Nikola Tesla

Nikola Tesla day, is celebrated annually on July 10 to mark the birth of Serbian-American inventor, electrical engineer, mechanical engineer, physicist, and futurist Nikola Tesla who was born 10 July 1856 in Smiljan, Lika county, Serbia. Tesla received an advanced education in engineering and physics in the 1870s and gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. In 1881, Tesla moved to Budapest, Hungary, to work under Tivadar Puskás at a telegraph company, the Budapest Telephone Exchange. Upon arrival, Tesla realized that the company, then under construction, was not functional, so he worked as a draftsman in the Central Telegraph Office instead. Within a few months, the Budapest Telephone Exchange became functional, and Tesla was allocated the chief electrician and made many improvements to the Central Station equipment including the improvement of a telephone repeater or amplifier, which was never patented nor publicly described.

In 1882, Tivadar Puskás got Tesla another job in Paris with the Continental Edison Company.Tesla began working in what was then a brand new industry, installing indoor incandescent lighting citywide in the form of an electric power utility. The company had several subdivisions and Tesla worked at the Société Electrique Edison, the division in the Ivry-sur-Seine suburb of Paris in charge of installing the lighting system. There he gained a great deal of practical experience in electrical engineering. Management took notice of his advanced knowledge in engineering and physics and soon had him designing and building improved versions of generating dynamos and motors.They also sent him on to troubleshoot engineering problems at other Edison utilities being built around France and in Germany.

He emigrated to the United States in 1884, And got a job at the Edison Machine Works in New York City however he left in 1885 and began working on patenting an arc lighting system, In March 1885, he met with patent attorney Lemuel W. Serrell, the same attorney used by Edison, to obtain help with submitting the patents. Serrell introduced Tesla to two businessmen, Robert Lane and Benjamin Vail, who agreed to finance an arc lighting manufacturing and utility company in Tesla’s name, the Tesla Electric Light & Manufacturing. Tesla obtained patents for an improved DC generator, which was installed in Rahway, New Jersey. Tesla new system gained notice in the technical press, which commented on its advanced features. However the Investors decided against Tesla’s idea and formed a new utility company, abandoning Tesla’s company and leaving the inventor penniless Tesla even lost control of the patents he had generated.

In 1886, Tesla met Alfred S. Brown, a Western Union superintendent, and New York attorney Charles F. Peck andbased on Tesla’s new idea’s for electrical equipment, including a thermo-magnetic motor idea,they agreed to back the inventor financially and handle his patents. Together they formed the Tesla Electric Company in1887, And set up a laboratory for Tesla at 89 Liberty Street in Manhattan. In 1887, Tesla developed an induction motor that ran on alternating current, a power system format that was rapidly expanding in Europe and the United States because of its advantages in long-distance, high-voltage transmission. The motor used polyphase current, which generated a rotating magnetic field to turn the motor. This innovative electric motor, patented in May 1888, was a simple self-starting design that did not need a commutator, thus avoiding sparking and the need for constantly servicing and replacing mechanical brushes. Physicist William Arnold Anthony tested the motor and Electrical World magazine editor Thomas Commerford Martin arranged for Tesla to demonstrate his alternating current motor on 16 May 1888 at the American Institute of Electrical Engineers. George Westinghouse was also working on a device similar device To Tesla’s polyphase induction motor and transformer and Westinghouse also hired Tesla for one year to be a consultant at the Westinghouse Electric & Manufacturing Company’s Pittsburgh labs. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company would eventually market.

In 1889, Tesla traveled to the 1889 Exposition Universelle in Paris and learned of Heinrich Hertz’ 1886–88 experiments that proved the existence of electromagnetic radiation, including radio waves. Tesla decided to explore it by repeating and then expanding on these experiments, Tesla tried powering a Ruhmkorff coil with a high speed alternator he had been developing as part of an improved arc lighting system but found that the high frequency current overheated the iron core and melted the insulation between the primary and secondary windings in the coil. To fix this problem Tesla came up with his Tesla coil with an air gap instead of insulating material between the primary and secondary windings and an iron core that could be moved to different positions in or out of the coil.

After 1890, Tesla experimented with transmitting power by inductive and capacitive coupling using high AC voltages generated with his Tesla coil. He attempted to develop a wireless lighting system based on near-field inductive and capacitive coupling and conducted a series of public demonstrations where he lit Geissler tubes and even incandescent light bulbs from across a stage. In 1893 at St. Louis, Missouri, the Franklin Institute in Philadelphia, Pennsylvania and the National Electric Light Association, Tesla told onlookers that he was sure a system like his could eventually conduct “intelligible signals or perhaps even power to any distance without the use of wires” by conducting it through the Earth. Tesla served as a vice-president of the American Institute of Electrical Engineers from 1892 to 1894, the forerunner of the modern-day IEEE (along with the Institute of Radio Engineers).

Tesla also conducted a range of experiments with mechanical oscillators/generators, electrical discharge tubes, and early X-ray imaging. He also built a wireless-controlled boat, one of the first ever exhibited. Tesla became well known as an inventor And Throughout the 1890s, Tesla experimented with wireless lighting and worldwide wireless electric power distribution in his high-voltage, high-frequency power experiments in New York and Colorado Springs. In 1893, he Worked on a device enabling wireless communication and tried to put these ideas to practical use in his unfinished Wardenclyffe Tower project, an intercontinental wireless communication and power transmitter.

After Wardenclyffe, Tesla went on to try and develop a series of inventions in the 1910s and 1920s with varying degrees of success. He is best known for his contributions to the design of the modern alternating current (AC) electricity supply system. Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison. He soon struck out on his own with financial backers, setting up laboratories/companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla as a consultant to help develop apower system using alternating current. Tesla is also known for his high-voltage, high-frequency power experiments in New York and Colorado Springs which included patented devices and theoretical work used in the invention of radiocommunication, for his X-ray experiments, and for his ill-fated attempt at intercontinental wireless transmission in his unfinished Wardenclyffe Towerproject.

Tesla’s achievements and his abilities as a showman demonstrating his seemingly miraculous inventions made him world-famous.Although he made a great deal of money from his patents, he spent a lot on numerous experiments. He lived for most of his life in a series of New York hotels although the end of his patent income and eventual bankruptcy led him to live in diminished circumstances. Despite this Tesla still continued to invite the press to parties he held on his birthday to announce new inventions he was working and make (sometimes unusual) statements. Because of his pronouncements and the nature of his work over the years, Tesla gained a reputation in popular culture as the archetypal “mad scientist”.

Sadly Tesla passed away on 7 January 1943 in room 3327 of the New Yorker Hotel and his work fell into relative obscurity after his death, but since the 1990s, his reputation has experienced a comeback in popular culture. His work and reputed inventions are also at the center of many conspiracy theories and have also been used to support various pseudosciences, UFO theories and New Age occultism. In 1960, in honor of Tesla, the General Conference on Weights and Measures for the International System of Units dedicated the term “tesla” to the SI unit measure for magnetic field strength. There is also an Electric Car named after him.

International Asteroid Day

The United Nations has declared “30 June as International Asteroid Day to mark the anniversary of the Siberian Tunguska event that took place on June 30th, 1908, and is the most harmful known asteroid-related event on Earth in recent history and to raise public awareness about the asteroid impact hazard
Asteroid Day also aims to raise awareness about asteroids and what can be done to protect the Earth, its families, communities, and future generations from a catastrophic event.

Asteroid Day was co-founded by filmmaker Grigorij Richters, B612 Foundation COO Danica Remy, Apollo 9 astronaut Rusty Schweickart and Brian May, Queen guitarist and astrophysicist. Over 200 astronauts, scientists, technologists and artists, including Richard Dawkins, Bill Nye, Peter Gabriel, Jim Lovell, Apollo 11 Astronaut Michael Collins, Alexei Leonov, Bill Anders, Kip Thorne, Lord Martin Rees, Chris Hadfield, Rusty Schweickart and Brian Cox co-signed the Asteroid Day Declaration. Asteroid Day was officially launched on December 3, 2014. In February 2014, Brian May, astrophysicist and guitarist for the rock band Queen, began working with Grigorij Richters, director of the film 51 Degrees North, the story of a fictional asteroid impact on London and the human condition resulting from such an event. May composed the music for the film. After screening the film at the 2014 Starmus Festival, Richters and May co-founded Asteroid Day in October 2014 which they officially announced during a press conference with Lord Martin Rees, Rusty Schweickart, Ed Lu, Thomas Jones, Ryan Watt and Bill Nye. The event was live streamed from the Science Museum in London, the California Academy of Sciences, New York and São Paulo. On Asteroid Day 2017, minor planet 248750 (discoverer M.Dawson) was officially named Asteroidday by the International Astronomical Union.

The workgroup of Asteroid Day created a declaration called “100X Declaration”, which appeals to all scientists and technologists who are supporting the idea of saving the earth from asteroids, but not only specialists are asked to sign, everyone can sign this declaration. Today, the 100X Declaration has been signed by more than 22,000 private citizens. More than 1M asteroids have the potential to impact Earth and through all the available telescopes worldwide, we have discovered only about one percent. The 100X Declaration calls for increasing the asteroid discovery rate to 100,000 (or 100x) per year within the next 10 years. The more we learn about asteroid impacts, the clearer it became that the human race has been living on borrowed time.

Asteroid Day and the 100X Declaration are ways for the public to contribute to an awareness of the Earth’s vulnerability and the realization that Asteroids hit Earth all the time. Asteroid Day is also a way garner public support to increase our knowledge of when asteroids might strike and how we can protect ourselves.” The main three goals are:

  • Employ available technology to detect and track Near-Earth Asteroids that threaten human populations via governments and private and philanthropic organisations.
  • To acceleratethe discovery and tracking of Near-Earth Asteroids to 100,000 per year within the next ten years.
  • to adopt Asteroid Day Globally to increase awareness of the asteroid hazard and our efforts to prevent impacts.

On Asteroid Day 2015-2016, there were over 600 events According to the AsteroidDay.org website in 78 countries participated. The general goal was to raise awareness about the threat posed by asteroid impacts. Institutions such as the Natural History Museum in Vienna, the American Natural History Museum, the California Academy of Sciences, the Science Museum in London, the SETI institute, the European Space Agency, the UK Space Agency, and others participated in educational activities. The first Asteroid Day was held on June 30, 2015. In February 2016, Romanian astronaut Dumitru Prunariu and the Association of Space Explorers submitted a proposal to the Scientific and Technical Subcommittee of the United Nations which was accepted by the subcommittee and in June 2016 the United Nations Committee on the Peaceful Uses of Outer Space included the recommendation in its report. The report of the Committee was presented for approval to the United Nations General Assembly’s 71st session which it approved on December 6, 2016..”

World Sickle Cell day

World Sickle Cell Day occours yearly on 19th June to raise awareness of InteSickle-cell disease (SCD), or sickle-cell anaemia (SCA) or drepanocytosis. Sickle Cell disease is a hereditary group of blood disorders typically inherited from a person’s parents. It is characterized by red blood cells that assume an abnormal, rigid, sickleshape. This so called “Sickling” of the red blood cells decreases the cells’ flexibility and results in a risk of various complications. The sickling occurs because of a mutation in the haemoglobin gene. Individuals with one copy of the defunct gene display both normal and abnormal haemoglobin. This is an example of codominance. In 1994, in the US, the average life expectancy of persons with this condition was estimated to be 42 years in males and 48 years in females. The average life expectancy in the developed world is 40 to 60 years However, thanks to better management of the disease, some patients can now live into their 70s or beyond.

The condition was first described in the medical literature by the American physician James B. Herrick in 1910. In 1949, the genetic transmission was determined by E. A. Beet and J. V. Neel. In 1954, the protective effect against malaria of sickle cell trait was described. Sickle-cell disease occurs more commonly among people whose ancestors lived in tropical and sub-tropical sub-saharan regions where malaria is or was common. Where malaria is common, carrying a single sickle-cell gene (sickle cell trait) confers a fitness. Specifically, humans with one of the two alleles of sickle-cell disease show less severe symptoms when infected with malaria.

Sickle-cell anaemia is a form of sickle-cell disease in which there is homozygosity for themutation that causes HbS. Sickle-cell anaemia is also referred to as “HbSS”, “SS disease”, “haemoglobin S” or permutations of those names. It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. This leads to a rigid, sickle-like shape under certain circumstances.
In heterozygous people, that is, those who have only one sickle gene and one normal adult haemoglobin gene, the condition is referred to as “HbAS” or “sickle cell trait”. Other, rarer forms of sickle-cell disease arecompound heterozygous states in which the person has only one copy of the mutation that causes HbS and one copy of another abnormal haemoglobin allele. They include sickle-haemoglobin C disease (HbSC), sickle beta-plus-thalassaemia (HbS/β+) and sickle beta-zero-thalassaemia (HbS/β0). The term disease is applied because the inherited abnormality causes a pathological condition that can lead to death and severe complications. However Not all inherited variants of haemoglobin are detrimental, a concept known as genetic polymorphism.

Sickle cell disease occurs when a person inherits two abnormal copies of the haemoglobin gene, one from each parent. This gene occurs in chromosome 11. Several subtypes exist, depending on the exact mutation in each haemoglobin gene. An attack can be set off by temperature changes, stress, dehydration and high altitude. A person with a single abnormal copy does not usually have symptoms and is said to have sickle cell trait. Such people are also referred to as carriers. Diagnosis is by a blood test, and some countries test all babies at birth for the disease. Diagnosis is also possible during pregnancy.

Problems in sickle cell disease typically begin around 5 to 6 months of age. A number of health problems may develop, such as attacks of pain (“sickle cell crisis”), anemia, swelling in the hands and feet, bacterial infections and stroke. Long-term pain may develop as people get older. The care of people with sickle cell disease may include infection prevention with vaccination and antibiotics, high fluid intake, folic acid supplementation and pain medication. Other measures may include blood transfusion and the medication hydroxycarbamide (hydroxyurea). A small percentage of people can be cured by a transplant of bone marrow cells. .

As of 2015, about 4.4 million people have sickle cell disease, while an additional 43 million have sickle cell trait.About 80% of sickle cell disease cases are believed to occur in Sub-Saharan Africa. It also occurs relatively frequently in parts of India, the Arabian Peninsula and among people of African origin living in other parts of the world. In 2015, it resulted in about 114,800 deaths.

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

Tim Berners Lee OM KBE FRS FREng FRSA FBCS

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 later. 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. It then was accepted by his manager, Mike Sendall.[29] 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.[29] Although the two terms are sometimes conflated in popular use, World Wide Web is not synonymous with Internet.[30]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.

Robert Moog

Best known as the inventor of the Moog synthesizer, The pioneer of electronic music, Robert Moog (Pronounced “Mogue”) was born on 23rd May 1934. Bob Moog’s innovative electronic design is employed in numerous synthesizers including the Minimoog Model D, Minimoog Voyager, Little Phatty, Moog Taurus Bass Pedals, Moog Minitaur, and the Moogerfooger line of effects pedals.He was born in New York and attended the Bronx High School of Science in New York, graduating in 1952. Moog earned a bachelor’s degree in physics from Queens College, New York in 1957, another in electrical engineering from Columbia University, and a Ph.D. in engineering physics from Cornell University. Moog’s awards include honorary doctorates from Polytechnic Institute of New York University (New York City) and Lycoming College (Williamsport, Pennsylvania).Moog created the first voltage-controlled subtractive synthesizer to utilize a keyboard as a controller and demonstrated it at the AES convention in 1964. In 1966, Moog filed a patent application for his unique low-pass filter which issued in October 1969. He held several dozen patents.

 

Moog also employed his theremin company (R. A. Moog Co., which would later become Moog Music) to manufacture and market his synthesizers. Unlike the few other 1960s synthesizer manufacturers, Moog shipped a piano-style keyboard as the standard user interface to his synthesizers. Moog also established standards for analog synthesizer control interfacing, with a logarithmic one volt-per-octave pitch control and a separate pulse triggering signal. The first instrument – The Moog modular synthesizer became one of the first widely used electronic musical instruments. Early developmental work on the components of the synthesizer occurred at the Columbia-Princeton Electronic Music Center, now the Computer Music Center. While there, Moog developed the voltage controlled oscillators, ADSR envelope generators, and other synthesizer modules with composer Herbert Deutsch. In 1971 Moog Music began production of the Minimoog Model D which was among the first widely available, portable and relatively affordable synthesizers. One of Moog’s earliest musical customers was Wendy Carlos whom he credits with providing feedback that was valuable to the further development of Moog synthesizers.Moog also constructed his own theremin as early as 1948. Later he described a theremin in the hobbyist magazine Electronics World and offered a kit of parts for the construction of the Electronic World’s Theremin, which became very successful.

In the late 1980s Moog repaired the original theremin of Clara Rockmore, an accomplishment which he considered a high point of his professional career. He also produced, in collaboration with first wife Shirleigh Moog, Mrs. Rockmore’s album, The Art of the Theremin. Moog was a principal interview subject in the award-winning documentary film, Theremin: An Electronic Odyssey, the success of which led to a revival of interest in the theremin. Moog Music went back to its roots and once again began manufacturing theremins. Thousands have been sold to date and are used by both professional and amateur musicians around the globe. In 1996 he published another do-it-yourself theremin guide. Today, Moog Music is the leading manufacturer of performance-quality thereminsThrough his involvement in electronic music, Moog developed close professional relationships with artists such as Don Buchla, Keith Emerson, Rick Wakeman, John Cage, Gershon Kingsley, Clara Rockmore, Jean Jacques Perrey , and Pamelia Kurstin.

In a 2000 interview, Moog said “I’m an engineer. I see myself as a toolmaker and the musicians are my customers. They use my tools.”During his lifetime, Moog founded two companies for manufacturing electronic musical instruments -RA Moog Co who manufactured Theramin Kits but left after a disagreement and formed a company called Big Briar. He also worked as a consultant and vice president for new product research at Kurzweil Music Systems from 1984 to 1988, helping to develop the Kurzweil K2000. He spent the early 1990s as a research professor of music at the University of North Carolina at Asheville. During his lifetime Moog received a Grammy Trustees Award for lifetime achievement in 1970, and In 2002, Moog was honored with a Special Merit/Technical Grammy Award, and an honorary doctorate degree from Berklee College of Music. Moog was also the inspiration behind the 2004 film Moog.

Sadly he was diagnosed with a glioblastoma multiforme brain tumor on April 28, 2005 and passed away nearly four months later, at the age of 71 in Asheville, North Carolina on August 21, 2005. The Bob Moog Foundation was created as a memorial, with the aim of continuing his life’s work of developing electronic music. He is survived by three daughters (Laura Moog Lanier, Michelle Moog-Koussa, Renee Moog) one son (Matthew Moog) one stepdaughter, Miranda Richmond, and five grandchildren.
