# Pi and Phi: beautiful mysteries of the Universe

The history of the world is full of mysteries and studies. Astrology, numerology, nature and mathematicians studies, such as **Pi and Phi**. Brilliant minds have dedicated themselves in the past to unraveling these puzzles in the eyes of all. Thanks to this today we have a better understanding of what is happening around us. In this article, we will delve into one of the most interesting subjects ever.

## Pi and Phi: the history in time

At school, we all learn about the number Pi. It is the most famous irrational number in the history of mathematics, equivalent to 3,14. This is the constant ratio between the perimeter of any circumference and its diameter.

On the other hand, another famous irrational number (and with a similar name) carries many more mysteries and enigmas in its history. The Phi number, or gold number, is equivalent to 1,618 and appears in a multitude of elements of nature. This is why it is also called Divine Proportion or Golden Ratio.

From the beginnings of humanity, ideal proportions and perfect beauty were sought after. The Greeks then discovered the so-called golden rectangle. From the division of the greater side by the smaller side, they reached a proportion. And they built everything using it. The Parthenon and all the architectural works of the time obeyed the ratio of 1,618.

The Egyptians also adhered to this “commandment” and did the same with their pyramids. Each stone of a row was 1,618 smaller than the stones of the bottom row and so on.

### Phi and Leonardo Fibonacci

The divine proportion dictated classical architecture for long years. Until in 1200, a mathematician named Leonardo Fibonacci discovered something very interesting. In studying the growth of rabbit populations, he observed that the average growth rate was equal to 1,618. That is, the Phi number.

The calculations varied a little up and down, but the average was exactly the same as the ratio used by the Greeks and Egyptians. From there, the sequence of calculations that led to this discovery became known as the Fibonacci Sequence.

But although the sequence has become the most famous mathematical sequence and tied to the name of Fibonacci, researchers have found other older studies. The mathematician Pythagoras was already studying and talking about it. However, it was Fibonacci who systematized and recorded the study, even publishing a book called “Liber Abaci”.

### Phi and the Solar System

The most surprising of all is that this ratio is not only found on planet Earth. Astronomers can observe it in galaxies, in the way the smaller stars are distributed around a main star. The stars always arrange in a spiral, following a proportion of guess what? 1,618, of course.

The measurements and distance between the Earth and the Moon form a triangle that results 1,618. Saturn also presents the divine proportion with its rings. This leads us to think that coincidences do not really exist. The Universe might just be the most perfect system that exists. Everything is connected.

**Tesla and the numbers**

Nikola Tesla was an electrical engineer who also noted the beauty of numbers and their relation to the Universe. He used to say that mathematics was not invented by humans, just discovered. After all, there is no shortage of evidence that it has always existed.

From these numerical patterns already existing in the Universe, he found a fundamental system of nature. He was obsessed with numbers 3, 6 and 9 because he believed that the universal language of mathematics was related to those numbers.

Some researchers believe that this language discovered by Tesla may be the key to access the third or fourth dimension. We would enter an energy vortex and discover the free energy.

When we read and learn about all this, it is when we remember how little we are in comparison to everything we know. And you can be sure that there is a lot more that is beyond our awareness, understanding or that has not yet been discovered. What remains for us is to marvel and be humble before the vastness and infinity of the wonderful Universe.
