It is called sacred geometry to the set of geometric shapes that can be observed in the design of places that are considered sacred and these forms are given symbolic and in some cases esoteric meanings. At the base of this sacred geometry that we find in the construction of buildings such as cathedrals, churches or mosques are the golden number, that is φ (Phi), and the Golden Spiral . Join us to know 15 curiosities of these elements of sacred geometry.
Of the golden number, the golden ratio or the golden spiral they can talk to you people who work in very different fields. For artists it is a geometric way to use space in painting, a biologist will tell you that it is the basis of the beauty of nature, a doctor could explain to you that it is present in the human body and a mathematician who is the solution to infinity of geometric and algebraic problems. All of them are right. If you want to know the exact proportions and formulas of the Golden Spiral you can find them here .
15 curiosities of the Golden Spiral and the Golden Number
1. For geometry, a golden spiral is that logarithmic spiral whose growth factor is φ (Phi). This spiral widens, that is to say, it moves away from its origin, in a factor of Phi for each quarter of rotation it effects.
2. A Phi is known as Golden Ratio or Golden Number. It should not be confused with the number π (pi) we study at school. φ e It's an irrational number with a value = 1.6180339887498948482 ...
3. The first to formally study the golden number was the Greek mathematician and geometer Euclides.
4. The golden number was called Phi in honor of the Greek sculptor Phidias as proposed by the engineer and inventor Mark Barr in 1909.
5. There are other spirals very similar to the Golden spiral like Fibonacci. Both, although different, are based on the growth factor Phi, the Golden Number.
6. Leonardo of Pisa also known as Fibonacci was an Italian mathematician who lived in Pisa between 1170 and 1240. He was the first European to describe the numerical sequence that bears his name.
7. The Fibonacci sequence is a list of numbers in which anyone can find the next by adding the last two. The first figures are: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ... If a number is divided from this list by the previous one, the result of this operation is getting closer and closer to the golden ratio.
8. The golden spiral It is present in many figures of nature such as galaxies or plants and we also find it in art.
9. A special aesthetic character is attributed to all those objects whose measures keep the "golden ratio" and in some groups throughout history, in addition, it was assigned a mystical value.
10. Some authors claim that in Leonardo da Vinci's Gioconda you can find a Golden Spiral .
11. According to experts, the Great Pyramid of Giza and the Parthenon they follow the golden ratio.
12. DNA molecules also follow this logarithmic spiral.
13. The shells of nautilus and other molluscs present a logarithmic spiral that really comes closer to the Fibonacci spiral than to the golden spiral itself. This design allows them to grow without changing shape.
14. Many people have a hobby to find the golden ratio in nature.
15. Here are several examples of golden spiral or Fibonacci spiral In nature:
This is the spiral that we can observe in a nautilus shell.
Hurricanes also have their particular golden spiral .
Spiral galaxies follow the Fibonacci spiral.
Finally, here is one of those logarithmic spirals on the button of a chamomile flower.
Did you realize that the Spiral Aurea Is it present in this way in our environment and even in our own bodies? Have you "hunted" the golden ratio in some element of your daily life? Share it with us! If you have been interested in this article, you may want to meet one of the most important maths women and, interestingly enough, the daughter of English poet Lord Bayron: Ada Lovelace, the lovely number .
