| '''5''' ('''five''' {{IPAc-en|'|f|ai|v}}) is a [[number]], [[numeral system|numeral]], and [[glyph]]. It is the [[natural number]] following [[4 (number)|4]] and preceding [[6 (number)|6]].
| |
| | |
| ==In mathematics==
| |
| Five is the third [[prime number]]. Because it can be written as
| |
| 2<sup>2<sup>1</sup></sup>+1, five is classified as a [[Fermat number|Fermat prime]]; therefore a [[regular polygon]] with 5 sides (a regular [[pentagon]]) is [[constructible polygon|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 <math>3n - 1</math>. It is also the only number that is part of more than one pair of [[twin prime]]s. 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 (number)|2]] plus [[3 (number)|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), ... ({{OEIS2C|id=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 number]]s.
| |
| | |
| In bases 10 and 20, 5 is a 1-[[automorphic number]].
| |
| | |
| 5 and 6 form a [[Ruth–Aaron pair]] under either definition.
| |
| | |
| There are five solutions to [[Znám's problem]] of length 6.
| |
| | |
| Five is the second [[Sierpinski number]] of the first kind, and can be written as S2=(2<sup>2</sup>)+1
| |
| | |
| While [[polynomial]] equations of degree [[4 (number)|4]] and below can be solved with radicals, equations of degree 5 and higher cannot generally be so solved. This is the [[Abel–Ruffini theorem]]. This is related to the fact that the [[symmetric group]] ''S''<sub>''n''</sub> is a [[solvable group]] for ''n'' ≤ 4 and not solvable for ''n'' ≥ 5.
| |
| | |
| While all [[graph theory|graphs]] with 4 or fewer vertices are [[planar graph|planar]], there exists a graph with 5 vertices which is not planar: ''K''<sub>5</sub>, the [[complete graph]] with 5 vertices.
| |
| | |
| Five is also the number of [[Platonic solid]]s.<ref>Bryan Bunch, ''The Kingdom of Infinite Number''. New York: W. H. Freeman & Company (2000): 61</ref>
| |
| | |
| A [[polygon]] with five sides is a [[pentagon]]. [[Figurate number]]s representing pentagons (including five) are called [[pentagonal number]]s. Five is also a [[square pyramidal number]].
| |
| | |
| Five is the only prime number to end in the digit 5, because all other numbers written with a 5 in the ones-place under the decimal system are multiples of five. As a consequence of this, 5 is in base 10 a 1-[[automorphic number]].
| |
| | |
| [[fraction (mathematics)#Vulgar, proper, and improper fractions|Vulgar fraction]]s with 5 or [[2 (number)|2]] in the [[fraction (mathematics)|denominator]] do not yield infinite [[decimal]] expansions, unlike expansions with all other prime denominators, because they are prime factors of [[10 (number)|ten]], the base. When written in the decimal system, all multiples of 5 will end in either 5 or [[0 (number)|0]].
| |
| | |
| There are five [[Simple Lie group#Exceptional cases|Exceptional Lie group]]s.
| |
| | |
| ==Evolution of the glyph==
| |
| [[File:Evolution5glyph.png|x50px|right]]
| |
| The evolution of our modern [[glyph]] for five cannot be neatly traced back to the Indians quite the same way it can for 1 to 4. Later on the Indian Empires of [[Kushan Empire|Kushana]] and [[Gupta Empire|Gupta]] from [[India]] had among themselves several different glyphs which bear no resemblance to the modern glyph. The [[Devanagari|Nagari]] and [[Punjabi language|Punjabi]] took these glyphs and all came up with glyphs that are similar to a lowercase "h" rotated 180°. The Ghubar Arabs transformed the glyph in several different ways, producing glyphs that were more similar to the numbers 4 or 3 than to the number 5.<ref>Georges Ifrah, ''The Universal History of Numbers: From Prehistory to the Invention of the Computer'' transl. David Bellos et al. London: The [[Harvill Press]] (1998): 394, Fig. 24.65</ref> It was from those characters that the Europeans finally came up with the modern 5, though from purely graphical evidence, it would be much easier to conclude that our modern 5 came from the [[Khmer numerals|Khmer]]. The Khmer glyph develops from the Kushana/Ândhra/Gupta numeral, its shape looking like a modern day version with an extended swirled 'tail' <ref>{{cite book|last=Ifrah|first=Georges|title=The universal history of numbers : from prehistory to the invention of the computer|year=1998|publisher=Harvill Press|location=London|isbn=978-1-86046-324-2|language=translated from the French by David Bellos ... [et al.]}}</ref>
| |
| | |
| While the shape of the 5 character has an [[Ascender (typography)|ascender]] in most modern [[typeface]]s, in typefaces with [[text figures]] the character usually has a [[descender]], as, for example, in [[File:TextFigs256.png]].

| |
| ;Christian
| |
| *There are traditionally [[Five Wounds]] of [[Jesus Christ]] in [[Christianity]]: the [[Flagellation of Christ|Scourging at the Pillar]], [[Crown of Thorns|the Crowning with Thorns]], the wounds in Christ's hands, the wounds in Christ's feet, and the [[Holy Lance|Side Wound]] of Christ.

| |
| | |
| ;Sikh
| |
| *The five sacred [[Sikh]] symbols prescribed by Guru Gobind Singh are commonly known as Panj Kakars or the 'Five Ks' because they start with letter K representing ''Kakka'' (ਕ) in the Punjabi language/''Gurmukhi'' Script. They are: Kesh (unshorn hair), Kangha (the comb), Kara (the steel bracelet), Kachhehra (the soldiers shorts), and Kirpan (the sword) [in ''Gurmukhi'' Script: ਕੇਸ, ਕੰਘਾ, ਕੜਾ, ਕਛਹਰਾ, ਕਿਰਪਾਨ]. Also, there are five deadly evils: Kam (lust), Krodh (anger), Moh (attachment), Lobh (greed), and Ankhar (ego).
| |
| | |
| ;Discordianism
| |
| *In [[Discordianism]], 5 is seen as a very important number. This is demonstrated in the [[Discordianism#Law of Fives|Law of Fives]], as well as in the [[Discordianism#Pentabarf|Pentabarf]], which contains five rules.
| |
| *Each page of the [[Principia Discordia]] —the primary religious document in Discordianism— is labeled with five digits.
| |
| | |
| ;Other
| |
| *According to ancient Greek philosophers such as [[Aristotle]], the universe is made up of five [[classical element]]s: [[water (classical element)|water]], [[earth (classical element)|earth]], [[air (classical element)|air]], [[fire (classical element)|fire]], and [[aether (classical element)|ether]]. This concept was later adopted by Medieval [[alchemists]] and more recently by practitioners of [[Neo-Pagan]] religions such as [[Wicca]].
| |
| *The [[pentagram]], or five-pointed star, bears religious significance in various faiths including [[Baha'i]], [[Christianity]], [[Satanism]], [[Taoism]], [[Thelema]], [[Freemasonry]] and [[Wicca]].
| |
| *In [[Cantonese]], "five" sounds like the word "not" (character: 唔). When five appears in front of a lucky number, e.g. "58", the result is considered unlucky.
| |
| *In [[East Asia]]n tradition, there are [[Wu Xing|five elements]]: ([[water (Wu Xing)|water]], [[fire (Wu Xing)|fire]], [[earth (Wu Xing)|earth]], [[tree (Wu Xing)|wood]], and [[metal (Wu Xing)|metal]]). The [[Japanese language|Japanese]] names for the [[week-day names|days of the week]], Tuesday through [[Saturday]], come from these elements via the identification of the elements with the [[Classical planet|five planets visible with the naked eye]]. Also, the traditional Japanese calendar has a five-day weekly cycle that can be still observed in printed mixed calendars combining Western, Chinese-Buddhist, and Japanese names for each weekday.
| |
| *Members of [[The Nation of Gods and Earths]], a primarily African American religious organization, call themselves the "Five-Percenters" because they believe that only 5% of mankind is truly enlightened.
| |
| | |
| ==Music==
| |
| *A [[perfect fifth]] is the most consonant harmony, and is the basis for most western tuning systems.
| |
| *Modern musical notation uses a [[staff (music)|musical staff]] made of five horizontal lines.
| |
| *In [[harmonic]]s – the fifth [[harmonic series (music)|partial]] (or 4th [[overtone]]) of a [[fundamental frequency|fundamental]] has a frequency ratio of 5/1 to the frequency of that fundamental. This ratio corresponds to the interval of 2 octaves + a pure major third. Thus, the interval of 5/4 is the interval of the pure third. A [[major and minor|major]] [[Triad (music)|triad]] [[chord (music)|chord]] when played in [[just intonation]] (most often the case in [[a cappella]] vocal ensemble singing), will contain such a pure major third.
| |
| *The number of completed, numbered piano concertos of [[Ludwig van Beethoven]], [[Sergei Prokofiev]], and [[Camille Saint-Saëns]].
| |
| *Using the Latin root, five musicians are called a quintet.

| ** In [[Major League Baseball]]:
| |
| *** The [[Baltimore Orioles]], for [[National Baseball Hall of Fame and Museum|Hall of Famer]] [[Brooks Robinson]].
| |
| *** The [[Cincinnati Reds]] have retired the number twice. The first was in 1940 for [[Willard Hershberger]], who committed suicide during the season. The number was returned to service in 1942, and was later retired a second time for Hall of Famer [[Johnny Bench]].
| |
| *** The [[Cleveland Indians]], for Hall of Famer [[Lou Boudreau]].
| |
| *** The [[Detroit Tigers]], for Hall of Famer [[Hank Greenberg]].

| |
| *** The [[History of the Miami Marlins|Florida Marlins]] retired the number for their first president [[Carl Barger]], who died in December 1992, four months before the team's first game. The number was chosen because DiMaggio was Barger's favorite player. When the team renamed itself the [[Miami Marlins]] in advance of its 2012 move to [[Marlins Park|a new stadium]], it decided to honor Barger with a plaque at the new park and placed the number into circulation.
| |

The Leafs have a unique policy of not retiring numbers unless the player honoured either died or suffered a career-ending incident while a member of the team. Barilko disappeared while on a fishing trip in 1951; his presumed death was confirmed when the wreckage of the plane he was on was discovered in a remote section of Ontario in 1962.
| |
| *** The [[Washington Capitals]], for Hall of Famer [[Rod Langway]].
| |
| ** In the [[National Football League|NFL]]:

| |
| **The [[Five-second rule (basketball)|"5-second rule"]] refers to several related rules designed to promote continuous play. In all cases, violation of the rule results in a turnover.
| |
| *** In all major rulesets, a team has 5 seconds to release the ball toward the court on a throw-in.
| |
| *** In all major rulesets except that of the NBA, a "closely guarded" player has 5 seconds to shoot, pass, or penetrate past the defender.

| *In [[Formula One]] racing, the number 5 & 6 cars traditionally belonged to the [[WilliamsF1|Williams]] team, until the end of the [[1995 Formula One season]]. It was most synonymous with [[Nigel Mansell]] in the late 1980s and early 1990s.
| |
| *In hockey, the area between the goaltender's legs is known as the [[five-hole]].

| |
| *On almost all devices with a [[numeric keypad]] such as telephones, computers, etc., the 5 key has a raised dot or raised bar to make dialing easier. Persons who are blind or have low vision find it useful to be able to feel the keys of a telephone. All other numbers can be found with their relative position around the 5 button (on computer keyboards, the 5 key of the [[numeric keypad|numpad]] has the raised dot or bar, but the 5 key that shifts with % does not).
