Looking at the things placed on the table, Zhao Bing was a little funny. In fact, this was a globe. Of course, it was not a "precious" collection in the magical express that followed him here, but was imitated based on it. Of course, the text on it has been replaced with the current traditional Chinese characters, and the place names on various continents are more blank. Because the great geographical discovery has not yet begun, people's perception is limited to Asia, Europe and Africa, and it will take two hundred years before the discovery of the Americas, and Oceania will be delayed a little.

But now this is a shoddy globe that every modern primary school student has, and maybe it is not as detailed and accurate as theirs. But at this moment it is an unprecedented new thing, scaring all three people. I can't understand what magical thing this is, and I can't understand how his Majesty brought out a strange thing.

"Do you know what this is?" Zhao Bing asked a few people with his fingers.

"I don't know!" The three of them shook their heads and said depressedly.

"This is actually where we live!" Zhao Bing said.

"How is it possible for us to live on the ball?" Chen Dun's head was almost shaken to the back of his head, and he firmly denied it.

"Your Majesty is joking. Why don't you slide down when standing on it?" Jiang Chaozong was half confused and half unbelievable.

"Your Majesty said yes, that's it!" Seeing both of you looking at him, Ni Liang said without changing his expression.

Zhao Bing watched the performance of the three people without comment. Until they talked about everything they should say and shouldn't say. Finally, when he realized that His Majesty had not spoken, he quickly shut up, "How did Your Majesty get this?" Jiang Chaozong said embarrassedly.

"I calculated it!" Zhao Bing said coldly.

"Is it calculated?" Jiang Chaozong said in surprise.

"Yes!" Zhao Bing nodded and pondered for a moment, "I have already discovered the problem you mentioned, but I have never solved it. Until this Northern Expedition, we seized many maps of the Mongolian Yuan, and combined with the sea charts I have collected in recent years and maps of various countries, we tried to splice them into a general map, but found that it was difficult to compatible with the maps of our dynasty, and barely splicing them together was seriously distorted."

"His Majesty found the reason?" Jiang Chaozong asked anxiously. He knew that the young emperor liked to collect maps and nautical charts since he was a child. In addition to the contributions of book collectors, there were also those who bought, robbed, and seized from the hands of the Mongol Yuan and Semu people. It is said that thousands of copies have been collected.

"I found that the methods of surveying and mapping maps of the barbarians are very different from ours, and they are more accurate than ours. So I tried to learn from their methods and modify them. After calculation, I embedded them into our existing maps. This is the result!" Zhao Bing patted the globe.

Although he was an excuse, he was not entirely nonsense. The ancient Romans made far less contribution to cartography theory than the Greeks, but they were the makers of practical maps and made many travel guides. The tradition of practical road maps did not disappear. At the same time, due to the need for navigation, a brand new type of map was evolved - pilot maps - pilot maps. Some maps and travelers entered China with Mongolia's western expedition and commercial exchanges.

However, the "Mercator projection method" used in drawing large world maps did not appear after more than 200 years. It is an important projection method invented by him in drawing. The meridians in the figure are parallel straight lines, intersecting at right angles with the latitude line drawn as straight lines. This is a similar cylinder projection (in this projection, the interval between latitude lines becomes larger as it is farther away from the equatorial line, so as to keep the intersection angle of longitude and latitude lines unchanged. These parallel lines are therefore called "gradual latitude lines", reflecting the curvature of the earth.

It is also not forgotten that the work of filling China into the world map was also completed by Europeans, although this sounds exciting. In the late Ming Dynasty, Matteo Ricci's world map was regarded as a clever thing by officials and scholars, but no one focused on the technical connotation of this map.

During the Qing Dynasty, Emperor Kangxi hired Europeans to draw maps of China with the latest surveying and mapping technology out of intellectual curiosity and the intention of understanding his ruling territory for more powerful control, but he had no intention of promoting modern mapping technology. Instead, he locked the "Imperial Yu Quanlan Map" into the deep palace and was not allowed to be viewed casually.

During the Qianlong period, Jesuits Fu Zuolin and Gao Shensi were invited to survey and map the Junggar, Xinjiang and Erut Mongolian areas that had just been pacified. The Jesuits Jiang Youren was written and added to the "Imperial Yuquan Painting" for the "Unified Yuquan Map", but after completion, it was also locked in the shelf.

Later, Tang Weile's China map result "Huangyu Quanlan Map") was based on the measurement results of the Kangxi Dynasty. The freshness and accuracy of its data are self-evident. This map is a topographic map that highlights the mountain water system. The outline is close to the part of the map of today's China, and embedded it in the world map, becoming the most accurate full map at that time.

What Zhao Bing did was actually much simpler. With chickens, there would naturally be eggs. He just needed to make up a lie and then use the backward push method to get the role. But all of this was done with caution. He did not dare to use it for others. He used the personnel in the imperial office to complete it. However, those people only knew why, and did not know the specific application. The final work was also done by him. But as soon as it was released today, a few people still shocked.

"Is this the result of Your Majesty's calculation?" Looking at the two flat sketches that Your Majesty took out, the appearance of a flat pumpkin was indeed not in a square shape, but in a flat pumpkin. After being put together, it was almost a hemispherical. After being assembled, it turned out to be a ball. After Jiang Chaozong was a professional, he calmed down from the shock and entered the state.

"Yes, this result is indeed unexpected, but the calculation result is like this, but many problems can be explained clearly." Zhao Bing nodded and said.

"How do you say this?" Jiang Chaozong asked anxiously.

"You think that when we were in Qiongzhou, it was like summer. Although there were four seasons in Jiangnan, it was not as clear as those in Jiangbei. Why is this?" Zhao Bing fiddled with the globe and asked and answered, "I think it was Qiongzhou close to the north and south center line, which was closest to the sun, and gradually moved away from south to north, so there was a distinction between four seasons."

"Your Majesty, it seems to be wrong!" Jiang Chaozong nodded, shook his head and said, "If it is as Your Majesty said, from far to near, there shouldn't be four seasons changing, but the hot and cold are constant."

"Well, you're asking!" Zhao Bing nodded, picked up a cup to gesture as the sun, "So I think it's very likely that the ball we live in is inclined and revolving around the sun. Of course, this is just my assumption, and further verification is needed."

Of course, Zhao Bing knew that in this era, the geocentric theory still ruled the world, and that China was the center of the world, and that his statement was really arbitrary. He also understood that maps not only have political and military functions, emphasizing its function in shaping territory consciousness. Under the world pattern of nation-states, the close relationship between the use of maps and the display format, concepts, consciousness, and power.

Which map is used, what is emphasized on the map, what is downplayed, what is circled on the map and what is out, draw a map with where is the visual center, and draw more and less in the boundary area, it is actually driven by specific concepts. In its development process, it not only reflects the progress of human geographical knowledge and surveying and mapping technology, but also shows the evolution of various "subjective" views such as human worldview, group view, regional view, and cultural view.

The most popular example is that Matteo Ricci showed Ming officials a traditional European world map with land arranged on the Atlantic as the center, which immediately made Ming officials unhappy. So he changed the map to land arranged on the Pacific Ocean as the center, and Ming officials thought that China's central position in the world was clear. In fact, Matteo Ricci did not make obvious distortions of the map itself, but just changed the visual center, so the concepts expressed changed - the concepts that Ming officials hoped to achieve were presented.

Of course, it is said that Matteo Ricci, a European, is smart enough to capture and achieve the conceptual demands of Ming Dynasty officials. The Ming Dynasty officials are real conceptual manipulators here. They believe that the world map must express the traditional worldview of the Chinese, and no matter what the world is actually like. The essential reason for this manipulation is that when facing Matteo Ricci, a lonely foreigner, the Ming Dynasty officials were in power.

Although Zhao Bing is now in power, he is alone in this issue. If others dare to say this, he may not be killed on the spot and be half-dead by spitting stars and locked up as a mental illness. Therefore, he still has to be careful in challenging China's traditional doctrines for thousands of years, otherwise he will be ousted by everyone in unison and let his son, who is under one year old, succeed to the throne.

"Your Majesty, this is too shocking!" Chen Dun, the 'stupid bold', felt that His Majesty's thoughts were too transcendent. If it was spread, I'm afraid that all the gods and ghosts would rebel. They said that they were in charge of the world. We changed our masters in the blink of an eye!

"Your Majesty, I think it's better not to spread this matter for the time being, so as not to cause shock to the government and the people!" Jiang Chaozong was also a little cowardly. He didn't expect that he just asked a small question, but eventually he caused a shocking secret. This was equivalent to challenging the saints of the three schools of Buddhism, Taoism and Confucianism, and his little shoulders could not help it.

"Your Majesty said this, it must make sense. Don't be so careful!" Ni Liang was still full of confidence in the little emperor and did not question what he said.

"Brother Ni, this matter is very important, so you need to be careful in your words and must not be spread outside!" Chen Dun and Jiang Chaozong looked at each other, their eyes full of contempt for being uneducated, but he knew that he should still comfort him, otherwise it would be troublesome to leak a word.
