Hello, today i'm going to present you the most incredible sport of USA: the American Football. I'll talk just about the rules on the field.
The field is 100 yards long, with 10 yards more on each parts for the touchdown area. A team is composed of 53 players, split in 3 squads of 11 players: the offensive team, the defensive team and the special team. A game is composed of 4 quarter times of 15 minutes each with an half-time in the middle. A game begin with a kick such as the rugby. When a team have the ball, it have to use its offensive squad on the field to do moving forward to the touchdown area. The other team have to use its defensive squad to avoid the adverse team to put a touchdown. To move the ball, a team have four downs (attempts) to do 10 yards, if it not succeed, it have to give the ball at the others team. For an offensive team, there are have two way to moving forward: the pass or the run.
-The pass: It is the quaterback who throw the ball to a reicever of his team who have to try to catch the ball and to run the farthest without being stoped by the other teams. In front of the quaterback, there is the offensive line which have to protect the quaterback of the defensive team to give him the time to throw the ball. Actually, if the defensive team reaches to lay down the quaterback with the ball in their hands, it enlarge the distance to succeed a down.
-The run: It is the running back who have to run through the defensive team to try to moving forward the farthest.
To score, a men must hold the ball on the touchdown area and it's is 6 points or kick the ball in the goal which looks like at the rugby goal and it's 3 points.

American football, referred to as football in the United States and Canada and also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins.

American football evolved in the United States, originating from the sports of soccer and rugby. The first American football match was played on November 6, 1869, between two college teams, Rutgers and Princeton, using rules based on the rules of soccer at the time. A set of rule changes drawn up from 1880 onward by Walter Camp, the "Father of American Football", established the snap, the line of scrimmage, eleven-player teams, and the concept of downs. Later rule changes legalized the forward pass, created the neutral zone and specified the size and shape of the football. The sport is closely related to Canadian football, which evolved in parallel with and at the same time as the American game (although their rules were developed independently from that of Camp's). Most of the features that distinguish American football from rugby and soccer are also present in Canadian football. The two sports are considered the primary variants of gridiron football.

American football is the most popular sport in the United States. The most popular forms of the game are professional and college football, with the other major levels being high school and youth football. As of 2012, nearly 1.1 million high school athletes and 70,000 college athletes play the sport in the United States annually. The National Football League, the most popular American football league, has the highest average attendance of any professional sports league in the world. Its championship game, the Super Bowl, ranks among the most-watched club sporting events in the world. The league has an annual revenue of around US$10 billion. Other professional leagues exist worldwide, but the sport does not have the international popularity of other American sports like baseball or basketball.

Etymology and names

In the United States, American football is referred to as "football". The term "football" was officially established in the rulebook for the 1876 college football season, when the sport first shifted from soccer-style rules to rugby-style rules. Although it could easily have been called "rugby" at this point, Harvard, one of the primary proponents of the rugby-style game, compromised and did not request the name of the sport be changed to "rugby". The terms " gridiron" or "American football" are favored in English-speaking countries where other types of football are popular, such as the United Kingdom, Ireland, New Zealand, and Australia.

Early history

American football evolved from the sports of soccer and rugby. Rugby, like American football, is a sport where two competing teams vie for control of a ball, which can be kicked through a set of goalposts or run into the opponent's goal area to score points.

What is considered to be the first American football game was played on November 6, 1869, between Rutgers and Princeton, two college teams. They consisted of 25 players each and used a round ball that could not be picked up or carried. It could, however, be kicked or batted with the feet, hands, head or sides, with the objective being to advance it into the opponent's goal. Rutgers won the game 6-4. Collegiate play continued for several years with matches played using the rules of the host school. Representatives of Yale, Columbia, Princeton and Rutgers met on October 19, 1873, to create a standard set of rules for use by all schools. Teams were set at 20 players each, and fields of 400 by 250 feet (122 m × 76 m) were specified. Harvard abstained from the conference, as they favored a rugby-style game that allowed running with the ball. After playing McGill University using both Canadian and American rules, the Harvard players preferred the Canadian style of having only 11 men on the field, running the ball without having to be chased by an opponent, the forward pass, tackling, and using an oblong instead of a round ball.

An 1875 Harvard-Yale game played under rugby-style rules was observed by two Princeton athletes who were impressed by it. They introduced the sport to Princeton, a feat the Professional Football Researchers Association compared to "selling refrigerators to Eskimos". Princeton, Harvard, Yale, and Columbia then agreed to intercollegiate play using a form of rugby union rules with a modified scoring system. These schools formed the Intercollegiate Football Association, although Yale did not join until 1879. Yale player Walter Camp, now regarded as the "Father of American Football", secured rule changes in 1880 that reduced the size of each team from 15 to 11 players and instituted the snap to replace the chaotic and inconsistent scrum.

Evolution of the game

The introduction of the snap resulted in an unexpected consequence. Prior to the snap, the strategy had been to punt if a scrum resulted in bad field position. However, a group of Princeton players realized that as the snap was uncontested, they could now hold the ball indefinitely to prevent their opponent from scoring. In 1881, in a game between Yale and Princeton, both teams used this strategy to maintain their undefeated records. Each team held the ball, gaining no ground, for an entire half, resulting in a 0-0 tie. This "block game" proved extremely unpopular with both teams' spectators and fans.

A rule change was necessary to prevent this strategy from taking hold, and a reversion to the scrum was considered. However, Camp successfully proposed a rule in 1882 that limited each team to three downs, or tackles, to advance the ball 5 yards (4.6 m). Failure to advance the ball the required distance within those three downs would result in control of the ball being forfeited to the other team. This change effectively made American football a separate sport from rugby, and the resulting five-yard lines added to the field to measure distances made it resemble a gridiron in appearance. Other major rule changes included a reduction of the field size to 110 by yards (100.6 m × 48.8 m) and the adoption of a scoring system that awarded four points for a touchdown, two for a safety and a goal following a touchdown, and five for a goal from the field. Additionally, tackling below the waist was legalized, and a static line of scrimmage was instituted.

Despite these new rules, football remained a violent sport. Dangerous mass-formations like the flying wedge resulted in serious injuries and deaths. A 1905 peak of 19 fatalities nationwide resulted in a threat by President Theodore Roosevelt to abolish the game unless major changes were made. In response, 62 colleges and universities met in New York City to discuss rule changes on December 28, 1905. These proceedings resulted in the formation of the Intercollegiate Athletic Association of the United States, later renamed the National Collegiate Athletic Association (NCAA).

The legal forward pass was introduced in 1906, although its impact was initially minimal due to the restrictions placed on its use. The idea of a 40-yard-wider field was opposed by Harvard due to the size of the new Harvard Stadium. Other rule changes introduced that year included the reduction of playing time from 70 to 60 minutes and an increase of the distance required for a first down from 5 to 10 yards (4.6 to 9.1 m). To reduce infighting and dirty play between teams, the neutral zone was created along the width of the football before the snap. Scoring was also adjusted: points awarded for field goals were reduced to three in 1909 and points for touchdowns were raised to six in 1912. The field was also shortened to 100 yards (91 m) long, but two 10-yard-long (9.1 m) end zones were created, and teams were given four downs instead of three to advance the ball 10 yards (9.1 m). The roughing the passer penalty was implemented in 1914, and eligible players were first allowed to catch the ball anywhere on the field in 1918.

Professional era

Over time, professional play became increasingly common, and with it came rising salaries and unpredictable player movement, as well as the illegal payment of college players who were still in school. The National Football League (NFL), a group of professional teams that was originally established in 1920 as the American Professional Football Association, aimed to solve these problems. This new league's stated goals included an end to bidding wars over players, prevention of the use of college players, and abolition of the practice of paying players to leave another team. By 1922, the NFL had established itself as America's premier professional football league.

The dominant form of football at the time was played at the collegiate level. The upstart NFL received a boost to its legitimacy in 1925, however, when an NFL team, the Pottsville Maroons, defeated a team of Notre Dame all-stars in an exhibition game. A greater emphasis on the passing game helped professional football to distinguish itself further from the college game during the late 1930s. Football, in general, became increasingly popular following the 1958 NFL Championship game, a match between the Baltimore Colts and the New York Giants that is still referred to as the "Greatest Game Ever Played". The game, a 23-17 overtime victory by the Colts, was seen by millions of television viewers and had a major impact on the popularity of the sport. This, along with the innovations introduced by the new American Football League (AFL) in the early 1960s, helped football to become the most popular sport in the United States by the mid-1960s.

The rival AFL arose in 1960 and challenged the NFL's dominance. The AFL began in relative obscurity but eventually thrived, with an initial television contract with the ABC television network. The AFL's existence forced the conservative NFL to expand to Dallas and Minnesota in an attempt to destroy the new league. Meanwhile, the AFL introduced many new features to professional football in the United States: official time was kept on a scoreboard clock rather than on a watch in the referee's pocket, as the NFL did; optional two-point conversions by pass or run after touchdowns; names on the jerseys of players; and several others, including expansion of the role of minority players, actively recruited by the league in contrast to the NFL. The AFL also signed several star college players who had also been drafted by NFL teams. Competition for players heated up in 1965, when the AFL New York Jets signed rookie Joe Namath to a then-record $437,000 contract (equivalent to $2.71 million in 2018). A five-year, $40 million NBC television contract followed, which helped to sustain the young league. The bidding war for players ended in 1966 when NFL owners approached the AFL regarding a merger, and the two leagues agreed on one that took full effect in 1970. This agreement provided for a common draft that would take place each year, and it instituted an annual World Championship game to be played between the champions of each league. This championship game began play at the end of the 1966 season. Once the merger was completed, it was no longer a championship game between two leagues and reverted to the NFL championship game, which came to be known as the Super Bowl.

College football maintained a tradition of postseason bowl games. Each bowl game was associated with a particular conference and earning a spot in a bowl game was the reward for winning a conference. This arrangement was profitable, but it tended to prevent the two top-ranked teams from meeting in a true national championship game, as they would normally be committed to the bowl games of their respective conferences. Several systems have been used since 1992 to determine a national champion of college football. The first was the Bowl Coalition, in place from 1992 to 1994. This was replaced in 1995 by the Bowl Alliance, which gave way in 1997 to the Bowl Championship Series (BCS). The BCS arrangement proved to be controversial, and was replaced in 2014 by the College Football Playoff (CFP).

Teams and positions

A football game is played between two teams of 11 players each. Playing with more on the field is punishable by a penalty. Teams may substitute any number of their players between downs; this "platoon" system replaced the original system, which featured limited substitution rules, and has resulted in teams utilizing specialized offensive, defensive and special teams units.

Individual players in a football game must be designated with a uniform number between 1 and 99. NFL teams are required to number their players by a league-approved numbering system, and any exceptions must be approved by the Commissioner. NCAA and NFHS teams are "strongly advised" to number their offensive players according to a league-suggested numbering scheme.

Although the sport is played almost exclusively by men, women are eligible to play in high school, college, and professional football. No woman has ever played in the NFL, but women have played in high school and college football games. In 2018, 1,100 of the 225,000 players in Pop Warner Little Scholars youth football were girls, and around 11% of the 5.5 million Americans who report playing tackle football are female according to the Sports and Fitness Industry Association. Women can also serve as officials; Sarah Thomas became the NFL's first female official in 2015.

Offensive unit

The role of the offensive unit is to advance the football down the field with the ultimate goal of scoring a touchdown.

The offensive team must line up in a legal formation before they can snap the ball. An offensive formation is considered illegal if there are more than four players in the backfield or fewer than five players numbered 50-79 on the offensive line. Players can line up temporarily in a position whose eligibility is different from what their number permits as long as they report the change immediately to the referee, who then informs the defensive team of the change. Neither team's players, except the center (C), are allowed to line up in or cross the neutral zone until the ball is snapped. Interior offensive linemen are not allowed to move until the snap of the ball.

The primary role of the halfback, also known as the running back or tailback, is to carry the ball on running plays. Halfbacks may also serve as receivers. Fullbacks tend to be larger than halfbacks and function primarily as blockers, but they are sometimes used as runners in short-yardage situations and are seldom used in passing situations.

The offensive line (OL) consists of several players whose primary function is to block members of the defensive line from tackling the ball carrier on running plays or sacking the quarterback on passing plays. The leader of the offensive line is the center, who is responsible for snapping the ball to the quarterback, blocking, and for making sure that the other linemen do their jobs during the play. On either side of the center are the guards (G), while tackles (T) line up outside the guards.

The principal receivers are the wide receivers (WR) and the tight ends (TE). Wide receivers line up on or near the line of scrimmage, split outside the line. The main goal of the wide receiver is to catch passes thrown by the quarterback, but they may also function as decoys or as blockers during running plays. Tight ends line up outside the tackles and function both as receivers and as blockers.

Defensive unit

Linebackers line up behind the defensive line but in front of the defensive backfield. They are divided into two types: middle linebackers (MLB) and outside linebackers (OLB). Linebackers are the defensive leaders and call the defensive plays. Their diverse roles include defending the run, pressuring the quarterback, and guarding backs, wide receivers and tight ends in the passing game.

The defensive backfield, often called the secondary, consists of cornerbacks (CB) and safeties (S). Safeties are themselves divided into free safeties (FS) and strong safeties (SS). Cornerbacks line up outside the defensive formation, typically opposite a receiver to be able to cover them. Safeties line up between the cornerbacks but farther back in the secondary. Safeties are the last line of defense and are responsible for stopping deep passing plays as well as running plays.

Special teams unit

The special teams unit is responsible for all kicking plays. The special teams unit of the team in control of the ball tries to execute field goal (FG) attempts, punts and kickoffs, while the opposing team's unit will aim to block or return them.

In football, the winner is the team that has scored more points at the end of the game. There are multiple ways to score in a football game. The touchdown (TD), worth six points, is the most valuable scoring play in American football. A touchdown is scored when a live ball is advanced into, caught in, or recovered in the opposing team's end zone. The scoring team then attempts a try or conversion, more commonly known as the point(s)-after-touchdown (PAT), which is a single scoring opportunity. A PAT is most commonly attempted from the two- or three-yard line, depending on the level of play. If a PAT is scored by a placekick or dropkick through the goal posts, it is worth one point, typically called the extra point. If it is scored by what would normally be a touchdown it is worth two points, typically called the two-point conversion. In general, the extra point is almost always successful while the two-point conversion is a much riskier play with a higher probability of failure; accordingly, extra point attempts are far more common than two-point conversion attempts.

A field goal (FG), worth three points, is scored when the ball is placekicked or dropkicked through the uprights and over the crossbars of the defense's goalposts. After a PAT attempt or successful field goal, the scoring team must kick the ball off to the other team.

A safety is scored when the ball carrier is tackled in their own end zone. Safeties are worth two points, which are awarded to the defense. In addition, the team that conceded the safety must kick the ball to the scoring team via a free kick.

Field and equipment

Football games are played on a rectangular field that measures 120 yards (110 m) long and yards (48.8 m) wide. Lines marked along the ends and sides of the field are known as the end lines and sidelines. Goal lines are marked 10 yards (9.1 m) inward from each end line.

Weighted pylons are placed the sidelines on the inside corner of the intersections with the goal lines and end lines. White markings on the field identify the distance from the end zone. Inbound lines, or hash marks, are short parallel lines that mark off 1-yard (0.91 m) increments. Yard lines, which can run the width of the field, are marked every 5 yards (4.6 m). A one-yard-wide line is placed at each end of the field; this line is marked at the center of the two-yard line in professional play and at the three-yard line in college play. Numerals that display the distance from the closest goal line in yards are placed on both sides of the field every ten yards.

Goalposts are located at the center of the plane of the two end lines. The crossbar of these posts is 10 feet (3.0 m) above the ground, with vertical uprights at the end of the crossbar 18 feet 6 inches (5.64 m) apart for professional and collegiate play, and 23 feet 4 inches (7.11 m) apart for high school play. The uprights extend vertically 35 feet (11 m) on professional fields, a minimum of 10 yards (9.1 m) on college fields, and a minimum of 10 feet (3.0 m) on high school fields. Goal posts are padded at the base, and orange ribbons are normally placed at the tip of each upright as indicators of wind strength and direction.

The football itself is an oval ball, similar to the balls used in rugby or Australian rules football. At all levels of play, the football is inflated to to pounds per square inch (86 to 93 kPa) and weighs 14 to 15 ounces (400 to 430 g); beyond that, the exact dimensions vary slightly. In professional play the ball has a long axis of 11 to inches (28 to 29 cm), a long circumference of 28 to inches (71 to 72 cm), and a short circumference of 21 to inches (53 to 54 cm). In college and high school play the ball has a long axis of to inches (27.6 to 29.1 cm), a long circumference of to inches (70 to 72 cm), and a short circumference of to inches (53 to 54 cm).

Duration and time stoppages

Football games last for a total of 60 minutes in professional and college play and are divided into two halves of 30 minutes and four quarters of 15 minutes. High school football games are 48 minutes in length with two halves of 24 minutes and four quarters of 12 minutes. The two halves are separated by a halftime period, and the first and third quarters are followed by a short break. Before the game starts, the referee and each team's captain meet at midfield for a coin toss. The visiting team can call either "heads" or "tails"; the winner of the toss chooses whether to receive or kick off the ball or which goal they wish to defend. They can defer their choice until the second half. Unless the winning team decides to defer, the losing team chooses the option the winning team did not select-to receive, kick, or select a goal to defend to begin the second half. Most teams choose to receive or defer, because choosing to kick the ball to start the game allows the other team to choose which goal to defend. Teams switch goals following the first and third quarters. If a down is in progress when a quarter ends, play continues until the down is completed.

Games last longer than their defined length due to play stoppages-the average NFL game lasts slightly over three hours. Time in a football game is measured by the game clock. An operator is responsible for starting, stopping and operating the game clock based on the direction of the appropriate official. A separate play clock is used to determine if a delay of game infraction has been committed. If the play clock expires before the ball has been snapped or free-kicked, a delay of game foul is called on the offense. The play clock is set 25 seconds after certain administrative stoppages in play and to 40 seconds when play is proceeding without such stoppages.

Advancing the ball and downs

There are two main ways the offense can advance the ball: running and passing. In a typical play, the center passes the ball backwards and between their legs to the quarterback in a process known as the snap. The quarterback then either hands the ball off to a back, throws the ball, or runs with it. The play ends when the player with the ball is tackled or goes out-of-bounds or a pass hits the ground without a player having caught it. A forward pass can be legally attempted only if the passer is behind the line of scrimmage; only one forward pass can be attempted per down. Like in rugby, players can also pass the ball backwards at any point during a play. In the NFL, a down also ends immediately if the runner's helmet comes off.

The offense is given a series of four plays, known as downs. If the offense advances ten or more yards in the four downs, they are awarded a new set of four downs. If they fail to advance ten yards, possession of the football is turned over to the defense. In most situations, if the offense reaches their fourth down they will punt the ball to the other team, which forces them to begin their drive from farther down the field; if they are in field goal range, they might attempt to score a field goal instead. A group of officials, the chain crew, keeps track of both the downs and the distance measurements. On television, a yellow line is electronically superimposed on the field to show the first down line to the viewing audience.

There are two categories of kicks in football: scrimmage kicks, which can be executed by the offensive team on any down from behind or on the line of scrimmage, and free kicks. The free kicks are the kickoff, which starts the first and third quarters and overtime and follows a try attempt or a successful field goal; the safety kick follows a safety.

On a kickoff, the ball is placed at the 35-yard line of the kicking team in professional and college play and at the 40-yard line in high school play. The ball may be drop-kicked or place-kicked. If a place kick is chosen, the ball can be placed on the ground or a tee; a holder may be used in either case. On a safety kick, the kicking team kicks the ball from their own 20-yard line. They can punt, drop-kick or place-kick the ball, but a tee may not be used in professional play. Any member of the receiving team may catch or advance the ball. The ball may be recovered by the kicking team once it has gone at least ten yards and has touched the ground or has been touched by any member of the receiving team.

The three types of scrimmage kicks are place kicks, drop kicks, and punts. Only place kicks and drop kicks can score points. The place kick is the standard method used to score points, because the pointy shape of the football makes it difficult to reliably drop kick. Once the ball has been kicked from a scrimmage kick, it can be advanced by the kicking team only if it is caught or recovered behind the line of scrimmage. If it is touched or recovered by the kicking team beyond this line, it becomes dead at the spot where it was touched. The kicking team is prohibited from interfering with the receiver's opportunity to catch the ball. The receiving team has the option of signaling for a fair catch, which prohibits the defense from blocking into or tackling the receiver. The play ends as soon as the ball is caught and the ball may not be advanced.

Officials and fouls

Officials are responsible for enforcing game rules and monitoring the clock. All officials carry a whistle and wear black-and-white striped shirts and black hats except for the referee, whose hat is white. Each carries a weighted yellow flag that is thrown to the ground to signal that a foul has been called. An official who spots multiple fouls will throw their hat as a secondary signal. The seven officials (of a standard seven-man crew; lower levels of play up to the college level use fewer officials) on the field are each tasked with a different set of responsibilities:

The referee is positioned behind and to the side of the offensive backs. The referee is charged with oversight and control of the game and is the authority on the score, the down number, and any rule interpretations in discussions among the other officials. The referee announces all penalties and discusses the infraction with the offending team's captain, monitors for illegal hits against the quarterback, makes requests for first-down measurements, and notifies the head coach whenever a player is ejected. The referee positions themselves to the passing arm side of the quarterback. In most games, the referee is responsible for spotting the football prior to a play from scrimmage.

The umpire is positioned in the defensive backfield, except in the NFL, where the umpire is positioned lateral to the referee on the opposite side of the formation. The umpire watches play along the line of scrimmage to make sure that no more than 11 offensive players are on the field before the snap and that no offensive linemen are illegally downfield on pass plays. The umpire monitors contact between offensive and defensive linemen and calls most of the holding penalties. The umpire records the number of timeouts taken and the winner of the coin toss and the game score, assists the referee in situations involving possession of the ball close to the line of scrimmage, determines whether player equipment is legal, and dries wet balls prior to the snap if a game is played in rain.

The back judge is positioned deep in the defensive backfield, behind the umpire. The back judge ensures that the defensive team has no more than 11 players on the field and determines whether catches are legal, whether field goal or extra point attempts are good, and whether a pass interference violation occurred. The back judge is also responsible for the play clock, the time between each play, when a visible play clock is not used.

The head linesman/down judge is positioned on one end of the line of scrimmage. The head linesman/down judge watches for any line-of-scrimmage and illegal use-of-hands violations and assists the line judge with illegal shift or illegal motion calls. The head linesman/down judge also rules on out-of-bounds calls that happen on their side of the field, oversees the chain crew and marks the forward progress of a runner when a play has been whistled dead.

The side judge is positioned twenty yards downfield of the head linesman. The side judge mainly duplicates the functions of the field judge. On field goal and extra point attempts, the side judge is positioned lateral to the umpire.

The line judge is positioned on the end of the line of scrimmage, opposite the head linesman. They supervise player substitutions, the line of scrimmage during punts, and game timing. The line judge notifies the referee when time has expired at the end of a quarter and notifies the head coach of the home team when five minutes remain for halftime. In the NFL, the line judge also alerts the referee when two minutes remain in the half. If the clock malfunctions or becomes inoperable, the line judge becomes the official timekeeper.

The field judge is positioned twenty yards downfield from the line judge. The field judge monitors and controls the play clock, counts the number of defensive players on the field and watches for offensive pass interference and illegal use-of-hands violations by offensive players. The field judge also makes decisions regarding catches, recoveries, the ball spot when a player goes out of bounds, and illegal touching of fumbled balls that have crossed the line of scrimmage. On field goal and extra point attempts, the field judge is stationed under the upright opposite the back judge.

The center judge is an eighth official used only in the top level of college football. The center judge stands lateral to the referee, the same way the umpire does in the NFL. The center judge is responsible for spotting the football after each play and has many of the same responsibilities as the referee, except announcing penalties.

Another set of officials, the chain crew, are responsible for moving the chains. The chains, consisting of two large sticks with a 10-yard-long chain between them, are used to measure for a first down. The chain crew stays on the sidelines during the game, but if requested by the officials they will briefly bring the chains on to the field to measure. A typical chain crew will have at least three people-two members of the chain crew will hold either of the two sticks, while a third will hold the down marker. The down marker, a large stick with a dial on it, is flipped after each play to indicate the current down and is typically moved to the approximate spot of the ball. The chain crew system has been used for over 100 years and is considered to be an accurate measure of distance, rarely subject to criticism from either side.

Safety and brain health

Football is a full-contact sport, and injuries are relatively common. Most injuries occur during training sessions, particularly ones that involve contact between players. To try to prevent injuries, players are required to wear a set of equipment. At a minimum players must wear a football helmet and a set of shoulder pads, but individual leagues may require additional padding such as thigh pads and guards, knee pads, chest protectors, and mouthguards. Most injuries occur in the lower extremities, particularly in the knee, but a significant number also affect the upper extremities. The most common types of injuries are strains, sprains, bruises, fractures, dislocations, and concussions.

Repeated concussions (and possibly sub-concussive head impacts) can increase a person's risk in later life for CTE ( chronic traumatic encephalopathy) and mental health issues such as dementia, Parkinson's disease, and depression. Concussions are often caused by helmet-to-helmet or upper-body contact between opposing players, although helmets have prevented more serious injuries such as skull fractures. Various programs are aiming to reduce concussions by reducing the frequency of helmet-to-helmet hits; USA Football's "Heads Up Football" program aims to reduce concussions in youth football by teaching coaches and players about the signs of a concussion, the proper way to wear football equipment and ensure it fits, and proper tackling methods that avoid helmet-to-helmet contact. However, a study in the Orthopaedic Journal of Sports Medicine found that Heads Up Football was ineffective; the same study noted that more extensive reforms implemented by Pop Warner Little Scholars and its member teams were effective in significantly reducing concussion rates.

A 2018 study performed by the VA Boston Healthcare System and the Boston University School of Medicine found that tackle football before age 12 was correlated with earlier onset of symptoms of CTE, but not with symptom severity. More specifically, each year a player played tackle football under age 12 predicted earlier onset of cognitive, behavioral, and mood problems by an average of two and a half years.

Leagues and tournaments

The National Football League (NFL) and the National Collegiate Athletic Association (NCAA) are the most popular football leagues in the United States. The National Football League was founded in 1920 and has since become the largest and most popular sport in the United States. The NFL has the highest average attendance of any sporting league in the world, with an average attendance of 66,960 during the 2011 NFL season. The NFL championship game is called the Super Bowl, and is among the biggest events in club sports worldwide. It is played between the champions of the National Football Conference (NFC) and the American Football Conference (AFC), and its winner is awarded the Vince Lombardi Trophy.

College football is the third-most popular sport in the United States, behind professional baseball and professional football. The NCAA, the largest collegiate organization, is divided into three Divisions: Division I, Division II and Division III. Division I football is further divided into two subdivisions: the Football Bowl Subdivision (FBS) and the Football Championship Subdivision (FCS). The champions of each level of play are determined through NCAA-sanctioned playoff systems; while the champion of Division I-FBS was historically determined by various polls and ranking systems, the subdivision adopted a four-team playoff system in 2014.

High school football is the most popular sport in the United States played by boys; over 1.1 million boys participated in the sport from 2007 to 2008 according to a survey by the National Federation of State High School Associations (NFHS). The NFHS is the largest organization for high school football, with member associations in all 50 states as well as the District of Columbia. USA Football is the governing body for youth and amateur football, and Pop Warner Little Scholars is the largest organization for youth football.

Other professional leagues

Several professional football leagues have been formed outside the auspices of the NFL. One such league, the XFL, is currently operating as of 2020.

Rival leagues

The most successful league to directly compete with the NFL was the American Football League (AFL), which existed from 1960 to 1969. The AFL became a significant rival in 1964 before signing a five-year, US$36 million television deal with NBC. AFL teams began signing NFL players to contracts, and the league's popularity grew to challenge that of the NFL. The two leagues merged in the 1970 season, and all the AFL teams joined the NFL. An earlier league, the All-America Football Conference (AAFC), was in play from 1946 to 1949. After it had dissolved, two AAFC teams, the Cleveland Browns and the San Francisco 49ers, became members of the NFL; another member, the Baltimore Colts joined the league, but folded after just a year in the NFL.

Other attempts to start rival leagues since the AFL merged with the NFL in 1970 have been far less successful, as professional football salaries and the NFL's television contracts began to escalate out of the reach of competitors and the NFL covered more of the larger cities. The World Football League (WFL) played for two seasons, in 1974 and 1975, but faced such severe monetary issues it could not pay its players. In its second and final season the WFL attempted to establish a stable credit rating, but the league disbanded before the season could be completed. The United States Football League (USFL) operated for three seasons from 1983 to 1985. Originally not intended as a rival league, the entry of owners who sought marquee talent and to challenge the NFL led to an escalation in salaries and ensuing financial losses. A subsequent US$1.5 billion antitrust lawsuit against the NFL was successful in court, but the league was awarded only $1 in damages, which was automatically tripled to $3 under antitrust law.

Complementary national leagues

The original XFL was created in 2001 by Vince McMahon and lasted for only one season. Despite television contracts with NBC and UPN, and high expectations, the XFL suffered from low quality of play and poor reception for its use of tawdry professional wrestling gimmicks, which caused initially high ratings and attendance to collapse. (The current XFL, also owned by McMahon, does not include those gimmicks.) The United Football League (UFL) began in 2009 but folded after suspending its 2012 season amid declining interest and lack of major television coverage. The Alliance of American Football lasted less than one season, unable to keep investors.

International play

American football leagues exist throughout the world, but the game has yet to achieve the international success and popularity of baseball and basketball. It is not an Olympic sport, but it was a demonstration sport at the 1932 Summer Olympics. At the international level, Canada, Mexico, and Japan are considered to be second-tier, while Austria, Germany, and France would rank among a third tier. These countries rank far below the United States, which is dominant at the international level.

NFL Europa, the developmental league of the NFL, operated from 1991 to 1992 and then from 1995 to 2007. At the time of its closure, NFL Europa had five teams based in Germany and one in the Netherlands. In Germany, the German Football League (GFL) has 16 teams and has operated for over 40 seasons, with the league's championship game, the German Bowl, closing out each season. The league operates in a promotion and relegation structure with German Football League 2 (GFL2), which also has 16 teams. The BIG6 European Football League functions as a continental championship for Europe. The competition is contested between the top six European teams.

American football federations are present in Africa, the Americas, Asia, Europe and Oceania; a total of 64 national football federations exist as of July 2012. The International Federation of American Football (IFAF), an international governing body composed of continental federations, runs tournaments such as the IFAF World Championship, the IFAF Women's World Championship, the IFAF U-19 World Championship and the Flag Football World Championship. The IFAF also organizes the annual International Bowl game. The IFAF has received provisional recognition from the International Olympic Committee (IOC). Several major obstacles hinder the IFAF goal of achieving status as an Olympic sport. These include the predominant participation of men in international play and the short three-week Olympic schedule. Large team sizes are an additional difficulty, due to the Olympics' set limit of 10,500 athletes and coaches. American football also has an issue with a lack of global visibility. Nigel Melville, the CEO of USA Rugby, noted that "American football is recognized globally as a sport, but it's not played globally." To solve these concerns, major effort has been put into promoting flag football, a modified version of American football, at the international level.

Popularity and cultural impact

United States

"Baseball is still called the national pastime, but football is by far the more popular sport in American society", according to ESPN.com's Sean McAdam. In a 2014 poll conducted by Harris Interactive, professional football ranked as the most popular sport, and college football ranked third behind only professional football and baseball; 46% of participants ranked some form of the game as their favorite sport. Professional football has ranked as the most popular sport in the poll since 1985, when it surpassed baseball for the first time. Professional football is most popular among those who live in the eastern United States and rural areas, while college football is most popular in the southern United States and among people with graduate and post-graduate degrees. Football is also the most-played sport by high school and college athletes in the United States. In a 2012 study, the NCAA estimated there were around 1.1 million high school football players and nearly 70,000 college football players in the United States; in comparison, the second-most played sport, basketball, had around 1 million participants in high school and 34,000 in college. The Super Bowl is the most popular single-day sporting event in the United States, and is among the biggest club sporting events in the world in terms of TV viewership. The NFL makes approximately $10 billion annually. Super Bowl games account for seven of the top eight most-watched broadcasts in American history; Super Bowl XLIX, played on February 1, 2015, was watched by a record 114.4 million Americans.

American football also plays a significant role in American culture. The day on which the Super Bowl is held is considered a de facto national holiday, and in parts of the country like Texas, the sport has been compared to a religion. Football is also linked to other holidays; New Year's Day is traditionally the date for several college football bowl games, including the Rose Bowl. However, if New Year's Day is on a Sunday, the bowl games are moved to another date so as not to conflict with the typical NFL Sunday schedule. Thanksgiving football is an American tradition, hosting many high school, college, and professional games. Steve Deace of wrote that Americans are passionate about football "because it embodies everything we love about American exceptionalism. Merit is rewarded, not punished. Masculinity is celebrated, not feminized. People of various beliefs and backgrounds - a melting pot, if you will - must unify for a common goal for the team to be successful". Implicit rules such as playing through pain and sacrificing for the better of the team are promoted in football culture.

The safety of the sport has also sparked national controversy in American popular culture. It is often received as "overly aggressive", and defamiliarized in popular culture. The 2015 film Concussion aimed to shed light on the sport's safety, specifically in the NFL by having Will Smith portray Dr. Bennet Omalu, a neuropathologist who was the first to discover and publish findings of chronic traumatic encephalopathy or CTE.

Other countries

In Canada, the game has a significant following. According to a 2013 poll, 21% of respondents said they followed the NFL "very closely" or "fairly closely", making it the third-most followed league behind the National Hockey League (NHL) and Canadian Football League (CFL). American football also has a long history in Mexico, which was introduced to the sport in 1896. It was the second-most popular sport in Mexico in the 1950s, with the game being particularly popular in colleges. The Los Angeles Times notes the NFL claims over 16 million fans in Mexico, which places the country third behind the US and Canada. American football is played in Mexico both professionally and as part of the college sports system. A professional league, the Liga de Fútbol Americano Profesional (LFA), was founded in 2016.

Japan was introduced to the sport in 1934 by Paul Rusch, a teacher and Christian missionary who helped to establish football teams at three universities in Tokyo. Play was halted during World War II, but the sport began growing in popularity again after the war. As of 2010, there are more than 400 high school football teams in Japan, with over 15,000 participants, and over 100 teams play in the Kantoh Collegiate Football Association (KCFA). The college champion plays the champion of the X-League (a semi-professional league where teams are financed by corporations) in the Rice Bowl to determine Japan's national champion.

Europe is a major target for the expansion of the game by football organizers. In the United Kingdom in the 1980s, the sport was popular, with the 1986 Super Bowl being watched by over four million people (about 1 out of every 14 Britons). Its popularity faded during the 1990s, coinciding with the establishment of the Premier League-top level of the English football league system. According to BBC America, there is a "social stigma" surrounding American football in the UK, with many Brits feeling the sport has no right to call itself "football" due to the lack of emphasis on kicking. Nonetheless, the sport has retained a following in the United Kingdom; the NFL operates a media network in the country, and since 2007 has hosted the NFL International Series in London. Super Bowl viewership has also rebounded, with over 4.4 million Britons watching Super Bowl XLVI. The sport is played in European countries like Switzerland, which has American football clubs in every major city, and Germany, where the sport has around 45,000 registered amateur players.

In Brazil, football is a growing sport. It was generally unknown there until the 1980s when a small group of players began playing on Copacabana Beach in Rio de Janeiro. The sport grew gradually with 700 amateur players registering within 20 years. Games were played on the beach with modified rules and without the traditional football equipment due to its lack of availability in Brazil. Eventually, a tournament, the Carioca championship, was founded, with the championship Carioca Bowl played to determine a league champion. The country saw its first full-pad game of football in October 2008. According to The Rio Times, the sport is one of the fastest-growing sports in Brazil and is almost as commonly played as soccer on the beaches of Copacabana and Botafogo.

Football in Brazil is governed by the Confederação Brasileira de Futebol Americano (CBFA), which had over 5,000 registered players as of November 2013. The sport's increase in popularity has been attributed to games aired on ESPN, which began airing in Brazil in 1992 with Portuguese commentary. The popularity and "easy accessibility" of non-contact versions of the sport in Brazil has led to a rise in participation by female players. According to ESPN, the American football audience in Brazil increased 800% between 2013 and 2016. The network, along with Esporte Interativo, airs games there on cable television. Football is often associated in Brazil as being the sport of supermodel Gisele Bündchen's husband Tom Brady. The NFL has expressed interest in having games in the country, and the Super Bowl has become a widely watched event in Brazil at bars and movie theaters.

Variations and related sports

Canadian football, the predominant form of football in Canada, is closely related to American football-both sports developed from rugby and are considered to be the chief variants of gridiron football. Although both games share a similar set of rules, there are several key rule differences: for example, in Canadian football the field measures 150 by 65 yards (137 by 59 m), including two 20-yard end zones (for a distance between goal lines of 110 yards), teams have three downs instead of four, there are twelve players on each side instead of eleven, fair catches are not allowed, and a rouge, worth a single point is scored if the offensive team kicks the ball out of the defense's end zone. The Canadian Football League (CFL) is the major Canadian league and is the second-most popular sporting league in Canada, behind the National Hockey League. The NFL and CFL had a formal working relationship from 1997 to 2006. The CFL has a strategic partnership with two American football leagues, the German Football League (GFL) and the Liga du Futbol Americano Professional (LFA). The Canadian rules were developed separately from the American game.

Indoor football leagues constitute what The New York Times writer Mike Tanier described as the "most minor of minor leagues." Leagues are unstable, with franchises regularly moving from one league to another or merging with other teams, and teams or entire leagues dissolving completely; games are only attended by a small number of fans, and most players are semi-professional athletes. The Indoor Football League is an example of a prominent indoor league. The Arena Football League, which was founded in 1987 and ceased operations in 2019, was one of the longest-lived indoor football leagues. In 2004, the league was called "America's fifth major sport" by ESPN The Magazine.

There are several non-contact variants of football like flag football. In flag football the ballcarrier is not tackled; instead, defenders aim to pull a flag tied around their waist. Another variant, touch football, simply requires the ballcarrier to be touched to be considered downed. Depending on the rules used, a game of touch football may require the player be touched with either one or two hands to be considered down.

Today, rap music is the type of music most listened in France, it is very popular for young people. Rap music breaks all the records, for example in 2017, 86 of the 200 most listened albums belong to the category of urban music. This music is also very and mainly listened on the streaming platforms like Spotify, Deezer or Appple Music. In this article, we are gonna first see the best French albums that came out in 2020, then we will learn who are the artists to follow this year and to finish we will learn some interesting facts about rap music and artists.

I.               The best French albums of 2020 (for the moment)

Actually, 90 albums came out in 2020, in 4 months. Of course I didn’t listen this 90 albums, because it’s a big number and all the artists are not really known. Even if I listened « only » 19 of the 90 albums and I don’t share everyone’s tastes, I think I can name the 10 best albums which came out this year.

1.     Ninho – M.I.L.S 3.   The french artist gave his sixth project, with the third M.I.L.S (a series of albums of the same name). With the Covid 19, this project didn’t came out in physical, but it didn’t stop it from selling 41 644 copies in the first week. In only 1 month and 1 day, this disc was certified platinum (more than 100 000 sales). This project is one of the best of 2020, because of the artist, the quality of the songs and the feats.

2.     DA Uzi – Architecte.   The young artist gave his first album, after a very successful mixtape in 2019. This album is one of the best I’ve ever listened, he chose to put 19 songs including 5 feats (Ninho, Maes, SCH, Mister You, Alonzo). His disc came out one week ago, so it’s not certified but I’m sure i twill be gold or platinum.

3.     Maes – LDS.   Maes, with his third album, gave his best project. His disc is actually certified platinum. Maes gave a 14 songs’ project, with 3 feats (Jul, Ninho, Booba). His album is really a good album, because the songs as the feats are really successful.

4.     Josman –  SPLIT.   Josman is not one of the most listened artists, but his album SPLIT is one oh the bests I have listened. Josman was inspired by the movie Split, which presents a man with 23 personalities. Josman have proposed 23 songs, showing 23 personalities. He invited 5 artists (Chily, Hamza, Zed, Seth Gueko, Leto) and proposed a very good album, maybe the most successful of his 5 projects.

5.     Mister V – MVP.   The youtuber and rapper gave his second album and the best one. His disc is actually certified gold. He put 18 songs in it, including 3 feats with PLK, Jul and Dosseh. This album is one of the best of the year, but I’m sure that Mister V can do even better even if MVP is already a very good album.

6.     Larry – Cité blanche.   Larry gave his first project and a very good one. Even if he is very young, if he’s an artist in whom we have a lot of hope and if he had a lot of pressure, he gave a good album. His disc is a great one but he can do better and he will.

7.     Timal – Caliente.   It is Timal’s second album, in line of his first album « Trop chaud ». He put 17 songs, including 3 feats (Maes, PLK, Leto). This album is a really good one, but Timal’s style is very particular and doesn’t please everyone.

8.     Bosh – Synkinisi.   Bosh is one of the actor of the series Validé, which gave him more visibility even if he’s not a very famous rapper. Bosh gave his second project and a very good one, with 15 songs including 3 feats (Tigers, SCH, Leroy Menace). This album is not for everyone, because it is in a dark ambiance.

9.     Soolking – Vintage.   Soolking gave his second project, in his particular style. The rapper chose to put 21 songs including 9 feats (Cheb Mami, Dadju, SCH, MERO, Heuss, Gambi, Jul/Kliff, 13 Block, Ghali). Soolking is an artist of summer and he showed it in his album.

10.  Junior Bvendo – Menace.   The young rapper gave his second album, with 19 songs including 5 feats (Popey, T2R, Driks, Guy 2 Bezbar, Shotas). Junior Bvendo gave a successful album, in his style. It’s not an incredible album but it’s a good one.

It was the 10 best albums of 2020, even if a lot of albums will come out in the next weeks and months.

II.               The 10 artists you have to follow this year

This year will be very interesting in rap music, some big artists will give their albums and some young artists will turn out. But this year you have to follow some of them. We will discover who and why.

1.     Ninho : Even if he has already gave a project this year, it’s important to take care of his activitie this year. Ninho broke all the records last year and will continue in 2020. He was in featuring on all the albums and his album Destin had a great success (2019). His mixtape M.I.L.S 3 had success this year and he maybe will do a second one. Moreover there are rumors about a joint album with Niska or Leto. So tahe care to his actuallity.

2.     Damso : Damso actually gave 3 projects and will give his maybe last album this year. The Belgian is one of the most important figures in francophone rap and if his next album is the last, you have to take care of him. Even if last year he wasn’t really present on the scene, he’s still there and will show it in 2020. Personnaly I look forward to this album.

3.     Zola : His first project came out in 2019 and what a project ! Zola gave an excellent album and has a very difficult task : do better or as well. When you gave a first project of this level it’s almost impossible not to disappoint its audience because people expects he will do better. So let’s se how Zola is gonna do to keep his project at the level of the previous one.

4.     Leto : Leto is not the most famous of the rappers but I think  he will be awesome this year. Leto’s last album was good but not as good as he can do and after that, he released songs in a different style and I think his community prefers this style. So let’s do what he will do with this and if he will answer to the expectations.

5.     Jul : Even if the rapper from Marseille is very criticized it’s impossible to deny that he’s a machine. He releases two or more albums per year, that’s incredible. In addition he will release a project named La Machine in June. So follow this monster of the music industry.

6.     PLK : PLK gave 2 successful projects in 2019 : an album and a mixtape. He became very popular and can’t disappoint his fans. He actually gave one album per year so even if he didn’t announce anything, we can think he will release an album in 2020. Even if he’s young, he’s an influential figure of the scene and he will be very waited.

7.     SCH : The French rapper surprised everyone in 2019, releasing his album Rooftop, when everyone thought he was going to release JVLIVS volume 2, the following of JVLIVS, an album across which he narrated the story of a fictive character inspired of his life named Julius. So let’s follow him and see if the volume 2 will release this year.

8.     Larry : The « Prince of Strasbourg », Larry, released his first project last year, a good album but not as good as he can do. So I can advise you to follow his actuallity this year, because he may will give a new album and we hope that he will do a very good album.

9.     Dinor rdt : Dinor rdt has the dream life of some people, he became famous in the rap and he’s in the training club of an Italian football club : Sassuolo. Concerning his rap carreer he gave his first album last year, a pretty goood one, and may will release a new one this year. So follow this young artist because he will do a good year.

10.  Vald : Vald is one of the most appreciated rappers in France it’s deserved. With a good voice and a good feather, Vald showed his talent in his 7 projects. Last year, according to me, he released his best album and I wait him this year because he can break the records. So let’s take care of his actuallity in 2020.

That was my 10 artists you have to follow in 2020, I hope you liked this list and you agree with it.

III.             Did you know it ?

For the last part of the article I will present 5 ianecdotes about French rap music.

1.     Ninho is the artist who has the biggest number of diamond singles, with 11 ones. In second place you have the duo PNL, with 10 ones.

2.     Ninho’s studio has been burnt recently. 3 platinum discs of the artist were exposed in.

3.     Sneazzy didn’t accept to be in featuring on Nekfeu’s album : Les étoiles vagabondes because Nekfeu didn’t go at Sneazzy’s birthday.

4.     Au DD, one of PNL’s songs, is the most listened music on Spotify France, dethroning Shape of you of Ed Sheeran.

Everybody knows what Formula 1 is in the big lines. But once you dig a little bit into this sport, you start to see what makes this incredible motorsport so unique. So, in this article, you will learn more about Formula 1, from its legendary drivers to its biggest events and understand why it is the most popular motorsport in the world.

How does a Formula 1 championship works?

Since 1950, every year, around 20 drivers and 10 teams compete for the World Drivers and Constructor Championship in single-seater cars. These cars are the very fastest race cars in the world, but we’ll get into that later. The “Formula” in the name refers to the different rules to which every car must conform and the “One” refers to the fact that the Formula 1 championship is the highest class of single-seater racing as there is also Formula 2,3 and 4. A Formula One season consists of a series of races called Grands Prix that takes place every week or two weeks on racetracks and sometimes street circuits. A Grand Prix consist of three phases that makes the Weekend.

It begins on Friday with 2 free practice sessions during which drivers can practice around the track and adapt their car’s settings for the race.

On Saturday, the last and third free practice session takes place as well as the qualifications session. During this session, the drivers try to make the fastest lap possible around the circuit to determine the grid (their starting place) for the race. So if you make the fastest and thus the shortest time, then you start first on the race’s grid, if you make the 13th shortest time then you start 13th on the grid and so on.

Finally, on Sunday, the main event takes place, the race where the goal is to be the first to finish all the laps around the track. You get points for the championship depending on what place you finished the race. Just like this:

You get a bonus point if you make the fastest lap of the race but only if you’re at 10th place minimum.

The Champion is the one with the most points at the end of the season. There are 2 drivers per team so a constructor’s points is the addition of it’s 2 drivers points.

A lot of people think that chess is an old and boring board game but it requires a lot of reflection, analytical skills and concentration. Moreover, it can help young people developing these faculties.

In the first part, I’m going to talk about the history of chess, when was it created? Where ? ... In a second part, I’ll teach you how to move of each piece. In the last part, I’m going to describe a chess game, the different steps, the most known techniques…

1)   The history of the game

The history of chess goes back to the 6th century but the place it was invented is still debated between Northern India, China or Persia. The game spread in the world with conquests and wars. When the Arabs conquered Persia, chess was taken up by the Muslim world which, later, spread it up to Europe.

The moves of the pieces changed a bit in the 16th century in Europe. But more than 1500 years later the game is still nearly the same. In the 20th century, chess theories advanced and the World Chess Federation was created. Currently, Chess engines and data bases are very important to perfectionate the players. In 1997, the current world champion Garry Kasparov, was beaten by Deep Blue in New-York, the dominance of computers in the chess world had just begun.

Hello dear readers,

In this article I am going to present you the diversity of the Basque Country in terms of sports landscapes and the quantity of great celebrations. I will also introduce you to his traditions. Just to present, the Basque Country is located in the southwest of France, it is a destination that has become very touristic because of its temperate climate and beautiful landscapes.

To introduce this, we are going to show you the diversity of the landscapes. You should know that in the Basque Country there is a great diversity of landscapes with cities such as Bayonne, coasts such as Biarritz and mountains such as Cambo-les-Bain. Its beautiful because all landscapes are very close, for example, the distance between Ustaritz and Biarritz is only 17 km as we go from the mountains to the sea. Also, the fauna is very varied on this vast territory. The flora of the Basque Country is varied and different according to altitude and climate. On the coast, the flora is adapted to the maritime conditions, so we can find gorse, heather, serapia tongue and sea crithme. The hilly landscape is dominated by grassy meadows and moorland.

Etienne: If you are in search of money, whether you want to increase your already full moneybox or you just have a few bucks you want to make benefits with, betting is an option you might want to consider. Bring a bit of luck with you and let me introduce you to the world of betting !

First of all, in this article I will talk about about sports betting, so just move on if you are not a little interested in sports.
I will especially talk about basketball and football, but you can just use what I will say for any sports you like.

As a betting beginner, you first must understand that bets where you will win 100,200€ are far from arriving like some famous influencers can show you. The safest way to win money in betting is to bet little by little, but I will talk about that later. For the moment, I will just give you a few advice.
First you must do some research about the sport you like: who are the best teams, the best scorers, the teams you mustn't sleep on, those that can deceive you ...
This is an important part in betting, it will clearly improve your chances of winning.
Then you must understand nothing is sure. The best team in the championship can lose to the worse one. But see it like that: the best team can lose one or twice, but their winning rate against weak teams is by far superior to 50%, so it will always be a good idea to bet on that, even if the odds are not the highest.

Egypt has been a wonderful country for over 4000 years, with a very interesting and complete history, that intrigued several historians. More than 200 pharaohs ruled these lands, building more and more impressive wonders, always higher, always bigger. But do you know why this country became a huge imposing and feared kingdom? And how a pharaoh became the leader of this nation? There is a specific reason, that will be explained in this article.

I) The organization of the country

Egypt is geographically part of Africa, but its culture seems to be closer to Middle East countries. In addition, most countries in North Africa were populated by nomadic people, who raised cattle in the desert, but the exception was Egypt, that had something precious, that made the country very rich, crossing its lands: The Nile. Indeed, the Egyptians were cultivators, contrary to other North African people, that lived in the desert.

The banks of the Nile were very green and damp, because once a year, the Nile floods submerged them. It was very good for culture, and here’s the point: all this activity required an organization, because of the floods, somebody that would control the culture, rule what to do during the Nile floods, the provisions, the exportation, separation of plots… This is why pharaohs appeared. A leader was needed, to rule the lands, the people and their plots.

First of all, a conspiracy theory is a different explanation of an event then the one that is official or of a different vision of the history. Conspiracy theories claims to be coherent and their purpose is to prove that a group of people is leading the world, acting in the shadows and committing illegal actions. This group of people can be known or not but they always hide the truth from us. Conspiracy theories have become more important and believed since the 20thcentury, although they have existed since the 18thcentury. Firstly, I will tell you the most famous conspiracy theories, secondly, I will explain why conspiracy theories are so much believed and finally I will conclude.

The most famous and believed conspiracy theory is the flat earth. There is a large community of flat earthers in the world but especially in the United States. The flat earth society believes that the fact that the Earth is a globe is a myth and is based on elements that it judges undeniable, which everyone can see. For example, one of their most solid evidence is that the sea level is horizontal, that we can’t see the end, and if the Earth was a globe, the sea would flow. It’s an element which has been scientifically disapproved. Another evidence of the flat earth is religious. In fact, in the Bible, it is written that the Earth is flat. The flat earth society also has explanations to things that proves that the Earth is flat, like the “Pac Man effect” which explain why airplanes don’t fall off the edge of the flat earth. A speaker named Darren Nesbit invented this “Pac Man effect” and said that when a plane or an object arrives at the edge of the horizon, like Pac Man reaches the end of the screen, that object is teleported from one side of the planet to the other. It is the most interesting evidence of the flat earth society, and it’s confirms that this community goes against science. Another conspiracy theory well known is the fact that nobody went on the Moon. It is said that the American government created this lie to show the American superiority on Russia in their space race, during the Cold War. They prove their theory with evidence like the flag that is fluttering in the video or the stars that we can’t see. These are the most famous conspiracy theories but there are a lot more like the murder of John F Kennedy which has been organized by the CIA or the existence of a secret society named the Illuminatis which are reptiles governing the United States. I will now explain why these theories are so much believed.
