Settled in the Tang Dynasty

Chapter 389 On Education

Xue Lang planned to write this math book as a series.The first volume is very simple, it is written with reference to the first volume of elementary school mathematics, and it is mainly to popularize basic knowledge.Therefore, in the eyes of adults who already have a foundation in mathematics, this book is very simple, and it is naturally quick to read.

Qin Wang flipped through it quickly, holding the "Foreword" written by Xue Lang in his hand, thinking silently.Princess Pingyang took the rest of the paper and flipped through it. Afterwards, the sage and King Qi all read it.King Qi said: "Sister...what is the purpose of brother-in-law writing this book? It seems too simple?"

King Qi called Xue Lang awkwardly, and looked at Princess Pingyang after calling, Princess Pingyang smiled indifferently, didn't say anything, and didn't show any strangeness, Xue Lang found that King Qi seemed to be quietly relieved... Cough cough, poor child!

Lighting the candle for King Qi in his heart, Xue Lang smiled on his face and said, "Because this book is for enlightenment, naturally it can't be too difficult."

"I see."

King Qi didn't ask any more questions.After reading the foreword manuscript in his hand, King Qin handed it to the sage, and asked: "It is written in Youyang Book that mathematics is the foundation of all subjects. I don't know how to explain it?"

Xue Lang said: "If we want to explain this sentence, we must start with the division of disciplines. In the flower planters, disciplines can be divided into two major subjects, liberal arts and science. Under these two major subjects, there are subdivided into smaller ones. Subject……"

Xue Lang started from the division of subjects, first explaining roughly which subjects there are, and how mathematics can play a role in promoting it.After finishing speaking, Xue Lang said: "...It can be said that a person's life, from the time he falls to the ground, until he is an octogenarian, is all about dealing with mathematics. The date of birth, weight, etc. are all calculated using mathematics. The age of longevity is also calculated by mathematics. Mathematics is closely related to a person's life."

Everyone nodded in agreement.Xue Lang said: "This is the aspect of life. In other affairs, it is necessary to use mathematics to calculate taxes from the state, build bridges and pave roads, and go down to the salaries and salaries of officials and soldiers. Astronomy and calendar, geography, and knowledge of things can all be calculated with mathematics." to calculate. That’s why it is said that mathematics is the foundation of all subjects.”

After a pause, Xue Lang continued: "Actually, if we talk about the study of mathematics, the Ten Classics of Mathematical Sciences has already done a good job. The depth and breadth of the research are sufficient. It can be said that it is much ahead of other places in the world at the same time. There is an examination and selection for the subject of mathematics, and there will only be more people who study mathematics. Although the ten classics of mathematics emphasize examples rather than theory, compared with the wisdom of the ancestors, the knowledge of mathematics I have learned cannot be called superior. It’s just that the calculation method is more convenient. Therefore, I want to write such an enlightenment mathematics book to make up for the shortcomings of existing mathematics books.”

Xue Lang explained his thoughts clearly, and the sage and King Qin nodded in unison.Qin Wang asked: "This year, the calculation and statistics of the Ministry of Finance have been completed faster than expected, is it because Youyang uses the method of digital calculation?"

"Yes. I asked someone to make two large wooden boards, and used the leftover charcoal sticks as pens to calculate on the wooden boards. Compared with the calculation, it is easier and faster, so the calculation efficiency can be improved."

The sage asked strangely: "This year, the official affairs of the Ministry of Civil Affairs are completed as in previous years. Is there any advance?"

King Qin said: "Father, during the summer harvest in previous years, the Ministry of Civil Affairs would have to work hard all night for a few days, but this year it didn't. I think it must be due to Youyang."

As for the completion date, it is not surprising that it is the same as in previous years.The requirements of the people above will only get higher and higher.Pei Ju is sophisticated and old, so he is naturally not the kind of person who is eager to show off and take credit for embarrassing his subordinates, so he has room for doing things.The sage thought about it for a while and then understood that this is human nature, so he waved his hand and skipped it.

Speaking of mathematics, the sage said: "I once heard Pingyang say that the reason why you are so knowledgeable, Youyang, is related to the school system of the flower growers, right?"

Xue Lang said: "I am ashamed of the erudition spoken by the sage. However, when it comes to the education system of flower growers, there are merits. The education system of flower growers starts at three years old, goes to kindergarten, and starts elementary school at six years old. It takes six years, three years in junior high school, three years in high school, and four years in university. Before university, everyone took the same courses, and after university, they began to divide subjects into more specialized and in-depth studies.”

The sage counted and said, "Then don't you have to go to school until you are weak?"

Xue Lang said: "Returning to the saint, yes. Therefore, I have never been to university, and most of what I have learned is from books or specially taught by teachers. What I learn is complicated and not as profound as a professional university. However, although this school system Good, but Datang is not applicable."

The King of Qin said: "What Youyang said is very true. I was established at the beginning of the dynasty, with limited taxes and the world is not yet peaceful. Military pay is the largest expenditure. Therefore, although this strategy is good, there is no capital to implement it."

Xue Lang nodded and said: "As Erlang said, education can only be led by the state. However, one is limited by money, and the other is limited by teachers. To develop education, the two lack One must."

Of the four ancient civilizations in the world, only China has been handed down, which is inseparable from the Chinese nation's tradition of emphasizing education and inheritance.Because of such customs, there is the inheritance and continuation of civilization from generation to generation.When China was poor and poor in later generations, one policy contributed to the development of education, that is, the free policy for normal students, which cultivated many teachers needed for compulsory education.

In fact, the teachers trained in this way are not enough. In many remote areas, those who graduated from high school and junior high school cannot enter university, and many people have become substitute teachers.

Everyone knows the importance of education, however, conditions are limited.The situation in the Tang Dynasty at this time did not allow such a policy to be implemented at all.

Everyone here is not a fool, even King Qi can understand the pros and cons of it.The sage sighed and said: "Governing a big country is like cooking a small fish. There are thousands of threads. Although I have ambitions, the conditions are limited. Not all good policies that benefit the country and the people can be implemented. It is really a great pity in life! Entrepreneurship It is even more difficult to maintain a career, and now that the country has been established, what happens in the future depends on future generations."

"Son, lead the training!"

Except for Xue Lang, King Qin, King Qi, and Princess Pingyang all knelt down.Xue Lang looked left and right, then knelt down as well, which made the saint laugh, and the gloom dissipated in an instant, and he asked with a smile, "Youyang, why are you kneeling?"

Xue Lang scratched his head silently in his heart, and said: "I will also work hard and help the saint wholeheartedly."

The sage laughed, got up and pulled him up, and praised him: "It's good if you have such a heart."

Next, everyone discussed Xue Lang's mathematics book together, and they all agreed that it could be finalized.Seeing this, Princess Pingyang asked someone to pick up the manuscript and take it back to Chang'an, so that the printing house under her name could print it.
