Leonardo
of Pisa, better known as Fibonacci, was born in
Pisa, Italy, about 1175 AD. He was known as the
greatest mathematician of the middle ages.
Completed in 1202, Fibonacci wrote a book
titled Liber abaci on how to do
arithmetic in the decimal system. Although
it was Fibonacci himself that discovered the
sequence of numbers, it was French mathematician,
Edouard Lucas who gave the actual name of "Fibonacci
numbers" to the series of numbers that was
first mentioned by Fibonacci in his book.
Since this discovery, it has been shown that
Fibonacci numbers can be seen in a variety of
things today.
By charting the population of
rabbits, Fibonacci discovered a number series from
which one can derive the Golden Mean. The
beginning of the sequence: 0, 1, 1, 2, 3, 5, 8,
13, 21, 34, 55... Each number is the sum of the
two preceding numbers. Dividing each number in the
series by the one which precedes it produces a
ratio which stabilizes around 1.618034.
