Engineer's Chain
The chain is a unit of length equal to 66 feet (22 yards). It is subdivided into 100 links (PDF) or 4 rods. There are 10 chains in a furlong, and 80 chains in one statute mile. In metric terms, it is 20.1168 m long. By extension, chainage (running distance) is the distance along a curved or straight survey line from a fixed commencing point, as given by an odometer. The chain has been used for several centuries in England and in some other countries influenced by English practice. In the United Kingdom, there were 80 chains to the mile, but until the early nineteenth century the Scottish and Irish customary miles were longer than the statute mile; consequently a Scots chain was about 74 (imperial) feet, an Irish chain 84 feet. These longer chains became obsolete following the adoption of the imperial system of units in 1824. Definition The UK statute chain is 22 yards, which is .

Imperial Units
The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial system developed from earlier English units as did the related but differing system of customary units of the United States. The imperial units replaced the Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, but imperial units are still used alongside metric units in the United Kingdom and in some other parts of the former empire, notably Canada. The modern UK legislation defining the imperial system of units is given in the Weights and Measures Act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statute Measure
Weights and measures acts are acts of the British Parliament determining the regulation of weights and measures. It also refers to similar royal and parliamentary acts of the Kingdoms of England and Scotland and the medieval Welsh states. The earliest of these were originally untitled but were given descriptive glosses or titles based upon the monarch under whose reign they were promulgated. Several omnibus modern acts are entitled the Weights and Measures Act and are distinguished by the year of their enactment. Background There have been many laws concerned with weights and measures in the United Kingdom or parts of it over the last 1,000 or so years. The acts may catalogue lawful weights and measures, prescribe the mechanism for inspection and enforcement of the use of such weights and measures and may set out circumstances under which they may be amended. Modern legislation may, in addition to specific requirements, set out circumstances under which the incumbent mini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keynsham
Keynsham ( ) is a town and civil parish located between Bristol and Bath in Somerset, England. It has a population of 16,000. It was listed in the Domesday Book as ''Cainesham'' (as it is pronounced), which is believed to mean the home of Saint Keyne. The site of the town has been occupied since prehistoric times, and may have been the site of the Roman settlement of Trajectus. The remains of at least two Roman villas have been excavated, and an additional 15 Roman buildings have been detected beneath the Keynsham Hams. Keynsham developed into a medieval market town after Keynsham Abbey was founded around 1170. It is situated at the confluence of the River Chew and River Avon and was subject to serious flooding before the creation of Chew Valley Lake and river level controls at Keynsham Lock in 1727. The Chew Stoke flood of 1968 inundated large parts of the town. It was home to the Cadbury's chocolate factory, Somerdale, which opened in 1935 as a major employer in the tow ...

Bridge Miles And Chains
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Ordinance Of 1785
The Land Ordinance of 1785 was adopted by the United States Congress of the Confederation on May 20, 1785. It set up a standardized system whereby settlers could purchase title to farmland in the undeveloped west. Congress at the time did not have the power to raise revenue by direct taxation, so land sales provided an important revenue stream. The Ordinance set up a survey system that eventually covered over three-quarters of the area of the continental United States. The earlier Land Ordinance of 1784 was a resolution written by Thomas Jefferson calling for Congress to take action. The land west of the Appalachian Mountains, north of the Ohio River and east of the Mississippi River was to be divided into ten separate states. However, the 1784 resolution did not define the mechanism by which the land would become states, or how the territories would be governed or settled before they became states. The Ordinance of 1785 put the 1784 resolution in operation by providing a mechanis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental Congress
The Continental Congress was a series of legislative bodies, with some executive function, for thirteen of Britain's colonies in North America, and the newly declared United States just before, during, and after the American Revolutionary War. The term "Continental Congress" most specifically refers to the First and Second Congresses of 1774–1781 and, at the time, was also used to refer to the Congress of the Confederation of 1781–1789, which operated as the first national government of the United States until being replaced under the Constitution of the United States. Thus, the term covers the three congressional bodies of the Thirteen Colonies and the new United States that met between 1774 and 1789. The First Continental Congress was called in 1774 in response to growing tensions between the colonies culminating in the passage of the Intolerable Acts by the British Parliament. It met for about six weeks and sought to repair the fraying relationship between Britain and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Jefferson
Thomas Jefferson (April 13, 1743 – July 4, 1826) was an American statesman, diplomat, lawyer, architect, philosopher, and Founding Fathers of the United States, Founding Father who served as the third president of the United States from 1801 to 1809. He was previously the nation's second vice president of the United States, vice president under John Adams and the first United States Secretary of State, United States secretary of state under George Washington.

Cadastral
A cadastre or cadaster is a comprehensive recording of the real estate or real property's metes-and-bounds of a country.Jo Henssen, ''Basic Principles of the Main Cadastral Systems in the World,'/ref> Often it is represented graphically in a cadastral map. In most countries, legal systems have developed around the original administrative systems and use the cadastre to define the dimensions and location of land parcels described in legal documentation. A land parcel or cadastral parcel is defined as "a continuous area, or more appropriately volume, that is identified by a unique set of homogeneous property rights". Cadastral surveys document the Boundary (real estate), boundaries of land ownership, by the production of documents, diagrams, sketches, plans (''plats'' in the US), charts, and maps. They were originally used to ensure reliable facts for land valuation and taxation. An example from early England is the Domesday Book in 1086. Napoleon established a comprehensive c ...

Gunter's Chain
Gunter's chain (also known as Gunter’s measurement) is a distance measuring device used for surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). It enabled plots of land to be accurately surveyed and plotted, for legal and commercial purposes. Gunter developed an actual measuring chain of 100 links. These, the chain and the link, became statutory measures in England and subsequently the British Empire. Description The chain is divided into 100 links, usually marked off into groups of 10 by brass rings or tags which simplify intermediate measurement. Each link is thus long. A quarter chain, or 25 links, measures and thus measures a rod (or pole). Ten chains measure a furlong and 80 chains measure a statute mile. Gunter's chain reconciled two seemingly incompatible systems: the traditional English land measurements, based on the number four, and decimals based on the number 10. Since an acre measured 1 ...

John Ogilby
John Ogilby (also ''Ogelby'', ''Oglivie''; November 1600 – 4 September 1676) was a Scottish translator, impresario and cartographer. Best known for publishing the first British road atlas, he was also a successful translator, noted for publishing his work in handsome illustrated editions. He also established Ireland's first theatre on Dublin's Werburgh Street. Life Ogilby was born in or near Killemeare (Kirriemuir), Scotland in November 1600. When his father was made a prisoner within the jurisdiction of the King's Bench, presumably for bankruptcy or debt, young John supported the family and used some of the money he earned to buy two lottery tickets, which won him a minor prize. This he used to apprentice himself to a dancing master and to obtain his father's release. By further good management of his finances, he was able to buy himself an early completion of his apprenticeship and set up a dancing school of his own. However, a fall while dancing in a masque lamed him fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edmund Gunter
Edmund Gunter (158110 December 1626), was an English clergyman, mathematician, geometer and astronomer of Welsh descent. He is best remembered for his mathematical contributions which include the invention of the Gunter's chain, the Gunter's quadrant, and the Gunter's scale. In 1620, he invented the first successful analogue device which he developed to calculate logarithmic tangents. He was mentored in mathematics by Reverend Henry Briggs and eventually became a Gresham Professor of Astronomy, from 1619 until his death. Biography Gunter was born in Hertfordshire in 1581. He was educated at Westminster School, and in 1599 he matriculated at Christ Church, Oxford. He took orders, became a preacher in 1614, and in 1615 proceeded to the degree of bachelor in divinity. He became rector of St. George's Church in Southwark. Mathematics, particularly the relationship between mathematics and the real world, was the one overriding interest throughout his life. In 1619, Sir Henry Sav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymath
A polymath ( el, πολυμαθής, , "having learned much"; la, homo universalis, "universal human") is an individual whose knowledge spans a substantial number of subjects, known to draw on complex bodies of knowledge to solve specific problems. In Western Europe, the first work to use the term polymathy in its title () was published in 1603 by Johann von Wowern, a Hamburg philosopher. Von Wowern defined polymathy as "knowledge of various matters, drawn from all kinds of studies ... ranging freely through all the fields of the disciplines, as far as the human mind, with unwearied industry, is able to pursue them". Von Wowern lists erudition, literature, philology, philomathy, and polyhistory as synonyms. The earliest recorded use of the term in the English language is from 1624, in the second edition of ''The Anatomy of Melancholy'' by Robert Burton; the form ''polymathist'' is slightly older, first appearing in the ''Diatribae upon the first part of the late History ...
