Two years later, after Li Jie got off duty, he made an appointment with Yang Tinghe and others to have a party together. When he walked to Zuixian Tower, he saw Yang Tinghe standing at the door waiting.
"Shenzhi, please let me wait. Doesn't this promotion make you more assertive?"
Li Jie smiled helplessly at Yang Tinghe's teasing. At first, he had some respect for this historical celebrity. The more he got in touch with him, the more he discovered that he was not forgiving and would tease Li Jie whenever he wanted.
"Both, each other, you didn't show off in front of me when you were promoted to Attendant."
Yang Tinghe curled his lips: "That's incomparable. Compared with you, my promotion speed is as slow as a turtle. You are soaring. You have been promoted twice in a row in two years. You are the envy of others!"
Li Jie was now serving as Zuo Chunfang Zuo Zhongyun of the sixth rank of the Imperial Academy. In the fourth year of Hongzhi, he completed the compilation of the actual records of the Emperor Xianzong. Due to his merit, he was promoted to editor of the Hanlin Academy (from the sixth rank), and Yang Tinghe was also promoted to the rank of imperial reader of the Hanlin Academy (the sixth rank of the full rank).
.
However, a few days ago, news came from Fujian that the method of drying salt was a great success. Fujian salt merchants no longer had to suffer from the hardship of holding on to their support. The emperor thought of his advice and had merit. In addition, Zhu Houzhao was about to turn 3 years old and passed the most dangerous period of premature death.
, Zhu Youtang had always intended to leave Li Jie to the prince, so he was promoted to Zuo Chunfang Zuo Zhongyun.
In the Ming Dynasty, there were four institutions to tutor the prince, namely James Mansion, Left and Right Chunfang, Economic Bureau, and Left and Right Chunfang. The official offices were located on the east and west sides of Wenhua Hall. Since the prince was too young and had not yet enlightened himself, Li Jie still had
As a lecturer at the Sutra Banquet, I have a lot of free time on weekdays except for lectures on duty.
"Jiefu, we will become a scene together when we stand down. It's better to go in quickly so that others won't wait too long."
Yang Tinghe looked around. The passers-by were not looking at them. He smiled awkwardly: "Let's go, let's go. By the way, Shenzhi, have you finished the "Preliminary Explanation of Arithmetic" written by you?"
Li Jie, who came from later generations, was well aware of the importance of mathematics. Mathematics is the cornerstone of all sciences. Since the Tang Dynasty, the Imperial Academy has established an arithmetic library and stipulated ten books on arithmetic as textbooks. However, because arithmetic was not taken seriously, many of them had been lost by the Ming Dynasty.
In view of this, Li Jie planned to write an introductory textbook on arithmetic. To this end, he went to the Siyi Museum to learn ancient Arabic. With the popularity of Zui Liuxia, Li Jie became richer and richer, and he also made a special trip to foreign businessmen in the capital.
The high-priced purchase of "Elements of Geometry" written by Euclid aroused a heated discussion among scholars.
Although his writing may not receive much attention now, as he gradually ascends to a higher position, all the books he writes will definitely be studied intensively by scholars all over the world. As long as some of the thousands of scholars can be interested in arithmetic, then
The effort he put in was worth it.
"It will take a while. Some time ago, Fan Shang delivered "Elements of Geometry" to me. I am currently translating this book."
Yang Tinghe paused: "Is it that strange book that offers a reward of a thousand gold? Is it worth it for a book written by Yi Di?"
Li Jie is well aware of the ancient people's thinking of the Celestial Empire, which believed that all people outside China are barbarians and Di. This kind of thinking is unacceptable. Since he has come, he must correct it in a timely manner.
"Jiefu, it is not that there are no civilizations outside of China. I heard Fan Shang say that thousands of miles away, there is an empire that has been passed down for thousands of years and has experienced nearly a hundred monarchs. It was established during the Southern and Northern Dynasties, and it is recorded in the books of the Later Han Dynasty.
, the name of the Great Qin State was Li Qian, because it was in Haixi, so it was also called the Haixi State, which was the Roman Empire mentioned by Fan Shang."
Yang Tinghe was shocked when he suddenly heard the news and staggered: "What? Such a thing actually happened? Shenzhi, are you kidding?"
Li Jie shook his head: "This is true. Unfortunately, thousands of miles away, a war decades ago destroyed this huge empire. The thousand-year-old city of Constantinople, known as the "Immortal City", has
After being captured, overseas is not all barren land, there are also civilizations that have been passed down for thousands of years, so overseas theory is not without merit."
Yang Tinghe was obviously shocked by what Li Jie said, so much so that he didn't say a word after arriving in the box. Qian Fu saw this and said, "Jie Fu, why didn't you say a word today? This is not like your character."
Qian Fu's words pulled Yang Tinghe out of his thoughts, and then he repeated to everyone what Li Jie had just said.
Everyone gasped after hearing this. This news overturned their previous understanding. If it were told by others, they would be ridiculed, but what Li Jie said was very credible.
Yes, everyone present knows that Li Jiecai has a comprehensive overview of the past and present, and there are no questions that he can't ask him on weekdays.
Yang Tinghe asked: "Shenzhi, why did you talk about this Haixi country for no reason today?"
Others also looked confused. In their eyes, Li Jie would not be aimless. After these years, everyone has become a small group with the same aspirations, and the leader is undoubtedly Li Jie.
When Li Jie saw this, he also said something from his heart: "In my eyes, arithmetic is very important. Calendar, water conservancy, construction, surveying, and taxation are all closely related to him. Even the military is not unrelated. The ordnance manufacturing of the Qin Dynasty
According to strict standards, the component errors are extremely small, and the parts can even be replaced with each other, which is something our country has not achieved."
Zhang Rui asked in confusion: "What does this have to do with the Haixi Kingdom you mentioned?"
"It has something to do with it. The capital of Haixi Kingdom was captured by firearms, and the development of firearms is inseparable from precision, and precision is naturally inseparable from arithmetic. Overseas, it is already the era of large ships and naval guns, and they attach great importance to the research and development of firearms. I have always thought about it.
How to make firearms more powerful, more accurate, and have a longer range, but what about us?"
After listening to this, everyone couldn't help but fell into deep thought. Under the influence of their ears and eyes, everyone was already accustomed to Li Jie's occasional novel words, because facts proved that what Li Jie said was often correct.
One time, Yang Shichang saw a rainbow after a rain. He was curious about where the rainbow came from, so he asked Li Jie. In the eyes of the ancients, rainbows were regarded as two-headed gods who could drink water. Li Jie simply made one in the sun.
Small waterfall, when the rainbow suddenly appeared, others were puzzled.
Li Jie told them about the refraction of light at that time, and everyone seemed to understand it. So what Li Jie said today did not seem so shocking to them.
Yang Tinghe was the first to speak: "Shenzhi, tell us what you think and we will listen to you."
"Yes, we listen to you."
"Listen to you."
…………
Li Jie saw the trust in everyone's eyes, and a warm current surged through his heart.
"I plan to finish "A Preliminary Explanation of Arithmetic" first. It is too small to immediately change people's ideas in the world by relying on our own strength. The road is still very long. We need to stand high enough and slowly improve our arithmetic.
Only the scholars in the world will study it carefully, and only after several generations of hard work can the results be seen."
Yang Shichang, as a die-hard loyalist, said without hesitation: "I support you. When I go home tonight, I will start training my son first. When the time comes, you can't refuse to become your teacher."
Others also echoed: "Yes, I am the beginning of my generation!"
