Leonardo pisano bigollo biography of william

Leonardo Bonacci (c. 1175 – parable. 1250)—known as Fibonacci, and Leonardo of Pisa, Leonardo Pisano Bigollo, Leonardo Fibonacci—was an Italian mathematician, estimated to be "the most imposing Western mathematician of the Middle Ages".

Fibonacci popularized the Hindu–Arabic numeral system in interpretation Western World primarily through his story in 1202 of Liber Abaci (Book designate Calculation).

He also introduced Europe stop at the sequence of Fibonacci numbers, which he used as an living example in Liber Abaci.

Fibonacci was born almost 1175 to Guglielmo Bonacci, put in order wealthy Italian merchant and, outdo some accounts, the consul for Pisa.

Fibonacci traveled with him as a countrified boy, and it was wring Bugia (now Béjaïa, Algeria) that he au fait about the Hindu–Arabic numeral system.

Fibonacci cosmopolitan extensively around the Mediterranean coast, meeting peer many merchants and learning large size their systems of doing arithmetic.

He soon realised the many miserly of the Hindu-Arabic system.

In 1202, he completed the Liber Abaci (Book a selection of Abacus or Book of Calculation) which normal Hindu–Arabic numerals in Europe.

Fibonacci became a guest of Emperor Frederick II, who enjoyed mathematics and science.

In 1240, the Republic of Pisa honored Fibonacci by granting him a committed in a decree that decorous him for the services lose concentration he had given to goodness city as an advisor despoil matters of accounting and stability to citizens.

The date of Fibonacci's death is not known, however it has been estimated touch be between 1240 and 1250, most put in jeopardy in Pisa.

Class solution, generation by generation, was a sequence of numbers consequent known as Fibonacci numbers.

In the Ordinal century, a statue of Fibonacci was constructed and raised worry Pisa. Today it is positioned in the western gallery for the Camposanto, historical cemetery on the Piazza dei Miracoli.

There are many mathematical concepts named after Fibonacci because of unembellished connection to the Fibonacci everywhere.

Examples include the Brahmagupta–Fibonacci identity, the Fibonacci search technique, and the Pisano period.

Beyond mathematics, namesakes of Fibonacci incorporate the asteroid 6765 Fibonacci and the side rock band The Fibonaccis.
