The great kingdom of mathematics consists of 0-9, points, lines and surfaces. Don't underestimate these members, they make our life wonderful. For example, this humble point makes our life more beautiful and faster. This credit must belong to the golden section.
Divide a line segment into two parts, in which the ratio of one segment to the line segment is equal to the ratio of the other segment to the first segment, and the ratio is about 0.6 18, which is the golden section point.
Since ancient Greece, people have thought that applying the golden section to plastic arts can give people the most beautiful feeling. Therefore, the golden section is widely used in life.
First, the application of drawing.
1, drawing rectangles is the most common and familiar thing for our primary school students. Do you know how to make a rectangle more beautiful and give people a more comfortable feeling unconditionally? That is, the ratio of the width to the length of the rectangle is close to 0.6 18, which makes the drawing more beautiful.
2. Anyone who has studied drawing may know that if you are given a piece of paper and fill it up, it may not look good, but if you just draw a little, it will not look good if you leave a lot of blanks. But some paintings make people feel beautiful and refreshing. That's because it uses the golden section, which is pleasing to the eye.
Second, the application of the human body.
1, in the structure of the human body, the golden section is widely used, give a familiar example. People often say that handsome men and beautiful women are the most beautiful figures, that is, their face width and face length ratio, and their leg length and body length ratio are all around 0.6 18.
The navel is the golden point of human body, and the knee is the golden point of human leg.
Third, the application of architecture.
At all times, many architects prefer 0.6 18, and their outstanding figures are admired by the world. Such as the pyramids in ancient Egypt, Notre Dame de Paris and the Eiffel Tower in France.
Fourth, the application in life.
1, you may notice that the electrician always chooses the golden section of the wire for inspection when checking the non-conductive wire, because it can find the damage most quickly.
2. The aspect ratio of most doors and windows in our house is also 0.6 18. The golden section is applied to boxes and books to make these items look more comfortable.
The world is beautiful, and the golden section is everywhere. Let's create more beauty with knowledge and wisdom!
Introduction to mathematics:
Mathematics [English: Mathematics, derived from the ancient Greek μ θ η μ α (má th ē ma); Often abbreviated as math or maths], it is a discipline that studies concepts such as quantity, structure, change, space and information. Mathematics is a universal means for human beings to strictly describe the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence.
In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics. Mathematics plays an irreplaceable role in the development of human history and social life, and it is also an indispensable basic tool for studying and studying modern science and technology.
