Livor mortis starts in 20–30 minutes, but is usually not observable by the human eye until two hours after death. The size of the patches increases in the next three to six hours, with maximum lividity occurring between eight and twelve hours after death. The blood pools into the interstitial tissues of the body. The intensity of the color depends upon the amount of reduced haemoglobin in the blood. The discoloration does not occur in the areas of the body that are in contact with the ground or another object, in which capillaries are compressed. | what causes the lack of disoloration? | 52e96ecc64f95ad9df4739556f56bb29e852ed6d | en | capillaries are compressed |
Chinese culture (simplified Chinese: 中华文化; traditional Chinese: 中華文化; pinyin: Zhōnghuá wénhuà) is one of the world's oldest cultures, originating thousands of years ago. The area over which the culture prevails covers a large geographical region in East Asia and is extremely diverse and varying, with customs and traditions varying greatly between provinces, cities, and even towns as well. | Chinese culture prevails in what part of Asia? | 5ca0fdbb0fcc8ff20c1c98c59e9458508f72ca1c | en | East Asia |
During the Qing dynasty, China's last imperial dynasty, a dramatic shift of clothing occurred, examples of which include the cheongsam (or qipao in Mandarin). The clothing of the era before the Qing dynasty is referred to as Hanfu or traditional Han Chinese clothing. Many symbols such as phoenix have been used for decorative as well as economic purposes. Among them were the Banners (qí), mostly Manchu, who as a group were called Banner People (旗人 pinyin: qí rén). Manchu women typically wore a one-piece dress that retrospectively came to be known as the qípáo (旗袍, Manchu: sijigiyan or banner gown). The generic term for both the male and the female forms of Manchu dress, essentially similar garments, was chángpáo (長袍/长袍). The qipao fitted loosely and hung straight down the body, or flared slightly in an A-line. Under the dynastic laws after 1636, all Han Chinese in the banner system were forced to adopt the Manchu male hairstyle of wearing a queue as did all Manchu men and dress in Manchu qipao. However, the order for ordinary non-Banner Han civilians to wear Manchu clothing was lifted and only Han who served as officials were required to wear Manchu clothing, with the rest of the civilian Han population dressing however they wanted. Qipao covered most of the woman's body, revealing only the head, hands, and the tips of the toes. The baggy nature of the clothing also served to conceal the figure of the wearer regardless of age. With time, though, the qipao were tailored to become more form fitting and revealing. The modern version, which is now recognized popularly in China as the "standard" qipao, was first developed in Shanghai in the 1920s, partly under the influence of Beijing styles. People eagerly sought a more modernized style of dress and transformed the old qipao to suit their tastes. Slender and form fitting with a high cut, it had great differences from the traditional qipao. It was high-class courtesans and celebrities in the city that would make these redesigned tight fitting qipao popular at that time. In Shanghai it was first known as zansae or "long dress" (長衫—Mandarin Chinese: chángshān; Shanghainese: zansae; Cantonese: chèuhngsāam), and it is this name that survives in English as the "cheongsam". Most Han civilian men eventually voluntarily adopted Manchu clothing while Han women continued wearing Han clothing. Until 1911, the changpao was required clothing for Chinese men of a certain class, but Han Chinese women continued to wear loose jacket and trousers, with an overskirt for formal occasions. The qipao was a new fashion item for Han Chinese women when they started wearing it around 1925.The original qipao was wide and loose. As hosiery in turn declined in later decades, cheongsams nowadays have come to be most commonly worn with bare legs. | What is an example of a symbol? | e610711e1e4ab8921da602f460bd3762d3bf7fde | en | phoenix |
The Laptev Sea (Russian: мо́ре Ла́птевых, tr. more Laptevykh; Yakut: Лаптевтар байҕаллара) is a marginal sea of the Arctic Ocean. It is located between the northern coast of Siberia, the Taimyr Peninsula, Severnaya Zemlya and the New Siberian Islands. Its northern boundary passes from the Arctic Cape to a point with co-ordinates of 79°N and 139°E, and ends at the Anisiy Cape. The Kara Sea lies to the west, the East Siberian Sea to the east. | On which coast of Siberia is it located? | 8246250901aec633151f15ad6428a87954c37467 | en | northern |
The sea is named after the Russian explorers Dmitry Laptev and Khariton Laptev; formerly, it had been known under various names, the last being Nordenskiöld Sea (Russian: мо́ре Норденшёльда), after explorer Adolf Erik Nordenskiöld. The sea has a severe climate with temperatures below 0 °C (32 °F) over more than 9 months per year, low water salinity, scarcity of flora, fauna and human population, and low depths (mostly less than 50 meters). It is frozen most of the time, though generally clear in August and September. | What did Adolf Erik Nordenskiold discover? | cdaec4e56daf764d51499dc5600b5b4715309da5 | en | Nordenskiöld Sea |
Athletes with disabilities did compete in the Olympic Games prior to the advent of the Paralympics. The first athlete to do so was German American gymnast George Eyser in 1904, who had one artificial leg. Hungarian Karoly Takacs competed in shooting events in both the 1948 and 1952 Summer Olympics. He was a right-arm amputee and could shoot left-handed. Another disabled athlete to appear in the Olympics prior to the Paralympic Games was Lis Hartel, a Danish equestrian athlete who had contracted polio in 1943 and won a silver medal in the dressage event.The first organized athletic day for disabled athletes that coincided with the Olympic Games took place on the day of the opening of the 1948 Summer Olympics in London, United Kingdom. Jewish-German born Dr. Ludwig Guttmann of Stoke Mandeville Hospital, who had been helped to flee Nazi Germany by the Council for Assisting Refugee Academics (CARA) in 1939, hosted a sports competition for British World War II veteran patients with spinal cord injuries. The first games were called the 1948 International Wheelchair Games, and were intended to coincide with the 1948 Olympics. Dr. Guttman's aim was to create an elite sports competition for people with disabilities that would be equivalent to the Olympic Games. The games were held again at the same location in 1952, and Dutch and Israeli veterans took part alongside the British, making it the first international competition of its own kind. These early competitions, also known as the Stoke Mandeville Games, have been described as the precursors of the Paralympic Games. | How many artificial legs did Esyer have? | 60184cb268780854f89dc022bbf2ccf2c8eea2ac | en | one |
The Paralympics has grown from a small gathering of British World War II veterans in 1948 to become one of the largest international sporting events by the early 21st century. The Paralympics has grown from 400 athletes with a disability from 23 countries in 1960 to thousands of competitors from over 100 countries in the London 2012 Games. Paralympians strive for equal treatment with non-disabled Olympic athletes, but there is a large funding gap between Olympic and Paralympic athletes. | What is stopping the equal treatment of paralympians and non-disabled Olymipic athletes? | a15007a6abe948661d90357a85ea5642e376de39 | en | funding gap |
Because squirrels cannot digest cellulose, they must rely on foods rich in protein, carbohydrates, and fats. In temperate regions, early spring is the hardest time of year for squirrels because the nuts they buried are beginning to sprout (and thus are no longer available to eat), while many of the usual food sources have not yet become available. During these times, squirrels rely heavily on the buds of trees. Squirrels, being primarily herbivores, eat a wide variety of plants, as well as nuts, seeds, conifer cones, fruits, fungi, and green vegetation. Some squirrels, however, also consume meat, especially when faced with hunger. Squirrels have been known to eat small birds, young snakes, and smaller rodents, as well as bird eggs and insects. Indeed, some tropical squirrel species have shifted almost entirely to a diet of insects.Predatory behavior has been observed in various species of ground squirrels, in particular the thirteen-lined ground squirrel. For example, Bernard Bailey, a scientist in the 1920s, observed a thirteen-lined ground squirrel preying upon a young chicken. Wistrand reported seeing this same species eating a freshly killed snake. Whitaker examined the stomachs of 139 thirteen-lined ground squirrels and found bird flesh in four of the specimens and the remains of a short-tailed shrew in one; Bradley, examining the stomachs of white-tailed antelope squirrels, found at least 10% of his 609 specimens' stomachs contained some type of vertebrate, mostly lizards and rodents. Morgart observed a white-tailed antelope squirrel capturing and eating a silky pocket mouse. | what do squirrels eat other than plants? | 6866eaba0792c416291fb5323e7bccbd9452fe05 | en | nuts, seeds, conifer cones, fruits, fungi, and green vegetation |
Squirrels are generally small animals, ranging in size from the African pygmy squirrel at 7–10 cm (2.8–3.9 in) in length and just 10 g (0.35 oz) in weight, to the Laotian giant flying squirrel at 1.08 m (3 ft 7 in) in length and the Alpine marmot, which weighs from 5 to 8 kg (11 to 18 lb). Squirrels typically have slender bodies with bushy tails and large eyes. In general, their fur is soft and silky, though much thicker in some species than others. The coat color of squirrels is highly variable between—and often even within—species.In most squirrel species, the hind limbs are longer than the fore limbs, while all species have either four or five toes on each paw. The paws, which include an often poorly developed thumb, have soft pads on the undersides and versatile, sturdy claws for grasping and climbing. Tree squirrels, unlike most mammals, can descend a tree head-first. They do so by rotating their ankles 180 degrees, enabling the hind paws to point backward and thus grip the tree bark from the opposite direction.Squirrels live in almost every habitat, from tropical rainforest to semiarid desert, avoiding only the high polar regions and the driest of deserts. They are predominantly herbivorous, subsisting on seeds and nuts, but many will eat insects and even small vertebrates.As their large eyes indicate, squirrels have an excellent sense of vision, which is especially important for the tree-dwelling species. Many also have a good sense of touch, with vibrissae on their limbs as well as their heads.The teeth of sciurids follow the typical rodent pattern, with large incisors (for gnawing) that grow throughout life, and cheek teeth (for grinding) that are set back behind a wide gap, or diastema. The typical dental formula for sciurids is 1.0.1.31.0.1.3.Many juvenile squirrels die in the first year of life. Adult squirrels can have a lifespan of 5 to 10 years in the wild. Some can survive 10 to 20 years in captivity. Premature death may be caused when a nest falls from the tree, in which case the mother may abandon her young if their body temperature is not correct. Many such baby squirrels have been rescued and fostered by a professional wildlife rehabilitator until they could be safely returned to the wild, although the density of squirrel populations in many places and the constant care required by premature squirrels means that few rehabilitators are willing to spend their time doing this and such animals are routinely euthanized instead. | Squirrel fur can be aptly described as what? | 25414e162bd163849d9d3a147b22566df383b4d8 | en | soft and silky |
The living squirrels are divided into five subfamilies, with about 58 genera and some 285 species. The oldest squirrel fossil, Hesperopetes, dates back to the Chadronian (late Eocene, about 40–35 million years ago) and is similar to modern flying squirrels.A variety of fossil squirrels, from the latest Eocene to the Miocene, have not be assigned with certainty to any living lineage. At least some of these probably were variants of the oldest basal "protosquirrels" (in the sense that they lacked the full range of living squirrels' autapomorphies). The distribution and diversity of such ancient and ancestral forms suggest the squirrels as a group may have originated in North America.Apart from these sometimes little-known fossil forms, the phylogeny of the living squirrels is fairly straightforward. The three main lineages are the Ratufinae (Oriental giant squirrels), Sciurillinae and all other subfamilies. The Ratufinae contain a mere handful of living species in tropical Asia. The neotropical pygmy squirrel of tropical South America is the sole living member of the Sciurillinae. The third lineage, by far the largest, has a near-cosmopolitan distribution. This further supports the hypothesis that the common ancestor of all squirrels, living and fossil, lived in North America, as these three most ancient lineages seem to have radiated from there; if squirrels had originated in Eurasia, for example, one would expect quite ancient lineages in Africa, but African squirrels seem to be of more recent origin.The main group of squirrels also can be split into three subgroups, which yield the remaining subfamilies. The Sciurinae contains the flying squirrels (Pteromyini) and the Sciurini, which among others contains the American tree squirrels; the former have often been considered a separate subfamily, but are now seen as a tribe of the Sciurinae. The pine squirrels (Tamiasciurus), on the other hand, are usually included with the main tree squirrel lineage, but appear to be about as distinct as the flying squirrels; hence, they are sometimes considered a distinct tribe, Tamiasciurini.Two of the three subfamilies are of about equal size, containing between nearly 70 and 80 species each; the third is about twice as large. The Sciurinae contains arboreal (tree-living) squirrels, mainly of the Americas and to a lesser extent Eurasia. The Callosciurinae is most diverse in tropical Asia and contains squirrels that are also arboreal, but have a markedly different habitus and appear more "elegant", an effect enhanced by their often very colorful fur. The Xerinae—the largest subfamily—are made up from the mainly terrestrial (ground-living) forms and include the large marmots and the popular prairie dogs, among others, as well as the tree squirrels of Africa; they tend to be more gregarious than other squirrels, which do not usually live together in close-knit groups. | How many families are the squirrels divided into ? | e781b553649a703ecec4e5f323eda270a37c5ad8 | en | five |
The time in China follows a single standard time offset of UTC+08:00 (eight hours ahead of Coordinated Universal Time), despite China spanning five geographical time zones. The official national standard time is called Beijing Time (Chinese: 北京时间) domestically and China Standard Time (CST) internationally. Daylight saving time has not been observed since 1991.The special administrative regions (SARs) maintain their own time authorities, with standards called Hong Kong Time (香港時間) and Macau Standard Time (澳門標準時間). These have been equivalent to Beijing time since 1992. | What do the Chinese people call their official time standard? | 6997dadddad88f4050e708367c306d7c59cdffab | en | Beijing Time |

Inhabiting tropical regions, the deer have no seasonal rut, and mating can take place at any time of year; this behaviour is retained by populations introduced to temperate countries. Males have short antlers, which can regrow, but they tend to fight for territory with their "tusks" (downward-pointing canine teeth). The presence of these "tusks" is otherwise unknown in native British wild deer and can be discriminatory when trying to differentiate a muntjac from an immature native deer, although water deer also have visible tusks; however, they are much less widespread. | What are canine teeth that point down called? | 78ca588fa927f5bb2dde88e1db3bf9bf5b36486e | en | tusks |

Muntjac are of great interest in evolutionary studies because of their dramatic chromosome variations and the recent discovery of several new species. The Indian muntjac (M. muntjak) is the mammal with the lowest recorded chromosome number: The male has a diploid number of 7, the female only 6 chromosomes. Reeves's muntjac (M. reevesi), in comparison, has a diploid number of 46 chromosomes.The genus Muntiacus has 12 recognized species: | What species is of great interested currently? | 1556ddb4a90fb60760b05213bf916841e0ff6ff3 | en | Muntjac |
Muntjacs ( MUN-jahk), also known as barking deer and Mastreani deer, are small deer of the genus Muntiacus native to south Asia. Muntjacs are thought to have begun appearing 15–35 million years ago, with remains found in Miocene deposits in France, Germany and Poland. It is listed as Least Concern by the IUCN. | When did Muntjacs begin appearing? | 10ee1845582c9a79d0673a684e1726cd58c50038 | en | 15–35 million years ago |
Benghazi continues to hold institutions and organizations normally associated with a national capital city, such as the country's parliament, national library, and the headquarters of Libyan Airlines, the national airline, and of the National Oil Corporation. This creates a constant atmosphere of rivalry and sensitivities between Benghazi and Tripoli, and between Cyrenaica and Tripolitania. The population was 670,797 at the 2006 census.On 15 February 2011, an uprising against the government of Muammar Gaddafi occurred in the city. The revolts spread by 17 February to Bayda, Tobruk, Ajdabya, Al Marj in the East and Zintan, Zawiya in the West, calling for the end of the Gaddafi Regime. Benghazi was taken by Gaddafi opponents on 21 February, who founded the National Transitional Council. On 19 March, the city was the site of the turning point of the Libyan Civil War, when the Libyan Army attempted to score a decisive victory against the NTC by attacking Benghazi, but was forced back by local resistance and intervention from the French Air Force authorized by UNSC Resolution 1973 to protect civilians, allowing the rebellion to continue. | What was the population in 2006? | 73636ffbbf90b9ff294f7f3a279a9742066e9ea4 | en | 670,797 |
In 1902 he graduated from Vilnius Military Academy. Larka participated in the Russo-Japanese War and graduated from the Imperial Nicholas Military Academy in 1912. He participated in World War I fighting on the Eastern front against the German Empire, including fighting in East Prussia, Poland and Romania. Larka became the first Minister of War of Republic of Estonia; in March he achieved rank of Major General. In 1918, during the German occupation, he participated in organising the Defence League. After the start of the Estonian Liberation War in 1918, Larka soon moved from position of Minister of War to Chief of Staff. In February 1919 he became the aide of the Minister of War and held that position to the beginning of 1925. In that position his job was to organize mobilization and actions of reserve units. After the war he also organized demobilization. He retired in 1925 because of health issues. In 1930 he became official leader of the League of Liberators and was their candidate in the April 1934 presidential elections. But on 12 March 1934, as it seemed likely that Larka would be elected, Konstantin Päts and Johan Laidoner made a coup d'état in order to prevent him from winning the elections. The elections were postponed indefinitely, Larka and about 400 of his closest supporters were imprisoned and authoritarian rule was established. Larka was in prison twice (1934-1935 and 1935-1937). In 1940 the Soviet occupation authorities arrested Larka; he died in imprisonment in 1943. | Who was the League of Liberators presidential candidate during April 1934 elections in Estonia? | 3c7d1a724da56fe9f8a596194931cf033531bd6b | en | Larka |

Ernesto Sabato (June 24, 1911 – April 30, 2011) was an Argentine novelist, essayist, painter and physicist. According to the BBC he "won some of the most prestigious prizes in Hispanic literature" and "became very influential in the literary world throughout Latin America". Upon his death El País dubbed him the "last classic writer in Argentine literature".Sabato was distinguished by his bald pâté and brush moustache and wore tinted spectacles and open-necked shirts. He was born in Rojas, a small town in Buenos Aires Province. Sabato began his studies at the Colegio Nacional de La Plata. He then studied physics at the Universidad Nacional de La Plata, where he earned a PhD. He then attended the Sorbonne in Paris and worked at the Curie Institute. After World War II, he lost interest in science and started writing. | When was Ernesto Sabato born? | 30b8985390d9e21d8e8c09e62b96295251828f0f | en | June 24, 1911 |

It was in that month that the Empress of Russia died and her successor Paul, who detested the Zubovs and had other plans for the army, ordered the troops to retreat back to Russia. This reversal aroused the frustration and enmity of the powerful Zubovs and other officers who took part in the campaign: many of them would be among the conspirators who arranged Paul's murder five years later. | How many years later was Paul killed? | 436d67b405c41c888303fb83362da24be17f09b7 | en | five years |
Thus, as he began recruiting supporters for an attack on slaveholders, Brown was joined by "General Tubman", as he called her. Her knowledge of support networks and resources in the border states of Pennsylvania, Maryland and Delaware was invaluable to Brown and his planners. Although other abolitionists like Frederick Douglass and William Lloyd Garrison did not endorse his tactics, Brown dreamed of fighting to create a new state for freed slaves, and made preparations for military action. After he began the first battle, he believed, slaves would rise up and carry out a rebellion across the south. He asked Tubman to gather former slaves then living in present-day Southern Ontario who might be willing to join his fighting force, which she did.On May 8, 1858, Brown held a meeting in Chatham, Ontario, where he unveiled his plan for a raid on Harpers Ferry, Virginia. When word of the plan was leaked to the government, Brown put the scheme on hold and began raising funds for its eventual resumption. Tubman aided him in this effort, and with more detailed plans for the assault.Tubman was busy during this time, giving talks to abolitionist audiences and tending to her relatives. In the autumn of 1859, as Brown and his men prepared to launch the attack, Tubman could not be contacted. When the raid on Harpers Ferry took place on October 16, Tubman was not present. Some historians believe she was in New York at the time, ill with fever related to her childhood head injury. Others propose she may have been recruiting more escaped slaves in Ontario, and Kate Clifford Larson suggests she may have been in Maryland, recruiting for Brown's raid or attempting to rescue more family members. Larson also notes that Tubman may have begun sharing Frederick Douglass's doubts about the viability of the plan.The raid failed; Brown was convicted of treason and hanged in December. His actions were seen by abolitionists as a symbol of proud resistance, carried out by a noble martyr. Tubman herself was effusive with praise. She later told a friend: "[H]e done more in dying, than 100 men would in living." | Harriet Tubman suffered what type of injury? | 10fa3bc557343eb44ce5e9ec605e1fde70bb9881 | en | childhood head injury |
Tubman and her brothers, Ben and Henry, escaped from slavery on September 17, 1849. Tubman had been hired out to Dr. Anthony Thompson, who owned a large plantation in an area called Poplar Neck in neighboring Caroline County; it is likely her brothers labored for Thompson as well. Because the slaves were hired out to another household, Eliza Brodess probably did not recognize their absence as an escape attempt for some time. Two weeks later, she posted a runaway notice in the Cambridge Democrat, offering a reward of up to 100 dollars for each slave returned. Once they had left, Tubman's brothers had second thoughts. Ben may have just become a father. The two men went back, forcing Tubman to return with them.Soon afterward, Tubman escaped again, this time without her brothers. Beforehand, she tried to send word to her mother of her plans. She sang a coded song to Mary, a trusted fellow slave, that was a farewell. "I'll meet you in the morning," she intoned, "I'm bound for the promised land." While her exact route is unknown, Tubman made use of the network known as the Underground Railroad. This informal but well-organized system was composed of free and enslaved blacks, white abolitionists, and other activists. Most prominent among the latter in Maryland at the time were members of the Religious Society of Friends, often called Quakers. The Preston area near Poplar Neck in Caroline County contained a substantial Quaker community, and was probably an important first stop during Tubman's escape. From there, she probably took a common route for fleeing slaves – northeast along the Choptank River, through Delaware and then north into Pennsylvania. A journey of nearly 90 miles (145 kilometers), her traveling by foot would have taken between five days and three weeks.Tubman had to travel by night, guided by the North Star, and trying to avoid slave catchers eager to collect rewards for fugitive slaves. The "conductors" in the Underground Railroad used deceptions for protection. At an early stop, the lady of the house instructed Tubman to sweep the yard so as to seem to be working for the family. When night fell, the family hid her in a cart and took her to the next friendly house. Given her familiarity with the woods and marshes of the region, Tubman during the day likely hid in these locales. Tubman only later described her routes because other fugitive slaves used them. | What was different about Tubmans last escape? | 91d1d60b4a6b5c2a631e0d384e5fa7d764afac7b | en | without her brothers |
While a popular legend persists about a reward of US$40,000 for Tubman's capture, this is a manufactured figure. In 1868, in an effort to drum up support for Tubman's claim for a Civil War military pension, a former abolitionist named Salley Holley wrote an article claiming US$40,000 "was not too great a reward for Maryland slaveholders to offer for her". Such a high reward would have garnered national attention, especially at a time when a small farm could be purchased for a mere US$400. No such reward has been found in period newspapers. (The federal government offered $25,000 for the capture of each of John Wilkes Booth's co-conspirators in Lincoln's assassination.) A reward offering of US$12,000 has also been claimed, though no documentation exists for that figure either. Catherine Clinton suggests that the US$40,000 figure may have been a combined total of the various bounties offered around the region.Despite the best efforts of the slaveholders, Tubman was never captured, and neither were the fugitives she guided. Years later, she told an audience: "I was conductor of the Underground Railroad for eight years, and I can say what most conductors can't say – I never ran my train off the track and I never lost a passenger." One of her last missions into Maryland was to retrieve her aging parents. Her father, Ben, had purchased Rit, her mother, in 1855 from Eliza Brodess for 20 dollars. But even when they were both free, the area became hostile to their presence. Two years later, Tubman received word that her father had harbored a group of eight escaped slaves, and was at risk of arrest. She traveled to the Eastern Shore and led them north to St. Catharines, Ontario, where a community of former slaves (including Tubman's brothers, other relatives, and many friends) had gathered. | What did Catherine Clinton suggest? | f29b652d57996627829a1cb2940bdc7a99cfde8f | en | US$40,000 figure may have been a combined total of the various bounties offered around the region |
By the middle of 1982, Iraq was mostly expelled from Iranian territory, having lost nearly all the gains they made during the invasion in 1980. Saddam Hussein used the Israeli invasion of Lebanon as an excuse to seek an end to the war and send the Palestinians aid. Seyyed Ruhollah Khomeini rejected peace offers from Baghdad and began preparing to expand into Iraq.Initially, some in Tehran rejected the idea of invasion, claiming that such a move would undermine Iran's moral standing and diminish the sympathy gained by Muslim countries as the result of Saddam's invasion. These individuals were backed by Iranian army officers. However, these voices were shut out by pro-war voices in Tehran, who claimed that Baghdad could be defeated with the use of zealous fighters and invoking anti-government sentiment amongst Iraq's Shia. At the time, the Iranian population experienced a euphoria of victory. Thus, plans for invasion included both the silencing of Iraqi artillery that was shelling civilian border towns, destroying the Iraqi Third Corps, and the seizure of Basra (Iraq's third largest city).

Iraq had concentrated three armoured divisions, the 3rd, 9th, and 10th, as a counter-attack force to attack any penetrations. They were successful in defeating the Iranian breakthroughs, but suffered heavy losses. The 9th Armoured Division in particular had been practically wiped out, lead to it being disbanded, and was never reformed. | What Division was disbanded and did not form again? | c5caf816f70a5dd1be7a08eae18d3092cccb7acb | en | 9th Armoured Division |
Over 100,000 Revolutionary Guards and Basij volunteer forces charged towards the Iraqi lines. The Iraqi troops had entrenched themselves in formidable defences, and had set up a network of bunkers, artillery positions and rows of tanks in hull-down position. Iraqi morale had gone up, as they were fighting to defend their own nation. Saddam had also more than doubled the size of the Iraqi army, from 200,000 soldiers (12 divisions and 3 independent brigades) to 500,000 (23 divisions and nine brigades).Among the regular Iranian formations that were charging were the 16th (M60A1 MBTs), 88th (M47 and M48A5 MBTs), and 92nd (Chieftain Mk 3/5 MBTs) Armoured Divisions, along with the 21st, 40th and 77th Mechanized Divisions. Iran's Revolutionary Guards also used the T-55 tanks they had captured in earlier battles.Basiji child-soldiers were sent forth to bodily clear the Iraqi minefields and allow the Revolutionary Guards to advance. The Basij also launched human wave attacks on Iraqi positions, inspired before battle by tales of Ashura, the Battle of Karbala, and the glory of martyrdom. Sometimes an actor (usually an older soldier) would play the part of Imam Hossein and, on a white horse, gallop along the lines, providing the inexperienced soldiers a vision of "the hero who would lead them into their fateful battle before they met their God". The "martyrs" had signed "Passports to Paradise" (as admission forms to the Basij were nicknamed), received a week of basic military training by the Revolutionary Guard, and were sent directly to the front lines. The human wave assaults, often with no support from other military branches due to rivalry with the remnants of the former Imperial Iranian Army, were met with crushing artillery, rocket, and tank fire from Iraq's defence that caused massive losses to the Iranian side.By 16 July the Iranians had in their first attack succeeded in overrunning the forward Iraqi defence lines right at the border, gained in their deepest penetration 16 km (9.9 mi) inside Iraq and claimed to have captured 288 square kilometers (180 square miles) of Iraqi territory albeit with a great deal of casualties. The Iranian forces had penetrated as far as the Kutayba river, a tributary to the Shatt Al Arab river, but failed to cross it. However, the Iranian forces came to a halt as the Iraqis stopped the main Iranian attack and launched frontal and flanking counter-attacks supported by air strikes from fighter-bombers that pushed the Iranians back to within 4 kilometers (2,5 miles) from the border.The Iraqis used their Mi-25 helicopters, along with Gazelle helicopters armed with HOT missiles against columns of Iranian mechanised infantry and tanks. These "hunter-killer" teams of helicopters, which had been formed with the help of East German advisors, proved to be very costly for Iranians. Aerial dogfights occurred between Iraqi MiG's and Iranian Phantom's. During this battle, the Iraqis also made first significant use of chemical weapons, contributing to their successes on the battlefield.[63] During this instance, the Iraqis used large amounts of non-lethal tear gas to disrupt the offensive, throwing an entire attacking Iranian division into chaos.On 21 July, the Iranians tried again with a second thrust and managed to penetrate through the Iraqi defence lines once again. However, only 13 km (8.1 mi) from Basra, the poorly equipped Iranian forces were surrounded on three sides and cut-off from Iranian logistics and supply units by Iraqis who counter-attacked with heavy weaponry. The Iraqi counter-attacks once again pushed the Iranians back to their starting point where fighting slowed to a stalemate. Only a last-minute attack by Iranian Cobra helicopters stopped the Iraqis from routing the Iranians completely. Three more similar Iranian attacks occurred around the Khorramshar-Baghdad road area towards the end of the month, but none were significantly successful.The final Iranian thrust came on 1 August, when in a last ditch effort, the Iranians attacked Iraqi defence lines at the border, taking a sliver of land before fighting died down on 3 August. | Who helped Iraqis use mi-25 and gazelle helicopters against the Iranian military? | 8d77f969bf4e320eaae79573537340d11872f150 | en | East German advisors |

Anning's discoveries became key pieces of evidence for extinction. Georges Cuvier had argued for the reality of extinction in the late 1790s based on his analysis of fossils of mammals such as mammoths. Nevertheless, until the early 1820s it was still believed by many scientifically literate people that just as new species did not appear, so existing ones did not become extinct—in part because they felt that extinction would imply that God's creation had been imperfect; any oddities found were explained away as belonging to animals still living somewhere in an unexplored region of the Earth. The bizarre nature of the fossils found by Anning, — some, such as the plesiosaur, so unlike any known living creature — struck a major blow against this idea.The ichthyosaurs, plesiosaurs, and pterosaur she found, along with the first dinosaur fossils which were discovered by Gideon Mantell and William Buckland during the same period, showed that during previous eras the Earth was inhabited by creatures very different from those living today, and provided important support for another controversial suggestion of Cuvier's: that there had been an "age of reptiles" when reptiles rather than mammals had been the dominant form of animal life. This phrase became popular after the publication in 1831 of a paper by Mantell entitled "The Age of Reptiles" that summarised the evidence that there had been an extended geological era when giant reptiles has swarmed the land, air, and sea. These discoveries also played a key role in the development of a new discipline of geohistorical analysis within geology in the 1820s that sought to understand the history of the Earth by using evidence from fossils to reconstruct extinct organisms and the environments in which they lived. This discipline eventually came to be called palaeontology. Illustrations of scenes from "deep time" (now known as palaeoart), such as Henry De la Beche's ground-breaking painting Duria Antiquior, helped convince people that it was possible to understand life in the distant past. De la Beche had been inspired to create the painting by a vivid description of the food chain of the Lias by William Buckland that was based on analysis of coprolites. The study of coprolites, pioneered by Anning and Buckland, would prove to be a valuable tool for understanding ancient ecosystems. | Whose discoveries were known as evidence for extinction? | 9c1c3789289002afe2c33f0a0a0c71c62449c50d | en | Anning's |

One of the most cited scholars in history, Chomsky has influenced a broad array of academic fields. He is widely recognized as a paradigm shifter who helped spark a major revolution in the human sciences, contributing to the development of a new cognitivistic framework for the study of language and the mind. In addition to his continued scholarly research, he remains a leading critic of U.S. foreign policy, neoliberalism and contemporary state capitalism, the Israeli–Palestinian conflict, and mainstream news media.

Until the 1970s, Mary Shelley was known mainly for her efforts to publish her husband's works and for her novel Frankenstein, which remains widely read and has inspired many theatrical and film adaptations. Recent scholarship has yielded a more comprehensive view of Mary Shelley's achievements. Scholars have shown increasing interest in her literary output, particularly in her novels, which include the historical novels Valperga (1823) and Perkin Warbeck (1830), the apocalyptic novel The Last Man (1826), and her final two novels, Lodore (1835) and Falkner (1837). Studies of her lesser-known works, such as the travel book Rambles in Germany and Italy (1844) and the biographical articles for Dionysius Lardner's Cabinet Cyclopaedia (1829–1846), support the growing view that Mary Shelley remained a political radical throughout her life. Mary Shelley's works often argue that cooperation and sympathy, particularly as practised by women in the family, were the ways to reform civil society. This view was a direct challenge to the individualistic Romantic ethos promoted by Percy Shelley and the Enlightenment political theories articulated by her father, William Godwin. | In what year was Valperga made? | a6fb40bad3aaddab39849d7f1194f46ed14a48ca | en | 1823 |

After the Treaty of Paris in 1763, which deprived France of almost all her possessions in the Americas other than Guiana and a few islands, Louis XV sent thousands of settlers to Guiana who were lured there with stories of plentiful gold and easy fortunes to be made. Instead they found a land filled with hostile natives and tropical diseases. One and a half years later only a few hundred survived. These fled to three small islands which could be seen off shore and named them the Iles de Salut (or "Islands of Salvation"). The largest was called Royal Island, another St. Joseph (after the patron saint of the expedition), and the smallest of the islands, surrounded by strong currents, Île du Diable (the infamous "Devil's Island"). When the survivors of this ill-fated expedition returned home, the terrible stories they told of the colony left a lasting impression in France. | What was the land filled with? | f21d0e2102f2c61006944d859703bb10bee814cc | en | hostile natives and tropical diseases |

The infamous penal colonies, including Devil's Island, were gradually phased out and then formally closed in 1951.

Dutch architect & Benedictine monk Dom Hans van der Laan gave the name plastic number (Dutch: het plastische getal) to this number in 1928. In 1924, four years prior to van der Laan's christening of the number's name, French engineer Gérard Cordonnier had already discovered the number and referred to it as the radiant number (French: le nombre radiant). Unlike the names of the golden ratio and silver ratio, the word plastic was not intended by van der Laan to refer to a specific substance, but rather in its adjectival sense, meaning something that can be given a three-dimensional shape. This, according to Richard Padovan, is because the characteristic ratios of the number, 3/4 and 1/7, relate to the limits of human perception in relating one physical size to another. Van der Laan designed the 1967 St. Benedictusberg Abbey church to these plastic number proportions.The plastic number is also sometimes called the silver number, a name given to it by Midhat J. Gazalé and subsequently used by Martin Gardner, but that name is more commonly used for the silver ratio 1 + √2, one of the ratios from the family of metallic means first described by Vera W. de Spinadel in 1998.Donald E.

A group of Berbers Andalusians exiles led by Abu Hafs Umar al-Iqritishi conquered Crete sometime c. 824 or in the year 827/828, and established an independent Islamic state. The Byzantines launched a campaign that took most of the island back in 842 and 843 under Theoktistos, but the reconquest was not completed and was soon reversed. Later attempts by the Byzantine Empire to recover the island failed, and for the approximately 135 years of its existence, the emirate was one of the major foes of Byzantium. Crete commanded the sea lanes of the Eastern Mediterranean and functioned as a forward base and haven for Muslim corsair fleets that ravaged the Byzantine-controlled shores of the Aegean Sea. The emirate's internal history is less well-known, but all accounts point to considerable prosperity deriving not only from piracy but also from extensive trade and agriculture.

Cretan piracy reached another high in the 930s and 940s, devastating southern Greece, Athos, and the western coasts of Asia Minor. As a result, Emperor Constantine VII (r. 913–959) sent another expedition in 949. This too was routed in a surprise attack, a defeat which Byzantine chroniclers ascribe to the incompetence and inexperience of its leader, the eunuch chamberlain Constantine Gongyles. Constantine VII did not give up, and during the last years of his reign he began preparing another expedition. It would be carried out under his successor, Romanos II (r. 959–963), who entrusted its leadership to the capable general Nikephoros Phokas. At the head of a huge fleet and army, Phokas sailed in June or July 960, landed on the island, and defeated the initial Muslim resistance. A long siege of Chandax followed, which dragged over the winter into 961, when the city was stormed on 6 March.The city was pillaged, and its mosques and walls were torn down. Muslim inhabitants were either killed or carried off into slavery, while the island's last emir Abd al-Aziz ibn Shu'ayb (Kouroupas) and his son al-Numan (Anemas) were taken captive and brought to Constantinople, where Phokas celebrated a triumph. The island was converted into a Byzantine theme,traces of the muslim presence were destroyed as much as possible, and the remaining Muslims were converted to Christianity by missionaries like Nikon "the Metanoeite". Among the converts was the prince Anemas, who entered Byzantine service and fell at Dorostolon, in the war of 970–971 against the Rus'. | What happened to the Muslim inhabitants? | 98131efc5d6dbc6a9d9be39c08996f033c35ff78 | en | killed or carried off into slavery |
In the early 870s, the Cretan raids reached a new intensity: their fleets, often commanded by Byzantine renegades, ranged the Aegean and further afield, reaching the Dalmatian coasts. On one occasion c. 873 a Cretan fleet under the renegade Photios even penetrated into the Marmara Sea and unsuccessfully attacked Proconnesos; the first time since the Second Arab Siege of Constantinople in 717–718 that a Muslim fleet had come so close to the Byzantine capital. On its return however, it suffered a heavy defeat at the hands of the new Byzantine admiral, Niketas Ooryphas, at the Battle of Kardia. Shortly after, Ooryphas once again defeated the Cretans at the Gulf of Corinth and took many prisoners, whom he tortured extensively in revenge for their raids. At about the same time, the Muslim fleet of Tarsus led by Yazaman al-Khadim was destroyed in a raid against Euripos. These Byzantine victories apparently led to a temporary truce, and it appears that the Cretan emir Saïpes (Shu'ayb ibn Umar) was obliged to pay tribute to Byzantium for about a decade.Raids resumed soon after, in which the Cretans were joined by North African and Syrian fleets. The Peloponnese in particular suffered considerably from their raids, but also Euboea and the Cyclades: the islands of Patmos, Karpathos and nearby Sokastro came under Cretan control, and Cretan rule extended as far north as Aegina in the Saronic Gulf, and to Elafonisos and Cythera off the southern coast of the Peloponnese; the great Cycladic island of Naxos, probably along with the neighbouring islands of Paros and Ios, was forced to pay them the poll-tax (jizya). As the Muslim presence left generally few material or literary traces, the list of islands at one time controlled or occupied by them could well be longer. Nevertheless, the impact of this new wave of Arab raids was felt across the Aegean, where some islands were deserted altogether, and elsewhere coastal sites were abandoned for better protected inland locations. Athens may have been occupied in c. 896–902, and in 904, a Syrian fleet led by Leo of Tripoli sacked the Byzantine Empire's second city, Thessalonica. The Arabs of Crete co-operated closely with their Syrian counterparts, who often used Crete as a base or a stop-over, as during Leo of Tripoli's fleet return from Thessalonica, when many of the over 20,000 Thessalonian captives were sold or gifted as slaves in Crete. Likewise, the Cretan emirate received strong support from the Tulunid governors of Egypt (868–905), but their Ikhshidid successors neglected aid to Crete. In 911, another large-scale Byzantine expedition of well over 100 ships was launched against Crete, headed by the admiral Himerios, but it was forced to leave the island after a few months. On its return journey, Himerios' fleet was destroyed in battle off Chios by the Syrian fleet. | When did Syrian flee sack Thessalonica? | 0dc3762d2b9a6726b001181a3a8c9e57c32906cd | en | in 904 |
A popular twist on Internet-based philanthropy is the use of peer-to-peer lending for charitable purposes. Kiva pioneered this concept in 2005, offering the first web-based service to publish individual loan profiles for funding. Kiva raises funds for local intermediary microfinance organizations which post stories and updates on behalf of the borrowers. Lenders can contribute as little as $25 to loans of their choice, and receive their money back as borrowers repay. Kiva falls short of being a pure peer-to-peer charity, in that loans are disbursed before being funded by lenders and borrowers do not communicate with lenders themselves. However, the recent spread of cheap Internet access in developing countries has made genuine peer-to-peer connections increasingly feasible. In 2009 the US-based nonprofit Zidisha tapped into this trend to offer the first peer-to-peer microlending platform to link lenders and borrowers across international borders without local intermediaries. Inspired by interactive websites such as Facebook and eBay, Zidisha's microlending platform facilitates direct dialogue between lenders and borrowers and a performance rating system for borrowers. Web users worldwide can fund loans for as little as a dollar. | What was the name of the US-based nonprofit organization? | d01d83df8d15e8300a80ca94cbcebc5c6a14c691 | en | Zidisha |
Governments are also getting online. Some countries, such as those of Cuba, Iran, North Korea, Myanmar, the People's Republic of China, and Saudi Arabia use filtering and censoring software to restrict what people in their countries can access on the Internet. In the United Kingdom, they also use software to locate and arrest various individuals they perceive as a threat.

The Internet is a relatively new phenomenon. As Robert Darnton wrote, it is a revolutionary change that "took place yesterday, or the day before, depending on how you measure it." The Internet developed from the ARPANET, dating back to 1969; as a term it was coined in 1974. The World Wide Web as we know it was shaped in the mid-1990s, when graphical interface and services like email became popular and reached wider (non-scientific and non-military) audiences and commerce. Internet Explorer was first released in 1995; Netscape a year earlier. Google was founded in 1998. Wikipedia was founded in 2001. Facebook, MySpace, and YouTube in the mid-2000s. Web 2.0 is still emerging. The amount of information available on the net and the number of Internet users worldwide has continued to grow rapidly. The term 'digital sociology' is now becoming increasingly used to denote new directions in sociological research into digital technologies since Web 2.0. | The World Wide Web can trace it's origins to what development in the late 1960's? | b8e433330f2cc4a9c454e76198ba699ac12de62e | en | ARPANET |
While much has been written of the economic advantages of Internet-enabled commerce, there is also evidence that some aspects of the Internet such as maps and location-aware services may serve to reinforce economic inequality and the digital divide.

The Poseidon Adventure is a 1972 American disaster film directed by Ronald Neame, produced by Irwin Allen, and based on Paul Gallico's eponymous 1969 novel. It features an ensemble cast, including five Academy Award winners: Gene Hackman; Ernest Borgnine; Jack Albertson; Shelley Winters; and Red Buttons. Parts of the movie were filmed aboard the RMS Queen Mary. The plot centers on the fictional SS Poseidon, an aged luxury liner on her final voyage from New York City to Athens before being sent to the scrapyard. On New Year's Eve, she is overturned by a tsunami. Passengers and crew are trapped inside, and a rebellious preacher attempts to lead a small group of survivors to safety.It is in the vein of other all-star disaster films of the early-mid 1970s such as Airport (1970), Earthquake (1974), and The Towering Inferno (1974). By the end of 1974, it was regarded as a widely successful film. The film won two Academy Awards, a Golden Globe Award, a British Academy Film Award, and a Motion Picture Sound Editors Award. A sequel, Beyond the Poseidon Adventure (1979), also based on a novel by Gallico, was a critical and commercial failure. | What is one award that Jack Albertson has won? | 71eb796c1c7a19ec83a6dbfdfe09ded69ca2a169 | en | Academy Award |

Following their victory at the Battle of Heliopolis in July 640, and the subsequent capitulation of Alexandria in November 641, Arab troops had taken over what was the Roman province of Egypt. The newly installed Byzantine Emperor Constans II was determined to re-take the land, and ordered a large fleet to carry troops to Alexandria. These troops, under Manuel, took the city by surprise from its small Arab garrison towards the end of 645 in an amphibious attack. In 645 the Byzantine thus temporarily won Alexandria back. Amr at the time may have been in Mecca, and was quickly recalled to take command of the Arab forces in Egypt.The battle took place at the small fortified town of Nikiou (Coptic: ⲡϣⲁϯ Pashati), about two-thirds of the way from Alexandria to Fustat, with the Arab forces numbering around 15,000, against a smaller Byzantine force. The Arabs prevailed, and the Byzantine forces retreated in disarray, back to Alexandria.Although the Byzantines closed the gates against the pursuing Arabs, the city of Alexandria eventually fell to the Arabs, who stormed the city sometime in the summer of that year. The defeat of Manuel's forces marked the last attempt by the Byzantine Empire to recapture Egypt for some 500 years, with only Emperor Manuel I Komnenos sending a failed expedition there in the 12th century.Then Amr ibn al-A'as wrote back to the Caliph: | Where was a huge group of troops sent to to reclaim land? | 16f91d383d1176bc30b065410c5e2f9147fbe099 | en | Alexandria |

Charles's English parliament enacted laws known as the Clarendon Code, designed to shore up the position of the re-established Church of England. Charles acquiesced to the Clarendon Code even though he favoured a policy of religious tolerance. The major foreign policy issue of his early reign was the Second Anglo-Dutch War. In 1670, he entered into the Treaty of Dover, an alliance with his first cousin King Louis XIV of France. Louis agreed to aid him in the Third Anglo-Dutch War and pay him a pension, and Charles secretly promised to convert to Catholicism at an unspecified future date. Charles attempted to introduce religious freedom for Catholics and Protestant dissenters with his 1672 Royal Declaration of Indulgence, but the English Parliament forced him to withdraw it. In 1679, Titus Oates's revelations of a supposed Popish Plot sparked the Exclusion Crisis when it was revealed that Charles's brother and heir, James, Duke of York, was a Catholic. The crisis saw the birth of the pro-exclusion Whig and anti-exclusion Tory parties. Charles sided with the Tories, and, following the discovery of the Rye House Plot to murder Charles and James in 1683, some Whig leaders were executed or forced into exile. Charles dissolved the English Parliament in 1681, and ruled alone until his death on 6 February 1685. He was received into the Catholic Church on his deathbed. | During Charles's reign, what were the collective laws issued by parliament called? | 9b71b77928ff5e3231d842594577fae974f9ed01 | en | the Clarendon Code |

Rikyū was born in Sakai in present-day Osaka Prefecture. His father was a warehouse owner named Tanaka Yohei (田中与兵衛), who later in life also used the family name Sen, and his mother was Gesshin Myōchin (月岑妙珎). His childhood name was Yoshiro.As a young man, Rikyū studied tea under the townsman of Sakai named Kitamuki Dōchin (1504–62), and at nineteen, through Dōchin's introduction, he began to study tea under Takeno Jōō, who is also associated with the development of the wabi aesthetic in tea ceremony. He is believed to have received the Buddhist name Sōeki (宗易) from the Rinzai Zen priest Dairin Sōtō (1480–1568) of Nanshūji temple in Sakai. He married a woman known as Hōshin Myōju (d. 1577) around when he was twenty-one. Rikyū also underwent Zen training at Daitoku-ji temple in Kyoto.

Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular type e.g., water, protein, fats (or lipids), hydroxylapatite (in bones), carbohydrates (such as glycogen and glucose) and DNA. In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal human gastrointestinal tract. | Water, fat, muscles and bones are found throughout the body and can be classified and analyzed as what? | 11798497e1232cceea799152dbbb6e535961e580 | en | tissue type |

Enceladus is one of the major inner satellites of Saturn along with Dione, Tethys, and Mimas. It orbits at 238,000 km from Saturn's center and 180,000 km from its cloud tops, between the orbits of Mimas and Tethys. It orbits Saturn every 32.9 hours, fast enough for its motion to be observed over a single night of observation. Enceladus is currently in a 2:1 mean-motion orbital resonance with Dione, completing two orbits around Saturn for every one orbit completed by Dione. This resonance maintains Enceladus's orbital eccentricity (0.0047), which is known as a forced eccentricity. This non-zero eccentricity results in tidal deformation of Enceladus. The dissipated heat resulting from this deformation is the main heating source for Enceladus's geologic activity. Enceladus orbits within the densest part of Saturn's E ring, the outermost of its major rings, and is the main source of the ring's material composition.Like most of Saturn's larger satellites, Enceladus rotates synchronously with its orbital period, keeping one face pointed toward Saturn. Unlike Earth's Moon, Enceladus does not appear to librate more than 1.5° about its spin axis. However, analysis of the shape of Enceladus suggests that at some point it was in a 1:4 forced secondary spin–orbit libration. This libration could have provided Enceladus with an additional heat source. | The shape of Enceladus suggested that it was involved in a voluntary spin orbit liberation, or a forced spin orbit libration? | e6187416d5732a3e466bb172e20f6cce747a5867 | en | forced |
Images taken by Cassini during the flyby on July 14, 2005, revealed a distinctive, tectonically deformed region surrounding Enceladus's south pole. This area, reaching as far north as 60° south latitude, is covered in tectonic fractures and ridges. The area has few sizable impact craters, suggesting that it is the youngest surface on Enceladus and on any of the mid-sized icy satellites; modeling of the cratering rate suggests that some regions of the south polar terrain are possibly as young as 500,000 years or less. Near the center of this terrain are four fractures bounded by ridges, unofficially called "tiger stripes". They appear to be the youngest features in this region and are surrounded by mint-green-colored (in false color, UV–green–near IR images), coarse-grained water ice, seen elsewhere on the surface within outcrops and fracture walls. Here the "blue" ice is on a flat surface, indicating that the region is young enough not to have been coated by fine-grained water ice from the E ring. Results from the visual and infrared spectrometer (VIMS) instrument suggest that the green-colored material surrounding the tiger stripes is chemically distinct from the rest of the surface of Enceladus. VIMS detected crystalline water ice in the stripes, suggesting that they are quite young (likely less than 1,000 years old) or the surface ice has been thermally altered in the recent past. VIMS also detected simple organic (carbon-containing) compounds in the tiger stripes, chemistry not found anywhere else on Enceladus thus far. And in 27 June 2018, scientists reported the detection of complex macromolecular organics on Enceladus' jet plumes, as sampled by the Cassini orbiter.One of these areas of "blue" ice in the south polar region was observed at high resolution during the July 14, 2005 flyby, revealing an area of extreme tectonic deformation and blocky terrain, with some areas covered in boulders 10–100 m across. | What year were pictures taken of Enceladus's south pole? | 7461836a40e86d7302118fbf546a9c55f8d6f4fe | en | 2005 |
The discoveries Cassini made at Enceladus have prompted studies into follow-up mission concepts, including a probe flyby (Journey to Enceladus and Titan or JET) to analyze plume contents in-situ, a lander by the German Aerospace Center to study the habitability potential of its subsurface ocean (Enceladus Explorer), and two astrobiology-oriented mission concepts (the Enceladus Life Finder and Life Investigation For Enceladus (LIFE)).The European Space Agency (ESA) was assessing concepts in 2008 to send a probe to Enceladus in a mission to be combined with studies of Titan: Titan Saturn System Mission (TSSM). TSSM was a joint NASA/ESA flagship-class proposal for exploration of Saturn's moons, with a focus on Enceladus, and it was competing against the Europa Jupiter System Mission (EJSM) proposal for funding. In February 2009, it was announced that NASA/ESA had given the EJSM mission priority ahead of TSSM, although TSSM will continue to be studied and evaluated. | Which mission was considered more important by NASA? | 11ce5ad7b966892f28efb848eb742d37d0c408c2 | en | the EJSM mission |
Voyager 2 was the first spacecraft to observe Enceladus's surface in detail, in August 1981. Examination of the resulting highest-resolution imagery revealed at least five different types of terrain, including several regions of cratered terrain, regions of smooth (young) terrain, and lanes of ridged terrain often bordering the smooth areas. In addition, extensive linear cracks and scarps were observed. Given the relative lack of craters on the smooth plains, these regions are probably less than a few hundred million years old. Accordingly, Enceladus must have been recently active with "water volcanism" or other processes that renew the surface. The fresh, clean ice that dominates its surface gives Enceladus the most reflective surface of any body in the Solar System, with a visual geometric albedo of 1.38 and bolometric Bond albedo of 0.81±0.04. Because it reflects so much sunlight, its surface only reaches a mean noon temperature of −198 °C (−324 °F), somewhat colder than other Saturnian satellites.Observations during three flybys by Cassini on February 17, March 9, and July 14, 2005, revealed Enceladus' surface features in much greater detail than the Voyager 2 observations. The smooth plains, which Voyager 2 had observed, resolved into relatively crater-free regions filled with numerous small ridges and scarps. Numerous fractures were found within the older, cratered terrain, suggesting that the surface has been subjected to extensive deformation since the craters were formed. Some areas contain no craters, indicating major resurfacing events in the geologically recent past. There are fissures, plains, corrugated terrain and other crustal deformations. Several additional regions of young terrain were discovered in areas not well-imaged by either Voyager spacecraft, such as the bizarre terrain near the south pole. All of this indicates that Enceladus's interior may be liquid today, even though it should have been frozen long ago. | Where were the young terrain discovered? | 2b86cc8838dd2f17d69afbb493ca7e98b62508e1 | en | near the south pole |
As intriguing as geometric Newtonian gravity may be, its basis, classical mechanics, is merely a limiting case of (special) relativistic mechanics. In the language of symmetry: where gravity can be neglected, physics is Lorentz invariant as in special relativity rather than Galilei invariant as in classical mechanics. (The defining symmetry of special relativity is the Poincaré group, which includes translations, rotations and boosts.) The differences between the two become significant when dealing with speeds approaching the speed of light, and with high-energy phenomena.With Lorentz symmetry, additional structures come into play. They are defined by the set of light cones (see image). The light-cones define a causal structure: for each event A, there is a set of events that can, in principle, either influence or be influenced by A via signals or interactions that do not need to travel faster than light (such as event B in the image), and a set of events for which such an influence is impossible (such as event C in the image). These sets are observer-independent. In conjunction with the world-lines of freely falling particles, the light-cones can be used to reconstruct the space–time's semi-Riemannian metric, at least up to a positive scalar factor. In mathematical terms, this defines a conformal structure or conformal geometry. | In Symmetry, what is the special relativity of movements? | 232b14bebdf00ba29173731437d47a4278d7c3b3 | en | Poincaré group |
At the base of classical mechanics is the notion that a body's motion can be described as a combination of free (or inertial) motion, and deviations from this free motion. Such deviations are caused by external forces acting on a body in accordance with Newton's second law of motion, which states that the net force acting on a body is equal to that body's (inertial) mass multiplied by its acceleration. The preferred inertial motions are related to the geometry of space and time: in the standard reference frames of classical mechanics, objects in free motion move along straight lines at constant speed. In modern parlance, their paths are geodesics, straight world lines in curved spacetime.Conversely, one might expect that inertial motions, once identified by observing the actual motions of bodies and making allowances for the external forces (such as electromagnetism or friction), can be used to define the geometry of space, as well as a time coordinate. However, there is an ambiguity once gravity comes into play. According to Newton's law of gravity, and independently verified by experiments such as that of Eötvös and its successors (see Eötvös experiment), there is a universality of free fall (also known as the weak equivalence principle, or the universal equality of inertial and passive-gravitational mass): the trajectory of a test body in free fall depends only on its position and initial speed, but not on any of its material properties. A simplified version of this is embodied in Einstein's elevator experiment, illustrated in the figure on the right: for an observer in a small enclosed room, it is impossible to decide, by mapping the trajectory of bodies such as a dropped ball, whether the room is at rest in a gravitational field, or in free space aboard a rocket that is accelerating at a rate equal to that of the gravitational field.Given the universality of free fall, there is no observable distinction between inertial motion and motion under the influence of the gravitational force. This suggests the definition of a new class of inertial motion, namely that of objects in free fall under the influence of gravity. This new class of preferred motions, too, defines a geometry of space and time—in mathematical terms, it is the geodesic motion associated with a specific connection which depends on the gradient of the gravitational potential. Space, in this construction, still has the ordinary Euclidean geometry. However, spacetime as a whole is more complicated. As can be shown using simple thought experiments following the free-fall trajectories of different test particles, the result of transporting spacetime vectors that can denote a particle's velocity (time-like vectors) will vary with the particle's trajectory; mathematically speaking, the Newtonian connection is not integrable. From this, one can deduce that spacetime is curved. The resulting Newton–Cartan theory is a geometric formulation of Newtonian gravity using only covariant concepts, i.e. a description which is valid in any desired coordinate system. In this geometric description, tidal effects—the relative acceleration of bodies in free fall—are related to the derivative of the connection, showing how the modified geometry is caused by the presence of mass. | what makes objest free fall? | 444aff2e573454101fc25d8c80ea5d026526a03c | en | gravity |
General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics. General relativity generalizes special relativity and supersedes Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations. | What kind of theory is general relativity? | 0c5e36939a4f7b9b649cb24384386e66045e51d5 | en | geometric theory |
In general relativity, no material body can catch up with or overtake a light pulse. No influence from an event A can reach any other location X before light sent out at A to X. In consequence, an exploration of all light worldlines (null geodesics) yields key information about the spacetime's causal structure. This structure can be displayed using Penrose–Carter diagrams in which infinitely large regions of space and infinite time intervals are shrunk ("compactified") so as to fit onto a finite map, while light still travels along diagonals as in standard spacetime diagrams.Aware of the importance of causal structure, Roger Penrose and others developed what is known as global geometry. In global geometry, the object of study is not one particular solution (or family of solutions) to Einstein's equations. Rather, relations that hold true for all geodesics, such as the Raychaudhuri equation, and additional non-specific assumptions about the nature of matter (usually in the form of energy conditions) are used to derive general results. | A light must be sent out from where to where? | c0743cc7ff039fd531ce7e2198c85df06323759b | en | A to X |
Several relativistic effects are directly related to the relativity of direction. One is geodetic precession: the axis direction of a gyroscope in free fall in curved spacetime will change when compared, for instance, with the direction of light received from distant stars—even though such a gyroscope represents the way of keeping a direction as stable as possible ("parallel transport"). For the Moon–Earth system, this effect has been measured with the help of lunar laser ranging. More recently, it has been measured for test masses aboard the satellite Gravity Probe B to a precision of better than 0.3%.Near a rotating mass, there are gravitomagnetic or frame-dragging effects. A distant observer will determine that objects close to the mass get "dragged around". This is most extreme for rotating black holes where, for any object entering a zone known as the ergosphere, rotation is inevitable. Such effects can again be tested through their influence on the orientation of gyroscopes in free fall. Somewhat controversial tests have been performed using the LAGEOS satellites, confirming the relativistic prediction. Also the Mars Global Surveyor probe around Mars has been used. | What has assisted in measuring the geodetic precession of the Moon-Earth system? | 15ec3998ad199d71e8d0f622bdbd65764ebb14ff | en | lunar laser ranging |
Some predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light. Examples of such differences include gravitational time dilation, gravitational lensing, the gravitational redshift of light, and the gravitational time delay. The predictions of general relativity in relation to classical physics have been confirmed in all observations and experiments to date. Although general relativity is not the only relativistic theory of gravity, it is the simplest theory that is consistent with experimental data. However, unanswered questions remain, the most fundamental being how general relativity can be reconciled with the laws of quantum physics to produce a complete and self-consistent theory of quantum gravity. | Certain predictions of Einstein's theory of general relativity do not fall in line with what type of physics? | 9786f25f64439691c89c81c9744b4f30b416b4e2 | en | classical physics |
Soon after publishing the special theory of relativity in 1905, Einstein started thinking about how to incorporate gravity into his new relativistic framework. In 1907, beginning with a simple thought experiment involving an observer in free fall, he embarked on what would be an eight-year search for a relativistic theory of gravity. After numerous detours and false starts, his work culminated in the presentation to the Prussian Academy of Science in November 1915 of what are now known as the Einstein field equations. These equations specify how the geometry of space and time is influenced by whatever matter and radiation are present, and form the core of Einstein's general theory of relativity.The Einstein field equations are nonlinear and very difficult to solve. Einstein used approximation methods in working out initial predictions of the theory. But as early as 1916, the astrophysicist Karl Schwarzschild found the first non-trivial exact solution to the Einstein field equations, the Schwarzschild metric. This solution laid the groundwork for the description of the final stages of gravitational collapse, and the objects known today as black holes. In the same year, the first steps towards generalizing Schwarzschild's solution to electrically charged objects were taken, which eventually resulted in the Reissner–Nordström solution, now associated with electrically charged black holes. In 1917, Einstein applied his theory to the universe as a whole, initiating the field of relativistic cosmology. In line with contemporary thinking, he assumed a static universe, adding a new parameter to his original field equations—the cosmological constant—to match that observational presumption. By 1929, however, the work of Hubble and others had shown that our universe is expanding. This is readily described by the expanding cosmological solutions found by Friedmann in 1922, which do not require a cosmological constant. Lemaître used these solutions to formulate the earliest version of the Big Bang models, in which our universe has evolved from an extremely hot and dense earlier state. Einstein later declared the cosmological constant the biggest blunder of his life.During that period, general relativity remained something of a curiosity among physical theories. It was clearly superior to Newtonian gravity, being consistent with special relativity and accounting for several effects unexplained by the Newtonian theory. Einstein himself had shown in 1915 how his theory explained the anomalous perihelion advance of the planet Mercury without any arbitrary parameters ("fudge factors"). Similarly, a 1919 expedition led by Eddington confirmed general relativity's prediction for the deflection of starlight by the Sun during the total solar eclipse of May 29, 1919, making Einstein instantly famous. Yet the theory entered the mainstream of theoretical physics and astrophysics only with the developments between approximately 1960 and 1975, now known as the golden age of general relativity. Physicists began to understand the concept of a black hole, and to identify quasars as one of these objects' astrophysical manifestations. Ever more precise solar system tests confirmed the theory's predictive power, and relativistic cosmology, too, became amenable to direct observational tests.Over the years, general relativity has acquired a reputation as a theory of extraordinary beauty. Subrahmanyan Chandrasekhar has noted that at multiple levels, general relativity exhibits what Francis Bacon has termed, a "strangeness in the proportion" (i.e. elements that excite wonderment and surprise). It juxtaposes fundamental concepts (space and time versus matter and motion) which had previously been considered as entirely independent. Chandrasekhar also noted that Einstein's only guides in his search for an exact theory were the principle of equivalence and his sense that a proper description of gravity should be geometrical at its basis, so that there was an "element of revelation" in the manner in which Einstein arrived at his theory. Other elements of beauty associated with the general theory of relativity are its simplicity, symmetry, the manner in which it incorporates invariance and unification, and its perfect logical consistency. | What year did Eddington lead the expedition? | 4790bc4bd5a8c87fef240065d066adac42a73cb9 | en | 1919 |
The notion of evolution equations is intimately tied in with another aspect of general relativistic physics. In Einstein's theory, it turns out to be impossible to find a general definition for a seemingly simple property such as a system's total mass (or energy). The main reason is that the gravitational field—like any physical field—must be ascribed a certain energy, but that it proves to be fundamentally impossible to localize that energy.Nevertheless, there are possibilities to define a system's total mass, either using a hypothetical "infinitely distant observer" (ADM mass) or suitable symmetries (Komar mass). If one excludes from the system's total mass the energy being carried away to infinity by gravitational waves, the result is the Bondi mass at null infinity. Just as in classical physics, it can be shown that these masses are positive. Corresponding global definitions exist for momentum and angular momentum. There have also been a number of attempts to define quasi-local quantities, such as the mass of an isolated system formulated using only quantities defined within a finite region of space containing that system. The hope is to obtain a quantity useful for general statements about isolated systems, such as a more precise formulation of the hoop conjecture. | What is one definition of quasi-local quantities? | 6c0a01e73d4bc3620f2382f091657b9ecf793025 | en | the mass of an isolated system formulated using only quantities defined within a finite region of space containing that system |
is the spacetime metric. Isotropic and homogeneous solutions of these enhanced equations, the Friedmann–Lemaître–Robertson–Walker solutions, allow physicists to model a universe that has evolved over the past 14 billion years from a hot, early Big Bang phase. Once a small number of parameters (for example the universe's mean matter density) have been fixed by astronomical observation, further observational data can be used to put the models to the test. Predictions, all successful, include the initial abundance of chemical elements formed in a period of primordial nucleosynthesis, the large-scale structure of the universe, and the existence and properties of a "thermal echo" from the early cosmos, the cosmic background radiation.Astronomical observations of the cosmological expansion rate allow the total amount of matter in the universe to be estimated, although the nature of that matter remains mysterious in part. About 90% of all matter appears to be dark matter, which has mass (or, equivalently, gravitational influence), but does not interact electromagnetically and, hence, cannot be observed directly. There is no generally accepted description of this new kind of matter, within the framework of known particle physics or otherwise. Observational evidence from redshift surveys of distant supernovae and measurements of the cosmic background radiation also show that the evolution of our universe is significantly influenced by a cosmological constant resulting in an acceleration of cosmic expansion or, equivalently, by a form of energy with an unusual equation of state, known as dark energy, the nature of which remains unclear.An inflationary phase, an additional phase of strongly accelerated expansion at cosmic times of around 10−33 seconds, was hypothesized in 1980 to account for several puzzling observations that were unexplained by classical cosmological models, such as the nearly perfect homogeneity of the cosmic background radiation. Recent measurements of the cosmic background radiation have resulted in the first evidence for this scenario. However, there is a bewildering variety of possible inflationary scenarios, which cannot be restricted by current observations. An even larger question is the physics of the earliest universe, prior to the inflationary phase and close to where the classical models predict the big bang singularity. An authoritative answer would require a complete theory of quantum gravity, which has not yet been developed (cf. the section on quantum gravity, below). | What kind of gravity needs an authoritative answer? | 4d70d4c6366a3ee0993c0bae033733244f84f47a | en | quantum gravity |
The Constitution of Romania is based on the Constitution of France's Fifth Republic and was approved in a national referendum on 8 December 1991, and amended in October 2003 to bring it into conformity with the EU legislation. The country is governed on the basis of a multi-party democratic system and the separation of powers between the legislative, executive and judicial branches. It is a semi-presidential republic where executive functions are held by both government and the president. The latter is elected by popular vote for a maximum of two terms of five years and appoints the prime minister, who in turn appoints the Council of Ministers. The legislative branch of the government, collectively known as the Parliament (residing at the Palace of the Parliament), consists of two chambers (Senate and Chamber of Deputies) whose members are elected every four years by simple plurality.The justice system is independent of the other branches of government, and is made up of a hierarchical system of courts culminating in the High Court of Cassation and Justice, which is the supreme court of Romania. There are also courts of appeal, county courts and local courts. The Romanian judicial system is strongly influenced by the French model, considering that it is based on civil law and is inquisitorial in nature. The Constitutional Court (Curtea Constituțională) is responsible for judging the compliance of laws and other state regulations to the constitution, which is the fundamental law of the country and can only be amended through a public referendum. The 2007 entry into the EU has been a significant influence on its domestic policy, and including judicial reforms, increased judicial cooperation with other member states, and measures to combat corruption. | By which system is the Romanian judicial system is mostly isfluenced? | 20b8de16e8a657c1ff896646aad1725094916b44 | en | French model, |
Kyrgyz is a Turkic language of the Kipchak branch, closely related to Kazakh, Karakalpak, and Nogay Tatar. It was written in the Arabic alphabet until the twentieth century. Latin script was introduced and adopted in 1928, and was subsequently replaced on Stalin's orders by Cyrillic script in 1941. | In which language was the Kyrgyz alphabet written before? | d6732b84ccc296fd04e20e4ac4a2a00817294b74 | en | Arabic |
Many business and political affairs are carried out in Russian. Until recently, Kyrgyz remained a language spoken at home and was rarely used during meetings or other events. However, most parliamentary meetings today are conducted in Kyrgyz, with simultaneous interpretation available for those not speaking Kyrgyz. | Interpretation is provided for what language? | e3ef1715e6a22099d2a795d2ff2fb68212552391 | en | Kyrgyz |
Since independence, the sovereign state has officially been a unitary parliamentary republic, although it continues to endure ethnic conflicts, revolts, economic troubles, transitional governments and political conflict. Kyrgyzstan is a member of the Commonwealth of Independent States, the Eurasian Economic Union, the Collective Security Treaty Organization, the Shanghai Cooperation Organisation, the Organisation of Islamic Cooperation, the Turkic Council, the Türksoy community and the United Nations. | What is the name fo the Islamic organisation that Kyrgyzstan is a part of? | 0cd6543a6ccac9874930fd2cf7e1b40ac0afcce8 | en | the Organisation of Islamic Cooperation |
The climate varies regionally. The low-lying Fergana Valley in the southwest is subtropical and extremely hot in summer, with temperatures reaching 40 °C (104 °F) The northern foothills are temperate and the Tian Shan varies from dry continental to polar climate, depending on elevation. In the coldest areas temperatures are sub-zero for around 40 days in winter, and even some desert areas experience constant snowfall in this period. In the lowlands the temperature ranges from around -−6 °C (21 °F) in January to 24 °C (75 °F) in July. | How many days in winter are below zero? | 4c5d3e150b460d8b01cab7fc43d8343b6d2df1be | en | 40 |
Transport in Kyrgyzstan is severely constrained by the country's alpine topography. Roads have to snake up steep valleys, cross passes of 3,000 metres (9,800 ft) altitude and more, and are subject to frequent mudslides and snow avalanches. Winter travel is close to impossible in many of the more remote and high-altitude regions. | What are roads in Kyrgyzstan subject to? | 4628ba458563172cfbb0233f1a293d415dcbb938 | en | frequent mudslides and snow avalanches |
