The thermionic triode, a vacuum tube invented in 1907, enabled amplified radio technology and long-distance telephony. The triode, however, was a fragile device that consumed a lot of power. Physicist Julius Edgar Lilienfeld filed a patent for a field-effect transistor (FET) in Canada in 1925, which was intended to be a solid-state replacement for the triode. Lilienfeld also filed identical patents in the United States in 1926 and 1928. However, Lilienfeld did not publish any research articles about his devices nor did his patents cite any specific examples of a working prototype. Because the production of high-quality semiconductor materials was still decades away, Lilienfeld's solid-state amplifier ideas would not have found practical use in the 1920s and 1930s, even if such a device had been built. In 1934, German inventor Oskar Heil patented a similar device.

Question: What year did Lilienfeld file his patent?
Answer: 1925.

Waitz was influential among the British ethnologists. In 1863 the explorer Richard Francis Burton and the speech therapist James Hunt broke away from the Ethnological Society of London to form the Anthropological Society of London, which henceforward would follow the path of the new anthropology rather than just ethnology. It was the 2nd society dedicated to general anthropology in existence. Representatives from the French Société were present, though not Broca. In his keynote address, printed in the first volume of its new publication, The Anthropological Review, Hunt stressed the work of Waitz, adopting his definitions as a standard.[n 5] Among the first associates were the young Edward Burnett Tylor, inventor of cultural anthropology, and his brother Alfred Tylor, a geologist. Previously Edward had referred to himself as an ethnologist; subsequently, an anthropologist.

The consuls of the Roman Republic were the highest ranking ordinary magistrates; each consul served for one year. Consuls had supreme power in both civil and military matters. While in the city of Rome, the consuls were the head of the Roman government. They would preside over the senate and the assemblies. While abroad, each consul would command an army. His authority abroad would be nearly absolute. Praetors administered civil law and commanded provincial armies. Every five years, two censors were elected for an 18-month term, during which they would conduct a census. During the census, they could enroll citizens in the senate, or purge them from the senate. Aediles were officers elected to conduct domestic affairs in Rome, such as managing public games and shows. The quaestors would usually assist the consuls in Rome, and the governors in the provinces. Their duties were often financial.

The Recommended Exposure Index (REI) technique, new in the 2006 version of the standard, allows the manufacturer to specify a camera model’s EI choices arbitrarily. The choices are based solely on the manufacturer’s opinion of what EI values produce well-exposed sRGB images at the various sensor sensitivity settings. This is the only technique available under the standard for output formats that are not in the sRGB color space. This is also the only technique available under the standard when multi-zone metering (also called pattern metering) is used.

The Houston–The Woodlands–Sugar Land MSA's gross domestic product (GDP) in 2012 was $489 billion, making it the fourth-largest of any metropolitan area in the United States and larger than Austria's, Venezuela's, or South Africa's GDP. Only 26 countries other than the United States have a gross domestic product exceeding Houston's regional gross area product (GAP). In 2010, mining (which consists almost entirely of exploration and production of oil and gas in Houston) accounted for 26.3% of Houston's GAP up sharply in response to high energy prices and a decreased worldwide surplus of oil production capacity, followed by engineering services, health services, and manufacturing.

The phase of reflection of electromagnetic waves depends on the polarization of the incident wave. Given the larger refractive index of the ground (typically n=2) compared to air (n=1), the phase of horizontally polarized radiation is reversed upon reflection (a phase shift of  radians or 180°). On the other hand, the vertical component of the wave's electric field is reflected at grazing angles of incidence approximately in phase. These phase shifts apply as well to a ground modelled as a good electrical conductor.

Question: Besides a ground, what has these phases apply well to?
Answer: electrical conductor.

According to Max Clifford: Read All About It, written by Clifford and Angela Levin, La Salle invented the story out of frustration with Starr who had been working on a book with McCaffrey. She contacted an acquaintance who worked for The Sun in Manchester. The story reportedly delighted MacKenzie, who was keen to run it, and Max Clifford, who had been Starr's public relations agent. Starr had to be persuaded that the apparent revelation would not damage him; the attention helped to revive his career. In his 2001 autobiography Unwrapped, Starr wrote that the incident was a complete fabrication: "I have never eaten or even nibbled a live hamster, gerbil, guinea pig, mouse, shrew, vole or any other small mammal."

Comics are a medium used to express ideas by images, often combined with text or other visual information. Comics frequently takes the form of juxtaposed sequences of panels of images. Often textual devices such as speech balloons, captions, and onomatopoeia indicate dialogue, narration, sound effects, or other information. Size and arrangement of panels contribute to narrative pacing. Cartooning and similar forms of illustration are the most common image-making means in comics; fumetti is a form which uses photographic images. Common forms of comics include comic strips, editorial and gag cartoons, and comic books. Since the late 20th century, bound volumes such as graphic novels, comics albums, and tankōbon have become increasingly common, and online webcomics have proliferated in the 21st century.

The word ale comes from Old English ealu (plural ealoþ), in turn from Proto-Germanic *alu (plural *aluþ), ultimately from the Proto-Indo-European base *h₂elut-, which holds connotations of "sorcery, magic, possession, intoxication". The word beer comes from Old English bēor, from Proto-Germanic *beuzą, probably from Proto-Indo-European *bʰeusóm, originally "brewer's yeast, beer dregs", although other theories have been provided connecting the word with Old English bēow, "barley", or Latin bibere, "to drink". On the currency of two words for the same thing in the Germanic languages, the 12th-century Old Icelandic poem Alvíssmál says, "Ale it is called among men, but among the gods, beer."

al-Qarawīyīn University in Fez, Morocco is recognised by many historians as the oldest degree-granting university in the world, having been founded in 859 by Fatima al-Fihri. While the madrasa college could also issue degrees at all levels, the jāmiʻahs (such as al-Qarawīyīn and al-Azhar University) differed in the sense that they were larger institutions, more universal in terms of their complete source of studies, had individual faculties for different subjects, and could house a number of mosques, madaris, and other institutions within them. Such an institution has thus been described as an "Islamic university".

John Lewis Newcastle (formerly Bainbridge) in Newcastle upon Tyne, is the world's oldest Department Store. It is still known to many of its customers as Bainbridge, despite the name change to 'John Lewis'. The Newcastle institution dates back to 1838 when Emerson Muschamp Bainbridge, aged 21, went into partnership with William Alder Dunn and opened a draper's and fashion in Market Street, Newcastle. In terms of retailing history, one of the most significant facts about the Newcastle Bainbridge shop, is that as early as 1849 weekly takings were recorded by department, making it the earliest of all department stores. This ledger survives and is kept in the John Lewis archives. John Lewis bought the Bainbridge store in 1952.

As the economy and the middle class expanded, there was an increasing number of amateur musicians. One manifestation of this involved women, who became more involved with music on a social level. Women were already engaged in professional roles as singers, and increased their presence in the amateur performers' scene, especially with keyboard music. Music publishers begin to print music that amateurs could understand and play. The majority of the works that were published were for keyboard, voice and keyboard, and chamber ensemble. After these initial genres were popularized, from the mid-century on, amateur groups sang choral music, which then became a new trend for publishers to capitalize on. The increasing study of the fine arts, as well as access to amateur-friendly published works, led to more people becoming interested in reading and discussing music. Music magazines, reviews, and critical works which suited amateurs as well as connoisseurs began to surface.

This influx was compounded by the decline of the Western Sudanic Mali Empire in 1375 and the Songhai Empire in 1591. Additionally, as inland regions underwent desertification, inhabitants moved to the wetter coast. These new inhabitants brought skills such as cotton spinning, cloth weaving, iron smelting, rice and sorghum cultivation, and social and political institutions from the Mali and Songhai empires. Shortly after the Mane conquered the region, the Vai people of the former Mali Empire immigrated into the Grand Cape Mount region. The ethnic Kru opposed the influx of Vai, forming an alliance with the Mane to stop further influx of Vai.[citation needed]

In the mid 1970s, various American groups (some with ties to Downtown Manhattan's punk scene, including Television and Suicide) had begun expanding on the vocabulary of punk music. Midwestern groups such as Pere Ubu and Devo drew inspiration from the region's derelict industrial environments, employing conceptual art techniques, musique concrète and unconventional verbal styles that would presage the post-punk movement by several years. A variety of subsequent groups, including New York-based Talking Heads and Boston-based Mission of Burma, combined elements of punk with art school sensibilities. In 1978, the former band began a series of collaborations with British ambient pioneer and ex-Roxy Music member Brian Eno, experimenting with Dada-influenced lyrical techniques, dance music, and African polyrhythms. San Francisco's vibrant post-punk scene was centered around such groups as Chrome, the Residents and Tuxedomoon, who incorporated multimedia experimentation, film and ideas from Antonin Artaud's Theater of Cruelty.

In 1922, Benito Mussolini's rise to power in Italy brought profound changes to the colonial government in Italian Eritrea. After il Duce declared the birth of the Italian Empire in May 1936, Italian Eritrea (enlarged with northern Ethiopia's regions) and Italian Somaliland were merged with the just conquered Ethiopia in the new Italian East Africa (Africa Orientale Italiana) administrative territory. This Fascist period was characterized by imperial expansion in the name of a "new Roman Empire". Eritrea was chosen by the Italian government to be the industrial center of Italian East Africa.

Muslims have been living in Tibet since as early as the 8th or 9th century. In Tibetan cities, there are small communities of Muslims, known as Kachee (Kache), who trace their origin to immigrants from three main regions: Kashmir (Kachee Yul in ancient Tibetan), Ladakh and the Central Asian Turkic countries. Islamic influence in Tibet also came from Persia. After 1959 a group of Tibetan Muslims made a case for Indian nationality based on their historic roots to Kashmir and the Indian government declared all Tibetan Muslims Indian citizens later on that year. Other Muslim ethnic groups who have long inhabited Tibet include Hui, Salar, Dongxiang and Bonan. There is also a well established Chinese Muslim community (gya kachee), which traces its ancestry back to the Hui ethnic group of China.

South West Africa became known as Namibia by the UN when the General Assembly changed the territory's name by Resolution 2372 (XXII) of 12 June 1968. In 1978 the UN Security Council passed UN Resolution 435 which planned a transition toward independence for Namibia. Attempts to persuade South Africa to agree to the plan's implementation were not successful until 1988 when the transition to independence finally started under a diplomatic agreement between South Africa, Angola and Cuba, with the USSR and the USA as observers, under which South Africa agreed to withdraw and demobilise its forces in Namibia. As a result, Cuba agreed to pull back its troops in southern Angola sent to support the MPLA in its war for control of Angola with UNITA.

By the 1840s, India was no longer capable of supplying the vast quantities of cotton fibers needed by mechanized British factories, while shipping bulky, low-price cotton from India to Britain was time-consuming and expensive. This, coupled with the emergence of American cotton as a superior type (due to the longer, stronger fibers of the two domesticated native American species, Gossypium hirsutum and Gossypium barbadense), encouraged British traders to purchase cotton from plantations in the United States and plantations in the Caribbean. By the mid-19th century, "King Cotton" had become the backbone of the southern American economy. In the United States, cultivating and harvesting cotton became the leading occupation of slaves.

Nanjing is the intersection of Yangtze River, an east-west water transport artery, and Nanjing–Beijing railway, a south-north land transport artery, hence the name “door of the east and west, throat of the south and north”. Furthermore, the west part of the Ningzhen range is in Nanjing; the Loong-like Zhong Mountain is curling in the east of the city; the tiger-like Stone Mountain is crouching in the west of the city, hence the name “the Zhong Mountain, a dragon curling, and the Stone Mountain, a tiger crouching”. Mr. Sun Yet-sen spoke highly of Nanjing in the “Constructive Scheme for Our Country”, “The position of Nanjing is wonderful since mountains, lakes and plains all integrated in it. It is hard to find another city like this.”

Von Neumann entered the Lutheran Fasori Evangelikus Gimnázium in 1911. This was one of the best schools in Budapest, part of a brilliant education system designed for the elite. Under the Hungarian system, children received all their education at the one gymnasium. Despite being run by the Lutheran Church, the majority of its pupils were Jewish. The school system produced a generation noted for intellectual achievement, that included Theodore von Kármán (b. 1881), George de Hevesy (b. 1885), Leó Szilárd (b. 1898), Eugene Wigner (b. 1902), Edward Teller (b. 1908), and Paul Erdős (b. 1913). Collectively, they were sometimes known as Martians. Wigner was a year ahead of von Neumann at the Lutheran School. When asked why the Hungary of his generation had produced so many geniuses, Wigner, who won the Nobel Prize in Physics in 1963, replied that von Neumann was the only genius.

In March 2001, 40 multi-national pharmaceutical companies brought litigation against South Africa for its Medicines Act, which allowed the generic production of antiretroviral drugs (ARVs) for treating HIV, despite the fact that these drugs were on-patent. HIV was and is an epidemic in South Africa, and ARVs at the time cost between 10,000 and 15,000 USD per patient per year. This was unaffordable for most South African citizens, and so the South African government committed to providing ARVs at prices closer to what people could afford. To do so, they would need to ignore the patents on drugs and produce generics within the country (using a compulsory license), or import them from abroad. After international protest in favour of public health rights (including the collection of 250,000 signatures by MSF), the governments of several developed countries (including The Netherlands, Germany, France, and later the US) backed the South African government, and the case was dropped in April of that year.

The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with about 350,000 species. Like gymnosperms, angiosperms are seed-producing plants; they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term "angiosperm" comes from the Greek composite word (angeion-, "case" or "casing", and sperma, "seed") meaning "enclosed seeds", after the enclosed condition of the seeds.
