Just after the ugly time in the afternoon, a group of well-dressed warriors riding on tall horses appeared in front of Qianhu Gate in the west of Lin'an. There were about twenty people in this group, all of them were strong and powerful, with a solemn look on their faces. The war horses under the crotch are also the best horses in a thousand. Although they are not as good as the dozen or so high-grade royal horses in Ouchi, they are extremely rare in Lin'an City.
As they approached the city gate, the group of warriors relaxed their reins and walked slowly. The leader, a tall man, reined in his horse. He looked at the word "Qian Lake" on the city gate and smiled and said: "Lin'an has arrived. "
The person who spoke was none other than the famous general Lu Wende, the Xiangfan envoy who had returned to Lin'an to attend the military reform conference.
"Yes, father, it's almost another year," said a young general next to him.
"Well, Xin'er, all the brothers, let's go into the city together,"
"Father, do you want to go home first?"
Lu Wende shook his head and said: "Xin'er, you take everyone home. I will go to the Prime Minister's Mansion to visit the Grand Master first. If I haven't come back by dinner time, you will take everyone out for a good meal so that we can enjoy Lin'an." gourmet food,"
Lu Xin said: "I understand, father."
Inside the Imperial Study Room of Funing Palace.
Wen Tianxiang sat down and said: "Your Majesty, tomorrow is the Double Ninth Festival. Whether this military reform can be carried out smoothly depends to a large extent on the attitude of the institutional commanders of the four theaters."
Lu Xiufu smiled and said: "Brother Song Rui, don't worry, your Majesty has already got it in mind."
I nodded and said: "Among the four war zones, Gao Da and Li Tingzhi should support the military reform, Lu Wende will side with Jia Sidao, and only Xia Gui's attitude is unknown for the time being. Even if Xia Gui expresses opposition, the support rate for the military reform It will also be 50%, so I don’t think it’s a big problem,”
Wen Tianxiang was still a little worried: "If Xia Gui objects, then it will be open to the public. In addition, Jia Sidao and his party will strongly oppose it. I am worried that there will be resistance."
I knew that Wen Tianxiang didn’t know Xia Gui as well as Lu Xiufu, and that he had a stable character and tried his best to be perfect in his behavior. He smiled and said, “Let’s see what we can do when the time comes. There will definitely be resistance, even if Xia Gui There will still be considerable resistance to supporting military reform. By the way, Song Rui, what progress has been made by Gunpowder Chief Yun Bofei recently?"
"Back to Your Majesty, the lathe improved by Shen Yiqiu and the others has been put into use. It uses water power as a drive. Its efficiency is much higher than that of hand-pulling or pedaling. Therefore, the production speed of muskets has also been greatly improved. Throwing bombs It is already ready for mass production. The mold of the artillery has basically taken shape, and the cannon can be tested in the next few days. At present, Yun Bofei's main focus is on the development of the musket, but he has no clue yet,"
Regarding the development of muskets, I followed the order of the invention of firearms, starting with the matchlock, then the musket, then the flintlock, the musket, and finally the breechloader.
"Firegun, musket," I muttered a few words, and suddenly remembered a story I knew about the inventor of the musket.
Among later generations of firearms researchers, some people believe that the German watchmaker John Kievers invented the musket. Kievers, who was born in the early 16th century, is quite famous in the watch industry. He can not only create various unique shapes He also had a strong interest in various firearms and made many exquisite matchlocks. One day, a guest came to the Kievers home. When the guest lit a cigarette, he did not use the popular matches at the time, but It uses the ancient flint friction ignition method. The shining sparks of the flint instantly aroused Kievers's inspiration. He combined the serrated rotating steel wheel on the clock with the flint that can produce sparks. With his experience and wisdom, , successfully developed the world's first revolving musket in 1515.
Clockmaker, by the way, I am asking Yang Xiaozhi from Lin'an University to study clocks.
Thinking of this, I said: "Song Rui, after the military reform meeting, you ask Yun Bofei to come to Lin'an University. I will introduce someone to Yun Bofei to see if he can help with the development of muskets. "
"Yes, Your Majesty,"
I practiced Shadowless Steps and Changquan in the martial arts hall for a while, then brought Yuan Ji and Xiao Qi to Shifeng Trading Company.
Although there are many things going on these days, I am still eager to meet the math master Yang Hui.
As soon as I entered the door, I saw Xiaosi stepping forward and greeting me with a smile: "Master is here, Miss Fang, Mr. Shen and the others are all upstairs,"
"Well, Xiaosi, you look good lately,"
"Thank you, Mr. Hongfu. I feel very happy here, Mr. Hongfu."
"A person who can feel happy is a kind of happiness, haha, go upstairs,"
Fang Ling saw me pushing the door open and shouted: "Brother, why are you here? We are all hungry."
"Why, Ling'er is greedy again,"
"What? I've been busy with the Red Cross these days, and I haven't had lunch yet,"
I know that after Lin Ying left, Fang Ling spent most of his time at the Red Cross. He discussed the establishment of the company with Xiao Tian and Pu Shougeng all day long: "Ling'er, this won't work. No matter how busy you are, you can't do it three times a day." You can’t skip a meal,”
Fang Ling felt sweet in her heart: "I know, brother,"
"I've met the young master," Shen Yiqiu and Quan Jue saluted together.
I nodded, my eyes fell on a middle-aged man behind the two of them and said, "This is Mr. Yang Huiyang, right?"
"Exactly," Shen Yiqiu introduced, "Mr. Yang, this is Young Master Huyan,"
Yang Hui took two steps forward, looked at me closely for a moment and said, "May I ask, Sir, was it you who wrote the "A Brief Introduction to Arithmetic"?"
"yes,"
Yang Hui suddenly took a step back, saluted me solemnly and said, "Yang has met Mr. Huyan, but he didn't expect him to be so young."
"A Brief Introduction to Arithmetic" is an outline of mathematics that I wrote based on my memory. Its coverage far exceeds that of this era. If the Yang Hui in front of me is the discoverer of Yang Hui's triangle, then he will naturally understand the preciousness of this book.
I saw that this Yang Hui had an ordinary appearance, but he was quite arrogant. He must be a person who is proud of his talent and talent: "Mr. Yang Hui, is that "Detailed Explanation of Nine Chapters Algorithm" one of your masterpieces?"
"Young master, this is exactly the work of Yang,"
"Okay, it's you after all,"
Shen Yiqiu and others were stunned when they heard this. They had the same reaction as Quanjiu last night. They thought I knew Yang Hui. I didn't explain to them and then continued: "Mr. Yang's works will be passed down through the ages." After that, I I walked to the table, picked up a hard pen and drew the Yang Hui triangle. I used Arabic numerals, which are the currently popular Xie's numerals.
Yang Hui looked at it and said, "Sir, this is what Yang learned from Mr. Jia Xian. Can you give it a name?"
"Of course, I think this can be called Jia Xian's triangle or Yang Hui's triangle. Both Jia Xian and you, Yang Hui, can be famous for future generations,"
"Jia Xian's triangle, Yang Hui's triangle," Yang Hui said after reading, "Thank you, Mr. Xie."
"Brother, let's talk while eating. Even if I'm not hungry, the guests have to eat,"
"Okay, Ling'er is right, let's inform Xiao Tian to serve the food,"
"Brother, Xiao Tian is still at the Red Cross,"
"Oh, I forgot, call me Xiaosi,"
Yang Hui finished his first glass of wine and said: "Sir, this Xie's number is a major innovation in mathematics this year. This method of recording is indeed much more convenient. I didn't expect that there is such a person in the palace. I must pay him a visit if I have the opportunity. "
I smiled and said, "Mr. Yang, in your book "Detailed Explanation of the Nine-Chapter Algorithm", you compiled the number table I just drew and called it the 'Origin of Square Root Method' diagram. This table also expresses The rules of the quadratic term coefficients of each term after opening the brackets of a polynomial,"
"Exactly, Young Master has read Yang's Nine Chapter Algorithm,"
"I have seen a small part and have a rough idea,"
Shen Yiqiu on the side said: "Young Master, the university is planning to recruit Mr. Yang Hui as a professor in the Department of Mathematics, but the mathematical attainments of the people in the university are not as good as Mr. Yang Hui's, so I still ask for your guidance on this title."
"This is simple, Mr. Yang is talented enough to be a master,"
"Master," Shen Yiqiu and Quan Jue blurted out together, and even Yang Hui himself was a little stunned.
I said without hesitation: "That's right,"
You must know that there are very few masters at the level of master. In Lin'an University, only He Ji and Shen Yiqiu were awarded the title of master, and Yun Bofei from the Gunpowder Department. The rest, such as Song Wuxin, Huang Daopo, etc., were only awarded the title of master. It is a guru. Although there is only one word difference between guru and master, they are completely different realms.
Seeing how determined I was, Shen Yiqiu said, "Yes, young master."
Fang Ling took a sip of tea and joined in the fun: "Brother, look at Ling'er's level of martial arts."
"This needs to be evaluated by Mr. Yuan,"
Yuan Ji said: "You can be called a guru."
Fang Ling smiled and said: "Haha, I am also a guru,"
I said: "Mathematics is a science that studies numbers and shapes. It is the foundation of any science. Natural sciences such as physics and chemistry are inseparable from mathematics. Mr. Yang Hui, although your attainments in the field of mathematics can be called It is the realm of a master, but I hope you can make greater contributions,"
Yang Hui had already put away his arrogance: "Master, please make it clear."
"Mathematics covers a wide range. This subject will be collectively referred to as mathematics from now on. It can be roughly divided into algebra, functions, trigonometry, geometry, derivatives, integrals, differentials, etc. Sir, you focus on computing technology. Have you read my "A Brief Introduction to Arithmetic", the above content is what should be covered in the field of mathematics. Of course, I am not saying that you should be proficient in everything by yourself, that is impossible. What I mean is that I hope that Mr. Yang, you can become our leader in mathematics subjects. leader,”
"Yang understands, but I just want to ask the young master for more guidance,"
I understand what Yang Hui means, but I only know a little bit about these: "Mr. Yang, I have not done any special research on mathematics. The brief arithmetic I wrote, including the brief physics and chemistry briefs I wrote, are just To carry forward the conceptual content, we have to rely on you elites in each subject,"
Yang Hui looked at Shen Yiqiu in surprise and asked: "What, a brief summary of physics and chemistry was also written by Mr. Hu Yan,"
"Exactly," Shen Yiqiu said with a smile, "Sir, if it weren't for these brief chapters, Mr. Yang Hui wouldn't be willing to come to see you."
Yang Hui's face suddenly turned red and he said: "Yang is a frog in the well, sir, please forgive me."
Seeing his embarrassment, I quickly interrupted with a smile: "Mr. Yang, do you have any suggestions for Lin'an University?"
"Sir, Lin'an University's establishment of a new learning culture in our dynasty is indeed a great initiative, but Yang feels that the people who founded the university seem to be too stingy,"
When Shen Yiqiu and others heard this, they felt unhappy.
"Well, what do you mean," I asked curiously, while signaling Shen Yiqiu and others to stay calm.
Yang Hui didn't seem to notice the difference in the expressions of Shen Yiqiu and others, and said: "Sir, think about it, I have tens of millions of people, but there are only twenty students in this mathematics department. Isn't this stingy?"
I laughed in surprise and said: "Haha, Mr. Yang, this is not stingy. It is actually because it is difficult to find professors in the school. It would be great if Mr. Yang comes. I guess there must be a solution."
"Sir, Yang has nothing to say about other subjects, but in the Department of Mathematics, Yang can guarantee that there will be no problem in hiring three or five capable mathematics professors,"
I was about to continue talking when I saw Xiaosi hurried upstairs to report: "Sir, a group of unknown people are causing trouble in Tongle Building."
