5 (number)

5 (five /ˈfaɪv/) is a number, numeral, and glyph. It is the natural number following 4 and preceding 6.

In mathematics

Five is the third prime number. Because it can be written as 2²¹ + 1, five is classified as a Fermat prime; therefore a regular polygon with 5 sides (a regular pentagon) is constructible with compass and unmarked straightedge. 5 is the third Sophie Germain prime, the first safe prime, the third Catalan number, and the third Mersenne prime exponent. Five is the first Wilson prime and the third factorial prime, also an alternating factorial. Five is the first good prime. It is an Eisenstein prime with no imaginary part and real part of the form 3n − 1. It is also the only number that is part of more than one pair of twin primes. Five is a congruent number.

Five is conjectured to be the only odd untouchable number and if this is the case then five will be the only odd prime number that is not the base of an aliquot tree.

The number 5 is the fifth Fibonacci number, being 2 plus 3. 5 is also a Pell number and a Markov number, appearing in solutions to the Markov Diophantine equation: (1, 2, 5), (1, 5, 13), (2, 5, 29), (5, 13, 194), (5, 29, 433), ... ( A030452 lists Markov numbers that appear in solutions where one of the other two terms is 5). Whereas 5 is unique in the Fibonacci sequence, in the Perrin sequence 5 is both the fifth and sixth Perrin numbers.

History

Formation and Swan Songs (2005–2009)

The band originated on June 3, 2005 as The Kids from a song titled "Hollywood" (Later released as "The Kids") that Jorel Decker (J-Dog), Aron Erlichman (Deuce), and Jeff Phillips (Shady Jeff) posted on the band's MySpace profile to positive reviews, leading them to form the group Hollywood Undead with their friends George "Johnny 3 Tears" Ragan, Jordon "Charlie Scene" Terrell, Dylan "Funny Man" Alvarez, and Matthew "Da Kurlzz" Busek. In an interview with Shave magazine, J-Dog explained that when forming the band "Whoever was in the room at the time and played an instrument was in the band." Phillips later left the group because of conflict with Erlichman.

Hungarian dance

Hungarian dance refers to the folk dances practised and performed by the Hungarians, both amongst the populations native to Hungary and its neighbours, and also amongst the Hungarian diaspora.

According to György Martin, a prominent folklore expert, Hungarian dances can be divided into two categories. The first refers to dances performed in the middle ages while the second relates to the 18th and 19th century.

Improvisation is often mentioned as being characteristic of Hungarian dance. "The peasant dance is not one which is set absolutely according to rule; the dancer constructs his steps according to his mood and ingenuity."

The most important stylistic feature of the dance within the Carpathians is the unusually large amount of personal improvisation. Observers have never failed to notice the individual nature of the Hungarian dance during the previous two centuries. This dancing is individual to such an extent that it is often difficult for scholars to establish the communal laws regulating individual creativity and improvising. Folk dance research has shown that this individuality is not merely poetic licence, but genuine features. Daniel Berzsenyi wrote, "Its secret laws are not ordered by craft. The laws are its own and enthusiasm sets the limit."
