PINEAPPLE #17

======================================================

PINEAPPLE & THE MATHEMATICAL FIBONACCI NUMBERS

 

Pineapple scales or fruitlets or eyes are patterned into spirals.

Since these scales/fruitlets/eyes are approximately hexagonal in shape, three (3) distinct sets of spirals can be seen on the surface of a mature Pineapple.

 

One set of 5 parallel spirals ascends at a shallow angle to the right,

A second set of 8 parallel spirals ascends more steeply to the left,

and

A third set of 13 parallel spirals ascends very steeply to the right.

 

The numbers 1, 2, 3, 5, 8, 13, 21, 34 etc. are called Fibonacci Numbers where a Fibonacci number is the sum total of the previous 2 Fibonacci Numbers.
