"The Golden Mean is represented by the Greek letter phi, (with the decimal representation of 1.6180...) is one of those mysterious natural numbers that seems to arise out of the basic structure of our cosmos. Phi appears regularly in the realm of things that grow and unfold in steps just as the Nautilus shell grows larger on each spiral by phi."
Sacred geometry of shells. The Golden Mean is represented by the Greek letter phi 1.6180... It is one of those mysterious natural numbers - basic building blocks - that define the basic structure of our cosmos.
The Mathematics of Beauty The Fibonacci Sequence is a sequence of numbers where each number is the sum of the previous two—i.e., 0, 1, 1, 2, 3, 5, 8, 13, 21, 34…and so on to infinity. The ratio of one number to the next is approximately 1.61803, which is called “phi”, or the Golden Ratio. It’s not a magical mathematical equation of the universe, but it definitely reflects natural, aesthetically beautiful patterns.
