Drag racing is a competition in which specially prepared automobiles or motorcycles compete, usually two at a time, to be the first to cross a set finish line. The race follows a straight course from a standing start over a measured distance, most commonly ¼ mile (1,320 ft (400 m)) for most cars, with a shorter 1,000 ft (300 m) for Top Fuel dragsters and funny cars. Electronic timing and speed sensing systems have been used to record race results since the 1960s.
Before each race (also known as a pass), each driver is allowed to perform a burnout, which heats the driving tires and lays rubber down at the beginning of the track, improving traction. Each driver then lines up (or stages) at the starting line. Races are started electronically by a system known as a Christmas tree. The Christmas tree consists of a column of lights for each driver/lane, one blue, then three amber, one green, and one red, connected to light beams on the track. The first, a split blue open circle, is split into two halves. When the first light beam is broken by the vehicle's front tire(s) indicate that the driver has pre-staged (approximately 7 inches (180 mm) from the starting line), lights the first half of the blue circle, and then staged (at the starting line), which lights up the second half of the blue circle, and also the corresponding bar in the middle of that circle.
The Irish people (Irish: Muintir na hÉireann or na hÉireannaigh; Ulster-Scots: Airisch or Airish fowk) are an ethnic group who originate in Ireland, an island in northwestern Europe. Ireland has been populated for around 9,000 years (according to archaeological studies, see Prehistoric Ireland). The Irish people's earliest ancestors are recorded in legends – they are claimed to be descended from groups such as the Nemedians, Fomorians, Fir Bolg, Tuatha Dé Danann and the Milesians.Lebor Gabála Érenn, a book of Irish mythology tells that Tuatha Dé Dananns were Scythian descendants.
The main groups that interacted with the Irish in the Middle Ages include the Picts, Scots, and the Vikings. Due to this contact, Icelanders are noted for having some Irish descent. The Anglo-Norman invasion of the High Middle Ages, the English plantations and the subsequent English rule of the country introduced the Normans and Flemish into Ireland. Welsh, Picts, Bretons, and small parties of Gauls and even Anglo-Saxons are known in Ireland from much earlier times.
