Melioidosis

Pathologist Alfred Whitmore and assistant Krishnaswami first reported the disease among beggars and morphine addicts at autopsy in Rangoon, present-day Myanmar, in a report published in 1912.[122] They distinguished it from glanders, a disease of humans and animals that is similar in presentation, but caused by a different micro-organism. B.pseudomallei, also known as the Whitmore bacillus, was identified in 1917 in Kuala Lumpur.[123] Arthur Conan Doyle may have read the 1912 report before writing a short story that involved the fictitious tropical disease "tapanuli fever" in a Sherlock Holmes adventure.[124]

Coronation of Elizabeth I

The coronation of Queen Elizabeth I as queen regnant of England and Ireland took place at Westminster Abbey, London, on 15 January 1559. Queen Elizabeth I had ascended the throne at the age of 25 upon the death of her half-sister, Queen Mary I, on 17 November 1558. Mary had reversed the Protestant Reformation which had been started by her two predecessors, so this was the last British coronation to be conducted under the authority of the Roman Catholic Church. Historians view Elizabeth's coronation as a statement of her intention restore England to Protestantism, but to allow the continuation of some Catholic customs, a compromise known as the Elizabethan Settlement.

Question: When was Elizabeth I crowned as Queen of England?
Answer: 15 January 1559

Black wildebeest

The black wildebeest or white-tailed gnu (Connochaetes gnou) is one of the two closely related wildebeest species. It is a member of the genus Connochaetes  and family Bovidae. It was first described in 1780 by Eberhard August Wilhelm von Zimmermann. The black wildebeest is typically 170–220cm (67–87in) in head-and-body length, and the typical weight is 110–180kg (240–400lb). Males stand about 111–121cm (44–48in) at the shoulder, while the height of the females is 106–116cm (42–46in). The black wildebeest is characterised by its white, long, horse-like tail. It also has a dark brown to black coat and long, dark-coloured hair between its forelegs and under its belly.

Georgia State Route 5

SR5 was established at least as early as 1919 from SR3 in Marietta to the Tennessee state line north-northwest of Blue Ridge. SR8 was established at this time on the path of SR5 from Douglasville to Austell.[2] By the end of 1926, US78 was designated on SR8 between Douglasville and Austell. The Pickens County portion of the Canton–Jasper segment of SR5 had a "completed hard surface". Two segments had a "completed semi hard surface": the Cherokee County portion of the Canton–Jasper segment and the southern half of the segment from Blue Ridge to the Tennessee state line. Two segments had a "sand clay or top soil": the Douglasville–Austell segment of US78/SR8 and the Cherokee County portion of the Marietta–Canton segment of SR5. Two segments were under construction: the Jasper–Ellijay segment and the northern half of the Blue Ridge–Tennessee segment.[4][5] By the end of 1929, two segments had a completed hard surface: a small portion just north of the Cobb–Cherokee county line and from a point northeast of Canton to just north of the Pickens–Gilmer county line. Two segments had a completed semi hard surface: nearly the entire Gilmer County portion of the Jasper–Ellijay segment (except for the extreme southern part) and the northern half of the Blue Ridge–Tennessee segment. The Ellijay–Blue Ridge segment was under construction.[5][6]

Question: When did construction on Georgia State Route 5 begin?

The Bionic Woman

To maintain the show's plausibility, creator/executive producer Kenneth Johnson set very specific limits on Jaime Sommers's abilities. He elaborated, "When you’re dealing with the area of fantasy, if you say, ‘Well, they’re bionic so they can do whatever they want,’ then it gets out of hand, so you’ve got to have really, really tight rules. [Steve and Jaime] can jump up two stories but not three. They can jump down three stories but not four. Jaime can’t turn over a truck but she can turn over a car."[4] These limits were occasionally incorporated into episodes, such as "Kill Oscar Part 1," in which Jaime is forced to make a jump that's too far down for her bionic legs, causing massive damage to them and nearly causing her death as a result.

Question: Who created the television series The Bionic Woman?
Answer: Kenneth Johnson

Oxygen

Oxygen was isolated by Michael Sendivogius before 1604, but it is commonly believed that the element was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774. Priority is often given for Priestley because his work was published first. Priestley, however, called oxygen "dephlogisticated air", and did not recognize it as a chemical element.  The name oxygen was coined in 1777 by Antoine Lavoisier, who first recognized oxygen as a chemical element and correctly characterized the role it plays in combustion.

Question: Who first identified oxygen?
Answer: Joseph Priestley

History of Madagascar

Europe knew of Madagascar through Arab sources; based on them The Travels of Marco Polo claimed that "the inhabitants are Saracens, or followers of the law of Mohammed", without mentioning other inhabitants. Other than its size and location, everything about the island in the book describes southeastern Africa, not Madagascar. European contact began on 10 August 1500, when the Portuguese sea captain Diogo Dias sighted the island after his ship separated from a fleet going to India.[49][4] The Portuguese continued trading with the islanders and named the island São Lourenço (Saint Lawrence). In 1666, François Caron, the director general of the newly formed French East India Company, sailed to Madagascar.[50] The company failed to establish a colony on Madagascar but established ports on the nearby islands of Bourbon (now Réunion) and Isle de France (now Mauritius). In the late 17th century, the French established trading posts along the east coast. On Île Sainte-Marie, a small island off the northeastern coast of Madagascar, Captain Misson and his pirate crew allegedly founded the famous pirate utopia of Libertatia in the late 17th century. From about 1774 to 1824, Madagascar was a favorite haunt for pirates.  Many European sailors were shipwrecked on the coasts of the island, among them Robert Drury, whose journal is one of the few written depictions of life in southern Madagascar during the 18th century.[51] Sailors sometimes called Madagascar "Island of the Moon".[52]

Question: Who was the first European to discover Madagascar?
Answer: Diogo Dias
Kodiak bear

An average adult male measures 244cm (8ft 0in) in length, and stands 133cm (4ft 4in) tall at the shoulder. The largest recorded wild male weighed 751kg (1,656lb), and had a hind foot measurement of 46cm (18in).[7] A large male Kodiak bear stands up to 1.5m (4.9ft) tall at the shoulder, when it is standing on all four legs. When standing fully upright on its hind legs, a large male could reach a height of 3m (9.8ft).[2] The largest verified size for a captive Kodiak bear was for a specimen that lived at the Dakota Zoo in Bismarck, North Dakota. Nicknamed "Clyde," he weighed 966kg (2,130lb) when he died in June 1987 at the age of 22. According to zoo director Terry Lincoln, Clyde probably weighed close to 1,090kg (2,400lb) a year earlier. He still had a fat layer of 9in (23cm) when he died.[8][lower-alpha 1]

Obsessive–compulsive disorder

A form of psychotherapy called "cognitive behavioral therapy" (CBT) and psychotropic medications are first-line treatments for OCD.[1][77] Other forms of psychotherapy, such as psychodynamic and psychoanalysis may help in managing some aspects of the disorder, but in 2007 the American Psychiatric Association (APA) noted a lack of controlled studies showing their effectiveness "in dealing with the core symptoms of OCD".[78] The fact that many individuals do not seek treatment may be due in part to stigma associated with OCD.

Question: What types of medications treats OCD?
Answer: psychotropic

Answer: cachaça (sugarcane hard liquor), sugar, and lime
Chemical compound

A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds. A chemical element bonded to an identical chemical element is not a chemical compound since only one element, not two different elements, is involved.

Answer: a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds. A chemical element bonded to an identical chemical element is not a chemical compound since only one element, not two different elements, is involved
Reflection seismology

The Canadian inventor Reginald Fessenden was the first to conceive of using reflected seismic waves to infer geology. His work was initially on the propagation of acoustic waves in water, motivated by the sinking of the Titanic by an iceberg in 1912. He also worked on methods of detecting submarines during World War I.  He applied for the first patent on a seismic exploration method in 1914, which was issued in 1917. Due to the war, he was unable to follow up on the idea. John Clarence Karcher discovered seismic reflections independently while working for the United States Bureau of Standards (now the National Institute of Standards and Technology) on methods of sound ranging to detect artillery.  In discussion with colleagues, the idea developed that these reflections could aid in exploration for petroleum.  With several others, many affiliated with the University of Oklahoma, Karcher helped to form the Geological Engineering Company, incorporated in Oklahoma in April, 1920.  The first field tests were conducted near Oklahoma City, Oklahoma in 1921.

Question: Who first developed reflection seismology?
Answer: 1917

SS Great Eastern

She also had six masts (said to be named after the days of a week – Monday being the fore mast and Saturday the spanker mast), providing space for 1,686 square metres (18,150sqft) of sails (7 gaff and max. 9 (usually 4) square sails), rigged similar to a topsail schooner with a main gaff sail (fore-and-aft sail) on each mast, one "jib" on the fore mast and three square sails on masts no. 2 and no. 3 (Tuesday & Wednesday); for a time mast no. 4 was also fitted with three yards. In later years, some of the yards were removed. According to some sources she would have carried 5,435 square metres (58,500sqft). This amount of canvas is obviously too much for seven fore-and-aft sails and max. 9 square sails. This (larger) figure of sail area lies only a few square metres below that the famous Flying P-Liner Preußen carried – with her five full-rigged masts of 30 square sails and a lot of stay sails. Setting sails turned out to be unusable at the same time as the paddles and screw were under steam, because the hot exhaust from the five (later four) funnels would set them on fire. Her maximum speed was 24km/h (13 knots).

Question: How fast could the SS Great Eastern go?
Answer: 24km/h
