Orientalism, as theorized by Edward Said, refers to how the West developed an imaginative geography of the East. This imaginative geography relies on an essentializing discourse that represents neither the diversity nor the social reality of the East. Rather, by essentializing the East, this discourse uses the idea of place-based identities to create difference and distance between "we" the West and "them" the East, or "here" in the West and "there" in the East. This difference was particularly apparent in textual and visual works of early European studies of the Orient that positioned the East as irrational and backward in opposition to the rational and progressive West. Defining the East as a negative vision of itself, as its inferior, not only increased the West’s sense of self, but also was a way of ordering the East and making it known to the West so that it could be dominated and controlled. The discourse of Orientalism therefore served as an ideological justification of early Western imperialism, as it formed a body of knowledge and ideas that rationalized social, cultural, political, and economic control of other territories.

With 4:51 left in regulation, Carolina got the ball on their own 24-yard line with a chance to mount a game-winning drive, and soon faced 3rd-and-9. On the next play, Miller stripped the ball away from Newton, and after several players dove for it, it took a long bounce backwards and was recovered by Ward, who returned it five yards to the Panthers 4-yard line. Although several players dove into the pile to attempt to recover it, Newton did not and his lack of aggression later earned him heavy criticism. Meanwhile, Denver's offense was kept out of the end zone for three plays, but a holding penalty on cornerback Josh Norman gave the Broncos a new set of downs. Then Anderson scored on a 2-yard touchdown run and Manning completed a pass to Bennie Fowler for a 2-point conversion, giving Denver a 24–10 lead with 3:08 left and essentially putting the game away. Carolina had two more drives, but failed to get a first down on each one.

With a budget of $230,000, the surviving original lunar broadcast data from Apollo 11 was compiled by Nafzger and assigned to Lowry Digital for restoration. The video was processed to remove random noise and camera shake without destroying historical legitimacy. The images were from tapes in Australia, the CBS News archive, and kinescope recordings made at Johnson Space Center. The restored video, remaining in black and white, contains conservative digital enhancements and did not include sound quality improvements.

After an unmanned LM test flight AS-206, a crew would fly the first Block II CSM and LM in a dual mission known as AS-207/208, or AS-278 (each spacecraft would be launched on a separate Saturn IB.) The Block II crew positions were titled Commander (CDR) Command Module Pilot (CMP) and Lunar Module Pilot (LMP). The astronauts would begin wearing a new Apollo spacesuit, designed to accommodate lunar extravehicular activity (EVA). The traditional visor helmet was replaced with a clear "fishbowl" type for greater visibility, and the lunar surface EVA suit would include a water-cooled undergarment.

On October 6, 1973, Syria and Egypt, with support from other Arab nations, launched a surprise attack on Israel, on Yom Kippur. This renewal of hostilities in the Arab–Israeli conflict released the underlying economic pressure on oil prices. At the time, Iran was the world's second-largest oil exporter and a close US ally. Weeks later, the Shah of Iran said in an interview: "Of course [the price of oil] is going to rise... Certainly! And how!... You've [Western nations] increased the price of the wheat you sell us by 300 percent, and the same for sugar and cement... You buy our crude oil and sell it back to us, refined as petrochemicals, at a hundred times the price you've paid us... It's only fair that, from now on, you should pay more for oil. Let's say ten times more."

Some modern scholars, such as Fielding H. Garrison, are of the opinion that the origin of the science of geology can be traced to Persia after the Muslim conquests had come to an end. Abu al-Rayhan al-Biruni (973–1048 CE) was one of the earliest Persian geologists, whose works included the earliest writings on the geology of India, hypothesizing that the Indian subcontinent was once a sea. Drawing from Greek and Indian scientific literature that were not destroyed by the Muslim conquests, the Persian scholar Ibn Sina (Avicenna, 981–1037) proposed detailed explanations for the formation of mountains, the origin of earthquakes, and other topics central to modern geology, which provided an essential foundation for the later development of the science. In China, the polymath Shen Kuo (1031–1095) formulated a hypothesis for the process of land formation: based on his observation of fossil animal shells in a geological stratum in a mountain hundreds of miles from the ocean, he inferred that the land was formed by erosion of the mountains and by deposition of silt.

The principal Treaties that form the European Union began with common rules for coal and steel, and then atomic energy, but more complete and formal institutions were established through the Treaty of Rome 1957 and the Maastricht Treaty 1992 (now: TFEU). Minor amendments were made during the 1960s and 1970s. Major amending treaties were signed to complete the development of a single, internal market in the Single European Act 1986, to further the development of a more social Europe in the Treaty of Amsterdam 1997, and to make minor amendments to the relative power of member states in the EU institutions in the Treaty of Nice 2001 and the Treaty of Lisbon 2007. Since its establishment, more member states have joined through a series of accession treaties, from the UK, Ireland, Denmark and Norway in 1972 (though Norway did not end up joining), Greece in 1979, Spain and Portugal 1985, Austria, Finland, Norway and Sweden in 1994 (though again Norway failed to join, because of lack of support in the referendum), the Czech Republic, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia in 2004, Romania and Bulgaria in 2007 and Croatia in 2013. Greenland signed a Treaty in 1985 giving it a special status.

As Jamukha and Temüjin drifted apart in their friendship, each began consolidating power, and soon became rivals. Jamukha supported the traditional Mongolian aristocracy, while Temüjin followed a meritocratic method, and attracted a broader, though lower class, range of followers. Due to his earlier defeat of the Merkits, and a proclamation by the shaman Kokochu that the Eternal Blue Sky had set aside the world for Temüjin, Temüjin began rising to power. In 1186, Temüjin was elected khan of the Mongols. However, Jamukha, threatened by Temüjin's rapid ascent, quickly moved to stop Temüjin's ambitions. In 1187, he launched an attack against his former friend with an army of thirty thousand troops. Temüjin hastily gathered together his followers to defend against the attack, but he was decisively beaten in the Battle of Dalan Balzhut. Jamukha horrified people greatly and harmed his image by boiling seventy young male captives alive in cauldrons, alienating many of his potential followers and eliciting sympathy for Temüjin. Toghrul, as Temüjin's patron, was exiled to the Qara Khitai. The life of Temüjin for the next ten years is very unclear, as historical records are mostly silent on that period.

Non-revolutionary civil disobedience is a simple disobedience of laws on the grounds that they are judged "wrong" by an individual conscience, or as part of an effort to render certain laws ineffective, to cause their repeal, or to exert pressure to get one's political wishes on some other issue. Revolutionary civil disobedience is more of an active attempt to overthrow a government (or to change cultural traditions, social customs, religious beliefs, etc...revolution doesn't have to be political, i.e. "cultural revolution", it simply implies sweeping and widespread change to a section of the social fabric). Gandhi's acts have been described as revolutionary civil disobedience. It has been claimed that the Hungarians under Ferenc Deák directed revolutionary civil disobedience against the Austrian government. Thoreau also wrote of civil disobedience accomplishing "peaceable revolution." Howard Zinn, Harvey Wheeler, and others have identified the right espoused in The Declaration of Independence to "alter or abolish" an unjust government to be a principle of civil disobedience.

Despite their soft, gelatinous bodies, fossils thought to represent ctenophores, apparently with no tentacles but many more comb-rows than modern forms, have been found in lagerstätten as far back as the early Cambrian, about 515 million years ago. The position of the ctenophores in the evolutionary family tree of animals has long been debated, and the majority view at present, based on molecular phylogenetics, is that cnidarians and bilaterians are more closely related to each other than either is to ctenophores. A recent molecular phylogenetics analysis concluded that the common ancestor of all modern ctenophores was cydippid-like, and that all the modern groups appeared relatively recently, probably after the Cretaceous–Paleogene extinction event 66 million years ago. Evidence accumulating since the 1980s indicates that the "cydippids" are not monophyletic, in other words do not include all and only the descendants of a single common ancestor, because all the other traditional ctenophore groups are descendants of various cydippids.

The heat required for boiling the water and supplying the steam can be derived from various sources, most commonly from burning combustible materials with an appropriate supply of air in a closed space (called variously combustion chamber, firebox). In some cases the heat source is a nuclear reactor, geothermal energy, solar energy or waste heat from an internal combustion engine or industrial process. In the case of model or toy steam engines, the heat source can be an electric heating element.

In many parts of the United States, after the 1954 decision in the landmark court case Brown v. Board of Education of Topeka that demanded United States schools desegregate "with all deliberate speed", local families organized a wave of private "Christian academies". In much of the U.S. South, many white students migrated to the academies, while public schools became in turn more heavily concentrated with African-American students (see List of private schools in Mississippi). The academic content of the academies was usually College Preparatory. Since the 1970s, many of these "segregation academies" have shut down, although some continue to operate.[citation needed]

Much of the work of the Scottish Parliament is done in committee. The role of committees is stronger in the Scottish Parliament than in other parliamentary systems, partly as a means of strengthening the role of backbenchers in their scrutiny of the government and partly to compensate for the fact that there is no revising chamber. The principal role of committees in the Scottish Parliament is to take evidence from witnesses, conduct inquiries and scrutinise legislation. Committee meetings take place on Tuesday, Wednesday and Thursday morning when Parliament is sitting. Committees can also meet at other locations throughout Scotland.

Seamans' establishment of an ad-hoc committee headed by his special technical assistant Nicholas E. Golovin in July 1961, to recommend a launch vehicle to be used in the Apollo program, represented a turning point in NASA's mission mode decision. This committee recognized that the chosen mode was an important part of the launch vehicle choice, and recommended in favor of a hybrid EOR-LOR mode. Its consideration of LOR —as well as Houbolt's ceaseless work— played an important role in publicizing the workability of the approach. In late 1961 and early 1962, members of the Manned Spacecraft Center began to come around to support LOR, including the newly hired deputy director of the Office of Manned Space Flight, Joseph Shea, who became a champion of LOR. The engineers at Marshall Space Flight Center (MSFC) took longer to become convinced of its merits, but their conversion was announced by Wernher von Braun at a briefing in June 1962.

While the Commission has a monopoly on initiating legislation, the European Parliament and the Council of the European Union have powers of amendment and veto during the legislative process. According to the Treaty on European Union articles 9 and 10, the EU observes "the principle of equality of its citizens" and is meant to be founded on "representative democracy". In practice, equality and democracy are deficient because the elected representatives in the Parliament cannot initiate legislation against the Commission's wishes, citizens of smallest countries have ten times the voting weight in Parliament as citizens of the largest countries, and "qualified majorities" or consensus of the Council are required to legislate. The justification for this "democratic deficit" under the Treaties is usually thought to be that completion integration of the European economy and political institutions required the technical coordination of experts, while popular understanding of the EU developed and nationalist sentiments declined post-war. Over time, this has meant the Parliament gradually assumed more voice: from being an unelected assembly, to its first direct elections in 1979, to having increasingly more rights in the legislative process. Citizens' rights are therefore limited compared to the democratic polities within all European member states: under TEU article 11 citizens and associations have the rights such as publicising their views and submit an initiative that must be considered by the Commission with one million signatures. TFEU article 227 contains a further right for citizens to petition the Parliament on issues which affect them. Parliament elections, take place every five years, and votes for Members of the European Parliament in member states must be organised by proportional representation or a single transferable vote. There are 750 MEPs and their numbers are "degressively proportional" according to member state size. This means - although the Council is meant to be the body representing member states - in the Parliament citizens of smaller member states have more voice than citizens in larger member states. MEPs divide, as they do in national Parliaments, along political party lines: the conservative European People's Party is currently the largest, and the Party of European Socialists leads the opposition. Parties do not receive public funds from the EU, as the Court of Justice held in Parti écologiste "Les Verts" v Parliament that this was entirely an issue to be regulated by the member states. The Parliament's powers include calling inquiries into maladministration or appoint an Ombudsman pending any court proceedings. It can require the Commission respond to questions and by a two-thirds majority can censure the whole Commission (as happened to the Santer Commission in 1999). In some cases, the Parliament has explicit consultation rights, which the Commission must genuinely follow. However its role participation in the legislative process still remains limited because no member can actually or pass legislation without the Commission and Council, meaning power ("kratia") is not in the hands of directly elected representatives of the people ("demos"): in the EU it is not yet true that "the administration is in the hands of the many and not of the few."

In the early 1970s, ABC completed its transition to color; the decade as a whole would mark a turning point for ABC, as it began to pass CBS and NBC in the ratings to become the first place network. It also began to use behavioral and demographic data to better determine what types of sponsors to sell advertising slots to and provide programming that would appeal towards certain audiences. ABC's gains in audience share were greatly helped by the fact that several smaller markets had grown large enough to allow full-time affiliations from all three networks.

The Black Death ravaged much of the Islamic world. Plague was present in at least one location in the Islamic world virtually every year between 1500 and 1850. Plague repeatedly struck the cities of North Africa. Algiers lost 30 to 50 thousand inhabitants to it in 1620–21, and again in 1654–57, 1665, 1691, and 1740–42. Plague remained a major event in Ottoman society until the second quarter of the 19th century. Between 1701 and 1750, thirty-seven larger and smaller epidemics were recorded in Constantinople, and an additional thirty-one between 1751 and 1800. Baghdad has suffered severely from visitations of the plague, and sometimes two-thirds of its population has been wiped out.

Between Bingen and Bonn, the Middle Rhine flows through the Rhine Gorge, a formation which was created by erosion. The rate of erosion equaled the uplift in the region, such that the river was left at about its original level while the surrounding lands raised. The gorge is quite deep and is the stretch of the river which is known for its many castles and vineyards. It is a UNESCO World Heritage Site (2002) and known as "the Romantic Rhine", with more than 40 castles and fortresses from the Middle Ages and many quaint and lovely country villages.

Medical knowledge had stagnated during the Middle Ages. The most authoritative account at the time came from the medical faculty in Paris in a report to the king of France that blamed the heavens, in the form of a conjunction of three planets in 1345 that caused a "great pestilence in the air". This report became the first and most widely circulated of a series of plague tracts that sought to give advice to sufferers. That the plague was caused by bad air became the most widely accepted theory. Today, this is known as the Miasma theory. The word 'plague' had no special significance at this time, and only the recurrence of outbreaks during the Middle Ages gave it the name that has become the medical term.

Sometimes the prosecution proposes a plea bargain to civil disobedients, as in the case of the Camden 28, in which the defendants were offered an opportunity to plead guilty to one misdemeanor count and receive no jail time. In some mass arrest situations, the activists decide to use solidarity tactics to secure the same plea bargain for everyone. But some activists have opted to enter a blind plea, pleading guilty without any plea agreement in place. Mohandas Gandhi pleaded guilty and told the court, "I am here to . . . submit cheerfully to the highest penalty that can be inflicted upon me for what in law is a deliberate crime and what appears to me to be the highest duty of a citizen."

Lindisfarne are a folk-rock group with a strong Tyneside connection. Their most famous song, "Fog on the Tyne" (1971), was covered by Geordie ex-footballer Paul Gascoigne in 1990. Venom, reckoned by many to be the originators of black metal and extremely influential to the extreme metal scene as a whole, formed in Newcastle in 1979. Folk metal band Skyclad, often regarded as the first folk metal band, also formed in Newcastle after the break-up of Martin Walkyier thrash metal band, Sabbat. Andy Taylor, former lead guitarist of Duran Duran was born here in 1961. Brian Johnson was a member of local rock band Geordie before becoming the lead vocalist of AC/DC.

The study also found that there were two previously unknown but related clades (genetic branches) of the Y. pestis genome associated with medieval mass graves. These clades (which are thought to be extinct) were found to be ancestral to modern isolates of the modern Y. pestis strains Y. p. orientalis and Y. p. medievalis, suggesting the plague may have entered Europe in two waves. Surveys of plague pit remains in France and England indicate the first variant entered Europe through the port of Marseille around November 1347 and spread through France over the next two years, eventually reaching England in the spring of 1349, where it spread through the country in three epidemics. Surveys of plague pit remains from the Dutch town of Bergen op Zoom showed the Y. pestis genotype responsible for the pandemic that spread through the Low Countries from 1350 differed from that found in Britain and France, implying Bergen op Zoom (and possibly other parts of the southern Netherlands) was not directly infected from England or France in 1349 and suggesting a second wave of plague, different from those in Britain and France, may have been carried to the Low Countries from Norway, the Hanseatic cities or another site.

Disorders of the immune system can result in autoimmune diseases, inflammatory diseases and cancer. Immunodeficiency occurs when the immune system is less active than normal, resulting in recurring and life-threatening infections. In humans, immunodeficiency can either be the result of a genetic disease such as severe combined immunodeficiency, acquired conditions such as HIV/AIDS, or the use of immunosuppressive medication. In contrast, autoimmunity results from a hyperactive immune system attacking normal tissues as if they were foreign organisms. Common autoimmune diseases include Hashimoto's thyroiditis, rheumatoid arthritis, diabetes mellitus type 1, and systemic lupus erythematosus. Immunology covers the study of all aspects of the immune system.

Somewhere around a billion years ago, a free-living cyanobacterium entered an early eukaryotic cell, either as food or as an internal parasite, but managed to escape the phagocytic vacuole it was contained in. The two innermost lipid-bilayer membranes that surround all chloroplasts correspond to the outer and inner membranes of the ancestral cyanobacterium's gram negative cell wall, and not the phagosomal membrane from the host, which was probably lost. The new cellular resident quickly became an advantage, providing food for the eukaryotic host, which allowed it to live within it. Over time, the cyanobacterium was assimilated, and many of its genes were lost or transferred to the nucleus of the host. Some of its proteins were then synthesized in the cytoplasm of the host cell, and imported back into the chloroplast (formerly the cyanobacterium).

Other predecessors of the Reformed church included the pro-reform and Gallican Roman Catholics, such as Jacques Lefevre (c. 1455–1536). The Gallicans briefly achieved independence for the French church, on the principle that the religion of France could not be controlled by the Bishop of Rome, a foreign power. During the Protestant Reformation, Lefevre, a professor at the University of Paris, published his French translation of the New Testament in 1523, followed by the whole Bible in the French language in 1530. William Farel was a student of Lefevre who went on to become a leader of the Swiss Reformation, establishing a Protestant government in Geneva. Jean Cauvin (John Calvin), another student at the University of Paris, also converted to Protestantism. Long after the sect was suppressed by Francis I, the remaining French Waldensians, then mostly in the Luberon region, sought to join William Farel, Calvin and the Reformation, and Olivetan published a French Bible for them. The French Confession of 1559 shows a decidedly Calvinistic influence. Sometime between 1550 and 1580, members of the Reformed church in France came to be commonly known as Huguenots.[citation needed]

In 1939 Chinese Nationalist soldiers took the mausoleum from its position at the 'Lord's Enclosure' (Mongolian: Edsen Khoroo) in Mongolia to protect it from Japanese troops. It was taken through Communist-held territory in Yan'an some 900 km on carts to safety at a Buddhist monastery, the Dongshan Dafo Dian, where it remained for ten years. In 1949, as Communist troops advanced, the Nationalist soldiers moved it another 200 km farther west to the famous Tibetan monastery of Kumbum Monastery or Ta'er Shi near Xining, which soon fell under Communist control. In early 1954, Genghis Khan's bier and relics were returned to the Lord's Enclosure in Mongolia. By 1956 a new temple was erected there to house them. In 1968 during the Cultural Revolution, Red Guards destroyed almost everything of value. The "relics" were remade in the 1970s and a great marble statue of Genghis was completed in 1989.

Grissom, White, and Chaffee decided to name their flight Apollo 1 as a motivational focus on the first manned flight. They trained and conducted tests of their spacecraft at North American, and in the altitude chamber at the Kennedy Space Center. A "plugs-out" test was planned for January, which would simulate a launch countdown on LC-34 with the spacecraft transferring from pad-supplied to internal power. If successful, this would be followed by a more rigorous countdown simulation test closer to the February 21 launch, with both spacecraft and launch vehicle fueled.

The Rhine-Meuse Delta, the most important natural region of the Netherlands begins near Millingen aan de Rijn, close to the Dutch-German border with the division of the Rhine into Waal and Nederrijn. Since the Rhine contributes most of the water, the shorter term Rhine Delta is commonly used. However, this name is also used for the river delta where the Rhine flows into Lake Constance, so it is clearer to call the larger one Rhine-Meuse delta, or even Rhine–Meuse–Scheldt delta, as the Scheldt ends in the same delta.

The principal Treaties that form the European Union began with common rules for coal and steel, and then atomic energy, but more complete and formal institutions were established through the Treaty of Rome 1957 and the Maastricht Treaty 1992 (now: TFEU). Minor amendments were made during the 1960s and 1970s. Major amending treaties were signed to complete the development of a single, internal market in the Single European Act 1986, to further the development of a more social Europe in the Treaty of Amsterdam 1997, and to make minor amendments to the relative power of member states in the EU institutions in the Treaty of Nice 2001 and the Treaty of Lisbon 2007. Since its establishment, more member states have joined through a series of accession treaties, from the UK, Ireland, Denmark and Norway in 1972 (though Norway did not end up joining), Greece in 1979, Spain and Portugal 1985, Austria, Finland, Norway and Sweden in 1994 (though again Norway failed to join, because of lack of support in the referendum), the Czech Republic, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia in 2004, Romania and Bulgaria in 2007 and Croatia in 2013.

These chloroplasts, which can be traced back directly to a cyanobacterial ancestor, are known as primary plastids ("plastid" in this context means almost the same thing as chloroplast). All primary chloroplasts belong to one of three chloroplast lineages—the glaucophyte chloroplast lineage, the rhodophyte, or red algal chloroplast lineage, or the chloroplastidan, or green chloroplast lineage. The second two are the largest, and the green chloroplast lineage is the one that contains the land plants.

Some modern scholars, such as Fielding H. Garrison, are of the opinion that the origin of the science of geology can be traced to Persia after the Muslim conquests had come to an end. Abu al-Rayhan al-Biruni (973–1048 CE) was one of the earliest Persian geologists, whose works included the earliest writings on the geology of India, hypothesizing that the Indian subcontinent was once a sea. Drawing from Greek and Indian scientific literature that were not destroyed by the Muslim conquests, the Persian scholar Ibn Sina (Avicenna, 981–1037) proposed detailed explanations for the formation of mountains, the origin of earthquakes, and other topics central to modern geology, which provided an essential foundation for the later development of the science. In China, the polymath Shen Kuo (1031–1095) formulated a hypothesis for the process of land formation: based on his observation of fossil animal shells in a geological stratum in a mountain hundreds of miles from the ocean, he inferred that the land was formed by erosion of the mountains and by deposition of silt.

With 4:51 left in regulation, Carolina got the ball on their own 24-yard line with a chance to mount a game-winning drive, and soon faced 3rd-and-9. On the next play, Miller stripped the ball away from Newton, and after several players dove for it, it took a long bounce backwards and was recovered by Ward, who returned it five yards to the Panthers 4-yard line. Although several players dove into the pile to attempt to recover it, Newton did not and his lack of aggression later earned him heavy criticism. Meanwhile, Denver's offense was kept out of the end zone for three plays, but a holding penalty on cornerback Josh Norman gave the Broncos a new set of downs. Then Anderson scored on a 2-yard touchdown run and Manning completed a pass to Bennie Fowler for a 2-point conversion, giving Denver a 24–10 lead with 3:08 left and essentially putting the game away. Carolina had two more drives, but failed to get a first down on each one.

Even before Washington returned, Dinwiddie had sent a company of 40 men under William Trent to that point, where in the early months of 1754 they began construction of a small stockaded fort. Governor Duquesne sent additional French forces under Claude-Pierre Pecaudy de Contrecœur to relieve Saint-Pierre during the same period, and Contrecœur led 500 men south from Fort Venango on April 5, 1754. When these forces arrived at the fort on April 16, Contrecœur generously allowed Trent's small company to withdraw. He purchased their construction tools to continue building what became Fort Duquesne.

The two most prominent Norman families to arrive in the Mediterranean were descendants of Tancred of Hauteville and the Drengot family, of whom Rainulf Drengot received the county of Aversa, the first Norman toehold in the south, from Duke Sergius IV of Naples in 1030. The Hauteville family achieved princely rank by proclaiming prince Guaimar IV of Salerno "Duke of Apulia and Calabria". He promptly awarded their elected leader, William Iron Arm, with the title of count in his capital of Melfi. The Drengot family thereafter attained the principality of Capua, and emperor Henry III legally ennobled the Hauteville leader, Drogo, as "dux et magister Italiae comesque Normannorum totius Apuliae et Calabriae" ("Duke and Master of Italy and Count of the Normans of all Apulia and Calabria") in 1047.

France took control of Algeria in 1830 but began in earnest to rebuild its worldwide empire after 1850, concentrating chiefly in North and West Africa, as well as South-East Asia, with other conquests in Central and East Africa, as well as the South Pacific. Republicans, at first hostile to empire, only became supportive when Germany started to build her own colonial empire. As it developed, the new empire took on roles of trade with France, supplying raw materials and purchasing manufactured items, as well as lending prestige to the motherland and spreading French civilization and language as well as Catholicism. It also provided crucial manpower in both World Wars.

"Seven Years" refers to events in Europe, from the official declaration of war in 1756 to the signing of the peace treaty in 1763. These dates do not correspond with the fighting on mainland North America, where the fighting between the two colonial powers was largely concluded in six years, from the Battle of Jumonville Glen in 1754 to the capture of Montreal in 1760.

The Grainger Market replaced an earlier market originally built in 1808 called the Butcher Market. The Grainger Market itself, was opened in 1835 and was Newcastle's first indoor market. At the time of its opening in 1835 it was said to be one of the largest and most beautiful markets in Europe. The opening was celebrated with a grand dinner attended by 2000 guests, and the Laing Art Gallery has a painting of this event. With the exception of the timber roof which was destroyed by a fire in 1901 and replaced by latticed-steel arches the Market is largely in its original condition. The Grainger Market architecture, like most in Grainger Town, which are either grade I or II listed, was listed grade I in 1954 by English Heritage.

While studying law and philosophy in England and Germany, Iqbal became a member of the London branch of the All India Muslim League. He came back to Lahore in 1908. While dividing his time between law practice and philosophical poetry, Iqbal had remained active in the Muslim League. He did not support Indian involvement in World War I and remained in close touch with Muslim political leaders such as Muhammad Ali Johar and Muhammad Ali Jinnah. He was a critic of the mainstream Indian nationalist and secularist Indian National Congress. Iqbal's seven English lectures were published by Oxford University press in 1934 in a book titled The Reconstruction of Religious Thought in Islam. These lectures dwell on the role of Islam as a religion as well as a political and legal philosophy in the modern age.

Economist Joseph Stiglitz presented evidence in 2009 that both global inequality and inequality within countries prevent growth by limiting aggregate demand. Economist Branko Milanovic, wrote in 2001 that, "The view that income inequality harms growth – or that improved equality can help sustain growth – has become more widely held in recent years. ... The main reason for this shift is the increasing importance of human capital in development. When physical capital mattered most, savings and investments were key. Then it was important to have a large contingent of rich people who could save a greater proportion of their income than the poor and invest it in physical capital. But now that human capital is scarcer than machines, widespread education has become the secret to growth."

James Hutton is often viewed as the first modern geologist. In 1785 he presented a paper entitled Theory of the Earth to the Royal Society of Edinburgh. In his paper, he explained his theory that the Earth must be much older than had previously been supposed in order to allow enough time for mountains to be eroded and for sediments to form new rocks at the bottom of the sea, which in turn were raised up to become dry land. Hutton published a two-volume version of his ideas in 1795 (Vol. 1, Vol. 2).

Endosymbiotic gene transfer is how we know about the lost chloroplasts in many chromalveolate lineages. Even if a chloroplast is eventually lost, the genes it donated to the former host's nucleus persist, providing evidence for the lost chloroplast's existence. For example, while diatoms (a heterokontophyte) now have a red algal derived chloroplast, the presence of many green algal genes in the diatom nucleus provide evidence that the diatom ancestor (probably the ancestor of all chromalveolates too) had a green algal derived chloroplast at some point, which was subsequently replaced by the red chloroplast.

The invasions of Baghdad, Samarkand, Urgench, Kiev, Vladimir among others caused mass murders, such as when portions of southern Khuzestan were completely destroyed. His descendant Hulagu Khan destroyed much of Iran's northern part and sacked Baghdad although his forces were halted by the Mamluks of Egypt, but Hulagu's descendant Ghazan Khan would return to beat the Egyptian Mamluks right out of Levant, Palestine and even Gaza. According to the works of the Persian historian Rashid-al-Din Hamadani, the Mongols killed more than 70,000 people in Merv and more than 190,000 in Nishapur. In 1237 Batu Khan, a grandson of Genghis Khan, launched an invasion into Kievan Rus'. Over the course of three years, the Mongols destroyed and annihilated all of the major cities of Eastern Europe with the exceptions of Novgorod and Pskov.

The Royal Geographical Society of London and other geographical societies in Europe had great influence and were able to fund travelers who would come back with tales of their discoveries. These societies also served as a space for travellers to share these stories.Political geographers such as Friedrich Ratzel of Germany and Halford Mackinder of Britain also supported imperialism. Ratzel believed expansion was necessary for a state’s survival while Mackinder supported Britain’s imperial expansion; these two arguments dominated the discipline for decades.

Oxygen was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774, but Priestley is often given priority because his work was published first. The name oxygen was coined in 1777 by Antoine Lavoisier, whose experiments with oxygen helped to discredit the then-popular phlogiston theory of combustion and corrosion. Its name derives from the Greek roots ὀξύς oxys, "acid", literally "sharp", referring to the sour taste of acids and -γενής -genes, "producer", literally "begetter", because at the time of naming, it was mistakenly thought that all acids required oxygen in their composition. Common uses of oxygen includes the production cycle of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, in oxygen therapy and life support systems in aircraft, submarines, spaceflight and diving.
