Golden ratio in the human body. The human body and the golden ratio

This harmony is striking in its scale...

Hello, friends!

Have you heard anything about Divine Harmony or the Golden Ratio? Have you ever thought about why something seems ideal and beautiful to us, but something repels us?

If not, then you have successfully come to this article, because in it we will discuss the golden ratio, find out what it is, what it looks like in nature and in humans. Let's talk about its principles, find out what the Fibonacci series is and much more, including the concept of the golden rectangle and the golden spiral.

Yes, the article has a lot of images, formulas, after all, the golden ratio is also mathematics. But everything is described in fairly simple language, clearly. And at the end of the article, you will find out why everyone loves cats so much =)

What is the golden ratio?

To put it simply, the golden ratio is a certain rule of proportion that creates harmony?. That is, if we do not violate the rules of these proportions, then we get a very harmonious composition.

The most comprehensive definition of the golden ratio states that the smaller part is related to the larger one, as the larger part is to the whole.

But besides this, the golden ratio is mathematics: it has a specific formula and a specific number. Many mathematicians, in general, consider it the formula of divine harmony, and call it “asymmetrical symmetry”.

The golden ratio has reached our contemporaries since the times of Ancient Greece, however, there is an opinion that the Greeks themselves had already spied the golden ratio among the Egyptians. Because many works of art of Ancient Egypt are clearly built according to the canons of this proportion.

It is believed that Pythagoras was the first to introduce the concept of the golden ratio. The works of Euclid have survived to this day (he used the golden ratio to build regular pentagons, which is why such a pentagon is called “golden”), and the number of the golden ratio is named after the ancient Greek architect Phidias. That is, this is our number “phi” (denoted by the Greek letter φ), and it is equal to 1.6180339887498948482... Naturally, this value is rounded: φ = 1.618 or φ = 1.62, and in percentage terms the golden ratio looks like 62% and 38%.

What is unique about this proportion (and believe me, it exists)? Let's first try to figure it out using an example of a segment. So, we take a segment and divide it into unequal parts in such a way that its smaller part relates to the larger one, as the larger part relates to the whole. I understand, it’s not very clear yet what’s what, I’ll try to illustrate it more clearly using the example of segments:

So, we take a segment and divide it into two others, so that the smaller segment a relates to the larger segment b, just as the segment b relates to the whole, that is, the entire line (a + b). Mathematically it looks like this:

This rule works indefinitely; you can divide segments as long as you like. And, see how simple it is. The main thing is to understand once and that’s it.

But now let’s look at a more complex example, which comes across very often, since the golden ratio is also represented in the form of a golden rectangle (the aspect ratio of which is φ = 1.62). This is a very interesting rectangle: if we “cut off” a square from it, we will again get a golden rectangle. And so on endlessly. See:

But mathematics would not be mathematics if it did not have formulas. So, friends, now it will “hurt” a little. I hid the solution to the golden ratio under a spoiler; there are a lot of formulas, but I don’t want to leave the article without them.

Fibonacci series and golden ratio

We continue to create and observe the magic of mathematics and the golden ratio. In the Middle Ages there was such a comrade - Fibonacci (or Fibonacci, they spell it differently everywhere). He loved mathematics and problems, he also had an interesting problem with the reproduction of rabbits =) But that’s not the point. He discovered a number sequence, the numbers in it are called “Fibonacci numbers”.

The sequence itself looks like this:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233... and so on ad infinitum.

In other words, the Fibonacci sequence is a sequence of numbers where each subsequent number is equal to the sum of the previous two.

What does the golden ratio have to do with it? You'll see now.

Fibonacci Spiral

To see and feel the whole connection between the Fibonacci number series and the golden ratio, you need to look at the formulas again.

In other words, from the 9th term of the Fibonacci sequence we begin to obtain the values ​​of the golden ratio. And if we visualize this whole picture, we will see how the Fibonacci sequence creates rectangles closer and closer to the golden rectangle. This is the connection.

Now let's talk about the Fibonacci spiral, it is also called the “golden spiral”.

The golden spiral is a logarithmic spiral whose growth coefficient is φ4, where φ is the golden ratio.

In general, from a mathematical point of view, the golden ratio is an ideal proportion. But this is just the beginning of her miracles. Almost the entire world is subject to the principles of the golden ratio; nature itself created this proportion. Even esotericists see numerical power in it. But we will definitely not talk about this in this article, so in order not to miss anything, you can subscribe to site updates.

Golden ratio in nature, man, art

Before we begin, I would like to clarify a number of inaccuracies. Firstly, the very definition of the golden ratio in this context is not entirely correct. The fact is that the very concept of “section” is a geometric term, always denoting a plane, but not a sequence of Fibonacci numbers.

And, secondly, the number series and the ratio of one to the other, of course, have been turned into a kind of stencil that can be applied to everything that seems suspicious, and one can be very happy when there are coincidences, but still, common sense should not be lost.

However, “everything was mixed up in our kingdom” and one became synonymous with the other. So, in general, the meaning is not lost from this. Now let's get down to business.

You will be surprised, but the golden ratio, or rather the proportions as close as possible to it, can be seen almost everywhere, even in the mirror. Don't believe me? Let's start with this.

You know, when I was learning to draw, they explained to us how easier it is to build a person’s face, his body, and so on. Everything must be calculated relative to something else.

Everything, absolutely everything is proportional: bones, our fingers, palms, distances on the face, the distance of outstretched arms in relation to the body, and so on. But even this is not all, the internal structure of our body, even this, is equal or almost equal to the golden section formula. Here are the distances and proportions:

from shoulders to crown to head size = 1:1.618

from the navel to the crown to the segment from the shoulders to the crown = 1:1.618

from navel to knees and from knees to feet = 1:1.618

from the chin to the extreme point of the upper lip and from it to the nose = 1:1.618

Isn't this amazing!? Harmony in its purest form, both inside and outside. And that is why, at some subconscious level, some people do not seem beautiful to us, even if they have a strong, toned body, velvety skin, beautiful hair, eyes, etc., and everything else. But, all the same, the slightest violation of the proportions of the body, and the appearance already slightly “hurts the eyes.”

In short, the more beautiful a person seems to us, the closer his proportions are to ideal. And this, by the way, can be attributed not only to the human body.

Golden ratio in nature and its phenomena

A classic example of the golden ratio in nature is the shell of the mollusk Nautilus pompilius and the ammonite. But this is not all, there are many more examples:

in the curls of the human ear we can see a golden spiral;

its same (or close to it) in the spirals along which galaxies twist;

and in the DNA molecule;

According to the Fibonacci series, the center of a sunflower is arranged, cones grow, the middle of flowers, a pineapple and many other fruits.

Friends, there are so many examples that I’ll just leave the video here (it’s just below) so as not to overload the article with text. Because if you dig into this topic, you can go deeper into the following jungle: even the ancient Greeks proved that the Universe and, in general, all space is planned according to the principle of the golden ratio.

You will be surprised, but these rules can be found even in sound. See:

The highest point of sound that causes pain and discomfort in our ears is 130 decibels.

We divide the proportion 130 by the golden ratio number φ = 1.62 and we get 80 decibels - the sound of a human scream.

We continue to divide proportionally and get, let’s say, the normal volume of human speech: 80 / φ = 50 decibels.

Well, the last sound that we get thanks to the formula is a pleasant whispering sound = 2.618.

Using this principle, it is possible to determine the optimal-comfortable, minimum and maximum numbers of temperature, pressure, and humidity. I haven’t tested it, and I don’t know how true this theory is, but you must agree, it sounds impressive.

One can read the highest beauty and harmony in absolutely everything living and non-living.

The main thing is not to get carried away with this, because if we want to see something in something, we will see it, even if it is not there. For example, I paid attention to the design of the PS4 and saw the golden ratio there =) However, this console is so cool that I wouldn’t be surprised if the designer really did something clever there.

Golden ratio in art

This is also a very large and extensive topic that is worth considering separately. Here I will just note a few basic points. The most remarkable thing is that many works of art and architectural masterpieces of antiquity (and not only) were made according to the principles of the golden ratio.

Egyptian and Mayan pyramids, Notre Dame de Paris, Greek Parthenon and so on.

In the musical works of Mozart, Chopin, Schubert, Bach and others.

In painting (this is clearly visible): all the most famous paintings by famous artists are made taking into account the rules of the golden ratio.

These principles can be found in Pushkin’s poems and in the bust of the beautiful Nefertiti.

Even now, the rules of the golden ratio are used, for example, in photography. Well, and of course, in all other arts, including cinematography and design.

Golden Fibonacci cats

And finally, about cats! Have you ever wondered why everyone loves cats so much? They've taken over the Internet! Cats are everywhere and it's wonderful =)

And the whole point is that cats are perfect! Don't believe me? Now I’ll prove it to you mathematically!

Do you see? The secret is revealed! Cats are ideal from the point of view of mathematics, nature and the Universe =)

*I'm kidding, of course. No, cats are really ideal) But no one has measured them mathematically, probably.

That's basically it, friends! We'll see you in the next articles. Good luck to you!

P.S. Images taken from medium.com.

The most comprehensive definition of the golden ratio states that the smaller part is related to the larger one, as the larger part is to the whole. Its approximate value is 1.6180339887. In a rounded percentage value, the proportions of the parts of the whole will correspond as 62% to 38%. This relationship operates in the forms of space and time. The ancients saw the golden ratio as a reflection of cosmic order, and Johannes Kepler called it one of the treasures of geometry. Modern science considers the golden ratio as “asymmetrical symmetry”, calling it in a broad sense a universal rule reflecting the structure and order of our world order.

Story

The ancient Egyptians had an idea about the golden proportions, they knew about them in Rus', but for the first time the golden ratio was scientifically explained by the monk Luca Pacioli in the book “Divine Proportion” (1509), illustrations for which were supposedly made by Leonardo da Vinci. Pacioli saw in the golden section the divine trinity: the small segment personified the Son, the large segment the Father, and the whole the Holy Spirit. The name of the Italian mathematician Leonardo Fibonacci is directly associated with the golden ratio rule. As a result of solving one of the problems, the scientist arrived at a sequence of numbers now known as Fibonacci series: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 etc. Kepler drew attention to the relationship of this sequence to the golden proportion: “It is arranged in such a way that the two lower terms of this never-ending proportion add up to the third term, and any two last terms, if added, give the next term, and the same proportion is maintained ad infinitum " Now the Fibonacci series is the arithmetic basis for calculating the proportions of the golden ratio in all its manifestations. Leonardo da Vinci also devoted a lot of time to studying the features of the golden ratio; most likely, the term itself belongs to him. His drawings of a stereometric body formed by regular pentagons prove that each of the rectangles obtained by section gives the aspect ratio in the golden division. Over time, the golden ratio rule became an academic routine, and only the philosopher Adolf Zeising gave it a second life in 1855. He brought the proportions of the golden section to the absolute, making them universal for all phenomena of the surrounding world. However, his “mathematical aesthetics” caused a lot of criticism.

Nature

Even without going into calculations, the golden ratio can be easily found in nature. So, the ratio of the tail and body of a lizard, the distances between the leaves on a branch fall under it, there is a golden ratio in the shape of an egg, if a conditional line is drawn through its widest part. The Belarusian scientist Eduard Soroko, who studied the forms of golden divisions in nature, noted that everything growing and striving to take its place in space is endowed with the proportions of the golden section. In his opinion, one of the most interesting forms is spiral twisting. Archimedes, paying attention to the spiral, derived an equation based on its shape, which is still used in technology. Goethe later noted nature’s attraction to spiral forms, calling the spiral the “curve of life.” Modern scientists have found that such manifestations of spiral forms in nature as a snail shell, the arrangement of sunflower seeds, spider web patterns, the movement of a hurricane, the structure of DNA and even the structure of galaxies contain the Fibonacci series.

Human

Fashion designers and clothing designers make all calculations based on the proportions of the golden ratio. Man is a universal form for testing the laws of the golden ratio. Of course, by nature, not all people have ideal proportions, which creates certain difficulties with the selection of clothes. In Leonardo da Vinci's diary there is a drawing of a naked man inscribed in a circle, in two superimposed positions. Based on the research of the Roman architect Vitruvius, Leonardo similarly tried to establish the proportions of the human body. Later, the French architect Le Corbusier, using Leonardo’s “Vitruvian Man,” created his own scale of “harmonic proportions,” which influenced the aesthetics of 20th-century architecture. Adolf Zeising, studying the proportionality of a person, did a colossal job. He measured about two thousand human bodies, as well as many ancient statues, and concluded that the golden ratio expresses the average statistical law. In a person, almost all parts of the body are subordinate to it, but the main indicator of the golden ratio is the division of the body by the navel point. As a result of measurements, the researcher found that the proportions of the male body 13:8 are closer to the golden ratio than the proportions of the female body - 8:5.

The art of spatial forms

The artist Vasily Surikov said “that in composition there is an immutable law, when in a picture you cannot remove or add anything, you cannot even add an extra point, this is real mathematics.” For a long time, artists have followed this law intuitively, but after Leonardo da Vinci, the process of creating a painting is no longer complete without solving geometric problems. For example, Albrecht Durer used the proportional compass he invented to determine the points of the golden section. Art critic F.V. Kovalev, having examined in detail Nikolai Ge’s painting “Alexander Sergeevich Pushkin in the village of Mikhailovskoye,” notes that every detail of the canvas, be it a fireplace, a bookcase, an armchair, or the poet himself, is strictly inscribed in golden proportions. Researchers of the golden ratio tirelessly study and measure architectural masterpieces, claiming that they became such because they were created according to the golden canons: their list includes the Great Pyramids of Giza, Notre Dame Cathedral, St. Basil's Cathedral, and the Parthenon. And today, in any art of spatial forms, they try to follow the proportions of the golden section, since, according to art critics, they facilitate the perception of the work and form an aesthetic feeling in the viewer.

Word, sound and film

The forms of temporary art in their own way demonstrate to us the principle of the golden division. Literary scholars, for example, have noticed that the most popular number of lines in the poems of the late period of Pushkin’s work corresponds to the Fibonacci series - 5, 8, 13, 21, 34. The rule of the golden ratio also applies in individual works of the Russian classic. Thus, the climax of “The Queen of Spades” is the dramatic scene of Herman and the Countess, ending with the death of the latter. The story has 853 lines, and the climax occurs on line 535 (853:535 = 1.6) - this is the point of the golden ratio. Soviet musicologist E.K. Rosenov notes the amazing accuracy of the ratios of the golden section in the strict and free forms of the works of Johann Sebastian Bach, which corresponds to the thoughtful, concentrated, technically verified style of the master. This is also true of the outstanding works of other composers, where the most striking or unexpected musical solution usually occurs at the golden ratio point. Film director Sergei Eisenstein deliberately coordinated the script of his film “Battleship Potemkin” with the rule of the golden ratio, dividing the film into five parts. In the first three sections the action takes place on the ship, and in the last two - in Odessa. The transition to scenes in the city is the golden middle of the film.

The proportionality of the earth is closely related to the proportionality of man.

Just as in nature there are five-petaled flowers, plants, the bodies of starfish, just as the human figure has a five-ray structure: a head, two arms, two legs, the human figure can be entered into PENTA WURF, with the parameters: the pose of a prone person with his arms spread 180 degrees and legs turned 90 degrees. And although the figures in pentagrams do not fit slightly into perfectly equilateral circles, the ratio is still present everywhere - 1.618 - i.e. "golden ratio"

Golden ratio and its secrets

(a+b)/b=b/a or x 2 -x-1=0;

What happens if you mirror it:

1+x+x2=x2-x-1;

1+0+0 2 =1;

1+1+1 2 =3

1+2+2 2 =7;

1+3+3 2 =12;

As you can see, with mirror reflection, magic numbers 1,3,7,12 are born, creating a number series of “lucky numbers”.

How not to admire the structure of the eyeball, where the distance between two points at the entrance and exit is projected according to the law of proportional dependence of refraction in the lens and turning up (real image) down (reflected image) onto the retina of the eye, where light-color perceptions of rods and cones encode spatial images of the external world and with the help of bioelectric impulses are transmitted to the cerebral cortex. So in reality, everything comes to our consciousness upside down and then turns upside down again subconsciously, creating an imaginary reality.

In the eye there is, as it were, a pyramidal crystal created by rays of light, joined by its vertices (a clock of time).

Proportionality, proportionality, analogy, commensurability.

It turns out that through visual perception the world around us is reflected in our consciousness and this connects the thinking of our “I” by analogy with the real world that surrounds us. That is, the harmony of nature creates the harmony of consciousness. Disharmony gives rise to anxiety, worry, nervous tension, and stress. This once again proves that man is part of nature. Many scientists and philosophers suggest awareness of the world as a consequence of the transition of the perception of images through abstraction and schematization, which leads to the logic of comparison, the development of cumulative memory and the emergence of the mind as it is with the ensuing consequences.

The formation of one person preserves the memory of the formation of all humanity. With countdown meditation, one can achieve recollection of the past, when information is absorbed from every cell of every atom in the same way that reflects the essence of existence. It was the brain-nature comparison that gave birth to the concept of microcosm and macrocosm. The simplest measurement of a person’s orientation in space is the vertical and horizontal, which ideally creates an omnipresent cross at the intersection. But any consciousness cannot think in infinite categories. Reality requires completeness. The most complete relationship between the vertical and horizontal is a certain inclined line joining two lines, this will be the third diagonal, which gives rise to the relationship:

a: b = c.

But why not a:a=c? Yes, because the eyeball itself precisely in the relation 3:4:5 gives birth to this relation. This ratio is ideal for the perception of the human eye in physiological terms.

The next step in reflecting similarity and commensurability is humanity’s awareness of dualism (the binary nature of similarity). Just as there are 2 eyes, 2 ears, 2 arms, 2 legs and so on, that is, the knowledge of symmetry is a mirror image of the axis. This is clearly reflected in these drawings:

As you can see, 2 interconnected squares with a circle inscribed inside give rise to the proportionality of the golden ratio.

And now you will learn a schematic understanding of the birth of a pyramidal crystal from 4 elements:

Adepts of antiquity considered this combination of a square, a circle, and a pyramidal crystal to be a general cosmic phenomenon of harmony, a symbol of the macroworld, and a person inscribed in these proportions was a symbol of the microworld.

Subsequently, this relationship was improved by initiations into secret knowledge by Agrippa Nepaceheimer in the “pentasymmetric law”, where there were 4 elements, 4 squares, combined with a star by 5 primary elements. To some extent, this is a unification of Western and Eastern philosophy, running along the Western and Eastern axes of the world.

Also, the search for a reflection of the microcosm was the laws derived by Vitruvius, Leonardo da Vinci, Dürer.

If you look closely, the starting points for the new circle and the square where the human figure is inscribed are taken from the original 4 squares, divided into 16 parts. This system of crushing into equal parts (doubling) corresponds to doubling on a fraction,

½, ¼, 1/8, 1/16, 1/32 (setata)

So the secret construction of the connection between the 4 elements and 5 primary elements eloquently confirms the direct relationship of the formula of the universe into one whole through a pyramidal crystal.

Example: Ancient adepts gave their names to the shape of rectangles built according to the golden ratio.

Conclusion: the harmony of man and nature was the main super task, the solution of which was the goal in itself of all civilizations. The tool for this was the fundamentals of global thinking through the relationship between the macrocosm and the microcosm through the construction of a pyramidal crystal based on the elements and primary elements.

The Great Pyramids are shaped like a semi-octahedron, where the lower semi-octahedron is implied. The shape of the upper semi-actahedron of the pyramid is not opposed to the surrounding space, but connects the zenith and the horizontal, unshakably and majestically rising above the earthly space, being an eternal symbol of harmony.

Secret knowledge that unites the macro and microcosm due to changing generations of formations and religions was gradually forgotten, separated and modified, which led to different interpretations of the same fundamentals. For example: the ancient Greeks, like the Egyptians, used a decimal (like modern society) number system (10, 100, 1000, and so on), which led to gradation.

Man - 1, God-man - 10. Accordingly, the construction of the temple suggested a tenfold increase in columns, cornices (Parthenon Temple). If you look closely, the proportionality of Greek buildings was a reflection of the harmony of the human body. In Rus', Byzantine masters who came with baptism also introduced ancient traditions and proportions, which was reflected in the architecture and interior.

The Middle Ages introduced a new understanding of the divine, where the root cause of everything (GOD) was presented as a disembodied spirit and invisibly present everywhere. Therefore, spiritual changes were made to the churches of the Byzantine school. Narrow windows, loopholes, where the rays of the sun fell, at a certain angle, and at a certain time.

The temple of antiquity filled with sculptures was replaced by an interior of paintings that expand the space, that is, creating the illusion of a supernatural space - part of the divine cosmos - the temple of some unearthly capsule of a spaceship descended into the world of everyday life.

After all, even during major wars, anyone who managed to get inside the church of the monastery was, as it were, guarded by God himself, and to punish those who hid in the church temple was considered an insult to GOD, sacrilege. And even in modern times, many, having committed many sins, try to hide in the church from punishment and confess their sins there.

The architecture of Christianity and Islam resembles the images of warrior warriors defending their faith, that is, the same associative images of the god-man, but on a different level than in ancient Greece or Rome. If in ancient Greece temples with a row of columns are a whole galaxy of gods, then Byzantine Christianity landed, grew into the ground, the temples became closed in on themselves, many loopholes-windows appeared, which speaks of civil strife and many years of wars between different faiths, and although the proportionality of the classical relations were preserved, but the wisdom of the past was dismembered and gradually became disunited, fading away in the contradictions of future generations.

The philosophy of the globality of the pyramidal crystal, left over from the supercivilization of the Atlanteans and at first supported by dedicated priests, was gradually forgotten due to the lack of education of ordinary people and the secrecy of the adherents. The barbarians did not understand the initiates, which led to natural destruction, the inability to understand the meaning of everything and everyone. Humanity is still gradually returning to the concepts of globality; scientific and technological progress modifies concepts, abstracts and accelerates the comprehensive understanding of the world to one generation of accumulated knowledge of the past. If earlier the movement went from the general to the particular by trial and error, now there is a process from the particular to the general, and the greater and deeper the knowledge about nature and man, the closer the approach to the formula of the universe, knowledge encoded in various forms handed down to us from the past.

The new millennium, where the 21st century is its beginning, and our generation is a monad - a unit (1), the beginning, represents a chance to determine a certain global plan - the basis of subsequent generations. After all, by and large, the process of global understanding of the understanding of the past by the present for the future has begun.

Even what is currently fantastic in practice is already in theory. As in ancient times, humanity realized, or rather rediscovered by trial and error, the concept of universal human values: ecological balance, sustainable development, dead-end and progressive methods of the state, methods of state development, the creation of a global information network was created, but most importantly, there was an awareness of recreating the global pyramidal philosophy, which appears and comes to the surface from the depths of non-existence, when civilization begins to mature and exert global changes, harm or benefit brought by economics, politics, sociology. Only by recognizing your mistakes can you become wiser and the 21st century is the era of sages, especially among the leaders of civilized countries, where a high standard of living contributes to careful management of the environment, conservation of natural resources, works of art, ancient monuments, development of savings systems, development of computer networks.

The modern world is not an endless space, but a closed organism, where a part can harm the interests of the whole. For example: 1 terrorist attack at a nuclear power plant can destroy hundreds of thousands of people and contaminate a number of states with radionuclides. It was the ancient adherents who supported the theory of globalization and were waiting in the wings.

Each of you can become initiated and enlightened. And what difference does it make which way you reach the top of the pyramid of true knowledge and skills. You are part of the whole, and you are responsible for it.

When a person is part of the whole, he is not afraid for his fate, because... fate leads it itself, the main thing is not to disturb the eco-balance everywhere.

The culture of the ancient world is a multi-level system created by the genius of man, who combined various sciences and arts, where the master was at the same time a thinker and nature was a subject for logical analysis of the environment, where the categories of space, philosophy of personality, form and content of matter, spiritual essences, which were based on combinations of musical sounds, mathematical numbers, picturesque colors, sculptural forms, architectural structures and all kinds of miracles created by the creative genius of the creative person.

Until recently, many attempts were made to comprehend the laws of nature differentiatedly, in parts, but the separate perception of natural phenomena by physicists, chemists, biologists, mathematicians led to the fact that the whole was divided into multiple ones, one-sided professionalism, due to unnecessaryness, destroyed the holistic perception of the world, and so that To introduce the general law of harmony, you need to find a certain discrete symbol that is the basis of everything. The particle from which everything else is made. The most suitable for this is mathematical modeling of any shape through geometric abstraction. Where there is a combination of systematic time and space. Forms and contents. Statics and dynamics. Visualization and schematization.

But nature itself tells us that the most ideal technique that gives life is dichotomy - a system of bifurcation of the whole into + and -, as well as the reverse phenomenon of merging + and - (male and female cells into one whole).

Examples:

Stage 1:

1. – maternal principle

Stage 2 +1/2 and -1/2 – division into 2 parts.

Stage 3: +1/2:2=1/4 and -1/2:2=-1/4. Dividing 12 into 2 parts again.

Stage 4: +1/2+1/4=3/4 A new quality is created that is not similar to stages 1, 2, or 3.

Conclusion: this example shows how from 1 method of dividing in half and then combining in different options gives rise to an infinite variety of combinations.

Let's introduce a mathematical concept: additivity - where in a number series each previous member of the series is equal to the sum of two consecutive

Drawing

2. Multiplicativity - where in a number series all members of the series are connected in a geometric progression.

Drawing

But in nature there is only one combination of additivity and multiplicativity of a global nature - this is the relation: a+b=c (additivity) and a/b=b/c (multiplicativity), in which the whole c is represented as consisting of two parts a+b.

Conclusion: But a sign of any self-organized system is:

1. Growth pattern.

2. Changing parameters.

That is, a single whole consists of two parts in a single organism, all parts grow according to the same law: the law of geometric progression. The idea of ​​similarity appears, which forms the basis for the development of living nature, on the basis of which the laws of genetics are based. Mathematically, this equation leads to the “golden ratio”, the golden numbers of a descending series. This is 1; 1.618; 2.618; and to the numbers of the ascending series: 1; 0.618, 0.382;

Indeed, taking the integer c as one c=1 from the equation a/b=b/c, we find that a=b 2 from the equation a+b=c

That b2+b-1=0

Drawing

But these relationships are static, and all life is dynamic. Dynamism can be reflected by vector equations, where a vector is the movement of a point in space and time.

In stage 3, diagonal dichotomy introduced linear incompatibility and angular inequality.

Drawing

Let’s create a “golden chain” and model the shape in multidimensional space – time.

When a right angle is introduced, the linear series of the golden section is transformed into a space of symmetry of similarities.

Proof:

Using the resulting drawings of an asymmetrical a-rhombus, an ascending branch of the golden ratio was obtained. The A-rhombus is a shape that evokes deep associations and relationships of any form of life, as it has aesthetic and mathematical properties.

After the previous constructions of vector geometry, when proto-eggs, proto-apples, and proto-shells appear from the drawing, I would like to consider the mystery of the birth of a living object from the primary element. Why does an apple tree grow from an apple seed, and a man from a human seed? Until then, it remains a mystery which bio-fields are embedded in the DNA gene spiral and form a given formula, because there is some kind of system, framework, axis that, as it develops over time, purposefully forms the necessary cells and tissues of living organisms. Since form is a category of space, areas of vector geometry can be applied to it; according to the principles of the pyramidal crystal of life, everything develops by analogy (what is above is also below).

Since man is inherently egocentric, two fundamental terms came to us from ancient times - macrocosm and microcosm (universe and man).

Modern cosmology assumes that by the time the universe was born, its mass, energy and pressure were already concentrated in the vacuum. Something similar exists in the human cell, where all the data of the human genome is concentrated. Now nanotechnologies are developing genetic engineering according to cosmological principles of “shocks” from “nothing”, when everything appeared everywhere and at the same time. Spectral analysis of stars confirms this. Nearby and billions of light-years distant galaxies are homogeneous in composition. According to vector geometry, where the mother’s cell is complemented by the father’s, a certain morphogenesis occurs inherent in the formation of these chromosomes, rigidly forming the framework of human-likeness.

Samir forms of living nature indicate 2 trends in shape formation in nature, which is confirmed by previous geometric constructions:

1. There is a pronounced direction of growth along the axis up and down - a biological vertical (stems of many plants, cereals, various phallic forms

2. There is an expression “the direction of growth towards spherical and rounded shapes” (human skull, apple, egg, orange).

3. There is an interpretation of flat shapes (sunflower disk, Pecten shell leaves, that is, the pyramidal crystal of life)

Introduction

“I like nothing but beauty

in beauty there is nothing but forms,

in forms - nothing but proportions,

in proportions there is nothing but number.”

Aurelius Augustine

For a long time, people have strived to surround themselves with beautiful things.

The household items of the ancient inhabitants already show man's desire for beauty. On

At a separate stage of his development, a person began to wonder: why this or that

an object is beautiful and what is the basis of beauty? Already in ancient Greece

The study of the essence of beauty, the beautiful, has formed into a separate science of aesthetics.

At the same time, the idea was born that the basis of beauty is harmony -

proportionality of parts and the whole, merging of various components of an object into one whole.

A person distinguishes objects around him by color, taste, smell, shape. Interest in the shape of an object may be caused by a vital necessity, or perhaps by the beauty of the form.

Beauty and harmony have always been the most important categories of knowledge, to a certain extent, even its goal, because ultimately the artist seeks truth in beauty, and the scientist seeks beauty in truth. The study of beauty has always been part of the study

the harmony of nature, the basic laws of its organization. Household items

Antiquity already shows man's desire for beauty. At a separate stage of his

development, people began to wonder: why this or that object is

beautiful and what is the basis of beauty? We also wanted to find the answer to this

We learned that the law of the golden ratio is widely used in fine arts, architecture, music, and even poetry. We were surprised that the perfectly proportioned human body is also entirely built on the principle of the golden division. Ancient sculptors were well aware of the use of the golden division to dismember the human body and knew how to use it; ancient statues are the best proof of this. You can check this peculiar law on any ancient statue. Modern researchers come to the conclusion that the Egyptians, back in the era of the ancient kingdom, developed a system of “harmonic proportioning” of the image, which is based on the principle of the golden division.

If the height of a well-built figure is divided into extreme and average ratios, then the dividing line will be exactly at the height of the waist, or, more precisely, the navel. If each of the resulting parts is in turn divided in extreme and average ratios, then the dividing line will again pass at very specific (anatomical) points: at the height of the so-called Adam's apple and the patella. But that's not all. Each individual part of the body - head, hand, etc. is also divided into natural parts according to the law of the golden division. In a word, the division of the external forms of a correctly folded human body is subject to the principle of the golden division down to the smallest parts.

We were also struck by the fact that the male figure satisfies this proportion especially well, and artists have long known that, contrary to general opinion, men are more beautifully built than women.

The last statement seemed more than controversial to us. We decided to study the structure of the modern human body.

Goal of the work: explore the principle of the “golden ratio” using the example of the human body.

Object of study: 8th grade students.

Tasks:

Get acquainted with the concept of the “golden ratio” and its use in life;

Consider the use of the “golden section” in human anatomy;

Find out from your classmates whether the concept of “beauty” corresponds to the rules of the golden ratio

Hypothesis: if a person’s body is built according to the “golden ratio” principle, then such a person can be considered beautiful.

Research methods: 1) analysis of information on this topic,

2) conducting a survey among classmates,

3) mathematical calculations of proportional relationships.

4) comparison of the obtained data.

Chapter 1. Theoretical foundations

History of the "golden ratio"

In the ancient literature that has come down to us, the first mention of the “golden ratio” is found in the works of Euclid “Principles” (about 300 BC). The “golden ratio” was known back in ancient Egypt and Babylon, in India and China. The great Pythagoras created a secret school where the mystical essence of the “golden ratio” was studied. Euclid applied it when creating his geometry.

The proportions of the Cheops pyramid, temples, bas-reliefs, household items and jewelry from the tomb of Tutankhamun indicate that Egyptian craftsmen used the “golden section” ratios when creating them.

What is the “golden ratio” or, in other words, the “golden ratio”? The golden ratio is such a proportional division of a segment into unequal parts, in which the entire segment is related to the larger part as the largest part is related to the smaller one, and this is approximately equal to 1.62, that is, c:d = d:c

Golden ratio in mathematics.

The division of a segment in the mean and extreme ratio is called golden ratio. Another name has become established in history - “ golden ratio."

Let, C AB, and produces, as they say, the “golden ratio” of the segment

AC: AB =CB: AC (1)

Golden ratio is called such a division of a segment in which the larger part is related to the whole as the smaller part is to the larger one.

If the length of segment AB is denoted by A, and the length of AC is through X, That (Oh)- the length of the segment CB, and proportion (1) will take the form:

(2)

In a proportion, as is known, the product of the extreme terms is equal to the product of the middle terms and we rewrite proportion (2) in the form:

x 2 = a (a – x).

We get a quadratic equation:

x 2 + ax – a 2 = 0

The length of the segment is expressed as a positive number, therefore, from two roots, you should choose the positive one

X=
or X =

Number
denoted by the letter in honor of the ancient Greek sculptor Phidias (born at the beginning of the 5th century BC), in whose works this number appears many times. Number
approximately equal to 0.61803398...

Thus, the parts of the “golden ratio” make up approximately 62% and 38% of the entire segment.

Golden figures.

Practical acquaintance with the golden ratio begins with dividing a straight line segment in the golden proportion using a compass and ruler.

Dividing a line segment using the golden ratio

From point B a perpendicular equal to half AB is restored. The resulting point C is connected by a line to point A. On the resulting line, a segment BC is laid, ending with point D. The segment AD is transferred to the straight line AB. The resulting point E divides the segment AB in the golden proportion.

Segments of the golden proportion are expressed by the infinite irrational fraction AE = 0.618..., if AB is taken as one, BE = 0.382... For practical purposes, approximate values ​​of 0.62 and 0.38 are often used. If segment AB is taken to be 100 parts, then the larger part of the segment is 62, and the smaller part is 38 parts.

Dividing a rectangle with the line of the second golden ratio

The figure shows the position of the line of the second golden ratio. It is located midway between the golden ratio line and the middle line of the rectangle.

Construction of a regular pentagon and pentagram

The pentagram served as a symbol of the Pythagorean Union. The Pythagoreans believed it was possible to achieve purification of the spirit with the help of mathematics. According to their theory, the world order is based on numbers. The world, they believed, consists of opposites, and harmony leads opposites to unity. Harmony lies in numerical relationships. The Pythagoreans attributed various properties to numbers. Thus, they called even numbers feminine, odd numbers (except 1) – masculine. The number 5 - as the sum of the first female number (2) and the first male number (3) - was considered a symbol of love. Hence such attention to the pentagram, which has 5 angles. The five-pointed star - the pentagram - is very beautiful, it’s not for nothing that many countries place it on their flags and coats of arms! Her beauty, it turns out, has a mathematical basis.

To build a pentagram, you need to build a regular pentagon. The method of its construction was developed by the German painter and graphic artist Albrecht Durer (1471...1528). Let O be the center of the circle, A a point on the circle, and E the midpoint of segment OA. The perpendicular to the radius OA, restored at point O, intersects the circle at point D. Using a compass, plot the segment CE = ED on the diameter. The side length of a regular pentagon inscribed in a circle is equal to DC. We plot the segments DC on the circle and get five points to draw a regular pentagon. We connect the corners of the pentagon through one another with diagonals and get a pentagram. All diagonals of the pentagon divide each other into segments connected by the golden ratio.

Each end of the pentagonal star represents a golden triangle. Its sides form an angle of 36° at the apex, and the base, laid on the side, divides it in the proportion of the golden ratio.

Construction of the golden triangle

We draw straight AB. From point A we lay down on it three times a segment O of an arbitrary size, through the resulting point P we draw a perpendicular to line AB, on the perpendicular to the right and left of point P we lay off segments O. We connect the resulting points d and d1 with straight lines to point A. We lay off the segment dd1 on line Ad1, obtaining point C. She divided line Ad1 in proportion to the golden ratio. Lines Ad1 and dd1 are used to construct a “golden” rectangle.

Fibonacci numbers

The series of Fibonacci numbers 1,1,2,3,5,8,13,21,34,55,89, etc. is closely related to the golden ratio. In this series, each subsequent number is the sum of the two previous numbers. Four centuries after Fibonacci's discovery of a series of numbers, I. Kepler established that the ratio of adjacent numbers in the limit tends to the golden proportion F. This property is inherent not only to Fibonacci numbers. Starting with any two numbers and constructing an additive series in which each term is equal to the sum of the previous two (for example, the series 7, 2, 9, 11, 20, ...), we discovered that the ratio of two consecutive terms of such a series also tends to the number  : the further we move from the beginning of the row, the better the approximation will be. If you take a calculator and divide each of them by the previous one, you get: 1:1=1; 2:1=2; 3:2=1.5; 5:3=1.666666; 8:5=1.6; 13:8=1.625; 21:13=1.615384;…

Golden ratio in art.

E Even during the Renaissance, artists discovered that any picture has certain points that involuntarily attract our attention, the so-called visual centers. In this case, it does not matter what format the picture has - horizontal or vertical. There are only four such points; they divide the image size horizontally and vertically in the golden ratio, i.e. they are located at a distance of approximately 3/8 and 5/8 from the corresponding edges of the plane.

This discovery was called the “golden ratio” of the painting by artists of that time. Therefore, in order to draw attention to the main element of the photograph, it is necessary to combine this element with one of the visual centers.

Moving on to examples of the “golden ratio” in painting, one cannot help but focus on the work of Leonardo da Vinci. His personality is one of the mysteries of history. Leonardo da Vinci himself said: “Let no one who is not a mathematician dare to read my works.”

He gained fame as an unsurpassed artist, a great scientist, a genius who anticipated many inventions that were not realized until the 20th century.

There is no doubt that Leonardo da Vinci was a great artist, this was already recognized by his contemporaries, but his personality and activities will remain shrouded in mystery, since he left to his descendants not a coherent presentation of his ideas, but only numerous handwritten sketches, notes that say “about everyone in the world."

He wrote from right to left in illegible handwriting and with his left hand. This is the most famous example of mirror writing in existence.

The portrait of Monna Lisa (La Gioconda) has attracted the attention of researchers for many years, who discovered that the composition of the picture is based on golden triangles, which are parts of a regular star-shaped pentagon. There are many versions about the history of this portrait. Here is one of them.

One day, Leonardo da Vinci received an order from the banker Francesco de le Giocondo to paint a portrait of a young woman, the banker's wife, Monna Lisa. The woman was not beautiful, but she was attracted by the simplicity and naturalness of her appearance. Leonardo agreed to paint the portrait. His model was sad and sad, but Leonardo told her a fairy tale, after hearing which she became lively and interesting.

Fairy tale

Once upon a time there lived one poor man, he had four sons: three were smart, and one of them was this and that. And then death came for the father. Before losing his life, he called his children to him and said: “My sons, I will soon die. As soon as you bury me, lock the hut and go to the ends of the world to find happiness for yourself. Let each of you learn something so that you can feed yourself.” The father died, and the sons dispersed around the world, agreeing to return to the clearing of their native grove three years later. The first brother came, who learned to carpenter, cut down a tree and hewed it, made a woman out of it, walked away a little and waited. The second brother returned, saw the wooden woman and, since he was a tailor, dressed her in one minute: like a skilled craftsman, he sewed beautiful silk clothes for her. The third son decorated the woman with gold and precious stones - after all, he was a jeweler. Finally, the fourth brother came. He did not know how to carpenter or sew, he only knew how to listen to what the earth, trees, grass, animals and birds were saying, he knew the movements of the celestial bodies and could also sing wonderful songs. He sang a song that made the brothers hiding behind the bushes cry. With this song he revived the woman, she smiled and sighed. The brothers rushed to her and each shouted the same thing: “You must be my wife.” But the woman replied: “You created me - be my father. You dressed me, and you decorated me - be my brothers.

And you, who breathed my soul into me and taught me to enjoy life, you are the only one I need for the rest of my life.”

Having finished the tale, Leonardo looked at Monna Lisa, her face lit up with light, her eyes shone. Then, as if awakening from a dream, she sighed, ran her hand over her face and without a word went to her place, folded her hands and assumed her usual pose. But the job was done - the artist awakened the indifferent statue; a smile of bliss, slowly disappearing from her face, remained in the corners of her mouth and trembled, giving her face an amazing, mysterious and slightly sly expression, like that of a person who has learned a secret and, carefully keeping it, cannot contain his triumph. Leonardo worked silently, afraid to miss this moment, this ray of sunshine that illuminated his boring model...

The portrait of Monna Lisa is attractive because the composition of the drawing is built on “golden triangles” (more precisely, on triangles that are pieces of a regular star-shaped pentagon).

The Golden Ratio and the Human Body

D Zealous sculptors knew and used the golden ratio as a criterion of harmony, a canon of beauty, the roots of which lie in the proportions of the human body. “The human body is the best beauty on earth,” stated N. Chernyshevsky. The great works of Greek sculptors: Phidias, Polykleitos, Myron, Praxiteles have long been rightfully considered the standards of beauty of the human body, examples of harmonious physique. In creating their creations, Greek masters used the principle of the golden proportion. The center of the golden proportion of the human body structure was located exactly at the navel. And it is no coincidence that the value of the golden proportion is usually denoted by the letter F; this was done in honor of Phidias, the creator of immortal sculptural works.

Albrecht Durer began developing the theory of proportions of the human body during the Renaissance. Dürer assigned an important place in his system of relationships to the golden section. A person’s height is divided in golden proportions by the line of the belt, as well as by a line drawn through the tips of the middle fingers of the lowered hands, the lower part of the face by the mouth, etc. Dürer's proportional compass is well known.

In subsequent centuries, the rule of the golden proportion turned into an academic canon, and when, over time, the struggle against academic routine began in art, in the heat of the struggle “they threw out the baby with the bathwater.” The golden ratio was “discovered” again in the middle of the 19th century. In 1855, the German researcher of the golden ratio, Professor Zeising, published his work “Aesthetic Studies”. He absolutized the proportion of the golden section, declaring it universal for all phenomena of nature and art.

Zeising did a tremendous job. He measured about two thousand human bodies and came to the conclusion that the golden ratio expresses the average statistical law. The division of the body by the navel point is the most important indicator of the golden ratio. The proportions of the male body fluctuate within the average ratio of 13: 8 = 1.625 and are somewhat closer to the golden ratio than the proportions of the female body, in relation to which the average value of the proportion is expressed in the ratio 8: 5 = 1.6. In a newborn the proportion is 1:1, by the age of 13 it is 1.6, and by the age of 21 it is equal to that of a man.

The proportions of the golden ratio also appear in relation to other parts of the body - the length of the shoulder, forearm and hand, hand and fingers, etc.

Zeising tested the validity of his theory on Greek statues. He developed the proportions of Apollo in most detail

Z The golden proportion was used by many ancient sculptors. The golden proportion of the statue of Apollo Belvedere is known: the height of the depicted person is divided by the umbilical line in the golden section.

But let's analyze other proportions of the famous statue. One of the highest achievements of classical Greek art can be the statue of “Doriphoros”, sculpted by Polycletus. The figure of the young man expresses the unity of beauty and valor, underlying the Greek principles of art. The broad shoulders are almost equal to the height of the body, the height of the head is eight times the height of the body, and the position of the navel on the athlete’s body corresponds to the golden proportion.

The distance from the sole of the spearman to his knee is j 3, neck height with head - j 4, length of neck to ear - j 5, and the distance from the ear to the top of the head is j 6. Thus, in this statue we see a geometric progression with the denominator j: 1, j, j 2 , j 3 , j 4 , j 5 , j 6 .

Chapter 2: Case Studies and Data Analysis

For the first time we encounter the concept of the “golden ratio” in a 6th grade mathematics course. We were interested in this concept and decided to study it. Before starting work on the topic “Golden Ratio,” we conducted a survey among students from grades 7 to 11 and teachers of our school. It was necessary to answer the question “Do you know what the “golden ratio” or “golden section” is? The survey results are shown in the diagram.

Most teachers know what the “Golden Ratio” and “Golden Ratio” are, and students from grades 7 to 11 have no idea about the “Golden Ratio” and “Golden Ratio”.

In order to check whether the golden ratio holds true in the proportions of the human body, we conducted research among 10th grade students. Each participant had two types of measurements taken: a measurement from the top of the head to the navel, and a measurement from the navel to the floor. Their ratio was compared with the ratio number of the golden ratio.

In order to select students for the study, we conducted a sociological survey “The Most Beautiful Classmate,” in which 56 people participated.

As a result of the survey, we identified 2 boys and 2 girls who, according to classmates, are the most beautiful.

We present the results.

Gryazeva A.

Borisova K.

Kuvinov V.

Semeletko R.

For the second study, we took measurements from the top of the forehead to the eyebrows and from the eyebrows to the bottom of the chin.

We compared the results with the numbers of the golden proportion.

Gryazeva A.

Borisova K.

Kuvinov V.

Semeletko R.

Based on the results of the study, we identified two students who best fit the golden ratio - Borisova K. and Semeletko R.

Conclusion: Our work proves that a person whose body obeys the rule of the “golden proportion” is considered truly beautiful.

Conclusion.

The importance of the golden ratio in modern science is very great. This proportion is used in almost all areas of knowledge. Many famous scientists and geniuses tried to study it: Aristotle, Herodotus, Leonardo da Vinci, but no one completely succeeded.

This paper discusses methods for finding the “Golden Section” and provides examples taken from art and anatomy.

In our work, we wanted to demonstrate the beauty and breadth of the Golden Ratio in real life.

At the beginning of our work, we were interested in the opinion of scientists that the male figure is built better than the female one. As a result of research, we found that in women the approach to the “golden proportion” is more pronounced than in men. Therefore, despite the assertion of ancient scientists, a woman is more beautiful than a man.

Research has proven that the human body obeys the golden ratio rule.

I would like to tell my contemporaries that the beauty of a girl, a woman, is not in the currently accepted volumetric indicators: 90 x 60 x 90, but in the proportionality of body parts proven by the ancients. I hope that my research work will help many to look at themselves differently. Obviously, the golden ratio has some special property; it contains a mystery of nature that has yet to be discovered. The golden ratio is a mathematical concept and its study is the task of science. But it is also a criterion of beauty and harmony, and these are already categories of art. Therefore, we will end our research work with poetry.

“Whatever life teaches us,

But the heart believes in miracles.

There is endless strength

There is also imperishable beauty"

From the history

"... If, from the point of view of the execution or function of an element, any form has proportionality and is pleasant, attractive to the eye, then in this case we can immediately look for in it any of the functions of the Golden Number... The Golden Number is not at all a mathematical invention. It is is in fact the product of a law of nature, based on the rules of proportionality."

A person distinguishes objects around him by their shape. Interest in the shape of an object can be dictated by vital necessity, or it can be caused by the beauty of the shape. The form, the construction of which is based on a combination of symmetry and the golden ratio, contributes to the best visual perception and the appearance of a feeling of beauty and harmony. The whole always consists of parts, parts of different sizes are in a certain relationship to each other and to the whole. The principle of the golden ratio is the highest manifestation of the structural and functional perfection of the whole and its parts in art, science, technology and nature.

Let's find out what the ancient Egyptian pyramids, Leonardo da Vinci's painting "Mona Lisa", a sunflower, a snail, a pine cone and human fingers have in common?

The answer to this question is hidden in the amazing numbers that were discovered by the Italian medieval mathematician Leonardo of Pisa, better known by the name Fibonacci (born about 1170 - died after 1228. After his discovery, these numbers began to be called after the famous mathematician. The amazing essence of the sequence Fibonacci numbers is that each number in this sequence is obtained from the sum of the two previous numbers.

The numbers that form the sequence 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, ... are called "Fibonacci numbers" , and the sequence itself is the Fibonacci sequence. This is in honor of the 13th century Italian mathematician Fibonacci.

There is one very interesting feature about Fibonacci numbers. When dividing any number from the sequence by the number in front of it in the series, the result will always be a value that fluctuates around the irrational value 1.61803398875... and sometimes exceeds it, sometimes does not reach it.
(Approx. irrational number, i.e. a number whose decimal representation is infinite and non-periodic)

Moreover, after the 13th number in the sequence, this division result becomes constant until the infinity of the series. It was this constant number of divisions that was called the Divine proportion in the Middle Ages, and is now called the golden section, the golden average, or the golden proportion.

It is no coincidence that the value of the golden ratio is usually denoted by the Greek letter F (phi) - this was done in honor of Phidias.

233 / 144 = 1,618
377 / 233 = 1,618
610 / 377 = 1,618
987 / 610 = 1,618
1597 / 987 = 1,618
2584 / 1597 = 1,618

CANON
The canon - a system of ideal proportions of the human body - was developed by the ancient Greek sculptor Polycletus in the 5th century BC. The sculptor set out to accurately determine the proportions of the human body, in accordance with his ideas about the ideal. Here are the results of his calculations: head - 1/7 of the total height, face and hand - 1/10, foot -1/6. However, to contemporaries the figures of Polykleitos seemed too massive and “square”. Nevertheless, the canons became the norm for antiquity and, with some changes, for artists of the Renaissance and classicism. Almost the canon of Polykleitos was embodied by him in the statue of Doryphoros (“Spear-bearer”). The statue of the youth is full of confidence; the balance of body parts represents the power of physical strength. The broad shoulders are almost equal to the height of the body, half the height of the body is at the pubic fusion, the height of the head is eight times the height of the body, and the center of the “golden proportion” is at the level of the navel.

For thousands of years, people have been trying to find mathematical patterns in the proportions of the human body. For a long time, individual parts of the human body served as the basis for all measurements and were natural units of length. Thus, the ancient Egyptians had three units of length: a cubit (466 mm), equal to seven palms (66.5 mm), a palm, in turn, equal to four fingers. The measure of length in Greece and Rome was the foot.
The main measures of length in Russia were the sazhen and the cubit. In addition, an inch was used - the length of the joint of the thumb, a span - the distance between the spread thumb and index fingers (their heads), a palm - the width of the hand.

The human body and the golden ratio

Artists, scientists, fashion designers, designers make their calculations, drawings or sketches based on the ratio of the golden ratio. They use measurements from the human body, which was also created according to the principle of the golden ratio. Before creating their masterpieces, Leonardo Da Vinci and Le Corbusier took the parameters of the human body, created according to the law of the Golden Proportion.

The most important book of all modern architects, E. Neufert's reference book "Building Design", contains basic calculations of the parameters of the human torso, which contain the golden proportion.

The proportions of the various parts of our body are a number very close to the golden ratio. If these proportions coincide with the golden ratio formula, then the person’s appearance or body is considered ideally proportioned. The principle of calculating the gold measure on the human body can be depicted in the form of a diagram.

The first example of the golden ratio in the structure of the human body:
If we take the navel point as the center of the human body, and the distance between a person’s foot and the navel point as a unit of measurement, then a person’s height is equivalent to the number 1.618.

In addition to this, there are several more basic golden proportions of our body:
the distance from fingertips to wrist and from wrist to elbow is 1:1.618
the distance from shoulder level to the top of the head and the size of the head is 1:1.618
the distance from the navel point to the crown of the head and from shoulder level to the crown of the head is 1:1.618
the distance of the navel point to the knees and from the knees to the feet is 1: 1.618
the distance from the tip of the chin to the tip of the upper lip and from the tip of the upper lip to the nostrils is 1:1.618
the distance from the tip of the chin to the top line of the eyebrows and from the top line of the eyebrows to the crown is 1:1.618

The golden ratio in human facial features as a criterion of perfect beauty.

In the structure of human facial features there are also many examples that are close in value to the golden ratio formula. However, do not immediately rush for a ruler to measure the faces of all people. Because exact correspondences to the golden ratio, according to scientists and artists, artists and sculptors, exist only in people with perfect beauty. Actually, the exact presence of the golden proportion in a person’s face is the ideal of beauty for the human gaze.

For example, if we sum up the width of the two front upper teeth and divide this sum by the height of the teeth, then, having obtained the golden ratio number, we can say that the structure of these teeth is ideal.

There are other embodiments of the golden ratio rule on the human face. Here are a few of these relationships:
Face height / face width,
The central point where the lips connect to the base of the nose/length of the nose.
Face height / distance from the tip of the chin to the center point of the lips
Mouth width/nose width,
Nose width / distance between nostrils,
Distance between pupils / distance between eyebrows.

Human hand

It is enough just to bring your palm closer to you and look carefully at your index finger, and you will immediately find the formula of the golden ratio in it. Each finger of our hand consists of three phalanges.

The sum of the first two phalanges of the finger in relation to the entire length of the finger gives the number of the golden ratio (with the exception of the thumb).

In addition, the ratio between the middle finger and little finger is also equal to the golden ratio.

A person has 2 hands, the fingers on each hand consist of 3 phalanges (except for the thumb).
