Canadians
–
Canadians are people identified with the country of Canada. This connection may be residential, legal, historical, or cultural, for most Canadians, several of these connections exist and are collectively the source of their being Canadian. Elements of Aboriginal, French, British and more recent immigrant customs, languages and religions have combined to form the culture of Canada, Canada has also been strongly influenced by its linguistic, geographic and economic neighbour, the United States. Canadian independence from the United Kingdom grew gradually over the course of years since the formation of the Canadian Confederation in 1867. World War I and World War II in particular gave rise to a desire among Canadians to have their country recognized as a sovereign state with a distinct citizenship. Canadas nationality law closely mirrored that of the United Kingdom, legislation since the mid 20th century represents Canadians commitment to multilateralism and socioeconomic development. As of 2010, Canadians make up 0. 5% of the total population, having relied upon immigration for population growth. Approximately 41% of current Canadians are first- or second-generation immigrants, and 20 percent of Canadian residents in the 2000s were not born in the country. Statistics Canada projects that, by 2031, nearly one-half of Canadians above the age of 15 will be foreign-born or have one foreign-born parent. Aboriginal peoples, according to the 2011 Canadian Census, numbered at 1,400,685 or 4. 3% of the countrys 33,476,688 population. The French originally settled New France, in present-day Quebec and Ontario, approximately 100 Irish-born families would settle the Saint Lawrence Valley by 1700, assimilating into the Canadien population and culture. This arrival of newcomers led to the creation of the Métis, after the War of 1812, British, Scottish and Irish immigration was encouraged throughout Ruperts Land, Upper Canada and Lower Canada. Between 1815 and 1850, some 800,000 immigrants came to the colonies of British North America and these new arrivals included some Gaelic-speaking Highland Scots displaced by the Highland Clearances to Nova Scotia. Descendants of Francophone and Anglophone northern Europeans who arrived in the 17th, 18th and 19th centuries are often referred to as old stock Canadians. Beginning in the late 1850s, the immigration of Chinese into the Colony of Vancouver Island, the Chinese Immigration Act of 1885 eventually placed a head tax on all Chinese immigrants, in hopes of discouraging Chinese immigration after completion of the Canadian Pacific Railway. The population of Canada has consistently risen, doubling approximately every 40 years, from the mid- to late 19th century, Canada had a policy of assisting immigrants from Europe, including an estimated 100,000 unwanted Home Children from Britain. Block settlement communities were established throughout western Canada between the late 19th and early 20th centuries, some were planned and others were spontaneously created by the settlers themselves. Canada was now receiving a number of European immigrants, predominantly Italians, Germans, Scandinavians, Dutch, Poles

Physicist
–
A physicist is a scientist who has specialized knowledge in the field of physics, the exploration of the interactions of matter and energy across the physical universe. A physicist is a scientist who specializes or works in the field of physics, physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists can also apply their knowledge towards solving real-world problems or developing new technologies, some physicists specialize in sectors outside the science of physics itself, such as engineering. The study and practice of physics is based on a ladder of discoveries. Many mathematical and physical ideas used today found their earliest expression in ancient Greek culture and Asian culture, the bulk of physics education can be said to flow from the scientific revolution in Europe, starting with the work of Galileo and Kepler in the early 1600s. New knowledge in the early 21st century includes an increase in understanding physical cosmology. The term physicist was coined by William Whewell in his 1840 book The Philosophy of the Inductive Sciences, many physicist positions require an undergraduate degree in applied physics or a related science or a Masters degree like MSc, MPhil, MPhys or MSci. In a research oriented level, students tend to specialize in a particular field, Physics students also need training in mathematics, and also in computer science and programming. For being employed as a physicist a doctoral background may be required for certain positions, undergraduate students like BSc Mechanical Engineering, BSc Electrical and Computer Engineering, BSc Applied Physics. etc. With physics orientation are chosen as research assistants with faculty members, the highest honor awarded to physicists is the Nobel Prize in Physics, awarded since 1901 by the Royal Swedish Academy of Sciences. The three major employers of career physicists are academic institutions, laboratories, and private industries, with the largest employer being the last, physicists in academia or government labs tend to have titles such as Assistants, Professors, Sr. /Jr. As per the American Institute for Physics, some 20% of new physics Ph. D. s holds jobs in engineering development programs, while 14% turn to computer software, a majority of physicists employed apply their skills and training to interdisciplinary sectors. For industry or self-employment. and also in science and programming. Hence a majority of Physics bachelors degree holders are employed in the private sector, other fields are academia, government and military service, nonprofit entities, labs and teaching
3.
Composer
–
A composer is a person who creates or writes music, which can be vocal music, instrumental music or music which combines both instruments and voices. The core meaning of the term refers to individuals who have contributed to the tradition of Western classical music through creation of works expressed in written musical notation, many composers are also skilled performers, either as singers, instrumentalists, and/or conductors. Examples of composers who are well known for their ability as performers include J. S. Bach, Mozart. In many popular genres, such as rock and country. For a singer or instrumental performer, the process of deciding how to perform music that has previously composed and notated is termed interpretation. Different performers interpretations of the work of music can vary widely, in terms of the tempos that are chosen. Composers and songwriters who present their own music are interpreting, just as much as those who perform the music of others, although a musical composition often has a single author, this is not always the case. A piece of music can also be composed with words, images, or, in the 20th and 21st century, a culture eventually developed whereby faithfulness to the composers written intention came to be highly valued. This musical culture is almost certainly related to the esteem in which the leading classical composers are often held by performers. The movement might be considered a way of creating greater faithfulness to the original in works composed at a time that expected performers to improvise. In Classical music, the composer typically orchestrates her own compositions, in some cases, a pop songwriter may not use notation at all, and instead compose the song in her mind and then play or record it from memory. In jazz and popular music, notable recordings by influential performers are given the weight that written scores play in classical music. The level of distinction between composers and other musicians varies, which issues such as copyright and the deference given to individual interpretations of a particular piece of music. In the development of European classical music, the function of composing music initially did not have greater importance than that of performing it. The preservation of individual compositions did not receive attention and musicians generally had no qualms about modifying compositions for performance. In as much as the role of the composer in western art music has seen continued solidification, for instance, in certain contexts the line between composer and performer, sound designer, arranger, producer, and other roles, can be quite blurred. The term composer is often used to refer to composers of music, such as those found in classical, jazz or other forms of art. In popular and folk music, the composer is usually called a songwriter and this is distinct from a 19th-century conception of instrumental composition, where the work was represented solely by a musical score to be interpreted by performers

Ontario
–
Ontario, one of the 13 provinces and territories of Canada, is located in east-central Canada. It is Canadas most populous province by a margin, accounting for nearly 40 percent of all Canadians. Ontario is fourth-largest in total area when the territories of the Northwest Territories and it is home to the nations capital city, Ottawa, and the nations most populous city, Toronto. There is only about 1 km of land made up of portages including Height of Land Portage on the Minnesota border. Ontario is sometimes divided into two regions, Northern Ontario and Southern Ontario. The great majority of Ontarios population and arable land is located in the south, in contrast, the larger, northern part of Ontario is sparsely populated with cold winters and is heavily forested. The province is named after Lake Ontario, a thought to be derived from Ontarí, io, a Huron word meaning great lake, or possibly skanadario. Ontario has about 250,000 freshwater lakes, the province consists of three main geographical regions, The thinly populated Canadian Shield in the northwestern and central portions, which comprises over half the land area of Ontario. Although this area mostly does not support agriculture, it is rich in minerals and in part covered by the Central and Midwestern Canadian Shield forests, studded with lakes, Northern Ontario is subdivided into two sub-regions, Northwestern Ontario and Northeastern Ontario. The virtually unpopulated Hudson Bay Lowlands in the north and northeast, mainly swampy. Southern Ontario which is further sub-divided into four regions, Central Ontario, Eastern Ontario, Golden Horseshoe, the highest point is Ishpatina Ridge at 693 metres above sea level located in Temagami, Northeastern Ontario. In the south, elevations of over 500 m are surpassed near Collingwood, above the Blue Mountains in the Dundalk Highlands, the Carolinian forest zone covers most of the southwestern region of the province. A well-known geographic feature is Niagara Falls, part of the Niagara Escarpment, the Saint Lawrence Seaway allows navigation to and from the Atlantic Ocean as far inland as Thunder Bay in Northwestern Ontario. Northern Ontario occupies roughly 87 percent of the area of the province. Point Pelee is a peninsula of Lake Erie in southwestern Ontario that is the southernmost extent of Canadas mainland, Pelee Island and Middle Island in Lake Erie extend slightly farther. All are south of 42°N – slightly farther south than the border of California. The climate of Ontario varies by season and location, the effects of these major air masses on temperature and precipitation depend mainly on latitude, proximity to major bodies of water and to a small extent, terrain relief. In general, most of Ontarios climate is classified as humid continental, Ontario has three main climatic regions

Queen's University
–
Queens University at Kingston is a public research university in Kingston, Ontario, Canada. Founded on 16 October 1841 via a charter issued by Queen Victoria. Queens holds more than 1,400 hectares of land throughout Ontario and owns Herstmonceux Castle in East Sussex, Queens is organized into ten undergraduate, graduate and professional faculties and schools. The Church of Scotland established Queens College in 1841 with a charter from Queen Victoria. The first classes, intended to prepare students for the ministry, were held 7 March 1842 with 13 students, Queens was the first university west of the maritime provinces to admit women and to form a student government. In 1883, a college for medical education affiliated with Queens University was established. In 1888, Queens University began offering courses, becoming the first Canadian university to do so. In 1912, Queens secularized and changed to its present legal name, Queens is a co-educational university, with more than 23,000 students, and with over 131,000 living alumni worldwide. Notable alumni include government officials, academics, business leaders and 57 Rhodes Scholars, Queens varsity teams, known as the Golden Gaels, compete in the Ontario University Athletics conference of U Sports. Queens was a result of an outgrowth of educational initiatives planned by Presbyterians in the 1830s, a draft plan for the university was presented at a synod meeting in Kingston in 1839, with a modified bill introduced through the 13th Parliament of Upper Canada during a session in 1840. On 16 October 1841, a charter was issued through Queen Victoria establishing Queens College at Kingston. They modelled the university after the University of Edinburgh and the University of Glasgow, classes began on 7 March 1842, in a small wood-frame house on the edge of the city with two professors and 15 students. The college moved several times during its first eleven years, before settling in its present location, prior to Canadian Confederation, the college was financially supported by the Presbyterian Church in Scotland, the Canadian government and private citizens. The college was rescued after Principal William Snodgrass and other created a fundraising campaign across Canada. The risk of financial ruin continued to worry the administration until the final decade. They actively considered leaving Kingston and merging with the University of Toronto as late as the 1880s, with the additional funds bequeathed from Queens first major benefactor, Robert Sutherland, the college staved off financial failure and maintained its independence. Queens was given university status on 17 May 1881, in 1883, Womens Medical College was founded at Queens with a class of three. Theological Hall, completed in 1880, originally served as Queens main building throughout the late 19th century, in 1912, Queens separated from the Presbyterian Church of Scotland and changed its name to Queens University at Kingston

National Research Council (Canada)
–
The National Research Council is the primary national research and technology organization of the Government of Canada, in science and technology research and development. The Minister of Innovation, Science, and Economic Development is responsible for the National Research Council, the transformation of the NRC into an RTO that focuses on business-led research was part of the federal governments Economic Action Plan. With these services, NRC intends to shorten the gap between early research and development and commercialization. NRC now has over 30 approved programs, NRC is a Government of Canada organization. It’s mandate is set out in the National Research Council Act, in 2011, NRC President John R. McDougall, began to oversee a change in research focus away from basic research and towards industrial-relevant research. This included the development of programs, shifting research budget out of existing research. The NRC was not involved in this area of prior to the arrival of Mr. McDougall. The Canadian Wheat Improvement Program is a collaboration with Agriculture and Agri-Food Canada, the University of Saskatchewan’s Crop Development Centre. Working with breeders and scientists at the Crop Development Centre and at AAFC, the GaN Electronics program supports partner research and development activities with a goal of ensuring that GaN technology will create wealth and a greener future for Canadians. NRC is the only Canadian foundry for GaN electronics, and offers both normally-on and normally-off devices, the GaN500v2 Foundry Design Kit was released on June 28,2014. The NRC is managed by a governing council, current members of the council are, Patricia Béretta, PhD. Wayne Gulliver, dermatologist, President Newlab Clinical Research Inc. James P, louise Proulx, PhD, Vice-President, Product Development, Topigen Pharmaceuticals Inc. Close to 4,000 people across Canada are employed by the NRC, in addition, the Council also employs guest workers from universities, companies, and public and private-sector organizations. The NRC was established in 1916 under the pressure of World War I to advise the government on matters of science, in 1932, laboratories were built on Sussex Drive in Ottawa. With the impetus of World War II, the NRC grew rapidly and for all practical purposes became a military science, a special branch known as the Examination Unit was involved with cryptology and the interception of enemy radio communications. According to the Canadian Security Intelligence Service website, the NRC headquarters in Ottawa was a prime target during the Cold War. The NRC was also engaged in atomic fission research at the Montreal Laboratory, post-WWII, the NRC reverted to its pre-war civilian role and a number of wartime activities were spun off to newly formed organizations. Atomic research went to the newly created Atomic Energy of Canada Limited, foreign signals intelligence gathering officially remained with the agency when, by Order in Council, the Examination Unit became the Communications Branch of the NRC in 1946

Atomic physics
–
Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. It is primarily concerned with the arrangement of electrons around the nucleus and this comprises ions, neutral atoms and, unless otherwise stated, it can be assumed that the term atom includes ions. The term atomic physics can be associated with power and nuclear weapons, due to the synonymous use of atomic. Physicists distinguish between atomic physics — which deals with the atom as a system consisting of a nucleus and electrons — and nuclear physics, which considers atomic nuclei alone. As with many fields, strict delineation can be highly contrived and atomic physics is often considered in the wider context of atomic, molecular. Physics research groups are usually so classified, Atomic physics primarily considers atoms in isolation. Atomic models will consist of a nucleus that may be surrounded by one or more bound electrons. It is not concerned with the formation of molecules, nor does it examine atoms in a state as condensed matter. It is concerned with such as ionization and excitation by photons or collisions with atomic particles. This means that the atoms can be treated as if each were in isolation. By this consideration atomic physics provides the underlying theory in physics and atmospheric physics. Electrons form notional shells around the nucleus and these are normally in a ground state but can be excited by the absorption of energy from light, magnetic fields, or interaction with a colliding particle. Electrons that populate a shell are said to be in a bound state, the energy necessary to remove an electron from its shell is called the binding energy. Any quantity of energy absorbed by the electron in excess of this amount is converted to kinetic energy according to the conservation of energy, the atom is said to have undergone the process of ionization. If the electron absorbs a quantity of less than the binding energy. After a certain time, the electron in a state will jump to a lower state. In a neutral atom, the system will emit a photon of the difference in energy, if an inner electron has absorbed more than the binding energy, then a more outer electron may undergo a transition to fill the inner orbital. The Auger effect allows one to multiply ionize an atom with a single photon, there are rather strict selection rules as to the electronic configurations that can be reached by excitation by light — however there are no such rules for excitation by collision processes

Ottawa
–
Ottawa is the capital city of Canada. It stands on the bank of the Ottawa River in the eastern portion of southern Ontario. Ottawa borders Gatineau, Quebec, the two form the core of the Ottawa–Gatineau census metropolitan area and the National Capital Region. The 2016 census reported a population of 934,243, making it the fourth-largest city in Canada, the City of Ottawa reported that the city had an estimated population of 960,754 as of December 2015. Founded in 1826 as Bytown, and incorporated as Ottawa in 1855, the city name Ottawa was chosen in reference to the Ottawa River nearby, the name of which is derived from the Algonquin Odawa, meaning to trade. The city is the most educated in Canada, and is home to a number of post-secondary, research, and cultural institutions, including the National Arts Centre, Ottawa also has the highest standard of living in the nation and low unemployment. It ranked second out of 150 worldwide in the Numbeo quality of life index 2014–2015, with the draining of the Champlain Sea around ten thousand years ago the Ottawa Valley became habitable. The area was used for wild harvesting, hunting, fishing, trade, travel. The Ottawa river valley has archaeological sites with arrow heads, pottery, the area has three major rivers that meet, making it an important trade and travel area for thousands of years. The Algonquins called the Ottawa River Kichi Sibi or Kichissippi meaning Great River or Grand River, Étienne Brûlé, the first European to travel up the Ottawa River, passed by Ottawa in 1610 on his way to the Great Lakes. Three years later, Samuel de Champlain wrote about the waterfalls of the area and about his encounters with the Algonquins, the early explorers and traders were later followed by many missionaries. The first maps of the area used the word Ottawa to name the river, philemon Wright, a New Englander, created the first settlement in the area on 7 March 1800 on the north side of the river, across from Ottawa in Hull. He, with five other families and twenty-five labourers, set about to create a community called Wrightsville. Wright pioneered the Ottawa Valley timber trade by transporting timber by river from the Ottawa Valley to Quebec City, the following year, the town would soon be named after British military engineer Colonel John By who was responsible for the entire Rideau Waterway construction project. Colonel By set up military barracks on the site of todays Parliament Hill and he also laid out the streets of the town and created two distinct neighbourhoods named Upper Town west of the canal and Lower Town east of the canal. Similar to its Upper Canada and Lower Canada namesakes, historically Upper Town was predominantly English speaking and Protestant whereas Lower Town was predominantly French, Irish, bytowns population grew to 1,000 as the Rideau Canal was being completed in 1832. In 1855 Bytown was renamed Ottawa and incorporated as a city, William Pittman Lett was installed as the first city clerk guiding it through 36 years of development. On New Years Eve 1857, Queen Victoria, as a symbolic, in reality, Prime Minister John A. Macdonald had assigned this selection process to the Executive Branch of the Government, as previous attempts to arrive at a consensus had ended in deadlock

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Radar
–
Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, Radio waves from the transmitter reflect off the object and return to the receiver, giving information about the objects location and speed. Radar was developed secretly for military use by several nations in the period before, the term RADAR was coined in 1940 by the United States Navy as an acronym for RAdio Detection And Ranging or RAdio Direction And Ranging. The term radar has since entered English and other languages as a common noun, high tech radar systems are associated with digital signal processing, machine learning and are capable of extracting useful information from very high noise levels. Other systems similar to make use of other parts of the electromagnetic spectrum. One example is lidar, which uses ultraviolet, visible, or near infrared light from lasers rather than radio waves, as early as 1886, German physicist Heinrich Hertz showed that radio waves could be reflected from solid objects. In 1895, Alexander Popov, an instructor at the Imperial Russian Navy school in Kronstadt. The next year, he added a spark-gap transmitter, in 1897, while testing this equipment for communicating between two ships in the Baltic Sea, he took note of an interference beat caused by the passage of a third vessel. In his report, Popov wrote that this phenomenon might be used for detecting objects, the German inventor Christian Hülsmeyer was the first to use radio waves to detect the presence of distant metallic objects. In 1904, he demonstrated the feasibility of detecting a ship in dense fog and he obtained a patent for his detection device in April 1904 and later a patent for a related amendment for estimating the distance to the ship. He also got a British patent on September 23,1904 for a radar system. It operated on a 50 cm wavelength and the radar signal was created via a spark-gap. In 1915, Robert Watson-Watt used radio technology to advance warning to airmen. Watson-Watt became an expert on the use of direction finding as part of his lightning experiments. As part of ongoing experiments, he asked the new boy, Arnold Frederic Wilkins, Wilkins made an extensive study of available units before selecting a receiver model from the General Post Office. Its instruction manual noted that there was fading when aircraft flew by, in 1922, A. Hoyt Taylor and Leo C. Taylor submitted a report, suggesting that this might be used to detect the presence of ships in low visibility, eight years later, Lawrence A. Australia, Canada, New Zealand, and South Africa followed prewar Great Britain, and Hungary had similar developments during the war. Hugon, began developing a radio apparatus, a part of which was installed on the liner Normandie in 1935

Nuclear physics
–
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions. Other forms of matter are also studied. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, discoveries in nuclear physics have led to applications in many fields. Such applications are studied in the field of nuclear engineering, Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of physics to astrophysics, is crucial in explaining the inner workings of stars. The discovery of the electron by J. J. Thomson a year later was an indication that the atom had internal structure, in the years that followed, radioactivity was extensively investigated, notably by Marie and Pierre Curie as well as by Ernest Rutherford and his collaborators. By the turn of the physicists had also discovered three types of radiation emanating from atoms, which they named alpha, beta, and gamma radiation. Experiments by Otto Hahn in 1911 and by James Chadwick in 1914 discovered that the beta decay spectrum was continuous rather than discrete. That is, electrons were ejected from the atom with a range of energies, rather than the discrete amounts of energy that were observed in gamma. This was a problem for physics at the time, because it seemed to indicate that energy was not conserved in these decays. The 1903 Nobel Prize in Physics was awarded jointly to Becquerel for his discovery and to Marie, Rutherford was awarded the Nobel Prize in Chemistry in 1908 for his investigations into the disintegration of the elements and the chemistry of radioactive substances. In 1905 Albert Einstein formulated the idea of mass–energy equivalence, in 1906 Ernest Rutherford published Retardation of the α Particle from Radium in passing through matter. Hans Geiger expanded on this work in a communication to the Royal Society with experiments he and Rutherford had done, passing alpha particles through air, aluminum foil and gold leaf. More work was published in 1909 by Geiger and Ernest Marsden, in 1911–1912 Rutherford went before the Royal Society to explain the experiments and propound the new theory of the atomic nucleus as we now understand it. The plum pudding model had predicted that the particles should come out of the foil with their trajectories being at most slightly bent. But Rutherford instructed his team to look for something that shocked him to observe and he likened it to firing a bullet at tissue paper and having it bounce off. As an example, in this model consisted of a nucleus with 14 protons and 7 electrons. The Rutherford model worked well until studies of nuclear spin were carried out by Franco Rasetti at the California Institute of Technology in 1929

Electronic music
–
In general, a distinction can be made between sound produced using electromechanical means and that produced using electronic technology. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, purely electronic sound production can be achieved using devices such as the theremin, sound synthesizer, and computer. During the 1920s and 1930s, electronic instruments were introduced and the first compositions for instruments were composed. Musique concrète, created in Paris in 1948, was based on editing together recorded fragments of natural and industrial sounds, Music produced solely from electronic generators was first produced in Germany in 1953. Electronic music was created in Japan and the United States beginning in the 1950s. An important new development was the advent of computers for the purpose of composing music, algorithmic composition was first demonstrated in Australia in 1951. In America and Europe, live electronics were pioneered in the early 1960s, during the 1970s to early 1980s, the monophonic Minimoog became once the most widely used synthesizer at that time in both popular and electronic art music. In the 1980s, electronic music became dominant in popular music, with a greater reliance on synthesizers, and the adoption of programmable drum machines. Electronically produced music became prevalent in the domain by the 1990s. Contemporary electronic music includes many varieties and ranges from art music to popular forms such as electronic dance music. Today, pop music is most recognizable in its 4/4 form. At the turn of the 20th century, experimentation with emerging electronics led to the first electronic musical instruments and these initial inventions were not sold, but were instead used in demonstrations and public performances. The audiences were presented with reproductions of existing music instead of new compositions for the instruments, while some were considered novelties and produced simple tones, the Telharmonium accurately synthesized the sound of orchestral instruments. It achieved viable public interest and made progress into streaming music through telephone networks. Critics of musical conventions at the time saw promise in these developments, ferruccio Busoni encouraged the composition of microtonal music allowed for by electronic instruments. He predicted the use of machines in future music, writing the influential Sketch of a New Esthetic of Music, futurists such as Francesco Balilla Pratella and Luigi Russolo began composing music with acoustic noise to evoke the sound of machinery. They predicted expansions in timbre allowed for by electronics in the influential manifesto The Art of Noises, developments of the vacuum tube led to electronic instruments that were smaller, amplified, and more practical for performance. In particular, the theremin, ondes Martenot and trautonium were commercially produced by the early 1930s, from the late 1920s, the increased practicality of electronic instruments influenced composers such as Joseph Schillinger to adopt them

Electronic Sackbut
–
The Electronic Sackbut is an instrument designed by Hugh Le Caine in the 1940s. This compares with todays synthesizers which have one or several modulation wheels to the left of the keyboard, the controller modified volume, pitch, and timbre. Thus it was one of the first electronic instruments to use a continuous controller to modify the sound in a live situation. Such control is rare in todays electronic instruments. Le Caine began working full-time in a new lab at the National Research Council of Canada in 1954, while he developed four models of the electronic sackbut, none ever saw commercial production

Synthesizer
–
A synthesizer is an electronic musical instrument that generates electric signals that are converted to sound through instrument amplifiers and loudspeakers or headphones. Synthesizers may either imitate instruments like piano, Hammond organ, flute, vocals, natural sounds like ocean waves, etc. or generate new electronic timbres. Synthesizers without built-in controllers are called sound modules, and are controlled via USB, MIDI or CV/gate using a controller device. Synthesizers use various methods to generate electronic signals, synthesizers were first used in pop music in the 1960s. In the 1970s, synths were used in disco, especially in the late 1970s, in the 1980s, the invention of the relatively inexpensive, mass market Yamaha DX7 synth made synthesizers widely available. 1980s pop and dance music often made use of synthesizers. In the 2010s, synthesizers are used in genres of pop, rock. Contemporary classical music composers from the 20th and 21st century write compositions for synthesizer, the beginnings of the synthesizer are difficult to trace, as it is difficult to draw a distinction between synthesizers and some early electric or electronic musical instruments. One of the earliest electric musical instruments, the telegraph, was invented in 1876 by American electrical engineer Elisha Gray. He accidentally discovered the sound generation from a self-vibrating electromechanical circuit and this musical telegraph used steel reeds with oscillations created by electromagnets transmitted over a telegraph line. Gray also built a simple loudspeaker device into later models, consisting of a diaphragm in a magnetic field. This instrument was a remote electromechanical musical instrument that used telegraphy, though it lacked an arbitrary sound-synthesis function, some have erroneously called it the first synthesizer. In 1897, Thaddeus Cahill invented the Teleharmonium, which used dynamos, and was capable of additive synthesis like the Hammond organ, however, Cahills business was unsuccessful for various reasons, and similar but more compact instruments were subsequently developed, such as electronic and tonewheel organs. In 1906, American engineer, Lee De Forest ushered in the electronics age and he invented the first amplifying vacuum tube, called the Audion tube. This led to new entertainment technologies, including radio and sound films, ondes Martenot and Trautonium were continuously developed for several decades, finally developing qualities similar to later synthesizers. In the 1920s, Arseny Avraamov developed various systems of graphic sonic art, in 1938, USSR engineer Yevgeny Murzin designed a compositional tool called ANS, one of the earliest real-time additive synthesizers using optoelectronics. The earliest polyphonic synthesizers were developed in Germany and the United States, during the three years that Hammond manufactured this model,1,069 units were shipped, but production was discontinued at the start of World War II. Both instruments were the forerunners of the electronic organs and polyphonic synthesizers

Josef Tal
–
Josef Tal was an Israeli composer. He wrote three Hebrew operas, four German operas, dramatic scenes, six symphonies, thirteen concerti, chamber music and he is considered one of the founding fathers of Israeli art music. Josef Tal was born Josef Grünthal in the town of Pinne, near Poznań, soon after his birth his family, moved to Berlin, where the family managed a private orphanage. Rabbi Julius Grünthal was a docent in the Higher Institute for Jewish Studies, Tals first encounter with music was at the synagogue, where there was a choir and his grandfather served as a non-professional cantor. After attending his first concert, he began to take piano lessons, Paul Hindemith —his composition and theory teacher— introduced him to Friedrich Trautwein, who directed the electronic music studio in the building cellar. Tal completed his studies in the academy in 1931, and married dancer Rosie Löwenthal one year later and he worked giving piano lessons and accompanying dancers, singers, and silent movies. In 1934, the family immigrated to Palestine with their young son Reuven, Tal worked as a photographer in Haifa and Hadera for a short time. The family moved then to Kibbutz Beit Alpha and later to Kibbutz Gesher, finding it hard to adjust to the new social reality in the kibbutz, the family settled in Jerusalem where Tal established professional and social connections. He performed as a pianist, gave lessons and occasionally played harp with the newly founded Palestine Orchestra. In 1940 Tal married the sculptress Pola Pfeffer, in 1951 Tal was appointed Lecturer at the Hebrew University of Jerusalem and Full Professor in 1978. In 1961 he established the Centre for Electronic Music in Israel and he published academic articles, and wrote many music entries in the Encyclopaedia Hebraica. In 1965 he was appointed professor and later chairman of the Musicology Department at the Hebrew University. Tal represented Israel at the International Society for Contemporary Music conferences and in musical events. He was a member of the Berlin Academy of the Arts, until his sixties Tal appeared as a pianist and conductor with various orchestras, but his major contribution to the music world lies in his challenging compositions and his novel use of sonority. During these years his eyesight deteriorated due to macular degeneration and it increasingly difficult for him to continue composing. Using a computer screen to enlarge the music score, he managed to compose short musical works for few instruments, write his third autobiography, the complete cycle of his symphonies conducted by Israel Yinon was released on the German label CPO. He is buried in Kibbutz Maale HaHamisha, near Jerusalem, part of his archival legacy is held in the National Library of Israel in Jerusalem. Almost all of Tals works are published by the Israel Music Institute. There is no linear creative process, by its very nature it moves adventurously in many directions

UNESCO
–
The United Nations Educational, Scientific and Cultural Organization is a specialized agency of the United Nations based in Paris. It is the heir of the League of Nations International Committee on Intellectual Cooperation, UNESCO has 195 member states and nine associate members. Most of its offices are cluster offices covering three or more countries, national and regional offices also exist. UNESCO pursues its objectives through five major programs, education, natural sciences, social/human sciences, culture and it is also a member of the United Nations Development Group. UNESCO and its mandate for international cooperation can be traced back to a League of Nations resolution on 21 September 1921, on 18 December 1925, the International Bureau of Education began work as a non-governmental organization in the service of international educational development. However, the work of predecessor organizations was largely interrupted by the onset of World War II. On 30 October 1943, the necessity for an organization was expressed in the Moscow Declaration, agreed upon by China, the United Kingdom, the United States. This was followed by the Dumbarton Oaks Conference proposals of 9 October 1944, a prominent figure in the initiative for UNESCO was Rab Butler, the Minister of Education for the United Kingdom. At the ECO/CONF, the Constitution of UNESCO was introduced and signed by 37 countries, the Preparatory Commission operated between 16 November 1945, and 4 November 1946—the date when UNESCOs Constitution came into force with the deposit of the twentieth ratification by a member state. The first General Conference took place between 19 November to 10 December 1946, and elected Dr. Julian Huxley to Director-General and this change in governance distinguished UNESCO from its predecessor, the CICI, in how member states would work together in the organizations fields of competence. In 1956, the Republic of South Africa withdrew from UNESCO claiming that some of the organizations publications amounted to interference in the racial problems. South Africa rejoined the organization in 1994 under the leadership of Nelson Mandela, UNESCOs early work in the field of education included the pilot project on fundamental education in the Marbial Valley, Haiti, started in 1947. This project was followed by missions to other countries, including, for example. In 1948, UNESCO recommended that Member States should make free primary education compulsory, in 1990, the World Conference on Education for All, in Jomtien, Thailand, launched a global movement to provide basic education for all children, youths and adults. Ten years later, the 2000 World Education Forum held in Dakar, Senegal, UNESCOs early activities in culture included, for example, the Nubia Campaign, launched in 1960. The purpose of the campaign was to move the Great Temple of Abu Simbel to keep it from being swamped by the Nile after construction of the Aswan Dam, during the 20-year campaign,22 monuments and architectural complexes were relocated. This was the first and largest in a series of campaigns including Mohenjo-daro, Fes, Kathmandu, Borobudur, the organizations work on heritage led to the adoption, in 1972, of the Convention concerning the Protection of the World Cultural and Natural Heritage. The World Heritage Committee was established in 1976 and the first sites inscribed on the World Heritage List in 1978, since then important legal instruments on cultural heritage and diversity have been adopted by UNESCO member states in 2003 and 2005

University of Toronto
–
The University of Toronto is a public research university in Toronto, Ontario, Canada on the grounds that surround Queens Park. It was founded by charter in 1827 as Kings College. Originally controlled by the Church of England, the university assumed the present name in 1850 upon becoming a secular institution, as a collegiate university, it comprises twelve colleges, which differ in character and history, each with substantial autonomy on financial and institutional affairs. It has two campuses in Scarborough and Mississauga. Academically, the University of Toronto is noted for influential movements and curricula in literary criticism and communication theory, by a significant margin, it receives the most annual scientific research funding of any Canadian university. It is one of two members of the Association of American Universities outside the United States, the other being McGill University, the Varsity Blues are the athletic teams that represent the university in intercollegiate league matches, with long and storied ties to gridiron football and ice hockey. The universitys Hart House is an example of the North American student centre. The founding of a college had long been the desire of John Graves Simcoe. As an Oxford-educated military commander who had fought in the American Revolutionary War, the Upper Canada Executive Committee recommended in 1798 a college be established in York, the colonial capital. On March 15,1827, a charter was formally issued by King George IV, proclaiming from this time one College, with the style. For the education of youth in the principles of the Christian Religion, the granting of the charter was largely the result of intense lobbying by John Strachan, the influential Anglican Bishop of Toronto who took office as the colleges first president. The original three-storey Greek Revival school building was built on the present site of Queens Park, under Strachans stewardship, Kings College was a religious institution closely aligned with the Church of England and the British colonial elite, known as the Family Compact. Reformist politicians opposed the control over colonial institutions and fought to have the college secularized. Having anticipated this decision, the enraged Strachan had resigned a year earlier to open Trinity College as a private Anglican seminary, University College was created as the nondenominational teaching branch of the University of Toronto. Established in 1878, the School of Practical Science was precursor to the Faculty of Applied Science and Engineering, while the Faculty of Medicine opened in 1843, medical teaching was conducted by proprietary schools from 1853 until 1887, when the faculty absorbed the Toronto School of Medicine. Meanwhile, the university continued to set examinations and confer medical degrees, the university opened the Faculty of Law in 1887, followed by the Faculty of Dentistry in 1888, when the Royal College of Dental Surgeons became an affiliate. Women were first admitted to the university in 1884, over the next two decades, a collegiate system took shape as the university arranged federation with several ecclesiastical colleges, including Strachans Trinity College in 1904. The university operated the Royal Conservatory of Music from 1896 to 1991, the University of Toronto Press was founded in 1901 as Canadas first academic publishing house

McGill University
–
McGill University is a public research university in Montreal, Quebec, Canada. It was established in 1821 by royal charter, issued by King George IV of Great Britain, the University bears the name of James McGill, a prominent Montreal merchant from Scotland whose bequest in 1813 formed the universitys precursor, McGill College. Its academic units are organized into 11 main Faculties and Schools, McGill offers degrees and diplomas in over 300 fields of study, with the highest average admission requirements of any Canadian university. Most students are enrolled in the five largest faculties, namely Arts, Science, Medicine, Engineering, tuition fees vary significantly between in-province, out-of-province, and international students, as well as between faculties. Scholarships are generous, yet highly competitive and relatively difficult to attain, throughout its long history, McGill alumni were instrumental in inventing or initially organizing football, basketball, and ice hockey. In 1816 the RIAL was authorized to operate two new Royal Grammar Schools, in Quebec City and in Montreal and this was an important first step in the creation of nondenominational schools. When James McGill died in 1813 his bequest was administered by the RIAL, the original two Royal Grammar Schools closed in 1846 and by the mid-19th century the RIAL lost control of the other 82 grammar schools it had administered. Its sole remaining purpose was to administer the McGill bequest on behalf of the private college, since the revised Royal Charter of 1852, The Trustees of the RIAL comprise the Board of Governors of McGill University. James McGill, born in Glasgow, Scotland on 6 October 1744, was a merchant in Quebec. Between 1811 and 1813, he drew up a will leaving his Burnside estate, a 19-hectare tract of rural land and 10,000 pounds to the Royal Institution for the Advancement of Learning. As a condition of the bequest, the land and funds had to be used for the establishment of a University or College, for the purposes of Education and the Advancement of Learning in the said Province. On March 31,1821, after protracted battles with the Desrivières family. The Charter provided that the College should be deemed and taken as a University, the Faculty of Medicine granted its first degree, a Doctor of Medicine and Surgery, in 1833, this was also the first medical degree to be awarded in Canada. The Faculty of Medicine remained the only functioning faculty until 1843 when the Faculty of Arts commenced teaching in the newly constructed Arts Building. The university also historically has strong linkage with The Canadian Grenadier Guards and this title is marked upon the stone that stands before the Arts building, from where the Guards step off annually to commemorate Remembrance Day. The Faculty of Law was founded in 1848 which is also the oldest of its kind in the nation,48 years later, the school of architecture at McGill University was founded. Sir John William Dawson, McGills principal from 1855 to 1893, is credited with transforming the school into a modern university. He recruited the aid of Montreals wealthiest citizens, many of whom donated property and their names adorn many of the campuss prominent buildings

Ostinato
–
In music, an ostinato is a motif or phrase that persistently repeats in the same musical voice, usually at the same pitch. The repeating idea may be a pattern, part of a tune. Both ostinatos and ostinati are accepted English plural forms, the reflecting the words Italian etymology. If the cadence may be regarded as the cradle of tonality, within the context of film music, Claudia Gorbman defines an obstinate as a repeated melodic or rhythmic figure that propel scenes that lack dynamic visual action. Ostinato plays an important part in improvised music, in which it is referred to as a riff or a vamp. A favorite technique of contemporary writers, ostinati are often used in modal and Latin jazz. Ostinato are used in 20th-century music to stabilize groups of pitches, as in Stravinskys The Rite of Spring Introduction and Augurs of Spring. A famous type of ostinato, called the Rossini crescendo, owes its name to a crescendo that underlies a persistent musical pattern and this style was emulated by other bel canto composers, especially Vincenzo Bellini, and later by Wagner. Applicable in homophonic and contrapuntal textures they are repetitive rhythmic-harmonic schemes, more familiar as accompanimental melodies, the techniques appeal to composers from Debussy to avant-garde composers until at least the 1970s. Lies in part in the need for unity created by the abandonment of functional chord progressions to shape phrases. Relentless, repetitive character help to establish and confirm the modal center and their popularity may also be justified by their ease as well as range of use, though. Ostinato must be employed judiciously, as its overuse can lead to monotony. Ground bass or basso ostinato is a type of form in which a bass line. Aaron Copland describes basso ostinato as, the easiest to recognize of the variation forms wherein. A long phrase—either an accompanimental figure or an actual melody—is repeated over and over again in the bass part, however, he cautions, it might more properly be termed a musical device than a musical form. Many instruments south of the Sahara Desert play ostinato melodies and these include lamellophones such as the mbira, as well as xylophones like the balafon, the bikutsi, and the gyil. Ostinato figures are also played on string instruments such as the kora, gankoqui bell ensembles, often, African ostinatos contain offbeats or cross-beats, that contradict the metric structure. Other African ostinatos generate complete cross-rhythms by sounding both the main beats and cross-beats, in the following example, a gyil sounds the three-against-two cross-rhythm

Arpeggio
–
A broken chord is a chord broken into a sequence of notes. A broken chord may repeat some of the notes from the chord, an arpeggio is a type of broken chord where the notes that compose a chord are played or sung in a rising or descending order. An arpeggio may also more than one octave. The word arpeggio comes from the Italian word arpeggiare, which means to play on a harp, even though the notes of an arpeggio are not played or sung all together at the same time, listeners hear the sequence of notes as forming a chord. When an arpeggio also contains passing tones that are not part of the chord, Arpeggios enable composers writing for monophonic instruments that play one note at a time, to voice chords and chord progressions in musical pieces. Arpeggios and broken chords are used to help create rhythmic interest. A notable example of which is the Alberti bass figuration which was used in piano music from the Classical music period. With an Alberti bass, rather play the notes of a chord all at once. An arpeggio is a group of notes which are played one after the other, executing an arpeggio requires the player to play the sounds of a chord individually to differentiate the notes. The notes all belong to one chord, the chord may, for example, be a simple chord with the 1st, 3rd, and 5th notes of the scale in it. An arpeggio for the chord of C major going up two octaves would be the notes, an arpeggio is a type of broken chord. Other types of broken chords play chord notes out of sequence or more than one note, Arpeggios can rise or fall for more than one octave. Students of musical instruments and singers learn how to play and sing scales and they are often a requirement for music examinations. An arpeggiated chord means a chord which is spread, i. e. the notes are not played at the same time, arpeggiated chords are often used in harp and piano music. An arpeggiated chord may be written with a vertical line in front of the chord. It is spread from the lowest to the highest note, occasionally, composers such as Béla Bartók have asked for them to be played from top to bottom. This is shown by adding an arrow pointing down, some ostinato figures consist of arpeggios. Any instrument may employ arpeggiation, but the instruments use arpeggios most often

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

Integrated Authority File
–
The Integrated Authority File or GND is an international authority file for the organisation of personal names, subject headings and corporate bodies from catalogues. It is used mainly for documentation in libraries and increasingly also by archives, the GND is managed by the German National Library in cooperation with various regional library networks in German-speaking Europe and other partners. The GND falls under the Creative Commons Zero license, the GND specification provides a hierarchy of high-level entities and sub-classes, useful in library classification, and an approach to unambiguous identification of single elements. It also comprises an ontology intended for knowledge representation in the semantic web, available in the RDF format

MusicBrainz
–
MusicBrainz is a project that aims to create an open data music database that is similar to the freedb project. MusicBrainz was founded in response to the placed on the Compact Disc Database. MusicBrainz has expanded its goals to reach beyond a compact disc metadata storehouse to become an open online database for music. MusicBrainz captures information about artists, their works, and the relationships between them. Recorded works entries capture at a minimum the album title, track titles, and these entries are maintained by volunteer editors who follow community written style guidelines. Recorded works can also store information about the date and country. As of 26 July 2016, MusicBrainz contained information about roughly 1.1 million artists,1.6 million releases, end-users can use software that communicates with MusicBrainz to add metadata tags to their digital media files, such as MP3, Ogg Vorbis or AAC. As with other contributions, the MusicBrainz community is in charge for maintaining and reviewing the data, besides collecting metadata about music, MusicBrainz also allows looking up recordings by their acoustic fingerprint. A separate application, such as MusicBrainz Picard, must be used for this, in 2000, MusicBrainz started using Relatables patented TRM for acoustic fingerprint matching. This feature attracted many users and allowed the database to grow quickly, however, by 2005 TRM was showing scalability issues as the number of tracks in the database had reached into the millions. This issue was resolved in May 2006 when MusicBrainz partnered with MusicIP, tRMs were phased out and replaced by MusicDNS in November 2008. In October 2009 MusicIP was acquired by AmpliFIND, some time after the acquisition, the MusicDNS service began having intermittent problems. Since the future of the free service was uncertain, a replacement for it was sought. The Chromaprint acoustic fingerprinting algorithm, the basis for AcoustID identification service, was started in February 2010 by a long-time MusicBrainz contributor Lukáš Lalinský, while AcoustID and Chromaprint are not officially MusicBrainz projects, they are closely tied with each other and both are open source. Chromaprint works by analyzing the first two minutes of a track, detecting the strength in each of 12 pitch classes, storing these 8 times per second, additional post-processing is then applied to compress this fingerprint while retaining patterns. The AcoustID search server then searches from the database of fingerprints by similarity, since 2003, MusicBrainzs core data are in the public domain, and additional content, including moderation data, is placed under the Creative Commons CC-BY-NC-SA-2.0 license. The relational database management system is PostgreSQL, the server software is covered by the GNU General Public License. The MusicBrainz client software library, libmusicbrainz, is licensed under the GNU Lesser General Public License, in December 2004, the MusicBrainz project was turned over to the MetaBrainz Foundation, a non-profit group, by its creator Robert Kaye

Virtual International Authority File
–
The Virtual International Authority File is an international authority file. It is a joint project of national libraries and operated by the Online Computer Library Center. The project was initiated by the US Library of Congress, the German National Library, the National Library of France joined the project on October 5,2007. The project transitions to a service of the OCLC on April 4,2012, the aim is to link the national authority files to a single virtual authority file. In this file, identical records from the different data sets are linked together, a VIAF record receives a standard data number, contains the primary see and see also records from the original records, and refers to the original authority records. The data are available online and are available for research and data exchange. Reciprocal updating uses the Open Archives Initiative Protocol for Metadata Harvesting protocol, the file numbers are also being added to Wikipedia biographical articles and are incorporated into Wikidata. VIAFs clustering algorithm is run every month, as more data are added from participating libraries, clusters of authority records may coalesce or split, leading to some fluctuation in the VIAF identifier of certain authority records
