Fibonacci and the Golden Ratio. The relationship between the Fibonacci Sequence and the Golden Ratio is a surprising one. We have two seemingly unrelated topics producing the same exact number. Considering that this number (or Golden Ratio) is non-rational, the occurence is beyond coincidence.
Some of the greatest mathematical minds of all ages, from Pythagoras and Euclid in ancient Greece through the medieval Italian mathematician Leonardo of Pisa and the Renaissance astronomer Johannes Kepler, to present-day scientific figures such as Oxford physicist Roger Penrose have spent endless hours over this simple ratio and its properties. ... Biologists, artists, musicians, historians, architects, psychologists, and even mystics have pondered and debated the basis of its ubiquity and appeal. In fact, it is probably fair to say that the Golden Ratio has inspired thinkers of all disciplines like no other number in the history of mathematics.
Can be also worn as a very large pendant but we sell the chain separately.
