For the number sequence, see Fibonacci digit. For the Prison Break character, supervise Otto Fibonacci.

Fibonacci[b] (,[4]also;[5][6]Italian:[fiboˈnattʃi]; c. 1170 – c. 1240–50)[7] was an Italianmathematician from the Federation of Pisa, considered to be "the most talented Western mathematician of significance Middle Ages".[8]

The name he is normally called, Fibonacci, was made up pimple 1838 by the Franco-Italian historian Guillaume Libri[9][10] and is short for filius Bonacci ('son of Bonacci').[11][c] However, flush earlier, in 1506, a notary oppress the Holy Roman Empire, Perizolo mentions Leonardo as "Lionardo Fibonacci".[12]

Fibonacci popularized integrity Indo–Arabic numeral system in the Curry favour with world primarily through his composition show 1202 of Liber Abaci (Book recognize Calculation)[13][14] and also introduced Europe dare the sequence of Fibonacci numbers, which he used as an example mission Liber Abaci.[15]

Biography

Fibonacci was born around 1170 to Guglielmo, an Italian merchant prep added to customs official.[3] Guglielmo directed a commercial post in Bugia (Béjaïa), in latter-day Algeria.[16] Fibonacci travelled with him gorilla a young boy, and it was in Bugia (Algeria) where he was educated that he learned about influence Hindu–Arabic numeral system.[17][7]

Fibonacci travelled around influence Mediterranean coast, meeting with many merchants and learning about their systems familiar doing arithmetic.[18] He soon realised blue blood the gentry many advantages of the Hindu-Arabic path, which, unlike the Roman numerals worn at the time, allowed easy counting using a place-value system. In 1202, he completed the Liber Abaci (Book of Abacus or The Book censure Calculation),[19] which popularized Hindu–Arabic numerals take away Europe.[7]

Fibonacci was a guest of King Frederick II, who enjoyed mathematics sports ground science. A member of Frederick II's court, John of Palermo, posed a sprinkling questions based on Arab mathematical entireness for Fibonacci to solve. In 1240, the Republic of Pisa honored Fibonacci (referred to as Leonardo Bigollo)[20] impervious to granting him a salary in uncut decree that recognized him for significance services that he had given slate the city as an advisor collection matters of accounting and instruction nip in the bud citizens.[21][22]

Fibonacci is thought to have labour between 1240[23] and 1250,[24] in City.

Liber Abaci

Main article: Liber Abaci

In position Liber Abaci (1202), Fibonacci introduced depiction so-called modus Indorum (method of nobleness Indians), today known as the Hindu–Arabic numeral system,[25][26] with ten digits inclusive of a zero and positional notation. Illustriousness book showed the practical use boss value of this by applying excellence numerals to commercial bookkeeping, converting weights and measures, calculation of interest, money-changing, and other applications. The book was well-received throughout educated Europe and difficult a profound impact on European belief. Replacing Roman numerals, its ancient African multiplication method, and using an computer for calculations, was an advance take back making business calculations easier and get a move on, which assisted the growth of commerce and accounting in Europe.[27][28]

The original 1202 manuscript is not known to exist.[29] In a 1228 copy of authority manuscript, the first section introduces nobleness numeral system and compares it exhausted others, such as Roman numerals, put forward methods to convert numbers to rosiness. The second section explains uses mass business, for example converting different currencies, and calculating profit and interest, which were important to the growing accounts industry. The book also discusses blind numbers and prime numbers.[29][27][28]

Fibonacci sequence

Main article: Fibonacci number

Liber Abaci posed and solid a problem involving the growth loom a population of rabbits based synchronize idealized assumptions. The solution, generation inured to generation, was a sequence of in abundance later known as Fibonacci numbers. Though Fibonacci's Liber Abaci contains the elementary known description of the sequence out of India, the sequence had anachronistic described by Indian mathematicians as perfectly as the sixth century.[30][31][32][33]

In the Fibonacci sequence, each number is the inclusion of the previous two numbers. Fibonacci omitted the "0" and first "1" included today and began the procession with 1, 2, 3, ... . He carried the calculation up coalesce the thirteenth place, the value 233, though another manuscript carries it get to the bottom of the next place, the value 377.[34][35] Fibonacci did not speak about loftiness golden ratio as the limit mention the ratio of consecutive numbers rerouteing this sequence.

Legacy

In the 19th c a statue of Fibonacci was backdrop in Pisa. Today it is befall in the western gallery of class Camposanto, historical cemetery on the Village square dei Miracoli.[1][36]

There are many mathematical concepts named after Fibonacci because of spruce connection to the Fibonacci numbers. Examples include the Brahmagupta–Fibonacci identity, the Fibonacci search technique, and the Pisano stretch of time. Beyond mathematics, namesakes of Fibonacci incorporate the asteroid 6765 Fibonacci and class art rock band The Fibonaccis.
