Those
Fascinating Fibonaccis! 
Patterns
in numbers have intrigued mathematicians for years. Early in the
thirteenth century, Leonardo Fibonacci (feebuhnah'chee) discovered a
fascinating sequence of numbers.
These
much studied Fibonacci numbers retain their magic and mystery to this
day and are ubiquitous in both natural and manufactured products—pine
cones and pineapples, poetry and computers, art and music, the heavens
and the sea—and in the numerical patterns within the sequence itself. The Fibonacci sequence is a prime example of how mathematics
seemingly unrelated things.
Try
this! Start with a pair
of rabbits (one female, one male) born on 1 January. Assume that all
months are of equal length and that—
 Rabbits
begin to produce young two months after their own birth;
 After
reaching the age of two months, each pair produces a mixed pair
(one female, one male) and then another mixed pair each month
thereafter; and

Fibonacci
asked, “How many pairs of rabbits will there be after one year?”

Fibonacci Numbers in
Nature 
Fibonacci
numbers abound in nature.
Cutting a bell pepper crosswise reveals 3 chambers.
An apple has a 5 pointstar crosssection, and a lemon has an
8chambered cross section.
A daisy almost always has 13, 21, or 34 petals.
Sunflowers adore Fibonacci numbers!
Their seeds spiral out from the center with 21 spirals in the one
direction and 34 n the other.
The giant sunflower has 89 and 144 spirals, and the whopper
sunflower has 144 and 233 spirals.
Each set of spirals contains adjacent Fibonacci numbers.
The
genealogy of a drone, a male bee, follows the Fibonacci sequence.
A drone comes from an unfertilized egg; it has a mother but no
father.
A female bee has both a mother and a father. Can you figure
out the sequence?
