The Fibonacci sequence is a series of numbers founded by a mathematician named Leonardo Pisano. A number is started by adding up the two numbers before it, starting with 0 and 1. A Fibonacci spiral is associated with many forms of art and nature. The spiral is drawn inside, through the center of squares proportioned with Fibonacci numbers.
The Golden mean/ratio is a number of approximately 1.618 and is represented by the Greek letter “phi.”
The two have a special relationship in that if you take two successive numbers from the Fibonacci sequence, their ratio is very close to the golden ratio. The bigger the pair of numbers, the more approximate the ratio is.
