OneWebDay is an annual day of Internet celebration and awareness held on September 22. The stated goal of founder Susan P. Crawford is for OneWebDay to foster and make visible a global constituency that cares about the future of the Internet. The first OneWebDay was held on September 22, 2006. The idea was created by Susan P. Crawford, who was an ICANN board member at the time, in association with other Internet figures such as Doc Searls, David Weinberger, David R. Johnson, Mary Hodder, and David Isenberg, who would all join the board of what would eventually become a 501(c)3 corporation – OneWebDay Inc.

A website was established and a global network of events promoted. The 2006 OneWebDay’s celebration featured speakers Craig Newmark, Scott Heiferman, and Drew Schutte in New York City’s Battery Park.By 2008 OneWebDay had grown to more than 30 international events. In Washington Square Park, New York City, speakers included Crawford, John Perry Barlow, Jonathan Zittrain, Craig Newmark, and Lawrence Lessig. In 2009, Mitch Kapor took over chairmanship of OneWebDay. It was also announced that funding had been granted by the Ford Foundation.

In 2010, it was announced that OneWebDay would be combined with a new Mozilla Foundation year-round initiative called Drumbeat. A number of volunteers took over organizing the 2010 event. A new website and network was established. Events took place in several cities including New York City, Melbourne, Kolkata, Chennai, London, and Pachuca. In 2011, the main event was a presentation in New York City by Bob Frankston – “Infrastructure commons – the future of connectivity”. In 2012 the theme of OneWebDay was advancing local content while In 2013 the theme was accessibility, particularly in remembrance of web-accessibility advocate Cynthia Waddell, who died in April 2013.

In 2014 the theme for OneWebDay was Recognizing Core Internet Values, this included three videos: a TEDx talk by Dave Moskowitz, “The Internet Belongs to Everyone” from the United States State Department, and the Dynamic Coalition on Core Internet Values also gave a talk at the 2014 Internet Governance Forum. In 2015 and 2016 the theme was Connecting the Next Billion, During these events United States Under Secretary for Economic Growth, Energy and the Environment Catherine Novelli gave two speeches ‘Connecting The World’ at the USA-IGF. In 2017 the theme is Open The Pipes, which concerned the need for connectivity for Community Networks. For this event a speech was given by Internet Society CEO/President Kathy Brown at Mobile World Congress in Shanghai.


Autumn Equinox

The 2017 Autumn Equinox occurs in the Northern Hemisphere on 22 September and the Vernal Equinox occurs in the Southern Hemisphere. The equinox is the moment in which the plane of Earth’s equator passes through the center of the Sun’s disk, this occurs twice each year, around 20 March and 23 September. On an equinox, day and night are of approximately equal duration all over the planet. They are not exactly equal, however, due to the angular size of the sun and atmospheric refraction. The word is derived from the Latin aequinoctium, aequus (equal) and nox (genitive noctis) (night). The equinoxes are the only times when the solar terminator (the “edge” between night and day) is perpendicular to the equator. As a result, the northern and southern hemispheres are equally illuminated. The word comes from Latin equi or “equal” and nox meaning “night”.

The equinoxes are also the only times when the subsolar point is on the equator, meaning that the Sun is exactly overhead at a point on the equatorial line. The subsolar point crosses the equator moving northward at the March equinox and southward at the September equinox. The equinoxes, along with solstices, are directly related to the seasons of the year. In the northern hemisphere, the vernal equinox (March) conventionally marks the beginning of spring in most cultures and is considered the New Year in the Persian calendar or Iranian calendars as Nowruz (means new day), while the autumnal equinox (September) marks the beginning of autumn.

When Julius Caesar established the Julian calendar in 45 BC, he set 25 March as the date of the spring equinox. Because the Julian year is longer than the tropical year by about 11.3 minutes on average (or 1 day in 128 years), the calendar “drifted” with respect to the two equinoxes — such that in AD 300 the spring equinox occurred on about 21 March, and by AD 1500 it had drifted backwards to 11 March. This drift induced Pope Gregory XIII to create a modern Gregorian calendar. The Pope wanted to continue to conform with the edicts concerning the date of Easter of the Council of Nicaea of AD 325, which means he wanted to move the vernal equinox to the date on which it fell at that time (21 March is the day allocated to it in the Easter table of the Julian calendar). However, the leap year intervals in his calendar were not smooth (400 is not an exact multiple of 97). This causes the equinox to oscillate by about 53 hours around its mean position. This in turn raised the possibility that it could fall on 22 March, and thus Easter Day might theoretically commence before the equinox. The astronomers chose the appropriate number of days to omit so that the equinox would swing from 19 to 21 March but never fall on the 22nd (although it can in a handful of years fall early in the morning of that day in the Far East).

Day is usually defined as the period when sunlight reaches the ground in the absence of local obstacles. On the day of the equinox, the center of the Sun spends a roughly equal amount of time above and below the horizon at every location on the Earth, so night and day are about the same length. Sunrise and sunset can be defined in several ways, but a widespread definition is the time that the top limb of the sun is level with the horizon. With this definition, the day is longer than the night at the equinoxes. In sunrise/sunset tables, the assumed semidiameter (apparent radius) of the Sun is 16 minutes of arc and the atmospheric refraction is assumed to be 34 minutes of arc. Their combination means that when the upper limb of the Sun is on the visible horizon, its centre is 50 minutes of arc below the geometric horizon, which is the intersection with the celestial sphere of a horizontal plane through the eye of the observer. These effects make the day about 14 minutes longer than the night at the equator and longer still towards the poles. The real equality of day and night only happens in places far enough from the equator to have a seasonal difference in day length of at least 7 minutes, actually occurring a few days towards the winter side of each equinox.

The times of sunset and sunrise vary with the observer’s location (longitude and latitude), so the dates when day and night are equal also depend upon the observer’s location. At the equinoxes, the rate of change for the length of daylight and night-time is the greatest. At the poles, the equinox marks the transition from 24 hours of nighttime to 24 hours of daylight (or vice versa). The word equilux is sometimes (but rarely) used to mean a day in which the durations of light and darkness are equal. In the half-year centered on the June solstice, the Sun rises north of east and sets north of west, which means longer days with shorter nights for the northern hemisphere and shorter days with longer nights for the southern hemisphere. In the half-year centered on the December solstice, the Sun rises south of east and sets south of west and the durations of day and night are reversed. Also on the day of an equinox, the Sun rises everywhere on Earth (except at the poles) at about 06:00 and sets at about 18:00 (local solar time) however these times are not exact. The autumnal equinox is at ecliptic longitude 180° and at right ascension 12h.

The upper culmination of the vernal point is considered the start of the sidereal day for the observer. The hour angle of the vernal point is, by definition, the observer’s sidereal time. Using the current official IAU constellation boundaries – and taking into account the variable precession speed and the rotation of the celestial equator – the equinoxes shift through the constellations as follows (expressed in astronomical year numbering in which the year 0 = 1 BC, −1 = 2 BC, etc.). One effect of equinoctial periods is the temporary disruption of communications satellites. For all geostationary satellites, there are a few days around the equinox when the sun goes directly behind the satellite relative to Earth (i.e. within the beam-width of the ground-station antenna) for a short period each day. The Sun’s immense power and broad radiation spectrum overload the Earth station’s reception circuits with noise and, depending on antenna size and other factors, temporarily disrupt or degrade the circuit. The duration of those effects varies but can range from a few minutes to an hour. (For a given frequency band, a larger antenna has a narrower beam-width and hence experiences shorter duration “Sun outage” windows)

Michael Faraday

English Scientist Michael Faraday FRS was born 22 September 1791 in Newington Butts. The young Michael Faraday, received little formal education and had to educate himself.At fourteen he became the apprentice to George Riebau, a local bookbinder and bookseller in Blandford Street.During his seven-year apprenticeship he read many books, including Isaac Watts’ The Improvement of the Mind, and he enthusiastically implemented the principles and suggestions contained therein. At this time he also developed an interest in science, especially in electricity. Faraday was particularly inspired by the book Conversations on Chemistry by Jane Marcet.

In 1812, after his apprenticeship, Faraday attended lectures by the eminent English chemist Humphry Davy of the Royal Institution and Royal Society, and John Tatum, founder of the City Philosophical Society. Faraday subsequently sent Davy a three-hundred-page book based on notes that he had taken during these lectures. Davy’s reply was immediate, kind, and favourable. In 1813, Davy employed Faraday as Chemical Assistant at the Royal Institution on Very soon Davy entrusted Faraday with preparation of nitrogen trichloride samples, and they both became injured in an explosion of this very sensitive substance.

In the class-based English society of the time, Faraday was not considered a gentleman. When Davy set out on a long tour of the continent in 1813–15, his valet did not wish to go. Instead, Faraday went as Davy’s scientific assistant, and was asked to act as Davy’s valet until a replacement could be found in Paris. Faraday was forced to fill the role of valet as well as assistant throughout the trip Making Faraday so miserable that he contemplated giving up science altogether. The trip did, however, give him access to the scientific elite of Europe and exposed him to a host of stimulating ideas

Faraday married Sarah Barnard They met through their families at the Sandemanian church, and he confessed his faith to the Sandemanian congregation the month after they were married. They had no children. Faraday was a devout Christian; his Sandemanian denomination was an offshoot of the Church of Scotland. Well after his marriage, he served as deacon and for two terms as an elder in the meeting house of his youth. His church was located at Paul’s Alley in the Barbican. This meeting house was relocated in 1862 to Barnsbury Grove, Islington; this North London location was where Faraday served the final two years of his second term as elder prior to his resignation from that post. Biographers have noted that “a strong sense of the unity of God and nature pervaded Faraday’s life and work.”

In June 1832, the University of Oxford granted Faraday a Doctor of Civil Law degree (honorary). During his lifetime, he was offered a knighthood in recognition for his services to science. He twice refused to become President of the Royal Society. He was elected a foreign member of the Royal Swedish Academy of Sciences in 1838, and was one of eight foreign members elected to the French Academy of Sciences in 1844. In 1849 he was elected as associated member to the Royal Institute of the Netherlands, which two years later became the Royal Netherlands Academy of Arts and Sciences and he was subsequently made foreign member. Faraday suffered a nervous breakdown in 1839 but eventually returned to his electromagnetic investigations. In 1848, as a result of representations by the Prince Consort, Faraday was awarded a grace and favour house in Hampton Court. When asked by the British government to advise on the production of chemical weapons for use in the Crimean War (1853–1856), Faraday refused to participate citing ethical reasons. Faraday died at his house at Hampton Court on 25 August 1867, aged 75. He had previously turned down burial in Westminster Abbey, but he has a memorial plaque there, near Isaac Newton’s tomb. Faraday was interred in the dissenters’ (non-Anglican) section of Highgate Cemetery.

Faraday was one of the most influential scientists in history. He contributed to the fields of electromagnetism and electrochemistry. His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis.It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the basis for the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. He similarly discovered the principle of electromagnetic induction, diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became practical for use in technology.

As a chemist, Faraday discovered benzene, investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers, and popularised terminology such as anode, cathode, electrode, and ion. Faraday ultimately became the first and foremost Fullerian Professor of Chemistry at the Royal Institution of Great Britain, a lifetime position. Albert Einstein kept a picture of Faraday on his study wall, alongside pictures of Isaac Newton and James Clerk Maxwell. Physicist Ernest Rutherford stated; “When we consider the magnitude and extent of his discoveries and their influence on the progress of science and of industry, there is no honour too great to pay to the memory of Faraday, one of the greatest scientific discoverers of all time”.

World Water Monitoring day

World Water Monitoring Day takes place annully on 18 September. It was established in 2003 by America’s Clean Water Foundation as a global educational outreach program that aims to build public awareness and involvement in protecting water resources around the world by empowering citizens to carry out basic monitoring of their local water bodies. Roberta (Robbi) Savage, ACWF’s President and CEO created WWMD and Edward Moyer was the first WWMD Coordinator. It was initially chosen to be a month later (October 18) to recognize the anniversary of the US Clean Water Act, which was enacted by the US Congress in 1972 to restore and protect the country’s water resources.

However In 2007, the date was changed to enable participation in parts of the world where temperatures reach freezing at that time. In 2006, ACWF transferred coordination of the event to the Water Environment Federation (WEF) and the International Water Association (IWA). The collective goal was to expand participation to one million people in 100 countries by 2012. In January 2015 the management of World Water Monitoring Day was again transferred – this time to Phillipe Cousteau’s educational non-profit EarthEcho International.

In 2008 students from Indonesia to Arkansas took part in water sampling to bring attention to the importance of water quality by means of a A simple test kit which enables participants, to sample local water bodies for a set of water quality parameters including temperature, acidity (pH), clarity (turbidity) and dissolved oxygen (DO). Results are then shared with participating communities around the globe through the WWMC website.

World Lymphoma Awareness Day

World Lymphoma Awareness Day (WLAD) is a global initiative held annually on September 15 with the aim of raising awareness of lymphoma, an increasingly common form of cancer. It is hosted by the Lymphoma Coalition (LC), a non-profit network organisation of 63 lymphoma patient groups from 44 countries around the world.

WLAD was initiated in 2004 to raise public awareness of both Hodgkin and non- Hodgkin lymphoma in terms of symptom recognition, early diagnosis and treatment. Lymphoma is a potentially life threatening disease which is becoming more widespread Currently One million people worldwide live with lymphoma with nearly 1,000 people being diagnosed with the disease every day, and World Lymphoma Awareness Day aims to raise awareness of the signs and symptoms of lymphoma, to fund lymphoma research and to allow people around the world to better recognize its signs and symptoms, leading to earlier diagnosis and more timely treatment. Greater awareness will also empower patients and their families to demand specialist treatment and care from qualified lymphoma physicians as well as gain access to the most up-to-date information, support and treatment.This global campaign aims to provide a platform for doctors, nurses, patient support groups, patients and their families to share vital knowledge about lymphoma, its signs and symptoms, and how it affects lives of thousands of people around the world.

Know Your Nodes is a public awareness campaign launched by the World Lymphoma Awareness Day in 2007, to enable people to learn more about their lymph nodes, lymphatic systems and the signs and symptoms of lymphoma in time for World Lymphoma Awareness Day. Lymphoma’s signs and symptoms can be similar to other, less serious illnesses, and increasing awareness of lymphoma will allow people around the world to better recognise its signs and symptoms, leading to earlier diagnosis and more timely treatment.

The Beacons of Hope program was created in 2006 to celebrate inspiring people around the world that have been affected by lymphoma. Lymphoma Coalition members were asked to nominate individuals affected by lymphoma who acted as global ‘Beacons of Hope’ ambassadors. The ambassadors spread the word of hope across the world, bringing real life experience to WLAD. The Lymphoma Club was founded in 2010 to recognize those affected by all Lymphomas (Hodgkin’s and Non-Hodgkin’s Lymphoma) and to help raise awareness for Lymphoma. The Lymphoma Coalition is a non-profit network organisation of lymphoma patient groups which was Established in 2003, with the aim of raising awareness of lymphoma, and promoting the well-being of people affected by lymphoma worldwide.

Isambard Kingdom Brunel

Best known for building dockyards, the Great Western Railway, steamships, bridges, tunnels and revolutionising public transport and modern engineering, the British mechanical and Civil Engineer Isambard Kingdom Brunel, FRS sadly died 15  Spetember 1859 after having a Stroke. He was born 9 April 1806. When Brunel was eight he was sent to Dr Morrell’s boarding school in Hove, where he learned the classics. His father, was determined that Brunel should have access to the high-quality education he had enjoyed in his youth in France; accordingly, at the age of 14, the younger Brunel was enrolled first at the College of Caen in Normandy, then at Lycée Henri-Quatre in Paris. Sadly his because his Father Marc sent him to expensive schools, he encountered financial problems, however because he was a Prominent engineer the Government intervened on his behalf.When Brunel completed his studies at Henri-Quatre in 1822, he was due to attend the renowned engineering school École Polytechnique, however Brunel studied under the prominent master clockmaker and horologist Abraham-Louis Breguet instead, after he praised Brunel’s potential in letters to his father.In late 1822, having completed his apprenticeship, Brunel returned to England. Brunel worked for several years as an assistant engineer on the hazardous project to create a tunnel under London’s River Thames near Rotherhithe, alongside his Father, who was chief engineer. However cave-ins and severe flooding in 1828 killed a number of Miners a delayed work, with Brunel narrowly escaping death himself.

During Brunel’s life, the use of railways began to take off as a major means of transport for goods. This influenced Brunel’s involvement in railway engineering, including railway bridge engineering. In 1833, before the Thames Tunnel was complete, Brunel was appointed chief engineer of the Great Western Railway, one of the wonders of Victorian Britain, running from London to Bristol and later Exeter.The company was founded at a public meeting in Bristol in 1833, and was incorporated by Act of Parliament in 1835. It was Brunel’s vision that passengers would be able to purchase one ticket at London Paddington and travel from London to New York, changing from the Great Western Railway to the Great Western steamship at the terminus in Neyland, South Wales.He surveyed the entire length of the route between London and Bristol himself, with the help of many including his Solicitor Jeremiah Osborne of Bristol Law Firm Osborne Clarke who one occasion rowed Isambard Kingdom Brunel down the River Avon himself to survey the bank of the river for the route.

Brunel used broad gauge of 7 ft 1⁄4 in (2,140 mm) for the track, despite almost all other railways using standard Gauge, because he believed Standard Gauge would offer superior running at high speeds; he also proved through both calculation and a series of trials that his broader gauge was the optimum size for providing both higher speeds, greater stability, comfort for passengers, and allowed for larger carriages and thus greater freight capacity. Drawing on Brunel’s experience with the Thames Tunnel, the Great Western designed many viaducts such as the one in Ivybridge, specially designed stations, and vast tunnels including the Box Tunnel, which was the longest railway tunnel in the world at that time. Brunel also ordered many Locomotives to his own specification including “North Star” and 20-year-old Daniel Gooch (later Sir Daniel) was appointed as Superintendent of Locomotive Engines. Brunel and Gooch chose to locate their locomotive works at the village of Swindon.

Brunel also designed many bridges including the Clifton Suspension Bridge in Bristol. Spanning over 700 ft (210 m), and nominally 200 ft (61 m) above the River Avon, after submitting his designs to a committee headed by Thomas Telford, who rejected all entries, in favour of his own design, until the Public voted in favour of Brunel’s design. Brunel also designed the Maidenhead Railway Bridge. Work also started on the Clifton suspension bridge in 1831, but was suspended due to the Queen Square Riots, However Thanks to colleagues at the Institute of Civil Engineers Work recommenced in 1862 and was completed in 1864, five years after Brunel’s death. The Clifton Suspension Bridge still stands today and over 4 million vehicles traverse it every year.

Brunel also designed the Royal Albert Bridge spanning the River Tamar at Saltash near Plymouth, Somerset Bridge (an unusual laminated timber-framed bridge near Bridgwater, the Windsor Railway Bridge. The Maidenhead Railway Bridge over the Thames in Berkshire is still carrying main line trains to the west, even though today’s trains are about ten times heavier than in Brunel’s time.In 1845 Hungerford Bridge, a suspension footbridge across the Thames near Charing Cross Station in London, was opened. It was replaced by a new railway bridge in 1859, and the suspension chains were used to complete the Clifton Suspension Bridge. Brunel also designed the Royal Albert Bridge in 1855 for the Cornwall Railway, this consists of two main spans of 455 ft (139 m), 100 ft (30 m) above mean high spring tide, plus 17 much shorter approach spans. Opened by Prince Albert on 2 May 1859, it was completed in the year of Brunel’s death.

In 1830, he was elected a Fellow of the Royal Society and On 5 July 1836, Brunel married Mary Elizabeth Horsley (b. 1813), who came from an accomplished musical and artistic family, being the eldest daughter of composer and organist William Horsley. They established a home at Duke Street, Westminster, in London. In 1843, while performing a conjuring trick for the amusement of his children, Brunel accidentally inhaled a half-sovereign coin, which became lodged in his windpipe. A special pair of forceps failed to remove it, as did a machine devised by Brunel to shake it loose. At the suggestion of his father, Brunel was strapped to a board and turned upside-down, and the coin was jerked free. He recuperated at Teignmouth, and enjoyed the area so much that he purchased an estate at Watcombe in Torquay, Devon. Here he designed Brunel Manor and its gardens to be his retirement home. Sadly He never saw the house or gardens finished, as he died before it was completed. Brunel, a heavy smoker, suffered a stroke Just before the Great Eastern made her first voyage to New York. He died ten days later at the age of 53 and was buried, like his father, in Kensal Green Cemetery in London.He left behind his wife Mary and three children: Isambard Brunel Junior (1837–1902), Henry Marc Brunel (1842–1903) and Florence Mary Brunel (1847–1876). Henry Marc followed his father and grandfather in becoming a successful civil engineer.

World Wide Web

The World Wide Web (abbreviated as WWW or W3, commonly known as the web)debuted on 23 August 1991. The World Wide Web is asystem of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them via hyperlinks.The web was developed between March 1989 and December 1990. Using concepts from his earlier hypertext systems such as ENQUIRE, British engineer Tim Berners-Lee, acomputer scientist and at that time employee of the CERN, now Director of the World Wide Web Consortium (W3C), wrote a proposal in March 1989 for what would eventually become the World Wide Web. The 1989 proposal was meant for a more effective CERN communication system but Berners-Lee eventually realised the concept could be implemented throughout the world. At CERN, a European research organisation nearGeneva straddling the border between France and Switzerland, berners-Lee and Belgian computer scientist Robert Cailliau proposed in 1990 to use hypertext “to link and access information of various kinds as a web of nodes in which the user can browse at will”, and Berners-Lee finished the first website in December that year. Berners-Lee posted the project on the alt.hypertext newsgroup on 7 August 1991

In the May 1970 issue of Popular Science magazine, Arthur C. Clarke predicted that satellites would someday “bring the accumulated knowledge of the world to your fingertips” using a console that would combine the functionality of the photocopier, telephone, television and a small computer, allowing data tyransfer and video conferencing around the globe.In March 1989, Tim Berners-Lee wrote a proposal that referenced ENQUIRE, a database and software project he had built in 1980, and described a more elaborate information management system. With help from Robert Cailliau, he published a more formal proposal (on 12 November 1990) to build a “Hypertext project” called “WorldWideWeb” (one word, also “W3″) as a “web” of “hypertext documents” to be viewed by “browsers” using a client–server architecture. This proposal estimated that a read-only web would be developed within three months and that it would take six months to achieve “the creation of new links and new material by readers, [so that] authorship becomes universal” as well as “the automatic notification of a reader when new material of interest to him/her has become available.” While the read-only goal was met, accessible authorship of web content took longer to mature, with the wiki concept, blogs, Web 2.0 and RSS/Atom.

The proposal was modeled after the SGML reader Dynatext by Electronic Book Technology, a spin-off from the Institute for Research in Information and Scholarship at Brown University. The Dynatext system, licensed by CERN, was a key player in the extension of SGML ISO 8879:1986 to Hypermedia within HyTime, but it was considered too expensive and had an inappropriate licensing policy for use in the general high energy physics community, namely a fee for each document and each document alteration.The CERN datacenter in 2010 housing some WWW serversA NeXT Computer was used by Berners-Lee as the world’s first web server and also to write the first web browser, WorldWideWeb, in 1990. By Christmas 1990, Berners-Lee had built all the tools necessary for a working Web: the first web browser (which was a web editor as well); the first web server; and the first web pages, which described the project itself.The first web page may be lost, but Paul Jones of UNC-Chapel Hill in North Carolina revealed in May 2013 that he has a copy of a page sent to him by Berners-Lee which is the oldest known web page. Jones stored it on a floppy disk and on his NeXT computer.

On 6 August 1991, Berners-Lee posted a short summary of the World Wide Web project on the alt.hypertext newsgroup. This date also marked the debut of the Web as a publicly available service on the Internet, although new users only access it after August 23. For this reason this is considered the internaut’s day. Many newsmedia have reported that the first photo on the web was uploaded by Berners-Lee in 1992, an image of the CERN house band Les Horribles Cernettes taken by Silvano de Gennaro; Gennaro has disclaimed this story, writing that media were “totally distorting our words for the sake of cheap sensationalism.” The first server outside Europe was set up at the Stanford Linear Accelerator Center (SLAC) in Palo Alto, California, to host the SPIRES-HEP database. Accounts differ substantially as to the date of this event. The World Wide Web Consortium says December 1992, whereas SLAC itself claims 1991. This is supported by a W3C document titled A Little History of the World Wide Web. The crucial underlying concept of hypertext originated with older projects from the 1960s, such as the Hypertext Editing System (HES) at Brown University, Ted Nelson’s Project Xanadu, and Douglas Engelbart’s oN-Line System (NLS). Both Nelson and Engelbart were in turn inspired by Vannevar Bush’s microfilm-based “memex”, which was described in the 1945 essay “As We May Think”.

Berners-Lee’s breakthrough was to marry hypertext to the Internet. In his book Weaving The Web, he explains that he had repeatedly suggested that a marriage between the two technologies was possible to members of both technical communities, but when no one took up his invitation, he finally assumed the project himself. In the process, he developed three essential technologies:a system of globally unique identifiers for resources on the Web and elsewhere, the universal document identifier (UDI), later known as uniform resource locator (URL) and uniform resource identifier (URI);the publishing language HyperText Markup Language (HTML);the Hypertext Transfer Protocol (HTTP). The World Wide Web had a number of differences from other hypertext systems available at the time. The web required only unidirectional links rather than bidirectional ones, making it possible for someone to link to another resource without action by the owner of that resource. It also significantly reduced the difficulty of implementing web servers and browsers (in comparison to earlier systems), but in turn presented the chronic problem of link rot. Unlike predecessors such as HyperCard, the World Wide Web was non-proprietary, making it possible to develop servers and clients independently and to add extensions without licensing restrictions. On 30 April 1993, CERN announced that the World Wide Web would be free to anyone, with no fees due. Coming two months after the announcement that the server implementation of the Gopher protocol was no longer free to use, this produced a rapid shift away from Gopher and towards the Web.

An early popular web browser was ViolaWWW for Unix and the X Windowing System..Scholars generally agree that a turning point for the World Wide Web began with the introduction of the Mosaic web browser in 1993, a graphical browser developed by a team at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign (NCSA-UIUC), led by Marc Andreessen. Funding for Mosaic came from the U.S. High-Performance Computing and Communications Initiative and the High Performance Computing and Communication Act of 1991, one of several computing developments initiated by U.S. Senator Al Gore. Prior to the release of Mosaic, graphics were not commonly mixed with text in web pages and the web’s popularity was less than older protocols in use over the Internet, such as Gopher and Wide Area Information Servers(WAIS). Mosaic’s graphical user interface allowed the Web to become, by far, the most popular Internet protocol.

After leaving the European Organization for Nuclear Research (CERN) In 1994, Tim Berners Lee founded The World Wide Web Consortium (W3C) at the theMassachusetts Institute of Technology Laboratory for Computer Science (MIT/LCS) with support from the Defense Advanced Research Projects Agencyw (DARPA), which had pioneered the Internet. A year later, a second site was founded at INRIA (a French national computer research lab) with support from the European Commission DG InfSo; and in 1996, a third continental site was created in Japan at Keio University. By the end of 1994, while the total number of websites was still minute compared to present standards, quite a number of notable websites were already active, many of which are the precursors or inspiration for today’s most popular services.Connected by the existing Internet, other websites were created around the world, adding international standards for domain names and HTML. Since then, Berners-Lee has played an active role in guiding the development of web standards (such as the markup languages in which web pages are composed), and has advocated his vision of a Semantic Web. The World Wide Web enabled the spread of information over the Internet through an easy-to-use and flexible format. It thus played an important role in popularizing use of the Internet. Although the two terms are sometimes conflated in popular use, World Wide Web is not synonymous with Internet. The web is a collection of documents and both client and server software using Internet protocols such as TCP/IP and HTTP. Tim Berners-Lee was knighted in 2004 by Queen Elizabeth II for his contribution to the World Wide Web.
