Why do we stand eggs upright during the Spring Equinox?As early as 4,000 years ago, China had the tradition of standing eggs on the Spring Equinox to celebrate the arrival of spring. In fact, standing an egg upright has nothing to do with the Spring Equinox.According to ancient legend, it is easiest to stand an egg upright on the Spring Equinox. Astronomers said that according to historical records, the tradition of standing eggs on the Spring Equinox originated in China 4,000 years ago to celebrate the arrival of spring. It is said that this is the day when it is easiest to stand an egg upright, and there is some scientific reason for this. According to experts, the vernal equinox is the day when the day and night are equal in the northern and southern hemispheres. The Earth's axis, which is tilted at 66.5 degrees, and the orbital plane of the Earth's revolution around the sun are in a state of relative balance of forces, which is very conducive to standing an egg upright. Secondly, the vernal equinox is in the middle of spring, which is neither too cold nor too hot, with red flowers and green grass. People feel relaxed, their minds are quick, their movements are agile, and it is easy to successfully stand an egg upright. What are the techniques for standing eggs upright?Key point 1: When choosing eggs, you should first choose eggs with one end larger than the other. When standing the egg, place the large end facing downwards so that the center of gravity will be lower, like a tumbler, making it easier to maintain balance.Point 2: Find a supporting surface . To find a suitable supporting surface, we did a small experiment. We applied ink on the table and then stood an egg on the table with ink. You can find that the egg that can stand up has a plane at the bottom that is difficult to see with the naked eye. Once the line of action of gravity can pass through this plane, the egg can stand up. Key point three: Keep your hands steady. Since the position of the yolk in a raw egg will also affect the egg's standing condition, the hand holding the egg should be kept as still as possible to allow the yolk to slowly settle to the bottom of the egg. This way, the center of gravity will be low enough to keep the egg balanced. Summary: The above is [How many days until the 2018 Spring Equinox? Why do we stand eggs upright during the Spring Equinox? 】, I hope the entire content can be helpful to everyone! |
