China the People's Republic of China, is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering 9,600,000 square kilometers, it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, the special administrative regions of Hong Kong and Macau. China emerged as one of the world's earliest civilizations, in the fertile basin of the Yellow River in the North China Plain. For millennia, China's political system was based on hereditary monarchies, or dynasties, beginning with the semi-legendary Xia dynasty in 21st century BCE. Since China has expanded, re-unified numerous times. In the 3rd century BCE, the Qin established the first Chinese empire; the succeeding Han dynasty, which ruled from 206 BC until 220 AD, saw some of the most advanced technology at that time, including papermaking and the compass, along with agricultural and medical improvements.
The invention of gunpowder and movable type in the Tang dynasty and Northern Song completed the Four Great Inventions. Tang culture spread in Asia, as the new Silk Route brought traders to as far as Mesopotamia and Horn of Africa. Dynastic rule ended in 1912 with the Xinhai Revolution; the Chinese Civil War resulted in a division of territory in 1949, when the Communist Party of China established the People's Republic of China, a unitary one-party sovereign state on Mainland China, while the Kuomintang-led government retreated to the island of Taiwan. The political status of Taiwan remains disputed. Since the introduction of economic reforms in 1978, China's economy has been one of the world's fastest-growing with annual growth rates above 6 percent. According to the World Bank, China's GDP grew from $150 billion in 1978 to $12.24 trillion by 2017. Since 2010, China has been the world's second-largest economy by nominal GDP and since 2014, the largest economy in the world by purchasing power parity.
China is the world's largest exporter and second-largest importer of goods. China is a recognized nuclear weapons state and has the world's largest standing army and second-largest defense budget; the PRC is a permanent member of the United Nations Security Council as it replaced the ROC in 1971, as well as an active global partner of ASEAN Plus mechanism. China is a leading member of numerous formal and informal multilateral organizations, including the Shanghai Cooperation Organization, WTO, APEC, BRICS, the BCIM, the G20. In recent times, scholars have argued that it will soon be a world superpower, rivaling the United States; the word "China" has been used in English since the 16th century. It is not a word used by the Chinese themselves, it has been traced through Portuguese and Persian back to the Sanskrit word Cīna, used in ancient India."China" appears in Richard Eden's 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. Barbosa's usage was derived from Persian Chīn, in turn derived from Sanskrit Cīna.
Cīna was first used including the Mahābhārata and the Laws of Manu. In 1655, Martino Martini suggested that the word China is derived from the name of the Qin dynasty. Although this derivation is still given in various sources, it is complicated by the fact that the Sanskrit word appears in pre-Qin literature; the word may have referred to a state such as Yelang. The meaning transferred to China as a whole; the origin of the Sanskrit word is still a matter of debate, according to the Oxford English Dictionary. The official name of the modern state is the "People's Republic of China"; the shorter form is "China" Zhōngguó, from zhōng and guó, a term which developed under the Western Zhou dynasty in reference to its royal demesne. It was applied to the area around Luoyi during the Eastern Zhou and to China's Central Plain before being used as an occasional synonym for the state under the Qing, it was used as a cultural concept to distinguish the Huaxia people from perceived "barbarians". The name Zhongguo is translated as "Middle Kingdom" in English.
Archaeological evidence suggests that early hominids inhabited China between 2.24 million and 250,000 years ago. The hominid fossils of Peking Man, a Homo erectus who used fire, were discovered in a cave at Zhoukoudian near Beijing; the fossilized teeth of Homo sapiens have been discovered in Fuyan Cave in Hunan. Chinese proto-writing existed in Jiahu around 7000 BCE, Damaidi around 6000 BCE, Dadiwan from 5800–5400 BCE, Banpo dating from the 5th millennium BCE; some scholars have suggested. According to Chinese tradition, the first dynasty was the Xia, which emerged around 2100 BCE; the dynasty was considered mythical by historians until scientific excavations found early Bronze Age sites at Erlitou, Henan in 1959. It remains unclear whether these sites are the remains of the Xia dynasty or of another culture from the same period; the succeeding Shang dynasty is the earliest to be confirmed by contemporary records. The Shang ruled the plain of the Yellow River in eastern China from the 17th to the 11th century BCE.

Indian Institute of Management Bangalore
Indian Institute of Management Bangalore is a public management school and an Institute of National Importance located in Bangalore, India. Founded in 1973, it was the third IIM to be established, after IIM Ahmedabad, it offers Post Graduate and executive training programmes. The Post Graduate Programme in Management, a two-year, full-time residential MBA programme is IIMB's flagship programme. In addition to its main academic programmes, IIMB is engaged in facilitating research, offering consultant services, conducting seminars and academic conferences and publishing journals. In 1972, a committee headed by Ravi J. Matthai, seeing the rising demand for graduates of the first two IIMs namely IIM Calcutta and IIM Ahmedabad, recommended the need to have two more IIMs. While the first two IIMs were oriented towards the private sector, it was decided that the new institutions shall be oriented towards public sector to cater to its growing needs of management graduates; the Institute at Bangalore was set up next year, designed to cater to the needs of public sector enterprises.
For the proposed institute, the Government of Karnataka offered 100 acres of land free of cost and a contribution of ₹3 million. T. A. Pai and N. S. Ramaswamy were appointed as director respectively; the institute was inaugurated by Indira Gandhi, the Prime Minister of India, on 28 October 1973. The institute was started in St. Joseph's College of Commerce, some other buildings, which were rented; the new institute came up at Bannerghatta Road in South Bangalore. The motto derived from Sanskrit तेजस्वि नावधीतमस्तु is an extract from the Shanti Mantra recited in Taittiriya Upanishad, Katha Upanishad, Mandukya Upanishad and Shvetashvatara Upanishad; the motto translates to May our study be effective. Prior to 2018, IIM Bangalore awarded diplomas instead of degrees because IIMs were not set up as universities through an act of parliament but as societies under the Societies Act; the Indian Institutes of Management Act, 2017 enacted by the Ministry of Human Resource Development in December 2017 declared IIMs as Institutes of National Importance, thereby allowing IIMs to award degrees to their students instead of diplomas.
In 2018, IIM Bangalore became the first IIM to award MBA degree to the graduates of the Post Graduate Programme in Management. Worldwide, the Financial Times has ranked IIM Bangalore #19 in its Masters in Management Ranking 2016 and #49 in its Global MBA Ranking 2017; the QS Global MBA Rankings 2019 ranked it #71 in the world and #9 in the QS Global MBA Rankings 2019: Asia. The QS Global EMBA Rankings 2018 ranked it at #63. IIM Bangalore’s one-year full-time Executive Post Graduate Programme in Management has been ranked among the top 35 in the Financial Times Global MBA Ranking 2019 for the second consecutive year. In India, IIMB was ranked #1 among management schools by the National Institutional Ranking Framework in 2019, it was ranked third by Business Today's "India's best B-schools 2016". IIM Bangalore mentored IIM Trichy when it was established in 2011, it mentors IIM Visakhapatnam from its establishment in 2015. IIM Visakhapatnam operates from temporary campus inside Andhra University, it follows similar PGP program with faculty coming from IIM Bangalore.
The current campus located at Bannerghatta Road in Bengaluru was designed by Prtizker prize-winning architect B. V. Doshi and was completed in 1983; the campus occupying an area of over 100-acres is located in South Bangalore. IIMB is known for lush woods; the academic blocks were designed by Stein, Doshi & Balla architects led by B. V. Doshi and were completed by 1983. A few blocks were added owing to the increase in the number of students being enrolled. There are blocks lettered from A to P where classes, faculty offices and other administrative entities are located; the classes are air conditioned with state of art facilities. The library is housed in a 55,000 square feet complex consisting of four floors; this automated state of art facility consists of about 235,000 documents and books apart from 85,000 journals are available for reference. The library subscribes to 27 newspapers and more than 200 newsletters. IIMB consists of 16 hostel blocks apart from one executive block and the executive accommodation at the Management Development Centre.
The hostel consists of 16 blocks named from A to P. IIMB has separate facilities for soccer, tennis, volleyball, table tennis and pool. An integrated indoor sports complex with a swimming pool is available; the Auditorium is situated within the academic blocks. It has a seating capacity of 500 people and plays host to various events and guest lectures held at the institute; the institute has a 24-hour Internet connectivity with workstations.

The Academic Council is an elected body that facilitates the management of the academic system at IIM Bangalore. The Council acts as the interface between students and faculty and is responsible
Australia the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area; the neighbouring countries are Papua New Guinea and East Timor to the north. The population of 25 million is urbanised and concentrated on the eastern seaboard. Australia's capital is Canberra, its largest city is Sydney; the country's other major metropolitan areas are Melbourne, Brisbane and Adelaide. Australia was inhabited by indigenous Australians for about 60,000 years before the first British settlement in the late 18th century, it is documented. After the European exploration of the continent by Dutch explorers in 1606, who named it New Holland, Australia's eastern half was claimed by Great Britain in 1770 and settled through penal transportation to the colony of New South Wales from 26 January 1788, a date which became Australia's national day; the population grew in subsequent decades, by the 1850s most of the continent had been explored and an additional five self-governing crown colonies established.
On 1 January 1901, the six colonies federated. Australia has since maintained a stable liberal democratic political system that functions as a federal parliamentary constitutional monarchy, comprising six states and ten territories. Being the oldest and driest inhabited continent, with the least fertile soils, Australia has a landmass of 7,617,930 square kilometres. A megadiverse country, its size gives it a wide variety of landscapes, with deserts in the centre, tropical rainforests in the north-east and mountain ranges in the south-east. A gold rush began in Australia in the early 1850s, its population density, 2.8 inhabitants per square kilometre, remains among the lowest in the world. Australia generates its income from various sources including mining-related exports, telecommunications and manufacturing. Indigenous Australian rock art is the oldest and richest in the world, dating as far back as 60,000 years and spread across hundreds of thousands of sites. Australia is a developed country, with the world's 14th-largest economy.
It has a high-income economy, with the world's tenth-highest per capita income. It is a regional power, has the world's 13th-highest military expenditure. Australia has the world's ninth-largest immigrant population, with immigrants accounting for 26% of the population. Having the third-highest human development index and the eighth-highest ranked democracy globally, the country ranks in quality of life, education, economic freedom, civil liberties and political rights, with all its major cities faring well in global comparative livability surveys. Australia is a member of the United Nations, G20, Commonwealth of Nations, ANZUS, Organisation for Economic Co-operation and Development, World Trade Organization, Asia-Pacific Economic Cooperation, Pacific Islands Forum and the ASEAN Plus Six mechanism; the name Australia is derived from the Latin Terra Australis, a name used for a hypothetical continent in the Southern Hemisphere since ancient times. When Europeans first began visiting and mapping Australia in the 17th century, the name Terra Australis was applied to the new territories.
Until the early 19th century, Australia was best known as "New Holland", a name first applied by the Dutch explorer Abel Tasman in 1644 and subsequently anglicised. Terra Australis still saw occasional usage, such as in scientific texts; the name Australia was popularised by the explorer Matthew Flinders, who said it was "more agreeable to the ear, an assimilation to the names of the other great portions of the earth". The first time that Australia appears to have been used was in April 1817, when Governor Lachlan Macquarie acknowledged the receipt of Flinders' charts of Australia from Lord Bathurst. In December 1817, Macquarie recommended to the Colonial Office. In 1824, the Admiralty agreed that the continent should be known by that name; the first official published use of the new name came with the publication in 1830 of The Australia Directory by the Hydrographic Office. Colloquial names for Australia include "Oz" and "the Land Down Under". Other epithets include "the Great Southern Land", "the Lucky Country", "the Sunburnt Country", "the Wide Brown Land".
The latter two both derive from Dorothea Mackellar's 1908 poem "My Country". Human habitation of the Australian continent is estimated to have begun around 65,000 to 70,000 years ago, with the migration of people by land bridges and short sea-crossings from what is now Southeast Asia; these first inhabitants were the ancestors of modern Indigenous Australians. Aboriginal Australian culture is one of the oldest continual civilisations on earth. At the time of first European contact, most Indigenous Australians were hunter-gatherers with complex economies and societies. Recent archaeological finds suggest. Indigenous Australians have an oral culture with spiritual values based on reverence for the land and a belief in the Dreamtime; the Torres Strait Islanders, ethnically Melanesian, obtained their livelihood from seasonal horticulture and the resources of their reefs and seas. The northern coasts and waters of Australia were visited s

The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
White is the lightest color and is achromatic. It is the color of fresh snow and milk, is the opposite of black. White objects reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red and green light. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, Romans wore a white toga as a symbol of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, a white lamb sacrifice and purity, it was the royal color of the Kings of France, of the monarchist movement that opposed the Bolsheviks during the Russian Civil War. Greek and Roman temples were faced with white marble, beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches and other government buildings in the United States, it was widely used in 20th century modern architecture as a symbol of modernity and simplicity. According to surveys in Europe and the United States, white is the color most associated with perfection, the good, cleanliness, the beginning, the new and exactitude.
White is an important color for all world religions. The Pope, the head of the Roman Catholic Church, has worn white since 1566, as a symbol of purity and sacrifice. In Islam, in the Shinto religion of Japan, it is worn by pilgrims. In Western cultures and in Japan, white is the most common color for wedding dresses, symbolizing purity and virginity. In many Asian cultures, white is the color of mourning; the word white continues Old English hwīt from a Common Germanic *χwītaz reflected in OHG wîz, ON hvítr, Goth. ƕeits. The root is from Proto-Indo-European language *kwid-, surviving in Sanskrit śveta "to be white or bright" and Slavonic světŭ "light"; the Icelandic word for white, hvítur, is directly derived from the Old Norse form of the word hvítr. Common Germanic had the word *blankaz, borrowed into Late Latin as *blancus, which provided the source for Romance words for "white"; the antonym of white is black. Some non-European languages have a wide variety of terms for white; the Inuit language has seven different words for seven different nuances of white.
Sanskrit has specific words for bright white, the white of teeth, the white of sandalwood, the white of the autumn moon, the white of silver, the white of cow's milk, the white of pearls, the white of a ray of sunlight, the white of stars. Japanese has six different words, depending upon brilliance or dullness, or if the color is inert or dynamic. White was one of the first colors used in art; the Lascaux Cave in France contains drawings of bulls and other animals drawn by paleolithic artists between 18,000 and 17,000 years ago. Paleolithic artists used calcite or chalk, sometimes as a background, sometimes as a highlight, along with charcoal and red and yellow ochre in their vivid cave paintings. In ancient Egypt, white was connected with the goddess Isis; the priests and priestesses of Isis dressed only in white linen, it was used to wrap mummies. In Greece and other ancient civilizations, white was associated with mother's milk. In Greek mythology, the chief god Zeus was nourished at the breast of the nymph Amalthea.
In the Talmud, milk was one of four sacred substances, along with wine and the rose. The ancient Greeks saw the world in terms of darkness and light, so white was a fundamental color. According to Pliny the Elder in his Natural History and the other famous painters of ancient Greece used only four colors in their paintings. A plain white toga, known as a toga virilis, was worn for ceremonial occasions by all Roman citizens over the age of 14–18. Magistrates and certain priests wore a toga praetexta, with a broad purple stripe. In the time of the Emperor Augustus, no Roman man was allowed to appear in the Roman forum without a toga; the ancient Romans had two words for white. A man who wanted public office in Rome wore a white toga brightened with chalk, called a toga candida, the origin of the word candidate; the Latin word candere meant to be bright. It was the origin of the words candid. In ancient Rome, the priestesses of the goddess Vesta dressed in white linen robes, a white palla or shawl, a white veil.
They protected the penates of Rome. White symbolized their purity and chastity; the early Christian church adopted the Roman symbolism of white as the color of purity and virtue. It became the color worn by priests during Mass, the color worn by monks of the Cistercian Order, under Pope Pius V, a former monk of the Dominican Order, it became the official color worn by the pope himself. Monks of the Order of Saint Benedict dressed in the white or gray of natural undyed wool, but changed to black, the color of humility and penitence. Postclassical history art, the white lamb became the symbol of the sacrifice of Christ on behalf of mankind. John the Baptist described Christ as the lamb of God; the white lamb was the center of one of the most famous paintings of the Medieval period, the Ghent Altarpiece by Jan van Eyck. White was the symbolic color of the transfiguration; the Gospel of Saint Mark describes Jesus' clothing in this event as "shining, exceeding white as snow." Artists such as Fra Angelico used their skill
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between green on the spectrum of visible light; the eye perceives blue when observing light with a dominant wavelength between 450 and 495 nanometres. Most blues contain a slight mixture of other colours; the clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called. Distant objects appear. Blue has been an important colour in decoration since ancient times; the semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments. In the eighth century Chinese artists used cobalt blue to white porcelain. In the Middle Ages, European artists used it in the windows of Cathedrals. Europeans wore clothing coloured with the vegetable dye woad until it was replaced by the finer indigo from America.
In the 19th century, synthetic blue dyes and pigments replaced mineral pigments and synthetic dyes. Dark blue became a common colour for military uniforms and in the late 20th century, for business suits; because blue has been associated with harmony, it was chosen as the colour of the flags of the United Nations and the European Union. Surveys in the US and Europe show that blue is the colour most associated with harmony, confidence, infinity, the imagination and sometimes with sadness. In US and European public opinion polls it is the most popular colour, chosen by half of both men and women as their favourite colour; the same surveys showed that blue was the colour most associated with the masculine, just ahead of black, was the colour most associated with intelligence, knowledge and concentration. Blue is the colour of light between green on the visible spectrum. Hues of blue include ultramarine, closer to violet. Blue varies in shade or tint. Darker shades of blue include ultramarine, cobalt blue, navy blue, Prussian blue.
Blue pigments were made from minerals such as lapis lazuli and azurite, blue dyes were made from plants. Today most blue dyes are made by a chemical process; the modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao. In heraldry, the word azure is used for blue. In Russian and some other languages, there is no single word for blue, but rather different words for light blue and dark blue. See Colour term. Several languages, including Japanese, Thai and Lakota Sioux, use the same word to describe blue and green. For example, in Vietnamese the colour of both tree leaves and the sky is xanh. In Japanese, the word for blue is used for colours that English speakers would refer to as green, such as the colour of a traffic signal meaning "go". Linguistic research indicates. Colour names developed individually in natural languages beginning with black and white, adding red, only much – as the last main category of colour accepted in a language – adding the colour blue when blue pigments could be manufactured reliably in the culture using that language.
Human eyes perceive blue when observing light which has a dominant wavelength of 450–495 nanometres. Blues with a higher frequency and thus a shorter wavelength look more violet, while those with a lower frequency and a longer wavelength appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres. Isaac Newton included blue as one of the seven colours in his first description the visible spectrum, He chose seven colours because, the number of notes in the musical scale, which he believed was related to the optical spectrum, he included indigo, the hue between blue and violet, as one of the separate colours, though today it is considered a hue of blue. In painting and traditional colour theory, blue is one of the three primary colours of pigments, which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet and yellow together form green. Mixing all three primary colours together produces a dark grey. From the Renaissance onwards, painters used this system to create their colours.
The RYB model was used for colour printing by Jacob Christoph Le Blon as early as 1725. Printers discovered that more accurate colours could be created by using combinations of magenta, cyan and black ink, put onto separate inked plates and overlaid one at a time onto paper; this method could produce all the colours in the spectrum with reasonable accuracy. In the 19th century the Scottish physicist James Clerk Maxwell found a new way of explaining colours, by the wa
