Equinox and autumnal equinox are more suitable for vertical eggs.

It is reported that the most interesting custom on the vernal equinox is to lay eggs vertically. As early as 4,000 years ago, China had the tradition of dividing eggs in autumn to celebrate the arrival of autumn. So there is a saying that vernal equinox and autumnal equinox are more suitable for vertical eggs! The following is related content, welcome to read!

1 The most interesting custom of laying eggs on the vernal equinox is "laying eggs vertically": choose a smooth and symmetrical egg that has just been born for four or five days and gently stand it up on the table. When the vernal equinox arrives, the eggs will look good. On the occasion of the vernal equinox every year, many places in China hold "vertical egg" games or competitions.

Why should the vernal equinox erect eggs? According to historical records, the tradition of dividing eggs in spring originated in Great China 4000 years ago to celebrate the arrival of spring. In fact, standing an egg has nothing to do with the vernal equinox, just let the center of gravity of the egg be lower than the curve position of the maximum circumference in the middle of the egg. According to the ancient legend, the day of vernal equinox is the easiest day to lay eggs.

Vertical eggs actually have another meaning. Spring is coming, and everything is restless. Laying eggs is a good way to remind people to keep a good attitude and keep calm at any time.

Why did you choose to "lay eggs" at the vernal equinox? Can eggs stand up at ordinary times? What is the scientific truth of "laying eggs"?

Some people say that it is easy to stand an egg at the "vernal equinox" because the vernal equinox is a day as long as day and night in the northern and southern hemispheres, and the earth's axis tilted at 66.5 degrees is in relative balance with the earth's orbital plane around the sun, so it is easier to stand an egg successfully.

Others say that the "vernal equinox" coincides with the vernal equinox, the weather is lukewarm, the flowers are red and the grass is green, people are comfortable, their thinking is quick, their movements are neat, and it is also the easiest to concentrate and successfully stand the eggs.

The viewpoint in the book "Knowledge of Twenty-four Solar Terms" holds that vertical eggs have little to do with the vernal equinox. Because the egg surface is uneven, there are many protruding "hills". The height of "hills" is about 0.03 mm, and the distance between "peaks" is between 0.5 and 0.8 mm. According to the principle that three points determine a plane, just find three "hills" and the triangle they form, and then let the center of gravity of the egg pass through this triangle, the egg can stand upright.

Some experts believe that vertical eggs really have nothing to do with the vernal equinox and solar terms. Because the real factor that makes an egg stand up is gravity, an egg can stand up on any day of the year. The secret of vertical eggs is mainly "steady hands and patience, a pure heart."

The vernal equinox and vertical eggs contain scientific truth.

The vernal equinox is one of the 24 solar terms in China. Every spring equinox, tens of millions of people around the world are doing "vertical egg" experiments. I don't know why eggs stand up easily every spring equinox. How this toy, which is called "customized by China", became a "world game" is still difficult to verify.

The game of "vertical egg" is simple and interesting: choose a smooth and symmetrical fresh egg that has just been born for four or five days and gently stand on the table. Although there are many losers, there are also many winners. The vernal equinox has become the best time for vertical egg games, so there is a saying that when the vernal equinox arrives, the eggs will be beautiful. The eggs that stand up are very beautiful.

Why do eggs stand easily at the vernal equinox? Although there are many statements, the scientific truth is really not long. First of all, the vernal equinox is a day with the same length of day and night in the northern and southern hemispheres, and the inclination of the earth's axis of 66-50 degrees is in relative balance with the orbital plane of the earth around the sun, which is beneficial to vertical eggs.

Secondly, the vernal equinox is in the middle of spring, which is lukewarm, colorful, comfortable, quick-thinking, agile and easy to succeed in laying eggs.

More importantly, the surface of the egg is uneven and there are many protruding' hills'. The height of "mountain" is about 0.03 mm, and the distance between "peaks" is between 0.5 and 0.8 mm. According to the principle that three points form a triangle and determine a plane, as long as the triangle formed by three "hills" and these three "hills" is found and the center of gravity of the egg passes through this triangle, then the egg can stand up. In addition, it is best to choose eggs 4 15 days after birth, because the yolk of the egg is relaxed and the weight of the egg is reduced, which is beneficial to the erection of the egg.

The well-balanced and smooth curve of an egg is the reason why it is difficult to stand up, and it is also its charm. Leonardo da vinci, a famous European Renaissance painter, once forgot to eat or sleep for more than two years, and practiced drawing egg curves every day, which laid a solid foundation for his later success in shaping the mysterious smile of Mona Lisa.

In China, people call the face shape "face shape" and take the egg shape as the criterion for judging the beauty of the face shape, which fully shows the superb aesthetic level of China people and the aesthetic attributes of the egg shape.

However, for a long time, people have been unable to find the mathematical expression of the egg-shaped curve, and even mathematicians can only approximate the egg-shaped curve with rulers and compasses. No wonder the painters who drew thousands of "20,000 egg circles" also said that no two are exactly the same. It was not until modern times that mathematicians found the mathematical equation of egg curve and finally solved the problem of drawing egg curve for generations.

Today, egg-shaped cars, airships, bridges, tunnels, gymnasiums, concert halls and other buildings can be seen all over the world, which perfectly combine science and culture, science and art, science and aesthetics.

Perhaps, the popularity of these egg-shaped objects and buildings was inspired by the folk custom of "vertical eggs" during the ancient vernal equinox in China.

As early as 4,000 years ago, China had the tradition of dividing eggs in autumn to celebrate the arrival of autumn. In fact, the vertical egg has nothing to do with the autumnal equinox, but the center of gravity of the egg must be lower than the curve position of the maximum circumference in the middle of the egg.

In ancient legends, the day of the autumnal equinox is the easiest day to lay eggs. According to historical records, the tradition of dividing eggs in autumn originated in China 4000 years ago to celebrate the arrival of autumn. Oviposition reflects people's reverence and reverence for life and fertility.

According to astronomical experts, the autumnal equinox is the balance of time, the balance of day and night, and the stability of eggs standing is the best. There are also views that vertical eggs have nothing to do with the autumnal equinox, and they can be vertical on any day of the year. At the same time, China also has the folk custom of laying eggs on the autumnal equinox, and some places will hold interesting egg laying games or competitions on the autumnal equinox.

Why are eggs easy to stand on the autumnal equinox?

There is a saying circulating on the Internet: First, the autumnal equinox is the day when the northern and southern hemispheres are equally divided day and night, and the earth axis with an inclination of 66.5 degrees is in a relatively balanced state with the orbital plane of the earth, which is conducive to vertical eggs; Second, the autumnal equinox is in the middle of autumn. It's lukewarm, colorful and green. People are comfortable, quick-thinking and easy to succeed in laying eggs.

However, some experts believe that this is a purely technical issue and has nothing to do with the autumnal equinox. Eggs can be laid on any day of the year, and a stable egg can last for more than ten days without external interference. Some people think that the surface of eggshell is not smooth. As long as you find the right three surface particles, the whole egg can be held up like a chassis.

How to "lay eggs in the autumn equinox";

The surface of an egg is actually uneven, with many protruding "hills". The height of the "hills" is about 0.03 mm, and the distance between peaks is 0.5 mm to 0.8 mm. According to the principle of determining a plane by three points, as long as three suitable "hills" are found, the eggs can be erected. In addition, eggs born 4 ~ 5 days later are more conducive to the erection of eggs because of the relaxation of yolk, the sinking of yolk and the decline of center of gravity.

Other customs of the autumnal equinox: eat autumn vegetables and send autumn cows.

During the autumnal equinox, there are also interesting customs in China, such as eating autumn vegetables, sending autumn cattle and sticking birds' mouths.

Many places eat a kind of wild vegetable called "wild amaranth" in the autumn equinox, and some places also call it "autumn Artemisia". As soon as the autumnal equinox arrives, the whole family goes to pick autumn vegetables. Picked autumn vegetables are usually cooked with fish fillets, and the stewed soup is called autumn soup. There is a jingle that says "autumn soup is dirty, wash the liver and intestines." The whole family is safe and healthy. "

The autumnal equinox is coming, and in some places, people go door to door to send pictures of autumn cows. The picture is printed with red paper or yellow paper on the lunar solar terms all the year round, and also printed with farmers' ploughing patterns, which is called "Autumn Cattle Map". The pictures are all folk singers, who mainly say things like good luck in autumn ploughing that do not violate the farming season. Every time they go to a house, they say whatever they see until the owner is happy to give money. Although the words come out casually, every sentence is melodious, commonly known as "autumn", and autumn is called "Qiu Guan". This custom embodies people's good wishes for a bumper harvest.

On the autumnal equinox, there is a custom of cooking jiaozi in rural areas in many parts of our country. Besides eating by yourself, I have to cook twenty or thirty jiaozi without wrapping, and put thin bamboo sticks in the fields. This is "sticking the bird's mouth", which means that birds are not allowed to destroy crops.
