Only hearing his voice but not seeing his person, Zhang Shou could also outline in his mind the image of a rebellious and domineering young man. And the voice was a bit hoarse, and it was difficult to tell his age for a while, but based on the situation at this moment,
Based on the timing and the tone of the person's voice, he roughly concluded that it was like the hoarseness of teenagers when their voices change.
If he remembered correctly, a man's voice should change between the ages of fourteen and sixteen. Of course, it can happen sooner or later, but it shouldn't be later than sixteen or seventeen at the latest. In other words, it is possible that the person who came here and
Lu Sanlang is the same age as him or slightly younger.
And after guessing like this, he soon found that he had guessed correctly. Because among the four people who walked in with their heads held high, the one at the front who looked very proud indeed looked very young, and his figure was very different from the roundness of the little fat man, but well-proportioned.
And tall and straight. If that's all it is, then that's it. While a person has an excellent figure, he also has a very pleasing round face.
This is different from Lu Sanlang. Lu Sanlang thought that he was arrogant and domineering at the beginning, but now this round-faced boy is obviously smiling, and his two small dimples are still hanging on his face at this moment.
There was just such a joyous expression on his face, which was not at all commensurate with the swaggering appearance of the person walking at the front, and it was even less commensurate with this provocative act of coming to the door.
The round-faced boy seemed to have noticed the expressions everyone was looking at him. His eyes were a little erratic. He cleared his throat before speaking: "I am Ye Mengqiu of Guangping Mansion! I know I am presumptuous in coming here today, but I heard that I am in charge of the Nine
Dr. Zhang, the imperial eunuch of Zhangtang, is here today to crown Lu Zhu, the head of Jiuzhangtang, so he came in rashly!"
"The emperor issued an edict to summon talents who are proficient in astronomy to revise the calendar. I heard that leap months will be cancelled. I dare to ask Dr. Zhang, is this true?"
Zhang Shou was speechless. He glanced sideways at the emperor and saw the emperor lowering his head and drinking the sweet rice wine as if nothing had happened. After all, this was what the banquet after the crown ceremony was supposed to drink according to etiquette. He avoided his gaze. He didn't know why.
, this nonsense rumor was spread by the emperor!
I think he was joking at the time, saying that he would change the calendar to have 365 days in a year, 135780 and twelfth lunar month with 31 days each, February 28 with 28 days, and the other months with 30 days each.
Every year, one day is added to February, and every hundred years, a trial calculation is made based on four hundred times the initial year, and the number of days in February is determined... In short, it is the Gregorian calendar. But it was mentioned once and forgotten.
Because in the era when weather forecasting was developed in later generations, the traditional lunar calendar except for the Spring Festival, Qingming, and Mid-Autumn Festival holidays, plus the waxing and waning of the moon on the lunar calendar, had few other uses. People did not need to look at the solar terms to add clothes, sow and raise seedlings.
.But in today's era, although the lunar calendar with an extra leap month is troublesome, it still has practical significance.
The emperor is simply cheating!
He didn't even know how the emperor let the news out, and what he said. He would deny it later. Now these guys came here in an aggressive manner, and if he tried to push them away, it really seemed like he was showing weakness. Therefore, he could only deny it.
After thinking about it, he smiled lightly and said, "Gao Yuan, it's up to you to do the talking."
Lu Sanlang was so angry that he had just been called by his least favorite name by a completely unrelated person. Therefore, Zhang Shou's high-pitched voice made him feel as comfortable as if he were soaking in a hot spring.
At that moment, he directly pressed the table, stood up suddenly, and shouted sternly: "The emperor re-established the calendar, so he summoned talents who are skilled in astronomy. This is a rare event since the calendar was established during the reign of Taizu of this dynasty, so it is inevitable that there will be various events."
All kinds of rumors are spreading outside, because these rumors, which are not true or false, barged into my crowning ceremony and questioned my teacher. Your Majesty is too arrogant!"
He didn't care how people came in - whether they were brought in by the servants in the Lu family who didn't like him, or by his brother and sister-in-law's instructions; or maybe his father had some kind of plan, so he deliberately allowed people to come in.
It doesn’t matter who comes in; he doesn’t even care what arrangements Zhang Shou or even the emperor have - what he cares about is the attitude of the intruder who doesn’t take him seriously!
Not taking Zhang Shou seriously means not taking him seriously!
After shouting angrily, before the other party could regain his composure, he said in a flurry: "My teacher is a doctor of Guozi, and he lectures in the East Palace. However, he is very modest. He seconded the request of Chief Yue Shan and suggested that the emperor summon all the mathematical talents in the world.
He gathered in the capital to prepare for the revision of the calendar. Even if he has a proposal, it is out of public motives and is for the emperor's reference. I have never heard of canceling leap months!"
Lu Sanlang, who was in denial, quickly glanced at Zhang Shou, thinking about canceling such a fatal matter of the leap month. Regardless of whether Zhang Shou really said it, he would help others block this issue first, otherwise don't talk to these people later.
Even the bosses in the DPRK will bombard you.
"Since the Xia, Shang and Zhou dynasties, Chinese arithmetic has emerged in large numbers, with numerous famous scholars and countless classics, naturally unparalleled in the world. From the Spring and Autumn Period, Qin and Han Dynasties to the Wei, Jin, Southern and Northern Dynasties, this arithmetic has been developing continuously. However, in the Sui and Tang Dynasties, arithmetic subjects were added to the so-called Imperial College, and even
He also decreed the Ten Books of Sutra, but in fact it was not advancing but retreating, and it was not until the Song and Yuan Dynasties that it became very popular!"
When the little fat man talked about rising, he unknowingly revealed some of what Zhang Shou had said to him when he was telling him the history of Chinese mathematics. When he said this, Ye Mengqiu, the round-faced boy who took the lead in breaking in, immediately quit.
Those words before were taught to him by a senior brother behind him. Although he knew them by heart, they were still a little awkward to say because they were not in line with his personality. But at this time, Lu Sanlang said that Sui and Tang Dynasties were not good enough, and he immediately exploded.
"The Sui Dynasty died, but there was also a famous arithmetic master named Wang Xiaotong. In the Tang Dynasty, the Ten Books of Calculation were not included in the imperial decree. When Wang Xiaotong entered the dynasty, he and Li Chunfeng were both the most outstanding arithmetic masters!"
"It's a fool's errand to imitate everyone!" Lu Sanlang didn't care that the emperor was still sitting on top, and his father, teacher, relatives and friends were all there, so he said it directly, "Forget it about Li Chunfeng, Wang Xiaotong said that Liu Hui of the Wei Dynasty was not the leader of Si Nan
, but it was also unparalleled for a while." He said, "People at the time of "Zhu Shu" said it was exquisite. I never realized that the techniques performed by Fang Yi were completely wrong and unreasonable.
"He actually had the nerve to say, 'He Xun, Xu Yue's disciples, Wang Biao, and Zhen Luan's people are all unknown. But the old scriptures are incomplete and there are still gaps. From Liu Hui onwards, there are more
It's not enough to say, "The only one who dares to love this world is Wang Xiaotong! He also boasts that he is 'searching for the secrets and reciting all the songs. He lacks close friends and ends up being alone.' Gee, why doesn't he say that he is the most powerful mathematician in history?"
Grandmaster!"
"Oh, he has already said that, otherwise he would not have written a "Ji Gu Suan Jing", so he proudly told the emperor that he asked someone to read it, and if he changed a word, he would be willing to pay thousands of gold...
Bah, his "Ji Gu Suan Jing" deliberately shows off difficult problems, which is far less profound than "Nine Chapters of Arithmetic". If you can't understand what the predecessors did, you just denounce it as ridiculous. I think it's him who is ridiculous!"
Ye Mengqiu, a round-faced boy, was caught off guard by what Lu Sanlang said. He had never had many verbal disputes with people in his life, especially those that demeaned other people's character. Even if he admired Wang Xiaotong as much as him, he could not be as good as Lu Sanlang.
Saburo always talks about people's quotations like this - especially people who hate such quotations, but he actually knows them by heart. He was even more unexpected.
Although he also felt that if Lu Sanlang had not fabricated the quotation, Wang Xiaotong, a master of arithmetic in the early Tang Dynasty, was indeed a bit too arrogant, but he still couldn't help but said: "But Wang Xiaotong's twenty questions in "Ji Gu Su Jing", how dare you call it
Can they all be solved?”
"Of course I can! If you don't believe me, just ask! With his contribution to arithmetic, is he worthy of boasting and showing off?"
Seeing the little fat man raising his eyebrows proudly, Zhang Shou couldn't help but be speechless. In order to be a doctor of arithmetic in Jiuzhangtang, although he used brand-new textbooks compiled by himself in the name of Ge Yong, in order to be a doctor of Guozi,
He also read through the Ten Classics of Calculation. Although he disapproved of the arrogance of Wang Xiaotong, a mathematician in the early Tang Dynasty, he could not deny his contribution to mathematics.
What's more, Zu's "Zhu Shu" has been lost, but "Ji Gu Suan Jing" still exists. The twenty questions are not as simple as some of the nine chapters on arithmetic, but they are smashed with a stick as soon as they come up.
You are confused - Wang Xiaotong always shows off and shows off his skills from the beginning. There are no simple questions suitable for ordinary people in the twenty questions! It is Wang Xiaotong's first to be able to use geometric methods to formulate equations!
You know, the first question in "Ji Gu Suan Jing" is to find the equatorial longitude of the moon at midnight! How many students who are good at advanced mathematics can solve this thing? Lu Sanlang hasn't learned astronomy yet.
Why is Haikou so boastful?
Next, Ye Mengqiu asked and Lu Sanlang answered, but Lu Sanlang's performance made him marvel, because Ye Mengqiu asked the first five questions of "Ji Gu Suan Jing" in one breath, and Lu Sanlang actually explained Wang Xiaotong's problem-solving ideas very clearly.
Straightforward.
Facing the little fat man's eloquent confidence and posture, even he couldn't help but touch his chin in surprise, and suddenly he felt eyes falling on his face.
He followed his gaze and saw that the emperor had a strange look on his face, while Zhu Ying next to him was snickering. He knew that the emperor must be angry and funny about Lu Sanlang's behavior.
I am asking you teachers and students to identify these talents for me, not to let you stand out!
Lu Sanlang was indeed in the limelight at this moment. Seeing that Ye Mengqiu had to jump to ask questions after the first five questions, he still answered calmly and calmly. It was not until the round-faced boy stopped talking with a gloomy look on his face that he then said "haha" in a lively manner.
A smile.
"It's not surprising that people today are worse than the past, but it would be a great shame if people today are not as good as the past! Because we eat better than the ancients and dress better than the ancients, wouldn't it be right if the things we study are not as good as the ancients? Can’t you live in the good life we have now?”
"As for whether the arithmetic calculations of small foreign countries are worth learning... Who doesn't know that my ancestor, Mrs. Ge, was most disgusted with those Arabic numerals? Even Emperor Taizu started to implement it, and it has been used all over the world for so many years. It can be regarded as in-depth
People's hearts, but the old man was always reluctant to use them at first, but once he discovered that those symbol systems were helpful in calculations, he immediately used them without even thinking about it!"
"Not only did Patriarch Ge use the Yuan books in the ancient and modern Tongji library, but they were shelved by others. It was said that Semu people in the Yuan Dynasty translated them from foreign scriptures, but they turned out to be shelved from the Yuan Dynasty to this dynasty.
He also studied them all!"
"Taking the essence of the other and discarding the dross of the other is the attitude of learning in a down-to-earth manner! Do not be superstitious about the predecessors, do not look down upon small foreign countries, and discard the junk to retain the essence. This is the attitude of a human being! Just hope that arithmetic can lead you to the next level.
Ordinary people, this is the attitude of being a teacher!"
Even Liu Shilang of the Ministry of Industry, who knew Lu Sanlang very well, couldn't help but feel that this future son-in-law was really dazzling at this moment. If it weren't for the round-faced boy who couldn't defeat Lu Sanlang, he seemed to be angry and crying
Well, if it weren't for the expressions of the elders behind him becoming more gloomy than the others, he might even have thought that this was a drama arranged by the Lu family and his son.
And seeing Lu Sanlang's performance next, he was finally further convinced that this incident was definitely not planned!
Because, after Lu Sanlang casually answered Ye Mengqiu's ten questions, he suddenly changed his tone at the end of the answer and said: "Brother, you have been questioning me for so long, is it now my turn to question you?"
?Since he is a mathematician who was called to the capital and is proficient in astronomy and mathematics, then I think you should be able to answer some simple questions easily, right?"
The little fat man smiled like a smiling Maitreya Buddha, and even clapped his hands gently. However, following his clapping, what came up were two blank... blackboards!
Ah Liu, who was delivering the blackboard, saw that Lu Sanlang looked at him with wide eyes at first, then he smiled, thanked Brother Six, took the pen from his hand with joy, then strode forward and started writing quickly.
He began to write on one of the pieces. Upon seeing this, he retreated quietly - but instead of going out, he retreated directly to Zhang Shou and stood beside him.
Faced with the scene of these two people working together in perfect harmony, Zhang Shou couldn't help but laugh: "Ah Liu, in addition to informing Lu Sanlang, you also colluded with him in advance?"
"When Master has something to do, shouldn't the disciples do the work?" Ah Liu said seriously at first, and then added, "When the disciples are in the limelight, the master is even more in the limelight."
Zhang Shou suddenly smiled. Very good, this boy who always seemed honest and honest in Rongshui Village has become more and more sinister!
As for the others, when they saw Lu Sanlang writing all over the blackboard, with symbols of dragons and phoenixes flying on them, and barely a few Chinese characters to be found, forget about the feeling of doubting life at this time. Even Lu, as a father,
Wan, as the future father-in-law, Liu Shilang, could not help but rub his eyebrows at this moment.
In the future, you must remember that arithmetic is a field that a fat guy is good at, and you must not mess with it...because you really can't afford to mess with it!
When Ye Mengqiu saw Lu Sanlang opposite him, who had a rounder face than his own, he threw away his pen and then moved the blackboard in front of him. He couldn't help but blush. As expected, Lu Sanlang took pictures next time.
He clapped his hands and then pouted at the blackboard with a proud look on his face.
"I just answered Wang Xiaotong's solution ideas and specific answers to the ten questions in "Ji Gu Suan Jing". Of course, you can also think that I memorized them wholeheartedly. And for this question now,
It's a question in the "Four Yuan Jade Mirror". I know it's difficult to solve it in three instants. Please explain to everyone on the spot how to use the Four Yuan technique to solve it."
At this point, he showed a big smile: "If you can't do it, the guys behind you can help!"
