*Learning is the gate, not the house.*

When you see it, don’t think it's the house,

you must pass through it to enter the house that lies beyond.

Since learning is a gate, when you read books don’t think this is the Method.

The misunderstanding caused many people to remain ignorant on the Method,

as much as they studied and as many words they knew.

(Yagyu Munenori)

During his long residence in Algiers, where his father was a custom employee, he was able to learn the Arabic numerals and, later, traveling throughout the Mediterranean countries, to learn the works of Euclid and Arab mathematicians.

His most important works are “Practica Geometrica” and “Liber Abbaci”, where he introduces the properties of the numbers sequence called Fibonacci. Some chronicles emphasize that he returned from a trip to Egypt with a mysterious series of numbers he developed after researching rabbits breeding rate.

The progression is described in Chapter XII of the book Liber Abbaci; in other words, the book is an abacus, a "guide book for numerals", written by Fibonacci in 1228. In this book, he ponders on the reproduction rate of rabbits, determining the solution and thus also the famous series.

His numbers and its sequences are also used in the technical analysis and, in particular, in Elliott’s theory.

Some analysts linked the extent and duration of the stock price movements with the Fibonacci numbers, developing graphical tools which take in consideration both price and time.

- Fibonacci was a trader, although he never did any trading at all.
