Why did ancient humans stand up pole to measure images?

We can easily grasp the time now, we have understood the laws of the revolution and rotation of the earth and the sun, and it is relatively easy for us to grasp the time and the change of the seasons. We can buy a lot of clocks, we can control the time in many countries and different regions, these are all based on modern science and technology. However, in ancient times, they did not have the corresponding scientific cognition, and they only relied on some laws of life to judge the change of time and seasons.

1. In order to grasp the changes of time, the ancients were the first human beings, who all worked at sunrise and rested at sunset, and their lives were often determined by the rise and fall of the sun. In primitive agrarian societies, this method was very practical and practical, and the day's work was prescribed. But with the development of society, we have more and more other needs, not only to sleep and plow, those ancients have to find a way to divide time reasonably, so that they can do what at what time.

I began to invent and observe, so that I could better grasp the time. <>

2. The observation time of the pole is very convenient, because in ancient times, some of their things were not developed, such as the sun ghost, these things were also things that they only realized later, and at the beginning, they only observed the length of the shadow of the thing to judge the time to which step. At noon, the shadow is the shortest, and the ancient people of our country also discovered this truth, so they chose to measure it with a pole. The pole is easy to find, he does not have to be limited to such high requirements, and they judge the time only to play a preliminary role in making judgments, not very accurate, the pole is very convenient, and the requirements for materials and sites are not high.

Ancient human beings also had a mutation of consciousness, they not only stayed at the extremes of two aspects of their lives, they also needed other more accurate measurements, and the better and better the days, the higher and higher the requirements for their lives. They continue to develop and create, but also to meet their various needs, to make their lives more convenient, ancient humans are also wise people. The benefits they bring to their own lives are also the basis for the development of science later.

It has laid the foundation for a series of innovative ideas.

This is because in ancient times, people did not have clocks, so they did not know the specific time, so they used the method of pole imaging to record the time for people to identify.

This is a manifestation of the wisdom of the ancients. The ancients could use shadows to record the specific angle of the sun's movement, so as to calculate the time of the day.

The purpose of pole measurement is to know the time, and the ancients also had a strong concept of time.
