Why did you choose the day of the spring equinox to set the egg?

? I would like to make this clear from three aspects, plus an extension -

First, what is called the spring equinox egg

Spring Equinox egg is also known as the spring equinox vertical egg, which refers to one of the 24 seasons of the spring equinox of this day every year, the popular folk "vertical egg games "The game is popular among the people on the day of spring equinox, which is one of the 24 solar terms every year. This vertical egg is not like Copernicus as the egg knocked up vertical, but must ensure that the egg is not knocked up under the premise of the egg, so that the egg vertical stand up.

Second, the origin of the spring equinox standing egg

? On the origin of the spring equinox egg, the historical record is relatively simple, just say: "Spring equinox egg" custom originated four thousand years ago, when the people to this activity to celebrate the arrival of spring. This record shows a few things: First, it shows that the origin of this time is very early, 4000 years ago in the Xia Dynasty. Secondly, it shows that the wisdom of our people was very developed 4000 years ago. You know, the Xia Dynasty is the first dynasty in China, then the "egg" time in the "spring equinox" this day, it is quite remarkable, why is it so? Please continue to see the following content.

? Third, the scientific basis of the spring equinox egg

? China's ancient times summarized the "Spring Equinox to, the egg is pretty " reasoning. The so-called "pretty", that is to say, in this day the egg is easy to be up, and other times will be more difficult. This contains a scientific reasoning.

? According to modern research, the vernal equinox is the northern and southern hemispheres, day and night are the same length of the day, 66.5 ° tilt of the Earth's axis and the Earth's orbit around the sun plane is in a state of relative balance of forces in favor of vertical eggs.

? What's more, the surface of the egg is uneven, with many protrusions like "hills". According to research, the "mountains" are about 0.03 millimeters high, and the distance between the peaks is between 0.5 and 0.8 millimeters. According to the principle that three points form a triangle and determine a plane, if you find three "hills" and the triangle formed by these three "hills", and make the line of the egg's center of gravity through this triangle, then the egg will stand up.

? In addition, it is best to choose eggs 4 to 5 days after birth, this is because at this time the yolk of the egg is flaccid, in the erection of the yolk can be made to sink, and the center of gravity of the egg falls, it will be conducive to the standing of the egg.

Fourth, the impact of the spring equinox standing eggs

? Originally a traditional game in China, or a spring equinox custom, nowadays it has become a world game. On the day of the spring equinox, so many people in the world are playing this game.

? In 1985, on the spring equinox, Gray, a professor of art at the University of Alaska, and his students, reportedly erected 24 eggs in a room.

? Please go and try to stand eggs on the day of the spring equinox! Let me tell you a secret, to make the eggs stand up, please pay attention to two points:One is to pay attention to the "mountain" when the eggs are standing up, and to be able to find the "triangle" formed by three "mountains"; the other is to be sure to find the "triangle" formed by three "mountains"; and the other is to be sure to find the "triangle" formed by three "mountains". One is to pay attention to the "mountains" when the egg is vertical, and to be able to find the "triangle" formed by the three "mountains"; the second is to be careful to let the yolk sink until the yolk moves exactly to the bottom shell!
