Cincinnati Bengals

The Bengals were founded in 1966 as a member of the American Football League (AFL) by former Cleveland Browns head coach Paul Brown. Brown was the Bengals' head coach from their inception to 1975. After being dismissed as the Browns' head coach by Art Modell (who had purchased majority interest in the team in 1961) in January 1963, Brown had shown interest in establishing another NFL franchise in Ohio and looked at both Cincinnati and Columbus. He ultimately chose the former when a deal between the city, Hamilton County, and Major League Baseball's Cincinnati Reds (who were seeking a replacement for the obsolete Crosley Field) was struck that resulted in an agreement to build a multipurpose stadium which could host both baseball and football games.

Question: How old is the Cincinnati Bengals?
Answer: founded in 1966
IMSI-catcher

An international mobile subscriber identity-catcher, or IMSI-catcher, is a telephone eavesdropping device used for intercepting mobile phone traffic and tracking location data of mobile phone users.[1] Essentially a "fake" mobile tower acting between the target mobile phone and the service provider's real towers, it is an example of a man-in-the-middle (MITM) attack. The 3G wireless standard offers some risk mitigation due to mutual authentication required from both the handset and the network.[2] However, sophisticated attacks may be able to downgrade 3G and LTE to non-LTE network services which do not require mutual authentication.[3]

Question: What does "IMSI" stand for in IMSI-catcher?
Answer: international mobile subscriber identity-catcher
Jörmungandr

In Norse mythology, Jörmungandr (Old Norse: Jǫrmungandr, pronounced [ˈjɔrmunˌɡandr̥], meaning "huge monster"[1]), also known as the Midgard (World) Serpent (Old Norse: Miðgarðsormr), is a sea serpent, the middle child of the giantess Angrboða and Loki. According to the Prose Edda, Odin took Loki's three children by Angrboða—the wolf Fenrir, Hel, and Jörmungandr—and tossed Jörmungandr into the great ocean that encircles Midgard.[2] The serpent grew so large that he was able to surround the earth and grasp his own tail.[2] As a result, he received the name of the Midgard Serpent or World Serpent. When he releases his tail, Ragnarök will begin. Jörmungandr's arch-enemy is the thunder-god, Thor. It is an example of an ouroboros.

Question: Who is Jormungand's mother?
Answer: Angrboða

Australian Football League

The league currently consists of 18 teams spread over five of Australia's six states (Tasmania being the exception). Matches have been played in all states and mainland territories of Australia, as well as in New Zealand and China (although no professional teams or leagues exist outside Australia) to promote the sport abroad. The AFL season currently consists of a pre-season competition (currently branded as the "JLT Community Series"), followed by a 23-round regular (or "home-and-away") season, which runs during the Australian winter (March to September). The team with the best record after the home-and-away series is awarded the "minor premiership." The top eight teams then play off in a four-round finals series, culminating in the AFL Grand Final, which is held at the Melbourne Cricket Ground each year. The grand final winner is termed the "premiers", and is awarded the premiership cup. The current premiers are the West Coast Eagles.

Question: What is the biggest event in the Australian Football League?

KHON-TV

KHON-TV first signed on the air on December 15, 1952 as a primary NBC affiliate, KONA-TV, occupying the channel 11 position. It also had a secondary affiliation with DuMont (which it later shared with KULA-TV, now KITV, after it signed on in 1954) until its demise in 1955.[1] The station, which is Hawaii's second-oldest television station (behind KGMB, originally on channel 9, now on channel 5), was originally owned by Herbert Richards. Two years later in 1954, the Honolulu Advertiser purchased the station. On October 16, 1955, KONA changed channels from 11 to 2 due to the lower VHF positions (2 to 6) having the most powerful ERPs at the time. The channel 11 frequency now belongs to PBS member station KHET. In 1956, KONA was sold to Pacific and Southern Broadcasting, the forerunner of Combined Communications. KAII signed on in 1958, with KHAW following in 1961. In 1965, the station's call letters were changed to the current KHON-TV.

Sound recording and reproduction

The first practical sound recording and reproduction device was the mechanical phonograph cylinder, invented by Thomas Edison in 1877 and patented in 1878.[9][10] The invention soon spread across the globe and over the next two decades the commercial recording, distribution, and sale of sound recordings became a growing new international industry, with the most popular titles selling millions of units by the early 1900s. The development of mass-production techniques enabled cylinder recordings to become a major new consumer item in industrial countries and the cylinder was the main consumer format from the late 1880s until around 1910.

Question: Who invented the first audio recording device?
Answer: Thomas Edison
Ashton-Tate

In 1978 Martin Marietta programmer Wayne Ratliff wrote Vulcan, a database application, to help him make picks for football pools. Written in Intel 8080 assembly language, it ran on the CP/M operating system and was modeled on JPLDIS,[1] a Univac 1108 program used at JPL and written by fellow programmer Jeb Long. Ashton-Tate was launched as a result of George Tate and Hal Lashlee having discovered Vulcan from Ratliff in 1981 and licensing it (there was never any Ashton).  The original agreement was written on one page, and called for simple, generous royalty payments to Ratliff.

Heavy metal music

In a review of Sir Lord Baltimore's Kingdom Come in the May 1971 Creem, Saunders wrote, "Sir Lord Baltimore seems to have down pat most all the best heavy metal tricks in the book".[99] Creem critic Lester Bangs is credited with popularizing the term via his early 1970s essays on bands such as Led Zeppelin and Black Sabbath.[100] Through the decade, heavy metal was used by certain critics as a virtually automatic putdown. In 1979, lead New York Times popular music critic John Rockwell described what he called "heavy-metal rock" as "brutally aggressive music played mostly for minds clouded by drugs",[101] and, in a different article, as "a crude exaggeration of rock basics that appeals to white teenagers".[102]

Question: Why is heavy metal called heavy metal?
Answer: in the May 1971 Creem, Saunders wrote, "Sir Lord Baltimore seems to have down pat most all the best heavy metal tricks in the book".[99] Creem critic Lester Bangs is credited with popularizing the term via his early 1970s essays on bands such as Led Zeppelin and Black Sabbath
Yuma War

The Yuma War was the name given to a series of United States military operations conducted in southern California and what is today southwestern Arizona from 1850 to 1853. The Yumans were the primary opponent of the United States Army, though engagements were fought between the Americans and other native groups in the region. Conflict generally took the form of guerrilla warfare, and, over the course of three years, the army engaged in pursuing unfriendly natives, protecting American settlers crossing the Colorado River and preventing conflict between the native tribes. A peace treaty in summer of 1853 was signed, ending hostilities between the Yuma and the United States, but it sparked a short war between the Yuma and the Cocopah. During the conflict, the historic Fort Yuma was constructed and became an important outpost on the frontier.

Question: How long did The Yuma War go on for?
Answer: 1850 to 1853

Microglia

The ability to view and characterize different neural cells including microglia began in 1880 when Nissl staining was developed by Franz Nissl. Franz Nissl and F. Robertson first described microglial cells during their histology experiments. The cell staining techniques in the 1880s showed that microglia are related to macrophages. The activation of microglia and formation of ramified microglial clusters was first noted by Victor Babeş while studying a rabies case in 1897. Babeş noted the cells were found in a variety of viral brain infections but did not know what the clusters of microglia he saw were.[30] Pío del Río Hortega, a student of Santiago Ramón y Cajal, first called the cells "microglia" around 1920. He went on to characterize microglial response to brain lesions in 1927 and note the "fountains of microglia" present in the corpus callosum and other perinatal white matter areas in 1932. After many years of research Rio-Hortega became generally considered as the "Father of Microglia."[31][32] For a long period of time little improvement was made in our knowledge of microglia. Then, in 1988, Hickey and Kimura showed that perivascular microglial cells are bone-marrow derived, and express high levels of MHC class II proteins used for antigen presentation. This confirmed Pio Del Rio-Hortega's postulate that microglial cells functioned similarly to macrophages by performing phagocytosis and antigen presentation.

Question: How was microglia discovered?
Answer: 1880

Commonwealth of Independent States

The CIS has its origins in the Soviet Union (USSR), which was established by the 1922 Treaty and Declaration of the Creation of the USSR by the Russian SFSR, Byelorussian SSR and Ukrainian SSR.  When the USSR began to fall in 1991, the founding republics signed the Belavezha Accords on 8 December 1991, declaring the Soviet Union would cease to exist and proclaimed the CIS in its place.  A few days later the Alma-Ata Protocol was signed, which declared that Soviet Union was dissolved and that the Russian Federation was to be its successor state.  The Baltic states (Estonia, Latvia and Lithuania), which regard their membership in the Soviet Union as an illegal occupation, chose not to participate. Georgia withdrew its membership in 2008. Ukraine, which participated as an associate member, ended its participation in CIS statutory bodies on 19 May 2018.[3]
