Nothing of this is true! New Agers make gross approximations to several logarithmic spirals in order to fit them to the number phi and the golden rule.DuncanM said:I don't know if there are any "practical uses" for Phi, it simply seems to come up quite often in nature and has several unique properties (for example, the arrangement of flower petals, seeds, the Great Pyramid of Giza, etc.).
There is much material posted on the following website:

This would give you a good start. If you do a search for "phi" or "golden section" you will find much more.

The number Phi, also known as the golden ratio, is approximately equal to 1.618. It is a mathematical constant that has been studied for centuries and is found in various natural and man-made structures. It is considered significant because of its aesthetic appeal and its presence in many aspects of life, from art and architecture to biology and physics.
The number Phi can be calculated by dividing a line into two unequal segments, with the longer segment being to the shorter segment as the entire line is to the longer segment. This ratio of approximately 1.618 is Phi.
Yes, the number Phi has been used in various practical applications, such as in design and architecture to create aesthetically pleasing proportions. It has also been studied in physics and biology for its presence in natural phenomena. However, its practical applications are still being explored and debated.
The number Phi can be found in various natural structures, such as the spiral patterns of seashells and the branching of trees. It is also present in the proportions of the human body, from the length of our fingers to the placement of our facial features.
The number Phi is closely related to the Fibonacci sequence, which is a series of numbers where each number is the sum of the two preceding numbers. As the sequence progresses, the ratio between two consecutive numbers approaches Phi. This relationship is seen in many natural structures, such as the spiral patterns of sunflowers and pinecones.
