Franklin's electrostatic machine

Franklin was not the first to build an electrostatic generator. European scientists developed machines to generate static electricity decades earlier. In 1663, Otto von Guericke generated static electricity with a device that used a sphere of sulfur.[1] Francis Hauksbee developed a more advanced electrostatic generator around 1704 using a glass bulb that had a vacuum. He later replaced the globe with a glass tube of about 2.5 feet (0.76m) emptied of air.[1] The glass tube was a less effective static generator than the globe, but it became more popular because it was easier to use.[2]

Question: When was the electrostatic machine invented?
Answer: 1663

Toy balloon

The first rubber balloons were made by Professor Michael Faraday in 1824 for use in his experiments with hydrogen at the Royal Institution in London. "The caoutchouc is exceedingly elastic", he wrote in the Quarterly Journal of Science the same year. "Bags made of it...have been expanded by having air forced into them, until the caoutchouc was quite transparent, and when expanded by hydrogen they were so light as to form balloons with considerable ascending power...." Faraday made his balloons by cutting round two sheets of rubber laid together and pressing the edges together. The tacky rubber welded automatically, and the inside of the balloon was rubbed with flour to prevent the opposing surfaces joining together.[8]

Question: Who made the first rubber balloon?
Answer: Professor Michael Faraday

Smilodon

Fossils of Smilodon were discovered in North America from the second half of the 19th century onwards.[1] In 1869, American paleontologist Joseph Leidy described a maxilla fragment with a molar, which had been discovered in a petroleum bed in Hardin County, Texas. He referred the specimen to the genus Felis (which was then used for most cats, extant as well as extinct) but found it distinct enough to be part of its own subgenus, as F. (Trucifelis) fatalis.[5] The species name means "fate" or "destiny", but it is thought Leidy intended it to mean "fatal".[6] In an 1880 article about extinct American cats, American paleontologist Edward Drinker Cope pointed out that the F.fatalis molar was identical to that of Smilodon, and he proposed the new combination S.fatalis.[7] Most North American finds were scanty until excavations began in the La Brea Tar Pits in Los Angeles, where hundreds of individuals of S.fatalis have been found since 1875.[1] S.fatalis has junior synonyms such as S.mercerii, S.floridanus, and S.californicus.[4] American paleontologist Annalisa Berta considered the holotype of S.fatalis too incomplete to be an adequate type specimen, and the species has at times been proposed to be a junior synonym of S.populator.[3] Swedish paleontologists Björn Kurtén and Lars Werdelin supported the distinctness of the two species in 1990.[8]

Question: When was the Smilodon discovered?
Answer: 19th century onwards
Tropical cyclone naming

Before the formal start of naming, tropical cyclones were named after places, objects, or saints' feast days on which they occurred. The credit for the first usage of personal names for weather systems is generally given to the Queensland Government Meteorologist Clement Wragge, who named systems between 1887 and 1907. This system of naming weather systems subsequently fell into disuse for several years after Wragge retired, until it was revived in the latter part of World War II for the Western Pacific. Formal naming schemes and naming lists have subsequently been introduced and developed for the Eastern, Central, Western and Southern Pacific basins, as well as the Australian region, Atlantic Ocean and Indian Ocean.

Question: When did the convention of hurricane naming begin?
Answer: between 1887 and 1907

Machine gun

The first practical self-powered machine gun was invented in 1884 by Sir Hiram Maxim. The Maxim machine gun used the recoil power of the previously fired bullet to reload rather than being hand-powered, enabling a much higher rate of fire than was possible using earlier designs such as the Nordenfelt and Gatling weapons. Maxim also introduced the use of water cooling, via a water jacket around the barrel, to reduce overheating. Maxim's gun was widely adopted, and derivative designs were used on all sides during the First World War. The design required fewer crew and was lighter and more usable than the Nordenfelt and Gatling guns. First World War combat experience demonstrated the military importance of the machine gun. The United States Army issued four machine guns per regiment in 1912, but that allowance increased to 336 machine guns per regiment by 1919.[22]

Question: Who invented the first machine gun?
Answer: Sir Hiram Maxim

Angkor Wat

Angkor Wat (/ˌæŋkɔːr ˈwɒt/; Khmer: អង្គរវត្ត, "Capital Temple") is a temple complex in Cambodia and one of the largest religious monuments in the world, on a site measuring 162.6 hectares (1,626,000m2; 402 acres).[1] Originally constructed as a Hindu temple dedicated to the god Vishnu for the Khmer Empire, it was gradually transformed into a Buddhist temple towards the end of the 12th century.[2] It was built by the Khmer King Suryavarman II[3] in the early 12th century in Yaśodharapura (Khmer: យសោធរបុរៈ, present-day Angkor), the capital of the Khmer Empire, as his state temple and eventual mausoleum. Breaking from the Shaiva tradition of previous kings, Angkor Wat was instead dedicated to Vishnu. As the best-preserved temple at the site, it is the only one to have remained a significant religious centre since its foundation. The temple is at the top of the high classical style of Khmer architecture. It has become a symbol of Cambodia,[4] appearing on its national flag, and it is the country's prime attraction for visitors.[5]

Standardized test

Standardized testing has been a part of American education since the 1800s, but the widespread reliance on standardized is largely a 20th-century phenomenon. For instance the College Entrance Examination Board did not begin standardized testing in connection to higher education until 1900. The College Entrance Examination Board was established and in 1901, the first examinations were administered around the country in nine subjects. This test was implemented with the idea of creating standardized admissions for the United States in northeastern elite universities. Originally, the test was also meant for top boarding school in order to standardize curriculum.[10] With origins in World War I the Army Alpha and Beta tests developed by Robert Yerkes and colleagues.[11] Before then, immigration in the mid-19th century contributed to the growth of standardized tests in the United States.[12] Standardized tests were used in immigration when people first came over to test social roles and find social power and status.[13]

Question: When were standardized tests introduced in American schools?
Answer: since the 1800s
University of Ottawa

The university's main campus is situated within the neighbourhood of Sandy Hill. The main campus is bordered to the north by the ByWard Market district, to the east by Sandy Hill's residential area, and to the southwest by Nicholas Street, which runs adjacent to the Rideau Canal on the western half of the University. As of the 2010-2011 academic year, the main campus occupied 35.3ha (87 acres), though the University owns and manages other properties throughout the city, raising the university's total extent to 42.5ha (105 acres).[28] The main campus moved two times before settling in its final location in 1856. When the institution was first founded, the campus was located next to the Notre-Dame Cathedral Basilica. With space a major issue in 1852, the campus moved to a location that is now across from the National Gallery of Canada. In 1856, the institution moved to its present location.[14]

Question: When was the University of Ottawa founded?
Answer: 1856
Factory

Richard Arkwright is the person credited with inventing the prototype of the modern factory. After he patented his water frame in 1769, he established Cromford Mill, in Derbyshire, England, significantly expanding the village of Cromford to accommodate the migrant workers new to the area. The factory system was a new way of organizing labour made necessary by the development of machines which were too large to house in a worker's cottage. Working hours were as long as they had been for the farmer, that is, from dawn to dusk, six days per week. Overall, this practice essentially reduced skilled and unskilled workers to replaceable commodities. Arkwright's factory was the first successful cotton spinning factory in the world; it showed unequivocally the way ahead for industry and was widely copied.

Question: Where was the first factory in the Industrial Revolution?
Answer: Derbyshire, England
