ÃŽle Vierge
Île Vierge (Breton language: ''Enez-Werc'h'') is a islet lying off the north-west coast of Brittany, opposite the village of Lilia. It is in the commune of Plouguerneau, in the département of Finistère. It is the location of the tallest stone lighthouse in Europe, and the tallest "traditional lighthouse" in the world. The International Hydrographic Organization specifies Île Vierge as marking the south-western limit of the English Channel. History About 1450, the Conventual Franciscans established an abbey on the island. The name "Île Vierge" probably comes from a chapel dedicated to the Blessed Virgin Mary. In 1507, the monks moved to Aber Wrac'h on the mainland. In 1844, the French state purchased the island from sieur Goyon de Coëpel for 6,000 francs. The lighthouses The first lighthouse was a square tower high constructed in 1842–45. It started operation on 15 August 1845, feast day of the Assumption of the Virgin. It had a fixed white light visible fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breton Language
Breton (, , ; or in Morbihan) is a Southwestern Brittonic language of the Celtic languages, Celtic language group spoken in Brittany, part of modern-day France. It is the only Celtic language still widely in use on the European mainland, albeit as a member of the Insular Celtic languages, insular branch instead of the extinct Continental Celtic languages, continental grouping. Breton was brought from Great Britain to Armorica (the ancient name for the coastal region that includes the Brittany peninsula) by migrating Britons (Celtic people), Britons during the Early Middle Ages, making it an Insular Celtic language. Breton is most closely related to Cornish language, Cornish, another Southwestern Brittonic language. Welsh language, Welsh and the extinct Cumbric language, Cumbric, both Western Brittonic languages, are more distantly related, and the Goidelic languages (Irish language, Irish, Manx language, Manx, Scottish Gaelic) have a slight connection due to both of their origi ...

Focal Length
The focal length of an Optics, optical system is a measure of how strongly the system converges or diverges light; it is the Multiplicative inverse, inverse of the system's optical power. A positive focal length indicates that a system Convergence (optics), converges light, while a negative focal length indicates that the system Divergence (optics), diverges light. A system with a shorter focal length bends the Ray (optics), rays more sharply, bringing them to a focus in a shorter distance or diverging them more quickly. For the special case of a thin lens in air, a positive focal length is the distance over which initially Collimated beam, collimated (parallel) rays are brought to a Focus (optics), focus, or alternatively a negative focal length indicates how far in front of the lens a point source must be located to form a collimated beam. For more general optical systems, the focal length has no intuitive meaning; it is simply the inverse of the system's optical power. In mos ...

Mercury (element)
Mercury is a chemical element; it has Symbol (chemistry), symbol Hg and atomic number 80. It is commonly known as quicksilver. A Heavy metal element, heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Exposure to mercury and mercury-containing organic compounds is toxic to the nervous system, immune system and kidneys of humans and other animals; mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury) either directly or through mechanisms of biomagnification. Mercu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint-Gobain
Compagnie de Saint-Gobain S.A. () is a French multinational corporation, founded in 1665 in Paris as the Manufacture royale de glaces de miroirs, and today headquartered on the outskirts of Paris, at La Défense and in Courbevoie. Originally a mirror manufacturer, it also produces a variety of construction, high-performance, and other materials. Saint-Gobain is present in 76 countries and employs more than 170,000 people. History 1665–1789: Manufacture royale Since the mid-17th century, luxury products such as silk textiles, lace, and mirrors were in high demand. In the 1660s, mirrors had become very popular among the upper classes of society: Italian cabinets, châteaux, ornate side tables, and pier-tables were decorated with these expensive and luxurious products. At the time, however, the French were not known for mirror technology; instead, the Republic of Venice was known as the world leader in glass manufacturing, controlling a technical and commercial monopol ...

Opaline Glass
Opaline glass is a style of antique glassware that was produced in Europe, particularly 19th-century France. It was originally made by adding materials such as bone ash to lead-crystal, creating a semi-opaque glass with reddish opalescence. Description Opaline glass gets its distinctive iridescent milkiness from opacifying substances added during the mixing process, including sodium phosphate, sodium chloride, calcium phosphate, calcium chloride, tin oxide and talc. The glass can thus take on different colors and present variable shades, depending on the mixture and quantity of opacifying material substance: from white to gray, to pink, to lavender green, to golden yellow, to light blue, up to blue and black. History The first opaline glass was made in Murano in the sixteenth century, with the addition of calcium phosphate, resulting from the calcination of bones. The technique did not remain secret and was copied in Germany, where this glass was known as (). Opaline glass was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite ( ) is a coarse-grained (phanerite, phaneritic) intrusive rock, intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dike (geology), dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF diagram, QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Beacon
In navigation, a radio beacon or radiobeacon is a kind of beacon, a device that marks a fixed location and allows direction-finding equipment to find relative bearing. But instead of employing visible light, radio beacons transmit electromagnetic radiation in the radio wave band. They are used for direction-finding systems on ships, aircraft and vehicles. Radio beacons transmit a continuous or periodic radio signal with limited information (for example, its identification or location) on a specified radio frequency. Occasionally, the beacon's transmission includes other information, such as telemetric or meteorological data. Radio beacons have many applications, including air and sea navigation, propagation research, robotic mapping, radio-frequency identification (RFID), near-field communication (NFC) and indoor navigation, as with real-time locating systems (RTLS) like Syledis or simultaneous localization and mapping (SLAM). Types Radio-navigation beacons The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foghorn
A foghorn or fog signal is a device that uses sound to warn vehicles of navigational hazards such as rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used in relation to marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rock outcrops, shoals, headlands, or other dangers to shipping. Description All foghorns use a vibrating column of air to create an audible tone, but the method of setting up this vibration differs. Some horns, such as the Daboll trumpet, used vibrating plates or metal reed (music), reeds, a similar principle to a modern electric Vehicle horn, car horn. Others used air forced through holes in a rotating cylinder or disk, in the same manner as a siren (alarm), siren. Semi-automatic operation of foghorns was achieved by using a clockwork mechanism (or "coder") to sequentially open the valves admitting air to the horns; each horn was given its ...

Assumption Of Mary
The Assumption of Mary is one of the four Catholic Mariology#Dogmatic teachings, Marian dogmas of the Catholic Church. Pope Pius XII defined it on 1 November 1950 in his apostolic constitution as follows: It leaves open the question of whether Mary died or whether she was raised to Eternal life (Christianity), eternal life without bodily death. The equivalent belief in the Eastern Christianity is the Dormition of the Mother of God or the "Falling Asleep of the Mother of God". The word 'assumption' derives from the Latin word , meaning 'taking up'. Pope Pius XII expressed in his encyclical ''Munificentissimus Deus'' the hope that the belief in the bodily assumption of the virgin Mary into heaven "will make our belief in our own resurrection stronger and render it more effective", while the Catechism of the Catholic Church adds: "The Assumption of the Blessed Virgin is a singular participation in her Son's Resurrection and an anticipation of the resurrection of other Chri ...

Feast Day
The calendar of saints is the traditional Christian method of organizing a liturgical year by associating each day with one or more saints and referring to the day as the feast day or feast of said saint. The word "feast" in this context does not mean "a large meal, typically a celebratory one", but instead "an annual religious celebration, a day dedicated to a particular saint". The system rose from the early Christian custom of commemorating each martyr annually on the date of their death, their birth into heaven, a date therefore referred to in Latin as the martyr's ''dies natalis'' ('day of birth'). In the Eastern Orthodox Church, a calendar of saints is called a ''Menologion''. "Menologion" may also mean a set of icons on which saints are depicted in the order of the dates of their feasts, often made in two panels. History As the number of recognized saints increased during Late Antiquity and the first half of the Middle Ages, eventually every day of the year had at l ...

Phare De L'Ile Vierge
The Phare programme is one of the three pre-accession instruments financed by the European Union to assist the applicant countries of Central and Eastern Europe in their preparations for joining the European Union. Originally created in 1989 as the Poland and Hungary: Assistance for Restructuring their Economies (PHARE) programme, Phare expanded from Poland and Hungary to cover ten countries. It assisted eight of the ten 2004 accession member states: the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, and Slovenia, as well as those countries that acceded in 2007 (Bulgaria and Romania), in a period of massive economic restructuring and political change. ''Phare'' means 'lighthouse' in French. Until 2000, countries of the Western Balkans (Albania, North Macedonia, and Bosnia-Herzegovina) were also beneficiaries of Phare. However, as of 2001, the CARDS programme (Community Assistance for Reconstruction, Development and Stability in the Balkans) has provided ...
