Edward Davy

English physician, scientist, and inventor Edward Davy was born 16 june 1806, he played a prominent role in the development of telegraphy, and invented an electric relay. Davy was born in Ottery St Mary, Devonshire, England and was educated at a school run by his maternal uncle in Tower Street, London. He was then apprenticed to Dr Wheeler, house surgeon at St Bartholomew’s Hospital. Davy won the prize for botany in 1825, was licensed by the Worshipful Society of Apothecaries in 1828 and the Royal College of Surgeons in 1829. Soon after graduating, Davy began trading as an operative chemist under the name of Davy & Co. In 1836 he published a small book Experimental Guide to Chemistry, at the end of which was a catalogue of goods supplied by his firm.

Davy published Outline of a New Plan of Telegraphic Communication in 1836 and carried out telegraphic experiments the following year. He demonstrated the operation of the telegraph over a mile of wire in Regent’s Park. In 1837 he demonstrated a working model of the telegraph in Exeter Hall. He was granted a patent for his telegraph in 1838. However, he was soon obliged to drop his investigations of telegraphy for personal reasons. His patent was purchased by the Electric Telegraph Company in 1847 for £600. Davey also invented an electric relay. He used a magnetic needle which dipped into a mercury contact when an electric current passed through the surrounding coil.

In recognition of his work he was elected in 1885 as an honorary member of the Society of Telegraph Engineers and was informed of this by telegraph shortly before his death. In 1838 Davy migrated to South Australia without his first wife and son. He became editor of the Adelaide Examiner from June to July 1842 and was elected president of the Port Adelaide Mechanics’ Institute at its inaugural meeting in 1851. Davy was also a director and manager of the Adelaide Smelting Company and became chief assayer of the Government Assay Office in Adelaide in February 1852. Davy was also appointed assay master in Melbourne in July 1853 until the office was abolished in October 1854. For a short while, he took up farming near Malmsbury, Victoria then moved into Malmsbury where he practised as a physician for the rest of his life. He was three times mayor of Malmbury. Davy sadly passed away 26 January 1885

Jacques Cousteau

The late great pioneering French naval oficer, explorer conservationist, filmmaker, innovator, scientist, photographer, author and researcher Jacques-Yves Cousteau was born 11 June 1910. He studied the sea and aquatic life And co-developed the Aqua-Lung. He was also a member of the Académie Français and studied at the Collège Stanislas in Paris. In 1930, he entered the École Navale and graduated as a gunnery officer. After a car accident cut short his career in naval aviation, Cousteau indulged his interest in the sea.In Toulon, where he was serving on the Condorcet, Cousteau carried out his first underwater experiments, thanks to his friend Philippe Tailliez who in 1936 lent him some Fernez underwater goggles. Cousteau also worked for the information service of the French Navy, and was sent on missions to Shanghai and Japan (1935–1938) and in the USSR in 1939.

After the armistice of 1940, his family took refuge in Megève, where he became a friend of the Ichac family who also lived there. Jacques-Yves Cousteau and Marcel Ichac shared the same desire to reveal to the general public unknown and inaccessible places — for Cousteau the underwater world and for Ichac the high mountains. The to neighbors took the first ex-aequo prize of the Congress of Documentary Film in 1943, for the first French underwater film: Par dix-huit mètres de fond (18 meters deep), made without breathing apparatus the previous year in the Embiez islands with Philippe Tailliez and Frédéric Dumas, using a depth-pressure-proof camera case developed by mechanical engineer Léon Vèche (engineer of Arts and Métiers and the Naval College). In 1943, they made the film Épaves (Shipwrecks), in which they used two of the very first Aqua-Lung prototypes. These prototypes were made in Boulogne-Billancourt by the Air Liquide company, following instructions from Cousteau and Émile. Having kept bonds with the English speakers (he spent part of his childhood in the United States and usually spoke English) and with French soldiers in North Africa ( Jacques-Yves Cousteau , helped the French Navy to join again with the Allies and assembled a commando operation against the Italian espionage services in France, for which he received several military decorations for his deeds. At that time, he kept his distance from his brother Pierre-Antoine Cousteau, a “pen anti-semite” who wrote the collaborationist newspaper Je suis partout (I am everywhere) and who received the death sentence in 1946. However, this was later commuted to a life sentence, and Pierre-Antoine was released in 1954.

During the 1940s, Cousteau worked on the aqua-lung design the forerunner of open-circuit scuba technology used today. Cousteau started diving with Fernez goggles in 1936, and in 1939 used the self-contained underwater breathing apparatus invented in 1926 by Commander Yves le Prieur but dissatisfied with its performance so he improved it to extend underwater duration by adding a demand regulator, invented in 1942 by Émile Gagnan. In 1943 Cousteau tried out the first prototype aqua-lung which made extended underwater exploration possible. In 1946, Cousteau and Tailliez showed the film “Épaves”and set up the Groupement de Recherches Sous-marines (GRS) (Underwater Research Group) of the French Navy in Toulon. A little later it became the GERS (Groupe d’Études et de Recherches Sous-Marines, = Underwater Studies and Research Group), then the COMISMER (“COMmandement des Interventions Sous la MER”, = “Undersea Interventions Command”), and finally more recently the CEPHISMER. In 1947, Chief Petty Officer Maurice Fargues became the first diver to die using an aqualung while attempting a new depth record with the GERS near Toulon.

In 1948, between missions of mine clearance, underwater exploration and technological and physiological tests, Cousteau undertook a first campaign in the Mediterranean on board the sloop Élie Monnier, with Philippe Tailliez, Frédéric Dumas, Jean Alinat and the scenario writer Marcel Ichac. The small team also undertook the exploration of the Roman wreck of Mahdia (Tunisia). It was the first underwater archaeology operation using autonomous diving, opening the way for scientific underwater archaeology. Cousteau and Marcel Ichac brought back from there the Carnets diving film (presented and preceded with the Cannes Film Festival 1951).Cousteau and the Élie Monnier then took part in the rescue of Professor Jacques Piccard’s bathyscaphe, the FNRS-2, during the 1949 expedition to Dakar. Thanks to this rescue, the French Navy was able to reuse the sphere of the bathyscaphe to construct the FNRS-3.The adventures of this period are told in the two books The Silent World (1953, by Cousteau and Dumas) and Plongées sans câble(1954, by Philippe Tailliez)

.In 1949, Cousteau left the French Navy.In 1950, he founded the French Oceanographic Campaigns (FOC), and leased a ship called Calypso from Thomas Loel Guinness for a symbolic one franc a year. Cousteau refitted the Calypso as a mobile laboratory for field research and as his principal vessel for diving and filming. He also carried out underwater archaeological excavations in the Mediterranean, in particular at Grand-Congloué (1952).With the publication of his first book in 1953, The Silent World, he correctly predicted the existence of the echolocation abilities ofporpoises. He reported that his research vessel, the Élie Monier, was heading to the Straits of Gibraltar and noticed a group of porpoises following them. Cousteau changed course a few degrees off the optimal course to the center of the strait, and the porpoises followed for a few minutes, then diverged toward mid-channel again. It was evident that they knew where the optimal course lay, even if the humans did not. Cousteau concluded that the cetaceans had something like sonar, which was a relatively new feature on submarines.

Cousteau won the Palme d’Or at the Cannes Film Festival in 1956 for The Silent World co-produced with Louis Malle. With the assistance of Jean Mollard, he made a “diving saucer” SP-350, an experimental underwater vehicle which could reach a depth of 350 meters. The successful experiment was quickly repeated in 1965 with two vehicles which reached 500 meters.In 1957, he was elected as director of the Oceanographical Museum of Monaco. He directed Précontinent, about the experiments of diving in saturation (long-duration immersion, houses under the sea), and was admitted to the United States National Academy of Sciences.He was involved in the creation of Confédération Mondiale des Activités Subaquatiques and served as its inaugural president from 1959 to 1973. In October 1960, a large amount of radioactive waste was going to be discarded in the Mediterranean Sea by the Commissariat à l’énergie atomique (CEA). The CEA argued that the dumps were experimental in nature, and that French oceanographers such asVsevelod Romanovsky had recommended it. Romanovsky and other French scientists, including Louis Fage and Jacques Cousteau, repudiated the claim, saying that Romanovsky had in mind a much smaller amount. The CEA claimed that there was little circulation (and hence little need for concern) at the dump site between Nice and Corsica, but French public opinion sided with the oceanographers rather than with the CEA atomic energy scientists. The CEA chief, Francis Perrin, decided to postpone the dump. Cousteau organized a publicity campaign which in less than two weeks gained wide popular support. The train carrying the waste was stopped by women and children sitting on the railway tracks, and it was sent back to its origin.

A meeting with American television companies (ABC, Métromédia, NBC) created the series The Undersea World of Jacques Cousteau, with the character of the commander in the red bonnet inherited from standard diving dress) intended to give the films a “personalized adventure” style. This documentary television series ran for ten years from 1966 to 1976. A second documentary series, The Cousteau Odyssey, ran from 1977 to 1982, among others.In 1970, he wrote the book The Shark: Splendid Savage of the Sea with Philippe, his son. In this book, Costeau described the oceanic whitetip shark as “the most dangerous of all sharks”.In 1973, along with his two sons and Frederick Hyman, he created the Cousteau Society for the Protection of Ocean Life, Frederick Hyman being its first President; it now has more than 300,000 members.On December 1975, two years after the volcano’s last eruption, The Cousteau Society was filming Voyage au bout du monde on Deception Island, Antarctica, when Michel Laval, Calypso’s second in command, was struck and killed by a propeller of the helicopter that was ferrying between Calypso and the island.

In1976, Cousteau uncovered the wreck of HMHS Britannic. He also found the wreck of the French 17th-century ship-of-the-line La Therese in coastal waters of Crete.In 1977, together with Peter Scott, he received the UN International Environment prize.On 28 June 1979, while the Calypso was on an expedition to Portugal, his second son, Philippe, his preferred and designated successor and with whom he had co-produced all his films since 1969, died in a PBY Catalina flying boat crash in the Tagus river near Lisbon. Cousteau was deeply affected. He called his then eldest son, the architect Jean-Michel Cousteau, to his side. This collaboration lasted 14 years.In 1975 John Denver released the tribute song “Calypso” on his album “Windsong”, and on the B-side of his hit song “I’m Sorry”. “Calypso” became a hit on its own and was later considered the new A-side, reaching #2 on the charts.

From 1980 to 1981, he was a regular on the animal reality show Those Amazing Animals, along with Burgess Meredith, Priscilla Presley, and Jim Stafford. In 1980, Cousteau traveled to Canada to make two films on the Saint Lawrence River and the Great Lakes, Cries from the Deep and St. Lawrence: Stairway to the Sea. In 1985, he received the Presidential Medal of Freedom from Ronald Reagan.On 24 November 1988, he was elected to the Académie française, chair 17, succeeding Jean Delay. His official reception under the Cupola took place on 22 June 1989, the response to his speech of reception being given by Bertrand Poirot-Delpech. After his death, he was replaced under the Cupola by Érik Orsenna on 28 May 1998.In June 1990, the composer Jean Michel Jarre paid homage to the commander by entitling his new album Waiting for Cousteau. He also composed the music for Cousteau’s documentary “Palawan, the last refuge” .

On 2 December 1990, his wife Simone Cousteau died of cancer .In June 1991, Jacques-Yves Cousteau remarried, to Francine Triplet, with whom he had (before this marriage) two children, Diane and Pierre-Yves. Francine Cousteau currently continues her husband’s work as the head of the Cousteau Foundation and Cousteau Society. From that point, the relations between Jacques-Yves and his elder son worsened. In November 1991, Cousteau gave an interview to the UNESCO Courier, in which he stated that he was in favour of human population control and population decrease and in 1992, he was invited to Rio de Janeiro, Brazil, for the United Nations’ International Conference on Environment and Development, and then he became a regular consultant for the UN and the World Bank. In 1996, he sued his son who wished to open a holiday centre named “Cousteau” in the Fiji Islands. On 11 January 1996, Calypso was rammed and sunk in Singapore Harbour by a barge. The Calypso was refloated and towed home to France. Jacques-Yves Cousteau sadly passed away after a heart attack on 25 June 1997 in Paris, aged 87, and was buried in a Roman Catholic Christian funeral in the family vault at Saint-André-de-f in France. A street was renamed “rue du Commandant Cousteau”, in his honour and a commemorative plaque was affixed to his house.


English-American computer scientist and engineer, Sir Timothy John Berners-Lee OM KBE FRS FREng FRSA FBCS was was born 8 June 1955 In London, England. His parents Mary Lee Woods and Conway Berners-Lee worked on the first commercially-built computer, the Ferranti Mark 1. He attended Sheen Mount Primary School, and then went on to attend south west London’s Emanuel School from 1969 to 1973, at the time a direct grant grammar school, which became an independent school in 1975. A keen trainspotter as a child, he learnt about electronics from tinkering with a model railway. He studied at The Queen’s College, Oxford from 1973 to 1976, where he received a first-class degree bachelor of arts degree in physics.

After graduation, Berners-Lee worked as an engineer at the telecommunications company Plessey in Poole, Dorset. In 1978, he joined D. G. Nash in Ferndown, Dorset, where he helped create type-setting software for printers. Berners-Lee worked as an independent contractor at CERN from June to December 1980. While in Geneva, he proposed a project based on the concept of hypertext, to facilitate sharing and updating information among researchers. To demonstrate it, he built a prototype system named ENQUIRE. After leaving CERN in late 1980, he went to work at John Poole’s Image Computer Systems, Ltd, in Bournemouth, Dorset. He ran the company’s technical side for three years. The project he worked on was a “real-time remote procedure call” which gave him experience in computer networking. In 1984, he returned to CERN as a fellow. In 1989, CERN was the largest Internet node in Europe, and Berners-Lee saw an opportunity to join hypertext with the Internet:

I just had to take the hypertext idea and connect it to the Transmission Control Protocol and domain name system ideas and—ta-da!—the World Wide Web. Creating the web was really an act of desperation, because the situation without it was very difficult when I was working at CERN. Most of the technology involved in the web, like the hypertext, like the Internet, multifont text objects, had all been designed already. I just had to put them together. It was a step of generalising, going to a higher level of abstraction, thinking about all the documentation systems out there as being possibly part of a larger imaginary documentation system.” This NeXT Computer was used by Berners-Lee at CERN and became the world’s first web server. Berners-Lee wrote his proposal in March 1989 and, in 1990, redistributed it. He used similar ideas to those underlying the ENQUIRE system to create the World Wide Web, for which he designed and built the first Web browser. His software also functioned as an editor (called WorldWideWeb, running on the NeXTSTEP operating system), and the first Web server, CERN HTTPd (short for Hypertext Transfer Protocol daemon).

He is commonly credited with inventing the World Wide Web (abbreviated as WWW or W3, commonly known as the web). The World Wide Web is a series 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”. Berners-Lee finished the first website in December 1990 and 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.”[18]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,[19]whereas SLAC itself claims 1991. This is supported by a W3C document titled A Little History of the World Wide Web.[22]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.[28] 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.

The World Wide Web Consortium (W3C) was founded by Tim Berners-Lee after he left the European Organization for Nuclear Research (CERN) in October 1994. It was founded at theMassachusetts Institute of Technology Laboratory for Computer Science (MIT/LCS) with support from the Defense Advanced Research Projects Agency (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 namesand 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.

Alan Turing OBE FRS

British mathematician, logician, cryptanalyst, and computer scientist Alan Turing OBE, FRS was found dead 8 June 1954 after committing suicide. He was Born on June 23rd, 1912 in Maida Vale, and grew up in Hastings. He displayed great individuality from a young age. At 14 he went to Sherborne School in Dorset.Turing subsequently read mathematics at Cambridge,He was completely original thinkerwho shaped the modern world, and assisted in the development of the innovative Manchester computers. He was also highly influential in the development of computer science, providing a formalisation of the concepts of “algorithm” and “computation” with the Turing machine, which played a sinificant role in the creation of the modern computer. Turing is widely considered to be the father of computer science and artificial intelligece.He also became interested in mathematical biology and wrote a paper on the chemical basis of morphogenesis, and predicted oscillating chemical reactions such as the Belousov–Zhabotinsky reaction, which were first observed in the 1960s.

On 4 September 1939 the day after Britain declared war on Germany, Turing reported to Bletchley Park where he worked for the Government Code and Cypher School (GCCS)the forerunner of GCHQ, Britain’s codebreaking centre. For a time he was head of Hut 8, the section responsible for German naval cryptanalysis. Turing led a team whose ingenuity and intellect were turned to the task of breaking German ciphers. He devised a number of techniques for breaking German ciphers and One of Turing’s main contributions whilst there was to invent the Bombe, an electromechanical machine used to find the daily settings of the Enigma machine. as a result he played an absolutely vital part of the British war effort and It is without question that his efforts helped shorten the war significantly, saving the lives of millions of people.He was also a remarkable British hero who helped create the modern world. Now known as the father of computer science, his inventions contributed greatly to the groundwork for the modern computer.

After the war he worked at the National Physical Laboratory, where he created one of the first designs for a stored-program computer, the ACE. In 1948 Turing joined Max Newman’s Computing Laboratory at Manchester University, where he assisted in the development of the Manchester computers and invented a type of theoretical machine now called a Turing Machine, which formalized what it means to compute a number. Turing’s importance extends far beyond Turing Machines. His work deciphering secret codes drastically shortened World War II and pioneered early computer technology.He was also an early innovator in the field of artificial intelligence, and came up with a way to test if computers could think – now known as the Turing Test. Besides this abstract work, he was down to earth; he designed and built real machines, even making his own relays and wiring up circuits. This combination of pure math and computing machines was the foundation of computer science.

Despite his achievements, and valuable contributions to cryptanalysis he was treated appallingly by the British Government and did not receive the recognition and plaudits that he deserved while alive because of his life style choices. A burglary at his home led Turing to admit to police that he was a practicing homosexual, at a time when it was illegal in Britain. This led to his arrest and conviction in 1952 for ‘gross indecency’. He was subsequently forced to choose between imprisonment and chemical castration. He chose chemical castration (treatment with female hormones) as an alternative to prison. As a result of his conviction he lost security clearance and was not allowed to continue his work. Sadly this all proved too much for Turing and On 8 June 1954 just over two weeks before his 42nd birthday, Turing was found dead from cyanide poisoning. An inquest determined that his death was suicide and he had poisoned himself with cyanide.

Thankfully since Turning’s birth most people’s attitudes have changed and most are now far more tolerant of people’s preferences. Since 1966 The US-based Association of Computing Machinery has annually awarded The Turing Award for technical contribution to the computing community. This is the computing world’s highest honour and is considered equivalent to the Nobel prize. On 10 September 2009, following an Internet campaign, British Prime Minister Gordon Brown also made an official public apology on behalf of the British government for “the appalling way he was treated”. There is also A fully functional rebuild of the Bombe which can be found today at Bletchley Park, along with the excellent Turing exhibition.

World Metrology Day

World Metrology Day takes place annually on the 20th of May. The date commemorates the anniversary of the signing of the Metre Convention in 1875 which standardised the International System of Units. Metrology is the science of measurement. It establishes a common understanding of units, crucial in linking human activities. Modern metrology has its roots in the French Revolution’s political motivation to standardise units in France, when a length standard taken from a natural source was proposed. This led to the creation of the decimal-based metric system in 1795, establishing a set of standards for other types of measurements. Several other countries adopted the metric system between 1795 and 1875; to ensure conformity between the countries, the Bureau International des Poids et Mesures (BIPM) was established by the Metre Convention. This has evolved into the International System of Units (SI) as a result of a resolution at the 11th Conference Generale des Poids et Mesures (CGPM) in 1960.

Metrology is divided into three basic kinds: the definition of units of measurement, the realisation of these units of measurement , and traceability, which is linking measurements made in practice to the reference standards. These overlapping activities are used in varying degrees by the three basic sub-fields of Metrology. The sub-fields are scientific or fundamental metrology, which is concerned with the establishment of units of measurement, Applied, technical or industrial metrology, the application of measurement to manufacturing and other processes in society, and Legal metrology, which covers the regulation and statutory requirements for measuring instruments and the methods of measurement.

In each country, a national measurement system (NMS) exists as a network of laboratories, calibration facilities and accreditation bodies which implement and maintain its metrology infrastructure. The NMS affects how measurements are made in a country and their recognition by the international community, which has a wide-ranging impact in its society (including economics, energy, environment, health, manufacturing, industry and consumer confidence. The effects of metrology on trade and economy are some of the easiest-observed societal impacts. To facilitate fair trade, there must be an agreed-upon system of measurement.

The history of measurement dates back to at least 2900 BC when The first record of a permanent standard, The royal Egyptian cubit was used. The cubit was decreed to be the length of the Pharaoh’s forearm plus the width of his hand, and replica standards were given to builders. The success of a standardised length for the building of the pyramids is indicated by the lengths of their bases differing by no more than 0.05 percent.

Other civilizations produced generally accepted measurement standards, with Roman and Greek architecture based on distinct systems of measurement. The collapse of the empires and the Dark Ages which followed them lost much measurement knowledge and standardisation. Although local systems of measurement were common, comparability was difficult since many local systems were incompatible. England established the Assize of Measures to create standards for length measurements in 1196, and the 1215 Magna Carta included a section for the measurement of wine and beer.

Modern metrology has its roots in the French Revolution. With a political motivation to harmonise units throughout France, a length standard based on a natural source was proposed. In March 1791, the metre was defined. This led to the creation of the decimal-based metric system in 1795, establishing standards for other types of measurements. Several other countries adopted the metric system between 1795 and 1875; to ensure international conformity, the International Bureau of Weights and Measures (French: Bureau International des Poids et Mesures, or BIPM) was established by the Metre Convention. Although the BIPM’s original mission was to create international standards for units of measurement and relate them to national standards to ensure conformity, its scope has broadened to include electrical and photometric units and ionizing radiation measurement standards. The metric system was modernised in 1960 with the creation of the International System of Units (SI) as a result of a resolution at the 11th General Conference on Weights and Measures (French: Conference Generale des Poids et Mesures, or CGP)

Metrology has wide-ranging impacts on a number of sectors, including economics, energy, the environment, health, manufacturing, industry, and consumer confidence.The effects of metrology on trade and the economy are two of its most-apparent societal impacts. To facilitate fair and accurate trade between countries, there must be an agreed-upon system of measurement. Accurate measurement and regulation of water, fuel, food, and electricity are critical for consumer protection and promote the flow of goods and services between trading partners. A common measurement system and quality standards benefit consumer and producer; production at a common standard reduces cost and consumer risk, ensuring that the product meets consumer needs. Transaction costs are reduced through an increased economy of scale. Several studies have indicated that increased standardisation in measurement has a positive impact on GDP. In the United Kingdom, an estimated 28.4 percent of GDP growth from 1921 to 2013 was the result of standardisation; in Canada between 1981 and 2004 an estimated nine percent of GDP growth was standardisation-related, and in Germany the annual economic benefit of standardisation is an estimated 0.72% of GDP.

Legal metrology has reduced accidental deaths and injuries with measuring devices, such as radar guns and breathalyzers, by improving their efficiency and reliability. Measuring the human body is challenging, with poor repeatability and reproducibility, and advances in metrology help develop new techniques to improve health care and reduce costs. Environmental policy is based on research data, and accurate measurements are important for assessing climate change and environmental regulation. Aside from regulation, metrology is essential in supporting innovation, the ability to measure provides a technical infrastructure and tools that can then be used to pursue further innovation. By providing a technical platform which new ideas can be built upon, easily demonstrated, and shared, measurement standards allow new ideas to be explored and expanded upon.

Jon Pertwee

Best known for  portraying the Third Doctor in the science-fiction series Doctor Who between 1970 and 1974, and starring as Worzel Gummidge, the English actor, entertainer and cabaret performer John Pertwee sadly died in his sleep from a heart attack in Connecticut on 20 May 1996, at the age of 76.

World Information Society Day

World Information Society Day (World Telecommunication Day) takes place on 17 May to commemorate the founding of the International Telecommunication Union in 17 May 1865  by the Plenipotentiary Conference in Malaga-Torremolinos.

The International Telecommunication Union (ITU; French: Union Internationale des Télécommunications (UIT)), originally the International Telegraph Union (French: Union Télégraphique Internationale), is a specialized agency of the United Nations (UN) that is responsible for issues that concern information and communication technologies. The ITU coordinates the shared global use of the radio spectrum, promotes international cooperation in assigning satellite orbits, works to improve telecommunication infrastructure in the developing world, and assists in the development and coordination of worldwide technical standards. The ITU is active in areas including broadband Internet, latest-generation wireless technologies, aeronautical and maritime navigation, radio astronomy, satellite-based meteorology, convergence in fixed-mobile phone, Internet access, data, voice, TV broadcasting, and next-generation networks. The agency also organizes worldwide and regional exhibitions and forums, such as ITU Telecom World, bringing together representatives of government and the telecommunications and ICT industry to exchange ideas, knowledge and technology.

The ITU, is based in Geneva, Switzerland, and is a member of the United Nations Development Group, and has 12 regional and area offices in the world. ITU has been an intergovernmental public–private partnership organization since its inception. Its membership includes 193 Member States and around 800 public and private sector companies, and academic institutions as well as international and regional telecommunication entities, known as Sector Members and Associates, which undertake most of the work of each Sector.

.It was introduced by a United Nations General Assembly resolution, after the World Summit on the Information Society (WSIS) in Tunis called upon the United Nations General Assembly to declare May 17th as World Information Society Day. The Main Objective of World Information Society Day is to focus on the importance of Computerised Information Technology, to raise global awareness of changes brought about by the Internet and new computerised Technologies, to raise awareness concerning other issues relating to the Information Society and to help reduce the digital divide. In March 2006 The General Assembly adopted a resolution (A/RES/60/252) stipulating that World Information Society Day shall be celebrated every year on 17 May. The first World Information Society Day took place on Wednesday, 17 May 2006.
