Tennis court

A tennis court is the venue where the sport of tennis is played. It is a firm rectangular surface with a low net stretched across the center. The same surface can be used to play both doubles and singles matches. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game.

Dimensions

Tennis is played on a rectangular flat surface, usually of grass, clay or hard material. The dimensions of a tennis court are defined and regulated by the International Tennis Federation (ITF) governing body and are written down in the annual 'Rules of Tennis' document. The court is 78 feet (23.77 metres) long. Its width is 27 feet (8.23 metres) for singles matches and 36 feet (10.97 metres) for doubles matches. The service line is 21 feet (6.40 metres) from the net. Additional clear space around the court is needed in order for players to reach overrun balls for a total of 60 feet (18 metres) wide and 120 feet (37 metres) long. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. The net is 3 feet 6 inches (1.07 metres) high at the posts, and 3 feet (0.91 metres) high in the center. The net posts are 3 feet (0.91 metres) outside the doubles court on each side or, for a singles net, 3 feet (0.91 metres) outside the singles court on each side.

Tennis Court (song)

"Tennis Court" is a song by New Zealand singer Lorde, taken from her debut album Pure Heroine (2013). On 7 June 2013, the song was released as the album's second single by Universal Music Group, following "Royals". Tennis Court EP was also released, comprising three additional tracks. "Tennis Court" served as the fourth single from Pure Heroine in the United States. Written by Lorde and Joel Little and produced by Little, "Tennis Court" combines alternative pop, art pop and electropop genres with elements from downtempo, hip hop and EDM. It features synthesisers and electronic pulses in its composition. The lyrics address Lorde's new-found fame and criticise the "high life."

"Tennis Court" was well received by critics, who complimented the song's production and musical style. The single garnered success in Oceania, peaking at number one on the New Zealand singles chart and entering the top thirty chart in Australia. In Europe, it charted in Belgium (in both Flanders and Wallonia), France, the UK and Germany; the song also appeared on multiple US charts. "Tennis Court" was certified platinum by both the Australian Recording Industry Association and Recorded Music NZ. A music video for the song was directed by Joel Kefali and features Lorde staring into the camera during one continuous shot. To promote Pure Heroine and the song, Lorde performed "Tennis Court" several times, including on Live on Letterman.

Dublin

Dublin (/ˈdʌblᵻn/, Irish: Baile Átha Cliath [blʲaːˈklʲiəh]) is the capital and largest city of Ireland. Dublin is in the province of Leinster on Ireland's east coast, at the mouth of the River Liffey. The city has an urban area population of 1,273,069. The population of the Greater Dublin Area, as of 2011, was 1,801,040 persons.

Founded as a Viking settlement, the Kingdom of Dublin became Ireland's principal city following the Norman invasion. The city expanded rapidly from the 17th century and was briefly the second largest city in the British Empire before the Acts of Union in 1800. Following the partition of Ireland in 1922, Dublin became the capital of the Irish Free State, later renamed Ireland.

Dublin is administered by a City Council. The city is listed by the Globalization and World Cities Research Network (GaWC) as a global city, with a ranking of "Alpha-", placing it among the top thirty cities in the world. It is a historical and contemporary centre for education, the arts, administration, economy and industry.

Kingdom of Dublin

Norwegian Vikings invaded the territory around Dublin in the 9th century, establishing the Norse Kingdom of Dublin, the earliest and longest-lasting Norse kingdom in the British Isles, excepting the Kingdom of Mann and the Isles. This corresponded to most of present-day County Dublin. The Norse referred to the kingdom as Dyflin, which is derived from Irish Dubh Linn, meaning "black pool". The first reference to the Vikings comes from the Annals of Ulster and the first entry for 841 AD reads: "Pagans still on Lough Neagh". It is from this date onward that historians get references to ship fortresses or longphorts being established in Ireland. It may be safe to assume that the Vikings first over-wintered in 840–841 AD. The actual location of the longphort of Dublin is still a hotly debated issue. Norse rulers of Dublin were often co-kings, and occasionally also Kings of Jórvík in what is now Yorkshire.

Over time, the rulers of Dublin became increasingly Gaelicized. They began to exhibit a great deal of Gaelic and Norse cultural syncretism, and are often referred to as Norse-Gaels.

Dublin City (UK Parliament constituency)

Dublin City was an Irish Borough constituency in the House of Commons of the United Kingdom of Great Britain and Ireland. It comprised the city of Dublin in the county of Dublin, and was represented by two Members of Parliament from its creation in 1801 until 1885.

In 1885, Dublin City was split into four divisions which were separate single member constituencies: Dublin College Green, Dublin Harbour, Dublin St Stephen's Green and Dublin St Patrick's.

Boundaries

The city of Dublin was accounted a county of itself, although it remained connected with County Dublin for certain purposes. A Topographical Directory of Ireland, published in 1837, describes the Parliamentary history of the city.

The city returns two members to the Imperial parliament; the right of election, formerly vested in the corporation, freemen, and 40s. freeholders, has been extended to the £10 householders, and £20 and £10 leaseholders for the respective terms of 14 and 20 years, by the act of the 2nd of William IV., cap. 88. The number of voters registered at the first general election under that act was 7041, of which number, 5126 voted. The limits of the city, for electoral purposes, include an area of 3538 statute acres, the boundaries of which are minutely detailed in the Appendix; the number of freemen is about 3500, of whom 2500 are resident and 1000 non-resident, and the number of £10 houses is 16,000 : the sheriffs are the returning officers.
