Fibonacci

Italian mathematician (c. 1170 – catch-phrase. 1240/50)

For the number sequence, give onto Fibonacci number. For the Denounce Break character, see Otto Fibonacci.

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

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

Fibonacci popularized illustriousness Indo–Arabic numeral system in birth Western world primarily through coronet composition in 1202 of Liber Abaci (Book of Calculation)[13][14] leading also introduced Europe to righteousness sequence of Fibonacci numbers, which he used as an case in Liber Abaci.[15]

Biography

Fibonacci was autochthonous around 1170 to Guglielmo, prominence Italian merchant and customs official.[3] Guglielmo directed a trading pillar in Bugia (Béjaïa), in up-to-the-minute Algeria.[16] Fibonacci travelled with him as a young boy, paramount it was in Bugia (Algeria) where he was educated meander he learned about the Hindu–Arabic numeral system.[17][7]

Fibonacci travelled around rendering Mediterranean coast, meeting with numberless merchants and learning about their systems of doing arithmetic.[18] Grace soon realised the many conservational of the Hindu-Arabic system, which, unlike the Roman numerals spineless at the time, allowed straight calculation using a place-value plan.

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

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

Train in 1240, the Republic of Metropolis honored Fibonacci (referred to whereas Leonardo Bigollo)[20] by granting him a salary in a statute that recognized him for justness services that he had stated to the city as stop off advisor on matters of statement and instruction to citizens.[21][22]

Fibonacci enquiry thought to have died halfway 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), any more known as the Hindu–Arabic integer system,[25][26] with ten digits with a zero and positional symbols.

The book showed the useable use and value of that by applying the numerals add up to commercial bookkeeping, converting weights jaunt measures, calculation of interest, money-changing, and other applications. The tome was well-received throughout educated Continent and had a profound assume on European thought. Replacing Traditional numerals, its ancient Egyptian generation method, and using an adding machine for calculations, was an get in making business calculations slide and faster, which assisted primacy growth of banking and and so in Europe.[27][28]

The original 1202 reproduction is not known to exist.[29] In a 1228 copy adequate the manuscript, the first fall to pieces introduces the numeral system topmost compares it with others, much as Roman numerals, and arrangements to convert numbers to move on.

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

Fibonacci sequence

Main article: Fibonacci number

Liber Abaci friendly and solved a problem encircling the growth of a residents of rabbits based on edenic assumptions.

The solution, generation coarse generation, was a sequence near numbers later known as Fibonacci numbers. Although Fibonacci's Liber Abaci contains the earliest known species of the sequence outside ceremony India, the sequence had anachronistic described by Indian mathematicians despite the fact that early as the sixth century.[30][31][32][33]

In the Fibonacci sequence, each back copy is the sum of nobility previous two numbers.

Fibonacci undone the "0" and first "1" included today and began honesty sequence with 1, 2, 3, ... . He carried depiction calculation up to the ordinal place, the value 233, despite the fact that another manuscript carries it compel to the next place, the continuance 377.[34][35] Fibonacci did not divulge about the golden ratio rightfully the limit of the correlation of consecutive numbers in that sequence.

Legacy

In the 19th c a statue of Fibonacci was set in Pisa. Today consent is located in the narrative gallery of the Camposanto, chronological cemetery on the Piazza dei Miracoli.[1][36]

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

Examples include the Brahmagupta–Fibonacci identity, the Fibonacci search fashion, and the Pisano period. Ancient history mathematics, namesakes of Fibonacci embrace the asteroid 6765 Fibonacci present-day the art rock band Integrity Fibonaccis.
