What is the unit of measurement for magnetic force?

title: Magnetic field
text: The term 'magnetic field' is used for two distinct but closely related fields denoted by the symbols B and H. In the International System of Units, H is measured in units of amperes per meter and B is measured in teslas, which are equivalent to newtons per meter per ampere. H and B differ in how they account for magnetization. In a vacuum, B and H are the same aside from units; but in a magnetized material, B/ μ 0 {\displaystyle \mu _{0}} and H differ by the magnetization M of the material at that point in the material.
How large is the water rail?

title: Water rail
text: The water rail (Rallus aquaticus) is a bird of the rail family which breeds in well-vegetated wetlands across Europe, Asia and North Africa. Northern and eastern populations are migratory, but this species is a permanent resident in the warmer parts of its breeding range. The adult is 23–28cm (9–11in) long, and, like other rails, has a body that is flattened laterally, allowing it easier passage through the reed beds it inhabits. It has mainly brown upperparts and blue-grey underparts, black barring on the flanks, long toes, a short tail and a long reddish bill. Immature birds are generally similar in appearance to the adults, but the blue-grey in the plumage is replaced by buff. The downy chicks are black, as with all rails. The former subspecies R.indicus, has distinctive markings and a call that is very different from the pig-like squeal of the western races, and is now usually split as a separate species, the brown-cheeked rail.
When was the Washington Monument in Washington D.C. built?

title: Washington Monument
text: Construction of the monument began in 1848, and was halted from 1854 to 1877 due to a lack of funds, a struggle for control over the Washington National Monument Society, and the intervention of the American Civil War. Although the stone structure was completed in 1884, internal ironwork, the knoll, and other finishing touches were not completed until 1888. A difference in shading of the marble, visible approximately 150 feet (46m) or 27% up, shows where construction was halted and later resumed with marble from a different source. The original design was by Robert Mills, but he did not include his proposed colonnade due to a lack of funds, proceeding only with a bare obelisk. The cornerstone was laid on July 4, 1848; the first stone was laid atop the unfinished stump on August 7, 1880; the capstone was set on December 6, 1884; the completed monument was dedicated on February 21, 1885;[14] and officially opened October 9, 1888.
When was Confucius born?

title: Confucius
text: It is thought that Confucius was born on September 28, 551BC,[2][8] in the district of Zou (鄒邑) near present-day Qufu, China.[8][9] The area was notionally controlled by the kings of Zhou but effectively independent under the local lords of Lu. His father Kong He (or Shuliang He) was an elderly commandant of the local Lu garrison.[10] His ancestry traced back through the dukes of Song to the Shang dynasty which had preceded the Zhou.[11][12][13][14] Traditional accounts of Confucius's life relate that Kong He's grandfather had migrated the family from Song to Lu.[15]
What was the first synthetic polymer?

title: Polymer science
text: The first modern example of polymer science is Henri Braconnot's work in the 1830s. Henri, along with Christian Schönbein and others, developed derivatives of the natural polymer cellulose, producing new, semi-synthetic materials, such as celluloid and cellulose acetate. The term "polymer" was coined in 1833 by Jöns Jakob Berzelius, though Berzelius did little that would be considered polymer science in the modern sense. In the 1840s, Friedrich Ludersdorf and Nathaniel Hayward independently discovered that adding sulfur to raw natural rubber (polyisoprene) helped prevent the material from becoming sticky. In 1844 Charles Goodyear received a U.S. patent for vulcanizing natural rubber with sulfur and heat. Thomas Hancock had received a patent for the same process in the UK the year before. This process strengthened natural rubber and prevented it from melting with heat without losing flexibility. This made practical products such as waterproofed articles possible. It also facilitated practical manufacture of such rubberized materials. Vulcanized rubber represents the first commercially successful product of polymer research. In 1884 Hilaire de Chardonnet started the first artificial fiber plant based on regenerated cellulose, or viscose rayon, as a substitute for silk, but it was very flammable.[1] In 1907 Leo Baekeland invented the first synthetic plastic, a thermosetting phenol–formaldehyde resin called Bakelite.[2]
When did nation states start existing in Europe?

title: Nation state
text: The origins and early history of nation states are disputed. A major theoretical question is: "Which came first, the nation or the nation state?" Scholars such as Steven Weber, David Woodward, and Jeremy Black[9][10][11] have advanced the hypothesis that the nation state did not arise out of political ingenuity or an unknown undetermined source, nor was it an accident of history or political invention; but is an inadvertent byproduct of 15th-century intellectual discoveries in political economy, capitalism, mercantilism, political geography, and geography[12][13] combined together with cartography[14][15] and advances in map-making technologies.[16][17] It was with these intellectual discoveries and technological advances that the nation state arose. For others, the nation existed first, then nationalist movements arose for sovereignty, and the nation state was created to meet that demand. Some "modernization theories" of nationalism see it as a product of government policies to unify and modernize an already existing state. Most theories see the nation state as a 19th-century European phenomenon, facilitated by developments such as state-mandated education, mass literacy and mass media. However, historians also note the early emergence of a relatively unified state and identity in Portugal and the Dutch Republic.
How common are basal cancerous cells?

title: Basal-cell carcinoma
text: Basal-cell cancer is a very common skin cancer. It is much more common in fair-skinned individuals with a family history of basal-cell cancer and increases in incidence closer to the equator or at higher altitude. There are approximately 800,000[55] new cases yearly in the United States alone. Up to 30% of Caucasians develop basal-cell carcinomas in their lifetime.[56] In Canada, the most common skin cancer is basal-cell carcinoma (as much as one third of all cancer diagnoses), affecting 1 in 7 individuals over a lifetime.[57]

When did women gain the right to vote in England?

title: Women's suffrage in the United Kingdom
text: Finally in 1918, Parliament passed an act granting the vote to women over the age of 30 who were householders, the wives of householders, occupiers of property with an annual rent of £5, and graduates of British universities. About 8.4 million women gained the vote.[22] In November 1918, the Parliament (Qualification of Women) Act 1918 was passed, allowing women to be elected into the House of Commons.[22] By 1928 the consensus was that votes for women had been successful. With the Conservative Party in full control in 1928, it passed the Representation of the People (Equal Franchise) Act that extended the voting franchise to all women over the age of 21, granting women the vote on the same terms as men,[23][24] although one Conservative opponent of the bill warned that it risked splitting the party for years to come.[25]
What is the origin of the name of the Danube River?

title: Danube
text: The river was known to the ancient Greeks as the Istros (Ἴστρος) a borrowing from a Daco-Thracian name meaning "strong, swift" (akin to Sanskrit iṣiras "swift"). In Latin, the Danube was variously known as Danubius, Danuvius or as Ister. [3] The Thraco-Phrygian name was Matoas,[4] "the bringer of luck".[5]
What was Gene Hackman's first film?

title: Gene Hackman
text: Hackman got various bit roles, for example on the TV series Route 66 in 1963, and began performing in several Off-Broadway plays. In 1964 he had an offer to co-star in the play Any Wednesday with actress Sandy Dennis. This opened the door to film work. His first role was in Lilith, with Warren Beatty in the leading role. In 1967 he appeared in an episode of the television series The Invaders entitled The Spores. Another supporting role, Buck Barrow in 1967's Bonnie and Clyde,[13] earned him an Academy Award nomination as Best Supporting Actor. In 1968 he appeared in an episode of I Spy, in the role of "Hunter", in the episode "Happy Birthday... Everybody". In 1968 he starred in the CBS Playhouse episode "My Father and My Mother" and the dystopian television film Shadow on the Land.[20] In 1969 he played a ski coach in Downhill Racer and an astronaut in Marooned. Also that year, he played a member of a barnstorming skydiving team that entertained mostly at county fairs, a movie which also inspired many to pursue skydiving and has a cult-like status amongst skydivers as a result: The Gypsy Moths. He nearly accepted the role of Mike Brady for the TV series, The Brady Bunch,[21] but was advised by his agent to decline in exchange for a more promising role, which he did.

Why does milk need to be pasteurized?

title: Pasteurization
text: Pasteurization or pasteurisation is a process in which certain packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat, usually less than 100°C (212°F), to eliminate pathogens and extend shelf life. The process is intended to sterilize foods by destroying or inactivating organisms that contribute to spoilage, including vegetative bacteria but not bacterial spores.[1][2]
Who was Saint Pardarn?

title: Padarn
text: Padarn (Latin: Paternus, Padarnus) (? – c. 550 AD)[1] was an early 6th century sanctified British Christian abbot-bishop who founded St Padarn's Church in[2] Ceredigion, Wales. The first bishop of Braga and Saint Paternus of Avranches in Normandy appear to be the same person. Padarn built a monastery in Vannes and is considered one of the seven founding saints of Brittany. Padarn's early vita is one of five insular and two Breton saints' lives that mention King Arthur independently of Geoffrey of Monmouth's Historia Regum Britanniae.[3]

Who won the case of Vallejos and Domingo v. Commissioner of Registration?

title: Vallejos v Commissioner of Registration
text: On 30 September 2011, Justice Johnson Lam of the Court of First Instance of the High Court (CFI) ruled in Vallejos' case that existing legislation restricting FDHs from qualifying for permanent residence contravened the Hong Kong Basic Law. Lam also found that Vallejos and Domingo, but not the three other applicants, had fulfilled the condition of taking Hong Kong as their only permanent home and being ordinarily resident in Hong Kong for seven years. The Court of Appeal of the High Court overturned the CFI's decision on Vallejos' case on 28 March 2012. Vallejos and Domingo then jointly appealed to the Court of Final Appeal (CFA), which heard their case on 26–28 February 2013; the CFA rejected their appeal on 25 March 2013.

When did Benjamin Franklin supposedly perform his kite experiment?

title: Kite experiment
text: Franklin's kite experiment was performed in Philadelphia in June 1752, according to the account by Priestley.[5] Franklin described the experiment in the Pennsylvania Gazette in October 19, 1752,[6][7] without mentioning that he himself had performed it.[8] This account was read to the Royal Society on December 21 and printed as such in the Philosophical Transactions.[5] A more complete account of Franklin's experiment was given by Joseph Priestley in 1767, who presumably learned the details directly from Franklin, who was in London at the time Priestley wrote the book.[5]
What is lanthanum named for?

title: Lanthanum
text: Lanthanum usually occurs together with cerium and the other rare earth elements. Lanthanum was first found by the Swedish chemist Carl Gustav Mosander in 1839 as an impurity in cerium nitrate – hence the name lanthanum, from the Ancient Greek λανθάνειν (lanthanein), meaning "to lie hidden". Although it is classified as a rare earth element, lanthanum is the 28th most abundant element in the Earth's crust, almost three times as abundant as lead. In minerals such as monazite and bastnäsite, lanthanum composes about a quarter of the lanthanide content.[5] It is extracted from those minerals by a process of such complexity that pure lanthanum metal was not isolated until 1923.
Who directed the first Harry Potter film?

title: Harry Potter (film series)
text: After Chris Columbus had finished working on Harry Potter and the Philosopher's Stone, he was hired to direct the second film, Harry Potter and the Chamber of Secrets. The production started within a week after the release of the first film. Columbus was set to direct all entries in the series,[35] but he did not want to return for the third film, Harry Potter and the Prisoner of Azkaban, claiming he was "burned out".[36] He moved to the position of producer, while Alfonso Cuarón was approached for the role of director. He was initially nervous about directing the instalment since he had not read any of the books or seen the films. After reading the series, he changed his mind and signed on to direct since he had immediately connected to the story.[37]
When was the Mona Lisa painted?

title: Mona Lisa
text: Leonardo da Vinci is thought by some to have begun painting the Mona Lisa in 1503 or 1504 in Florence, Italy.[27] Although the Louvre states that it was "doubtless painted between 1503 and 1506",[10] the art historian Martin Kemp says there are some difficulties in confirming the actual dates with certainty.[17] In addition, many Leonardo experts, such as Carlo Pedretti [4] and Alessandro Vezzosi,[5] are of the opinion that the painting is characteristic of Leonardo's style in the final years of his life, post-1513. Other academics argue that, given the historical documentation, Leonardo would have painted the work from 1513.[7] According to Leonardo's contemporary, Giorgio Vasari, "after he had lingered over it four years, [he] left it unfinished".[12] Leonardo, later in his life, is said to have regretted "never having completed a single work".[28]
Can an American hold a British title?

title: Title of Nobility Clause
text: The Title of Nobility Clause is a provision in Article I, Section 9, Clause 8 of the United States Constitution,[1] that prohibits the federal government from granting titles of nobility, and restricts members of the government from receiving gifts, emoluments, offices or titles from foreign states and monarchies without the consent of the United States Congress. Also known as the Emoluments Clause, it was designed to shield the republican character of the United States against so-called "corrupting foreign influences." This shield is reinforced by the corresponding prohibition on state titles of nobility in Article I, Section 10, and more generally by the Republican Guarantee Clause in Article IV, Section 4.[2]
When did János Kádár die?

His 32-year term as General Secretary covered most of the period the People's Republic of Hungary existed. Due to Kádár's age, declining health and declining political mastery, he retired as General Secretary of the party in 1988 and a younger generation consisting mostly of reformers took over.
When was Jacques-Louis David born?

title: Jacques-Louis David
text: Jacques-Louis David (French:[ʒaklwi david]; 30 August 1748 – 29 December 1825) was a French painter in the Neoclassical style, considered to be the preeminent painter of the era. In the 1780s his cerebral brand of history painting marked a change in taste away from Rococo frivolity toward classical austerity and severity and heightened feeling,[1] harmonizing with the moral climate of the final years of the Ancien Régime.
When did the Vikings arrive in Ireland?

title: History of Ireland (800–1169)
text: The first recorded Viking raid in Irish history occurred in AD 795 when Vikings, possibly from Norway[10] looted the island of Lambay.[note 4] This was followed by a raid on the coast of Brega in 798, and raids on the coast of Connacht in 807.[11] These early Viking raids were generally small in scale and quick.
Where was Tristan und Isolde first performed?

title: Tristan und Isolde
text: Tristan und Isolde (Tristan and Isolde, or Tristan and Isolda, or Tristran and Ysolt) is an opera, or music drama, in three acts by Richard Wagner to a German libretto by the composer, based largely on the 12th-century romance Tristan by Gottfried von Strassburg. It was composed between 1857 and 1859 and premiered at the Königliches Hof- und Nationaltheater in Munich on 10June 1865 with Hans von Bülow conducting. Wagner referred to the work not as an opera, but called it "eine Handlung" (literally a drama, a plot or an action), which was the equivalent of the term used by the Spanish playwright Calderón for his dramas.
When were the Acts of the Apostles written?

title: Acts of the Apostles
text: Acts and the Gospel of Luke make up a two-part work, Luke–Acts, by the same anonymous author, usually dated to around 80–90 AD.[2][3] The first part, the Gospel of Luke, tells how God fulfilled his plan for the world's salvation through the life, death, and resurrection of Jesus of Nazareth, the promised Messiah. Acts continues the story of Christianity in the 1st century, beginning with Jesus's ascension to Heaven. The early chapters, set in Jerusalem, describe the Day of Pentecost (the coming of the Holy Spirit) and the growth of the church in Jerusalem. Initially, the Jews are receptive to the Christian message, but soon they turn against the followers of Jesus. Rejected by the Jews, under the guidance of the Apostle Peter the message is taken to the Gentiles. The later chapters tell of Paul's conversion, his mission in Asia Minor and the Aegean, and finally his imprisonment in Rome, where, as the book ends, he awaits trial.
