Story about Fibonacci Numbers

Posted on: September 30, 2015

Watching the CBBC drama Leonardo with my girls. In 2nd episode of the first series, “Da Vinci’s Code”, Leonardo’s notebook was stolen by Lorenzo de Medici’s father, Piero de Medici. But it proves to be no use to him because all the formulae and calculations are written in code. Piero employs Lorenzo’s maths teacher Professor Pico to decipher the code and guess what, Fibonacci sequence were used by Leonardo to trick this professor.

It reminded me to share this story I learnt about the person who introduced this famous numbers, Leonardo of Pisa.

He was one of the greatest Western mathematicians of the Middle Ages. His greatest contribution included the introduction of the Hindu-Arabic numerals 0 to 9 to Western Europe in place of Roman Numerals (I, II, III, IV, V, etc). His book, Liber Abaci or also knows as Book of Calculations, documented the Hindu-Arabic numerals and how the Hindu-Arabic numerals could be useful in business transactions.

He also generated the famous Fibonacci numbers whereby in each term, after the first two terms, is the sum of the two preceding terms.
