Barns Ness Lighthouse
Barns Ness Lighthouse is from Dunbar and was constructed by the engineers and brothers David A. Stevenson and Charles Alexander Stevenson, cousins of the novelist Robert Louis Stevenson, between 1899 and 1901. Taking approximately 2½ years to construct, it was constructed from stone quarried from Craigree (near Cramond) and Barnton. In 1976 it was described as a tall tower, slightly tapered with a circular section having a circular lantern which has triangular panes and a domed roof. The keepers' cottages were, as is typical, one floored, flat roofed buildings which were coated with harling but had their quoins exposed. The lintel above the door to the lighthouse is dated 1901. Within the compound of the lighthouse there was also a sundial and a flagpole. The stone proved resilient during the Second World War, when the lighthouse was machine-gunned yet sustained no damage. The lighthouse was staffed by two lighthouse-keepers until 1966 when it was electrified, with a ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunbar
Dunbar () is a town on the North Sea coast in East Lothian in the south-east of Scotland, approximately east of Edinburgh and from the English border north of Berwick-upon-Tweed. Dunbar is a former royal burgh, and gave its name to an ecclesiastical and civil parish. The parish extends around east to west and is deep at its greatest extent, or , and contains the villages of West Barns, Belhaven, and East Barns (abandoned) and several hamlets and farms. The town is served by Dunbar railway station with links to Edinburgh and the rest of Scotland, as well as London and stations along the north-east England corridor. Dunbar has a harbour dating from 1574 and is home to the Dunbar Lifeboat Station, the second-oldest RNLI station in Scotland. Dunbar is the birthplace of the explorer, naturalist, and influential conservationist John Muir. The house in which Muir was born is located on the High Street, and has been converted into a museum. There is also a commemorative s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sundial
A sundial is a horological device that tells the time of day (referred to as civil time in modern usage) when direct sunlight shines by the apparent position of the Sun in the sky. In the narrowest sense of the word, it consists of a flat plate (the ''dial'') and a gnomon, which casts a shadow onto the dial. As the Sun appears to move through the sky, the shadow aligns with different hour-lines, which are marked on the dial to indicate the time of day. The ''style'' is the time-telling edge of the gnomon, though a single point or ''nodus'' may be used. The gnomon casts a broad shadow; the shadow of the style shows the time. The gnomon may be a rod, wire, or elaborately decorated metal casting. The style must be parallel to the axis of the Earth's rotation for the sundial to be accurate throughout the year. The style's angle from horizontal is equal to the sundial's geographical latitude. The term ''sundial'' can refer to any device that uses the Sun's altitude or azimut ...

Lighthouses Completed In 1901
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Lighthouses In Scotland
This is a list of lighthouses in Scotland. The Northern Lighthouse Board, from which much of the information is derived, are responsible for most lighthouses in Scotland but have handed over responsibility in the major estuaries to the port authorities. Many of the more minor lights are not shown. A lighthouse that is no longer operating is indicated by the date of closure in the ''operated by'' column. Where two dates are shown, the lighthouse has been rebuilt. Nearly all the lighthouses in this list were designed by and most were built by four generations of one family, including Thomas Smith, who was both the stepfather and father-in-law of Robert Stevenson. Robert's sons and grandsons not only built most of the lights, often under the most appalling of conditions, but pioneered many of the improvements in lighting and signalling that cut down the enormous loss of life in shipping around the coasts of Scotland. The table may be sorted by any column by clicking on the headin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

Candlepower
Candlepower (abbreviated as cp or CP) is a unit of measurement for luminous intensity. It expresses levels of light intensity relative to the light emitted by a candle of specific size and constituents. The historical candlepower is equal to 0.981 candelas. In modern usage, ''candlepower'' is sometimes used as a synonym for ''candela''. History The term candlepower was originally defined in the United Kingdom, by the Metropolitan Gas Act 1860, as the light produced by a pure spermaceti candle that weighs and burns at a rate of . Spermaceti is a material from the heads of sperm whales, and was once used to make high-quality candles. At the time the UK established candlepower as a unit, the French standard of light was based on the illumination from a Carcel burner. They defined the unit was that illumination that emanates from a lamp burning pure colza oil (obtained from the seed of the plant '' Brassica campestris'') at a defined rate. Ten standard candles equaled about one Car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery (electricity)
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used ...

Backup Generator
An emergency power system is an independent source of electrical power that supports important electrical systems on loss of normal power supply. A standby power system may include a standby generator, batteries and other apparatus. Emergency power systems are installed to protect life and property from the consequences of loss of primary electric power supply. It is a type of continual power system. They find uses in a wide variety of settings from homes to hospitals, scientific laboratories, data centers, telecommunication equipment and ships. Emergency power systems can rely on Engine-generator, generators, deep-cycle battery, deep-cycle batteries, flywheel energy storage or fuel cells. History Emergency power systems were used as early as World War II on naval ships. In combat, a ship may lose the function of its boilers, which power the steam turbines for the Electrical generator, ship's generator. In such a case, one or more diesel engines are used to drive back-up genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouse-keeper
A lighthouse keeper or lightkeeper is a person responsible for tending and caring for a lighthouse, particularly the light and lens in the days when oil lamps and clockwork mechanisms were used. Lighthouse keepers were sometimes referred to as "wickies" because of their job trimming the wicks. Duties and functions Historically, lighthouse keepers were needed to trim the wicks, replenish fuel, wind clockworks and perform maintenance tasks such as cleaning lenses and windows. They were also responsible for the fog signal and the weather station, and played a major role in search and rescue at sea. Because most lighthouses are located in remote, isolated or inaccessible areas on islands and coastlines, it was typical for the work of lighthouse keeper to remain within a family, passing from parents to child, all of whom lived in or near the lighthouse itself. "Stag light" was an unofficial term given to some isolated lighthouses in the United States Lighthouse Service. It meant sta ...

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
