Having done a less than ideal job of explaining Fibonacci numbers during the last reveal, I will try again.
These are the first few numbers of the Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34..... You get a Fibonacci number by adding together the two numbers that came before it. For example, in the little sequence above, you would add 21+34 together to get 55 which is the next number in the sequence, and so on out into infinity.
Fibonacci numbers are everywhere -in nature, in architecture, in the human body, but I was quite surprised to find the following headline in the Smithsonian Magazine (I don't take a newspaper, so a magazine had to do.) Anyway, the headline I used for this quarter's challenge is The Fibonacci sequence is Everywhere -Even the Troubled Stock Market. It is subtitled: The curious set of numbers shows up in nature and also in human activities.
I came upon the sequence when I was looking for a pleasing pattern to make a striped crochet afghan; but it shows up in human activity, too?! Groovy.
