Copa CONMEBOL

The Copa CONMEBOL (English: CONMEBOL Cup) was an annual football cup competition organized by CONMEBOL between 1992 and 1999 for South American football clubs. During its time of existence, it was a very prestigious South American club football contest, similar to the UEFA Cup. Clubs qualified for the competition based on their performance in their national leagues and cup competitions. Teams that were not able to qualify for the Copa Libertadores played in this tournament. The tournament was played as a knockout cup. The tournament ended in 1999, following the expansion of Copa Libertadores to 32 teams. The Copa Mercosur and Copa Merconorte, which both started in 1998, replaced the Copa CONMEBOL, and the merger of those three cups transformed in the current Copa Sudamericana, being all of them the precursors of the cup.

The last champion of the competition was Talleres, while Atlético Mineiro is the most successful club in the cup history, having won the tournament two times. The cup was won by seven different clubs but it was never won consecutively.

Collatz conjecture

The Collatz conjecture is a conjecture in mathematics named after Lothar Collatz, who first proposed it in 1937. The conjecture is also known as the 3n + 1 conjecture, the Ulam conjecture (after Stanisław Ulam), Kakutani's problem (after Shizuo Kakutani), the Thwaites conjecture (after Sir Bryan Thwaites), Hasse's algorithm (after Helmut Hasse), or the Syracuse problem; the sequence of numbers involved is referred to as the hailstone sequence or hailstone numbers (because the values are usually subject to multiple descents and ascents like hailstones in a cloud), or as wondrous numbers.

The conjecture can be summarized as follows. Take any positive integer n. If n is even, divide it by 2 to get n / 2. If n is odd, multiply it by 3 and add 1 to obtain 3n + 1. Repeat the process (which has been called "Half Or Triple Plus One", or HOTPO) indefinitely. The conjecture is that no matter what number you start with, you will always eventually reach 1. The property has also been called oneness.

Fox Sports

Fox Sports is the brand name for a number of sports channels, broadcast divisions, programming, and other media around the world that are either controlled or partially owned by the family of Rupert Murdoch. These assets are held mainly by 21st Century Fox, with the exception of the operations in Australia, which are part of News Corp Australia. (21st Century Fox and News Corp are the two companies resulting from the breakup of the larger News Corporation in mid-2013; the Murdoch family retains voting control of both entities.)

The name originates from the Fox Broadcasting Company in the United States, which in turn was derived from the name of the Fox Film Corporation (later 20th Century Fox). The Fox Sports name has since been used in 21st Century Fox's and News Corp's other sports media assets around the world.

Manchester United F.C.

Manchester United Football Club is a professional football club based in Old Trafford, Greater Manchester, England, that competes in the Premier League, the top flight of English football. Founded as Newton Heath LYR Football Club in 1878, the club changed its name to Manchester United in 1902 and moved to Old Trafford in 1910.

Manchester United have won 20 league titles, the most of any English club, 11 FA Cups, four League Cups and a record 20 FA Community Shields. The club has also won three European Cups, one UEFA Cup Winners' Cup, one UEFA Super Cup, one Intercontinental Cup and one FIFA Club World Cup. In 1998–99, the club became the first in the history of English football to achieve the treble of the Premier League, the FA Cup and the UEFA Champions League.

The 1958 Munich air disaster claimed the lives of eight players. In 1968, under the management of Matt Busby, Manchester United became the first English football club to win the European Cup. Alex Ferguson won 38 trophies, including 13 Premier League titles, 5 FA Cups and 2 UEFA Champions Leagues, between 1986 and 2013, when he announced his retirement. Louis van Gaal is the club's current manager after Ferguson's successor David Moyes was sacked after only 10 months in charge.
