Irrational number

In mathematics, the irrational numbers are all the real numbers which are not rational numbers, the latter being the numbers constructed from ratios (or fractions) of integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure"), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.

Special Air Service

The Special Air Service (SAS) is a special forces unit of the British Army. The SAS was founded in 1941 as a regiment, and later reconstituted as a corps in 1950.[5] The unit undertakes a number of roles including covert reconnaissance, counter-terrorism, direct action and hostage rescue. Much of the information and actions regarding the SAS is highly classified, and is not commented on by the British government or the Ministry of Defence due to the sensitivity of their operations.[10][11][12]

Botulinum toxin

In 1820, Justinus Kerner, a small-town German medical officer and romantic poet, gave the first complete description of clinical botulism based on extensive clinical observations of so-called “sausage poisoning”.[38] Following experiments on animals and on himself, he concluded that the toxin acts by interrupting signal transmission in the somatic and autonomic motor systems, without affecting sensory signals or mental functions. He observed that the toxin develops under anaerobic conditions, and can be lethal in minute doses.[39] His prescience in suggesting that the toxin might be used therapeutically earned him recognition as the pioneer of modern botulinum toxin therapy.[40]

Question: When was Botox first introduced?

Frustration–aggression hypothesis

Frustration–aggression hypothesis, otherwise known as the frustration–aggression–displacement theory, is a theory of aggression proposed by John Dollard, Neal Miller, Leonard Doob, Orval Mowrer, and Robert Sears in 1939,[1] and further developed by Neal Miller in 1941[2] and Leonard Berkowitz in 1969.[3] The theory says that aggression is the result of blocking, or frustrating, a person's efforts to attain a goal.[4]

Question: When did John Dollard propose the frustration–aggression–displacement theory?

Sneakers

These shoes acquired the nickname 'plimsoll' in the 1870s, derived according to Nicholette Jones' book The Plimsoll Sensation, from the coloured horizontal band joining the upper to the sole, which resembled the Plimsoll line on a ship's hull. Alternatively, just like the Plimsoll line on a ship, if water got above the line of the rubber sole, the wearer would get wet.[7]

Question: When were athletic sneakers first used?
Dissenting opinion

A dissenting opinion (or dissent) is an opinion in a legal case in certain legal systems written by one or more judges expressing disagreement with the majority opinion of the court which gives rise to its judgment. When not necessarily referring to a legal decision, this can also be referred to as a minority report.[1][2]

Brown v. Board of Education

Brown v. Board of Education of Topeka, 347 U.S. 483 (1954),[1] was a landmark United States Supreme Court case in which the Court declared state laws establishing separate public schools for black and white students to be unconstitutional. The decision effectively overturned the Plessy v. Ferguson decision of 1896, which allowed state-sponsored segregation, insofar as it applied to public education. Handed down on May 17, 1954, the Warren Court's unanimous (9–0) decision, which was partially influenced by Mendez v. Westminster, stated that "separate educational facilities are inherently unequal." As a result, de jure racial segregation was ruled a violation of the Equal Protection Clause of the Fourteenth Amendment of the United States Constitution. This ruling paved the way for integration and was a major victory of the Civil Rights Movement,[2] and a model for many future impact litigation cases.[3] However, the decision's fourteen pages did not spell out any sort of method for ending racial segregation in schools, and the Court's second decision in Brown II (349U.S.(1955)) only ordered states to desegregate "with all deliberate speed".

Question: When was the video game Rock Band first introduced?

Hydraulic fracturing

Hydraulic fracturing (also fracking, fraccing, frac'ing, hydrofracturing or hydrofracking) is a well stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open.[1]

Question: What kind of drill is used in fracking?

Georgetown Hoyas

The University admits that the precise origin of the term "Hoya" is unknown.[3] At some point before 1893, and likely before 1891, students versed in classical languages combined the Greek hoia or hoya, meaning "what" or "such", and the Latin saxa to form Hoya Saxa!, or "What Rocks!"[4][5] This cheer may either refer to the stalwart defense of the football team, or to the baseball team, which was nicknamed the "Stonewalls", or to the actual stone wall that surrounds the campus.[6] Father William McFadden, S.J., campus Jesuit and the team's in-house announcer at the Capital One Arena, has disputed the Greek and Latin origin, suggesting the classical words were retroactively applied to a nonsensical cheer.[5]

Question: What is the origin of the "Hoyas" of Georgetown University?

HTTPS

Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP) for secure communication over a computer network, and is widely used on the Internet.[1][2] In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS), or, formerly, its predecessor, Secure Sockets Layer (SSL). The protocol is therefore also often referred to as HTTP over TLS,[3] or HTTP over SSL.

Caravaggio

Michelangelo Merisi (Michele Angelo Merigi or Amerighi) da Caravaggio (/ˌkærəˈvædʒioʊ/, US: /-ˈvɑːdʒ-/, Italian pronunciation:[mikeˈlandʒelo meˈriːzi da (k)karaˈvaddʒo]; 28 September 1571[2] – 18 July 1610) was an Italian painter active in Rome, Naples, Malta, and Sicily from the early 1590s to 1610. His paintings combine a realistic observation of the human state, both physical and emotional, with a dramatic use of lighting, which had a formative influence on Baroque painting.[3][4][5]

Theatre of Dionysus

The Theatre of Dionysus Eleuthereus is a major theatre in Athens, considered to be the world's first theatre, built at the foot of the Athenian Acropolis. Dedicated to Dionysus, the god of plays and wine (among other things), the theatre could seat as many as 17,000 people with excellent acoustics,[1] making it an ideal location for ancient Athens' biggest theatrical celebration, the Dionysia.  It was the first  theatre ever built, cut into the southern cliff face of the Acropolis, and supposedly the birthplace of Greek tragedy. The remains of a restored and redesigned Roman version can still be seen at the site today. It is sometimes confused with the later, smaller, and better-preserved Odeon of Herodes Atticus, located nearby on the southwest slope of the Acropolis.

Question: What is the oldest surviving theater in the world?

History of the transistor

The first patent[1] for the field-effect transistor principle was filed in Canada by Austrian-Hungarian physicist Julius Edgar Lilienfeld on October 22, 1925, but Lilienfeld published no research articles about his devices, and his work was ignored by industry. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor.[2] There is no direct evidence that these devices were built, but later work in the 1990s show that one of Lilienfeld's designs worked as described and gave substantial gain. Legal papers from the Bell Labs patent show that William Shockley and a co-worker at Bell Labs, Gerald Pearson, had built operational versions from Lilienfeld's patents, yet they never referenced this work in any of their later research papers or historical articles.[3]

Question: When were transistors first invented?

Early history of video games

Following the 1947 invention of the cathode-ray tube amusement device, the earliest known interactive electronic game as well as the first to use an electronic display, the first true video games were created in the early 1950s. Initially created as technology demonstrations, such as the Bertie the Brain and Nimrod computers in 1950 and 1951, video games also became the purview of academic research. A series of games, generally simulating real-world board games, were created at various research institutions to explore programming, human–computer interaction, and computer algorithms. These include OXO and Christopher Strachey's draughts program in 1952, the first software-based games to incorporate a CRT display, and several chess and checkers programs. Possibly the first video game created simply for entertainment was 1958's Tennis for Two, featuring moving graphics on an oscilloscope. As computing technology improved over time, computers became smaller and faster, and the ability to work on them was opened up to university employees and undergraduate students by the end of the 1950s. These new programmers began to create games for non-academic purposes, leading up to the 1962 release of Spacewar! as one of the earliest known digital computer games to be available outside a single research institute.

Question: What was the first video game ever released?

Vatican City

The Holy See dates back to early Christianity, and is the primate episcopal see of the Catholic Church, with 1.3billion Catholics around the world distributed in the Latin Church and 23 Eastern Catholic Churches. The independent Vatican City-state, on the other hand, came into existence in 11 February 1929 by the Lateran Treaty between the Holy See and Italy, which spoke of it as a new creation,[12] not as a vestige of the much larger Papal States (756–1870), which had previously encompassed much of central Italy.

Question: When did the Vatican become an independent city-state?

Boston Tea Party

The Boston Tea Party was a political and mercantile protest by the Sons of Liberty in Boston, Massachusetts, on December 16, 1773.[1] The target was the Tea Act of May 10, 1773, which allowed the British East India company to sell tea from China in American colonies without paying taxes apart from those imposed by the Townshend Acts. American Patriots strongly opposed the taxes in the Townshend Act as a violation of their rights.  Demonstrators, some disguised as Native Americans, destroyed an entire shipment of tea sent by the East India Company.

Question: When was the Boston Tea Party?

History of Maryland

In 1781, during the American Revolutionary War (1775–1783), Maryland became the thirteenth state of the United States to ratify the Articles of Confederation and Perpetual Union.  They were drawn up by a committee of the Second Continental Congress (1775–1781), which began shortly after the adoption of a Declaration of Independence in July 1776, through to 1778. Later that year, these Articles were recommended to the newly independent sovereign states via their legislatures for the required unanimous ratification. This long process was held up for three years by objections from smaller states led by Maryland until certain issues and principles over the western lands beyond  the Appalachian Mountains to the Mississippi River. These objections were resolved with the larger states agreeing to cede their various western claims to the authority of the new Congress of the Confederation, representing all the states, to be held in common for the laying out and erection of new states out of the jointly held Federal territories. Maryland then finally agreed to join the new American confederation by being one of the last of the former colonies ratifying the long proposed Articles in 1781, when they took effect.

Question: When was Maryland established?
Microwave oven

In 1947, Raytheon built the "Radarange", the first commercially available microwave oven.[13] It was almost 1.8 metres (5ft 11in) tall, weighed 340 kilograms (750lb) and cost about US$5,000 ($56,000 in 2018 dollars) each. It consumed 3 kilowatts, about three times as much as today's microwave ovens, and was water-cooled. The name was the winning entry in an employee contest.[14] An early Radarange was installed (and remains) in the galley of the nuclear-powered passenger/cargo ship NS Savannah. An early commercial model introduced in 1954 consumed 1.6 kilowatts and sold for US$2,000 to US$3,000 ($19,000 to $28,000 in 2018 dollars). Raytheon licensed its technology to the Tappan Stove company of Mansfield, Ohio in 1952.[15] They tried to market a large 220 volt wall unit as a home microwave oven in 1955 for a price of US$1,295 ($12,000 in 2018 dollars), but it did not sell well.

Question: How much did the first microwave oven cost?

Timeline of the Portolá expedition

Question: How many ships were involved in the Portolà expedition?

Battle of Chosin Reservoir

Roy E. Appleman, the author of US Army official history South to Naktong, North to Yalu, writes that both sides could claim victory: the PVA 9th Army ultimately held the battlefield, while X Corps held off the Chinese 9th Army in a series of battles that enabled it to withdraw most of its forces as an effective tactical unit.[1]:355–6 Allan R. Millett qualifies a Chinese "geographic victory" that ejected X Corps from North Korea with the fact that the Chinese failed to achieve the objective of destroying the 1st Marine Division, adding that the campaign gave the UN confidence that it could withstand the superior numbers of the Chinese forces.[49] The official Chinese history, published by PLA Academy of Military Science, states that despite the heavy casualties, the PVA 9th Army had earned its victory by successfully protecting the eastern flank of Chinese forces in Korea, while inflicting over 10,000 casualties to the UN forces.[50]
