Existential quantification

In predicate logic, an existential quantification is a type of quantifier, a logical constant which is interpreted as "there exists", "there is at least one", or "for some".

It is usually denoted by the turned E (∃) logical operator symbol, which, when used together with a predicate variable, is called an existential quantifier ("∃x" or "∃(x)"). Existential quantification is distinct from universal quantification ("for all"), which asserts that the property or relation holds for all members of the domain.

Symbols are encoded U+2203 ∃ THERE EXISTS (HTML ∃ · ∃ · as a mathematical symbol) and U+2204 ∄ THERE DOES NOT EXIST (HTML ∄).

Basics

Consider a formula that states that some natural number multiplied by itself is 25.

This would seem to be a logical disjunction because of the repeated use of "or". However, the "and so on" makes this impossible to integrate and to interpret as a disjunction in formal logic. Instead, the statement could be rephrased more formally as

Something (TVXQ song)

"Something" is a song by South Korean pop duo TVXQ, also known as Tohoshinki in Japan. Serving as the lead single for their seventh Korean studio album Tense (2014), the song was produced by TVXQ's long-time collaborator Yoo Young-jin and co-written by Yoo with his brother Yoo Han-jin. Introduced as TVXQ's tenth anniversary comeback single, "Something" was released by S.M. Entertainment on January 6, 2014. Two versions of the song exist; the original Korean-language version, and a Japanese-language version, which was released by Avex Trax as a double A-sided CD single, along with "Hide & Seek", in Japan on February 5, 2014. It served as the fourth and final single release for the duo's seventh Japanese studio album, Tree (2014). Within a week of its release, the single was certified gold by the Recording Industry Association of Japan (RIAJ) for shipments of over 100,000.

Noted for being a major musical departure from TVXQ's earlier songs, "Something" is a song that incorporates swing performance styles with modern dance-pop. The song deals with a narcissistic male protagonist who tells women that they need to have "that something" in order to attract him. The accompanying music video, filmed in early December 2013, premiered on January 1, 2014 at 6pm KST.

Something (Shirley Bassey album)

Something is a 1970 album by Shirley Bassey. With her career having been in decline since the latter part of the mid 1960s, Something proved to be Shirley Bassey's comeback when it was released in August 1970. The title track single became her biggest UK hit for many years, reaching No.4 and spending 22 weeks on the chart. This was actually the second single featured on the album, "The Sea and Sand" having already been released earlier. The album was similarly her biggest hit for many years in the album charts, reaching No.5 and spending 28 weeks in the top 50.

This album led to a major revival in Bassey's career, and it would see Bassey transform into mainly an album artist, recording fifteen albums in the 1970s (four of those live recordings). Of those three would be top ten albums, three others in the top fifteen, and a further four in the top 40. She would also reach the top three twice, with a pair of compilations. (UK Albums Chart)

This was also her first work with record producer Noel Rogers and producer/arranger Johnny Harris, who built on Bassey's traditional pop roots to include contemporary songs and arrangements.

Gouais blanc

Gouais blanc (French pronunciation: ​[ɡu.ɛ blɑ̃]) or Weißer Heunisch (German pronunciation: [ˈvaɪsɐ ˈhɔʏnɪʃ]) is a white grape variety that is seldom grown today but is important as the ancestor of many traditional French and German grape varieties. The name Gouais derives from the old French adjective ‘gou’, a term of derision befitting its traditional status as the grape of the peasants. Likewise, the German name Weißer Heunisch labels it as one the lesser, Hunnic grapes.

History

Gouais is known to have been widely planted in central and northeastern France in Medieval times. At this time, it was used to produce simple, acidic white wines, and were primarily grown in less good plots that were not suited for the much more highly regarded Pinot noir or Pinot gris. Gouais Blanc was thus the grape of the peasantry rather than of the nobility.

Its history before Medieval times is not known with any certainty, but is the subject of much conjecture, in similarity to many other grape varieties with a long history. Gouais blanc has been proposed as a candidate for the grape given to the Gauls by Marcus Aurelius Probus (Roman Emperor 276–282), who was from Pannonia and who overturned Domitian's decree banning grape growing north of the Alps. Another hypothesis claims it originates specifically in Croatia (or Pannonia), but the Vitis International Variety Catalogue currently lists it as originating from Austria, which should probably be interpreted as "likely to originate somewhere in Central Europe".
