Some analysts believe that the blueprint of attack was reactivated soon after Pervez Musharraf was appointed in October 1998. After the war, Nawaz Sharif, Prime Minister of Pakistan during the Kargil conflict, claimed that he was unaware of the plans, and that he first learned about the situation when he received an urgent phone call from Atal Bihari Vajpayee, his counterpart in India. Sharif attributed the plan to Musharraf and "just two or three of his cronies", a view shared by some Pakistani writers who have stated that only four generals, including Musharraf, knew of the plan. Musharraf, however, asserted that Sharif had been briefed on the Kargil operation 15 days ahead of Vajpayee's journey to Lahore on 20 February.

He became a leading figure in and eventually the leader of the Awami League, founded in 1949 as an East Pakistan-based political party in Pakistan. Mujib is credited as an important figure in efforts to gain political autonomy for East Pakistan and later as the central figure behind the Bangladesh Liberation Movement and the Bangladesh Liberation War in 1971. Thus, he is regarded Jatir Janak or Jatir Pita ( or , both meaning "Father of the Nation") of Bangladesh.

The caliphate arose out of the death of Muhammad in 632 CE and the subsequent debate over the succession to his leadership. Abu Bakr, a close companion of Muhammad from the Banu Taym clan, was elected the first Rashidun leader and began the conquest of the Arabian Peninsula. He ruled from 632 to his death in 634. Abu Bakr was succeeded by Umar, his appointed successor from the Banu Adi clan, who began the conquest of Persia from 642 to 651, leading to the defeat of the Sassanid Empire. Umar was assassinated in 644 and was succeeded by Uthman, who was elected by a six-person committee arranged by Umar. Under Uthman began the conquest of Armenia, Fars and Khorasan. Uthman was assassinated in 656 and succeeded by Ali, who presided over the civil war known as the First Fitna (656–661). The war was primarily between those who supported Uthman's cousin and governor of the Levant, Muawiyah, and those who supported the caliph Ali. The civil war permanently consolidated the divide between Sunni and Shia Muslims, with Shia Muslims believing Ali to be the first rightful caliph and Imam after Muhammad. A third faction in the war supported the governor of Egypt, Amr ibn al-As. The war was decided in favour of the faction of Muawiyah, who established the Umayyad Caliphate in 661.

Sea surface temperature (SST) is the water temperature close to the ocean's surface. The exact meaning of "surface" varies according to the measurement method used, but it is between and below the sea surface. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass. Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth's oceans. Tropical cyclones can also cause a cool wake, due to turbulent mixing of the upper of the ocean. SST changes diurnally, like the air above it, but to a lesser degree. There is less SST variation on breezy days than on calm days. In addition, ocean currents such as the Atlantic Multidecadal Oscillation (AMO), can effect SST's on multi-decadal time scales, a major impact results from the global thermohaline circulation, which affects average SST significantly throughout most of the world's oceans.

The Bangladeshi Declaration of Independence was proclaimed from Chittagong by members of the Mukti Bahini – the national liberation army formed by Bengali military, paramilitary and civilians. The East Bengal Regiment and the East Pakistan Rifles played a crucial role in the resistance. Led by General M. A. G. Osmani and eleven sector commanders, the Bangladesh Forces waged a mass guerrilla war against the Pakistani military. They liberated numerous towns and cities in the initial months of the conflict. The Pakistan Army regained momentum in the monsoon. Bengali guerrillas carried out widespread sabotage, including Operation Jackpot against the Pakistan Navy. The nascent Bangladesh Air Force flew sorties against Pakistani military bases. By November, the Bangladesh forces restricted the Pakistani military to its barracks during the night. They secured control of most parts of the countryside.

The Russian Civil War (; 7 November 1917 – 25 October 1922) was a multi-party war in the former Russian Empire immediately after the two Russian Revolutions of 1917, as many factions vied to determine Russia's political future. The two largest combatant groups were the Red Army, fighting for the Bolshevik form of socialism led by Vladimir Lenin, and the loosely allied forces known as the White Army, which included diverse interests favoring political monarchism, economic capitalism and alternative forms of socialism, each with democratic and antidemocratic variants. In addition, rival militant socialists and nonideological Green armies fought against both the Bolsheviks and the Whites. Eight foreign nations intervened against the Red Army, notably the former Allied military forces from the World War and the pro-German armies. The Red Army eventually defeated the White Armed Forces of South Russia in Ukraine and the army led by Admiral Aleksandr Kolchak to the east in Siberia in 1919. The remains of the White forces commanded by Pyotr Nikolayevich Wrangel were beaten in Crimea and evacuated in late 1920. Lesser battles of the war continued on the periphery for two more years, and minor skirmishes with the remnants of the White forces in the Far East continued well into 1923. The war ended in 1923 in the sense that Bolshevik communist control of the newly formed Soviet Union was now assured, although armed national resistance in Central Asia was not completely crushed until 1934. There were an estimated 7,000,000–12,000,000 casualties during the war, mostly civilians. The Russian Civil War has been described by some as the greatest national catastrophe that Europe had yet seen.

Theory and observations suggest that very early in the history of the universe, there was an inflationary phase where the metric changed very rapidly, and that the remaining time-dependence of this metric is what we observe as the so-called Hubble expansion, the moving apart of all gravitationally unbound objects in the universe. The expanding universe is therefore a fundamental feature of the universe we inhabit — a universe fundamentally different from the static universe Albert Einstein first considered when he developed his gravitational theory.

The International Council of Women (ICW) was the first women's organization to work across national boundaries for the common cause of advocating human rights for women. In March and April 1888, women leaders came together in Washington D.C. with 80 speakers and 49 delegates representing 53 women's organizations from 9 countries: Canada, the United States, Ireland, India, England, Finland, Denmark, France and Norway. Women from professional organizations, trade unions, arts groups and benevolent societies participate. National Councils are affiliated to the ICW and thus make themselves heard at international level. In 1904, the ICW met in Berlin, Germany. The ICW worked with the League of Nations during the 1920s and the United Nations post-World War II. Today the ICW holds Consultative Status with the United Nations Economic and Social Council, the highest accreditation an NGO can achieve at the United Nations.

Ibrahim (, ), known as Abraham in the Hebrew Bible, is recognized as a prophet and messenger in Islam of God. Abraham plays a prominent role as an example of faith in Judaism, Christianity, and Islam. In Muslim belief, Abraham fulfilled all the commandments and trials wherein God nurtured him throughout his lifetime. As a result of his unwavering faith in God, Ibrahim was promised by God to be a leader to all the nations of the world. The Quran extols Ibrahim as a model, an exemplar, obedient and not an idolater. In this sense, Abraham has been described as representing "primordial man in universal surrender to the Divine Reality before its fragmentation into religions separated from each other by differences in form". The Islamic holy day Eid al-Adha is celebrated in memory of the sacrifice of Abraham, and each able bodied Muslim is supposed to perform the pilgrimage to pay homage at the Ka‘bah () in the Hijazi city of Mecca, which was built by Abraham and his son Ishmael as the first house of worship on earth.

Some view the birth of quantum chemistry as starting with the discovery of the Schrödinger equation and its application to the hydrogen atom in 1926. However, the 1927 article of Walter Heitler (1904-1981) and Fritz London, is often recognized as the first milestone in the history of quantum chemistry. This is the first application of quantum mechanics to the diatomic hydrogen molecule, and thus to the phenomenon of the chemical bond. In the following years much progress was accomplished by Edward Teller, Robert S. Mulliken, Max Born, J. Robert Oppenheimer, Linus Pauling, Erich Hückel, Douglas Hartree, Vladimir Fock, to cite a few. The history of quantum chemistry also goes through the 1838 discovery of cathode rays by Michael Faraday, the 1859 statement of the black body radiation problem by Gustav Kirchhoff, the 1877 suggestion by Ludwig Boltzmann that the energy states of a physical system could be discrete, and the 1900 quantum hypothesis by Max Planck that any energy radiating atomic system can theoretically be divided into a number of discrete energy elements "ε" such that each of these energy elements is proportional to the frequency "ν" with which they each individually radiate energy and a numerical value called Planck’s Constant. Then, in 1905, to explain the photoelectric effect (1839), i.e., that shining light on certain materials can function to eject electrons from the material, Albert Einstein postulated, based on Planck’s quantum hypothesis, that light itself consists of individual quantum particles, which later came to be called photons (1926). In the years to follow, this theoretical basis slowly began to be applied to chemical structure, reactivity, and bonding. Probably the greatest contribution to the field was made by Linus Pauling.

Anger becomes the predominant feeling behaviorally, cognitively, and physiologically when a person makes the conscious choice to take action to immediately stop the threatening behavior of another outside force.

The development of microprocessors made inexpensive computing available for the small business and hobbyist, which in turn led to the widespread use of interchangeable hardware components using a common interconnection (such as the S-100, SS-50, Apple II, ISA, and PCI buses), and an increasing need for "standard" operating systems to control them. The most important of the early OSes on these machines was Digital Research's CP/M-80 for the 8080 / 8085 / Z-80 CPUs. It was based on several Digital Equipment Corporation operating systems, mostly for the PDP-11 architecture. Microsoft's first operating system, MDOS/MIDAS, was designed along many of the PDP-11 features, but for microprocessor based systems. MS-DOS, or PC DOS when supplied by IBM, was based originally on CP/M-80. Each of these machines had a small boot program in ROM which loaded the OS itself from disk. The BIOS on the IBM-PC class machines was an extension of this idea and has accreted more features and functions in the 20 years since the first IBM-PC was introduced in 1981.

DNA was first isolated by Friedrich Miescher in 1869. Its molecular structure was first identified by Francis Crick and James Watson at the Cavendish Laboratory within the University of Cambridge in 1953, whose model-building efforts were guided by X-ray diffraction data acquired by Raymond Gosling, who was a post-graduate student of Rosalind Franklin. DNA is used by researchers as a molecular tool to explore physical laws and theories, such as the ergodic theorem and the theory of elasticity. The unique material properties of DNA have made it an attractive molecule for material scientists and engineers interested in micro- and nano-fabrication. Among notable advances in this field are DNA origami and DNA-based hybrid materials.

Its earliest fossil evidence dates to 1.8 million years ago (discovered 1991 in Dmanisi, Georgia). However, a 2017 analyses points to these specific fossils being more archaic, being related to H. naledi, which was considered one of the first homo species.

Recorded history or written history is a historical narrative based on a written record or other documented communication. It contrasts with other narratives of the past, such as mythological, oral or archeological traditions. For broader world history, recorded history begins with the accounts of the ancient world around the 4th millennium BC, and coincides with the invention of writing. For some geographic regions or cultures, written history is limited to a relatively recent period in human history because of the limited use of written records. Moreover, human cultures do not always record all of the information relevant to later historians, such as the full impact of natural disasters or the names of individuals; thus, recorded history for particular types of information is limited based on the types of records kept. Because of this, recorded history in different contexts may refer to different periods of time depending on the topic.

Norse mythology is primarily attested in dialects of Old Norse, a North Germanic language spoken by the Scandinavian people during the European Middle Ages, and the ancestor of modern Scandinavian languages. The majority of these Old Norse texts were created in Iceland, where the oral tradition stemming from the pre-Christian inhabitants of the island was collected and recorded in manuscripts. This occurred primarily in the 13th century. These texts include the "Prose Edda", composed in the 13th century by Snorri Sturluson, and the "Poetic Edda", a collection of poems from earlier traditional material anonymously compiled in the 13th century.

"Artemisia annua" extract, called "qinghao", was described vividly in the fourth-century Chinese physician Ge Hong's book "Zhouhou Beiji Fang" ("The Handbook of Prescriptions for Emergencies") as a treatment of malarial fever. Tu Youyou and her team were the first to investigate. In 1971 they found that their extract from the dried leaves (collected from Beijing) did not indicate any antimalarial activity. On careful reading of Ge Hong's description they changed their extraction method of using fresh leaves under low temperature. Ge Hong explicitly describes the recipe as: "qinghao, one bunch, take two sheng [2 × 0.2 l] of water for soaking it, wring it out, take the juice, ingest it in its entirety". They found that only the fresh plant specimen collected from Sichuan province would yield the active compound. They made the purified extract into tablets, which showed very low activity. They soon realized that the compound was very insoluble, and hence, made it in capsules. On 8 March 1972 they reported successful treatment of malaria in experimentally infected mice using the new extract. In August 1972 they reported a clinical trial in which 21 malarial patients were cured. In 1973 scientists at the Yunnan Institute of Materia Medica and Shandong Institute of Traditional Medicine and Materia Medica obtained the antimalarial compound in a crystalline form gave the name "huanghaosu" or "huanghuahaosu", which was eventually renamed "qinghaosu" (yet later to be popularised as "artemisinin", after the botanical name). (The chemical structure of artemisinin was worked out only in 1975, and published in 1977.) The same year Tu synthesized the compound dihydroartemisinin from the extract. This compound was more soluble and potent than the native compound. Other artemisinin derivatives were subsequently synthesized by other workers, of which the most important are artemether and artesunate. All clinical trials by this time confirmed that artemisinins are more effective than the conventional antimalarial drugs, such as chloroquine and quinine. They are now recognised not only as the most potent, but also as the safest and rapidly acting antimalarial drugs.

In 1956 Prime Minister S. W. R. D. Bandaranaike passed the "Sinhala Only Act", which replaced English with Sinhala as the only official language of the country. This was seen as a deliberate attempt to discourage the Sri Lankan Tamils from working in the Ceylon Civil Service and other public services. The Tamil-speaking minorities of Ceylon (Sri Lankan Tamils, Indian Tamils and Sri Lankan Moors) viewed the Act as linguistic, cultural and economic discrimination against them. Many Tamil-speaking civil servants/public servants were forced to resign because they weren't fluent in Sinhala. This was a prelude to the 1956 Gal Oya riots and the 1958 widespread riots in which thousands of Tamil civilians perished. The civil war was a direct result of the escalation of the confrontational politics that followed.

The Village () is a short novel by the Nobel Prize-winning Russian author Ivan Bunin, written in 1909 and first published in 1910 by the Saint Petersburg magazine "Sovremenny Mir" (issues Nos. 3, 10–11) under the title "Novelet" (). "The Village" caused much controversy at the time, though it was highly praised by Maxim Gorky (who from then on regarded the author as the major figure in Russian literature), among others, and is now generally regarded as Bunin's first masterpiece. Composed of brief episodes set in its author's birthplace at the time of the 1905 Revolution, it tells the story of two peasant brothers, one a brute drunk, the other a gentler, more sympathetic character. Bunin's realistic portrayal of the country life jarred with the idealized picture of "unspoiled" peasants which was common for the mainstream Russian literature, and featured the characters deemed 'offensive' by many, which were "so far below the average in terms of intelligence as to be scarcely human."

Captained by Naimur Rahman, Bangladesh lost by nine wickets, although "Wisden" noted that they "surpassed all expectations by matching their neighbours, and at times even enjoying the upper hand". Aminul Islam Bulbul scored 145 in the first innings, becoming the third person to have scored a century in their team's first Test; Rahman took six wickets for 132 runs, the second-best bowling figures in a country's maiden Test. In March 2001, former Australian Test cricketer Trevor Chappell was appointed coach. The following month Bangladesh embarked on a tour of Zimbabwe to play two Tests and three ODIs. Zimbabwe, who at the time were ranked ninth out of the ten Test teams, won all five matches. Bangladesh took part in the 2001–02 Asian Test Championship, the second and final time the championship was held and the first the team had been eligible to play in. They lost both their matches by an innings. Mohammad Ashraful made his debut in the series and became the youngest player to score a Test century in his first match. In November, Bangladesh hosted Zimbabwe for two Tests and three ODIs. The opening Test was curtailed by bad weather and ended in a draw; after losing their first five Tests, it was the first time Bangladesh had avoided defeat. Zimbabwe won all the remaining matches.

Chomsky befriended two linguists at the Massachusetts Institute of Technology (MIT), Morris Halle and Roman Jakobson, the latter of whom secured him an assistant professor position there in 1955. At MIT Chomsky spent half his time on a mechanical translation project and half teaching a course on linguistics and philosophy. He had been recruited to MIT by Jerome Wiesner, an influential scientist who was also involved in getting the US's nuclear missile program established Having brought such missile research to MIT, Wiesner then became a nuclear strategy adviser to both Presidents Eisenhower and Kennedy before returning to MIT to oversee research programmes at the Institute. Despite its military involvement, Chomsky has described MIT as "a pretty free and open place, open to experimentation and without rigid requirements. It was just perfect for someone of my idiosyncratic interests and work." In 1957 MIT promoted him to the position of associate professor, and from 1957 to 1958 he was also employed by Columbia University as a visiting professor. That same year, Chomsky's first child, a daughter named Aviva, was born, and he published his first book on linguistics, "Syntactic Structures", a work that radically opposed the dominant Harris–Bloomfield trend in the field. The response to Chomsky's ideas ranged from indifference to hostility, and his work proved divisive and caused "significant upheaval" in the discipline. Linguist John Lyons later asserted that it "revolutionized the scientific study of language". From 1958 to 1959 Chomsky was a National Science Foundation fellow at the Institute for Advanced Study in Princeton, New Jersey.

Jayasuriya's highest ODI score is 189 runs, scored against India in Sharjah in 2000. It remains the highest ODI score by a Sri Lankan, and at the time of the innings it was the third-highest in ODI history. Currently the score is 11th highest ODI score of all time and highest by a Sri Lankan. Jayasuriya was the previous record-holder for the fastest century (off 48 balls), before losing that to Shahid Afridi's 37 ball century. This is cited as the first ever fastest century scored in less than 50 balls in world cricket. The record was then broken by Corey Anderson of New Zealand (36 balls), which is currently held by AB de Villiers of South Africa with 31 ball century. He has also held the world record for most ODI sixes (270 in 441 ODIs), which was surpassed by Shahid Afridi during the 2010 Asia Cup match against Bangladesh. He became the fourth batsman to score more than 10,000 runs and the second batsman to score more than 12,000, and 13,000 runs in the history of ODIs. He also has 28 centuries, the fourth highest in ODIs. He held the record of scoring most runs in an ODI over (30; he has achieved this twice), and first batsman to score over 30 in an over. This record is now held by South Africa's Herschelle Gibbs (36 runs in an over).

The complex numbers give rise to the fundamental theorem of algebra: every non-constant polynomial equation with complex coefficients has a complex solution. This property is true of the complex numbers, but not the reals.

The treatise often makes references to the Bible and Aristotelian thought, and it is heavily influenced by the philosophical tenets of Neoplatonism. The first section of the book's main text is written using the scholastic methodology of Thomas Aquinas characterized by a mode of "disputed questions" most notably used in his "Summa Theologica". It was a standard mode of argumentation in scholastic discourse with a long tradition. Most of the citations in the "Malleus" come from multiple works of Aquinas, a highly influential author in theology. Aquinas is a main source for Section I but is cited in all sections; "Formicarius" by Johannes Nider is the important source for Section II, and "Directorium Inquisitorum" by Spanish inquisitor Nicholas Eymeric is a crucial source for Section III.

Pakistan has seen a rise in the values of dowries in recent decades, as in other South Asian countries. However, in Pakistan it is still expected that a bride will bring some kind of dowry with her to a marriage, whether she is Muslim, Hindu, or Christian. The Dower (bride price), called "mahr", and dowry, called "jahaiz", are both customs with long histories in Pakistan. Today, the dowry will often consist of jewelry, clothing, and money. Dowry is expected while the majority of marriages are consanguineously arranged between first cousins.

Mill's career as a colonial administrator at the British East India Company spanned from when he was 17 years old in 1823 until 1858, when the Company was abolished in favor of direct rule by the British crown over India. In 1836, he was promoted to the Company's Political Department, where he was responsible for correspondence pertaining to the Company's relations with the princely states, and in 1856, was finally promoted to the position of Examiner of Indian Correspondence. In "On Liberty", "A Few Words on Non-Intervention", and other works, Mill defended British imperialism by arguing that a fundamental distinction existed between civilized and barbarous peoples. Mill viewed countries such as India and China as having once been progressive, but that were now stagnant and barbarous, thus legitimizing British rule as benevolent despotism, "provided the end is [the barbarians'] improvement." When the crown proposed to take direct control over the colonies in India, he was tasked with defending Company rule, penning "Memorandum on the Improvements in the Administration of India during the Last Thirty Years" among other petitions. He was offered a seat on the Council of India, the body created to advise the new Secretary of State for India, but declined, citing his disapproval of the new system of rule.

The origins of this movement stem from the Chaucer and Spengler. The movement was officially launched however, in November 1961 from the residence of Malay Roy Choudhury and his brother Samir Roychoudhury in Patna. For this reason Malay Roy Choudhury is considered the creator of Hungryalist movement. Malay Roy Choudhury took the word "Hungry" from Geoffrey Chaucer's line "In Sowre Hungry Tyme" and they drew upon, among others, Oswald Spengler's histriographical ideas about the non-centrality of cultural evolution and organic progression, for philosophical inspiration. The movement was to last from 1961 to 1965. It is wrong to suggest that the movement was influenced by the Beat Generation, since Ginsberg did not visit Malay until April 1963, when he came to Patna. Poets Octavio Paz and Ernesto Cardenal were to visit Malay later during the 1960s. The hungry generation has some of the same ideals as The Papelipolas and the Barranquilla Group, both from Colombia, and the Spanish Generation of 68.

By the end of the month Asimov completed a second story, "Stowaway". Campbell rejected it on 22 July but—in "the nicest possible letter you could imagine"—encouraged him to continue writing, promising that Asimov might sell his work after another year and a dozen stories of practice. In October 1938, he sold the third story he finished, "Marooned Off Vesta", to "Amazing Stories", edited by Raymond A. Palmer, and it appeared in the March 1939 issue. Asimov was paid $64 (), or one cent a word. Two more stories appeared that year, "The Weapon Too Dreadful to Use" in the May "Amazing" and "Trends" in the July "Astounding", the issue fans later selected as the start of the Golden Age of Science Fiction. For 1940, ISFDB catalogs seven stories in four different pulp magazines, including one in "Astounding". His earnings became enough to pay for his education, but not yet enough for him to become a full-time writer.

Marx regarded history as having passed through several stages. The details of his periodisation vary somewhat through his works, but it essentially is: Primitive Communism – Slave societies – Feudalism – Capitalism – Socialism – Communism (capitalism being the present stage and communism the future). Marx occupied himself primarily with describing capitalism. Historians place the beginning of capitalism some time between about 1450 (Sombart) and some time in the 17th century (Hobsbawm).
