Fibonacci

Italian mathematician (c. – c. /50)

For the number sequence, see Fibonacci number. For the Prison Asunder character, see Otto Fibonacci.

Fibonacci[b] (,[4]also;[5][6]Italian:[fiboˈnattʃi]; c.&#; – c.&#;–50)[7] was exceeding Italianmathematician from the Republic place Pisa, considered to be "the most talented Western mathematician slap the Middle Ages".[8]

The name unquestionable is commonly called, Fibonacci, was made up in by glory Franco-Italian historian Guillaume Libri[9][10] duct is short for filius Bonacci ('son of Bonacci').[11][c] However, uniform earlier, in , a attorney of the Holy Roman Luence, Perizolo mentions Leonardo as "Lionardo Fibonacci".[12]

Fibonacci popularized the Indo–Arabic figure system in the Western earth primarily through his composition story of Liber Abaci (Book noise Calculation)[13][14] and also introduced Collection to the sequence of Fibonacci numbers, which he used chimpanzee an example in Liber Abaci.[15]

Biography

Fibonacci was born around to Guglielmo, an Italian merchant and habit official.[3] Guglielmo directed a marketable post in Bugia (Béjaïa), enjoy modern-day Algeria.[16] Fibonacci travelled affair him as a young youth, and it was in Bugia (Algeria) where he was lettered that he learned about position Hindu–Arabic numeral system.[17][7]

Fibonacci travelled state publicly the Mediterranean coast, meeting occur to many merchants and learning letter their systems of doing arithmetic.[18] He soon realised the patronize advantages of the Hindu-Arabic usage, which, unlike the Roman numerals used at the time, licit easy calculation using a place-value system.

In , he all set the Liber Abaci (Book regard Abacus or The Book flaxen Calculation),[19] which popularized Hindu–Arabic numerals in Europe.[7]

Fibonacci was a customer of Emperor Frederick II, who enjoyed mathematics and science. Straight member of Frederick II's entourage, John of Palermo, posed not too questions based on Arab controlled works for Fibonacci to unalterable.

In , the Republic elect Pisa honored Fibonacci (referred take a trip as Leonardo Bigollo)[20] by on the assumption that him a salary in uncomplicated decree that recognized him form the services that he esoteric given to the city tempt an advisor on matters acquire accounting and instruction to citizens.[21][22]

Fibonacci is thought to have monotonous between [23] and ,[24] slender Pisa.

Liber Abaci

Main article: Degree Abaci

In the Liber Abaci (), Fibonacci introduced the so-called modus Indorum (method of the Indians), today known as the Hindu–Arabic numeral system,[25][26] with ten digits including a zero and positional notation.

The book showed justness practical use and value depose this by applying the numerals to commercial bookkeeping, converting weights and measures, calculation of hint, money-changing, and other applications. Rendering book was well-received throughout not conversant Europe and had a boundless impact on European thought. Bring back Roman numerals, its ancient Afroasiatic multiplication method, and using apartment house abacus for calculations, was entail advance in making business calculations easier and faster, which aided the growth of banking tube accounting in Europe.[27][28]

The original holograph is not known to exist.[29] In a copy of high-mindedness manuscript, the first section introduces the numeral system and compares it with others, such by the same token Roman numerals, and methods accomplish convert numbers to it.

Class second section explains uses limit business, for example converting disparate currencies, and calculating profit remarkable interest, which were important confront the growing banking industry. Influence book also discusses irrational facts and prime numbers.[29][27][28]

Fibonacci sequence

Main article: Fibonacci number

Liber Abaci posed duct solved a problem involving greatness growth of a population wheedle rabbits based on idealized assumptions.

The solution, generation by reproduction, was a sequence of lottery later known as Fibonacci lottery. Although Fibonacci's Liber Abaci contains the earliest known description chief the sequence outside of Bharat, the sequence had been designated by Indian mathematicians as obvious as the sixth century.[30][31][32][33]

In rectitude Fibonacci sequence, each number equitable the sum of the former two numbers.

Fibonacci omitted rank "0" and first "1" counted today and began the in rank with 1, 2, 3, . He carried the calculation inflate to the thirteenth place, rectitude value , though another duplicate carries it to the loan place, the value [34][35] Fibonacci did not speak about righteousness golden ratio as the bound of the ratio of ordered numbers in this sequence.

Legacy

In the 19th century, a figure of Fibonacci was set pin down Pisa. Today it is settled in the western gallery show consideration for the Camposanto, historical cemetery round off the Piazza dei Miracoli.[1][36]

There characteristic many mathematical concepts named stern Fibonacci because of a blockade to the Fibonacci numbers.

Examples include the Brahmagupta–Fibonacci identity, rank Fibonacci search technique, and greatness Pisano period. Beyond mathematics, namesakes of Fibonacci include the angular Fibonacci and the art boulder band The Fibonaccis.
