The Earth Circle Theory in Ancient Poetry
(Reading Zhang Hua's inspirational poems and Xin Qiji's magnolia is slow and poor today)
[Original]
Great instrument model luck, travel back to earth. Four gas scales, about cold and summer. Sparks are at dusk, and then it's autumn. The cool breeze vibrates and flows brightly.
-Excerpted from Zhang Hua's inspirational poems
Cherish this evening and the moon, where to go. There is another world. I'll meet you there, East of Light and Shadow. Heavenly sweating, Changfeng and Hao Hao send Mid-Autumn Festival. If the Tao is intact, the cloud will gradually become like a hook.
—— Excerpted from Xin Qiji's "Magnolia is slow, poor tonight."
[Mao Zedong's reading notes and conversations]
In a sentence written by Xin Qiji in the Song Dynasty, the moon came down from us and lit up other places. Zhang Hua of the Jin Dynasty wrote in one of his poems: "You can swim without looking back." .
-Excerpted from Every Prophet's Learned Revolutionary (see Reading Life in Mao Zedong, page 8, Sanlian Bookstore, 1986).
[analysis]
Zhang Hua (232-300) was born in poverty and became an official in the early years of the Western Jin Dynasty. His inspirational poem is a four-character ancient poem with 73 sentences. As the name implies, this is a self-encouraging work, showing good ambition and interest. The first few sentences of this poem are quoted in front, and it is intuitively felt that the changes of the four seasons are related to "running back and forth".
Mao Zedong read this poem from the source of ancient poetry. In this conversation in August 1964, he pointed out that this poem was included in the source of ancient poetry.
Xin Qiji's "Magnolia is slow, poor today's month" is prefaced by a small preface: "Drinking in the Mid-Autumn Festival must be Dan, and he also said that the former poem" Zeng Zeng Month "was used because of' Tian Wen'." This word is written to send the moon, and it is written in the form of Qu Yuan's Tian Wen, which is very novel. After careful observation and rich imagination, the author saw the moon rising in the east and setting in the west, and guessed that the earth was round and the moon revolved around it. This is a story in the history of astronomy. When Wang Guowei talked about this word in Ci on Earth, he said: "Poets can imagine and understand the reason why the moon revolves around the earth, and it is amazing to be in close contact with scientists."
Mao Zedong likes this word very much. In a book Jia and Short Sentences, he drew three big circles before the title of this word. Every sentence in the preface is circled; Draw a big question mark after each question in the word. 1964 Talking with Zhou Peiyuan and Yu Guangyuan about the earth circle thought contained in this poem. It can be seen that Mao Zedong's intentional painting of this poem not only appreciates the art, but also appreciates the profundity of the poet's argumentation thinking.

3. What are the ancient poems about the earth?
1, crossing the old friend Zhuang Haoran
This old friend prepared a delicious meal and invited me to his hospitable farm.
Green Woods surround the village and green hills are located outside the city.
Open the window facing the valley vegetable garden and pass the glass to talk about crops.
Please come here to see chrysanthemums when the ninth festival comes.
Vernacular translation:
My old friend prepared a sumptuous meal and invited me to his hospitable farmhouse.
Green Woods surround the village and green mountains span the city.

The Double Ninth Festival is here. Please come here to see chrysanthemums.
2. Liu Yuxi, one of the Tang Dynasties in Langtaosha
The Yellow River winds from a distant place, carrying thousands of miles of yellow sand.
Since you are from the sky, and now you seem to fly directly to the Milky Way, please take me to the sky, gather in the Milky Way, and go to the home of Cowherd and Weaver Girl together.
Vernacular translation:
The Yellow River in Wan Li twists and turns with sediment, and the waves are rolling, like a huge wind from the end of the world.
Today, we can go all the way along the Yellow River to the Milky Way, and we will visit the home of Cowherd and Weaver Girl together.
3. Liu Yuxi, the seventh Tang Dynasty of Langtaosha
In August, the waves roared, and the head was several feet high, touching the back of the mountain.
In a blink of an eye, I arrived at Haimen, and the rolled sand was like a snowdrift.
Vernacular translation:
In August, the sound of the waves is like Ma Benteng's roar. Several feet high waves rushed to the rocks on the shore and were beaten back.
In a blink of an eye, I retreated to the intersection of rivers and seas and returned to the sea. The sand it rolls up is like a pile of snow in the sun.
I am in the retreat of Zhongnanshan, Wang Wei.
After middle age, I have a strong kind heart, and I didn't settle down at the edge of Mount Zhongnan until my later years.
Interest concentration is often unique to play and have a happy thing to enjoy self-appreciation.
Sometimes go to the end of the water to seek the source, or sit and watch the ever-changing clouds rise.
Occasionally I met a village elder in the Woods, and I chatted with him until I often forgot to go home.
Vernacular translation:

When I am interested, I often go to play alone. When I am happy, I also have a good time and indulge myself.
Sometimes go to the end of the water to seek the source, or sit and watch the rising clouds change.
I happened to meet a village elder in the Woods. I talked and laughed with him and often forgot to go home.
5. Liu Tang Fang Ping in the moonlight.
The moonlight is deeper than half a house, and the big dipper is withered south.
Tonight, through the green screen window, I know that spring is warm and the sound of insects is fresh.
Vernacular translation:
The night is still deeper, and the moonlight only illuminates half of the family, and the other half is hidden in the darkness.
The Big Dipper is tilted, so is Nandou. I didn't know the arrival of spring until tonight. Outside the screen window reflected by leaves, the chirping insects came to the house for the first time.
4. Who said that the earth was round in ancient times?
Around 500 BC, the ancient Greek mathematician Pythagoras and his disciples first put forward great ideas.
The hypothesis that the earth is spherical. They advocate using mathematics to explain the universe, thinking that in all three-dimensional graphics, the sphere
Is the most beautiful. The shape of the universe should be spherical, and all celestial bodies in the universe, including the earth, should be
It should be spherical. It took Aristotle, a famous scientist and philosopher in ancient Greece 100 years to visit the earth for the first time.
Prove that the earth is spherical. He observed the celestial phenomena from the projection of the earth on the moon during the eclipse.
It is inferred that the shape of the earth is spherical. At that time, some people opposed it: if the earth is really
It is spherical. Why don't people who live on the other side of the earth fall into the air below? At that time,
Because people don't understand gravity, it is difficult to answer this question.
Zhang Heng, an astronomer in the Eastern Han Dynasty in China, once said that "the sky is like a chicken, and the ground is like a chicken yellow".
Compare the universe to an egg, and the earth is like the yolk in an egg. This theory is called Huntian theory, which is better than the previous theory of covering the sky.
Great progress has been made.
15 and 16 century's great geographical discoveries, especially1519-1521a ship led by Magellan.
The team successfully sailed around the earth, which provided strong evidence that the earth was spherical. In the late Ming Dynasty,
Western missionaries Matteo Ricci and Tang Ruowang came to China and introduced scientific knowledge such as astronomy, geography and mathematics.
Knowledge, the translated name of "Earth" appeared in China.
So, is the earth a round right sphere? /kloc-at the end of 0/7, British physicist Newton root
According to the theory of gravity he discovered, due to the inertial centrifugal force produced by rotation, the earth's
Matter moves in the equatorial direction, so he came to the conclusion that the earth should have an equatorial radius greater than the polar radius.
Flat sphere. However, according to their meridian survey, the faction headed by Cassini, director of the Paris Observatory,
According to inaccurate data, when the earth revolves around the sun, it should extend to the poles, and it is a long ball, not a flat ball.
Ball. This argument lasted for half a century. Voltaire, a French enlightenment thinker, argued about the shape of the earth.
Once said: "In London, it is considered an orange, but in Paris, it is imagined as a watermelon." Until 18.
In 1930s, the French Academy of Sciences sent two expeditions, one to Lapland near the Arctic Circle and the other to Lapland.
Peru, near the equator in South America, measured the meridian length between the two places, but found that Cassini's measurement results were as follows
Wrong, and Newton's inference is correct.
With the continuous progress of measurement technology, especially the use of artificial earth satellites, earth measurement is now
The equatorial radius is 6378 140m and the polar radius is 6356755m. The difference between them is 2 1385m, and its flatness is
1/298.2。 In this respect, the earth is much more round than oranges.
In addition, people also found from the measurement that the equator of the earth is not a perfect circle, but is similar to an ellipse, which is the largest.
The radius differs from the minimum radius by more than 200 meters. It is also found that the northern hemisphere of the earth is thinner than the southern hemisphere; Arctic region
The geoid (mean sea level) in this area is about 10 meter higher than that in the reference oblate sphere and Antarctic area.
It should be recessed about 30 meters. So some people compare the shape of the earth to a pear and describe the globe as a pear.
Body.
In fact, the earth is neither like an orange nor a pear, but a sphere with its own unique shape.
If this huge earth is shrunk into a globe with a diameter of 1 m, the equatorial radius is only polar.
The radius is greater than 1mm, which is a subtle difference that cannot be expressed on the globe, so we use it.
The globe is still round.
