After the news in the "Datang Daily" reached the Imperial College, it once again caused an uproar, especially in the Arithmetic School, causing an unprecedented shock.
Because Li Zexuan "resigned" in anger, he not only "took" away all the students in the Mathematical School, but also "poached" Xu Hongzhi, the original teacher of the Mathematical School. The Mathematical School once fell into a situation where there were no teachers and no students. embarrassing situation.
In desperation, Kong Yingda personally came forward and invited Liu Hongyuan (Xu Hongzhi's mentor), a former Ph.D. in mathematics who had been living at home, to come out again, and selected a group of students from various prefectures to supplement them (after all, these days, students who are willing to go to the Imperial College still account for only a small portion of the total). Although the Yanhuang Academy is now very famous, its reputation among the people is still not as good as that of the Imperial Academy, the first official school in the Tang Dynasty), and the Arithmetic Academy resumed normal teaching!
It is worth mentioning that the enrollment scale of the School of Mathematics has approximately doubled compared to the previous one, with a total of 71 students enrolled. It seems that it wants to compete with Yanhuang Academy in the field of arithmetic.
In addition to recruiting more students, Kong Yingda also hired three teaching assistants for the Mathematical School to help Liu Hongyuan teach the Mathematical School. Therefore, today's Mathematical Sciences Center is more than one level higher than before in terms of both the number of students and the number of teachers!
In the arithmetic library.
"Hey, have you heard? Marquis Yong'an made a simple needle throwing game, and you can easily calculate the approximate value of the ancestral rate. It's amazing!"
"I have read the newspaper, but I think this must be a coincidence, right? After all, whether the needle is pressed or not is completely determined by luck. The fact that he finally got such a result depends entirely on luck!"
"I also think it's a coincidence! If he does it again, the result will definitely be different!"
"I don't think so! Since Marquis Yongan dared to publish this experiment in the "Datang Daily", he must have been prepared to be questioned! In other words, this experiment can withstand questioning!"
"By the way, why hasn't Mr. Liu come yet? At this time in the past, he should have come long ago!"
"Mr. Liu is here, Mr. Liu is here!"
Just as the students were talking about each other, an old man in coarse white clothes came in from the door. Matched with his gray hair, he looked inexplicably aged. The old man was followed by three middle-aged scribes, all of whom deliberately stayed half a step behind the old man to show respect. The classroom, which was noisy just now, suddenly became quiet.
"Haha! I just heard you guys talking about the needle experiment in the newspaper outside. You must all want to know whether the result in the newspaper is a coincidence, right?"
The old man stood on the podium, looked at the students below and laughed.
This old man is Liu Hongyuan. He has already reached the age of retirement but was invited back. After spending more than ten years in the Imperial College of Computer Science, he still feels a little reluctant to leave this place!
No students responded. Because they had been in the Imperial College for so long, they all knew that most of the teachers in the Imperial College didn't like students talking about things related to Li Zexuan. This was already a tacit truth.
Although they could not make a sound, the students looked at Liu Hongyuan with bright eyes.
Liu Hongyuan had no prejudice against Li Zexuan. On the contrary, he had bought a copy of Li Zexuan's new arithmetic textbook and studied it. Seeing that the students looked like they wanted to say something but did not dare to say it, he smiled and said:
"In fact, not only you want to know, I also want to know whether the results obtained by Marquis Yong'an are a coincidence. Before class, I prepared a piece of paper with engraved lines and a pack of fine needles. The distance between the engraved lines and the needle The length is exactly the same as what was described in the newspaper. So today our math center will do a needle experiment to see if the result in the newspaper is a coincidence~!"
As Liu Hongyuan spoke, he took a gray cloth package from a teaching assistant. Inside was a piece of rice paper with lines drawn on it and a pack of fine needles. The reason why he was late for class today was to prepare these two things!
When the students heard this, they couldn't help but started talking privately.
"Wow! Are we going to do a needle experiment too? Mr. Liu is so enlightened!"
"Hey! If it can be proven that the results in the newspaper are a coincidence, won't our math school become famous this time?"
"Haha! In my opinion, it's probably a coincidence!"
"Haha, I don't think so!"
Liu Hongyuan patted the table and signaled the students to be quiet, and then he said: "We have a total of seventy-one students in the Mathematical School, which is still a bit small. In order to match the total number of needle experiments in the newspaper, you will follow the order in a moment Come up and throw the needle, each person throws it ten times, be careful not to use too much force, and throw the fine needle out of the paper. Three gentlemen and I will help you count the number of times the fine needle presses the line. Yao Yuanhe, come up, from your side Start~!”
After that, Liu Hongyuan spread out the rice paper and gave instructions to a student sitting at the door.
"Yes, Mr. Liu!"
The student responded and ran up very excitedly.
The other three teaching assistants stood behind Liu Hongyuan with paper and pens in hand, ready to take notes.
The verification experiment of the needle throwing experiment was officially launched at the Imperial College of Computer Science.
The whole experiment lasted for more than half an hour before it was over. Since it was a real-time calculation, once the thin needles thrown by the students pressed the line, the teaching assistants immediately counted them. Therefore, not long after the experiment ended, the final results were calculated. .
Liu Hongyuan took his statistical results and checked them with the three teaching assistants. After finding that the results were all the same, he turned to the students below and said: "We have a total of seventy-one students, each of whom voted ten times. That means you just voted in total." I cast seven hundred and ten times, and according to the statistics between me and the three gentlemen, the fine needle pressed the center line a total of two hundred and twenty-six times~!"
As soon as he finished speaking, a student with a better memory immediately exclaimed: "Seven hundred and ten, two hundred and twenty-six, the results in the newspaper are seven hundred and thirteen, two hundred and twenty-seven! Our The result is so close to the one in the newspaper~!”
"Wow~!"
The whole class of students immediately burst into an uproar.
The three assistant teachers on the podium also had expressions stagnant, because at this time, they also recalled the data in the newspaper.
Liu Hongyuan's expression remained unchanged. He turned around, picked up the chalk and started calculating on the blackboard. Upon seeing this, the students quickly stopped talking and watched Liu Hongyuan's calculations quietly.
When the calculation reached seven decimal places, everyone's expressions became brighter, and Liu Hongyuan, who had always been calm, was no exception. The old gentleman was so excited that his whole body was trembling. The chalk in his hand fell off and he couldn't feel it anymore. He murmured to himself:
"What a miracle! I, I actually calculated the sixth decimal place of Zu rate...this..."
