Prince of Chaos

Chapter 193 The arrogance of Xu Guangqi

Zhong Huamin was flustered in the wind.

His Royal Highness the crown prince who is full of careerism is also thinking about women.

However, the sensible Zhong Huamin didn't say anything.

Zhong Huamin stood aside in embarrassment and said, "You can just ask the painter in the palace to study this painting of Eunuch Sun. It's not difficult."

Sun Xian asked in disbelief, "Really?"

Zhong Huamin said: "Yes, Eunuch Sun. This kind of painting is simple and plain, focusing on the outline of the characters and the realism between light and shadow. The painters should understand after careful study a few times."

When Sun Xian heard Zhong Huamin's answer, he finally felt relieved, and then Sun Xian said carefully to Zhu Changluo: "Master, you give the painting to the servant, and the servant asks the painter to study it carefully. Try to let them give all the paintings to Zhu Changluo as soon as possible." You draw it."

Zhu Changluo said: "Okay, then I will reward you. Anyway, this painting is also painted by you, and there is no place to frame it if you stay here in this palace. You can take it back to Dongchang and enjoy it for yourself."

Sun Xian was overjoyed. He really liked this portrait. He bowed to Zhu Changluo, "Thank you, master."

After thanking Zhu Changluo, Sun Xian looked at Zhong Huamin again, and said, "Master Zhong, is it convenient for you to leave some money?"

When Zhong Huamin heard Sun Xian's question, he was stunned.

"This"

Zhu Changluo looked at the thick-skinned Sun Xian, and at the hesitant Zhong Huamin. He understood what Zhong Huamin meant. How could a civil servant give a portrait of an eunuch?If this gets out, this official will never want to do it again.

Zhu Changluo said directly to Sun Xian: "Okay, don't be a good boy if you get a bargain. Go back and get down to business."

After Sun Xian heard Zhu Changluo's impatient voice, he didn't dare to beg anymore, he quickly put away the portrait and knelt down.

After Zhong Huamin waited for Sun Xian to leave, he saluted Zhu Changluo, "Thank you for your consideration, Your Highness."

Zhu Changluo said: "It's nothing. I asked you to paint the painting. If you don't tell me, I won't tell you, and Sun Xian doesn't dare to say it. But your painting skills are quite good. You have also learned it. sketch?"

Zhu Changluo asked this question casually.

After Zhong Huamin heard the word "sketch", a portrait he had seen at Xu Guangqi's house flashed across his mind, and he finally remembered where he had seen this kind of painting.

Zhong Huamin said: "I haven't learned it before, but I know where I have seen this kind of painting drawn by Your Highness."

After Zhu Changluo heard Zhong Huamin's words, he looked at Zhong Huamin in surprise. He couldn't believe that Zhong Huamin said that he had seen sketches.

Zhu Changluo asked, "Where did you meet?"

Zhong Huamin said: "I saw it in the home of a young man."

Zhu Changluo asked, "What's the name of this young man?"

Zhong Huamin said: "Xu Guangqi."

After hearing the name of Xu Guangqi, Zhu Changluo couldn't help saying "I know this person well" in his heart! Although I haven't read "The Elements of Geometry", I was once abused by Geometry.

Zhu Changluo couldn't help asking again with surprise: "Which yamen does he work in now?"

Zhong Huamin said: "Xu Guangqi has not been an official yet, he is just a scholar now."

Zhu Changluo is messed up, Xu Guangqi?Scholar?how is this possible?Isn't he a very big official?If Zhu Changluo remembers correctly, Xu Guangqi was still in the second assistant high position in the end, how could he be a scholar?

In fact, Xu Guangqi at this time is really a scholar. He was selected in the 25th year of Wanli, which is next year, and he is really a scholar now.

Zhu Changluo asked again: "Where is this Xu Guangqi?"

Zhong Huamin said: "Return to Your Highness, he has returned to his hometown in Shanghai County."

Zhu Changluo was disappointed and said: "I'm back to Shanghai, it's a pity that I didn't have the chance to meet again."

Zhong Huamin didn't understand why Zhu Changluo suddenly asked about Xu Guangqi, but he also saw Zhu Changluo call it a pity when he heard Xu Guangqi returned to his hometown, which made Zhong Huamin a little puzzled.

Zhong Huamin said: "Has Your Highness heard of Xu Guangqi's name?"

When Zhu Changluo heard Zhong Huamin ask him this way, he knew that his expression was overly nervous.

Finally, Zhu Changluo replied ambiguously: "I seem to have heard someone mention it."

After Zhong Huamin heard Zhu Changluo's answer, he couldn't ask any more questions. Finally, Zhong Huamin bowed to Zhu Changluo, and then left Ciqing Palace.

After Zhong Huamin left, Zhu Changluo thought quietly about Xu Guangqi alone for a while.

Xu Guangqi was also a milestone figure that cannot be ignored in the late Ming Dynasty.There are many achievements in his life.

Among them, the most talked about is "The Elements of Geometry" that he translated together with Matteo Ricci. For those who have studied the history of junior high school, Xu Guangqi is a character that cannot be avoided when studying the history of the Ming Dynasty.Although he didn't ride the wind and waves like Zheng He, he also learned how big the world is from Matteo Ricci.

But these can't summarize his life, because his achievements are more than just meeting a foreigner and translating a great work of mathematics.

He also has high attainments in agronomy. He is proficient in agronomy and has written many books, such as "Nongzheng Quanshu", "Sweet Potato Shu", "Nongyi Miscellaneous Shu", "Nongshu Draft", "Taixi Water Law" and so on. is one of his achievements.

In addition to these, Xu Guangqi is also proficient in astronomy. The compilation of the "Chongzhen Almanac" almanac is a proof. The concept of a round Earth is introduced, and the concepts of longitude and latitude are introduced.

He also provided the first all-day star map based on the Tycho star catalog and the traditional Chinese star catalog, which became the basis of the later Qing dynasty star catalog.In terms of calculation methods, Xu Guangqi also introduced the accurate formulas of spherical and plane trigonometry, and first made corrections for parallax, air difference and time difference.

Moreover, in addition to the editor-in-chief of the "Chongzhen Almanac", Xu Guangqi also participated in the specific compilation of books such as "Testing the Sky", "The Great Test", "Ridan Calendar Finger", "Measuring the Complete Meaning" and "Daily Watch" .

The completion of these achievements will enable Xu Guangqi to leave his name in the history of Chinese astronomy and illuminate the past and present.

Of course, Xu Guangqi's achievements are far more than that.

As for his achievements in mathematics, Xu Guangqi is not far behind.

Xu Guangqi's greatest contribution in mathematics was the joint translation of "Elements of Geometry" (the first 6 volumes) with Matteo Ricci!

Xu Guangqi put forward the practical idea of ​​"the study of degrees", and also wrote two books, "Pythagorean Justice" and "Measuring Similarities and Differences".Xu Guangqi first used the term "geometry" as a professional term for mathematics.

The translation of "Elements of Geometry" has greatly influenced the original habits of Chinese mathematics learning and research, and changed the direction of Chinese mathematics development. It is a major event in the history of Chinese mathematics.

However, it was not until the end of the Qing Dynasty that the imperial court abolished the imperial examinations and promoted schools, and elementary geometry with "Elements of Geometry" as the main content became a compulsory subject in secondary schools.

Moreover, in Xu Guangqi's revision of the calendar, he also discussed in detail the role of mathematics in astronomy and calendar, water conservancy engineering, rhythm, weaponry and military engineering, accounting and financial management, various construction projects, machinery manufacturing, geodetic surveying, medicine, and clock making. There are ten applications of the leak timer.Sub-disciplinary studies in these areas are also recommended.

If the emperor at that time had approved Xu Guangqi's request, perhaps a comprehensive research university could have appeared in this ancient land of the East 300 years in advance.

Of course, in addition to this, Xu Guangqi's military thinking is also very advanced, but unfortunately the time is not right, the building will collapse, and he has no time to change the ending.
