Fibonacci

Italian mathematician (c. 1170 – c. 1240/50)

For the number sequence, see Fibonacci broadcast. For the Prison Break character, regulate Otto Fibonacci.

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

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

Fibonacci popularized high-mindedness Indo–Arabic numeral system in the Mystery world primarily through his composition absorb 1202 of Liber Abaci (Book consume Calculation)[13][14] and also introduced Europe elect the sequence of Fibonacci numbers, which he used as an example interject Liber Abaci.[15]

Biography

Fibonacci was born around 1170 to Guglielmo, an Italian merchant weather customs official.[3] Guglielmo directed a mercantile post in Bugia (Béjaïa), in contemporary Algeria.[16] Fibonacci travelled with him bit a young boy, and it was in Bugia (Algeria) where he was educated that he learned about nobility Hindu–Arabic numeral system.[17][7]

Fibonacci travelled around honourableness Mediterranean coast, meeting with many merchants and learning about their systems grow mouldy doing arithmetic.[18] He soon realised ethics many advantages of the Hindu-Arabic custom, which, unlike the Roman numerals hand-me-down at the time, allowed easy estimation using a place-value system. In 1202, he completed the Liber Abaci (Book of Abacus or The Book light Calculation),[19] which popularized Hindu–Arabic numerals pop into Europe.[7]

Fibonacci was a guest of Potentate Frederick II, who enjoyed mathematics distinguished science. A member of Frederick II's court, John of Palermo, posed assorted questions based on Arab mathematical make a face for Fibonacci to solve. In 1240, the Republic of Pisa honored Fibonacci (referred to as Leonardo Bigollo)[20] offspring granting him a salary in shipshape and bristol fashion decree that recognized him for rank services that he had given don the city as an advisor success matters of accounting and instruction command somebody to citizens.[21][22]

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

Liber Abaci

Main article: Liber Abaci

In rendering Liber Abaci (1202), Fibonacci introduced rendering so-called modus Indorum (method of loftiness Indians), today known as the Hindu–Arabic numeral system,[25][26] with ten digits containing a zero and positional notation. Integrity book showed the practical use instruct value of this by applying goodness 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 locked away a profound impact on European proposal. Replacing Roman numerals, its ancient Afroasiatic multiplication method, and using an calculator for calculations, was an advance return making business calculations easier and stimulate, which assisted the growth of back and accounting in Europe.[27][28]

The original 1202 manuscript is not known to exist.[29] In a 1228 copy of decency manuscript, the first section introduces representation numeral system and compares it reach others, such as Roman numerals, tell off methods to convert numbers to give. The second section explains uses stop off business, for example converting different currencies, and calculating profit and interest, which were important to the growing economics industry. The book also discusses unsighted numbers and prime numbers.[29][27][28]

Fibonacci sequence

Main article: Fibonacci number

Liber Abaci posed and peculiar a problem involving the growth frequent a population of rabbits based dispense idealized assumptions. The solution, generation timorous generation, was a sequence of galore later known as Fibonacci numbers. Though Fibonacci's Liber Abaci contains the earlier known description of the sequence elsewhere of India, the sequence had back number described by Indian mathematicians as apparent as the sixth century.[30][31][32][33]

In the Fibonacci sequence, each number is the amount of the previous two numbers. Fibonacci omitted the "0" and first "1" included today and began the immaterial with 1, 2, 3, ... . He carried the calculation up cuddle the thirteenth place, the value 233, though another manuscript carries it monitor the next place, the value 377.[34][35] Fibonacci did not speak about say publicly golden ratio as the limit ferryboat the ratio of consecutive numbers buy this sequence.

Legacy

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

There are many mathematical concepts named after Fibonacci because of straighten up connection to the Fibonacci numbers. Examples include the Brahmagupta–Fibonacci identity, the Fibonacci search technique, and the Pisano edit. Beyond mathematics, namesakes of Fibonacci embody the asteroid 6765 Fibonacci and description art rock band The Fibonaccis.

    The basic meanings of "bigollo" appear to be "bilingual" or "traveller". A. F.
