James Inman
James Inman (1776–1859), an English mathematician and astronomer, was professor of mathematics at the Royal Naval College, Portsmouth, and author of ''Inman's Nautical Tables''. Early years Inman was born at Tod Hole in Garsdale, then in the West Riding of Yorkshire, the younger son of Richard Inman and Jane Hutchinson. He was educated at Sedbergh and St John's College, Cambridge, graduating as first Smith's prizeman and Senior Wrangler for 1800. Among his close college friends was Henry Martyn. After graduating with first class honours in 1800, Inman intended to undertake missionary work in the Middle East, in Syria, but due to a declaration of war could travel no further than Malta, where he continued to study Arabic. Astronomer for Matthew Flinders, 1803–04 Returning to England, the Board of Longitude appointed him as replacement astronomer (the original astronomer, suffering from severe seasickness, was discharged en route to Australia) on the expedition of under ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational and theoretical. Observational astronomers make direct observations of celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate models of things that cannot be observed. Because it takes millions to billions of years for a system of stars or a galaxy to complete a life cycle, astronomers must observe sna ...

Warley (1796 Ship)
''Warley'', launched in 1796, was one of the British East India Company's (EIC), larger and more famous East Indiamen. She made nine voyages to the East between 1796 and 1816, most direct to China. In 1804 she participated in the Battle of Pulo Aura. In 1816, the company sold her for breaking up. Origins She was the second East Indiaman named ''Warley'' that John Perry built at his yard in Blackwall Yard. Perry built her predecessor in 1788; in 1795 the EIC sold the first of Perry's ''Warley''s to the Royal Navy, which renamed her . ''Warley's'' captain for her first five voyages was Henry Wilson, who had also been captain of the first ''Warley'' for her two voyages. Voyages 1, 2 and 3 ''Warley'' sailed under a letter of marque dated 1 January 1797, which named Wilson as the captain. Voyage 1 (1797–1798) Captain Henry Wilson sailed on 18 March 1797 from Portsmouth, bound for Bombay and China. ''Warley'' arrived at Bombay on 4 July and left on 1 October. She stopped at Tellic ...

All Saints' Church, Oakham
All Saints' Church, Oakham is a parish church in the Church of England in Oakham, Rutland. It is Grade I listed. History The spire of Oakham parish church dominates distant views of the town for several miles in all directions. The impressive west tower and spire, built during the 14th century in the Decorated Gothic style, are slightly earlier in date than most of the rest of the exterior of the building, which (apart from some Victorian restoration) is in the Perpendicular style. Oddly, the south doorway and its porch seem to be the oldest parts of the church, the doorway probably dating from the early 13th century with the porch having been added later that century. In the light, spacious interior there is more evidence of the mature Decorated style of the 14th century. The tall, slender columns of the nave have intricately carved capitals showing animals, birds, figures, foliage and scenes from the Bible including Adam and Eve, the Expulsion from the Garden of Eden, th ...

School Of Naval Architecture
A school is an educational institution designed to provide learning spaces and learning environments for the teaching of students under the direction of teachers. Most countries have systems of formal education, which is sometimes compulsory. In these systems, students progress through a series of schools. The names for these schools vary by country (discussed in the '' Regional terms'' section below) but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught is commonly called a university college or university. In addition to these core schools, students in a given country may also attend schools before and after primary (elementary in the U.S.) and secondary (middle school in the U.S.) education. Kindergarten or preschool provide some schooling to very young children (typically ages 3–5). University, vocational school, college or seminary may be ava ...

British Admiralty
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Gr ...

Haversine Formula
The haversine formula determines the great-circle distance between two points on a sphere given their longitudes and latitudes. Important in navigation, it is a special case of a more general formula in spherical trigonometry, the law of haversines, that relates the sides and angles of spherical triangles. The first table of haversines in English was published by James Andrew in 1805, but Florian Cajori credits an earlier use by José de Mendoza y Ríos in 1801. (NB. ISBN and link for reprint of second edition by Cosimo, Inc., New York, 2013.) The term '' haversine'' was coined in 1835 by James Inman. (Fourth edition) These names follow from the fact that they are customarily written in terms of the haversine function, given by . The formulas could equally be written in terms of any multiple of the haversine, such as the older versine function (twice the haversine). Prior to the advent of computers, the elimination of division and multiplication by factors of two proved convenie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spherical Trigonometry
Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the sides and angles of spherical triangles, traditionally expressed using trigonometric functions. On the sphere, geodesics are great circles. Spherical trigonometry is of great importance for calculations in astronomy, geodesy, and navigation. The origins of spherical trigonometry in Greek mathematics and the major developments in Islamic mathematics are discussed fully in History of trigonometry and Mathematics in medieval Islam. The subject came to fruition in Early Modern times with important developments by John Napier, Delambre and others, and attained an essentially complete form by the end of the nineteenth century with the publication of Todhunter's textbook ''Spherical trigonometry for the use of colleges and Schools''. Since then, significant developments have been the application of vector methods, quaternion methods, and the use of numerical methods. P ...

Haversine
The versine or versed sine is a trigonometric function found in some of the earliest (Sanskrit ''Aryabhatia'', Section I) trigonometric tables. The versine of an angle is 1 minus its cosine. There are several related functions, most notably the coversine and haversine. The latter, half a versine, is of particular importance in the of navigation.

Royal Naval College (Portsmouth)
The Royal Naval Academy was a facility established in 1733 in Portsmouth Dockyard to train officers for the Royal Navy. The founders' intentions were to provide an alternative means to recruit officers and to provide standardised training, education and admission. In 1806 it was renamed the Royal Naval College and in 1816 became the Royal Naval College and the School for Naval Architecture. It was closed as a training establishment for officer entrants in 1837. Training In 1733, a shoreside facility was established in the dockyard for 40 recruits. A comprehensive syllabus provided theoretical and practical experience in the dockyard and at sea. Graduates of the Academy could earn two years of sea time as part of their studies, and would be able to take the lieutenant's examination after four years at sea instead of six. The Academy did not, however, achieve the objective of becoming the preferred path to becoming a naval officer; the traditional means of a sea-going "apprentices ...
