List of Puerto Rican-American communities

The South is home to 1.3 million Puerto Ricans, comprising 29% of the Puerto Rican population nationwide. Florida is home to two-thirds of the Puerto Rican population in the South. Florida is currently home to the fastest-growing Puerto Rican population of any state. Cubans and Puerto Ricans are Florida's largest Hispanic groups, though unlike the Cuban community which is nearly entirely located in the South Florida and Tampa Bay areas, the Puerto Rican population is far more spread-out and is present in large numbers in Central Florida, South Florida, and North Florida, having large populations in the metro areas of Orlando, Tampa, Miami, and Jacksonville, among other cities. South Florida has a large Puerto Rican population centered around the Miami metro area, yet are largely overlooked by Cuban dominance and the overall diversity of the Miami area, with large numbers in Miami, Hollywood, West Palm Beach, Homestead, North Miami, Boynton Beach, Coconut Creek, and Port St. Lucie. The westcoast of Florida has significant Puerto Rican populations present in scattered areas, in cities such as, Tampa, St. Petersburg, Pinellas Park, Lakeland, Cape Coral, Lehigh Acres, and Fort Myers. Central Florida has the largest Puerto Rican population of any region in the state and the fastest-growing Puerto Rican population in the country. The Orlando metropolitan area is the center of the Puerto Rican population in Central Florida and there is large populations of Puerto Ricans throughout the region, with the largest populations in Orlando, Kissimmee, Poinciana, Buenaventura Lakes, Azalea Park, Meadow Woods, Pine Hills, Deltona, St. Cloud, Sanford, Apopka, Alafaya, Oak Ridge, Oviedo, Daytona Beach, and Palm Bay. Osceola County is the only county in the country where Puerto Ricans are the largest ancestral group. Puerto Ricans are also the vast majority of Hispanics in Volusia County. The I-4 corridor, extending from Daytona Beach to Tampa, is home to 500,000 Puerto Ricans. The I-4 corridor is politically considered the swing section of the state, yet Puerto Rican growth has created a Democratic registration advantage. Puerto Rican growth in Central Florida has also had a direct impact on the uninterrupted influence Cubans once had. In North Florida, there are significant Puerto Rican populations in Jacksonville, Orange Park, Ocala, Tallahassee, and Gainesville. Though, the most notable growth in North Florida has been in Clay County and the Jacksonville area. Though, the Puerto Rican population may not be as large as other parts of Florida, especially Central Florida, Puerto Ricans often make up the majority of Hispanics in many North Florida cities, due to lower percentages of Hispanics in North Florida.

In the 18th century, the term civil engineering was coined to incorporate all things civilian as opposed to military engineering. The first self-proclaimed civil engineer was John Smeaton, who constructed the Eddystone Lighthouse. In 1771 Smeaton and some of his colleagues formed the Smeatonian Society of Civil Engineers, a group of leaders of the profession who met informally over dinner. Though there was evidence of some technical meetings, it was little more than a social society.In 1818 the Institution of Civil Engineers was founded in London, and in 1820 the eminent engineer Thomas Telford became its first president. The institution received a Royal Charter in 1828, formally recognising civil engineering as a profession. Its charter defined civil engineering as:

Originally a Adivasi (tribal) goddess, Manasa was accepted in the pantheon worshipped by Hindus. Later, she was included in higher caste Hindu pantheon, where she is now regarded as a Hindu goddess rather than a tribal one. As a Hindu goddess, she was recognized as a daughter of sage Kashyapa and Kadru, the mother of all Nāgas. By the 14th century, Manasa was identified as the goddess of fertility and marriage rites and was assimilated into the Shaiva pantheon, related to the god, Shiva. Myths glorified her by describing that she saved Shiva after he drank the poison, and venerated her as the "remover of poison". Her popularity grew and spread to southern India, and her followers began to rival Shaivism (the cult of Shiva). As a consequence, stories attributing Manasa's birth to Shiva emerged and ultimately Shaivism adopted this indigenous goddess into the Brahmanical tradition of mainstream Hinduism.

The liver is a reddish-brown, wedge-shaped organ with four lobes of unequal size and shape. A human liver normally weighs approximately 1.5 kg (3.3 lb), and has a width of about 15 cm (6 in). It is both the heaviest internal organ and the largest gland in the human body. Located in the right upper quadrant of the abdominal cavity, it rests just below the diaphragm, to the right of the stomach and overlies the gallbladder.

Ada Lovelace's work for Charles Babbage's Analytical Engine in the 19th century is often considered the founding of the discipline, though both mathematicians' efforts remained theoretical only, as the technology of Babbage's day proved insufficient to build his computer. Alan Turing is credited with being the first person to come up with a theory for software in 1935, which led to the two academic fields of computer science and software engineering.

The elephants are the large mammals forming the family Elephantidae in the order Proboscidea. Three species are currently recognised: the African bush elephant ("Loxodonta africana"), the African forest elephant ("L. cyclotis"), and the Asian elephant ("Elephas maximus"). Elephants are scattered throughout sub-Saharan Africa, South Asia, and Southeast Asia. Elephantidae is the only surviving family of the order Proboscidea; other, now extinct, members of the order include deinotheres, gomphotheres, mammoths, and mastodons.

This period, known as the Dark Ages, began around 377,000 years after the Big Bang. During the Dark Ages, the temperature of the universe cooled from some 4000 K down to about 60 K, and only two sources of photons existed: the photons released during recombination/decoupling (as neutral hydrogen atoms formed), which we can still detect today as the cosmic microwave background (CMB), and photons occasionally released by neutral hydrogen atoms, known as the 21 cm spin line of neutral hydrogen. The hydrogen spin line is in the microwave range of frequencies, and within 3 million years, the CMB photons had redshifted out of visible light to infrared; from that time until the first stars, there were no visible light photons. Other than perhaps some rare statistical anomalies, the universe was truly dark.

In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper.  The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. The first electronic printer was the EP-101, invented by Japanese company Epson and released in 1968. The first commercial printers generally used mechanisms from electric typewriters and Teletype machines. The demand for higher speed led to the development of new systems specifically for computer use. In the 1980s were daisy wheel systems similar to typewriters, line printers that produced similar output but at much higher speed, and dot matrix systems that could mix text and graphics but produced relatively low-quality output. The plotter was used for those requiring high quality line art like blueprints.

Until the mid-18th century, charity was mainly distributed through parish relief (such as the English Poor Laws of 1601), churches, almshouses and bequests from the rich. Both Christianity and Islam incorporated significant charitable elements from their very beginnings and "dāna" (alms-giving) has a long tradition in Hinduism, Jainism, Buddhism and Sikhism. Charities provided education, health, housing and even prisons. Almshouses were established throughout Europe in the Early Middle Ages to provide a place of residence for poor, old and distressed people; King Athelstan of England (reigned 924-939) founded the first recorded almshouse in York in the 10th century.

There have recently been discoveries of tortoise-shell carvings dating back to c. 6000 BC, like Jiahu Script, Banpo Script, but whether or not the carvings are complex enough to qualify as writing is under debate. At Damaidi in the Ningxia Hui Autonomous Region, 3,172 cliff carvings dating to 6000–5000 BC have been discovered, featuring 8,453 individual characters, such as the sun, moon, stars, gods, and scenes of hunting or grazing. These pictographs are reputed to be similar to the earliest characters confirmed to be written Chinese. If it is deemed to be a written language, writing in China will predate Mesopotamian cuneiform, long acknowledged as the first appearance of writing, by some 2,000 years; however it is more likely that the inscriptions are rather a form of proto-writing, similar to the contemporary European Vinca script.

In biology, a pathogen ( "pathos" "suffering, passion" and -γενής "-genēs" "producer of") is also known as an infectious agent, or a germ. In the oldest and broadest sense, a pathogen is anything that can produce disease; the term came into use in the 1880s. Typically the term pathogen is used to describe an "infectious" microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. Small animals, such as certain kinds of worms and insect larvae, can also produce disease but such animals are usually, in common parlance, referred to as parasites rather than pathogens. The scientific study of microscopic, pathogenic organisms is called microbiology, while the study of disease that may include these pathogens is called pathology. Parasitology, meanwhile, is the scientific study of parasites and the organisms that host them.

In short, their analysis showed that in a culture with only two terms, they would roughly correlate with "dark" (covering black, dark colors, and cold colors such as blue) and "bright" (covering white, light colors, and warm colors such as red). All languages with three colors terms would add red to this distinction. Thus, the three most basic colors are black, white, and red. Additional color terms are added in a fixed order as a language evolves: first one of green or yellow; then the other of green or yellow; then blue. All languages distinguishing six colors contain terms for black, white, red, green, yellow, and blue. These colors roughly correspond to the sensitivities of the retinal ganglion cells, leading Berlin and Kay to argue that color naming is not merely a cultural phenomenon, but is one that is also constrained by biology—that is, language is shaped by perception. A 2012 study suggested that the origin of this hierarchy may be tied to human vision and the time ordering in which these color names get accepted or agreed upon in a population perfectly matches the order predicted by the hierarchy.

Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build, and test machines, systems, structures and materials to fulfill objectives and requirements while considering the limitations imposed by practicality, regulation, safety, and cost. The word "engineer" (Latin "ingeniator") is derived from the Latin words "ingeniare" ("to create, generate, contrive, devise") and "ingenium" ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional practice (culminating in a project report or thesis) and passage of engineering board examinations.

Following the 2013–2014 Thai political crisis, Prayut attempted to bring the rival parties to an agreement. When that failed, he staged a coup against the caretaker government of Yingluck Shinawatra on 22 May 2014. Yingluck herself had been removed from office earlier by the Constitutional Court, and Niwatthamrong Boonsongpaisan was acting in her place. After the ((coup)), Prayut repealed the 2007 constitution and established the NCPO to govern the nation, with himself as its head. Prayut quickly cracked down on dissent. He put in place controls over the media, imposed Internet censorship, declared a curfew nationwide, which was later lifted within 3 weeks, banned gatherings of five or more persons, and arrested both politicians and anti-coup activists for rhetoric that the authorities considered to go beyond the right of free speech. Some of them were charged with sedition and tried in military courts. The government emphasized that Thailand needed to find a balance between freedom of expression and protecting the interests of the society. It was felt that the right to freedom of expression should not disrupt public order or infringe upon others’ rights.

During the Akkadian Empire (2334–2154 BC), the Assyrians, like all the Akkadian-speaking Mesopotamians (and also the Sumerians), became subject to the dynasty of the city state of Akkad, centered in central Mesopotamia. The Akkadian Empire founded by Sargon the Great claimed to encompass the surrounding "four quarters". The region of Assyria, north of the seat of the empire in central Mesopotamia, had also been known as Subartu by the Sumerians, and the name Azuhinum in Akkadian records also seems to refer to Assyria proper. The Sumerians were eventually absorbed into the Akkadian (Assyro-Babylonian) population.

Bhoja II (910–912) was overthrown by Mahipala I (912–944). Several feudatories of the empire took advantage of the temporary weakness of the Gurjara-Pratiharas to declare their independence, notably the Paramaras of Malwa, the Chandelas of Bundelkhand, the Kalachuris of Mahakoshal, the Tomaras of Haryana, and the Chahamanas of Shakambhari. The south Indian Emperor Indra III (c. 914–928) of the Rashtrakuta dynasty briefly captured Kannauj in 916, and although the Pratiharas regained the city, their position continued to weaken in the 10th century, partly as a result of the drain of simultaneously fighting off Turkic attacks from the west, the attacks from the Rashtrakuta dynasty from the south and the Pala advances in the east. The Gurjara-Pratiharas lost control of Rajasthan to their feudatories, and the Chandelas captured the strategic fortress of Gwalior in central India around 950. By the end of the 10th century the Gurjara-Pratihara domains had dwindled to a small state centered on Kannauj.

Motivation is the reason for people's actions, willingness and goals. Motivation is derived from the word "motive" which is defined as a need that requires satisfaction. These needs could also be wants or desires that are acquired through influence of culture, society, lifestyle, etc. or generally innate. Motivation is one's direction to behavior, or what causes a person to want to repeat a behavior, a set of force that acts behind the motives. An individual's motivation may be inspired by others or events (extrinsic motivation) or it may come from within the individual (intrinsic motivation). Motivation has been considered as one of the most important reasons that inspires a person to move forward. Motivation results from the interaction of both conscious and unconscious factors. Mastering motivation to allow sustained and deliberate practice is central to high levels of achievement e.g. in the worlds of elite sport, medicine or music.

Today's footballs are more complex than past footballs. Most modern footballs consist of twelve regular pentagonal and twenty regular hexagonal panels positioned in a truncated icosahedron spherical geometry. Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality. The inside of the football is made up of a latex bladder which enables the football to be pressurised. The ball's panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine. The size of a football is roughly 22 cm (8.65 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm in circumference. Averaging that to 69 cm and then dividing by gives about 22 cm for a diameter.

Color blindness, also known as color vision deficiency, is the decreased ability to see color or differences in color. Simple tasks such as selecting ripe fruit, choosing clothing, and reading traffic lights can be more challenging. Color blindness may also make some educational activities more difficult. However, problems are generally minor, and most people find that they can adapt. People with total color blindness (achromatopsia) may also have decreased visual acuity and be uncomfortable in bright environments. The most common cause of color blindness is an inherited problem in the development of one or more of the three sets of color sensing cones in the eye. Males are more likely to be color blind than females, as the genes responsible for the most common forms of color blindness are on the X chromosome. As females have two X chromosomes, a defect in one is typically compensated for by the other, while males only have one X chromosome. Color blindness can also result from physical or chemical damage to the eye, optic nerve or parts of the brain. Diagnosis is typically with the Ishihara color test; however, a number of other testing methods also exist. There is no cure for color blindness. Diagnosis may allow a person's teacher to change their method of teaching to accommodate the decreased ability to recognize colors. Special lenses may help people with red-green color blindness when under bright conditions. There are also mobile apps that can help people identify colors. Red-green color blindness is the most common form, followed by blue-yellow color blindness and total color blindness. Red-green color blindness affects up to 8% of males and 0.5% of females of Northern European descent. The ability to see color also decreases in old age. Being color blind may make people ineligible for certain jobs in certain countries. This may include being a pilot, train driver and working in the armed forces. The effect of color blindness on artistic ability, however, is controversial. The ability to draw appears to be unchanged, and a number of famous artists are believed to have been color blind.

Bengalis, consisting of Bengali Hindus, Bengali Muslims, Bengali Christians and a few Bengali Buddhists, comprise the majority of the population. The Marwari, Maithil and Bhojpuri non-Bengali minorities are scattered throughout the state; various indigenous ethnic Buddhist communities such as the Sherpas, Bhutias, Lepchas, Tamangs, Yolmos, and ethnic Tibetans can be found in the Darjeeling Himalayan hill region. Native Magahi speakers are found in Malda district. Surjapuri; a language that is considered to be a mix of Maithili and Bengali, is spoken across northern parts of the state. The Darjeeling district also has a large Nepali immigrant population, making Nepali a widely spoken language in this region. West Bengal is also home to indigenous tribal Adivasis such as Santhal, Munda, Oraon, Bhumij, Lodha, Kol, and Toto tribe. There are a small number of ethnic minorities primarily in the state capital, including Chinese, Tamils, Maharashtrians, Odias, Assamese, Malayalis, Gujaratis, Anglo-Indians, Armenians, Jews, Punjabis, and Parsis. India's sole Chinatown is in eastern Kolkata.

On 25 March 2018, during the third Test match against hosts South Africa; players Cameron Bancroft, Steve Smith, David Warner and the leadership group of the team were implicated in a ball tampering scandal. Smith and Bancroft admitted to conspiring to alter the condition of the ball by rubbing it with a piece of adhesive tape containing abrasive granules picked up from the ground (it was later revealed that sandpaper was used). Smith stated that the purpose was to gain an advantage by unlawfully changing the ball's surface in order to generate reverse swing. Bancroft had been filmed tampering with the ball and after being informed he had been caught, he was seen to transfer a yellow object from a pocket to the inside front of his trousers to hide the evidence. Steve Smith and David Warner were stood down as captain and vice-captain during the third Test while head coach, Darren Lehmann was suspected to have assisted Cameron Bancroft to tamper the ball. The ICC imposed a one-match ban and 100%-match-fee fine on Smith, while Bancroft was fined 75 per cent of his match fee and received 3 demerit points. Smith and Warner were both stripped of their captaincy roles by Cricket Australia and sent home from the tour (along with Bancroft). Tim Paine was appointed as captain for the fourth Test. Cricket Australia then suspended Smith and Warner from playing for 12 months and Bancroft for 9 months. Smith and Bancroft cannot be considered for leadership roles for 12 months after the suspension, while Warner is barred permanently from leadership. In the aftermath of these events, Darren Lehmann announced his resignation as head coach at the end of the series. On 8 May 2018, Tim Paine was also named as ODI captain and Aaron Finch was re-inserted as T20I captain hours later.

Burman was born to the Bollywood composer/singer Sachin Dev Burman and his lyricist wife Meera Dev Burman (née Dasgupta), in Calcutta. Initially, he was nicknamed Tublu by his maternal grandmother, although he later became known by the nickname Pancham. According to some stories, he was nicknamed "Pancham" because, as a child, whenever he cried, it sounded in the fifth note ("Pa"), G scale, of music notation. The word "Pancham" means five (or fifth) in Bengali, his mother tongue. Another theory says that the baby was nicknamed Pancham because he could cry in five different notes. Yet another version is that when the veteran Indian actor Ashok Kumar saw a newborn Rahul uttering the syllable "Pa" repeatedly, he nicknamed the boy "Pancham".

From a classificatory point of view, the Bengali script is an abugida, i.e. its vowel graphemes are mainly realised not as independent letters, but as diacritics modifying the vowel inherent in the base letter they are added to. Bengali script is written from left to right and lacks distinct letter cases. It is recognisable, as are other Brahmic scripts, by a distinctive horizontal line known as "matra" running along the tops of the letters that links them together. The Bengali script is however less blocky and presents a more sinuous shape.


বাংলা সাহিত্যে হাংরি আন্দোলন কবে শুরু হয় ?

The origins of this movement stem from the Chaucer and Spengler. The movement was officially launched however, in November 1961 from the residence of Malay Roy Choudhury and his brother Samir Roychoudhury in Patna. For this reason Malay Roy Choudhury is considered the creator of Hungryalist movement. Malay Roy Choudhury took the word "Hungry" from Geoffrey Chaucer's line "In Sowre Hungry Tyme" and they drew upon, among others, Oswald Spengler's histriographical ideas about the non-centrality of cultural evolution and organic progression, for philosophical inspiration. The movement was to last from 1961 to 1965. It is wrong to suggest that the movement was influenced by the Beat Generation, since Ginsberg did not visit Malay until April 1963, when he came to Patna. Poets Octavio Paz and Ernesto Cardenal were to visit Malay later during the 1960s. The hungry generation has some of the same ideals as The Papelipolas and the Barranquilla Group, both from Colombia, and the Spanish Generation of 68.

The origins of this movement stem from the Chaucer and Spengler. The movement was officially launched however, in November 1961 from the residence of Malay Roy Choudhury and his brother Samir Roychoudhury in Patna. For this reason Malay Roy Choudhury is considered the creator of Hungryalist movement. Malay Roy Choudhury took the word "Hungry" from Geoffrey Chaucer's line "In Sowre Hungry Tyme" and they drew upon, among others, Oswald Spengler's histriographical ideas about the non-centrality of cultural evolution and organic progression, for philosophical inspiration. The movement was to last from 1961 to 1965. It is wrong to suggest that the movement was influenced by the Beat Generation, since Ginsberg did not visit Malay until April 1963, when he came to Patna. Poets Octavio Paz and Ernesto Cardenal were to visit Malay later during the 1960s. The hungry generation has some of the same ideals as The Papelipolas and the Barranquilla Group, both from Colombia, and the Spanish Generation of 68.

Steam locomotives were first developed in Great Britain during the early 19th century and used for railway transport until the middle of the 20th century. The first steam locomotive, made by Richard Trevithick, first operated on 21 February 1804, three years after the road locomotive he made in 1801. The first commercially successful steam locomotive was created in 1812–13 by John Blenkinsop. Built by George Stephenson and his son Robert's company Robert Stephenson and Company, the "Locomotion" No. 1 is the first steam locomotive to carry passengers on a public rail line, the Stockton and Darlington Railway in 1825. George also built the first public inter-city railway line in the world to use locomotives, the Liverpool and Manchester Railway, which opened in 1830. Stephenson established his company as the pre-eminent builder of steam locomotives for railways in the United Kingdom, the United States, and much of Europe.

The troposphere is the lowest layer of Earth's atmosphere. It extends from Earth's surface to an average height of about , although this altitude varies from about at the geographic poles to at the Equator, with some variation due to weather. The troposphere is bounded above by the tropopause, a boundary marked in most places by a temperature inversion (i.e. a layer of relatively warm air above a colder one), and in others by a zone which is isothermal with height.

Avram Noam Chomsky (born December 7, 1928) is an American linguist, philosopher, cognitive scientist, historian, political activist, and social critic. Sometimes called "the father of modern linguistics", Chomsky is also a major figure in analytic philosophy and one of the founders of the field of cognitive science. He holds a joint appointment as Institute Professor Emeritus at the Massachusetts Institute of Technology (MIT) and laureate professor at the University of Arizona, and is the author of over 100 books on topics such as linguistics, war, politics, and mass media. Ideologically, he aligns with anarcho-syndicalism and libertarian socialism. Born to middle-class Ashkenazi Jewish immigrants in Philadelphia, Chomsky developed an early interest in anarchism from alternative bookstores in New York City. He began studying at the University of Pennsylvania at age 16, taking courses in linguistics, mathematics, and philosophy. From 1951 to 1955, he was appointed to Harvard University's Society of Fellows. While at Harvard, he developed the theory of transformational grammar; for this, he was awarded his doctorate in 1955. Chomsky began teaching at MIT in 1957 and emerged as a significant figure in the field of linguistics for his landmark work "Syntactic Structures", which remodelled the scientific study of language. From 1958 to 1959, he was a National Science Foundation fellow at the Institute for Advanced Study. Chomsky is credited as the creator or co-creator of the universal grammar theory, the generative grammar theory, the Chomsky hierarchy, and the minimalist program. He also played a pivotal role in the decline of behaviorism, being particularly critical of the work of B. F. Skinner. Chomsky vocally opposed U.S. involvement in the Vietnam War, believing the war to be an act of American imperialism. In 1967, he attracted widespread public attention for his antiwar essay "The Responsibility of Intellectuals". Associated with the New Left, he was arrested multiple times for his activism and was placed on Richard Nixon's Enemies List. While expanding his work in linguistics over subsequent decades, he also became involved in the Linguistics Wars. In collaboration with Edward S. Herman, Chomsky later co-wrote "", which articulated the propaganda model of media criticism and worked to expose the Indonesian occupation of East Timor. Additionally, his defense of freedom of speech—including free speech for Holocaust deniers—generated significant controversy in the Faurisson affair of the early 1980s. Since retiring from active teaching, Chomsky has continued his vocal political activism by opposing the War on Terror and supporting the Occupy Movement. One of the most cited scholars in history, Chomsky has influenced a broad array of academic fields. He is widely recognized as a paradigm shifter who helped spark a major revolution in the human sciences, contributing to the development of a new cognitivistic framework for the study of language and the mind. In addition to his continued scholarly research, he remains a leading critic of U.S. foreign policy, neoliberalism and contemporary state capitalism, the Israeli–Palestinian conflict, and mainstream news media. His ideas have proved highly significant within the anti-capitalist and anti-imperialist movements. Some of his critics have accused him of anti-Americanism.

The word "television" comes . The first documented usage of the term dates back to 1900, when the Russian scientist Constantin Perskyi used it in a paper that he presented in French at the 1st International Congress of Electricity, which ran from 18 to 25 August 1900 during the International World Fair in Paris. The Anglicised version of the term is first attested in 1907, when it was still "...a theoretical system to transmit moving images over telegraph or telephone wires". It was "...formed in English or borrowed from French télévision." In the 19th century and early 20th century, other "...proposals for the name of a then-hypothetical technology for sending pictures over distance were telephote (1880) and televista (1904)." The abbreviation "TV" is from 1948. The use of the term to mean "a television set" dates from 1941. The use of the term to mean "television as a medium" dates from 1927. The slang term "telly" is more common in the UK. The slang term "the tube" or the "boob tube" derives from the bulky cathode ray tube used on most TVs until the advent of flat-screen TVs. Another slang term for the TV is "idiot box". Also, in the 1940s and throughout the 1950s, during the early rapid growth of television programming and television-set ownership in the United States, another slang term became widely used in that period and continues to be used today to distinguish productions originally created for broadcast on television from films developed for presentation in movie theaters. The “small screen”, as both a compound adjective and noun, became specific references to television, while the “big screen” was used to identify productions made for theatrical release.

Charles Robert Darwin, (; 12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.

The history of evolutionary psychology began with Charles Darwin, who said that humans have social instincts that evolved by natural selection. Darwin's work inspired later psychologists such as William James and Sigmund Freud but for most of the 20th century psychologists focused more on behaviorism and proximate explanations for human behavior. E. O. Wilson's landmark 1975 book, "", synthesized recent theoretical advances in evolutionary theory to explain social behavior in animals, including humans. Jerome Barkow, Leda Cosmides and John Tooby popularized the term "evolutionary psychology" in their 1992 book "The Adapted Mind: Evolutionary Psychology and The Generation of Culture". Like sociobiology before it, evolutionary psychology has been embroiled in controversy, but evolutionary psychologists see their field as gaining increased acceptance overall.

বিবাহ শব্দটির উৎপত্তি কোন শব্দ থেকে ?

The word "marriage" derives from Middle English "mariage", which first appears in 1250–1300 CE. This in turn is derived from Old French, "marier" (to marry), and ultimately Latin, "marītāre", meaning to provide with a husband or wife and "marītāri" meaning to get married. The adjective "marīt-us -a, -um" meaning matrimonial or nuptial could also be used in the masculine form as a noun for "husband" and in the feminine form for "wife". The related word "matrimony" derives from the Old French word "matremoine", which appears around 1300 CE and ultimately derives from Latin "mātrimōnium", which combines the two concepts: "mater" meaning "mother" and the suffix -"monium" signifying "action, state, or condition".

The term "globalization" derives from the word "globalize", which refers to the emergence of an international network of economic systems. One of the earliest known usages of the term as a noun was in a 1930 publication entitled "Towards New Education", where it denoted a holistic view of human experience in education. The term 'globalization' had been used in its economic sense at least as early as 1981, and in other senses since at least as early as 1944. Theodore Levitt is credited with popularizing the term and bringing it into the mainstream business audience in the later half of the 1980s. Since its inception, the concept of globalization has inspired competing definitions and interpretations. Its antecedents date back to the great movements of trade and empire across Asia and the Indian Ocean from the 15th century onward. Due to the complexity of the concept, various research projects, articles, and discussions often stay focused on a single aspect of globalization.

According to the United Nations Office on Drugs and Crime, Pakistan has 6.7 million drug users. More than 4 million of these are addicts, amongst the highest number for any country in the world. Abuse of cannabis and heroin is rife in the country and the drugs are extremely cheap and easy to get. Most of the drugs come from Afghanistan, the country that is responsible for at least 75% of the world's heroin. UNODC calculates that more than 800,000 Pakistanis aged between 15 and 64 use heroin regularly. It is also estimated that up to 44 tons of processed heroin are consumed annually in Pakistan - a rate of use twice or thrice that of America's. A further 110 tons of heroin and morphine from neighboring Afghanistan are trafficked through Pakistan to international markets. Furthermore, Pakistan’s illegal drug trade is believed to generate up to $2 billion a year.

As Thomas Hall (2000) notes, "The Sung Empire in particular nearly underwent a transformation to capitalism in the tenth century C.E. But the only states to be controlled by capitalists before the European transformation in the seventeenth century were semiperipheral capitalist city-states such as the Phoenician cities, Venice, Genoa, and Malacca. These operated in the interstices between the tributary states and empires, and though they were agents of commodification, they existed within larger systems in which the logic of state-based coercion remained dominant. The first capitalist nation-state was the Dutch Republic in the seventeenth century. This coming to state power by capitalists in an emerging core region signaled the triumph of regional capitalism in the European subsystem." In Werner Sombart's words, "In all probability the United Provinces were the land in which the capitalist spirit for the first time attained its fullest maturity; where this maturity related to all its aspects, which were equally developed; and where this development had never been done comprehensive before. Moreover, in the Netherlands an entire people became imbued with the capitalist spirit; so much so, that in the 17th century Holland was universally regarded as the land of capitalism par exellence; it was envied by all other nations, who put forth their keenest endeavours in their desire to emulate it; it was the high school of every art of the tradesman, and the well-watered garden wherein the middle-class virtues throve." Foundational thinkers for this approach include Adam Smith, Max Weber, Fernand Braudel, Henri Pirenne, and Paul Sweezy.

In eastern Congo, the prevalence and intensity of rape and other sexual violence is described as the worst in the world. It is estimated that there are as many as 200,000 surviving rape victims living in the Democratic Republic of the Congo today. A new study says more than 400,000 women are raped in the Democratic Republic of Congo annually. War rape in the Democratic Republic of Congo has frequently been described as a "weapon of war" by commentators. Louise Nzigire, a local social worker, states that "this violence was designed to exterminate the population." Nzigire observes that rape has been a "cheap, simple weapon for all parties in the war, more easily obtainable than bullets or bombs." In an analysis of 2565 patients who received medical care in the Médecins Sans Frontières sexual violence clinic in the capital of Ituri, Bunia, between 2005 and 2006, 73% (95.2% of male victims) reported being raped by armed men. 74.5% experienced gang rape (89.3% of male and 73.9% of female victims), with attack by between 2 and 4 perpetrators being the most common scenario (58.9%) for both sexes. 48.6% of victims were attacked while doing daily domestic activities outside their homes.

The development of microprocessors made inexpensive computing available for the small business and hobbyist, which in turn led to the widespread use of interchangeable hardware components using a common interconnection (such as the S-100, SS-50, Apple II, ISA, and PCI buses), and an increasing need for "standard" operating systems to control them. The most important of the early OSes on these machines was Digital Research's CP/M-80 for the 8080 / 8085 / Z-80 CPUs. It was based on several Digital Equipment Corporation operating systems, mostly for the PDP-11 architecture. Microsoft's first operating system, MDOS/MIDAS, was designed along many of the PDP-11 features, but for microprocessor based systems. MS-DOS, or PC DOS when supplied by IBM, was based originally on CP/M-80. Each of these machines had a small boot program in ROM which loaded the OS itself from disk. The BIOS on the IBM-PC class machines was an extension of this idea and has accreted more features and functions in the 20 years since the first IBM-PC was introduced in 1981.

The first partially successful photograph of a camera image was made in approximately 1816 by Nicéphore Niépce, using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light. No means of removing the remaining unaffected silver chloride was known to Niépce, so the photograph was not permanent, eventually becoming entirely darkened by the overall exposure to light necessary for viewing it. In the mid-1820s, Niépce used a sliding wooden box camera made by Parisian opticians Charles and Vincent Chevalier to experiment with photography on surfaces thinly coated with Bitumen of Judea. The bitumen slowly hardened in the brightest areas of the image. The unhardened bitumen was then dissolved away. One of those photographs has survived.

Silicon Graphics, Inc (SGI) was a manufacturer of high-performance computer hardware and software, founded in 1981 by Jim Clark. His idea, called the Geometry Engine, was to create a series of components in a VLSI processor that would accomplish the main operations required in image synthesis—the matrix transforms, clipping, and the scaling operations that provided the transformation to view space. Clark attempted to shop his design around to computer companies, and finding no takers, he and colleagues at Stanford University, California, started their own company, Silicon Graphics.

Johannes Gutenberg, a goldsmith by profession, developed, circa 1439, a printing system by adapting existing technologies to printing purposes, as well as making inventions of his own. Printing in East Asia had been prevalent since the Tang dynasty, and in Europe, woodblock printing based on existing screw presses was common by the 14th century. Gutenberg's most important innovation was the development of hand-molded metal printing matrices, thus producing a movable type-based printing press system. His newly devised hand mould made possible the precise and rapid creation of metal movable type in large quantities. Movable type had been hitherto unknown in Europe. In Europe, the two inventions, the hand mould and the printing press, together drastically reduced the cost of printing books and other documents, particularly in short print runs.

In 1886, Albert Ballin joined HAPAG () as manager of its passage department. Thirteen years later, in 1899, he became managing director. It was during this term that he realized his company’s largest and flagship vessel, , lay largely unused during the winter season. Due to inclement weather, travelers largely stayed away from the North Atlantic route. It was then that Ballin, despite criticism from his fellow directors at HAPAG and other steamship companies, planned to send "Augusta Victoria" on a 58-day “pleasure voyage” from Cuxhaven, Germany to the Mediterranean and Orient. This extended cruise would include well-planned excursions ashore to ports-of-call along the route and Ballin would be a passenger himself. The voyage was a success, and similar ones were planned.
