What be this Fibonacci? May 19 2017

First of all, Fibonacci is a who.   

He was an Italian mathematician.   Perhaps the most highly regarded of the Middle Ages.

(b. 1170 -  d.1250)

 

Why are you hearing about him here?

Because the Fibonacci Sequence  is used by many quilters  to help determine block or border size relationships. In this sequence of numbers, each number is the sum of the previous 2 numbers. (In other words: 1,1,2,3,5,8,13,21,34,55,89,144,233, etc.)

It is also known as the "Golden Ratio".   This next picture is a Fibonacci Spiral based on the Golden Ratio.

 Which next becomes this...

Let's put the Golden Ratio into something more "Quilty".

I'm with you.   That's enough for today.

Later gators!
