**We often wonder what the golden ratio is. From our DNA to the Greek Parthenon. It is about the perfect proportion found all around us. Let's see what the Golden ratio is.**

Throughout history, many questions have been asked. The notion of the golden ratio was explored by many famous philosophers, architects, painters. For them, it was the perfect proportion to be found in their works. 
Throughout the citabe human history, the golden ratio has attracted the attention of all artists. Through observation of the forms in nature, man realized that there are certain regular parts that are in a natural, perfect relationship, ie. proportions.  The great Leonardo da Vinci talked about a **"golden ratio"** and the cross section that separates the whole into ideal parts is the **"golden cross section"**.  The golden section is the most perfect proportion of growing shapes in nature, its ratio is obtained by dividing one lengthwise so that the ratio of the larger part to the whole is the same as the ratio of the smaller part to the larger one. This ratio is exactly 0.6180339887 and its designation is the Greek letter Phi.

The golden section has the greatest importance in mathematics in the famous **Fibonacci sequence**. When each number is divided by the following number from the Fibonacci sequence we get approximately 0.618. When the number is divided by the one in front then we get 1.618. The Fibonacci sequence was discovered by Leonardo of Pisa, called Fibonacci. In his work *Liber abaci*, he came up with a specific sequence in which each successive number corresponds to the sum of the two previous ones. That string is 1, 2, 3, 5, 8, 13, 21...

Until the 19th century, the gold section and the Fibonacci sequence were only observed through mathematical and geometric problems. Then a German scientist investigated the emergence of these two phenomena in nature and art. He came to the conclusion that individual plants, anatomy as well as classic sculptures were made in gold. He also laid out the theory that the entire universe was built in accordance with these proportions.
