George Brown (inventor)
George Brown (1650–1730) was a Scotland, Scottish arithmetician, and inventor of two incomplete mechanical calculating machines now kept at the Museum of Scotland, National Museum of Scotland. In 1698 he was granted a patent for his mechanical calculating device. He was minister of Stranraer, schoolmaster in Fordyce, Aberdeenshire, Fordyce, Banffshire, and in 1680 schoolmaster at Kilmaurs, Ayrshire. He invented a method of teaching the simple rules of arithmetic, which he explained in his ''Rotula Arithmetica'', 1700. He wrote other arithmetical works; the last of them, ''Arithmetica Infinita'', was endorsed by John Keill.

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 ...

Arithmetician
Arithmetic () is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers— addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today. History The prehistory of arithmetic is limited to a small number of artifacts, which may indicate the conception of addition and subtraction, the best-known being the Ishango bone from central Africa, dating from somewhere between 20,000 and 18,000 BC, although its interpretation is disputed. The earliest written records indicate the Egyptians and Babylonians used all the elementary arithmetic operations: addition, subtraction, multiplication, and division, as early as 2000 BC. These artifacts do not always reveal the specific process used for solving problems, but t ...

Mechanical Calculating Machine
A mechanical calculator, or calculating machine, is a mechanical device used to perform the basic operations of arithmetic automatically, or (historically) a simulation such as an analog computer or a slide rule. Most mechanical calculators were comparable in size to small desktop computers and have been rendered obsolete by the advent of the electronic calculator and the digital computer. Surviving notes from Wilhelm Schickard in 1623 reveal that he designed and had built the earliest of the modern attempts at mechanizing calculation. His machine was composed of two sets of technologies: first an abacus made of Napier's bones, to simplify multiplications and divisions first described six years earlier in 1617, and for the mechanical part, it had a dialed pedometer to perform additions and subtractions. A study of the surviving notes shows a machine that would have jammed after a few entries on the same dial, and that it could be damaged if a carry had to be propagated over a f ...

Museum Of Scotland
The National Museum of Scotland in Edinburgh, Scotland, was formed in 2006 with the merger of the new Museum of Scotland, with collections relating to Scottish antiquities, culture and history, and the adjacent Royal Scottish Museum (opened in 1866 as the Edinburgh Museum of Science and Art, renamed in 1904, and for the period between 1985 and the merger named the Royal Museum of Scotland or simply the Royal Museum), with international collections covering science and technology, natural history, and world cultures. The two connected buildings stand beside each other on Chambers Street, by the intersection with the George IV Bridge, in central Edinburgh. The museum is part of National Museums Scotland. Admission is free. The two buildings retain distinctive characters: the Museum of Scotland is housed in a modern building opened in 1998, while the former Royal Museum building was begun in 1861 and partially opened in 1866, with a Victorian Venetian Renaissance facade and a gr ...

Fordyce, Aberdeenshire
Fordyce is a village in Aberdeenshire, Scotland that is slightly inland from the point where the Burn of Fordyce meets the sea between Cullen and Portsoy. It has existed since at least the 13th century. In 1990, Charles McKean wrote that Fordyce was "a sheer delight to discover, concealed as it is from the passing eye by hills and rolling countryside". The Kirkton of Fordyce was erected into a Burgh of Barony in 1499 by Bishop William Elphinstone of Aberdeen. Fordyce Parish Church, a fair distance from the village centre, dates to 1804. Its predecessor, St Talorgan Parish Church, has a belfry dating to 1661. Fordyce Castle Fordyce Castle, a T-plan structure built in 1592 and extended in 1700, lies in the centre of the village. Fordyce Academy Until 1964, the village had a notable secondary school called Fordyce Academy, which although small achieved high standards. Old boys of the school included the physicist and meteorologist Alexander Geddes, the zoologist William Dawson ...

Kilmaurs
Kilmaurs () is a village in East Ayrshire, Scotland which lies just outside of the largest settlement in East Ayrshire, Kilmarnock. It lies on the Carmel Water, southwest of Glasgow. Population recorded for the village in the 2001 Census recorded 2,601 people resided in the village It was in the Civil Parish of Kilmaurs. History Kilmaurs was known as the hamlet of Cunninghame until the 13th century.Groome, Francis H. (1903). ''Ordnance Gazetteer of Scotland.'' Pub. Caxton. London. P. 938.Tranter, Nigel (1965), ''The Fortified House in Scotland. V. 3. South-West Scotland.'' Pub. Oliver & Boyd. P. 40. The population in 1874 was 1,145. Alex Young suggested that the name Kilmaurs comes from the Gaelic meaning Hill of the Great Cairn.Young, Alex F.(2001). Old Kilmaurs and Fenwick. . Young’s suggestion for the Gaelic origins of the placename Kilmaurs is extremely unlikely. Earliest medieval records refer to an early medieval church dedicated to a saint (probably a Saint Maura) c ...

New Statistical Account Of Scotland
The ''Statistical Accounts of Scotland'' are a series of documentary publications, related in subject matter though published at different times, covering life in Scotland in the 18th, 19th and 20th centuries. The ''Old (or First) Statistical Account of Scotland'' was published between 1791 and 1799 by Sir John Sinclair of Ulbster. The ''New (or Second) Statistical Account of Scotland'' published under the auspices of the General Assembly of the Church of Scotland between 1834 and 1845. These first two Statistical Accounts of Scotland are among the finest European contemporary records of life during the agricultural and industrial revolutions. A ''Third Statistical Account of Scotland'' was published between 1951 and 1992. Early attempts Attempts at getting an accurate picture of the geography, people and economy of Scotland had been attempted in the 1620s and 1630s, using the network of about 900 ministers of the established Church of Scotland. The time and resources inv ...

Hew Scott
Hew Scott (1791–1872) was a minister of the Church of Scotland parish of Anstruther Wester. He is largely remembered as a religious researcher and author. His "magnum opus" is the comprehensive, multi-volume work, ''Fasti Ecclesiae Scoticanae: The succession of ministers in the parish churches of Scotland, from the reformation, A.D. 1560, to the present time''. This is a detailed, biographical record of each of the ministers of each of the parishes of the Church of Scotland from 1560 to 1870. (It also refers to earlier priests/ministers, where possible). It was first published between 1866 and 1871 but it is regularly updated by the Church of Scotland. The project took him 50 years and covered 760 parishes (often with more than one church per parish), including parishes which were either gone, amalgamated or fleeting in existence. Volume 1 was in part aided by Dr Gordon of Newbattle, Dr Struthers of Prestonpans and David Laing. Profits from the book went to the Ministers' Da ...
