What does it mean to stand an egg in fortune telling?

The theory of vernal equinox holds that on the day of vernal equinox, the sun shines directly on the equator, and the gravity of the earth will change, and the gravity of the egg will change with the change of gravity, so the egg is easier to stand up.

Vernal equinox's position itself has its special significance in astronomy, but in fact, considering the gravity of the earth, vernal equinox itself has no special significance, except that the sun has turned to a certain position around the earth, which is related to the orbital plane of the earth's rotation and the orbital plane of the earth's revolution and the direction of these two orbits. Every day, its gravity will change slightly, and every day is different. To be precise, every day is different from time to time.

It turns out that the gravity of the earth does not change on the vernal equinox, but changes all the time. Therefore, eggs are not only attracted by gravity at every vernal equinox, but also at different times of the day. Therefore, there is no scientific basis for saying that it is easier to lay eggs at the vernal equinox. It seems that the reporter didn't lay an egg, which has little to do with the vernal equinox or not. It is very likely that he didn't master the correct method. So how do American men lay so many eggs? What are the secrets of successfully completing this game?

In order to understand the mystery of spawning, the reporter then consulted Mr. Liu Zhengyi, a physics expert. In order to clarify the reason why eggs can stand up, Mr. Liu made an analogy to reporters.

At the same time: my heart is on my only son, so now my center of gravity must pass through the supporting surfaces of my feet. So if I want to fall, the gravity line is always vertical, and I fall to a certain extent, as long as the gravity line does not pass through the supporting surface below, I will fall.

It turns out that this has nothing to do with whether the eggs are set up or not. It is purely a mechanical problem, and there are many tricks.

Choose an egg.

First, choose an egg with a big head and a small head. When laying eggs, the big head will face down, so the center of gravity will be lower, just like a tumbler, it is easy to keep balance.

Trick 2: Find support.

We did a small experiment, drawing inkpad on the desktop, and then standing the eggs on the inkpad-coated desktop. You can find that an egg that can stand will have a plane at the bottom that is difficult to see with the naked eye. Once the gravity line can pass through this plane, the egg can stand up.

The trick is to stay steady in three hands.

The position of yolk in raw eggs will also affect the position of eggs. Therefore, the hand that stands the egg should be kept as still as possible, so that the yolk can slowly settle to the lower part of the egg, so that the center of gravity can be low enough to keep the egg balanced.

Try these three unique skills of Teacher Liu. As long as you have enough patience, the egg will stand up obediently under your hands!
