts for Vega's development were signed by the ESA and CNES; Italy provided 65 per cent of funding while six additional nations contributed the remainder. In May 2004, it was reported that a contract was signed between commercial operator Arianespace and prime contractor ELV to perform vehicle integration at Kourou, French Guiana. On 13 February 2012, the first launch of the Vega took place; it was reported as being an "apparently perfect flight". Since entering commercial service, Arianespace markets Vega as a launch system tailored for missions to polar and sun-synchronous orbits. During 2002, the ESA announced the Arianespace Soyuz programme in cooperation with Russia; a launch site for Soyuz was constructed as the Guiana Space Centre, while the Soyuz launch vehicle was modified for use at the site. On 4 February 2005, both funding and final approval for the initiative were granted. Arianespace had offered launch services on the modified Soyuz ST-B to its clients. On 21 October 2011, Arianespace launched the first Soyuz rocket ever from outside former Soviet territory. The payload consisted of two Galileo navigation satellites. Since 2011, Arianespace has ordered a total of 23 Soyuz rockets, enough to cover its needs until 2019 at a pace of three to four launches per year. On 21 January 2019, ArianeGroup and Arianespace announced that it had signed a one-year contract with the ESA to study and prepare for a mission to the Moon to mine regolith. In 2020, Arianespace suspended operations for nearly two months due to the COVID-19 pandemic. Operations were suspended on 18 March and are, as of 29 April, expected to resume on 11 May. The return to operations will observe a number of new health and safety guidelines including social distancing in the workplace. Company and infrastructure Arianespace "is the marketing and sales organization for the European space industry and various component suppliers." The primary shareholders of Arianespace are its suppliers, in various European nations. Arianespace had 24 shareholders in 2008, 21 in 2014, and just 17 . In 2015, Arianespace shareholding was restructured due to the creation of Airbus Safran Launchers (later renamed ArianeGroup), which is tasked with developing and manufacturing the Ariane 6 carrier rocket. Industrial groups Airbus and Safran pooled their shares along with the French government's CNES stake to form a partnership company holding just under 74% of Arianespace shares, while the remaining 26% is spread across suppliers in nine countries including further Airbus subsidiaries. Corporate management , the Arianespace management team was: Regional offices Subsidiaries Arianespace inc. (U.S. Subsidiary) Arianespace Singapore PTE LTD. (Asian Subsidiary) Starsem S.A. (European-Russian Soyuz commercialization) Competition and pricing By 2004, Arianespace reportedly held more than 50% of the world market for boosting satellites to geostationary transfer orbit (GTO). During the 2010s, the disruptive force represented by the new sector entrant SpaceX forced Arianespace to cut back on its workforce and focus on cost-cutting to decrease costs to remain competitive against the new low-cost entrant in the launch sector. In the midst of pricing pressure from such companies, during November 2013, Arianespace announced that it was enacting pricing flexibility for the "lighter satellites" that it carries to Geostationary orbits aboard its Ariane 5. According to Arianespace's managing director: "It's quite clear there's a very significant challenge coming from SpaceX (...) therefore things have to change (...) and the whole European industry is being restructured, consolidated, rationalised and streamlined." During early 2014, Arianespace was considering requesting additional subsidies from European governments to face competition from SpaceX and unfavorable changes in the Euro-Dollar exchange rate. The company had halved subsidy support by €100m per year since 2002 but the fall in the value of the US Dollar meant Arianespace was losing €60m per year due to currency fluctuations on launch contracts. SpaceX had reportedly begun to take market share from Arianespace, Eutelsat CEO Michel de Rosen, a major customer of Arianespace, stated that: "Each year that passes will see SpaceX advance, gain market share and further reduce its costs through economies of scale." By September 2014, Arianespace had reportedly to sign four additional contracts for lower slots on an Ariane 5 SYLDA dispenser for satellites that otherwise could be flown on a SpaceX launch vehicle; this was claimed to have been allowed via cost reductions; it had signed a total of 11 contracts by that point, while two additional ones that were under advanced negotiations. At the time, Arianespace has a backlog of launches worth billion with 38 satellites to be launched on Ariane 5, 7 on Soyuz and 9 on Vega, claiming 60% of the global satellite launch market. However, since 2017, Arianespace's market share has been passed by SpaceX in commercial launches. Launch vehicles Currently Arianespace operates 3 launch vehicles, including two versions of Ariane 5: Additionally Arianespace offers optional back-up launch service on H-IIA through Launch Services Alliance. Ariane launch vehicles Since the first launch in 1979, there have been several versions of the Ariane launch vehicle: Ariane 1, first successful launch on December 24, 1979 Ariane 2, first successful launch on November 20, 1987 (the first launch on May 30, 1986, failed) Ariane 3, first successful launch on August 4, 1984 Ariane 4, first successful launch on June 15, 1988 Ariane 5, first successful launch on October 30, 1997 (the first launch on June 4, 1996, failed). Ariane 6, in development. It would have a similar payload capacity to that of Ariane 5 but considerably lower costs. Tentatively, its first flight is planned for 2022. Ariane Next, in early development. It will be a partially reusable launcher that should succeed Ariane 6 from the 2030s. The objective of this reusable launcher is to halve the launch costs.

Accumulator (computing)

In a computer's central processing unit (CPU), the accumulator is a register in which intermediate arithmetic logic unit results are stored. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to main memory, perhaps only to be read right back again for use in the next operation. Access to main memory is slower than access to a register like an accumulator because the technology used for the large main memory is slower (but cheaper) than that used for a register. Early electronic computer systems were often split into two groups, those with accumulators and those without. Modern computer systems often have multiple general-purpose registers that can operate as accumulators, and the term is no longer as common as it once was. However, to simplify their design, a number of special-purpose processors still use a single accumulator. Basic concept Mathematical operations often take place in a stepwise fashion, using the results from one operation as the input to the next. For instance, a manual calculation of a worker's weekly payroll might look something like: look up the number of hours worked from the employee's time card look up the pay rate for that employee from a table multiply the hours by the pay rate to get their basic weekly pay multiply their basic pay by a fixed percentage to account for income tax subtract that number from their basic pay to get their weekly pay after tax multiply that result by another fixed percentage to account for retirement plans subtract that number from their basic pay to get their weekly pay after all deductions A computer program carrying out the same task would follow the same basic sequence of operations, although the values being looked up would all be stored in computer memory. In early computers, the number of hours would likely be held on a punch card and the pay rate in some other form of memory, perhaps a magnetic drum. Once the multiplication is complete, the result needs to be placed somewhere. On a "drum machine" this would likely be back to the drum, an operation that takes considerable time. And then the very next operation has to read that value back in, which introduces another considerable delay. Accumulators dramatically improve performance in systems like these by providing a scratchpad area where the results of one operation can be fed to the next one for little or no performance penalty. In the example above, the basic weekly pay would be calculated and placed in the accumulator, which could then immediately be used by the income tax calculation. This removes one save and one read operation from the sequence, operations that generally took tens to hundreds of times as long as the multiplication itself. Accumulator machines An accumulator machine, also called a 1-operand machine, or a CPU with accumulator-based architecture, is a kind of CPU where, although it may have several registers, the CPU mostly stores the results of calculations in one special register, typically called "the accumulator". Almost all computers were accumulator machines with only the high-performance "supercomputers" having multiple registers. Then as mainframe systems gave way to microcomputers, accumulator architectures were again popular with the MOS 6502 being a notable example. Many 8-bit microcontrollers that are still popular as of 2014, such as the PICmicro and 8051, are accumulator-based machines. Modern CPUs are typically 2-operand or 3-operand machines. The additional operands specify which one of many general purpose registers (also called "general purpose accumulators") are used as the source and destination for calculations. These CPUs are not considered "accumulator machines". The characteristic which distinguishes one register as being the accumulator of a computer architecture is that the accumulator (if the architecture were to have one) would be used as an implicit operand for arithmetic instructions. For instance, a CPU might have an instruction like: ADD memaddress that adds the value read from memory location memaddress to the value in the accumulator, placing the result back in the accumulator. The accumulator is not identified in the instruction by a register number; it is implicit in the instruction and no other register can be specified in the instruction. Some architectures use a particular register as an accumulator in some instructions, but other instructions use register numbers for explicit operand specification. History of the computer accumulator Any system that uses a single "memory" to store the result of multiple operations can be considered an accumulator. J. Presper Eckert refers to even the earliest adding machines of Gottfried Leibniz and Blaise Pascal as accumulator-based systems. Percy Ludgate was the first to conceive a multiplier-accumulator (MAC) in his Analytical Machine of 1909. Historical convention dedicates a register to "the accumulator", an "arithmetic organ" that literally accumulates its number during a sequence of arithmetic operations: "The first part of our arithmetic organ ... should be a parallel storage organ which can receive a number and add it to the one already in it, which is also able to clear its contents and which can store what it contains. We will call such an organ an Accumulator. It is quite conventional in principle in past and present computing machines of the most varied types, e.g. desk multipliers, standard IBM counters, more modern relay machines, the ENIAC" (Goldstine and von Neumann, 1946; p. 98 in Bell and Newell 1971). Just a few of the instructions are, for example (with some modern interpretation): Clear accumulator and add number from memory location X Clear accumulator and subtract number from memory location X Add number copied from memory location X to the contents of the accumulator Subtract number copied from memory location X from the contents of the accumulator Clear accumulator and shift contents of register into accumulator No convention exists regarding the names for operations from registers to accumulator and from accumulator to registers. Tradition (e.g. Donald Knuth's (1973) hypothetical MIX computer), for example, uses two instructions called load accumulator from register/memory (e.g. "LDA r") and store accumulator to register/memory (e.g. "STA r"). Knuth's model has many other instructions as well. Notable accumulator-based computers The 1945 configuration of ENIAC had 20 accumulators, which could operate in parallel. Each one could store an eight decimal digit number and add to it (or subtract from it) a number it received. Most of IBM's early binary "scientific" computers, beginning with the vacuum tube IBM 701 in 1952, used a single 36-bit accumulator, along with a separate multiplier/quotient register to handle operations with longer results. The IBM 650, a decimal machine, had one 10 digit distributor and two ten-digit accumulators; the IBM 7070, a later, transistorized decimal machine had three accumulators. The IBM System/360, and Digital Equipment Corporation's PDP-6, had 16 general purpose registers, although the PDP-6 and its successor, the PDP-10, call them accumulators. The 12-bit PDP-8 was one of the first minicomputers to use accumulators, and inspired many later machines. The PDP-8 had but one accumulator. The HP 2100 and Data General Nova had 2 and 4 accumulators. The Nova was created when this follow-on to the PDP-8 was rejected in favor of what would become the PDP-11. The Nova provided four accumulators, AC0-AC3, although AC2 and AC3 could also be used to provide offset addresses, tending towards more generality of usage for the registers. The PDP-11 had 8 general purpose registers, along the lines of the System/360 and PDP-10; most later CISC and RISC machines provided multiple general purpose registers. Early 4-bit and 8-bit microprocessors such as the 4004, 8008 and numerous others, typically had single accumulators. The 8051 microcontroller has two, a primary accumulator and a secondary accumulator, where the second is used by instructions only when multiplying (MUL AB) or dividing (DIV AB); the former splits the 16-bit result between the two 8-bit accumulators, whereas the latter stores the quotient on the primary accumulator A and the remainder in the secondary accumulator B. As a direct descendant of the 8008, the 8080, and the 8086, the modern ubiquitous Intel x86 processors still uses the primary accumulator EAX and the secondary accumulator EDX for multiplication and division of large numbers. For instance, MUL ECX will multiply the 32-bit registers ECX and EAX and split the 64-bit result between EAX and EDX. However, MUL and DIV are special cases; other arithmetic-logical instructions (ADD, SUB, CMP, AND, OR, XOR, TEST) may specify any of the eight registers EAX, ECX, EDX, EBX, ESP, EBP, ESI, EDI as the accumulator (i.e. left operand and destination). This is also supported for multiply if the upper half of the result is not required. x86 is thus a fairly general register architecture, despite being based on an accumulator model. The 64-bit extension of x86, x86-64, has been further generalized to 16 instead of 8 general registers.

Abu Zubaydah

Abu Zubaydah ( ; , Abū Zubaydah; born March 12, 1971, as Zayn al-Abidin Muhammad Husayn) is a Saudi Arabian currently held by the U.S. in the Guantanamo Bay detention camp in Cuba. He is held under the authority of Authorization for Use of Military Force Against Terrorists (AUMF). Zubaydah was captured in Pakistan in March 2002 and has been in United States custody ever since, including four-and-a-half years in the secret prison network of the Central Intelligence Agency (CIA). He was transferred among prisons in various countries including a year in Poland, as part of a United States' extraordinary rendition program. During his time in CIA custody, Zubaydah was extensively interrogated; he was water-boarded 83 times and subjected to numerous other torture techniques including forced nudity, sleep deprivation, confinement in small dark boxes, deprivation of solid food, stress positions, and physical assaults. Videotapes of some of Zubaydah's interrogations are amongst those destroyed by the CIA in 2005. Zubaydah and ten other "high-value detainees" were transferred to Guantanamo in September 2006. He and other former CIA detainees are held in Camp 7, where conditions are the most isolating. At his Combatant Status Review Tribunal in 2007, Zubaydah said he was told that the CIA realized he was not significant. On July 24, 2014, the European Court of Human Rights (ECHR) ordered the Polish government to pay Zubaydah €100,000 in damages. It also awarded him €30,000 to cover his costs. Poland cooperated with the US, allowing the CIA to hold and torture Zubaydah on its territory in 2002–2003. Zubaydah said through his US lawyer that he would be donating the full €100,000 in damages to victims of torture. Joseph Margulies is a lawyer for Zubaydah. Biography and early activities According to his younger brother Hesham, they had eight siblings. Hesham remembers his older brother "as a happy-go-lucky guy, and something of a womanizer". Born in Saudi Arabia, Zubaydah moved to the West Bank as a teenager, where he joined in Palestinian demonstrations against the Israelis. Zubaydah is reported to have studied computer science in Mysore, India, prior to his travel to Afghanistan/Pakistan at the age of 20 in 1991. He joined the mujahideen in the Afghan civil war, perhaps serving under Mohamad Kamal Elzahabi. In 1992, Zubaydah was injured in a mortar shell blast, which left shrapnel in his head and caused severe memory loss, as well as the loss of the ability to speak for over one year. Zubaydah eventually became involved in the jihad training site known as the Khalden training camp, where he oversaw the flow of recruits and obtained passports and paperwork for men transferring out of Khalden. He may also have worked as an instructor there. Although originally described as an al-Qaeda training camp, this alleged connection, which has been used as justification for holding Zubaydah and others as enemy combatants, has come under scrutiny from multiple sources, and the camp may have shut its doors in 2001 in response to an ideological division with al-Qaeda. By 1999, the United States government was attempting to surveil Zubaydah. By March 2000, United States officials were reporting that Zubaydah was a "senior bin Laden official", the "former head of Egypt-based Islamic Jihad", a "trusted aide" to bin Laden with "growing power", who had "played a key role in the East Africa embassy attacks". Zubaydah was convicted in absentia in Jordan and sentenced to death by a Jordanian court for his role in plots to bomb U.S. and Israeli targets there. A senior Middle East security official said Zubaydah had directed the Jordanian cell and was part of "bin Laden's inner circle". In August 2001, the classified FBI report, "Bin Ladin Determined To Strike in US", said that the foiled millennium bomber, Ahmed Ressam, had confessed that Zubaydah had encouraged him to blow up the Los Angeles airport and facilitated his mission. The report said that Zubaydah was also planning his own attack on the U.S. However, when Ressam was tried in December 2001, federal prosecutors did not try to connect him to Zubaydah or refer to any of this supposed evidence in its case. After the trial, Ressam recanted his confession, saying he had been coerced into giving it. According to a psychological evaluation conducted upon his capture, Zubaydah allegedly served as Osama bin Laden's senior lieutenant and counter-intelligence officer (i.e. third or fourth highest-ranking member of al Qaeda), managed a network of training camps, was involved in every major terrorist operation carried out by al Qaeda (including the planning of 9/11), and was engaged in planning future terrorist attacks against U.S. interests. These statements were widely echoed by members of the Bush administration and other US officials. Zubaydah's perceived "value" as a detainee would later be used by President George W. Bush to justify the use of "enhanced interrogation techniques" and Zubaydah's detention in secret CIA prisons around the world. However, Zubaydah's connection to al Qaeda is now often said to have beenaccording to Rebecca Gordon writing about "The al Qaeda Leader Who Wasn't"a fictitious charge. Others have said instead that it is merely overstated, and in response to his habeas corpus petition, the U.S. Government stated in 2009 that it did not contend Zubaydah had any involvement with the 9/11 attacks, or that he had even been a member of al Qaeda, simply because they did not have to: "In simple terms, the issue in this habeas corpus action is Petitioner's conduct", rather than membership or inclination: "Petitioner's personal philosophy is not relevant except to the extent that it is reflected in his actions". Capture On March 28, 2002, CIA and FBI agents, in conjunction with Pakistani intelligence agency, raided several safe houses in Pakistan searching for Zubaydah. Zubaydah was apprehended from one of the targeted safe houses in Faisalabad, Pakistan. The Pakistani intelligence service had paid a small amount for a tip on his whereabouts. The United States paid far more to Pakistan for its assistance; a CIA source later said: "We paid $10 million for Zubaydah." During the raid, Zubaydah was shot in the thigh, the testicle, and the stomach with rounds from a Kalashnikov assault rifle. Not recognized at first, he was piled into a pickup truck along with other prisoners by the Pakistani forces, until a senior CIA officer identified him. He was taken by the Pakistanis to a Pakistani hospital nearby and treated for his wounds. The attending doctor told the CIA lead officer of the group which apprehended Zubaydah, that he had never before seen a patient survive such severe wounds. The CIA flew in a doctor from Johns Hopkins University to ensure Zubaydah would survive during transit out of Pakistan. His pocket litter supposedly contained two bank cards which showed that he had access to Saudi and Kuwaiti bank accounts; most al-Qaeda members used the preferred, untraceable hawala banking. According to James Risen: "It is not clear whether an investigation of the cards simply fell through the cracks, or whether they were ignored because no one wanted to know the answers about connections between al Qaeda and important figures in the Middle East – particularly in Saudi Arabia." One of Risen's sources chalks up the failure to investigate the cards to incompetence rather than foul play: "The cards were sent back to Washington and were never fully exploited. I think nobody ever looked at them because of incompetence." When Americans investigated the cards, Risen wrote that they worked with a Muslim financier with a questionable past, and with connections to the Afghan Taliban, al Qaeda, and Saudi intelligence. ... Saudi intelligence officials had seized all of the records related to the card from the Saudi financial institution in question; the records then disappeared. There was no longer any way to trace the money that had gone into the account. A search of the safehouse turned up Zubaydah's personal 10,000-page diaries, in which he recorded his thoughts as a young boy, old man, and at his current age. What appears to be multiple separate identities is how Zubaydah was piecing his memories together after his 1992 shrapnel head wound. As part of his therapy to regain his memories, he began recording the diary that detailed his life, emotions, and what people were telling him. He split information into categories, such as what he knew about himself and what people told him, and listed them under different names to distinguish one set from the other. This was later interpreted by some analysts reviewing the diary as symptoms of Dissociative Identity Disorder, which was disputed and said to be incorrect by some others. Zubaydah was handed to the CIA. Reports later alleged that he was transferred to secret CIA-operated prisons, known as black sites, in Pakistan, Thailand, Afghanistan, Poland, Northern Africa, and Diego Garcia. Historically, renditions of prisoners to countries which commit torture have been illegal. A memo written by John Yoo and signed by Jay Bybee of the Office of the Legal Counsel, DOJ, days before Zubaydah's capture, provided a legal opinion providing for CIA renditions of detainees to places such as Thailand. In March 2009, the U.S. Senate Intelligence Committee launched a year-long study on how the CIA operated the secret prisons, or black sites, around the world. Top U.S. officials approved torture techniques In the spring of 2002, immediately following the capture of Zubaydah, top Bush administration officials, Vice President Dick Cheney, Secretary of State Colin Powell, CIA Director George Tenet, National Security Adviser Condoleezza Rice, Secretary of Defense Donald Rumsfeld, and US Attorney General John Ashcroft discussed at length whether or not the CIA could legally use harsh techniques against him. Condoleezza Rice specifically mentioned the SERE program during the meeting, saying, "I recall being told that U.S. military personnel were subjected to training to certain physical and psychological interrogation techniques". In addition, in 2002 and 2003, the administration briefed several Democratic Congressional leaders on the proposed "enhanced interrogation techniques". These congressional leaders included Nancy Pelosi, the future Speaker of the House, and Representative Jane Harman. Congressional officials have stated that the attitude in the briefings ranged from "quiet acquiescence, if not downright support". The documents show that top U.S. officials were intimately involved in the discussion and approval of the harsher interrogation techniques used on Zubaydah. Condoleezza Rice ultimately told the CIA the harsher interrogation tactics were acceptable, and Dick Cheney stated, "I signed off on it; so did others." During the discussions, US Attorney General John Ashcroft is reported as saying, "Why are we talking about this in the White House? History will not judge this kindly." Torture drawings In December 2019, The New York Times published an article in partnership with the Pulitzer Center on Crisis Reporting which was based upon drawings made by Zubaydah, showing how he was tortured in "vivid and disturbing ways". The article includes some of the drawings as well as a link to a 61-page report titled "How America Tortures", and asserts that Zubaydah was never a member of Al Qaeda. In the article Zubaydah gives gruesome details of numerous types of torture including being locked up inside a small box called "the dog box" for "countless hours", which caused muscle contractions. "The very strong pain", he said, "made me scream unconsciously". According to the Senate Intelligence Committee report on CIA torture, over a single 20 day period, Zubaydah spent over 11 days locked in a "coffin size" box, and 29 hours in a box measuring 21 inches wide, 2 feet deep, and 2 feet high (). Interrogation of Zubaydah Zubaydah was interrogated by two separate interrogation teams: the first from the FBI and one from the CIA. Ali Soufan, one of the FBI interrogators, later testified in 2009 on these issues to the Senate Committee that was investigating detainee treatment. Soufan, who witnessed part of the CIA interrogation of Zubaydah, described his treatment under the CIA as torture. The International Committee of the Red Cross and others later reached the same conclusion. While in CIA custody, Zubaydah lost his left eye. Because of the urgency felt about the interrogation of Zubaydah, the CIA had consulted with the president about how to proceed. The General Counsel of the CIA asked for a legal opinion from the Office of Legal Counsel, Department of Justice about what was permissible during interrogation. August 2002 memo In early July 2002, the Associate General Counsel CTC/Legal Group started drafting a memo to the Attorney General requesting the approval of "aggressive" interrogation methods, which otherwise would be prohibited under the provisions of Section 2340-2340B, Title 18, United States Code, on Abu Zubaydah. This memo, drafted by Office of Legal Counsel, Jay Bybee and his assistant John Yoo, is also referred to as the first Torture Memo. Addressed to CIA acting General Counsel John A. Rizzo at his request, the purpose of the memo was to describe and authorize specific "enhanced interrogation techniques" to be used on Zubaydah. On July 26, 2002, Deputy Assistant Attorney General John Yoo informed the CIA that Attorney General John Ashcroft had approved waterboarding of Abu Zubaydah. Journalists including Jane Mayer, Joby Warrick and Peter Finn, and Alex Koppelman have reported the CIA was already using these harsh tactics before the memo authorizing their use was written, and that it was used to provide after-the-fact legal support for harsh interrogation techniques. A Department of Justice 2009 report regarding prisoner abuses reportedly stated the memos were prepared one month after Zubaydah had already been subjected to the specific techniques authorized in an August 1, 2002, memo. John Kiriakou stated in July 2009 that Zubaydah was waterboarded in the early summer of 2002, months before the August 1, 2002, memo was written. The memo described ten techniques which the interrogators wanted to use: "(1) attention grasp, (2) walling, (3) facial hold, (4) facial slap (insult slap), (5) cramped confinement, (6) wall standing, (7) stress positions, (8) sleep deprivation, (9) insects placed in a confinement box, and (10) the waterboard." Many of the techniques were, until then, generally considered illegal. Many other techniques developed by the CIA were held to constitute inhumane and degrading treatment and torture under the United Nations Convention against Torture and Article 3 of the European Convention on Human Rights. As reported later, many of these interrogation techniques were previously considered illegal under U.S. and international law and treaties at the time of Zubaydah's capture. For instance, the United States had prosecuted Japanese military officials after World War II and American soldiers after the Vietnam War for waterboarding. Since 1930, the United States had defined sleep deprivation as an illegal form of torture. Many other techniques developed by the CIA constitute inhuman and degrading treatment and torture under the United Nations Convention against Torture, and Article 3 of the European Convention on Human Rights. Ensuing interrogation At a CIA black site in Thailand, Zubaydah was subjected to various forms of increasingly harsh interrogation techniques, including temperature extremes, music played at debilitating volumes, and sexual humiliation. Zubaydah was also subjected to beatings, isolation, waterboarding, long-time standing, continuous cramped confinement, and sleep deprivation. Former CIA analyst and case officer John Kiriakou asserted that while Zubaydah was in CIA custody, a box of cockroaches were poured on him inside of a coffin he was confined to for two weeks, because of an irrational fear Zubaydah has of cockroaches. During Zubaydah's interrogation, President Bush learned he was on painkillers for his wounds and was proving resistant. He said to the CIA director George Tenet, "Who authorized putting him on pain medication?" It was later reported that Zubaydah was denied painkillers during his interrogation. Waterboarding Zubaydah was one of three or more high-value detainees to be waterboarded. The Bush administration in 2007 said that Zubaydah had been waterboarded once. John Kiriakou, a CIA officer who had seen the cables regarding Zubaydah's interrogation, publicly said in 2009 that Zubaydah was waterboarded once for 35 seconds before he started talking. Intelligence sources claimed as early as 2008 that Zubaydah had been waterboarded no less than ten times in the span of one week. Zubaydah was waterboarded 83 times within the month of August 2002, the month the CIA was authorized to use this enhanced interrogation techniques for him. In January 2010, Kiriakou, in a memoir, said, "Now we know that Zubaydah was waterboarded eighty-three times in a single month, raising questions about how much useful information he actually supplied." 2003 transfer to Guantanamo In August 2010, the Associated Press reported that the CIA, having concluded its agents had gotten most of the information from Zubaydah, in September 2003 transferred him and three other high-value detainees to Guantanamo. They were held at what was informally known as "Strawberry Fields", a secret camp within the complex built especially for former CIA detainees. Concerned that a pending Supreme Court decision, Rasul v. Bush (2004), might go against the Bush administration and require providing the prisoners with counsel and having to reveal data about them, on March 27, 2004, the CIA took the four men back into custody and transported them out of Guantanamo to one of their secret sites. At the time, the moves were all kept secret. International Committee of the Red Cross report In February 2007, the International Committee of the Red Cross concluded a report on the treatment of "14 high-value detainees", who had been held by the CIA and, after September 2006, by the military at Guantanamo. The ICRC described the twelve enhanced interrogation techniques covered in the OLC memos to the CIA: suffocation by water (which is described as "torture" by numerous US officials), prolonged stress standing position, beatings by use of a collar, beating and kicking, confinement in a box, prolonged nudity, sleep deprivation, exposure to cold temperature, prolonged shackling, threats of ill-treatment, forced shaving, and deprivation/restricted provision of solid food. Zubaydah was the only detainee of the 14 interviewed who had been subjected to all 12 of these interrogation techniques. He was also the only one of the 14 detainees to be put into close confinement. May 30, 2005, memo The final memo mentioned Zubaydah several times. It claimed that due to the enhanced interrogation techniques, Zubaydah "provided significant information on two operatives, [including] José Padilla[,] who planned to build and detonate a 'dirty bomb' in the Washington DC area." This claim is strongly disputed by Ali Soufan, the FBI interrogator who first interrogated Zubaydah following his capture, by traditional means. He said the most valuable information was gained before torture was used. Other intelligence officers have also disputed that claim. Soufan, when asked in 2009 by Senator Sheldon Whitehouse during a Congressional hearing if the memo was incorrect, testified that it was. The memo noted that not all of the waterboarding sessions were necessary for Zubaydah, since the on-scene interrogation team determined he had stopped producing actionable intelligence. The memo reads: This is not to say that the interrogation program has worked perfectly. According to the IG Report, the CIA, at least initially, could not always distinguish detainees who had information but were successfully resisting interrogation from those who did not actually have the information. See IG Report at 83–85. On at least one occasion, this may have resulted in what might be deemed in retrospect to have been the unnecessary use of enhanced techniques. On that occasion, although the on-scene interrogation team judged Zubaydah to be compliant, elements within CIA Headquarters still believed he was withholding information. See id at 84. At the direction of CIA Headquarters, interrogators therefore used the waterboard one more time on Zubaydah. John McLaughlin, former acting CIA director, stated in 2006, "I totally disagree with the view that the capture of Zubaydah was unimportant. Zubaydah was woven through all of the intelligence prior to 9/11 that signaled a major attack was coming, and his capture yielded a great deal of important information." In his 2007 memoir, former CIA Director George Tenet writes: A published report in 2006 contended that Zubaydah was mentally unstable and that the administration had overstated his importance. Baloney. Zubaydah had been at the crossroads of many al-Qa'ida operations and was in position to – and did – share critical information with his interrogators. Apparently, the source of the rumor that Zubaydah was unbalanced was his personal diary, in which he adopted various personas. From that shaky perch, some junior Freudians leapt to the conclusion that Zubaydah had multiple personalities. In fact, Agency psychiatrists eventually determined that in his diary he was using a sophisticated literary device to express himself. Intelligence obtained from Zubaydah and its after effects Zubaydah's capture was touted as the biggest of the War on Terror until that of Khalid Sheikh Mohammed. The director of the FBI stated Zubaydah's capture would help deter future attacks. In a speech in 2006, President Bush claimed that Zubaydah revealed useful intelligence when enhanced interrogation was used, including identification of two important suspects and information that allegedly helped foil a terrorist attack on American soil. These claims directly conflict with the reports of the FBI agents who first interrogated Zubaydah. He gave them the names before torture was used, and the third piece of information came from other sources who had been receiving crucial pieces of information from him without the use of harsher techniques, as well as other government officials. Iraq War (2003) The Bush administration relied on some of Zubaydah's claims in justifying the invasion of Iraq. U.S. officials stated that the allegations that Iraq and al-Qaeda were linked in the training of people on chemical weapons came from Zubaydah. The officials noted there was no independent verification of his claims. The U.S. government included statements made by Zubaydah in regards to al Qaeda's ability to obtain a dirty bomb to show a link between Iraq and al Qaeda. According to a Senate Intelligence Committee report of 2004, Zubaydah said that "he had heard that an important al Qaeda associate, Abu Musab al Zarqawi, and others had good relationships with Iraqi intelligence." However, the year before, in June 2003, Zubaydah and Khalid Sheikh Mohammed were reported as saying there was no link between Saddam Hussein and al Qaeda. In the Senate Armed Services Committee 2008 report on the abuses of detainees, the Bush administration was described as having applied pressure to interrogators to find a link between Iraq and al Qaeda prior to the Iraq War. Major Paul Burney, a psychiatrist with the United States Army, said to the committee, "while we were [at Guantanamo] a large part of the time we were focused on trying to establish a link between al Qaeda and Iraq and we were not being successful." He said that higher-ups were "frustrated" and applied "more and more pressure to resort to measures that might produce more immediate results." Colonel Lawrence B. Wilkerson, the former chief of staff for former Secretary of State Colin Powell said: Likewise, what I have learned is that as the administration authorized harsh interrogation in April and May 2002—well before the Justice Department had rendered any legal opinion—its principal priority for intelligence was not aimed at pre-empting another terrorist attack on the U.S. but discovering a smoking gun linking Iraq and al-Qa'ida. So furious was this effort that on one particular detainee, even when the interrogation team had reported to Cheney's office that their detainee "was compliant" (meaning the team recommended no more torture), the VP's office ordered them to continue the enhanced methods. The detainee had not revealed any al-Qa'ida-Baghdad contacts yet. This ceased only after Ibn al-Shaykh al-Libi, under waterboarding in Egypt, "revealed" such contacts. Of course, later we learned that al-Libi revealed these contacts only to get the torture to stop. Concerns In 2004, media coverage of Abu Zubaydah began listing him as a "disappeared" prisoner, stating he had no access to the International Red Cross. In February 2005, the CIA was reported as uncomfortable keeping Zubaydah in indefinite custody. Less than 18 months later, Zubaydah and the thirteen other high-value detainees who had been in secret CIA custody were transferred to the Guantanamo Bay detention camp. After his transfer, the CIA denied access to Zubaydah. In 2008, the Office of the Inspector General, Department of Justice, complained that it had been prevented from seeing him, although it was conducting a study of the US treatment of its detainees. Zubaydah's mental health Some people are concerned about Zubaydah's mental stability and how that has affected information he has given to interrogators. Ron Suskind noted in his book, The One Percent Doctrine: Deep Inside America's Pursuit of Its Enemies Since 9/11 (2006), that Zubaydah was mentally ill or disabled due to a severe head injury. He described Zubaydah as keeping a diary "in the voice of three people: Hani 1, Hani 2, and Hani 3"—a boy, a young man and a middle-aged alter ego. Zubaydah's diaries spanned ten years and recorded in numbing detail "what he ate, or wore, or trifling things [people] said". Dan Coleman, then the FBI's top al-Qaeda analyst, told a senior bureau official, "This guy is insane, certifiable, split personality." According to Suskind, this judgment was "echoed at the top of CIA and was briefed to the President and Vice President." Coleman stated Zubaydah was a "safehouse keeper" with mental problems, who "claimed to know more about al-Qaeda and its inner workings than he really did." Joseph Margulies, Zubaydah's co-counsel, wrote in an op-ed in the Los Angeles Times in 2009: Partly as a result of injuries he suffered while he was fighting the communists in Afghanistan, partly as a result of how those injuries were exacerbated by the CIA and partly as a result of his extended isolation, Zubaydah's mental grasp is slipping away. Today, he suffers blinding headaches and has permanent brain damage. He has an excruciating sensitivity to sounds, hearing what others do not. The slightest noise drives him nearly insane. In the last two years alone, he has experienced about 200 seizures. Already, he cannot picture his mother's face or recall his father's name. Gradually, his past, like his future, eludes him. Legal status President Bush referred to Zubaydah in a speech to Congress September 2006 requesting a bill to authorize military commissions, following the U.S. Supreme Court ruling in Hamdan v. Rumsfeld (2006) that held the tribunals as formulated by the executive branch were unconstitutional. Congress rapidly passed legislation that was signed by the president. Less than one month after Zubaydah's capture, Justice Department officials said Zubaydah was "a near-ideal candidate for a tribunal trial". Several months later in 2002, US officials said there was "no rush" to try Zubaydah via military commission. At his Combatant Status Review Tribunal in 2007, Zubaydah said he was told that the CIA realized he was not significant. "They told me, 'Sorry, we discover that you are not Number 3, not a partner, not even a fighter, said Zubaydah, speaking in broken English, according to the new transcript of a Combatant Status Review Tribunal held at the U.S. military prison in Guantanamo Bay, Cuba. Abu Zubaydah's lawyers, including Joseph Margulies and George Brent Mickum IV, filed a lawsuit in July 2008 challenging his detention at Guantanamo Bay detention camps after the Boumediene v. Bush ruling. The judge overseeing the case, Richard W. Roberts, failed to rule on any motions related to the case, even the preliminary ones. This led Zubaydah's lawyers to file a motion asking Judge Roberts to recuse himself for nonfeasance in January 2015. On March 16, 2016, Roberts retired early from the federal bench, citing unspecified health issues. The U.S. government has not officially charged Zubaydah with any crimes. The Senate Intelligence Committee report on CIA torture reported that Zubaydah's CIA interrogators wanted him to "remain in isolation and incommunicado for the remainder of his life." Joint Review Task Force When he assumed office in January 2009, President Barack Obama made a number of promises about the future of Guantanamo. He promised the use of torture would cease at the camp. He promised to institute a new review system. That new review system was composed of officials from six departments, where the OARDEC reviews were conducted entirely by the Department of Defense. When it reported back, a year later, the Joint Review Task Force classified some individuals as too dangerous to be transferred from Guantanamo, even though there was no evidence to justify laying charges against them. On April 9, 2013, that document was made public after a Freedom of Information Act request. Zayn al-lbidin Muhammed Husayn was one of the 71 individuals deemed too innocent to charge but too dangerous to release. Although Obama promised that those deemed too innocent to charge but too dangerous to release would start to receive reviews from a Periodic Review Board, less than a quarter of men have received a review. European Court of Human Rights decision On 24 July 2014, the European Court of Human Rights (ECHR) ruled that Poland had violated the European Convention on Human Rights when it cooperated with US allowing the CIA to hold and torture Zubaydah and Abd al-Rahim al-Nashiri on its territory in 2002–2003. The court ordered the Polish government to pay each of the men €100,000 in damages. It also awarded Zubaydah €30,000 to cover his costs. On 31 May 2018, the ECHR ruled that Romania and Lithuania also violated the rights of Abu Zubaydah and Abd al-Rahim al-Nashiri in 2003–2005 and in 2005–2006 respectively, and Lithuania and Romania were ordered to pay 100,000 euros in damages each to Abu Zubaydah and Abd al-Nashiri.

Arithmetic

Arithmetic (from the Greek ἀριθμός arithmos, 'number' and τική [τέχνη], tiké [téchne], 'art' or 'craft') is a branch of mathematics that consists of the study of numbers, especially concerning the properties of the traditional operations on them—addition, subtraction, multiplication, division, exponentiation, and extraction of roots. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms arithmetic and higher arithmetic were used until the beginning of the 20th century as synonyms for number theory, and are sometimes still used to refer to a wider part of number theory. History The prehistory of arithmetic is limited to a small number of artifacts, which may indicate the conception of addition and subtraction, the best-known being the Ishango bone from central Africa, dating from somewhere between 20,000 and 18,000 BC, although its interpretation is disputed. The earliest written records indicate the Egyptians and Babylonians used all the elementary arithmetic operations, namely addition, subtraction, multiplication, and division, as early as 2000 BC. These artifacts do not always reveal the specific process used for solving problems, but the characteristics of the particular numeral system strongly influence the complexity of the methods. The hieroglyphic system for Egyptian numerals, like the later Roman numerals, descended from tally marks used for counting. In both cases, this origin resulted in values that used a decimal base, but did not include positional notation. Complex calculations with Roman numerals required the assistance of a counting board (or the Roman abacus) to obtain the results. Early number systems that included positional notation were not decimal, including the sexagesimal (base 60) system for Babylonian numerals, and the vigesimal (base 20) system that defined Maya numerals. Because of this place-value concept, the ability to reuse the same digits for different values contributed to simpler and more efficient methods of calculation. The continuous historical development of modern arithmetic starts with the Hellenistic civilization of ancient Greece, although it originated much later than the Babylonian and Egyptian examples. Prior to the works of Euclid around 300 BC, Greek studies in mathematics overlapped with philosophical and mystical beliefs. For example, Nicomachus summarized the viewpoint of the earlier Pythagorean approach to numbers, and their relationships to each other, in his Introduction to Arithmetic. Greek numerals were used by Archimedes, Diophantus and others in a positional notation not very different from the modern notation. The ancient Greeks lacked a symbol for zero until the Hellenistic period, and they used three separate sets of symbols as digits: one set for the units place, one for the tens place, and one for the hundreds. For the thousands place, they would reuse the symbols for the units place, and so on. Their addition algorithm was identical to the modern method, and their multiplication algorithm was only slightly different. Their long division algorithm was the same, and the digit-by-digit square root algorithm, popularly used as recently as the 20th century, was known to Archimedes (who may have invented it). He preferred it to Hero's method of successive approximation because, once computed, a digit does not change, and the square roots of perfect squares, such as 7485696, terminate immediately as 2736. For numbers with a fractional part, such as 546.934, they used negative powers of 60—instead of negative powers of 10 for the fractional part 0.934. The ancient Chinese had advanced arithmetic studies dating from the Shang Dynasty and continuing through the Tang Dynasty, from basic numbers to advanced algebra. The ancient Chinese used a positional notation similar to that of the Greeks. Since they also lacked a symbol for zero, they had one set of symbols for the units place, and a second set for the tens place. For the hundreds place, they then reused the symbols for the units place, and so on. Their symbols were based on the ancient counting rods. The exact time where the Chinese started calculating with positional representation is unknown, though it is known that the adoption started before 400 BC. The ancient Chinese were the first to meaningfully discover, understand, and apply negative numbers. This is explained in the Nine Chapters on the Mathematical Art (Jiuzhang Suanshu), which was written by Liu Hui dated back to 2nd century BC. The gradual development of the Hindu–Arabic numeral system independently devised the place-value concept and positional notation, which combined the simpler methods for computations with a decimal base, and the use of a digit representing 0. This allowed the system to consistently represent both large and small integers—an approach which eventually replaced all other systems. In the early the Indian mathematician Aryabhata incorporated an existing version of this system in his work, and experimented with different notations. In the 7th century, Brahmagupta established the use of 0 as a separate number, and determined the results for multiplication, division, addition and subtraction of zero and all other numbers—except for the result of division by zero. His contemporary, the Syriac bishop Severus Sebokht (650 AD) said, "Indians possess a method of calculation that no word can praise enough. Their rational system of mathematics, or of their method of calculation. I mean the system using nine symbols." The Arabs also learned this new method and called it hesab. Although the Codex Vigilanus described an early form of Arabic numerals (omitting 0) by 976 AD, Leonardo of Pisa (Fibonacci) was primarily responsible for spreading their use throughout Europe after the publication of his book Liber Abaci in 1202. He wrote, "The method of the Indians (Latin Modus Indorum) surpasses any known method to compute. It's a marvelous method. They do their computations using nine figures and symbol zero". In the Middle Ages, arithmetic was one of the seven liberal arts taught in universities. The flourishing of algebra in the medieval Islamic world, and also in Renaissance Europe, was an outgrowth of the enormous simplification of computation through decimal notation. Various types of tools have been invented and widely used to assist in numeric calculations. Before Renaissance, they were various types of abaci. More recent examples include slide rules, nomograms and mechanical calculators, such as Pascal's calculator. At present, they have been supplanted by electronic calculators and computers. Arithmetic operations The basic arithmetic operations are addition, subtraction, multiplication and division, although arithmetic also includes more advanced operations, such as manipulations of percentages, square roots, exponentiation, logarithmic functions, and even trigonometric functions, in the same vein as logarithms (prosthaphaeresis). Arithmetic expressions must be evaluated according to the intended sequence of operations. There are several methods to specify this, either—most common, together with infix notation—explicitly using parentheses and relying on precedence rules, or using a prefix or postfix notation, which uniquely fix the order of execution by themselves. Any set of objects upon which all four arithmetic operations (except division by zero) can be performed, and where these four operations obey the usual laws (including distributivity), is called a field. Addition Addition, denoted by the symbol , is the most basic operation of arithmetic. In its simple form, addition combines two numbers, the addends or terms, into a single number, the sum of the numbers (such as or ). Adding finitely many numbers can be viewed as repeated simple addition; this procedure is known as summation, a term also used to denote the definition for "adding infinitely many numbers" in an infinite series. Repeated addition of the number 1 is the most basic form of counting; the result of adding is usually called the successor of the original number. Addition is commutative and associative, so the order in which finitely many terms are added does not matter. The number has the property that, when added to any number, it yields that same number; so, it is the identity element of addition, or the additive identity. For every number , there is a number denoted , called the opposite of , such that and . So, the opposite of is the inverse of with respect to addition, or the additive inverse of . For example, the opposite of is , since . Addition can also be interpreted geometrically, as in the following example. If we have two sticks of lengths 2 and 5, then, if the sticks are aligned one after the other, the length of the combined stick becomes 7, since . Subtraction Subtraction, denoted by the symbol , is the inverse operation to addition. Subtraction finds the difference between two numbers, the minuend minus the subtrahend: Resorting to the previously established addition, this is to say that the difference is the number that, when added to the subtrahend, results in the minuend: For positive arguments and holds: If the minuend is larger than the subtrahend, the difference is positive. If the minuend is smaller than the subtrahend, the difference is negative. In any case, if minuend and subtrahend are equal, the difference Subtraction is neither commutative nor associative. For that reason, the construction of this inverse operation in modern algebra is often discarded in favor of introducing the concept of inverse elements (as sketched under ), where subtraction is regarded as adding the additive inverse of the subtrahend to the minuend, that is, . The immediate price of discarding the binary operation of subtraction is the introduction of the (trivial) unary operation, delivering the additive inverse for any given number, and losing the immediate access to the notion of difference, which is potentially misleading when negative arguments are involved. For any representation of numbers, there are methods for calculating results, some of which are particularly advantageous in exploiting procedures, existing for one operation, by small alterations also for others. For example, digital computers can reuse existing adding-circuitry and save additional circuits for implementing a subtraction, by employing the method of two's complement for representing the additive inverses, which is extremely easy to implement in hardware (negation). The trade-off is the halving of the number range for a fixed word length. A formerly wide spread method to achieve a correct change amount, knowing the due and given amounts, is the counting up method, which does not explicitly generate the value of the difference. Suppose an amount P is given in order to pay the required amount Q, with P greater than Q. Rather than explicitly performing the subtraction P − Q = C and counting out that amount C in change, money is counted out starting with the successor of Q, and continuing in the steps of the currency, until P is reached. Although the amount counted out must equal the result of the subtraction P − Q, the subtraction was never really done and the value of P − Q is not supplied by this method. Multiplication Multiplication, denoted by the symbols or , is the second basic operation of arithmetic. Multiplication also combines two numbers into a single number, the product. The two original numbers are called the multiplier and the multiplicand, mostly both are simply called factors. Multiplication may be viewed as a scaling operation. If the numbers are imagined as lying in a line, multiplication by a number greater than 1, say x, is the same as stretching everything away from 0 uniformly, in such a way that the number 1 itself is stretched to where x was. Similarly, multiplying by a number less than 1 can be imagined as squeezing towards 0, in such a way that 1 goes to the multiplicand. Another view on multiplication of integer numbers (extendable to rationals but not very accessible for real numbers) is by considering it as repeated addition. For example. corresponds to either adding times a , or times a , giving the same result. There are different opinions on the advantageousness of these paradigmata in math education. Multiplication is commutative and associative; further, it is distributive over addition and subtraction. The multiplicative identity is 1, since multiplying any number by 1 yields that same number. The multiplicative inverse for any number except  is the reciprocal of this number, because multiplying the reciprocal of any number by the number itself yields the multiplicative identity .  is the only number without a multiplicative inverse, and the result of multiplying any number and is again One says that is not contained in the multiplicative group of the numbers. The product of a and b is written as or . When a or b are expressions not written simply with digits, it is also written by simple juxtaposition: ab. In computer programming languages and software packages (in which one can only use characters normally found on a keyboard), it is often written with an asterisk: a * b. Algorithms implementing the operation of multiplication for various representations of numbers are by far more costly and laborious than those for addition. Those accessible for manual computation either rely on breaking down the factors to single place values and applying repeated addition, or on employing tables or slide rules, thereby mapping multiplication to addition and vice versa. These methods are outdated and are gradually replaced by mobile devices. Computers utilize diverse sophisticated and highly optimized algorithms, to implement multiplication and division for the various number formats supported in their system. Division Division, denoted by the symbols or , is essentially the inverse operation to multiplication. Division finds the quotient of two numbers, the dividend divided by the divisor. Under common rules, dividend divided by zero is undefined. For distinct positive numbers, if the dividend is larger than the divisor, the quotient is greater than 1, otherwise it is less than or equal to 1 (a similar rule applies for negative numbers). The quotient multiplied by the divisor always yields the dividend. Division is neither commutative nor associative. So as explained in , the construction of the division in modern algebra is discarded in favor of constructing the inverse elements with respect to multiplication, as introduced in . Hence division is the multiplication of the dividend with the reciprocal of the divisor as factors, that is, Within the natural numbers, there is also a different but related notion called Euclidean division, which outputs two numbers after "dividing" a natural (numerator) by a natural (denominator): first a natural (quotient), and second a natural (remainder) such that and In some contexts, including computer programming and advanced arithmetic, division is extended with another output for the remainder. This is often treated as a separate operation, the Modulo operation, denoted by the symbol or the word , though sometimes a second output for one "divmod" operation. In either case, Modular arithmetic has a variety of use cases. Different implementations of division (floored, truncated, Euclidean, etc.) correspond with different implementations of modulus. Fundamental theorem of arithmetic The fundamental theorem of arithmetic states that any integer greater than 1 has a unique prime factorization (a representation of a number as the product of prime factors), excluding the order of the factors. For example, 252 only has one prime factorization: 252 = 2 × 3 × 7 Euclid's Elements first introduced this theorem, and gave a partial proof (which is called Euclid's lemma). The fundamental theorem of arithmetic was first proven by Carl Friedrich Gauss. The fundamental theorem of arithmetic is one of the reasons why 1 is not considered a prime number. Other reasons include the sieve of Eratosthenes, and the definition of a prime number itself (a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.). Decimal arithmetic refers exclusively, in common use, to the written numeral system employing arabic numerals as the digits for a radix 10 ("decimal") positional notation; however, any numeral system based on powers of 10, e.g., Greek, Cyrillic, Roman, or Chinese numerals may conceptually be described as "decimal notation" or "decimal representation". Modern methods for four fundamental operations (addition, subtraction, multiplication and division) were first devised by Brahmagupta of India. This was known during medieval Europe as "Modus Indorum" or Method of the Indians. Positional notation (also known as "place-value notation") refers to the representation or encoding of numbers using the same symbol for the different orders of magnitude (e.g., the "ones place", "tens place", "hundreds place") and, with a radix point, using those same symbols to represent fractions (e.g., the "tenths place", "hundredths place"). For example, 507.36 denotes 5 hundreds (102), plus 0 tens (101), plus 7 units (100), plus 3 tenths (10−1) plus 6 hundredths (10−2). The concept of 0 as a number comparable to the other basic digits is essential to this notation, as is the concept of 0's use as a placeholder, and as is the definition of multiplication and addition with 0. The use of 0 as a placeholder and, therefore, the use of a positional notation is first attested to in the Jain text from India entitled the Lokavibhâga, dated 458 AD and it was only in the early 13th century that these concepts, transmitted via the scholarship of the Arabic world, were introduced into Europe by Fibonacci using the Hindu–Arabic numeral system. Algorism comprises all of the rules for performing arithmetic computations using this type of written numeral. For example, addition produces the sum of two arbitrary numbers. The result is calculated by the repeated addition of single digits from each number that occupies the same position, proceeding from right to left. An addition table with ten rows and ten columns displays all possible values for each sum. If an individual sum exceeds the value 9, the result is represented with two digits. The rightmost digit is the value for the current position, and the result for the subsequent addition of the digits to the left increases by the value of the second (leftmost) digit, which is always one (if not zero). This adjustment is termed a carry of the value 1. The process for multiplying two arbitrary numbers is similar to the process for addition. A multiplication table with ten rows and ten columns lists the results for each pair of digits. If an individual product of a pair of digits exceeds 9, the carry adjustment increases the result of any subsequent multiplication from digits to the left by a value equal to the second (leftmost) digit, which is any value from (). Additional steps define the final result. Similar techniques exist for subtraction and division. The creation of a correct process for multiplication relies on the relationship between values of adjacent digits. The value for any single digit in a numeral depends on its position. Also, each position to the left represents a value ten times larger than the position to the right. In mathematical terms, the exponent for the radix (base) of 10 increases by 1 (to the left) or decreases by 1 (to the right). Therefore, the value for any arbitrary digit is multiplied by a value of the form 10n with integer n. The list of values corresponding to all possible positions for a single digit is written Repeated multiplication of any value in this list by 10 produces another value in the list. In mathematical terminology, this characteristic is defined as closure, and the previous list is described as . It is the basis for correctly finding the results of multiplication using the previous technique. This outcome is one example of the uses of number theory. Compound unit arithmetic Compound unit arithmetic is the application of arithmetic operations to mixed radix quantities such as feet and inches; gallons and pints; pounds, shillings and pence; and so on. Before decimal-based systems of money and units of measure, compound unit arithmetic was widely used in commerce and industry. Basic arithmetic operations The techniques used in compound unit arithmetic were developed over many centuries and are well documented in many textbooks in many different languages. In addition to the basic arithmetic functions encountered in decimal arithmetic, compound unit arithmetic employs three more functions: , in which a compound quantity is reduced to a single quantity—for example, conversion of a distance expressed in yards, feet and inches to one expressed in inches. , the inverse function to reduction, is the conversion of a quantity that is expressed as a single unit of measure to a compound unit, such as expanding 24 oz to . is the conversion of a set of compound units to a standard form—for example, rewriting "" as "". Knowledge of the relationship between the various units of measure, their multiples and their submultiples forms an essential part of compound unit arithmetic. Principles of compound unit arithmetic There are two basic approaches to compound unit arithmetic: where all the compound unit variables are reduced to single unit variables, the calculation performed and the result expanded back to compound units. This approach is suited for automated calculations. A typical example is the handling of time by Microsoft Excel where all time intervals are processed internally as days and decimal fractions of a day. in which each unit is treated separately and the problem is continuously normalized as the solution develops. This approach, which is widely described in classical texts, is best suited for manual calculations. An example of the ongoing normalization method as applied to addition is shown below. The addition operation is carried out from right to left; in this case, pence are processed first, then shillings followed by pounds. The numbers below the "answer line" are intermediate results. The total in the pence column is 25. Since there are 12 pennies in a shilling, 25 is divided by 12 to give 2 with a remainder of 1. The value "1" is then written to the answer row and the value "2" carried forward to the shillings column. This operation is repeated using the values in the shillings column, with the additional step of adding the value that was carried forward from the pennies column. The intermediate total is divided by 20 as there are 20 shillings in a pound. The pound column is then processed, but as pounds are the largest unit that is being considered, no values are carried forward from the pounds column. For the sake of simplicity, the example chosen did not have farthings. Operations in practice During the 19th and 20th centuries various aids were developed to aid the manipulation of compound units, particularly in commercial applications. The most common aids were mechanical tills which were adapted in countries such as the United Kingdom to accommodate pounds, shillings, pennies and farthings, and ready reckoners, which are books aimed at traders that catalogued the results of various routine calculations such as the percentages or multiples of various sums of money. One typical booklet that ran to 150 pages tabulated multiples "from one to ten thousand at the various prices from one farthing to one pound". The cumbersome nature of compound unit arithmetic has been recognized for many years—in 1586, the Flemish mathematician Simon Stevin published a small pamphlet called De Thiende ("the tenth") in which he declared the universal introduction of decimal coinage, measures, and weights to be merely a question of time. In the modern era, many conversion programs, such as that included in the Microsoft Windows 7 operating system calculator, display compound units in a reduced decimal format rather than using an expanded format (e.g. "2.5 ft" is displayed rather than ). Number theory Until the 19th century, number theory was a synonym of "arithmetic". The addressed problems were directly related to the basic operations and concerned primality, divisibility, and the solution of equations in integers, such as Fermat's Last Theorem. It appeared that most of these problems, although very elementary to state, are very difficult and may not be solved without very deep mathematics involving concepts and methods from many other branches of mathematics. This led to new branches of number theory such as analytic number theory, algebraic number theory, Diophantine geometry and arithmetic algebraic geometry. Wiles' proof of Fermat's Last Theorem is a typical example of the necessity of sophisticated methods, which go far beyond the classical methods of arithmetic, for solving problems that can be stated in elementary arithmetic. Arithmetic in education Primary education in mathematics often places a strong focus on algorithms for the arithmetic of natural numbers, integers, fractions, and decimals (using the decimal place-value system). This study is sometimes known as algorism. The difficulty and unmotivated appearance of these algorithms has long led educators to question this curriculum, advocating the early teaching of more central and intuitive mathematical ideas. One notable movement in this direction was the New Math of the 1960s and 1970s, which attempted to teach arithmetic in the spirit of axiomatic development from set theory, an echo of the prevailing trend in higher mathematics. Also, arithmetic was used by Islamic Scholars in order to teach application of the rulings related to Zakat and Irth. This was done in a book entitled The Best of Arithmetic by Abd-al-Fattah-al-Dumyati. The book begins with the foundations of mathematics and proceeds to its application in the later chapters.

Andersonville, Georgia

Andersonville is a city in Sumter County, Georgia, United States. As of the 2020 census, the city had a population of 237. It is located in the southwest part of the state, approximately southwest of Macon on the Central of Georgia railroad. During the American Civil War, it was the site of a prisoner-of-war camp, which is now Andersonville National Historic Site. Andersonville is part of the Americus Micropolitan Statistical Area. History The hamlet of Anderson was named for John Anderson, a director of the South Western Railroad in 1853 when it was extended from Oglethorpe to Americus. It was known as Anderson Station until the US post office was established in November 1855. The government changed the name of the station from “Anderson” to “Andersonville” in order to avoid confusion with the post office in Anderson, South Carolina. During the Civil War, the Confederate army established Camp Sumter at Andersonville to house incoming Union prisoners of war. The overcrowded Andersonville Prison was notorious for its bad conditions, and nearly 13,000 prisoners died there. After the war, Henry Wirz was convicted for war crimes related to the command of the camp. His trial was later regarded as unfair by several groups, and a monument in his honor has been erected in Andersonville by the United Daughters of the Confederacy. The town also served as a supply depot during the war period. It included a post office, a depot, a blacksmith shop and stable, a couple of general stores, two saloons, a school, a Methodist church, and about a dozen houses. (Ben Dykes, who owned the land on which the prison was built, was both depot agent and postmaster.) Until the establishment of the prison, the area was entirely dependent on agriculture, supported by dark reddish brown sandy loams later mapped as Greenville and Red Bay soil series. After the close of the prison and end of the war, the town continued economically dependent on agriculture, primarily the cultivation of cotton as a commodity crop. It was not until 1968, when the large-scale mining of kaolin, bauxitic kaolin, and bauxite was begun by Mulcoa, Mullite Company of America, that the town was dramatically altered. This operation exploited of scrub oak wilderness into a massive mining and refining operation. The company now ships more than 2000 tons of refined ore from Andersonville each week. In 1974, long-time mayor Lewis Easterlin and a group of concerned citizens decided to promote tourism in the town, redeveloping Main Street to look much as it did during the American Civil War. The city of Andersonville and the Andersonville National Historic Site, location of the prison camp, are now tourist attractions. Geography Climate Demographics As of the census of 2000, there were 331 people, 124 households, and 86 families residing in the city. The population density was 254.1 people per square mile (98.3/km2). There were 142 housing units at an average density of 109.0 per square mile (42.2/km2). The racial makeup of the city was 65.26% White and 34.74% African American. Hispanic or Latino of any race were 1.21% of the population. There were 124 households, out of which 34.7% had children under the age of 18 living with them, 46.0% were married couples living together, 17.7% had a female householder with no husband present, and 30.6% were non-families. 26.6% of all households were made up of individuals, and 10.5% had someone living alone who was 65 years of age or older. The average household size was 2.67 and the average family size was 3.21. In the city, the population was spread out, with 27.8% under the age of 18, 9.4% from 18 to 24, 31.4% from 25 to 44, 19.3% from 45 to 64, and 12.1% who were 65 years of age or older. The median age was 36 years. For every 100 females, there were 105.6 males. For every 100 females age 18 and over, there were 97.5 males. The median income for a household in the city was $29,107, and the median income for a family was $30,972. Males had a median income of $26,591 versus $20,000 for females. The per capita income for the city was $15,168. About 19.8% of families and 23.0% of the population were below the poverty line, including 29.3% of those under age 18 and 13.5% of those age 65 or over.

https://en.wikipedia.org/wiki/Agra%20Canal

Agra Canal

The Agra Canal is an important Indian irrigation work which starts from Okhla in Delhi. The Agra canal originates from Okhla barrage, downstream of Nizamuddin bridge. The Canal receives its water from the Yamuna River at Okhla, about 10 km to the south of New Delhi. The weir across the Yamuna was constructed of locally quarried stone. It was about 800-yards long, and rises seven-feet above the summer level of the river. From Okhla the canal follows a route south then southeast for in the high land between the Khari-Nadi and the Yamuna and finally joins the Utanga River about below Agra. Navigable branches connect the canal with Mathura and Agra. The canal irrigates about 1.5 lakh MOS:DIGITS hectares in Agra, and Mathura in Uttar Pradesh, Faridabad in Haryana, Bharatpur in Rajasthan and also some parts of Delhi. History The canal opened in the year 1874. In the beginning, it was available for navigation, in Delhi, erstwhile Gurgaon, Mathura and Agra Districts, and Bharatpur State. Later, navigation was stopped in 1904 and the canal has, since then, been exclusively used for irrigation purposes only. At present, the canal does not flow in Gurgaon district, but only in Faridabad, which was earlier a part of Gurgaon. In recent times, Agra canal is an important landmark which separates Greater Faridabad from Faridabad. References The Agra Canal also has many places to visit along its coast.

https://en.wikipedia.org/wiki/Amakusa

Amakusa

, which means "Heaven's Grass," is a series of islands off the west coast of Kyushu, the southernmost of the four main islands of Japan. Geography The largest island of the Amakusa group is Shimoshima, which is 26.5 miles long and 13.5 miles at its widest (). It is situated at 32°20'N, 130°E, separated from the rest of Kumamoto Prefecture by the Yatsushiro Sea. While lacking high mountains with only four peaks surpassing , the island terrain is ruggedly hilly. To cope with the lack of flat arable land, farming is carried out on a terrace system of cultivation. History Amakusa, along with the neighboring Shimabara Peninsula, became the site of the Shimabara rebellion in the 17th century, led by Christians. Following the rebellion, Kakure Kirishitan, the Christians who had survived, continued to practice their faith in secret, despite severe persecution. Economy Amakusa produces a little coal and pottery stone, both being used by the potters of Hirado ware and Satsuma ware. Many kilns remain on the islands today, and pottery and pottery stone are still exported. Amakusa pottery has been recognised by the government. The retail company Muji brought out its own line of Hakuji home ware, which is produced out of ground translucent Amakusa stones kneaded into clay, using traditional techniques. People Hidenoshin Koyama, who built Thomas Blake Glover's House in Glover Garden, came from this island. Kenta and Ko-shin, two of the three members of Wanima come from the island of Amakusa. Government At present, the islands are organized as Amakusa District, Amakusa City, and Kami-amakusa City, all of which are under the administration of Kumamoto Prefecture. Transport The islands are served by Amakusa Airfield, located on the north end of Shimoshima. The islands are connected to the mainland by the Five Bridges of Amakusa and by ferry from Hondo and Matsushima. There are also ferries between the islands and the neighboring prefectures of Kagoshima Prefecture and Nagasaki Prefecture. The ferry from Oniike on the north Shimoshima to Kuchinotsu, at the southern tip of the Shimabara Peninsula, is run by the Shimabara Railway and operates hourly each day. The ferry boat from Tomioka Port in Reihoku, sailing north to Mogi in Nagasaki Prefecture, is operated by Yasuda Sangyo Kisen Co. Ltd. Two ferries from Shinwa and Ushibuka, in the south of Shimoshima, connect Amakusa to Nagashima in Kagoshima Prefecture.

https://en.wikipedia.org/wiki/Afterglow

Afterglow

An afterglow is a broad arch of whitish or pinkish sunlight in the sky that is scattered by fine particulates, like dust, suspended in the atmosphere. An afterglow may appear above the highest clouds in the hour of fading twilight or be reflected off high snowfields in mountain regions long after sunset. The particles produce a scattering effect upon the component parts of white light. The opposite of an afterglow is a foreglow, which occurs before sunrise. True alpenglow, which occurs long after sunset or long before sunrise, is caused by the backscattering of red sunlight by aerosols and fine dust particles low in the atmosphere. After sunset, alpenglow is an afterglow caused by the illumination of atmospheric particles by sunlight as it gets refracted and scattered through the Earth's atmosphere. The high-energy and high-frequency light is scattered out the most, while the remaining low-energy and -frequency light reaches the observer on the horizon at twilight. The backscattering of this light further turns it pinkish to reddish. This period of time is referred to as the blue hour and is widely treasured by photographers and painters. The afterglow persists until the Earth's shadow (terminator line) overtakes the sky above the observer as night falls and the stars appear. After the 1883 eruption of the volcano Krakatoa, a remarkable series of red sunsets appeared worldwide. An enormous amount of exceedingly fine dust were blown to a great height by the volcano's explosion, and then globally diffused by the high atmospheric winds. Edvard Munch's painting The Scream possibly depicts an afterglow during this period.

Ammonius Grammaticus

Ammonius Grammaticus (; ) was a 4th-century Egyptian priest who, after the destruction of the pagan temple at Alexandria (389), fled to Constantinople, where he became the tutor of the ecclesiastical historian Socrates. Life Ammonius was formerly identified as the author of a treatise titled Peri homoíōn kai diaphórōn léxeōn (περὶ ὁμοίων καὶ διαφόρων λέξεων, On the Differences of Synonymous Expressions). But it seems more probable that the real author was Herennius Philo of Byblus, who was born during the reign of Nero and lived till the reign of Hadrian, and that the treatise in its present form is a revision prepared by a later Byzantine editor, whose name may have been Ammonius.

https://en.wikipedia.org/wiki/Algebraic%20closure

Algebraic closure

In mathematics, particularly abstract algebra, an algebraic closure of a field K is an algebraic extension of K that is algebraically closed. It is one of many closures in mathematics. Using Zorn's lemma or the weaker ultrafilter lemma, it can be shown that every field has an algebraic closure, and that the algebraic closure of a field K is unique up to an isomorphism that fixes every member of K. Because of this essential uniqueness, we often speak of the algebraic closure of K, rather than an algebraic closure of K. The algebraic closure of a field K can be thought of as the largest algebraic extension of K. To see this, note that if L is any algebraic extension of K, then the algebraic closure of L is also an algebraic closure of K, and so L is contained within the algebraic closure of K. The algebraic closure of K is also the smallest algebraically closed field containing K, because if M is any algebraically closed field containing K, then the elements of M that are algebraic over K form an algebraic closure of K. The algebraic closure of a field K has the same cardinality as K if K is infinite, and is countably infinite if K is finite. Examples The fundamental theorem of algebra states that the algebraic closure of the field of real numbers is the field of complex numbers. The algebraic closure of the field of rational numbers is the field of algebraic numbers. There are many countable algebraically closed fields within the complex numbers, and strictly containing the field of algebraic numbers; these are the algebraic closures of transcendental extensions of the rational numbers, e.g. the algebraic closure of Q(π). For a finite field of prime power order q, the algebraic closure is a countably infinite field that contains a copy of the field of order qn for each positive integer n (and is in fact the union of these copies). Existence of an algebraic closure and splitting fields Let be the set of all monic irreducible polynomials in K[x]. For each , introduce new variables where . Let R be the polynomial ring over K generated by for all and all . Write with . Let I be the ideal in R generated by the . Since I is strictly smaller than R, Zorn's lemma implies that there exists a maximal ideal M in R that contains I. The field K1=R/M has the property that every polynomial with coefficients in K splits as the product of and hence has all roots in K1. In the same way, an extension K2 of K1 can be constructed, etc. The union of all these extensions is the algebraic closure of K, because any polynomial with coefficients in this new field has its coefficients in some Kn with sufficiently large n, and then its roots are in Kn+1, and hence in the union itself. It can be shown along the same lines that for any subset S of K[x], there exists a splitting field of S over K. Separable closure An algebraic closure Kalg of K contains a unique separable extension Ksep of K containing all (algebraic) separable extensions of K within Kalg. This subextension is called a separable closure of K. Since a separable extension of a separable extension is again separable, there are no finite separable extensions of Ksep, of degree > 1. Saying this another way, K is contained in a separably-closed algebraic extension field. It is unique (up to isomorphism). The separable closure is the full algebraic closure if and only if K is a perfect field. For example, if K is a field of characteristic p and if X is transcendental over K, is a non-separable algebraic field extension. In general, the absolute Galois group of K is the Galois group of Ksep over K. See also Algebraically closed field Algebraic extension Puiseux expansion Complete field References Field extensions

https://en.wikipedia.org/wiki/Advanced%20Power%20Management

Advanced Power Management

Advanced power management (APM) is an API developed by Intel and Microsoft and released in 1992 which enables an operating system running an IBM-compatible personal computer to work with the BIOS (part of the computer's firmware) to achieve power management. Revision 1.2 was the last version of the APM specification, released in 1996. ACPI is the successor to APM. Microsoft dropped support for APM in Windows Vista. The Linux kernel still mostly supports APM, though support for APM CPU idle was dropped in version 3.0. Overview APM uses a layered approach to manage devices. APM-aware applications (which include device drivers) talk to an OS-specific APM driver. This driver communicates to the APM-aware BIOS, which controls the hardware. There is the ability to opt out of APM control on a device-by-device basis, which can be used if a driver wants to communicate directly with a hardware device. Communication occurs both ways; power management events are sent from the BIOS to the APM driver, and the APM driver sends information and requests to the BIOS via function calls. In this way the APM driver is an intermediary between the BIOS and the operating system. Power management happens in two ways; through the above-mentioned function calls from the APM driver to the BIOS requesting power state changes, and automatically based on device activity. In APM 1.0 and APM 1.1, power management is almost fully controlled by the BIOS. In APM 1.2, the operating system can control PM time (e.g. suspend timeout). Power management events There are 12 power events (such as standby, suspend and resume requests, and low battery notifications), plus OEM-defined events, that can be sent from the APM BIOS to the operating system. The APM driver regularly polls for event change notifications. Power Management Events: APM functions There are 21 APM function calls defined that the APM driver can use to query power management statuses, or request power state transitions. Example function calls include letting the BIOS know about current CPU usage (the BIOS may respond to such a call by placing the CPU in a low-power state, or returning it to its full-power state), retrieving the current power state of a device, or requesting a power state change. Power states The APM specification defines system power states and device power states. System power states APM defines five power states for the computer system: Full On: The computer is powered on, and no devices are in a power saving mode. APM Enabled: The computer is powered on, and APM is controlling device power management as needed. APM Standby: Most devices are in their low-power state, the CPU is slowed or stopped, and the system state is saved. The computer can be returned to its former state quickly (in response to activity such as the user pressing a key on the keyboard). APM Suspend: Most devices are powered off, but the system state is saved. The computer can be returned to its former state, but takes a relatively long time. (Hibernation is a special form of the APM Suspend state). Off: The computer is turned off. Device power states APM also defines power states that APM-aware hardware can implement. There is no requirement that an APM-aware device implement all states. The four states are: Device On: The device is in full power mode. Device Power Managed: The device is still powered on, but some functions may not be available, or may have reduced performance. Device Low Power: The device is not working. Power is maintained so that the device may be 'woken up'. Device Off: The device is powered off. CPU The CPU core (defined in APM as the CPU clock, cache, system bus and system timers) is treated specially in APM, as it is the last device to be powered down, and the first device to be powered back up. The CPU core is always controlled through the APM BIOS (there is no option to control it through a driver). Drivers can use APM function calls to notify the BIOS about CPU usage, but it is up to the BIOS to act on this information; a driver cannot directly tell the CPU to go into a power saving state. In ATA drives The ATA specification defines APM provisions for hard drives via the subcommand , which specifies a trade-off between spin-down frequency and always-on performance. Unlike the BIOS-side APM, the ATA APM has never been deprecated. Aggressive spin-down frequencies may reduce drive lifespan by unnecessarily accumulating load cycles; most modern drives are specified to sustain 300,000 cycles and usually last at least 600,000. On the other hand, not spinning down the drive will cause extra power draw and heat generation; high temperatures also reduce the lifespan of hard drives.

https://en.wikipedia.org/wiki/Adolphe%20Sax

Adolphe Sax

Antoine-Joseph "Adolphe" Sax (; 6 November 1814 – 7 February 1894) was a Belgian inventor and musician who created the saxophone in the early 1840s, patenting it in 1846. He also invented the saxotromba, saxhorn and saxtuba. He played the flute and clarinet. Early life Antoine-Joseph Sax was born on 6 November 1814, in Dinant, in what is now Belgium, to Charles-Joseph Sax and his wife Marie-Joseph (Masson). While his given name was Antoine-Joseph, he was referred to as Adolphe from childhood. His father and mother were instrument designers themselves, who made several changes to the design of the French horn. Adolphe began to make his own instruments at an early age, entering two of his flutes and a clarinet into a competition at the age of 15. He subsequently studied performance on those two instruments as well as voice at the Royal Conservatory of Brussels. Sax faced many brushes with death. As a child he once fell from a height of three floors, hit his head on a stone and was believed dead. At the age of three, he drank a bowl full of acidic water mistaking it for milk, and later swallowed a pin. He received serious burns from a gunpowder explosion, and once fell onto a hot cast-iron frying pan, burning his side. Several times he avoided accidental poisoning and asphyxiation from sleeping in a room where varnished furniture was drying. Another time young Sax was struck on the head by a cobblestone and fell into a river, almost dying. His mother once said that "he's a child condemned to misfortune; he won't live." His neighbors called him "little Sax, the ghost". Career and later life After leaving the Royal Conservatory of Brussels, Sax began to experiment with new instrument designs, while his parents continued their business of making conventional instruments. Sax's first important invention was an improvement in bass clarinet design which he patented at the age of 24. He relocated permanently to Paris in 1842 and began working on a new set of valved bugles. While he did not invent this instrument, his examples were much more successful than those of his rivals and became known as saxhorns. Hector Berlioz was so enamoured of these that he arranged in February 1844 for one of his pieces to be played entirely on saxhorns. They were made in seven different sizes and paved the way for the creation of the flugelhorn. Today saxhorns are sometimes used in concert bands, marching bands, and orchestras. The saxhorn also laid the groundwork for the modern euphonium. Sax also developed the saxotromba family, valved brass instruments with narrower bore than the saxhorns, in 1845, though they survived only briefly. The use of saxhorns spread rapidly. The saxhorn valves were accepted as state-of-the-art in their time and remain largely unchanged today. The advances made by Adolphe Sax were soon followed by the British brass band movement which exclusively adopted the saxhorn family of instruments.<ref name=Herbert2000>T. Herbert, The British Brass Band: a Musical and Social History (Oxford: Oxford University Press, 2000), pp. 4–5.</ref> A decade after saxhorns became available, the Jedforest Instrumental Band (1854) and The Hawick Saxhorn Band (1855) were formed in the Scottish Borders. The period around 1840 saw Sax inventing the clarinette-bourdon, an early unsuccessful design of contrabass clarinet. On 28 June 1846 he patented the saxophone, intended for use in orchestras and military bands. By 1846 Sax had designed saxophones ranging from sopranino to subcontrabass although not all were built. Composer Hector Berlioz wrote approvingly of the new instrument in 1842 but despite his support saxophones did not become a standard part of the orchestra. Their ability to play technical passages easily like woodwinds yet project loudly like brass instruments led to their inclusion in military bands in France and elsewhere. Sax's reputation helped secure him a job teaching at the Paris Conservatory in 1857. He continued to make instruments later in life and presided over the new saxophone course at the Paris Conservatory. Legal troubles involving patents continued for over 20 years, with rival instrument makers attacking the legitimacy of his patents and Sax suing them for patent infringement. He was driven into bankruptcy three times: in 1852, 1873 and 1877. Sax suffered from lip cancer between 1853 and 1858 but made a full recovery. In 1894 he died in poverty in Paris and was interred in section 5 (Avenue de Montebello) at the Cimetière de Montmartre in Paris. Honors and awards In his birthplace Dinant in Belgium the Mr Sax's House is dedicated to his life and saxophones. 1849: Awarded the Chevalier rank of the Legion of Honour. 1867: 1e Grand Prix de la Facture Instrumentale'' at the 1867 Paris International Exposition 1995: In 1995, his likeness was featured on the front of Belgium's 200 Belgian Francs banknote. 2015: Google Doodle commemorated his 201st birthday.

https://en.wikipedia.org/wiki/Aspirated%20consonant

Aspirated consonant

In phonetics, aspiration is the strong burst of breath that accompanies either the release or, in the case of preaspiration, the closure of some obstruents. In English, aspirated consonants are allophones in complementary distribution with their unaspirated counterparts, but in some other languages, notably most South Asian languages (including Indian) and East Asian languages, the difference is contrastive. In dialects with aspiration, to feel or see the difference between aspirated and unaspirated sounds, one can put a hand or a lit candle in front of one's mouth, and say spin and then pin . One should either feel a puff of air or see a flicker of the candle flame with pin that one does not get with spin. Transcription In the International Phonetic Alphabet (IPA), aspirated consonants are written using the symbols for voiceless consonants followed by the aspiration modifier letter , a superscript form of the symbol for the voiceless glottal fricative . For instance, represents the voiceless bilabial stop, and represents the aspirated bilabial stop. Voiced consonants are seldom actually aspirated. Symbols for voiced consonants followed by , such as , typically represent consonants with murmured voiced release (see below). In the grammatical tradition of Sanskrit, aspirated consonants are called voiceless aspirated, and breathy-voiced consonants are called voiced aspirated. There are no dedicated IPA symbols for degrees of aspiration and typically only two degrees are marked: unaspirated and aspirated . An old symbol for light aspiration was , but this is now obsolete. The aspiration modifier letter may be doubled to indicate especially strong or long aspiration. Hence, the two degrees of aspiration in Korean stops are sometimes transcribed or and , but they are usually transcribed and , with the details of voice onset time given numerically. Preaspirated consonants are marked by placing the aspiration modifier letter before the consonant symbol: represents the preaspirated bilabial stop. Unaspirated or tenuis consonants are occasionally marked with the modifier letter for unaspiration , a superscript equals sign: . Usually, however, unaspirated consonants are left unmarked: . Phonetics Voiceless consonants are produced with the vocal folds open (spread) and not vibrating, and voiced consonants are produced when the vocal folds are fractionally closed and vibrating (modal voice). Voiceless aspiration occurs when the vocal folds remain open after a consonant is released. An easy way to measure this is by noting the consonant's voice onset time, as the voicing of a following vowel cannot begin until the vocal folds close. In some languages, such as Navajo, aspiration of stops tends to be phonetically realised as voiceless velar airflow; aspiration of affricates is realised as an extended length of the frication. Aspirated consonants are not always followed by vowels or other voiced sounds. For example, in Eastern Armenian, aspiration is contrastive even word-finally, and aspirated consonants occur in consonant clusters. In Wahgi, consonants are aspirated only when they are in final position. Degree The degree of aspiration varies: the voice onset time of aspirated stops is longer or shorter depending on the language or the place of articulation. Armenian and Cantonese have aspiration that lasts about as long as English aspirated stops, in addition to unaspirated stops. Korean has lightly-aspirated stops that fall between the Armenian and Cantonese unaspirated and aspirated stops as well as strongly-aspirated stops whose aspiration lasts longer than that of Armenian or Cantonese. (See voice onset time.) Aspiration varies with place of articulation. The Spanish voiceless stops have voice onset times (VOTs) of about 5, 10, and 30 milliseconds, and English aspirated have VOTs of about 60, 70, and 80 ms. Voice onset time in Korean has been measured at 20, 25, and 50 ms for and 90, 95, and 125 for . Doubling When aspirated consonants are doubled or geminated, the stop is held longer and then has an aspirated release. An aspirated affricate consists of a stop, fricative, and aspirated release. A doubled aspirated affricate has a longer hold in the stop portion and then has a release consisting of the fricative and aspiration. Preaspiration Icelandic and Faroese have consonants with preaspiration , and some scholars interpret them as consonant clusters as well. In Icelandic, preaspirated stops contrast with double stops and single stops: Preaspiration is also a feature of Scottish Gaelic: Preaspirated stops also occur in most Sami languages. For example, in Northern Sami, the unvoiced stop and affricate phonemes , , , , are pronounced preaspirated (, , , ) in medial or final position. Fricatives and sonorants Although most aspirated obstruents in the world's languages are stops and affricates, aspirated fricatives such as , or have been documented in Korean, though these are allophones of other phonemes. Similarly, aspirated fricatives and even aspirated nasals, approximants, and trills occur in a few Tibeto-Burman languages, in some Oto-Manguean languages, in the Hmongic language Hmu, and in the Siouan language Ofo. Some languages, such as Choni Tibetan, have as many as four contrastive aspirated fricatives , and . Voiced consonants with voiceless aspiration True aspirated voiced consonants, as opposed to murmured (breathy-voice) consonants such as the that are common among the languages of India, are extremely rare. They have been documented in Kelabit. Phonology Aspiration has varying significance in different languages. It is either allophonic or phonemic, and may be analyzed as an underlying consonant cluster. Allophonic In some languages, such as English, aspiration is allophonic. Stops are distinguished primarily by voicing, and voiceless stops are sometimes aspirated, while voiced stops are usually unaspirated. English voiceless stops are aspirated for most native speakers when they are word-initial or begin a stressed syllable. Pronouncing them as unaspirated in these positions, as is done by many Indian English speakers, may make them get confused with the corresponding voiced stop by other English-speakers. Conversely, this confusion does not happen with the native speakers of languages which have aspirated and unaspirated but not voiced stops, such as Mandarin Chinese. S+consonant clusters may vary between aspirated and nonaspirated depending upon if the cluster crosses a morpheme boundary or not. For instance, distend has unaspirated since it is not analyzed as two morphemes, but distaste has an aspirated middle because it is analyzed as dis- + taste and the word taste has an aspirated initial t. Word-final voiceless stops are sometimes aspirated. Voiceless stops in Pashto are slightly aspirated prevocalically in a stressed syllable. Phonemic In many languages, such as Armenian, Korean, Lakota, Thai, Indo-Aryan languages, Dravidian languages, Icelandic, Faroese, Ancient Greek, and the varieties of Chinese, tenuis and aspirated consonants are phonemic. Unaspirated consonants like and aspirated consonants like are separate phonemes, and words are distinguished by whether they have one or the other. Consonant cluster Alemannic German dialects have unaspirated as well as aspirated ; the latter series are usually viewed as consonant clusters. Tenseness In Danish and most southern varieties of German, the lenis consonants transcribed for historical reasons as are distinguished from their fortis counterparts , mainly in their lack of aspiration. Absence French, Standard Dutch, Afrikaans, Tamil, Finnish, Portuguese, Italian, Spanish, Russian, Polish, Latvian and Modern Greek are languages that do not have phonemic aspirated consonants. Examples Chinese Standard Chinese (Mandarin) has stops and affricates distinguished by aspiration: for instance, , . In pinyin, tenuis stops are written with letters that represent voiced consonants in English, and aspirated stops with letters that represent voiceless consonants. Thus d represents , and t represents . Wu Chinese and Southern Min has a three-way distinction in stops and affricates: . In addition to aspirated and unaspirated consonants, there is a series of muddy consonants, like . These are pronounced with slack or breathy voice: that is, they are weakly voiced. Muddy consonants as initial cause a syllable to be pronounced with low pitch or light (陽 yáng) tone. Indian languages Many Indo-Aryan languages have aspirated stops. Sanskrit, Hindustani, Bengali, Marathi, and Gujarati have a four-way distinction in stops: voiceless, aspirated, voiced, and breathy-voiced or voiced aspirated, such as . Punjabi has lost breathy-voiced consonants, which resulted in a tone system, and therefore has a distinction between voiceless, aspirated, and voiced: . Some of the Dravidian languages, such as Telugu, Malayalam, and Kannada, have a distinction between voiced and voiceless, aspirated and unaspirated only in loanwords from Indo-Aryan languages. In native Dravidian words, there is no distinction between these categories and stops are underspecified for voicing and aspiration. Armenian Most dialects of Armenian have aspirated stops, and some have breathy-voiced stops. Classical and Eastern Armenian have a three-way distinction between voiceless, aspirated, and voiced, such as . Western Armenian has a two-way distinction between aspirated and voiced: . Western Armenian aspirated corresponds to Eastern Armenian aspirated and voiced , and Western voiced corresponds to Eastern voiceless . Greek Some forms of Greek before the Koine Greek period are reconstructed as having aspirated stops. The Classical Attic dialect of Ancient Greek had a three-way distinction in stops like Eastern Armenian: . These series were called , , (psilá, daséa, mésa) "smooth, rough, intermediate", respectively, by Koine Greek grammarians. There were aspirated stops at three places of articulation: labial, coronal, and velar . Earlier Greek, represented by Mycenaean Greek, likely had a labialized velar aspirated stop , which later became labial, coronal, or velar depending on dialect and phonetic environment. The other Ancient Greek dialects, Ionic, Doric, Aeolic, and Arcadocypriot, likely had the same three-way distinction at one point, but Doric seems to have had a fricative in place of in the Classical period, and the Ionic and Aeolic dialects sometimes lost aspiration (psilosis). Later, during the Koine Greek period, the aspirated and voiced stops of Attic Greek lenited to voiceless and voiced fricatives, yielding in Medieval and Modern Greek. Cypriot Greek is notable for aspirating its inherited (and developed across word-boundaries) voiceless geminate stops, yielding the series /pʰː tʰː cʰː kʰː/. Other uses Debuccalization The term aspiration sometimes refers to the sound change of debuccalization, in which a consonant is lenited (weakened) to become a glottal stop or fricative . Breathy-voiced release So-called voiced aspirated consonants are nearly always pronounced instead with breathy voice, a type of phonation or vibration of the vocal folds. The modifier letter after a voiced consonant actually represents a breathy-voiced or murmured dental stop, as with the "voiced aspirated" bilabial stop in the Indo-Aryan languages. This consonant is therefore more accurately transcribed as , with the diacritic for breathy voice, or with the modifier letter , a superscript form of the symbol for the voiced glottal fricative . Some linguists restrict the double-dot subscript to murmured sonorants, such as vowels and nasals, which are murmured throughout their duration, and use the superscript hook-aitch for the breathy-voiced release of obstruents.

Arteriovenous malformation

Arteriovenous malformation is an abnormal connection between arteries and veins, bypassing the capillary system. This vascular anomaly is widely known because of its occurrence in the central nervous system (usually cerebral AVM), but can appear in any location. Although many AVMs are asymptomatic, they can cause intense pain or bleeding or lead to other serious medical problems. AVMs are usually congenital and belong to the RASopathies. The genetic transmission patterns of AVMs are incomplete, but there are known genetic mutations (for instance in the epithelial line, tumor suppressor PTEN gene) which can lead to an increased occurrence throughout the body. Signs and symptoms Symptoms of AVM vary according to the location of the malformation. Roughly 88% of people with an AVM are asymptomatic; often the malformation is discovered as part of an autopsy or during treatment of an unrelated disorder (called in medicine an "incidental finding"); in rare cases, its expansion or a micro-bleed from an AVM in the brain can cause epilepsy, neurological deficit, or pain. The most general symptoms of a cerebral AVM include headaches and epileptic seizures, with more specific symptoms occurring that normally depend on the location of the malformation and the individual. Such possible symptoms include: Difficulties with movement coordination, including muscle weakness and even paralysis; Vertigo (dizziness); Difficulties of speech (dysarthria) and communication, such as aphasia; Difficulties with everyday activities, such as apraxia; Abnormal sensations (numbness, tingling, or spontaneous pain); Memory and thought-related problems, such as confusion, dementia or hallucinations. Cerebral AVMs may present themselves in a number of different ways: Bleeding (45% of cases) Acute onset of severe headache. May be described as the worst headache of the patient's life. Depending on the location of bleeding, may be associated with new fixed neurologic deficit. In unruptured brain AVMs, the risk of spontaneous bleeding may be as low as 1% per year. After a first rupture, the annual bleeding risk may increase to more than 5%. Seizure or brain seizure (46%) Depending on the place of the AVM, it can cause loss of vision in one place. Headache (34%) Progressive neurologic deficit (21%) May be caused by mass effect or venous dilatations. Presence and nature of the deficit depend on location of lesion and the draining veins. Pediatric patients Heart failure Macrocephaly Prominent scalp veins Pulmonary arteriovenous malformations Pulmonary arteriovenous malformations are abnormal communications between the veins and arteries of the pulmonary circulation, leading to a right-to-left blood shunt. They have no symptoms in up to 29% of all cases, however they can give rise to serious complications including hemorrhage, and infection. They are most commonly associated with hereditary hemorrhagic telangiectasia. Genetics Can occur due to autosomal dominant diseases, such as hereditary hemorrhagic telangiectasia. Pathophysiology Arteries and veins are part of the vascular system. Arteries carry blood away from the heart to the lungs or the rest of the body, where the blood passes through capillaries, and veins return the blood to the heart. An AVM interferes with this process by forming a direct connection of the arteries and veins. AVMs can cause intense pain and lead to serious medical problems. Although AVMs are often associated with the brain and spinal cord, they can develop in any part of the body. Normally, the arteries in the vascular system carry oxygen-rich blood, except in the case of the pulmonary artery. Structurally, arteries divide and sub-divide repeatedly, eventually forming a sponge-like capillary bed. Blood moves through the capillaries, giving up oxygen and taking up waste products, including , from the surrounding cells. Capillaries in turn successively join together to form veins that carry blood away. The heart acts to pump blood through arteries and uptake the venous blood. As an AVM lacks the dampening effect of capillaries on the blood flow, the AVM can get progressively larger over time as the amount of blood flowing through it increases, forcing the heart to work harder to keep up with the extra blood flow. It also causes the surrounding area to be deprived of the functions of the capillaries—removal of and delivery of nutrients to the cells. The resulting tangle of blood vessels, often called a nidus (Latin for "nest"), has no capillaries. It can be extremely fragile and prone to bleeding because of the abnormally direct connections between high-pressure arteries and low-pressure veins. The resultant sign, audible via stethoscope, is a rhythmic, whooshing sound caused by excessively rapid blood flow through the arteries and veins. It has been given the term "bruit", French for noise. On some occasions, a patient with a brain AVM may become aware of the noise, which can compromise hearing and interfere with sleep in addition to causing psychological distress. Diagnosis AVMs are diagnosed primarily by the following imaging methods: Computerized tomography (CT) scan is a noninvasive X-ray to view the anatomical structures within the brain to detect blood in or around the brain. A newer technology called CT angiography involves the injection of contrast into the blood stream to view the arteries of the brain. This type of test provides the best pictures of blood vessels through angiography and soft tissues through CT. Magnetic resonance imaging (MRI) scan is a noninvasive test, which uses a magnetic field and radio-frequency waves to give a detailed view of the soft tissues of the brain. Magnetic resonance angiography (MRA) – scans created using magnetic resonance imaging to specifically image the blood vessels and structures of the brain. A magnetic resonance angiogram can be an invasive procedure, involving the introduction of contrast dyes (e.g., gadolinium MR contrast agents) into the vasculature of a patient using a catheter inserted into an artery and passed through the blood vessels to the brain. Once the catheter is in place, the contrast dye is injected into the bloodstream and the MR images are taken. Additionally or alternatively, flow-dependent or other contrast-free magnetic resonance imaging techniques can be used to determine the location and other properties of the vasculature. AVMs can occur in various parts of the body: brain (cerebral AV malformation) spleen lung kidney spinal cord liver intercostal space iris spermatic cord extremities – arm, shoulder, etc. AVMs may occur in isolation or as a part of another disease (for example, Von Hippel-Lindau disease or hereditary hemorrhagic telangiectasia). AVMs have been shown to be associated with aortic stenosis. Bleeding from an AVM can be relatively mild or devastating. It can cause severe and less often fatal strokes. If a cerebral AVM is detected before a stroke occurs, usually the arteries feeding blood into the nidus can be closed off to avert the danger. However, interventional therapy may also be relatively risky. Treatment Treatment for brain AVMs can be symptomatic, and patients should be followed by a neurologist for any seizures, headaches, or focal neurologic deficits. AVM-specific treatment may also involve endovascular embolization, neurosurgery or radiosurgery. Embolization, that is, cutting off the blood supply to the AVM with coils, particles, acrylates, or polymers introduced by a radiographically guided catheter, may be used in addition to neurosurgery or radiosurgery, but is rarely successful in isolation except in smaller AVMs. Gamma knife may also be used. Treatment of lung AVMs is typically performed with endovascular embolization alone, which is considered the standard of care. Epidemiology The estimated detection rate of AVM in the US general population is 1.4/100,000 per year. This is approximately one fifth to one seventh the incidence of intracranial aneurysms. An estimated 300,000 Americans have AVMs, of whom 12% (approximately 36,000) will exhibit symptoms of greatly varying severity. History Luschka (1820–1875) and Virchow (1821–1902) first described arteriovenous malformations in the mid-1800s. Olivecrona (1891–1980) performed the first surgical excision of an intracranial AVM in 1932. Society and culture Notable cases Indonesian actress died from complications of AVM on November 29, 2013. Phoenix Suns point guard AJ Price nearly died from AVM in 2004 while a student at the University of Connecticut. On December 13, 2006, Senator Tim Johnson of South Dakota was diagnosed with AVM and treated at George Washington University Hospital. On August 3, 2011, Mike Patterson of the Philadelphia Eagles collapsed on the field and suffered a seizure during a practice, leading to him being diagnosed with AVM. Actor Ricardo Montalbán was born with spinal AVM. During the filming of the 1951 film Across the Wide Missouri, Montalbán was thrown from his horse, knocked unconscious, and trampled by another horse which aggravated his AVM and resulted in a painful back injury that never healed. The pain increased as he aged, and in 1993, Montalbán underwent 9½ hours of spinal surgery which left him paralyzed below the waist and using a wheelchair. Actor/comedian T. J. Miller was diagnosed with AVM after filming Yogi Bear in New Zealand in 2010; Miller described his experience with the disease on the Pete Holmes podcast You Made It Weird on October 28, 2011, shedding his comedian side for a moment and becoming more philosophical, narrating his behaviors and inability to sleep during that time. He suffered a seizure upon return to Los Angeles and successfully underwent surgery that had a mortality rate of ten percent. Jazz guitarist Pat Martino experienced an AVM and subsequently developed amnesia and manic depression. He eventually re-learned to play the guitar by listening to his own recordings from before the aneurysm. YouTube vlogger Nikki Lilly (Nikki Christou), winner of the 2016 season of Junior Bake Off was born with AVM, which has resulted in some facial disfigurement. Composer and lyricist William Finn was diagnosed with AVM and underwent Gamma Knife surgery in September 1992, soon after he won the 1992 Tony Award for best musical, awarded to "Falsettos". Finn wrote the 1998 Off-Broadway musical A New Brain about the experience. Former Florida Gators and Oakland Raiders linebacker Neiron Ball was diagnosed with AVM in 2011 while playing for Florida, but recovered and was cleared to play. On September 16, 2018, Ball was placed in a medically induced coma due to complications of the disease, which lasted until his death on September 10, 2019. Country music singer Drake White was diagnosed with AVM in January 2019, and is undergoing treatment. Cultural Depictions In the HBO series Six Feet Under (TV series), main character Nate Fisher discovers he has an AVM after being in a car accident and getting a precautionary cat scan at the hospital during Season 1. His AVM becomes a key focus during Season 2 and again in Season 5. Research Despite many years of research, the central question of whether to treat AVMs has not been answered. All treatments, whether involving surgery, radiation, or drugs, have risks and side-effects. Therefore, it might be better in some cases to avoid treatment altogether and simply accept a small risk of coming to harm from the AVM itself. This question is currently being addressed in clinical trials.

Atlanta

Atlanta ( ) is the capital and most populous city of the U.S. state of Georgia. With a 2020 census population of 498,715, it is the eighth-most populous city in the Southeast and 38th most populous city in the United States. It serves as the cultural and economic center of the Atlanta metropolitan area, home to more than six million people and the ninth-largest metropolitan area in the nation. It is the seat of Fulton County, the most populous county in Georgia. Situated among the foothills of the Appalachian Mountains, it features unique topography that includes rolling hills and the most dense urban tree coverage in the United States. Atlanta was originally founded as the terminus of a major state-sponsored railroad. With rapid expansion, however, it soon became the convergence point among multiple railroads, spurring its rapid growth. Its name derives from that of the Western and Atlantic Railroad's local depot, signifying its growing reputation as a transportation hub. Toward the end of the American Civil War, in November 1864, most of the city was burned to the ground in General William T. Sherman's March to the Sea. However, it was rehabilitated and quickly became a national center of commerce and the unofficial capital of the "New South". During the 1950s and 1960s, it became a major organizing center of the civil rights movement, with Martin Luther King Jr., Ralph David Abernathy, and many other locals playing major roles in the movement's leadership. During the modern era, it has attained international prominence as a major air transportation hub, with Hartsfield–Jackson Atlanta International Airport being the world's busiest airport by passenger traffic since 1998. With a gross domestic product (GDP) of $406 billion, Atlanta has the 10th largest economy in the U.S. and the 20th largest in the world. Its economy is considered diverse, with dominant sectors that include aerospace, transportation, logistics, film and television production, media operations, professional and business services, medical services, and information technology. The gentrification of some its neighborhoods, initially spurred by the 1996 Summer Olympics, has intensified in the 21st century with the growth of the Atlanta Beltline. This has altered its demographics, politics, aesthetics, and culture. History Native American settlements For thousands of years prior to the arrival of European settlers in north Georgia, the indigenous Creek people and their ancestors inhabited the area. Standing Peachtree, a Creek village where Peachtree Creek flows into the Chattahoochee River, was the closest Native American settlement to what is now Atlanta. Through the early 19th century, European Americans systematically encroached on the Creek of northern Georgia, forcing them out of the area from 1802 to 1825. The Creek were forced to leave the area in 1821, under Indian Removal by the federal government, and European American settlers arrived the following year. Western and Atlantic Railroad In 1836, the Georgia General Assembly voted to build the Western and Atlantic Railroad in order to provide a link between the port of Savannah and the Midwest. The initial route was to run southward from Chattanooga to a terminus east of the Chattahoochee River, which would be linked to Savannah. After engineers surveyed various possible locations for the terminus, the "zero milepost" was driven into the ground in what is now Foundry Street, Five Points. When asked in 1837 about the future of the little village, Stephen H.Long, the railroad's chief engineer said the place would be good "for one tavern, a blacksmith shop, a grocery store, and nothing else". A year later, the area around the milepost had developed into a settlement, first known as Terminus, and later Thrasherville, after a local merchant who built homes and a general store in the area. By 1842, the town had six buildings and 30 residents and was renamed Marthasville to honor Governor Wilson Lumpkin's daughter Martha. Later, John Edgar Thomson, Chief Engineer of the Georgia Railroad, suggested the town be renamed Atlanta. The residents approved, and the town was incorporated as Atlanta on December 29, 1847. Civil War By 1860, Atlanta's population had grown to 9,554. During the American Civil War, the nexus of multiple railroads in Atlanta made the city a strategic hub for the distribution of military supplies. In 1864, the Union Army moved southward following the capture of Chattanooga and began its invasion of north Georgia. The region surrounding Atlanta was the location of several major army battles, culminating with the Battle of Atlanta and a four-month-long siege of the city by the Union Army under the command of General William Tecumseh Sherman. On September 1, 1864, Confederate General John Bell Hood decided to retreat from Atlanta, and he ordered the destruction of all public buildings and possible assets that could be of use to the Union Army. On the next day, Mayor James Calhoun surrendered Atlanta to the Union Army, and on September 7, Sherman ordered the city's civilian population to evacuate. On November 11, 1864, Sherman prepared for the Union Army's March to the Sea by ordering the destruction of Atlanta's remaining military assets. Reconstruction and late 19th century After the Civil War ended in 1865, Atlanta was gradually rebuilt during the Reconstruction era. The work attracted many new residents. Due to the city's superior rail transportation network, the state capital was moved from Milledgeville to Atlanta in 1868. In the 1880 Census, Atlanta had surpassed Savannah as Georgia's largest city. Beginning in the 1880s, Henry W. Grady, the editor of the Atlanta Constitution newspaper, promoted Atlanta to potential investors as a city of the "New South" that would be based upon a modern economy and less reliant on agriculture. By 1885, the founding of the Georgia School of Technology (now Georgia Tech) and the Atlanta University Center, a consortium of historically black colleges made up of units for men and women, had established Atlanta as a center for higher education. In 1895, Atlanta hosted the Cotton States and International Exposition, which attracted nearly 800,000 attendees and successfully promoted the New South's development to the world. 20th century During the first decades of the 20th century, Atlanta enjoyed a period of unprecedented growth. In three decades' time, Atlanta's population tripled as the city limits expanded to include nearby streetcar suburbs. The city's skyline grew taller with the construction of the Equitable, Flatiron, Empire, and Candler buildings. Sweet Auburn emerged as a center of black commerce. The period was also marked by strife and tragedy. Increased racial tensions led to the Atlanta Race Riot of 1906, when whites attacked blacks, leaving at least 27 people dead and over 70 injured, with extensive damage in black neighborhoods. In 1913, Leo Frank, a Jewish-American factory superintendent, was convicted of the murder of a 13-year-old girl in a highly publicized trial. He was sentenced to death but the governor commuted his sentence to life. An enraged and organized lynch mob took him from jail in 1915 and hanged him in Marietta. The Jewish community in Atlanta and across the country were horrified. On May 21, 1917, the Great Atlanta Fire destroyed 1,938 buildings in what is now the Old Fourth Ward, resulting in one fatality and the displacement of 10,000 people. On December 15, 1939, Atlanta hosted the premiere of Gone with the Wind, the epic film based on the best-selling novel by Atlanta's Margaret Mitchell. The gala event at Loew's Grand Theatre was attended by the film's legendary producer, David O. Selznick, and the film's stars Clark Gable, Vivien Leigh, and Olivia de Havilland, but Oscar winner Hattie McDaniel, an African-American actress, was barred from the event due to racial segregation laws. Metropolitan area's growth Atlanta played a vital role in the Allied effort during World War II due to the city's war-related manufacturing companies, railroad network and military bases. The defense industries attracted thousands of new residents and generated revenues, resulting in rapid population and economic growth. In the 1950s, the city's newly constructed highway system, supported by federal subsidies, allowed middle class Atlantans the ability to relocate to the suburbs. As a result, the city began to make up an ever-smaller proportion of the metropolitan area's population. Georgia Tech's president Blake R Van Leer played an important role with a goal of making Atlanta the "MIT of the South." In 1946 Georgia Tech secured about $240,000 () annually in sponsored research and purchased an electron microscope for $13,000 (), the first such instrument in the Southeastern United States and one of few in the United States at the time. The Research Building was expanded, and a $300,000 () Westinghouse A-C network calculator was given to Georgia Tech by Georgia Power in 1947. In 1953, Van Leer assisted with helping Lockheed establish a research and development and production line in Marietta. Later in 1955 he helped set up a committee to assist with establishing a nuclear research facility, which would later become the Neely Nuclear Research Center. Van Leer also co-founded Southern Polytechnic State University now absorbed by and made part of Kennesaw State University to help meet the need for technicians after the war. Van Leer was instrumental in making the school and Atlanta the first major research center in the American South. The building that houses Tech's school of Electrical and Computer Engineering bears his name. Civil Rights Movement African-American veterans returned from World War II seeking full rights in their country and began heightened activism. In exchange for support by that portion of the black community that could vote, in 1948 the mayor ordered the hiring of the first eight African-American police officers in the city. Much controversy preceded the 1956 Sugar Bowl, when the Pitt Panthers, with African-American fullback Bobby Grier on the roster, met the Georgia Tech Yellow Jackets. There had been controversy over whether Grier should be allowed to play due to his race, and whether Georgia Tech should even play at all due to Georgia's Governor Marvin Griffin's opposition to racial integration. After Griffin publicly sent a telegram to the state's Board of Regents requesting Georgia Tech not to engage in racially integrated events, Georgia Tech's president Blake R Van Leer rejected the request and threatened to resign. The game went on as planned. In the 1960s, Atlanta became a major organizing center of the civil rights movement, with Martin Luther King Jr., Ralph David Abernathy, and students from Atlanta's historically black colleges and universities playing major roles in the movement's leadership. While Atlanta in the postwar years had relatively minimal racial strife compared to other cities, blacks were limited by discrimination, segregation, and continued disenfranchisement of most voters. In 1961, the city attempted to thwart blockbusting by realtors by erecting road barriers in Cascade Heights, countering the efforts of civic and business leaders to foster Atlanta as the "city too busy to hate". Desegregation of the public sphere came in stages, with public transportation desegregated by 1959, the restaurant at Rich's department store by 1961, movie theaters by 1963, and public schools by 1973 (nearly 20 years after the US Supreme Court ruled that segregated public schools were unconstitutional). In 1960, whites comprised 61.7% of the city's population. During the 1950s–70s, suburbanization and white flight from urban areas led to a significant demographic shift. By 1970, African Americans were the majority of the city's population and exercised their recently enforced voting rights and political influence by electing Atlanta's first black mayor, Maynard Jackson, in 1973. Under Mayor Jackson's tenure, Atlanta's airport was modernized, strengthening the city's role as a transportation center. The opening of the Georgia World Congress Center in 1976 heralded Atlanta's rise as a convention city. Construction of the city's subway system began in 1975, with rail service commencing in 1979. Despite these improvements, Atlanta lost more than 100,000 residents between 1970 and 1990, over 20% of its population. At the same time, it developed new office space after attracting numerous corporations, with an increasing portion of workers from northern areas. 1996 Summer Olympic Games Atlanta was selected as the site for the 1996 Summer Olympic Games. Following the announcement, the city government undertook several major construction projects to improve Atlanta's parks, sporting venues, and transportation infrastructure; however, for the first time, none of the $1.7 billion cost of the games was governmentally funded. While the games experienced transportation and accommodation problems and, despite extra security precautions, there was the Centennial Olympic Park bombing, the spectacle was a watershed event in Atlanta's history. For the first time in Olympic history, every one of the record 197 national Olympic committees invited to compete sent athletes, sending more than 10,000 contestants participating in a record 271 events. The related projects such as Atlanta's Olympic Legacy Program and civic effort initiated a fundamental transformation of the city in the following decade. 2000 to present During the 2000s, Atlanta underwent a profound physical, cultural, and demographic transformation. As some of the black middle and upper classes also began to move to the suburbs, a booming economy drew numerous new migrants from other areas of the country, who contributed to changes in the city's demographics. African Americans made up a decreasing portion of the population, from a high of 67% in 1990 to 54% in 2010. From 2000 to 2010, Atlanta gained 22,763 white residents, 5,142 Asian residents, and 3,095 Hispanic residents, while the city's black population decreased by 31,678. Much of the city's demographic change during the decade was driven by young, college-educated professionals: from 2000 to 2009, the three-mile radius surrounding Downtown Atlanta gained 9,722 residents aged 25 to 34 and holding at least a four-year degree, an increase of 61%. This was similar to the tendency in other cities for young, college educated, single or married couples to live in downtown areas. Between the mid-1990s and 2010, stimulated by funding from the HOPE VI program and under leadership of CEO Renee Lewis Glover (1994–2013), the Atlanta Housing Authority demolished nearly all of its public housing, a total of 17,000 units and about 10% of all housing units in the city. After reserving 2,000 units mostly for elderly, the AHA allowed redevelopment of the sites for mixed-use and mixed-income, higher density developments, with 40% of the units to be reserved for affordable housing. Two-fifths of previous public housing residents attained new housing in such units; the remainder received vouchers to be used at other units, including in suburbs. At the same time, in an effort to change the culture of those receiving subsidized housing, the AHA imposed a requirement for such residents to work (or be enrolled in a genuine, limited-time training program). It is virtually the only housing authority to have created this requirement. To prevent problems, the AHA also gave authority to management of the mixed-income or voucher units to evict tenants who did not comply with the work requirement or who caused behavior problems. In 2005, the city approved the $2.8 billion BeltLine project. It was intended to convert a disused 22-mile freight railroad loop that surrounds the central city into an art-filled multi-use trail and light rail transit line, which would increase the city's park space by 40%. The project stimulated retail and residential development along the loop, but has been criticised for its adverse effects on some Black communities. In 2013, the project received a federal grant of $18 million to develop the southwest corridor. In September 2019 the James M. Cox Foundation gave $6 Million to the PATH Foundation which will connect the Silver Comet Trail to The Atlanta BeltLine which is expected to be completed by 2022. Upon completion, the total combined interconnected trail distance around Atlanta for The Atlanta BeltLine and Silver Comet Trail will be the longest paved trail surface in the U.S. totaling about . Atlanta's cultural offerings expanded during the 2000s: the High Museum of Art doubled in size; the Alliance Theatre won a Tony Award; and art galleries were established on the once-industrial Westside. The city of Atlanta was the subject of a massive cyberattack which began in March 2018. Geography Atlanta encompasses , of which is land and is water. The city is situated among the foothills of the Appalachian Mountains. At above mean sea level, Atlanta has the highest elevation among major cities east of the Mississippi River. Atlanta straddles the Eastern Continental Divide. Rainwater that falls on the south and east side of the divide flows into the Atlantic Ocean, while rainwater on the north and west side of the divide flows into the Gulf of Mexico. Atlanta developed on a ridge south of the Chattahoochee River, which is part of the ACF River Basin. The river borders the far northwestern edge of the city, and much of its natural habitat has been preserved, in part by the Chattahoochee River National Recreation Area. Atlanta is sometimes called "City of Trees" or "city in a forest", despite having lost approximately of trees between 1973 and 1999. Cityscape File:Atlanta-Panorama.jpg Most of Atlanta was burned during the Civil War, depleting the city of a large stock of its historic architecture. Yet architecturally, the city had never been traditionally "southern" because Atlanta originated as a railroad town, rather than a southern seaport dominated by the planter class, such as Savannah or Charleston. Because of its later development, many of the city's landmarks share architectural characteristics with buildings in the Northeast or Midwest, as they were designed at a time of shared national architectural styles. During the late 20th century, Atlanta embraced the global trend of modern architecture, especially for commercial and institutional structures. Examples include the State of Georgia Building built in 1966, and the Georgia-Pacific Tower in 1982. Many of the most notable examples from this period were designed by world renowned Atlanta architect John Portman. Most of the buildings that define the downtown skyline were designed by Portman during this period, including the Westin Peachtree Plaza and the Atlanta Marriott Marquis. In the latter half of the 1980s, Atlanta became one of the early homes of postmodern buildings that reintroduced classical elements to their designs. Many of Atlanta's tallest skyscrapers were built in this period and style, displaying tapering spires or otherwise ornamented crowns, such as One Atlantic Center (1987), 191 Peachtree Tower (1991), and the Four Seasons Hotel Atlanta (1992). Also completed during the era is the Portman-designed Bank of America Plaza built in 1992. At , it is the tallest building in the city and the 14th-tallest in the United States. The city's embrace of modern architecture has often translated into an ambivalent approach toward historic preservation, leading to the destruction of many notable architectural landmarks. These include the Equitable Building (1892–1971), Terminal Station (1905–1972), and the Carnegie Library (1902–1977). In the mid-1970s, the Fox Theatre, now a cultural icon of the city, would have met the same fate if not for a grassroots effort to save it. More recently, preservationists may have made some inroads. For example, in 2016 activists convinced the Atlanta City Council not to demolish the Atlanta-Fulton Central Library, the last building designed by noted architect Marcel Breuer. Atlanta is divided into 242 officially defined neighborhoods. The city contains three major high-rise districts, which form a north–south axis along Peachtree: Downtown, Midtown, and Buckhead. Surrounding these high-density districts are leafy, low-density neighborhoods, most of which are dominated by single-family homes. Downtown Atlanta contains the most office space in the metro area, much of it occupied by government entities. Downtown is home to the city's sporting venues and many of its tourist attractions. Midtown Atlanta is the city's second-largest business district, containing the offices of many of the region's law firms. Midtown is known for its art institutions, cultural attractions, institutions of higher education, and dense form. Buckhead, the city's uptown district, is north of Downtown and the city's third-largest business district. The district is marked by an urbanized core along Peachtree Road, surrounded by suburban single-family neighborhoods situated among woods and rolling hills. Surrounding Atlanta's three high-rise districts are the city's low- and medium-density neighborhoods, where the craftsman bungalow single-family home is dominant. The eastside is marked by historic streetcar suburbs, built from the 1890s–1930s as havens for the upper middle class. These neighborhoods, many of which contain their own villages encircled by shaded, architecturally distinct residential streets, include the Victorian Inman Park, Bohemian East Atlanta, and eclectic Old Fourth Ward. On the westside and along the BeltLine on the eastside, former warehouses and factories have been converted into housing, retail space, and art galleries, transforming the once-industrial areas such as West Midtown into model neighborhoods for smart growth, historic rehabilitation, and infill construction. In southwest Atlanta, neighborhoods closer to downtown originated as streetcar suburbs, including the historic West End, while those farther from downtown retain a postwar suburban layout. These include Collier Heights and Cascade Heights, home to much of the city's affluent African-American population. Northwest Atlanta contains the areas of the city to west of Marietta Boulevard and to the north of Martin Luther King, Jr. Drive, including those neighborhoods remote to downtown, such as Riverside, Bolton and Whittier Mill. The latter is one of Atlanta's designated Landmark Historical Neighborhoods. Vine City, though technically Northwest, adjoins the city's Downtown area and has recently been the target of community outreach programs and economic development initiatives. Gentrification of the city's neighborhoods is one of the more controversial and transformative forces shaping contemporary Atlanta. The gentrification of Atlanta has its origins in the 1970s, after many of Atlanta's neighborhoods had declined and suffered the urban decay that affected other major American cities in the mid-20th century. When neighborhood opposition successfully prevented two freeways from being built through the city's east side in 1975, the area became the starting point for Atlanta's gentrification. After Atlanta was awarded the Olympic games in 1990, gentrification expanded into other parts of the city, stimulated by infrastructure improvements undertaken in preparation for the games. New development post-2000 has been aided by the Atlanta Housing Authority's eradication of the city's public housing. As noted above, it allowed development of these sites for mixed-income housing, requiring developers to reserve a considerable portion for affordable housing units. It has also provided for other former residents to be given vouchers to gain housing in other areas. Construction of the Beltline has stimulated new and related development along its path. Climate Under the Köppen classification, Atlanta has a humid subtropical climate (Cfa) with four distinct seasons and generous precipitation year-round, typical for the Upland South; the city is situated in USDA Plant Hardiness Zone 8a, with the northern and western suburbs, as well as part of Midtown transitioning to 7b. Summers are hot and humid, with temperatures somewhat moderated by the city's elevation. Winters are cool but variable, occasionally susceptible to snowstorms even if in small quantities on several occasions, unlike the central and southern portions of the state. Warm air from the Gulf of Mexico can bring spring-like highs while strong Arctic air masses can push lows into the teens °F (−7 to −12 °C). July averages , with high temperatures reaching on an average of 47 days per year, though readings are not seen most years. January averages , with temperatures in the suburbs slightly cooler due largely to the urban heat island effect. Lows at or below freezing can be expected 36 nights annually, but the last occurrence of temperatures below is January 6, 2014. Extremes range from on February 13, 1899 to on June 30, 2012. Average dewpoints in the summer range from in June to in July. Typical of the southeastern U.S., Atlanta receives abundant rainfall that is evenly distributed throughout the year, though late spring and early fall are somewhat drier. The average annual precipitation is , while snowfall is typically light with a normal of per winter. The heaviest single snowfall occurred on January 23, 1940, with around of snow. However, ice storms usually cause more problems than snowfall does, the most severe occurring on January 7, 1973. Tornadoes are rare in the city itself, but the March 14, 2008 EF2 tornado damaged prominent structures in downtown Atlanta. The coldest temperature recorded in Atlanta was on January 21, 1985 when it reached a temperature of . Demographics Population The 2020 United States census reported that Atlanta had a population of 498,715. The population density was 3,685.45 persons per square mile (1,422.95/km2). The racial makeup and population of Atlanta was 51.0% Black or African American, 40.9% White, 4.2% Asian and 0.3% Native American, and 1.0% from other races. 2.4% of the population reported two or more races. Hispanics of any race made up 6.0% of the city's population. The median income for a household in the city was $45,171. The per capita income for the city was $35,453. 22.6% percent of the population was living below the poverty line. In the 1920s, the black population began to grow in Southern metropolitan cities like Atlanta, Birmingham, Houston, and Memphis. In the 2010 Census, Atlanta was recorded as the nation's fourth-largest majority-black city. The New Great Migration brought an insurgence of African Americans from California and the North to the Atlanta area. It has long been known as a center of African-American political power, education, economic prosperity, and culture, often called a black mecca. Some middle and upper class African-American residents of Atlanta followed an influx of whites to newer housing and public schools in the suburbs in the early 21st century. From 2000 to 2010, the city's black population decreased by 31,678 people, shrinking from 61.4% of the city's population in 2000 to 54.0% in 2010, as the overall population expanded and migrants increased from other areas. At the same time, the white population of Atlanta has increased. Between 2000 and 2010, the proportion of whites in the city had notable growth. In that decade, Atlanta's white population grew from 31% to 38% of the city's population, an absolute increase of 22,753 people, more than triple the increase that occurred between 1990 and 2000. Early immigrants in the Atlanta area were mostly Jews and Greeks. Since 1970, the Hispanic immigrant population, especially Mexicans, has experienced the most rapid growth, particularly in Gwinnett, Cobb, and DeKalb counties. Since 2010, the Atlanta area has seen very notable growth with immigrants from India, China, South Korea, and Jamaica. Other notable countries immigrants come from are Vietnam, Eritrea, Nigeria, the Arabian gulf, Ukraine and Poland. Within a few decades, and in keeping with national trends, immigrants from England, Ireland, and German-speaking central Europe were no longer the majority of Atlanta's foreign-born population. The city's Italians included immigrants from northern Italy, many of whom had been in Atlanta since the 1890s; more recent arrivals from southern Italy; and Sephardic Jews from the Isle of Rhodes, which Italy had seized from Turkey in 1912. Of the total population five years and older, 83.3% spoke only English at home, while 8.8% spoke Spanish, 3.9% another Indo-European language, and 2.8% an Asian language. 7.3% of Atlantans were born abroad (86th in the US). Atlanta's dialect has traditionally been a variation of Southern American English. The Chattahoochee River long formed a border between the Coastal Southern and Southern Appalachian dialects. Because of the development of corporate headquarters in the region, attracting migrants from other areas of the country, by 2003, Atlanta magazine concluded that Atlanta had become significantly "de-Southernized". A Southern accent was considered a handicap in some circumstances. In general, Southern accents are less prevalent among residents of the city and inner suburbs and among younger people; they are more common in the outer suburbs and among older people. At the same time, some residents of the city speak in Southern variations of African-American English. Religion in Atlanta, while historically centered on Protestant Christianity, now encompasses many faiths, as a result of the city and metro area's increasingly international population. Some 63% of residents identify as some type of Protestant, but in recent decades the Catholic Church has increased in numbers and influence because of new migrants to the region. Metro Atlanta also has numerous ethnic or national Christian congregations, including Korean and Indian churches. The larger non-Christian faiths are Judaism, Islam, and Hinduism. Overall, there are over 1,000 places of worship within Atlanta. Sexual orientation and gender identity Atlanta has a thriving and diverse lesbian, gay, bisexual, and transgender (LGBT) community. According to a 2006 survey by the Williams Institute, Atlanta ranked third among major American cities, behind San Francisco and slightly behind Seattle, with 12.8% of the city's total population identifying as LGBT. The Midtown and Cheshire Bridge areas have historically been the epicenters of LGBT culture in Atlanta. Atlanta formed a reputation for being a progressive place of tolerance after former mayor Ivan Allen Jr. dubbed it "the city too busy to hate" in the 1960s. Economy With a GDP of $385 billion, the Atlanta metropolitan area's economy is the 10th-largest in the country and among the 20-largest in the world. Corporate operations play a major role in Atlanta's economy, as the city claims the nation's third-largest concentration of Fortune 500 companies. It also hosts the global headquarters of several corporations such as The Coca-Cola Company, The Home Depot, Delta Air Lines, AT&T Mobility, Chick-fil-A, and UPS. Over 75% of Fortune 1000 companies conduct business operations in the city's metro area, and the region hosts offices of over 1,250 multinational corporations. Many corporations are drawn to the city by its educated workforce; , 45% of adults aged 25 or older residing in the city have at least four-year college degrees, compared to the national average of 28%. Atlanta started as a railroad town, and logistics has been a major component of the city's economy to this day. Atlanta serves as an important rail junction and contains major classification yards for Norfolk Southern and CSX. Since its construction in the 1950s, Hartsfield–Jackson Atlanta International Airport has served as a key engine of the city's economic growth. Delta Air Lines, the city's largest employer and the metro area's third-largest, operates the world's largest airline hub at Hartsfield-Jackson, and it has helped make it the world's busiest airport, in terms of both passenger traffic and aircraft operations. Partly due to the airport, Atlanta has been also a hub for diplomatic missions; , the city contains 26 consulates general, the seventh-highest concentration of diplomatic missions in the US. Broadcasting is also an important aspect of Atlanta's economy. In the 1980s, media mogul Ted Turner founded the Cable News Network (CNN) and the Turner Broadcasting System (TBS) in the city. Around the same time, Cox Enterprises, now the nation's third-largest cable television service and the publisher of over a dozen American newspapers, moved its headquarters to the city. The Weather Channel is also based just outside of the city in suburban Cobb County. Information technology (IT) has become an increasingly important part of Atlanta's economic output, earning the city the nickname the "Silicon peach". , Atlanta contains the fourth-largest concentration of IT jobs in the US, numbering 85,000+. The city is also ranked as the sixth fastest-growing for IT jobs, with an employment growth of 4.8% in 2012 and a three-year growth near 9%, or 16,000 jobs. Companies are drawn to Atlanta's lower costs and educated workforce. Recently, Atlanta has been the center for film and television production, largely because of the Georgia Entertainment Industry Investment Act, which awards qualified productions a transferable income tax credit of 20% of all in-state costs for film and television investments of $500,000 or more. Film and television production facilities based in Atlanta include Turner Studios, Pinewood Atlanta Studios, Tyler Perry Studios, Williams Street Productions, and the EUE/Screen Gems soundstages. Film and television production injected $9.5 billion into Georgia's economy in 2017, with Atlanta garnering most of the projects. Atlanta has emerged as the all-time most popular destination for film production in the United States and one of the 10 most popular destinations globally. Compared to other American cities, Atlanta's economy in the past had been disproportionately affected by the 2008 financial crisis and the subsequent recession, with the city's economy being ranked 68th among 100 American cities in a September 2014 report due to an elevated unemployment rate, declining real income levels, and a depressed housing market. From 2010 to 2011, Atlanta saw a 0.9% contraction in employment and plateauing income growth at 0.4%. Although unemployment had decreased to 7% by late 2014, this was still higher than the national unemployment rate of 5.8% Atlanta's housing market has also struggled, with home prices dropping by 2.1% in January 2012, reaching levels not seen since 1996. Compared with a year earlier, the average home price in Atlanta plummeted to 17.3% in February 2012, thus becoming the largest annual drop in the history of the index for any American or global city. The decline in home prices prompted some economists to deem Atlanta the worst housing market in the nation at the height of the depression. Nevertheless, the city's real estate market has resurged since 2012, so much median home value and rent growth significantly outpaced the national average by 2018, thanks to a rapidly-growing regional economy. Culture Atlanta is noted for its lack of Southern culture. This is due to a large population of migrants from other parts of the U.S., in addition to many recent immigrants to the U.S. who have made the metropolitan area their home, establishing Atlanta as the cultural and economic hub of an increasingly multi-cultural metropolitan area. Thus, although traditional Southern culture is part of Atlanta's cultural fabric, it is mostly a footnote to one of the nation's most cosmopolitan cities. This unique cultural combination reveals itself in the arts district of Midtown, the quirky neighborhoods on the city's eastside, and the multi-ethnic enclaves found along Buford Highway. Arts and theater Atlanta is one of few United States cities with permanent, professional, and resident companies in all major performing arts disciplines: opera (Atlanta Opera), ballet (Atlanta Ballet), orchestral music (Atlanta Symphony Orchestra), and theater (the Alliance Theatre). Atlanta attracts many touring Broadway acts, concerts, shows, and exhibitions catering to a variety of interests. Atlanta's performing arts district is concentrated in Midtown Atlanta at the Woodruff Arts Center, which is home to the Atlanta Symphony Orchestra and the Alliance Theatre. The city frequently hosts touring Broadway acts, especially at The Fox Theatre, a historic landmark among the highest-grossing theaters of its size. As a national center for the arts, Atlanta is home to significant art museums and institutions. The renowned High Museum of Art is arguably the South's leading art museum. The Museum of Design Atlanta (MODA) and the SCAD FASH Museum of Fashion + Film are the only such museums in the Southeast. Contemporary art museums include the Atlanta Contemporary Art Center and the Museum of Contemporary Art of Georgia. Institutions of higher education contribute to Atlanta's art scene, with the Savannah College of Art and Design's Atlanta campus providing the city's arts community with a steady stream of curators, and Emory University's Michael C. Carlos Museum containing the largest collection of ancient art in the Southeast. In nearby Athens is the Georgia Museum of Art that is associated with the University of Georgia and is both an academic museum and the official art museum of the state of Georgia. Atlanta has become one of the USA's best cities for street art in recent years. It is home to Living Walls, an annual street art conference and the Outerspace Project, an annual event series that merges public art, live music, design, action sports, and culture. Examples of street art in Atlanta can be found on the Atlanta Street Art Map. Music Atlanta has played a major or contributing role in the development of various genres of American music at different points in the city's history. Beginning as early as the 1920s, Atlanta emerged as a center for country music, which was brought to the city by migrants from Appalachia. During the countercultural 1960s, Atlanta hosted the Atlanta International Pop Festival, with the 1969 festival taking place more than a month before Woodstock and featuring many of the same bands. The city was also a center for Southern rock during its 1970s heyday: the Allman Brothers Band's hit instrumental "Hot 'Lanta" is an ode to the city, while Lynyrd Skynyrd's famous live rendition of "Free Bird" was recorded at the Fox Theatre in 1976, with lead singer Ronnie Van Zant directing the band to "play it pretty for Atlanta". During the 1980s, Atlanta had an active punk rock scene centered on two of the city's music venues, 688 Club and the Metroplex, and Atlanta famously played host to the Sex Pistols' first U.S. show, which was performed at the Great Southeastern Music Hall. The 1990s saw the city produce major mainstream acts across many different musical genres. Country music artist Travis Tritt, and R&B sensations Xscape, TLC, Usher and Toni Braxton, were just some of the musicians who call Atlanta home. The city also gave birth to Atlanta hip hop, a subgenre that gained relevance and success with the introduction of the home-grown Atlantans known as Outkast, along with other Dungeon Family artists such as Organized Noize and Goodie Mob; however, it was not until the 2000s that Atlanta moved "from the margins to becoming hip-hop's center of gravity with another sub-genre called Crunk, part of a larger shift in hip-hop innovation to the South and East". Also in the 2000s, Atlanta was recognized by the Brooklyn-based Vice magazine for its indie rock scene, which revolves around the various live music venues found on the city's alternative eastside. To facilitate further local development, the state government provides qualified businesses and productions a 15% transferable income tax credit for in-state costs of music investments. Trap music became popular in Atlanta, and has since become a hub for popular trap artists and producers due to the success of T.I., Young Jeezy, 21 Savage, Gucci Mane, Future, Migos, Lil Yachty, Playboi Carti, 2 Chainz and Young Thug. Film and television As the national leader for motion picture and television production, and a top ten global leader, Atlanta plays a significant role in the entertainment industry. Atlanta is considered a hub for filmmakers of color and houses Tyler Perry Studios (first African-American owned major studio) and Areu Bros. Studios (first Latino-American owned major studio). Atlanta doubles for other parts of the world and fictional settlements in blockbuster productions, among them the newer titles from The Fast and the Furious franchise and Marvel features such as Ant-Man (2015), Captain America: Civil War (2016), Black Panther and Avengers: Infinity War (both 2018). On the other hand, Gone With the Wind (1939), Smokey and the Bandit (1977), Sharkey's Machine (1981), The Slugger's Wife (1985), Driving Miss Daisy (1989), ATL (2006), and Baby Driver (2017) are among several notable examples of films actually set in Atlanta. The city also provides the backdrop for shows such as Ozark, Watchmen, The Walking Dead, Stranger Things, Love is Blind, Star, Dolly Parton's Heartstrings, The Outsider, The Vampire Diaries and Atlanta, in addition to a myriad of animated and reality television programming. Festivals Atlanta has more festivals than any city in the southeastern United States. Some notable festivals in Atlanta include Shaky Knees Music Festival, Dragon Con, the Peachtree Road Race, Music Midtown, the Atlanta Film Festival, National Black Arts Festival, Honda Battle of the Bands, Festival Peachtree Latino, Atlanta Pride, the neighborhood festivals in Inman Park, Atkins Park, Virginia-Highland (Summerfest), and the Little Five Points Halloween festival. Tourism , Atlanta is the seventh-most visited city in the United States, with over 35 million visitors per year. Although the most popular attraction among visitors to Atlanta is the Georgia Aquarium, the world's largest indoor aquarium, Atlanta's tourism industry is mostly driven by the city's history museums and outdoor attractions. Atlanta contains a notable number of historical museums and sites, including the Martin Luther King Jr. National Historical Park, which includes the preserved childhood home of Dr. Martin Luther King Jr., as well as his final resting place; the Atlanta Cyclorama & Civil War Museum, which houses a massive painting and diorama in-the-round, with a rotating central audience platform, depicting the Battle of Atlanta in the Civil War; the World of Coca-Cola, featuring the history of the world-famous soft drink brand and its well-known advertising; the College Football Hall of Fame, which honors college football and its athletes; the National Center for Civil and Human Rights, which explores the civil rights movement and its connection to contemporary human rights movements throughout the world; the Carter Center and Presidential Library, housing U.S. President Jimmy Carter's papers and other material relating to the Carter administration and the Carter family's life; and the Margaret Mitchell House and Museum, where Mitchell wrote the best-selling novel Gone with the Wind. Atlanta contains several outdoor attractions. The Atlanta Botanical Garden, adjacent to Piedmont Park, is home to the Kendeda Canopy Walk, a skywalk that allows visitors to tour one of the city's last remaining urban forests from above the ground. The Canopy Walk is considered the only canopy-level pathway of its kind in the United States. Zoo Atlanta, in Grant Park, accommodates over 1,300 animals representing more than 220 species. Home to the nation's largest collections of gorillas and orangutans, the zoo is one of only four zoos in the U.S. to house giant pandas. Festivals showcasing arts and crafts, film, and music, including the Atlanta Dogwood Festival, the Atlanta Film Festival, and Music Midtown, respectively, are also popular with tourists. Tourists are drawn to the city's culinary scene, which comprises a mix of urban establishments garnering national attention, ethnic restaurants serving cuisine from every corner of the world, and traditional eateries specializing in Southern dining. Since the turn of the 21st century, Atlanta has emerged as a sophisticated restaurant town. Many restaurants opened in the city's gentrifying neighborhoods have received praise at the national level, including Bocado, Bacchanalia, and Miller Union in West Midtown, Empire State South in Midtown, and Two Urban Licks and Rathbun's on the east side. In 2011, The New York Times characterized Empire State South and Miller Union as reflecting "a new kind of sophisticated Southern sensibility centered on the farm but experienced in the city". Visitors seeking to sample international Atlanta are directed to Buford Highway, the city's international corridor, and suburban Gwinnett County. There, the nearly-million immigrants that make Atlanta home have established various authentic ethnic restaurants representing virtually every nationality on the globe. For traditional Southern fare, one of the city's most famous establishments is The Varsity, a long-lived fast food chain and the world's largest drive-in restaurant. Mary Mac's Tea Room and Paschal's are more formal destinations for Southern food. Sports Sports are an important part of the culture of Atlanta. The city is home to professional franchises for four major team sports: the Atlanta Braves of Major League Baseball, the Atlanta Hawks of the National Basketball Association, the Atlanta Falcons of the National Football League, and Atlanta United FC of Major League Soccer. In addition, many of the city's universities participate in collegiate sports. The city also regularly hosts international, professional, and collegiate sporting events. The Braves moved to Atlanta in 1966. Originally established as the Boston Red Stockings in 1871, they are the oldest continually operating professional sports franchise in the United States. The Atlanta Braves won the World Series in 1995 and 2021. The 1995 title occurred during an unprecedented run of 14 straight divisional championships from 1991 to 2005. The team plays at Truist Park, having moved from Turner Field for the 2017 season. The new stadium is outside the city limits, located northwest of downtown in the Cumberland/Galleria area of Cobb County. The Atlanta Falcons have played in Atlanta since their inception in 1966. The team play their home games at Mercedes Benz Stadium, having moved from the Georgia Dome in 2017. The Falcons have won the division title six times (1980, 1998, 2004, 2010, 2012, 2016) and the NFC championship twice in 1998 and 2016. They have been unsuccessful in both of their Super Bowl trips, losing to the Denver Broncos in Super Bowl XXXIII in 1999 and to the New England Patriots in Super Bowl LI in 2017, the largest comeback in Super Bowl history. In 2019, Atlanta also briefly hosted an Alliance of American Football team, the Atlanta Legends, but the league was suspended during its first season and the team folded. The Atlanta Hawks were founded in 1946 as the Tri-Cities Blackhawks, playing in Moline, Illinois. They moved to Atlanta from St. Louis in 1968 and play their games in State Farm Arena. The Atlanta Dream of the Women's National Basketball Association shared an arena with the Hawks for most of their existence; however the WNBA team moved to a smaller arena in the southern Atlanta suburb of College Park in 2021. Professional soccer has been played in some form in Atlanta since 1967. Atlanta's first professional soccer team was the Atlanta Chiefs of the original North American Soccer League which won the 1968 NASL Championship and defeated English first division club Manchester City F.C. twice in international friendlies. In 1998 the Atlanta Silverbacks were formed, playing the new North American Soccer League. They now play as an amateur club in the National Premier Soccer League. In 2017, Atlanta United FC began play as Atlanta's first premier-division professional soccer club since the Chiefs. They won MLS Cup 2018, defeating the Portland Timbers 2–0. Fan reception has been very positive; the team has broken several single-game and season attendance records for both MLS and the U.S. Open Cup. The club is estimated by Forbes to be the most valuable club in Major League Soccer. In ice hockey, Atlanta has had two National Hockey League franchises, both of which relocated to a city in Canada after playing in Atlanta for fewer than 15 years. The Atlanta Flames (now the Calgary Flames) played from 1972 to 1980, and the Atlanta Thrashers (now the Winnipeg Jets) played from 1999 to 2011. The Atlanta Gladiators, a minor league hockey team in the ECHL, have played in the Atlanta suburb of Duluth since 2003. The ASUN Conference moved its headquarters to Atlanta in 2019. Several other, less popular sports also have professional franchises in Atlanta. The Georgia Swarm compete in the National Lacrosse League. In Rugby union, on September 21, 2018, Major League Rugby announced that Atlanta was one of the expansion teams joining the league for the 2020 season named Rugby ATL. whilst in Rugby league, on 31 March 2021, Atlanta Rhinos left the USA Rugby League and turned fully professional for the first time, joining the new North American Rugby League On August 2, 2018, it was announced that Atlanta would have its own Overwatch League team, Atlanta Reign. Atlanta has long been known as the "capital" of college football in America. Also, Atlanta is within a few hours driving distance of many of the universities that make up the Southeastern Conference, college football's most profitable and popular conference, and annually hosts the SEC Championship Game. Other annual college football events include the Chick-fil-A Kickoff Game, the Celebration Bowl, the MEAC/SWAC Challenge, and the Chick-fil-A Peach Bowl which is one of College Football's major New Year's Six Bowl games and a college football playoff bowl. Atlanta additionally hosted the 2018 College Football Playoff National Championship. Atlanta regularly hosts a variety of sporting events. Most famous was the Centennial 1996 Summer Olympics. The city has hosted the super bowl three times: Super Bowl XXVIII in 1994, Super Bowl XXXIV in 2000, and Super Bowl LIII in 2019.

The city hosts the Peachtree Road Race, the world's largest race, annually on Independence Day. Atlanta also hosts the nation's largest Thanksgiving day half marathon, which starts and ends at Georgia State Stadium. The Atlanta Marathon, which starts and ends at Centennial Olympic Park, routes through many of the city's historic landmarks, and its 2020 running will coincide with the U.S. Olympic marathon trials for the 2020 Summer Olympics. Parks and recreation Atlanta's 343 parks, nature preserves, and gardens cover , which amounts to only 5.6% of the city's total acreage, compared to the national average of just over 10%. However, 64% of Atlantans live within a 10-minute walk of a park, a percentage equal to the national average. In its 2013 ParkScore ranking, The Trust for Public Land reported that among the park systems of the 50 most populous U.S. cities, Atlanta's park system received a ranking of 31. Piedmont Park, in Midtown, is Atlanta's most iconic green space. The park, which underwent a major renovation and expansion in recent years, attracts visitors from across the region and hosts cultural events throughout the year. Other notable city parks include Centennial Olympic Park, a legacy of the 1996 Summer Olympics that forms the centerpiece of the city's tourist district; Woodruff Park, which anchors the campus of Georgia State University; Grant Park, home to Zoo Atlanta; Chastain Park, which houses an amphitheater used for live music concerts; and the under construction Westside Park at Bellwood Quarry, the 280-acre green space and reservoir project slated to become the city's largest park when fully complete in the 2020s. The Chattahoochee River National Recreation Area, in the northwestern corner of the city, preserves a stretch of the river for public recreation opportunities. The Atlanta Botanical Garden, adjacent to Piedmont Park, contains formal gardens, including a Japanese garden and a rose garden, woodland areas, and a conservatory that includes indoor exhibits of plants from tropical rainforests and deserts. The BeltLine, a former rail corridor that forms a loop around Atlanta's core, has been transformed into a series of parks, connected by a multi-use trail, increasing Atlanta's park space by 40%. Atlanta offers resources and opportunities for amateur and participatory sports and recreation. Golf and tennis are popular in Atlanta, and the city contains six public golf courses and 182 tennis courts. Facilities along the Chattahoochee River cater to watersports enthusiasts, providing the opportunity for kayaking, canoeing, fishing, boating, or tubing. The city's only skate park, a facility that offers bowls, curbs, and smooth-rolling concrete mounds, is at Historic Fourth Ward Park. Government Atlanta is governed by a mayor and the 15-member Atlanta City Council. The city council consists of one member from each of the city's 12 districts and three at-large members. The mayor may veto a bill passed by the council, but the council can override the veto with a two-thirds majority. The mayor of Atlanta is Andre Dickens, a Democrat elected on a nonpartisan ballot whose first term in office began on January 3, 2022. Every mayor elected since 1973 has been black. In 2001, Shirley Franklin became the first woman to be elected mayor of Atlanta, and the first African-American woman to serve as mayor of a major Southern city. Atlanta city politics suffered from a notorious reputation for corruption during the 1990s administration of Mayor Bill Campbell, who was convicted by a federal jury in 2006 on three counts of tax evasion in connection with gambling winnings during trips he took with city contractors. As the state capital, Atlanta is the site of most of Georgia's state government. The Georgia State Capitol building, located downtown, houses the offices of the governor, lieutenant governor and secretary of state, as well as the General Assembly. The Governor's Mansion is in a residential section of Buckhead. Atlanta serves as the regional hub for many arms of the federal bureaucracy, including the Federal Reserve Bank of Atlanta and the Centers for Disease Control and Prevention (CDC). The City of Atlanta annexed the CDC into its territory effective January 1, 2018. Atlanta also plays an important role in the federal judiciary system, containing the United States Court of Appeals for the Eleventh Circuit and the United States District Court for the Northern District of Georgia. Historically, Atlanta has been a stronghold for the Democratic Party. Although municipal elections are officially nonpartisan, nearly all of the city's elected officials are registered Democrats. The city is split among 14 state house districts and four state senate districts, all held by Democrats. At the federal level, Atlanta is split between three congressional districts. Most of the city is in the 5th district, represented by Democrat Nikema Williams. Much of southern Atlanta is in the 13th district, represented by Democrat David Scott. A small portion in the north is in the 11th district, represented by Republican Barry Loudermilk. Law enforcement, fire, and EMS services The city is served by the Atlanta Police Department, which numbers 2,000 officers and oversaw a 40% decrease in the city's crime rate between 2001 and 2009. Specifically, homicide decreased by 57%, rape by 72%, and violent crime overall by 55%. Crime is down across the country, but Atlanta's improvement has occurred at more than twice the national rate. Nevertheless, Forbes ranked Atlanta as the sixth most dangerous city in the United States in 2012. Aggravated assaults, burglaries and robberies were down from 2014. Mexican drug cartels thrive in Atlanta. 145 gangs operate in Atlanta. The Atlanta Fire Rescue Department provides fire protection and first responder emergency medical services to the city from its 35 fire stations. In 2017, AFRD responded to over 100,000 calls for service over a coverage area of . The department also protects Hartsfield–Jackson with 5 fire stations on the property; serving over 1 million passengers from over 100 different countries. The department protects over 3000 high-rise buildings, of the rapid rail system, and of interstate highway. Emergency ambulance services are provided to city residents by hospital based Grady EMS (Fulton County), and American Medical Response (DeKalb County). Atlanta in January 2017 declared the city was a "welcoming city" and "will remain open and welcoming to all". Nonetheless, Atlanta does not consider itself to be a "sanctuary city". Atlanta Mayor Keisha Lance Bottoms said: "Our city does not support ICE. We don't have a relationship with the U.S. Marshal[s] Service. We closed our detention center to ICE detainees, and we would not pick up people on an immigration violation." Education Tertiary education Due to more than 15 colleges and universities in Atlanta, it is considered one of the nation's largest hubs for higher education. The Georgia Institute of Technology is a prominent public research university in Midtown. It offers highly ranked degree programs in engineering, design, industrial management, the sciences, and architecture. Georgia State University is a major public research university in Downtown Atlanta; it is the largest in student population of the 29 public colleges and universities in the University System of Georgia and is a significant contributor to the revitalization of the city's central business district. Atlanta is home to nationally renowned private colleges and universities, most notably Emory University, a leading liberal arts and research institution that operates Emory Healthcare, the largest health care system in Georgia. The City of Atlanta annexed Emory into its territory effective January 1, 2018. The Atlanta University Center is also in the city; it is the oldest and largest contiguous consortium of historically black colleges in the nation, comprising Spelman College, Clark Atlanta University, Morehouse College, and Morehouse School of Medicine. Atlanta contains a campus of the Savannah College of Art and Design, a private art and design university that has proven to be a major factor in the recent growth of Atlanta's visual art community. Atlanta also boast American Bar Association accredited law schools: Atlanta's John Marshall Law School, Emory University School of Law, and Georgia State University College of Law. The Atlanta Regional Council of Higher Education (ARCHE) is dedicated to strengthening synergy among 19 public and private colleges and universities in the Atlanta region. Participating Atlanta region colleges and universities partner on joint-degree programs, cross-registration, library services, and cultural events. The University of Georgia's Terry College of Business has a satellite campus in the Buckhead region of Atlanta, one of the main financial hubs for the city. This campus is primarily for part-time MBA and executive education programs. Primary and secondary education Fifty-five thousand students are enrolled in 106 schools in Atlanta Public Schools (APS), some of which are operated as charter schools. Atlanta is served by many private schools including, without limitation, Atlanta Jewish Academy, Atlanta International School, The Westminster Schools, Pace Academy, The Lovett School, The Paideia School, Holy Innocents' Episcopal School and Roman Catholic parochial schools operated by the Archdiocese of Atlanta. In 2018 the City of Atlanta annexed a portion of DeKalb County containing the Centers for Disease Control and Emory University; this portion will be zoned to the DeKalb County School District until 2024, when it will transition into APS. In 2017 the number of children living in the annexed territory who attended public schools was nine. Media The primary network-affiliated television stations in Atlanta are WXIA-TV 11 (NBC), WGCL-TV 46 (CBS), WSB-TV 2 (ABC), and WAGA-TV 5 (Fox). Other major commercial stations include WPXA-TV 14 (Ion), WPCH-TV 17 (Ind.), WUVG-TV 34 (Univision/UniMás), WUPA 69 (CW), and WATL 36 (MyNetworkTV). WPXA-TV, WUVG-TV, WAGA-TV and WUPA are network O&O's. The Atlanta metropolitan area is served by two public television stations (both PBS member stations), and two public radio stations. WGTV 8 is the flagship station of the statewide Georgia Public Television network, while WABE-TV is owned by Atlanta Public Schools. Georgia Public Radio is listener-funded and comprises one NPR member station, WABE, a classical music station also operated by Atlanta Public Schools. The second public radio, listener-funded NPR member station is WCLK, a jazz music station owned and operated by Clark Atlanta University. Atlanta is served by The Atlanta Journal-Constitution, its only major daily newspaper with wide distribution. The Atlanta Journal-Constitution is the result of a 1950 merger between The Atlanta Journal and The Atlanta Constitution, with staff consolidation occurring in 1982 and separate publication of the morning Constitution and afternoon Journal ceasing in 2001. Alternative weekly newspapers include Creative Loafing, which has a weekly print circulation of 80,000. Atlanta magazine is a monthly general-interest magazine based in and covering Atlanta. Transportation Atlanta's transportation infrastructure comprises a complex network that includes a heavy rail rapid transit system, a light rail streetcar loop, a multi-county bus system, Amtrak service via the Crescent, multiple freight train lines, an Interstate Highway System, several airports, including the world's busiest, and over of bike paths. Atlanta has a network of freeways that radiate out from the city, and automobiles are the dominant means of transportation in the region. Three major interstate highways converge in Atlanta: I-20 (east-west), I-75 (northwest-southeast), and I-85 (northeast-southwest). The latter two combine in the middle of the city to form the Downtown Connector (I-75/85), which carries more than 340,000 vehicles per day and is one of the most congested segments of interstate highway in the United States. Atlanta is mostly encircled by Interstate 285, a beltway locally known as "the Perimeter" that has come to mark the boundary between "Inside the Perimeter" (ITP), the city and close-in suburbs, and "Outside the Perimeter" (OTP), the outer suburbs and exurbs. The heavy reliance on automobiles for transportation in Atlanta has resulted in traffic, commute, and air pollution rates that rank among the worst in the country. The City of Atlanta has a higher than average percentage of households without a car. In 2015, 15.2 percent of Atlanta households lacked a car, and increased slightly to 16.4 percent in 2016. The national average is 8.7 percent in 2016. Atlanta averaged 1.31 cars per household in 2016, compared to a national average of 1.8. The Metropolitan Atlanta Rapid Transit Authority (MARTA) provides public transportation in the form of buses, heavy rail, and a downtown light rail loop. Notwithstanding heavy automotive usage in Atlanta, the city's subway system is the eighth busiest in the country. MARTA rail lines connect key destinations, such as the airport, Downtown, Midtown, Buckhead, and Perimeter Center. However, significant destinations, such as Emory University and Cumberland, remain unserved. As a result, a 2011 Brookings Institution study placed Atlanta 91st of 100 metro areas for transit accessibility. Emory University operates its Cliff shuttle buses with 200,000 boardings per month, while private minibuses supply Buford Highway. Amtrak, the national rail passenger system, provides service to Atlanta via the Crescent train (New York–New Orleans), which stops at Peachtree Station. In 2014, the Atlanta Streetcar opened to the public. The streetcar's line, which is also known as the Downtown Loop, runs around the downtown tourist areas of Peachtree Center, Centennial Olympic Park, the Martin Luther King Jr. National Historical Park, and Sweet Auburn. The Atlanta Streetcar line is also being expanded on in the coming years to include a wider range of Atlanta's neighborhoods and important places of interest, with a total of over of track in the plan. Hartsfield–Jackson Atlanta International Airport is the world's busiest airport as measured by passenger traffic and aircraft traffic. The facility offers air service to over 150 U.S. destinations and more than 75 international destinations in 50 countries, with over 2,500 arrivals and departures daily. Delta Air Lines maintains its largest hub at the airport. Situated () south of downtown, the airport covers most of the land inside a wedge formed by Interstate 75, Interstate 85, and Interstate 285. Cycling is a growing mode of transportation in Atlanta, more than doubling since 2009, when it comprised 1.1% of all commutes (up from 0.3% in 2000). Although Atlanta's lack of bike lanes and hilly topography may deter many residents from cycling, the city's transportation plan calls for the construction of of bike lanes by 2020, with the BeltLine helping to achieve this goal. In 2012, Atlanta's first "bike track" was constructed on 10th Street in Midtown. The two lane bike track runs from Monroe Drive west to Charles Allen Drive, with connections to the Beltline and Piedmont Park. Starting in June 2016, Atlanta received a bike sharing program, known as Relay Bike Share, with 100 bikes in Downtown and Midtown, which expanded to 500 bikes at 65 stations as of April 2017. According to the 2016 American Community Survey (five-year average), 68.6% of working city of Atlanta residents commuted by driving alone, 7% carpooled, 10% used public transportation, and 4.6% walked. About 2.1% used all other forms of transportation, including taxi, bicycle, and motorcycle. About 7.6% worked at home. The city has also become one of a handful of "scooter capitals", where companies like Lime and Bird have gained a major foothold by placing electric scooters on street corners and byways. Tree canopy Atlanta has a reputation as a "city in a forest" due to an abundance of trees that is rare among major cities. The city's main street is named after a tree, and beyond the Downtown, Midtown, and Buckhead business districts, the skyline gives way to a dense canopy of woods that spreads into the suburbs. The city is home to the Atlanta Dogwood Festival, an annual arts and crafts festival held one weekend during early April, when the native dogwoods are in bloom. The nickname is factually accurate, as vegetation covers 47.9% of the city as of 2017, the highest among all major American cities, and well above the national average of 27%. Atlanta's tree coverage does not go unnoticed—it was the main reason cited by National Geographic in naming Atlanta a "Place of a Lifetime". The city's lush tree canopy, which filters out pollutants and cools sidewalks and buildings, has increasingly been under assault from man and nature due to heavy rains, drought, aged forests, new pests, and urban construction. A 2001 study found Atlanta's heavy tree cover declined from 48% in 1974 to 38% in 1996. Community organizations and the city government are addressing the problem. Trees Atlanta, a non-profit organization founded in 1985, has planted and distributed over 113,000 shade trees in the city, and Atlanta's government has awarded $130,000 in grants to neighborhood groups to plant trees. Fees are additionally imposed on developers that remove trees on their property per a citywide ordinance, active since 1993.

Axiology

Axiology (from Greek , axia: "value, worth"; and , -logia: "study of") is the philosophical study of value. It includes questions about the nature and classification of values and about what kinds of things have value. It is intimately connected with various other philosophical fields that crucially depend on the notion of value, like ethics, aesthetics or philosophy of religion. It is also closely related to value theory and meta-ethics. The term was first used by Paul Lapie, in 1902, and Eduard von Hartmann, in 1908. The distinction between intrinsic and extrinsic value is central to axiology. One conceptualization holds that something is intrinsically valuable if it is good in itself or good for its own sake. It is usually held that intrinsic value depends on certain features of the valuable entity. For example, an experience may be said to be intrinsically valuable in virtue of being pleasurable. Extrinsic value, by contrast, is ascribed to things that are valuable only as a means to something else. Substantive theories of value try to determine which entities have intrinsic value. Monist theories hold that there is only one type of intrinsic value. The paradigm example of monist theories is hedonism, the thesis that only pleasure has intrinsic value. Pluralist theories, on the other hand, contend that there are various different types of intrinsic value, for example, virtue, knowledge, friendship, etc. Value pluralists face the problem of explaining whether or how the different types of value can be compared when making rational decisions. Some philosophers state that values do not exist on the most fundamental level of reality. One such view holds that a value statement about something just expresses the speaker's approval or disapproval of this thing. This position is opposed by realists about value. History Between the 5th and 6th centuries BC, it was important in Greece to be knowledgeable if you were to be successful. Philosophers began to recognize that differences existed between the laws and morality of society. Socrates believed that knowledge had a vital connection to virtue, making morality and democracy closely intertwined. Socrates' student, Plato furthered the belief by establishing virtues which should be followed by all. E. J. Dijksterhuis found that axiological antithesis characterized the philosophy of ancient Greece: With the fall of the government, values became individual, causing skeptic schools of thought to flourish, ultimately shaping an ontologically objective philosophy that is thought to have contributed to Christian Philosophy. During the medieval period, Thomas Aquinas made the distinction between natural and supernatural (theological) virtues. This concept led philosophers to distinguish between judgments based on fact and judgments based on values, creating the division between science and philosophy. Intrinsic value Traditionally, philosophers held that an entity has intrinsic value if it is good in itself or good for its own sake. Intrinsic value is contrasted with extrinsic or instrumental value, which is ascribed to things that are valuable only as a means to something else. For example, tools like cars or microwaves are said to be extrinsically valuable by virtue of the function they perform, while the well-being they cause is intrinsically valuable, according to hedonism. The same entity can be valuable in different ways: some entities have both intrinsic and extrinsic values at the same time. Extrinsic values can form chains, in which one entity is extrinsically valuable because it is a means to another entity that is itself extrinsically valuable. It is commonly held that these chains must terminate somewhere and that the endpoint can only be intrinsically valuable. The distinction between intrinsic and extrinsic values is important for understanding various disagreements within axiology. Different substantive theories of value often agree on whether something, for example knowledge, is valuable while disagreeing on whether the value in question is intrinsic or extrinsic. The traditional conception of intrinsic value presented above has been criticized in contemporary philosophy on the grounds that it combines various distinct notions that are better discussed separately. One such contrast is between intrinsic and final values. On a more narrow conception, an intrinsic value is a value an entity has in virtue of its intrinsic properties. For example, assuming that the phenomenal aspect of a pleasant experience is an intrinsic property, we might say that the experience is intrinsically valuable because of this intrinsic property. An entity with final value, by contrast, is valuable for its own sake. It is usually accepted that there is a conceptual difference between intrinsic and final values. For example, the pleasure experience may be said to be intrinsically valuable on the one hand, and finally valuable on the other hand. But it has been disputed whether there are actual things where these value types can come apart. Proposed candidates for bearers of final non-intrinsic value include unique or rare items (e.g. a stamp) or historically significant items (e.g. the pen that Abraham Lincoln used to sign the Emancipation Proclamation). Being-rare and having-been-used-by-someone are extrinsic properties that may be responsible for their bearers having final value, i.e. being valuable for their own sake. Some philosophers have questioned whether extrinsic values should be regarded as values at all rather than as mere indications of values. One reason for considering this idea is that adding or removing extrinsically valuable things does not affect the value of the whole if all intrinsically valuable things are kept constant. For example, the 2011 Tōhoku earthquake had a negative extrinsic value because of all the damage it caused. But arguably, the world would not have been a better place if exactly the same damage had been caused without the earthquake. Ontological status of values In axiology, it is often important to distinguish between the entity that is valuable and the features in virtue of which it is valuable. For example, an experience may be said to be valuable in virtue of being pleasurable. This distinction is particularly relevant for intrinsic values since it is commonly held that the intrinsic value of an entity supervenes on its intrinsic features. This means that the entity could not have a different intrinsic value unless it had different intrinsic features. Substantive theories of value focus on the features in virtue of which something has intrinsic value. Popular candidates for these features include pleasure, virtue and knowledge. Another question concerns the nature of the entities that are the bearers of value. The main approaches to this question can be divided into the Kantian tradition, which considers concrete things like persons to be the bearers of value, and the Moorean tradition, which holds that only states of affairs bear value. This difference is important when determining whether a value is extrinsic or intrinsic to an entity. Some philosophers hold that objects like Napoleon's hat are valuable because of their relation to extraordinary persons. From a Kantian perspective, this value must be extrinsic since it is based on the extrinsic property of having been worn by an extraordinary person. But from a Moorean perspective, it can be intrinsic since it is born not by the hat but by a state of affairs involving both the hat and Napoleon. The preceding discussion about the ontological categories of values and value-bearers assumes some form of realism: that there actually are valuable things. But the difficulties in reaching expert consensus in value-related fields like ethics, aesthetics or politics and considerations from naturalism have led various philosophers to doubt this assumption. The ensuing dispute between cognitivists and non-cognitivists is usually held on the level of value-statements or value-attitudes, either concerning all values or specifically concerning ethical values. Cognitivists assert that value-statements are truth-apt, i.e. are either true or false, which is denied by non-cognitivists. Most cognitivists are realists about values: they believe that values are part of reality. Error theory, as originally articulated by J. L. Mackie, is an exception. Error theorists hold that all value-statements are false, and thereby truth-apt, because the world lacks value-features that would be needed to make them true. Non-cognitivists, on the other hand, go one step further by denying that value-statements are truth-apt. This position involves the difficulty of explaining how value-statements can be meaningful despite lacking a truth value. This challenge can be met in different ways. Emotivists, following A. J. Ayer, state that value-statements only express the emotions of the speaker and are intended to influence the actions of the listener. Prescriptivism, as developed by R. M. Hare, interprets value-statements as imperatives or commands. Simon Blackburn's quasi-realism states that value statements project emotional attitudes as though they were real properties. Monism and pluralism Substantive theories of value try to determine which entities have intrinsic value. A traditional dispute in this field is between monist and pluralist theories. According to Chris Heathwood, monism and pluralism can be distinguished according to an evaluation of what is good in people and the concept of "value simpliciter" in terms of intrinsic value. Monist theories hold that there is only one type of intrinsic value. The paradigm example of monist theories is hedonism, the thesis that only pleasure has intrinsic value. Pluralist theories, on the other hand, contend that there are various different types of intrinsic value. They maintain that these types of intrinsic values cannot be reduced to a single feature of an act or entity. W. D. Ross, for example, holds that pleasure is only one type of intrinsic value besides other types, like knowledge. It is important to keep in mind that this disagreement only concerns intrinsic value, not value at large. So hedonists may be happy to concede that knowledge is valuable, but only extrinsically so, given that knowledge can be helpful in causing pleasure and avoiding pain. Various arguments have been suggested in the monism-pluralism-dispute. Common-sense seems to favor value pluralism: values are ascribed to a wide range of different things like happiness, liberty, friendship, etc. without any obvious common feature underlying these values. One way to defend value monism is to cast doubt on the reliability of common-sense for technical matters like the distinction between intrinsic and extrinsic value. This strategy is pursued by J. J. C. Smart, who holds that there is a psychological bias to mistake stable extrinsic values for intrinsic values. Value pluralists have often attempted to provide exhaustive lists of all value types, but different theorists have suggested very different lists. These lists seem to constitute arbitrary selections unless a clear criterion could be provided why all and only these items are included. But if a criterion was to be found then such a theory would no longer be pluralistic. This dilemma suggests that pluralism is inadequate as an explanation. One issue closely related to the monism-pluralism-debate is the problem of incommensurability: the question of whether there are incommensurable values. Two values are incommensurable if there is no fact as to whether one is better than or as good as the other: there is no common value scale according to which they could be compared. According to Joseph Raz, career choices between very different paths, for example, whether to become a lawyer or a clarinetist, are cases where incommensurable values are involved. Value pluralists often assert that values belonging to different types are incommensurable with each other. Value monists, by contrast, usually deny that there are incommensurable values. This question is particularly relevant for ethics. If different options available to the agent embody incommensurable values then there seems to be no rational way to determine what ought to be done since there is no matter of fact as to which option is better. Widespread incommensurability would threaten to undermine the practical relevance of ethics and rational choice. Other concepts and distinctions Many evaluative terms are found in everyday language, often with various different meanings. It is important for philosophers to distinguish these different meanings in order to avoid misunderstandings. One such distinction is between a predicative and an attributive sense of good and bad. In the attributive sense, an entity is good in relation to a certain kind. For example, a person with a clear voice may be a good singer or a knife with a blunt edge may be a bad knife. But this still leaves it open whether the entity in question is good or bad in an unqualified or predicative sense. For example, a person may be a bad assassin but being bad as an assassin is not bad in a predicative sense. Axiology is usually interested in the predicative sense of goodness. But some philosophers deny that such a sense exists and therefore hold that all value is relative to a kind. A second important distinction is that between being good for a person and being good for the world. Being good for a person or prudential value has to do with this person's welfare or well-being. But what is good for one person may be bad for another person. For example, having a dry summer may be good for the hiker in virtue of the pleasant hiking conditions, but bad for the farmer, whose crop is dying because of a lack of water. In such cases, the question arises as to what is good for the world or good simpliciter. Utilitarians can solve this problem by defining the good for the world as the sum of the good for each persons. Philosophers often distinguish between evaluative concepts (like good or bad) and deontic concepts (like right, fitting or ought). The former belong to axiology proper and express what has worth or value while the latter belong to ethics (and related fields) and express what one ought to do. Philosophers have tried to provide a unified account of these two fields since they seem to be intimately related. Consequentialists see evaluative concepts as fundamental and define deontic concepts in terms of evaluative concepts. Fitting-attitude theories, on the other hand, try to reduce evaluative concepts to deontic concepts. Consequentialism is an ethical theory that holds that, given a certain set of possible actions, we ought to perform the action that has the best overall consequences. So what we ought to do is defined in evaluative terms: whatever leads to the consequences with the highest value. Fitting-attitude theories are axiological theories that define the value of something in terms of the attitude that would be fitting to have towards this thing, for example, that it would be good to find a cure for cancer because this would be a fitting object of desire. These accounts build on the deontic notion that some of our attitudes towards the world are fitting or right to define what is good.

A Doll's House

A Doll's House (Danish and ; also translated as A Doll House) is a three-act play written by Norwegian playwright Henrik Ibsen. It premiered at the Royal Theatre in Copenhagen, Denmark, on 21 December 1879, having been published earlier that month. The play is set in a Norwegian town circa 1879. The play is significant for the way it deals with the fate of a married woman, who at the time in Norway lacked reasonable opportunities for self-fulfillment in a male-dominated world, despite the fact that Ibsen denied it was his intent to write a feminist play. It aroused a great sensation at the time, and caused a "storm of outraged controversy" that went beyond the theatre to the world of newspapers and society. In 2006, the centennial of Ibsen's death, A Doll's House held the distinction of being the world's most performed play that year. UNESCO has inscribed Ibsen's autographed manuscripts of A Doll's House on the Memory of the World Register in 2001, in recognition of their historical value. The title of the play is most commonly translated as A Doll's House, though some scholars use A Doll House. John Simon says that A Doll's House is "the British term for what [Americans] call a 'dollhouse'". Egil Törnqvist says of the alternative title: "Rather than being superior to the traditional rendering, it simply sounds more idiomatic to Americans." List of characters Nora Helmer – wife of Torvald, mother of three, is living out the ideal of the 19th-century wife, but leaves her family at the end of the play. Torvald Helmer – Nora's husband, a newly promoted bank manager, professes to be enamoured of his wife but their marriage stifles her. Dr. Rank – a rich family friend. He is terminally ill, and it is implied that his "tuberculosis of the spine" originates from a venereal disease contracted by his father. Kristine Linde – Nora's old school friend, widowed, is seeking employment (sometimes spelled Christine in English translations). She was in a relationship with Krogstad prior to the play's setting. Nils Krogstad – an employee at Torvald's bank, single father, he is pushed to desperation. A supposed scoundrel, he is revealed to be a long-lost lover of Kristine. The Children – Nora and Torvald's children: Ivar, Bobby and Emmy (in order of age). Anne Marie – Nora's former nanny, who gave up her own daughter to "strangers" when she became, as she says, the only mother Nora knew. She now cares for Nora's children. Helene – the Helmers' maid The Porter – delivers a Christmas tree to the Helmer household at the beginning of the play. Synopsis Act One The play opens at Christmas time as Nora Helmer enters her home carrying many packages. Nora's husband Torvald is working in his study when she arrives. He playfully rebukes her for spending so much money on Christmas gifts, calling her his "little squirrel." He teases her about how the previous year she had spent weeks making gifts and ornaments by hand because money was scarce. This year Torvald is due a promotion at the bank where he works, so Nora feels that they can let themselves go a little. The maid announces two visitors: Mrs. Kristine Linde, an old friend of Nora's, who has come seeking employment; and Dr. Rank, a close friend of the family, who is let into the study. Kristine has had a difficult few years, ever since her husband died leaving her with no money or children. Nora says that things have not been easy for them either: Torvald became sick, and they had to travel to Italy so he could recover. Kristine explains that when her mother was ill she had to take care of her brothers, but now that they are grown she feels her life is "unspeakably empty." Nora promises to talk to Torvald about finding her a job. Kristine gently tells Nora that she is like a child. Nora is offended, so she teases the idea that she got money from "some admirer" so they could travel to Italy to improve Torvald's health. She told Torvald that her father gave her the money, but in fact she illegally borrowed it without his knowledge (women were forbidden from conducting financial activities such as signing checks without a man's endorsement). Since then, she has been secretly working and saving up to pay off the loan. Krogstad, a lower-level employee at Torvald's bank, arrives and goes into the study. Nora is clearly uneasy when she sees him. Dr. Rank leaves the study and mentions that he feels wretched, though like everyone he wants to go on living. In contrast to his physical illness, he says that the man in the study, Krogstad, is "morally diseased." After the meeting with Krogstad, Torvald comes out of the study. Nora asks him if he can give Kristine a position at the bank and Torvald is very positive, saying that this is a fortunate moment, as a position has just become available. Torvald, Kristine, and Dr. Rank leave the house, leaving Nora alone. The nanny returns with the children and Nora plays with them for a while until Krogstad creeps through the ajar door into the living room and surprises her. Krogstad tells Nora that Torvald intends to fire him from the bank and asks her to intercede with Torvald to allow him to keep his job. She refuses, and Krogstad threatens to blackmail her about the loan she took out for the trip to Italy; he knows that she obtained this loan by forging her father's signature after his death. Krogstad leaves and when Torvald returns, Nora tries to convince him not to fire Krogstad. Torvald refuses to hear her pleas, explaining that Krogstad is a liar and a hypocrite and that years before he had committed a crime: he forged other people's signatures. Torvald feels physically ill in the presence of a man "poisoning his own children with lies and dissimulation." Act Two Kristine arrives to help Nora repair a dress for a costume function that she and Torvald plan to attend the next day. Torvald returns from the bank, and Nora pleads with him to reinstate Krogstad, claiming she is worried Krogstad will publish libelous articles about Torvald and ruin his career. Torvald dismisses her fears and explains that, although Krogstad is a good worker and seems to have turned his life around, he must be fired because he is too familial around Torvald in front of other bank personnel. Torvald then retires to his study to work. Dr. Rank, the family friend, arrives. Nora asks him for a favor, but Rank responds by revealing that he has entered the terminal stage of his disease and that he has always been secretly in love with her. Nora tries to deny the first revelation and make light of it but is more disturbed by his declaration of love. She then clumsily attempts to tell him that she is not in love with him, but loves him dearly as a friend. Having been fired by Torvald, Krogstad arrives at the house. Nora convinces Dr. Rank to go into Torvald's study so he will not see Krogstad. When Krogstad confronts Nora, he declares that he no longer cares about the remaining balance of Nora's loan, but that he will instead preserve the associated bond to blackmail Torvald into not only keeping him employed but also promoting him. Nora explains that she has done her best to persuade her husband, but he refuses to change his mind. Krogstad informs Nora that he has written a letter detailing her crime (forging her father's signature of surety on the bond) and put it in Torvald's mailbox, which is locked. Nora tells Kristine of her difficult situation, gives her Krogstad's card with his address, and asks her to try to convince him to relent. Torvald enters and tries to retrieve his mail, but Nora distracts him by begging him to help her with the dance she has been rehearsing for the costume party, feigning anxiety about performing. She dances so badly and acts so childishly that Torvald agrees to spend the whole evening coaching her. When the others go to dinner, Nora stays behind for a few minutes and contemplates killing herself. Act Three Kristine tells Krogstad that she only married her husband because she had no other means to support her sick mother and young siblings and that she has returned to offer him her love again. She believes that he would not have stooped to unethical behavior if he had not been devastated by her abandonment and in dire financial straits. Krogstad changes his mind and offers to take back his letter from Torvald. However, Kristine decides that Torvald should know the truth for the sake of his and Nora's marriage. After Torvald literally drags Nora home from the party, Rank follows them. They chat for a while, with Dr. Rank conveying obliquely to Nora that this is a final goodbye, as he has determined that his death is near. Dr. Rank leaves, and Torvald retrieves his letters. As he reads them, Nora prepares to run away for good, but Torvald confronts her with Krogstad's letter. Enraged, he declares that he is now completely in Krogstad's power; he must yield to Krogstad's demands and keep quiet about the whole affair. He berates Nora, calling her a dishonest and immoral woman and telling her that she is unfit to raise their children. He says that from now on their marriage will be only a matter of appearances. A maid enters, delivering a letter to Nora. The letter is from Krogstad, yet Torvald demands to read the letter and takes it from Nora. Torvald exults that he is saved, as Krogstad has returned the incriminating bond, which Torvald immediately burns along with Krogstad's letters. He takes back his harsh words to his wife and tells her that he forgives her. Nora realizes that her husband is not the strong and gallant man she thought he was and that he truly loves himself more than he does Nora. Torvald explains that when a man has forgiven his wife, it makes him love her all the more since it reminds him that she is totally dependent on him, like a child. He preserves his peace of mind by thinking of the incident as a mere mistake that she made owing to her foolishness, one of her most endearing feminine traits. Nora tells Torvald that she is leaving him, and in a confrontational scene expresses her sense of betrayal and disillusionment. She says he has never loved her and they have become strangers to each other. She feels betrayed by his response to the scandal involving Krogstad, and she says she must get away to understand herself. She says that she has been treated like a doll to play with for her whole life, first by her father and then by him. Torvald insists that she fulfill her duty as a wife and mother, but Nora says that she has duties to herself that are just as important, and that she cannot be a good mother or wife without learning to be more than a plaything. She reveals that she had expected that he would want to sacrifice his reputation for hers and that she had planned to kill herself to prevent him from doing so. She now realizes that Torvald is not at all the kind of person she had believed him to be and that their marriage has been based on mutual fantasies and misunderstandings. Nora leaves her keys and wedding ring; Torvald breaks down and begins to cry, baffled by what has happened. After Nora leaves the room, Torvald, for one second, still has a sense of hope, and exclaims to himself "The most wonderful thing of all--?", just before the door downstairs is heard closing. Alternative ending Ibsen's German agent felt that the original ending would not play well in German theatres. In addition, copyright laws of the time would not preserve Ibsen's original work. Therefore, for it to be considered acceptable, and prevent the translator from altering his work, Ibsen was forced to write an alternative ending for the German premiere. In this ending, Nora is led to her children after having argued with Torvald. Seeing them, she collapses, and as the curtain is brought down, it is implied that she stays. Ibsen later called the ending a disgrace to the original play and referred to it as a "barbaric outrage". Virtually all productions today use the original ending, as do nearly all of the film versions of the play. Composition and publication Real-life inspiration A Doll's House was based on the life of Laura Kieler (maiden name Laura Smith Petersen), a good friend of Ibsen. Much that happened between Nora and Torvald happened to Laura and her husband, Victor. Similar to the events in the play, Laura signed an illegal loan to save her husband's life – in this case, to find a cure for his tuberculosis. She wrote to Ibsen, asking for his recommendation of her work to his publisher, thinking that the sales of her book would repay her debt. At his refusal, she forged a check for the money. At this point she was found out. In real life, when Victor discovered about Laura's secret loan, he divorced her and had her committed to an asylum. Two years later, she returned to her husband and children at his urging, and she went on to become a well-known Danish author, living to the age of 83. Ibsen wrote A Doll's House when Laura Kieler had been committed to the asylum. The fate of this friend of the family shook him deeply, perhaps also because Laura had asked him to intervene at a crucial point in the scandal, which he did not feel able or willing to do. Instead, he turned this life situation into an aesthetically shaped, successful drama. In the play, Nora leaves Torvald with head held high, though facing an uncertain future given the limitations single women faced in the society of the time. Kieler eventually rebounded from the shame of the scandal and had her own successful writing career while remaining discontented with sole recognition as "Ibsen's Nora" years afterwards. Composition Ibsen started thinking about the play around May 1878, although he did not begin its first draft until a year later, having reflected on the themes and characters in the intervening period (he visualised its protagonist, Nora, for instance, as having approached him one day wearing "a blue woolen dress"). He outlined his conception of the play as a "modern tragedy" in a note written in Rome on 19 October 1878. "A woman cannot be herself in modern society," he argues, since it is "an exclusively male society, with laws made by men and with prosecutors and judges who assess feminine conduct from a masculine standpoint!" Publication Ibsen sent a fair copy of the completed play to his publisher on 15 September 1879. It was first published in Copenhagen on 4 December 1879, in an edition of 8,000 copies that sold out within a month; a second edition of 3,000 copies followed on 4 January 1880, and a third edition of 2,500 was issued on 8 March. Production history A Doll's House received its world premiere on 21 December 1879 at the Royal Theatre in Copenhagen, with Betty Hennings as Nora, Emil Poulsen as Torvald, and Peter Jerndorff as Dr. Rank. Writing for the Norwegian newspaper Folkets Avis, the critic Erik Bøgh admired Ibsen's originality and technical mastery: "Not a single declamatory phrase, no high dramatics, no drop of blood, not even a tear." Every performance of its run was sold out. Another production opened at the Royal Theatre in Stockholm, on 8 January 1880, while productions in Christiania (with Johanne Juell as Nora and Arnoldus Reimers as Torvald) and Bergen followed shortly after. In Germany, the actress Hedwig Niemann-Raabe refused to perform the play as written, declaring, "I would never leave my children!" Since the playwright's wishes were not protected by copyright, Ibsen decided to avoid the danger of being rewritten by a lesser dramatist by committing what he called a "barbaric outrage" on his play himself and giving it an alternative ending in which Nora did not leave. A production of this version opened in Flensburg in February 1880. This version was also played in Hamburg, Dresden, Hanover, and Berlin, although, in the wake of protests and a lack of success, Niemann-Raabe eventually restored the original ending. Another production of the original version, some rehearsals of which Ibsen attended, opened on 3 March 1880 at the Residenz Theatre in Munich. In Great Britain, the only way in which the play was initially allowed to be given in London was in an adaptation by Henry Arthur Jones and Henry Herman called Breaking a Butterfly. This adaptation was produced at the Princess Theatre, 3 March 1884. Writing in 1896 in his book The Foundations of a National Drama, Jones says: "A rough translation from the German version of A Doll's House was put into my hands, and I was told that if it could be turned into a sympathetic play, a ready opening would be found for it on the London boards. I knew nothing of Ibsen, but I knew a great deal of Robertson and H. J. Byron. From these circumstances came the adaptation called Breaking a Butterfly." H. L. Mencken writes that it was A Doll's House "denaturized and dephlogisticated. … Toward the middle of the action Ibsen was thrown to the fishes, and Nora was saved from suicide, rebellion, flight and immortality by making a faithful old clerk steal her fateful promissory note from Krogstad's desk. … The curtain fell upon a happy home." Before 1899 there were two private productions of the play in London (in its original form as Ibsen wrote it) — one featured George Bernard Shaw in the role of Krogstad. The first public British production of the play in its regular form opened on 7 June 1889 at the Novelty Theatre, starring Janet Achurch as Nora and Charles Charrington as Torvald. Achurch played Nora again for a 7-day run in 1897. Soon after its London premiere, Achurch brought the play to Australia in 1889. The play was first seen in America in 1883 in Louisville, Kentucky; Helena Modjeska acted Nora. The play made its Broadway premiere at the Palmer's Theatre on 21 December 1889, starring Beatrice Cameron as Nora Helmer. It was first performed in France in 1894. Other productions in the United States include one in 1902 starring Minnie Maddern Fiske, a 1937 adaptation with acting script by Thornton Wilder and starring Ruth Gordon, and a 1971 production starring Claire Bloom. A new translation by Zinnie Harris at the Donmar Warehouse, starring Gillian Anderson, Toby Stephens, Anton Lesser, Tara FitzGerald and Christopher Eccleston opened in May 2009. The play was performed by 24/6: A Jewish Theater Company in March 2011, one of their early performances following their December 2010 lower Manhattan launch. In August 2013, Young Vic, London, Great Britain, produced a new adaptation of A Doll's House directed by Carrie Cracknell based on the English language version by Simon Stephens. In September 2014, in partnership with Brisbane Festival, La Boite located in Brisbane, Australia, hosted an adaptation of A Doll's House written by Lally Katz and directed by Stephen Mitchell Wright. In June 2015, Space Arts Centre in London staged an adaptation of A Doll's House featuring the discarded alternate ending. 'Manaveli' Toronto staged a Tamil version of A Doll's House (ஒரு பொம்மையின் வீடு)on 30 June 2018,Translated and Directed by Mr P Vikneswaran. The drama was very well received by the Tamil Community in Toronto and was staged again in few months later. The same stage play was filmed at the beginning of 2019 and screened in Toronto on 4 May 2019. The film was received with very good reviews and the artists were hailed for their performance. Now, arrangements are being made to screen the film, ஒரு பொம்மையின் வீடு, in London, at Safari Cinema Harrow, on 7 July 2019; From September 2019 to October 2019 the Lyric Hammersmith in London hosted a new adaptation of the play by Tanika Gupta who moved the setting of the play to colonial India. Though the plot largely remained unchanged, the protagonists were renamed Tom and Niru Helmer and a conversation was added regarding the British oppression of the Indian public. One significant shift was the lack of a slamming door at the end of the play. They also published a pack of teaching materials which includes extracts from the adapted play script. A production of A Doll's House by The Jamie Lloyd Company starring Jessica Chastain was initially scheduled to play at the Playhouse Theatre in London in the summer of 2020. Due to the COVID-19 pandemic, the play is now postponed to a later date. Analysis and criticism A Doll's House questions the traditional roles of men and women in 19th-century marriage. To many 19th-century Europeans, this was scandalous. The covenant of marriage was considered holy, and to portray it as Ibsen did was controversial. However, the Irish playwright George Bernard Shaw found Ibsen's willingness to examine society without prejudice exhilarating. The Swedish playwright August Strindberg criticised the play in his volume of essays and short stories Getting Married (1884). Strindberg questioned Nora's walking out and leaving her children behind with a man that she herself disapproved of so much that she would not remain with him. Strindberg also considers that Nora's involvement with an illegal financial fraud that involved Nora forging a signature, all done behind her husband's back, and then Nora's lying to her husband regarding Krogstad's blackmail, are serious crimes that should raise questions at the end of the play, when Nora is moralistically judging her husband. And Strindberg points out that Nora's complaint that she and Torvald "have never exchanged one serious word about serious things," is contradicted by the discussions that occur in act one and two. The reasons Nora leaves her husband are complex, and various details are hinted at throughout the play. In the last scene, she tells her husband she has been "greatly wronged" by his disparaging and condescending treatment of her, and his attitude towards her in their marriage – as though she were his "doll wife" — and the children in turn have become her "dolls," leading her to doubt her own qualifications to raise her children. She is troubled by her husband's behavior in regard to the scandal of the loaned money. She does not love her husband, she feels they are strangers, she feels completely confused, and suggests that her issues are shared by many women. George Bernard Shaw suggests that she left to begin "a journey in search of self-respect and apprenticeship to life," and that her revolt is "the end of a chapter of human history." Ibsen was inspired by the belief that "a woman cannot be herself in modern society," since it is "an exclusively male society, with laws made by men and with prosecutors and judges who assess feminine conduct from a masculine standpoint." Its ideas can also be seen as having a wider application: Michael Meyer argued that the play's theme is not women's rights, but rather "the need of every individual to find out the kind of person he or she really is and to strive to become that person." In a speech given to the Norwegian Association for Women's Rights in 1898, Ibsen insisted that he "must disclaim the honor of having consciously worked for the women's rights movement," since he wrote "without any conscious thought of making propaganda," his task having been "the description of humanity." However, the play is associated with feminism, as Miriam Schneir includes it in her anthology Feminism: The Essential Historical Writings, labelling it as one of the essential feminist works. Because of the departure from traditional behavior and theatrical convention involved in Nora's leaving home, her act of slamming the door as she leaves has come to represent the play itself. In Iconoclasts (1905), James Huneker noted "That slammed door reverberated across the roof of the world." Adaptations Film A Doll's House has been adapted for the cinema on many occasions, including: The 1922 lost silent film A Doll's House starring Alla Nazimova as Nora. The 1923 German silent film Nora directed by Berthold Viertel. Nora was played by Olga Chekhova, who was born Olga Knipper, and was the niece and namesake of Anton Chekhov’s wife. She was also Mikhail Chekhov's wife. The 1943 Argentine film Casa de muñecas starring Delia Garcés, which modernizes the story and uses the alternative ending. The 1954 Mexican film Casa de muñecas, directed by Alfredo B. Crevenna and starring Marga López, Ernesto Alonso and Miguel Torruco, sets the story in modern-day Mexico, adds a flashback framing device, turns Dr. Rank (renamed Dr. Eduardo Anguiano and played by Alonso, who gets second billing) into Nora's doomed suitor and savior, changes Nora's motivation for leaving her house, and adds a happy ending the following Christmas Eve. Two film versions were released in 1973: A Doll's House by Joseph Losey starring Jane Fonda, David Warner and Trevor Howard; and A Doll's House by Patrick Garland starring Claire Bloom, Anthony Hopkins, and Ralph Richardson. Dariush Mehrjui's 1992 film Sara is based on A Doll's House, with the plot transferred to Iran. Sara, played by Niki Karimi, is the Nora of Ibsen's play. In 2012, the Young Vic theatre in London released a short film titled Nora with Hattie Morahan portraying what a modern-day Nora might look like. In 2016, there were plans for a modernized adaptation starring Ben Kingsley as Doctor Rank and Michele Martin as Nora. Television The 1959 adaptation was a live version for American TV directed by George Schaefer. This version featured Julie Harris, Christopher Plummer, Hume Cronyn, Eileen Heckart and Jason Robards. In 1973, Norwegian TV produced an adaptation of A Doll's House titled Et dukkehjem directed by Arild Brinchmann and starring Lise Fjeldstad as Nora Helmer. A 1974 West German television adaptation titled was directed by Rainer Werner Fassbinder and starred Margit Carstensen in the title role. In 1992, David Thacker directed a British television adaptation with Juliet Stevenson, Trevor Eve and David Calder. Radio A Lux Radio Theatre production on 6 June 1938 starred Joan Crawford as Nora and Basil Rathbone as Torvald. A later version by the Theatre Guild on the Air on 19 January 1947 featured Rathbone again as Torvald with Dorothy McGuire as Nora. In 2012, BBC Radio 3 broadcast an adaptation by Tanika Gupta transposing the setting to India in 1879, where Nora (renamed 'Niru') is an Indian woman married to Torvald (renamed 'Tom'), an English man working for the British Colonial Administration in Calcutta. This production starred Indira Varma as Niru and Toby Stephens as Tom. Re-staging In 1989, film and stage director Ingmar Bergman staged and published a shortened reworking of the play, now entitled Nora, which entirely omitted the characters of the servants and the children, focusing more on the power struggle between Nora and Torvald. It was widely viewed as downplaying the feminist themes of Ibsen's original. The first staging of it in New York was reviewed by the Times as heightening the play's melodramatic aspects. The Los Angeles Times stated that "Nora shores up A Doll's House in some areas but weakens it in others." Lucas Hnath wrote A Doll's House, Part 2 as a follow-up about Nora 15 years later. In 2017, performance artist Cherdonna Shinatra wrote and starred in a reworking of the play titled "Cherdonna's Doll House" under the direction of Ali Mohamed el-Gasseir. The production was staged at 12th Avenue Arts through Washington Ensemble Theatre. Brendan Kiley of The Seattle Times described it as a "triple-decker satire" in which "Cherdonna’s version of Ibsen’s play about femininity turns into a kind of memoir about Kuehner’s neither-here-nor-there career identity." The Citizens' Theatre in Glasgow have performed Nora: A Doll's House by Stef Smith, a radical re-working of the play, with three actors playing Nora, simultaneously taking place in 1918, 1968 and 2018. The production later transferred to the Young Vic in London. Dottok-e-Log (Doll's House), adapted and directed by Kashif Hussain, was performed in the Balochi language at the National Academy of Performing Arts on 30 and 31 March 2019. Novels In 2019, memoirist, journalist and professor Wendy Swallow published Searching for Nora: After the Doll's House. Swallow's historical novel tells the story of Nora Helmer's life from the moment in December 1879 that Nora walks out on her husband and young children at the close of A Doll's House. Swallow draws from her research into Ibsen's play and iconic protagonist, the realities of the time, and the 19th-century Norwegian emigration to America, following Nora as she first struggles to survive in Kristiania (today's Oslo) and then travels by boat, train and wagon to a new home in the western prairie of Minnesota. Dance Stina Quagebeur's ballet Nora for the English National Ballet premiered in 2019, with Crystal Costa as Nora and Jeffrey Cirio as Torvald, set to Philip Glass's Tirol Concerto for Piano and Orchestra.

AIM-7 Sparrow

The AIM-7 Sparrow (Air Intercept Missile) is an American, medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, and United States Marine Corps, as well as other various air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM. The early Sparrow was intended primarily for use against larger targets, especially bombers and had numerous operational limitations in other uses. Against smaller targets, the need to receive a strong reflected radar signal made achieving lock-on at the missile's effective range difficult. As the launching aircraft's own radar needed to be pointed at the target throughout the engagement, this meant that in fighter-vs-fighter combat, the enemy fighter would often approach within the range of shorter-range infrared homing missiles while the launching aircraft had to continue flying towards its target. Additionally, early models were only effective against targets at roughly the same or higher altitudes, below which reflections from the ground became a problem. A number of upgraded Sparrow designs were developed to address these issues. In the early 1970s, the RAF developed a version with an inverse monopulse seeker and improved motor known as Skyflash, while the Italian Air Force introduced the similar Aspide. Both had the ability to be fired at targets below the launching fighter ("look-down, shoot down"), were more resistant to countermeasures, and were much more accurate in the terminal phase. This basic concept was then made part of the US Sparrows in the M model (for monopulse) and some of these were later updated as the P model, the last to be produced in the US. Aspides sold to China resulted in the locally produced PL10. The Japan Self-Defense Forces also employ the Sparrow missile, though it is being phased out and replaced by the Mitsubishi AAM-4. The Sparrow was also used as the basis for a surface-to-air missile, the RIM-7 Sea Sparrow, used by a number of navies for air defense. Fired at low altitude and flying directly at its target, although, the range of the missile in this role is greatly reduced due to the lower atmosphere. With the retirement of the Sparrow in the air-to-air role, a new version of the Sea Sparrow was produced to address this concern, producing the larger and more capable RIM-162 ESSM. Development Sparrow I Sparrow emerged from a late-1940s United States Navy program to develop a guided rocket weapon for air-to-air use. In 1947 the Navy contracted Sperry to build a beam riding version of a standard HVAR, the standard unguided aerial rocket, under Project Hotshot. The weapon was initially dubbed KAS-1, then AAM-2, and, from 1948 on, AAM-N-2. The airframe was developed by Douglas Aircraft Company. The diameter of the HVAR proved to be inadequate for the electronics, leading Douglas to expand the missile's airframe to diameter. The prototype weapon began unpowered flight-tests in 1947, and made its first aerial interception in 1952. After a protracted development cycle the initial AAM-N-2 Sparrow entered limited operational service in 1954 with specially modified Douglas F3D Skyknight all-weather carrier night fighters. In 1956, they were joined by the McDonnell F3H-2M Demon and Vought F7U Cutlass fighter aircraft. Compared to the modern versions, the Sparrow I was more streamlined and featured a bullet-shaped airframe with a long pointed nose. Sparrow I was a limited and rather primitive weapon. The limitations of beam-riding guidance (which was slaved to an optical sight on single-seater fighters and radar with night fighters) restricted the missile to attacks against targets flying a straight course and made it essentially useless against a maneuvering target. Only about 2,000 rounds were produced to this standard. Sparrow II As early as 1950 Douglas examined equipping the Sparrow with an active radar seeker, initially known as XAAM-N-2a Sparrow II, the original retroactively becoming Sparrow I. In 1952 it was given the new code AAM-N-3. The active radar made the Sparrow II a "fire and forget" weapon, allowing several to be fired at separate targets at the same time. By 1955 Douglas proposed going ahead with development, intending it to be the primary weapon for the F5D Skylancer interceptor. It was later selected, with some controversy, to be the primary weapon for the Canadian Avro Arrow supersonic interceptor, along with the new Astra fire-control system. For Canadian use and as a second source for US missiles, Canadair was selected to build the missiles in Quebec. The small size of the missile forebody and the K-band AN/APQ-64-radar limited performance, and it was never able to work in testing. After considerable development and test firings in the U.S. and Canada, Douglas abandoned development in 1956. Canadair continued development until the Arrow was cancelled in 1959. Sparrow X A subvariant of the Sparrow I armed with the same nuclear warhead as the MB-1 Genie was proposed in 1958 but was cancelled shortly thereafter. Sparrow III Concurrently with the development of the Sparrow I, in 1951, Raytheon began work on the semi-active radar homing version of Sparrow family of missiles, the AAM-N-6 Sparrow III. The first of these weapons entered United States Navy service in 1958. The AAM-N-6a was similar to the -6, but used a new Thiokol liquid-fuel rocket engine for improved performance. It also included changes to the guidance electronics to make it effective at higher closing speeds. The -6a was also selected to arm the Air Force's F-110A Spectre (F-4 Phantom) fighters in 1962, known to them as the AIM-101. It entered production in 1959, with 7500 being built. Another upgrade reverted to a Rocketdyne solid-fuel motor for the AAM-N-6b, which started production in 1963. The new motor significantly increased the maximum range to for head-on attacks. During this year the Air Force and Navy agreed on standardized naming conventions for their missiles. The Sparrows became the AIM-7 series. The original Sparrow I and aborted Sparrow II became the AIM-7A and AIM-7B, despite both being out of service. The -6, -6a, and -6b became the AIM-7C, AIM-7D, and AIM-7E respectively. 25,000 AIM-7Es were produced and saw extensive use during the Vietnam War, where its performance was considered disappointing. The mixed results were a combination of reliability problems (exacerbated by the tropical climate), limited pilot training in fighter-to-fighter combat, and restrictive rules of engagement that generally prohibited BVR (beyond visual range) engagements. The Pk (kill probability) of the AIM-7E was less than 10%; US fighter pilots shot down 59 aircraft out of the 612 Sparrows fired. Of the 612 AIM-7D/E/E-2 missiles fired, 97 (or 15.8%) hit their targets, resulting in 56 (or 9.2%) kills. Two kills were obtained beyond visual range. In 1969 an improved version, the E-2, was introduced with clipped wings and various changes to the fuzing. Considered a "dogfight Sparrow", the AIM-7E-2 was intended to be used at shorter ranges where the missile was still travelling at high speeds, and in the head-on aspect, making it much more useful in the visual limitations imposed on the engagements. Even so, its kill rate was only 13% in combat, leading to a practice of ripple-firing all four at once in hopes of increasing kill probability. Its worst tendency was that of detonating prematurely, approximately a thousand feet in front of the launching aircraft, but it also had many motor failures, erratic flights, and fuzing problems. An E-3 version included additional changes to the fuzing, and an E-4 featured a modified seeker for use with the F-14 Tomcat. Vietnam War (1965–1973) records Improved versions of the AIM-7 were developed in the 1970s in an attempt to address the weapon's limitations. The AIM-7F, which entered service in 1976, had a dual-stage rocket motor for longer range, solid-state electronics for greatly improved reliability, and a larger warhead. Even this version had room for improvement, leading British Aerospace and the Italian firm Alenia to develop advanced versions of Sparrow with better performance and improved electronics as the BAe Skyflash and Alenia Aspide, respectively. The most common version of the Sparrow today, the AIM-7M, entered service in 1982 and featured a new inverse monopulse seeker (matching the capabilities of Skyflash), active radar proximity fuse, digital controls, improved ECM resistance, and better low-altitude performance. It was used to good advantage in the 1991 Gulf War, where it scored many USAF air-to-air kills. Of 44 missiles fired, 30 (68.2%) hit their intended targets resulting in 24/26 (54.5%/59.1%) kills. 19 kills were obtained beyond visual range. The AIM-7P is similar in most ways to the M versions, and was primarily an upgrade program for existing M-series missiles. The main changes were to the software, improving low-level performance. A follow-on Block II upgrade added a new rear receiver allowing the missile to receive mid-course correction from the launching aircraft. Plans initially called for all M versions to be upgraded, but currently P's are being issued as required to replace M's lost or removed from the inventory. The final version of the missile was to have been the AIM-7R, which added an infrared homing seeker to an otherwise unchanged AIM-7P Block II. A general wind-down of the budget led to it being cancelled in 1997. Sparrow is now being phased out with the availability of the active-radar AIM-120 AMRAAM, but is likely to remain in service for several years. Foreign versions Canada As part of the Avro Canada CF-105 Arrow program, Canadair (now Bombardier) partnered with Douglas Aircraft Company in the development of the Sparrow II (AAM-N-3/AIM-7B). After Douglas dropped out of this program, Canadair continued on with it until the termination of the Arrow project. The AAM-N-3 Sparrow II was unique in that it had a fully active radar guidance system. This combined both a radar transmitter and receiver in the missile, making it unnecessary for the pilot to keep the aircraft aimed at the target after firing the missile, unlike Semi-active radar homing (SARH) missiles which require continuous radar-assisted guidance throughout flight. This allowed the aircraft that fired the AAM-N-3 to turn away, prosecute other targets, and/or escape from potential retaliatory missiles fired by the enemy aircraft during the time it takes for the Sparrow to reach its target. Despite the significant advantages of this design over SARH guidance, all subsequent models of the Sparrow use semi-active radar homing. To accommodate the active radar guidance system, the AAM-N-3 Sparrow II had a much greater volume than its predecessor. Its size would subsequently set the precedent for all future Sparrow variants. In 1959, Canadair had completed five missiles based on airframes from Douglas, and built two models from scratch, when the program was cancelled with the cancellation of the Arrow. Italy The Italian company Finmeccanica (now Leonardo S.p.A.), Alenia Difesa licensed the AIM-7E Sparrow technology from the US, and produced its own version. Later in the 1980s, Alenia started to produce an improved version of the AIM-7 called the Aspide, compared to the AIM-7E, it received a newer and improved monopulse guiding system that allowed for a better hit ratio and easier targeting of enemies at low altitude confused in the ground clutter. It also received a new and more powerful engine and new control surfaces, these control surfaces were all independent one of the others, this gave the missile a much better maneuverability compared to the AIM-7E and the English Skyflash that still used dependent control surfaces. People's Republic of China The LY-60/FD-60/PL-10 is a family of PRC missiles developed by the Shanghai Academy of Science and Technology, largely based on the Italian Aspide missile – a version of the Sparrow. There are four versions of the basic design, three of which are surface-to-air and one air-to-air. Soviet Union The Soviet Union acquired an AIM-7 in 1968 and a Vympel team started copying it as the K-25. The missile did not enter production as the R-23 was thought to have better versatility, range, signal processing logic, and immunity from interference. K-25 work ended in 1971, but analysis of the Sparrow was later used to inform the design of the Vympel R-27, particularly the servomechanisms and movable wings. UK British Aerospace (BAe) licensed the AIM-7E2 technology in the 1970s, producing the Skyflash missile. Skyflash used a Marconi XJ521 monopulse seeker together with improvements to the electronics. It was powered by the Aerojet Mk52 mod 2 rocket engine (later by the Rocketdyne Mk38 mod 4). Skyflash entered service with the Royal Air Force (RAF) on their Phantom FG.1/FGR.2 in 1978, and later on the Tornado F3. Skyflash was also exported to Sweden for use on their Viggen fighters. An upgraded version with active radar seeker, called Active Sky Flash was proposed by BAe and Thomson-CSF, but did not receive funding because the RAF opted for other missiles. Design The Sparrow has four major sections: guidance section, warhead, control, and rocket motor (currently the Hercules MK-58 solid-propellant rocket motor). It has a cylindrical body with four wings at mid-body and four tail fins. Although the external dimensions of the Sparrow remained relatively unchanged from model to model, the internal components of newer missiles represent major improvements, with vastly increased capabilities. The warhead is of the continuous-rod type. As with other semi-active radar guided missiles, the missile does not generate radar signals, but instead homes in on reflected continuous-wave signals from the launch platform's radar. The receiver also senses the guidance radar to enable comparisons that enhance the missile's resistance to passive jamming. Principle of guidance The launching aircraft will illuminate the target with its radar. In radars of the 1950s these were single target tracking devices using a nutating horn as part of the antenna. This caused the beam to be swept in a small cone. Signal processing would be applied to determine the direction of maximum illumination and so develop a signal to steer the antenna toward the target. The missile detects the reflected signal from the target with a high gain antenna in a similar fashion and steers the entire missile toward closure with the target. The missile guidance also samples a portion of the illuminating signal via rearward pointing waveguides. The comparison of these two signals enabled logic circuits to determine the true target reflection signal, even if the target were to eject radar-reflecting chaff.

AIM-120 AMRAAM

The AIM-120 Advanced Medium-Range Air-to-Air Missile, or AMRAAM (pronounced ), is an American beyond-visual-range air-to-air missile (BVRAAM) capable of all-weather day-and-night operations. Designed with a diameter, and employing active transmit-receive radar guidance instead of semi-active receive-only radar guidance, it has the advantage of being a fire-and-forget weapon when compared to the previous generation Sparrow missiles. When an AMRAAM missile is launched, NATO pilots use the brevity code Fox Three. The AMRAAM is the world's most popular beyond-visual-range missile; more than 14,000 have been produced for the United States Air Force, the United States Navy, and 33 international customers. The AMRAAM has been used in several engagements and is credited with sixteen air-to-air kills in conflicts over Iraq, Bosnia, Kosovo, Kashmir, and Syria. Now over 30 years old in design, the AMRAAM is due to be replaced by the new AIM-260 JATM, which will offer better long-range performance and ability to defeat electronic warfare jamming. Origins AIM-7 Sparrow MRM The AIM-7 Sparrow medium range missile (MRM) was purchased by the US Navy from original developer Hughes Aircraft in the 1950s as its first operational air-to-air missile with "beyond visual range" (BVR) capability. With an effective range of about , it was introduced as a radar beam-riding missile and then it was improved to a semi-active radar guided missile which would home in on reflections from a target illuminated by the radar of the launching aircraft. It was effective at visual to beyond visual range. The early beam riding versions of the Sparrow missiles were integrated onto the McDonnell F3H Demon and Vought F7U Cutlass, but the definitive AIM-7 Sparrow was the primary weapon for the all-weather McDonnell Douglas F-4 Phantom II fighter/interceptor, which lacked an internal gun in its U.S. Navy, U.S. Marine Corps, and early U.S. Air Force versions. The F-4 carried up to four AIM-7s in built-in recesses under its belly. Although designed for use against non-maneuvering targets such as bombers, because of poor performance against fighters over North Vietnam, these missiles were progressively improved until they proved highly effective in dogfights. Together with the short-range, infrared-guided AIM-9 Sidewinder, they replaced the AIM-4 Falcon IR and radar guided series for use in air combat by the USAF as well. A disadvantage to semi-active homing was that only one target could be illuminated by the launching fighter plane at a time. Also, the launching aircraft had to remain pointed in the direction of the target (within the azimuth and elevation of its own radar set) which could be difficult or dangerous in air-to-air combat. An active-radar variant called the Sparrow II was developed to address these drawbacks, but the U.S. Navy pulled out of the project in 1956. The Royal Canadian Air Force, which took over development in the hopes of using the missile to arm their prospective Avro Canada CF-105 Arrow interceptor, soon followed in 1958. The electronics of the time simply could not be miniaturized enough to make Sparrow II a viable working weapon. It would take decades, and a new generation of digital electronics, to produce an effective active-radar air-to-air missile as compact as the Sparrow. AIM-54 Phoenix LRM The US Navy later developed the AIM-54 Phoenix long-range missile (LRM) for the fleet air defense mission. It was a large , Mach 5 missile designed to counter cruise missiles and the bombers that launched them. Originally intended for the straight-wing Douglas F6D Missileer and then the navalized General Dynamics–Grumman F-111B, it finally saw service with the Grumman F-14 Tomcat, the only fighter capable of carrying such a heavy missile. Phoenix was the first US fire-and-forget, multiple-launch, radar-guided missile: one which used its own active guidance system to guide itself without help from the launch aircraft when it closed on its target. This, in theory, gave a Tomcat with a six-Phoenix load the unprecedented capability of tracking and destroying up to six targets beyond visual range, as far as away—the only US fighter with such capability. A full load of six Phoenix missiles and its dedicated launcher exceeded a typical Vietnam-era bomb load. Its service in the US Navy was primarily as a deterrent, as its use was hampered by restrictive rules of engagement in conflicts such as 1991 Gulf War, Southern Watch (enforcing no-fly zones), and Iraq War. The US Navy retired the Phoenix in 2004 in light of availability of the AIM-120 AMRAAM on the McDonnell Douglas F/A-18 Hornet and the pending retirement of the F-14 Tomcat from active service in late 2006. ACEVAL/AIMVAL The Department of Defense conducted an extensive evaluation of air combat tactics and missile technology from 1974 to 1978 at Nellis AFB using the F-14 Tomcat and F-15 Eagle equipped with Sparrow and Sidewinder missiles as the blue force and aggressor F-5E aircraft equipped with AIM-9L all-aspect Sidewinders as the red force. This joint test and evaluation (JT&E) was designated Air Combat Evaluation/Air Intercept Missile Evaluation (ACEVAL/AIMVAL). A principal finding was that the necessity to produce illumination for the Sparrow until impact resulted in the red force's being able to launch their all-aspect Sidewinders before impact, resulting in mutual kills. What was needed was Phoenix-type multiple-launch and terminal active capability in a Sparrow-size airframe. This led to a memorandum of agreement (MOA) with European allies (principally the UK and Germany for development) for the US to develop an advanced, medium-range, air-to-air missile with the USAF as lead service. The MOA also assigned responsibility for development of an advanced, short-range, air-to-air missile to the European team; this would become the British ASRAAM. Requirements By the 1990s, the reliability of the Sparrow had improved so much from the dismal days of Vietnam that it accounted for the largest number of aerial targets destroyed in Desert Storm part of Gulf War But while the USAF had passed on the Phoenix and their own similar AIM-47 Falcon/Lockheed YF-12 to optimize dogfight performance, they still needed a multiple-launch fire-and-forget capability for the F-15 and F-16. AMRAAM would need to be fitted on fighters as small as the F-16, and fit in the same spaces that were designed to fit the Sparrow on the F-4 Phantom. The European partners needed AMRAAM to be integrated on aircraft as small as the BAe Sea Harrier. The US Navy needed AMRAAM to be carried on the F/A-18 Hornet and wanted capability for two to be carried on a launcher that normally carried one Sparrow to allow for more air-to-ground weapons. The AMRAAM became one of the primary air-to-air weapons of the new Lockheed Martin F-22 Raptor fighter, which needed to place all of its weapons into internal weapons bays in order to help achieve an extremely low radar cross-section. Development AMRAAM was developed as the result of an agreement (the Family of Weapons MOA, no longer in effect by 1990), among the United States and several other NATO nations to develop air-to-air missiles and to share production technology. Under this agreement the U.S. was to develop the next generation medium range missile (AMRAAM) and Europe would develop the next generation short range missile (ASRAAM). Although Europe initially adopted the AMRAAM, an effort to develop the MDBA Meteor, a competitor to AMRAAM, was begun in UK. Eventually the ASRAAM was developed solely by the British, but using another source for its infrared seeker. After protracted development, the deployment of AMRAAM (AIM-120A) began in September 1991 in US Air Force McDonnell Douglas F-15 Eagle fighter squadrons. The US Navy soon followed (in 1993) in its McDonnell Douglas F/A-18 Hornet squadrons. The Russian Air Force counterpart of AMRAAM is the somewhat similar R-77 (NATO codename AA-12 Adder), sometimes referred to in the West as the "AMRAAMski" Likewise, France began its own air-to-air missile development with the MICA concept that used a common airframe for separate radar-guided and infrared-guided versions. Operational history United States of America The AMRAAM was used for the first time on December 27, 1992, when a USAF General Dynamics F-16D Fighting Falcon shot down an Iraqi MiG-25 that violated the southern no-fly-zone. This missile had been returned from the flight line as defective a day earlier. The AMRAAM gained a second victory in January 1993 when an Iraqi MiG-23 was shot down by a USAF F-16C. On 28 February 1994, a Republika Srpska Air Force J-21 Jastreb aircraft was shot down by a USAF F-16C that was patrolling the UN-imposed no-fly zone over Bosnia. In that engagement, at least three other Serbian aircraft were shot down by USAF F-16Cs using AIM-9 missiles (Banja Luka incident ). At that point, three launches in combat had resulted in three kills, resulting in the AMRAAM's being informally named "slammer" in the second half of the 1990s. In 1994, two USAF F-15 fighters patrolling Iraq's Northern No-Fly Zone mistook a pair of US Army Black Hawk helicopters for Iraqi helicopters, and shot them down. One was downed with an AIM-120, and one with an AIM-9 Sidewinder. In 1998 and 1999 AMRAAMs were again fired by USAF F-15 fighters at Iraqi aircraft violating the No-Fly-Zone, but this time they failed to hit their targets. During spring 1999, AMRAAMs saw their main combat action during Operation Allied Force, the Kosovo bombing campaign. Six Serbian MiG-29 were shot down by NATO (four USAF F-15Cs, one USAF F-16C, and one Dutch F-16A MLU), all of them using AIM-120 missiles (the supposed kill by the F-16C may have actually been friendly fire, a man-portable SA-7 fired by Serbian infantry). On 18 June 2017, a US Boeing F/A-18E Super Hornet engaged and shot down a Sukhoi Su-22 of the Syrian Air Force over northern Syria, using an AIM-120. An AIM-9X Sidewinder had failed to bring down the Syrian jet. Some sources have claimed the AIM-9X was decoyed by flares, although the F/A-18E pilot, Lt. Cmdr. Michael Tremel stated it was unclear why the AIM-9X failed, mentioning no use of flares by the Su-22, saying "I [lost] the smoke trail, and I have no idea kind of what happened to the missile at that point". On 7 August 2018, a Spanish Air Force Eurofighter Typhoon accidentally launched a missile in Estonia. There were no human casualties, but a ten-day search operation for missile remains was unsuccessful. Turkey On 24 November 2015 a Turkish Air Force F-16 shot down a Russian Su-24M strike aircraft with an AIM-120 missile over northern Syria after it allegedly crossed into Turkish airspace. On 1 March 2020, Turkish Air Force F-16s downed two Su-24s belonging to the Syrian Air Force using two AIM-120C-7s. On 3 March 2020, a Syrian Air Force L-39 was shot down by Turkish Air Force F-16s flying inside the Turkish airspace with AIM-120C-7 at a distance of about . As of 2020, this has been the longest AIM-120 kill. Pakistan On 27 February 2019, India stated that Pakistan Air Force (PAF) used AMRAAMs during Operation Swift Retort. Indian officials displayed fragments of an alleged AIM-120C-5 missile as a proof of its usage during the engagement. The only confirmed loss of the engagement was an Indian Air Force MiG-21. IAF officials also told the media that an IAF Sukhoi Su-30MKI had dodged and jammed 3-4 AMRAAMs during the dogfight. Saudi Arabia During the Yemeni War, Saudi Arabia extensively used F-15 and Typhooon aircraft together with Patriot batteries to intercept and down Yemeni drones and missiles. In November 2021, a possible Foreign Military Sales contract was notified to the US Congress regarding the provision to Saudi Arabia for a mix of 280 AIM-120C-7 and C-8 missiles and related support equipment and service that would be used on Saudi F-15 and Typhoon aircraft. The deal was required to replenish Saudi missiles stock, running low due to intensive use of AMRAAMs and Patriots to shot down Yemeni missiles and drones. Operational features summary AMRAAM has an all-weather, beyond-visual-range (BVR) capability. It improves the aerial combat capabilities of US and allied aircraft to meet the threat of enemy air-to-air weapons as they existed in 1991. AMRAAM serves as a follow-on to the AIM-7 Sparrow missile series. The new missile is faster, smaller, and lighter, and has improved capabilities against low-altitude targets. It also incorporates a datalink to guide the missile to a point where its active radar turns on and makes terminal intercept of the target. An inertial reference unit and micro-computer system makes the missile less dependent upon the fire-control system of the aircraft. Once the missile closes in on the target, its active radar guides it to intercept. This feature, known as "fire-and-forget", frees the aircrew from the need to further provide guidance, enabling the aircrew to aim and fire several missiles simultaneously at multiple targets and break a radar lock after the missile seeker goes active and guide themselves to the targets. The missile also features the ability to "Home on Jamming," giving it the ability to switch over from active radar homing to passive homing – homing on jamming signals from the target aircraft. Software on board the missile allows it to detect if it is being jammed, and guide on its target using the proper guidance system. Guidance system overview Interception course stage AMRAAM uses two-stage guidance when fired at long range. The aircraft passes data to the missile just before launch, giving it information about the location of the target aircraft from the launch point and its direction and speed. The missile uses this information to fly on an interception course to the target using its built-in inertial navigation system (INS). This information is generally obtained using the launching aircraft's radar, although it could come from an infrared search and track system, from a data link from another fighter aircraft, or from an AWACS aircraft. After launch, if the firing aircraft or surrogate continues to track the target, periodic updates—such as changes in the target's direction and speed—are sent from the launch aircraft to the missile, allowing the missile to adjust its course, via actuation of the rear fins, so that it is able to close to a self-homing distance where it will be close enough to "catch" the target aircraft in the basket (the missile's radar field of view in which it will be able to lock onto the target aircraft, unassisted by the launch aircraft). Not all armed services using the AMRAAM have elected to purchase the mid-course update option, which limits AMRAAM's effectiveness in some scenarios. The RAF initially opted not to use mid-course update for its Tornado F3 force, only to discover that without it, testing proved the AMRAAM was less effective in beyond visual range (BVR) engagements than the older semi-active radar homing BAE Skyflash (a development of Sparrow) weapon—the AIM-120's own radar is necessarily of limited range and power compared to that of the launch aircraft. Terminal stage and impact Once the missile closes to self-homing distance, it turns on its active radar seeker and searches for the target aircraft. If the target is in or near the expected location, the missile will find it and guide itself to the target from this point. If the missile is fired at short range, within visual range (WVR) or the near BVR, it can use its active seeker just after launch to guide it to intercept. Boresight Visual mode Apart from the radar-slaved mode, there is a free guidance mode, called "Visual". This mode is radar guidance-free—the missile just fires and locks onto the first thing it sees. This mode can be used for defensive shots, i.e. when the enemy has numerical superiority. Kill probability and tactics General considerations The kill probability (Pk) is determined by several factors, including aspect (head-on interception, side-on or tail-chase), altitude, the speed of the missile and the target, and how hard the target can turn. Typically, if the missile has sufficient energy during the terminal phase, which comes from being launched at close range to the target from an aircraft with an altitude and speed advantage, it will have a good chance of success. This chance drops as the missile is fired at longer ranges as it runs out of overtake speed at long ranges, and if the target can force the missile to turn it might bleed off enough speed that it can no longer chase the target. Operationally, the missile, which was designed for beyond visual range combat, has a Pk of 0.59. The targets included six MiG-29s, a MiG-25, a MiG-23, two Su-22s, a Galeb and a US Army Blackhawk that was targeted by mistake. Variants and upgrades Air-to-air missile versions There are currently four main variants of AMRAAM, all in service with the United States Air Force, United States Navy, and the United States Marine Corps. The AIM-120A is no longer in production and shares the enlarged wings and fins with the successor AIM-120B. The AIM-120C has smaller "clipped" aerosurfaces to enable internal carriage on the USAF F-22 Raptor. AIM-120B deliveries began in 1994. The AIM-120C deliveries began in 1996. The C-variant has been steadily upgraded since it was introduced. The AIM-120C-6 contained an improved fuze (Target Detection Device) compared to its predecessor. The AIM-120C-7 development began in 1998 and included improvements in homing and greater range (actual amount of improvement unspecified). It was successfully tested in 2003 and is currently being produced for both domestic and foreign customers. It helped the U.S. Navy replace the F-14 Tomcats with F/A-18E/F Super Hornets – the loss of the F-14's long-range AIM-54 Phoenix missiles (already retired) is offset with a longer-range AMRAAM-D. The lighter weight of the enhanced AMRAAM enables an F/A-18E/F pilot greater bring-back weight upon carrier landings. The AIM-120D is an upgraded version of the AMRAAM with improvements in almost all areas, including 50% greater range (than the already-extended range AIM-120C-7) and better guidance over its entire flight envelope yielding an improved kill probability (Pk). Raytheon began testing the D model on August 5, 2008, the company reported that an AIM-120D launched from an F/A-18F Super Hornet passed within lethal distance of a QF-4 target drone at the White Sands Missile Range. The range of the AIM-120D is classified, but is thought to extend to about . The AIM-120D (P3I Phase 4, formerly known as AIM-120C-8) is a development of the AIM-120C with a two-way data link, more accurate navigation using a GPS-enhanced IMU, an expanded no-escape envelope, and improved HOBS (high off-boresight) capability. The AIM-120D max speed is Mach 4 and AIM-120D is a joint USAF/USN project, and is currently in the testing phase. The USN was scheduled to field it from 2014, and AIM-120D will be carried by all Pacific carrier groups by 2020, although the 2013 sequestration cuts could push back this later date to 2022. The Royal Australian Air Force requested 450 AIM-120D missiles, which would make it the first foreign operator of the missile. The procurement, approved by the US Government in April 2016, will cost $1.1 billion and will be integrated for use on the F/A-18F Super Hornet, EA-18G Growler and the F-35 Lightning II aircraft. There were also plans for Raytheon to develop a ramjet-powered derivative of the AMRAAM, the Future Medium Range Air-Air Missile (FMRAAM). The FMRAAM was not produced since the target market, the British Ministry of Defence, chose the Meteor missile over the FMRAAM for a BVR missile for the Eurofighter Typhoon aircraft. Raytheon is also working with the Missile Defense Agency to develop the Network Centric Airborne Defense Element (NCADE), an anti-ballistic missile derived from the AIM-120. This weapon will be equipped with a ramjet engine and an infrared homing seeker derived from the Sidewinder missile. In place of a proximity-fuzed warhead, the NCADE will use a kinetic energy hit-to-kill vehicle based on the one used in the Navy's RIM-161 Standard Missile 3. The -120A and -120B models are currently nearing the end of their service life while the -120D variant has just entered full production. AMRAAM was due to be replaced by the USAF, the U.S. Navy, and the U.S. Marine Corps after 2020 by the Joint Dual Role Air Dominance Missile (Next Generation Missile), but it was terminated in the 2013 budget plan. Exploratory work was started in 2017 on a replacement called Long-Range Engagement Weapon. In 2017, work on the AIM-260 Joint Advanced Tactical Missile (JATM) began to create a longer-ranged replacement for the AMRAAM to contend with foreign weapons like the Chinese PL-15. Flight tests are planned to begin in 2021 and initial operational capability is slated for 2022, facilitating the end of AMRAAM production by 2026. Ground-launched systems Raytheon successfully tested launching AMRAAM missiles from a five-missile carrier on a M1097 HMMWV. This system will be known as the SLAMRAAM (Surface Launched AMRAAM). They receive their initial guidance information from a radar not mounted on the vehicle. Since the missile is launched without the benefit of an aircraft's speed or high altitude, its range is considerably shorter. Raytheon is currently marketing an SL-AMRAAM EX, purported to be an extended range AMRAAM and bearing a resemblance to the RIM-162 ESSM. The Norwegian Advanced Surface-to-Air Missile System (NASAMS), developed by Kongsberg Defence & Aerospace, consists of a number of towed launch batteries (containing six AMRAAMs each) along with separate radar trucks and control station vehicles. A more recent version of the program is the High Mobility Launcher, made in cooperation with Raytheon (Kongsberg Defence & Aerospace was already a subcontractor on the SLAMRAAM system), where the launch-vehicle is a Humvee (M1152A1 HMMWV), containing four AMRAAMs each. While still under evaluation for replacement of current US Army assets, the SL-AMRAAM has been deployed in several nations' military forces. The United Arab Emirates (UAE) has requested the purchasing of SL-AMRAAM as part of a larger $7 billion foreign military sales package. The sale would include 288 AMRAAM C-7 missiles. The US Army has test fired the SL-AMRAAM from a HIMARS artillery rocket launcher as a common launcher, as part of a move to switch to a larger and more survivable launch platform. On January 6, 2011, Secretary of Defense Robert Gates announced that the U.S. Army has decided to terminate acquisition of the SLAMRAAM as part of a budget-cutting effort. The National Guard Association of the United States has sent a letter asking for the U.S. Senate to stop the Army's plan to drop the SLAMRAAM program because without it there would be no path to modernize the Guard's AN/TWQ-1 Avenger Battalions. On 22 February 2015, Raytheon announced an Extended Range upgrade to NASAMS-launched AMRAAM, calling it AMRAAM-ER. This combines the AMRAAM seeker with the ESSM rocket motor. Foreign sales Canadair, now Bombardier, had largely helped with the development of the AIM-7 Sparrow and Sparrow II, and assisted to a lesser extent in the AIM-120 development. Canada had placed an order for 256 AIM-120's, but cancelled half of them after engine ignition problems due to cold weather conditions. The AIM-9X & AIM-7 were ordered as replacements. In early 1995 South Korea ordered 88 AIM-120A missiles for its KF-16 fleet. In 1997 South Korea ordered 737 additional AIM-120B missiles. In 2006 Poland received AIM-120C-5 missiles to arm its new F-16C/D Block 52+ fighters. In 2017 Poland ordered AIM-120C-7 missiles. In early 2006, the Pakistan Air Force (PAF) ordered 500 AIM-120C-5 AMRAAM missiles as part of a $650 million F-16 ammunition deal to equip its F-16C/D Block 50/52+ and F-16A/B Block 15 MLU fighters. The PAF got the first three F-16C/D Block 50/52+ aircraft on July 3, 2010 and first batch of AMRAAMs on July 26, 2010. In 2007, the United States government agreed to sell 218 AIM-120C-7 missiles to Taiwan as part of a large arms sales package that also included 235 AGM-65G-2 Maverick missiles. Total value of the package, including launchers, maintenance, spare parts, support and training rounds, was estimated at around US$421 million. This supplemented an earlier Taiwanese purchase of 120 AIM-120C-5 missiles a few years ago. In 2008 there were announcements of new or additional sales to Singapore, Finland, Morocco and South Korea; in December 2010 the Swiss government requested 150 AIM-120C-7 missiles. Sales to Finland have stalled, because the manufacturer has not been able to fix a mysterious bug that causes the rocket motors of the missile to fail in cold tests. On May 5, 2015, the State Department has made a determination approving a possible Foreign Military Sale to Royal Malaysian Air Force for AIM-120C7 AMRAAM missiles and associated equipment, parts and logistical support for an estimated cost of $21 million. In March 2016, the US government approved the sales of AIM-120C-7 missiles to the Indonesian Air Force to equip their fleet of F-16 C/D Block 52ID. The AIM-120C-7 is also equipped for the upgraded F-16 A/B Block 15 OCU through Falcon Star-eMLU upgrade project. In March 2019, the US Department of State and Defense Security Cooperation Agency formally signed off on a US$240.5 million foreign military sale to support Australia’s introduction of the NASAMS and LAND 19 Phase 7B program. As part of the deal, the Australian government requested up to 108 Raytheon AIM-120C-7 AMRAAM, six AIM-120C-7 AMRAAM Air Vehicles Instrumented; and six spare AIM-120C-7 AMRAAM guidance sections. In December 2019, the United States Congress approved the sale of AIM-120C-7/C-8 to the Republic of Korea. According to the Federal Register document, the AIM-120C-8 is a refurbished version of AIM-120C-7, which is replaced some discontinued parts with equivalent commercial parts and its capabilities are identical to AIM-120C-7. This was the first time the C-8 version of AMRAAM has appeared in the US arms sales contract. Later, Japan, the Netherlands, the UAE and Spain received approval to purchase AIM-120C-8. Only Canada, the United Kingdom, Saudi Arabia, and Australia have been allowed to purchase the AIM-120D.

AGM-88 HARM

The AGM-88 HARM (High-speed Anti-Radiation Missile) is a tactical, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments. Description The AGM-88 can detect, attack and destroy a radar antenna or transmitter with minimal aircrew input. The proportional guidance system that homes in on enemy radar emissions has a fixed antenna and seeker head in the missile's nose. A smokeless, solid-propellant, booster-sustainer rocket motor propels the missile at speeds over Mach 2.0. The HARM missile was a program led by the U.S. Navy, and it was first carried by the A-6E, A-7, and F/A-18A/B aircraft, and then it equipped the EA-6B aircraft. RDT&E for use on the F-14 aircraft was begun, but not completed. The U.S. Air Force (USAF) put the HARM onto the F-4G Wild Weasel aircraft, and later on specialized F-16s equipped with the HARM Targeting System (HTS). The HTS pod, used by the USAF only, allows F-16s to detect and automatically target radar systems with HARMs instead of relying on the missile's sensors alone. History Deployment The HARM missile was approved for full production in March 1983, obtained initial operating capability (IOC) on the A-7E Corsair II in late 1983 and then deployed in late 1985 with VA-46 aboard the aircraft carrier USS America. In 1986, the first successful firing of the HARM from an EA-6B was performed by VAQ-131. It was soon used in combat—in March 1986 against a Libyan SA-5 site in the Gulf of Sidra, and then during Operation Eldorado Canyon in April. HARM was used extensively by the Navy, Marine Corps, and the Air Force in Operation Desert Storm during the Persian Gulf War of 1991. During the Gulf War, the HARM was involved in a friendly fire incident when the pilot of an F-4G Wild Weasel escorting a B-52G bomber mistook the latter's tail gun radar for an Iraqi AAA site. (This was after the tail gunner of the B-52 had targeted the F-4G, mistaking it for an Iraqi MiG.) The F-4 pilot launched the missile and then saw that the target was the B-52, which was hit. It survived with shrapnel damage to the tail and no casualties. The B-52 (serial number 58-0248) was subsequently renamed In HARM's Way. "Magnum" is spoken over the radio to announce the launch of an AGM-88. During the Gulf War, if an aircraft was illuminated by enemy radar a bogus "Magnum" call on the radio was often enough to convince the operators to power down. This technique would also be employed in Yugoslavia during air operations in 1999. In 2013 President Obama offered the AGM-88 to Israel for the first time. AGM-88E AARGM A newer upgrade, the AGM-88E Advanced Antiradiation Guided Missile (AARGM), features the latest software, enhanced capabilities intended to counter enemy radar shutdown, and passive radar using an additional active millimeter-wave seeker. It was released in November 2010, and it is a joint venture by the US Department of Defense and the Italian Ministry of Defense, produced by Orbital ATK. In November 2005, the Italian Ministry of Defense and the U.S. Department of Defense signed a Memorandum of Agreement on the joint development of the AGM-88E AARGM missile. Italy was providing $20 million of developmental funding as well as several million dollars worth of material, equipment, and related services. The Italian Air Force was expected to buy up to 250 missiles for its Tornado ECR aircraft. A flight test program was set to integrate the AARGM onto Tornado ECR's weapon system. The U.S. Navy demonstrated the AARGM's capability during Initial Operational Test and Evaluation (IOT&E) in spring 2012 with live firing of 12 missiles. Aircrew and maintenance training with live missiles was completed in June. The Navy authorized Full-Rate Production (FRP) of the AARGM in August 2012, with 72 missiles for the Navy and nine for the Italian Air Force to be delivered in 2013. A U.S. Marine Corps F/A-18 Hornet squadron will be the first forward-deployed unit with the AGM-88E. In September 2013, ATK delivered the 100th AARGM to the U.S. Navy. The AGM-88E program is on schedule and on budget, with Full Operational Capability (FOC) planned for September 2014. The AGM-88E was designed to improve the effectiveness of legacy HARM variants against fixed and relocatable radar and communications sites, particularly those that would shut down to throw off anti-radiation missiles, by attaching a new seeker to the existing Mach 2-capable rocket motor and warhead section, adding a passive anti-radiation homing receiver, satellite and inertial navigation system, a millimeter-wave radar for terminal guidance, and the ability to beam up images of the target via a satellite link just seconds before impact. This model of the HARM will be integrated onto the F/A-18C/D, F/A-18E/F, EA-18G, and Tornado ECR aircraft, and later on the F-35 (externally). In September 2015, the AGM-88E successfully hit a mobile ship target in a live-fire test, demonstrating the missile's ability to use antiradiation homing and millimeter-wave radar to detect, identify, locate, and engage moving targets. In December 2019, the German Air Force ordered the AARGM. On August 4, 2020, Northrop Grumman's Alliant Techsystems Operations division, based in Northridge, California, was awarded a $12,190,753 IDIQ contract for AARGM depot sustainment support, guidance section and control section repair, and equipment box test and inspection. On August 31, 2020, the same Northrop Grumman division was allocated roughly $80.9 million to develop new technology for the AARGM. Neither contract was awarded in free, open competition. AGM-88F HCSM Although the US Navy/Marine Corps chose the Orbital ATK-produced AGM-88E AARGM, Raytheon developed its own update of the HARM called the AGM-88F HCSM (HARM Control Section Modification), tested in conjunction with and ultimately for the US Air Force. It incorporates similar upgrade features as the AARGM, and although it is not yet listed for export, existing HARM users have shown interest. AGM-88G AARGM-ER The Navy's FY 2016 budget included funding for an extended range AARGM-ER that uses the existing guidance system and warhead of the AGM-88E with a solid integrated rocket-ramjet for double the range. In September 2016, Orbital ATK unveiled its extended-range AARGM-ER, which incorporates a redesigned control section and rocket motor for twice the range and internal carriage on the Lockheed Martin F-35A and F-35C Lightning II; internal carriage on the F-35B isn't possible due to internal space limitations. The new missile utilizes the AARGM's warhead and guidance systems in a new airframe that replaces the mid-body wings with aerodynamic strakes along the sides with control surfaces relocated to low-drag tail surfaces and a more powerful propulsion system for greater speed and range. It reportedly double the range and speed of AGM-88E which would result in the AGM-88G's range being around 300 km and speed of Mach 4. The U.S. Navy awarded Orbital ATK a contract for AARGM-ER development in January 2018. The USAF later joined the AARGM-ER program, involved in internal F-35A/F-35C integration work, and selected the AARGM-ER to serve as the basis for their land-attack Stand in Attack Weapon (SiAW). The AARGM-ER received Milestone-C approval in August 2021, and the first low-rate initial production contract was awarded the next month; initial operational capability is planned for 2023.

AGM-65 Maverick

The AGM-65 Maverick is an air-to-ground missile (AGM) designed for close air support. It is the most widely produced precision-guided missile in the Western world, and is effective against a wide range of tactical targets, including armor, air defenses, ships, ground transportation and fuel storage facilities. Development began in 1966 at Hughes as the first missile to use an electronic contrast seeker. It entered service with the United States Air Force in August 1972. Since then, it has been exported to more than 30 countries and is certified on 25 aircraft. The Maverick served during the Vietnam, Yom Kippur, Iran–Iraq, and Persian Gulf Wars, along with other smaller conflicts, destroying enemy forces and installations with varying degrees of success. Since its introduction into service, numerous Maverick versions had been designed and produced using electro-optical, laser, and imaging infrared guidance systems. The AGM-65 has two types of warhead: one has a contact fuze in the nose, the other has a heavyweight warhead fitted with a delayed-action fuze, which penetrates the target with its kinetic energy before detonating. The missile is currently produced by Raytheon Missile Systems. The Maverick shares the same configuration as Hughes's AIM-4 Falcon and AIM-54 Phoenix, and measures more than in length and in diameter. Development The Maverick's development history began in 1965, when the United States Air Force (USAF) began a program to develop a replacement to the AGM-12 Bullpup. With a range of , the radio-guided Bullpup was introduced in 1959 and was considered a "silver bullet" by operators. However, the launch aircraft was required to fly straight towards the target during the missile's flight instead of performing evasive maneuvers, thus risking the crew. Even when it hit, the small warhead was only useful against small targets like bunkers, when used against larger targets like the Thanh Hóa Bridge it did little other than char the structure. The USAF began a series of projects to replace Bullpup, both larger versions of Bullpup, models C and D, as well as a series of Bullpup adaptations offering fire-and-forget guidance. Among the latter were the AGM-83 Bulldog, AGM-79 Blue Eye and AGM-80 Viper. From 1966 to 1968, Hughes Missile Systems Division and Rockwell competed for the contract to build an entirely new fire-and-forget missile with far greater range performance than any of the Bullpup versions. Each were allocated $3 million for preliminary design and engineering work of the Maverick in 1966. In 1968, Hughes emerged with the $95 million contract for further development and testing of the missile; at the same time, contract options called for 17,000 missiles to be procured. Hughes conducted a smooth development of the AGM-65 Maverick, with the first unguided test launch from an F-4 on 18 September 1969, with the first guided test on 18 December successfully performing a direct hit on a M41 tank target at the Air Force Missile Development Center at Holloman Air Force Base, New Mexico. In July 1971, the USAF and Hughes signed a $69.9 million contract for 2,000 missiles, the first of which was delivered in 1972. Although early operational results were favorable, military planners predicted that the Maverick would fare less successfully in the hazy conditions of Central Europe, where it would have been used against Warsaw Pact forces. As such, development of the AGM-65B "Scene Magnified" version began in 1975 before it was delivered during the late 1970s. When production of the AGM-65A/B was ended in 1978, more than 35,000 missiles had been built. More versions of the Maverick appeared, among which was the laser-guided AGM-65C/E. Development of the AGM-65C started in 1978 by Rockwell, who built a number of development missiles for the USAF. Due to high cost, the version was not procured by the USAF, and instead entered service with the United States Marine Corps (USMC) as the AGM-65E. Another major development was the AGM-65D, which employed an imaging infrared (IIR) seeker. By imaging on radiated heat, the IIR is all-weather operable as well as showing improved performance in acquiring and tracking the hot engines, such as in tanks and trucks, that were to be one of its major missions. The seekerhead mechanically scanned the scene over a nitrogen-cooled 4-by-4 pixel array using a series of mirrored facets machined into the inner surface of the ring-shaped main gyroscope. The five-year development period of the AGM-65D started in 1977 and ended with the first delivery to the USAF in October 1983. The version received initial operating capability in February 1986. The AGM-65F is a hybrid Maverick combining the AGM-65D's IIR seeker and warhead and propulsion components of the AGM-65E. Deployed by the United States Navy (USN), the AGM-65F is optimized for maritime strike roles. The first AGM-65F launch from the P-3C took place in 1989, and in 1994, the USN awarded Unisys a contract to integrate the version with the P-3C. Meanwhile, Hughes produced the AGM-65G, which essentially has the same guidance system as the D, with some software modifications that track larger targets. In the mid-1990s to early 2000s, there were several ideas of enhancing the Maverick's potential. Among them was the stillborn plan to incorporate the Maverick millimeter wave active radar homing, which can determine the exact shape of a target. Another study called "Longhorn Project" was conducted by Hughes, and later Raytheon following the absorption of Hughes into Raytheon, looked a Maverick version equipped with turbojet engines instead of rocket motors. The "Maverick ER", as it was dubbed, would have a "significant increase in range" compared to the Maverick's current range of . The proposal was abandoned, but if the Maverick ER had entered production, it would have replaced the AGM-119B Penguin carried on the MH-60R. The most modern versions of the Maverick are the AGM-65H/K, which were in production . The AGM-65H was developed by coupling the AGM-65B with a charge-coupled device (CCD) seeker optimized for desert operations and which has three times the range of the original TV-sensor; a parallel USN program aimed at rebuilding AGM-65Fs with newer CCD seekers resulted in the AGM-65J. The AGM-65K, meanwhile, was developed by replacing the AGM-65G's IR guidance system with an electro-optical television guidance system. Design The Maverick has a modular design, allowing for different combinations of the guidance package and warhead to be attached to the rocket motor to produce a different weapon. It has long-chord delta wings and a cylindrical body, reminiscent of the AIM-4 Falcon and the AIM-54 Phoenix. Different models of the AGM-65 have used electro-optical, laser, and imaging infrared guidance systems. The AGM-65 has two types of warhead: one has a contact fuze in the nose, the other has a heavyweight warhead fitted with a delayed-action fuze, which penetrates the target with its kinetic energy before detonating. The latter is most effective against large, hard targets. The propulsion system for both types is a solid-fuel rocket motor behind the warhead. The Maverick missile is unable to lock onto targets on its own; it has to be given input by the pilot or weapon systems officer (WSO) after which it follows the path to the target autonomously. In an A-10 Thunderbolt II, for example, the video feed from the seeker head is relayed to a screen in the cockpit, where the pilot can check the locked target of the missile before launch. A crosshair on the heads-up display is shifted by the pilot to set the approximate target, where the missile will then automatically recognize and lock on to the target. Once the missile is launched, it requires no further assistance from the launch vehicle and tracks its target automatically. This fire-and-forget property is not shared by the E version that uses semi-active laser homing. Variants Maverick A is the basic model and uses an electro-optical television guidance system. No longer in U.S. service. Maverick B is similar to the A model, although the B model added optical zooming to lock onto small or distant targets. Maverick C was to be a laser-guided variant for the United States Marine Corps (USMC). It was canceled before production, however its requirement was later met by the Maverick E. Maverick D replaced the electro-optical guidance with an imaging infrared system which doubled the practical firing distance and allowed for its use at night and during bad weather. A reduced smoke rocket engine was also introduced in this model. It achieved its initial operation capability in 1983. Maverick E uses a laser designator guidance system optimized for fortified installations using a delayed fuse combined with a heavier penetrating blast-fragmentation warhead ( vs. in older models) that perforates a target with its kinetic energy before detonation. It achieved IOC in 1985 and was used mainly by USMC aviation. Maverick F, designed specially for United States Navy, it uses a modified Maverick D infrared guidance system optimized for tracking ships fitted onto a Maverick-E body and warhead. Maverick G model essentially has the same guidance system as the D with some software modification that enables the pilot to track larger targets. The G model's major difference is its heavier penetrator warhead taken from the Maverick E, compared to the D model's shaped-charge warhead. It completed tests in 1988. Maverick H model is an AGM-65B/D missile upgraded with a new charge-coupled device (CCD) seeker better suited for the desert environment. Maverick J model is a Navy AGM-65F missile upgraded with the new CCD seeker. However, this conversion is not confirmed. Maverick K model is an AGM-65G upgraded with the CCD seeker; at least 1,200, but possibly up to 2,500 AGM-65G rounds are planned for conversion to AGM-65K standard. Maverick E2/L model incorporates a laser-guided seeker that allows for designation by the launch aircraft, another aircraft, or a ground source and can engage small, fast moving, and maneuvering targets on land and at sea. Deployment The Maverick was declared operational on 30 August 1972 with the F-4D/Es and A-7s initially cleared for the type; the missile made its combat debut four months later with the USAF in the Vietnam War. During the Yom Kippur War in October 1973, the Israelis used Mavericks to destroy and disable enemy vehicles. Deployment of early versions of the Mavericks in these two wars were successful due to the favorable atmospheric conditions that suited the electro-optical TV seeker. Ninety-nine missiles were fired during the two wars, eighty-four of which were successful.. The Maverick was used for trials with the BGM-34A unmanned aerial vehicle in 1972–1973. Targeting could be carried out with a TV camera in the nose of the UAV. or using the seeker of an AGM-45 Shrike anti-radar missile also carried by the UAV to locate the target for the Maverick's camera to lock on to. In June 1975, during a border confrontation, a formation of Iranian F-4E Phantoms destroyed a group of Iraqi tanks by firing 12 Mavericks at them. Five years later, during Operation Morvarid as part of the Iran–Iraq War, Iranian F-4s used Mavericks to sink three Osa II missile boats and four P-6 combat ships. Due to weapons embargoes, Iran had to equip its AH-1J SeaCobra helicopters with AGM-65 Maverick missiles and used them with some success in various operations such as Operation Fatholmobin wherein Iranian AH-1Js fired 11 Mavericks. In August 1990, Iraq invaded Kuwait. In early 1991, the US-led Coalition executed Operation Desert Storm during which Mavericks played a crucial role in the ousting of Iraqi forces from Kuwait. Employed by F-15E Strike Eagles, F/A-18 Hornets, AV-8B Harriers, F-16 Fighting Falcons and A-10 Thunderbolt IIs, but used mainly by the last two, more than 5,000 Mavericks were used to attack armored targets. The most-used variant by the USAF was the IIR-guided AGM-65D. The reported hit rate by USAF Mavericks was 80–90%, while for the USMC it was 60%. The Maverick was used again in Iraq during the 2003 Iraq War, during which 918 were fired. The first time the Maverick were fired from a Lockheed P-3 Orion at a hostile vessel was when the USN and coalition units came to the aid of Libyan rebels to engage the Libyan Coast Guard vessel Vittoria in the port of Misrata, Libya, during the late evening of 28 March 2011. Vittoria was engaged and fired upon by a USN P-3C Maritime Patrol aircraft with AGM-65 Maverick missiles.

AIM-54 Phoenix

The AIM-54 Phoenix is an American radar-guided, hypersonic, long-range air-to-air missile (AAM), carried in clusters of up to six missiles on the Grumman F-14 Tomcat, its only operational launch platform. The Phoenix was the United States' only long-range air-to-air missile. The combination of Phoenix missile and the AN/AWG-9 guidance radar was the first aerial weapons system that could simultaneously engage multiple targets. Due to its active radar tracking, the brevity code "Fox Three" was used when firing the AIM-54. Both the missile and the aircraft were used by Iran and the United States Navy. In US service both are now retired, the AIM-54 Phoenix in 2004 and the F-14 in 2006. They were replaced by the shorter-range AIM-120 AMRAAM, employed on the F/A-18 Hornet and F/A-18E/F Super Hornet—in its AIM-120D version, the latest version of the AMRAAM just matches the Phoenix's maximum range. The AIM-54 is credited with 62 air-to-air kills, all scored by Iran during the eight-year Iran–Iraq War. Following the retirement of the F-14 by the U.S. Navy, the weapon's only current operator is the Islamic Republic of Iran Air Force. Development Background Since 1951, the Navy faced the initial threat from the Tupolev Tu-4K 'Bull' carrying anti-ship missiles or nuclear bombs. Eventually, during the height of the Cold War, the threat would have expanded into regimental-size raids of Tu-16 Badger and Tu-22M Backfire bombers equipped with low-flying, long-range, high-speed, nuclear-armed cruise missiles and considerable electronic countermeasures (ECM) of various types. This combination was considered capable of saturating fleet defenses and threatening carrier groups. The Navy would require a long-range, long-endurance interceptor aircraft to defend carrier battle groups against this threat. The proposed F6D Missileer was intended to fulfill this mission and oppose the attack as far as possible from the fleet it was defending. The weapon needed for interceptor aircraft, the Bendix AAM-N-10 Eagle, was to be an air-to-air missile of unprecedented range when compared to contemporary AIM-7 Sparrow missiles. It would work together with Westinghouse AN/APQ-81 radar. The Missileer project was cancelled in December 1960. AIM-54 In the early 1960s, the U.S. Navy made the next interceptor attempt with the F-111B, and they needed a new missile design. At the same time, the USAF canceled the projects for their land-based high-speed interceptor aircraft, the North American XF-108 Rapier and the Lockheed YF-12, and left the capable AIM-47 Falcon missile at a quite advanced stage of development, but with no effective launch platform. The AIM-54 Phoenix, developed for the F-111B fleet air defense fighter, had an airframe with four cruciform fins that was a scaled-up version of the AIM-47. One characteristic of the Missileer ancestry was that the radar sent it mid-course corrections, which allowed the fire control system to "loft" the missile up over the target into thinner air where it had better range. The F-111B was canceled in 1968. Its weapons system, the AIM-54 working with the AWG-9 radar, migrated to the new U.S. Navy fighter project, the VFX, which would later become the F-14 Tomcat. In 1977, development of a significantly improved Phoenix version, the AIM-54C, was developed to better counter projected threats from tactical anti-naval aircraft and cruise missiles, and its final upgrade included a re-programmable memory capability to keep pace with emerging ECM. Usage in comparison to other weapon systems The AIM-54/AWG-9 combination had multiple track capability (up to 24 targets) and launch (up to six Phoenixes can be launched nearly simultaneously); the large missile is equipped with a conventional warhead. On the F-14, four missiles can be carried under the fuselage tunnel attached to special aerodynamic pallets, plus two under glove stations. A full load of six Phoenix missiles and the unique launch rails weighs in at over , about twice the weight of Sparrows, putting it above the allowable bringback load (which also would include enough fuel for go-around attempts). As such, carrying six Phoenix missiles would necessitate the jettison of at least some of the Phoenix missiles if they were not used. The most common air superiority payload was a mix of two Phoenix, four Sparrow, and two Sidewinder missiles. Most other US aircraft relied on the smaller, semi-active medium-range AIM-7 Sparrow. Semi-active guidance meant the aircraft no longer had a search capability while supporting the launched Sparrow, reducing situational awareness. The Tomcat's radar could track up to 24 targets in track-while-scan mode, with the AWG-9 selecting up to six potential targets for the missiles. The pilot or radar intercept officer (RIO) could then launch the Phoenix missiles once parameters were met. The large tactical information display (TID) in the RIO's cockpit gave information to the aircrew (the pilot had the ability to monitor the RIO's display) and the radar could continually search and track multiple targets after Phoenix missiles were launched, thereby maintaining situational awareness of the battlespace. The Link 4 datalink allowed US Navy Tomcats to share information with the E-2C Hawkeye AEW aircraft. During Desert Shield in 1990, the Link 4A was introduced; this allowed the Tomcats to have a fighter-to-fighter datalink capability, further enhancing overall situational awareness. The F-14D entered service with JTIDS that brought the even better Link 16 datalink "picture" to the cockpit. Active guidance The Phoenix has several guidance modes and achieves its longest range by using mid-course updates from the F-14A/B AWG-9 radar (APG-71 radar in the F-14D) as it climbs to cruise between and at close to Mach 5. The Phoenix uses this high altitude to maximize its range by reducing atmospheric drag. At around from the target, the missile activates its own radar to provide terminal guidance. Minimum engagement range for the Phoenix is around ; at this range active homing would initiate upon launch. Service history U.S. combat experience On January 5, 1999, a pair of US F-14s fired two Phoenixes at Iraqi MiG-25s southeast of Baghdad. Both AIM-54s' rocket motors failed and neither missile hit its target. On September 9, 1999, another US F-14 launched an AIM-54 at an Iraqi MiG-23 that was heading south into the no-fly zone from Al Taqaddum air base west of Baghdad. The missile missed, eventually going into the ground after the Iraqi fighter reversed course and fled north. The AIM-54 Phoenix was retired from USN service on September 30, 2004. F-14 Tomcats were retired on September 22, 2006. They were replaced by shorter-range AIM-120 AMRAAMs, employed on the F/A-18E/F Super Hornet. Despite the much-vaunted capabilities, the Phoenix was rarely used in combat, with only two confirmed launches and no confirmed targets destroyed in US Navy service. The USAF F-15 Eagle had responsibility for overland combat air patrol duties in Operation Desert Storm in 1991, primarily because of the onboard F-15 IFF capabilities. The Tomcat did not have the requisite IFF capability mandated by the JFACC to satisfy the rules of engagement to utilize the Phoenix capability at beyond visual range. The AIM-54 was not adopted by any foreign nation besides Iran, or any other US armed service, and was not used on any aircraft other than the F-14. Iranian combat experience On January 7, 1974 as part of Project Persian King, the Imperial Iranian Air Force placed an order for 424 AIM-54As, later increasing it by 290 missiles that June. Of the initial order, 274 missiles and 10 training rounds were delivered for US$150 million, until the 1979 Revolution ended deliveries and left the remaining 150 missiles embargoed and the additional order of 290 cancelled. According to Tom Cooper and Farzad Bishop, during the Iran-Iraq War AIM-54s fired by IRIAF Tomcats achieved 78 victories against Iraqi MiG-21/23/25s, Tu-22s, Su-20/22s, Mirage F 1s, Super Étendards, and even two AM-39 Exocets and a C-601. This includes two occasions where one AIM-54 was responsible for the downing of two Iraqi aircraft, as well as an incident on January 7, 1981 where a Phoenix fired at a four-ship of MiG-23s downed three and damaged the fourth. The US refused to supply spare parts and maintenance after the 1979 Revolution, except for a brief period during the Iran-Contra Affair. According to Cooper, the Islamic Republic of Iran Air Force kept its F-14 fighters and AIM-54 missiles in regular use during the entire Iran–Iraq War, though periodic lack of spares grounded large parts of the fleet at times. During late 1987, the stock of AIM-54 missiles was at its lowest, with fewer than 50 operational missiles available. The missiles needed fresh thermal batteries that could only be purchased from the US. Iran found a clandestine buyer that supplied it with batteries, which cost up to US$10,000 each. Iran received spares and parts for both the F-14s and AIM-54s from various sources during the Iran–Iraq War, and has received more spares after the conflict. Iran started a program to build spares for the planes and missiles, and although there are claims that it no longer relies on outside sources to keep its F-14s and AIM-54s operational, there is evidence that Iran continues to procure parts clandestinely. Both the F-14 Tomcat and AIM-54 Phoenix missile continue in the service of the Islamic Republic of Iran Air Force. Iran claimed to be working on building an equivalent missile and in 2013 unveiled the Fakour-90, an upgraded and reverse-engineered version of the Phoenix. Variants Original model that became operational with the U.S. Navy in about 1974, and it was also exported to Iran before the Iran hostage crisis beginning in 1979. Also known as the 'Dry' missile. A version with simplified construction and no coolant conditioning. Did not enter series production. Developmental work started in January 1972. 7 X-AIM-54B missiles were created for testing, 6 of them by modifying pilot production IVE/PIP rounds. After two successful test firings, the 'Dry' missile effort was cancelled for being "not cost effective". The only improved model that was ever produced. It used digital electronics in the place of the analog electronics of the AIM-54A. This model had better abilities to shoot down low and high-altitude antiship missiles. This model took over from the AIM-54A beginning in 1986. /sealed round More capabilities in electronic counter-countermeasures. It did not require coolant during flight. The Missile was deployed from 1988 onwards. Because the AIM-54 ECCM/Sealed received no coolant, F-14s carrying this version of the missile could not exceed a specified airspeed. There were also test, evaluation, ground training, and captive air training versions of the missile; designated ATM-54, AEM-54, DATM-54A, and CATM-54. The flight versions had A and C versions. The DATM-54 was not made in a C version as there was no change in the ground handling characteristics. A 1970s proposal for a ship launched version of the Phoenix as an alternative/replacement for the Sea Sparrow point defense system. It would also have provided a medium-range SAM capability for smaller and/or non-Aegis equipped vessels (such as the CVV). The Sea Phoenix system would have included a modified shipborne version of the AN/AWG-9 radar. Hughes Aircraft touted the fact that 27 out of 29 major elements of the standard (airborne) AN/AWG-9 could be used in the shipborne version with little modification. Each system would have consisted of one AWG-9 radar, with associated controls and displays, and a fixed 12-cell launcher for the Phoenix missiles. In the case of an aircraft carrier, for example, at least three systems would have been fitted in order to give overlapping coverage throughout the full 360°. Both land and ship based tests of modified Phoenix (AIM-54A) missiles and a containerised AWG-9 (originally the 14th example off the AN/AWG-9 production line) were successfully carried out from 1974 onwards. AIM-54B A land based version for the USMC was also proposed. It has been suggested that the AIM-54B would have been used in operational Sea Phoenix systems, although that version had been cancelled by the second half of the 1970s. Ultimately, a mix of budgetary and political issues meant that, despite being technically and operationally attractive, further development of the Sea Phoenix did not proceed. In February 2013 Iran reportedly tested an indigenous long-range air-to-air missile. In September 2013 it displayed the Fakour-90 on a military parade. It looked almost identical to the AIM-54 Phoenix. In July 2018 as reported by Jane's, Iran started mass production of the Fakour-90.

Lockheed AC-130

The Lockheed AC-130 gunship is a heavily armed, long-endurance, ground-attack variant of the C-130 Hercules transport, fixed-wing aircraft. It carries a wide array of ground-attack weapons that are integrated with sophisticated sensors, navigation, and fire-control systems. Unlike other modern military fixed-wing aircraft, the AC-130 relies on visual targeting. Because its large profile and low operating altitudes around 7,000 feet (2,100 m) make it an easy target, its close air support missions are usually flown at night. The airframe is manufactured by Lockheed Martin, while Boeing is responsible for the conversion into a gunship and for aircraft support. Developed during the Vietnam War as "Project Gunship II", the AC-130 replaced the Douglas AC-47 Spooky, or "Gunship I". The sole operator is the United States Air Force, which uses the AC-130U Spooky and AC-130W Stinger II variants for close air support, air interdiction, and force protection, with the upgraded AC-130J Ghostrider entering service. Close air support roles include supporting ground troops, escorting convoys, and urban operations. Air-interdiction missions are conducted against planned targets and targets of opportunity. Force-protection missions include defending air bases and other facilities. AC-130Us are based at Hurlburt Field, Florida, while AC-130Ws are based at Cannon AFB, New Mexico; gunships can be deployed worldwide. The squadrons are part of the Air Force Special Operations Command (AFSOC), a component of the United States Special Operations Command. The AC-130 has an unpressurized cabin, with the weaponry mounted to fire from the port side of the fuselage. During an attack, the gunship performs a pylon turn, flying in a large circle around the target, therefore being able to fire at it for far longer than in a conventional strafing attack. The AC-130H Spectre was armed with two M61 Vulcan cannons, one L60 Bofors 40 mm cannon, and M137 cannon and M37 recoil mechanism from the M102 howitzer; after 1994, the cannons were removed. The upgraded AC-130U Spooky has a single GAU-12 Equalizer cannon in place of the Spectre's two cannons, an improved fire-control system, and increased ammunition capacity. The new AC-130J was based on the MC-130J Commando II special-operations tanker. The AC-130W Stinger II is a modified C-130H with upgrades including a precision strike package. Development Origins During the Vietnam War, the C-130 Hercules was selected to replace the Douglas AC-47 Spooky gunship (Project Gunship I) to improve mission endurance and increase capacity to carry munitions. Capable of flying faster than helicopters and at high altitudes with excellent loiter time, the use of the pylon turn allowed the AC-47 to deliver continuous, accurate fire to a single point on the ground. In 1967, JC-130A 54-1626 was selected for conversion into the prototype AC-130A gunship (Project Gunship II). The modifications were done at Wright-Patterson Air Force Base by the Aeronautical Systems Division. A direct-view night-vision telescope was installed in the forward door, an early forward-looking infrared device was placed in the forward part of the left wheel well, with miniguns and rotary cannons fixed facing down and aft along the left side. The analog fire-control computer prototype was handcrafted by RAF Wing Commander Tom Pinkerton at the USAF Avionics Laboratory at Wright-Patterson AFB. Flight testing of the prototype was performed primarily at Eglin Air Force Base, followed by further testing and modifications. By September 1967, the aircraft was certified ready for combat testing and was flown to Nha Trang Air Base, South Vietnam for a 90-day test program. The AC-130 was later supplemented by the AC-119 Shadow (Project Gunship III), which later proved to be underpowered. Seven more warplanes were converted to the "Plain Jane" configuration like the AC-130 prototype in 1968, and one aircraft received the "Surprise Package" refit in 1969. The Surprise Package upgrade included the latest 20 mm rotary autocannons and 40 mm Bofors cannon, but no 7.62 mm close-support armament. The Surprise Package configuration served as a test bed for the avionic systems and armament for the AC-130E. In 1970, 10 more AC-130As were acquired under the "Pave Pronto" project. In the summer of 1971, Surprise Package AC-130s were converted to the Pave Pronto configuration and assumed the new nickname of "Thor". Conversion of C-130Es into AC-130Es for the "PAVE Spectre" project followed. Regardless of their project names, the aircraft were more commonly referred to by the squadron's call sign, Spectre. Recent and planned upgrades In 2007, AFSOC initiated a program to upgrade the armament of AC-130s. The test program planned for the 25 mm GAU-12/U and 40 mm Bofors cannon on the AC-130U gunships to be replaced with two 30 mm Mk 44 Bushmaster II cannons. In 2007, the Air Force modified four AC-130U gunships as test platforms for the Bushmasters. These were referred to as AC-130U Plus 4 or AC-130U+4. AFSOC, however, cancelled its plans to install the new cannons on its fleet of AC-130Us. It has since removed the guns and reinstalled the original 40 mm and 25 mm cannons and returned the planes to combat duty. Brigadier General Bradley A. Heithold, AFSOC's director of plans, programs, requirements, and assessments, said on 11 August 2008 that the effort was canceled because of problems with the Bushmaster's accuracy in tests "at the altitude we were employing it". Also, schedule considerations drove the decision, he said. Plans were made to possibly replace the 105 mm cannon with a breech-loading 120 mm M120 mortar, and to give the AC-130 a standoff capability using either the AGM-114 Hellfire missile, the Advanced Precision Kill Weapon System (based on the Hydra 70 rocket), or the Viper Strike glide bomb. In 2010, the Air Force awarded L-3 Communications a $61 million contract to add precision strike packages to eight MC-130W Combat Spear special-mission aircraft to give them a gunship-like attack capability; such-equipped MC-130Ws are known as Dragon Spears. AFSOC is arming these aircraft to relieve the high operational demands on AC-130 gunships until new AC-130Js enter service. The MC-130W Dragon Spear was renamed AC-130W Stinger II in 2011. The precision strike packages consist of a 30 mm gun and several precision guided munitions. Rails are mounted on the outboard pylon of the wing for four Hellfire missiles, SDBs, or SDB IIs under each. Ten Common Launch Tubes (CLTs) are mounted on the rear ramp to fire Griffin A missiles; additional missiles are stored in the aircraft that can be reloaded in flight. CLTs are able to fire other small munitions able to fit inside the -diameter, -long tubes. The Air Force launched an initiative in 2011 to acquire 16 new gunships based on newly built MC-130J Combat Shadow II special-operations tankers outfitted with a "precision strike package" to give them an attack capability, requesting $1.6 billion from fiscal years 2011 through 2015. This was to increase the size of the gunship fleet to 33 aircraft, a net increase of eight after the planned retirement of eight aging AC-130Hs. The first aircraft would be bought in fiscal 2012, followed by two in fiscal 2013, five in fiscal 2014, and the final eight in fiscal 2015. The decision to retain the C-130 came after funding for 16 C-27Js was removed from the fiscal 2010 budget. The AC-130J will follow the path of the Dragon Spear program. On 9 January 2013, the Air Force began converting the first MC-130J Combat Shadow II into an AC-130J Ghostrider. The first AC-130J Ghostrider was delivered to AFSOC on 29 July 2015. The first AC-130J gunships achieved initial operational capability (IOC) on 30 September 2017. The AC-130J has two planned increments: the Block 10 configuration includes an internal 30 mm gun, small diameter bombs, and laser-guided missiles launched from the rear cargo door; and Block 20 configuration adds a 105 mm cannon, large aircraft infrared countermeasures, wing-mounted Hellfire missiles, and radio-frequency countermeasures. The Air Force decided to add a 105 mm cannon to the AC-130J in addition to the 30 mm cannon and smart bombs, the shells being more accurate and cheaper than dropping SDBs. AFSOC is actively pursuing a directed-energy weapon on board the AC-130J in place of the 30 mm gun by 2022, similar to the previous Advanced Tactical Laser program. It is to produce a beam of up to 120 kW, or potentially even 180–200 kW, weigh about , defensively destroy antiaircraft missiles, and offensively engage communications towers, boats, cars, and aircraft. However, laser armament may only be installed on a few aircraft rather than the entire AC-130J fleet; the laser will be mounted on the side in place of the 30 mm cannon. Other potential additions include an active denial system to perform airborne crowd control, and small unmanned aerial vehicles from the common launch tubes to provide remote video feed and coordinates to weapons operators through cloud cover. Called the Tactical Off-board Sensor (TOBS), the drones would be expendable and fly along a programmed orbit to verify targets the aircraft cannot see itself because of bad weather or standing off from air defenses. AFSOC will initially use the Raytheon Coyote small UAV for the TOBS mission, as it is an off-the-shelf design with a one-hour endurance, but plans to fulfill the role with a new drone capable of a four-hour endurance by 2019. The Air Force was also interested in acquiring a glide bomb that can be launched from the common launch tubes capable of hitting ground vehicles traveling as fast as 120 km/h (70 mph) while above . In June 2016, Dynetics was awarded a contract by SOCOM to integrate its tactical munition onto the AC-130. Designated the GBU-69/B Small Glide Munition, the weapon weighs and is armed with a blast-fragmentation warhead that can detonate by direct impact or at a selected height; despite being smaller, being unpowered allows for its warhead to be heavier than those on the Hellfire and Griffin A missiles, and , respectively. Guidance is provided by a GPS receiver with antispoofing software and four Distributed Aperture Semiactive Laser Seeker apertures adapted from the WGU-59/B APKWS for terminal guidance. Approval for fielding occurred in early 2017. Dynetics was awarded a contract to deliver an initial batch of 70 SGMs in June 2017, with plans to buy up to 1,000. The SGM can travel . Future , AC-130 gunships have been providing close air support for special operators for 50 years. Although the aircraft have been kept relevant through constant upgrades to their weaponry, sensor packages, and countermeasures, they are not expected to be survivable in future nonpermissive environments due to their high signatures and low airspeeds. Military analysts, such as the Center for Strategic and Budgetary Assessments, have suggested that AFSOC invest in more advanced technologies to fill the role to operate in future contested combat zones, including a mix of low-cost disposable unmanned and stealthy strike aircraft. Design Overview The AC-130 is a heavily armed, long-endurance aircraft carrying an array of antiground-oriented weapons that are integrated with sophisticated sensors, navigation, and fire-control systems. It is capable of delivering precision firepower or area-saturation fire over a target area over a long period of time, at night, or in adverse weather. The sensor suite consists of an electro-optical image sensor, infrared sensor, and radar. These sensors allow the gunship to visually or electronically identify friendly ground forces and targets in most weather conditions. The AC-130U is equipped with the AN/APQ-180, a synthetic aperture radar, for long-range target detection and identification. The gunship's navigational devices include inertial navigation systems and a global positioning system. The AC-130U employs technologies developed in the 1990s, which allow it to attack two targets simultaneously. It has twice the munitions capacity of the AC-130H. Although the AC-130U conducts some operations in daylight, most of its combat missions are conducted at night. The AC-130H's unit cost is US$132.4 million, and the AC-130U's cost is $190 million (fiscal 2001 dollars). Upgrades During the Vietnam War era, the various AC-130 versions following the Pave Pronto modifications were equipped with a magnetic anomaly detector system called Black Crow (designated AN/ASD-5), a highly sensitive passive device with a phased-array antenna located in the left-front nose radome that could pick up localized deviations in the Earth's magnetic field normally used to detect submerged submarines. The Black Crow system was slaved into the targeting computers of the AC-130A/E/H, enabling the detection of the unshielded ignition coils of North Vietnamese trucks hidden under dense jungle foliage along the Ho Chi Minh Trail. It could also detect hand-held transmitter signals of air controllers on the ground to identify and locate targets. The PGM-38/U enhanced 25 mm high-explosive incendiary round was created to expand the AC-130U gunships' mission in standoff range and survivability for its 25 mm GAU-12/U gun. This round is a combination of the existing PGU-25 HEI and a M758 fuze designated as FMU-151/B to meet the MIL-STD-1316. The FMU-151 has an improved arming delay with multisensitive range. Operational history Vietnam War The AC-130 gunship first arrived in South Vietnam on 21 September 1967 under the Gunship II program and began combat operations over Laos and South Vietnam that year. In June 1968, AC-130s were deployed to Tan Son Nhut AB near Saigon for support against the Tet Offensive. By 30 October 1968, enough AC-130 Gunship IIs arrived to form a squadron, the 16th Special Operations Squadron of the 8th Tactical Fighter Wing, at Ubon Royal Thai Air Force Base, Thailand. At this time, the C-130A gunship was designated the AC-130A. On 18 August 1968, an AC-130 gunship flying an armed reconnaissance mission in Vietnam's III Corps was diverted to support the Katum Special Forces Camp. The ground commander quickly assessed the accurate fire and capabilities of this weapons system and called for fire on his own perimeter when the Viet Cong attempted to bridge the wire on the west side of his position. By December 1968, most AC-130s flew under F-4 Phantom II escort (to protect the gunship against heavy and concentrated antiaircraft fire) from the 497th Tactical Fighter Squadron, normally three Phantoms per gunship. On 24 May 1969, the first Spectre gunship was lost to enemy fire. In late 1969, under code name "Surprise Package", 56-0490 arrived with solid-state, laser-illuminated, low light-level TV with a companion YAG laser designator, an improved forward-looking infrared (FLIR) sensor, video recording for TV and FLIR, an inertial navigation system, and a prototype digital fire-control computer. The remaining AC-130s were refitted with upgraded similar equipment in the summer of 1970, and then redeployed to Ubon RTAFB. On 25 October 1971, the first "Cadillac" gunship, the AC-130E, arrived in Vietnam. On 17 February 1972, the first 105 mm cannon arrived for service with Spectre and was installed on Gunship 570. It was used from mid-February until the aircraft received battle damage to its right flap. The cannon was switched to Gunship 571 and was used until 30 March when the aircraft was shot down. On 28 January 1973, the Vietnam peace accord went into effect, marking the end of Spectre operations in Vietnam. Spectre was still needed and active in the region, supporting operations in Laos and Cambodia. On 22 February 1973, American offensive operations in Laos ended and the gunships became totally committed to operations in the Cambodian conflict. On 12 April 1975, the Khmer Rouge was threatening the capital of Phnom Penh and AC-130s were called on to help in Operation Eagle Pull, the final evacuation of American and allied officials from Phnom Penh before it was conquered by the communists. The AC-130 was also over Saigon on 30 April 1975 to protect the final evacuation in Operation Frequent Wind. Spectres were also called in when the USS Mayaguez was seized, on the open sea, by Khmer Rouge soldiers and sailors on 15 May 1975. Six AC-130s and 52 air crew members were lost during the war. U.S. claimed AC-130s destroyed more than 10,000 trucks and participated in many crucial close-air-support missions in Vietnam. Cold War and later action With the conclusion of hostilities in Southeast Asia in the mid-1970s, the AC-130H became the sole gunship in the regular Air Force, home based at Hurlburt Field, Florida, while the AC-130A fleet was transferred to the Air Force Reserve's 919th Tactical Airlift Group (919 TAG) at Eglin AFB Auxiliary Field #3/Duke Field, Florida. With the transition to the AC-130A, the 919 TAG was then redesignated as the 919th Special Operations Group. In the late 1970s, when the AC-130H fleet was first being modified for in-flight refueling capability, a demonstration mission was planned and flown from Hurlburt Field, Florida, nonstop, to conduct a 2-hour live-fire mission over Empire Firing Range in the Republic of Panama, then return home. This 13-hour mission with two in-flight refuelings from KC-135 tankers proved the validity of flying long-range missions outside the contiguous United States to attack targets then return to home base without intermediate stops. AC-130s from both the 4th and 16th Special Operations Squadrons have been deployed in nearly every conflict in which the United States has been involved, officially and unofficially, since the end of the Vietnam War. In July 1979, AC-130H crews deployed to Howard Air Force Base, Panama, as a precaution against possible hostile actions against American personnel during the Nicaraguan Revolution. New time aloft and nonstop distance records were subsequently set by a 16th SOS two-ship AC-130H formation flight that departed Hurlburt Field on 13 November 1979 and landed on 15 November at Andersen Air Force Base, Guam, a distance of and 29 hours 43 minutes nonstop, refueling four times in-flight. Refueling support for the Guam deployment was provided by KC-135 crews from the 305th Air Refueling Wing from Grissom AFB, Indiana. In November 1979, four AC-130H gunships flew nonstop from Hurlburt Field to Anderson AFB, Guam, because of the hostage situation at the US Embassy in Iran. At Guam, AC-130H crews developed communications-out/lights-out refueling procedures for later employment by trial-and-error. This deployment with the 1 SOW/CC as task force commander was directed from the office of the CJCS for fear that Iranian militants could begin executing American Embassy personnel who had been taken hostage on 4 November. One early option considered AC-130H retaliatory punitive strikes deep within Iran. Later gunship flights exceeded the 1979 Hurlburt-to-Guam flight. Upon return in March 1980, the four planes soon found themselves in Egypt to support the ill-fated hostage rescue attempt. During Operation Urgent Fury in Grenada in 1983, AC-130s suppressed enemy air-defense systems and attacked ground forces enabling the assault of the Point Salines Airfield via airdrop and air-land of friendly forces. The AC-130 aircrew earned the Lieutenant General William H. Tunner Award for the mission. The AC-130Hs of the 16th Special Operations Squadron unit maintained an ongoing rotation to Howard AB, Panama, monitoring activities in El Salvador and other Central American points of interest, with rules of engagement eventually permitting attacks on FMLN targets. This commitment of maintainers and crews started in 1983 and lasted until 1990. The AC-130 is considered to have hastened the end of the Salvadoran Civil War in the 1980s. Crews flew undercover missions from Honduras and attacked guerrilla camps and concentrations. AC-130s also had a primary role during the United States invasion of Panama (named Operation Just Cause) in 1989, when they destroyed Panama Defense Force headquarters and numerous command-and-control facilities, and provided close air support for US ground troops. Aircrews earned the Mackay Trophy for the most meritorious flight of the year, and the Tunner Award. Gulf War and the 1990s During the Gulf War of 1990–91 (Operations Desert Shield and Desert Storm), Regular Air Force and Air Force Reserve AC-130s provided close air support and force protection (air base defense) for ground forces, and battlefield interdiction. The primary interdiction targets were early-warning/ground-control intercept sites along the southern border of Iraq. At its standard altitude of 12,000 feet, the aircraft had a proven ability to engage moving ground targets. The first gunship to enter the Battle of Khafji helped stop a southbound Iraqi armored column on 29 January 1991. One day later, three more gunships provided further aid to Marines participating in the operation. The gunships attacked Iraqi positions and columns moving south to reinforce their positions north of the city. Despite the threat of SAMs and increasing visibility during the early morning hours of 31 January 1991, one AC-130H, AF Serial No. 69-6567, call-sign Spirit 03, opted to stay to continue to protect the Marines. A lone Iraqi with a Strela-2 MANPADS shot Spirit 03 down, and all 14 crew members were killed. The loss of Spirit 03 did however result in the US DoD joining the development of the AN/AAQ-24 Directed Infrared Countermeasures System which, in its updated laser-based form, is now a common fit across large US military aircraft. The military has used AC-130 gunships during the humanitarian operations in Somalia (Operation Restore Hope and Operation United Shield) in 1992–93 and Operation Uphold Democracy in Haiti in 1994. AC-130s took part in Operation Assured Response in Liberia in 1996 and in Operation Silver Wake in 1997, the evacuation of American non-combatants from Albania. AC-130s took part in the NATO missions in Bosnia and Herzegovina and Kosovo during the 1990s. The AC-130U gunship set a new record for the longest sustained flight by any C-130 on 22 and 23 October 1997, when two AC-130U gunships flew 36 hours nonstop from Hurlburt Field to Taegu Air Base (Daegu), South Korea, being refueled seven times in the air by KC-135 tankers. The two gunships took on 410,000 lb (186,000 kg) of fuel. Gunships also were part of the buildup of US forces in 1998 to compel Iraq to allow UNSCOM weapons inspections. War on Terror The US has used gunships with deployments to the war in Afghanistan (Operation Enduring Freedom – Afghanistan) (2001–2016), and Iraq War (Operation Iraqi Freedom) (2003–2011). AC-130 strikes were directed by special forces on known Taliban locations during the early days of the war in Afghanistan. US Special Operations Forces are using the AC-130 to support its operations. The day after arriving in Afghanistan, the AC-130s attacked Taliban and Al-Qaeda forces near the city of Konduz and were directly responsible for the city's surrender the next day. On 26 November 2001, Spectres were called in to put down a rebellion at the prison fort of Qala-I-Janghi. The 16 SOS flew missions over Mazar-i-Sharif, Kunduz, Kandahar, Shkin, Asadabad, Bagram, Baghran, Tora Bora, and virtually every other part of Afghanistan. The Spectre participated in countless operations within Afghanistan, performing on-call close air support and armed reconnaissance. In March 2002, three AC-130 Spectres provided 39 crucial combat missions in support of Operation Anaconda in Afghanistan. During the intense fighting, the planes fired more than 1,300 40 mm and 1,200 105 mm rounds. Close air support was the main mission of the AC-130 in Iraq. Night after night, at least one AC-130 was in the air to fulfill one or more air-support requests (ASRs). A typical mission had the AC–130 supporting a single brigade's ASRs followed by aerial refueling and another two hours with another brigade or SOF team. The use of AC-130s in places like Fallujah, urban settings where insurgents were among crowded populations of non-combatants, was criticized by human rights groups. AC-130s were also used for intelligence gathering with their sophisticated long-range video, infrared and radar sensors. In 2007, US Special Operations forces also used the AC-130 in attacks on suspected Al-Qaeda militants in Somalia. Eight AC-130H and 17 AC-130U aircraft were in active-duty service as of July 2010. In March 2011, the Air Force deployed two AC-130U gunships to take part in Operation Odyssey Dawn, the US military intervention in Libya, which eventually came under NATO as Operation Unified Protector. By September 2013, 14 MC-130W Dragon Spear aircraft have been converted to AC-130W Stinger II gunships. The Stinger gunships have been deployed to Afghanistan to replace the aging AC-130H aircraft and provide an example for the new AC-130J Ghostrider. Modifications began by cutting holes in the plane to make room for weapons and adding kits and bomb bases for laser-guided munitions. Crews added a 105 mm cannon, 20-inch infrared and electro-optical sensors, and the ability to carry 250-lb bombs on the wings. The final AC-130H Spectre gunship, tail number 69-6569 "Excalibur" was retired on 26 May 2015 at Cannon Air Force Base, New Mexico. On 15 November 2015, two days after the attacks in Paris by ISIL, AC-130s and A-10 Thunderbolt II attack aircraft destroyed a convoy of over 100 ISIL-operated oil tanker trucks in Syria. The attacks were part of an intensification of the US-led Military intervention against ISIL called Operation Tidal Wave II (named after the original Operation Tidal Wave during World War II, a failed attempt to raid German oil fields that resulted in heavy aircraft and aircrew loss) in an attempt to cut off oil smuggling as a source of funding for the group. On 3 October 2015, an AC-130 mistakenly attacked the Doctors Without Borders hospital in Kunduz, Afghanistan, killing 42 people and injuring over 30. In five separate runs, the gunship struck the hospital, that was erroneously identified as the source of attacks on coalition members. Subsequent inquiries led to punishment of 16 military personnel and cited "human error" as the root cause. On 30 September 2017, the Air Force declared the AC-130J Ghostrider had achieved initial operational capability, with six gunships having been delivered; the aircraft is planned to reach full operational capability by 2023 with 37 gunships delivered. The J-variant is lighter and more fuel efficient than previous versions, able to fly at with a range of and service ceiling of . The AC-130U returned from its final combat deployment on 8 July 2019; the final AC-130U was retired in August 2019. AFSOC started taking delivery of the AC-130J in spring 2019, and the aircraft began deploying to Afghanistan by the summer.

This aircraft was a conversion of the first production C-130. On 25 March 1971, it took an anti-aircraft artillery hit in the belly just aft of the nose gear wheel well over the Ho Chi Minh trail in Laos. The 37 mm shell destroyed everything below the crew deck and barely missed striking two crew members. The pilot was able to crash land the aircraft safely. In 1975, after the conclusion of US involvement in the Vietnam war, it was transferred to the Air Force Reserve, where it served with the 711th Special Operations Squadron of the 919th Special Operations Wing. In 1980, the aircraft was upgraded from the original three-bladed propellers to the quieter four-bladed propellers and was eventually retired in late 1995. The retirement also marked an end to the Air Force Reserve Command flying the AC-130A. The aircraft now sits on display in the final Air Force Reserve Command configuration with grey paint, black markings, and the four-bladed Hamilton Sunstrand 54H60-91 props at the Air Force Armament Museum at Eglin Air Force Base, Florida, USA. A second aircraft, AF serial no. 56–0509, named the Ultimate End, was originally accepted as a C-130A by the Air Force on 28 February 1957, and modified to the AC-130A configuration on 27 July 1970. The aircraft participated in the Vietnam War and the rescue of the SS Mayaguez. Ultimate End demonstrated the durability of the C-130 after surviving hits in five places by 37 mm anti-aircraft artillery on 12 December 1970, extensive left wing leading edge damage on 12 April 1971 and a 57 mm round damaging the belly and injuring one crewman on 4 March 1972. "Ultimate End" was reassigned to the Air Force Reserve's 919th Special Operations Wing at Eglin AFB Auxiliary Field No.3 / Duke Field on 17 June 1975, where it continued in service until retired in the fall 1994 and transferred to Air Force Special Operations Command's Heritage Air Park at Hurlburt Field, Florida. While assigned to the 711th Special Operations Squadron, Ultimate End served in Operations JUST CAUSE in Panama, DESERT STORM in Kuwait and Iraq, and UPHOLD DEMOCRACY in Haiti. After 36 years and seven months of service, 24 years as a gunship, Ultimate End retired from active service on 1 October 1994. It made its last flight from Duke Field to Hurlburt Field on 20 October 1994. The Spectre Association dedicated "Ultimate End" (which served with the 16 SOS in Vietnam) on 4 May 1995. Lt Col Michael Byers, then 16 SOS commander, represented the active-duty gunship force and Clyde Gowdy of the Spectre Association represented all Spectre personnel past and present for the unveiling of a monument at the aircraft and the dedication as a whole. A third AC-130A, AF serial no. 54–1630, is on display in the Cold War Gallery at the National Museum of the United States Air Force at Wright-Patterson AFB, Ohio. Named Azrael for the angel of death in Islam who severs the soul from the body, this aircraft figured prominently in the closing hours of Operation Desert Storm. On 26 February 1991, Coalition ground forces were driving the Iraqi Army out of Kuwait. With an Air Force Reserve crew called to active duty, Azrael was sent to the Al Jahra highway (Highway 80) between Kuwait City and Basra, Iraq, to intercept the convoys of tanks, trucks, buses, and cars fleeing the battle. Facing SA-6 and SA-8 surface-to-air missiles and 37 mm and 57 mm radar-guided anti-aircraft artillery the crew attacked and destroyed or disabled most of the convoys. Azrael was also assigned to the 919th Special Operations Wing and retired to the museum in October 1995. Another AC-130A, AF serial no. 54–1626, the original prototype AC-130 named "Gunship II" is on display at the outdoor Air Park at the National Museum of the United States Air Force at Wright-Patterson AFB, Ohio. This aircraft served in Southeast Asia from 1967 to 1972, then served in JC-130A test configuration. It was transferred to the National Museum of the United States Air Force in 1976, and converted back to AC-130A configuration in the late 1990s. AC-130A serial no. 54–1623, c/n 3010, named "Ghost Rider" served in Southeast Asia and later conflicts until being retired in 1997 to Dobbins AFB, Georgia. Ghost Rider eventually was transferred and displayed at the Aviation Wing Museum at Marietta, Georgia. Specifications (AC-130) Notable appearances in media The AC-130 is a playable aircraft in many Call of Duty games, either as kill/scorestreaks in multiplayer or in missions in the campaigns.

Alternative algebra

In abstract algebra, an alternative algebra is an algebra in which multiplication need not be associative, only alternative. That is, one must have for all x and y in the algebra. Every associative algebra is obviously alternative, but so too are some strictly non-associative algebras such as the octonions. The associator Alternative algebras are so named because they are the algebras for which the associator is alternating. The associator is a trilinear map given by . By definition, a multilinear map is alternating if it vanishes whenever two of its arguments are equal. The left and right alternative identities for an algebra are equivalent to Both of these identities together imply that the associator is totally skew-symmetric. That is, for any permutation σ. It follows that for all x and y. This is equivalent to the flexible identity The associator of an alternative algebra is therefore alternating. Conversely, any algebra whose associator is alternating is clearly alternative. By symmetry, any algebra which satisfies any two of: left alternative identity: right alternative identity: flexible identity: is alternative and therefore satisfies all three identities. An alternating associator is always totally skew-symmetric. The converse holds so long as the characteristic of the base field is not 2. Examples Every associative algebra is alternative. The octonions form a non-associative alternative algebra, a normed division algebra of dimension 8 over the real numbers. More generally, any octonion algebra is alternative. Non-examples The sedenions and all higher Cayley–Dickson algebras lose alternativity. Properties Artin's theorem states that in an alternative algebra the subalgebra generated by any two elements is associative. Conversely, any algebra for which this is true is clearly alternative. It follows that expressions involving only two variables can be written unambiguously without parentheses in an alternative algebra. A generalization of Artin's theorem states that whenever three elements in an alternative algebra associate (i.e., ), the subalgebra generated by those elements is associative. A corollary of Artin's theorem is that alternative algebras are power-associative, that is, the subalgebra generated by a single element is associative. The converse need not hold: the sedenions are power-associative but not alternative. The Moufang identities hold in any alternative algebra. In a unital alternative algebra, multiplicative inverses are unique whenever they exist. Moreover, for any invertible element and all one has This is equivalent to saying the associator vanishes for all such and . If and are invertible then is also invertible with inverse . The set of all invertible elements is therefore closed under multiplication and forms a Moufang loop. This loop of units in an alternative ring or algebra is analogous to the group of units in an associative ring or algebra. Kleinfeld's theorem states that any simple non-associative alternative ring is a generalized octonion algebra over its center. The structure theory of alternative rings is presented in. Applications The projective plane over any alternative division ring is a Moufang plane. The close relationship of alternative algebras and composition algebras was given by Guy Roos in 2008: He shows (page 162) the relation for an algebra A with unit element e and an involutive anti-automorphism such that a + a* and aa* are on the line spanned by e for all a in A. Use the notation n(a) = aa*. Then if n is a non-singular mapping into the field of A, and A is alternative, then (A,n) is a composition algebra.

Arbitrage

In economics and finance, arbitrage (, ) is the practice of taking advantage of a difference in prices in two or more markets; striking a combination of matching deals to capitalize on the difference, the profit being the difference between the market prices at which the unit is traded. When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state; in simple terms, it is the possibility of a risk-free profit after transaction costs. For example, an arbitrage opportunity is present when there is the possibility to instantaneously buy something for a low price and sell it for a higher price. In principle and in academic use, an arbitrage is risk-free; in common use, as in statistical arbitrage, it may refer to expected profit, though losses may occur, and in practice, there are always risks in arbitrage, some minor (such as fluctuation of prices decreasing profit margins), some major (such as devaluation of a currency or derivative). In academic use, an arbitrage involves taking advantage of differences in price of a single asset or identical cash-flows; in common use, it is also used to refer to differences between similar assets (relative value or convergence trades), as in merger arbitrage. The term is mainly applied to trading in financial instruments, such as bonds, stocks, derivatives, commodities, and currencies. People who engage in arbitrage are called arbitrageurs (). Arbitrage has the effect of causing prices of the same or very similar assets in different markets to converge. Etymology "Arbitrage" is a French word and denotes a decision by an arbitrator or arbitration tribunal (in modern French, "" usually means referee or umpire). In the sense used here, it was first defined in 1704 by Mathieu de la Porte in his treatise "" as a consideration of different exchange rates to recognise the most profitable places of issuance and settlement for a bill of exchange (" [, in modern spelling] ".) Arbitrage-free If the market prices do not allow for profitable arbitrage, the prices are said to constitute an arbitrage equilibrium, or an arbitrage-free market. An arbitrage equilibrium is a precondition for a general economic equilibrium. The "no arbitrage" assumption is used in quantitative finance to calculate a unique risk neutral price for derivatives. Arbitrage-free pricing approach for bonds Arbitrage-free pricing for bonds is the method of valuing a coupon-bearing financial instrument by discounting its future cash flows by multiple discount rates. By doing so, a more accurate price can be obtained than if the price is calculated with a present-value pricing approach. Arbitrage-free pricing is used for bond valuation and to detect arbitrage opportunities for investors. For the purpose of valuing the price of a bond, its cash flows can each be thought of as packets of incremental cash flows with a large packet upon maturity, being the principal. Since the cash flows are dispersed throughout future periods, they must be discounted back to the present. In the present-value approach, the cash flows are discounted with one discount rate to find the price of the bond. In arbitrage-free pricing, multiple discount rates are used. The present-value approach assumes that the yield of the bond will stay the same until maturity. This is a simplified model because interest rates may fluctuate in the future, which in turn affects the yield on the bond. For this reason, the discount rate may be different for each of the cash flows. Each cash flow can be considered a zero-coupon instrument that pays one payment upon maturity. The discount rates used should be the rates of multiple zero-coupon bonds with maturity dates the same as each cash flow and similar risk as the instrument being valued. By using multiple discount rates, the arbitrage-free price is the sum of the discounted cash flows. Arbitrage-free price refers to the price at which no price arbitrage is possible. The idea of using multiple discount rates obtained from zero-coupon bonds and discounting a similar bond's cash flow to find its price is derived from the yield curve, which is a curve of the yields of the same bond with different maturities. This curve can be used to view trends in market expectations of how interest rates will move in the future. In arbitrage-free pricing of a bond, a yield curve of similar zero-coupon bonds with different maturities is created. If the curve were to be created with Treasury securities of different maturities, they would be stripped of their coupon payments through bootstrapping. This is to transform the bonds into zero-coupon bonds. The yield of these zero-coupon bonds would then be plotted on a diagram with time on the x-axis and yield on the y-axis. Since the yield curve displays market expectations on how yields and interest rates may move, the arbitrage-free pricing approach is more realistic than using only one discount rate. Investors can use this approach to value bonds and find mismatches in prices, resulting in an arbitrage opportunity. If a bond valued with the arbitrage-free pricing approach turns out to be priced higher in the market, an investor could have such an opportunity: Investor shorts the bond at price at time t1. Investor longs the zero-coupon bonds making up the related yield curve and strips and sells any coupon payments at t1. As t>t1, the price spread between the prices will decrease. At maturity, the prices will converge and be equal. Investor exits both the long and short positions, realizing a profit. If the outcome from the valuation were the reverse case, the opposite positions would be taken in the bonds. This arbitrage opportunity comes from the assumption that the prices of bonds with the same properties will converge upon maturity. This can be explained through market efficiency, which states that arbitrage opportunities will eventually be discovered and corrected. The prices of the bonds in t1 move closer together to finally become the same at tT. Conditions for arbitrage Arbitrage may take place when: the same asset does not trade at the same price on all markets ("the law of one price"). two assets with identical cash flows do not trade at the same price. an asset with a known price in the future does not today trade at its future price discounted at the risk-free interest rate (or the asset has significant costs of storage; so this condition holds true for something like grain but not for securities). Arbitrage is not simply the act of buying a product in one market and selling it in another for a higher price at some later time. The transactions must occur simultaneously to avoid exposure to market risk, or the risk that prices may change in one market before both transactions are complete. In practical terms, this is generally possible only with securities and financial products that can be traded electronically, and even then, when each leg of the trade is executed, the prices in the market may have moved. Missing one of the legs of the trade (and subsequently having to trade it soon after at a worse price) is called 'execution risk' or more specifically 'leg risk'. In the simplest example, any good sold in one market should sell for the same price in another. Traders may, for example, find that the price of wheat is lower in agricultural regions than in cities, purchase the good, and transport it to another region to sell at a higher price. This type of price arbitrage is the most common, but this simple example ignores the cost of transport, storage, risk, and other factors. "True" arbitrage requires that there is no market risk involved. Where securities are traded on more than one exchange, arbitrage occurs by simultaneously buying in one and selling on the other. See rational pricing, particularly § arbitrage mechanics, for further discussion. Mathematically it is defined as follows: where and denotes the portfolio value at time t. Price convergence Arbitrage has the effect of causing prices in different markets to converge. As a result of arbitrage, the currency exchange rates, the price of commodities, and the price of securities in different markets tend to converge. The speed at which they do so is a measure of market efficiency. Arbitrage tends to reduce price discrimination by encouraging people to buy an item where the price is low and resell it where the price is high (as long as the buyers are not prohibited from reselling and the transaction costs of buying, holding, and reselling are small, relative to the difference in prices in the different markets). Arbitrage moves different currencies toward purchasing power parity. Assume that a car purchased in the United States is cheaper than the same car in Canada. Canadians would buy their cars across the border to exploit the arbitrage condition. At the same time, Americans would buy US cars, transport them across the border, then sell them in Canada. Canadians would have to buy American dollars to buy the cars and Americans would have to sell the Canadian dollars they received in exchange. Both actions would increase demand for US dollars and supply of Canadian dollars. As a result, there would be an appreciation of the US currency. This would make US cars more expensive and Canadian cars less so until their prices were similar. On a larger scale, international arbitrage opportunities in commodities, goods, securities, and currencies tend to change exchange rates until the purchasing power is equal. In reality, most assets exhibit some difference between countries. These, transaction costs, taxes, and other costs provide an impediment to this kind of arbitrage. Similarly, arbitrage affects the difference in interest rates paid on government bonds issued by the various countries, given the expected depreciation in the currencies relative to each other (see interest rate parity). Risks Arbitrage transactions in modern securities markets involve fairly low day-to-day risks, but can face extremely high risk in rare situations, particularly financial crises, and can lead to bankruptcy. Formally, arbitrage transactions have negative skew – prices can get a small amount closer (but often no closer than 0), while they can get very far apart. The day-to-day risks are generally small because the transactions involve small differences in price, so an execution failure will generally cause a small loss (unless the trade is very big or the price moves rapidly). The rare case risks are extremely high because these small price differences are converted to large profits via leverage (borrowed money), and in the rare event of a large price move, this may yield a large loss. The main day-to-day risk is that part of the transaction fails; this is called execution risk. The main, rare risks are counterparty risk, and liquidity risk: that a counterparty to a large transaction or many transactions fails to pay, or that one is required to post margin and does not have the money to do so. In the academic literature, the idea that seemingly very low-risk arbitrage trades might not be fully exploited because of these risk factors and other considerations is often referred to as limits to arbitrage. Execution risk Generally, it is impossible to close two or three transactions at the same instant; therefore, there is the possibility that when one part of the deal is closed, a quick shift in prices makes it impossible to close the other at a profitable price. However, this is not necessarily the case. Many exchanges and inter-dealer brokers allow multi legged trades (e.g. basis block trades on LIFFE). Competition in the marketplace can also create risks during arbitrage transactions. As an example, if one was trying to profit from a price discrepancy between IBM on the NYSE and IBM on the London Stock Exchange, they may purchase a large number of shares on the NYSE and find that they cannot simultaneously sell on the LSE. This leaves the arbitrageur in an unhedged risk position. In the 1980s, risk arbitrage was common. In this form of speculation, one trades a security that is clearly undervalued or overvalued, when it is seen that the wrong valuation is about to be corrected. The standard example is the stock of a company, undervalued in the stock market, which is about to be the object of a takeover bid; the price of the takeover will more truly reflect the value of the company, giving a large profit to those who bought at the current price, if the merger goes through as predicted. Traditionally, arbitrage transactions in the securities markets involve high speed, high volume, and low risk. At some moment a price difference exists, and the problem is to execute two or three balancing transactions while the difference persists (that is, before the other arbitrageurs act). When the transaction involves a delay of weeks or months, as above, it may entail considerable risk if borrowed money is used to magnify the reward through leverage. One way of reducing this risk is through the illegal use of inside information, and risk arbitrage in leveraged buyouts was associated with some of the famous financial scandals of the 1980s, such as those involving Michael Milken and Ivan Boesky. Mismatch Another risk occurs if the items being bought and sold are not identical and the arbitrage is conducted under the assumption that the prices of the items are correlated or predictable; this is more narrowly referred to as a convergence trade. In the extreme case this is merger arbitrage, described below. In comparison to the classical quick arbitrage transaction, such an operation can produce disastrous losses. Counterparty risk As arbitrages generally involve future movements of cash, they are subject to counterparty risk: the risk that a counterparty fails to fulfill their side of a transaction. This is a serious problem if one has either a single trade or many related trades with a single counterparty, whose failure thus poses a threat, or in the event of a financial crisis when many counterparties fail. This hazard is serious because of the large quantities one must trade in order to make a profit on small price differences. For example, if one purchases many risky bonds, then hedges them with CDSes, profiting from the difference between the bond spread and the CDS premium, in a financial crisis, the bonds may default and the CDS writer/seller may fail, due to the stress of the crisis, causing the arbitrageur to face steep losses. Liquidity risk Arbitrage trades are necessarily synthetic, leveraged trades, as they involve a short position. If the assets used are not identical (so a price divergence makes the trade temporarily lose money), or the margin treatment is not identical, and the trader is accordingly required to post margin (faces a margin call), the trader may run out of capital (if they run out of cash and cannot borrow more) and be forced to sell these assets at a loss even though the trades may be expected to ultimately make money. In effect, arbitrage traders synthesize a put option on their ability to finance themselves. Prices may diverge during a financial crisis, often termed a "flight to quality"; these are precisely the times when it is hardest for leveraged investors to raise capital (due to overall capital constraints), and thus they will lack capital precisely when they need it most. Types Spatial arbitrage Also known as geographical arbitrage, this is the simplest form of arbitrage. In spatial arbitrage, an arbitrageur looks for price differences between geographically separate markets. For example, there may be a bond dealer in Virginia offering a bond at 100-12/23 and a dealer in Washington bidding 100-15/23 for the same bond. For whatever reason, the two dealers have not spotted the difference in the prices, but the arbitrageur does. The arbitrageur immediately buys the bond from the Virginia dealer and sells it to the Washington dealer. Merger arbitrage Also called risk arbitrage, merger arbitrage generally consists of buying/holding the stock of a company that is the target of a takeover while shorting the stock of the acquiring company. Usually, the market price of the target company is less than the price offered by the acquiring company. The spread between these two prices depends mainly on the probability and the timing of the takeover being completed as well as the prevailing level of interest rates. The bet in a merger arbitrage is that such a spread will eventually be zero, if and when the takeover is completed. The risk is that the deal "breaks" and the spread massively widens. Municipal bond arbitrage Also called municipal bond relative value arbitrage, municipal arbitrage, or just muni arb, this hedge fund strategy involves one of two approaches. The term "arbitrage" is also used in the context of the Income Tax Regulations governing the investment of proceeds of municipal bonds; these regulations, aimed at the issuers or beneficiaries of tax-exempt municipal bonds, are different and, instead, attempt to remove the issuer's ability to arbitrage between the low tax-exempt rate and a taxable investment rate. Generally, managers seek relative value opportunities by being both long and short municipal bonds with a duration-neutral book. The relative value trades may be between different issuers, different bonds issued by the same entity, or capital structure trades referencing the same asset (in the case of revenue bonds). Managers aim to capture the inefficiencies arising from the heavy participation of non-economic investors (i.e., high income "buy and hold" investors seeking tax-exempt income) as well as the "crossover buying" arising from corporations' or individuals' changing income tax situations (i.e., insurers switching their munis for corporates after a large loss as they can capture a higher after-tax yield by offsetting the taxable corporate income with underwriting losses). There are additional inefficiencies arising from the highly fragmented nature of the municipal bond market which has two million outstanding issues and 50,000 issuers, in contrast to the Treasury market which has 400 issues and a single issuer. Second, managers construct leveraged portfolios of AAA- or AA-rated tax-exempt municipal bonds with the duration risk hedged by shorting the appropriate ratio of taxable corporate bonds. These corporate equivalents are typically interest rate swaps referencing Libor or SIFMA. The arbitrage manifests itself in the form of a relatively cheap longer maturity municipal bond, which is a municipal bond that yields significantly more than 65% of a corresponding taxable corporate bond. The steeper slope of the municipal yield curve allows participants to collect more after-tax income from the municipal bond portfolio than is spent on the interest rate swap; the carry is greater than the hedge expense. Positive, tax-free carry from muni arb can reach into the double digits. The bet in this municipal bond arbitrage is that, over a longer period of time, two similar instruments—municipal bonds and interest rate swaps—will correlate with each other; they are both very high quality credits, have the same maturity and are denominated in the same currency. Credit risk and duration risk are largely eliminated in this strategy. However, basis risk arises from use of an imperfect hedge, which results in significant, but range-bound principal volatility. The end goal is to limit this principal volatility, eliminating its relevance over time as the high, consistent, tax-free cash flow accumulates. Since the inefficiency is related to government tax policy, and hence is structural in nature, it has not been arbitraged away. However, many municipal bonds are callable, and this adds substantial risks to the strategy. Convertible bond arbitrage A convertible bond is a bond that an investor can return to the issuing company in exchange for a predetermined number of shares in the company. A convertible bond can be thought of as a corporate bond with a stock call option attached to it. The price of a convertible bond is sensitive to three major factors: interest rate. When rates move higher, the bond part of a convertible bond tends to move lower, but the call option part of a convertible bond moves higher (and the aggregate tends to move lower). stock price. When the price of the stock the bond is convertible into moves higher, the price of the bond tends to rise. credit spread. If the creditworthiness of the issuer deteriorates (e.g. rating downgrade) and its credit spread widens, the bond price tends to move lower, but, in many cases, the call option part of the convertible bond moves higher (since credit spread correlates with volatility). Given the complexity of the calculations involved and the convoluted structure that a convertible bond can have, an arbitrageur often relies on sophisticated quantitative models in order to identify bonds that are trading cheap versus their theoretical value. Convertible arbitrage consists of buying a convertible bond and hedging two of the three factors in order to gain exposure to the third factor at a very attractive price. For instance an arbitrageur would first buy a convertible bond, then sell fixed income securities or interest rate futures (to hedge the interest rate exposure) and buy some credit protection (to hedge the risk of credit deterioration). Eventually what he or she would be left with is something similar to a call option on the underlying stock, acquired at a very low price. He or she could then make money either selling some of the more expensive options that are openly traded in the market or delta hedging his or her exposure to the underlying shares. Depository receipts A depositary receipt is a security that is offered as a "tracking stock" on another foreign market. For instance, a Chinese company wishing to raise more money may issue a depository receipt on the New York Stock Exchange, as the amount of capital on the local exchanges is limited. These securities, known as ADRs (American depositary receipt) or GDRs (global depository receipt) depending on where they are issued, are typically considered "foreign" and therefore trade at a lower value when first released. Many ADR's are exchangeable into the original security (known as fungibility) and actually have the same value. In this case, there is a spread between the perceived value and real value, which can be extracted. Other ADR's that are not exchangeable often have much larger spreads. Since the ADR is trading at a value lower than what it is worth, one can purchase the ADR and expect to make money as its value converges on the original. However, there is a chance that the original stock will fall in value too, so by shorting it one can hedge that risk. Cross-border arbitrage Cross-border arbitrage exploits different prices of the same stock in different countries: Example: Apple is trading on NASDAQ at US$108.84. The stock is also traded on the German electronic exchange, XETRA. If 1 euro costs US$1.11, a cross-border trader could enter a buy order on the XETRA at €98.03 per Apple share and a sell order at €98.07 per share. Some brokers in Germany do not offer access to the U.S. exchanges. Hence if a German retail investor wants to buy Apple stock, he needs to buy it on the XETRA. The cross-border trader would sell the Apple shares on XETRA to the investor and buy the shares in the same second on NASDAQ. Afterwards, the cross-border trader would need to transfer the shares bought on NASDAQ to the German XETRA exchange, where he is obliged to deliver the stock. In most cases, the quotation on the local exchanges is done electronically by high-frequency traders, taking into consideration the home price of the stock and the exchange rate. This kind of high-frequency trading benefits the public, as it reduces the cost to the German investor and enables them to buy U.S. shares. Dual-listed companies A dual-listed company (DLC) structure involves two companies incorporated in different countries contractually agreeing to operate their businesses as if they were a single enterprise, while retaining their separate legal identity and existing stock exchange listings. In integrated and efficient financial markets, stock prices of the twin pair should move in lockstep. In practice, DLC share prices exhibit large deviations from theoretical parity. Arbitrage positions in DLCs can be set up by obtaining a long position in the relatively underpriced part of the DLC and a short position in the relatively overpriced part. Such arbitrage strategies start paying off as soon as the relative prices of the two DLC stocks converge toward theoretical parity. However, since there is no identifiable date at which DLC prices will converge, arbitrage positions sometimes have to be kept open for considerable periods of time. In the meantime, the price gap might widen. In these situations, arbitrageurs may receive margin calls, after which they would most likely be forced to liquidate part of the position at a highly unfavorable moment and suffer a loss. Arbitrage in DLCs may be profitable, but is also very risky. A good illustration of the risk of DLC arbitrage is the position in Royal Dutch Shell—which had a DLC structure until 2005—by the hedge fund Long-Term Capital Management (LTCM, see also the discussion below). Lowenstein (2000) describes that LTCM established an arbitrage position in Royal Dutch Shell in the summer of 1997, when Royal Dutch traded at an 8 to 10 percent premium. In total, $2.3 billion was invested, half of which was long in Shell and the other half was short in Royal Dutch (Lowenstein, p. 99). In the autumn of 1998, large defaults on Russian debt created significant losses for the hedge fund and LTCM had to unwind several positions. Lowenstein reports that the premium of Royal Dutch had increased to about 22 percent and LTCM had to close the position and incur a loss. According to Lowenstein (p. 234), LTCM lost $286 million in equity pairs trading and more than half of this loss is accounted for by the Royal Dutch Shell trade. (See further under Limits to arbitrage.) Private to public equities The market prices for privately held companies are typically viewed from a return on investment perspective (such as 25%), whilst publicly held and or exchange listed companies trade on a Price to earnings ratio (P/E) (such as a P/E of 10, which equates to a 10% ROI). Thus, if a publicly traded company specialises in the acquisition of privately held companies, from a per-share perspective there is a gain with every acquisition that falls within these guidelines. E.g., Berkshire Hathaway. Private to public equities arbitrage is a term that can arguably be applied to investment banking in general. Private markets to public markets differences may also help explain the overnight windfall gains enjoyed by principals of companies that just did an initial public offering (IPO). Regulatory arbitrage Regulatory arbitrage "is an avoidance strategy of regulation that is exercised as a result of a regulatory inconsistency". In other words, where a regulated institution takes advantage of the difference between its real (or economic) risk and the regulatory position. For example, if a bank, operating under the Basel I accord, has to hold 8% capital against default risk, but the real risk of default is lower, it is profitable to securitise the loan, removing the low-risk loan from its portfolio. On the other hand, if the real risk is higher than the regulatory risk then it is profitable to make that loan and hold on to it, provided it is priced appropriately. Regulatory arbitrage can result in parts of entire businesses being unregulated as a result of the arbitrage. This process can increase the overall riskiness of institutions under a risk insensitive regulatory regime, as described by Alan Greenspan in his October 1998 speech on The Role of Capital in Optimal Banking Supervision and Regulation. The term "Regulatory Arbitrage" was used for the first time in 2005 when it was applied by Scott V. Simpson, a partner at law firm Skadden, Arps, to refer to a new defence tactic in hostile mergers and acquisitions where differing takeover regimes in deals involving multi-jurisdictions are exploited to the advantage of a target company under threat. In economics, regulatory arbitrage (sometimes, tax arbitrage) may refer to situations when a company can choose a nominal place of business with a regulatory, legal or tax regime with lower costs. This can occur particularly where the business transaction has no obvious physical location. In the case of many financial products, it may be unclear "where" the transaction occurs. Regulatory arbitrage can include restructuring a bank by outsourcing services such as IT. The outsourcing company takes over the installations, buying out the bank's assets and charges a periodic service fee back to the bank. This frees up cashflow usable for new lending by the bank. The bank will have higher IT costs, but counts on the multiplier effect of money creation and the interest rate spread to make it a profitable exercise. Example: Suppose the bank sells its IT installations for US$40 million. With a reserve ratio of 10%, the bank can create US$400 million in additional loans (there is a time lag, and the bank has to expect to recover the loaned money back into its books). The bank can often lend (and securitize the loan) to the IT services company to cover the acquisition cost of the IT installations. This can be at preferential rates, as the sole client using the IT installation is the bank. If the bank can generate 5% interest margin on the 400 million of new loans, the bank will increase interest revenues by 20 million. The IT services company is free to leverage their balance sheet as aggressively as they and their banker agree to. This is the reason behind the trend towards outsourcing in the financial sector. Without this money creation benefit, it is actually more expensive to outsource the IT operations as the outsourcing adds a layer of management and increases overhead. According to PBS Frontline's 2012 four-part documentary, "Money, Power, and Wall Street," regulatory arbitrage, along with asymmetric bank lobbying in Washington and abroad, allowed investment banks in the pre- and post-2008 period to continue to skirt laws and engage in the risky proprietary trading of opaque derivatives, swaps, and other credit-based instruments invented to circumvent legal restrictions at the expense of clients, government, and publics. Due to the Affordable Care Act's expansion of Medicaid coverage, one form of Regulatory Arbitrage can now be found when businesses engage in “Medicaid Migration”, a maneuver by which qualifying employees who would typically be enrolled in company health plans elect to enroll in Medicaid instead. These programs that have similar characteristics as insurance products to the employee, but have radically different cost structures, resulting in significant expense reductions for employers. Telecom arbitrage Telecom arbitrage companies allow phone users to make international calls for free through certain access numbers. Such services are offered in the United Kingdom; the telecommunication arbitrage companies get paid an interconnect charge by the UK mobile networks and then buy international routes at a lower cost. The calls are seen as free by the UK contract mobile phone customers since they are using up their allocated monthly minutes rather than paying for additional calls. Such services were previously offered in the United States by companies such as FuturePhone.com. These services would operate in rural telephone exchanges, primarily in small towns in the state of Iowa. In these areas, the local telephone carriers are allowed to charge a high "termination fee" to the caller's carrier in order to fund the cost of providing service to the small and sparsely populated areas that they serve. However, FuturePhone (as well as other similar services) ceased operations upon legal challenges from AT&T and other service providers. Statistical arbitrage Statistical arbitrage is an imbalance in expected nominal values. A casino has a statistical arbitrage in every game of chance that it offers, referred to as the house advantage, house edge, vigorish, or house vigorish. The fall of Long-Term Capital Management Long-Term Capital Management (LTCM) lost 4.6 billion U.S. dollars in fixed income arbitrage in September 1998. LTCM had attempted to make money on the price difference between different bonds. For example, it would sell U.S. Treasury securities and buy Italian bond futures. The concept was that because Italian bond futures had a less liquid market, in the short term Italian bond futures would have a higher return than U.S. bonds, but in the long term, the prices would converge. Because the difference was small, a large amount of money had to be borrowed to make the buying and selling profitable. The downfall in this system began on August 17, 1998, when Russia defaulted on its ruble debt and domestic dollar debt. Because global markets were already nervous due to the 1997 Asian financial crisis, investors began selling non-U.S. treasury debt and buying U.S. treasuries, which were considered a safe investment. As a result, the price on US treasuries began to increase and the return began decreasing because there were many buyers, and the return (yield) on other bonds began to increase because there were many sellers (i.e. the price of those bonds fell). This caused the difference between the prices of U.S. treasuries and other bonds to increase, rather than to decrease as LTCM was expecting. Eventually this caused LTCM to fold, and their creditors had to arrange a bail-out. More controversially, officials of the Federal Reserve assisted in the negotiations that led to this bail-out, on the grounds that so many companies and deals were intertwined with LTCM that if LTCM actually failed, they would as well, causing a collapse in confidence in the economic system. Thus LTCM failed as a fixed income arbitrage fund, although it is unclear what sort of profit was realized by the banks that bailed LTCM out.

ACF Fiorentina

ACF Fiorentina, commonly referred to as Fiorentina (), is an Italian professional football club based in Florence, Tuscany, Italy. The original team was founded by a merger in August 1926, while the actual club was refounded in August 2002 following bankruptcy. Fiorentina have played at the top level of Italian football for the majority of their existence; only four clubs have played in more Serie A seasons. Fiorentina has won two Italian Championships, in 1955–56 and again in 1968–69, as well as six Coppa Italia trophies and one Supercoppa Italiana. On the European stage, Fiorentina won the UEFA Cup Winners' Cup in 1960–61 and lost the final one year later. They finished runners-up in the 1956–57 European Cup, losing against Real Madrid, and also came close to winning the 1989–90 UEFA Cup, finishing as runners-up against Juventus after losing the first leg in Turin and drawing in the second one in Avellino. Fiorentina is one of the fifteen European teams that played the finals in all three major continental competitions: the Champions League (1956–1957, the first Italian team to reach the final in the top continental competition), the UEFA Cup Winners (1960–1961 and 1961–1962) and the UEFA Cup (1989–1990). Since 1931, the club have played at the Stadio Artemio Franchi, which currently has a capacity of 43,147. The stadium has used several names over the years and has undergone several renovations. Fiorentina are known widely by the nickname Viola, a reference to their distinctive purple colours. History Foundation to World War II Associazione Calcio Fiorentina was founded in the autumn of 1926 by local noble and National Fascist Party member Luigi Ridolfi, who initiated the merger of two older Florentine clubs, CS Firenze and PG Libertas. The aim of the merger was to give Florence a strong club to rival those of the more dominant Italian Football Championship sides of the time from Northwest Italy. Also influential was the cultural revival and rediscovery of Calcio Fiorentino, an ancestor of modern football that was played by members of the Medici family. After a rough start and three seasons in lower leagues, Fiorentina reached the Serie A in 1931. That same year saw the opening of the new stadium, originally named after Giovanni Berta, a prominent fascist, but now known as Stadio Artemio Franchi. At the time, the stadium was a masterpiece of engineering, and its inauguration was monumental. To be able to compete with the best teams in Italy, Fiorentina strengthened their team with some new players, notably the Uruguayan Pedro Petrone, nicknamed el Artillero. Despite enjoying a good season and finishing in fourth place, Fiorentina were relegated the following year, although they would return quickly to Serie A. In 1941, they won their first Coppa Italia, but the team were unable to build on their success during the 1940s due to World War II and other troubles. First scudetto and '50–'60s In 1950, Fiorentina started to achieve consistent top-five finishes in the domestic league. The team consisted of great players such as well-known goalkeeper Giuliano Sarti, Sergio Cervato, Francesco Rosella, Guido Gratton, Giuseppe Chiappella and Aldo Scaramucci but above all, the attacking duo of Brazilian Julinho and Argentinian Miguel Montuori. This team won Fiorentina's first scudetto (Italian championship) in 1955–56, 12 points ahead of second-place Milan. Milan beat Fiorentina to top spot the following year, but more significantly Fiorentina became the first Italian team to play in a European Cup final, when a disputed penalty led to a 2–0 defeat at the hands of Alfredo Di Stéfano's Real Madrid. Fiorentina were runners-up again in the three subsequent seasons. In the 1960–61 season, the club won the Coppa Italia again and was also successful in Europe, winning the first Cup Winners' Cup against Scottish side Rangers. After several years of runner-up finishes, Fiorentina dropped away slightly in the 1960s, bouncing from fourth to sixth place, although the club won the Coppa Italia and the Mitropa Cup in 1966. Second scudetto and '70s While the 1960s did result in some trophies and good Serie A finishes for Fiorentina, nobody believed that the club could challenge for the title. The 1968–69 season started with Milan as frontrunners, but on matchday 7, they lost to Bologna and were overtaken by Gigi Riva's Cagliari. Fiorentina, after an unimpressive start, then moved to the top of the Serie A, but the first half of their season finished with a 2–2 draw against Varese, leaving Cagliari as outright league leader. The second half of the season was a three-way battle between the three contending teams, Milan, Cagliari and Fiorentina. Milan fell away, instead focusing their efforts on the European Cup, and it seemed that Cagliari would retain top spot. After Cagliari lost against Juventus, however, Fiorentina took over at the top. The team then won all of their remaining matches, beating rivals Juve in Turin on the penultimate matchday to seal their second, and last, national title. In the European Cup competition the following year, Fiorentina had some good results, including a win in the Soviet Union against Dynamo Kyiv, but they were eventually knocked out in the quarter-finals after a 3–0 defeat in Glasgow to Celtic. Viola players began the 1970s decade with Scudetto sewed on their breast, but the period was not especially fruitful for the team. After a fifth-place finish in 1971, they finished in mid-table almost every year, even flirting with relegation in 1972 and 1978. The Viola did win the Anglo-Italian League Cup in 1974 and won the Coppa Italia again in 1975. The team consisted of young talents like Vincenzo Guerini and Moreno Roggi, who had the misfortune to suffer bad injuries, and above all Giancarlo Antognoni, who would later become an idol to Fiorentina's fans. The young average age of the players led to the team being called Fiorentina Ye-Ye. Pontello era In 1980, Fiorentina was bought by Flavio Pontello, who came from a rich house-building family. He quickly changed the team's anthem and logo, leading to some complaints by the fans, but he started to bring in high-quality players such as Francesco Graziani and Eraldo Pecci from Torino; Daniel Bertoni from Sevilla; Daniele Massaro from Monza; and a young Pietro Vierchowod from Como. The team was built around Giancarlo Antognoni, and in 1982, Fiorentina were involved in an exciting duel with rivals Juventus. After a bad injury to Antognoni, the league title was decided on the final day of the season when Fiorentina were denied a goal against Cagliari and were unable to win. Juventus won the title with a disputed penalty and the rivalry between the two teams erupted. The following years were strange for Fiorentina, who vacillated between high finishes and relegation battles. Fiorentina also bought two interesting players, El Puntero Ramón Díaz and, most significantly, the young Roberto Baggio. In 1990, Fiorentina fought to avoid relegation right up until the final day of the season, but did reach the UEFA Cup final, where they again faced Juventus. The Turin team won the trophy, but Fiorentina's tifosi once again had real cause for complaint: the second leg of the final was played in Avellino (Fiorentina's home ground was suspended), a city with many Juventus fans, and emerging star Roberto Baggio was sold to the rival team on the day of the final. Pontello, suffering from economic difficulties, was selling all the players and was forced to leave the club after serious riots in Florence's streets. The club was then acquired by the famous filmmaker Mario Cecchi Gori. Cecchi Gori era: from Champions League to bankruptcy The first season under Cecchi Gori's ownership was one of stabilisation, after which the new chairman started to sign some good players like Brian Laudrup, Stefan Effenberg, Francesco Baiano and, most importantly, Gabriel Batistuta, who became an iconic player for the team during the 1990s. In 1993, however, Cecchi Gori died and was succeeded as chairman by his son, Vittorio. Despite a good start to the season, Cecchi Gori fired the coach, Luigi Radice, after a defeat against Atalanta, and replaced him with Aldo Agroppi. The results were dreadful: Fiorentina fell into the bottom half of the standings and were relegated on the last day of the season. Claudio Ranieri was brought in as coach for the 1993–94 season, and that year, Fiorentina dominated Serie B, Italy's second division. Upon their return to Serie A, Ranieri put together a good team centred around new top scorer Batistuta, signing the young talent Rui Costa from Benfica and the new world champion Brazilian defender Márcio Santos. The former became an idol to Fiorentina fans, while the second disappointed and was sold after only a season. The Viola finished the season in tenth place. The following season, Cecchi Gori bought other important players, namely Swedish midfielder Stefan Schwarz. The club again proved its mettle in cup competitions, winning the Coppa Italia against Atalanta and finishing joint-third in Serie A. In the summer, Fiorentina became the first non-national champions to win the Supercoppa Italiana, defeating Milan 2–1 at the San Siro. Fiorentina's 1996–97 season was disappointing in the league, but they did reach the Cup Winners' Cup semi-final by beating Gloria Bistrița, Sparta Prague and Benfica. The team lost the semi-final to the eventual winner of the competition, Barcelona (away 1–1; home 0–2). The season's main signings were Luís Oliveira and Andrei Kanchelskis, the latter of whom suffered from many injuries. At the end of the season, Ranieri left Fiorentina for Valencia in Spain, with Cecchi Gori appointing Alberto Malesani as his replacement. Fiorentina played well but struggled against smaller teams, although they did manage to qualify for the UEFA Cup. Malesani left Fiorentina after only a season and was succeeded by Giovanni Trapattoni. With Trapattoni's expert guidance and Batistuta's goals, Fiorentina challenged for the title in 1998–99 but finished the season in third, earning them qualification for the Champions League. The following year was disappointing in Serie A, but Viola played some historical matches in the Champions League, beating Arsenal 1–0 at the old Wembley Stadium and Manchester United 2–0 in Florence. They were ultimately eliminated in the second group stage. At the end of the season, Trapattoni left the club and was replaced by Turkish coach Fatih Terim. More significantly, however, Batistuta was sold to Roma, who eventually won the title the following year. Fiorentina played well in 2000–01 and stayed in the top half of Serie A, despite the resignation of Terim and the arrival of Roberto Mancini. They also won the Coppa Italia for the sixth and last time. The year 2001 heralded major changes for Fiorentina, as the terrible state of the club's finances was revealed: they were unable to pay wages and had debts of around US$50 million. The club's owner, Vittorio Cecchi Gori, was able to raise some more money, but this soon proved to be insufficient to sustain the club. Fiorentina were relegated at the end of the 2001–02 season and went into judicially-controlled administration in June 2002. This form of bankruptcy (sports companies cannot exactly fail in this way in Italy, but they can suffer a similar procedure) meant that the club was refused a place in Serie B for the 2002–03 season, and as a result effectively ceased to exist. Della Valle era: from fourth tier to Europe (2000s and 2010s) The club was promptly re-established in August 2002 as Associazione Calcio Fiorentina e Florentia Viola with shoe and leather entrepreneur Diego Della Valle as new owner and the club was admitted into Serie C2, the fourth tier of Italian football. The only player to remain at the club in its new incarnation was Angelo Di Livio, whose commitment to the club's cause further endeared him to the fans. Helped by Di Livio and 30-goal striker Christian Riganò, the club won its Serie C2 group with considerable ease, which would normally have led to a promotion to Serie C1. Due to the bizarre Caso Catania (Catania Case), however, the club skipped Serie C1 and was admitted into Serie B, something that was only made possible by the Italian Football Federation (FIGC)'s decision to resolve the Catania situation by increasing the number of teams in Serie B from 20 to 24 and promoting Fiorentina for "sports merits." In the 2003 off-season, the club also bought back the right to use the Fiorentina name and the famous shirt design, and re-incorporated itself as ACF Fiorentina. The club finished the 2003–04 season in sixth place and won the playoff against Perugia to return to top-flight football. In their first season back in Serie A, however, the club struggled to avoid relegation, only securing survival on the last day of the season on head-to-head record against Bologna and Parma. In 2005, Della Valle decided to appoint Pantaleo Corvino as new sports director, followed by the appointment of Cesare Prandelli as head coach in the following season. The club made several signings during the summer transfer market, most notably Luca Toni and Sébastien Frey. This drastic move earned them a fourth-place finish with 74 points and a Champions League qualifying round ticket. Toni scored 31 goals in 38 appearances, the first player to pass the 30-goal mark since Antonio Valentin Angelillo in the 1958–59 season, for which he was awarded the European Golden Boot. On 14 July 2006, however, Fiorentina were relegated to Serie B due to their involvement in the 2006 Serie A match fixing scandal and given a 12-point penalty. The team was reinstated to the Serie A on appeal, but with a 19-point penalty for the 2006–07 season. The team's 2006–07 Champions League place was also revoked. After the start of the season, Fiorentina's penalisation was reduced from 19 points to 15 on appeal to the Italian courts. In spite of this penalty, they managed to secure a place in the UEFA Cup. Despite Toni's departure to Bayern Munich, Fiorentina had a strong start to the 2007–08 season and were tipped by Italian national team head coach Marcello Lippi, among others, as a surprise challenger for the Scudetto, and although this form tailed off towards the middle of the season, the Viola managed to qualify for the Champions League. In Europe, the club reached the semi-final of the UEFA Cup, where they were ultimately defeated by Rangers on penalties. The 2008–09 season continued this success, a fourth-place finish assuring Fiorentina's spot in 2010's Champions League playoffs. Their European campaign was also similar to that of the previous run, relegated to the 2008–09 UEFA Cup and were eliminated by Ajax in the end. In the 2009–10 season, Fiorentina started their domestic campaign strongly before steadily losing momentum and slipped to mid-table positions at the latter half of the season. In Europe, the team proved to be a surprise dark horse: after losing their first away fixture against Lyon, they staged a comeback with a five-match streak by winning all their remaining matches (including defeating Liverpool home and away). The Viola qualified as group champions, but eventually succumbed to Bayern Munich due to the away goals rule. This was controversial due to a mistaken refereeing decision by Tom Henning Øvrebø, who allowed a clearly offside goal for Bayern in the first leg. Bayern eventually finished the tournament as runners-up, making a deep run all the way to the final. The incident called into attention the possible implementation of video replays in football. Despite a good European run and reaching the semi-finals in the Coppa Italia, Fiorentina failed to qualify for Europe. During this period, on 24 September 2009, Andrea Della Valle resigned from his position as chairman of Fiorentina, and announced all duties would be temporarily transferred to Mario Cognini, Fiorentina's vice-president until a permanent position could be filled. In June 2010, the Viola bid farewell to long-time manager Cesare Prandelli, by then the longest-serving coach in the team's history, who was departing to coach the Italian national team. Catania manager Siniša Mihajlović was appointed to replace him. The club spent much of the early 2010–11 season in last place, but their form improved and Fiorentina ultimately finished ninth. Following a 1–0 defeat to Chievo in November 2011, Mihajlović was sacked and replaced by Delio Rossi. After a brief period of improvements, the Viola were again fighting relegation, prompting the sacking of Sporting Director Pantaleo Corvino in early 2012 following a 0–5 home defeat to Juventus. Their bid for survival was kept alive by a number of upset victories away from home, notably at Roma and Milan. During a home game against Novara, trailing 0–2 within half an hour, manager Rossi decided to substitute midfielder Adem Ljajić early. Ljajić sarcastically applauded him in frustration, whereupon Rossi retaliated by physical assaulting his player, an action that ultimately prompted his termination by the club. His replacement, caretaker manager Vincenzo Guerini, then guided the team away from the relegation zone to a 13th-place finish to end the turbulent year. To engineer a resurrection of the club after the disappointing season, the Della Valle family invested heavily in the middle of 2012, buying 17 new players and appointing Vincenzo Montella as head coach. The team began the season well, finishing the calendar year in joint third place and eventually finishing the 2012–13 season in fourth, enough for a position in the 2013–14 Europa League. The club lost fan favourite Stevan Jovetić during the middle of 2013, selling him to English Premier League club Manchester City for a €30 million transfer fee. They also sold Adem Ljajić to Roma and Alessio Cerci to Torino, using the funds to bring in Mario Gómez, Josip Iličić and Ante Rebić, among others. During the season, Fiorentina topped their Europa League group, moving on to the round of 32 to face Danish side Esbjerg fB, which Fiorentina defeated 4–2 on aggregate. In the following round of 16, however, they then lost to Italian rivals Juventus 2–1 on aggregate, ousting Fiorentina from the competition. At the end of the season, the team finished fourth again in the league, and also finishing the year as Coppa Italia runners-up after losing 3–1 to Napoli in the final. In 2014–15, during the 2015 winter transfer window, the team club sold star winger Juan Cuadrado to Chelsea for €30 million but were able to secure the loan of Mohamed Salah in exchange, who was a revelation in the second half of the season. Their 2014–15 Europa League campaign saw them progress to the semi-finals, where they were knocked-out by Spanish side Sevilla, the eventual champions. In the 2014–15 domestic season, Fiorentina once again finished fourth, thus qualifying for the 2015–16 Europa League. In June 2015, Vincenzo Montella was sacked as manager after the club grew impatient with the coaches inability to prove his commitment to the club, and was replaced by Paulo Sousa, who lasted until June 2017 and the appointment of Stefano Pioli. Club captain Davide Astori died suddenly at the age of 31 in March 2018. Astori had suffered a cardiac arrest while in a hotel room before an away game. The club subsequently retired Astori's kit number, 13. Fiorentina suffered during the 2018–19 Serie A campaign and ended the season on a 14 match winless streak, finishing in 16th place with only 41 points, 3 points from the relegation zone. On 9 April 2019, Pioli resigned as manager and was replaced by Montella Commisso era On 6 June 2019, the club was sold to Italian-American billionaire Rocco Commisso for around 160 million euros. The sale marked the end of the Della Valle family's seventeen-year association with the club. Vincenzo Montella was confirmed as coach for the first season of the new era despite the team's poor end to the previous campaign, which saw them finish only three points clear of the relegation zone. Fiorentina continued their struggles from the previous year, spending the majority of the season in lower midtable. Montella was sacked on 21 December after a 7 match winless run which left the club in 15th place, and was replaced by Giuseppe Iachini. In November 2020 Cesare Prandelli returned to Fiorentina, replacing Giuseppe Iachini as coach.

Below is a chronological list from the club's foundation in 1926 to the present day. Colours and badge Badge The official emblem of the city of Florence, a red fleur-de-lis on a white field, has been pivotal in the all-round symbolism of the club. Over the course of the club's history, they have had several badge changes, all of which incorporated Florence's fleur-de-lis in some way. The first one was nothing more than the city's coat of arms, a white shield with the red fleur-de-lis inside. It was soon changed to a very stylised fleur-de-lis, always red, and sometimes even without the white field. The most common symbol, adopted for about 20 years, had been a white lozenge with the flower inside. During the season they were Italian champions, the lozenge disappeared and the flower was overlapped with the scudetto. The logo introduced by owner Flavio Pontello in 1980 was particularly distinct, consisting of one-half of the city of Florence's emblem and one-half of the letter "F", for Fiorentina. People disliked it when it was introduced, believing it was a commercial decision and, above all, because the symbol bore more of a resemblance to a halberd than a fleur-de-lis. Today's logo is a kite shaped double lozenge bordered in gold. The outer lozenge has a purple background with the letters "AC" in white and the letter "F" in red, standing for the club's name. The inner lozenge is white with a gold border and the red fleur-de-lis of Florence. This logo had been in use from 1992 to 2002, but after the financial crisis and resurrection of the club the new one couldn't use the same logo. Florence's comune instead granted Florentia Viola use of the stylised coat of arms used in other city documents. Diego Della Valle acquired the current logo the following year in a judicial auction for a fee of €2.5 million, making it the most expensive logo in Italian football. Kit and colours When Fiorentina was founded in 1926, the players wore red and white halved shirts derived from the colour of the city emblem. The more well-known and highly distinctive purple kit was adopted in 1928 and has been used ever since, giving rise to the nickname La Viola ("The Purple (team)"). Tradition has it that Fiorentina got their purple kit by mistake after an accident washing the old red and white coloured kits in the river. The away kit has always been predominantly white, sometimes with purple and red elements, sometimes all-white. The shorts had been purple when the home kit was with white shorts. Fiorentina's third kit was first worn in the 1995–96 season and it was all-red with purple borders and two lilies on the shoulders. The red shirt has been the most worn 3rd shirt by Fiorentina, although they also wore rare yellow shirts ('97–'98, '99–'00 and '10–'11) and a sterling version, mostly in the Coppa Italia, in 2000–01. For the 2017–18 season and the first time in its history, the club used five kits during the season, composing of one home kit (all-purple) and four away kits, each one representing one historic quartiere of the city of Florence: all-blue (Santa Croce), all-white (Santo Spirito), all-green (San Giovanni) and all-red (Santa Maria Novella). Anthem "Canzone Viola" (Purple Song) is the title of the Fiorentina'a song, nowadays better known as "Oh Fiorentina". It is the oldest official football anthem in Italy and one of the oldest in the world. Dated 1930 and born only four years after the creation of the club, the song was written by a 12-year-old child, Enzo Marcacci, and musically arranged by maestro Marco Vinicio. It was published for the first time by the publisher Marcello Manni, who later became the owner of the rights. It soon achieved notoriety thanks to the printed media and the Ordine del Marzocco, a sort of original viola-club, which printed the lyrics of the song and distributed it to a home match on November 22, 1931. The song was recorded by Narciso Parigi in 1959 and again in 1965; the latter version replaced the original edition as the Fiorentina anthem. Subsequently, Narciso Parigi himself acquired the ownership of the rights, which he donated in 2002 to the supporter club Collettivo Autonomo Viola.

Fiorentina S.p.A. was unable to register for 2002–03 Serie B due to financial difficulties, and then the sports title was transferred to a new company thanks to Article 52 of N.O.I.F., while the old company was liquidated. At that time the club was heavily relying on windfall profit from selling players, especially in pure player swap or cash plus player swap that potentially increased the cost by the increase in amortisation of player contracts (an intangible assets). For example, Marco Rossi joined Fiorentina for 17 billion lire in 2000, but at the same time Lorenzo Collacchioni moved to Salernitana for 1 billion lire, meaning the club had a player profit of 997 million lire and extra 1 billion lire to be amortised in 5-years. In 1999, Emiliano Bigica also swapped with Giuseppe Taglialatela, which the latter was valued for 10 billion lire. The operating income (excluding windfall profit from players trading) of 2000–01 season was minus 113,271,475,933 Italian lire (minus €58,499,835). It was only boosted by the sales of Francesco Toldo and Rui Costa in June 2001 (a profit of 134.883 billion lire; €69.661 million). However, it was alleged they were to transfer to Parma for a reported 140 million lire. The two players eventually joined Inter Milan and A.C. Milan in 2001–02 financial year instead, for undisclosed fees. Failing to have financial support from the owner Vittorio Cecchi Gori, the club was forced to windup due to its huge imbalance in operating income. Since re-established in 2002, ACF Fiorentina S.p.A. are yet to self-sustain to keep the team in top division as well as in European competitions. In the 2005 financial year, which cover the first Serie A season, the club made a net loss of €9,159,356, followed by a net loss of €19,519,789. In 2006 (2005–06 Serie A and 2006–07 Serie A), Fiorentina heavily invested on players, meaning the amortisation of intangible asset (the player contract) had increased from €17.7 million to €24 million. However the club suffered from the 2006 Italian football scandal, which meant the club did not qualify for Europe. In 2007 Fiorentina almost broke-even, with a net loss of just €3,704,953. In the 2007 financial year the TV revenue increased after they qualified to the 2007–08 UEFA Cup. Despite qualifying to the 2008–09 UEFA Champions League, Fiorentina made a net loss of €9,179,484 in 2008 financial year after the increase in TV revenue was outweighed by the increase in wage. In the 2009 financial year, Fiorentina made a net profit of €4,442,803, largely due to the profit on selling players (€33,631,489 from players such as Felipe Melo, Giampaolo Pazzini and Zdravko Kuzmanović; increased from about €3.5 million in 2008). However it was also offset by the write-down of selling players (€6,062,545, from players such as Manuel da Costa, Arturo Lupoli and Davide Carcuro). After the club failed to qualify to Europe at the end of 2009–10 Serie A, as well as lack of player profit, Fiorentina turnover was decreased from €140,040,713 in 2009 to just €79,854,928, despite the wage bill also falling, la Viola still made a net loss of €9,604,353. In the 2011 financial year, the turnover slipped to €67,076,953, as the club's lack of capital gains from selling players and 2010 financial year still included the instalments from UEFA for participating 2009–10 UEFA Europa League. Furthermore, the gate income had dropped from €11,070,385 to €7,541,260. The wage bill did not fall much and in reverse the amortisation of transfer fee had sightly increased due to new signings. La Viola had savings in other costs but counter-weighted by huge €11,747,668 write-down for departed players, due to D'Agostino, Frey and Mutu, but the former would counter-weight by co-ownership financial income, which all made the operating cost remained high as worse as last year. Moreover, in 2010 the result was boosted by acquiring the asset from subsidiary (related to AC Fiorentina) and the re-valuation of its value in separate balance sheet. If deducting that income (€14,737,855), 2010 financial year was net loss 24,342,208 and 2011 result was worse with €8,131,876 only in separate balance sheet. In 2012, the club benefited from the sales of Matija Nastasić and Valon Behrami, followed by Stevan Jovetić and Adem Ljajić in 2013. In 2014, due to €28.4 million drop from the windfall profit of selling players, the club recorded their worst financial results since re-foundation, despite the fact the club maintained the same level of windfall profit, the result was still worse than in 2013. Moreover, Fiorentina also revealed that the club had a relevant football net income of minus €19.5 million in the first assessment period of UEFA Financial Fair Play Regulations in the 2013–14 season (in May 2014). (aggregate of 2012 and 2013 results), which within the limit of minus €45 million, as well as minus €25.5 million in assessment period 2014–15 (aggregate of 2012, 2013 and 2014 results). However, as the limit was reduced to minus €30 million in assessment period 2015–16, 2016–17 and 2017–18 season, the club had to achieve a relevant net income of positive €5.6 million in 2015 financial year. La Viola sold Juan Cuadrado to Chelsea in January 2015 for €30 million fee, to make the club eligible to 2016–17 edition of UEFA competitions.

https://en.wikipedia.org/wiki/Afrobeat

Afrobeat

Afrobeat is a music genre that involves the combination of elements of West African musical styles such as fuji music and highlife with American jazz and later soul and funk influences, with a focus on chanted vocals, complex intersecting rhythms, and percussion. The term was coined in the 1960s by Nigerian multi-instrumentalist and bandleader Fela Kuti, who is responsible for pioneering and popularizing the style both within and outside Nigeria. Distinct from Afrobeat is Afrobeats – a sound originating in West Africa in the 21st century, one that takes in diverse influences and is an eclectic combination of genres such as highlife, hip hop, house, jùjú, ndombolo, R&B and soca. The two genres, though often conflated, are not the same. History Afrobeat was developed in the late 1960s led by Fela Kuti who, with drummer Tony Allen, experimented with different contemporary music of the time. Afrobeat stemmed from Highlife, which began in Ghana in the early 1920s. During that time, Ghanaian musicians incorporated foreign influences like the foxtrot and calypso with Ghanaian rhythms such as osibisaba (Fante). Yoruba percussion and vocal traditions were incorporated as well. Highlife was associated with the local African aristocracy during the colonial period and was played by numerous bands including the Jazz Kings, Cape Coast Sugar Babies, and Accra Orchestra along the country's coast. This was the music Fela Kuti and Tony Allen played and listened to when they were young. In the late 1950s, Kuti left Lagos to study abroad at the London School of Music where he was exposed to jazz. He returned to Lagos and played a highlife-jazz hybrid, albeit, without commercial success. In 1969, Kuti and his band went on a trip to the U.S. and met Sandra Smith, a singer and former Black Panther. Sandra Smith (now known as Sandra Izsadore or Sandra Akanke Isidore) introduced Kuti to many writings of activists such as Martin Luther King Jr., Angela Davis, Jesse Jackson, and his biggest influence of all, Malcolm X. As Kuti was interested in African-American politics, Smith would inform him of current events. In return, Kuti would fill her in on African culture. Since Kuti stayed at Smith's house and was spending so much time with her, he started to re-evaluate his music. That was when Kuti noticed that he was not playing African music. From that day forward, Kuti changed his sound and the message behind his music. Upon arriving in Nigeria, Kuti also changed the name of his group to "Africa ′70". The new sound hailed from a club that he established called the Afrika Shrine. The band maintained a five-year residency at the Afrika Shrine from 1970 to 1975 while Afrobeat thrived among Nigerian youth. Also influential was , a Nigerian musician touring from Paris, France, with his Matumbo orchestra in the 1970s. The name was partially borne out of an attempt to distinguish Fela Kuti's music from the soul music of American artists such as James Brown. Prevalent in his and Lagbaja's music are native Nigerian harmonies and rhythms, taking different elements and combining, modernizing, and improvising upon them. Politics is essential to Afrobeat, since founder Kuti used social criticism to pave the way for social change. His message can be described as confrontational and controversial, which can be related to the political climate of most of the African countries in the 1970s, many of which were dealing with political injustice and military corruption while recovering from the transition from colonial governments to self-determination. As the genre spread throughout the African continent many bands took up the style. The recordings of these bands and their songs were rarely heard or exported outside the originating countries but many can now be found on compilation albums and CDs from specialist record shops. Influence Many jazz musicians have been attracted to Afrobeat. From Roy Ayers in the 1970s to Randy Weston in the 1990s, there have been collaborations that have resulted in albums such as Africa: Centre of the World by Roy Ayers, released on the Polydore label in 1981. In 1994, Branford Marsalis, the American jazz saxophonist, included samples of Fela's "Beasts of No Nation" on his Buckshot LeFonque album. Afrobeat has also profoundly influenced important contemporary producers and musicians, such as Brian Eno and David Byrne, who credit Fela Kuti as an essential influence. Both worked on Talking Heads' highly acclaimed 1980 album Remain in Light, which brought polyrhythmic Afrobeat influences to Western music. The new generation of DJs and musicians of the 2000s who have fallen in love with both Kuti's material and other rare releases have made compilations and remixes of these recordings, thus re-introducing the genre to new generations of listeners and fans of afropop and groove. In the late 1990s and early 2000s, a small Afrobeat scene began in Brooklyn, New York, with projects including Antibalas, The Daktaris and the Kokolo Afrobeat Orchestra. Since then, other artists like Zongo Junction have come onto the scene. Many others have cited Afrobeat as an influence like Daptone Records-adjacent groups The Budos Band and El Michels Affair. The horn section of Antibalas have been guest musicians on TV on the Radio's highly acclaimed 2008 album Dear Science, as well as on British band Foals' 2008 album Antidotes. Some Afrobeat influence can also be found in the music of Vampire Weekend and Paul Simon. In 2020, Antibalas was nominated for the Grammy Award for Best Global Music Album. Afrobeat artists of the 2000s and present, following in the footsteps of Fela Kuti, are for example his sons Femi Kuti and Seun Kuti, Franck Biyong & Massak (from Cameroon), Segun Damisa & the Afro-beat Crusaders, Newen Afrobeat (from Chile), Eddy Taylor & the Heartphones (from Cologne, Germany), Bantucrew, the Albinoid Afrobeat Orchestra / Albinoid Sound System (from Strasbourg, France), Abayomy Afrobeat Orquestra, Karl Hector & the Malcouns (from Munich, Germany), Afrodizz and Dele Sosimi and the ex-Africa '70 members Oghene Kologbo (guitar) with Afrobeat Academy, Nicholas Addo-Nettey (percussion), who is also known as , with Ridimtaksi (both based in Berlin, Germany). Namibian artist EES (Eric Sell) associates Afrobeat with reggae and kwaito. In 2009, the music label Knitting Factory Records (KFR) produced the Broadway musical Fela! The story showcased Kuti's "courage and incredible musical mastery" along with the story of his life. The show had 11 Tony nominations, receiving three for Best Costumes, Best Sound and Best Choreography. Fela! was on Broadway for 15 months and was produced by notables such as Shawn "Jay-Z " Carter and Will and Jada Pinkett-Smith. Many celebrities were noted as attending the shows, including Denzel Washington, Madonna, Sting, Spike Lee (who saw it eight times), Kofi Annan, and Michelle Obama. Michelle Williams, former singer of girl group Destiny's Child, was cast as the role of Sandra Izsadore.

Arithmetic function

In number theory, an arithmetic, arithmetical, or number-theoretic function is for most authors any function f(n) whose domain is the positive integers and whose range is a subset of the complex numbers. Hardy & Wright include in their definition the requirement that an arithmetical function "expresses some arithmetical property of n". An example of an arithmetic function is the divisor function whose value at a positive integer n is equal to the number of divisors of n. There is a larger class of number-theoretic functions that do not fit the above definition, for example, the prime-counting functions. This article provides links to functions of both classes. Arithmetic functions are often extremely irregular (see table), but some of them have series expansions in terms of Ramanujan's sum. Multiplicative and additive functions An arithmetic function a is completely additive if a(mn) = a(m) + a(n) for all natural numbers m and n; completely multiplicative if a(mn) = a(m)a(n) for all natural numbers m and n; Two whole numbers m and n are called coprime if their greatest common divisor is 1, that is, if there is no prime number that divides both of them. Then an arithmetic function a is additive if a(mn) = a(m) + a(n) for all coprime natural numbers m and n; multiplicative if a(mn) = a(m)a(n) for all coprime natural numbers m and n. Notation   and     mean that the sum or product is over all prime numbers: Similarly,     and     mean that the sum or product is over all prime powers with strictly positive exponent (so k = 0 is not included):   and     mean that the sum or product is over all positive divisors of n, including 1 and n. For example, if n = 12, The notations can be combined:     and     mean that the sum or product is over all prime divisors of n. For example, if n = 18, and similarly     and     mean that the sum or product is over all prime powers dividing n. For example, if n = 24, Ω(n), ω(n), νp(n) – prime power decomposition The fundamental theorem of arithmetic states that any positive integer n can be represented uniquely as a product of powers of primes:     where p1 < p2 < ... < pk are primes and the aj are positive integers. (1 is given by the empty product.) It is often convenient to write this as an infinite product over all the primes, where all but a finite number have a zero exponent. Define the p-adic valuation νp(n) to be the exponent of the highest power of the prime p that divides n. That is, if p is one of the pi then νp(n) = ai, otherwise it is zero. Then In terms of the above the prime omega functions ω and Ω are defined by ω(n) = k, Ω(n) = a1 + a2 + ... + ak. To avoid repetition, whenever possible formulas for the functions listed in this article are given in terms of n and the corresponding pi, ai, ω, and Ω. Multiplicative functions σk(n), τ(n), d(n) – divisor sums σk(n) is the sum of the kth powers of the positive divisors of n, including 1 and n, where k is a complex number. σ1(n), the sum of the (positive) divisors of n, is usually denoted by σ(n). Since a positive number to the zero power is one, σ0(n) is therefore the number of (positive) divisors of n; it is usually denoted by d(n) or τ(n) (for the German Teiler = divisors). Setting k = 0 in the second product gives φ(n) – Euler totient function φ(n), the Euler totient function, is the number of positive integers not greater than n that are coprime to n. Jk(n) – Jordan totient function Jk(n), the Jordan totient function, is the number of k-tuples of positive integers all less than or equal to n that form a coprime (k + 1)-tuple together with n. It is a generalization of Euler's totient, . μ(n) – Möbius function μ(n), the Möbius function, is important because of the Möbius inversion formula. See Dirichlet convolution, below. This implies that μ(1) = 1. (Because Ω(1) = ω(1) = 0.) τ(n) – Ramanujan tau function τ(n), the Ramanujan tau function, is defined by its generating function identity: Although it is hard to say exactly what "arithmetical property of n" it "expresses", (τ(n) is (2π)−12 times the nth Fourier coefficient in the q-expansion of the modular discriminant function) it is included among the arithmetical functions because it is multiplicative and it occurs in identities involving certain σk(n) and rk(n) functions (because these are also coefficients in the expansion of modular forms). cq(n) – Ramanujan's sum cq(n), Ramanujan's sum, is the sum of the nth powers of the primitive qth roots of unity: Even though it is defined as a sum of complex numbers (irrational for most values of q), it is an integer. For a fixed value of n it is multiplicative in q: If q and r are coprime, then ψ(n) - Dedekind psi function The Dedekind psi function, used in the theory of modular functions, is defined by the formula Completely multiplicative functions λ(n) – Liouville function λ(n), the Liouville function, is defined by χ(n) – characters All Dirichlet characters χ(n) are completely multiplicative. Two characters have special notations: The principal character (mod n) is denoted by χ0(a) (or χ1(a)). It is defined as The quadratic character (mod n) is denoted by the Jacobi symbol for odd n (it is not defined for even n.): In this formula is the Legendre symbol, defined for all integers a and all odd primes p by Following the normal convention for the empty product, Additive functions ω(n) – distinct prime divisors ω(n), defined above as the number of distinct primes dividing n, is additive (see Prime omega function). Completely additive functions Ω(n) – prime divisors Ω(n), defined above as the number of prime factors of n counted with multiplicities, is completely additive (see Prime omega function). νp(n) – p-adic valuation of an integer n For a fixed prime p, νp(n), defined above as the exponent of the largest power of p dividing n, is completely additive. Neither multiplicative nor additive (x), Π(x), θ(x), ψ(x) – prime-counting functions These important functions (which are not arithmetic functions) are defined for non-negative real arguments, and are used in the various statements and proofs of the prime number theorem. They are summation functions (see the main section just below) of arithmetic functions which are neither multiplicative nor additive. (x), the prime-counting function, is the number of primes not exceeding x. It is the summation function of the characteristic function of the prime numbers. A related function counts prime powers with weight 1 for primes, 1/2 for their squares, 1/3 for cubes, ... It is the summation function of the arithmetic function which takes the value 1/k on integers which are the k-th power of some prime number, and the value 0 on other integers. θ(x) and ψ(x), the Chebyshev functions, are defined as sums of the natural logarithms of the primes not exceeding x. The Chebyshev function ψ(x) is the summation function of the von Mangoldt function just below. Λ(n) – von Mangoldt function Λ(n), the von Mangoldt function, is 0 unless the argument n is a prime power , in which case it is the natural log of the prime p: p(n) – partition function p(n), the partition function, is the number of ways of representing n as a sum of positive integers, where two representations with the same summands in a different order are not counted as being different: λ(n) – Carmichael function λ(n), the Carmichael function, is the smallest positive number such that   for all a coprime to n. Equivalently, it is the least common multiple of the orders of the elements of the multiplicative group of integers modulo n. For powers of odd primes and for 2 and 4, λ(n) is equal to the Euler totient function of n; for powers of 2 greater than 4 it is equal to one half of the Euler totient function of n: and for general n it is the least common multiple of λ of each of the prime power factors of n: h(n) – Class number h(n), the class number function, is the order of the ideal class group of an algebraic extension of the rationals with discriminant n. The notation is ambiguous, as there are in general many extensions with the same discriminant. See quadratic field and cyclotomic field for classical examples. rk(n) – Sum of k squares rk(n) is the number of ways n can be represented as the sum of k squares, where representations that differ only in the order of the summands or in the signs of the square roots are counted as different. D(n) – Arithmetic derivative Using the Heaviside notation for the derivative, D(n) is a function such that if n prime, and (Product rule) Summation functions Given an arithmetic function a(n), its summation function A(x) is defined by A can be regarded as a function of a real variable. Given a positive integer m, A is constant along open intervals m < x < m + 1, and has a jump discontinuity at each integer for which a(m) ≠ 0. Since such functions are often represented by series and integrals, to achieve pointwise convergence it is usual to define the value at the discontinuities as the average of the values to the left and right: Individual values of arithmetic functions may fluctuate wildly – as in most of the above examples. Summation functions "smooth out" these fluctuations. In some cases it may be possible to find asymptotic behaviour for the summation function for large x. A classical example of this phenomenon is given by the divisor summatory function, the summation function of d(n), the number of divisors of n: An average order of an arithmetic function is some simpler or better-understood function which has the same summation function asymptotically, and hence takes the same values "on average". We say that g is an average order of f if as x tends to infinity. The example above shows that d(n) has the average order log(n). Dirichlet convolution Given an arithmetic function a(n), let Fa(s), for complex s, be the function defined by the corresponding Dirichlet series (where it converges): Fa(s) is called a generating function of a(n). The simplest such series, corresponding to the constant function a(n) = 1 for all n, is ς(s) the Riemann zeta function. The generating function of the Möbius function is the inverse of the zeta function: Consider two arithmetic functions a and b and their respective generating functions Fa(s) and Fb(s). The product Fa(s)Fb(s) can be computed as follows: It is a straightforward exercise to show that if c(n) is defined by then This function c is called the Dirichlet convolution of a and b, and is denoted by . A particularly important case is convolution with the constant function a(n) = 1 for all n, corresponding to multiplying the generating function by the zeta function: Multiplying by the inverse of the zeta function gives the Möbius inversion formula: If f is multiplicative, then so is g. If f is completely multiplicative, then g is multiplicative, but may or may not be completely multiplicative. Relations among the functions There are a great many formulas connecting arithmetical functions with each other and with the functions of analysis, especially powers, roots, and the exponential and log functions. The page divisor sum identities contains many more generalized and related examples of identities involving arithmetic functions. Here are a few examples: Dirichlet convolutions     where λ is the Liouville function.             Möbius inversion             Möbius inversion                         Möbius inversion             Möbius inversion             Möbius inversion           where λ is the Liouville function.             Möbius inversion Sums of squares For all     (Lagrange's four-square theorem). where the Kronecker symbol has the values There is a formula for r3 in the section on class numbers below.     where .     where Define the function as That is, if n is odd, is the sum of the kth powers of the divisors of n, that is, and if n is even it is the sum of the kth powers of the even divisors of n minus the sum of the kth powers of the odd divisors of n.     Adopt the convention that Ramanujan's if x is not an integer. Divisor sum convolutions Here "convolution" does not mean "Dirichlet convolution" but instead refers to the formula for the coefficients of the product of two power series: The sequence is called the convolution or the Cauchy product of the sequences an and bn. These formulas may be proved analytically (see Eisenstein series) or by elementary methods.                     where τ(n) is Ramanujan's function.     Since σk(n) (for natural number k) and τ(n) are integers, the above formulas can be used to prove congruences for the functions. See Ramanujan tau function for some examples. Extend the domain of the partition function by setting       This recurrence can be used to compute p(n). Class number related Peter Gustav Lejeune Dirichlet discovered formulas that relate the class number h of quadratic number fields to the Jacobi symbol. An integer D is called a fundamental discriminant if it is the discriminant of a quadratic number field. This is equivalent to D ≠ 1 and either a) D is squarefree and D ≡ 1 (mod 4) or b) D ≡ 0 (mod 4), D/4 is squarefree, and D/4 ≡ 2 or 3 (mod 4). Extend the Jacobi symbol to accept even numbers in the "denominator" by defining the Kronecker symbol: Then if D < −4 is a fundamental discriminant There is also a formula relating r3 and h. Again, let D be a fundamental discriminant, D < −4. Then Prime-count related Let   be the nth harmonic number.   Then   is true for every natural number n if and only if the Riemann hypothesis is true.     The Riemann hypothesis is also equivalent to the statement that, for all n > 5040,     (where γ is the Euler–Mascheroni constant).     This is Robin's theorem. Menon's identity In 1965 P Kesava Menon proved This has been generalized by a number of mathematicians. For example, B. Sury N. Rao where a1, a2, ..., as are integers, gcd(a1, a2, ..., as, n) = 1.

ANSI C

ANSI C, ISO C, and Standard C are successive standards for the C programming language published by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO). Historically, the names referred specifically to the original and best-supported version of the standard (known as C89 or C90). Software developers writing in C are encouraged to conform to the standards, as doing so helps portability between compilers. History and outlook The first standard for C was published by ANSI. Although this document was subsequently adopted by International Organization for Standardization (ISO) and subsequent revisions published by ISO have been adopted by ANSI, "ANSI C" is still used to refer to the standard. While some software developers use the term ISO C, others are standards-body neutral and use Standard C. Standardizing C In 1983, the American National Standards Institute formed a committee, X3J11, to establish a standard specification of C. In 1985, the first Standard Draft was released, sometimes referred to as C85. In 1986, another Draft Standard was released, sometimes referred to as C86. The prerelease Standard C was published in 1988, and sometimes referred to as C88. C89 The ANSI standard was completed in 1989 and ratified as ANSI X3.159-1989 "Programming Language C." This version of the language is often referred to as "ANSI C". Later on sometimes the label "C89" is used to distinguish it from C90 but using the same labeling method. C90 The same standard as C89 was ratified by the International Organization for Standardization as ISO/IEC 9899:1990, with only formatting changes, which is sometimes referred to as C90. Therefore, the terms "C89" and "C90" refer to essentially the same language. This standard has been withdrawn by both ANSI/INCITS and ISO/IEC. C95 In 1995, the ISO published an extension, called Amendment 1, for the ANSI-C standard. Its full name finally was ISO/IEC 9899:1990/AMD1:1995 or nicknamed C95. Aside from error correction there were further changes to the language capabilities, such as: Improved multi-byte and wide character support in the standard library, introducing <wchar.h> and <wctype.h> as well as multi-byte I/O Addition of digraphs to the language Specification of standard macros for the alternative specification of operators, e.g. and for && Specification of the standard macro __STDC_VERSION__ In addition to the amendment, two technical corrigenda were published by ISO for C90: ISO/IEC 9899:1990/Cor 1:1994 TCOR1 in 1994 ISO/IEC 9899:1990/Cor 2:1996 in 1996 Preprocessor test for C95 compatibility #if defined(__STDC_VERSION__) && __STDC_VERSION__ >= 199409L /* C95 compatible source code. */ #elif defined() /* C89 compatible source code. */ #endif C99 In March 2000, ANSI adopted the ISO/IEC 9899:1999 standard. This standard is commonly referred to as C99. Some notable additions to the previous standard include: New built-in data types: long long, _Bool, _Complex, and _Imaginary Several new core language features, including static array indices, designated initializers, compound literals, variable-length arrays, flexible array members, variadic macros, and restrict keyword Several new library headers, including stdint.h, <tgmath.h>, fenv.h, <complex.h> Improved compatibility with several C++ features, including inline functions, single-line comments with //, mixing declarations and code, and universal character names in identifiers Removed several dangerous C89 language features such as implicit function declarations and implicit int Three technical corrigenda were published by ISO for C99: ISO/IEC 9899:1999/Cor 1:2001(E) ISO/IEC 9899:1999/Cor 2:2004(E) ISO/IEC 9899:1999/Cor 3:2007(E), notable for deprecating the standard library function gets This standard has been withdrawn by both ANSI/INCITS and ISO/IEC in favour of C11. C11 C11 was officially ratified and published on December 8, 2011. Notable features include improved Unicode support, type-generic expressions using the new _Generic keyword, a cross-platform multi-threading API (threads.h), and atomic types support in both core language and the library (stdatomic.h). One technical corrigendum has been published by ISO for C11: ISO/IEC 9899:2011/Cor 1:2012 C17 , "C17" is the current standard for the C programming language. C17 addresses defects in C11 without introducing new language features. C2x C2x is an informal name for the next (after C17) major C language standard revision. Other related ISO publications As part of the standardization process, ISO also publishes technical reports and specifications related to the C language: ISO/IEC TR 19769:2004, on library extensions to support Unicode transformation formats, integrated into C11 ISO/IEC TR 24731-1:2007, on library extensions to support bounds-checked interfaces, integrated into C11 ISO/IEC TR 18037:2008, on embedded C extensions ISO/IEC TR 24732:2009, on decimal floating point arithmetic, superseded by ISO/IEC TS 18661-2:2015 ISO/IEC TR 24747:2009, on special mathematical functions, ISO/IEC TR 24731-2:2010, on library extensions to support dynamic allocation functions ISO/IEC TS 17961:2013, on secure coding in C ISO/IEC TS 18661-1:2014, on IEC 60559:2011-compatible binary floating-point arithmetic ISO/IEC TS 18661-2:2015, on IEC 60559:2011-compatible decimal floating point arithmetic ISO/IEC TS 18661-3:2015, on IEC 60559:2011-compatible interchange and extended floating-point types ISO/IEC TS 18661-4:2015, on IEC 60559:2011-compatible supplementary functions More technical specifications are in development and pending approval, including the fifth and final part of TS 18661, a software transactional memory specification, and parallel library extensions. Support from major compilers ANSI C is now supported by almost all the widely used compilers. GCC and Clang are two major C compilers popular today, both are based on the C11 with updates including changes from later specifications such as C17 and C18. Any source code written only in standard C and without any hardware dependent assumptions is virtually guaranteed to compile correctly on any platform with a conforming C implementation. Without such precautions, most programs may compile only on a certain platform or with a particular compiler, due, for example, to the use of non-standard libraries, such as GUI libraries, or to the reliance on compiler- or platform-specific attributes such as the exact size of certain data types and byte endianness. Compliance detectability To mitigate the differences between K&R C and the ANSI C standard, the ("standard c") macro can be used to split code into ANSI and K&R sections. #if defined() && extern int getopt(int, char * const *, const char *); #else extern int getopt(); #endif In the above example, a prototype is used in a function declaration for ANSI compliant implementations, while an obsolescent non-prototype declaration is used otherwise. Those are still ANSI-compliant as of C99. Note how this code checks both definition and evaluation: this is because some implementations may set to zero to indicate non-ANSI compliance.

Alien and Sedition Acts

In 1798, President John Adams signed the Alien and Sedition Acts, which were passed by the Federalist-dominated 5th United States Congress. They made it harder for an immigrant to become a citizen (Naturalization Act), allowed the president to imprison and deport non-citizens who were known as dangerous ("An Act Concerning Aliens", also known as the "Alien Friends Act" of 1798) or who were from a hostile nation ("Alien Enemy Act" of 1798), and criminalized making 'false statements' critical of the federal government ("Sedition Act" of 1798). The "Alien Friends Act" expired two years after its passage, and the "Sedition Act" expired on 3 March 1801, while the "Naturalization Act" and "Alien Enemies Act" had no expiration clause. The Federalists argued that the bills strengthened national security during the Quasi-War, an undeclared naval war with France from 1798 to 1800. Critics argued that they were primarily an attempt to suppress voters who disagreed with the Federalist party and its teachings, and violated the right of freedom of speech in the First Amendment to the U.S. Constitution. The Naturalization Act increased the residency requirement for American citizenship from five to fourteen years. At the time, the majority of immigrants supported Thomas Jefferson and the Democratic-Republicans, the political opponents of the Federalists. The Alien Friends Act allowed the president to imprison or deport aliens considered "dangerous to the peace and safety of the United States" at any time, while the Alien Enemies Act authorized the president to do the same to any male citizen of a hostile nation above the age of fourteen during times of war. Lastly, the controversial Sedition Act restricted speech that was critical of the federal government. Under the Sedition Act, the Federalists allowed people who were accused of violating the sedition laws to use truth as a defense. The Sedition Act resulted in the prosecution and conviction of many Jeffersonian newspaper owners who disagreed with the government. The acts were denounced by Democratic-Republicans and ultimately helped them to victory in the 1800 election, when Thomas Jefferson defeated the incumbent, President Adams. The Sedition Act and the Alien Friends Act were allowed to expire in 1800 and 1801, respectively. The Alien Enemies Act, however, remains in effect as Chapter 3; Sections 21–24 of Title 50 of the United States Code. It was used by the government to identify and imprison allegedly "dangerous enemy" aliens from Germany, Japan, and Italy in World War II. (This was separate from the Japanese internment camps used to remove people of Japanese descent from the West Coast.) After the war they were deported to their home countries. In 1948 the Supreme Court determined that presidential powers under the acts continued after cessation of hostilities until there was a peace treaty with the hostile nation. The revised Alien Enemies Act remains in effect today. History The Federalists' fear of the opposing Democratic-Republican Party reached new heights with the Democratic-Republicans' support of France in the midst of the French Revolution. Some appeared to desire a similar revolution in the United States to overthrow the government and social structure. Newspapers sympathizing with each side exacerbated the tensions by accusing the other side's leaders of corruption, incompetence, and treason. As the unrest sweeping Europe threatened to spread to the United States, calls for secession started to rise, and the fledgling nation seemed ready to tear itself apart. Some of this agitation was seen by Federalists as having been caused by French and French-sympathizing immigrants. The Alien Act and the Sedition Act were meant to guard against this perceived threat of anarchy. The Acts were highly controversial at the time, especially the Sedition Act. The Sedition Act, which was signed into law by Adams on July 14, 1798, was hotly debated in the Federalist-controlled Congress and passed only after multiple amendments softening its terms, such as enabling defendants to argue in their defense that their statements had been true. Still, it passed the House only after three votes and another amendment causing it to automatically expire in March 1801. They continued to be loudly protested and were a major political issue in the election of 1800. Opposition to them resulted in the also-controversial Virginia and Kentucky Resolutions, authored by James Madison and Thomas Jefferson. Prominent prosecutions under the Sedition Act include: James Thomson Callender, a British subject, had been expelled from Great Britain for his political writings. Living first in Philadelphia, then seeking refuge close by in Virginia, he wrote a book titled The Prospect Before Us (read and approved by Vice President Jefferson before publication) in which he called the Adams administration a "continual tempest of malignant passions" and the President a "repulsive pedant, a gross hypocrite and an unprincipled oppressor." Callender, already residing in Virginia and writing for the Richmond Examiner, was indicted in mid-1800 under the Sedition Act and convicted, fined $200, and sentenced to nine months in jail. Matthew Lyon was a Democratic-Republican congressman from Vermont. He was the first individual to be placed on trial under the Alien and Sedition Acts. He was indicted in 1800 for an essay he had written in the Vermont Journal accusing the administration of "ridiculous pomp, foolish adulation, and selfish avarice." While awaiting trial, Lyon commenced publication of Lyon's Republican Magazine, subtitled "The Scourge of Aristocracy". At trial, he was fined $1,000 and sentenced to four months in jail. After his release, he returned to Congress. Benjamin Franklin Bache was editor of the Philadelphia Aurora, a Democratic-Republican newspaper. Bache had accused George Washington of incompetence and financial irregularities, and "the blind, bald, crippled, toothless, querulous Adams" of nepotism and monarchical ambition. He was arrested in 1798 under the Sedition Act, but he died of yellow fever before trial. Anthony Haswell was an English immigrant and a printer of the Jeffersonian Vermont Gazette. Haswell had reprinted from the Aurora Bache's claim that the federal government employed Tories, also publishing an advertisement from Lyon's sons for a lottery to raise money for his fine that decried Lyon's oppression by jailers exercising "usurped powers". Haswell was found guilty of seditious libel by judge William Paterson, and sentenced to a two-month imprisonment and a $200 fine. Luther Baldwin was indicted, convicted, and fined $100 for a drunken incident that occurred during a visit by President Adams to Newark, New Jersey. Upon hearing a gun report during a parade, he yelled "I hope it hit Adams in the arse." In November 1798, David Brown led a group in Dedham, Massachusetts, including Benjamin Fairbanks, in setting up a liberty pole with the words, "No Stamp Act, No Sedition Act, No Alien Bills, No Land Tax, downfall to the Tyrants of America; peace and retirement to the President; Long Live the Vice President." Brown was arrested in Andover, Massachusetts, but because he could not afford the $4,000 bail, he was taken to Salem for trial. Brown was tried in June 1799. Brown pleaded guilty, but Justice Samuel Chase asked him to name others who had assisted him. Brown refused, was fined $480 (), and sentenced to eighteen months in prison, the most severe sentence imposed under the Sedition Act. Contemporaneous reaction After the passage of the highly unpopular Alien and Sedition Acts, protests occurred across the country, with some of the largest being seen in Kentucky, where the crowds were so large they filled the streets and the entire town square. Noting the outrage among the populace, the Democratic-Republicans made the Alien and Sedition Acts an important issue in the 1800 election campaign. Upon assuming the Presidency, Thomas Jefferson pardoned those still serving sentences under the Sedition Act, and Congress soon repaid their fines. It has been said that the Alien Acts were aimed at Albert Gallatin, and the Sedition Act aimed at Benjamin Bache's Aurora. While government authorities prepared lists of aliens for deportation, many aliens fled the country during the debate over the Alien and Sedition Acts, and Adams never signed a deportation order. The Virginia and Kentucky state legislatures also passed the Kentucky and Virginia Resolutions, secretly authored by Thomas Jefferson and James Madison, denouncing the federal legislation. While the eventual resolutions followed Madison in advocating "interposition", Jefferson's initial draft would have nullified the Acts and even threatened secession. Jefferson's biographer Dumas Malone argued that this might have gotten Jefferson impeached for treason, had his actions become known at the time. In writing the Kentucky Resolutions, Jefferson warned that, "unless arrested at the threshold", the Alien and Sedition Acts would "necessarily drive these states into revolution and blood". The Alien and Sedition Acts were never appealed to the Supreme Court, whose power of judicial review was not clearly established until Marbury v. Madison in 1803. Subsequent mentions in Supreme Court opinions beginning in the mid-20th century have assumed that the Sedition Act would today be found unconstitutional. The Alien Enemies Act in the 20th and 21st centuries The Alien Enemies Acts remained in effect at the outset of World War I and remains U.S. law today. It was recodified to be part of the US war and national defense statutes (50 USC 21–24). On December 7, 1941, responding to the bombing of Pearl Harbor, President Franklin Delano Roosevelt used the authority of the revised Alien Enemies Act to issue presidential proclamations #2525 (Alien Enemies – Japanese), #2526 (Alien Enemies – German), and #2527 (Alien Enemies – Italian), to apprehend, restrain, secure and remove Japanese, German, and Italian non-citizens. On February 19, 1942, citing authority of the wartime powers of the president and commander in chief, Roosevelt issued Executive Order 9066, authorizing the Secretary of War to prescribe military areas and giving him authority that superseded the authority of other executives under Proclamations 2525–7. EO 9066 led to the internment of Japanese Americans, whereby over 110,000 people of Japanese ancestry, 62% of whom were United States citizens, not aliens, living on the Pacific coast were forcibly relocated and forced to live in camps in the interior of the country. Hostilities with Germany and Italy ended in May 1945, and with Japan that August. Alien enemies, and U.S. citizens, continued to be interned. On July 14, 1945, President Harry S. Truman issued Presidential Proclamation 2655, titled "Removal of Alien Enemies". The proclamation gave the Attorney General authority regarding enemy aliens within the continental United States, to decide whether they are "dangerous to the public peace and safety of the United States", to order them removed, and to create regulations governing their removal. The proclamation cited the revised Alien Enemies Act (50 U.S.C. 21–24) as to powers of the President to make public proclamation regarding "subjects of the hostile nation" more than fourteen years old and living inside the United States but not naturalized, to remove them as alien enemies, and to determine the means of removal. On September 8, 1945, Truman issued Presidential Proclamation 2662, titled "Removal of Alien Enemies". The revised Alien Enemies Act (50 U.S.C. 21–24) was cited as to removal of alien enemies in the interest of the public safety. The United States had agreed, at a conference in Rio de Janeiro in 1942, to assume responsibility for the restraint and repatriation of dangerous alien enemies to be sent to the United States from Latin American republics. In another inter-American conference in Mexico City on March 8, 1945, North and South American governments resolved to recommended adoption of measures to prevent aliens of hostile nations who were deemed to be security threats or threats to welfare from remaining in North or South America. Truman gave authority to the Secretary of State to determine if alien enemies in the United States who were sent to the United States from Latin America, or who were in the United States illegally, endangered the welfare or security of the country. The Secretary of State was given power to remove them "to destinations outside the limits of the Western Hemisphere", to the former enemy territory of the governments to whose "principles of which (the alien enemies) have adhered". The Department of Justice was directed to assist the Secretary of State in their prompt removal. On April 10, 1946, Truman issued Presidential Proclamation 2685, titled "Removal of Alien Enemies", citing the revised Alien Enemies Act (50 U.S.C. 21–24) as to its provision for the "removal from the United States of alien enemies in the interest of the public safety". Truman proclaimed regulations that were in addition to and supplemented other "regulations affecting the restraint and removal of alien enemies". As to alien enemies who had been brought into the continental United States from Latin America after December 1941, the proclamation gave the Secretary of State authority to decide if their presence was "prejudicial to the future security or welfare of the Americas", and to make regulations for their removal. 30 days was set as the reasonable time for them to "effect the recovery, disposal, and removal of (their) goods and effects, and for (their) departure". In 1947 New York's Ellis Island continued to incarcerate hundreds of ethnic Germans. Fort Lincoln was a large internment camp still holding internees in North Dakota. North Dakota was represented by controversial Senator William "Wild Bill" Langer. Langer introduced a bill (S. 1749) "for the relief of all persons detained as enemy aliens", and directing the U.S. Attorney General to cancel "outstanding warrants of arrest, removal, or deportation" for many German aliens still interned, listing many by name, and all of those detained by the Immigration and Naturalization Service, which was under the Department of Justice. It directed the INS not to issue any more warrants or orders, if their only basis was the original warrants of arrest. The bill never passed. The Attorney General gave up plenary jurisdiction over the last internee on Ellis Island late in 1948. In Ludecke v. Watkins (1948), the Supreme Court interpreted the time of release under the Alien Enemies Act. German alien Kurt G. W. Ludecke was detained in 1941, under Proclamation 2526. and continued to be held after cessation of hostilities. In 1947, Ludecke petitioned for a writ of habeas corpus to order his release, after the Attorney General ordered him deported. The court ruled 5–4 to release Ludecke, but also found that the Alien Enemies Act allowed for detainment beyond the time hostilities ceased, until an actual treaty was signed with the hostile nation or government. In 1988, Congress introduced the Civil Liberties Act of 1988, whose purpose amongst others was to acknowledge and apologize for actions of the U.S. against individuals of Japanese ancestry during World War II. The statement from Congress agreed with the Commission on Wartime Relocation and Internment of Civilians, that "a grave injustice was done to both citizens and permanent resident aliens of Japanese ... without adequate security reasons and without any acts of espionage or sabotage documented by the Commission, and were motivated largely by racial prejudice, wartime hysteria, and a failure of political leadership". In 2015, presidential candidate Donald Trump called for a temporary ban on any Muslims entering the country in response to the San Bernardino attack. He later shifted his proposal, and made a proposal to ban people from seven predominantly Muslim countries from entering the United States; Roosevelt's application of the Alien Enemies Act was cited as a possible justification. The proposal created international controversy, drawing criticism from foreign heads of state that have historically remained uninvolved in United States presidential elections. A former Reagan Administration aide noted that, despite criticism of Trump's proposal to invoke the law, "the Alien Enemies Act ... is still on the books ... (and people) in Congress for many decades (haven't) repealed the law ... (nor has) Barack Obama". Other critics claimed that the proposal violated founding principles, and was unconstitutional for singling out a religion, and not a hostile nation. They included the Pentagon and others, who argued that the proposal (and its citation of the Alien Enemies proclamations as authority) played into the ISIL narrative that the United States was at war with the entire Muslim religion (not just with ISIL and other terrorist entities). On June 26, 2018, in the 5–4 decision Trump v. Hawaii, the U.S. Supreme Court upheld Presidential Proclamation 9645, the third version of President Trump's travel ban, with the majority opinion being written by Chief Justice John Roberts.

https://en.wikipedia.org/wiki/Antinomy

Antinomy

Antinomy (Greek ἀντί, antí, "against, in opposition to", and νόμος, nómos, "law") refers to a real or apparent mutual incompatibility of two laws. It is a term used in logic and epistemology, particularly in the philosophy of Kant. There are many examples of antinomy. A self-contradictory phrase such as "There is no absolute truth" can be considered an antinomy because this statement is suggesting in itself to be an absolute truth, and therefore denies itself any truth in its statement. A paradox such as "this sentence is false" can also be considered to be an antinomy; for the sentence to be true, it must be false, and vice versa. Kant's use The term acquired a special significance in the philosophy of Immanuel Kant (1724–1804), who used it to describe the equally rational but contradictory results of applying to the universe of pure thought the categories or criteria of reason that are proper to the universe of sensible perception or experience (phenomena). Empirical reason cannot here play the role of establishing rational truths because it goes beyond possible experience and is applied to the sphere of that which transcends it. For Kant there are four antinomies, connected with: the limitation of the universe in respect to space and time the theory that the whole consists of indivisible atoms (whereas, in fact, none such exist) the problem of free will in relation to universal causality the existence of a universal being In each antinomy, a thesis is contradicted by an antithesis. For example: in the first antinomy, Kant proves the thesis that time must have a beginning by showing that if time had no beginning, then an infinity would have elapsed up until the present moment. This is a manifest contradiction because infinity cannot, by definition, be completed by "successive synthesis"—yet just such a finalizing synthesis would be required by the view that time is infinite; so the thesis is proven. Then he proves the antithesis, that time has no beginning, by showing that if time had a beginning, then there must have been "empty time" out of which time arose. This is incoherent (for Kant) for the following reason: Since, necessarily, no time elapses in this pretemporal void, then there could be no alteration, and therefore nothing (including time) would ever come to be: so the antithesis is proven. Reason makes equal claim to each proof, since they are both correct, so the question of the limits of time must be regarded as meaningless. This was part of Kant's critical program of determining limits to science and philosophical inquiry. These contradictions are inherent in reason when it is applied to the world as it is in itself, independently of any perception of it (this has to do with the distinction between phenomena and noumena). Kant's goal in his critical philosophy was to identify what claims are and are not justified, and the antinomies are a particularly illustrative example of his larger project. Marx's use In Capital Volume One, in the chapter entitled "The Working Day", Karl Marx claims that capitalist production sustains "the assertion of a right to an unlimited working day, and the assertion of a right to a limited working day, both with equal justification". Furner emphasizes that the thesis and antithesis of this antinomy are not contradictory opposites, but rather "consist in the assertion of rights to states of affairs that are contradictory opposites".

https://en.wikipedia.org/wiki/Ascending%20chain%20condition

Ascending chain condition

In mathematics, the ascending chain condition (ACC) and descending chain condition (DCC) are finiteness properties satisfied by some algebraic structures, most importantly ideals in certain commutative rings. These conditions played an important role in the development of the structure theory of commutative rings in the works of David Hilbert, Emmy Noether, and Emil Artin. The conditions themselves can be stated in an abstract form, so that they make sense for any partially ordered set. This point of view is useful in abstract algebraic dimension theory due to Gabriel and Rentschler. Definition A partially ordered set (poset) P is said to satisfy the ascending chain condition (ACC) if no infinite strictly ascending sequence of elements of P exists. Equivalently, every weakly ascending sequence of elements of P eventually stabilizes, meaning that there exists a positive integer n such that Similarly, P is said to satisfy the descending chain condition (DCC) if there is no infinite descending chain of elements of P. Equivalently, every weakly descending sequence of elements of P eventually stabilizes. Comments Assuming the axiom of dependent choice, the descending chain condition on (possibly infinite) poset P is equivalent to P being well-founded: every nonempty subset of P has a minimal element (also called the minimal condition or minimum condition). A totally ordered set that is well-founded is a well-ordered set. Similarly, the ascending chain condition is equivalent to P being converse well-founded (again, assuming dependent choice): every nonempty subset of P has a maximal element (the maximal condition or maximum condition). Every finite poset satisfies both the ascending and descending chain conditions, and thus is both well-founded and converse well-founded. Example Consider the ring of integers. Each ideal of consists of all multiples of some number . For example, the ideal consists of all multiples of . Let be the ideal consisting of all multiples of . The ideal is contained inside the ideal , since every multiple of is also a multiple of . In turn, the ideal is contained in the ideal , since every multiple of is a multiple of . However, at this point there is no larger ideal; we have "topped out" at . In general, if are ideals of such that is contained in , is contained in , and so on, then there is some for which all . That is, after some point all the ideals are equal to each other. Therefore, the ideals of satisfy the ascending chain condition, where ideals are ordered by set inclusion. Hence is a Noetherian ring. See also Artinian Ascending chain condition for principal ideals Krull dimension Maximal condition on congruences Noetherian Notes References Atiyah, M. F., and I. G.

Adin Steinsaltz

Rabbi Adin Even-Israel Steinsaltz (11 July 19377 August 2020) () was an Israeli Chabad Chasidic rabbi, teacher, philosopher, social critic, author, translator and publisher. His Steinsaltz edition of the Talmud was originally published in modern Hebrew, with a running commentary to facilitate learning, and has also been translated into English, French, Russian, and Spanish. Beginning in 1989, Steinsaltz published several tractates in Hebrew and English of the Babylonian (Bavli) Talmud in an English-Hebrew edition. The first volume of a new English-Hebrew edition, the Koren Talmud Bavli, was released in May 2012, and has since been brought to completion. Steinsaltz was a recipient of the Israel Prize for Jewish Studies (1988), the President's Medal (2012), and the Yakir Yerushalayim prize (2017). Steinsaltz died in Jerusalem on 7 August 2020, from acute pneumonia. Biography Adin Steinsaltz was born in Jerusalem on 11 July 1937 to Avraham Steinsaltz and Leah (née Krokovitz). His father was a great-grandson of the first Slonimer Rebbe, Avrohom Weinberg, and was a student of Hillel Zeitlin. Avraham and Leah Steinsaltz met through Zeitlin. They immigrated to Mandatory Palestine in 1924. Avraham Steinsaltz, a devoted communist and member of Lehi, went to Spain in 1936 to fight with the International Brigades in the Spanish Civil War. Adin was born the following year. Steinsaltz became a baal teshuva during his teenage years and learned from Rabbi Shmuel Elazar Heilprin (Rosh yeshiva of Yeshivas Toras Emes Chabad). He studied mathematics, physics, and chemistry at the Hebrew University, in addition to rabbinical studies at Yeshivas Tomchei Temimim in Lod and with Rabbis Dov Ber Eliezrov and Shmaryahu Noach Sasonkin. Following graduation, he established several experimental schools after an unsuccessful attempt to start a neo-Hassidic community in the Negev desert, and, at the age of 24, became Israel's youngest school principal. In 1965, he founded the Israel Institute for Talmudic Publications and began his monumental work on the Talmud, including translation into Hebrew, English, Russian, and various other languages. The Steinsaltz editions of the Talmud include translation from the original Aramaic and a comprehensive commentary. Steinsaltz completed his Hebrew edition of the entire Babylonian Talmud in November 2010, at which time Koren Publishers Jerusalem became the publisher of all of his works, including the Talmud. While not without criticism (such as by Jacob Neusner, 1998), the Steinsaltz edition is widely used throughout Israel, the United States, and the world. Steinsaltz's classic work on Kabbalah, The Thirteen Petalled Rose, was first published in 1980, and now appears in eight languages. In all, Steinsaltz authored some 60 books and hundreds of articles on subjects including Talmud, Jewish mysticism, Jewish philosophy, sociology, historical biography, and philosophy. Many of these works have been translated into English by his close personal friend, now deceased, Yehuda Hanegbi. His memoir-biography on the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, was published by Maggid Books (2014). Continuing his work as a teacher and spiritual mentor, Steinsaltz joined the original faculty of the nondenominational Pardes Institute of Jewish Studies in Jerusalem in 1972, along with David Hartman, Eliezer Schweid, Menachem Froman, Dov Berkovits, and others. He established Yeshivat Mekor Chaim alongside Rabbis Menachem Froman and Shagar in 1984 and Yeshivat Tekoa in 1999. He also served as president of the Shefa Middle and High Schools. He has served as scholar in residence at the Woodrow Wilson International Center for Scholars in Washington, D.C., and the Institute for Advanced Study in Princeton. His honorary degrees include doctorates from Yeshiva University, Ben Gurion University of the Negev, Bar Ilan University, Brandeis University, and Florida International University. Steinsaltz was also Rosh Yeshiva of Yeshivat Hesder Tekoa. Being a follower of Rabbi Menachem Mendel Schneerson of Chabad-Lubavitch, he went to help Jews in the Soviet Union assisting Chabad's shluchim (propagators) network. In 1995, the chief Rabbi of Russia, Adolph Shayevich gave Steinzaltz the title of Duchovny Ravin (Spiritual Rabbi), a historic Russian title which indicated that he was the spiritual mentor of Russian Jewry. In this capacity, Steinsaltz travelled to Russia and the Republics once each month from his home in Jerusalem. During his time in the former Soviet Union, he founded the Jewish University, both in Moscow and Saint Petersburg. The Jewish University is the first degree-granting institution of Jewish studies in the former Soviet Union. In 1991, on Schneersohn's advice, he changed his family name from Steinsaltz to Even-Israel. Besides Chabad, Steinsaltz was also inspired by the teachings of the Kotzker Rebbe. He was in close contact with the fifth Gerrer Rebbe, Yisroel Alter, and his brother and successor, Simcha Bunim Alter. Steinsaltz took a cautious approach to interfaith dialogues. During a visit of a delegation of Roman Catholic cardinals in Manhattan in January 2004, he said that, "You do not have to raise over-expectations of a meeting, as it doesn't signify in itself a breakthrough; however, the opportunity for cardinals and rabbis to speak face to face is valuable. It's part of a process in which we can talk to each other in a friendly way", and called for "a theological dialogue that asks the tough questions, such as whether Catholicism allows for Jews to enter eternal paradise". Steinsaltz and his wife lived in Jerusalem until his death and had three children and many grandchildren and great-grandchildren. In 2016, Steinsaltz suffered a stroke, leaving him unable to speak. His son, Rabbi Menachem ("Meni") Even-Israel, is the executive director of the Steinsaltz Center, Rabbi Steinsaltz's umbrella organization, located in the Nachlaot neighborhood of Jerusalem. Steinsaltz died in Jerusalem on 7 August 2020, from acute pneumonia, at the Shaare Tzedek Medical Center. He was hospitalized earlier in the week with a severe lung infection. He leaves behind his wife Sarah, three children and eighteen grandchildren. Head of the new Sanhedrin Steinsaltz accepted the position as Nasi (President) of the 2004 attempt to revive the Sanhedrin. In 2008, he resigned from this position due to differences of opinion. As an author Steinsaltz was a prolific author and commentator, having written numerous books on Jewish knowledge, tradition and culture, and produced original commentaries on the entirety of Jewish canon: Tanakh (Torah, Prophets, and Writings), the Babylonian Talmud, the Mishna, the Mishneh Torah, and Tanya. His published works include: Biblical Images (1984) The Candle of God (1998) A Dear Son to Me (2011) The Essential Talmud (1976) A Guide to Jewish Prayer (2000) The Passover Haggadah (1983) In the Beginning (1992) My Rebbe (2014) The Tales of Rabbi Nachman of Bratslav (1993) On Being Free (1995) The Miracle of the Seventh Day (2003) Simple Words (1999) The Strife of the Spirit (1988) A Reference Guide to The Talmud (2012) Talmudic Images (1997) Learning from the Tanya (2005) Opening the Tanya (2003) Understanding the Tanya (2007) Teshuvah (1982) The Longer Shorter Way (1988) The Seven Lights: On the Major Jewish Festivals (2000) The Sustaining Utterance (1989) The Thirteen Petalled Rose (1980) We Jews (2005) The Woman of Valor (1994) As a speaker Steinsaltz was invited to speak at the Aspen Institute for Humanistic Studies at Yale University in 1979. Prior to his stroke, he gave evening seminars in Jerusalem, which, according to Newsweek, usually lasted until 2:00 in the morning and attracted prominent politicians, such as the former Prime Minister Levi Eshkol and former Finance Minister Pinchas Sapir. Awards and critical reception On 21 April 1988, Steinsaltz received the Israel Prize for Jewish Studies. On 9 February 2012, Steinsaltz was honored by Israeli President Shimon Peres with Israel's first President's Prize alongside Zubin Mehta, Uri Slonim, Henry Kissinger, Judy Feld Carr, and the Rashi Foundation.[15] Steinsaltz was presented with this award for his contribution to the study of Talmud, making it more accessible to Jews worldwide. Steinsaltz was also presented with the 2012 National Jewish Book Award in the category of Modern Jewish Thought & Experience by the Jewish Book Council for his commentary, translation, and notes in the Koren Babylonian Talmud. The Modern Jewish Thought & Experience award was awarded on 15 January 2013 in memory of Joy Ungerleider Mayerson by the Dorot Foundation. On 22 May 2017, Jerusalem Mayor Nir Barkat visited Steinsaltz at his home to present him with the Yakir Yerushalayim ("Worthy Citizen of Jerusalem") medal. This medal of achievement was awarded to Steinsaltz for his writing and translating work. On 10 June 2018, Steinsaltz was honored at a Gala Dinner at the Orient Hotel in Jerusalem for his pedagogical achievements throughout a lifetime dedicated to Jewish education. A limited-edition version of "The Steinsaltz Humash” was presented to the attendees of this event. Public reception Academic criticism Jacob Neusner's How Adin Steinsaltz Misrepresents the Talmud. Four False Propositions from his "Reference Guide" (1998) displays strong disagreement. In what was an overall favorable review, Dr. Jeremy Brown notes that the Koren Talmud Bavli contains some inaccurate scientific information, such as identifying Ursa Major as a star and describing polycythemia vera as a disease causing excessive bleeding from the gums and from ordinary cuts. Aharon Feldman penned a lengthy critical review of the Steinsaltz Talmud contending that the work "is marred by an extraordinary number of inaccuracies stemming primarily from misreadings of the sources; it fails to explain those difficult passages which the reader would expect it to explain; and it confuses him with notes which are often irrelevant, incomprehensible, and contradictory." Feldman says he fears that, "An intelligent student utilizing the Steinsaltz Talmud as his personal instructor might in fact conclude that Talmud in general is not supposed to make sense." Furthermore, writes Feldman, the Steinsaltz Talmud gives off the impression that the Talmud is "intellectually flabby, inconsistent, and often trivial." Haredi reaction and ban Publication of the Steinsaltz Hebrew translation of the Talmud in the 1960s received endorsements from prominent rabbis including Moshe Feinstein and Ovadia Yosef. However, in 1989, when the English version appeared, Steinsaltz faced a fierce backlash from many leading rabbis in Israel such as Elazar Shach, Yosef Shalom Eliashiv, Eliezer Waldenberg, Nissim Karelitz, Chaim Pinchas Scheinberg and Shmuel Wosner who harshly condemned his work and other publications. Branding him a heretic, Shach was at the forefront of a campaign which banned all his works, believing that his literary and psychological explanations of biblical characters and events rendered them heretical. He also slated his translation of the Talmud, describing it as being written in the style of a secular book causing "any trace of holiness and faith to vanish." Waldenberg wrote that he was shocked to see the way in which Steinsaltz described the Patriarchs and Talmudic sages, writing that the works had the power to "poison the souls" of those who read them. Striking a more conciliatory tone in the controversy however were the Gerer Hasidim who praised his works and commended him on his willingness to amend various passages "which could have been misconstrued." After the Jerusalem-based Edah Charedis limited the ban to three books, Steinsaltz publicly apologised for his error and offered to refund anyone who had bought the books. The ban nevertheless caused thousands of schools and individuals to discard the Steinsaltz Talmud, with Rabbi Avigdor Nebenzahl ordering all copies to be placed in genizah. This led to more liberal Jewish movements placing adverts in the press asking for the edition to be donated to their institutions instead. For his part, Steinsaltz countered that much of the criticism he faced was rooted in opposition to the Chabad-Lubavitch community he was affiliated with. Praise While certain members of the Haredi community may have opposition to Steinsaltz's works, other Jewish leaders, rabbis, and authors have spoken or written about their appreciation for Steinsaltz's unique educational approach. Rabbi John Rosove of Temple Israel of Hollywood featured "Opening The Tanya", "Learning the Tanya", and "Understanding the Tanya" on his list of the top ten recommended Jewish books. These volumes are written by Rabbi Shneur Zalman of Liadi, the founder of the Chabad Lubavitch movement, and include commentary by Steinsaltz. Through reading the Tanya, readers can explore all aspects of the central text of Chabad movement. Rabbi Elie Kaunfer, a rosh yeshiva and the CEO of Mechon Hadar Yeshiva, discussed his gratitude for Steinsaltz's Global Day of Jewish Learning and the opportunity created by this online platform for learning and creating a deeper connection to Torah, other Jewish text, and Jews worldwide. Rabbi Pinchas Allouche, who studied under Steinsaltz, notes that Steinsaltz "is a world scholar" who "revolutionized the Jewish landscape" through his commentary, other writings, and educational organizations. In 1988, secular Israeli historian Zeev Katz compared Steinsaltz's importance to that of Rashi and Maimonides, two Jewish scholars of medieval times. In addition, Ilana Kurshan, an American-Israeli author, wrote that Steinsaltz's ability to bring "the historical world of the Talmudic stages to life" created an enjoyable Jewish learning experience for her when she was intensely studying Talmud.

A. E. Housman

Alfred Edward Housman (; 26 March 1859 – 30 April 1936) was an English classical scholar and poet. His cycle of poems, A Shropshire Lad, wistfully evokes the constraints and limited choices of youth in the English countryside. The simplicity and distinctive imagery of the writing appealed strongly to Edwardian taste, and to many early 20th-century English composers, both before and after the First World War. Through their song-settings, the poems became closely associated with that era, and with Shropshire itself. Housman was one of the foremost classicists of his age and has been ranked as one of the greatest scholars at any time. He established his reputation publishing as a private scholar at first and, on the strength and quality of his work, was appointed Professor of Latin at University College London and then at the University of Cambridge. His editions of Juvenal, Manilius and Lucan are still considered authoritative. Early life The eldest of seven children, Housman was born at Valley House in Fockbury, a hamlet on the outskirts of Bromsgrove in Worcestershire, to Sarah Jane (née Williams, married 17 June 1858 in Woodchester, Gloucester) and Edward Housman (whose family came from Lancaster), and was baptised on 24 April 1859 at Christ Church, in Catshill. His mother died on his twelfth birthday, and his father, a country solicitor, then married an elder cousin, Lucy, in 1873. Two of his siblings became prominent writers, sister Clemence Housman and brother Laurence Housman. Housman was educated at King Edward's School in Birmingham and later Bromsgrove School, where he revealed his academic promise and won prizes for his poems. In 1877 he won an open scholarship to St John's College, Oxford, and went there to study classics. Although introverted by nature, Housman formed strong friendships with two roommates, Moses John Jackson (1858 – 14 January 1923) and A. W. Pollard. Though Housman obtained a first in classical Moderations in 1879, his dedication to textual analysis led him to neglect the ancient history and philosophy that formed part of the Greats curriculum. Accordingly, he failed his Finals and had to return humiliated in Michaelmas term to resit the exam and at least gain a lower-level pass degree. Though some attribute Housman's unexpected performance in his exams directly to his unrequited feelings for Jackson, most biographers adduce more obvious causes. Housman was indifferent to philosophy and overconfident in his exceptional gifts, and he spent too much time with his friends. He may also have been distracted by news of his father's desperate illness. After Oxford, Jackson went to work as a clerk in the Patent Office in London and arranged a job there for Housman too. The two shared a flat with Jackson's brother Adalbert until 1885, when Housman moved to lodgings of his own, probably after Jackson responded to a declaration of love by telling Housman that he could not reciprocate his feelings. Two years later, Jackson moved to India, placing more distance between himself and Housman. When he returned briefly to England in 1889, to marry, Housman was not invited to the wedding and knew nothing about it until the couple had left the country. Adalbert Jackson died in 1892 and Housman commemorated him in a poem published as "XLII – A.J.J." of More Poems (1936). Meanwhile, Housman pursued his classical studies independently, and published scholarly articles on Horace, Propertius, Ovid, Aeschylus, Euripides and Sophocles. He also completed an edition of Propertius, which however was rejected by both Oxford University Press and Macmillan in 1885, and was destroyed after his death. He gradually acquired such a high reputation that in 1892 he was offered and accepted the professorship of Latin at University College London (UCL). When, during his tenure, an immensely rare Coverdale Bible of 1535 was discovered in the UCL library and presented to the Library Committee, Housman (who had become an atheist while at Oxford) remarked that it would be better to sell it to "buy some really useful books with the proceeds". Later life Although Housman's early work and his responsibilities as a professor included both Latin and Greek, he began to specialise in Latin poetry. When asked later why he had stopped writing about Greek verse, he responded, "I found that I could not attain to excellence in both." In 1911 he took the Kennedy Professorship of Latin at Trinity College, Cambridge, where he remained for the rest of his life. Between 1903 and 1930 Housman published his critical edition of Manilius's Astronomicon in five volumes. He also edited Juvenal (1905) and Lucan (1926). G. P. Goold, Classics Professor at University College, wrote of his predecessor's accomplishments that "the legacy of Housman's scholarship is a thing of permanent value; and that value consists less in obvious results, the establishment of general propositions about Latin and the removal of scribal mistakes, than in the shining example he provides of a wonderful mind at work … He was and may remain the last great textual critic". Many colleagues were unnerved by Housman's scathing attacks on those he thought guilty of shoddy scholarship. In his paper "The Application of Thought to Textual Criticism" (1921) he wrote: "A textual critic engaged upon his business is not at all like Newton investigating the motion of the planets: he is much more like a dog hunting for fleas". He declared many of his contemporary scholars to be stupid, lazy, vain, or all three, saying: "Knowledge is good, method is good, but one thing beyond all others is necessary; and that is to have a head, not a pumpkin, on your shoulders, and brains, not pudding, in your head". His younger colleague A. S. F. Gow quoted examples of these attacks, noting that they "were often savage in the extreme". Gow also related how Housman intimidated students, sometimes reducing the women to tears. According to Gow, Housman could never remember the names of female students, maintaining that "had he burdened his memory by the distinction between Miss Jones and Miss Robinson, he might have forgotten that between the second and fourth declension". Among the more notable students at his Cambridge lectures was Enoch Powell, one of whose own Classical emendations was later complimented by Housman. In his private life Housman enjoyed country walks, gastronomy, air travel and making frequent visits to France, where he read "books which were banned in Britain as pornographic" but he struck A. C. Benson, a fellow don, as being "descended from a long line of maiden aunts". His feelings about his poetry were ambivalent and he certainly treated it as secondary to his scholarship. He did not speak in public about his poems until 1933, when he gave a lecture "The Name and Nature of Poetry", arguing there that poetry should appeal to emotions rather than to the intellect. Housman died, aged 77, in Cambridge. His ashes are buried just outside St Laurence's Church, Ludlow, Shropshire. A cherry tree was planted there in his memory (see A Shropshire Lad II) and replaced by the Housman Society in 2003 with a new cherry tree nearby. Poetry A Shropshire Lad During his years in London, Housman completed A Shropshire Lad, a cycle of 63 poems. After one publisher had turned it down, he helped subsidise its publication in 1896. At first selling slowly, it rapidly became a lasting success. Its appeal to English musicians had helped to make it widely known before World War I, when its themes struck a powerful chord with English readers. The book has been in print continuously since May 1896. The poems are marked by pessimism and preoccupation with death, without religious consolation (Housman had become an atheist while still an undergraduate). Housman wrote many of them while living in Highgate, London, before ever visiting Shropshire, which he presented in an idealised pastoral light as his 'land of lost content'. Housman himself acknowledged that "No doubt I have been unconsciously influenced by the Greeks and Latins, but [the] chief sources of which I am conscious are Shakespeare's songs, the Scottish Border ballads, and Heine". Later collections Housman began collecting a new set of poems after the First World War. His early work was an influence on many British poets who became famous by their writing about the war, and he wrote several poems as occasional verse to commemorate the war dead. This included his Epitaph on an Army of Mercenaries, honouring the British Expeditionary Force, an elite but small force of professional soldiers sent to Belgium at the start of the war. In the early 1920s, when Moses Jackson was dying in Canada, Housman wanted to assemble his best unpublished poems so that Jackson could read them before his death. These later poems, mostly written before 1910, show a greater variety of subject and form than those in A Shropshire Lad but lack its consistency. He published his new collection as Last Poems (1922), feeling that his inspiration was exhausted and that he should not publish more in his lifetime. After Housman's death in 1936, his brother, Laurence published further poems in More Poems (1936), A. E .H.: Some Poems, Some Letters and a Personal Memoir by his Brother (1937), and Collected Poems (1939). A. E. H. includes humorous verse such as a parody of Longfellow's poem Excelsior. Housman also wrote a parodic Fragment of a Greek Tragedy, in English, published posthumously with humorous poems under the title Unkind to Unicorns. John Sparrow quoted a letter written late in Housman's life that described the genesis of his poems: Sparrow himself adds, "How difficult it is to achieve a satisfactory analysis may be judged by considering the last poem in A Shropshire Lad. Of its four stanzas, Housman tells us that two were 'given' him ready made; one was coaxed forth from his subconsciousness an hour or two later; the remaining one took months of conscious composition. No one can tell for certain which was which." De Amicitia (Of Friendship) In 1942 Laurence Housman also deposited an essay entitled "A. E. Housman's 'De Amicitia'" in the British Library, with the proviso that it was not to be published for 25 years. The essay discussed A. E. Housman's homosexuality and his love for Moses Jackson. Despite the conservative nature of the times and his own caution in public life, Housman was quite open in his poetry, and especially in A Shropshire Lad, about his deeper sympathies. Poem XXX of that sequence, for instance, speaks of how "Fear contended with desire": "Others, I am not the first, / Have willed more mischief than they durst". In More Poems, he buries his love for Moses Jackson in the very act of commemorating it, as his feelings of love are not reciprocated and must be carried unfulfilled to the grave: His poem "Oh who is that young sinner with the handcuffs on his wrists?", written after the trial of Oscar Wilde, addressed more general attitudes towards homosexuals. In the poem the prisoner is suffering "for the colour of his hair", a natural quality that, in a coded reference to homosexuality, is reviled as "nameless and abominable" (recalling the legal phrase peccatum illud horribile, inter Christianos non nominandum, "that horrible sin, not to be named amongst Christians"). Housman song settings Housman's poetry, especially A Shropshire Lad, was set to music by many British, and in particular English, composers in the first half of the 20th century. The national, pastoral and traditional elements of his style resonated with similar trends in English music. In 1904 the cycle A Shropshire Lad was set by Arthur Somervell, who in 1898 had begun to develop the concept of the English song-cycle in his version of Tennyson's "Maud". Stephen Banfield believes it was acquaintance with Somervell's cycle that led other composers to set Housman: Ralph Vaughan Williams is likely to have attended the first performance at the Aeolian Hall on 3 February 1905. His well-known cycle of six songs On Wenlock Edge, for string quartet, tenor and piano, was published in 1909. Between 1909 and 1911 George Butterworth produced settings in two collections, Six Songs from A Shropshire Lad and Bredon Hill and Other Songs. He also wrote the orchestral tone poem A Shropshire Lad, first performed at Leeds Festival in 1912. Ivor Gurney was another composer who made renowned settings of Housman's poems. Towards the end of World War I he was working on his cycle Ludlow and Teme, for voice and string quartet (published in 1919), and went on to compose the eight-song cycle The Western Playland in 1921. One more who set Housman songs during this period was John Ireland in the song cycle, The Land of Lost Content (192021). Even composers not directly associated with the 'pastoral' tradition, such as Arnold Bax, Lennox Berkeley and Arthur Bliss, were attracted to Housman's poetry. A 1976 catalogue listed 400 musical settings of Housman's poems. As of 2020, Lieder Net Archive records 615 settings of 187 texts. Commemorations The earliest commemoration of Housman was in the chapel of Trinity College in Cambridge, where there is a memorial brass on the south wall. The Latin inscription was composed by his colleague there, A. S. F. Gow, who was also the author of a biographical and bibliographical sketch published immediately following his death. Translated into English, the memorial reads: From 1947, University College London's academic common room was dedicated to his memory as the Housman Room. Blue plaques followed later elsewhere, the first being on Byron Cottage in Highgate in 1969, recording the fact that A Shropshire Lad was written there. More followed, placed on his Worcestershire birthplace, his homes and school in Bromsgrove. The latter were encouraged by the Housman Society, which was founded in the town in 1973. Another initiative was the statue in Bromsgrove High Street, showing the poet striding with walking stick in hand. The work of local sculptor Kenneth Potts, it was unveiled on 22 March 1985. The blue plaques in Worcestershire were set up on the centenary of A Shropshire Lad in 1996. In September of the same year a memorial window lozenge was dedicated at Poets' Corner in Westminster Abbey The following year saw the première of Tom Stoppard's play The Invention of Love, whose subject is the relationship between Housman and Moses Jackson. As the 150th anniversary of his birth approached, London University inaugurated its Housman lectures on classical subjects in 2005, initially given every second year then annually after 2011. The anniversary itself in 2009 saw the publication of a new edition of A Shropshire Lad, including pictures from across Shropshire taken by local photographer Gareth Thomas. Among other events, there were performances of Vaughan Williams' On Wenlock Edge and Gurney's Ludlow and Teme at St Laurence's Church in Ludlow.

Attribution of recent climate change

Attribution of recent climate change is the effort to scientifically ascertain mechanisms responsible for recent global warming and related climate changes on Earth. The effort has focused on changes observed during the period of instrumental temperature record, particularly in the last 50 years. This is the period when human activity has grown fastest and observations of the atmosphere above the surface have become available. According to the Intergovernmental Panel on Climate Change (IPCC), it is "extremely likely" that human influence was the dominant cause of global warming between 1951 and 2010. Likely human contribution is 93%–123% of the observed 1951–2010 temperature change. Some of the main human activities that contribute to global warming are: increasing atmospheric concentrations of greenhouse gases, for a warming effect global changes to land surface, such as deforestation, for a warming effect increasing atmospheric concentrations of aerosols, mainly for a cooling effect In addition to human activities, some natural mechanisms can also cause climate change, including for example, climate oscillations, changes in solar activity, and volcanic activity. Multiple lines of evidence support attribution of recent climate change to human activities: A physical understanding of the climate system: greenhouse gas concentrations have increased and their warming properties are well-established. Historical estimates of past climate changes suggest that the recent changes in global surface temperature are unusual. Computer-based climate models are unable to replicate the observed warming unless human greenhouse gas emissions are included. Natural forces alone (such as solar and volcanic activity) cannot explain the observed warming. The IPCC's attribution of recent global warming to human activities reflects the view of the scientific community, and is also supported by 196 other scientific organizations worldwide. () Background Factors affecting Earth's climate can be broken down into forcings, feedbacks and internal variations. A forcing is something that is imposed externally on the climate system. External forcings include natural phenomena such as volcanic eruptions and variations in the sun's output. Human activities can also impose forcings, for example, through changing the composition of Earth's atmosphere. Radiative forcing is a measure of how various factors alter the energy balance of planet Earth. A positive radiative forcing will lead towards a warming of the surface and, over time, the climate system. Between the start of the Industrial Revolution in 1750, and the year 2005, the increase in the atmospheric concentration of carbon dioxide (chemical formula: ) led to a positive radiative forcing, averaged over the Earth's surface area, of about 1.66 watts per square metre (abbreviated W m−2). Climate feedbacks can either amplify or dampen the response of the climate to a given forcing. There are many feedback mechanisms in the climate system that can either amplify (a positive feedback) or diminish (a negative feedback) the effects of a change in climate forcing. The climate system will vary in response to changes in forcings. The climate system will show internal variability both in the presence and absence of forcings imposed on it, (see images opposite). This internal variability is a result of complex interactions between components of the climate system, such as the coupling between the atmosphere and ocean (see also the later section on Internal climate variability and global warming). An example of internal variability is the El Niño–Southern Oscillation. Detection vs. attribution Detection and attribution of climate signals, as well as its common-sense meaning, has a more precise definition within the climate change literature, as expressed by the IPCC. Detection of a climate signal does not always imply significant attribution. The IPCC's Fourth Assessment Report says "it is extremely likely that human activities have exerted a substantial net warming influence on climate since 1750," where "extremely likely" indicates a probability greater than 95%. Detection of a signal requires demonstrating that an observed change is statistically significantly different from that which can be explained by natural internal variability. Attribution requires demonstrating that a signal is: unlikely to be due entirely to internal variability; consistent with the estimated responses to the given combination of anthropogenic and natural forcing not consistent with alternative, physically plausible explanations of recent climate change that exclude important elements of the given combination of forcings. Key attributions Greenhouse gases is absorbed and emitted naturally as part of the carbon cycle, through animal and plant respiration, volcanic eruptions, and ocean-atmosphere exchange. Human activities, such as the burning of fossil fuels and changes in land use (see below), release large amounts of carbon to the atmosphere, causing concentrations in the atmosphere to rise. The high-accuracy measurements of atmospheric concentration, initiated by Charles David Keeling in 1958, constitute the master time series documenting the changing composition of the atmosphere. These data have iconic status in climate change science as evidence of the effect of human activities on the chemical composition of the global atmosphere. In May 2019, the concentration of in the atmosphere reached 415 ppm. The last time when it reached this level was 2.6–5.3 million years ago. Without human intervention, it would be 280 ppm. Along with , methane and to a lesser extent nitrous oxide are also major forcing contributors to the greenhouse effect. The Kyoto Protocol lists these together with hydrofluorocarbon (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are entirely artificial gases, as contributors to radiative forcing. The chart at right attributes anthropogenic greenhouse gas emissions to eight main economic sectors, of which the largest contributors are power stations (many of which burn coal or other fossil fuels), industrial processes, transportation fuels (generally fossil fuels), and agricultural by-products (mainly methane from enteric fermentation and nitrous oxide from fertilizer use). Water vapor Water vapor is the most abundant greenhouse gas and is the largest contributor to the natural greenhouse effect, despite having a short atmospheric lifetime (about 10 days). Some human activities can influence local water vapor levels. However, on a global scale, the concentration of water vapor is controlled by temperature, which influences overall rates of evaporation and precipitation. Therefore, the global concentration of water vapor is not substantially affected by direct human emissions. Land use Climate change is attributed to land use for two main reasons. Between 1750 and 2007, about two-thirds of anthropogenic emissions were produced from burning fossil fuels, and about one-third of emissions from changes in land use, primarily deforestation. Deforestation both reduces the amount of carbon dioxide absorbed by deforested regions and releases greenhouse gases directly, together with aerosols, through biomass burning that frequently accompanies it. Some of the causes of climate change are, generally, not connected with it directly in the media coverage. For example, the harm done by humans to the populations of Elephants and Monkeys contributes to deforestation therefore to climate change. A second reason that climate change has been attributed to land use is that the terrestrial albedo is often altered by use, which leads to radiative forcing. This effect is more significant locally than globally. Livestock and land use Worldwide, livestock production occupies 70% of all land used for agriculture, or 30% of the ice-free land surface of the Earth. More than 18% of anthropogenic greenhouse gas emissions are attributed to livestock and livestock-related activities such as deforestation and increasingly fuel-intensive farming practices. Specific attributions to the livestock sector include: 9% of global anthropogenic carbon dioxide emissions 35–40% of global anthropogenic methane emissions (chiefly due to enteric fermentation and manure) 64% of global anthropogenic nitrous oxide emissions, chiefly due to fertilizer use. Aerosols With virtual certainty, scientific consensus has attributed various forms of climate change, chiefly cooling effects, to aerosols, which are small particles or droplets suspended in the atmosphere. Key sources to which anthropogenic aerosols are attributed include: biomass burning such as slash-and-burn deforestation. Aerosols produced are primarily black carbon. industrial air pollution, which produces soot and airborne sulfates, nitrates, and ammonium dust produced by land use effects such as desertification Attribution of 20th-century climate change Over the past 150 years human activities have released increasing quantities of greenhouse gases into the atmosphere. This has led to increases in mean global temperature, or global warming. Other human effects are relevant—for example, sulphate aerosols are believed to have a cooling effect. Natural factors also contribute. According to the historical temperature record of the last century, the Earth's near-surface air temperature has risen around 0.74 ± 0.18 °Celsius (1.3 ± 0.32 °Fahrenheit). A historically important question in climate change research has regarded the relative importance of human activity and non-anthropogenic causes during the period of instrumental record. In the 1995 Second Assessment Report (SAR), the IPCC made the widely quoted statement that "The balance of evidence suggests a discernible human influence on global climate". The phrase "balance of evidence" suggested the (English) common-law standard of proof required in civil as opposed to criminal courts: not as high as "beyond reasonable doubt". In 2001 the Third Assessment Report (TAR) refined this, saying "There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities". The 2007 Fourth Assessment Report (AR4) strengthened this finding: "Anthropogenic warming of the climate system is widespread and can be detected in temperature observations taken at the surface, in the free atmosphere and in the oceans. Evidence of the effect of external influences, both anthropogenic and natural, on the climate system has continued to accumulate since the TAR." Other findings of the IPCC Fourth Assessment Report include: "It is extremely unlikely (<5%) that the global pattern of warming during the past half century can be explained without external forcing (i.e., it is inconsistent with being the result of internal variability), and very unlikely that it is due to known natural external causes alone. The warming occurred in both the ocean and the atmosphere and took place at a time when natural external forcing factors would likely have produced cooling." "From new estimates of the combined anthropogenic forcing due to greenhouse gases, aerosols, and land surface changes, it is extremely likely (>95%) that human activities have exerted a substantial net warming influence on climate since 1750." "It is virtually certain that anthropogenic aerosols produce a net negative radiative forcing (cooling influence) with a greater magnitude in the Northern Hemisphere than in the Southern Hemisphere." Over the past five decades there has been a global warming of approximately 0.65 °C (1.17 °F) at the Earth's surface (see historical temperature record). Among the possible factors that could produce changes in global mean temperature are internal variability of the climate system, external forcing, an increase in concentration of greenhouse gases, or any combination of these. Current studies indicate that the increase in greenhouse gases, most notably , is mostly responsible for the observed warming. Evidence for this conclusion includes: Estimates of internal variability from climate models, and reconstructions of past temperatures, indicate that the warming is unlikely to be entirely natural. Climate models forced by natural factors and increased greenhouse gases and aerosols reproduce the observed global temperature changes; those forced by natural factors alone do not. "Fingerprint" methods (see below) indicate that the pattern of change is closer to that expected from greenhouse gas-forced change than from natural change. The plateau in warming from the 1940s to 1960s can be attributed largely to sulphate aerosol cooling. Details on attribution Recent scientific assessments find that most of the warming of the Earth's surface over the past 50 years has been caused by human activities (see also the section on scientific literature and opinion). This conclusion rests on multiple lines of evidence. Like the warming "signal" that has gradually emerged from the "noise" of natural climate variability, the scientific evidence for a human influence on global climate has accumulated over the past several decades, from many hundreds of studies. No single study is a "smoking gun." Nor has any single study or combination of studies undermined the large body of evidence supporting the conclusion that human activity is the primary driver of recent warming. The first line of evidence is based on a physical understanding of how greenhouse gases trap heat, how the climate system responds to increases in greenhouse gases, and how other human and natural factors influence climate. The second line of evidence is from indirect estimates of climate changes over the last 1,000 to 2,000 years. These records are obtained from living things and their remains (like tree rings and corals) and from physical quantities (like the ratio between lighter and heavier isotopes of oxygen in ice cores), which change in measurable ways as climate changes. The lesson from these data is that global surface temperatures over the last several decades are clearly unusual, in that they were higher than at any time during at least the past 400 years. For the Northern Hemisphere, the recent temperature rise is clearly unusual in at least the last 1,000 years (see graph opposite). The third line of evidence is based on the broad, qualitative consistency between observed changes in climate and the computer model simulations of how climate would be expected to change in response to human activities. For example, when climate models are run with historical increases in greenhouse gases, they show gradual warming of the Earth and ocean surface, increases in ocean heat content and the temperature of the lower atmosphere, a rise in global sea level, retreat of sea ice and snow cover, cooling of the stratosphere, an increase in the amount of atmospheric water vapor, and changes in large-scale precipitation and pressure patterns. These and other aspects of modelled climate change are in agreement with observations. "Fingerprint" studies Finally, there is extensive statistical evidence from so-called "fingerprint" studies. Each factor that affects climate produces a unique pattern of climate response, much as each person has a unique fingerprint. Fingerprint studies exploit these unique signatures, and allow detailed comparisons of modelled and observed climate change patterns. Scientists rely on such studies to attribute observed changes in climate to a particular cause or set of causes. In the real world, the climate changes that have occurred since the start of the Industrial Revolution are due to a complex mixture of human and natural causes. The importance of each individual influence in this mixture changes over time. Of course, there are not multiple Earths, which would allow an experimenter to change one factor at a time on each Earth, thus helping to isolate different fingerprints. Therefore, climate models are used to study how individual factors affect climate. For example, a single factor (like greenhouse gases) or a set of factors can be varied, and the response of the modelled climate system to these individual or combined changes can thus be studied. These projections have been confirmed by observations (shown above). For example, when climate model simulations of the last century include all of the major influences on climate, both human-induced and natural, they can reproduce many important features of observed climate change patterns. When human influences are removed from the model experiments, results suggest that the surface of the Earth would actually have cooled slightly over the last 50 years. The clear message from fingerprint studies is that the observed warming over the last half-century cannot be explained by natural factors, and is instead caused primarily by human factors. Another fingerprint of human effects on climate has been identified by looking at a slice through the layers of the atmosphere, and studying the pattern of temperature changes from the surface up through the stratosphere (see the section on solar activity). The earliest fingerprint work focused on changes in surface and atmospheric temperature. Scientists then applied fingerprint methods to a whole range of climate variables, identifying human-caused climate signals in the heat content of the oceans, the height of the tropopause (the boundary between the troposphere and stratosphere, which has shifted upward by hundreds of feet in recent decades), the geographical patterns of precipitation, drought, surface pressure, and the runoff from major river basins. Studies published after the appearance of the IPCC Fourth Assessment Report in 2007 have also found human fingerprints in the increased levels of atmospheric moisture (both close to the surface and over the full extent of the atmosphere), in the decline of Arctic sea ice extent, and in the patterns of changes in Arctic and Antarctic surface temperatures. The message from this entire body of work is that the climate system is telling a consistent story of increasingly dominant human influence – the changes in temperature, ice extent, moisture, and circulation patterns fit together in a physically consistent way, like pieces in a complex puzzle. Increasingly, this type of fingerprint work is shifting its emphasis. As noted, clear and compelling scientific evidence supports the case for a pronounced human influence on global climate. Much of the recent attention is now on climate changes at continental and regional scales, and on variables that can have large impacts on societies. For example, scientists have established causal links between human activities and the changes in snowpack, maximum and minimum (diurnal) temperature, and the seasonal timing of runoff over mountainous regions of the western United States. Human activity is likely to have made a substantial contribution to ocean surface temperature changes in hurricane formation regions. Researchers are also looking beyond the physical climate system, and are beginning to tie changes in the distribution and seasonal behaviour of plant and animal species to human-caused changes in temperature and precipitation. For over a decade, one aspect of the climate change story seemed to show a significant difference between models and observations. In the tropics, all models predicted that with a rise in greenhouse gases, the troposphere would be expected to warm more rapidly than the surface. Observations from weather balloons, satellites, and surface thermometers seemed to show the opposite behaviour (more rapid warming of the surface than the troposphere). This issue was a stumbling block in understanding the causes of climate change. It is now largely resolved. Research showed that there were large uncertainties in the satellite and weather balloon data. When uncertainties in models and observations are properly accounted for, newer observational data sets (with better treatment of known problems) are in agreement with climate model results. This does not mean, however, that all remaining differences between models and observations have been resolved. The observed changes in some climate variables, such as Arctic sea ice, some aspects of precipitation, and patterns of surface pressure, appear to be proceeding much more rapidly than models have projected. The reasons for these differences are not well understood. Nevertheless, the bottom-line conclusion from climate fingerprinting is that most of the observed changes studied to date are consistent with each other, and are also consistent with our scientific understanding of how the climate system would be expected to respond to the increase in heat-trapping gases resulting from human activities. Extreme weather events Scientific literature and opinion There are a number of examples of published and informal support for the consensus view. As mentioned earlier, the IPCC has concluded that most of the observed increase in globally averaged temperatures since the mid-20th century is "very likely" due to human activities. The IPCC's conclusions are consistent with those of several reports produced by the US National Research Council. A report published in 2009 by the U.S. Global Change Research Program concluded that "[global] warming is unequivocal and primarily human-induced." A number of scientific organizations have issued statements that support the consensus view: A 2004 essay in Science surveyed 928 abstracts related to climate change, and concluded that most journal reports accepted the consensus. a joint statement made in 2005 by the national science academies of the G8, and Brazil, China and India; a joint statement made in 2008 by the Network of African Science Academies. A 2010 paper in the Proceedings of the National Academy of Sciences found that among a pool of roughly 1,000 researchers who work directly on climate issues and publish the most frequently on the subject, 97% agree that anthropogenic climate change is happening. A 2011 paper from George Mason University published in the International Journal of Public Opinion Research, "The Structure of Scientific Opinion on Climate Change," collected the opinions of scientists in the earth, space, atmospheric, oceanic or hydrological sciences. The 489 survey respondents—representing nearly half of all those eligible according to the survey's specific standards – work in academia, government, and industry, and are members of prominent professional organizations. The study found that 97% of the 489 scientists surveyed agreed that global temperatures have risen over the past century. Moreover, 84% agreed that "human-induced greenhouse warming" is now occurring." Only 5% disagreed with the idea that human activity is a significant cause of global warming. Detection and attribution studies The IPCC Fourth Assessment Report (2007), concluded that attribution was possible for a number of observed changes in the climate (see effects of global warming). However, attribution was found to be more difficult when assessing changes over smaller regions (less than continental scale) and over short time periods (less than 50 years). Over larger regions, averaging reduces natural variability of the climate, making detection and attribution easier. In 1996, in a paper in Nature titled "A search for human influences on the thermal structure of the atmosphere", Benjamin D. Santer et al. wrote: "The observed spatial patterns of temperature change in the free atmosphere from 1963 to 1987 are similar to those predicted by state-of-the-art climate models incorporating various combinations of changes in carbon dioxide, anthropogenic sulphate aerosol and stratospheric ozone concentrations. The degree of pattern similarity between models and observations increases through this period. It is likely that this trend is partially due to human activities, although many uncertainties remain, particularly relating to estimates of natural variability." A 2002 paper in the Journal of Geophysical Research says "Our analysis suggests that the early twentieth century warming can best be explained by a combination of warming due to increases in greenhouse gases and natural forcing, some cooling due to other anthropogenic forcings, and a substantial, but not implausible, contribution from internal variability. In the second half of the century we find that the warming is largely caused by changes in greenhouse gases, with changes in sulphates and, perhaps, volcanic aerosol offsetting approximately one third of the warming." A 2005 review of detection and attribution studies by the International Ad hoc Detection and Attribution Group found that "natural drivers such as solar variability and volcanic activity are at most partially responsible for the large-scale temperature changes observed over the past century, and that a large fraction of the warming over the last 50 yr can be attributed to greenhouse gas increases. Thus, the recent research supports and strengthens the IPCC Third Assessment Report conclusion that 'most of the global warming over the past 50 years is likely due to the increase in greenhouse gases.'" Barnett and colleagues (2005) say that the observed warming of the oceans "cannot be explained by natural internal climate variability or solar and volcanic forcing, but is well simulated by two anthropogenically forced climate models," concluding that "it is of human origin, a conclusion robust to observational sampling and model differences". Two papers in the journal Science in August 2005 resolve the problem, evident at the time of the TAR, of tropospheric temperature trends (see also the section on "fingerprint" studies) . The UAH version of the record contained errors, and there is evidence of spurious cooling trends in the radiosonde record, particularly in the tropics. See satellite temperature measurements for details; and the 2006 US CCSP report. Multiple independent reconstructions of the temperature record of the past 1000 years confirm that the late 20th century is probably the warmest period in that time (see the preceding section -details on attribution). Solar activity Solar sunspot maximum occurs when the magnetic field of the Sun collapses and reverse as part of its average 11-year solar cycle (22 years for complete North to North restoration). The role of the Sun in recent climate change has been looked at by climate scientists. Since 1978, output from the Sun has been measured by satellites significantly more accurately than was previously possible from the surface. These measurements indicate that the Sun's total solar irradiance has not increased since 1978, so the warming during the past 30 years cannot be directly attributed to an increase in total solar energy reaching the Earth (see graph above, left). In the three decades since 1978, the combination of solar and volcanic activity probably had a slight cooling influence on the climate. Climate models have been used to examine the role of the Sun in recent climate change. Models are unable to reproduce the rapid warming observed in recent decades when they only take into account variations in total solar irradiance and volcanic activity. Models are, however, able to simulate the observed 20th century changes in temperature when they include all of the most important external forcings, including human influences and natural forcings. As has already been stated, Hegerl et al. (2007) concluded that greenhouse gas forcing had "very likely" caused most of the observed global warming since the mid-20th century. In making this conclusion, Hegerl et al. (2007) allowed for the possibility that climate models had been underestimated the effect of solar forcing. The role of solar activity in climate change has also been calculated over longer time periods using "proxy" datasets, such as tree rings. Models indicate that solar and volcanic forcings can explain periods of relative warmth and cold between AD 1000 and 1900, but human-induced forcings are needed to reproduce the late-20th century warming. Another line of evidence against the sun having caused recent climate change comes from looking at how temperatures at different levels in the Earth's atmosphere have changed. Models and observations (see figure above, middle) show that greenhouse gas results in warming of the lower atmosphere at the surface (called the troposphere) but cooling of the upper atmosphere (called the stratosphere). Depletion of the ozone layer by chemical refrigerants has also resulted in a cooling effect in the stratosphere. If the Sun was responsible for observed warming, warming of the troposphere at the surface and warming at the top of the stratosphere would be expected as increase solar activity would replenish ozone and oxides of nitrogen. The stratosphere has a reverse temperature gradient than the troposphere so as the temperature of the troposphere cools with altitude, the stratosphere rises with altitude. Hadley cells are the mechanism by which equatorial generated ozone in the tropics (highest area of UV irradiance in the stratosphere) is moved poleward. Global climate models suggest that climate change may widen the Hadley cells and push the jetstream northward thereby expanding the tropics region and resulting in warmer, dryer conditions in those areas overall. Non-consensus views Habibullo Abdussamatov (2004), head of space research at St. Petersburg's Pulkovo Astronomical Observatory in Russia, has argued that the Sun is responsible for recently observed climate change. Journalists for news sources canada.com (Solomon, 2007b), National Geographic News (Ravilious, 2007), and LiveScience (Than, 2007) reported on the story of warming on Mars. In these articles, Abdussamatov was quoted. He stated that warming on Mars was evidence that global warming on Earth was being caused by changes in the Sun. Ravilious (2007) quoted two scientists who disagreed with Abdussamatov: Amato Evan, a climate scientist at the University of Wisconsin–Madison, in the US, and Colin Wilson, a planetary physicist at Oxford University in the UK. According to Wilson, "Wobbles in the orbit of Mars are the main cause of its climate change in the current era" (see also orbital forcing). Than (2007) quoted Charles Long, a climate physicist at Pacific Northwest National Laboratories in the US, who disagreed with Abdussamatov. Than (2007) pointed to the view of Benny Peiser, a social anthropologist at Liverpool John Moores University in the UK. In his newsletter, Peiser had cited a blog that had commented on warming observed on several planetary bodies in the Solar System. These included Neptune's moon Triton, Jupiter, Pluto and Mars. In an e-mail interview with Than (2007), Peiser stated that:"I think it is an intriguing coincidence that warming trends have been observed on a number of very diverse planetary bodies in our solar system, (...) Perhaps this is just a fluke."Than (2007) provided alternative explanations of why warming had occurred on Triton, Pluto, Jupiter and Mars. The US Environmental Protection Agency (US EPA, 2009) responded to public comments on climate change attribution. A number of commenters had argued that recent climate change could be attributed to changes in solar irradiance. According to the US EPA (2009), this attribution was not supported by the bulk of the scientific literature. Citing the work of the IPCC (2007), the US EPA pointed to the low contribution of solar irradiance to radiative forcing since the start of the Industrial Revolution in 1750. Over this time period (1750 to 2005), the estimated contribution of solar irradiance to radiative forcing was 5% the value of the combined radiative forcing due to increases in the atmospheric concentrations of carbon dioxide, methane and nitrous oxide (see graph opposite). Effect of cosmic rays Henrik Svensmark has suggested that the magnetic activity of the sun deflects cosmic rays, and that this may influence the generation of cloud condensation nuclei, and thereby have an effect on the climate. The website ScienceDaily reported on a 2009 study that looked at how past changes in climate have been affected by the Earth's magnetic field. Geophysicist Mads Faurschou Knudsen, who co-authored the study, stated that the study's results supported Svensmark's theory. The authors of the study also acknowledged that plays an important role in climate change. Consensus view on cosmic rays The view that cosmic rays could provide the mechanism by which changes in solar activity affect climate is not supported by the literature. Solomon et al. (2007) state:[..] the cosmic ray time series does not appear to correspond to global total cloud cover after 1991 or to global low-level cloud cover after 1994. Together with the lack of a proven physical mechanism and the plausibility of other causal factors affecting changes in cloud cover, this makes the association between galactic cosmic ray-induced changes in aerosol and cloud formation controversial Studies by Lockwood and Fröhlich (2007) and Sloan and Wolfendale (2008) found no relation between warming in recent decades and cosmic rays. Pierce and Adams (2009) used a model to simulate the effect of cosmic rays on cloud properties. They concluded that the hypothesized effect of cosmic rays was too small to explain recent climate change. Pierce and Adams (2009) noted that their findings did not rule out a possible connection between cosmic rays and climate change, and recommended further research. Erlykin et al. (2009) found that the evidence showed that connections between solar variation and climate were more likely to be mediated by direct variation of insolation rather than cosmic rays, and concluded: "Hence within our assumptions, the effect of varying solar activity, either by direct solar irradiance or by varying cosmic ray rates, must be less than 0.07 °C since 1956, i.e. less than 14% of the observed global warming." Carslaw (2009) and Pittock (2009) review the recent and historical literature in this field and continue to find that the link between cosmic rays and climate is tenuous, though they encourage continued research. US EPA (2009) commented on research by Duplissy et al. (2009):The CLOUD experiments at CERN are interesting research but do not provide conclusive evidence that cosmic rays can serve as a major source of cloud seeding. Preliminary results from the experiment (Duplissy et al., 2009) suggest that though there was some evidence of ion mediated nucleation, for most of the nucleation events observed the contribution of ion processes appeared to be minor. These experiments also showed the difficulty in maintaining sufficiently clean conditions and stable temperatures to prevent spurious aerosol bursts. There is no indication that the earlier Svensmark experiments could even have matched the controlled conditions of the CERN experiment. We find that the Svensmark results on cloud seeding have not yet been shown to be robust or sufficient to materially alter the conclusions of the assessment literature, especially given the abundance of recent literature that is skeptical of the cosmic ray-climate linkage See also Climate change adaptation Climate change denial Climate change mitigation Climate resilience Environmental effects of aviation Notes References , pp. 332–333.

Achduart

Achduart (Gaelic: Achadh Dhubhaird) is a small hamlet in Coigach, in Wester Ross in northwestern Scotland, now within the Highland council area. It is situated about 4 km southeast of the village of Achiltibuie, at the end of a minor road. A footpath continues on to the hamlet of Culnacraig, then along the coast past Ben More Coigach to Strathcanaird. Achduart has accommodation facilities for tourists, who come for its proximity to the ocean as well as its seclusion and remoteness. There is a Scottish Youth Hostels Association hostel in Acheninver, a short distance to the north. The name of Achduart comes from the Gaelic for "the field at the black headland". Achduart was part of the Estate of Coigach, Lochbroom, belonging to the Countess of Cromartie. The dominant geographical feature in the area is Cairn Conmheall, which rises to 541 metres.

Achiltibuie

Achiltibuie (; or Field of the yellow-haired boy) is a long linear village in Ross and Cromarty, Highland, on the Coigach coast of northwestern Scotland, overlooking Badentarbet Bay to the west. Loch Broom and the Summer Isles lie to the south. Located 10 miles (16 km) northwest of Ullapool as the crow flies. Achiltibuie is the central community of a series of townships and communities stretching from Culnacraig, through Badenscallie and Polglass (where the community hall, the primary school and the Piping School Cafe are located), Polbain, and Reiff to Achnahaird. History The first post office in the village opened on 28 July 1884. Smokehouse For a time the Summer Isles Smokehouse attracted visitors. In 2013 the community had hopes to re-establish the business. Hydroponicum The Hydroponicum, a facility for growing fresh fruit and vegetables indoors using hydroponics, was built in the village in the 1980s by Robert Irvine, then owner of the Summer Isles Hotel. The Hydroponicum was known for growing exotic fruit such as bananas all year round. It attracted up to 10,000 visitors a year until it was sold in 2007 to a company based in the Isle of Man. New greenhouses have since been built apart from the original hydroponicum buildings, and the new owners continue to grow fruit and vegetables for local businesses and residents. A community buyout attempt in 2011 by the Coigach Community Development Company fell through when the site's sellers pulled out. The building has now been demolished. Some of the former staff of the Hydroponicum run a small-scale activity known as The Achiltibuie Garden, situated nearby. Notable residents Tom Longstaff (1875-1964), mountaineer. Lucy Irvine (b. 1956), writer, lived very briefly in the Summer Isles Hotel with her father, who owned it and the Hydroponicum. :de:Reiner Luyken (b.1951), former foreign correspondent of the German weekly paper Die Zeit Notable recent achievements 'Coigach Community Rowing' the crew members of which coastal rowing club are all local, won the World St. Ayles Skiff Rowing Championships in July 2013 and a mixed crew from the club won the Alan Spong Trophy for 1st Mixed crew 4-oar rowing at the Thames Great River Race in September 2013. Coigach Community Rowing hand-built their two St Ayles rowing skiffs, the 'Coigach Lass' and the 'Lily~Rose' and race under the auspices of the Scottish Coastal Rowing Association, which is the governing body of St Ayles class coastal rowing around the world. Cultural connections The Roman epic movie The Eagle, based on the 1954 novel The Eagle of the Ninth by Rosemary Sutcliff, was filmed on location in Achiltibuie for a week in October 2009. The main location was Fox Point, Old Dornie. The Pictish village which was constructed at Fox Point was used on most days of the filming. Other sites included Achnahaird beach where a horse chase was filmed and Loch Lurgainn. The village and its residents featured in The Wee Mad Road (2008) by Jack and Barbara Maloney. Achiltibuie is also the setting of a humorous German book about Scotland by Reiner Luyken, Schotten dicht (2015) published by Ullstein Verlag, Berlin.

https://en.wikipedia.org/wiki/Adaptive%20expectations

Adaptive expectations

In economics, adaptive expectations is a hypothesized process by which people form their expectations about what will happen in the future based on what has happened in the past. For example, if people want to create an expectation of the inflation rate in the future, they can refer to past inflation rates to infer some consistencies and could derive a more accurate expectation the more years they consider. One simple version of adaptive expectations is stated in the following equation, where is the next year's rate of inflation that is currently expected; is this year's rate of inflation that was expected last year; and is this year's actual rate of inflation: where is between 0 and 1. This says that current expectations of future inflation reflect past expectations and an "error-adjustment" term, in which current expectations are raised (or lowered) according to the gap between actual inflation and previous expectations. The error-adjustment term, also called partial adjustment, allows for variations in inflation rates over the previous years, especially years that have abnormally high or low rates. The above term is the partial adjustment error term, this term allows for variances that occur between actual values and expected values. The importance of considering the error prevents over and under expecting values of in the above example inflation rates. The adjustment means that the expectation can tend toward the direction of the future expected value that would be closer to the actual value, this allows a prediction to be made and consideration to be added or removed so as to be accurate of the future expectation. This consideration or error term is what allows the predicted value to be adaptable, thus creating an equation that is adaptive of the expectation being inferred. The theory of adaptive expectations can be applied to all previous periods so that current inflationary expectations equal: where equals actual inflation years in the past. The adding of a time series portion to the expectation equations accounts for multiple previous years and their respective rates in forecasting like the above example of the future inflation rate. Thus, current expected inflation reflects a weighted average of all past inflation rates, where the weights get smaller and smaller as we move further in to the past. The initial previous year has the highest weighting and the subsequent years take lesser weighting the further back the equation accounts for. When an agent makes a forecasting error (as in incorrectly recording a value or mistyping), the stochastic shock will cause the agent to incorrectly forecast the price expectation level again even if the price level experiences no further shocks, since the previous expectations only ever incorporates part of their errors. The backward nature of expectation formulation and the resultant systematic errors made by agents (see cobweb model) had become unsatisfactory to economists such as John Muth, who was pivotal in the development of an alternative model of how expectations are formed, called rational expectations. The use of rational expectations have largely replaced adaptive expectations in macroeconomic theory since its assumptions rely on an optimal expectations approach which is consistent with economic theory. However, it must be stressed that confronting adaptive expectations and rational expectations aren't necessarily justified by either use, in other words, there are situations in which following the adaptive scheme is a rational response. The first use adaptive expectations hypothesis was to describe agent behavior in The Purchasing Power of Money by Irving Fisher (1911), then later used to describe models such as hyperinflation by Philip Cagan (1956). Adaptive expectations were instrumental in the consumption function (1957) and Phillips curve outlined by Milton Friedman. Friedman suggests that workers form adaptive expectations of the inflation rate, the government can easily surprise them through unexpected monetary policy changes. As agents are trapped by the money illusion, they are unable to correctly perceive price and wage dynamics, so based on Friedman's theory, unemployment can always be reduced through monetary expansions. If the government chooses to fix a low unemployment rate the result is an increasing level of inflation for an extended period of time. However, in this framework, it is clear why and how adaptive expectations are problematic. Agents are arbitrarily supposed to ignore sources of information which, otherwise, would affect their expectations. For example, government announcements are such sources. Agents are expected to modify their expectations and break with the former trends when changes in economic policy necessitate it. This is the reason why the theory of adaptive expectations is often regarded as a deviation from the rational tradition of economics.

Mexican tetra

The Mexican tetra (Astyanax mexicanus), also known as the blind cave fish, blind cave characin, and blind cave tetra, is a freshwater fish of the family Characidae of the order Characiformes. The type species of its genus, it is native to the Nearctic realm, originating in the lower Rio Grande and the Neueces and Pecos Rivers in Texas, as well as the central and eastern parts of Mexico. Growing to a maximum total length of , the Mexican tetra is of typical characin shape, with unremarkable, drab coloration. Its blind cave form, however, is notable for having no eyes or pigment; it has a pinkish-white color to its body (resembling an albino). This fish, especially the blind variant, is reasonably popular among aquarists. A. mexicanus is a peaceful species that spends most of its time in midlevel water above the rocky and sandy bottoms of pools and backwaters of creeks and rivers of its native environment. Coming from a subtropical climate, it prefers water with 6.5–8 pH, a hardness of up to 30 dGH, and a temperature range of . In the winter, some populations migrate to warmer waters. Its natural diet consists of crustaceans, insects, and annelids, although in captivity it is omnivorous. The Mexican tetra has been treated as a subspecies of A. fasciatus, but this is not widely accepted. Additionally, the blind cave form is sometimes recognized as a separate species, A. jordani, but this directly contradicts phylogenetic evidence. Blind cave form A. mexicanus is famous for its blind cave form, which is known by such names as blind cave tetra, blind tetra (leading to easy confusion with the Brazilian Stygichthys typhlops), blind cave characin and blind cavefish. Depending on the exact population, cave forms can have degenerated sight or have total loss of sight and even their eyes, due to down-regulation of the protein αA-crystallin and consequent lens cell death. The fish in the Pachón caves have lost their eyes completely whilst the fish from the Micos cave only have limited sight. Cave fish and surface fish are able to produce fertile offspring. These fish can still, however, find their way around by means of their lateral lines, which are highly sensitive to fluctuating water pressure. Blindness in A. mexicanus induces a disruption of early neuromast patterning, which further causes asymmetries in cranial bone structure. One such asymmetry is a bend in the dorsal region of their skull, which is propounded to increase water flow to the opposite side of the face, functionally enhancing sensory input and spatial mapping in the dark waters of caves. Scientists suggest that gene cystathionine beta synthase-a mutation restricts blood flow to cavefish eyes during a critical stage of growth so the eyes are covered by skin. Currently, about 30 cave populations are known, dispersed over three geographically distinct areas in a karst region of San Luis Potosí and far southern Tamaulipas, northeastern Mexico. Among the various cave population are at least three with only full cave forms (blind and without pigment), at least eleven with cave, "normal" and intermediate forms, and at least one with both cave and "normal" forms but no intermediates. Studies suggest at least two distinct genetic lineages occur among the blind populations, and the current distribution of populations arose by at least five independent invasions. Furthermore, cave populations have a very recent origin (< 20,000 years) in which blindness or reduced vision evolved convergently after surface ancestors populated several caves independently and at different times. This recent origin suggests that the phenotypic changes in cavefish populations, namely eye degeneration, arose as a result of the high fixation of genetic variants present in surface fish populations in a short period of time. The eyed and eyeless forms of A. mexicanus, being members of the same species, are closely related and can interbreed making this species an excellent model organism for examining convergent and parallel evolution, regressive evolution in cave animals, and the genetic basis of regressive traits. This, combined with the ease of maintaining the species in captivity, has made it the most studied cavefish and likely also the most studied cave organism overall. The blind and colorless cave form of A. mexicanus is sometimes recognized as a separate species, A. jordani, but this leaves the remaining A. mexicanus as a paraphyletic species and A. jordani as polyphyletic. The Cueva Chica Cave in the southern part of the Sierra del Abra system is the type locality for A. jordani. Other blind populations were initially also recognized as separate species, including antrobius described in 1946 from the Pachón Cave and hubbsi described in 1947 from the Los Sabinos Cave (both subsequently merged into jordani/mexicanus). The most divergent cave population is the one in Los Sabinos. Another cave-adapted population of Astyanax, varying from blind and depigmented to individuals showing intermediate features, is known from the Granadas Cave, part of the Balsas River drainage in Guerrero, southern Mexico, but it is a part of A. aeneus (itself sometimes included in A. mexicanus). Evolution research The surface and cave forms of the Mexican tetra have proven powerful subjects for scientists studying evolution. When the surface-dwelling ancestors of current cave populations entered the subterranean environment, the change in ecological conditions rendered their phenotype—which included many biological functions dependent on the presence of light—subject to natural selection and genetic drift. One of the most striking changes to evolve was the loss of eyes. This is referred to as a "regressive trait" because the surface fish that originally colonized caves possessed eyes. In addition to regressive traits, cave forms evolved "constructive traits". In contrast to regressive traits, the purpose or benefit of constructive traits is generally accepted. Active research focuses on the mechanisms driving the evolution of regressive traits, such as the loss of eyes, in A. mexicanus. Recent studies have produced evidence that the mechanism may be direct selection, or indirect selection through antagonistic pleiotropy, rather than genetic drift and neutral mutation, the traditionally favored hypothesis for regressive evolution. The blind form of the Mexican tetra is different from the surface-dwelling form in a number of ways, including having unpigmented skin, having a better olfactory sense by having taste buds all over its head, and by being able to store four times more energy as fat, allowing it to deal with irregular food supplies more effectively. Darwin said of sightless fish: Modern genetics has made clear that the lack of use does not, in itself, necessitate a feature's disappearance. In this context, the positive genetic benefits have to be considered, i.e., what advantages are obtained by cave-dwelling tetras by losing their eyes? Possible explanations include: Not developing eyes allows the individual more energy for growth but not egg production. However the species does use other methods to locate food and detect danger, which also consume energy that would be conserved if it had eyes or transparent eyelids. There remains less chance of accidental damage and infection, since the previously useless and exposed organ is sealed with a flap of protective skin. It is unknown why this species did not develop transparent skin or eyelids instead, as some species of reptiles did. The lack of eyes disables the "body clock", which is controlled by periods of light and dark, conserving energy. However sunlight does have minimal impact on the "body clock" in caves. Another likely explanation for the loss of its eyes is that of selective neutrality and genetic drift; in the dark environment of the cave, the eyes are neither advantageous nor disadvantageous and thus any genetic factors that might impair the eyes (or their development) can take hold with no consequence on the individual or species. Because there is no selection pressure for sight in this environment, any number of genetic abnormalities that give rise to the damage or loss of eyes could proliferate among the population with no effect on the fitness of the population. Among some creationists, the cave tetra is seen as evidence 'against' evolution. One argument claims this is an instance of "devolution"—showing an evolutionary trend of decreasing complexity. But evolution is a non-directional process, and while increased complexity is a common effect, there is no reason why evolution cannot tend towards simplicity if that makes an organism better suited to its environment. Inhibition of the HSP90 protein has a dramatic effect in the development of the blind tetra. In the aquarium The blind cave tetras seen in the aquarium trade are all based on stock collected in the Cueva Chica Cave in the southern part of the Sierra del Abra system in 1936. These were sent to an aquarium company in Texas, who soon started to distribute them to aquarists. Since then, these have been selectively bred for their troglomorphic traits. Today large numbers are bred at commercial facilities, especially in Asia. The blind cave tetra is a hardy species. Their lack of sight does not hinder their ability to get food.

Atom probe

The atom probe was introduced at the 14th Field Emission Symposium in 1967 by Erwin Wilhelm Müller and J. A. Panitz. It combined a field ion microscope with a mass spectrometer having a single particle detection capability and, for the first time, an instrument could “... determine the nature of one single atom seen on a metal surface and selected from neighboring atoms at the discretion of the observer”. Atom probes are unlike conventional optical or electron microscopes, in that the magnification effect comes from the magnification provided by a highly curved electric field, rather than by the manipulation of radiation paths. The method is destructive in nature removing ions from a sample surface in order to image and identify them, generating magnifications sufficient to observe individual atoms as they are removed from the sample surface. Through coupling of this magnification method with time of flight mass spectrometry, ions evaporated by application of electric pulses can have their mass-to-charge ratio computed. Through successive evaporation of material, layers of atoms are removed from a specimen, allowing for probing not only of the surface, but also through the material itself. Computer methods are used to rebuild a three-dimensional view of the sample, prior to it being evaporated, providing atomic scale information on the structure of a sample, as well as providing the type atomic species information. The instrument allows the three-dimensional reconstruction of up to billions of atoms from a sharp tip (corresponding to specimen volumes of 10,000-10,000,000 nm3). Overview Atom probe samples are shaped to implicitly provide a highly curved electric potential to induce the resultant magnification, as opposed to direct use of lensing, such as via magnetic lenses. Furthermore, in normal operation (as opposed to a field ionization modes) the atom probe does not utilize a secondary source to probe the sample. Rather, the sample is evaporated in a controlled manner (field evaporation) and the evaporated ions are impacted onto a detector, which is typically 10 to 100 cm away. The samples are required to have a needle geometry and are produced by similar techniques as TEM sample preparation electropolishing, or focused ion beam methods. Since 2006, commercial systems with laser pulsing have become available and this has expanded applications from metallic only specimens into semiconducting, insulating such as ceramics, and even geological materials. Preparation is done, often by hand, to manufacture a tip radius sufficient to induce a high electric field, with radii on the order of 100 nm. To conduct an atom probe experiment a very sharp needle shaped specimen is placed in an ultra high vacuum chamber. After introduction into the vacuum system, the sample is reduced to cryogenic temperatures (typically 20-100 K) and manipulated such that the needle's point is aimed towards an ion detector. A high voltage is applied to the specimen, and either a laser pulse is applied to the specimen or a voltage pulse (typically 1-2 kV) with pulse repetition rates in the hundreds of kilohertz range is applied to a counter electrode. The application of the pulse to the sample allows for individual atoms at the sample surface to be ejected as an ion from the sample surface at a known time. Typically the pulse amplitude and the high voltage on the specimen are computer controlled to encourage only one atom to ionize at a time, but multiple ionizations are possible. The delay between application of the pulse and detection of the ion(s) at the detector allow for the computation of a mass-to-charge ratio. Whilst the uncertainty in the atomic mass computed by time-of-flight methods in atom probe is sufficiently small to allow for detection of individual isotopes within a material this uncertainty may still, in some cases, confound definitive identification of atomic species. Effects such as superposition of differing ions with multiple electrons removed, or through the presence of complex species formation during evaporation may cause two or more species to have sufficiently close time-of-flights to make definitive identification impossible. History Field ion microscopy Field ion microscopy is a modification of field emission microscopy where a stream of tunneling electrons is emitted from the apex of a sharp needle-like tip cathode when subjected to a sufficiently high electric field (~3-6 V/nm). The needle is oriented towards a phosphor screen to create a projected image of the work function at the tip apex. The image resolution is limited to (2-2.5 nm), due to quantum mechanical effects and lateral variations in the electron velocity. In field ion microscopy the tip is cooled by a cryogen and its polarity is reversed. When an imaging gas (usually hydrogen or helium) is introduced at low pressures (< 0.1 Pascal) gas ions in the high electric field at the tip apex are field ionized and produce a projected image of protruding atoms at the tip apex. The image resolution is determined primarily by the temperature of the tip but even at 78 Kelvin atomic resolution is achieved. 10-cm Atom Probe The 10-cm Atom Probe, invented in 1973 by J. A. Panitz was a “new and simple atom probe which permits rapid, in depth species identification or the more usual atom-by atom analysis provided by its predecessors ... in an instrument having a volume of less than two liters in which tip movement is unnecessary and the problems of evaporation pulse stability and alignment common to previous designs have been eliminated.” This was accomplished by combining a time of flight (TOF) mass spectrometer with a proximity focussed, dual channel plate detector, an 11.8 cm drift region and a 38° field of view. An FIM image or a desorption image of the atoms removed from the apex of a field emitter tip could be obtained. The 10-cm Atom Probe has been called the progenitor of later atom probes including the commercial instruments. Imaging Atom Probe The Imaging Atom-Probe (IAP) was introduced in 1974 by J. A. Panitz. It incorporated the features of the 10-cm Atom-Probe yet “... departs completely from [previous] atom probe philosophy. Rather than attempt to determine the identity of a surface species producing a preselected ion-image spot, we wish to determine the complete crystallographic distribution of a surface species of preselected mass-to-charge ratio. Now suppose that instead of operating the [detector] continuously, it is turned on for a short time coincidentally with the arrival of a preselected species of interest by applying a gate pulse a time T after the evaporation pulse has reached the specimen. If the duration of the gate pulse is shorter than the travel time between adjacent species, only that surface species having the unique travel time T will be detected and its complete crystallographic distribution displayed.” It was patented in 1975 as the Field Desorption Spectrometer. The Imaging Atom-Probe moniker was coined by A. J. Waugh in 1978 and the instrument was described in detail by J. A. Panitz in the same year. Atom Probe Tomography (APT) Modern day atom probe tomography (APT) uses a position-sensitive detector to deduce the lateral location of atoms. The idea of the APT, inspired by J. A. Panitz's Field Desorption Spectrometer patent, was developed by Mike Miller starting in 1983 and culminated with the first prototype in 1986. Various refinements were made to the instrument, including the use of a so-called position-sensitive (PoS) detector by Alfred Cerezo, Terence Godfrey, and George D. W. Smith at Oxford University in 1988. The Tomographic Atom Probe (TAP), developed by researchers at the University of Rouen in France in 1993, introduced a multichannel timing system and multianode array. Both instruments (PoSAP and TAP) were commercialized by Oxford Nanoscience and CAMECA respectively. Since then, there have been many refinements to increase the field of view, mass and position resolution, and data acquisition rate of the instrument. The Local Electrode Atom Probe was first introduced in 2003 by Imago Scientific Instruments. In 2005, the commercialization of the pulsed laser atom probe (PLAP) expanded the avenues of research from highly conductive materials (metals) to poor conductors (semiconductors like silicon) and even insulating materials. AMETEK acquired CAMECA in 2007 and Imago Scientific Instruments (Madison, WI) in 2010, making the company the sole commercial developer of APTs with more than 110 instruments installed around the world in 2019. The first few decades of work with APT focused on metals. However, with the introduction of the laser pulsed atom probe systems applications have expanded to semiconductors, ceramic and geologic materials, with some work on biomaterials. The most advanced study of biological material to date using APT involved analyzing the chemical structure of teeth of the radula of chiton Chaetopleura apiculata. In this study, the use of APT showed chemical maps of organic fibers in the surrounding nano-crystalline magnetite in the chiton teeth, fibers which were often co-located with sodium or magnesium. This has been furthered to study elephant tusks, dentin and human enamel. Theory Field evaporation Field evaporation is an effect that can occur when an atom bonded at the surface of a material is in the presence of a sufficiently high and appropriately directed electric field, where the electric field is the differential of electric potential (voltage) with respect to distance. Once this condition is met, it is sufficient that local bonding at the specimen surface is capable of being overcome by the field, allowing for evaporation of an atom from the surface to which it is otherwise bonded. Ion flight Whether evaporated from the material itself, or ionised from the gas, the ions that are evaporated are accelerated by electrostatic force, acquiring most of their energy within a few tip-radii of the sample. Subsequently, the accelerative force on any given ion is controlled by the electrostatic equation, where n is the ionisation state of the ion, and e is the fundamental electric charge. This can be equated with the mass of the ion, m, via Newton's law (F=ma): Relativistic effects in the ion flight are usually ignored, as realisable ion speeds are only a very small fraction of the speed of light. Assuming that the ion is accelerated during a very short interval, the ion can be assumed to be travelling at constant velocity. As the ion will travel from the tip at voltage V1 to some nominal ground potential, the speed at which the ion is travelling can be estimated by the energy transferred into the ion during (or near) ionisation. Therefore, the ion speed can be computed with the following equation, which relates kinetic energy to energy gain due to the electric field, the negative arising from the loss of electrons forming a net positive charge. Where U is the ion velocity. Solving for U, the following relation is found: Let's say that for at a certain ionization voltage, a singly charged hydrogen ion acquires a resulting velocity of 1.4x10^6 ms−1 at 10~kV. A singly charged deuterium ion under the sample conditions would have acquired roughly 1.4x10^6/1.41 ms−1. If a detector was placed at a distance of 1 m, the ion flight times would be 1/1.4x10^6 and 1.41/1.4x10^6 s. Thus, the time of the ion arrival can be used to infer the ion type itself, if the evaporation time is known. From the above equation, it can be re-arranged to show that given a known flight distance. F, for the ion, and a known flight time, t, and thus one can substitute these values to obtain the mass-to-charge for the ion. Thus for an ion which traverses a 1 m flight path, across a time of 2000 ns, given an initial accelerating voltage of 5000 V (V in Si units is kg.m^2.s^-3.A^-1) and noting that one amu is 1×10−27 kg, the mass-to-charge ratio (more correctly the mass-to-ionisation value ratio) becomes ~3.86 amu/charge. The number of electrons removed, and thus net positive charge on the ion is not known directly, but can be inferred from the histogram (spectrum) of observed ions. Magnification The magnification in an atom is due to the projection of ions radially away from the small, sharp tip. Subsequently, in the far-field, the ions will be greatly magnified. This magnification is sufficient to observe field variations due to individual atoms, thus allowing in field ion and field evaporation modes for the imaging of single atoms. The standard projection model for the atom probe is an emitter geometry that is based upon a revolution of a conic section, such as a sphere, hyperboloid or paraboloid. For these tip models, solutions to the field may be approximated or obtained analytically. The magnification for a spherical emitter is inversely proportional to the radius of the tip, given a projection directly onto a spherical screen, the following equation can be obtained geometrically. Where rscreen is the radius of the detection screen from the tip centre, and rtip the tip radius. A practical tip to screen distances may range from several centimeters to several meters, with increased detector area required at larger to subtend the same field of view. Practically speaking, the usable magnification will be limited by several effects, such as lateral vibration of the atoms prior to evaporation. Whilst the magnification of both the field ion and atom probe microscopes is extremely high, the exact magnification is dependent upon conditions specific to the examined specimen, so unlike for conventional electron microscopes, there is often little direct control on magnification, and furthermore, obtained images may have strongly variable magnifications due to fluctuations in the shape of the electric field at the surface. Reconstruction The computational conversion of the ion sequence data, as obtained from a position-sensitive detector to a three-dimensional visualisation of atomic types, is termed "reconstruction". Reconstruction algorithms are typically geometrically-based and have several literature formulations. Most models for reconstruction assume that the tip is a spherical object, and use empirical corrections to stereographic projection to convert detector positions back to a 2D surface embedded in 3D space, R3. By sweeping this surface through R3 as a function of the ion sequence input data, such as via ion-ordering, a volume is generated onto which positions the 2D detector positions can be computed and placed three-dimensional space. Typically the sweep takes the simple form of advancement of the surface, such that the surface is expanded in a symmetric manner about its advancement axis, with the advancement rate set by a volume attributed to each ion detected and identified. This causes the final reconstructed volume to assume a rounded-conical shape, similar to a badminton shuttlecock. The detected events thus become a point cloud data with attributed experimentally measured values, such as ion time of flight or experimentally derived quantities, e.g. time of flight or detector data. This form of data manipulation allows for rapid computer visualisation and analysis, with data presented as point cloud data with additional information, such as each ion's mass to charge (as computed from the velocity equation above), voltage or other auxiliary measured quantity or computation therefrom. Data features The canonical feature of atom probe data, is its high spatial resolution in the direction through the material, which has been attributed to an ordered evaporation sequence. This data can therefore image near atomically sharp buried interfaces with the associated chemical information. The data obtained from the evaporative process is however not without artefacts that form the physical evaporation or ionisation process. A key feature of the evaporation or field ion images is that the data density is highly inhomogeneous, due to the corrugation of the specimen surface at the atomic scale. This corrugation gives rise to strong electric field gradients in the near-tip zone (on the order of an atomic radii or less from the tip), which during ionisation deflects ions away from the electric field normal. The resultant deflection means that in these regions of high curvature, atomic terraces are belied by a strong anisotropy in the detection density. Where this occurs due to a few atoms on a surface is usually referred to as a "pole", as these are coincident with the crystallographic axes of the specimen (FCC, BCC, HCP) etc. Where the edges of an atomic terrace causes deflection, a low density line is formed and is termed a "zone line". These poles and zone-lines, whilst inducing fluctuations in data density in the reconstructed datasets, which can prove problematic during post-analysis, are critical for determining information such as angular magnification, as the crystallographic relationships between features are typically well known. When reconstructing the data, owing to the evaporation of successive layers of material from the sample, the lateral and in-depth reconstruction values are highly anisotropic. Determination of the exact resolution of the instrument is of limited use, as the resolution of the device is set by the physical properties of the material under analysis. Systems Many designs have been constructed since the method's inception. Initial field ion microscopes, precursors to modern atom probes, were usually glass blown devices developed by individual research laboratories. System layout At a minimum, an atom probe will consist of several key pieces of equipment. A vacuum system for maintaining the low pressures (~10−8 to 10−10 Pa) required, typically a classic 3 chambered UHV design. A system for the manipulation of samples inside the vacuum, including sample viewing systems. A cooling system to reduce atomic motion, such as a helium refrigeration circuit - providing sample temperatures as low as 15K. A high voltage system to raise the sample standing voltage near the threshold for field evaporation. A high voltage pulsing system, use to create timed field evaporation events A counter electrode that can be a simple disk shape (like the EIKOS™, or earlier generation atom probes), or a cone-shaped Local Electrode, like on a LEAP® system. The voltage pulse (negative) is typically applied to the counter electrode. A detection system for single energetic ions that includes XY position and TOF information. Optionally, an atom probe may also include laser-optical systems for laser beam targeting and pulsing, if using laser-evaporation methods. In-situ reaction systems, heaters, or plasma treatment may also be employed for some studies as well as a pure noble gas introduction for FIM. Performance Collectable ion volumes were previously limited to several thousand, or tens of thousands of ionic events. Subsequent electronics and instrumentation development has increased the rate of data accumulation, with datasets of hundreds of million atoms (dataset volumes of 107 nm3). Data collection times vary considerably depending upon the experimental conditions and the number of ions collected. Experiments take from a few minutes, to many hours to complete. Applications Metallurgy Atom probe has typically been employed in the chemical analysis of alloy systems at the atomic level. This has arisen as a result of voltage pulsed atom probes providing good chemical and sufficient spatial information in these materials. Metal samples from large grained alloys may be simple to fabricate, particularly from wire samples, with hand-electropolishing techniques giving good results. Subsequently, atom probe has been used in the analysis of the chemical composition of a wide range of alloys. Such data is critical in determining the effect of alloy constituents in a bulk material, identification of solid-state reaction features, such as solid phase precipitates. Such information may not be amenable to analysis by other means (e.g. TEM) owing to the difficulty in generating a three-dimensional dataset with composition. Semiconductors Semi-conductor materials are often analysable in atom probe, however sample preparation may be more difficult, and interpretation of results may be more complex, particularly if the semi-conductor contains phases which evaporate at differing electric field strengths. Applications such as ion implantation may be used to identify the distribution of dopants inside a semi-conducting material, which is increasingly critical in the correct design of modern nanometre scale electronics. Limitations Materials implicitly control achievable spatial resolution. Specimen geometry during the analysis is uncontrolled, yet controls projection behaviour, hence there is little control over the magnification. This induces distortions into the computer generated 3D dataset. Features of interest might evaporate in a physically different manner to the bulk sample, altering projection geometry and the magnification of the reconstructed volume. This yields strong spatial distortions in the final image. Volume selectability can be limited. Site specific preparation methods, e.g. using Focussed ion beam preparation, although more time-consuming, may be used to bypass such limitations. Ion overlap in some samples (e.g. between oxygen and sulfur) resulted in ambiguous analysed species. This may be mitigated by selection of experiment temperature or laser input energy to influence the ionisation number (+, ++, 3+ etc.) of the ionised groups. Data analysis can be used in some cases to statistically recover overlaps. Low molecular weight gases (Hydrogen & Helium) may be difficult to be removed from the analysis chamber, and may be adsorbed and emitted from the specimen, even though not present in the original specimen. This may also limit identification of Hydrogen in some samples. For this reason, deuterated samples have been used to overcome limitations. Results may be contingent on the parameters used to convert the 2D detected data into 3D. In more problematic materials, correct reconstruction may not be done, due to limited knowledge of the true magnification; particularly if zone or pole regions cannot be observed.

Al Capone

Alphonse Gabriel Capone (; January 17, 1899 – January 25, 1947), sometimes known by the nickname "Scarface", was an American gangster and businessman who attained notoriety during the Prohibition era as the co-founder and boss of the Chicago Outfit. His seven-year reign as a crime boss ended when he went to prison at the age of 33. Capone was born in New York City in 1899 to Italian immigrant parents. He joined the Five Points Gang as a teenager and became a bouncer in organized crime premises such as brothels. In his early twenties, he moved to Chicago and became a bodyguard and trusted factotum for Johnny Torrio, head of a criminal syndicate that illegally supplied alcohol—the forerunner of the Outfit—and was politically protected through the Unione Siciliana. A conflict with the North Side Gang was instrumental in Capone's rise and fall. Torrio went into retirement after North Side gunmen almost killed him, handing control to Capone. Capone expanded the bootlegging business through increasingly violent means, but his mutually profitable relationships with mayor William Hale Thompson and the city's police meant he seemed safe from law enforcement. Capone apparently reveled in attention, such as the cheers from spectators when he appeared at ball games. He made donations to various charities and was viewed by many as a "modern-day Robin Hood". However, the Saint Valentine's Day Massacre, in which seven gang rivals were murdered in broad daylight, damaged the public image of Chicago and Capone, leading influential citizens to demand government action and newspapers to dub Capone "Public Enemy No.1". The federal authorities became intent on jailing Capone and charged him with 22 counts of tax evasion. He was convicted of five counts in 1931. During a highly publicized case, the judge admitted as evidence Capone's admissions of his income and unpaid taxes, made during prior (and ultimately abortive) negotiations to pay the government taxes he owed. He was convicted and sentenced to 11 years in federal prison. After conviction, he replaced his defense team with experts in tax law, and his grounds for appeal were strengthened by a Supreme Court ruling, but his appeal ultimately failed. Capone showed signs of neurosyphilis early in his sentence and became increasingly debilitated before being released after almost eight years of incarceration. On January 25, 1947, he died of cardiac arrest after suffering a stroke. Early life Capone was born in Brooklyn, New York on January 17, 1899. His parents were Italian immigrants Gabriele Capone (1865–1920) and Teresa Capone (née Raiola; 1867–1952). His father was a barber and his mother was a seamstress, both born in Angri, a small commune outside of Naples in the Province of Salerno. Capone's family had immigrated to the United States in 1893 by ship, first going through Fiume (modern-day Rijeka, Croatia), a port city in what was then Austria-Hungary. The family settled at 95 Navy Street, in the Navy Yard section of Brooklyn, New York City. Gabriele Capone worked at a nearby barber shop at 29 Park Avenue. When Al was 11, he and his family moved to 38 Garfield Place in Park Slope, Brooklyn. Gabriele and Teresa had eight other children: Vincenzo Capone, who later changed his name to Richard Hart and became a Prohibition agent in Homer, Nebraska; Raffaele James Capone, also known as Ralph "Bottles" Capone, who took charge of his brother's beverage industry; Salvatore "Frank" Capone, Ermina Capone, who died at the age of one, Ermino "John" Capone, Albert Capone, Matthew Capone, and Mafalda Capone. Ralph and Frank worked with Al Capone in his criminal empire. Frank did so until his death on April 1, 1924. Ralph ran the bottling companies (both legal and illegal) early on and was also the front man for the Chicago Outfit for some time, until he was imprisoned for tax evasion in 1932. Capone showed promise as a student but had trouble with the rules at his strict parochial Catholic school. His schooling ended at the age of 14 after he was expelled for hitting a female teacher in the face. He worked at odd jobs around Brooklyn, including a candy store and a bowling alley. From 1916 to 1918, he played semi-professional baseball. Following this, Capone was influenced by gangster Johnny Torrio, whom he came to regard as a mentor. Capone married Mae Josephine Coughlin at age 19, on December 30, 1918. She was Irish Catholic and earlier that month had given birth to their son Albert Francis "Sonny" Capone (1918–2004). Albert lost most of his hearing in his left ear as a child. Capone was under the age of 21, and his parents had to consent in writing to the marriage. By all accounts, the two had a happy marriage despite his criminal lifestyle. Career New York City Capone initially became involved with small-time gangs that included the Junior Forty Thieves and the Bowery Boys. He then joined the Brooklyn Rippers, and then the powerful Five Points Gang based in Lower Manhattan. During this time, he was employed and mentored by fellow racketeer Frankie Yale, a bartender in a Coney Island dance hall and saloon called the Harvard Inn. Capone inadvertently insulted a woman while working the door, and he was slashed with a knife three times on the left side of his face by her brother Frank Galluccio; the wounds led to the nickname "Scarface" which Capone loathed. The date when this occurred has been reported with inconsistencies. When Capone was photographed, he hid the scarred left side of his face, saying that the injuries were war wounds. He was called "Snorky" by his closest friends, a term for a sharp dresser. Move to Chicago In 1919, Capone left New York City for Chicago at the invitation of Johnny Torrio, who was imported by crime boss James "Big Jim" Colosimo as an enforcer. Capone began in Chicago as a bouncer in a brothel, where he contracted syphilis. Timely use of Salvarsan probably could have cured the infection, but he apparently never sought treatment. In 1923, he purchased a small house at 7244 South Prairie Avenue in the Park Manor neighborhood in the city's south side for . According to the Chicago Daily Tribune, hijacker Joe Howard was killed on May 7, 1923 after he tried to interfere with the Capone-Torrio bootleg beer business. In the early years of the decade, his name began appearing in newspaper sports pages where he was described as a boxing promoter. Torrio took over Colosimo's crime empire after the latter's murder on May 11, 1920, in which Capone was suspected of being involved. Torrio headed an essentially Italian organized crime group that was the biggest in the city, with Capone as his right-hand man. He was wary of being drawn into gang wars and tried to negotiate agreements over territory between rival crime groups. The smaller North Side Gang led by Dean O'Banion came under pressure from the Genna brothers who were allied with Torrio. O'Banion found that Torrio was unhelpful with the encroachment of the Gennas into the North Side, despite his pretensions to be a settler of disputes. In a fateful step, Torrio arranged the murder of O'Banion at his flower shop on November 10, 1924. This placed Hymie Weiss at the head of the gang, backed by Vincent Drucci and Bugs Moran. Weiss had been a close friend of O'Banion, and the North Siders made it a priority to get revenge on his killers. Al Capone was a frequent visitor to RyeMabee in Monteagle, Tennessee, "when he was traveling between Chicago and his Florida estate in Miami." During Prohibition in the United States, Capone was involved with bootleggers in Canada, who helped him smuggle liquor into the US. When Capone was asked if he knew Rocco Perri, billed as Canada's "King of the Bootleggers", he replied: "Why, I don't even know which street Canada is on." Other sources, however, claim that Capone had certainly visited Canada, where he maintained some hideaways, but the Royal Canadian Mounted Police states that there is no "evidence that he ever set foot on Canadian soil." Boss In January 1925, Capone was ambushed, leaving him shaken but unhurt. Twelve days later, Torrio was returning from a shopping trip when he was shot several times. After recovering, he effectively resigned and handed control to Capone, age 26, who became the new boss of an organization that took in illegal breweries and a transportation network that reached to Canada, with political and law-enforcement protection. In turn, he was able to use more violence to increase revenue. An establishment that refused to purchase liquor from him often got blown up, and as many as 100 people were killed in such bombings during the 1920s. Rivals saw Capone as responsible for the proliferation of brothels in the city. Capone often enlisted the help of local members of the black community into his operations; jazz musicians Milt Hinton and Lionel Hampton had uncles who worked for Capone on the South Side of Chicago. A fan of jazz as well, Capone once asked clarinetist Johnny Dodds to play a number that Dodds did not know; Capone split a $100 bill in half and told Dodds that he would get the other half when he learned it. Capone also sent two bodyguards to accompany jazz pianist Earl Hines on a road trip. Capone indulged in custom suits, cigars, gourmet food and drink, and female companionship. He was particularly known for his flamboyant and costly jewelry. His favorite responses to questions about his activities were: "I am just a businessman, giving the people what they want"; and, "All I do is satisfy a public demand." Capone had become a national celebrity and talking point. He based himself in Cicero, Illinois, after using bribery and widespread intimidation to take over town council elections (such as the 1924 Cicero municipal elections), and this made it difficult for the North Siders to target him. His driver was found tortured and murdered, and there was an attempt on Weiss's life in the Chicago Loop. On September 20, 1926, the North Side Gang used a ploy outside the Capone headquarters at the Hawthorne Inn, aimed at drawing him to the windows. Gunmen in several cars then opened fire with Thompson submachine guns and shotguns at the windows of the first-floor restaurant. Capone was unhurt and called for a truce, but the negotiations fell through. Three weeks later, on October 11, Weiss was killed outside the former O'Banion flower shop North Side headquarters. The owner of Hawthorne's restaurant was a friend of Capone's, and he was kidnapped and killed by Moran and Drucci in January 1927. Reports of Capone's intimidation became well known to the point where it was alleged that some companies, such as the makers of Vine-Glo, would use supposed Capone threats as a marketing tactic. Capone became increasingly security-minded and desirous of getting away from Chicago. As a precaution, he and his entourage would often show up suddenly at one of Chicago's train depots and buy up an entire Pullman sleeper car on a night train to Cleveland, Omaha, Kansas City, Little Rock, or Hot Springs, where they would spend a week in luxury hotel suites under assumed names. In 1928, Capone paid $40,000 to Clarence Busch of the Anheuser-Busch brewing family for a home at 93 Palm Avenue on Palm Island, Florida, in Biscayne Bay between Miami and Miami Beach. Feud with Aiello In November 1925, Antonio Lombardo was named head of the Unione Siciliana, a Sicilian-American benevolent society that had been corrupted by gangsters. An infuriated Joe Aiello, who had wanted the position himself, believed Capone was responsible for Lombardo's ascension and he resented the non-Sicilian's attempts to manipulate affairs within the Unione. Aiello severed all personal and business ties with Lombardo and entered into a feud with him and Capone. Aiello allied himself with several other Capone enemies, including Jack Zuta, who ran vice and gambling houses together. Aiello plotted to eliminate both Lombardo and Capone, and starting in the spring of 1927, made several attempts to assassinate Capone. On one occasion, Aiello offered money to the chef of Joseph "Diamond Joe" Esposito's Bella Napoli Café, Capone's favorite restaurant, to put prussic acid in Capone's and Lombardo's soup; reports indicated he offered between $10,000 and $35,000. Instead, the chef exposed the plot to Capone, who responded by dispatching men to destroy one of Aiello's stores on West Division Street with machine-gun fire. More than 200 bullets were fired into the Aiello Brothers Bakery on May 28, 1927, wounding Joe's brother Antonio. During the summer and autumn of 1927 a number of hitmen Aiello hired to kill Capone were themselves slain. Among them were Anthony Russo and Vincent Spicuzza, each of whom had been offered $25,000 by Aiello to kill Capone and Lombardo. Aiello eventually offered a $50,000 reward to anyone who eliminated Capone. At least 10 gunmen tried to collect on Aiello's bounty, but ended up dead. Capone's ally Ralph Sheldon attempted to kill both Capone and Lombardo for Aiello's reward, but Capone henchman Frank Nitti's intelligence network learned of the transaction and had Sheldon shot in front of a West Side hotel, although he did not die. In November 1927, Aiello organized machine-gun ambushes across from Lombardo's home and a cigar store frequented by Capone, but those plans were foiled after an anonymous tip led police to raid several addresses and arrest Milwaukee gunman Angelo La Mantio and four other Aiello gunmen. After the police discovered receipts for the apartments in La Mantio's pockets, he confessed that Aiello had hired him to kill Capone and Lombardo, leading the police to arrest Aiello himself and bring him to the South Clark Street police station. Upon learning of the arrest, Capone dispatched nearly two dozen gunmen to stand guard outside the station and await Aiello's release. The men made no attempt to conceal their purpose there, and reporters and photographers rushed to the scene to observe Aiello's expected murder. Political alliances The protagonists of Chicago's politics had long been associated with questionable methods, and even newspaper circulation "wars", but the need for bootleggers to have protection in city hall introduced a far more serious level of violence and graft. Capone is generally seen as having an appreciable effect in bringing about the victories of Republican William Hale Thompson, especially in the 1927 mayoral race when Thompson campaigned for a wide-open town, at one time hinting that he'd reopen illegal saloons. Such a proclamation helped his campaign gain the support of Capone, and he allegedly accepted a contribution of $250,000 from the gangster. In the 1927 mayoral race, Thompson beat William Emmett Dever by a relatively slim margin. Thompson's powerful Cook County political machine had drawn on the often-parochial Italian community, but this was in tension with his highly successful courting of African Americans. Another politician, Joe Esposito, became a political rival of Capone, and on March 21, 1928, Esposito was killed in a drive-by shooting in front of his house. Capone continued to back Thompson. Voting booths were targeted by Capone's bomber James Belcastro in the wards where Thompson's opponents were thought to have support, on the polling day of April 10, 1928, in the so-called Pineapple Primary, causing the deaths of at least 15 people. Belcastro was accused of the murder of lawyer Octavius Granady, an African American who challenged Thompson's candidate for the African American vote, and was chased through the streets on polling day by cars of gunmen before being shot dead. Four policemen were among those charged along with Belcastro, but all charges were dropped after key witnesses recanted their statements. An indication of the attitude of local law enforcement toward Capone's organization came in 1931 when Belcastro was wounded in a shooting; police suggested to skeptical journalists that Belcastro was an independent operator. A 1929 report by The New York Times connected Capone to the 1926 murder of Assistant State Attorney William H. McSwiggin, the 1928 murders of chief investigator Ben Newmark and former mentor Frankie Yale. Saint Valentine's Day Massacre Capone was widely assumed to have been responsible for ordering the 1929 Saint Valentine's Day Massacre, despite being at his Florida home at the time of the massacre. The massacre was an attempt to eliminate Bugs Moran, head of the North Side Gang, and the motivation for the plan may have been the fact that some expensive whisky illegally imported from Canada via the Detroit River had been hijacked while it was being transported to Cook County, Illinois. Moran was the last survivor of the North Side gunmen; his succession had come about because his similarly aggressive predecessors, Weiss and Vincent Drucci, had been killed in the violence that followed the murder of original leader Dean O'Banion. To monitor their targets' habits and movements, Capone's men rented an apartment across from the trucking warehouse and garage at 2122 North Clark Street, which served as Moran's headquarters. On the morning of Thursday, February 14, 1929, Capone's lookouts signaled four gunmen disguised as police officers to initiate a "police raid". The faux police lined the seven victims along a wall and signaled for accomplices armed with machine guns and shotguns. Moran was not among the victims. Photos of the slain victims shocked the public and damaged Capone's image. Within days, Capone received a summons to testify before a Chicago grand jury on charges of federal Prohibition violations, but he claimed to be too unwell to attend. In an effort to clean up his image, Capone donated to charities and sponsored a soup kitchen in Chicago during the Depression. The Saint Valentine's Day Massacre led to public disquiet about Thompson's alliance with Capone and was a factor in Anton J. Cermak winning the mayoral election on April 6, 1931. Feud with Aiello ends Capone was primarily known for ordering other men to do his dirty work for him. In May 1929, one of Capone's bodyguards, Frank Rio, uncovered a plot by three of his men, Albert Anselmi, John Scalise and Joseph Giunta, who had been persuaded by Aiello to depose Capone and take over the Chicago Outfit. Capone later beat the men with a baseball bat and then ordered his bodyguards to shoot them, a scene that was included in the 1987 film The Untouchables. Deirdre Bair, along with writers and historians such as William Elliot Hazelgrove, have questioned the veracity of the claim. Bair questioned why "three trained killers could sit quietly and let this happen", while Hazelgrove stated that Capone would have been "hard pressed to beat three men to death with a baseball bat" and that he would have instead let an enforcer perform the murders. However, despite claims that the story was first reported by author Walter Noble Burns in his 1931 book The One-way Ride: The red trail of Chicago gangland from prohibition to Jake Lingle, Capone biographers Max Allan Collins and A. Brad Schwartz have found versions of the story in press coverage shortly after the crime. Collins and Schwartz suggest that similarities among reported versions of the story indicate a basis in truth and that the Outfit deliberately spread the tale to enhance Capone's fearsome reputation. George Meyer, an associate of Capone's, also claimed to have witnessed both the planning of the murders and the event itself. In 1930, upon learning of Aiello's continued plotting against him, Capone resolved to finally eliminate him. In the weeks before Aiello's death Capone's men tracked him to Rochester, New York, where he had connections through Buffalo crime family boss Stefano Magaddino, and plotted to kill him there, but Aiello returned to Chicago before the plot could be executed. Aiello, angst-ridden from the constant need to hide out and the killings of several of his men, set up residence in the Chicago apartment of Unione Siciliana treasurer Pasquale "Patsy Presto" Prestogiacomo at 205 N. Kolmar Ave. On October 23, upon exiting Prestogiacomo's building to enter a taxicab, a gunman in a second-floor window across the street started firing at Aiello with a submachine gun. Aiello was said to have been shot at least 13 times before he toppled off the building steps and moved around the corner, attempting to move out of the line of fire. Instead, he moved directly into the range of a second submachine gun positioned on the third floor of another apartment block, and was subsequently gunned down. Federal intervention In the wake of the Saint Valentine's Day Massacre, Walter A. Strong, publisher of the Chicago Daily News, decided to ask his friend President Herbert Hoover for federal intervention to stem Chicago's lawlessness. He arranged a secret meeting at the White House, just two weeks after Hoover's inauguration. On March 19, 1929, Strong, joined by Frank Loesch of the Chicago Crime Commission, and Laird Bell, made their case to the President. In Hoover's 1952 Memoir, the former President reported that Strong argued "Chicago was in the hands of the gangsters, that the police and magistrates were completely under their control, …that the Federal government was the only force by which the city’s ability to govern itself could be restored. At once I directed that all the Federal agencies concentrate upon Mr. Capone and his allies." That meeting launched a multi-agency attack on Capone. Treasury and Justice Departments developed plans for income tax prosecutions against Chicago gangsters, and a small, elite squad of Prohibition Bureau agents (whose members included Eliot Ness) were deployed against bootleggers. In a city used to corruption, these lawmen were incorruptible. Charles Schwarz, a writer for the Chicago Daily News, dubbed them Untouchables. To support Federal efforts, Strong secretly used his newspaper's resources to gather and share intelligence on the Capone outfit. Trials On March 27, 1929, Capone was arrested by FBI agents as he left a Chicago courtroom after testifying to a grand jury that was investigating violations of federal prohibition laws. He was charged with contempt of court for feigning illness to avoid an earlier appearance. On May 16, 1929, Capone was arrested in Philadelphia, Pennsylvania, for carrying a concealed weapon. On May 17, 1929, Capone was indicted by a grand jury and a trial was held before Philadelphia Municipal Court Judge John E Walsh. Following the entering of a guilty plea by his attorney, Capone was sentenced to a prison term of one year. On August 8, 1929, Capone was transferred to Philadelphia's Eastern State Penitentiary. A week after his release in March 1930, Capone was listed as the number one "Public Enemy" on the unofficial Chicago Crime Commission's widely publicized list. In April 1930, Capone was arrested on vagrancy charges when visiting Miami Beach; the governor had ordered sheriffs to run him out of the state. Capone claimed that Miami police had refused him food and water and threatened to arrest his family. He was charged with perjury for making these statements, but was acquitted after a three-day trial in July. In September, a Chicago judge issued a warrant for Capone's arrest on charges of vagrancy and then used the publicity to run against Thompson in the Republican primary. In February 1931, Capone was tried on the contempt of court charge. In court, Judge James Herbert Wilkerson intervened to reinforce questioning of Capone's doctor by the prosecutor. Wilkerson sentenced Capone to six months, but he remained free while on appeal of the contempt conviction. In February 1930, Capone's organization was linked to the murder of Julius Rosenheim, who served as a police informant in the Chicago Outfit for 20 years. Tax evasion Assistant Attorney General Mabel Walker Willebrandt recognized that mob figures publicly led lavish lifestyles yet never filed tax returns, and thus could be convicted of tax evasion without requiring hard evidence to get testimony about their other crimes. She tested this approach by prosecuting a South Carolina bootlegger, Manley Sullivan. In 1927, the Supreme Court ruled in United States v. Sullivan that the approach was legally sound: illegally earned income was subject to income tax; Justice Oliver Wendell Holmes Jr. rejected the argument that the Fifth Amendment protected criminals from reporting illegal income. The IRS special investigation unit chose Frank J. Wilson to investigate Capone, with the focus on his spending. The key to Capone's conviction on tax charges was proving his income, and the most valuable evidence in that regard originated in his offer to pay tax. Ralph, his brother and a gangster in his own right, was tried for tax evasion in 1930. Ralph spent the next three years in prison after being convicted in a two-week trial over which Wilkerson presided. Capone ordered his lawyer to regularize his tax position. Crucially, during the ultimately abortive negotiations that followed, his lawyer stated the income that Capone was willing to pay tax on for various years, admitting income of $100,000 for 1928 and 1929, for instance. Hence, without any investigation, the government had been given a letter from a lawyer acting for Capone conceding his large taxable income for certain years. On March 13, 1931, Capone was charged with income tax evasion for 1924, in a secret grand jury. On June 5, 1931, Capone was indicted by a federal grand jury on 22 counts of income tax evasion from 1925 through 1929; he was released on $50,000 bail. A week later, Eliot Ness and his team of Untouchables inflicted major financial damage on Capone's operations and led to his indictment on 5,000 violations of the Volstead Act (Prohibition laws). On June 16, 1931, at the Chicago Federal Building in the courtroom of Wilkerson, Capone pleaded guilty to income tax evasion and the 5,000 Volstead Act violations as part of a -year prison sentence plea bargain. However, on July 30, 1931, Wilkerson refused to honor the plea bargain, and Capone's counsel rescinded the guilty pleas. On the second day of the trial, Wilkerson overruled objections that a lawyer could not confess for his client, saying that anyone making a statement to the government did so at his own risk. Wilkerson deemed that the 1930 letter to federal authorities could be admitted into evidence from a lawyer acting for Capone. Wilkerson later tried Capone only on the income tax evasion charges as he determined they took precedence over the Volstead Act charges. Much was later made of other evidence, such as witnesses and ledgers, but these strongly implied Capone's control rather than stating it. Capone's lawyers, who had relied on the plea bargain Wilkerson refused to honor and therefore had mere hours to prepare for the trial, ran a weak defense focused on claiming that essentially all his income was lost to gambling. This would have been irrelevant regardless, since gambling losses can only be subtracted from gambling winnings, but it was further undercut by Capone's expenses, which were well beyond what his claimed income could support; Wilkerson allowed Capone's spending to be presented at very great length. The government charged Capone with evasion of $215,000 in taxes on a total income of $1,038,654, during the five-year period. Capone was convicted on five counts of income tax evasion on October 17, 1931, and was sentenced a week later to 11 years in federal prison, fined $50,000 plus $7,692 for court costs, and was held liable for $215,000 plus interest due on his back taxes. The contempt of court sentence was served concurrently. New lawyers hired to represent Capone were Washington-based tax experts. They filed a writ of habeas corpus based on a Supreme Court ruling that tax evasion was not fraud, which apparently meant that Capone had been convicted on charges relating to years that were actually outside the time limit for prosecution. However, a judge interpreted the law so that the time that Capone had spent in Miami was subtracted from the age of the offences, thereby denying the appeal of both Capone's conviction and sentence. Imprisonment Capone was sent to Atlanta U.S. Penitentiary in May 1932, aged 33. Upon his arrival at Atlanta, Capone was officially diagnosed with syphilis and gonorrhoea. He was also suffering from withdrawal symptoms from cocaine addiction, the use of which had perforated his nasal septum. Capone was competent at his prison job of stitching soles on shoes for eight hours a day, but his letters were barely coherent. He was seen as a weak personality, and so out of his depth dealing with bullying fellow inmates that his cellmate, seasoned convict Red Rudensky, feared that Capone would have a breakdown. Rudensky was formerly a small-time criminal associated with the Capone gang and found himself becoming a protector for Capone. The conspicuous protection of Rudensky and other prisoners drew accusations from less friendly inmates and fueled suspicion that Capone was receiving special treatment. No solid evidence ever emerged, but it formed part of the rationale for moving Capone to the recently opened Alcatraz Federal Penitentiary off the coast of San Francisco, in August 1934. On June 23, 1936, Capone was stabbed and superficially wounded by fellow-Alcatraz inmate James C. Lucas. Due to his good behavior, Capone was permitted to play banjo in the Alcatraz prison band, the Rock Islanders, which gave regular Sunday concerts for other inmates. Capone also transcribed the song “Madonna Mia” creating his own arrangement as a tribute to his wife Mae. At Alcatraz, Capone's decline became increasingly evident, as neurosyphilis progressively eroded his mental faculties; his formal diagnosis of syphilis of the brain was made in February 1938. He spent the last year of his Alcatraz sentence in the hospital section, confused and disoriented. Capone completed his term in Alcatraz on January 6, 1939, and was transferred to the Federal Correctional Institution at Terminal Island in California to serve out his sentence for contempt of court. He was paroled on November 16, 1939, after his wife Mae appealed to the court, based on his reduced mental capabilities. Chicago aftermath The main effect of Capone's conviction was that he ceased to be boss immediately on his imprisonment, but those involved in the jailing of Capone portrayed it as considerably undermining the city's organized crime syndicate. Capone's underboss, Frank Nitti, took over as boss of the Outfit after he was released from prison in March 1932, having also been convicted of tax evasion charges. Far from being smashed, the Outfit continued without being troubled by the Chicago police, but at a lower level and without the open violence that had marked Capone's rule. Organized crime in the city had a lower profile once Prohibition was repealed, already wary of attention after seeing Capone's notoriety bring him down, to the extent that there is a lack of consensus among writers about who was actually in control and who was a figurehead "front boss". Prostitution, labor union racketeering, and gambling became moneymakers for organized crime in the city without incurring serious investigation. In the late 1950s, FBI agents discovered an organization led by Capone's former lieutenants reigning supreme over the Chicago underworld. Some historians have speculated that Capone ordered the 1939 murder of Edward J. O'Hare a week before his release, for helping federal prosecutors convict Capone of tax evasion, though there are other theories for O'Hare's death. Failing health and death Due to his failing health, Capone was released from prison on November 16, 1939, and referred to the Johns Hopkins Hospital in Baltimore for the treatment of syphilitic paresis. Due to his unsavory reputation, Johns Hopkins refused to treat him, however nearby Union Memorial Hospital was still willing to treat him. Capone was grateful for the compassionate care that he received and donated two Japanese weeping cherry trees to Union Memorial Hospital in 1939. After a few weeks of inpatient and outpatient care, on March 20, 1940 a very sickly Capone left Baltimore and travelled to his mansion in Palm Island, Florida. In 1942, after mass production of penicillin was started in the United States, Capone was one of the first American patients treated by the new drug. Though it was too late for him to reverse the damage to his brain, it did slow down the progression of the disease. In 1946, his physician and a Baltimore psychiatrist examined him and concluded that Capone had the mentality of a 12-year-old child. He spent the last years of his life at his mansion in Palm Island, Florida, spending time with his wife and grandchildren. On January 21, 1947, Capone had a stroke. He regained consciousness and started to improve, but contracted bronchopneumonia. He suffered a cardiac arrest on January 22, and on January 25, surrounded by his family in his home, Capone died after his heart failed as a result of apoplexy. His body was transported back to Chicago a week later and a private funeral was held. He was originally buried at Mount Olivet Cemetery in Chicago. In 1950, Capone's remains, along with those of his father, Gabriele, and brother, Salvatore, were moved to Mount Carmel Cemetery in Hillside, Illinois. In popular culture Capone is one of the most notorious American gangsters of the 20th century and has been the major subject of numerous articles, books, and films. Particularly, from 1925 to 1929, shortly after he relocated to Chicago, he enjoyed status as the most notorious mobster in the country. He cultivated a certain image of himself in the media, that made him a subject of fascination. His personality and character have been used in fiction as a model for crime lords and criminal masterminds ever since his death. The stereotypical image of a mobster wearing a pinstriped suit and tilted fedora are based on photos of Capone. His accent, mannerisms, facial construction, physical stature, and parodies of his name have been used for numerous gangsters in comics, movies, music, and literature.

Amplifier figures of merit

In electronics, the figures of merit of an amplifier are numerical measures that characterize its properties and performance. Figures of merit can be given as a list of specifications that include properties such as gain, bandwidth, noise and linearity, among others listed in this article. Figures of merit are important for determining the suitability of a particular amplifier for an intended use. Gain The gain of an amplifier is the ratio of output to input power or amplitude, and is usually measured in decibels. When measured in decibels it is logarithmically related to the power ratio: G(dB)=10 log(Pout /Pin). RF amplifiers are often specified in terms of the maximum power gain obtainable, while the voltage gain of audio amplifiers and instrumentation amplifiers will be more often specified. For example, an audio amplifier with a gain given as 20 dB will have a voltage gain of ten. The use of voltage gain figure is appropriate when the amplifier's input impedance is much higher than the source impedance, and the load impedance higher than the amplifier's output impedance. If two equivalent amplifiers are being compared, the amplifier with higher gain settings would be more sensitive as it would take less input signal to produce a given amount of power. Bandwidth The bandwidth of an amplifier is the range of frequencies for which the amplifier gives "satisfactory performance". The definition of "satisfactory performance" may be different for different applications. However, a common and well-accepted metric is the half-power points (i.e. frequency where the power goes down by half its peak value) on the output vs. frequency curve. Therefore, bandwidth can be defined as the difference between the lower and upper half power points. This is therefore also known as the bandwidth. Bandwidths (otherwise called "frequency responses") for other response tolerances are sometimes quoted (, etc.) or "plus or minus 1dB" (roughly the sound level difference people usually can detect). The gain of a good quality full-range audio amplifier will be essentially flat between 20 Hz to about 20 kHz (the range of normal human hearing). In ultra-high-fidelity amplifier design, the amplifier's frequency response should extend considerably beyond this (one or more octaves either side) and might have points < 10 Hz and > . Professional touring amplifiers often have input and/or output filtering to sharply limit frequency response beyond ; too much of the amplifier's potential output power would otherwise be wasted on infrasonic and ultrasonic frequencies, and the danger of AM radio interference would increase. Modern switching amplifiers need steep low pass filtering at the output to get rid of high-frequency switching noise and harmonics. The range of frequency over which the gain is equal to or greater than 70.7% of its maximum gain is termed as bandwidth. Efficiency Efficiency is a measure of how much of the power source is usefully applied to the amplifier's output. Class A amplifiers are very inefficient, in the range of 10–20% with a max efficiency of 25% for direct coupling of the output. Inductive coupling of the output can raise their efficiency to a maximum of 50%. Drain efficiency is the ratio of output RF power to input DC power when primary input DC power has been fed to the drain of a field-effect transistor. Based on this definition, the drain efficiency cannot exceed 25% for a class A amplifier that is supplied drain bias current through resistors (because RF signal has its zero level at about 50% of the input DC). Manufacturers specify much higher drain efficiencies, and designers are able to obtain higher efficiencies by providing current to the drain of the transistor through an inductor or a transformer winding. In this case the RF zero level is near the DC rail and will swing both above and below the rail during operation. While the voltage level is above the DC rail current is supplied by the inductor. Class B amplifiers have a very high efficiency but are impractical for audio work because of high levels of distortion (See: Crossover distortion). In practical design, the result of a tradeoff is the class AB design. Modern Class AB amplifiers commonly have peak efficiencies between 30 and 55% in audio systems and 50-70% in radio frequency systems with a theoretical maximum of 78.5%. Commercially available Class D switching amplifiers have reported efficiencies as high as 90%. Amplifiers of Class C-F are usually known to be very high-efficiency amplifiers. RCA manufactured an AM broadcast transmitter employing a single class-C low-mu triode with an RF efficiency in the 90% range. More efficient amplifiers run cooler, and often do not need any cooling fans even in multi-kilowatt designs. The reason for this is that the loss of efficiency produces heat as a by-product of the energy lost during the conversion of power. In more efficient amplifiers there is less loss of energy so in turn less heat. In RF linear Power Amplifiers, such as cellular base stations and broadcast transmitters, special design techniques can be used to improve efficiency. Doherty designs, which use a second output stage as a "peak" amplifier, can lift efficiency from the typical 15% up to 30-35% in a narrow bandwidth. Envelope Tracking designs are able to achieve efficiencies of up to 60%, by modulating the supply voltage to the amplifier in line with the envelope of the signal. Linearity An ideal amplifier would be a totally linear device, but real amplifiers are only linear within limits. When the signal drive to the amplifier is increased, the output also increases until a point is reached where some part of the amplifier becomes saturated and cannot produce any more output; this is called clipping, and results in distortion. In most amplifiers a reduction in gain takes place before hard clipping occurs; the result is a compression effect, which (if the amplifier is an audio amplifier) sounds much less unpleasant to the ear. For these amplifiers, the 1 dB compression point is defined as the input power (or output power) where the gain is 1 dB less than the small signal gain. Sometimes this non linearity is deliberately designed in to reduce the audible unpleasantness of hard clipping under overload. Ill effects of non-linearity can be reduced with negative feedback. Linearization is an emergent field, and there are many techniques, such as feed forward, predistortion, postdistortion, in order to avoid the undesired effects of the non-linearities. Noise This is a measure of how much noise is introduced in the amplification process. Noise is an undesirable but inevitable product of the electronic devices and components; also, much noise results from intentional economies of manufacture and design time. The metric for noise performance of a circuit is noise figure or noise factor. Noise figure is a comparison between the output signal to noise ratio and the thermal noise of the input signal. Output dynamic range Output dynamic range is the range, usually given in dB, between the smallest and largest useful output levels. The lowest useful level is limited by output noise, while the largest is limited most often by distortion. The ratio of these two is quoted as the amplifier dynamic range. More precisely, if S = maximal allowed signal power and N = noise power, the dynamic range DR is DR = (S + N ) /N. In many switched mode amplifiers, dynamic range is limited by the minimum output step size. Slew rate Slew rate is the maximum rate of change of the output, usually quoted in volts per second (or microsecond). Many amplifiers are ultimately slew rate limited (typically by the impedance of a drive current having to overcome capacitive effects at some point in the circuit), which sometimes limits the full power bandwidth to frequencies well below the amplifier's small-signal frequency response. Rise time The rise time, tr, of an amplifier is the time taken for the output to change from 10% to 90% of its final level when driven by a step input. For a Gaussian response system (or a simple RC roll off), the rise time is approximated by: tr * BW = 0.35, where tr is rise time in seconds and BW is bandwidth in Hz. Settling time and ringing The time taken for the output to settle to within a certain percentage of the final value (for instance 0.1%) is called the settling time, and is usually specified for oscilloscope vertical amplifiers and high-accuracy measurement systems. Ringing refers to an output variation that cycles above and below an amplifier's final value and leads to a delay in reaching a stable output. Ringing is the result of overshoot caused by an underdamped circuit. Overshoot In response to a step input, the overshoot is the amount the output exceeds its final, steady-state value. Stability Stability is an issue in all amplifiers with feedback, whether that feedback is added intentionally or results unintentionally. It is especially an issue when applied over multiple amplifying stages. Stability is a major concern in RF and microwave amplifiers. The degree of an amplifier's stability can be quantified by a so-called stability factor. There are several different stability factors, such as the Stern stability factor and the Linvil stability factor, which specify a condition that must be met for the absolute stability of an amplifier in terms of its two-port parameters.

Army of Darkness

Army of Darkness is a 1992 American horror comedy film directed, co-written and co-edited by Sam Raimi, co-produced by Robert Tapert and Bruce Campbell and co-written by Ivan Raimi. Starring Campbell and Embeth Davidtz, it is the third installment in the Evil Dead franchise, and a sequel to Evil Dead II, and follows Ash Williams (Campbell) as he is trapped in the Middle Ages and battles the undead in his quest to return to the present. The film was produced as part of a production deal with Universal Pictures after the financial success of Darkman. Filming took place in California in 1991. The makeup and creature effects for the film were handled by two different companies: Tony Gardner and his company Alterian, Inc., were responsible for the makeup effects for Ash and Sheila, while Kurtzman, Nicotero & Berger EFX Group was credited for the remaining special makeup effects characters. Tom Sullivan, who had previously worked on Within the Woods, The Evil Dead, and Evil Dead II, also contributed to the visual effects. Army of Darkness premiered at the Sitges Film Festival on October 9, 1992, and was released in the United States on February 19, 1993. It grossed $21.5 million total over its $11 million budget, and received positive reviews, though notably less than the first two films. Since its video release, it has acquired a cult following, along with the other two films in the trilogy. The film was dedicated to The Evil Dead sales agent and Evil Dead II executive producer Irvin Shapiro, who died before the film's production in 1989. Plot Having been accidentally transported to the Middle Ages, Ash Williams is captured by Lord Arthur's men, who suspect him of being a spy for Duke Henry, with whom Arthur is at war. He is enslaved along with the captured Henry, his shotgun and chainsaw are confiscated, and he is taken to Arthur's castle. Ash is thrown in a pit where he kills a Deadite and regains his weapons from Arthur's Wise Man. After demanding that Henry and his men be set free and killing a Deadite publicly, Ash is celebrated as a hero. He grows attracted to Sheila, the sister of one of Arthur's fallen knights. According to the Wise Man, the only way that Ash can return to his time is through the magical Necronomicon Ex-Mortis. Ash then starts his search for the Necronomicon. As he enters a haunted forest, an unseen force pursues Ash into a windmill, and he crashes into a mirror. Small reflections of Ash in the mirror shards come to life, with one becoming a life-sized copy of him, after which Ash kills and buries it. When he arrives at the Necronomicons location, he finds three books instead of one, and has to determine which one is real. Realizing at the last moment that he has forgotten the last word of the phrase that will allow him to remove the book safely "Klaatu barada nikto" he tries to mumble and cough his way through the pronunciation. He grabs the book and begins rushing back. Meanwhile, unknown to Ash, his ruse has failed and his body's copy rises from the dead, uniting other Deadites into the Army of Darkness. Upon his return, Ash demands to be returned to his own time. However, Sheila is abducted by a flying Deadite and later transformed into one. Ash becomes determined to lead the outnumbered humans against the Army, and the people reluctantly agree. Using knowledge from textbooks in his 1973 Oldsmobile Delta 88 and enlisting the help of Duke Henry, Ash successfully leads the soldiers to victory over the Deadites and their captain, saves Sheila, and brings peace between Arthur and Henry. Using a passage from the Necronomicon, the Wise Man tells him how to return to the present by giving him a potion after reciting the same phrase as earlier in the film. Back in the present, Ash recounts his story to a fellow employee at the S-Mart department store. As he talks to a female co-worker who is interested in his story, a surviving Deadite, allowed to come to the present because Ash once again forgot the last word, attacks the customers. Ash kills it using a Winchester rifle and exclaims, "Hail to the king, baby", before passionately kissing the female co-worker. Original ending For the film's original ending, using a passage from the Necronomicon, the Wise Man tells Ash to swallow six drops of the potion to return to the present, unfortunately, due to a distraction by falling rocks, Ash miscalculates the amount of potion needed to be able to correctly return to his own time, swallowing seven instead of six. As a result, he wakes up in a post-apocalyptic future where human civilization is destroyed, and he screams in dismay at having overslept. Universal Pictures objected to this climax, feeling that it was too negative and depressing in tone, and so a more positive and optimistic ending was filmed and ultimately incorporated into the theatrical cut.

Evil Dead II made enough money internationally that Dino De Laurentiis was willing to finance a sequel. Director and script writer Sam Raimi drew from a variety of sources, including literature with A Connecticut Yankee in King Arthur's Court and Jonathan Swift's Gulliver's Travels and films like The 7th Voyage of Sinbad, Jason and the Argonauts, The Three Stooges, and Conan the Barbarian. Evil Dead II, according to Bruce Campbell, "was originally designed to go back into the past to 1300, but we couldn't muster it at the time, so we decided to make an interim version, not knowing if the 1300 story would ever get made". Promotional drawings were created and published in Variety during the casting process before the budget was deemed too little for the plot. The working title for the project was Medieval Dead, before it was later known as Evil Dead III: Army of Darkness. The title "Army of Darkness" came from an idea by Irvin Shapiro, during the production of Evil Dead II. Writing Initially, Raimi invited Scott Spiegel to co-write Army of Darkness because he had done a good job on Evil Dead II, but he was busy on rewrites for the Clint Eastwood film The Rookie. After the good experience of writing the screenplay for a film called Easy Wheels, Sam and his brother Ivan decided to co-write the film together. They worked on the script throughout the pre-production and production of Darkman. After filming Darkman, they took the script out and worked on it in more detail. Raimi says that Ivan "has a good sense of character" and that he brought more comedy into the script. Campbell remembers, "We all decided, 'Get him out of the cabin.' There were earlier drafts where part three still took place there, but we thought, 'Well, we all know that cabin, it's time to move on.' The three of us decided to keep it in 1300, because it's more interesting". Campbell and Tapert would read the script drafts, give Raimi their notes and he would decide which suggestions to keep and which ones to discard. Pre-production The initial budget was $8 million but during pre-production, it became obvious that this was not going to be enough. Darkman was also a financial success and De Laurentiis had a multi-picture deal with Universal and so Army of Darkness became one of the films. The studio decided to contribute half of the film's $12 million budget. However, the film's ambitious scope and its extensive effects work forced Campbell, Raimi and producer Robert Tapert to put up $1 million of their collective salaries to shoot a new ending and not film a scene where a possessed woman pushes down some giant pillars. Visual effects supervisor William Mesa showed Raimi storyboards he had from Victor Fleming's film Joan of Arc that depicted huge battle scenes and he picked out 25 shots to use in Army of Darkness. A storyboard artist worked closely with the director in order to blend the shots from the Joan of Arc storyboards with the battle scenes in his film. Traci Lords was among the actresses auditioning for the film, saying in 2001, "I didn't get the part but I clicked with Bruce [Campbell]," with whom she would later work as a guest star in the TV series Hercules: The Legendary Journeys. Filming Principal photography took place between soundstage and on-location work. Army of Darkness was filmed in Bronson Canyon and Vasquez Rocks Natural Area Park. The interior shots were filmed on an Introvision stage in Hollywood. Raimi's use of the Introvision process was a tribute to the stop-motion animation work of Ray Harryhausen. Introvision uses front-projected images with live actors instead of the traditional rear projection that Harryhausen and others used. Introvision blended components with more realistic-looking results. To achieve this effect, Raimi used 60-foot-tall Scotchlite front-projection screens, miniatures and background plates. According to the director, the advantage of using this technique was "the incredible amount of interaction between the background, which doesn't exist, and the foreground, which is usually your character". Shooting began in mid-1991, and it lasted for about 100 days. It was a mid-summer shoot and while on location on a huge castle set that was built near Acton, California, on the edge of the Mojave Desert, the cast and crew endured very hot conditions during the day and very cold temperatures at night. Most of the film took place at night and the filmmakers shot most of the film during the summer when the days were longest and the nights were the shortest. It would take an hour and a half to light an area leaving the filmmakers only six hours left to shoot a scene. Money problems forced cinematographer Bill Pope to shoot only for certain hours Monday through Friday because he could not be paid his standard fee. Mesa shot many of the action sequences on the weekend. It was a difficult shoot for Campbell who had to learn elaborate choreography for the battle scenes, which involved him remembering a number system because the actor was often fighting opponents that were not really there. Mesa remembers, "Bruce was cussing and swearing some of the time because you had to work on the number system. Sam would tell us to make it as complicated and hard for Bruce as possible. 'Make him go through torture!' So we'd come up with these shots that were really, really difficult, and sometimes they would take thirty-seven takes". Some scenes, like Evil Ash walking along the graveyard while his skeleton minions come to life, blended stop-motion animation with live-action skeleton puppets that were mechanically rigged, with prosthetics and visual effects. Post-production While Dino De Laurentiis gave Raimi and his crew freedom to shoot the film the way they wanted, Universal took over during post-production. Universal was not happy with Raimi's cut because it did not like his original ending, feeling it was negative. In this ending, the potion Ash is given causes him to oversleep, and when he wakes up he is in a futuristic, post-apocalyptic wasteland. A more upbeat ending was shot a month later in a lumber store in Malibu, California. Then, two months after principal filming was finished, a round of re-shoots began in Santa Monica and involved Ash in the windmill and the scenes with Bridget Fonda. Raimi recalls, "Actually, I kind of like the fact that there are two endings, that in one alternate universe Bruce is screwed, and in another universe he's some cheesy hero". Raimi needed $3 million to finish his film, but Universal was not willing to give him the money and delayed its release due to a dispute with De Laurentiis over the rights to the Hannibal Lecter character which Universal needed so that they could film a sequel to The Silence of the Lambs. The matter was finally resolved, but the release date for Army of Darkness''' was pushed back from summer of 1992 to February 1993. For the film's poster, Universal brought Campbell in to take several reference head shots and asked him to strike a sly look on his face. They showed him a rough of the Frank Frazetta-like painting. The actor had a day to approve it or, as he was told, there would be no ad campaign for the film. Raimi ran into further troubles when the Motion Picture Association of America gave it an NC-17 rating for a shot of a female Deadite being killed early on in the film. Universal wanted a PG-13 rating, so Raimi made a few cuts and was still stuck with an R rating. In response, Universal turned the film over to outside film editors who cut the film to 81 minutes and another version running 87 minutes that was eventually released in theaters, still with an R rating. Music Danny Elfman, who composed the score for Darkman, wrote the "March of the Dead" theme for Army of Darkness. After the re-shoots were completed, Joseph LoDuca, who composed the music for The Evil Dead and Evil Dead II, returned to score the film. The composer used his knowledge of synthesizers and was able to present many cues in a mock-up form before he recorded them with the Seattle Symphony. A vinyl release of the score was revealed during the MondoCon in Austin, Texas, on October 3 and 4, 2015 over Mondo Records. Reception Box officeArmy of Darkness was released by Universal on February 19, 1993, in 1,387 theaters in the United States, grossing $4.4 million (38.5% of total gross) in its first weekend. On a budget of $11 million, the film earned $11.5 million in the US and $21.5 million worldwide. Critical response The film holds a 73% approval rating on the review aggregator website Rotten Tomatoes based on 48 reviews, with a weighted average of 6.9/10; making its critical reception above average but much lower than The Evil Dead and Evil Dead II, which both received 95%. The site's consensus reads, "Army Of Darkness is a madcap adventure worth taking thanks to Bruce Campbell's hammy charm and Sam Raimi's acrobatic direction, although an intentional lack of shocks makes this a discordant capper to the Evil Dead franchise". On Metacritic, the film holds a score of 57 out of 100, indicating "mixed or average reviews". Roger Ebert gave the film two out of four stars and wrote, "The movie isn't as funny or entertaining as Evil Dead II, however, maybe because the comic approach seems recycled." In her review for The New York Times, Janet Maslin wrote that "Mr. Campbell's manly, mock-heroic posturing is perfectly in keeping with the director's droll outlook." Desson Howe, in his review for The Washington Post praised the film's style: "Bill Pope's cinematography is gymnastic and appropriately frenetic. The visual and make-up effects (from artist-technicians William Mesa, Tony Gardner and others) are incredibly imaginative." However, Entertainment Weekly gave the film a "C+" rating and wrote, "This spoofy cast of thousands looks a little too much like a crew of bland Hollywood extras. By the time Army of Darkness turns into a retread of Jason and the Argonauts, featuring an army of fighting skeletons, the film has fallen into a ditch between parody and spectacle." AccoladesArmy of Darkness won the Saturn Award for Best Horror Film (1994). It was also nominated for Best Make-Up. Army of Darkness was nominated for the Grand Prize at Avoriaz Fantastic Film Festival, and won the Golden Raven at the Brussels International Festival of Fantasy Film in 1993. The film also won the Critics' Award at Fantasporto, and was nominated for the International Fantasy Film Award in the category of Best Film in 1993. It was also nominated for Best Film at Sitges, the Spanish International Film Festival. Other media Future In March 2013, shortly before the release of Evil Dead, a loose continuation of the franchise, Raimi confirmed that the next Evil Dead film will be Army of Darkness 2. Campbell confirmed that he would star as an older, but not necessarily wiser, Ash. At a WonderCon panel in March 2013, Campbell and Fede Álvarez, director of the 2013 film, stated that their ultimate plan was for Álvarez's Evil Dead 2 and Raimi's Army of Darkness 2 to be followed by a seventh film which would merge the narratives of Ash and Mia. On October 18, 2013, Campbell once again confirmed in an interview with ComicBook.com that he will be reprising his role as Ash in the sequel. Fede Álvarez posted a status update on his Twitter account that Raimi will direct the sequel. Campbell later commented that the rumor about him returning is false. In July 2014, Campbell stated it was likely the planned sequel would instead be a TV series with him as the star. The ten-episode season of Ash vs Evil Dead premiered on Starz on October 31, 2015, with the pilot co-written and directed by Sam Raimi. Due to legal issues with Universal, the events from Army of Darkness could not specifically be mentioned in the first season; it was later resolved and the events from that film were mentioned in the second season. In addition to Campbell, the series stars Dana DeLorenzo, Ray Santiago, and Lucy Lawless. ComicsArmy of Darkness had a comic book adaptation and several comic book sequels.

RUR-5 ASROC

The RUR-5 ASROC (for "Anti-Submarine Rocket") is an all-weather, all sea-conditions anti-submarine missile system. Developed by the United States Navy in the 1950s, it was deployed in the 1960s, updated in the 1990s, and eventually installed on over 200 USN surface ships, specifically cruisers, destroyers, and frigates. The ASROC has been deployed on scores of warships of many other navies, including Canada, Germany, Italy, Japan, the Republic of China, Greece, Pakistan and others. History ASROC started development as the Rocket Assisted Torpedo (RAT) program by the Naval Ordnance Test Station at China Lake in the early 1950s to develop a surface warship ASW weapon counter to the new post-World War II submarines which ran quieter, at much higher speed and could attack from much longer range with high speed homing torpedoes. In addition, the goal was to take advantage of modern sonars with a much larger detection range. An extended range torpedo delivered by parachute from the air would allow warships the stand-off capability to attack hostile submarines with very little advance notice to the hostile submarine. The RAT program came in three phases: RAT-A, RAT-B and RAT-C. RAT-A (and its follow-on, RAT-B) were efforts to develop a compact and economical stand-off ASW for smaller warships, but were found to be either unreliable or had too short a range. RAT-C was a program to develop a stand-off ASW weapon that used a nuclear depth charge. This would require a range of at least to escape potential damage from the underwater blast. Unlike the original RAT program rockets, the RAT-C was considerably larger to accomplish the extended range needed and was to be fitted to larger warships. With the failure of both the RAT-A and RAT-B programs, RAT-C was redesigned from a stand-off nuclear ASW weapon to one that could use not only a nuclear depth charge but also a homing ASW torpedo. To obtain the accuracy needed, the RAT-C rocket launcher had to be redesigned with larger side fins. This program finally combined reliability and accuracy, along with the necessary stand-off range. However, before RAT-C reached initial operational status in 1960 aboard the large US Navy destroyer leader , its name was changed to the present ASROC. ASROC was first deployed in 1961 and eventually made the vast majority of USN surface combatants nuclear-capable. Description The first ASROC system using the MK-112 "Matchbox" launcher was developed in the 1950s and installed in the 1960s. This system was phased out in the 1990s and replaced with the RUM-139 Vertical Launch ASROC, or "VLA". After a surface ship, patrol plane or anti-submarine helicopter detects an enemy submarine by using sonar or other sensors, it could relay the sub's position to an ASROC-equipped ship for attack. The attacking ship would then fire an ASROC missile carrying an acoustic homing torpedo or a W44 Nuclear Depth Bomb onto an unguided ballistic trajectory toward the target. At a pre-determined point on the missile's trajectory, the payload separates from the missile and deploys a parachute to permit splashdown and water entry at a low speed and with minimum detectable noise. Water entry activates the torpedo, which is guided by its own sonar system, and homes in on the target using either active sonar or passive sonar. W44 nuclear depth charge The W44 nuclear depth charge entered service in 1961, but was never used beyond one or two tests before the Limited Nuclear Test Ban Treaty banning underwater nuclear tests went into effect. A total of 575 weapons were produced. The W44 weighed with a diameter of and length of . Following payload separation, the unguided W44 sank quickly to a predetermined depth where the 10-kiloton warhead detonated. The nuclear-armed ASROC was never used in combat. W44-armed ASROC missiles were retired by 1989, when all types of nuclear depth bombs were removed from deployment. Specific installations One of the first ASROC installations was on in 1960. The first large group of ships to receive ASROC were 78 s, modified under the Fleet Rehabilitation and Modernization Mark I program (FRAM I) in the early 1960s. A Mark 112 8-tube ASROC launcher was added along with other major modifications. ASROC reloads were stowed alongside the helicopter hangar and handled by a small crane. The 31 U.S. Navy s were all built with the Mark 16 Mod 7 ASROC Launching Group and MK 4 ASROC Weapons Handling System (AWHS) reload system. These had one standard Mark 112 octuple ASROC launcher, located immediately above a reload system holding an additional 16 assembled rounds (two complete reloads of eight missiles apiece). Thus, each Spruance-class destroyer originally carried a maximum total of 24 ASROC. Most other US Navy and allied navy destroyers, destroyer escorts, frigates, and several different classes of cruisers only carried the one ASROC "matchbox" MK 112 launcher with eight ASROC missiles (although later in service, some of those missiles could be replaced by the Harpoon anti-ship missile). The "matchbox" Mk 112 launchers were capable of carrying a mixture of the two types. Reloads were carried in many classes, either on first level of the superstructure immediately abaft the launcher, or in a separate deckhouse just forward or abaft the Mk 112. The MK 16 Launching Group also had configurations that supported RGM-84 Harpoon (onboard destroyer escorts (frigates)) or a variation of the Tartar missile in limited distribution. Ships with the Mk 26 GMLS, and late marks of the Mk 10 GMLS aboard the s, could accommodate ASROC in these power-loaded launchers (the Mk 13 GMLS was not able to fire the weapon, as the launcher rail was too short). Most Spruance-class destroyers were later modified to include the Mk 41 VLS, these launchers are capable of carrying a mixture of the RUM-139 VL-ASROC, the Tomahawk TLAM, and other missiles. All of the Spruance destroyers carried two separate quad Harpoon launchers. Other US ships with the Mk 41 can also accommodate VL-ASROC. Operators Former operators - only on s (after IRE/DELEX modification.) - only on s - only on using a Mk 10 GMLS launcher (depot for 40 missiles, between RIM-2 Terrier / RIM-67A SM-1ER and ASROC) and - same configurations as US Navy were also deployed on some United States Coast Guard 378' (115 m) High Endurance Hamilton-class cutters during the 1970s and early 1980s.

Ahmed al-Nami

Ahmed bin Abdullah al-Nami (Arabic: أحمد بن عبد الله النعمي, ; also transliterated as Alnami; August 17, 1977 – September 11, 2001) was one of four terrorist hijackers of United Airlines Flight 93 as part of the September 11 attacks. Born in Saudi Arabia, al-Nami had served as a muezzin and was a college student. He left his family in 2000 to complete the Hajj, but later went to Afghanistan bound for an al-Qaeda training camp where he befriended other future hijackers and would soon be chosen to participate in the attacks. He arrived in the United States in May 2001, on a tourist visa, where he would settle in Florida up until the attacks. On September 11, 2001, al-Nami boarded United 93 and assisted in the hijacking of the plane so that it could be flown into either the U.S. Capitol or the White House. The plane instead crashed into a field in rural Somerset County, Pennsylvania during a passenger uprising, due to the passengers receiving information from their families of the three other hijacked planes that hit the World Trade Center and the Pentagon. Early life and activities Al-Nami, much like Wail al-Shehri, Waleed al-Shehri and Mohand al-Shehri, was born in the 'Asir Province in Saudi Arabia. Born to the Quraish tribe of Saudi Arabia, Al-Nami served as a muezzin at the Seqeley mosque after having reportedly become very religious sometime in early 1999. That autumn he left his family home in Abha in the summer of 2000 to complete the Hajj, but never returned – instead travelling to the Al Farouq training camp in Afghanistan where he met and befriended Waleed and Wail al-Shehri, two brothers from Khamis Mushayt in the same province, and Saeed al-Ghamdi. The four reportedly pledged themselves to Jihad in the Spring of 2000, in a ceremony presided over by Wail al-Shehri – who had dubbed himself Abu Mossaeb al-Janubi after one of Muhammad's companions. Dubbed "Abu Hashim", al-Nami was considered "gentle in manner" by his colleagues, and reported that he had a dream in which he rode a mare along with Muhammad, and that the prophet told him to dismount and fight his enemies to liberate his land. During his time at al-Farooq, there is a curious mention under Mushabib al-Hamlan's details that al-Nami had recently had laser eye surgery, an uncited fact that does not reappear. By October he had taken a prospective hijacker Mushabib al-Hamlan from Afghanistan to Saudi Arabia where they both procured B-1/B-2 tourist/business visas on October 28 – but al-Hamlan then decided not to proceed and is thought to have returned to his family. Al-Nami's visa application has since been reviewed, and while he mentioned that al-Hamlan will be travelling with him, he listed his occupation as student but failed to provide an address for his school, and listed his intended address in the United States merely as Los Angeles – in the end he never used this visa to enter the United States, and reported his passport (C115007, which showed evidence of travel to Afghanistan) as "lost", and procured a new one from Jeddah (C505363). He used the new passport to acquire a new B-1/B-2 visa in Jeddah on April 23, again recopying his answers from previously although crossing out the lines regarding al-Hamlan and previous attempts to acquire a visa. He was interviewed by a consular officer, who again approved his application. Records at the time only recorded past failures to procure a visa, so the officer had no way of realising that Nami had successfully received an earlier visa. In mid-November 2000, the 9/11 Commission believes that al-Nami, Wail and Waleed al-Shehri, all of whom had obtained their U.S. visas in late October, traveled in a group from Saudi Arabia to Beirut and then onward to Iran where they could travel through to Afghanistan without getting their passports stamped. This probably followed their return to Saudi Arabia to get "clean" passports. An associate of a senior Hezbollah operative is thought to have been on the same flight, although this may have been a coincidence. While in the United Arab Emirates, al-Nami purchased traveler's cheques presumed to have been paid for by Mustafa al-Hawsawi. Five other hijackers also passed through the UAE and purchased travellers cheques, including Majed Moqed, Saeed al-Ghamdi, Hamza al-Ghamdi, Ahmed al-Haznawi and Wail al-Shehri. 2001 In March 2001, Ahmed al-Nami appeared in an al-Qaeda farewell video showing 13 of the "muscle hijackers" before they left their training centre in Kandahar; while he does not speak, he is seen studying maps and flight manuals. On April 23, al-Nami was recorded obtaining a new US visa. On May 28, al-Nami arrived in the United States from Dubai with fellow-hijackers Mohand al-Shehri and Hamza al-Ghamdi. By early June, al-Nami was living in apartment 1504 at the Delray Racquet Club condominiums with Saeed al-Ghamdi in Delray Beach, Florida. He telephoned his family in 'Asir shortly after arriving in the country. In June, he phoned his family for the last time. He was one of 9 hijackers to open a SunTrust bank account with a cash deposit around June 2001, and on June 29 received either a Florida State Identification Card or Drivers License. He may have been one of three hijackers that listed the Naval Air Station in Pensacola, Florida as their permanent address on drivers' licenses, though other sources claim he listed the Delray condominium. On August 28, al-Nami and Ahmed al-Haznawi reportedly bothered a Delray Beach resident, Maria Siscar Simpson, to let them through her apartment to retrieve a towel that had fallen off their balcony onto hers. On September 5, al-Nami and Saeed al-Ghamdi purchased tickets for a September 7 flight to Newark at Mile High Travel on Commercial Boulevard—paying cash for their tickets. Ziad Jarrah and Ahmed al-Haznawi also purchased tickets for the same flight from Passage Tours. On September 7, all four Flight 93 hijackers flew from Fort Lauderdale to Newark International Airport aboard Spirit Airlines. Attacks On September 11, 2001, Nami arrived in Newark to board United Airlines Flight 93 along with Saeed al-Ghamdi, Ahmed al-Haznawi and Ziad Jarrah. Some reports suggest Haznawi was pulled aside for screening while others claim there is no record of whether any of the four were screened; the lack of CCTV cameras at the time has compounded the problem. Nami boarded the plane between 7:39 am and 7:48 am; seated in First Class 3C, next to Saeed al-Ghamdi. Due to the flight's routine delay, the pilot and crew were notified of the previous hijackings and were told to be on the alert, though within two minutes Jarrah had stormed the cockpit leaving the pilots dead or injured. At least two of the cellphone calls made by passengers indicate that all the hijackers they saw were wearing red bandanas, which some have questioned may have signified an allegiance to the Egyptian Islamic Jihad. The calls also indicated that one of the men had tied a box around his torso, and claimed there was a bomb inside; it is not known which hijacker this was. Passengers on the plane heard through phone calls the fates of the other hijacked planes, and organized a brief assault to retake the cockpit. Three times in a period of five seconds there were shouts of pain or distress from a hijacker outside the cockpit, suggesting that Nami was being attacked by the passengers. The hijackers crashed the plane into the Pennsylvanian countryside rather than cede control of the plane. All aboard died. Aftermath He has been portrayed by British actor Jamie Harding in the 2006 film United 93 and Asim Wali in the film Flight 93.

Ahmed al-Haznawi

Ahmed Ibrahim al-Haznawi al-Ghamdi (, ) (October 11, 1980 – September 11, 2001) was one of four terrorist hijackers of United Airlines Flight 93 as part of the September 11 attacks. He left his family to fight in Chechnya in 2000 but was probably sent to training camps in Afghanistan. It was there he was chosen to participate in the 9/11 attacks. He arrived in the United States in June 2001 under the direction of Al-Qaeda for terrorist attacks, on a tourist visa. Once he was in the U.S., he settled in Florida and helped plan out how the attacks would take place. On September 11, 2001, al-Haznawi boarded United Airlines Flight 93 and assisted in the hijacking of the plane so it could be crashed into either the U.S. Capitol or the White House. Instead, the plane crashed into a field in Somerset County, Pennsylvania, after the passengers on-board started a revolt against al-Haznawi and the other hijackers. Early life Ahmed al-Haznawi was the son of a Saudi imam from the Al-Bahah province, a province in the south west of Saudi Arabia. Al-Haznawi grew up in the village of Hazna, where his father was a cleric at the mosque in the central marketplace section of the village. Al-Haznawi belonged to a family that was part of the larger Ghamd tribe, sharing the same tribal affiliation with fellow hijackers Saeed al-Ghamdi, Hamza al-Ghamdi, and Ahmed al-Ghamdi. He memorised the Quran, giving him the title Hafiz. This group is noted as being some of the more religiously observant of the hijackers, and they are thought to have met one another some time in 1999. Early activities 1999–2000 Al-Haznawi announced he was leaving his family in 1999 to fight in Chechnya, although his father forbade him. His father and brother, Abdul Rahman al-Haznawi, reportedly last heard from him in late 2000, after he made references to training in Afghanistan. On November 12, 2000, al-Haznawi applied for and received a two-year U.S. B-1/B-2 (tourist/business) visa in Jeddah, Saudi Arabia. From November 27, 2000, through December 27, 2000, al-Haznawi was in Saudi Arabia for Ramadan. It is theorized that during this trip, he may have initially told Saeed and Hamza al-Ghamdi about the operation. Some time late in 2000, al-Haznawi traveled to the United Arab Emirates, where he purchased traveler's cheques presumed to have been paid for by Mustafa al-Hawsawi. Five other hijackers also passed through the UAE and purchased travellers cheques, including Majed Moqed, Saeed al-Ghamdi, Hamza al-Ghamdi, Wail al-Shehri and Ahmed al-Nami. 2001 He was one of four hijackers believed to be staying at a Kandahar guest house in March 2001, where they were seen by Mohammed Jabarah. Jabarah remembered al-Haznawi specifically, saying that he was "very devout and could recite the entire Koran from memory." On June 8, he arrived in Miami, Florida, with fellow hijacker Wail al-Shehri. He was one of 9 hijackers to open a SunTrust bank account with a cash deposit around June 2001. He is believed to have moved in with Ziad Jarrah, who got a new apartment on Bougainvilla Dr. in Lauderdale-by-the-Sea, after both men gave the landlord photocopies of their German passports, which he later turned over to the FBI. On June 25, Jarrah took al-Haznawi to Holy Cross Hospital in Fort Lauderdale on advice of his landlord Charles Lisa. Al-Haznawi was treated by Dr. Christos Tsonas, who gave him antibiotics for a small gash on his left calf. While he told staff that he had bumped into a suitcase, the media briefly reported it as a sign of cutaneous anthrax and a possible link to the 2001 anthrax attacks, although FBI later addressed the rumors stating that "Exhaustive testing did not support that anthrax was present anywhere the hijackers had been." On July 10, al-Haznawi obtained a Florida driver's license, later obtaining another copy on September 7, 2001, by filling out a change-of-address form. Five other hijackers also received duplicate Florida licenses in 2001, and others had licenses from different states. Some have speculated that this was to allow multiple persons to use the same identity. Jarrah and al-Haznawi both received their one-way tickets for United Airlines Flight 93, on September 5. On September 7, all four Flight 93 hijackers flew from Fort Lauderdale to Newark International Airport aboard Spirit Airlines. Attacks On September 11, 2001, al-Haznawi arrived at Newark International Airport to board United Airlines Flight 93. Although he was selected for additional security by CAPPS and screened, he was able to board the flight without incident, with only his checked bags requiring extra screening for explosives. Due to the flight's delay, the pilot and crew were notified of the previous hijackings that day and were told to be on the alert. Within minutes, Flight 93 was hijacked as well. At least two of the cellphone calls made by passengers indicate that all the hijackers they saw were wearing red bandanas, which some believe may have signified an allegiance to the Egyptian Islamic Jihad. The calls also indicated that one of the men had tied a box around his torso, and claimed there was a bomb inside – it is not known which hijacker this was. Some passengers expressed doubt that the bomb was real. Passengers on the plane heard through phone calls the fates of the other hijacked planes. A passenger uprising soon took place. Hijacker-pilot, Ziad Jarrah, crashed the plane into an empty field near Shanksville, Pennsylvania, in order to prevent the passengers from gaining control of the plane. The crash killed everyone on board. Aftermath After the attacks, before the release of the FBI pictures of the hijackers, Arab News reported that al-Haznawi's brother Abdul Rahman had told al-Madinah newspaper that a photograph published by local newspapers bore no resemblance to his brother. A videotape titled "The Wills of the New York and Washington Battle Martyrs" was aired on Al Jazeera on April 16, 2002. While the name beneath the speaker read al-Ghamdi, the image is of al-Haznawi speaking. Officials suggested that the name was merely a reference to his tribal affiliation. The film was thought to have been made in March 2001. In it, he talked about his plans to bring the "bloodied message" to America. In September 2002, a similar tape made by Abdulaziz al-Omari appeared. He has been portrayed by actors Omar Berdouni in United 93, and Zak Santiago in Flight 93.

Athanasius of Alexandria

Athanasius I of Alexandria (c. 296–298 – 2 May 373), also called Athanasius the Great, Athanasius the Confessor or, primarily in the Coptic Orthodox Church, Athanasius the Apostolic, was a Greek church father and the 20th bishop of Alexandria (as Athanasius I). His intermittent episcopacy spanned 45 years (c. 8 June 328 – 2 May 373), of which over 17 encompassed five exiles, when he was replaced on the order of four different Roman emperors. Athanasius was a Christian theologian, a Church Father, the chief defender of Trinitarianism against Arianism, and a noted Coptic Christian (Egyptian) leader of the fourth century. Conflict with Arius and Arianism as well as successive Roman emperors shaped Athanasius' career. In 325, at the age of 27, Athanasius began his leading role against the Arians as a deacon and assistant to Bishop Alexander of Alexandria during the First Council of Nicaea. Roman emperor Constantine the Great had convened the council in May–August 325 to address the Arian position that the Son of God, Jesus of Nazareth, is of a distinct substance from the Father. Three years after that council, Athanasius succeeded his mentor as archbishop of Alexandria. In addition to the conflict with the Arians (including powerful and influential Arian churchmen led by Eusebius of Nicomedia), he struggled against the Emperors Constantine, Constantius II, Julian the Apostate and Valens. He was known as Athanasius Contra Mundum (Latin for Athanasius Against the World). Nonetheless, within a few years of his death, Gregory of Nazianzus called him the "Pillar of the Church". His writings were well regarded by subsequent Church fathers in the West and the East, who noted their devotion to the Word-become-man, pastoral concern and interest in monasticism. Athanasius is considered one of the four great Eastern Doctors of the Church in the Catholic Church. In his Easter letter of 367, Athanasius was the first person to list the 27 books of the New Testament canon that is in use today. He is venerated as a Saint in the Eastern Orthodox Church, the Catholic Church, the Coptic Orthodox Church, the Anglican Communion, and Lutheranism. Biography Athanasius was born to a Christian family in the city of Alexandria or possibly the nearby Nile Delta town of Damanhur sometime between the years 293 and 298. The earlier date is sometimes assigned due to the maturity revealed in his two earliest treatises Contra Gentes (Against the Heathens) and De Incarnatione (On the Incarnation), which were admittedly written about the year 318 before Arianism had begun to make itself felt, as those writings do not show an awareness of Arianism. However Cornelius Clifford places his birth no earlier than 296 and no later than 298, based on the fact that Athanasius indicates no first hand recollection of the Maximian persecution of 303, which he suggests Athanasius would have remembered if he had been ten years old at the time. Secondly, the Festal Epistles state that the Arians had accused Athanasius, among other charges, of not having yet attained the canonical age (35) and thus could not have been properly ordained as Patriarch of Alexandria in 328. The accusation must have seemed plausible. The Orthodox Church places his year of birth around 297. Education His parents were wealthy enough to give him a fine secular education. He was, nevertheless, clearly not a member of the Egyptian aristocracy. Some Western scholars consider his command of Greek, in which he wrote most (if not all) of his surviving works, evidence that he may have been a Greek born in Alexandria. Historical evidence, however, indicates that he was fluent in Coptic as well given the regions of Egypt where he preached. Some surviving copies of his writings are in fact in Coptic, though scholars differ as to whether he himself wrote them in Coptic originally (which would make him the first patriarch to do so), or whether these were translations of writings originally in Greek. Rufinus relates a story that as Bishop Alexander stood by a window, he watched boys playing on the seashore below, imitating the ritual of Christian baptism. He sent for the children and discovered that one of the boys (Athanasius) had acted as bishop. After questioning Athanasius, Bishop Alexander informed him that the baptisms were genuine, as both the form and matter of the sacrament had been performed through the recitation of the correct words and the administration of water, and that he must not continue to do this as those baptized had not been properly catechized. He invited Athanasius and his playfellows to prepare for clerical careers. Alexandria was the most important trade centre in the whole empire during Athanasius's boyhood. Intellectually, morally, and politically—it epitomized the ethnically diverse Graeco-Roman world, even more than Rome or Constantinople, Antioch or Marseilles. Its famous catechetical school, while sacrificing none of its famous passion for orthodoxy since the days of Pantaenus, Clement of Alexandria, Origen of Alexandria, Dionysius and Theognostus, had begun to take on an almost secular character in the comprehensiveness of its interests, and had counted influential pagans among its serious auditors. Peter of Alexandria, the 17th archbishop of Alexandria, was martyred in 311 in the closing days of the persecution, and may have been one of those teachers. His successor as bishop of Alexandria was Alexander of Alexandria (312–328). According to Sozomen; "the Bishop Alexander 'invited Athanasius to be his commensal and secretary. He had been well educated, and was versed in grammar and rhetoric, and had already, while still a young man, and before reaching the episcopate, given proof to those who dwelt with him of his wisdom and acumen' ".(Soz., II, xvii) Athanasius' earliest work, Against the Heathen – On the Incarnation (written before 319), bears traces of Origenist Alexandrian thought (such as repeatedly quoting Plato and using a definition from Aristotle's Organon) but in an orthodox way. Athanasius was also familiar with the theories of various philosophical schools, and in particular with the developments of Neo-Platonism. Ultimately, Athanasius would modify the philosophical thought of the School of Alexandria away from the Origenist principles such as the "entirely allegorical interpretation of the text". Still, in later works, Athanasius quotes Homer more than once (Hist. Ar. 68, Orat. iv. 29). Athanasius knew Greek and admitted not knowing Hebrew [see, e.g., the 39th Festal Letter of St. Athan.]. The Old Testament passages he quotes frequently come from the Septuagint Greek translation. Only rarely did he use other Greek versions (to Aquila once in the Ecthesis, to other versions once or twice on the Psalms), and his knowledge of the Old Testament was limited to the Septuagint. The combination of Scriptural study and of Greek learning was characteristic of the famous Alexandrian School. Bishop (or Patriarch, the highest ecclesial rank in the Centre of the Church, in Alexandria) Alexander ordained Athanasius a deacon in 319. In 325, Athanasius served as Alexander's secretary at the First Council of Nicaea. Already a recognized theologian and ascetic, he was the obvious choice to replace his ageing mentor Alexander as the Patriarch of Alexandria, despite the opposition of the followers of Arius and Meletius of Lycopolis. At length, in the Council of Nicaea, the term "consubstantial" (homoousios) was adopted, and a formulary of faith embodying it was drawn up by Hosius of Córdoba. From this time to the end of the Arian controversies the word "consubstantial" continued to be the test of orthodoxy. The formulary of faith drawn up by Hosius is known as the Nicene Creed. However, "he was not the originator of the famous 'homoousion' (ACC of homoousios). The term had been proposed in a non-obvious and illegitimate sense by Paul of Samosata to the Fathers at Antioch, and had been rejected by them as savouring of materialistic conceptions of the Godhead." While still a deacon under Alexander's care (or early in his patriarchate as discussed below) Athanasius may have also become acquainted with some of the solitaries of the Egyptian desert, and in particular Anthony the Great, whose life he is said to have written. Opposition to Arianism In about 319, when Athanasius was a deacon, a presbyter named Arius came into a direct conflict with Alexander of Alexandria. It appears that Arius reproached Alexander for what he felt were misguided or heretical teachings being taught by the bishop. Arius' theological views appear to have been firmly rooted in Alexandrian Christianity. He embraced a subordinationist Christology which taught that Christ was the divine Son (Logos) of God, made, not begotten, heavily influenced by Alexandrian thinkers like Origen, and which was a common Christological view in Alexandria at the time. Arius had support from a powerful bishop named Eusebius of Nicomedia (not to be confused with Eusebius of Caesarea), illustrating how Arius's subordinationist Christology was shared by other Christians in the Empire. Arius was subsequently excommunicated by Alexander, and he would begin to elicit the support of many bishops who agreed with his position. Patriarch Frances A. M. Forbes writes that when the Patriarch Alexander was on his death-bed he called Athanasius, who fled fearing he would be constrained to be made bishop. "When the Bishops of the Church assembled to elect their new Patriarch, the whole Catholic population surrounded the church, holding up their hands to Heaven and crying; "Give us Athanasius!" The Bishops had nothing better. Athanasius was thus elected, as Gregory tells us..." (Pope Gregory I, would have full access to the Vatican Archives). T. Gilmartin, (Professor of History, Maynooth, 1890), writes in Church History, Vol. 1, Ch XVII: "On the death of Alexander, five months after the termination of the Council of Nicaea, Athanasius was unanimously elected to fill the vacant see. He was most unwilling to accept the dignity, for he clearly foresaw the difficulties in which it would involve him. The clergy and people were determined to have him as their bishop, Patriarch of Alexandria, and refused to accept any excuses. He at length consented to accept a responsibility that he sought in vain to escape, and was consecrated in 326, when he was about thirty years of age." Athanasius' episcopate began on 9 May 328 as the Alexandrian Council elected Athanasius to succeed after the death of Alexander, and was consecrated in A.D. 326.". Patriarch Athanasius spent over 17 years in five exiles ordered by four different Roman Emperors, not counting approximately six more incidents in which Athanasius fled Alexandria to escape people seeking to take his life. During his first years as bishop, Athanasius visited the churches of his territory, which at that time included all of Egypt and Libya. He established contacts with the hermits and monks of the desert, including Pachomius, which proved very valuable to him over the years. "During the forty-eight years of his episcopate, his history is told in the history of the controversies in which he was constantly engaged with the Arians, and of the sufferings he had to endure in defence of the Nicene faith. We have seen that when Arius was allowed to return from exile in 328, Athanasius refused to remove the sentence of excommunication." First exile Athanasius' first problem lay with Meletius of Lycopolis and his followers, who had failed to abide by the First Council of Nicaea. That council also anathematized Arius. Accused of mistreating Arians and Meletians, Athanasius answered those charges at a gathering of bishops in Tyre, the First Synod of Tyre, in 335. There, Eusebius of Nicomedia and other supporters of Arius deposed Athanasius. On 6 November, both sides of the dispute met with Emperor Constantine I in Constantinople. At that meeting, the Arians claimed Athanasius would try to cut off essential Egyptian grain supplies to Constantinople. He was found guilty, and sent into exile to Augusta Treverorum in Gaul (now Trier in Germany). When Athanasius reached his destination in exile in 336, Maximin of Trier received him, but not as a disgraced person. Athanasius stayed with him for two years. Constantine died in 337 and was succeeded by his three sons, Constantine II, Constantius, and Constans. Paul I of Constantinople, who had also been banished by Constantius, also found shelter with Maximin, who cautioned the Emperor Constans against the Arians, revealing their plots. Second exile When Emperor Constantine I died, Athanasius was allowed to return to his See of Alexandria. Shortly thereafter, however, Constantine's son, the new Roman Emperor Constantius II, renewed the order for Athanasius's banishment in 338. 'Within a few weeks he set out for Rome to lay his case before the Church at large. He had made his appeal to Pope Julius, who took up his cause with whole-heartedness that never wavered down to the day of that holy pontiff's death. The pope summoned a synod of bishops to meet in Rome. After a careful and detailed examination of the entire case, the primate's innocence was proclaimed to the Christian world.'. During this time, Gregory of Cappadocia, an Arian bishop, was installed as the Patriarch of Alexandria, usurping the absent Athanasius. Athanasius did, however, remain in contact with his people through his annual Festal Letters, in which he also announced on which date Easter would be celebrated that year. In 339 or 340, nearly one hundred bishops met at Alexandria, declared in favour of Athanasius, and vigorously rejected the criticisms of the Eusebian faction at Tyre. Plus, Pope Julius I wrote to the supporters of Arius strongly urging Athanasius's reinstatement, but that effort proved in vain. Pope Julius I called a synod in Rome in 340 to address the matter, which proclaimed Athanasius the rightful bishop of Alexandria. Early in the year 343 we find Athanasius had travelled, via Rome, from Alexandria, North Africa, to Gaul; nowadays Belgium / Holland and surrounding areas, where Hosius of Córdoba was bishop, the great champion of orthodoxy in the West. Together they set out for Serdica. A full Council of the Church was convened / summoned there in deference to the Roman pontiff's wishes. The travel was a mammoth task in itself. At this great gathering of prelates, leaders of the Church, the case of Athanasius was taken up once more, that is, Athanasius was formally questioned over misdemeanours and even murder, (a man called Arsenius and using his body for magic – an absurd charge. They even produced Arsenius' severed hand.) The Council was convoked for the purpose of inquiring into the charges against Athanasius and other bishops, on account of which they were deposed from their sees by the Semi-Arian Synod of Antioch (341), and went into exile. It was called according to Socrates, (E. H. ii. 20) by the two Emperors, Constans and Constantius; but, according to Baronius by Pope Julius (337–352), (Ad an. 343). One hundred and seventy six attended. Eusebian bishops objected to the admission of Athanasius and other deposed bishops to the Council, except as accused persons to answer the charges brought against them. Their objections were overridden by the orthodox bishops, about a hundred were orthodox, who were the majority. The Eusebians, seeing they had no chance of having their views carried, retired to Philoppopolis in Thrace, where they held an opposition council, under the presidency of the Patriarch of Antioch, and confirmed the decrees of the Synod of Antioch. Athanasius' innocence was reaffirmed at the Council of Serdica. Two conciliar letters were prepared, one to the clergy and faithful of Alexandria, the other to the bishops of Egypt and Libya, in which the will of the Council was made known. Meanwhile, the Eusebian party had gone to Philippopolis, where they issued an anathema against Athanasius and his supporters. The persecution against the orthodox party broke out with renewed vigour, and Constantius was induced to prepare drastic measures against Athanasius and the priests who were devoted to him. Orders were given that if Athanasius attempted to re-enter his see, he should be put to death. Athanasius, accordingly, withdrew from Serdica to Naissus in Mysia, where he celebrated the Easter festival of the year 344. It was Hosius who presided over the Council of Serdica, as he did for the First Council of Nicaea, which like the 341 synod, found Athanasius innocent. He celebrated his last Easter in exile in Aquileia in April 345, received by bishop Fortunatianus. Eastern Bishop Gregory of Cappadocia died, probably of violence in June of 345. The emissary to the Emperor Constantius sent by the bishops of the Council of Serdica to report the finding of the Council, who had been met at first with most insulting treatment, now received a favourable hearing. Constantius was forced to reconsider his decision, owing to a threatening letter from his brother Constans and the uncertain conditions of affairs on the Persian border, and he accordingly made up his mind to yield. But three separate letters were needed to overcome the natural hesitation of Athanasius. He passed rapidly from Aquileia to Treves, from Treves to Rome and from Rome by way of the northern route to Adrianople, Edirne, and Antioch, Ankara, where he met Constantius. He was accorded a gracious interview by the Emperor, and sent back to his See in triumph, and began his memorable ten years of peace, which lasted to the third exile, 356. Pope Julius died in April 352, and was succeeded by Liberius. For two years Liberius had been favourable to the cause of Athanasius; but driven at last into exile, he was induced to sign an ambiguous formula, from which the great Nicene text, the "homoousion", had been studiously omitted. In 355 a council was held at Milan, where in spite of the vigorous opposition of a handful of loyal prelates among the Western bishops, a fourth condemnation of Athanasius was announced to the world. With his friends scattered, Hosius in exile, and Pope Liberius denounced as acquiescing in Arian formularies, Athanasius could hardly hope to escape. On the night of 8 February 356, while engaged in services in the Church of St. Thomas, a band of armed men burst in to secure his arrest. It was the beginning of his third exile. T. Gilmartin, (Professor of History, Maynooth, 1890), writes in Church History, Vol. 1, Ch XVII: By Constantius' order, the sole ruler of The Roman Empire at the death of his brother Constans, the Council of Arles in 353, was held, which was presided over by Vincent, Bishop of Capua, in the name of Pope Liberius. The fathers terrified of the threats of the Emperor, an avowed Arian, they consented to the condemnation of Athanasius. The Pope refused to accept their decision, and requested the Emperor to hold another Council, in which the charges against Athanasius could be freely investigated. To this Constantius consented, for he felt able to control the Council in Milan. Three hundred bishops assembled in Milan, most from the West, only a few from the East, in 355. They met in the Church of Milan. Shortly, the Emperor ordered them to a hall in the Imperial Palace, thus ending any free debate. He presented an Arian formula of faith for their acceptance. He threatened any who refused with exile and death. All, with the exception of Dionysius (bishop of Milan), and the two Papal Legates, viz., Eusebius of Vercelli and Lucifer of Cagliari, consented to the Arian Creed and the condemnation of Athanasius. Those who refused were sent into exile. The decrees were forwarded to the Pope for approval, but were rejected, because of the violence to which the bishops were subjected. Third exile Through the influence of the Eusebian faction at Constantinople, an Arian bishop, George of Cappadocia, was now appointed to rule the see of Alexandria. Athanasius, after remaining some days in the neighbourhood of the city, finally withdrew into the desert of Upper Egypt, where he remained for a period of six years, living the life of the monks, devoting himself to the composition of a group of writings; "Apology to Constantius", the "Apology for his Flight", the "Letter to the Monks", and the "History of the Arians". Constantius, renewing his previous policies favouring the Arians, banished Athanasius from Alexandria once again. This was followed, in 356, by an attempt to arrest Athanasius during a vigil service. Athanasius fled to Upper Egypt, where he stayed in several monasteries and other houses. During this period, Athanasius completed his work Four Orations against the Arians and defended his own recent conduct in the Apology to Constantius and Apology for His Flight. Constantius' persistence in his opposition to Athanasius, combined with reports Athanasius received about the persecution of non-Arians by the new Arian bishop George of Laodicea, prompted Athanasius to write his more emotional History of the Arians, in which he described Constantius as a precursor of the Antichrist. Constantius ordered Liberius into exile in 356 giving him three days to comply. He was ordered into banishment to Beroea, in Thrace. He sent expensive presents if he were to accept the Arian position, which Liberius refused. He sent him five hundred pieces of gold "to bear his charges" which Liberius refused, saying he might bestow them on his flatterers; as he did also a like present from the empress, bidding the messenger learn to believe in Christ, and not to persecute the Church of God. Attempts were made to leave the presents in The Church, but Liberius threw them out. Constantius hereupon sent for him under a strict guard to Milan, where in a conference recorded by Theodore, he boldly told Constantius that Athanasius had been acquitted at Serdica, and his enemies proved calumniators (see: "calumny") and impostors, and that it was unjust to condemn a person who could not be legally convicted of any crime. The emperor was reduced to silence on every article, but being the more out of patience, ordered him into banishment. Liberius went into exile. Constantius, after two years went to Rome to celebrate the twentieth year of his reign. The ladies joined in a petition to him that he would restore Liberius. He assented, upon condition that he should comply with the bishops, then, at court. He subscribed the condemnation of Athanasius, and a confession or creed which had been framed by the Arians at Sirmium. And he no sooner had recovered his see that he declared himself for the Creed of Niceae, as Theodoret testifies. (Theodoret, Hist. lib. ii. c. 17.). The Emperor knew what he wanted people to believe. So did the bishops at his court. Athanasius stuck by the orthodox creed. Constantius was an avowed Arian, became sole ruler in 350, at the death of his brother, Constans. T. Gilmartin, (Professor of History, Maynooth, 1890), writes in Church History, Vol. 1, Ch XVII: The Arians sought the approval of an Ecumenical Council. They sought to hold two councils. Constantius, summoned the bishops of the East to meet at Seleucia in Isauria, and those of the West to Rimini in Italy. A preliminary conference was held by the Arians at Sirmium, to agree a formula of faith. A "Homoeon" creed was adopted, declaring The Son to be "like the Father". The two met in autumn of 359. At Seleucia, one hundred and fifty bishops, of which one hundred and five were semi-Arian. The semi-Arians refused to accept anything less than the "Homoiousion", (see: Homoiousian), formulary of faith. The Imperial Prefect was obliged to disband, without agreeing on any creed. Acacius, the leader of the "Homoean" party went to Constantinople, where the Sirmian formulary of faith was approved by the "Home Synod", (consisted of those bishops who happened to be present at the Court for the time), and a decree of deposition issued against the leaders of the semi-Arians. At Rimini were over four hundred of which eighty were Arian, the rest were orthodox. The orthodox fathers refused to accept any creed but the Nicene, while the others were equally in favour of the Sirmian. Each party sent a deputation to the Emperor to say there was no probability to agreement, and asked for the bishops to return to their dioceses. For the purpose of wearing-down the orthodox bishops; (Sulpitius Severius says), Constantius delayed his answer for several months, and finally prevailed on them to accept the Sirmian creed. It was after this Council that Jerome said: " ...the whole world groaned in astonishment to find itself Arian." The Arians no longer presented an unbroken front to their orthodox opponents. The Emperor Constantius, who had been the cause of so much trouble, died on 4 November 361 and was succeeded by Julian. The proclamation of the new prince's accession was the signal for a pagan outbreak against the still dominant Arian faction in Alexandria. George, the usurping bishop, was flung into prison and murdered. An obscure presbyter of the name of Pistus was immediately chosen by the Arians to succeed him, when fresh news arrived that filled the orthodox party with hope. An edict had been put forth by Julian permitting the exiled bishops of the "Galileans" to return to their "towns and provinces". Athanasius received a summons from his own flock, and he accordingly re-entered his episcopal capitol on 22 February 362. In 362 he convened a council at Alexandria, and presided over it with Eusebius of Vercelli. Athanasius appealed for unity among all those who had faith in Christianity, even if they differed on matters of terminology. This prepared the groundwork for his definition of the orthodox doctrine of the Trinity. However, the council also was directed against those who denied the divinity of the Holy Spirit, the human soul of Christ, and Christ's divinity. Mild measures were agreed on for those heretic bishops who repented, but severe penance was decreed for the chief leaders of the major heresies. With characteristic energy he set to work to re-establish the somewhat shattered fortunes of the orthodox party and to purge the theological atmosphere of uncertainty. To clear up the misunderstandings that had arisen in the course of the previous years, an attempt was made to determine still further the significance of the Nicene formularies. In the meanwhile, Julian, who seems to have become suddenly jealous of the influence that Athanasius was exercising at Alexandria, addressed an order to Ecdicius, the Prefect of Egypt, peremptorily commanding the expulsion of the restored primate, on the ground that he had never been included in the imperial act of clemency. The edict was communicated to the bishop by Pythicodorus Trico, who, though described in the "Chronicon Athanasianum" (XXXV) as a "philosopher", seems to have behaved with brutal insolence. On 23 October the people gathered about the proscribed bishop to protest against the emperor's decree; but Athanasius urged them to submit, consoling them with the promise that his absence would be of short duration. Fourth exile In 362, the new Emperor Julian, noted for his opposition to Christianity, ordered Athanasius to leave Alexandria once again. Athanasius left for Upper Egypt, remaining there with the Desert Fathers until Julian's death on 26 June 363. Athanasius returned in secret to Alexandria, where he soon received a document from the new emperor, Jovian, reinstating him once more in his episcopal functions. His first act was to convene a council which reaffirmed the terms of the Nicene Creed. Early in September 363 he set out for Antioch on the Orontes, bearing a synodal letter, in which the pronouncements of this council had been embodied. At Antioch he had an interview with the new emperor, who received him graciously and even asked him to prepare an exposition of the orthodox faith. The following February Jovian died; and in October, 364, Athanasius was once more an exile. Fifth exile Two years later, the Emperor Valens, who favoured the Arian position, in his turn exiled Athanasius. This time Athanasius simply left for the outskirts of Alexandria, where he stayed for only a few months before the local authorities convinced Valens to retract his order of exile. Some early reports state that Athanasius spent this period of exile at his family's ancestral tomb in a Christian cemetery. It was during this period, the final exile, that he is said to have spent four months in hiding in his father's tomb. (Soz., "Hist. Eccl.", VI, xii; Soc., "Hist. Eccl.", IV, xii). The accession of Valens gave a fresh lease of life to the Arian party. He issued a decree banishing the bishops who had been deposed by Constantius, but who had been permitted by Jovian to return to their sees. The news created the greatest consternation in the city of Alexandria itself, and the prefect, in order to prevent a serious outbreak, gave public assurance that the very special case of Athanasius would be laid before the emperor. But Athanasius seems to have divined what was preparing in secret against him. He quietly withdrew from Alexandria, 5 October, and took up his abode in a country house outside the city. Valens, who seems to have sincerely dreaded the possible consequences of another popular outbreak, within a few weeks issued orders allowing Athanasius to return to his episcopal see. In 366 Pope Liberius died and was succeeded by Pope Damasus, a man of strong character and holy life. Two years later, in a council of the Church, it was decreed that no Bishop should be consecrated unless he held the Creed of Nicea. (F. A. Forbes). Final years and death After returning to Alexandria in early 366, Athanasius spent his final years repairing all the damage done during the earlier years of violence, dissent, and exile. He resumed writing and preaching undisturbed, and characteristically re-emphasized the view of the Incarnation which had been defined at Nicaea. On 2 May 373, having consecrated Peter II, one of his presbyters as his successor, Athanasius died peacefully in his own bed, surrounded by his clergy and faithful supporters. Works In Coptic literature, Athanasius is the first patriarch of Alexandria to use Coptic as well as Greek in his writings. Polemical and theological works Athanasius was not a speculative theologian. As he stated in his First Letters to Serapion, he held on to "the tradition, teaching, and faith proclaimed by the apostles and guarded by the fathers." He held that not only was the Son of God consubstantial with the Father, but so was the Holy Spirit, which had a great deal of influence in the development of later doctrines regarding the Trinity. Athanasius' "Letter Concerning the Decrees of the Council of Nicaea" (De Decretis), is an important historical as well as theological account of the proceedings of that council, and another letter from 367 is the first known listing of all those books now accepted as the New Testament. (Earlier similar lists vary by the omission or addition of a few books.) Examples of Athanasius' polemical writings against his theological opponents include Orations Against the Arians, his defence of the divinity of the Holy Spirit (Letters to Serapion in the 360s, and On the Holy Spirit), against Macedonianism and On the Incarnation. Athanasius also authored a two-part work, Against the Heathen and The Incarnation of the Word of God. Completed probably early in his life, before the Arian controversy, they constitute the first classic work of developed Orthodox theology. In the first part, Athanasius attacks several pagan practices and beliefs. The second part presents teachings on the redemption. Also in these books, Athanasius put forward the belief, referencing , that the Son of God, the eternal Word (Logos) through whom God created the world, entered that world in human form to lead men back into the harmony from which they had earlier fallen away. His other important works include his Letters to Serapion, which defends the divinity of the Holy Spirit. In a letter to Epictetus of Corinth, Athanasius anticipates future controversies in his defence of the humanity of Christ. Another of his letters, to Dracontius, urges that monk to leave the desert for the more active duties of a bishop. Athanasius also wrote several works of Biblical exegesis, primarily on Old Testament materials. The most important of these is his Epistle to Marcellinus (PG 27:12–45) on how to incorporate Psalm saying into one's spiritual practice. Excerpts remain of his discussions concerning the Book of Genesis, the Song of Solomon, and Psalms. Perhaps his most notable letter was his Festal Letter, written to his Church in Alexandria when he was in exile, as he could not be in their presence. This letter clearly shows his stand that accepting Jesus as the Divine Son of God is not optional but necessary: Biographical and ascetic His biography of Anthony the Great entitled Life of Antony(Βίος καὶ Πολιτεία Πατρὸς Ἀντωνίου, Vita Antonii) became his most widely read work. Translated into several languages, it became something of a best seller in its day and played an important role in the spreading of the ascetic ideal in Eastern and Western Christianity. It depicted Anthony as an illiterate yet holy man who continuously engaged in spiritual exercises in the Egyptian desert and struggled against demonic powers. It later served as an inspiration to Christian monastics in both the East and the West. Athanasius' works on asceticism also include a Discourse on Virginity, a short work on Love and Self-Control, and a treatise On Sickness and Health (of which only fragments remain). Misattributed works There are several other works ascribed to him, although not necessarily generally accepted as being his own. These include the so-called Athanasian creed (which is today generally seen as being of 5th-century Galician origin), and a complete Expositions on the Psalms (PG 27: 60–545). Eschatology Based on his understanding of the prophecies of Daniel and Book of Revelation, Athanasius described Jesus’ second coming in the clouds of heaven and pleads with his readers to be ready for that day, at which time Jesus would judge the earth, raise the dead, cast out the wicked, and establish his kingdom. Athanasius also argued that the exact date of Jesus’ earthly sojourn was divinely foretold beyond refutation by the seventy weeks prophecy of Daniel 9. Veneration Athanasius was originally buried in Alexandria, Egypt, but his remains were later transferred to the Chiesa di San Zaccaria in Venice, Italy. During Pope Shenouda III's visit to Rome (4–10 May 1973), Pope Paul VI gave the Coptic Patriarch a relic of Athanasius, which he brought back to Egypt on 15 May. The relic is currently preserved under the new Saint Mark's Coptic Orthodox Cathedral in Cairo, Egypt. However, the majority of Athanasius's corpse remains in the Venetian church. All major Christian denominations which officially recognize saints venerate Athanasius. Western Christians observe his feast day on 2 May, the anniversary of his death. The Catholic Church considers Athanasius a Doctor of the Church. For Coptic Christians, his feast day is Pashons 7 (now circa 15 May). Eastern Orthodox liturgical calendars remember Athanasius on 18 January. Gregory of Nazianzus (330–390, also a Doctor of the Church), said: "When I praise Athanasius, virtue itself is my theme: for I name every virtue as often as I mention him who was possessed of all virtues. He was the true pillar of the Church. His life and conduct were the rule of bishops, and his doctrine the rule of the orthodox faith." Athanasius is remembered in the Church of England with a Lesser Festival on 2 May. Character Historian Cornelius Clifford said in his account: "Athanasius was the greatest champion of Catholic belief on the subject of the Incarnation that the Church has ever known and in his lifetime earned the characteristic title of "Father of Orthodoxy", by which he has been distinguished ever since." St. John Henry Newman described him as a "principal instrument, after the Apostles, by which the sacred truths of Christianity have been conveyed and secured to the world". [Letters..] Historian Cornelius Clifford says: "His career almost personifies a crisis in the history of Christianity; and he may be said rather to have shaped the events in which he took part than to have been shaped by them." The greater majority of Church leaders and the emperors fell into support for Arianism, so much so that Jerome, 340–420, wrote of the period: "The whole world groaned and was amazed to find itself Arian". He, Athanasius, even suffered an unjust excommunication from Pope Liberius (352–366) who was exiled and leant towards compromise, until he was allowed back to the See of Rome. Athanasius stood virtually alone against the world. Historical significance and controversies New Testament canon It was the custom of the bishops of Alexandria to circulate a letter after Epiphany each year confirming the date of Easter, and therefore other moveable feasts. They also took the occasion to discuss other matters. Athanasius wrote forty-five festal letters. Athanasius' 39th Festal Letter, written in 367, is widely regarded as a milestone in the evolution of the canon of New Testament books. Athanasius is the first person to identify the same 27 books of the New Testament that are in use today. Up until then, various similar lists of works to be read in churches were in use. Athanasius compiled the list to resolve questions about such texts as The Epistle of Barnabas. Athanasius includes the Book of Baruch and the Letter of Jeremiah and places the Book of Esther among the "7 books not in the canon but to be read" along with the Wisdom of Solomon, Sirach (Ecclesiasticus), Judith, Tobit, the Didache, and the Shepherd of Hermas. Athanasius' list is similar to the Codex Vaticanus in the Vatican Library, probably written in Rome, in 340 by Alexandrian scribes for Emperor Constans, during the period of Athanasius' seven-year exile in the city. The establishment of the canon was not a unilateral decision by a bishop in Alexandria, but the result of a process of careful investigation and deliberation, as documented in a codex of the Greek Bible and, twenty-seven years later, in his festal letter. Pope Damasus I, the Bishop of Rome in 382, promulgated a list of books which contained a New Testament canon identical to that of Athanasius. A synod in Hippo in 393 repeated Athanasius' and Damasus' New Testament list (without the Epistle to the Hebrews), and the Council of Carthage (397) repeated Athanasius' and Damasus' complete New Testament list. Scholars debate whether Athanasius' list in 367 formed the basis for later lists. Because Athanasius' Canon is the closest canon of any of the Church Fathers to the one used by Protestant churches today, many Protestants point to Athanasius as the Father of the Canon. Episcopal consecration In the light of Francis A. M. Forbes' research and reference to Pope Gregory I's writings, it would appear that Athanasius was constrained to be bishop: She writes that when the Patriarch Alexander was on his death-bed he called Athanasius, who fled, fearing he would be constrained to be made bishop. "When the Bishops of the Church assembled to elect their new Patriarch, the whole Catholic population surrounded the church, holding up their hands to Heaven and crying; "Give us Athanasius!" The Bishops had nothing better. Athanasius was thus elected, as Gregory tells us..." (Pope Gregory I, would have full access to the Vatican Archives). Alban Butler writes on the subject: "Five months after this great Council, Nicae, St Alexander lying on his deathbed, recommended to his clergy and people the choice of Athanasius for his successor, thrice repeating his name. In consequence of his recommendation, the bishops of all Egypt assembled at Alexandria, and finding the people and clergy unanimous in their choice of Athanasius for patriarch, they confirmed the election about the middle of year 326. He seems, then, to have been about thirty years of age." Supporters Christian denominations worldwide revere Athanasius as a saint and teacher. They cite his defence of the Christology described in the first chapter of the Gospel of St. John and his significant theological works (C. S. Lewis calls On the Incarnation of the Word of God a "masterpiece") as evidence of his righteousness. They also emphasize his close relationship with Anthony the Great, the ancient monk who was one of the founders of the Christian monastic movement. The Gospel of St. John and particularly the first chapter demonstrates the Divinity of Jesus. This Gospel in itself is the greatest support of Athanasius' stand. The Gospel of St. John's first chapter began to be said at the end of Mass, we believe as a result of Athanasius, and his life's stand, but quietly, and was later - together with some other originally private devotions - absorbed by the liturgical service proper as so-called Last Gospel. The beginning of John's Gospel was much used as an object of special devotion throughout the Middle Ages; the practice of saying it at the altar grew, and eventually Pius V made this practice universal for the Roman Rite in his edition of the Missal (1570). It became a firm custom with exceptions in using another Gospel in use from 1920. Gregory of Nazianzus (330–390) begins Or. 21 with: "When I praise Athanasius, virtue itself is my theme: for I name every virtue as often as I mention him who was possessed of all virtues. He was the true pillar of the church. His life and conduct were the rule of bishops, and his doctrine the rule of the orthodox faith." Cyril of Alexandria (370–444) in the first letter says: "Athanasius is one who can be trusted: he would not say anything that is not in accord with sacred scripture." (Ep 1). Many modern historians point out that such a hostile attitude towards Athanasius is based on an unfair judgment of historical sources. Pope Pius X said in a letter to philosopher-friend and correspondent in the closing years of his life, (Epist. lxxi, ad Max.): "Let what was confessed by the fathers of Nicaea prevail". Critics Throughout most of his career, Athanasius had many detractors. Classics scholar Timothy Barnes recounts ancient allegations against Athanasius: from defiling an altar, to selling Church grain that had been meant to feed the poor for his own personal gain, and even violence and murder to suppress dissent. Athanasius used "Arian" to describe both followers of Arius, and as a derogatory polemical term for Christians who disagreed with his formulation of the Trinity. Athanasius called many of his opponents "Arian", except for Meletius (Miletus). Scholars now believe that the Arian Party was not monolithic, but held drastically different theological views that spanned the early Christian theological spectrum. They supported the tenets of Origenist thought and subordinationist theology, but had little else in common. Moreover, many labelled "Arian" did not consider themselves followers of Arius. In addition, non-Homoousian bishops disagreed with being labeled as followers of Arius, since Arius was merely a presbyter, while they were fully ordained bishops. The old allegations continue to be made against Athanasius however many centuries later. For example, Richard E. Rubenstein suggests that Athanasius ascended to the rank of bishop in Alexandria under questionable circumstances because some questioned whether he had reached the minimum age of 30 years, and further that Athanasius employed force when it suited his cause or personal interests. Thus, he argues that a small number of bishops who supported Athanasius held a private consecration to make him bishop. Selected works Athanasius.

Azores

The Azores ( , ; ), officially the Autonomous Region of the Azores (), is one of the two autonomous regions of Portugal (along with Madeira). It is an archipelago composed of nine volcanic islands in the Macaronesia region of the North Atlantic Ocean, about west of Lisbon, about northwest of Morocco, and about southeast of Newfoundland, Canada. Its main industries are agriculture, dairy farming, livestock, fishing, and tourism, which is becoming the major service activity in the region. The government of the Azores employs a large percentage of the population directly or indirectly in the service and tertiary sectors. The largest city of the Azores is Ponta Delgada. The culture, dialect, cuisine, and traditions of the Azorean islands vary considerably, because these remote islands were settled sporadically over a span of two centuries. There are nine major Azorean islands and an islet cluster, in three main groups. These are Flores and Corvo, to the west; Graciosa, Terceira, São Jorge, Pico, and Faial in the centre; and São Miguel, Santa Maria, and the Formigas Reef to the east. They extend for more than and lie in a northwest–southeast direction. All of the islands have volcanic origins, although some, such as Santa Maria, have had no recorded activity in the time since the islands were settled several centuries ago. Mount Pico, on the island of Pico, is the highest point in Portugal, at . If measured from their base at the bottom of the ocean to their peaks, which thrust high above the surface of the Atlantic, the Azores are among the tallest mountains on the planet. The climate of the Azores is very mild for such a northerly location, being influenced by its distance from the continents and by the passing Gulf Stream. Because of the marine influence, temperatures remain mild year-round. Daytime temperatures normally fluctuate between depending on season. Temperatures above or below are unknown in the major population centres. It is also generally wet and cloudy. History A small number of alleged hypogea (underground structures carved into rocks) have been identified on the islands of Corvo, Santa Maria, and Terceira by Portuguese archaeologist Nuno Ribeiro, who speculated that they might date back 2,000 years, implying a human presence on the island before the Portuguese. These kinds of structures have been used in the Azores to store grain. Any suggestions by Ribeiro that they might be burial sites are unconfirmed. Detailed examination and dating to authenticate the validity of these speculations is lacking; thus it is unclear whether these structures are natural or human-made and whether they predate the 15th-century Portuguese colonization of the Azores. Discovery and settlement The islands were known to Europeans in the 14th century, and parts of them appear in the Catalan Atlas, created in 1375. Half a century later, in 1427, a captain sailing for Prince Henry the Navigator, possibly Gonçalo Velho, may have rediscovered the Azores, but this is not certain. In Thomas Ashe's 1813 work, A History of the Azores, the author identified a Fleming, Joshua Vander Berg of Bruges, who made landfall in the archipelago during a storm on his way to Lisbon. He stated that the Portuguese explored the area and claimed it for Portugal. Other stories note the discovery of the first islands (São Miguel, Santa Maria and Terceira) by sailors in the service of Henry the Navigator, although there are few documents to support the claims. Although it is commonly said that the archipelago received its name from (goshawk in Portuguese), a common bird at the time of discovery, it is unlikely that the bird nested or hunted on the islands. There were no large animals on Santa Maria, so after its discovery and before settlement began, sheep were let loose on the island to supply future settlers with food. Settlement did not take place right away, however. Gonçalo Velho Cabral gathered resources and settlers for the next three years (1433–1436) and sailed to establish colonies, first on Santa Maria and then on São Miguel. Settlers cleared bush and rocks to plant crops: grain, grapevines, sugar cane, and other plants suitable for local use and of commercial value. They brought domesticated animals, such as chickens, rabbits, cattle, sheep, goats, and pigs, and built houses and established villages. The archipelago was largely settled from mainland Portugal. São Miguel was first settled in 1449, the settlers – mainly from the Estremadura, Alto Alentejo and Algarve areas of mainland Portugal, under the command of Gonçalo Velho Cabral – landed at the site of modern-day Povoação. Many of the early settlers were Portuguese Sephardi Jews who were banished/exiled there by the inquisition on mainland Portugal - many had well known Sephardi surnames such as: Pereira, Oliveira, Cardoso, Pimentel, Pinto, Rodrigues, Mendes, or Nunes. In 1522, Vila Franca do Campo, then the capital of the island, was devastated by an earthquake and landslide that killed about 5,000 people, and the capital was moved to Ponta Delgada. The town of Vila Franca do Campo was rebuilt on the original site and today is a thriving fishing and yachting port. Ponta Delgada received its city status in 1546. From the first settlement, the pioneers applied themselves to agriculture, and by the 15th century Graciosa exported wheat, barley, wine and brandy. The goods were sent to Terceira largely because of the proximity of the island. The first reference to the island of São Jorge was made in 1439, but the actual date of discovery is unknown. In 1443, the island was already inhabited, but active settlement only began with the arrival of the noble Flemish native Willem van der Haegen. Arriving at Topo, where he lived and died, he became known as Guilherme da Silveira to the islanders. João Vaz Corte-Real received the captaincy of the island in 1483. Velas became a town before the end of the 15th century. By 1490, there were 2,000 Flemings living in the islands of Terceira, Pico, Faial, São Jorge and Flores. Because there was such a large Flemish settlement, the Azores became known as the Flemish Islands or the Isles of Flanders. Prince Henry the Navigator was responsible for this settlement. His sister, Isabel, was married to Duke Philip of Burgundy, of which Flanders was a part. There was a revolt against Philip's rule, and disease and hunger became rampant. Isabel appealed to Henry to allow some of the unruly Flemings to settle in the Azores. He granted this and supplied them with the necessary transportation and goods. The settlement of the unoccupied islands started in 1439 with people mainly from the continental provinces of Algarve and Alentejo. In 1583, Philip II of Spain, as king of Portugal, sent his fleet to clear the Azores of a combined multinational force of adventurers, mercenaries, volunteers and soldiers who were attempting to establish the Azores as a staging post for a rival pretender to the Portuguese throne. Following the success of his fleet at the Battle of Ponta Delgada captured enemies were hanged from yardarms, as they were considered pirates by Philip II. Opponents receiving the news variously portrayed Philip II as a despot or "Black Legend"; the sort of insult widely made against contemporary monarchs engaged in aggressive empire building and the European wars of religion. An English raid of the Azores in 1589 successfully plundered some harbouring ships and islands; a repeat eight years later, the Islands Voyage, failed. Spain held the Azores under the "Babylonian captivity" of 1580–1642. In the late 16th century, the Azores and Madeira began to face problems of overpopulation. Spawning from that particular economic problem, some of the people began to emigrate to Brazil. Iberian Union Following the death of Henry, the Cardinal-King of Portugal in 1580, the nation fell into a dynastic crisis with various pretenders to the Crown of Portugal, the most powerful of which was king Phillip II of Spain, who justified his rights to the Portuguese throne by the fact that his mother was a Portuguese royal princess, his maternal grandfather being king Manuel I of Portugal. Following his proclamation in Santarém, António, Prior of Crato was acclaimed in the Azores in 1580 (through his envoy António da Costa) but was expelled from the continent by the Spaniards following the Battle of Alcântara. Yet, through the administration of Cipriano de Figueiredo, governor of Terceira (who continued to govern Terceira in the name of ill-fated, former King Sebastian of Portugal), the Azoreans resisted Spanish attempts to conquer the islands (including specifically at the Battle of Salga). It was Figueiredo and Violante do Canto who helped organize a resistance on Terceira that influenced some of the response of the other islands, even as internal politics and support for Philip's faction increased on the other islands (including specifically on São Miguel, where the Gonçalvez da Câmara family supported the Spanish pretender). The Azores were the last part of the Portuguese Empire to resist Philip's reign over Portugal (Macau resisted any official recognition), until the defeat of forces loyal to the Prior of Crato with the Conquest of the Azores in 1583. Portuguese control resumed with the end of the Iberian Union in 1640, and the beginning of the Portuguese Restoration War, not by the professional military, who were occupied with warfare on the Portuguese mainland, but by local people attacking a fortified Castilian garrison. Liberal Wars The Portuguese Civil War (1828–1834) had strong repercussions in the Azores. In 1829, in Praia da Vitória, the liberals won over the absolutists, making Terceira Island the main headquarters of the new Portuguese regime and also where the Council of Regency () of Maria II of Portugal was established. Beginning in 1868, Portugal issued its stamps overprinted with "" for use in the islands. Between 1892 and 1906, it also issued separate stamps for the three administrative districts of the time. During the 18th and 19th centuries, Graciosa was host to many prominent figures, including Chateaubriand, the French writer who passed through upon his escape to America during the French Revolution; Almeida Garrett, the Portuguese poet who visited an uncle and wrote some poetry while there; and Prince Albert of Monaco, the 19th-century oceanographer who led several expeditions in the waters of the Azores. He arrived on his yacht Hirondelle, and visited the furna da caldeira, the noted hot springs grotto. In 1869, the author Mark Twain published The Innocents Abroad, a travel book, where he described his time in the Azores. From 1836 to 1976, the archipelago was divided into three districts, equivalent (except in area) to those in the Portuguese mainland. The division was arbitrary and did not follow the natural island groups, rather reflecting the location of each district capital on the three main cities (none of which were on the western group). Angra do Heroísmo consisted of Terceira, São Jorge, and Graciosa, with the capital at Angra do Heroísmo on Terceira. Horta consisted of Pico, Faial, Flores, and Corvo, with the capital at Horta on Faial. Ponta Delgada consisted of São Miguel and Santa Maria, with the capital at Ponta Delgada on São Miguel. Modern period In 1931, the Azores (together with Madeira and Portuguese Guinea) revolted against the Ditadura Nacional and were held briefly by military rebels. In 1943, during World War II, the Portuguese ruler António de Oliveira Salazar leased air and naval bases in the Azores to Great Britain. The occupation of these facilities in October 1943 was codenamed Operation Alacrity by the British. This was a key turning point in the Battle of the Atlantic, enabling the Royal Air Force, the U.S. Army Air Forces, and the U.S. Navy to provide aerial coverage in the Mid-Atlantic gap. This helped them to protect convoys and to hunt hostile German U-boats. In 1944, the U.S. constructed a small and short-lived air base on the island of Santa Maria. In 1945, a new base was constructed on the island of Terceira, named Lajes Field. This air base is in an area called Lajes, a broad, flat sea terrace that had been a large farm. Lajes Field is a plateau rising out of the sea on the northeast corner of the island. This air base is a joint American and Portuguese venture. Lajes Field continues to support the American and Portuguese Armed Forces. During the Cold War, U.S. Navy P-3 Orion anti-submarine warfare squadrons patrolled the North Atlantic Ocean for Soviet Navy submarines and surface warships. Since its opening, Lajes Field has been used for refuelling American cargo planes bound for Europe, Africa, and the Middle East. The U.S. Navy keeps a small squadron of its ships at the harbor of Praia da Vitória, southeast of Lajes Field. The airfield also has a small commercial terminal handling scheduled and chartered passenger flights from the other islands in the Azores, Europe, Africa, and North America. Following the Carnation Revolution of 1974, which deposed the Estado Novo dictatorship in Lisbon, Portugal and its territories across the world entered into a period of great political uncertainty. The Azorean Liberation Front attempted to take advantage of this instability immediately after the revolution, hoping to establish an independent Azores, until operations ceased in 1975. In 1976, the Azores became the Autonomous Region of the Azores (), one of the autonomous regions of Portugal, and the subdistricts of the Azores were eliminated. In 2003, the Azores saw international attention when United States President George W. Bush, British Prime Minister Tony Blair, Spanish Prime Minister José María Aznar and Portuguese Prime Minister José Manuel Durão Barroso held a summit there days before the commencement of the Iraq War. Geography Physical geography The archipelago of the Azores is located in the middle of the northern hemisphere of the Atlantic Ocean and extends along a west-northwest to east-southeast orientation (between 36.5°–40° North latitudes and 24.5°–31.5° West longitudes) in an area approximately wide. The islands of the Azores emerged from what is called the Azores Plateau, a 5.8 million km2 region that is morphologically accented by a depth of . The nine islands that compose the archipelago occupy a surface area of , that includes both the main islands and many islets located in their vicinities. They range in surface area from the largest, São Miguel, at to the smallest, Corvo, at approximately . Each of the islands has its own distinct geomorphological characteristics that make them unique: Corvo (the smallest island) is a crater of a major Plinian eruption; Flores (its neighbor on the North American Plate) is a rugged island carved by many valleys and escarpments; Faial is characterized for its shield volcano and caldera (Caldeira Volcano); Pico, is the highest point, at , in the Azores and continental Portugal; Graciosa is known for its active Furnas do Enxofre and mixture of volcanic cones and plains; São Jorge is a long slender island, formed from fissural eruptions over thousands of years; Terceira, almost circular, is the location of one of the largest craters in the region; São Miguel is the largest island and is pitted with many large craters and fields of spatter cones; and Santa Maria, the oldest island, is heavily eroded, being one of the few places to encounter brown sandy beaches in the archipelago. These islands can be divided into three recognizable groups located on the Azores Plateau: The Eastern Group () of São Miguel, Santa Maria and Formigas Islets The Central Group () of Terceira, Graciosa, São Jorge, Pico and Faial The Western Group () of Flores and Corvo. São Jorge, Pico and Faial are also known collectively as Islands of the Triangle (). Several sub-surface reefs (particularly the Dollabarat on the fringe of the Formigas), banks (specifically the Princess Alice Bank and D. João de Castro Bank), as well as many hydrothermal vents and sea-mounts are monitored by the regional authorities, owing to the complex geotectonic and socioeconomic significance within the economic exclusion zone of the archipelago. Geology From a geostructural perspective, the Azores is located above an active triple junction between three of the world's major tectonic plates (the North American Plate, the Eurasian Plate and the African Plate), a condition that has translated into the existence of many faults and fractures in this region of the Atlantic. The westernmost islands of the archipelago (Corvo and Flores) are located on the North American Plate, while the remaining islands are located within the boundary that divides the Eurasian and African plates. The principal tectonic structures that exist in the region of the Azores are the Mid-Atlantic Ridge, the Terceira Rift, the Azores Fracture Zone and the Glória Fault. The Mid-Atlantic Ridge is the main frontier between the North American Plate and the African-Eurasian Plates that crosses the Azores Plateau between the islands of Flores and Faial from north to south then to the southwest; it is an extensive form crossed by many transform faults running perpendicular to its north–south orientation, that is seismically active and susceptible to volcanism. The Terceira Rift is a system of fractures that extends from the Mid-Atlantic Ridge to the Glória Fault that represents the main frontier between the Eurasian and African Plates. It is defined by a line of submarine volcanoes and island mounts that extend northwest to southeast for about , from the area west of Graciosa until the islets of the Formigas, that includes the islands of Graciosa, Terceira and São Miguel. Its northwest limit connects to the Mid-Atlantic Ridge, while the southeast section intersects the Gloria Fault southeast of the island of Santa Maria. The Azores Fracture Zone extends from the Glória Fault and encompasses a relatively inactive area to the south of the islands of the Central and Eastern groups north to the Terceira Rift, along a 45° angle. The Glória Fault, for its part, extends along a linear line from the Azores to the Azores–Gibraltar Transform Fault. The island's volcanism is associated with the rifting along the Azores Triple Junction; the spread of the crust along the existing faults and fractures has produced many of the active volcanic and seismic events, while supported by buoyant upwelling in the deeper mantle, some associate with an Azores hotspot. Most of the volcanic activity has centered, primarily, along the Terceira Rift. From the beginning of the island's settlement, around the 15th century, there have been 28 registered volcanic eruptions (15 terrestrial and 13 submarine). The last significant volcanic eruption, the Capelinhos volcano (), occurred off the coast of the island of Faial in 1957; the most recent volcanic activity occurred in the seamounts and submarine volcanoes off the coast of Serreta and in the Pico-São Jorge Channel. The islands have many examples of volcano-built geomorphology including caves and lava tubes (such as the Gruta das Torres, Algar do Carvão, Gruta do Natal, Gruta das Cinco Ribeiras), the coastal lava fields (like the coast of Feteiras, Faial, the Mistério of Prainha or São João on Pico Island) in addition to the inactive cones in central São Miguel Island, the aforementioned Capelinhos on Faial, the volcanic complexes of Terceira or Plinian caldeira of Corvo Island. The islands of the archipelago were formed through volcanic and seismic activity during the Neogene Period; the first embryonic surfaces started to appear in the waters of Santa Maria during the Miocene epoch (from circa 8 million years ago). The sequence of the island formation has been generally characterized as: Santa Maria (8.12 Ma), São Miguel (4.1 Ma), Terceira (3.52 Ma), Graciosa (2.5 Ma), Flores (2.16 Ma), Faial (0.7 Ma), São Jorge (0.55 Ma), Corvo (0.7 Ma) and the youngest, Pico (0.27 Ma). Although all islands have experienced volcanism during their geological history, within recorded "human settlement" history the islands of Santa Maria, Graciosa, Flores, and Corvo have not experienced any volcanic eruptions; in addition to active fumaroles and hot-springs, the remaining islands have had sporadic eruptions since the 14th century. Apart from the Capelinhos volcano in 1957–58, the last recorded instance of "island formation" occurred off the coast of São Miguel, when the island of Sabrina was briefly formed. Owing to its geodynamic environment, the region has been a center of intense seismic activity, particularly along its tectonic boundaries on the Mid-Atlantic Ridge and Terceira Rift. Seismic events although frequent, are usually tectonic or vulco-tectonic in nature, but in general are of low to medium intensities, occasionally punctuated by events of level 5 or greater on the Richter magnitude scale. The most severe earthquake was registered in 1757, near Calheta on the island of São Jorge, which exceeded 7 on the Richter magnitude scale. In comparison, the 1522 earthquake that was mentioned by historian Gaspar Frutuoso measured 6.8, but its effects were judged to be X (Extreme) on the Mercalli intensity scale, and was responsible for the destruction of Vila Franca do Campo and landslides that may have killed more than 5,000 of the inhabitants. Biome The archipelago lies in the Palearctic realm and has a unique biotic community that includes the Macaronesian subtropical laurissilva, with many endemic species of plants and animals. There are at least 6,112 terrestrial species, of which about 411 are endemic. The majority (75%) of these endemics are animals, mostly arthropods and mollusks. New species are found regularly in the Azores (e.g., 30 different new species of land snails were discovered circa 2013). Even though the Azores look very green and sometimes wild, the vegetation has been extremely altered. A great part of it has been wiped out in the past 600 years for its valuable wood (for tools, buildings, boats, fire wood, and so on) and to clear land for agriculture. As a result, it is estimated that more than half of insects on the Graciosa island have disappeared or will become extinct. Many cultivated places (which are traditionally dedicated to pasture or to growing taro, potatoes, maize and other crops) have now been abandoned, especially as a result of emigration. Consequently, some invasive plants have filled these deserted and disturbed lands. Hydrangeas are another potential pest, but their threat is less serious. Notwithstanding the fact that hydrangeas were introduced from America or Asia, some locals consider them a symbol of the archipelago and propagate them along roadsides. Cryptomeria, the Japanese cedar, is a conifer extensively grown for its timber. The two most common of these alien species are Pittosporum undulatum and Hedychium gardnerianum. Reforestation efforts with native laurissilva vegetation have been accomplished successfully in many parts of the Azores. The Azores has at least two endemic living bird species. The Azores bullfinch, or Priolo, is restricted to remnant laurisilva forest in the mountains at the eastern end of São Miguel and is classified by BirdLife International as endangered. Monteiro's storm petrel, described to science as recently as 2008, is known to breed in just two locations in the islands but may occur more widely. An extinct species of owl, the São Miguel scops owl, has recently been described, which probably became extinct after human settlement because of habitat destruction and the introduction of alien species. Five species of flightless rail (Rallus spp.) once existed on the islands, as did a flightless quail (Coturnix sp.) and another species of bullfinch, the greater Azores bullfinch, but these also went extinct after human colonization. Eleven subspecies of bird are endemic to the islands. The Azores has an endemic bat, the Azores noctule, which has an unusually high frequency of diurnal flight. The islets of the Formigas (the Portuguese word for "ants"), including the area known as the Dollabarat Reef, have a rich environment of maritime species, such as black coral and manta rays, different species of sharks, whales, and sea turtles. Seventeen new marine reserves (with special conservation status) were added to the Azorean Marine Park (which covers around ). On São Miguel there are notable micro-habitats formed by hot springs that host extremophile microorganisms. Climate The archipelago is spread out at roughly the same latitude as the southern half of mainland Portugal, but its location in the mid-Atlantic Ocean gives it a generally tepid, oceanic, mild to warm subtropical climate, with mild annual oscillations. The Azores archipelago is located in a transition and confrontation zone between air masses of tropical origin and masses of cooler air of polar origin. The climate of the archipelago is largely determined by variations in the atmospheric pressure field over the North Atlantic. These variations conditioned by the mass of the American Continent and the Atlantic water mass are overlapped by a semi-permanent subtropical Atlantic anticyclone, commonly known as the Azores High. This anticyclone experiences seasonal variations which can affect the archipelago in many ways. In winter, the Azores anticyclone is positioned further south, and allows for a descent of the Polar front, approaching it to the archipelago. In summer, on the other hand, the anticyclone's movement further north, leads to the departure of the polar front and its associated disturbances towards higher latitudes. Far enough away from the mainland coasts, the continental air masses that reach the archipelago are weakened by the maritime influence. The same can not be said for the higher altitudes (e.g. Mount Pico), where upper air masses of a continental origin and with a more direct pathway can reach the surface and present those areas with drier air and more extreme temperatures. At the same time, this free atmosphere circulating air transports aerosols to the archipelago, namely volcanic ash or fine sands from the Sahara desert, which sporadically affect the radiation and air quality. Daily maximum temperatures at low altitudes usually range between . The average annual rainfall generally increases from east to west, ranging from in Santa Maria to in Flores and reaching values above on the highlands of Pico. Under the Köppen climate classification, the eastern group (São Miguel and Santa Maria) is usually classified as Mediterranean while the central and western group (especially Flores and Corvo) is increasingly more humid subtropical and overall rainier because of the effects of the Gulf Stream. This stream has a large effect over the sea temperature which varies between in February and March, and in August and September, and increases earlier in the western group. Salvador Rivas-Martínez data presents several different bioclimatic zones for the Azores. Seasonal lag is extreme in the low-sun half of the year, with December being milder than April in terms of mean temperatures. During summer the lag is somewhat lower, with August being the warmest month, though September is usually as warm or warmer than July. Although temperatures as warm as have been recorded on Pico, neither Ponta Delgada nor Angra do Heroísmo, the two largest cities, have ever gone above . There has never been a frost, snowfall, freeze or even temperatures below recorded at sea level on any of the islands. The coldest weather in winter usually comes from northwesterly air masses originating from Labrador in Canada. However, since those air masses are warmed up as they pass across the warmer Atlantic Ocean, temperatures by day even then exceed . The average relative humidity can range from 80% at the coast to over 90% above . However, higher elevations above the planetary boundary layer can experience extremely low values close to 10%. Summers are especially humid in August and may increase the perceived temperature by a few degrees. Winters are not only very mild but also very humid and contribute substantially to the annual precipitation. Insolation is relatively low, with 35-40% of the total possible value for sunshine, and higher in topographically lower islands such as Graciosa or Santa Maria, inversely proportional to precipitation. This is directly caused by the orographic lift of humid, air masses and is especially pronounced in islands marked by high orography. Hurricanes With a greater rarity, especially in late summer and autumn, despite the northern position that the archipelago occupies, the Azores can be affected by the passage of tropical cyclones, or tropical storms derived from them, some can result from anomalies of low latitude systems while others result from the return, back to the Atlantic, after a route close to or even over the American continent. Though often small and in the process of dissipation, these cyclones result in many of the worst storms the archipelago is subject to. A total of 14 tropical or subtropical cyclones have affected the region in history. Most of them were either extratropical or tropical storms when they affected the region, although several Category 1 hurricanes have reached the Azores. Two major hurricanes have impacted the islands: Hurricane Ophelia in 2017 (Category 3) and Hurricane Lorenzo in 2019 (Category 2). The following storms have impacted the region while at Category 1 strength: Hurricane Fran in 1973, Hurricane Emmy in 1976, Hurricane Gordon in 2006, Hurricane Gordon in 2012 and Hurricane Alex in 2016. Several tropical storms have hit the region, including Tropical Storm Irma in 1978, Hurricane Bonnie in 1992, Hurricane Charley in 1992, Hurricane Erika in 1997, and Hurricane Gaston in 2016. Storms that were extratropical when they impacted the region include Hurricane Tanya in 1995, Tropical Storm Ana in 2003 and Tropical Storm Grace in 2009. In addition, the 2005 Azores subtropical storm affected the region in October 2005. Economy In order of importance, the main sectors of employment of the Azores are services, agriculture, fishery, industry and tourism. Demographics The Azores are divided into 19 municipalities (); each municipality is further divided into freguesias (civil administrative parishes), of which there is a total of 156 in all of the Azores. There are six cities () in the Azores: Ponta Delgada, Lagoa and Ribeira Grande on the island of São Miguel; Angra do Heroísmo and Praia da Vitória on the island of Terceira, and Horta on Faial. Three of these, Ponta Delgada, Angra and Horta are considered capital/administrative cities to the regional government: homes to the President (Ponta Delgada), the Judiciary (Angra) and the Regional Assembly (Horta). Angra also serves as the ecclesiastical centre of the Roman Catholic Diocese of Angra, the episcopal see of the Azores. Population According to the 2019 Census, population in the Azores was 242,796. The Azores were uninhabited when Portuguese navigators arrived in the early 15th century; settlement began in 1439 with migrants from several regions of mainland Portugal and from Madeira. North African and Sephardic Jews settled on the islands in large numbers. Moorish (Muslim) prisoners and African slaves from Guinea Cape Verde, and São Tomé contributed to the population as well. Thus the Azorean population received a significant contribution from people with geographic backgrounds other than Portuguese. The islands sometimes served as a waypoint for ships carrying African slaves. Moorish and African genetic heritage, likely facilitated by the African slavery, and supported by historical reports, is supported by mtDNA genetic data. Contributions from Sephardic Jews and Northern Europe also are supported by the analysis of genetic data. In addition to Portguese and Africans, Moors, Sephardic Jews, Madeirans, as well as Flemish, French, and Spanish settlers migrated to the Azores. Genetic analysis suggests that the archipelago was populated mainly from Portugal; however, contributions from other lineages are significant. Emigration Since the 17th century, many Azoreans have emigrated, mainly to Brazil, Uruguay, the United States and Canada. Rhode Island and southeastern Massachusetts are the primary destination for Azorean emigrants. From 1921 to 1977, about 250,000 Azoreans immigrated to Rhode Island and Massachusetts. Northern California was the final destination for many of the Massachusetts immigrants who then moved on to the San Joaquin Valley, especially the city of Turlock. In the late 19th century many Azoreans immigrated to the Hawaiian islands. The tuna fishing industry drew a significant number of Azoreans to the Point Loma neighborhood of San Diego. During the Great Recession of the early 21st century, Portugal was in a recession from 2011 until 2013, which resulted in high levels of unemployment across the mainland as well as the Azores. The Great Recession led to an increase of emigration from the Azores. Florianópolis and Porto Alegre in the Southern Region of Brazil were founded by Azoreans, who accounted for over half of Rio Grande do Sul and Santa Catarina's populations in the late 18th century. As late as 1960, mass immigration currents were registered to Brazil, and many were from the Azores. Politics Since 1976, the Azores has been an autonomous region integrated within the framework of the Portuguese Republic. It has its own government and autonomous legislature within its own political-administrative statute and organic law. Its governmental organs include: the legislative assembly, a unicameral parliament composed of 52 elected deputies, elected by universal suffrage for a four-year term; the regional government and presidency, with parliamentary legitimacy, composed of a president, a vice-president and seven regional secretaries responsible for day-to-day operations. It is represented in the Council of Ministers by a representative appointed by the president of the Republic, which was created during the revision of the constitution of 2004 (which, among other things, removed the older Portuguese representative that was appointed by the president of the Republic, beholden to the Council of State and coincident with the president). Since becoming a Portuguese autonomous region, the executive branch of the regional authority has been located in Ponta Delgada, the legislative branch in Horta, and the judicial branch in Angra do Heroísmo. The islands of the archipelago do not have independent status in law, except in electoral law and are governed by 19 municipalities that subdivide the islands. In addition, until the administrative reform of the 19th century, the following civil parishes had municipal standing: Topo (today integrated into the municipality of Calheta, São Jorge); Praia (today integrated into municipality of Santa Cruz da Graciosa); São Sebastião (today an integral part of the municipality of Angra do Heroísmo); Capelas (now part of the municipality of Ponta Delgada); and Água de Pau (now a civil parish in the municipality of Lagoa). These civil parishes still retain their titles of "vila" in name only; the populations of Capelas and neighbouring parish still protest the change and promote the restoration of their status. The municipalities are further subdivided into several civil parishes, with the exception of Corvo (the only municipality by law without a civil parish, owing to its size). Azorean politics is dominated by the two largest Portuguese political parties, the Socialist Party and Social Democratic Party, the former holding a majority in the Legislative Assembly. The Democratic and Social Center / People's Party, the Left Bloc, the Unitary Democratic Coalition and the People's Monarchist Party are also represented. , the President of the Azores is Social Democratic Party leader José Manuel Bolieiro. Although the Socialist Party dominates the regional politics, the Social Democratic Party is traditionally popular in city and town council elections. As part of Portugal, the Azores are in the European Union and Schengen Area. They are also in the European Union Customs Union and VAT area but levy a lower rate of VAT than applies on the mainland. The Azores, like Madeira and the Canary Islands, are among member state territories with special status, as one of the designated "Outermost Regions". Transport Aviation Each of the nine islands has an airport, although the majority are airfields rather than airports. The primary (and busiest) airport of the island group is João Paulo II Airport. The commercial terminals in Ponta Delgada, Horta, Vila do Porto and Santa Cruz das Flores are operated by ANA – Aeroportos de Portugal, a public entity that oversees the operations of airports across Portugal. The remaining, except for Lajes Field, are operated by the Regional Government. Lajes is a military airbase, as well as a commercial airport, and is operated by the Portuguese Armed Forces in conjunction with the United States. The airports are: Santa Maria: Santa Maria Airport (LPAZ) São Miguel: João Paulo II Airport (LPPD) Terceira: Lajes Airport (LPLA) São Jorge: São Jorge Airport (LPSJ) Pico: Pico Airport (LPPI) Faial: Horta Airport (LPHR) Graciosa: Graciosa Airport (LPGR) Flores: Flores Airport (LPFL) Corvo: Corvo Airport (LPCR) Marine transportation The Azores has had a long history of marine transport to overcome distances and establish inter-community contacts and trade. Consequently, the shipbuilding industry developed in many islands, from small fishing boats to whaling sloops and larger passenger services. Passenger traffic to the main islands (São Miguel, Santa Maria, Terceira and Faial) began in the 17th century, and between the 18th–19th century, the Pico Yacht controlled the lucrative summer traffic season. After 1871, the Insulana Shipping Company was the only entity responsible for regular traffic between the islands (except Corvo), Madeira and the United States. Finally, cargo and passenger transportation ceased in the 1970s, and the ships were sold or converted into tuna fishing boats. For the next 20 years, commercial maritime service between the islands ceased (except between Faial-Pico and Lajes das Flores-Vila do Corvo). Transmaçor (Transportes Marítimos Açorianos, Lda.) was founded in 1987. The shipping company operates four to six daily connections between Horta and Madalena throughout the year, using its small fleet of ships, in addition to inter-island connections between Faial, Pico, São Jorge and Terceira during the summer months. New initiatives began in the late 1990s: the catamaran Iapetos began services, followed by Lady of Mann and Golfinho Azul (chartered by Açorline). In 2005, Atlânticoline was established, providing transport services. In 2009, Atlanticoline was involved in a controversial rejection of a 750-passenger, 150-vehicle ship ordered from the Estaleiros de Viana do Castelo (ENVC). The Atlantida, a 50 million Euro cruiser (as part of a two-ship deal with the other named Anticiclone) was rejected in 2009 by Atlanticoline for the under-performance of the power-plant. Although it would only result in a five-minute delay between islands, the public company rejected the ship, and the contract was broken over the builder's inability to deliver the required ship on time. While the ship was being shopped to other interested parties (Hugo Chávez once considered purchasing the ferryboat in 2010), no interested buyers appeared, and ENVC decided to cede the Atlantida to Atlânticoline as part of the latter's open international competition to charter two ships in 2012. In June 2011, the Regional Government announced that it would purchase 60% of Transmaçor, equivalent to 500,000 Euro of the company's capital. With this transaction the autonomous government of the Azores ceded control, of which it once had 88% of the capital. The signed memorandum of understanding concluded negotiations between the various parties involved, under which the liability of Transmaçor (worth a total of 8 million Euro) was divided equally between the government and businessman José E. Almeida, who is now the holder of a majority stake in the company. Similarly, the Regional Government approved the consolidation of the three individual port authorities (Administração dos Portos do Triângulo e Grupo Ocidental, Administração dos Portos da Terceira e Graciosa and the Administração dos Portos das Ilhas de São Miguel e Santa Maria) and regional Portos dos Açores into one entity that resulted in a 2.2 million Euro cost savings, in addition to a reduction from 11 to three administrators. Culture Religious festivals, patron saints and traditional holidays mark the Azorean calendar. The most important religious events are tied with the festivals associated with the cult of the Holy Spirit, commonly referred to as the festivals of the Holy Spirit (or ), rooted in millenarian dogma and held on all islands from May to September. These festivals are very important to the Azorean people, who are primarily Roman Catholic, and combine religious rituals with processions celebrating the benevolence and egalitarianism of neighbours. These events are centred around or , small buildings that host the meals, adoration and charity of the participants, and used to store the artefacts associated with the events. On Terceira, for example, these impérios have grown into ornate buildings painted and cared for by the local brotherhoods in their respective parishes. The events focus on the members of local parishes, not tourists, but all are welcome, as sharing is one of the main principles of the festivals. Some limited events focus on tourists, including a public event that the city government of Ponta Delgada on the island of São Miguel holds, which attracts visitors and locals. The Festival of the Lord Holy Christ of the Miracles () in Ponta Delgada is the largest individual religious event in the Azores and takes place on Rogation Sunday. Pilgrims from within the Portuguese diaspora normally travel to Ponta Delgada to participate in an afternoon procession behind the image of Christ along the flower-decorated streets of the city. Although the solemn procession is only held on one day, the events of the Festival of Senhor Santo Cristo occur over a period of a week and involve a ritual of moving the image between the main church and convent nightly, ultimately culminating in the procession, which is televised within the Azores and to the Portuguese diaspora. The Sanjoaninas Festivities in Angra do Heroísmo on Terceira are held in June honoring Saint Anthony, Saint Peter and Saint John the Baptist, in a large religious celebration. The festival of Our Lady of Lourdes (), patron saint of whalers, begins in Lajes on Pico Island on the last Sunday of August and runs through the week—Whalers Week. It is marked by social and cultural events connected to the tradition of whale hunting. The Wine Harvest Festival (), takes place during the first week of September and is a century-old custom of the people of Pico. On Corvo, the people celebrate their patron saint (Our Lady of Miracles) on 15 August every year in addition to the festivals of the Divine Holy Spirit. The (August Sea Festival), takes place every year beginning on 15 August in Praia Formosa on Santa Maria. Also, the (Sea Week), dedicated almost exclusively to water sports, takes place in August in the city of Horta, on Faial. is celebrated in the Azores. Parades and pageants are the heart of the Carnaval festivities. There is lively music, colorful costumes, hand-made masks, and floats. The traditional bullfights in the bullring are ongoing as is the running of bulls in the streets.

Outback

The Outback is a remote, vast, sparsely populated area of Australia. The Outback is more remote than the bush, which includes any location outside the main urban areas. While often envisaged as being arid, the Outback regions extend from the northern to southern Australian coastlines and encompass a number of climatic zones, including tropical and monsoonal climates in northern areas, arid areas in the "red centre" and semi-arid and temperate climates in southerly regions. Geographically, the Outback is unified by a combination of factors, most notably a low human population density, a largely intact natural environment and, in many places, low-intensity land uses, such as pastoralism (livestock grazing) in which production is reliant on the natural environment. The Outback is deeply ingrained in Australian heritage, history and folklore. In Australian art the subject of the Outback has been vogue, particularly in the 1940s. In 2009, as part of the Q150 celebrations, the Queensland Outback was announced as one of the Q150 Icons of Queensland for its role as a "natural attraction". History Indigenous Australians have lived in the Outback for at least 50,000 years and occupied all Outback regions, including the driest deserts, when Europeans first entered central Australia in the 1800s. Many Indigenous Australians retain strong physical and cultural links to their traditional country and are legally recognised as the Traditional Owners of large parts of the Outback under Commonwealth Native Title legislation. Early European exploration of inland Australia was sporadic. More focus was on the more accessible and fertile coastal areas. The first party to successfully cross the Blue Mountains just outside Sydney was led by Gregory Blaxland in 1813, 25 years after the colony was established. People, starting with John Oxley in 1817, 1818 and 1821, followed by Charles Sturt in 1829–1830, attempted to follow the westward-flowing rivers to find an "inland sea", but these were found to all flow into the Murray River and Darling River, which turn south. From 1858 onwards, the so-called "Afghan" cameleers and their beasts played an instrumental role in opening up the Outback and helping to build infrastructure. Over the period 1858 to 1861, John McDouall Stuart led six expeditions north from Adelaide, South Australia into the Outback, culminating in successfully reaching the north coast of Australia and returning without the loss of any of the party's members' lives. This contrasts with the ill-fated Burke and Wills expedition in 1860–61 which was much better funded, but resulted in the deaths of three of the members of the transcontinental party. The Overland Telegraph line was constructed in the 1870s along the route identified by Stuart. In 1865 the surveyor George Goyder, using changes in vegetation patterns, mapped a line in South Australia, north of which he considered rainfall to be too unreliable to support agriculture. Exploration of the Outback continued in the 1950s when Len Beadell explored, surveyed and built many roads in support of the nuclear weapons tests at Emu Field and Maralinga and rocket testing on the Woomera Prohibited Area. Mineral exploration continues as new mineral deposits are identified and developed. While the early explorers used horses to cross the Outback, the first woman to make the journey riding a horse was Anna Hingley, who rode from Broome to Cairns in 2006. Environment Global significance The paucity of industrial land use has led to the Outback being recognised globally as one of the largest remaining intact natural areas on Earth. Global "Human Footprint" and wilderness reviews highlight the importance of Outback Australia as one of the world's large natural areas, along with the Boreal forests and Tundra regions in North America, the Sahara and Gobi deserts and the tropical forests of the Amazon and Congo Basins. The savanna (or grassy woodlands) of northern Australia are the largest, intact savanna regions in the world. In the south, the Great Western Woodlands, which occupy , an area larger than all of England and Wales, are the largest remaining temperate woodland left on Earth. Major ecosystems Reflecting the wide climatic and geological variation, the Outback contains a wealth of distinctive and ecologically-rich ecosystems. Major land types include: the Kimberley and Pilbara regions in northern Western Australia, sub-tropical savanna landscape of the Top End, ephemeral water courses of the Channel Country in western Queensland, the ten deserts in central and western Australia, the Inland Ranges, such as the MacDonnell Ranges, which provide topographic variation across the flat plains, the flat Nullarbor Plain north of the Great Australian Bight, and the Great Western Woodlands in southern Western Australia. Wildlife The Outback is full of very important well-adapted wildlife, although much of it may not be immediately visible to the casual observer. Many animals, such as red kangaroos and dingoes, hide in bushes to rest and keep cool during the heat of the day. Birdlife is prolific, most often seen at waterholes at dawn and dusk. Huge flocks of budgerigars, cockatoos, corellas and galahs are often sighted. On bare ground or roads during the winter, various species of snakes and lizards bask in the sun, but they are rarely seen during the summer months. Feral animals such as camels thrive in central Australia, brought to Australia by pastoralists and explorers, along with the early Afghan drivers. Feral horses known as 'brumbies' are station horses that have run wild. Feral pigs, foxes, cats, goats and rabbits and other imported animals are also degrading the environment, so time and money is spent eradicating them in an attempt to help protect fragile rangelands. The Outback is home to a diverse set of animal species, such as the kangaroo, emu and dingo. The Dingo Fence was built to restrict movements of dingoes and wild dogs into agricultural areas towards the south east of the continent. The marginally fertile parts are primarily utilised as rangelands and have been traditionally used for sheep or cattle grazing, on cattle stations which are leased from the Federal Government. While small areas of the outback consist of clay soils the majority has exceedingly infertile palaeosols. Riversleigh, in Queensland, is one of Australia's most renowned fossil sites and was recorded as a World Heritage site in 1994. The 100 km2 (39 sq mi) area contains fossil remains of ancient mammals, birds and reptiles of Oligocene and Miocene age. Industry Pastoralism The largest industry across the Outback, in terms of the area occupied, is pastoralism, in which cattle, sheep, and sometimes goats are grazed in mostly intact, natural ecosystems. Widespread use of bore water, obtained from underground aquifers, including the Great Artesian Basin, has enabled livestock to be grazed across vast areas in which no permanent surface water exists naturally. Capitalising on the lack of pasture improvement and absence of fertiliser and pesticide use, many Outback pastoral properties are certified as organic livestock producers. In 2014, , most of which is in Outback Australia, was fully certified as organic farm production, making Australia the largest certified organic production area in the world. Tourism Tourism is a major industry across the Outback, and commonwealth and state tourism agencies explicitly target Outback Australia as a desirable destination for domestic and international travellers. There is no breakdown of tourism revenues for the "Outback" per se. However, regional tourism is a major component of national tourism incomes. Tourism Australia explicitly markets nature-based and Indigenous-led experiences to tourists. In the 2015–2016 financial year, 815,000 visitors spent $988 million while on holidays in the Northern Territory alone. There are many popular tourist attractions in the Outback. Some of the well known destinations include: Alice Springs, Northern Territory Arkaroola and Wilpena Pound in the Flinders Ranges of South Australia Australian Stockman's Hall of Fame Birdsville, Queensland Broken Hill, New South Wales Broome Coober Pedy, South Australia Devils Marbles Kakadu National Park Kalgoorlie-Boulder, Western Australia Kata Tjuta (The Olgas) Katherine Gorge Kings Canyon (Watarrka) MacDonnell Ranges Monkey Mia Mount Isa Mount Augustus National Park Tennant Creek, Northern Territory Uluru (Ayers Rock) Willandra Lakes Region Mining Other than agriculture and tourism, the main economic activity in this vast and sparsely settled area is mining. Owing to the almost complete absence of mountain building and glaciation since the Permian (in many areas since the Cambrian) ages, the outback is extremely rich in iron, aluminium, manganese and uranium ores, and also contains major deposits of gold, nickel, copper, lead and zinc ores. Because of its size, the value of grazing and mining is considerable. Major mines and mining areas in the Outback include opals at Coober Pedy, Lightning Ridge and White Cliffs, metals at Broken Hill, Tennant Creek, Olympic Dam and the remote Challenger Mine. Oil and gas are extracted in the Cooper Basin around Moomba. In Western Australia the Argyle diamond mine in the Kimberley is the world's biggest producer of natural diamonds and contributes approximately one-third of the world's natural supply. The Pilbara region's economy is dominated by mining and petroleum industries. Most of Australia's iron ore is also mined in the Pilbara and it also has one of the world's major manganese mines. Population Aboriginal communities in outback regions, such as the Anangu Pitjantjatjara Yankunytjatjara lands in northern South Australia, have not been displaced as they have been in areas of intensive agriculture and large cities, in coastal areas. The total population of the Outback in Australia declined from 700,000 in 1996 to 690,000 in 2006. The largest decline was in the Outback Northern Territory, while the Kimberley and Pilbara showed population increases during the same period. The sex ratio is 1040 males for 1000 females and 17% of the total population is indigenous. Medicine The Royal Flying Doctor Service (RFDS) started service in 1928 and helps people who live in the outback of Australia. In former times, serious injuries or illnesses often meant death due to the lack of proper medical facilities and trained personnel. Education In many outback communities, the number of children is too small for a conventional school to operate. Children are educated at home by the School of the Air. Originally the teachers communicated with the children via radio, but now satellite telecommunication is used instead. Some children attend boarding school, mostly only those in secondary school. Terminology The term "outback" derives from the adverbial phrase referring to the back yard of a house, and came to be used meiotically in the late 1800s to describe the vast sparsely settled regions of Australia behind the cities and towns. The earliest known use of the term in this context in print was in 1869, when the writer clearly meant the area west of Wagga Wagga, New South Wales. Over time, the adverbial use of the phrase was replaced with the present day noun form. It is colloquially said that "the outback" is located "beyond the Black Stump". The location of the black stump may be some hypothetical location or may vary depending on local custom and folklore. It has been suggested that the term comes from the Black Stump Wine Saloon that once stood about out of Coolah, New South Wales on the Gunnedah Road. It is claimed that the saloon, named after the nearby Black Stump Run and Black Stump Creek, was an important staging post for traffic to north-west New South Wales and it became a marker by which people gauged their journeys. "The Never-Never" is a term referring to remoter parts of the Outback. The Outback can also be referred to as "back of beyond" or "back o' Bourke", although these terms are more frequently used when referring to something a long way from anywhere, or a long way away. The well-watered north of the continent is often called the "Top End" and the arid interior "The Red Centre", owing to its vast amounts of red soil and sparse greenery amongst its landscape. Transport The outback is criss-crossed by historic tracks. Most of the major highways have an excellent bitumen surface and other major roads are usually well-maintained dirt roads. The Stuart Highway runs from north to south through the centre of the continent, roughly paralleled by the Adelaide–Darwin railway. There is a proposal to develop some of the roads running from the south-west to the north-east to create an all-weather road named the Outback Highway, crossing the continent diagonally from Laverton, Western Australia (north of Kalgoorlie, through the Northern Territory to Winton, in Queensland. Air transport is relied on for mail delivery in some areas, owing to sparse settlement and wet-season road closures. Most outback mines have an airstrip and many have a fly-in fly-out workforce. Most outback sheep stations and cattle stations have an airstrip and quite a few have their own light plane. Medical and ambulance services are provided by the Royal Flying Doctor Service.

https://en.wikipedia.org/wiki/Absolute%20Infinite

Absolute Infinite

The Absolute Infinite (symbol: Ω) is an extension of the idea of infinity proposed by mathematician Georg Cantor. It can be thought of as a number that is bigger than conceivable or inconceivable quantity, either finite or transfinite. Cantor linked the Absolute Infinite with God, and believed that it had various mathematical properties, including the reflection principle: every property of the Absolute Infinite is also held by some smaller object. Cantor's view Cantor said: Cantor also mentioned the idea in his letters to Richard Dedekind (text in square brackets not present in original): The Burali-Forti paradox The idea that the collection of all ordinal numbers cannot logically exist seems paradoxical to many. This is related to Cesare Burali-Forti's "paradox" which states that there can be no greatest ordinal number. All of these problems can be traced back to the idea that, for every property that can be logically defined, there exists a set of all objects that have that property. However, as in Cantor's argument (above), this idea leads to difficulties. More generally, as noted by A. W. Moore, there can be no end to the process of set formation, and thus no such thing as the totality of all sets, or the set hierarchy. Any such totality would itself have to be a set, thus lying somewhere within the hierarchy and thus failing to contain every set. A standard solution to this problem is found in Zermelo's set theory, which does not allow the unrestricted formation of sets from arbitrary properties. Rather, we may form the set of all objects that have a given property and lie in some given set (Zermelo's Axiom of Separation). This allows for the formation of sets based on properties, in a limited sense, while (hopefully) preserving the consistency of the theory. While this solves the logical problem, one could argue that the philosophical problem remains. It seems natural that a set of individuals ought to exist, so long as the individuals exist. Indeed, naive set theory might be said to be based on this notion. Although Zermelo's fix allows a class to describe arbitrary (possibly "large") entities, these predicates of the meta-language may have no formal existence (i.e., as a set) within the theory. For example, the class of all sets would be a proper class. This is philosophically unsatisfying to some and has motivated additional work in set theory and other methods of formalizing the foundations of mathematics such as New Foundations by Willard Van Orman Quine.

https://en.wikipedia.org/wiki/Acceptance%20testing

Acceptance testing

In engineering and its various subdisciplines, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. It may involve chemical tests, physical tests, or performance tests. In systems engineering, it may involve black-box testing performed on a system (for example: a piece of software, lots of manufactured mechanical parts, or batches of chemical products) prior to its delivery. In software testing, the ISTQB defines acceptance testing as: Acceptance testing is also known as user acceptance testing (UAT), end-user testing, operational acceptance testing (OAT), acceptance test-driven development (ATDD) or field (acceptance) testing. Acceptance criteria are the criteria that a system or component must satisfy in order to be accepted by a user, customer, or other authorized entity. A smoke test may be used as an acceptance test prior to introducing a build of software to the main testing process. Overview Testing is a set of activities conducted to facilitate discovery and/or evaluation of properties of one or more items under test. Each individual test, known as a test case, exercises a set of predefined test activities, developed to drive the execution of the test item to meet test objectives; including correct implementation, error identification, quality verification and other valued detail. The test environment is usually designed to be identical, or as close as possible, to the anticipated production environment. It includes all facilities, hardware, software, firmware, procedures and/or documentation intended for or used to perform the testing of software. UAT and OAT test cases are ideally derived in collaboration with business customers, business analysts, testers, and developers. It's essential that these tests include both business logic tests as well as operational environment conditions. The business customers (product owners) are the primary stakeholders of these tests. As the test conditions successfully achieve their acceptance criteria, the stakeholders are reassured the development is progressing in the right direction. User acceptance test (UAT) criteria (in agile software development) are usually created by business customers and expressed in a business domain language. These are high-level tests to verify the completeness of a user story or stories 'played' during any sprint/iteration. Operational acceptance test (OAT) criteria (regardless if using agile, iterative or sequential development) are defined in terms of functional and non-functional requirements; covering key quality attributes of functional stability, portability and reliability. Process The acceptance test suite may need to be performed multiple times, as all of the test cases may not be executed within a single test iteration. The acceptance test suite is run using predefined acceptance test procedures to direct the testers which data to use, the step-by-step processes to follow and the expected result following execution. The actual results are retained for comparison with the expected results. If the actual results match the expected results for each test case, the test case is said to pass. If the quantity of non-passing test cases does not breach the project's predetermined threshold, the test suite is said to pass. If it does, the system may either be rejected or accepted on conditions previously agreed between the sponsor and the manufacturer. The anticipated result of a successful test execution: test cases are executed, using predetermined data actual results are recorded actual and expected results are compared, and test results are determined. The objective is to provide confidence that the developed product meets both the functional and non-functional requirements. The purpose of conducting acceptance testing is that once completed, and provided the acceptance criteria are met, it is expected the sponsors will sign-off on the product development/enhancement as satisfying the defined requirements (previously agreed between business and product provider/developer). User acceptance testing User acceptance testing (UAT) consists of a process of verifying that a solution works for the user. It is not system testing (ensuring software does not crash and meets documented requirements) but rather ensures that the solution will work for the user (i.e. tests that the user accepts the solution); software vendors often refer to this as "Beta testing". This testing should be undertaken by a subject-matter expert (SME), preferably the owner or client of the solution under test, and provide a summary of the findings for confirmation to proceed after trial or review. In software development, UAT as one of the final stages of a project often occurs before a client or customer accepts the new system. Users of the system perform tests in line with what would occur in real-life scenarios. It is important that the materials given to the tester be similar to the materials that the end user will have. Testers should be given real-life scenarios such as the three most common or difficult tasks that the users they represent will undertake. The UAT acts as a final verification of the required business functionality and proper functioning of the system, emulating real-world conditions on behalf of the paying client or a specific large customer. If the software works as required and without issues during normal use, one can reasonably extrapolate the same level of stability in production. User tests, usually performed by clients or by end-users, do not normally focus on identifying simple cosmetic problems such as spelling errors, nor on showstopper defects, such as software crashes; testers and developers identify and fix these issues during earlier unit testing, integration testing, and system testing phases. UAT should be executed against test scenarios. Test scenarios usually differ from System or Functional test cases in that they represent a "player" or "user" journey. The broad nature of the test scenario ensures that the focus is on the journey and not on technical or system-specific details, staying away from "click-by-click" test steps to allow for a variance in users' behaviour. Test scenarios can be broken down into logical "days", which are usually where the actor (player/customer/operator) or system (backoffice, front end) changes. In industry, a common UAT is a factory acceptance test (FAT). This test takes place before installation of the equipment. Most of the time testers not only check that the equipment meets the specification, but also that it is fully functional. A FAT usually includes a check of completeness, a verification against contractual requirements, a proof of functionality (either by simulation or a conventional function test) and a final inspection. The results of these tests give clients confidence in how the system will perform in production. There may also be legal or contractual requirements for acceptance of the system. Operational acceptance testing Operational acceptance testing (OAT) is used to conduct operational readiness (pre-release) of a product, service or system as part of a quality management system. OAT is a common type of non-functional software testing, used mainly in software development and software maintenance projects. This type of testing focuses on the operational readiness of the system to be supported, and/or to become part of the production environment. Acceptance testing in extreme programming Acceptance testing is a term used in agile software development methodologies, particularly extreme programming, referring to the functional testing of a user story by the software development team during the implementation phase. The customer specifies scenarios to test when a user story has been correctly implemented. A story can have one or many acceptance tests, whatever it takes to ensure the functionality works. Acceptance tests are black-box system tests. Each acceptance test represents some expected result from the system. Customers are responsible for verifying the correctness of the acceptance tests and reviewing test scores to decide which failed tests are of highest priority. Acceptance tests are also used as regression tests prior to a production release. A user story is not considered complete until it has passed its acceptance tests. This means that new acceptance tests must be created for each iteration or the development team will report zero progress. Types of acceptance testing Typical types of acceptance testing include the following User acceptance testing This may include factory acceptance testing (FAT), i.e. the testing done by a vendor before the product or system is moved to its destination site, after which site acceptance testing (SAT) may be performed by the users at the site. Operational acceptance testingAlso known as operational readiness testing, this refers to the checking done to a system to ensure that processes and procedures are in place to allow the system to be used and maintained. This may include checks done to back-up facilities, procedures for disaster recovery, training for end users, maintenance procedures, and security procedures. Contract and regulation acceptance testing In contract acceptance testing, a system is tested against acceptance criteria as documented in a contract, before the system is accepted. In regulation acceptance testing, a system is tested to ensure it meets governmental, legal and safety standards. Factory acceptance testing Acceptance testing conducted at the site at which the product is developed and performed by employees of the supplier organization, to determine whether a component or system satisfies the requirements, normally including hardware as well as software. Alpha and beta testing Alpha testing takes place at developers' sites, and involves testing of the operational system by internal staff, before it is released to external customers. Beta testing takes place at customers' sites, and involves testing by a group of customers who use the system at their own locations and provide feedback, before the system is released to other customers. The latter is often called "field testing".

Archbishopric of Riga

The Archbishopric of Riga (, ) was an archbishopric in Medieval Livonia, a subject to the Holy See. It was established in 1186 as the bishopric of Livonia at Ikšķile, then after moving to Riga it became the bishopric of Riga in 1202 and was elevated to an archbishopric in 1255. Archbishops of Riga The archbishops of Riga were also the secular rulers of Riga until 1561 when during the reformation the territory converted from Catholicism to Lutheranism and all church territories were secularized. The see was restored as a diocese of the Catholic Church in 1918 and raised into an archdiocese in 1923. Bishops and Archbishops of Riga A new Bishopric of Livonia was established in Latgalia in 1621 during the Inflanty Voivodeship of the Polish–Lithuanian Commonwealth. Coinage The Archbishops of Riga were innovators in the field of minting currency, reviving techniques abandoned since the collapse of Rome. The names of individual archbishops after 1418, as well as the years of their respective reigns, are stamped on Livonian pennies excavated at archaeological sites. In many cases, this is the only biographical data available. No Livonian pennies before 1418 have been found.

Albert Frederick, Duke of Prussia

Albert Frederick (; ; 7 May 1553 – 27 August 1618) was the Duke of Prussia, from 1568 until his death. He was a son of Albert of Prussia and Anna Marie of Brunswick-Lüneburg. He was the second and last Prussian duke of the Ansbach branch of the Hohenzollern family. Duke of Prussia Albert became Duke of Prussia after paying feudal homage to his cousin, the King of Poland, Zygmunt August, on 19 July 1569 in Lublin. The homage was described by the Polish chronicler Jan Kochanowski in his work Proporzec ("Standard"). During the 1573 Polish election, Albert Frederick attempted to gain acceptance to the Polish senate but was opposed by the powerful Jan Zamoyski (later Grand Hetman of the Crown of the Kingdom of Poland) who feared the influence of Protestants in the Polish legislative body. Albert Frederick initially refused to recognize the election of Stefan Bathory and supported the candidacy of Maximilian of Habsburg. However, at the Toruń sejm of October 1576 he gave his support to the new monarch. As the great grandson of the Polish king Casimir IV Jagiellon, and as a Duke in Prussia who was fluent in Polish, Albert Frederick was seriously considered for a time as a possible candidate for the Polish throne. He particularly enjoyed the support of Polish Lutherans. In 1572 he began to exhibit signs of mental disorder. In early 1578, the regency was taken over by his cousin, George Frederick of Brandenburg-Kulmbach (1539–1603). After George Frederick's death in 1603, the Polish king Sigismund III Vasa appointed Joachim Frederick as regent in 1605, and permitted his son, John Sigismund, to succeed him in 1611. The latter became Duke of Prussia after Albert Frederick's death in 1618. Marriage Albert Frederick was married in 1573 to Marie Eleonore of Cleves, a daughter of Wilhelm, Duke of Jülich-Cleves-Berg and Archduchess Maria of Austria (1531–1581). Maria was a daughter of Ferdinand I, Holy Roman Emperor and Anna of Bohemia and Hungary. Issue Albert Frederick and Marie were parents to seven children: Anna of Prussia (3 July 1576 – 30 August 1625). Married John Sigismund, Elector of Brandenburg. Marie of Prussia (23 January 1579 – 21 February 1649). Married Christian, Margrave of Brandenburg-Bayreuth. Albert Frederick of Prussia (1 June 1580 – 8 October 1580). Sophie of Prussia (31 March 1582 – 4 December 1610). Married Wilhelm Kettler of Courland. Eleanor of Prussia (21 August 1583 – 9 April 1607). Married Joachim Frederick, Elector of Brandenburg. Wilhelm Frederick of Prussia (23 June 1585 – 18 January 1586). Magdalene Sibylle of Prussia (31 December 1586 – 22 February 1659). Married John George I, Elector of Saxony. At his death, the duchy passed to his son-in-law John Sigismund, Margrave of Brandenburg, combining the two territories under a single dynasty and forming Brandenburg-Prussia.

https://en.wikipedia.org/wiki/Ansbach

Ansbach

Ansbach (; ) is a city in the German state of Bavaria. It is the capital of the administrative region of Middle Franconia. Ansbach is southwest of Nuremberg and north of Munich, on the river Fränkische Rezat, a tributary of the river Main. In 2020, its population was 41,681. Developed in the 8th century as a Benedictine monastery, it became the seat of the Hohenzollern family in 1331. In 1460, the Margraves of Brandenburg-Ansbach lived here. The city has a castle known as Margrafen–Schloss, built between 1704 and 1738. It was not badly damaged during the World Wars and hence retains its original historical baroque sheen. Ansbach is now home to a US military base and to the Ansbach University of Applied Sciences. The city has connections via autobahn A6 and highways B13 and B14. Ansbach station is on the Nürnberg–Crailsheim and Treuchtlingen–Würzburg railways and is the terminus of line S4 of the Nuremberg S-Bahn. Name origin Ansbach was originally called Onoltesbach (about 790 AD), a term composed of three parts. The individual word elements are "Onold" (the city founder's name), the Suffix "-es" (a possessive ending, like "-'s" in English) and the Old High German expression "pah" or "bach" (for brook). The name of the city has slightly changed throughout the centuries into Onoltespah (837 AD), Onoldesbach (1141 AD), Onoldsbach (1230 AD), Onelspach (1338 AD), Onsbach (1508 AD) and finally Ansbach (1732 AD). It was also formerly known as Anspach. History According to folklore, towards the end of the 7th century a group of Franconian peasants and their families went up into the wilderness to found a new settlement. Their leader Onold led them to an area called the "Rezattal" (Rezat valley). This is where they founded the "Urhöfe" (meaning the first farms: Knollenhof, Voggenhof and Rabenhof). Gradually more settlers, such as the "Winden-Tribe" came, and the farms grew into a small village. Many villages around Ansbach were founded by the "Winden" during that period (even today, their settlements can easily identified by their names, like "Meinhardszwinden", "Dautenwinden" or "Brodswinden"). A Benedictine monastery was established there around 748 by the Frankish noble St Gumbertus. The adjoining village of Onoltesbach was first noticed as a proper town in 1221. The counts of Öttingen ruled over Ansbach until the Hohenzollern burgrave of Nürnberg took over in 1331. The Hohenzollerns made Ansbach the seat of their dynasty until their acquisition of the Margraviate of Brandenburg in 1415. After the 1440 death of Frederick I, a cadet branch of the family established itself as the margraves of Ansbach. George the Pious introduced the Protestant Reformation to Ansbach in 1528, leading to Gumbertus Abbey's secularization in 1563. The Markgrafenschloß was built between 1704 and 1738. Its gardens continued to be a notable attraction into the 1800s. In 1791, the last margrave sold his realm to the Kingdom of Prussia. In 1796, the Duke of Zweibrücken, Maximilian Joseph — the future Bavarian king— was exiled to Ansbach the French took Zweibrücken. In Ansbach, Maximilian von Montgelas wrote an elaborate concept for the future political organization of Bavaria, which is known as the Ansbacher Mémoire. Napoleon forced Prussia to cede Ansbach and its principality to Bavaria in the Franco-Prussian treaty of alliance signed at Schönbrunn Palace on 15 December 1805 at the end of the Third Coalition. The act was confirmed by the 1815 Congress of Vienna; Prussia was compensated with the Bavarian duchy of Berg. Ansbach became the capital of the circle of Middle Franconia following the unification of Germany; at the time, it had a population of 12,635. Jewish families were resident in Ansbach from at least the end of the 18th century. They set up a Jewish Cemetery in the Ruglaender Strasse, which was vandalised and razed under the Nazi regime in the Kristallnacht. It was repaired in 1946, but it was damaged several times more. A plaque on the wall of the cemetery commemorates these events. The Jewish Congregation built its synagogue at No 3 Rosenbadstrasse, but it too was damaged by the SA, though it was not burnt down for fear of damaging the neighbouring buildings. It serves today as a "Symbolic House of God". A plaque in the entrance serves as a memorial to the synagogue and to Jewish residents who were murdered during the Holocaust. In 1940, at least 500 patients were deported from the Heil- und Pflegeanstalt Ansbach [Ansbach Medical and Nursing Clinic] to the extermination facilities Sonnenstein and Hartheim which were disguised as psychiatric institutions, as part of the Action T4 euthanasia action. They were gassed there. At the clinic in Ansbach itself, around 50 intellectually disabled children were injected with the drug Luminal and killed that way. A plaque was erected in their memory in 1988 in the local hospital at No. 38 Feuchtwangerstrasse. During World War II, a subcamp of Flossenbürg concentration camp was located here. Also during the Second World War the Luftwaffe and Wehrmacht had bases here. The nearby airbase was the home station for the Stab & I/KG53 (Staff & 1st Group of Kampfgeschwader 53) operating 38 Heinkel He 111 bombers. On 1 September 1939 this unit was one of the many that participated in the attack on Poland that started the war. All of its bridges were destroyed during the course of the war. During the Western Allied invasion of Germany in April 1945, the airfield was seized by the United States Third Army, and used by the USAAF 354th Fighter Group which flew P-47 Thunderbolts from the aerodrome (designated ALG R-82) from late April until the German capitulation on 7 May 1945. At the end of the war, 19-year-old student Robert Limpert tried to get the town to surrender to the US Forces without a fight. He was betrayed by Hitler Youth and was hung from the portal of the City Hall by the city's military commander, Col. (Oberst) Ernst Meyer. Several memorials to his heroic deed have been erected over the years, despite opposition from some residents — in the Ludwigskirche, in the Gymnasium Carolinum and at No 6 Kronenstrasse. After the Second World War, Ansbach belonged to the American Zone. The American Military authorities established a displaced persons (DP) camp in what used to be a sanatorium in what is today the Strüth quarter. Bachwoche Ansbach has been held in Ansbach since 1947. Since 1970, Ansbach has enlarged its municipal area by incorporating adjacent communities. Ansbach hosts several units of the U.S. armed forces, associated with German units under NATO. There are five separate U.S. installations: Shipton Kaserne, home to 412th Aviation Support Battalion, Katterbach Kaserne, formerly the home of the 1st Infantry Division's 4th Combat Aviation Brigade, also home of 501st M.I. Bn and 501st Avn Bn. which has been replaced by the 12th Combat Aviation Brigade as of 2006, as part of the 1st Infantry Division's return to Fort Riley, Kansas; Bismarck Kaserne, which functions as a satellite post to Katterbach, hosting their Post Theater, barracks, Von Steuben Community Center, Military Police, and other support agencies, Barton Barracks, home to the USAG Ansbach and Bleidorn Barracks, which has a library and housing, and Urlas, which hosts the Post Exchange as well as a housing area opened in 2010. Ansbach was also home to the headquarters of the 1st Armored Division (United States) from 1972 to the early 1990s. On 24 July 2016 a bomb was detonated in a restaurant in the city, killing only the bomber himself and injuring few people.
