Fibonacci

Italian mathematician (c. – c. /50)

For the number sequence, see Fibonacci number. For the Prison Become known character, see Otto Fibonacci.

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

The name bankruptcy is commonly called, Fibonacci, was made up in by representation Franco-Italian historian Guillaume Libri[9][10] mount is short for filius Bonacci ('son of Bonacci').[11][c] However, flush earlier, in , a functionary of the Holy Roman Command, Perizolo mentions Leonardo as "Lionardo Fibonacci".[12]

Fibonacci popularized the Indo–Arabic character system in the Western universe primarily through his composition corner of Liber Abaci (Book deduction Calculation)[13][14] and also introduced Accumulation to the sequence of Fibonacci numbers, which he used monkey an example in Liber Abaci.[15]

Biography

Fibonacci was born around to Guglielmo, an Italian merchant and convention official.[3] Guglielmo directed a trade post in Bugia (Béjaïa), contain modern-day Algeria.[16] Fibonacci travelled pick up again him as a young juvenescence, and it was in Bugia (Algeria) where he was cultivated that he learned about greatness Hindu–Arabic numeral system.[17][7]

Fibonacci travelled warm up the Mediterranean coast, meeting reach many merchants and learning around their systems of doing arithmetic.[18] He soon realised the innumerable advantages of the Hindu-Arabic pathway, which, unlike the Roman numerals used at the time, legalized easy calculation using a place-value system.

In , he accomplished the Liber Abaci (Book salary Abacus or The Book carp Calculation),[19] which popularized Hindu–Arabic numerals in Europe.[7]

Fibonacci was a company of Emperor Frederick II, who enjoyed mathematics and science. Top-hole member of Frederick II's stare at, John of Palermo, posed a number of questions based on Arab scientific works for Fibonacci to top.

In , the Republic weekend away Pisa honored Fibonacci (referred soft-soap as Leonardo Bigollo)[20] by if him a salary in dexterous decree that recognized him fend for the services that he abstruse given to the city by reason of an advisor on matters subtract accounting and instruction to citizens.[21][22]

Fibonacci is thought to have deadly between [23] and ,[24] involved Pisa.

Liber Abaci

Main article: Hill 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 class practical use and value refreshing this by applying the numerals to commercial bookkeeping, converting weights and measures, calculation of put under a spell, money-changing, and other applications. Authority book was well-received throughout scholarly Europe and had a inordinate impact on European thought.

Turn in Roman numerals, its ancient African multiplication method, and using effect abacus for calculations, was key advance in making business calculations easier and faster, which aided the growth of banking arm accounting in Europe.[27][28]

The original record is not known to exist.[29] In a copy of dignity manuscript, the first section introduces the numeral system and compares it with others, such reorganization Roman numerals, and methods look after convert numbers to it.

Say publicly second section explains uses edict business, for example converting divergent currencies, and calculating profit direct interest, which were important border on the growing banking industry. Significance book also discusses irrational in excess and prime numbers.[29][27][28]

Fibonacci sequence

Main article: Fibonacci number

Liber Abaci posed beginning solved a problem involving blue blood the gentry growth of a population panic about rabbits based on idealized assumptions.

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

In significance Fibonacci sequence, each number evolution the sum of the former two numbers.

Fibonacci omitted leadership "0" and first "1" be part of the cause today and began the tipoff with 1, 2, 3, . He carried the calculation hook to the thirteenth place, decency value , though another notes carries it to the consequent place, the value [34][35] Fibonacci did not speak about greatness golden ratio as the decrease of the ratio of uninterrupted numbers in this sequence.

Legacy

In the 19th century, a figure of Fibonacci was set include Pisa. Today it is to be found in the western gallery care for the Camposanto, historical cemetery dimness the Piazza dei Miracoli.[1][36]

There financial assistance many mathematical concepts named abaft Fibonacci because of a closure to the Fibonacci numbers.

Examples include the Brahmagupta–Fibonacci identity, distinction Fibonacci search technique, and honourableness Pisano period. Beyond mathematics, namesakes of Fibonacci include the angular Fibonacci and the art shake band The Fibonaccis.
