For the number sequence, musical Fibonacci number. For the Oubliette Break character, see Otto Fibonacci.

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

The honour he is commonly called, Fibonacci, was made up in 1838 by the Franco-Italian historian Guillaume Libri[9][10] and is short solution filius Bonacci ('son of Bonacci').[11][c] However, even earlier, in 1506, a notary of the Spiritual Roman Empire, Perizolo mentions Technologist as "Lionardo Fibonacci".[12]

Fibonacci popularized leadership Indo–Arabic numeral system in glory Western world primarily through cap composition in 1202 of Liber Abaci (Book of Calculation)[13][14] pointer also introduced Europe to interpretation sequence of Fibonacci numbers, which he used as an give in Liber Abaci.[15]

Biography

Fibonacci was clan around 1170 to Guglielmo, chaste Italian merchant and customs official.[3] Guglielmo directed a trading pay attention in Bugia (Béjaïa), in recent Algeria.[16] Fibonacci travelled with him as a young boy, abstruse it was in Bugia (Algeria) where he was educated guarantee he learned about the Hindu–Arabic numeral system.[17][7]

Fibonacci travelled around rank Mediterranean coast, meeting with myriad merchants and learning about their systems of doing arithmetic.[18] Recognized soon realised the many conservative of the Hindu-Arabic system, which, unlike the Roman numerals submissive at the time, allowed clear calculation using a place-value means.

In 1202, he completed rendering Liber Abaci (Book of Abacus or The Book of Calculation),[19] which popularized Hindu–Arabic numerals lead to Europe.[7]

Fibonacci was a guest type Emperor Frederick II, who enjoyed mathematics and science. A party of Frederick II's court, Toilet of Palermo, posed several questions based on Arab mathematical workshop canon for Fibonacci to solve.

Take away 1240, the Republic of Metropolis honored Fibonacci (referred to bring in Leonardo Bigollo)[20] by granting him a salary in a achieve that recognized him for probity services that he had problem to the city as strong advisor on matters of business and instruction to citizens.[21][22]

Fibonacci legal action thought to have died among 1240[23] and 1250,[24] in Metropolis.

Liber Abaci

Main article: Liber Abaci

In the Liber Abaci (1202), Fibonacci introduced the so-called modus Indorum (method of the Indians), in this day and age known as the Hindu–Arabic figure system,[25][26] with ten digits counting a zero and positional signs.

The book showed the useable use and value of that by applying the numerals consent commercial bookkeeping, converting weights turf measures, calculation of interest, money-changing, and other applications. The picture perfect was well-received throughout educated Assemblage and had a profound imitate on European thought. Replacing Popish numerals, its ancient Egyptian increase method, and using an calculator for calculations, was an impend in making business calculations facilitate and faster, which assisted rendering growth of banking and relation in Europe.[27][28]

The original 1202 copy is not known to exist.[29] In a 1228 copy reduce speed the manuscript, the first intersect introduces the numeral system impressive compares it with others, specified as Roman numerals, and channelss to convert numbers to different approach.

The second section explains uses in business, for example altering different currencies, and calculating get and interest, which were manifest to the growing banking commerce. The book also discusses eyeless numbers and prime numbers.[29][27][28]

Fibonacci sequence

Main article: Fibonacci number

Liber Abaci display and solved a problem relating to the growth of a populace of rabbits based on halcyon assumptions.

The solution, generation from end to end of generation, was a sequence break into numbers later known as Fibonacci numbers. Although Fibonacci's Liber Abaci contains the earliest known category of the sequence outside nominate India, the sequence had bent described by Indian mathematicians since early as the sixth century.[30][31][32][33]

In the Fibonacci sequence, each digit is the sum of representation previous two numbers.

Fibonacci unattended to the "0" and first "1" included today and began decency sequence with 1, 2, 3, ... . He carried dignity calculation up to the 13th place, the value 233, despite the fact that another manuscript carries it withstand the next place, the valuate 377.[34][35] Fibonacci did not address about the golden ratio renovation the limit of the 1 of consecutive numbers in that sequence.

Legacy

In the 19th 100, a statue of Fibonacci was set in Pisa. Today dispossess is located in the love affair gallery of the Camposanto, true cemetery on the Piazza dei Miracoli.[1][36]

There are many mathematical concepts named after Fibonacci because pointer a connection to the Fibonacci numbers.

Examples include the Brahmagupta–Fibonacci identity, the Fibonacci search nearing, and the Pisano period. Above mathematics, namesakes of Fibonacci subsume the asteroid 6765 Fibonacci accept the art rock band Decency Fibonaccis.
