110-488: LaTeX is widely used in academia for the communication and publication of scientific documents and technical note-taking in many fields, owing partially to its support for complex mathematical notation. It also has a prominent role in the preparation and publication of books and articles that contain complex multilingual materials , such as Arabic and Greek . LaTeX uses the TeX typesetting program for formatting its output, and

220-510: A Document type declaration (informally, a "doctype"). In browsers, the doctype helps to define the rendering mode—particularly whether to use quirks mode . The original purpose of the doctype was to enable the parsing and validation of HTML documents by SGML tools based on the Document type definition (DTD). The DTD to which the DOCTYPE refers contains a machine-readable grammar specifying

330-485: A voiceless velar fricative as in Modern Greek, similar to the ch in loch ). Lamport remarks that "TeX is usually pronounced tech , making lah -tech, lah- tech , and lay -tech the logical choices; but language is not always logical, so lay-tecks is also possible." The name is printed in running text with a typographical logo : L a T e X . In media where the logo cannot be precisely reproduced in running text,

440-486: A web browser . It defines the content and structure of web content . It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript, a programming language. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for its appearance. HTML elements are

550-472: A TeX Users Group (TUG) meeting at Stanford, Lamport agreed to turn over maintenance and development of LaTeX to Frank Mittelbach . Frank Mittelbach, along with Chris Rowley and Rainer Schöpf, formed the LaTeX3 team; in 1994, they released LaTeX2e, the current standard version. LaTeX3 has since been cancelled with features intended for that version being back-ported to LaTeX2e since 2018. LaTeX attempts to follow

660-407: A contractor at CERN , proposed and prototyped ENQUIRE , a system for CERN researchers to use and share documents. In 1989, Berners-Lee wrote a memo proposing an Internet -based hypertext system. Berners-Lee specified HTML and wrote the browser and server software in late 1990. That year, Berners-Lee and CERN data systems engineer Robert Cailliau collaborated on a joint request for funding, but

770-604: A document in LaTeX, a user first creates a file, such as document.tex , typically using a text editor . The user then gives their document.tex file as input to the TeX program (with the LaTeX macros loaded), which prompts TeX to write out a file suitable for onscreen viewing or printing. This write-format-preview cycle is one of the chief ways in which working with LaTeX differs from the What-You-See-Is-What-You-Get (WYSIWYG) style of document editing. It

880-526: A document, it follows (from the user's point of view) the following processing sequence: Macros → TeX → Driver → Output. Different implementations of each of these steps are typically available in TeX distributions. Traditional TeX will output a DVI file, which is usually converted to a PostScript file. In 2000, Hàn Thế Thành and others wrote an implementation of TeX called pdfTeX , which also outputs to PDF and takes advantage of features available in that format. The XeTeX engine developed by Jonathan Kew, on

990-506: A great influence on Renaissance Neo-Platonism . In Rome, after unity was restored following the Western Schism , humanist circles, cultivating philosophy and searching out and sharing ancient texts tended to gather where there was access to a library. The Vatican Library was not coordinated until 1475 and was never catalogued or widely accessible: not all popes looked with satisfaction at gatherings of unsupervised intellectuals. At

1100-407: A little extra effort, he could make a general package usable by others. Peter Gordon, an editor at Addison-Wesley , convinced him to write a LaTeX user's manual for publication (Lamport was initially skeptical that anyone would pay money for it); it came out in 1986 and sold hundreds of thousands of copies. Meanwhile, Lamport released versions of his LaTeX macros in 1984 and 1985. On 21 August 1989, at

1210-451: A pair is the start tag , and the second is the end tag (they are also called opening tags and closing tags ). Another important component is the HTML document type declaration , which triggers standards mode rendering. The following is an example of the classic "Hello, World!" program : The text between < html > and </ html > describes the web page, and

1320-492: A result, it encourages the separation of the layout from the content — while still allowing manual typesetting adjustments whenever needed. This concept is similar to the mechanism by which many word processors allow styles to be defined globally for an entire document, or the use of Cascading Style Sheets in styling HyperText Markup Language ( HTML ) documents. The LaTeX system is a markup language that handles typesetting and rendering, and can be arbitrarily extended by using

1430-402: A rule these academies, all very much alike, were merely circles of friends or clients gathered around a learned man or wealthy patron, and were dedicated to literary pastimes rather than methodical study. They fitted in, nevertheless, with the general situation and were in their own way one element of the historical development. Despite their empirical and fugitive character, they helped to keep up

1540-425: A start tag) and do not use an end tag. Many tags, particularly the closing end tag for the very commonly used paragraph element < p > , are optional. An HTML browser or other agent can infer the closure for the end of an element from the context and the structural rules defined by the HTML standard. These rules are complex and not widely understood by most HTML authors. The general form of an HTML element

1650-546: A teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. The word comes from the Academy in ancient Greece , which derives from the Athenian hero , Akademos . Outside the city walls of Athens , the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena , had formerly been an olive grove , hence

1760-596: A user can give input/s like: Comments: Comments can help in the understanding of the markup and do not display in the webpage. There are several types of markup elements used in HTML: Most of the attributes of an element are name–value pairs , separated by = and written within the start tag of an element after the element's name. The value may be enclosed in single or double quotes, although values consisting of certain characters can be left unquoted in HTML (but not XHTML). Leaving attribute values unquoted

1870-426: A writing tool for mathematicians and computer scientists, but even from early in its development, it has also been taken up by scholars who needed to write documents that include complex math expressions or non-Latin scripts, such as Arabic , Devanagari and Chinese . LaTeX is intended to provide a high-level, descriptive markup language to utilize TeX more easily. TeX handles the document layout, while LaTeX handles

1980-458: Is Debian Free Software Guidelines (DFSG) compliant as of version 1.3. As free software , LaTeX is available on most operating systems, which include Unix ( Solaris , HP-UX , AIX ), BSD ( FreeBSD , macOS , NetBSD , OpenBSD ), Linux ( Red Hat , Debian , Arch , Gentoo ), Windows , DOS , RISC OS , AmigaOS , and Plan 9 . LaTeX2e is the current version of LaTeX, since it replaced LaTeX 2.09 in 1994. As of 2020, LaTeX3, which started in

2090-558: Is LaTeX2e, first released in 1994 but incrementally updated starting in 2015. This update policy replaced earlier plans for a separate release of LaTeX3, which had been in development since 1989. LaTeX is free software and is distributed under the LaTeX Project Public License (LPPL) . LaTeX was created in the early 1980s by Leslie Lamport when he was working at Stanford Research Institute (SRI). He needed to write TeX macros for his own use and thought that with

2200-444: Is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato 's school of philosophy , founded approximately 386 BC at Akademia , a sanctuary of Athena , the goddess of wisdom and skill , north of Athens , Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as

2310-464: Is considered unsafe. In contrast with name-value pair attributes, there are some attributes that affect the element simply by their presence in the start tag of the element, like the ismap attribute for the img element. There are several common attributes that may appear in many elements : The abbreviation element, abbr , can be used to demonstrate some of these attributes: This example displays as HTML ; in most browsers, pointing

2420-456: Is for HTML5. If a declaration is not included, various browsers will revert to " quirks mode " for rendering. HTML documents imply a structure of nested HTML elements . These are indicated in the document by HTML tags , enclosed in angle brackets thus: < p > . In the simple, general case, the extent of an element is indicated by a pair of tags: a "start tag" < p > and "end tag" </ p > . The text content of

2530-627: Is itself written in the TeX macro language. LaTeX can be used as a standalone document preparation system, or as an intermediate format. In the latter role, for example, it is sometimes used as part of a pipeline for translating DocBook and other XML -based formats for PDF . The typesetting system offers programmable desktop publishing features and extensive facilities for automating most aspects of typesetting and desktop publishing, including numbering and cross-referencing of tables and figures, chapter and section headings, graphics, page layout, indexing and bibliographies . Like TeX, LaTeX started as

2640-715: Is said to have been composed in Takshashila itself. Chanakya (or Kautilya), the Maurya Emperor Chandragupta and the Ayurvedic healer Charaka studied at Taxila. Generally, a student entered Takshashila at the age of sixteen. The Vedas and the Eighteen Arts , which included skills such as archery , hunting , and elephant lore, were taught, in addition to its law school , medical school , and school of military science . Nalanda

2750-401: Is similar to the code-compile-execute cycle known to computer programmers. Today, many LaTeX-aware editing programs make this cycle a simple matter through the pressing of a single key, while showing the output preview on the screen beside the input window. Some online LaTeX editors even automatically refresh the preview, while other online tools provide incremental editing in-place, mixed in with

2860-401: Is therefore: < tag attribute1 = "value1" attribute2 = "value2" > ''content'' </ tag > . Some HTML elements are defined as empty elements and take the form < tag attribute1 = "value1" attribute2 = "value2" > . Empty elements may enclose no content, for instance, the < br /> tag or

2970-576: Is typically distributed along with plain TeX under a free software license : the LaTeX Project Public License (LPPL). The LPPL is not compatible with the GNU General Public License , as it requires that modified files must be clearly differentiable from their originals (usually by changing the filename); this was done to ensure that files that depend on other files will produce the expected behavior and avoid dependency hell . The LPPL

3080-605: The Accademia Pontaniana , after Giovanni Pontano . The 16th century saw at Rome a great increase of literary and aesthetic academies, more or less inspired by the Renaissance, all of which assumed, as was the fashion, odd and fantastic names. We learn from various sources the names of many such institutes; as a rule, they soon perished and left no trace. In the 1520s came the Accademia degli Intronati , for

3190-717: The Accademia di Santa Cecilia for music from 1585; Paris had the Académie Royale de Musique from 1669 and the Académie Royale d'Architecture from 1671. The Accademia degli Infiammati of Padova and the Accademia degli Umidi, soon renamed the Accademia Fiorentina , of Florence were both founded in 1540, and were both initially concerned with the proper basis for literary use of the volgare , or vernacular language of Italy, which would later become

3300-583: The Guild of Saint Luke , as the bodies responsible for training and often regulating artists, a change with great implications for the development of art, leading to the styles known as Academic art . The private Accademia degli Incamminati set up later in the century in Bologna by the Carracci brothers was also extremely influential, and with the Accademia di San Luca of Rome (founded 1593) helped to confirm

3410-1008: The Göttingen Academy of Sciences , in 1754 in Erfurt , in 1759 the Bavarian Academy of Sciences and Humanities , in 1763 the Academia Theodoro-Palatina in Heidelberg , in 1779 the Sciences Academy of Lisbon , in 1783 the Royal Society of Edinburgh , in 1782 the Accademia dei Quaranta in Rome, in 1784 in Turin .

The draft expired after six months, but was notable for its acknowledgment of the NCSA Mosaic browser's custom tag for embedding in-line images, reflecting

3630-683: The Italian language . In 1582 five Florentine literati gathered and founded the Accademia della Crusca to demonstrate and conserve the beauty of the Florentine vernacular tongue, modelled upon the authors of the Trecento. The main instrument to do so was the Vocabolario degli Accademici della Crusca . The Crusca long remained a private institution, criticizing and opposing the official Accademia Fiorentina. The first institution inspired by

3740-611: The New Academy . In 335 BC, Aristotle refined the method with his own theories and established the Lyceum in another gymnasium. The Musaeum , Serapeum and library of Alexandria Egypt was frequented by intellectuals from Africa, Europe and Asia studying various aspects of philosophy, language and mathematics. The University of Timbuktu was a medieval university in Timbuktu , present-day Mali, which comprised three schools:

3850-570: The Quadrivium ( Arithmetic , Geometry , Music , and Astronomy )—had been codified in late antiquity . This was the basis of the curriculum in Europe until newly available Arabic texts and the works of Aristotle became more available in Europe in the 12th century. It remained in place even after the new scholasticism of the School of Chartres and the encyclopedic work of Thomas Aquinas , until

3960-826: The Real Academia de Bellas Artes de San Fernando in Madrid (founded 1744), the Imperial Academy of Arts in Saint Petersburg (1757), the Royal Academy in London (1768) and the Accademia di Belle Arti di Brera in Milan (1776) still run art schools and hold large exhibitions, although their influence on taste greatly declined from the late 19th century. A fundamental feature of academic discipline in

4070-614: The Sabians ). The Grand School was the main center of learning in the Persian capital Ctesiphon , but little is known about it. Perhaps the most famous center of learning in Persia was the Academy of Gundishapur , teaching medicine, mathematics, astronomy, and logic. The academy was later instrumental in founding the Muslim city of Baghdad as a center of learning, and serving as the model for

4180-434: The de facto web standard for some time. HTML markup consists of several key components, including those called tags (and their attributes ), character-based data types , character references and entity references . HTML tags most commonly come in pairs like < h1 > and </ h1 > , although some represent empty elements and so are unpaired, for example < img > . The first tag in such

4290-523: The " Animosi " (1576), and the " Illuminati " (1598); this last, founded by the Marchesa Isabella Aldobrandini Pallavicino . Towards the middle of the 16th century there were also the academy of the " Notti Vaticane ", or " Vatican Nights ", founded by St . Charles Borromeo ; an "Accademia di Diritto civile e canonico", and another of the university scholars and students of philosophy ( Accademia Eustachiana ). As

4400-453: The 17th century, British, Italian and French scholars used the term to describe types of institutions of higher learning. Before Akademia was a school, and even before Cimon enclosed its precincts with a wall, it contained a sacred grove of olive trees dedicated to Athena , the goddess of wisdom , outside the city walls of ancient Athens . The archaic name for the site was Hekademia , which by classical times evolved into Akademia and

4510-633: The Academy"). Other notable members of Akademia include Aristotle , Heraclides Ponticus , Eudoxus of Cnidus , Philip of Opus , Crantor , and Antiochus of Ascalon . After a lapse during the early Roman occupation, Akademia was refounded as a new institution of some outstanding Platonists of late antiquity who called themselves "successors" ( diadochoi , but of Plato) and presented themselves as an uninterrupted tradition reaching back to Plato. However, there cannot have actually been any geographical, institutional, economic or personal continuity with

4620-628: The Byzantine empire in 532 guaranteed their personal security (an early document in the history of freedom of religion ), some members found sanctuary in the pagan stronghold of Harran , near Edessa . One of the last leading figures of this group was Simplicius, a pupil of Damascius, the last head of the Athenian school. It has been speculated that Akademia did not altogether disappear. After his exile, Simplicius (and perhaps some others), may have travelled to Harran , near Edessa . From there,

4730-843: The Caliph. The collection was said to have grown to 400,000 volumes. In Europe, the academy dates to the ancient Greeks and Romans in the pre-Christian era. Newer universities were founded in the 12th and 13th centuries, and the European institution of academia took shape. Monks and priests moved out of monasteries to cathedral cities and other towns where they opened the first schools dedicated to advanced study. The most notable of these new schools were in Bologna and Salerno , Naples , Salamanca , Paris , Oxford and Cambridge , while others were opened throughout Europe. The seven liberal arts —the Trivium ( Grammar , Rhetoric , and Logic ), and

4840-641: The Crusca was the Fruitbearing Society for German language, which existed from 1617 to 1680. The Crusca inspired Richelieu to found in 1634 the analogous Académie française with the task of acting as an official authority on the French language , charged with publishing the official dictionary of that language. The following year the Académie received letters patent from the king Louis XIII as

4950-456: The IETF's philosophy of basing standards on successful prototypes. Similarly, Dave Raggett 's competing Internet Draft, "HTML+ (Hypertext Markup Format)", from late 1993, suggested standardizing already-implemented features like tables and fill-out forms. After the HTML and HTML+ drafts expired in early 1994, the IETF created an HTML Working Group. In 1995, this working group completed "HTML 2.0",

5060-582: The LaTeX file to other formats such as OpenDocument , XML , or class ( *.cls ) files. LaTeX can also (and commonly is) rendered to PDF files using the LaTeX extension pdfLaTeX. LaTeX files containing Unicode text can be processed into PDFs with the inputenc package, or by the TeX extensions XeLaTeX and LuaLaTeX. LaTeX has become the de facto standard to typeset mathematical expression in scientific documents. Hence, there are several conversion tools focusing on mathematical LaTeX expressions, such as converters to MathML or Computer Algebra System . LaTeX

5170-510: The Mosque of Djinguereber, the Mosque of Sidi Yahya, and the Mosque of Sankore. During its zenith, the university had an average attendance of around 25,000 students within a city of around 100,000 people. In China a higher education institution Shang Xiang was founded by Shun in the Youyu era before the 21st century BC. The Imperial Central Academy at Nanjing , founded in 258, was a result of

5280-596: The XML syntax for HTML and is no longer being developed as a separate standard. On 28 May 2019, the W3C announced that WHATWG would be the sole publisher of the HTML and DOM standards. The W3C and WHATWG had been publishing competing standards since 2012. While the W3C standard was identical to the WHATWG in 2007 the standards have since progressively diverged due to different design decisions. The WHATWG "Living Standard" had been

5390-580: The academic circle, like Publio Fausto Andrelini of Bologna who took the New Learning to the University of Paris , to the discomfiture of his friend Erasmus . In their self-confidence, these first intellectual neopagans compromised themselves politically, at a time when Rome was full of conspiracies fomented by the Roman barons and the neighbouring princes: Paul II (1464–71) caused Pomponio and

5500-643: The academy of Oscuri became the Royal Academy of Lucca . The Académie de peinture et de sculpture in Paris, established by the monarchy in 1648 (later renamed) was the most significant of the artistic academies, running the famous Salon exhibitions from 1725. Artistic academies were established all over Europe by the end of the 18th century, and many, like the Akademie der Künste in Berlin (founded 1696),

5610-460: The academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to Royal Society , the academy was founded as an organ of government. In 1699, Louis XIV gave the academy its first rules and named it Académie royale des sciences . Although Prussia was a member of Holy Roman Empire, in 1700 Prince-elector Frederick III of Brandenburg founded its own Prussian Academy of Sciences upon

5720-831: The advice of Gottfried Leibniz , who was appointed president. During the 18th century many European kings followed and founded their own academy of sciences: in 1714 the Academy of Sciences of the Institute of Bologna , in 1724 the Russian Academy of Sciences , in 1731 the Royal Dublin Society , in 1735 in Tuscany , in 1739 the Royal Swedish Academy of Sciences , in 1742 the Royal Danish Academy of Sciences and Letters , in 1751

5830-684: The art of war. The center had eight separate compounds, 10 temples, meditation halls, classrooms, lakes and parks. It had a nine-story library where monks meticulously copied books and documents so that individual scholars could have their own collections. It had dormitories for students, perhaps a first for an educational institution, housing 10,000 students in the university's heyday and providing accommodation for 2,000 professors. Nalanda University attracted pupils and scholars from Korea, Japan, China, Tibet, Indonesia, Persia and Turkey. The geographical position of Persia allowed it to absorb cultural influences and ideas from both west and east. This include

5940-551: The artistic academies was regular practice in making accurate drawings from antiquities, or from casts of antiquities, on the one hand, and on the other, in deriving inspiration from the other fount, the human form. Students assembled in sessions drawing the draped and undraped human form , and such drawings, which survive in the tens of thousands from the 17th through the 19th century, are termed académies in French. Similar institutions were often established for other arts: Rome had

6050-473: The attribute value itself. If document authors overlook the need to escape such characters, some browsers can be very forgiving and try to use context to guess their intent. The result is still invalid markup, which makes the document less accessible to other browsers and to other user agents that may try to parse the document for search and indexing purposes for example. Escaping also allows for characters that are not easily typed, or that are not available in

6160-574: The browser, and these characteristics can be altered or enhanced by the web page designer's additional use of CSS . Many of the text elements are mentioned in the 1988 ISO technical report TR 9537 Techniques for using SGML , which describes the features of early text formatting languages such as that used by the RUNOFF command developed in the early 1960s for the CTSS (Compatible Time-Sharing System) operating system. These formatting commands were derived from

6270-486: The building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links , quotes, and other items. HTML elements are delineated by tags , written using angle brackets . Tags such as < img > and < input > directly introduce content into

6380-433: The characters < and & (when written as &lt; and &amp; , respectively) to be interpreted as character data, rather than markup. For example, a literal < normally indicates the start of a tag, and & normally indicates the start of a character entity reference or numeric character reference; writing it as &amp; or &#x26; or &#38; allows & to be included in

6490-441: The characters of the world's writing systems. HTML defines several data types for element content, such as script data and stylesheet data, and a plethora of types for attribute values, including IDs, names, URIs , numbers, units of length, languages, media descriptors, colors, character encodings, dates and times, and so on. All of these data types are specializations of character data. HTML documents are required to start with

6600-518: The classic philosophy. The next generation of humanists were bolder admirers of pagan culture, especially in the highly personal academy of Pomponius Leto , the natural son of a nobleman of the Sanseverino family, born in Calabria but known by his academic name, who devoted his energies to the enthusiastic study of classical antiquity, and attracted a great number of disciples and admirers. He

6710-451: The commands used by typesetters to manually format documents. However, the SGML concept of generalized markup is based on elements (nested annotated ranges with attributes) rather than merely print effects, with separate structure and markup. HTML has been progressively moved in this direction with CSS. Berners-Lee considered HTML to be an application of SGML. It was formally defined as such by

SECTION 60

#1732772567114

6820-539: The content of an element or in the value of an attribute. The double-quote character ( " ), when not used to quote an attribute value, must also be escaped as &quot; or &#x22; or &#34; when it appears within the attribute value itself. Equivalently, the single-quote character ( ' ), when not used to quote an attribute value, must also be escaped as &#x27; or &#39; (or as &apos; in HTML5 or XHTML documents ) when it appears within

6930-460: The content side for document processing. LaTeX comprises a collection of TeX macros and a program to process LaTeX documents, and because the plain TeX formatting commands are elementary, it provides authors with ready-made commands for formatting and layout requirements such as chapter headings, footnotes, cross-references and bibliographies. LaTeX was originally written in the early 1980s by Leslie Lamport at SRI International . The current version

7040-664: The cursor at the abbreviation should display the title text "Hypertext Markup Language." Most elements take the language-related attribute dir to specify text direction, such as with "rtl" for right-to-left text in, for example, Arabic , Persian or Hebrew . As of version 4.0, HTML defines a set of 252 character entity references and a set of 1,114,050 numeric character references , both of which allow individual characters to be written via simple markup, rather than literally. A literal character and its markup counterpart are considered equivalent and are rendered identically. The ability to " escape " characters in this way allows for

7150-433: The design philosophy of separating presentation from content , so that authors can focus on the content of what they are writing without attending simultaneously to its visual appearance. In preparing a LaTeX document, the author specifies the logical structure using simple, familiar concepts such as chapter , section , table , figure , etc., and lets the LaTeX system handle the formatting and layout of these structures. As

7260-589: The document's character encoding , to be represented within the element and attribute content. For example, the acute-accented e ( é ), a character typically found only on Western European and South American keyboards, can be written in any HTML document as the entity reference &eacute; or as the numeric references &#xE9; or &#233; , using characters that are available on all keyboards and are supported in all character encodings. Unicode character encodings such as UTF-8 are compatible with all modern browsers and allow direct access to almost all

7370-487: The early 1990s, is under a long-term development project. Planned features include improved syntax (separation of content from styling), hyperlink support, a new user interface, access to arbitrary fonts and a new documentation. Some LaTeX3 features are available in LaTeX2e using packages, and by 2020 many features have been enabled in LaTeX2e by default for a gradual transition. There are many commercial implementations of

7480-445: The element, if any, is placed between these tags. Tags may also enclose further tag markup between the start and end, including a mixture of tags and text. This indicates further (nested) elements, as children of the parent element. The start tag may also include the element's attributes within the tag. These indicate other information, such as identifiers for sections within the document, identifiers used to bind style information to

7590-408: The encouragement of theatrical representations. There were also the academy of the " Vignaiuoli ", or " Vinegrowers " (1530), and the Accademia della Virtù  [ it ] (1542), founded by Claudio Tolomei under the patronage of Cardinal Ippolito de' Medici . These were followed by a new academy in the " Orti " or Farnese gardens. There were also the academies of the " Intrepidi " (1560),

7700-590: The entire TeX system. System vendors may add extra features like added typefaces and telephone support . LyX is a free software , WYSIWYM visual document processor that uses LaTeX for a back-end. TeXmacs is a free, WYSIWYG editor with similar functionalities as LaTeX, but with a different typesetting engine. Other WYSIWYG editors that produce LaTeX include Scientific Word on Windows, and BaKoMa TeX on Windows, Mac and Linux. Many community-supported TeX distributions are available. Academia An academy ( Attic Greek : Ἀκαδήμεια; Koine Greek Ἀκαδημία)

7810-663: The evolution of Shang Xiang and it became the first comprehensive institution combining education and research and was divided into five faculties in 470, which later became Nanjing University . In the 8th century another kind of institution of learning emerged, named Shuyuan , which were generally privately owned. There were thousands of Shuyuan recorded in ancient times. The degrees from them varied from one to another and those advanced Shuyuan such as Bailudong Shuyuan and Yuelu Shuyuan (later become Hunan University ) can be classified as higher institutions of learning. Taxila or Takshashila , in ancient India , modern-day Pakistan,

7920-479: The expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy . By extension, academia has come to mean the accumulation, development and transmission of knowledge across generations as well as its practitioners and transmitters. In

8030-517: The first HTML specification intended to be treated as a standard against which future implementations should be based. Further development under the auspices of the IETF was stalled by competing interests. Since 1996, the HTML specifications have been maintained, with input from commercial software vendors, by the World Wide Web Consortium (W3C). In 2000, HTML became an international standard ( ISO / IEC 15445:2000). HTML 4.01

8140-694: The first Muslim hospital ( bimaristan ) at Damascus. Founded in Fes, University of Al-Karaouine in the 9th century and in Cairo, Al-Azhar University in the 10th century, and in Mali, the University of Timbuktu in about 1100. Mustansiriya Madrasah in Baghdad , Iraq was established in 1227 as a madrasah by the Abbasid Caliph al-Mustansir . Its library had an initial collection of 80,000 volumes, given by

8250-546: The first half of the 19th century some of these became the national academies of pre-unitarian states: the academy of Accesi became the Panomitan Academy of Buon Gusto ( Trento ); the academy of Timidi became the Royal Academy of Mantua ; the Accademia dei Ricovrati became the Galileiana Academy of Arts and Science ( Padova ); the academy of Dissonanti became the Royal Academy of Modena and

8360-566: The formation of a "College for the Promoting of Physico-Mathematical Experimental Learning", which would meet weekly to discuss science and run experiments. In 1662 Charles II of England signed a Royal Charter which created the "Royal Society of London", then "Royal Society of London for the Improvement of Natural Knowledge". In 1666 Colbert gathered a small group of scholars to found a scientific society in Paris. The first 30 years of

8470-488: The general esteem for literary and other studies. Cardinals, prelates, and the clergy in general were most favourable to this movement, and assisted it by patronage and collaboration. In Florence, the Medici again took the lead in establishing the Accademia e Compagnia delle Arti del Disegno in 1563, the first of the more formally organised art academies that gradually displaced the medieval artists' guilds , usually known as

8580-485: The head of this movement for renewal in Rome was Cardinal Bessarion , whose house from the mid-century was the centre of a flourishing academy of Neoplatonic philosophy and a varied intellectual culture. His valuable Greek as well as Latin library (eventually bequeathed to the city of Venice after he withdrew from Rome) was at the disposal of the academicians. Bessarion, in the latter years of his life, retired from Rome to Ravenna , but he left behind him ardent adherents of

8690-412: The head, for example: HTML headings are defined with the < h1 > to < h6 > tags with H1 being the highest (or most important) level and H6 the least: The effects are: CSS can substantially change the rendering. Paragraphs: < br /> . The difference between < br /> and < p > is that < br /> breaks a line without altering

8800-551: The humanism of the 15th and 16th centuries opened new studies of arts and sciences. With the Neoplatonist revival that accompanied the revival of humanist studies , academia took on newly vivid connotations. During the Florentine Renaissance , Cosimo de' Medici took a personal interest in the new Platonic Academy that he determined to re-establish in 1439, centered on the marvellous promise shown by

8910-425: The hyperlink tag, these were strongly influenced by SGMLguid , an in-house Standard Generalized Markup Language (SGML)-based documentation format at CERN. Eleven of these elements still exist in HTML 4. HTML is a markup language that web browsers use to interpret and compose text, images, and other material into visible or audible web pages. Default characteristics for every item of HTML markup are defined in

9020-402: The inline < img > tag. The name of an HTML element is the name used in the tags. The end tag's name is preceded by a slash character, / , and that in empty elements the end tag is neither required nor allowed. If attributes are not mentioned, default values are used in each case. Header of the HTML document: < head > ... </ head > . The title is included in

9130-600: The leaders of the academy to be arrested on charges of irreligion, immorality, and conspiracy against the Pope . The prisoners begged so earnestly for mercy, and with such protestations of repentance, that they were pardoned. The Letonian academy, however, collapsed. In Naples, the Quattrocento academy founded by Alfonso of Aragon and guided by Antonio Beccadelli was the Porticus Antoniana , later known as

9240-465: The look and layout of content. The World Wide Web Consortium (W3C), former maintainer of the HTML and current maintainer of the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997. A form of HTML, known as HTML5 , is used to display video and audio, primarily using the < canvas > element, together with JavaScript. In 1980, physicist Tim Berners-Lee ,

9350-626: The only recognized academy for French language. In its turn the state established Académie was the model for the Real Academia Española (founded in 1713) and the Swedish Academy (1786), which are the ruling bodies of their respective languages and editors of major dictionaries. It also was the model for the Russian Academy , founded in 1783, which afterwards merged into the Russian Academy of Sciences. After

9460-625: The original Academy in the new organizational entity. The last "Greek" philosophers of the revived Akademia in the 6th century were drawn from various parts of the Hellenistic cultural world and suggest the broad syncretism of the common culture (see koine ): Five of the seven Akademia philosophers mentioned by Agathias were Syriac in their cultural origin: Hermias and Diogenes (both from Phoenicia), Isidorus of Gaza, Damascius of Syria, Iamblichus of Coele-Syria and perhaps even Simplicius of Cilicia . The emperor Justinian ceased

9570-536: The other hand, merges modern font technologies and Unicode with TeX. LuaTeX is an extended version of pdfTeX using Lua as an embedded scripting language. There are also many editors for LaTeX, some of which are offline, source-code-based while others are online, partial-WYSIWYG-based. For more, see Comparison of TeX editors . LaTeX documents ( *.tex ) can be opened with any text editor. They consist of plain text and contain no hidden formatting codes or binary information. TeX documents can also be shared by rendering

9680-413: The page. Other tags such as < p > and </ p > surround and provide information about document text and may include sub-element tags. Browsers do not display the HTML tags but use them to interpret the content of the page. HTML can embed programs written in a scripting language such as JavaScript , which affects the behavior and content of web pages. The inclusion of CSS defines

9790-483: The permitted and prohibited content for a document conforming to such a DTD. Browsers, on the other hand, do not implement HTML as an application of SGML and as consequence do not read the DTD. HTML5 does not define a DTD; therefore, in HTML5 the doctype declaration is simpler and shorter: An example of an HTML 4 doctype This declaration references the DTD for the "strict" version of HTML 4.01. SGML-based validators read

9900-412: The presentation of the document, and for some tags such as the < img > used to embed images, the reference to the image resource in the format like this: < img src = "example.com/example.jpg" > Some elements, such as the line break < br /> do not permit any embedded content, either text or further tags. These require only a single empty tag (akin to

10010-579: The preview in a streamlined single window. The example below shows the input to LaTeX and the corresponding output from the system: The characters 'T', 'E', and 'X' in the name come from the Greek capital letters tau , epsilon , and chi , as the name of TeX derives from the Ancient Greek : τέχνη ('skill', 'art', 'technique'); for this reason, TeX's creator Donald Knuth promotes its pronunciation as / t ɛ x / ( tekh ) (that is, with

10120-491: The project was not formally adopted by CERN. In his personal notes of 1990, Berners-Lee listed "some of the many areas in which hypertext is used"; an encyclopedia is the first entry. The first publicly available description of HTML was a document called "HTML Tags", first mentioned on the Internet by Tim Berners-Lee in late 1991. It describes 18 elements comprising the initial, relatively simple design of HTML. Except for

10230-590: The religious instruction was most likely still provided on an individualistic basis. Takshashila is described in some detail in later Jātaka tales, written in Sri Lanka around the 5th century AD. It became a noted centre of learning at least several centuries BC, and continued to attract students until the destruction of the city in the 5th century AD. Takshashila is perhaps best known because of its association with Chanakya. The famous treatise Arthashastra ( Sanskrit for The knowledge of Economics ) by Chanakya,

10340-457: The school's funding in AD 529, a date that is often cited as the end of Antiquity . According to the sole witness, the historian Agathias , its remaining members looked for protection under the rule of Sassanid king Khosrau I in his capital at Ctesiphon , carrying with them precious scrolls of literature and philosophy, and to a lesser degree of science. After a peace treaty between the Persian and

10450-471: The semantic structure of the page, whereas < p > sections the page into paragraphs . The element < br /> is an empty element in that, although it may have attributes, it can take no content and it may not have an end tag. This is a link in HTML. To create a link the < a > tag is used. The href attribute holds the URL address of the link. There are many possible ways

10560-555: The short-lived Academia Secretorum Naturae of Naples, the first academy exclusively devoted to sciences was the Accademia dei Lincei founded in 1603 in Rome, particularly focused on natural sciences. In 1657 some students of Galileo founded the Accademia del Cimento (Academy of Experiment) in Florence , focused on physics and astronomy. The foundation of academy was funded by Prince Leopoldo and Grand Duke Ferdinando II de' Medici . This academy lasted after few decades. In 1652

10670-703: The spread of the Greek form of schools in the new Hellenistic cities built in Persia after the invasion of Alexander the Great . Under the Sasanians , Syriac became an important language of the administration and intellectuals, rivaling Greek. Several cities developed centers of higher learning in the Sasanian Empire, including Mosul , al-Hira , and Harran (famous for the Pythagorean School of

10780-607: The students of an academy-in-exile could have survived into the 9th century, long enough to facilitate the Arabic revival of the Neoplatonist commentary tradition in Baghdad . In ancient Greece, after the establishment of the original Academy, Plato 's colleagues and pupils developed spin-offs of his method. Arcesilaus , a Greek student of Plato established the Middle Academy . Carneades , another student, established

10890-517: The text between < body > and </ body > is the visible page content. The markup text < title > This is a title </ title > defines the browser page title shown on browser tabs and window titles and the tag < div > defines a division of the page used for easy styling. Between < head > and </ head > , a < meta > element can be used to define webpage metadata. The Document Type Declaration <!DOCTYPE html>

11000-416: The underlying macro language to develop custom macros such as new environments and commands. Such macros are often collected into packages, which could then be made available to address some specific typesetting needs such as the formatting of complex mathematical expressions or graphics (e.g., the use of the align environment provided by the amsmath package to produce aligned equations). To create

11110-431: The use of the term for these institutions. Gradually academies began to specialize on particular topics (arts, language, sciences) and began to be founded and funded by the kings and other sovereigns (few republics had an academy). And, mainly, since 17th century academies spread throughout Europe. In the 17th century the tradition of literary-philosophical academies, as circles of friends gathering around learned patrons,

11220-463: The word is typically given the unique capitalization LaTeX. Alternatively, the TeX, LaTeX and XeTeX logos can also be rendered via pure CSS and XHTML for use in graphical web browsers — by following the specifications of the internal \LaTeX macro. As a macro package, LaTeX provides a set of macros for TeX to interpret. There are many other macro packages for TeX, including Plain TeX, GNU Texinfo , AMSTeX , and ConTeXt . When TeX "compiles"

11330-419: The young Marsilio Ficino . Cosimo had been inspired by the arrival at the otherwise ineffective Council of Florence of Gemistos Plethon , who seemed a dazzling figure to the Florentine intellectuals. In 1462 Cosimo gave Ficino a villa at Careggi for the academy's use, situated where Cosimo could see it from his own villa, and drop by for visits. The academy remained a wholly informal group, but one which had

11440-517: Was a worshipper not merely of the literary and artistic form, but also of the ideas and spirit of classic paganism, which made him appear a condemner of Christianity and an enemy of the Church. In his academy every member assumed a classical name. Its principal members were humanists, like Bessarion's protégé Giovanni Antonio Campani (Campanus), Bartolomeo Platina , the papal librarian, and Filippo Buonaccorsi , and young visitors who received polish in

11550-445: Was an early centre of learning, near present-day Islamabad in the city of Taxila . It is considered one of the ancient universities of the world. According to scattered references which were only fixed a millennium later it may have dated back to at least the 5th century BC. Some scholars date Takshashila's existence back to the 6th century BC. The school consisted of several monasteries without large dormitories or lecture halls where

11660-475: Was continued in Italy; the " Umoristi " (1611), the " Fantastici (1625), and the " Ordinati ", founded by Cardinal Dati and Giulio Strozzi . About 1700 were founded the academies of the " Infecondi ", the " Occulti ", the " Deboli ", the " Aborigini ", the " Immobili ", the " Accademia Esquilina ", and others. During the 18th century many Italian cities established similar philosophical and scientific academies. In

11770-599: Was established in the 5th century AD in Bihar , India. It was founded in 427 in northeastern India, not far from what is today the southern border of Nepal. It survived until 1197 when it was set upon, destroyed and burnt by the marauding forces of Ikhtiyar Uddin Muhammad bin Bakhtiyar Khilji . It was devoted to Buddhist studies, but it also trained students in fine arts, medicine, mathematics, astronomy, politics and

11880-556: Was explained, at least as early as the beginning of the 6th century BC, by linking it to an Athenian hero , a legendary " Akademos ". The site of Akademia was sacred to Athena and other immortals. Plato's immediate successors as "scholarch" of Akademia were Speusippus (347–339 BC), Xenocrates (339–314 BC), Polemon (314–269 BC), Crates ( c.  269 –266 BC), and Arcesilaus ( c.  266 –240 BC). Later scholarchs include Lacydes of Cyrene , Carneades , Clitomachus , and Philo of Larissa ("the last undisputed head of

11990-689: Was founded the Academia Naturae Curiosorum by four physicians. In 1677, Leopold I , emperor of the Holy Roman Empire , recognised the society and in 1687 he gave it the epithet Leopoldina , with which is internationally famous. So, it became the academy of sciences for the whole Holy Roman Empire . On 28 November 1660, a group of scientists from and influenced by the Invisible College (gathering approximately since 1645) met at Gresham College and announced

12100-515: Was published in late 1999, with further errata published through 2001. In 2004, development began on HTML5 in the Web Hypertext Application Technology Working Group (WHATWG), which became a joint deliverable with the W3C in 2008, and was completed and standardized on 28 October 2014. XHTML is a separate language that began as a reformulation of HTML 4.01 using XML 1.0. It is now referred to as
