Working Money: Those Ubiquitous Fibonacci Ratios by Rudy Teseo

Working Money: Those Ubiquitous Fibonacci Ratios by Rudy Teseo How do I use thee? Let me count the ways. What do nature, astronomy, and the stock market have in common? They have something in common you may have heard of, but never really known what it is: a number sequence discovered by a 13th-century mathematician named Leonardo of Pisa and spelled out in his work Liber Abacci. I doubt that he ever considered the sequence, later known as the Fibonacci series — zero, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, and so on — would have the long-lasting effect it did, eventually finding its way into fields he could not have even dreamed of, like stock market analysis and computer programs. But that’s exactly what happened.
