The golden ratio is an irrational number, defined as (√5- 1)/2. It is used in a wide range of fields, such as mathematics, physics, architecture, art and even music. The unique property of golden section is first applied to segment. What if the total length of a line segment is the golden ratio? The denominator plus the unit length of the numerator, if we divide it into two halves, the ratio of the long unit length of the denominator to the short unit length of the numerator, and the short line length to the long line length is the golden ratio.

golden section

The golden section is an ancient mathematical method. Its magical function and magic power are not clearly explained in mathematics, but in practice it is found that it can often play an unexpected role.

The golden section refers to dividing a line segment into two parts so that the ratio of one part to the total length is equal to the ratio of the other part to this part. Its ratio is an irrational number, expressed as a fraction (√5- 1)/2, and the approximation of the first three digits is 0.6 18. Because the shape designed according to this ratio is very beautiful, it is called golden section, also called Chinese-foreign ratio.

Aesthetic value of golden section;

Because it has aesthetic value in plastic arts, it can arouse people's aesthetic feeling in the design of length and width of arts and crafts and daily necessities, and it is also widely used in real life. The proportion of some line segments in the building adopts the golden section scientifically. The announcer on the stage is not standing in the center of the stage, but standing on the side of the stage. The golden section stands in the most beautiful position on the stage length and has the best sound transmission.
