Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics and chemistry in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, stars, nebulae and comets. More all phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject is physical cosmology, the study of the Universe as a whole. Astronomy is one of the oldest of the natural sciences; the early civilizations in recorded history, such as the Babylonians, Indians, Nubians, Chinese and many ancient indigenous peoples of the Americas, performed methodical observations of the night sky. Astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, the making of calendars, but professional astronomy is now considered to be synonymous with astrophysics. Professional astronomy is split into theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, analyzed using basic principles of physics.
Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain observational results and observations being used to confirm theoretical results. Astronomy is one of the few sciences in which amateurs still play an active role in the discovery and observation of transient events. Amateur astronomers have made and contributed to many important astronomical discoveries, such as finding new comets. Astronomy means "law of the stars". Astronomy should not be confused with astrology, the belief system which claims that human affairs are correlated with the positions of celestial objects. Although the two fields share a common origin, they are now distinct. Both of the terms "astronomy" and "astrophysics" may be used to refer to the same subject. Based on strict dictionary definitions, "astronomy" refers to "the study of objects and matter outside the Earth's atmosphere and of their physical and chemical properties," while "astrophysics" refers to the branch of astronomy dealing with "the behavior, physical properties, dynamic processes of celestial objects and phenomena."
In some cases, as in the introduction of the introductory textbook The Physical Universe by Frank Shu, "astronomy" may be used to describe the qualitative study of the subject, whereas "astrophysics" is used to describe the physics-oriented version of the subject. However, since most modern astronomical research deals with subjects related to physics, modern astronomy could be called astrophysics; some fields, such as astrometry, are purely astronomy rather than astrophysics. Various departments in which scientists carry out research on this subject may use "astronomy" and "astrophysics" depending on whether the department is affiliated with a physics department, many professional astronomers have physics rather than astronomy degrees; some titles of the leading scientific journals in this field include The Astronomical Journal, The Astrophysical Journal, Astronomy and Astrophysics. In early historic times, astronomy only consisted of the observation and predictions of the motions of objects visible to the naked eye.
In some locations, early cultures assembled massive artifacts that had some astronomical purpose. In addition to their ceremonial uses, these observatories could be employed to determine the seasons, an important factor in knowing when to plant crops and in understanding the length of the year. Before tools such as the telescope were invented, early study of the stars was conducted using the naked eye; as civilizations developed, most notably in Mesopotamia, Persia, China and Central America, astronomical observatories were assembled and ideas on the nature of the Universe began to develop. Most early astronomy consisted of mapping the positions of the stars and planets, a science now referred to as astrometry. From these observations, early ideas about the motions of the planets were formed, the nature of the Sun and the Earth in the Universe were explored philosophically; the Earth was believed to be the center of the Universe with the Sun, the Moon and the stars rotating around it. This is known as the geocentric model of the Ptolemaic system, named after Ptolemy.
A important early development was the beginning of mathematical and scientific astronomy, which began among the Babylonians, who laid the foundations for the astronomical traditions that developed in many other civilizations. The Babylonians discovered. Following the Babylonians, significant advances in astronomy were made in ancient Greece and the Hellenistic world. Greek astronomy is characterized from the start by seeking a rational, physical explanation for celestial phenomena. In the 3rd century BC, Aristarchus of Samos estimated the size and distance of the Moon and Sun, he proposed a model of the Solar System where the Earth and planets rotated around the Sun, now called the heliocentric model. In the 2nd century BC, Hipparchus discovered precession, calculated the size and distance of the Moon and inven
Lockyer (Martian crater)
Lockyer is a crater in the Elysium quadrangle of Mars, located at 28° North and 199.5° West. It was named after Norman Lockyer, a British astronomer. Lockyer is easy to spot on Mars maps because it sits in the young northern hemisphere, where there are few craters, it is close to Hecates Tholus, two large volcanoes. Impact craters have a rim with ejecta around them, in contrast volcanic craters do not have a rim or ejecta deposits; as craters get larger they have a central peak. The peak is caused by a rebound of the crater floor following the impact. List of craters on Mars
Fellow of the Royal Society
Fellowship of the Royal Society is an award granted to individuals that the Royal Society of London judges to have made a'substantial contribution to the improvement of natural knowledge, including mathematics, engineering science and medical science'. Fellowship of the Society, the oldest scientific academy in continuous existence, is a significant honour, awarded to many eminent scientists from history including Isaac Newton, Charles Darwin, Michael Faraday, Ernest Rutherford, Srinivasa Ramanujan, Albert Einstein, Winston Churchill, Subrahmanyan Chandrasekhar, Dorothy Hodgkin, Alan Turing and Francis Crick. More fellowship has been awarded to Stephen Hawking, Tim Hunt, Elizabeth Blackburn, Tim Berners-Lee, Venkatraman Ramakrishnan, Atta-ur Rahman, Andre Geim, James Dyson, Ajay Kumar Sood, Subhash Khot, Elon Musk and around 8,000 others in total, including over 280 Nobel Laureates since 1900; as of October 2018, there are 1689 living Fellows and Honorary Members, of which over 60 are Nobel Laureates.
Fellowship of the Royal Society has been described by The Guardian newspaper as “the equivalent of a lifetime achievement Oscar” with several institutions celebrating their announcement each year. Up to 60 new Fellows and foreign members are elected annually in late April or early May, from a pool of around 700 proposed candidates each year. New Fellows can only be nominated by existing Fellows for one of the fellowships described below: Every year, up to 52 new Fellows are elected from the United Kingdom and the Commonwealth of Nations which make up around 90% of the society; each candidate is considered on their merits and can be proposed from any sector of the scientific community. Fellows are elected for life on the basis of excellence in science and are entitled to use the post-nominal letters FRS. See Category:Fellows of the Royal Society and Category:Female Fellows of the Royal Society; every year, Fellows elect up to ten new Foreign Members. Like Fellows, Foreign Members are elected for life through peer review on the basis of excellence in science.
As of 2016 there are around 165 Foreign Members, who are entitled to use the post-nominal ForMemRS. See Category:Foreign Members of the Royal Society. Honorary Fellowship is an honorary academic title awarded to candidates who have given distinguished service to the cause of science, but do not have the kind of scientific achievements required of Fellows or Foreign Members. Honorary Fellows include Bill Bryson, Melvyn Bragg, Robin Saxby, David Sainsbury, Baron Sainsbury of Turville and Onora O'Neill. Honorary Fellows are entitled to use the post nominal letters FRS. Others including John Maddox, Patrick Moore and Lisa Jardine were elected as honorary fellows, see Category:Honorary Fellows of the Royal Society. Statute 12 is a legacy mechanism for electing members before official honorary membership existed in 1997. Fellows elected under statute 12 include 4th Earl of Selborne. Prime Ministers of the United Kingdom such as Margaret Thatcher, Neville Chamberlain,Ramsay Macdonald and H. H. Asquith were elected under statute 12, see Category:Fellows of the Royal Society.
The Council of the Royal Society can recommend members of the British Royal Family for election as Royal Fellows of the Royal Society. As of 2016 there are five royal fellows: Charles, Prince of Wales elected 1978 Anne, Princess Royal elected 1987 Prince Edward, Duke of Kent elected 1990 Prince William, Duke of Cambridge elected 2009 Prince Andrew, Duke of York elected 2013Her Majesty the Queen, Elizabeth II is not a Royal Fellow, but provides her patronage to the Society as all reigning British monarchs have done since Charles II of England. Prince Philip, Duke of Edinburgh was elected under statute 12, not as a Royal Fellow; the election of new fellows is announced annually in May, after their nomination and a period of peer-reviewed selection. Each candidate for Fellowship or Foreign Membership is nominated by two Fellows of the Royal Society, who sign a certificate of proposal. Nominations required at least five fellows to support each nomination by the proposer, criticised for establishing an old-boy network and elitist gentlemen's club.
The certificate of election includes a statement of the principal grounds on which the proposal is being made. There is no limit on the number of nominations made each year. In 2015, there were 654 candidates for election as Fellows and 106 candidates for Foreign Membership; the Council of the Royal Society oversees the selection process and appoints 10 subject area committees, known as Sectional Committees, to recommend the strongest candidates for election to Fellowship. The final list of up to 52 Fellowship candidates and up to 10 Foreign Membership candidates is confirmed by the Council in April and a secret ballot of Fellows is held at a meeting in May. A candidate is elected if she secures two-thirds of votes of those Fellows present and voting. A maximum of 18 Fellowships can be allocated to candidates from Physical Sciences and Biological Sciences. A further maximum of 6 can be ‘Honorary’, ‘General’ or ‘Royal’ Fellows. Nominations for Fellowship are peer reviewed by sectional committees, each with 15 members and a chair.
Members of the 10 sectional committees change every 3 years to mitigate in-group bias, each group covers different
Devon known as Devonshire, its common and official name, is a county of England, reaching from the Bristol Channel in the north to the English Channel in the south. It is part of South West England, bounded by Cornwall to the west, Somerset to the north east, Dorset to the east; the city of Exeter is the county town. The county includes the districts of East Devon, Mid Devon, North Devon, South Hams, Teignbridge and West Devon. Plymouth and Torbay are each geographically part of Devon, but are administered as unitary authorities. Combined as a ceremonial county, Devon's area is 6,707 km2 and its population is about 1.1 million. Devon derives its name from Dumnonia. During the British Iron Age, Roman Britain, the early Middle Ages, this was the homeland of the Dumnonii Brittonic Celts; the Anglo-Saxon settlement of Britain resulted in the partial assimilation of Dumnonia into the Kingdom of Wessex during the eighth and ninth centuries. The western boundary with Cornwall was set at the River Tamar by King Æthelstan in 936.
Devon was constituted as a shire of the Kingdom of England. The north and south coasts of Devon each have both cliffs and sandy shores, the county's bays contain seaside resorts, fishing towns, ports; the inland terrain is rural and hilly, has a lower population density than many other parts of England. Dartmoor is the largest open space in southern England, at 954 km2. To the north of Dartmoor are the Culm Measures and Exmoor. In the valleys and lowlands of south and east Devon the soil is more fertile, drained by rivers including the Exe, the Culm, the Teign, the Dart, the Otter; as well as agriculture, much of the economy of Devon is based on tourism. The comparatively mild climate and landscape make Devon a destination for recreation and leisure in England, with visitors attracted to the Dartmoor and Exmoor national parks; the name Devon derives from the name of the Britons who inhabited the southwestern peninsula of Britain at the time of the Roman conquest of Britain known as the Dumnonii, thought to mean "deep valley dwellers" from proto Celtic *dubnos'deep'.
In the Brittonic, Devon is known as Welsh: Dyfnaint, Breton: Devnent and Cornish: Dewnens, each meaning "deep valleys." Among the most common Devon placenames is -combe which derives from Brittonic cwm meaning'valley' prefixed by the name of the possessor. William Camden, in his 1607 edition of Britannia, described Devon as being one part of an older, wider country that once included Cornwall: THAT region which, according to the Geographers, is the first of all Britaine, growing straiter still and narrower, shooteth out farthest into the West, was in antient time inhabited by those Britans whom Solinus called Dumnonii, Ptolomee Damnonii For their habitation all over this Countrey is somewhat low and in valleys, which manner of dwelling is called in the British tongue Dan-munith, in which sense the Province next adjoyning in like respect is at this day named by the Britans Duffneit, to say, Low valleys, but the Country of this nation is at this day divided into two parts, knowen by names of Cornwall and Denshire, The term "Devon" is used for everyday purposes e.g. "Devon County Council" but "Devonshire" continues to be used in the names of the "Devonshire and Dorset Regiment" and "The Devonshire Association".
One erroneous theory is that the "shire" suffix is due to a mistake in the making of the original letters patent for the Duke of Devonshire, resident in Derbyshire. However, there are references to "Defenascire" in Anglo-Saxon texts from before 1000 AD, which translates to modern English as "Devonshire"; the term Devonshire may have originated around the 8th century, when it changed from Dumnonia to Defenascir. Kents Cavern in Torquay had produced. Dartmoor is thought to have been occupied by Mesolithic hunter-gatherer peoples from about 6000 BC; the Romans held the area under military occupation for around 350 years. The area began to experience Saxon incursions from the east around 600 AD, firstly as small bands of settlers along the coasts of Lyme Bay and southern estuaries and as more organised bands pushing in from the east. Devon became a frontier between Brittonic and Anglo-Saxon Wessex, it was absorbed into Wessex by the mid 9th century. A genetic study carried out by the University of Oxford & University College London discovered separate genetic groups in Cornwall and Devon, not only were there differences on either side of the Tamar, with a division exactly along the modern county boundary dating back to the 6th Century but between Devon and the rest of Southern England, similarities with the modern northern France, including Brittany.
This suggests the Anglo-Saxon migration into Devon was limited rather than a mass movement of people. The border with Cornwall was set by King Æthelstan on the east bank of the River Tamar in 936 AD. Danish raids occurred sporadically along many coastal parts of Devon between around 800AD and just before the time of the Norman conquest, including the silver mint at Hlidaforda Lydford in 997 and Taintona in 1001. Devon has featured in most of th
Nature is a British multidisciplinary scientific journal, first published on 4 November 1869. It is one of the most recognizable scientific journals in the world, was ranked the world's most cited scientific journal by the Science Edition of the 2010 Journal Citation Reports and is ascribed an impact factor of 40.137, making it one of the world's top academic journals. It is one of the few remaining academic journals that publishes original research across a wide range of scientific fields. Research scientists are the primary audience for the journal, but summaries and accompanying articles are intended to make many of the most important papers understandable to scientists in other fields and the educated public. Towards the front of each issue are editorials and feature articles on issues of general interest to scientists, including current affairs, science funding, scientific ethics and research breakthroughs. There are sections on books and short science fiction stories; the remainder of the journal consists of research papers, which are dense and technical.
Because of strict limits on the length of papers the printed text is a summary of the work in question with many details relegated to accompanying supplementary material on the journal's website. There are many fields of research in which important new advances and original research are published as either articles or letters in Nature; the papers that have been published in this journal are internationally acclaimed for maintaining high research standards. Fewer than 8% of submitted papers are accepted for publication. In 2007 Nature received the Prince of Asturias Award for Humanity; the enormous progress in science and mathematics during the 19th century was recorded in journals written in German or French, as well as in English. Britain underwent enormous technological and industrial changes and advances in the latter half of the 19th century. In English the most respected scientific journals of this time were the refereed journals of the Royal Society, which had published many of the great works from Isaac Newton, Michael Faraday through to early works from Charles Darwin.
In addition, during this period, the number of popular science periodicals doubled from the 1850s to the 1860s. According to the editors of these popular science magazines, the publications were designed to serve as "organs of science", in essence, a means of connecting the public to the scientific world. Nature, first created in 1869, was not the first magazine of its kind in Britain. One journal to precede Nature was Recreative Science: A Record and Remembrancer of Intellectual Observation, created in 1859, began as a natural history magazine and progressed to include more physical observational science and technical subjects and less natural history; the journal's name changed from its original title to Intellectual Observer: A Review of Natural History, Microscopic Research, Recreative Science and later to the Student and Intellectual Observer of Science and Art. While Recreative Science had attempted to include more physical sciences such as astronomy and archaeology, the Intellectual Observer broadened itself further to include literature and art as well.
Similar to Recreative Science was the scientific journal Popular Science Review, created in 1862, which covered different fields of science by creating subsections titled "Scientific Summary" or "Quarterly Retrospect", with book reviews and commentary on the latest scientific works and publications. Two other journals produced in England prior to the development of Nature were the Quarterly Journal of Science and Scientific Opinion, established in 1864 and 1868, respectively; the journal most related to Nature in its editorship and format was The Reader, created in 1864. These similar journals all failed; the Popular Science Review survived longest, lasting 20 years and ending its publication in 1881. The Quarterly Journal, after undergoing a number of editorial changes, ceased publication in 1885; the Reader terminated in 1867, Scientific Opinion lasted a mere 2 years, until June 1870. Not long after the conclusion of The Reader, a former editor, Norman Lockyer, decided to create a new scientific journal titled Nature, taking its name from a line by William Wordsworth: "To the solid ground of nature trusts the Mind that builds for aye".
First owned and published by Alexander Macmillan, Nature was similar to its predecessors in its attempt to "provide cultivated readers with an accessible forum for reading about advances in scientific knowledge." Janet Browne has proposed that "far more than any other science journal of the period, Nature was conceived and raised to serve polemic purpose." Many of the early editions of Nature consisted of articles written by members of a group that called itself the X Club, a group of scientists known for having liberal and somewhat controversial scientific beliefs relative to the time period. Initiated by Thomas Henry Huxley, the group consisted of such important scientists as Joseph Dalton Hooker, Herbert Spencer, John Tyndall, along with another five scientists and mathematicians, it was in part its scientific liberality that made Nature a longer-lasti
Wimbledon is a district and town of south-west London, England, 7.1 miles south-west of the centre of London at Charing Cross, in the London Borough of Merton, south of Wandsworth, north-east of New Malden, north-west of Mitcham, west of Streatham and north of Sutton. Wimbledon had a population of 68,187 in 2011 which includes the electoral wards of Abbey, Hillside, Village, Raynes Park and Wimbledon Park, it is home to the Wimbledon Tennis Championships and New Wimbledon Theatre, contains Wimbledon Common, one of the largest areas of common land in London along with a Wimbledon Tennis Club. The residential and retail area is split into two sections known as the "village" and the "town", with the High Street being the rebuilding of the original medieval village, the "town" having first developed after the building of the railway station in 1838. Wimbledon has been inhabited since at least the Iron Age when the hill fort on Wimbledon Common is thought to have been constructed. In 1087 when the Domesday Book was compiled, Wimbledon was part of the manor of Mortlake.
The ownership of the manor of Wimbledon changed between various wealthy families many times during its history, the area attracted other wealthy families who built large houses such as Eagle House, Wimbledon Manor House and Warren House. The village developed with a stable rural population coexisting with nobility and wealthy merchants from the city. In the 18th century the Dog and Fox public house became a stop on the stagecoach run from London to Portsmouth in 1838 the London and South Western Railway opened a station to the south-east of the village at the bottom of Wimbledon Hill; the location of the station shifted the focus of the town's subsequent growth away from the original village centre. Wimbledon had its own borough larger than its historic boundaries while still in the county of Surrey. Since 2005, the north and west of the borough have been represented in Westminster by Stephen Hammond, a Conservative MP; the east and south of the Borough are represented by Siobhain McDonagh, a Labour MP.
Wimbledon has established minority groups. Wimbledon, a small farming locality in New Zealand, was named after this district in the 1880s after a local resident shot a bullock from a considerable distance away; the shot was considered by onlookers to be worthy of the rifle-shooting championships held in Wimbledon at the time. Wimbledon has been inhabited since at least the Iron Age when the hill fort on Wimbledon Common, the second-largest in London, is thought to have been constructed; the original nucleus of Wimbledon was at the top of the hill close to the common – the area now known locally as "the village". The village is referred to as "Wimbedounyng" in a charter signed by King Edgar the Peaceful in 967; the name Wimbledon means "Wynnman's hill", with the final element of the name being the Celtic "dun". The name is shown on J. Cary's 1786 map of the London area as "Wimbleton", the current spelling appears to have been settled on recently in the early 19th century, the last in a long line of variations.
At the time the Domesday Book was compiled, Wimbledon was part of the manor of Mortlake, so was not recorded. The ownership of the manor of Wimbledon changed hands many times during its history; the manor was held by the church until 1398 when Thomas Arundel, Archbishop of Canterbury fell out of favour with Richard II and was exiled. The manor became crown property; the manor remained crown property until the reign of Henry VIII when it was granted to Thomas Cromwell, Earl of Essex, until Cromwell was executed in 1540 and the land was again confiscated. The manor was next held by Henry VIII's last wife and widow Catherine Parr until her death in 1548 when it again reverted to the monarch. In the 1550s, Henry's daughter, Mary I, granted the manor to Cardinal Reginald Pole who held it until his death in 1558 when it once again become royal property. Mary's sister, Elizabeth I held the property until 1574, when she gave the manor house to Christopher Hatton, who sold it in the same year to Sir Thomas Cecil, Earl of Exeter.
The lands of the manor were given to the Cecil family in 1588 and a new manor house, Wimbledon Palace, was constructed and gardens laid out in the formal Elizabethan style. Wimbledon's proximity to the capital was beginning to attract other wealthy families. In 1613 Robert Bell, Master of the Worshipful Company of Girdlers and a director of the British East India Company built Eagle House as a home at an easy distance from London; the Cecil family retained the manor for fifty years, before it was bought by Charles I in 1638 for his Queen, Henrietta Maria. Following the King's execution in 1649, the manor passed among various parliamentarian owners, including the Leeds MP Adam Baynes and the civil war general John Lambert, but after the restoration of the monarchy in 1660, it was returned to Henrietta Maria; the Dowager Queen sold the manor in 1661 to George Digby, Earl of Bristol, who employed John Evelyn to improve and update the landscape in accordance with the latest fashions, including grottos and fountains.
On his death in 1677, the manor was sold again to the Lord High Treasurer, Thomas Osborne, Earl of Danby. The Osborne family sold the manor to Sir Theodore Janssen in 1712. Janssen, a director of the South Sea Company, began a new house to replace the one built by the Cecils, but the spectacular collapse of the company meant it was never finished; the next owner was Sarah Church
