John Caulfield Hannyngton
John Caulfield Hannyngton (7 March 1807 – 1885 or 1886) was a British military commander, actuary and mathematician. He is remembered as inventor of a slide rule of previously unattainable precision. History Hannyngton was born in Dungannon, County Tyrone, Ireland, a son of Thomas Knox Hannyngton and Mrs Hannyngton, née Caulfield or Caulfeild. He joined the British Army as a cadet in 1825 and was posted to India with the 24th Regiment of Native Infantry. On the suppression of the Colekan rebellion in 1839 he was given a political appointment, and in 1842 promoted to Judicial Commissioner. He was promoted to Lieutenant-Colonel in 1856 and took command of the 63rd RNI. At the time of the Indian mutiny of 1857 he was with his regiment, which was disarmed but did not rebel. He was transferred to the Military Finance Department on the strength of his competence with figures, and finally promoted to Military Auditor-General which post he held until 1861 when he retired. He is b ...

Slide Rule
The slide rule is a mechanical analog computer which is used primarily for multiplication and division, and for functions such as exponents, roots, logarithms, and trigonometry. It is not typically designed for addition or subtraction, which is usually performed using other methods. Maximum accuracy for standard linear slide rules is about three decimal significant digits, while scientific notation is used to keep track of the order of magnitude of results. Slide rules exist in a diverse range of styles and generally appear in a linear, circular or cylindrical form, with slide rule scales inscribed with standardized Graduation (instrument), graduated markings. Slide rules manufactured for specialized fields such as aviation or finance typically feature additional scales that aid in specialized calculations particular to those fields. The slide rule is closely related to nomograms used for application-specific computations. Though similar in name and appearance to a standard ruler ...

Barrackpore
Barrackpore (also known as Barrackpur) is a city and a municipality of urban Kolkata of North 24 Parganas district in the Indian state of West Bengal. It is also a part of the area covered by Kolkata Metropolitan Development Authority (KMDA). It is the headquarters of the Barrackpore subdivision. Etymology The name Barrackpore may have originated from the English word barracks, as it was the site of the first cantonment of the British East India Company. Alternatively, the '' Ain-i-Akbari'' suggests that the name comes from "Barbakpur". ''Manasa Vijay'', written by Bipradas Pipilai, refers to Talpukur (a place in Barrackpore) as "Charnak". History The earliest references to the Barrackpore region are found in the writings of the Greek navigators, geographers, chronicles and historians of the 1st century BC to the 3rd century AD. These authors generally referred to the country of a people variously called the Gangaridai (also Gangaridae or Gandaritai). By the 15th and 1 ...

19th-century Irish Military Personnel
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 ...

People From Dungannon
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Dungannon
Dungannon () is a town in County Tyrone, Northern Ireland. It is the second-largest town in the county (after Omagh) and had a population of 14,340 at the 2011 Census. The Dungannon and South Tyrone Borough Council had its headquarters in the town, though since 2015 it has been covered by Mid-Ulster District Council. For centuries, it was the 'capital' of the O'Neill dynasty of Tír Eoghain, who dominated most of Ulster and built a castle on the hill. After the O'Neills' defeat in the Nine Years' War, the English founded a plantation town on the site, which grew into what is now Dungannon. Dungannon has won Ulster in Bloom's Best Kept Town Award five times. It currently has the highest percentage of immigrants of any town in Northern Ireland. History For centuries, Dungannon's fortunes were closely tied to that of the O'Neill dynasty which ruled a large part of Ulster until the 17th century. Dungannon was the clan's main stronghold. The traditional site of inauguration f ...
