Deep Blue was a chess-playing computer developed by IBM. It was the first computer to win both a chess game and a chess match against a reigning world champion under regular time controls. Development for Deep Blue began in 1985 with the ChipTest project at Carnegie Mellon University; Grandmaster Joel Benjamin was part of the development team. IBM hired the development team when the project was briefly given the name Deep Thought. In 1989, it was renamed Deep Blue.

Menudo was one of the biggest Latin boy bands in history, releasing their first album in 1977. The band achieved much success, especially during the 1980s, becoming the most popular Latin American teen musical group of the era and selling some 20 million records worldwide. They are regarded as the Most Iconic Latino Pop Music Band. They also had several radio hits during its course. Their success led them to also release one television film (1979's Leyenda de Amor) and two feature films: Una aventura llamada Menudo and Menudo: La Película as well as to act in a telenovela named "Quiero Ser" and a television mini-series named . The band was a starting point for both Ricky Martin (1984–89) and Draco Rosa (1984–87), who were members around the mid-1980s during their youth. Menudo's original line-up consisted of two sets of brothers: Fernando and Nefty Sallaberry (12 and 13), from Ponce, Puerto Rico (Fernando was born in Spain); and the Melendez brothers, Carlos Meléndez, (12), Óscar Meléndez, (11), and Ricky Meléndez, (9); the latter three are Diaz's cousins. The band's golden-era lineup consisted of members Ricky Meléndez, Johnny Lozada, René Farrait, Miguel Cancel, Xavier Serbiá, Charlie Massó and Ray Reyes. The group disbanded in 2009 with a brief comeback in 2015. In 2019 Meléndez, Lozada, Farrait, Cancel and Reyes, came back for the "Súbete a Mi Moto Tour".

In mathematics, the power set (or powerset) of a set S is the set of all subsets of S, including the empty set and S itself. In axiomatic set theory (as developed, for example, in the ZFC axioms), the existence of the power set of any set is postulated by the axiom of power set. The power set of S is variously denoted as P(S), 𝒫(S), P(S), ℙ(S), ℘(S) (using the "Weierstrass p"), or 2S. The notation 2S is used because given any set with exactly n elements, the power set of S is a set containing exactly 2n elements. Any subset of P(S) is called a family of sets over S.

Deep Blue won its first game against world champion Garry Kasparov in game one of a six-game match on 10 February 1996. However, Kasparov won three and drew two of the following five games, defeating Deep Blue by a score of 4–2. Deep Blue was heavily upgraded before playing against Kasparov again in May 1997. Deep Blue won game six, thereby winning the six-game rematch 3½–2½ and becoming the first computer system to defeat a reigning world champion in a match under standard chess tournament time controls. However, Kasparov accused IBM of cheating.
