The golden ratio is the name of the harmony between the parts or stages that constitute a whole, which can be seen in our daily life, in nature or in the universe, any time or place.
The Golden Ratio, which we can call the most beautiful harmony of the parts that make up a whole as we mentioned before, is the string of numbers starting with 1.61803389. The symbol of the Golden Ratio is Phi,Φ.
For example, if we divide the black line into two parts according to the Golden Ratio, the ratio of red part to the blue and the ratio of the blue part to the black is equal.
The Fibonacci string or Fibonacci numbers emerged after Leonardo of Pisa asked the following problem in his book Liber Abaci, in which he described the Indian-Arab numbers. You can learn more about Leonardo Fibonacci from this page.
The problem asks this question,
Put a pair of rabbits in a room with all sides surrounded by walls. How many pairs of rabbits are there at the end of the year if every pair of rabbits give birth to a new pair every month, (but the newborn rabbit pair will start giving birth from the second month)?
The resulting number sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34, 55,
If you ask what these numbers mean let us tell you, that it was noticed later that when these numbers are divided by each other the number 1,618033… is the result which is widely used in nature and many places in the universe.
But it would be wrong to say that it is used everywhere or continuously because it is just one of the ratios that we have discovered so far. There are writings about the human body describing that as the harmony of the combined particles come closer to the Golden Ratio they approach the average.
The most common examples are plants’ petals, sunflowers, cones, aloe plants and similar plants. As you can see below, some tree branches produce new branches similar to the Fibonacci number sequence.
We come across the gold ratio many times on our bodies. For example, our belly-button is situated at a golden ratio in relation to our height. If we divide our arms from our elbows, we come across the golden ratio. The golden ratio can be found in the human fingers or the face.
It is important to note that the body of each individual shows different proportions, but if we look at the average in general we see that we are closer to the Golden Ratio.
Nautilus shells living in the deep waters of the South Pacific are a perfect example of the Golden Ratio. In addition to this, there are examples of the golden ratio in starfish, dolphins, honey bees and ants.
The spiral arms of the Milky Way Galaxy, where our solar system is located, are a good example of the Golden Ratio. We also come across this ratio in storms and whirlpools. Below you can see a satellite picture of Hurricane Sandy which hit the continent of America in 2012.
Brands such as Toyota, Mercedes, Twitter, Apple, Google, Pepsi have benefited from the ideal Golden Ratio when designing their logos.
