Jang Young-sil, father of Joseon science

The title of the drama is 'Plop Plop Love.' Yoon Doo-joon plays King Sejong and Kim Seul-gi plays Jang Young-sil. In the drama, Jang Young-sil is a current high school senior and time-slimbs her past to spread various scientific technologies and return to the present. Almost all adults in Korea know this name, but it is unknown when and how it was born and how it disappeared. I'm more mysterious because of that fact. The drama was very popular because the writer's imagination melted well. Jang Yeong-sil, who is not well known for her fame. Who is he? Is he really from the future like the imagination of the drama?

Genius scientist appearing like the wind

There are two main stories about Jang Yeong-sil's birth.
The first argument is from the Yuan Dynasty.

According to the Annals of King Sejong, Jang Yeong-sil's father Jang Seong-hui was from Sohangju (now Soju and Hangzhou) in the Yuan Dynasty, and his mother was a government official of Dongnae Prefecture in Joseon. The basis of this story is in the records of the Annals of King Sejong, but it is fully understandable if you understand the social atmosphere of the late Goryeo Dynasty.

If we big number 2 in the case to foreign domination the 20th century Japanese occupation of Goryeo Dynasty, Yuan is the interference. The 35 years of Japanese rule were literally when the Yuan Dynasty was "intervention" in the Goryeo Dynasty if it was forcibly occupied. In other words, it was called the "interference period" because it was literally a time when our country, institutions, and customs were politically dominated to the extent that they could be maintained. Of course, at that time, the king of Goryeo had to marry a princess of the Yuan Dynasty and become a son-in-law, and he had to pay various tributes, including a princess. However, in the process of becoming the emperor's son-in-law and featuring figures such as Empress Ki, a unique phenomenon occurs. There was cultural exchange between people. The Goryeo Dynasty was the Goryeo Dynasty when Goryeo culture such as dumplings, clothes, shoes, and hats were handed over to the Yuan Dynasty, while the Goryeo culture was established in Goryeo, which was also called Mongo-pung. The typical Mongo-pung are the "jokduri" of the bride, the "Yeonji" of the ball, the suffix of "chi," which means a person like a merchant or a government employee, the king's table, and the court lady's "Mu-suri.

If you look at these phenomena, it's been 70 years, but it's more like an exchange than a clash of cultures. In fact, King Sejo of the Yuan Dynasty praised the Goryeo people for being "better in terms of technology than Koreans who only collect taxes and recite poems," and established the "Korea Confucian Academy" to specialize in studying abroad. In addition, King Chungseon had academic exchanges with a school called 'Manggundang' in the capital of the Yuan Dynasty, and there were also exchanges of baduk with doctors. In other words, it is common for people of the Yuan Dynasty to go to Goryeo and settle down in the Yuan Dynasty. In particular, many technicians who grow horses in Jeju Island and handle what they call "mokho" come to Jeju Island from the Yuan Dynasty. Depending on the situation, Goryeo deliberately brought people with special skills from the Yuan Dynasty to Goryeo. It's sort of a scout. They also arrange marriages to settle down the engineers who brought them to Korea. At that time, there were many gisaengs among those who married the people of Yuan Dynasty.

In this context, it is persuasive that an engineer from the Sohangju area of the Yuan Dynasty married a gisaeng belonging to the Goryeo government.

The second claim was made by Chang Yeong-sil, who was naturalized during the mid-Goryeo period in North Song.

Dongguk Yeoji Seungram has a record of Jang Yeong-sil as the 'master of Asan'. According to the Asan Jang Clan's Association, Jang Seong-hui, the father of Jang Yeong-sil, was a third-class government official at the end of the Goryeo Dynasty, and his wife and son Jang Yeong-sil were reduced to Joseon's conduit during the period of turmoil from Goryeo to Joseon. However, if you are from a noble family that has fallen, you will not be able to know the family of Jang Yeong-sil, who was already appointed during the reign of King Taejong.

Anyway, I think it is more important that Jang Yeong-sil was recognized as an inventor in Dongnae-hyeon, the present Busan area, than the authenticity of her birth, and that she was selected by King Taejong to enter Hanyang.

In the old days, the meaning of astronomy is very special. The king regarded him as a special being from heaven, not just like ordinary people. The stories of Hwanung and Ungny of Gojoseon, and the stories of Goguryeo and Gaya all emphasize their connection with heaven. The king is the son of heaven and it is the king's unique authority and duty to know the reason of heaven. That's why it's a special area where no one can or shouldn't study. In 1395, four years after the Joseon Dynasty's founding, the creation of the astronomical observation map, "Cheonsang Train Map," also symbolically expressed the opening of a new sky.

From a scientific point of view, astronomy also has a special meaning. In agricultural countries, the change of seasons and weather is more important than anything else. The reason why the king was sacrificed when a bad harvest occurred in Buyeo in ancient times is not simply because the royal authority was weak, but because the king is the closest to heaven to release the anger of heaven. By recording the changes of the day and the changes of the seasons, the calendar, which is now called the calendar, has also developed. The solar calendar centered on the movement of the sun and the lunar calendar centered on the movement of the moon, and the 24 solar terms. In the West, the criteria for reverse law are changed to those of Julian and Gregorian forces, and Northeast Asia follows the Chinese calendar for quite a long time. Korea followed the Chinese calendar until the Joseon Dynasty according to the principle of power.

A phenomenon such as the solar eclipse phenomenon is a big spectacle now, but in the old days, it is a big change in the sky. It's time to believe that if you don't have proper manners in the sky, you can be angry. In other words, when an eclipse occurs, the king's courtesy toward the sky becomes a very important event that raises the king's authority.

But here's the problem. The world now uses the standard time zone based on the Greenwich Observatory in England, which is 0 degrees longitude. Our country uses the same time zone as Japan and China uses Beijing time zone. There is still an hour difference between Korea and China. Of course there was a time difference like this in the old days. Therefore, the time calculated from China's perspective and the time calculated on our Korean Peninsula will inevitably differ as we have followed the Chinese calendar. If a king has to remain absent-minded for a long time at a very important event that raises the authority of the king, it becomes a serious problem in itself. There are quite a few records of officials being punished for miscalculating the actual solar eclipse time. Sejong feels that there is a fundamental problem, not a mistake made by bureaucrats, and feels the need to study Joseon's own unique astronomy. Sejong also plans and implements two strategies to invent Joseon's own dynamics.

One was to send Jang Yeong-sil to China in 1421 (the 4th year of King Sejong's reign) along with Yun Sa-ung and Choe Cheon-gu to learn the shape of astronomical instruments. 먹튀 없는 토토사이트 소개

Of course, in China, the celestial gate is a state secret, so the imperial observatory, "Hueumgam," is an important institution that no one can enter without the emperor's order. There was nothing much to learn from a flawed official because security was so strictly enforced that it prevented him from contacting and discussing with other officials. Jang Young-sil does not give up and starts searching the bookstore in Beijing. Since there were many exchanges with the West, there were many books not only from China but also from Arabia and the West, and Jang Yeong-sil studied on her own using books from bookstores. So I studied for about a year and came back to Joseon to start research and production. Sejong elevates his status to support Jang Young-sil's Appoint a member of the Chamber of Commerce, a government office that manages and supplies king's clothing or royal wealth, to a separate seat corresponding to five bells (or five articles). From now on, it became a formal official rather than a slave, and in 1432 (the 14th year of King Sejong's reign), in 1438 (the 20th year of King Sejong's reign), it was built in a humble state, and a spirit tablet was installed.

Another is to give Yi Sun-ji a special mission to study industry-academia (now mathematics). The visual acuity of the Yuan Dynasty is already excellent, with 365.2425 days of solar power, almost the same as it is now. The Julian calendar, which was used for a long time in medieval Europe, had an error of about 12 days a year and then changed to the Gregorian calendar in 1582, but the development of astronomy and industry in China was excellent. The problem is that there was no one in Joseon to understand the mathematical methodology used in early vision. It was useless because there was no one to understand the principles of early vision from the Yuan Dynasty and the newly changed great power from the Ming Dynasty. So Sejong wanted to train math experts because he wanted to change the basics, and that's Lee Soon-ji. In 1427 (the 9th year of King Sejong's reign), Yi Sun-ji was first assigned to Seungmunwon, which deals with diplomatic documents, but from the 15th year of King Sejong's reign, he began to specialize in industrial and industrial studies. And 20 years later, the result is Chiljeongsan Mountain. Chiljeongsan Mountain is a method of calculating the operation of seven celestial bodies, including the Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn. It is largely divided into the inner and outer parts, and the inner parts were newly compiled based on the early vision, which was the most accurate method of Chinese calendar, and the outer parts were compiled by Yi Sun-ji and Kim Dam directly based on the Korean translation of the Islamic calendar.
