James Bowman Lindsay
James Bowman Lindsay (8 September 1799 – 29 June 1862) was a Scottish inventor and author. He is credited with early developments in several fields, such as incandescent lighting and telegraphy. Life and work James Bowman Lindsay was born in Cotton of West Hills, Carmyllie near Arbroath in Angus, Scotland, son of John Lindsay, farm worker, and Elizabeth Bowman. During his childhood he was trained as a handloom weaver. However at the same time he educated himself and his parents recognised their son's potential. As a result, they saved enough money to be able to send him to St. Andrews University where he matriculated in 1821. As a student he soon made a name for himself in the fields of mathematics and physics and, after completing an additional course of studies in theology, he finally returned to Dundee in 1829 as Science and Mathematics Lecturer at the Watt Institution. Among his technological innovations, which were not developed until long after his death, are the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carmyllie
Carmyllie (Gaelic: ''Càrn Mhoillidh'') is a rural parish in Angus, Scotland. It is situated on high ground between Arbroath, on the coast, and the inland county town of Forfar. The main settlements in the parish are Redford, Greystone, Guynd and Milton of Carmyllie. There is a Church of Scotland church and a primary school. The Elliot Water rises in the west of the parish. Economy Carmyllie was formerly known for its stone quarries. For many centuries these produced high quality sandstone that was shipped all over the world. Carmyllie post office was closed in September 2008. Between 1900 and 1965 Carmyllie was linked to Arbroath by the |
Incandescent Light Bulb
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting. Incandescent bulbs are much less efficient than other types of electric lighting, converting le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alumni Of The University Of St Andrews
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating ( Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from th ...

Scottish Inventors
Scottish inventions and discoveries are objects, processes or techniques either partially or entirely invented, innovated, or discovered by a person born in or descended from Scotland. In some cases, an invention's Scottishness is determined by the fact that it came into existence in Scotland (e.g., animal cloning), by non-Scots working in the country. Often, things that are discovered for the first time are also called " inventions" and in many cases there is no clear line between the two. The Scots take enormous pride in the history of Scottish invention and discovery. There are many books devoted solely to the subject, as well as scores of websites listing Scottish inventions and discoveries with varying degrees of science. Even before the Industrial Revolution, Scots have been at the forefront of innovation and discovery across a wide range of spheres. Some of the most significant products of Scottish ingenuity include James Watt's steam engine, improving on that of Thomas ...

Lightning Conductor
A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it will preferentially strike the rod and be conducted to ground through a wire, instead of passing through the structure, where it could start a fire or cause electrocution. Lightning rods are also called finials, air terminals, or strike termination devices. In a lightning protection system, a lightning rod is a single component of the system. The lightning rod requires a connection to earth to perform its protective function. Lightning rods come in many different forms, including hollow, solid, pointed, rounded, flat strips, or even bristle brush-like. The main attribute common to all lightning rods is that they are all made of conductive materials, such as copper and aluminum. Copper and its alloys are the most common materials used in lightning protection. History The principle of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arc Welding
Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick (" electrode") and the base material to melt the metals at the point of contact. Arc welders can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated. First developed in the late part of the 19th century, arc welding became commercially important in shipbuilding during the Second World War. Today it remains an important process for the fabrication of steel structures and vehicles. Power supplies To supply the electrical energy necessary for arc welding proce ...

Submarine Telegraphy
A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables laid beginning in the 1850s carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fibre technology to carry digital data, which includes telephone, Internet and private data traffic. Modern cables are typically about in diameter and weigh around for the deep-sea sections which comprise the majority of the run, although larger and heavier cables are used for shallow-water sections near shore. Submarine cables first connected all the world's continents (except Antarctica) when Java was connected to Darwin, Northern Terri ...

Angus, Scotland
Angus ( sco, Angus; gd, Aonghas) is one of the 32 local government council areas of Scotland, a registration county and a lieutenancy area. The council area borders Aberdeenshire, Dundee City and Perth and Kinross. Main industries include agriculture and fishing. Global pharmaceuticals company GSK has a significant presence in Montrose in the north of the county. Angus was historically a province, and later a sheriffdom and county (known officially as Forfarshire from the 18th century until 1928), bordering Kincardineshire to the north-east, Aberdeenshire to the north and Perthshire to the west; southwards it faced Fife across the Firth of Tay; these remain the borders of Angus, minus Dundee which now forms its own small separate council area. Angus remains a registration county and a lieutenancy area. In 1975 some of its administrative functions were transferred to the council district of the Tayside Region, and in 1995 further reform resulted in the establishme ...

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 ...

Arbroath
Arbroath () or Aberbrothock ( gd, Obar Bhrothaig ) is a former royal burgh and the largest town in the council area of Angus, Scotland, with a population of 23,902. It lies on the North Sea coast some ENE of Dundee and SSW of Aberdeen. There is evidence of Iron Age settlement, but its history as a town began with the founding of Arbroath Abbey in 1178. It grew much during the Industrial Revolution through the flax and then the jute industry and the engineering sector. A new harbour created in 1839; by the 20th century, Arbroath was one of Scotland's larger fishing ports. It is notable for the Declaration of Arbroath and the Arbroath smokie. Arbroath Football Club holds the world record for the number of goals scored in a professional football match: 36–0 against Bon Accord of Aberdeen in the Scottish Cup in 1885 History Toponymy The earliest recorded name was 'Aberbrothock', referring to the Brothock Burn that runs through the town.
