## Fibonacci

In maths, the Fibonacci numbers or Fibonacci sequence are any numbers that follow the following rule:

Any number is the sum of the 2 preceding numbers.

So for example, 1,1,2,3,5,8,13,21,34,55,89,144 etc.

The Fibonacci is named after Leonardo Fibonacci, who wrote a book in 1202 detailing this sequence. Actually, this sequence had been recorded in an Indian work ealrier, so Fibonacci was the mathematician to first reveal it to Western Civilization.

Many shapes in the natural world can be described with a Fibonacci system- it's one of those "natural mysteries". So, for example, the branching in trees, the shape of a nautilus shell, and the dimensions of a pine cone can all be described with this sequence.

Fibonacci (also known as Leonardo of Pisa) wrote his book Liber Abaci in 1202, using as his example a population of rabbits.
