Douglas Head Lighthouse
Douglas Head Lighthouse is a lighthouse at Douglas Head on the Isle of Man located between England and Ireland. The lighthouse was established in 1857, although the vicinity was under the control of the Isle of Man Harbour Board from 1832. It was made by the engineering brothers David and Thomas Stevenson with a total elevation of . The white tower is in height and its base is at an elevation of . The lighthouse staircase has 71 steps and the light has an average range of . The lantern is composed of eight brilliant reflectors made of pure silver built in 1831. The light flashes white every ten seconds. History Structural problems required the lighthouse to be rebuilt in 1892. The lighthouse became automated in 1986. Recently, a new public footpath was constructed by the Commissioners from the top of Port Skillion down to the Lighthouse for the benefit and enjoyment of tourists and sightseers. Ownership After the establishment of the new lighthouse in 1857, jurisdiction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas, Isle Of Man
Douglas ( gv, Doolish, ) is the capital and largest town of the Isle of Man, with a population of 26,677 (2021). It is located at the mouth of the River Douglas, and on a sweeping bay of . The River Douglas forms part of the town's harbour and main commercial port. Douglas was a small settlement until it grew rapidly as a result of links with the English port of Liverpool in the 18th century. Further population growth came in the following century, resulting during the 1860s in a staged transfer of the High Courts, the Lieutenant Governor's residence, and finally the seat of the legislature, Tynwald, to Douglas from the ancient capital, Castletown. The town is the Island's main hub for business, finance, legal services, shipping, transport, shopping, and entertainment. The annual Isle of Man TT motorcycle races start and finish in Douglas. History Early history In the absence of any archaeological data, the origins of the town may be revealed by analysis of the origina ...

Lighthouses In The Isle Of Man
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

Manx People
The Manx (; gv, ny Manninee) are an ethnic group originating on the Isle of Man in the Irish Sea in northern Europe. Their native culture has significant Norse-Gaels, Norse-Gaelic, Celts, Celtic, and English people, English influences. The Manx language descends from Middle Irish. Isle of Man demographics According to the 2011 interim census, the Isle of Man is home to 84,655 people, of whom 26,218 reside in the island's capital Douglas, Isle of Man, Douglas (''Doolish''). The largest proportion of the population was born on the island, but major settlement by English people (''Sostnee'') and others has significantly altered the demographics. According to the 2011 census, 47.6% were born in the Isle of Man, and 37.2% were born in England, with smaller numbers born elsewhere: 3.4% in Scotland, 2.1% in Northern Ireland, 2.1% in the Republic of Ireland, 1.2% in Wales and 0.3% born in the Channel Islands, with 6.1% of the population having been born elsewhere in the world.

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Lighthouse Board
The Northern Lighthouse Board (NLB) is the general lighthouse authority for Scotland and the Isle of Man. It is a non-departmental public body responsible for marine navigation aids around coastal areas. History The NLB was formed by Act of Parliament in 1786 as the Commissioners of Northern Light Houses, largely at the urging of the lawyer and politician George Dempster ("Honest George"), to oversee the construction and operation of four Scottish lighthouses: Kinnaird Head, North Ronaldsay, Scalpay and Mull of Kintyre, for which they were empowered to borrow up to £1,200. Until then, the only major lighthouse in Scotland was the coal brazier mounted on the Isle of May in the Firth of Forth, together with some smaller lights in the Firths of the Tay and Clyde. None of the major passages around Scotland, which led through dangerous narrows, were marked. The commissioners, whose first president was the Lord Provost of Edinburgh, Sir James Hunter-Blair, advertised for buildin ...
