Bishop Rock, Isles Of Scilly
The Bishop Rock () is a skerry off the British coast in the northern Atlantic Ocean known for its lighthouse. It is in the westernmost part of the Isles of Scilly, an archipelago off the southwestern tip of the Cornish peninsula of Great Britain. The ''Guinness Book of Records'' lists it as the world's smallest island with a building on it. The original iron lighthouse was begun in 1847 but was washed away before it could be completed. The present building was completed in 1858 and was first lit on 1September that year. Before the installation of the helipad, visitors to the lighthouse would rappel from the top (with winches installed at the lamp level and at the base below) to boats waiting away from the lighthouse. Bishop Rock is also at the eastern end of the North Atlantic shipping route used by ocean liners in the first half of the 20th century; the western end being the entrance to Lower New York Bay. This was the route that ocean liners took when competing for the tran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bishop Rock Lighthouse SV8006
A bishop is an ordained member of the clergy who is entrusted with a position of authority and oversight in a religious institution. In Christianity, bishops are normally responsible for the governance and administration of dioceses. The role or office of the bishop is called episcopacy or the episcopate. Organisationally, several Christian denominations utilise ecclesiastical structures that call for the position of bishops, while other denominations have dispensed with this office, seeing it as a symbol of power. Bishops have also exercised political authority within their dioceses. Traditionally, bishops claim apostolic succession, a direct historical lineage dating back to the original Twelve Apostles or Saint Paul. The bishops are by doctrine understood as those who possess the full priesthood given by Jesus Christ, and therefore may ordain other clergy, including other bishops. A person ordained as a deacon, priest (i.e. presbyter), and then bishop is understood to hold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloudesley Shovell
Admiral of the Fleet Sir Cloudesley Shovell ( – 22/23 October 1707) was an Royal Navy officer and politician. As a junior officer he saw action at the Battle of Solebay and Battle of Texel during the Third Anglo-Dutch War. As a captain he fought at the Battle of Bantry Bay during the Williamite War in Ireland. As a flag officer, Shovell commanded a division at the action at Barfleur during the Nine Years' War, and during the battle distinguished himself by being the first to break through the enemy's line. Along with Admiral Henry Killigrew and Admiral Ralph Delaval, Shovell was put in joint command of the fleet shortly afterwards. During the War of the Spanish Succession, Shovell commanded a squadron which served under Admiral George Rooke at the capture of Gibraltar and the Battle of Málaga.

Eddystone Lighthouse
The Eddystone Lighthouse is a lighthouse on the Eddystone Rocks, south of Rame Head in Cornwall, England. The rocks are submerged below the surface of the sea and are composed of Precambrian gneiss. View at 1:50000 scale The current structure is the fourth to be built on the site. The first lighthouse (Winstanley's) was swept away in a powerful storm, killing its architect and five other men in the process. The second (Rudyard's) stood for fifty years before it burned down. The third (Smeaton's) is renowned because of its influence on Lighthouse, lighthouse design and its importance in the development of concrete for building; its upper portions were re-erected in Plymouth as a monument. The first lighthouse, completed in 1699, was the world's first open ocean lighthouse, although the Cordouan Lighthouse off the western French coast preceded it as the first offshore lighthouse.

Duchy Of Cornwall
A duchy, also called a dukedom, is a country, territory, fief, or domain ruled by a duke or duchess, a ruler hierarchically second to the king or queen in Western European tradition. There once existed an important difference between "sovereign dukes" and dukes who were ordinary noblemen throughout Europe. Some historic duchies were sovereign in areas that would become part of nation-states only during the modern era, such as happened in Germany (once a federal empire) and Italy (previously a unified kingdom). In contrast, others were subordinate districts of those kingdoms that had unified either partially or completely during the medieval era, such as France, Spain, Sicily, Naples, and the Papal States. Examples In France, several duchies existed in the medieval period, including Normandy, Burgundy, Brittany, and Aquitaine. The medieval German stem duchies (, literally "tribal duchy," the official title of its ruler being '' Herzog'' or "duke") were associated with the Fran ...

Hyperradiant Fresnel Lens
Hyper-radial or hyperradiant Fresnel lenses are Fresnel lenses used in lighthouses. They are larger than First order Fresnel lens#Sizes of lighthouse lenses, "first-order" lenses, having a focal length (radius) of 1330 mm (52.36 inches). The idea was mentioned by Thomas Stevenson in 1869 and first proposed by John Richardson Wigham in 1872, and again proposed by Thomas Stevenson in 1885 (infringing Wigham's patent). The hyper-radial lens was made in 1885 by the Barbier, Benard, et Turenne, F. Barbier Company in Paris as a test lens for the lighthouse illumination trials then going on at the South Foreland Lighthouse in the United Kingdom (UK). Chance Brothers Glass Company made their first hyper-radial lens in 1887 in the UK. These lenses were originally named biform, and later triform and quadriform lenses, by Wigham. Thomas Stevenson used the term hyperradiant lens, and later they were renamed the hyper-radial lens by James Kenward of the Chance Brothers Glass Company. The ...

Barque
A barque, barc, or bark is a type of sailing ship, sailing vessel with three or more mast (sailing), masts of which the fore mast, mainmast, and any additional masts are Square rig, rigged square, and only the aftmost mast (mizzen in three-masted barques) is Fore-and-aft rig, rigged fore and aft. Sometimes, the mizzen is only partly fore-and-aft rigged, bearing a square-rigged sail above. Etymology The word "barque" entered English via the French term, which in turn came from the Latin language, Latin ''barca'' by way of Occitan language, Occitan, Catalan language, Catalan, Spanish, or Italian. The Latin may stem from Celtic language, Celtic ''barc'' (per Rudolf Thurneysen, Thurneysen) or Greek ''baris'' (per Friedrich Christian Diez, Diez), a term for an Egyptian boat. The ''Oxford English Dictionary'', however, considers the latter improbable. The word ''barc'' appears to have come from Celtic languages. The form adopted by English, perhaps from Irish language, Irish, was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Packet Boat
Packet boats were medium-sized boats designed mainly for domestic mail and freight transport in European countries and in North American rivers and canals. Eventually including basic passenger accommodation, they were used extensively during the 18th and 19th centuries, and had regularly scheduled services. In the 18th century, packet boats were put into use on the Atlantic Ocean between Kingdom of Great Britain, Great Britain and its colonies, where the services were called the packet trade. In the later 19th century, steam-driven packets were used extensively in the United States on the Mississippi River, Mississippi and Missouri River, Missouri rivers, supplying forts and trading posts. History Packet craft were used extensively in European coastal mail services since the 17th century, and gradually added minimal passenger accommodation: "firing" (i.e. a place to cook), drinking water (often tasting of indigo or tobacco, which the water casks had previously held), and a pla ...

Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine driving paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, whereby the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the propeller, screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Essaouira
Essaouira ( ; ), known until the 1960s as Mogador (, or ), is a port city in the western Moroccan region of Marrakesh-Safi, on the Atlantic coast. It has 77,966 inhabitants as of 2014. The foundation of the city of Essaouira was the work of the Moroccan 'Alawid sultan Mohammed bin Abdallah, who made an original experiment by entrusting it to several architects in 1760, in particular Théodore Cornut and Ahmed al-Inglizi, who designed the city using French captives from the failed French expedition to Larache in 1765, and with the mission of building a city adapted to the needs of foreign merchants. Once built, it continued to grow and experienced a golden age and exceptional development, becoming the country's most important commercial port but also its diplomatic capital between the end of the 18th century and the first half of the 19th century. Medina of Essaouira was designated by the UNESCO a World Heritage Site in 2001. Name and etymology The name of the city is ...

Dead Reckoning
In navigation, dead reckoning is the process of calculating the current position of a moving object by using a previously determined position, or fix, and incorporating estimates of speed, heading (or direction or course), and elapsed time. The corresponding term in biology, to describe the processes by which animals update their estimates of position or heading, is path integration. Advances in navigational aids that give accurate information on position, in particular satellite navigation using the Global Positioning System, have made simple dead reckoning by humans obsolete for most purposes. However, inertial navigation systems, which provide very accurate directional information, use dead reckoning and are very widely applied. Etymology Contrary to myth, the term "dead reckoning" was not originally used to abbreviate "deduced reckoning", nor is it a misspelling of the term "ded reckoning". The use of "ded" or "deduced reckoning" is not known to have appeared earlier th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
