Who is right about the two children s debate, and the two children are right?

The sun is the same distance from the earth in the morning and at noon. Why does the sun look bigger in the morning than at noon? It's a visual error, an illusion.

The same object, placed in a group of objects larger than it, appears small, while placed in a group of objects smaller than it appears large. In the same way, the morning sun rises from the horizon against the backdrop of trees, houses, distant mountains and a small corner of the sky, and in this comparison, the sun appears larger. At noon, when the sun rises high and the vast sky is the backdrop, the sun appears smaller.

Secondly, the white part of the same object appears larger than the black one, and this physical phenomenon is called "photoosmosis". When the sun is rising, the background is a dark and dreary sky, and the sun is exceptionally bright; At noon, the background is a blue sky, and the sun does not contrast much with its brightness, so it appears smaller.

The temperature is higher at noon than in the morning, is the sun closer to us at this time than in the morning? Neither is it. The main reason is that the sun hits the earth obliquely in the morning and the sun shines directly on the earth at noon.

At the same time and in the same area, direct radiation is higher than oblique heat. At the same time, at night, the heat of the sun shining on the ground dissipates, so it feels cool in the morning; At noon, the heat of the sun hits the ground, so it feels hot. The temperature is hot or cold, and it does not indicate how far or near the sun is from the ground.

It is said that the beginning of the day is cool.

No one is right. The two children talked about the distance of the sun from the earth, and each came to opposite conclusions based on unilateral phenomena. Confucius was ridiculed by them for failing to answer this question due to the limitations of his scientific level at the time.

This story tells us that if we look at the problem one-sidedly, we will not be able to draw correct conclusions.

In our northern hemisphere, in summer, the distance between the sun and the earth is hundreds of millions of kilometers; In winter, the distance between the Sun and Earth is slightly shorter, about 100 million kilometers. But this is the change in the distance between the sun and the earth in half a year. And during the day, from morning to noon, the position of the Earth in its orbit changes very little.

Therefore, the distance between the sun and the earth in the morning is equal to the distance between the sun and the earth at noon.

Extended information: "Two Children's Debate Day" is an essay written by Liezi, a thinker during the Warring States period.

Two Children's Debate Day".

Confucius traveled eastward, saw two children arguing, and asked why. A son said: "I go near at the beginning of the sunrise, and I am far away in the middle of the day."

A child is far away at the beginning of the day, and the middle of the day is near. A son said: "The beginning of the day is as big as a car cover, and the middle of the day is like a plate, this is not for the far small and the near is big?"

A son said: "The beginning of the day is cool, and the middle of the day is like a soup, this is not hot for the near and cold for the far?" "Confucius can't decide.

The two children smiled and said, "Who knows more about you?" ”

This is also a very educational fable. It tells the story of Confucius's encounter with two children arguing about the distance of the sun, and Confucius was unable to make a decision. At the same time, it also praised Confucius's spirit of seeking truth from facts and daring to admit that his knowledge is insufficient, and the spirit of the ancient people who dared to explore objective truth, and could think independently and boldly question.

The whole text expresses the characters and the storyline through dialogue description, the character language is very personalized, and the characters are clearly visible and lifelike.

Two children debated the Japanese "Ancient Texts".

Confucius traveled eastward, saw two children arguing, and asked why.

A son said, I go to people at the beginning of the day, and the middle of the day is far away. A child is far away at the beginning of the day, and the middle of the day is near.

One said: "The beginning of the day is as big as the cover of a car, and in the middle of the day it is like a plate." Isn't this small for the far and big for the near? ”

Yi'er said: "The beginning of the day is cool and cool, and the middle of the day is like a soup." Isn't this hot for the near and cold for the far? ”

Confucius is not able to decide. The two children smiled and said, "Who knows more about you?" ”

Sentence meaning: Confucius went on a study tour in the East, and when he saw two children arguing, he stepped forward to ask why.

One child said, "I think the sun is close when it first rises and far away at noon." Another child thinks that the sun is far away in the morning and close at noon.

One child said, "The sun is as big as a car canopy in the morning, and as small as a pan at noon." Isn't it that the trembling code collapse is big when it is close to us, and small when it is far away?

Another child said, "The sun is very cool in the morning, and at noon it feels as hot as reaching into the boiling hot water.

Confucius could not judge. The two children smiled and asked, "Who said you are wise and knowledgeable?"
