Dual (mathematics)
In mathematics, a duality translates concepts, theorems or mathematical structures into other concepts, theorems or structures, in a one-to-one fashion, often (but not always) by means of an involution operation: if the dual of is , then the dual of is . Such involutions sometimes have fixed points, so that the dual of is itself. For example, Desargues' theorem is self-dual in this sense under the ''standard duality in projective geometry''. In mathematical contexts, ''duality'' has numerous meanings. It has been described as "a very pervasive and important concept in (modern) mathematics" and "an important general theme that has manifestations in almost every area of mathematics". Many mathematical dualities between objects of two types correspond to pairings, bilinear functions from an object of one type and another object of the second type to some family of scalars. For instance, ''linear algebra duality'' corresponds in this way to bilinear maps from pairs of vecto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dual-Ghia
Dual-Ghia is a rare, short-lived, automobile make, produced in the United States between 1956 and 1958. The idea for a sporty limited production car came from Eugene Casaroll, who controlled specialized vehicle builder Dual-Motors Corporation based in Detroit, Michigan; the name Dual-Ghia is representative of the collaborative efforts between the builder and Carrozzeria Ghia. Design The design for a luxurious sports car was to be a modified version of the Ghia-built 1954 and 1955 Dodge-based concept cars known as the Firearrow I, II, III, IV and the nearly production-ready Firebomb; which had all been designed by Luigi Segre with some possible influence from Virgil Exner. With so many cars designed along the same theme, Chrysler may well have intended to produce the Firebomb and/or the Chrysler Falcon as a response to the Ford Thunderbird and Chevrolet Corvette; for whatever reason neither made it to production. After gaining rights to the Firearrow/Firebomb design, Casaroll a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Duals
The Duals were an American surf rock duo formed in Los Angeles, California, in 1961. Much of the collaboration's music capitalized on the style of music popularized in Southern California in the early 1960s. They reached the national charts with their song "Stick Shift" which became the Duals' only Top 40 hit. A studio album named after the Duals' hit song was released the following year. History The Duals featured the partnership of Henry Bellinger (lead guitar) and Johnny Lageman (rhythm guitar), two friends who lived in the same neighborhood in Los Angeles. In 1961, the duo approached H.B. Barnum with hopes that the record producer would record them in Hollywood. Barnum, however, had little faith in the songs the Duals had written but recommended them to Ron Barrett, an aspiring producer who recently established his own record label, Star Revue. Barrett was more receptive to the duo's simple, but upbeat, sound influenced by California's burgeoning surf scene. After extensi ...

Dual (album)
''Dual'' is an album by four acclaimed Irish and Scottish musicians: Éamonn Doorley, Muireann Nic Amhlaoibh (both prominently of Danú), Julie Fowlis and Ross Martin. The artists released the album in October 2008 on their official websites. The album was planned to project the similarities and differences between the Irish and Scottish Gaelic song traditions. The album features Scottish waulking songs such as ''Alasdair Mhic Cholla Ghasda'', and an Irish equivalent to the Scottish puirt à beul. The songs are set in a traditional/folk accompaniment, very different from the recorded versions of a few of the songs by Capercaillie and Clannad. The four musicians have been playing music together since a sing-song at the Tønder Festival in 2003. The four-piece has toured together twice a year both in Ireland and Scotland. Julie and Muireann have had very similar upbringings and found their music and languages shared many common threads. Hence the name, ''Dual'', which means "to b ...
