Silver Glen
The Silver Glen lies approximately to the east of the town of Alva, Clackmannanshire, Scotland, and takes its name from the silver that was mined there in the early 18th century. The deposit, the richest deposit of native silver ever found in the British Isles, was discovered just as the Jacobite rising of 1715 was breaking out, and its owner, Sir John Erskine, left to join the rebels, leaving his wife in charge of the mine. Some 40 tons of ore were raised and buried in barrels in the grounds of Alva House at the foot of the Ochil Hills, about east of Stirling, whilst the richest of the ore was smelted and the ingots concealed under floorboards inside the house. The mine was then filled in during the aftermath of the failed rising, but its existence was revealed to the government by an employee of the Erskines. Samples of the ore were analysed by Sir Isaac Newton and found to be very rich. Sir John was later able to secure a pardon for his role in the rising, on condition he rev ...

Silver Glen Road (geograph 2579426)
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''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. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes 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 the seven metals of antiquity, silver has had an enduring role in most human cultures.

Alva, Clackmannanshire
Alva (Scottish Gaelic: ''Ailbheach'', meaning rocky) is a small town in Clackmannanshire, set in the Central Lowlands of Scotland. It is one of a number of towns situated immediately to the south of the Ochil Hills, collectively referred to as the ''Hillfoots Villages'' or simply ''The Hillfoots''. It is located between Tillicoultry and Menstrie. Alva had a resident population of 5,181 at the 2001 census but this has since been revised to 4,600 in 2016. It boasts many features such as a park with an event hall and a newly opened outdoor gym, and is the home of Alva Academy. Etymology The name of this place, the orthography of which has successively passed through the different forms of Alueth, and Alvath or Alveth to that of Alva, is of Gaelic origin, and is supposed to be derived from the term ''Ailbheach'', signifying "rocky." History The old town centred on Alva House a tower house dating from 1542 and enlarged and remodelled in 1636 by Sir Charles Erskine. It remained ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Jacobite Rising Of 1715
The Jacobite rising of 1715 ( gd, Bliadhna Sheumais ; or 'the Fifteen') was the attempt by James Edward Stuart (the Old Pretender) to regain the thrones of England, Ireland and Scotland for the exiled Stuarts The House of Stuart, originally spelt Stewart, was a royal house of Scotland, England, Ireland and later Great Britain. The family name comes from the office of High Steward of Scotland, which had been held by the family progenitor Walter fi .... At Braemar, Aberdeenshire, local landowner the John Erskine, Earl of Mar (1675–1732), Earl of Mar raised the Jacobite standard on 27 August. Aiming to capture Stirling Castle, he was checked by the much-outnumbered Hanoverians, commanded by the John Campbell, 2nd Duke of Argyll, Duke of Argyll, at Sheriffmuir on 13 November. There was no clear result, but the Earl appeared to believe, mistakenly, that he had won the battle, and left the field.

Sir Isaac Newton
Sir Isaac Newton (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a "natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Enlightenment. His book (''Mathematical Principles of Natural Philosophy''), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus. In the , Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint for centuries until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erythrite
Erythrite or red cobalt is a secondary hydrated cobalt arsenate mineral with the formula . Erythrite and annabergite, chemical formula , or nickel arsenate form a complete series with the general formula . Erythrite crystallizes in the monoclinic system and forms prismatic crystals. The color is crimson to pink and occurs as a secondary coating known as ''cobalt bloom'' on cobalt arsenide minerals. Well-formed crystals are rare, with most of the mineral manifesting in crusts or small reniform aggregates. Erythrite was first described in 1832 for an occurrence in Grube Daniel, Schneeberg, Saxony, and takes its name from the Greek έρυθρος (''erythros''), meaning red. Historically, erythrite itself has not been an economically important mineral, but the prospector may use it as a guide to associated cobalt and native silver. Erythrite occurs as a secondary mineral in the oxide zone of Co–Ni–As bearing mineral deposits. It occurs in association with cobaltite, skutterud ...

Cobalt
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments ( cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was for a long time thought to be due to the known metal bismuth. Miners had long used the name ''kobold ore'' (German for ''goblin ore'') for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Woodland Trust
The Woodland Trust is the largest woodland conservation charity in the United Kingdom and is concerned with the creation, protection, and restoration of native woodland heritage. It has planted over 50 million trees since 1972. The Woodland Trust has three aims: to protect ancient woodland which is rare, unique and irreplaceable, to promote the restoration of damaged ancient woodland, and to plant native trees and woods to benefit people and wildlife. The Woodland Trust maintains ownership of over 1,000 sites covering over 24,700 hectares (247 km2). Of this, 8,070ha (33%) is ancient woodland. It ensures public access to its woods. History The charity was founded in Devon, England in 1972 by retired farmer and agricultural machinery dealer Kenneth Watkins. The Trust's first purchase was part of the Avon Valley Woods, near Kingsbridge, Devon. By 1977 it had 22 woods in six counties. In 1978 it relocated to Grantham in Lincolnshire and announced an expansion of its activit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Clackmannanshire
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Scotland
The geology of Scotland is unusually varied for a country of its size, with a large number of differing geological features.Keay & Keay (1994) page 415. There are three main geographical sub-divisions: the Highlands and Islands is a diverse area which lies to the north and west of the Highland Boundary Fault; the Central Lowlands is a rift valley mainly comprising Palaeozoic formations; and the Southern Uplands, which lie south of the Southern Uplands Fault, are largely composed of Silurian deposits. The existing bedrock includes very ancient Archean gneiss, metamorphic beds interspersed with granite intrusions created during the Caledonian mountain building period (the Caledonian orogeny), commercially important coal, oil and iron bearing carboniferous deposits and the remains of substantial Palaeogene volcanoes. During their formation, tectonic movements created climatic conditions ranging from polar to desert to tropical and a resultant diversity of fossil remains. Scotland h ...
