Perturbation (astronomy)
In astronomy, perturbation is the complex motion of a astronomical object, massive body subjected to forces other than the gravity, gravitational attraction of a single other massive physical body, body. The other forces can include a third (fourth, fifth, etc.) body, drag (physics), resistance, as from an atmosphere, and the off-center attraction of an oblate spheroid, oblate or otherwise misshapen body. Introduction The study of perturbations began with the first attempts to predict planetary motions in the sky. In ancient times the causes were unknown. Isaac Newton, at the time he formulated his laws of Newton's laws of motion, motion and of Newton's law of universal gravitation, gravitation, applied them to the first analysis of perturbations, recognizing the complex difficulties of their calculation. Many of the great mathematicians since then have given attention to the various problems involved; throughout the 18th and 19th centuries there was demand for accurate tables o ...

Francis Baily
Francis Baily (28 April 177430 August 1844) was an English astronomer. He is most famous for his observations of "Baily's beads" during a total eclipse of the Sun. Baily was also a major figure in the early history of the Royal Astronomical Society, as one of the founders and as the president four times. Life Baily was born at Newbury in Berkshire in 1774 to Richard Baily. After a tour in the unsettled parts of North America in 1796–1797, his journal of which was edited by Augustus de Morgan in 1856, Baily entered the London Stock Exchange in 1799. The successive publication of ''Tables for the Purchasing and Renewing of Leases'' (1802), of ''The Doctrine of Interest and Annuities'' (1808), and ''The Doctrine of Life-Annuities and Assurances'' (1810), earned him a high reputation as a writer on life-contingencies; he amassed a fortune through diligence and integrity and retired from business in 1825, to devote himself wholly to astronomy.

Samuel Horsley
Samuel Horsley (15 September 1733 – 4 October 1806) was a British churchman, bishop of Rochester from 1793. He was also well versed in physics and mathematics, on which he wrote a number of papers and thus was elected a Fellow of the Royal Society in 1767; and secretary in 1773, but, in consequence of a difference with the president (Sir Joseph Banks) he withdrew in 1784. Life He was the son of Rev John Horsley of Newington Butts and his first wife Anne Hamilton, daughter of Rev Prof William Hamilton of Edinburgh and Mary Robertson. Entering Trinity Hall, Cambridge in 1751, he became LL.B. in 1758 without graduating in arts. In the following year he succeeded his father in the living of Newington Butts in Surrey. In 1768 he attended the son and heir of the 3rd Earl of Aylesford to Oxford as private tutor; and, after receiving through the earl and Bishop of London various minor preferments, which by dispensations he combined with his first living, he was installed in 1781 ...

British Critic
The ''British Critic: A New Review'' was a quarterly publication, established in 1793 as a conservative and high-church review journal riding the tide of British reaction against the French Revolution. The headquarters was in London. The journal ended publication in 1843. High-church review The Society for the Reformation of Principles, founded in 1792 by William Jones of Nayland and William Stevens, established the ''British Critic'' in 1793. Robert Nares and William Beloe, editor and assistant editor respectively, were joint proprietors with the booksellers and publishers Francis and Charles Rivington. It was started as a monthly, but in 1825 its frequency was shifted to quarterly. Nares and Beloe edited the review for about 20 years. Around 1811 the magazine was bought by Joshua Watson and Henry Handley Norris, associated with the high-church pressure group known as the Hackney Phalanx. After 1825 the review "became more narrowly theological in scope". Tractarian takeove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copley Medal
The Copley Medal is an award given by the Royal Society, for "outstanding achievements in research in any branch of science". It alternates between the physical sciences or mathematics and the biological sciences. Given every year, the medal is the oldest Royal Society medal awarded and the oldest surviving scientific award in the world, having first been given in 1731 to Stephen Gray (scientist), Stephen Gray, for "his new Electrical Experiments: – as an encouragement to him for the readiness he has always shown in obliging the Society with his discoveries and improvements in this part of Natural Knowledge". __TOC__ History The medal was created following a donation of Pound sterling, £100 to be used for carrying out experiments by Sir Godfrey Copley, 2nd Baronet, Sir Godfrey Copley, for which the interest on the amount was used for several years. The conditions for the medal have been changed several times; in 1736, it was suggested that "a medal or other honorary prize s ...

Philosophical Transactions
''Philosophical Transactions of the Royal Society'' is a scientific journal published by the Royal Society. In its earliest days, it was a private venture of the Royal Society's secretary. It was established in 1665, making it the first journal in the world exclusively devoted to science, and therefore also the world's longest-running scientific journal. It became an official society publication in 1752. The use of the word ''philosophical'' in the title refers to natural philosophy, which was the equivalent of what would now be generally called ''science''. Current publication In 1887 the journal expanded and divided into two separate publications, one serving the physical sciences ('' Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences'') and the other focusing on the life sciences ('' Philosophical Transactions of the Royal Society B: Biological Sciences''). Both journals now publish themed issues and issues resulting from pap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Windham
William Windham (4 June 1810) of Felbrigg Hall in Norfolk, was a British Whig statesman. Elected to Parliament in 1784, Windham was attached to the remnants of the Rockinghamite faction of Whigs, whose members included his friends Charles James Fox and Edmund Burke. Windham soon became noted for his oratory in the House of Commons. An early supporter of the French Revolution, by late 1791 he shared Burke's hostility to it and became a leading anti-Jacobin. After war was declared on France in early 1793, he broke with the anti-war, pro-Revolution Foxite Whigs to form a small 'Third Party' which was independent of Pitt's government but supportive of the war effort. Like Burke, Windham supported the war as an ideological crusade against Jacobinism and was an enthusiastic supporter of the French ''émigrés'' and a Bourbon restoration. In July 1794 he finally joined Pitt's government as Secretary at War but did not control war policy. He discovered that Pitt did not shar ...

Royal Observatory, Greenwich
The Royal Observatory, Greenwich (ROG; known as the Old Royal Observatory from 1957 to 1998, when the working Royal Greenwich Observatory, RGO, temporarily moved south from Greenwich to Herstmonceux) is an observatory situated on a hill in Greenwich Park in south east London, overlooking the River Thames to the north. It played a major role in the history of astronomy and navigation, and because the Prime Meridian passes through it, it gave its name to Greenwich Mean Time, the precursor to today's Coordinated Universal Time (UTC). The ROG has the IAU observatory code of 000, the first in the list. ROG, the National Maritime Museum, the Queen's House and the clipper ship ''Cutty Sark'' are collectively designated Royal Museums Greenwich. The observatory was commissioned in 1675 by King Charles II, with the foundation stone being laid on 10 August. The old hilltop site of Greenwich Castle was chosen by Sir Christopher Wren, a former Savilian Professor of Astronomy; as ...

HM Nautical Almanac Office
His Majesty's Nautical Almanac Office (HMNAO), now part of the United Kingdom Hydrographic Office, was established in 1832 on the site of the Royal Observatory, Greenwich (ROG), where ''The Nautical Almanac'' had been published since 1767. HMNAO produces astronomical data for a wide range of users, such as astronomers, mariners, aviators, surveyors, the military, Police, lawyers, religious groups, architects, schools, diary and calendar manufacturers, photographers and film crews. In 1937, it became part of ROG and moved with it, when it moved away from Greenwich (and was renamed the Royal Greenwich Observatory) first to Herstmonceux Castle, near Hailsham in East Sussex in 1948, then to Cambridge in 1990. When the RGO closed in 1998 HMNAO was transferred to the Rutherford Appleton Laboratory, near Abingdon in Oxfordshire. In December 2006, HMNAO was transferred to the United Kingdom Hydrographic Office, which is based in Taunton in Somerset. Leaders of HMNAO Superintendents of ...
