Into Unscientific Chapter 136

  Chapter 136 is not just as simple as Han Gonglian

  Han Gonglian?

  Hearing this name, Xu Yun's expression froze for a moment.

   Didn't expect, ah, didn't expect.

  The candidate given by Lao Su.

   It was him?

  Han Gonglian.

   This is a mathematician with little information left in the Northern Song Dynasty. Later generations don't even know his name.

  Only in his birthplace "Guping County Strange History", there is a little information about his self-named Mr. Yang Huai.

   After all, the account these days is similar to the nickname of station B in later generations, and anyone can take it.

  In addition to those well-known users, there are only a few ordinary people who can be recorded.

  However, only from the surviving few words, future generations can still easily judge Han Gonglian's ability.

   Song Yuanyou first year.

  Han Gonglian served as the official of the Ministry of Officials, and his rank was the lowest rank of Zhengjiu.

  At that time, Lao Su took office as Minister of the Ministry of Officials, and was ordered to inspect the armillary sphere used by the Taishi Bureau and others, and prepared to make a new one.

   As a result, during the visit, Lao Su heard that Han Gonglian was proficient in mathematics and astronomy, and he was counting everyone in Bianjing.

  Lao Su came to the door in person and told the outline of the instrument procedures of the previous generation of astronomers Zhang Heng, Liang Lingzan, Zhang Sixun and others. .

  I hope he can get to the bottom of it and imitate it accordingly.

  Han Gonglian wrote a volume of "Nine Chapters of Pythagorean Examination Huntian Book" for this purpose, and made a wooden mold of a machine wheel.

   After reading it, Lao Su thought that although it was not quite as the ancients said, the design of the water transport wheel was unique and highly feasible.

   Therefore, this plan was selected, and it was submitted to the imperial court and approved.

   Yuanyou two years.

  Han Gonglian was appointed as the system officer and began to make Xinyi.

   Yuanyou seven years.

  The instrument was finally completed and was named Yuanyou Armillary Sphere.

  At the same time in history, Han Gonglian is also considered to be the most critical figure in the production process of Yuanyou armillary sphere image, besides Lao Su.

   So it can be seen from this.

  Although Han Gonglian's writings in history books are not many, his ability in mathematics is obviously much higher than that of ordinary people.

   From a certain point of view.

  He is actually very similar to a Portuguese player named Eder in later generations.

   He was unknown before, and his name was hardly heard of by everyone, and he never played much.

   As a result, he came off the bench in the 2016 European Cup final, sealed his throat with a sword to help Portugal win the championship, and then fell silent again after the incident.

no way.

  Although mathematics in the Song Dynasty developed very rapidly, the feudal dynasty was ultimately dominated by personnel struggles.

  Many mathematicians don't have many opportunities to show their talents, let alone be recorded in the history books.

Of course.

   Although the truth is such a truth.

  But if he is really the kind of top-notch mathematician, he should be able to leave some records in the history books more or less.

  For example, Qin Jiuzhao.

  For example, Yang Hui.

   Another example is the man who abducted Nobel's wife, well, this doesn't count.

  So let's say a more objective positioning:

  Han Gonglian should be the kind of advanced, even close to the top talent in mathematics.

   But the distance from the 'ceiling of the times' may still be a little far away.

   So Xu Yun thought about it.

   Still going to ask Lao Su again to see if he can find more talents like Han Gonglian.

   After all, the calculation workload this time is still quite large, and the eggs can't just be put in one basket:

   "Master, according to what you said, Mr. Yang Huai is obviously a pretty good candidate.

  However, the calculation steps required by the astronomical telescope are extremely complicated, and it may take time and effort for one person alone.

   Therefore, if the master still has candidates, he might as well find a few more capable people to help, which can be regarded as a precautionary measure. "

  Old Su nodded as he listened, and seemed to accept the suggestion.

  He had seen Xu Yun tinkering with generators and electrolytic cells, and he knew that some knowledge of Fenglingyueyingzong was extraordinary.

   I am afraid that it is somewhat different from the existing cognition, and may even need to refresh the inherent cognition.

  If only Han Gonglian was invited, it would be fine if the other party could understand axiom.

  But if there is a lag or doubt.

  Then the "recovery" process of the entire astronomical telescope is likely to be delayed or even stagnated.

   Then he thought carefully about the mathematicians he knew, and after half a minute, his eyes suddenly lit up:

   "Xiao Wang, can you roughly describe the arithmetic knowledge you mentioned in words?"

  Xu Yun glanced at him a little strangely, and was a little puzzled about Lao Su's purpose, but he still nodded:

   "It's not difficult. After all, the villain read the content from the book. It's easy to outline some key points."

  Old Su saw that he waved his hand and said excitedly:

   "That's very good, later you will follow me to the study, write a letter, and send it to Ying Tianfu.

   There is a current counting master who lives in a hut in the countryside of Fuzhong. If he can be persuaded to come to Bianjing to help, the mirror accuracy will be counted! "

  Seeing Lao Su who showed such excitement and admiration for the first time, Xu Yun suddenly became interested:

   "I don't know who it is?"

  Old Su was silent for a moment, organized his words, and said with a little reverence on his face:

   "This person's surname is Jia Mingxian, and he studied under the master of Jiuzhang Pushing Chu Yan"

  Before Lao Su finished speaking, Xu Yun's eyelids twitched violently.

  Mom.

   It was Jia Xian?

   This monumental figure in the history of ancient mathematics is still alive at this time?

   Talk about a well-known mathematician in ancient China.

   The first thing that comes to many people's minds is probably Zu Chongzhi.

   That is, the first man in the world to actuarially calculate pi to the seventh decimal place, more than a thousand years earlier than Europe.

  But apart from Zu Chong, Huaxia has many good people in mathematics.

   And can be divided into many categories according to their contribution and direction.

  For example, in terms of influence on modern mathematics, Qin Jiushao is undoubtedly the most recommended.

  Because in local mathematics, only his Dayan Derivation and Chinese Remainder Theorem are still preserved by modern mathematics.

  The rest of the various ancient Chinese mathematical techniques and mathematical tools were all reinvented by Western mathematicians.

  If it is epoch-making pioneering.

  There is no doubt that Liu Hui and Zhu Shijie are the first to be recommended, because they correspond to two huge leaps on the two peaks of mathematics in China:

  Liu Hui sorted out the mathematical knowledge of the entire Qin and Han Dynasties, established the overall framework of ancient Chinese mathematics, and summarized the overall calculation framework of linear algebra.

   is roughly similar to Euclid in Greek mathematics.

  Zhu Shijie sorted out the mathematics from the Tang and Song Dynasties, standardized the mathematical framework of Tianyuanshu, and brought Huaxia's algebra from unsigned calculations to signed calculations.

   In the triangle field, Jia Xian is undoubtedly the best of the best.

   Remember the Yanghui Triangle mentioned in the 1665 copy?

  Yang Hui Triangle was actually proposed by Jia Xian, so some people will call it Jia Xian Triangle.

  However, due to the loss of his works, his excellent ideas were recorded by another great mathematician, Yang Hui.

  That is why later generations defined this law in the name of the Yang-Hui Triangle.

  The reason given by the Asian Mathematical Congress in 2011 is that Yang Hui's record has physical evidence, and there is nothing wrong with this logic.

in addition.

  Jia Xian also created the square rooting methods of "Increased Multiplier Kaiping Method" and "Increased Multiplier Kaiping Method",

  It is a kind of efficient method to find the numerical solution of higher degree equation.

   That's right.

   Find the value of the higher degree equation.

To know?

  Really in Europe, "Roman Numerals" are still being used.

  That's right, numbers, even table numbers are very difficult, let alone such complicated square root calculations.

  The calculation procedure of Jia Xianzeng's multiplication-opening method is roughly the same as the method of the European mathematician Horner (1819 AD), but it is 770 years earlier than the other party.

   And this is precisely an important link in the calculation of mirror surface precision, and there are still many derivative calculation formulas to be solved.

   That is to say.

   Whether it is from the perspective of ability or professionalism, Jia Xian is a more suitable candidate than Han Gonglian.

but in the meanwhile.

  He is also a character outside of Xu Yun's plan. Xu Yun didn't consider him at all from the beginning.

  Because the time of Jia Xian's birth and death is also unknown to later generations, but most people think that he died before Song Huizong came to the throne.

  According to the records of "Song History·Yiwenzhi".

  Jia Xian completed the "Nine Chapters of the Yellow Emperor's Computational Classics and Fine Grass" around 1050, when he was in the position of Zuoban Dianzhi.

  Zuoban Dianzhi is one of the three classes, and is a ninth-rank official.

  According to the comparison table of Song Dynasty official positions and ages collected by later generations, Zuoban Dianzhi is generally held by adult men aged 25-35.

  At the same time, Wang Zhu wrote a sentence in "National Court Meeting":

   "The constitution is now Zuoban Dianzhi, Jili Taishi. The constitutional calculation is also wonderful, and there are books handed down to the world."

  Wang Zhu wrote "Guochaohuiyao" in 1043, and it was completed in the autumn of 1045.

   That is to say.

  In 1045 AD, Jia Xian was at least 25 years old.

  It is now AD 1100, and a good 55 years have passed.

  If Jia Xian is still alive, he is guaranteed to be 80 years old, maybe even 90 years old or older.

  Although Lao Su is also eighty years old, who is he?

  The former prime minister!

  Whether it is the material level of life or the level of medical treatment enjoyed, it can be said that there is no one in ten thousand, or even one in a million.

   But Jia Xian was just an ordinary official, and he resigned not long after.

  In terms of material living standards, it is far lower than that of Lao Su, at most the level of a small landlord, maybe not so rich.

   Therefore, in the mathematics circles of later generations, most people believed that Jia Xian had passed away when Song Huizong came to the throne.

  Even the entry encyclopedia defines him as "an outstanding mathematician in the first half of the eleventh century".

  It can be seen right now.

  Jia Xian is still alive?

   And according to what Lao Su said.

  If Jia Xian can be persuaded, he may even rush over from Yingtian Mansion!

  Ying Tianfu is the Baixia of later generations, and Bianjing is Junyi.

  The distance from Baixia to Bianjing is more than 600 kilometers, and it will take three hours by train in later generations. In ancient times, it was considered a long distance.

  So it can be judged from this.

  At present, Jia Xian's physical condition may be quite good, otherwise, he would not be able to withstand such a long journey.

how to say

   Although quite surprising, this is undoubtedly good news.

   After all, Xu Yun's goal is not just as simple as an astronomical telescope.

   Some things are not like astronomical telescopes. They say they can't calculate them, but in fact they can calculate them easily with their own abilities.

  The computing power of those things is completely difficult even in terms of Xu Yun's personal ability, and it must be done with external help.

  So facing Lao Su's proposal, Xu Yun agreed on the spot:

   "Mr. Tongyu has been friends with a villain for a long time. If he can help him, the telescope can be accomplished!"

  Later, Lao Su and Xu Yun mentioned a few more names, all mathematicians who were unemployed and stayed in Bianjing or around 20 or 30 miles away.

   Among them, one or two Xu Yuns have heard of their names, and they are much inferior to Jia Xian and Han Gonglian in terms of ability, and they can be regarded as the type of high-level talents.

   And more are the names of people who have never been heard of in later generations. The ability is unknown, but it is estimated that it will not be very high:

  After all, Lao Su needed a lot of mathematical calculation support when making the new instrument. At that time, he basically searched for mathematicians in Bianjing, and he still has a deep understanding of the entire Bianjing mathematics circle.

  Unless they are some rising stars, the ability is obviously not too strong.

   Now that things have come to this point, today's class is naturally almost over.

  Later, Old Su thought about it, and happily said to Xiao Zhao and Xiao Li:

   "His Royal Highness Jian Wang, Qingzhao, why don't you go after the dinner at the residence?"

  Xiao Li and Xiao Zhao looked at each other, and declined aloud:

   "Young master is loved, but I still need to go back to the palace as soon as possible to find the master craftsman. After all, you know my elder brother, so let's do it next time, definitely next time."

  Looking at the riddleman with the face of "you understand", Xu Yun blinked in confusion.

  As a non-history science major, he naturally doesn't understand.

  In the short period of time after he took the throne, Song Huizong had already shown a little fan of the emperor of flowers and birds:

   Spend at least three hours a day drawing and writing, and occasionally it may be changed to kicking Cuju or having sex.

  My younger brothers wanted to see him, but they could only be granted at Shen Shi in the afternoon.

Of course.

   What he said to Queen Mother Xiang was that he liked to review memorials alone, and that Queen Mother Xiang died early, so he was really deceived by Song Huizong before his death.

   Zhao Ji dared to do this when the Empress Dowager Xiang, the low-profile version of Cixi, was still alive, but when Jin Jun came, he was discouraged, which is quite ironic.

  Later, Lao Su went back to his study to prepare a letter for Jia Xian, while Xiao Li and Xiao Zhao handed it to Xu Yun to see them off.

   After all, the current Xu Yun is both a "teacher" and a guest, and he is enough to send Xiao Li and Xiao Zhao off in terms of personality.

  Lao Su's mansion is not very big, and the class of several people is in the front yard, only a short distance from the gate.

   After walking for a while, the three of them arrived at the door.

   "Prince Wang."

  Before parting, Xiao Zhao took the initiative to bow to Xu Yun:

   "The ancients said, listening to your words is better than reading ten years of books.

  What Young Master Wang said today really made this king suddenly enlightened. I am afraid that I will never forget the theory of gravity and planets in this life. "

  Xiao Zhao's expression and tone were very sincere, and what he said was from his heart, not polite words.

After all, if he hadn't been interested in science, he wouldn't have followed Xiao Li to Lao Su's mansion to meet Xu Yun—at that time, Xiao Li didn't know that Xu Yun had been promoted, and the prince met the servants. The concept of handing over.

   And the other side.

  Xu Yun also has a good impression of this handsome man. Every time he sees him, he seems to see the same handsome master reader:

   "His Royal Highness Jian Wang is too praised, the villain is just transcribing the contents of the manuscripts written by the sages.

  Just like the teaching of elementary school, preaching the books of sages and sages can be done by another person.

   What should be admired is the wisdom of the sages, which is as vast as the sea of ​​stars, but I don't know how many of them have been buried in the time. "

  Xu Yun's words seemed to touch Xiao Zhao's heart, and he also sighed and said:

   "That's true. If the prince hadn't mentioned it, I'm afraid I wouldn't know until my death that there is such a mysterious sect as Fenglingyueyingzong in the world.

  By the way, Young Master Wang, you are the only one left in the Fenglingyue Shadow Sect? "

  Xu Yun heard the words, a trace of sadness flashed in his eyes, and his face showed bitterness and heartache:

   "The Fenglingyue Shadow Sect has long since dissipated in the years, and the villain is just lucky, and by chance, he has been passed down from generation to generation.

  Like an astronomical telescope, many inheritances have long been fragmented, and my descendants only hear their names, but not their objects, alas."

  Xiao Zhao shook his head sadly, then he coughed lightly, comfortingly said:

   "Prince Wang, people must look forward, and don't talk about sentimental words anymore.

  As for the artisans and property matters, I will definitely take care of them after returning to the palace, and strive to restore such a miracle as the astronomical telescope as soon as possible! "

  Xu Yun nodded, subconsciously trying to persuade His Highness King Jian to move out of the palace.

  However, considering that it is not appropriate to talk lightly and deeply, in the end, I can only turn into a cloud of turbidity in depression.

   Then he looked at Xiao Li at the side again, and smiled a little:

   "Miss Li, let's say goodbye for today."

  At this time, Xiao Li was drooping his brows, and waved to him a little depressed:

   "I'm sorry Wang Lin, I can't help you with the astronomical telescope this time"

   "Hey, what's this?"

  Xu Yun made an indifferent gesture towards her, and said with a smile:

   "Miss Li, don't worry, we have a lot of time, maybe the next chapter. Ahem, I will trouble you next time!"

  Xiao Li still nodded his head in a daze, and soon thought of something.

  With a little expectation and nervousness, he said to Xu Yun:

   "Wang Lin, when the astronomical telescope starts to be made, can I still come to the bladder?"

  Xu Yun nodded heavily, and readily agreed:

"sure."

  Xiao Li saw that he regained his energy and let out a sigh of relief.

   After all, although the status of women in the Song Dynasty was not low, a girl who was not out of the cabinet mixed with a bunch of old men still challenged the inherent concepts.

  Xiao Li herself is not worried, but her father, Comrade Lao Li, has already resigned to his fate.

   Therefore, the biggest obstacle in the whole thing comes from Xu Yun and Lao Su.

   After all, scholars think of themselves as noble, and people like Lao Su are even more afraid of not being safe at the end of the year, and they might try to reject themselves.

   Seeing that Xu Yun personally agreed to let him watch a wave of telescope production, it also represented the lifting of the biggest obstacle.

  Then the three of them said a few simple words of courtesy, and then they parted outside the door.

  Xu Yun followed the courtyard and returned to the East Wing.

  He planned to take a rest for a while, and by the way, summarize the knowledge points he was going to write to Jia Xian.

  If there is still time.

   Then think about how to go next.

   As a result, he walked to the edge of his own courtyard, but hadn't entered the courtyard gate yet.

  He saw Wang Zhi, a cold-faced man, embracing his arms, standing at the gate of his courtyard like an iron tower.

  See this scenario.

  Xu Yun was subconsciously surprised:

   Could it be that Wang Yue is in trouble again?

   After all, it was only through the period when the possibility of accidents was the greatest, and it was far from being completely out of risk.

  In the Song Dynasty, where the medical environment was not complete, accidents could happen at any time after the injection of antibiotics.

  So he quickly stepped forward, bowed his hands to Wang Tin, and said eagerly:

   "Master Captain, have you come to the villain? Could it be that Zhonghou's condition has changed?"

   Seeing Xu Yun worried about Wang Yue, Wang Bao's heart suddenly warmed up, and he waved his hand with a smile:

   "Xiao Wang, don't worry, your brother is in good condition. Wang is here mainly for you."

  Xu Yun was taken aback, and pointed at himself with his index finger:

"I?"

  Wang Jin nodded, and took out a few thread-bound books from his body:

   "If it wasn't for you, Xiao Wang, Wang and his elder brother would have been separated from each other at this time, and there would be no repayment for saving their lives."

   "Wang Mou thought about it this morning, and suddenly realized that your figure seems a little thin, so."

   "Here are a few martial arts cheat books. Although they are not high-level martial arts, they can be quickly learned in a short time. Are you interested?"

Note:

  6600 words are here, all night till now, there are more tonight!

   This month, the minimum guarantee is 200,000. If you do what you say, ask for a monthly pass!

   First of all, there is no charge for writers, no charge, no charge!

   Some readers have reported that there are a lot of character introductions and science popularization recently. Let me explain here.

   Recently, these episodes have reached a number that is quite surprising to me, and is the highest ever for this book.

   This can be seen from what is said in this chapter, which shows that everyone should like or accept this kind of plot.

   The second is that every character that takes a long introduction will be of great use later on. I won't spoil the details. I really want you to see it tomorrow.

   The last big chapter asks for a monthly pass!

  (end of this chapter)
