Mexican inventions and discoveries are objects, processes or techniques invented or discovered, partially or entirely, by a person from Mexico.
 These also include concepts or practices introduced by Mexican people and their indigenous ancestors.
 Some of the objects, processes or techniques developed in the Pre-Columbian era were also invented or discovered independently in other cultures.
 This list shows only the ones which were introduced in present-day Mexican territory before anywhere else or those which vary significantly in concept, figure or use.
Chun Myung-hoon (born April 6, 1978) is a South Korean singer, rapper, actor and television presenter.
 He was a member of boy band NRG.
 He released his single, "Welcome To The Jungle" on October 19, 2012.
 He is well known for a cast member on several TV shows include "Girl Spirit".
The numerical renormalization group (NRG) is a technique devised by Kenneth Wilson to solve certain many-body problems where quantum impurity physics plays a key role.
Associativity-based routing (commonly known as ABR) is a mobile routing protocol invented for wireless ad hoc networks or also known as mobile ad hoc networks (MANETs) and wireless mesh network.
 ABR was invented in 1993, filed for a USA patent in 1996, and granted the patent in 1999.
 ABR was invented by Chai Keong Toh while doing his Ph.D. at Cambridge University.
 In the 1990s, our Internet is still largely wired.
 Toh was working on a different Internet – that of a rapidly deployable, infrastructureless, self-organizing, self-configuring mobile Internet.
 The challenges in such a network is mobility of nodes and link dynamics.
 Toh's prime argument is that there is no point in choosing a node to route packets if the route is unstable or going to be broken soon.
 So, he introduced a new routing metric (known as associativity ticks) and the concept of associativity, i.e., link stability among nodes over TIME and SPACE.
 Hence, ABR was born.
A clerihew ( ) is a whimsical, four-line biographical poem invented by Edmund Clerihew Bentley.
 The first line is the name of the poem's subject, usually a famous person put in an absurd light, or revealing something unknown or spurious about them.
 The rhyme scheme is AABB, and the rhymes are often forced.
 The line length and metre are irregular.
 Bentley invented the clerihew in school and then popularized it in books.
 One of his best known is this (1905):
Andrey Romanov (Russian: Андрей Романов , born 10 July 1979 in Moscow) is a Russian auto racing driver and director of MTV/NRG.
Joe Gilmore (19 May 1922 – 18 December 2015) was one of the longest running Head Barmen at The Savoy Hotel's American Bar.
 He was born in Belfast and moved to London in 1938.
 Gilmore started as a trainee barman at The American Bar in 1940 and was appointed Head Barman in 1955, a position he held until he retired in 1976.
 Over his years as Head Barman, Gilmore invented numerous cocktails to mark special events and important guests, a longstanding tradition at the American Bar.
 Gilmore has invented cocktails in honor of a number of royalty, politicians and celebrities including The Prince of Wales, Prince William, The Princess Anne, Queen Elizabeth The Queen Mother, The Prince Andrew, Sir Winston Churchill, and American Presidents Harry S. Truman and Richard Nixon.
 He also invented cocktails to commemorate the first walk on the moon in 1969 by Neil Armstrong, and the American and Russian link-up in space in 1975.
A pelican crossing (previously Pelicon Crossing – PEdestrian LIght CONtrolled Crossing) is a type of pedestrian crossing, which features a pair of poles each with a standard set of traffic lights facing oncoming traffic, a push button and two illuminated, coloured pictograms facing the pedestrian from across the road.
 These are a red, stationary person to indicate that it is not safe to cross, and a green, walking person to indicate that it is safe to do so.
 Pelican crossings also provide non-visual indication that it is safe to cross, such as a beep, vibrating button or tactile rotating cone in order to assist visually impaired pedestrians.
 Usage of pelican crossings is confined mainly to Great Britain, where they were invented, and in Ireland.
 A comparable system called the HAWK beacon is used in America.
Kenneth Geddes "Ken" Wilson (June 8, 1936 – June 15, 2013) was an American theoretical physicist and a pioneer in leveraging computers for studying particle physics.
 He was awarded the 1982 Nobel Prize in Physics for his work on phase transitions—illuminating the subtle essence of phenomena like melting ice and emerging magnetism.
 It was embodied in his fundamental work on the renormalization group.
Boardsports are sports that are played with some sort of board as the primary equipment.
 These sports take place on a variety of terrain, from paved flat-ground and snow-covered hills to water and air.
 Most boardsports are considered action sports or extreme sports, and thus often appeal to youth.
 A large proportion of youth partaking in these sports, together with aesthetic damage to property from sports like skateboarding, has led to many board sports being marginalized by the greater world of sports in the past.
 However, many board sports are ever-more frequently gaining mainstream recognition, and with this recognition have enjoyed wider broadcast, sponsorship and inclusion in institutional sporting events, including the Olympic Games.
 Surfing was the first boardsport, originating from Polynesian culture.
 Skateboarding was then invented by surfers looking to "surf" on land.
 It is hard to estimate when most boardsports were "invented" because people have been making homemade versions throughout history.
 For example, it is not hard to conceive of a person, who is familiar with the concept of skiing or sledding, standing sideways on a plank of wood and riding down a snow-covered slope.
 M.J. "Jack" Burchett is credited with first doing this in 1929, using horse reins and clothesline to secure his feet on the plank of wood.
 Most boardsports have similar, equally unknown origins.
 Using data collected in the past decade, it is estimated there are 18-50 million skateboarders, 5-25 million surfers.
 and 10-20 million snowboarders in the world.
 Approximately 100 million people participate in boardsports worldwide.
