Indianapolis Motor Speedway
–
The Indianapolis Motor Speedway is an automobile racing circuit located in Speedway, Indiana, in the United States. It is the home of the Indianapolis 500 and the Brickyard 400 and it is located on the corner of 16th Street and Georgetown Road, approximately six miles west of Downtown Indianapolis. Constructed in 1909, it is the original speedway, the first racing facility so named and it has a permanent seating capacity estimated at 235,000 with infield seating raising capacity to an approximate 400,000. It is the highest-capacity sports venue in the world, considered relatively flat by American standards, the track is a 2. 5-mile-long rectangular oval with dimensions that have remained essentially unchanged since its construction. A modern infield road course was completed in 2000, incorporating part of the oval, including the mainstretch, in 2008, and again in 2014, the road course layout was modified to accommodate motorcycle racing, as well as to improve competition. Altogether, the current grounds have expanded from an original 320 acres on which the speedway was first built to cover an area of over 559 acres. Placed on the National Register of Historic Places in 1975 and designated a National Historic Landmark in 1987, in addition to the Indianapolis 500, the speedway also hosts NASCARs Brickyard 400 and Lilly Diabetes 250. From 2000 to 2007, the hosted the Formula One United States Grand Prix. On the grounds of the speedway is the Indianapolis Motor Speedway Museum, which opened in 1956, the museum moved into its current building located in the infield in 1976. Also on the grounds is the Brickyard Crossing Golf Resort, which opened as the Speedway Golf Course in 1929. The golf course has 14 holes outside of the track, along the backstretch, the speedway also served as the venue for the opening ceremonies for the 1987 Pan American Games. Fisher began thinking of a means of testing cars before delivering them to consumers. At the time, racing was just getting started on horse tracks, Fisher noticed how dangerous and ill-suited the makeshift courses were for racing and testing. He also argued that spectators did not get their moneys worth, Fisher proposed building a circular track 3 to 5 miles long with smooth 100–150-foot-wide surfaces. Such a track would give manufacturers a chance to test cars at sustained speeds, Fisher predicted speeds could reach up to 120 mph on a 5-mile course. He visited the Brooklands circuit outside London in 1907, and after viewing the banked layout, in December 1908, he convinced James A. Allison, Arthur Newby, and Frank W. Wheeler to join him in purchasing the property for $72,000. Construction of the started in March 1909. Fisher had to downsize his planned 3-mile oval with a 2-mile road course to a 2. 5-mile oval to leave room for the grandstands

Law
–
Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. Law as a system helps regulate and ensure that a community show respect, private individuals can create legally binding contracts, including arbitration agreements that may elect to accept alternative arbitration to the normal court process. The formation of laws themselves may be influenced by a constitution, written or tacit, the law shapes politics, economics, history and society in various ways and serves as a mediator of relations between people. Islamic Sharia law is the worlds most widely used religious law, the adjudication of the law is generally divided into two main areas referred to as Criminal law and Civil law. Criminal law deals with conduct that is considered harmful to social order, Civil law deals with the resolution of lawsuits between individuals or organizations. Law provides a source of scholarly inquiry into legal history, philosophy, economic analysis. Law also raises important and complex issues concerning equality, fairness, there is an old saying that all are equal before the law, although Jonathan Swift argued that Laws are like cobwebs, which may catch small flies, but let wasps and hornets break through. In 1894, the author Anatole France said sarcastically, In its majestic equality, the law forbids rich and poor alike to sleep under bridges, beg in the streets, and steal loaves of bread. Writing in 350 BC, the Greek philosopher Aristotle declared, The rule of law is better than the rule of any individual, mikhail Bakunin said, All law has for its object to confirm and exalt into a system the exploitation of the workers by a ruling class. Cicero said more law, less justice, marxist doctrine asserts that law will not be required once the state has withered away. Regardless of ones view of the law, it today a completely central institution. Numerous definitions of law have been put forward over the centuries, at the same time, it plays only one part in the congeries of rules which influence behavior, for social and moral rules of a less institutionalized kind are also of great importance. There have been attempts to produce a universally acceptable definition of law. In 1972, one indicated that no such definition could be produced. McCoubrey and White said that the question what is law, glanville Williams said that the meaning of the word law depends on the context in which that word is used. He said that, for example, early customary law and municipal law were contexts where the law had two different and irreconcilable meanings. Thurman Arnold said that it is obvious that it is impossible to define the word law and it is possible to take the view that there is no need to define the word law. The history of law links closely to the development of civilization, Ancient Egyptian law, dating as far back as 3000 BC, contained a civil code that was probably broken into twelve books

Car
–
A car is a wheeled, self-powered motor vehicle used for transportation and a product of the automotive industry. The year 1886 is regarded as the year of the modern car. In that year, German inventor Karl Benz built the Benz Patent-Motorwagen, cars did not become widely available until the early 20th century. One of the first cars that was accessible to the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the United States of America, where they replaced animal-drawn carriages and carts, cars are equipped with controls used for driving, parking, passenger comfort and safety, and controlling a variety of lights. Over the decades, additional features and controls have been added to vehicles, examples include rear reversing cameras, air conditioning, navigation systems, and in car entertainment. Most cars in use in the 2010s are propelled by a combustion engine. Both fuels cause air pollution and are blamed for contributing to climate change. Vehicles using alternative fuels such as ethanol flexible-fuel vehicles and natural gas vehicles are also gaining popularity in some countries, electric cars, which were invented early in the history of the car, began to become commercially available in 2008. There are costs and benefits to car use, the costs of car usage include the cost of, acquiring the vehicle, interest payments, repairs and auto maintenance, fuel, depreciation, driving time, parking fees, taxes, and insurance. The costs to society of car use include, maintaining roads, land use, road congestion, air pollution, public health, health care, road traffic accidents are the largest cause of injury-related deaths worldwide. The benefits may include transportation, mobility, independence. The ability for humans to move flexibly from place to place has far-reaching implications for the nature of societies and it was estimated in 2010 that the number of cars had risen to over 1 billion vehicles, up from the 500 million of 1986. The numbers are increasing rapidly, especially in China, India, the word car is believed to originate from the Latin word carrus or carrum, or the Middle English word carre. In turn, these originated from the Gaulish word karros, the Gaulish language was a branch of the Brythoic language which also used the word Karr, the Brythonig language evolved into Welsh where Car llusg and car rhyfel still survive. It originally referred to any wheeled vehicle, such as a cart, carriage. Motor car is attested from 1895, and is the formal name for cars in British English. Autocar is a variant that is attested from 1895

Stadium
–
Pausanias noted that for about half a century the only event at the ancient Greek Olympic festival was the race that comprised one length of the stade at Olympia, where the word stadium originated. In modern times, a stadium is officially a stadium when at least 50% of the capacity is an actual building. If the majority of the capacity is formed by grasshills, the venue is not officially considered a stadium. Most of the stadiums with a capacity of at least 10,000 are used for football, or soccer. A large amount of sports venues are also used for concerts. Stadium is the Latin form of the Greek word stadion, a measure of length equalling the length of 600 human feet, as feet are of variable length the exact length of a stadion depends on the exact length adopted for 1 foot at a given place and time. Although in modern terms 1 stadion =600 ft, in a historical context it may actually signify a length up to 15% larger or smaller. The equivalent Roman measure, the stadium, had a similar length — about 185 m -, the English use of stadium comes from the tiered infrastructure surrounding a Roman track of such length. Most dictionaries provide for both stadiums and stadia as valid English plurals, although etymological purists sometimes apply stadia only to measures of length in excess of 1 stadium. The oldest known stadium is the one in Olympia, in the western Peloponnese, Greece, initially the Games consisted of a single event, a sprint along the length of the stadium. The stadion, a measure of length, may be related to the Stadium, Greek and Roman stadiums have been found in numerous ancient cities, perhaps the most famous being the Stadium of Domitian, in Rome. The excavated and refurbished ancient Panathenaic stadium hosted a version of the Olympic Games in 1870,1875,1896 and 1906. The excavation and refurbishment of the stadium was part of the legacy of the Greek national benefactor Evangelos Zappas, the first stadiums to be built in the modern era were basic facilities, designed for the single purpose of fitting as many spectators in as possible. One such early stadium was the Lansdowne Road Stadium, the brainchild of Henry Dunlop, banned from locating sporting events at Trinity College, Dunlop built the stadium in 1872. Some 300 cartloads of soil from a trench beneath the railway were used to raise the ground, other early stadiums from this period in the UK include the Stamford Bridge stadium and Anfield stadium. In the U. S. However, many of these caught fire. All of the 19th-century wooden parks were replaced, some only a few years. Goodison Park was the first purpose-built football stadium in the world, walton-based building firm Kelly brothers were instructed to erect two uncovered stands that could each accommodate 4,000 spectators

Melbourne Cricket Ground
–
The Melbourne Cricket Ground, also known simply as The G, is an Australian sports stadium located in Yarra Park, Melbourne, Victoria. The MCG is within walking distance of the city centre and is served by the Richmond railway station, Richmond, and it is part of the Melbourne Sports and Entertainment Precinct. Since it was built in 1853, the MCG has been in a state of almost constant renewal and it served as the centrepiece stadium of the 1956 Summer Olympics, the 2006 Commonwealth Games and two Cricket World Cups,1992 and 2015. The annual Boxing Day Test is one of the MCGs most popular events, the stadium fills to capacity for the AFL Grand Final. Concerts and other events are also held at the venue. The MCG is listed on the Victorian Heritage Register and was included on the Australian National Heritage List in 2005, journalist Greg Baum called it a shrine, a citadel, a landmark, a totem that symbolises Melbourne to the world. Founded in November 1838 the Melbourne Cricket Club selected the current MCG site in 1853 after previously playing at several grounds around Melbourne, the club’s first game was against a military team at the Old Mint site, at the corner of William and Latrobe Streets. The area was subject to flooding, forcing the club to move again and it was not long before the club was forced out again, this time because of the expansion of the railway. The South Melbourne ground was in the path of Victoria’s first steam railway line from Melbourne to Sandridge and this last option, which is now Yarra Park, had been used by Aborigines until 1835. Between 1835 and 1853 it was an agistment area for colonial troopers’ horses, in 1850 it was part of a 200-acre stretch set aside for public recreation extending from Governor La Trobe’s Jolimont Estate to the Yarra River. By 1853 it had become a busy promenade for Melbourne residents, an MCC sub-committee chose the Richmond Park option because it was level enough for cricket but sloped enough to prevent inundation. That ground was located where the Richmond, or outer, end of the current MCG is now, at the same time the Richmond Cricket Club was given occupancy rights to six acres for another cricket ground on the eastern side of the Government Paddock. At the time of the grant the Government stipulated that the ground was to be used for cricket and cricket only. This condition remained until 1933 when the State Government allowed the MCG’s uses to be broadened to other purposes when not being used for cricket. In 1863 a corridor of land running diagonally across Yarra Park was granted to the Hobson’s Bay Railway, the area closest to the river was also developed for sporting purposes in later years including Olympic venues in 1956. The first grandstand at the MCG was the original wooden stand built in 1854. It was during this tour that the MCG hosted the worlds first Test match, in 1881 the original members stand was sold to the Richmond Cricket Club for £55. A new brick stand, considered at the time to be the world’s finest cricket facility, was built in its place, the foundation stone was laid by Prince George of Wales and Prince Albert Victor on 4 July and the stand opened in December that year

Cricket World Cup
–
The ICC Cricket World Cup is the international championship of One Day International cricket. The event is organised by the governing body, the International Cricket Council, every four years. The tournament is one of the worlds most viewed sporting events and is considered the event of the international cricket calendar by the ICC. The first World Cup was organised in England in June 1975, the first three World Cups were held in England. From the 1987 tournament onwards, hosting has been shared between countries under a rotation system, with fourteen ICC members having hosted at least one match in the tournament. A total of twenty teams have competed in the editions of the tournament. Australia has won the tournament five times, with the West Indies, India, Pakistan, the best performance by a non-full-member team came when Kenya made the semi-finals of the 2003 tournament. The first international match was played between Canada and the United States, on 24 and 25 September 1844. However, the first credited Test match was played in 1877 between Australia and England, and the two teams competed regularly for The Ashes in subsequent years, South Africa was admitted to Test status in 1889. Representative cricket teams were selected to each other, resulting in bilateral competition. Cricket was also included as an Olympic sport at the 1900 Paris Games and this was the only appearance of cricket at the Summer Olympics. The event was not a success, the summer was exceptionally wet, making play difficult on damp uncovered pitches, since then, international Test cricket has generally been organised as bilateral series, a multilateral Test tournament was not organised again until the triangular Asian Test Championship in 1999. The number of nations playing Test cricket increased gradually over time, with the addition of West Indies in 1928, New Zealand in 1930, India in 1932, however, international cricket continued to be played as bilateral Test matches over three, four or five days. In the early 1960s, English county cricket teams playing a shortened version of cricket which only lasted for one day. Starting in 1962 with a knockout competition known as the Midlands Knock-Out Cup. A national Sunday League was formed in 1969 and it was a forty over game with eight balls per over. In the late 1970s, Kerry Packer established the rival World Series Cricket competition, the first of the matches with coloured uniforms was the WSC Australians in wattle gold versus WSC West Indians in coral pink, played at VFL Park in Melbourne on 17 January 1979. The inaugural Cricket World Cup was hosted in 1975 by England, the 1975 tournament started on 7 June

Wheelchair
–
A wheelchair, often abbreviated to just chair, is a chair with wheels, used when walking is difficult or impossible due to illness, injury, or disability. Wheelchairs come in a variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The earliest records of wheeled furniture are an inscription found on a slate in China. The first records of wheeled seats being used for transporting disabled people date to three centuries later in China, the Chinese used early wheelbarrows to move people as well as heavy objects. A distinction between the two functions was not made for several hundred years, around 525 CE, when images of wheeled chairs made specifically to carry people begin to occur in Chinese art. Later records show the use of technology in Europe by the Renaissance. The invalid carriage or Bath chair brought the technology into more common use from around 1760, in 1887, wheelchairs were introduced to Atlantic City so invalid tourists could rent them to enjoy the Boardwalk. Soon, many healthy tourists also rented the decorated rolling chairs and servants to them as a show of decadence. In 1933 Harry Jennings and his disabled friend Herbert Everest, both engineers, invented the first lightweight, steel, collapsible wheelchair. Everest had previously broken his back in a mining accident, Everest and Jennings saw the business potential of the invention and went on to become the first mass-market manufacturers of wheelchairs. Their x-brace design is still in use, albeit with updated materials. There are a variety of types of wheelchair, differing by propulsion method, mechanisms of control. Some wheelchairs are designed for everyday use, others for single activities. The iBot is perhaps the best known example of this in recent years, a self-propelled manual wheelchair incorporates a frame, seat, one or two footplates and four wheels, usually two caster wheels at the front and two large wheels at the back. There will generally also be a seat cushion. As this causes friction and heat build-up, particularly on long downslopes, everyday manual wheelchairs come in two major varieties, folding or rigid. Folding chairs are generally low-end designs, whose predominant advantage is being able to fold, however this is largely an advantage for part-time users who may need to store the wheelchair more often than use it

Ballroom
–
A ballroom or ballhall is a large room inside a building, the designated purpose of which is holding large formal parties called balls. Traditionally, most balls were held in private residences, many mansions contain one or more ballrooms, ballrooms are generally quite large, and may have ceilings higher than other rooms in the same building. The large amount of space for dancing, as well as the formal tone of events have given rise to ballroom dancing. The largest balls are now nearly always held in public buildings and they are also designed large to help the sound of orchestras carry well throughout the whole room. A special case is the annual Vienna Opera Ball, where, just for one night, on the eve of the event, the rows of seats are removed from the stalls, and a new floor, level with the stage, is built. Sometimes ballrooms have stages in the front of the room where the host or a special guest can speak and that stage can also be used for instrumentalists and musical performers. These lists should only include ballrooms with permanent wood floors, the size of the floor should only include the largest contiguous area without obstructions. The web sites and materials about some places add up multiple spaces, rooms, and balconies, however, this list ranks ballrooms based on the size of one single open space with a hardwood floor.

Arena
–
An arena is an enclosed area, often circular or oval-shaped, designed to showcase theater, musical performances, or sporting events. The word derives from Latin harena, a particularly fine/smooth sand used to absorb blood in ancient arenas such as the Colosseum in Rome and it is composed of a large open space surrounded on most or all sides by tiered seating for spectators. The key feature of an arena is that the event space is the lowest point, arenas are usually designed to accommodate a large number of spectators. The term arena is used as a synonym for a very large venue such as Pasadenas Rose Bowl. The use of one term over the other has mostly to do with the type of event, the home of the Duke University mens and womens basketball teams would qualify as an arena, but the facility is called Cameron Indoor Stadium. Domed stadiums, which, like arenas, are enclosed but have the larger playing surfaces, such examples of these would be terms such as the arena of war or the arena of love or the political arena. In many fighting games, the stage that opponents are fought in is called an arena. Ice hockey arena Amphitheatre List of indoor arenas by capacity List of stadiums by capacity

National Football League
–
The National Football League is a professional American football league consisting of 32 teams, divided equally between the National Football Conference and the American Football Conference. The NFL is one of the four professional sports leagues in North America. The NFLs 17-week regular season runs from the week after Labor Day to the week after Christmas, with each team playing 16 games, the NFL was formed in 1920 as the American Professional Football Association before renaming itself the National Football League for the 1922 season. The NFL agreed to merge with the American Football League in 1966, and the first Super Bowl was held at the end of that season, the merger was completed in 1970. Today, the NFL has the highest average attendance of any sports league in the world and is the most popular sports league in the United States. S. The NFLs executive officer is the commissioner, who has authority in governing the league. The team with the most NFL championships is the Green Bay Packers with thirteen, the current NFL champions are the New England Patriots, who defeated the Atlanta Falcons 34–28 in Super Bowl LI. Another meeting held on September 17,1920 resulted in the renaming of the league to the American Professional Football Association, the league hired Jim Thorpe as its first president, and consisted of 14 teams. Only two of these teams, the Decatur Staleys and the Chicago Cardinals, remain, the first event occurred on September 26,1920 when the Rock Island Independents defeated the non-league St. Paul Ideals 48–0 at Douglas Park. On October 3,1920, the first full week of league play occurred, the following season resulted in the Chicago Staleys controversially winning the title over the Buffalo All-Americans. In 1922, the APFA changed its name to the National Football League, in 1932, the season ended with the Chicago Bears and the Portsmouth Spartans tied for first in the league standings. This method had used since the leagues creation in 1920. The league quickly determined that a game between Chicago and Portsmouth was needed to decide the leagues champion. Playing with altered rules to accommodate the playing field, the Bears won the game 9–0. Fan interest in the de facto championship game led the NFL, beginning in 1933, the 1934 season also marked the first of 12 seasons in which African Americans were absent from the league. The de facto ban was rescinded in 1946, following public pressure, the NFL was always the foremost professional football league in the United States, it nevertheless faced a large number of rival professional leagues through the 1930s and 1940s. Rival leagues included at least three separate American Football Leagues and the All-America Football Conference, on top of regional leagues of varying caliber. Three NFL teams trace their histories to these leagues, including the Los Angeles Rams
11.
Super Bowl
–
The Super Bowl is the annual championship game of the National Football League. The game is the culmination to a season that begins in the late summer of the previous calendar year. Normally, Roman numerals are used to each game, rather than the year in which it is held. For example, Super Bowl I was played on January 15,1967, the single exception to this rule is Super Bowl 50, which was played on February 7,2016, following the 2015 regular season. The next game, Super Bowl LII, scheduled for February 4,2018, the game was created as part of a merger agreement between the NFL and its then-rival league, the American Football League. It was agreed that the two champion teams would play in the AFL–NFL World Championship Game until the merger was to officially begin in 1970. After the merger, each league was redesignated as a conference, currently, the National Football Conference leads the league with 26 wins to 25 wins for the American Football Conference. The Pittsburgh Steelers have the most Super Bowl championship titles, with six, the New England Patriots have the most Super Bowl appearances, with nine. The day on which the Super Bowl is played, now considered by some as an unofficial American national holiday, is called Super Bowl Sunday and it is the second-largest day for U. S. food consumption, after Thanksgiving Day. In addition, the Super Bowl has frequently been the most-watched American television broadcast of the year, in 2015, Super Bowl XLIX became the most-watched American television program in history with an average audience of 114. The NFL restricts the use of its Super Bowl trademark, it is called the Big Game or other generic terms by non-sponsoring corporations. As a result, watching and discussing the broadcasts commercials has become a significant aspect of the event, for four decades after its 1920 inception, the NFL successfully fended off several rival leagues. However, in 1960, it encountered its most serious competitor when the American Football League was formed. The AFL vied heavily with the NFL for both players and fans, but by the middle of the decade the strain of competition led to merger talks between the two leagues. Prior to the 1966 season, the NFL and AFL reached an agreement that was to take effect for the 1970 season. As part of the merger, the champions of the two agreed to meet in a world championship game for professional American football until the merger was effected. A bowl game is a college football game. Exploiting the Rose Bowl Games popularity, post-season college football contests were created for Miami, New Orleans, and El Paso, Texas in 1935, by the time the first Super Bowl was played, the term bowl for any major American football game was well established

Number
–
Numbers that answer the question How many. Are 0,1,2,3 and so on, when used to indicate position in a sequence they are ordinal numbers. To the Pythagoreans and Greek mathematician Euclid, the numbers were 2,3,4,5, Euclid did not consider 1 to be a number. Numbers like 3 +17 =227, expressible as fractions in which the numerator and denominator are whole numbers, are rational numbers and these make it possible to measure such quantities as two and a quarter gallons and six and a half miles. What we today would consider a proof that a number is irrational Euclid called a proof that two lengths arising in geometry have no common measure, or are incommensurable, Euclid included proofs of incommensurability of lengths arising in geometry in his Elements. In the Rhind Mathematical Papyrus, a pair of walking forward marked addition. They were the first known civilization to use negative numbers, negative numbers came into widespread use as a result of their utility in accounting. They were used by late medieval Italian bankers, by 1740 BC, the Egyptians had a symbol for zero in accounting texts. In Maya civilization zero was a numeral with a shape as a symbol. The ancient Egyptians represented all fractions in terms of sums of fractions with numerator 1, for example, 2/5 = 1/3 + 1/15. Such representations are known as Egyptian Fractions or Unit Fractions. The earliest written approximations of π are found in Egypt and Babylon, in Babylon, a clay tablet dated 1900–1600 BC has a geometrical statement that, by implication, treats π as 25/8 =3.1250. In Egypt, the Rhind Papyrus, dated around 1650 BC, astronomical calculations in the Shatapatha Brahmana use a fractional approximation of 339/108 ≈3.139. Other Indian sources by about 150 BC treat π as √10 ≈3.1622 The first references to the constant e were published in 1618 in the table of an appendix of a work on logarithms by John Napier. However, this did not contain the constant itself, but simply a list of logarithms calculated from the constant and it is assumed that the table was written by William Oughtred. The discovery of the constant itself is credited to Jacob Bernoulli, the first known use of the constant, represented by the letter b, was in correspondence from Gottfried Leibniz to Christiaan Huygens in 1690 and 1691. Leonhard Euler introduced the letter e as the base for natural logarithms, Euler started to use the letter e for the constant in 1727 or 1728, in an unpublished paper on explosive forces in cannons, and the first appearance of e in a publication was Eulers Mechanica. While in the subsequent years some researchers used the letter c, e was more common, the first numeral system known is Babylonian numeric system, that has a 60 base, it was introduced in 3100 B. C. and is the first Positional numeral system known

Vehicle
–
A vehicle is a mobile machine that transports people or cargo. Typical vehicles include wagons, bicycles, motor vehicles, railed vehicles, Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground, wheeled, tracked, railed or skied. ISO 3833-1977 is the standard, also used in legislation, for road vehicles types, terms. Boats were used between 4000 BC-3000 BC in Sumer, ancient Egypt and in the Indian Ocean, there is evidence of camel pulled wheeled vehicles about 3000–4000 BC. Wheeled vehicles pulled by men and animals ran in grooves in limestone, in 200 CE, Ma Jun built a south-pointing chariot, a vehicle with an early form of guidance system. Railways began reappearing in Europe after the Dark Ages, the earliest known record of a railway in Europe from this period is a stained-glass window in the Minster of Freiburg im Breisgau dating from around 1350. In 1515, Cardinal Matthäus Lang wrote a description of the Reisszug, the line originally used wooden rails and a hemp haulage rope and was operated by human or animal power, through a treadwheel. 1769 Nicolas-Joseph Cugnot is often credited with building the first self-propelled mechanical vehicle or automobile in 1769. In Russia, in the 1780s, Ivan Kulibin developed a human-pedalled, three-wheeled carriage with modern features such as a flywheel, brake, gear box and bearings, however and it was introduced by Drais to the public in Mannheim in summer 1817. 1903 Wright brothers flew the first controlled, powered aircraft 1907 First helicopters Gyroplane no.1, there are over 1 billion bicycles in use worldwide. In 2002 there were an estimated 590 million cars and 205 million motorcycles in service in the world, at least 500 million Chinese Flying Pigeon bicycles have been made, more than an other single model of vehicle. The most-produced model of vehicle is the Honda Super Cub motorcycle. The most-produced car model is the Toyota Corolla, with at least 35 million made by 2010, by far, most vehicles use wheels which employ the principle of rolling to enable displacement with very little rolling friction. It is essential that a vehicle have a source of energy to drive it, energy can be extracted from the surrounding environment, as in the case of a sailboat, a solar-powered car or a streetcar. Energy can also be stored, in any form, provided it can be converted on demand, the most common type of energy source is fuel. Batteries also facilitate the use of motors, which have their own advantages. On the other hand, batteries have low densities, short service life, poor performance at extreme temperatures. Like fuel, batteries store energy and can cause burns

Movie theater
–
A movie theater or movie theatre is a venue, usually a building, that contains an auditorium for viewing films, for entertainment. Most, but not all, movie theaters are commercial operations catering to the general public, Some movie theaters, however, are operated by non-profit organizations or societies which charge members a membership fee to view films. The film is projected with a projector onto a large projection screen at the front of the auditorium while the dialogue, sounds. Since the 1970s, subwoofers have used for low-pitched sounds. In the 2010s, most movie theaters are equipped for digital cinema projection, removing the need to create, a great variety of films are shown at cinemas, ranging from animated films for children, blockbusters for general audiences and documentaries for patrons who are interested in non-fiction topics. The smallest movie theaters have a viewing room with a single screen. In the 2010s, most movie theaters have multiple screens, the largest theater complexes, which are called multiplexes—a design developed in the U. S. in the 1960s—have up to 25 screens. The audience members sit on padded seats which in most theaters are set up on a sloped floor. Movie theaters typically sell soft drinks, popcorn and candy and some theaters also sell hot fast food, in some jurisdictions, movie theaters are licensed to sell alcoholic drinks. A movie theater may also be referred to as a theatre, movie house, film house. In the US, theater has long been the preferred spelling, while in the UK, Canada, the latter terms, as well as their derivative adjectives cinematic and kinematic, ultimately derive from Greek κινῆμα, κινήματος —movement, motion. In the countries where those terms are used, the theatre is usually reserved for live performance venues. Colloquial expressions, mostly applied to motion pictures and motion picture theaters collectively, include the silver screen, specific to North American term is the movies, while specific terms in the UK are the pictures, the flicks and for the facility itself the flea pit. A screening room is a theater, often a private one. Open air place in ancient times for viewing spectacles and plays, the term theater comes from the Old French word theatre, from the 12th century and. The use of the theatre to mean a building where plays are shown dates from the 1570s in the English language. The earliest precursors to movies were magic lantern shows, magic lanterns used a glass lens, a shutter and a powerful lamp to project images from glass slides onto a white wall or screen. The invention of the Argand lamp in the 1790s, limelight in the 1820s, the magic lantern could project rudimentary moving images, which was achieved by the use of various types of mechanical slides

Aircraft
–
An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the lift of an airfoil. The human activity that surrounds aircraft is called aviation, crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as type, aircraft propulsion, usage. Each of the two World Wars led to technical advances. Consequently, the history of aircraft can be divided into five eras, Pioneers of flight, first World War,1914 to 1918. Aviation between the World Wars,1918 to 1939, Second World War,1939 to 1945. Postwar era, also called the jet age,1945 to the present day, aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large gasbags or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, a balloon was originally any aerostat, while the term airship was used for large, powered aircraft designs – usually fixed-wing. In 1919 Frederick Handley Page was reported as referring to ships of the air, in the 1930s, large intercontinental flying boats were also sometimes referred to as ships of the air or flying-ships. – though none had yet been built, the advent of powered balloons, called dirigible balloons, and later of rigid hulls allowing a great increase in size, began to change the way these words were used. Huge powered aerostats, characterized by an outer framework and separate aerodynamic skin surrounding the gas bags, were produced. There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a balloon is an aerostat and an airship is a powered one. A powered, steerable aerostat is called a dirigible, sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship. Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back and these soon became known as blimps. During the Second World War, this shape was adopted for tethered balloons, in windy weather

Seating assignment
–
In live entertainment, there are several possible schemes for the seating assignment of spectators. There are several schemes which are most commonly used, though there are no hard and fast rules, in a purely reserved seating scheme, each ticket is assigned a specific seat in the venue at the time of purchase. Seats are typically identified by row number/letter, seat number, reserved seating is the most common scheme used for large indoor venues such as stadia, arenas, and larger theatres. It is also common at other venues, as are other seating schemes, in a general admission scheme, each spectator has a ticket. However, the location from which they watch the event is determined upon arrival at the venue. General admission is most commonly employed in seat-less venues, such as outdoor festival shows and it is also sometimes used in seat-less sections of events that would otherwise have reserved seating. In some general admission events, a ticket may still assign the holder a specific section of the venue, general admission can also refer to a scheme in which seating is available, however, it is not pre-assigned. Typically in this scheme, seat selection is on a first-come, a common example of this scheme is most movie theatres in the United States. General admission events may be ticketed with no assigned number, or it may be purely first-come, first-served. Due to the first-come, first-served nature of the seating selection, festival seating typically refers to the form of general admission in which there is a large open area and all spectators must stand. Many music acts use festival seating because it allows the most enthusiastic fans to get near the stage, some performers and bands insist on a festival seating area near the stage. On December 3,1979, the Riverfront Coliseum in Cincinnati, eleven fans were killed and several dozen others injured in the rush for seating at the opening of a sold-out concert by The Who. The concert was using festival seating, the tragedy was blamed on poor crowd control, mainly the failure of arena management to open enough doors to deal with the crowd outside. As a result, concert venues across North America switched to assigned seating or changed their rules about festival seating. Cincinnati immediately outlawed festival seating at concerts, although it overturned the ban on August 4,2004, Cincinnati was the only city in the U. S. to outlaw festival seating altogether. Lawn seating refers to a method where concert-goers sit on the grass in the rear of the venue. Attendees can sometimes bring their own chairs, or rent them from vendors at the concert

In 2011, ESPNs history and rise was chronicled by These Guys Have All the Fun, Bill Rasmussen conceived the concept of ESPN in late May 1978, after he was fired from his job with the World Hockey Associations New England Whalers. One of the first steps in Bill and his son Scotts process was finding land to build the channels broadcasting facilities, the Rasmussens first rented office space in Plainville, Connecticut. However, the plan to base ESPN there was put on hold because a local ordinance prohibiting buildings from bearing rooftop satellite dishes and this helped the credibility of the fledgling company, however there were still many doubters to the viability of their sports channel concept. ESPN launched on September 7,1979, beginning with the first telecast of what would become the flagship program. Taped in front of a live audience inside the Bristol studios. ESPNs next big break came when the acquired the rights to broadcast coverage of the early rounds of the NCAA Mens Division I Basketball Tournament. It first aired the NCAA tournament in March 1980, creating the modern day television event known as March Madness. The channels tournament coverage also launched the career of Dick Vitale. In April of that year, ESPN created another made-for-TV spectacle, the next major stepping stone for ESPN came over the course of a couple of months in 1984. During this time period, the American Broadcasting Company purchased 100% of ESPN from the Rasmussens, for years, the NFL, NBA and Major League Baseball refused to consider cable as a means of broadcasting some of their games. However, with the backing of ABC, ESPNs ability to compete for major sports contracts greatly increased, later in 1984, the U. S. ESPNs Sunday Night Football games would become the highest-rated NFL telecasts for the next 17 years. In 1992, ESPN launched ESPN Radio, a sports talk radio network providing analysis. It became the fastest growing cable channel in the U. S. during the 1990s, ownership of ABC, and in effect control of ESPN, was acquired first by Capital Cities Communications in 1985, and then by The Walt Disney Company in 1996. In 2012, ESPN generated more revenue for Disney than any of its other properties combined, alongside its live sports broadcasts, ESPN also airs a variety of sports highlight, talk, and documentary-styled shows. 30 for 30 started airing in 2009 and continues airing to this day, each episode is through the eyes of a well known filmmaker and has featured some of the biggest directors in Hollywood
