Happy Fibonacci Day!

The calendar listing funny, weird and wonderful holidays tells me today, November 23rd, is the birthday of Leonardo Fibonacci.  Who is Fibonacci?  

   Some scholars refer to him as the greatest European mathematician of the Middle Ages.  I must admit I did not learn about Fibonacci in an advanced math class.....I learned about him in Ravelry!  More about that in a minute...

Leonardo is famous for discovering the Fibonacci "Sequence of Numbers".  This number sequence often appears in nature and also appears in music, art and fashion design.  The numbers in this sequence are characterized by the fact that every number after the first two is the sum of the two preceding numbers.  An example:

                            0, 1 ,2, 3, 5, 8, 13, 21, 34 ,55 ,89, 144....

This sequence can begin with any number and go on indefinitely. Each number is the sum of the two preceeding numbers.   Anyone with fundamental arithmetic skills can begin and complete this sequence for a stripe pattern.  When the numbers are made into a spiral, you will see them in nature in pinecones, daisies, etc.  You will see that spiral in many works of art.

In the beginning of my post, I told you I learned about Fibonacci in Ravelry.  It happened like this: I searched  for a felted bag made of several colors of yarn and found "It Felt Random Bag"         it felt random bag.jpgThe pattern refers the reader to a link for "The Random Stripe Generator". This app has you input your colors and the allowed width of stripes and creates a simulation of what your finished product will look like.  This can be used to create stripe patterns for scarves, blankets, shawls, quilts, etc.  That led me to The Fibonacci Sequence which provides a very easy mathematical way to design
a striping pattern.  Here is the link if you want to play.  http://www.biscuitsandjam.com/stripe_maker.php



How to celebrate Fibonacci Day?   We suggest  this is the day to dig out yarns of different colors and design yourself a new scarf, shawl or blanket using the Fibonacci Sequence.   You will be surprised how easy it is to create your own designs with this mathematical twist! Or, if you would like a preview of your project, go to the "Random Stripe Generator" on Google.  Do you just want to see some knit designs?  Search for Fibonacci in Ravelry.

Have a wonderfully "stripey" experience.  Happy Fibonacci Day!
