9 Atholl Crescent In Edinburgh
9 (nine) is the natural number following and preceding . Evolution of the Arabic digit In the beginning, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an ascender in most modern typefaces, in typefaces with text figures the character usually has a descender, as, for example, in . The mod ...

Scottish Society Of Arts
The Royal Scottish Society of Arts is a learned society in Scotland, dedicated to the study of science and technology. It was founded as The Society for the Encouragement of the Useful Arts in Scotland by Sir David Brewster in 1821 and dedicated to ''"the promotion of invention and enterprise"''. The Society was granted a Royal Charter in 1841. Background For many years the promotion of invention and improvements of all sorts was the main business of the Society, and its meetings were the focus of a large and active cross-section of Edinburgh society - academics, gentry, professionals such as civil engineers and lawyers, and skilled craftsmen such as instrument makers, engravers and printers. The Society's published Transactions provide a record of changes in technology, and the Society's archive is held by the National Library of Scotland, and is a valuable resource to researchers. In more recent times, the Society's meeting programme has been based on lectures given by expert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineers From Edinburgh
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional pr ...

19th-century Scottish Scientists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dorothea Gerard
Dorothea Mary Stanislaus Gerard (Mme Longard de Longgarde, 9 August 1855 – 29 September 1915) was a Scottish-born novelist and romance-writer who often wrote about controversial and unconventional subjects and "whose general conservatism co-existed with a piercing eye for relations across national and ethnic divides, for antisemitism and other forms of prejudice." At first she wrote for pleasure with her less prolific older sister Emily Gerard but later carved an independent career publishing about forty books between 1890 and 1916 mostly for Tauchnitz editions signifying her target audience was mainly English-speaking visitors travelling in Europe.John Sutherland''The Stanford Companion to Victorian Fiction'' Stanford University Press (1989) - Google Books pgs. 242-243 Early life Dorothea Gerard was born in 1855 at Rochsoles House in New Monkland, Lanark, Scotland, the youngest daughter of Colonel Archibald Gerard (1812–1880) of Rochsoles, Lanarkshire, and Euphemia Erskine ...

Emily Gerard
(Jane) Emily Gerard (7 May 1849 – 11 January 1905) was a Scottish 19th-century author best known for the influence her collections of Transylvanian folklore had on Bram Stoker's 1897 novel ''Dracula''. Life Early life Emily Gerard was born on 7 May 1849 at Chesters, Jedburgh, Scotland, the oldest daughter of Colonel Archibald Gerard (1812–80) of Rochsoles, Lanarkshire and Euphemia Erskine (1818–70), daughter of the inventor Sir John Robison (1778–1843). She had three sisters and three brothers including General Sir Montagu Gilbert Gerard (1842–1905). She was descended from Alexander Gerard (1728–95) a philosophical writer, Archibald Alison (1757–1839) a Scottish Episcopalian minister and writer, and Gilbert Gerard (1760–1815) a minister of the Church of Scotland and theological writer. Her sister Dorothea, born on 9 August 1855 at New Monkland, Lanark, was also a novelist. In the 1861 Scotland Census, Gerard is recorded as living at Rochsoles House in Lan ...

Camera Lucida
A ''camera lucida'' is an optical device used as a drawing aid by artists and microscopists. The ''camera lucida'' performs an optical superimposition of the subject being viewed upon the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure. This allows the artist to duplicate key points of the scene on the drawing surface, thus aiding in the accurate rendering of perspective. History The ''camera lucida'' was patented in 1806 by the English chemist William Hyde Wollaston. The basic optics were described 200 years earlier by the German astronomer Johannes Kepler in his ''Dioptrice'' (1611), but there is no evidence he or his contemporaries constructed a working ''camera lucida''. By the 19th century, Kepler's description had fallen into oblivion, so Wollaston's claim was never challenged. The term "''camera lucida''" (Latin "well-lit room" as opposed to ''camera obscura'' "dark room") i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Lighting
Gas lighting is the production of artificial light from combustion of a gaseous fuel, such as hydrogen, methane, carbon monoxide, propane, butane, acetylene, ethylene, coal gas (town gas) or natural gas. The light is produced either directly by the flame, generally by using special mixes (typically propane or butane) of illuminating gas to increase brightness, or indirectly with other components such as the gas mantle or the limelight, with the gas primarily functioning as a heat source for the incandescence of the gas mantle or lime. Before electricity became sufficiently widespread and economical to allow for general public use, gas was the most prevalent method of outdoor and indoor lighting in cities and suburbs, areas where the infrastructure for distribution of the gaseous fuel was practical. When gas lighting was prevalent, the most common fuels for gas lighting were wood gas, coal gas and, in limited cases, water gas. Early gas lights were ignited manually by lampl ...

Gas Cooker
A gas stove is a stove that is fuelled by combustible gas such as syngas, natural gas, propane, butane, liquefied petroleum gas or other flammable gas. Before the advent of gas, cooking stoves relied on solid fuels such as coal or wood. The first gas stoves were developed in the 1821s and a gas stove factory was established in England in 1836. This new cooking technology had the advantage of being easily adjustable and could be turned off when not in use. The gas stove, however, did not become a commercial success until the 1885s, by which time supplies of piped gas were available in cities and large towns in Britain. The stoves became widespread on the European Continent and in the United States in the middle 20th century. Gas stoves became more common when the oven was integrated into the base and the size was reduced to better fit in with the rest of the kitchen furniture. By the 1910s, producers started to enamel their gas stoves for easier cleaning. Ignition of the gas was ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casters
A caster (or castor) is an undriven wheel that is designed to be attached to the bottom of a larger object (the "vehicle") to enable that object to be moved. Casters are used in numerous applications, including shopping carts, office chairs, toy wagons, hospital beds, and material handling equipment. High capacity, heavy duty casters are used in many industrial applications, such as platform trucks, carts, assemblies, and tow lines in plants. Types Casters may be fixed to roll along a straight line path, or mounted on a pivot or pintle such that the wheel will automatically align itself to the direction of travel. Rigid casters A basic, rigid caster consists of a wheel mounted to a stationary fork. The orientation of the fork, which is fixed relative to the vehicle, is determined when the caster is mounted to the vehicle. An example of this is the wheels found at the rear of a shopping cart in North America. Rigid casters tend to restrict vehicle motion so that the vehicle tra ...
