Who was Fibonacci? Also known as Fibonacci, Leonardo of Pisa was an Italian mathematician who spread the Hindu-Arabic numeral system as well he was/is known for a sequence of numbers called the Fibonacci numbers. Leonardo of Pisa was born around the year 1170 and died at an estimated 1240 or 1250, as the date of his death isn’t actually known. Fibonacci’s contributions to the world of mathematics seem rather immense with him being the one to introduce and popularize the Modus Indorum, which when translated means “method of the Indians”. The Modus Indorum today is known as the Arabic numeral system. The way this system was popularized by Fibonacci was in a book he wrote in the year 1202 called Liber Abaci. In the Liber Abaci Fibonacci used the Arabic numeral system and demonstrated its importance relating to things like the conversion of weights and measurements, calculating interest, commercial bookkeeping and many other practical uses. Also in the Liber Abaci was the Fibonacci number sequence, also known as the Fibonacci numbers. This number sequence was originally based on the growth rate of a population of rabbits. This number sequence was already known by mathematicians in India in the 6th century, but it was Fibonacci’s Liber Abaci that introduced this to the western world. The Fibonacci number sequence is ordered by each number being the sum of the previous two numbers. Here are two examples of the golden ratio. The first is present in nature and demonstrates the golden ratio in terms of the ideal and most efficient way to form a spiral. This is called the golden spiral and is present in many other ways in nature; such as snail shells, pine cones, a human ear and a tonne of others. The second example is also of the golden spiral but is man-made. The golden ratio is used in art as well as architecture for the
