ﾃ四e Vierge
ﾃ四e 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 dﾃｩpartement of Finistﾃｨre. It is the location of the tallest stone lighthouse in Europe, and the tallest "traditional lighthouse" in the world. The International Hydrographic Organization specifies ﾃ四e 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 "ﾃ四e 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 Coﾃｫpel for 6,000 francs. The lighthouses The first lighthouse was a square tower high constructed in 1842窶45. It started operation on 15 August 1845, feast day of the Assumption of the Virgin. It had a fixed white light visible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breton Language
Breton (, ; or in Morbihan) is a Southwestern Brittonic language of the Celtic language family 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 branch instead of the 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 during the Early Middle Ages, making it an Insular Celtic language. Breton is most closely related to Cornish, another Southwestern Brittonic language. Welsh and the extinct Cumbric, both Western Brittonic languages, are more distantly related. Having declined from more than one million speakers around 1950 to about 200,000 in the first decade of the 21st century, Breton is classified as "severely endangered" by the UNESCO '' Atlas of the World's Languages in Danger''. However, the number of children attending bilingual classes rose 33 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focal Length
The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the 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 (parallel) rays are brought to a 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 most photography and all telescopy, where the subject is essentially infinitely far away, longer focal length (lower opti ...

Mercury (element)
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( ) from the Greek words, ''hydor'' (water) and ''argyros'' (silver). A heavy, silvery d-block A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-blo ... 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. Mercury is used in ...

Saint-Gobain
Compagnie de Saint-Gobain S.A. () is a French multinational corporation, founded in 1665 in Paris and headquartered on the outskirts of Paris, at La Dﾃｩfense and in Courbevoie. Originally a mirror manufacturer, it now also produces a variety of construction, high-performance, and other materials. History 1665-1789: Manufacture royale Since the middle of the 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, chﾃ｢teaux and ornate side tables and pier-tables were decorated with this expensive and luxurious product. 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 monopoly of the glass and mirror business. French minister of finance Olivier Bluche wanted France to become completely self-sufficient ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opaline Glass
The term "opaline" refers to a number of different styles of glassware. By opaline glass we mean a milky glass, which can be white or colored, and is made translucent or opaque by adding particular phosphates or oxides during the mixing. It can also have iris reflexes. In France, the term "opaline" is used to refer to multiple types of glass, and not specifically antique colored crystal or semi-crystal, as is commonly thought, with 'opaline' often a mistakenly-given term referring to the color of a particular type of glass, rather than the age, origin or content of the glass. Description To make the opaline glass, opacifying substances are added, such as: sodium phosphate, sodium chloride, calcium phosphate, calcium chloride, tin oxide and talc oxide. The glass can thus take on different colors and have varying shades of color, depending on the quantity of the added substance: from white to gray, to pink, to lavender green, to golden yellow, to light blue, up to blue and black. ...

Granite
Granite () is a coarse-grained (phaneritic) 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 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 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) contain almost no dark minerals. Granite is nearly alway ...

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).

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 reeds, a similar principle to a modern electric car horn. Others used air forced through holes in a rotating cylinder or disk, in the same manner as a 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 own timing characteristics to help marine ...

Assumption Of Mary
The Assumption of Mary is one of the four Marian dogmas of the Catholic Church. Pope Pius XII defined it in 1950 in his apostolic constitution ''Munificentissimus Deus'' as follows: We proclaim and define it to be a dogma revealed by God that the immaculate Mother of God, Mary ever virgin, when the course of her earthly life was finished, was taken up body and soul into the glory of heaven. The declaration was built upon the 1854 dogma of the Immaculate Conception of Mary, which declared that Mary was conceived free from original sin, and both have their foundation in the concept of Mary as the Mother of God. It leaves open the question of whether Mary died or whether she was raised to eternal life without bodily death. The equivalent belief (but not held as dogma) in the Eastern Orthodox Church 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 ''assﾅｫmptiﾅ'' meaning "taking up". T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 arose from the early Christian custom of commemorating each martyr annually on the date of their death, or 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 ...

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 ...
