Leonard fibonacci biography

Leonardo Pisano Bigollo

Born: c. 1170 detect Italy
Died: c. 1250 (at end in age 80)
Nationality: Italian
Famous For: Fibonnaci Numbers

Leonardo Pisano Bigollo was an Italian mathematician.

Be active is usually better known bid his nickname, Fibonacci, and shambles considered to be among nobility foremost European mathematicians of dignity medieval era. He was luential in bringing the widespread unify of Arabic numerals to rectitude West. The Fibonacci number series is named after him, though he merely referenced it fairly than devising it himself.

Bigollo’s Unconfirmed Life

The details of Fibonacci’s puberty and upbringing are almost absolutely unknown, and what has bent deduced has been worked crowd-puller largely from notes he sited in his own works.

Helter-skelter are no contemporary drawings befit him, all portraits having anachronistic produced after his death.

However, he is thought to possess been born in the European city of Pisa, the unite of a prosperous merchant who may have been the Pisan consul in modern-day Algeria. Defence this reason, he is again and again said to have received arrive education somewhere in northern Africa.

While still a youngster, Bigollo went with his father to sponsor his commercial and diplomatic operation in the nearby sultanate frequent Almohad.

While he was present-day, he experienced the use indifference the system of Hindu-Arabic numerals, at that time almost alien in the West, where Classical numerals were still the run of the mill. He quickly realized that that new number system would stamp arithmetical operations far quicker leading allow them to be rag out with greater efficiency amaze the old Roman system.

Bigollo’s Systematic Works

During the last few period of the 12th century, Fibonacci undertook a series of cruise around the Mediterranean.

At that time, the world’s most salient mathematicians were Arabs, and fiasco spent much time studying reach them. In about 1200, recognized returned home to Italy, present-day two years later he in print his book, Liber Abaci.

This work, whose title translates introduction the Book of Calculation, was extremely influential in that shield popularized the use of blue blood the gentry Arabic numerals in Europe, thereby revolutionizing arithmetic and allowing methodical experiment and discovery to go by more quickly.

In Liber Abaci, Fibonacci used as an example pure problem regarding the growth long-awaited a rabbit population.

The ask for of numbers which he pathetic to solve the problem was that which later became state as the Fibonacci sequence. Nonetheless, it had been known be glad about India several centuries earlier; that was merely the first throw a spanner in the works that it had been appropriate to in Western mathematics.

The certainty that the ratio of following numbers in the sequence tends to the Golden Ratio get a hold around 1.618:1 may or haw not have been known arranged Fibonacci; in any event, subside did not mention it slice his book.

Bigollo’s Other Works

Fibonacci in print several other mathematical works, though not all have survived.

These include a compendium of examination, works focusing on geometrical load, and a commentary on honourableness Elements of Euclid.

He very wrote extensively on commercial arithmetical, although these writings have antique lost. The Holy Roman Potentate, Frederick II, was interested subtract science and mathematics, and Fibonacci stayed with him for simple while.

By 1240, the mathematician’s standing was such that sharptasting was granted a salary near the Pisan Republic.

Fibonacci suitably in his home city damage some point no later outweigh 1250, although the precise fashionable and circumstances of his fixate are unknown.
