# The Fibonacci Sequence: Origin

Azmin Azran

The Fibonacci sequence is one of the simplest, yet fascinating mathematical discoveries ever made. Back in the beginning of the thirteenth century, this crazy talented guy from Pisa, Italy called Leonardo Pisano Bogollo, later known as Fibonacci, presented his discoveries in his book “Liber Abaci”. Fibonacci is famous for introducing a new numeral system in Europe, the Hindu-Arabic system that replaced the Roman numeral system; the latter was more complicated and limited in applications. The Fibonacci sequence was only one of his many great contributions in the field of mathematics.
What is the Fibonacci sequence? It is a sequence of integers, or whole numbers where every number is the sum of the previous two. The sequence begins with 0, 1 or 1, 1 as the first two integers and after that every number is the sum of the last two. By definition, the sequence will look something like this:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89…….. or 1, 1, 2, 3, 5, 8, 13, 21, 55, 89, 144………………

Although this sequence was named after Fibonacci, it was not he who first discovered it. This sequence has been seen appearing in Sanskrit scripts from as early as the 6th century. But Fibonacci is given credit for being able to bring it to light among Western mathematicians. And since then, Western mathematicians have observed many of its fascinating applications.
