The golden section of the human body

The beauty of proportions in the human body is reflected in the golden section of the human body. German esthetician Cai Xin did a lot of calculations on the human body and found that there are four golden sections of the human body. That is the belly button, throat, knees and elbow joints. In terms of the human body structure as a whole, if the ratio of the two parts above the belly button and below the belly button is 0.618:1, it constitutes the golden section. As we all know, such proportions give people a sense of comfort and elegance. In addition, there are three golden sections on the human body. One is the part above the navel. Its golden section is at the throat. The ratio from the throat to the top of the head and the throat to the navel is 0.618:1. The other part is the part below the navel. Her golden section is at the knees. The ratio between navel to knees and knees to heels is 0.618:1. Another point is the upper limb. The golden section of the upper limb is at the elbow joint. The ratio from the shoulder joint to the elbow joint and from the elbow joint to the tip of the middle finger is 0.618:1. If the proportions of the four structures of the human body comply with the golden section, it will naturally look the best. For example, the Venus statue that people are familiar with is short, moderately beautiful, and is well-known by the world. The reason why she has such stunning beauty is inextricably linked to her perfect match of body shape and structure. Ancient Greek sculpture art "shows eternal charm", which reflects the outstanding achievements of people at that time in applying mathematical concepts and sculpture art. Here is the embodiment of the laws of proportion, balance, harmony, etc. in the beauty of form. These glorious arts serve as examples of the harmonious unity of principles of beauty and mathematical concepts.

It is said that the first person to discover this beautiful proportion was the Pythagoreans in ancient Greece. They took the trouble to divide the line segment into two different parts, repeatedly changing the proportions and comparing them, and finally found this "most elegant proportional rhythm". But the name "gold" for this ratio began with the famous Italian scientist and artist Leonardo da Vinci. From then on, 0.618 as the golden number, or golden ratio, dominated European architecture and art at that time, and affected many aspects of people's lives, and continues to this day.

The goddess statue in the center of the temple of Athena in Greece is carved from ivory and gold. The goddess's body is graceful and graceful, attractive. Expert research found that the ratio of the distance from the heel to the navel of her body to the entire height is exactly 0.618. Not only did the goddess Athena have such a beautiful figure, but so did the body proportions of many other Greek goddesses. In the famous book "Greek Myths and Legends" by the British painter Feilakman, he painted 96 pictures of beauties. The beauties in every painting are extremely charming and graceful. If you carefully measure their body proportions, they are similar to Athena.

Some people have also studied the bodies of ballet dancers and gymnasts. It was found that the ratio of the actress' waist length (that is, the distance from the heel to the navel) to the height is about 0.58, which is not as graceful as a goddess. Only when dancing gracefully, by lifting the heels and increasing the waist length by another 6-8 cm, can it be possible to approach the ratio of 0.618, thus making the dance more graceful. In other parts of the human body structure, 0.618 often appears, such as the ratio of hip width to torso length, the ratio of the length of upper limbs to lower limbs, the ratio of the distance from the chin to the eyes to the length of the entire head, the ratio of the distance from the top of the head to the tip of the nose and the ratio from the top of the head to the top of the nose. The ratio of chin length and so on is approximately equal to 0.618.

Not only the body structure, but also many conditions in the living environment are related to 0.618. For example, people feel most comfortable when the ambient temperature is 22-24 degrees Celsius. This is precisely because the product of a person's normal body temperature of 37 degrees Celsius and 0.618 is exactly 22.8 degrees Celsius. Around this temperature, the human body's metabolism and various physiological functions are in optimal condition. The pyramids of Egypt, the ancient civilization, are shaped like square pyramids and come in different sizes. But the ratio of the side length to the height of the base of these pyramids is close to 0.618. In many paintings and photographs, the central figure or scene is usually located at the golden section rather than in the center of the composition. Even the ratio of the width to length of ordinary leaves and the ratio of the length of a butterfly's body to the length of its wings when spread out are close to 0.618. The golden section, this wonderful ratio, is really breathtaking. No wonder the German astronomer Kepler declared that the golden section is the wonderful meaning given by the Creator to the natural world to continue the family lineage. From then on people called the golden section "the ratio given by God".

In addition, people also found that the position of the eyes is at the golden section of the face. So for these beauties from Berryz Studio, we will study the golden point of the figure based on the three conditions in blue font above. Segmentation:

1. The ratio of the height from the navel to the top of the head and the height of the human body.

2. The ratio of calf height to lower limb height.

3. The ratio of the height from the eyes to the hair and the height of the face.

Is it close to 0.618:1 (golden section)? The direct reflection in the figure is whether the gray line indicates whether the line is close to the change point (golden section point) of the blue-green scale. The green scale is 0.618 and the blue scale is 1. Because the photo is not taken at an angle completely parallel to the ground, it is difficult to have an accurate measurement. It is just a fun post-April Fools' Day joke.

The results yielded several surprising and reasonable findings:

1. Asians generally appear to have “short legs”, so the first data for each girl (upper limbs: lower limbs) All are on the large side.

2. The second data is completely the opposite. The ratio of the height from the sole of the foot to the lower edge of the knee and the height from the lower edge of the knee to the navel is 0.618:1, which is also due to the common body characteristics of Asians.

3. It may be due to the small head and short neck, which reduces the length of the upper limbs. MAIHA's body proportions are very close to the golden section, and it is almost the most perfect in the Berryz workshop.
