Astronomy
–
Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets, while the phenomena include supernovae explosions, gamma ray bursts, more generally, all astronomical phenomena that originate outside Earths atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole, Astronomy is the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, during the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, 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 the results and observations being used to confirm theoretical results. Astronomy is one of the few sciences where amateurs can play an active role, especially in the discovery. Amateur astronomers have made and contributed to many important astronomical discoveries, Astronomy means law of the stars. Astronomy should not be confused with astrology, the system which claims that human affairs are correlated with the positions of celestial objects. Although the two share a common origin, they are now entirely distinct. Generally, either the term astronomy or astrophysics may be used to refer to this subject, however, since most modern astronomical research deals with subjects related to physics, modern astronomy could actually be called astrophysics. Few fields, such as astrometry, are purely astronomy rather than also astrophysics, some titles of the leading scientific journals in this field includeThe Astronomical Journal, The Astrophysical Journal and Astronomy and Astrophysics. In early times, astronomy only comprised the observation and predictions of the motions of objects visible to the naked eye, in some locations, early cultures assembled massive artifacts that possibly had some astronomical purpose. Before tools such as the telescope were invented, early study of the stars was conducted using the naked eye, most of early astronomy actually 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, and the nature of the Sun, Moon, 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 model of the Universe, or the Ptolemaic system. The Babylonians discovered that lunar eclipses recurred in a cycle known as a saros

Astrophysics
–
Astrophysics is the branch of astronomy that employs the principles of physics and chemistry to ascertain the nature of the heavenly bodies, rather than their positions or motions in space. Among the objects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and their emissions are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. In practice, modern astronomical research often involves an amount of work in the realms of theoretical and observational physics. Although astronomy is as ancient as recorded history itself, it was separated from the study of terrestrial physics. Their challenge was that the tools had not yet been invented with which to prove these assertions, for much of the nineteenth century, astronomical research was focused on the routine work of measuring the positions and computing the motions of astronomical objects. Kirchhoff deduced that the lines in the solar spectrum are caused by absorption by chemical elements in the Solar atmosphere. In this way it was proved that the elements found in the Sun. Among those who extended the study of solar and stellar spectra was Norman Lockyer and he thus claimed the line represented a new element, which was called helium, after the Greek Helios, the Sun personified. By 1890, a catalog of over 10,000 stars had been prepared that grouped them into thirteen spectral types, most significantly, she discovered that hydrogen and helium were the principal components of stars. This discovery was so unexpected that her dissertation readers convinced her to modify the conclusion before publication, however, later research confirmed her discovery. By the end of the 20th century, studies of astronomical spectra had expanded to cover wavelengths extending from radio waves through optical, x-ray and it is the practice of observing celestial objects by using telescopes and other astronomical apparatus. The majority of observations are made using the electromagnetic spectrum. Radio astronomy studies radiation with a greater than a few millimeters. The study of these waves requires very large radio telescopes, infrared astronomy studies radiation with a wavelength that is too long to be visible to the naked eye but is shorter than radio waves. Infrared observations are made with telescopes similar to the familiar optical telescopes. Objects colder than stars are studied at infrared frequencies. Optical astronomy is the oldest kind of astronomy, telescopes paired with a charge-coupled device or spectroscopes are the most common instruments used. The Earths atmosphere interferes somewhat with optical observations, so adaptive optics, in this wavelength range, stars are highly visible, and many chemical spectra can be observed to study the chemical composition of stars, galaxies and nebulae

Oxford University Press
–
Oxford University Press is the largest university press in the world, and the second oldest after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics appointed by the known as the delegates of the press. They are headed by the secretary to the delegates, who serves as OUPs chief executive, Oxford University has used a similar system to oversee OUP since the 17th century. The university became involved in the print trade around 1480, and grew into a printer of Bibles, prayer books. OUP took on the project became the Oxford English Dictionary in the late 19th century. Moves into international markets led to OUP opening its own offices outside the United Kingdom, by contracting out its printing and binding operations, the modern OUP publishes some 6,000 new titles around the world each year. OUP was first exempted from United States corporation tax in 1972, as a department of a charity, OUP is exempt from income tax and corporate tax in most countries, but may pay sales and other commercial taxes on its products. The OUP today transfers 30% of its surplus to the rest of the university. OUP is the largest university press in the world by the number of publications, publishing more than 6,000 new books every year, the Oxford University Press Museum is located on Great Clarendon Street, Oxford. Visits must be booked in advance and are led by a member of the archive staff, displays include a 19th-century printing press, the OUP buildings, and the printing and history of the Oxford Almanack, Alice in Wonderland and the Oxford English Dictionary. The first printer associated with Oxford University was Theoderic Rood, the first book printed in Oxford, in 1478, an edition of Rufinuss Expositio in symbolum apostolorum, was printed by another, anonymous, printer. Famously, this was mis-dated in Roman numerals as 1468, thus apparently pre-dating Caxton, roods printing included John Ankywylls Compendium totius grammaticae, which set new standards for teaching of Latin grammar. After Rood, printing connected with the university remained sporadic for over half a century, the chancellor, Robert Dudley, 1st Earl of Leicester, pleaded Oxfords case. Some royal assent was obtained, since the printer Joseph Barnes began work, Oxfords chancellor, Archbishop William Laud, consolidated the legal status of the universitys printing in the 1630s. Laud envisaged a unified press of world repute, Oxford would establish it on university property, govern its operations, employ its staff, determine its printed work, and benefit from its proceeds. To that end, he petitioned Charles I for rights that would enable Oxford to compete with the Stationers Company and the Kings Printer and these were brought together in Oxfords Great Charter in 1636, which gave the university the right to print all manner of books. Laud also obtained the privilege from the Crown of printing the King James or Authorized Version of Scripture at Oxford and this privilege created substantial returns in the next 250 years, although initially it was held in abeyance. The Stationers Company was deeply alarmed by the threat to its trade, under this, the Stationers paid an annual rent for the university not to exercise its full printing rights – money Oxford used to purchase new printing equipment for smaller purposes

Royal Astronomical Society
–
The Royal Astronomical Society is a learned society that began as the Astronomical Society of London in 1820 to support astronomical research. It became the Royal Astronomical Society in 1831 on receiving its Royal Charter from William IV, a Supplemental Charter in 1915 opened up the fellowship to women. Meetings are held in Burlington House, in Piccadilly, London and they are involved in the production of astronomical journals and periodicals. The society has over 3000 members, around a third of whom live outside the UK, in addition, those members of the public who have an interest in astronomy and geophysics and wish to support the work of the society may become Friends of the RAS. One of the activities of the RAS is publishing refereed journals. It publishes two primary research journals, the Monthly Notices of the Royal Astronomical Society in astronomy and the Geophysical Journal International in geophysics and it also publishes the magazine A&G which includes reviews and other articles of wide scientific interest in a glossy format. Fellowship is open to anyone over the age of 18 who is considered acceptable to the society, as a result of the societys foundation in a time before there were many professional astronomers, no formal qualifications are required. However, around three quarters of fellows are professional astronomers or geophysicists, the society acts as the professional body for astronomers and geophysicists in the UK and fellows may apply for the Science Councils Chartered Scientist status through the society. The fellowship passed 3,000 in 2003, in 2009 an initiative was launched for those with an interest in astronomy and geophysics but without professional qualifications or specialist knowledge in the subject. Such people may join the Friends of the RAS, which offers popular talks, visits, ordinary meetings featuring lectures about research topics in astronomy and geophysics are normally held in Burlington House in London on the second Friday of every month from October through to May. Reports of the meetings appear in The Observatory magazine, scientific discussion meetings about particular research topics are held on the day of the ordinary meetings. These allow several speakers to present new research results and experts to present reviews of scientific fields, discussion meetings on two different topics within astronomy and geophysics frequently take place in parallel at different locations within Burlington House. The Society occasionally hosts meetings in other parts of the United Kingdom, the Society also sponsors the National Astronomy Meeting, a week-long general conference of professional astronomers, normally held each spring at a university campus in the United Kingdom. The Society holds occasional lunchtime public lectures in Central London aimed at a general, non-specialist, the Royal Astronomical Society has a more comprehensive collection of books and journals in astronomy and geophysics than the libraries of most universities and research institutions. The library receives some 300 current periodicals in astronomy and geophysics and its collection of astronomical rare books is second only to that of the Royal Observatory in Edinburgh in the UK. The RAS library is a resource not just for the society but also the wider community of astronomers, geophysicists. The society promotes astronomy to members of the public through their outreach pages for students, teachers. The RAS has a role in relation to UK public examinations, such as GCSEs

United Kingdom
–
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, the United Kingdom includes the island of Great Britain, Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. The Irish Sea lies between Great Britain and Ireland, with an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants, together, this makes it the fourth-most densely populated country in the European Union. The United Kingdom is a monarchy with a parliamentary system of governance. The monarch is Queen Elizabeth II, who has reigned since 6 February 1952, other major urban areas in the United Kingdom include the regions of Birmingham, Leeds, Glasgow, Liverpool and Manchester. The United Kingdom consists of four countries—England, Scotland, Wales, the last three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff and Belfast, respectively. The relationships among the countries of the UK have changed over time, Wales was annexed by the Kingdom of England under the Laws in Wales Acts 1535 and 1542. A treaty between England and Scotland resulted in 1707 in a unified Kingdom of Great Britain, which merged in 1801 with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain, there are fourteen British Overseas Territories. These are the remnants of the British Empire which, at its height in the 1920s, British influence can be observed in the language, culture and legal systems of many of its former colonies. The United Kingdom is a country and has the worlds fifth-largest economy by nominal GDP. The UK is considered to have an economy and is categorised as very high in the Human Development Index. It was the worlds first industrialised country and the worlds foremost power during the 19th, the UK remains a great power with considerable economic, cultural, military, scientific and political influence internationally. It is a nuclear weapons state and its military expenditure ranks fourth or fifth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946 and it has been a leading member state of the EU and its predecessor, the European Economic Community, since 1973. However, on 23 June 2016, a referendum on the UKs membership of the EU resulted in a decision to leave. The Acts of Union 1800 united the Kingdom of Great Britain, Scotland, Wales and Northern Ireland have devolved self-government

The United States National Library of Medicine, operated by the United States federal government, is the worlds largest medical library. Located in Bethesda, Maryland, the NLM is an institute within the National Institutes of Health, the current director of the NLM is Patricia Flatley Brennan. Since 1879, the National Library of Medicine has published the Index Medicus and these resources are accessible without charge on the internet. S. and international consultants. The Extramural Division provides grants to research in medical information science and to support planning and development of computer. Research, publications, and exhibitions on the history of medicine, in April 2008 the current exhibition Against the Odds, Making a Difference in Global Health was launched. For details of the history of the Library, see Library of the Surgeon Generals Office. The precursor of the National Library of Medicine, established in 1836, was the Library of the Surgeon Generals Office, the Armed Forces Institute of Pathology and its Medical Museum were founded in 1862 as the Army Medical Museum. Throughout their history the Library of the Surgeon Generals Office and the Army Medical Museum often shared quarters, from 1866 to 1887, they were housed in Fords Theatre after production there was stopped, following the assassination of President Abraham Lincoln.

International Standard Serial Number
–
An International Standard Serial Number is an eight-digit serial number used to uniquely identify a serial publication. The ISSN is especially helpful in distinguishing between serials with the same title, ISSN are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature. The ISSN system was first drafted as an International Organization for Standardization international standard in 1971, ISO subcommittee TC 46/SC9 is responsible for maintaining the standard. When a serial with the content is published in more than one media type. For example, many serials are published both in print and electronic media, the ISSN system refers to these types as print ISSN and electronic ISSN, respectively. The format of the ISSN is an eight digit code, divided by a hyphen into two four-digit numbers, as an integer number, it can be represented by the first seven digits. The last code digit, which may be 0-9 or an X, is a check digit. Formally, the form of the ISSN code can be expressed as follows, NNNN-NNNC where N is in the set, a digit character. The ISSN of the journal Hearing Research, for example, is 0378-5955, where the final 5 is the check digit, for calculations, an upper case X in the check digit position indicates a check digit of 10. To confirm the check digit, calculate the sum of all eight digits of the ISSN multiplied by its position in the number, the modulus 11 of the sum must be 0. There is an online ISSN checker that can validate an ISSN, ISSN codes are assigned by a network of ISSN National Centres, usually located at national libraries and coordinated by the ISSN International Centre based in Paris. The International Centre is an organization created in 1974 through an agreement between UNESCO and the French government. The International Centre maintains a database of all ISSNs assigned worldwide, at the end of 2016, the ISSN Register contained records for 1,943,572 items. ISSN and ISBN codes are similar in concept, where ISBNs are assigned to individual books, an ISBN might be assigned for particular issues of a serial, in addition to the ISSN code for the serial as a whole. An ISSN, unlike the ISBN code, is an identifier associated with a serial title. For this reason a new ISSN is assigned to a serial each time it undergoes a major title change, separate ISSNs are needed for serials in different media. Thus, the print and electronic versions of a serial need separate ISSNs. Also, a CD-ROM version and a web version of a serial require different ISSNs since two different media are involved, however, the same ISSN can be used for different file formats of the same online serial

OCLC
–
The Online Computer Library Center is a US-based nonprofit cooperative organization dedicated to the public purposes of furthering access to the worlds information and reducing information costs. It was founded in 1967 as the Ohio College Library Center, OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog in the world. OCLC is funded mainly by the fees that libraries have to pay for its services, the group first met on July 5,1967 on the campus of the Ohio State University to sign the articles of incorporation for the nonprofit organization. The group hired Frederick G. Kilgour, a former Yale University medical school librarian, Kilgour wished to merge the latest information storage and retrieval system of the time, the computer, with the oldest, the library. The goal of network and database was to bring libraries together to cooperatively keep track of the worlds information in order to best serve researchers and scholars. The first library to do online cataloging through OCLC was the Alden Library at Ohio University on August 26,1971 and this was the first occurrence of online cataloging by any library worldwide. Membership in OCLC is based on use of services and contribution of data, between 1967 and 1977, OCLC membership was limited to institutions in Ohio, but in 1978, a new governance structure was established that allowed institutions from other states to join. In 2002, the structure was again modified to accommodate participation from outside the United States. As OCLC expanded services in the United States outside of Ohio, it relied on establishing strategic partnerships with networks, organizations that provided training, support, by 2008, there were 15 independent United States regional service providers. OCLC networks played a key role in OCLC governance, with networks electing delegates to serve on OCLC Members Council, in early 2009, OCLC negotiated new contracts with the former networks and opened a centralized support center. OCLC provides bibliographic, abstract and full-text information to anyone, OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog in the world. WorldCat has holding records from public and private libraries worldwide. org, in October 2005, the OCLC technical staff began a wiki project, WikiD, allowing readers to add commentary and structured-field information associated with any WorldCat record. The Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988, a browser for books with their Dewey Decimal Classifications was available until July 2013, it was replaced by the Classify Service. S. The reference management service QuestionPoint provides libraries with tools to communicate with users and this around-the-clock reference service is provided by a cooperative of participating global libraries. OCLC has produced cards for members since 1971 with its shared online catalog. OCLC commercially sells software, e. g. CONTENTdm for managing digital collections, OCLC has been conducting research for the library community for more than 30 years. In accordance with its mission, OCLC makes its research outcomes known through various publications and these publications, including journal articles, reports, newsletters, and presentations, are available through the organizations website. The most recent publications are displayed first, and all archived resources, membership Reports – A number of significant reports on topics ranging from virtual reference in libraries to perceptions about library funding

Peer review
–
Peer review is the evaluation of work by one or more people of similar competence to the producers of the work. It constitutes a form of self-regulation by qualified members of a profession within the relevant field, peer review methods are employed to maintain standards of quality, improve performance, and provide credibility. In academia, scholarly peer review is used to determine an academic papers suitability for publication. Peer review can be categorized by the type of activity and by the field or profession in which the activity occurs, professional peer review focuses on the performance of professionals, with a view to improving quality, upholding standards, or providing certification. In academia, peer review is common in decisions related to faculty advancement, a prototype professional peer-review process was recommended in the Ethics of the Physician written by Ishāq ibn ʻAlī al-Ruhāwī. He stated that a physician had to make duplicate notes of a patients condition on every visit. Professional peer review is common in the field of health care, further, since peer review activity is commonly segmented by clinical discipline, there is also physician peer review, nursing peer review, dentistry peer review, etc. Many other professional fields have some level of peer review process, accounting, law, engineering, aviation, and even forest fire management. Peer review is used in education to achieve certain learning objectives and this may take a variety of forms, including closely mimicking the scholarly peer review processes used in science and medicine. The peer review helps the publisher decide whether the work should be accepted, considered acceptable with revisions, peer review requires a community of experts in a given field, who are qualified and able to perform reasonably impartial review. Peer review is generally considered necessary to academic quality and is used in most major scientific journals, the European Union has been using peer review in the Open Method of Co-ordination of policies in the fields of active labour market policy since 1999. In 2004, a program of peer reviews started in social inclusion and these usually meet over two days and include visits to local sites where the policy can be seen in operation. The meeting is preceded by the compilation of a report on which participating peer countries submit comments. The results are published on the web, the State of California is the only U. S. state to mandate scientific peer review. This requirement is incorporated into the California Health and Safety Code Section 57004, thus, the terminology has poor standardization and specificity, particularly as a database search term

Scientific journal
–
In academic publishing, a scientific journal is a periodical publication intended to further the progress of science, usually by reporting new research. There are thousands of journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals such as Nature publish articles, Scientific journals contain articles that have been peer reviewed, in an attempt to ensure that articles meet the journals standards of quality, and scientific validity. If the journals editor considers the paper appropriate, at least two researchers preferably from the same field check the paper for soundness of its scientific argument, although scientific journals are superficially similar to professional magazines, they are actually quite different. Issues of a scientific journal are rarely read casually, as one would read a magazine, the publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results, each such journal article becomes part of the permanent scientific record. Over a thousand, mostly ephemeral, were founded in the 18th century, articles in scientific journals can be used in research and higher education. Scientific articles allow researchers to keep up to date with the developments of their field, an essential part of a scientific article is citation of earlier work. The impact of articles and journals is often assessed by counting citations, some classes are partially devoted to the explication of classic articles, and seminar classes can consist of the presentation by each student of a classic or current paper. Schoolbooks and textbooks have been written only on established topics, while the latest research. In a scientific research group or academic department it is usual for the content of current scientific journals to be discussed in journal clubs, the standards that a journal uses to determine publication can vary widely. Some journals, such as Nature, Science, PNAS, and it is also common for journals to have a regional focus, specializing in publishing papers from a particular country or other geographic region, like African Invertebrates. Articles tend to be technical, representing the latest theoretical research. They are often incomprehensible to anyone except for researchers in the field, in some subjects this is inevitable given the nature of the content. Usually, rigorous rules of writing are enforced by the editors, however. Articles are usually either original articles reporting new results or reviews of current literature. There are also publications that bridge the gap between articles and books by publishing thematic volumes of chapters from different authors. Research notes are short descriptions of current research findings that are considered less urgent or important than Letters, supplemental articles contain a large volume of tabular data that is the result of current research and may be dozens or hundreds of pages with mostly numerical data

Astronomy & Geophysics
–
Astronomy & Geophysics, also known as A&G, is a peer-reviewed scientific journal published on behalf of the Royal Astronomical Society by Oxford University Press. It was established in 1997 as a replacement for The Quarterly Journal of the Royal Astronomical Society, as of November 2016, it is edited by Sue Bowler. The journal covers astronomy, astrophysics, cosmology, planetary science, solar-terrestrial physics, global and regional geophysics, and it also publishes thematic articles regarding interdisciplinary research, science policy, news, opinions, correspondence, and book and software reviews. Royal Astronomical Society communications about events and people and obituaries are also within this journals purview, furthermore, in keeping with the tradition of the Quarterly Journal of the Royal Astronomical Society, it publishes discussions of fundamental science and scientific debates. The journal also functions as a channel of communication between the membership, the Council, and the Societys Officers, during that time 37 volumes were issued. It gave less emphasis to detailed scientific research papers, which instead were published in the societys Monthly Notices, before 1960 the Royal Astronomical Society had published proceedings of its activities in its Monthly Notices alongside research papers, and published research reviews in its Occasional Notes. The Quarterly Journal was established in 1960 to free the Monthly Notices to concentrate on research. The editor was successively David Dewhirst, C. Andrew Murray, jack Meadows, Simon Mitton, David W. Hughes, George H. A. Coles, Robert C. Smith, and David W. Hughes for a second time, series A Chemical Abstracts All articles are indexed, with abstracts, in the Astrophysics Data System, which includes scans of all pages.

Astronomer
–
An astronomer is a scientist in the field of astronomy who concentrates their studies on a specific question or field outside of the scope of Earth. They look at stars, planets, moons, comets and galaxies, as well as other celestial objects — either in observational astronomy. Examples of topics or fields astronomers work on include, planetary science, solar astronomy, there are also related but distinct subjects like physical cosmology which studies the Universe as a whole. Astronomers usually fit into two types, Observational astronomers make direct observations of planets, stars and galaxies, and analyze the data, theoretical astronomers create and investigate models of things that cannot be observed. They use this data to create models or simulations to theorize how different celestial bodies work, there are further subcategories inside these two main branches of astronomy such as planetary astronomy, galactic astronomy or physical cosmology. Today, that distinction has disappeared and the terms astronomer. Professional astronomers are highly educated individuals who typically have a Ph. D. in physics or astronomy and are employed by research institutions or universities. They spend the majority of their time working on research, although quite often have other duties such as teaching, building instruments. The number of astronomers in the United States is actually quite small. The American Astronomical Society, which is the organization of professional astronomers in North America, has approximately 7,000 members. This number includes scientists from other such as physics, geology. The International Astronomical Union comprises almost 10,145 members from 70 different countries who are involved in research at the Ph. D. level. Before CCDs, photographic plates were a method of observation. Modern astronomers spend relatively little time at telescopes usually just a few weeks per year, analysis of observed phenomena, along with making predictions as to the causes of what they observe, takes the majority of observational astronomers time. Astronomers who serve as faculty spend much of their time teaching undergraduate and graduate classes, most universities also have outreach programs including public telescope time and sometimes planetariums as a public service to encourage interest in the field. Those who become astronomers usually have a background in maths, sciences. Taking courses that teach how to research, write and present papers are also invaluable, in college/university most astronomers get a Ph. D. in astronomy or physics. Keeping in mind how few there are it is understood that graduate schools in this field are very competitive

Durham University
–
Durham University is a collegiate public research university in Durham, North East England, with a second campus in nearby Stockton-on-Tees. It was founded by an Act of Parliament in 1832 and granted a Royal Charter in 1837 and it was one of the first universities to commence tuition in England for more than 600 years and claims to be the third oldest university in England, although this is disputed. The Durham University estate includes 63 listed buildings, ranging from the 11th-century Durham Castle to a 1930s Art Deco Chapel, the university also owns and manages the Durham World Heritage Site in partnership with Durham Cathedral. The universitys ownership of the World Heritage Site includes Durham Castle, Palace Green, the chancellor of the University is Sir Thomas Allen, who succeeded Bill Bryson in January 2012. As a collegiate university, its functions are divided between the academic departments of the university and 16 colleges. The university is a member of the Russell Group of leading UK universities after previously being a member of the 1994 Group, Durham is also affiliated with several university groups including the N8 Research Partnership, the Matariki Network of Universities and the Coimbra Group. The university is currently ranked 4th to 6th by recent national league tables of the British universities, in terms of average UCAS points of new entrants in 2014, Durham ranked 4th with the average entrant amassing 524 UCAS points. Long established as the rival to Oxford and Cambridge, the university attracts a largely middle class student body according to The Timess Good University Guide. In 2014, Durham had the fifth highest proportion of educated students at 36. 6%. The university was Sunday Times University of the Year for 2005, also making the shortlist for the 2004 and 2016 awards, Durham graduates have long used the Latin post-nominal letters Dunelm after their degree, from Dunelmensis. However, there was concern expressed by Oxford and Cambridge that the awarding of degree powers could hinder their position. The act received Royal Assent from King William IV on 4 July 1832, the University opened on 28 October 1833. In 1834 all but two of the bishops of the Church of England confirmed that they would accept holders of Durham degrees for ordination, accommodation was provided in the Archdeacons Inn from 1833 to 1837. On the accession of Queen Victoria an order of the Queen-in-Council was issued granting the use of Durham Castle to the university, in 1846, Bishop Hatfields Hall was founded, providing for the opportunity for students to obtain affordable lodgings with fully catered communal eating. Those attending University College were expected to bring a servant with them to deal with cooking, cleaning, elsewhere, the university expanded from Durham into Newcastle in 1852 when the medical school there became a college of the university. This was joined in 1871 by the College of Physical Sciences and these merged to form a mixed college in 1975. From 1896 these were associated with the university and graduates of St Hilds were the first female graduates from Durham in 1898, during the expansion phase the University also became the first English university to establish relationship with overseas institutions. Firstly in 1875 with Codrington College, Barbados, and secondly in early 1876 with Fourah Bay College, under the arrangements the two colleges became affiliated colleges of the university with their students sitting examinations for and receiving Durham degrees

Portable Document Format
–
The Portable Document Format is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, PDF was developed in the early 1990s as a way to share computer documents, including text formatting and inline images. It was among a number of competing formats such as DjVu, Envoy, Common Ground Digital Paper, Farallon Replica, in those early years before the rise of the World Wide Web and HTML documents, PDF was popular mainly in desktop publishing workflows. Adobe Systems made the PDF specification available free of charge in 1993 and these proprietary technologies are not standardized and their specification is published only on Adobe’s website. Many of them are not supported by popular third-party implementations of PDF. So when organizations publish PDFs which use proprietary technologies, they present accessibility issues for some users. In 2014, ISO TC171 voted to deprecate XFA for ISO 32000-2, on January 9,2017, the final draft for ISO 32000-2 was published, thus reaching the approval stage. The PDF combines three technologies, A subset of the PostScript page description programming language, for generating the layout, a font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, PostScript is a page description language run in an interpreter to generate an image, a process requiring many resources. It can handle graphics and standard features of programming such as if. PDF is largely based on PostScript but simplified to remove flow control features like these, often, the PostScript-like PDF code is generated from a source PostScript file. The graphics commands that are output by the PostScript code are collected and tokenized, any files, graphics, or fonts to which the document refers also are collected. Then, everything is compressed to a single file, therefore, the entire PostScript world remains intact. PDF supports graphic transparency, PostScript does not, PostScript is an interpreted programming language with an implicit global state, so instructions accompanying the description of one page can affect the appearance of any following page. Therefore, all preceding pages in a PostScript document must be processed to determine the appearance of a given page. A PDF file is a 7-bit ASCII file, except for elements that may have binary content. A PDF file starts with a header containing the magic number, the format is a subset of a COS format. A COS tree file consists primarily of objects, of which there are eight types, Boolean values, representing true or false Numbers Strings, enclosed within parentheses, objects may be either direct or indirect

Astrophysics Data System

Abstracts are available free online for almost all articles, and full scanned articles are available in Graphics Interchange Format and Portable Document Format for older articles. New articles have links to electronic versions hosted at the webpage. It is managed by the Harvard–Smithsonian Center for Astrophysics, ADS is a powerful research tool and has had a significant impact on the efficiency of astronomical research since it was launched in 1992. Literature searches that previously would have taken days or weeks can now be carried out in seconds via the ADS search engine, use of ADS is almost universal among astronomers worldwide, and therefore ADS usage statistics can be used to analyze global trends in astronomical research. The first suggestion of a database of journal paper abstracts was made at a conference on Astronomy from Large Data-bases held in Garching bei München in 1987, the creators believed this was the first use of the Internet to allow simultaneous querying of transatlantic scientific databases. Until 1994, the service was available via proprietary network software, the number of users of the service quadrupled in the five weeks following the introduction of the ADS web-based service. ADS provided links to these electronic editions from their first appearance, since about 1995, the number of ADS users has doubled roughly every two years. ADS now has agreements with almost all astronomical journals, who supply abstracts, scanned articles from as far back as the early 19th century are available via the service, which now contains over eight million documents. All updates are triggered centrally, but they initiate scripts at the sites which pull updated data from the main ADS servers. Originally this data was stored in ASCII format, but eventually the limitations of this encouraged the database maintainers to migrate all records to an XML format in 2000, bibliographic records are now stored as an XML element, with sub-elements for the various metadata. Since the advent of online editions of journals, abstracts are loaded into the ADS on or before the date of articles. Older articles have been scanned, and an abstract is created using optical character recognition software, scanned articles from before about 1995 are usually available free, by agreement with the journal publishers. Scanned articles are stored in TIFF format, at medium and high resolution. The TIFF files are converted on demand into GIF files for on-screen viewing, the generated files are then cached to eliminate needlessly frequent regenerations for popular articles. As of 2000, ADS contained 250 GB of scans, which consisted of 1,128,955 article pages comprising 138,789 articles, by 2005 this had grown to 650 GB, and is expected to grow further, to about 900 GB by 2007. No further information has been published, the astronomy database is by far the most advanced and its use accounts for about 85% of the total ADS usage. Data in the preprint archive is updated daily from the arXiv, aDSs database links preprints with subsequently published articles wherever possible, so that citation and reference searches will return links to the journal article where the preprint was cited. Mirrors are located in Brazil, China, Chile, France, Germany, India, Indonesia, Japan, Russia, South Korea, United Kingdom, ADS currently receives abstracts or tables of contents from almost two hundred journal sources

ArXiv
–
In many fields of mathematics and physics, almost all scientific papers are self-archived on the arXiv repository. Begun on August 14,1991, arXiv. org passed the half-million article milestone on October 3,2008, by 2014 the submission rate had grown to more than 8,000 per month. The arXiv was made possible by the low-bandwidth TeX file format, around 1990, Joanne Cohn began emailing physics preprints to colleagues as TeX files, but the number of papers being sent soon filled mailboxes to capacity. Additional modes of access were added, FTP in 1991, Gopher in 1992. The term e-print was quickly adopted to describe the articles and its original domain name was xxx. lanl. gov. Due to LANLs lack of interest in the rapidly expanding technology, in 1999 Ginsparg changed institutions to Cornell University and it is now hosted principally by Cornell, with 8 mirrors around the world. Its existence was one of the factors that led to the current movement in scientific publishing known as open access. Mathematicians and scientists regularly upload their papers to arXiv. org for worldwide access, Ginsparg was awarded a MacArthur Fellowship in 2002 for his establishment of arXiv. The annual budget for arXiv is approximately $826,000 for 2013 to 2017, funded jointly by Cornell University Library, annual donations were envisaged to vary in size between $2,300 to $4,000, based on each institution’s usage. As of 14 January 2014,174 institutions have pledged support for the period 2013–2017 on this basis, in September 2011, Cornell University Library took overall administrative and financial responsibility for arXivs operation and development. Ginsparg was quoted in the Chronicle of Higher Education as saying it was supposed to be a three-hour tour, however, Ginsparg remains on the arXiv Scientific Advisory Board and on the arXiv Physics Advisory Committee. The lists of moderators for many sections of the arXiv are publicly available, additionally, an endorsement system was introduced in 2004 as part of an effort to ensure content that is relevant and of interest to current research in the specified disciplines. Under the system, for categories that use it, an author must be endorsed by an established arXiv author before being allowed to submit papers to those categories. Endorsers are not asked to review the paper for errors, new authors from recognized academic institutions generally receive automatic endorsement, which in practice means that they do not need to deal with the endorsement system at all. However, the endorsement system has attracted criticism for allegedly restricting scientific inquiry, perelman appears content to forgo the traditional peer-reviewed journal process, stating, If anybody is interested in my way of solving the problem, its all there – let them go and read about it. The arXiv generally re-classifies these works, e. g. in General mathematics, papers can be submitted in any of several formats, including LaTeX, and PDF printed from a word processor other than TeX or LaTeX. The submission is rejected by the software if generating the final PDF file fails, if any image file is too large. ArXiv now allows one to store and modify an incomplete submission, the time stamp on the article is set when the submission is finalized

Copyright
–
Copyright is a legal right created by the law of a country that grants the creator of an original work exclusive rights for its use and distribution. This is usually only for a limited time, the exclusive rights are not absolute but limited by limitations and exceptions to copyright law, including fair use. A major limitation on copyright is that copyright protects only the expression of ideas. Copyright is a form of property, applicable to certain forms of creative work. Some, but not all jurisdictions require fixing copyrighted works in a tangible form and it is often shared among multiple authors, each of whom holds a set of rights to use or license the work, and who are commonly referred to as rights holders. These rights frequently include reproduction, control over derivative works, distribution, public performance, copyrights are considered territorial rights, which means that they do not extend beyond the territory of a specific jurisdiction. While many aspects of copyright laws have been standardized through international copyright agreements. Typically, the duration of a copyright spans the authors life plus 50 to 100 years, some countries require certain copyright formalities to establishing copyright, but most recognize copyright in any completed work, without formal registration. Generally, copyright is enforced as a matter, though some jurisdictions do apply criminal sanctions. Most jurisdictions recognize copyright limitations, allowing fair exceptions to the exclusivity of copyright. Copyright came about with the invention of the press and with wider literacy. As a legal concept, its origins in Britain were from a reaction to printers monopolies at the beginning of the 18th century, Copyright laws allow products of creative human activities, such as literary and artistic production, to be preferentially exploited and thus incentivized. Different cultural attitudes, social organizations, economic models and legal frameworks are seen to account for why copyright emerged in Europe and not, for example, however, with copyright laws, intellectual production comes to be seen as a product of an individual, with attendant rights. The most significant point is that patent and copyright laws support the expansion of the range of human activities that can be commodified. This parallels the ways in which led to the commodification of many aspects of social life that earlier had no monetary or economic value per se. Often seen as the first real copyright law, the 1709 British Statute of Anne gave the rights for a fixed period. The act also alluded to individual rights of the artist and it began, Whereas Printers, Booksellers, and other Persons, have of late frequently taken the Liberty of Printing. Books, and other Writings, without the Consent of the Authors. to their very great Detriment, and too often to the Ruin of them and their Families

Roger Tayler
–
Professor Roger John Tayler OBE FRS was a British astronomer. In his scientific work, Professor Tayler made important contributions to stellar structure and evolution, plasma stability, nucleogenesis and he wrote a number of textbooks used by students world-wide. He collaborated with Fred Hoyle and Stephen Hawking at the University of Cambridge on problems of production in cosmology. In 1969 he was appointed professor of astronomy at Gresham College and he was Secretary, Treasurer and finally President of the Royal Astronomical Society. In March,1995 he was elected a Fellow of the Royal Society and his candidacy citation read Roger Taylers versatile career in Astronomy started with pioneering studies in stellar evolution, including his discovery of semi-convection. At Harwell, his work on plasma stability included a discussion of the stabilised pinch and he subsequently applied this expertise to a study of the stability of stellar magnetic fields and to the interaction of rotation and magnetic fields with convection. In cosmology, he calculated the cosmic helium abundance, stressing the importance of the number of neutrino types, in nucleosynthesis he calculated the abundances of iron peak elements produced at high temperatures, and recently he has been deeply involved with the chemical evolution of galaxies. He has written substantial and penetrating review articles, and text-books used the world over, in addition he has given outstanding public service, especially through the Royal Astronomical Society. He was appointed OBE in the 1990 New Year Honours

Arthur Cayley
–
Arthur Cayley F. R. S. was a British mathematician. He helped found the modern British school of pure mathematics, as a child, Cayley enjoyed solving complex maths problems for amusement. He entered Trinity College, Cambridge, where he excelled in Greek, French, German and he worked as a lawyer for 14 years. He postulated the Cayley–Hamilton theorem—that every square matrix is a root of its own characteristic polynomial and he was the first to define the concept of a group in the modern way—as a set with a binary operation satisfying certain laws. Formerly, when mathematicians spoke of groups, they had meant permutation groups, cayleys theorem is named in honour of Cayley. Arthur Cayley was born in Richmond, London, England, on 16 August 1821 and his father, Henry Cayley, was a distant cousin of Sir George Cayley the aeronautics engineer innovator, and descended from an ancient Yorkshire family. He settled in Saint Petersburg, Russia, as a merchant and his mother was Maria Antonia Doughty, daughter of William Doughty. According to some writers she was Russian, but her fathers name indicates an English origin and his brother was the linguist Charles Bagot Cayley. Arthur spent his first eight years in Saint Petersburg, in 1829 his parents were settled permanently at Blackheath, near London. Arthur was sent to a private school, at age 14 he was sent to Kings College School. The schools master observed indications of genius and advised the father to educate his son not for his own business, as he had intended. At the unusually early age of 17 Cayley began residence at Trinity College, Cambridge, the cause of the Analytical Society had now triumphed, and the Cambridge Mathematical Journal had been instituted by Gregory and Robert Leslie Ellis. To this journal, at the age of twenty, Cayley contributed three papers, on subjects that had been suggested by reading the Mécanique analytique of Lagrange, cayleys tutor at Cambridge was George Peacock and his private coach was William Hopkins. He finished his course by winning the place of Senior Wrangler. His next step was to take the M. A. degree and he continued to reside at Cambridge University for four years, during which time he took some pupils, but his main work was the preparation of 28 memoirs to the Mathematical Journal. Because of the tenure of his fellowship it was necessary to choose a profession, like De Morgan, Cayley chose law. He made a specialty of conveyancing and it was while he was a pupil at the bar examination that he went to Dublin to hear Hamiltons lectures on quaternions. During this period of his life, extending over fourteen years, at Cambridge University the ancient professorship of pure mathematics is denominated by the Lucasian, and is the chair that had been occupied by Isaac Newton

Richard A. Proctor
–
Richard Anthony Proctor was an English astronomer. He is best remembered for having produced one of the earliest maps of Mars in 1867 from 27 drawings by the English observer William Rutter Dawes and his map was later superseded by those of Giovanni Schiaparelli and Eugène Antoniadi and his nomenclature was dropped. He used old drawings of Mars dating back to 1666 to try to determine the day of Mars. His final estimate, in 1873, was 24h 37m 22. 713s, nevertheless, Frederik Kaisers value of 24h 37m 22. 622s is closer, by 0.012 seconds in 88,642.688 seconds, a very small difference in the error of both computations. A crater on Mars is named after Proctor and he was a delicate child, and, his father dying in 1850, his mother attended herself to his education. On his health improving he was sent to Kings College London and he graduated in 1860 as 23rd wrangler. His marriage while still an undergraduate probably accounted for his low place in the tripos and he then read for the bar, but turned to astronomy and authorship instead, and in 1865 published an article on the Colors of Double Stars in the Cornhill Magazine. His first book Saturn and its System was published in the same year and this work contains an elaborate account of the phenomena presented by the planet, but although favourably received by astronomers, it had no great sale. His earlier efforts were, however, not always successful and his Handbook of the Stars was refused by Messrs Longmans and Messrs Macmillan, but being privately printed, it sold fairly well. For his Half-Hours with the Telescope, which reached a 20th edition. Although teaching was uncongenial to him he took pupils in mathematics and his literary standing meantime improved, and he became a regular contributor to The Intellectual Observer, Chambers Journal and the Popular Science Review. In 1870 appeared his Other Worlds Than Ours, in which he discussed the question of the plurality of worlds in the light of new facts, in 1881 he founded Knowledge, a popular weekly magazine of science, which had a considerable circulation. In it he wrote on a variety of subjects, including chess. Elected a fellow of the Royal Astronomical Society in 1866, he became secretary in 1872. Of these the more noteworthy dealt with the distribution of stars, star clusters and nebulae, and he was an expert in all that related to map-drawing, and published two star-atlases. His Theoretical Considerations respecting the Corona also deserve mention, as well as his discussions of the rotation of Mars and he also vigorously criticised the official arrangements for observing the transits of Venus of 1874 and 1882. His largest and most ambitious work, Old and New Astronomy, left unfinished at his death, was completed by Arthur Cowper Ranyard and he settled in America some time after his second marriage in 1881, and died of yellow fever at New York City on 12 September 1888. A monument was erected in his memory
