The theory of the earth's sphere originated from China.
China has a civilization of 5,000 years. Apart from the war on the table, science has been developing. Where is the sky round? Is China's earliest knowledge of the universe. At first, this special theory was regarded as the cycle of human energy. Huangdi Neijing put forward five movements and six qi and the changes of four seasons, which were repeated one year later.
In innate gossip, the sky is dominant, the earth is secondary, the sky is yang and the earth is yin. They interact with each other, resulting in the creation of all things in heaven and earth, among which man is the essence of heaven and earth, so he is regarded as the spirit of all things in heaven and earth, who can understand all things and is the most spiritual.
With the development of Taoist astronomy theory, Tian Wenpian was born in the Spring and Autumn Period and the Warring States Period. Among them, there is the idea that the earth is round. In the Western Han Dynasty, Luoxiahong was an astronomer in China. First person? He created other calendars in taichu calendar and taichu calendar, and now the twenty-four solar terms we often say also come from this book.
In addition, he also put forward the theory of "Huntian", that is, the earliest theory of "Earth Circle". Many people think that the armillary sphere was invented by Zhang Heng in the Eastern Han Dynasty. In fact, Zhang Heng improved Xia Hong's armillary sphere, but the seismograph is his masterpiece.
Why was the seismograph deleted?
During the Eastern Han Dynasty, earthquakes were relatively frequent. During the thirty years from the 4th year of Yonghe (AD 92) to the 4th year of Andi Yan Guang (AD 125), 26 major earthquakes occurred. In order to prevent earthquakes, after decades of research, Zhang Heng finally invented the waiting wind seismograph in the first year of Yangjia (AD 132).
However, due to more than 2000 years of war, there are not many historical records about Hou Feng Seismograph, only the Book of the Later Han Dynasty. Zhang Hengchuan only recorded the word 196, and later generations also added some historical records according to this word 196, such as Taiping Yulan in the Northern Song Dynasty. The "technical department" is used: the earth shakes, the dragon spits pills, and the toad opens its mouth to collect pills, and the sound is exciting.
According to these historical records, modern experts repaired the seismograph. At present, a man named Wang Zhenduo, who is on display in the China History Museum, designed and restored it, and the beads in Longkou will not fall off. Due to the lack of historical documents, seismographs have always been controversial. In order not to mislead students, the seismograph was cancelled in the history textbook.
Why is the armillary sphere printed on Korean banknotes?
The won was officially issued on August 4th, 1975. When the Korean won is issued, the currency value is based on the Japanese yen, ranging from 1 yuan to 1 ten thousand yuan. Generally speaking, the larger the amount, the more difficult it is to exchange, and Japan has cancelled some large denominations. However, the economic development of Korea in the past 60 years has not caused.
In 2007, the new version of the Korean won issued 6,543,800 yuan banknotes, with the head of King Sejong on the front. King Sejong is the fourth king of the Li Dynasty. During his reign, he founded the Korean script, and in 1446, he promulgated "Cultivating the People's Correct Voice". His achievements are so great that he is called by later generations. King sejong? .
The background on the back is the song of the five peaks of the sun, the moon and the dragonfly, but the pattern on the back is an armillary sphere, which is the general name of armillary sphere and elephant. The armillary sphere is an instrument for measuring the celestial sphere, like an instrument used to demonstrate celestial phenomena in ancient times.
Printing the armillary sphere on King Sejong's back has raised questions not only from China netizens, but also from South Korea. Has Korea completed its application for World Heritage? Dragon Boat Festival? After that, are you going to apply for the armillary sphere?
Wen Chongliang, a history professor at Seoul National University, expressed dissatisfaction with printing. He admitted that the armillary sphere was made in China, and China's armillary sphere should not appear on North Korean currency. Korean netizens have also fry. They all agree that South Korea has its own? Huntianbiao? Why use Huntian?
Regarding the use of the armillary sphere, the Bank of Korea also responded that the box-shaped design of the armillary sphere is not compatible with the Korean currency pattern, so the armillary sphere was chosen as the pattern, but what about this? The armillary sphere? It is not China's armillary sphere, but a part of the armillary sphere watch. Koreans are dissatisfied with this far-fetched explanation.
But the issuance of money is a very cautious thing. What about this time? The neglected nuthatch is a disrespect for the history of China and South Korea, but the currency issued does not mean that it can be cancelled, not to mention 6,543,800 yuan and Sejong King's Korean currency.
abstract
On the other hand, China's 5,000-year-old civilization has a great influence on neighboring small countries. Just one Chinese character has been passed down for thousands of years. Although Korea has been applying for the World Heritage, nothing can change it. Korea was once a part of China. When Zhou was conquered, his uncle moved to South Korea. Ji Zi Hou Guo? .
