Otaku Engineer in Great Tang Dynasty

After the news from the "Datang Daily" reached the Imperial College, it caused another uproar, especially in the School of Mathematical Sciences, which caused an unprecedented shock.

Because Li Zexuan was angry and "resigned", not only did he "take" away all the students in the School of Mathematical Sciences, he also "digged" away the husband of the former School of Mathematical Sciences, Xu Hongzhi. Awkward situation.

In desperation, Kong Yingda personally came forward and invited Liu Hongyuan, the former doctor of mathematics (Xu Hongzhi’s mentor), who had been at home again, and selected a group of students from the prefectures to add in (after all, the students who were willing to go to the Imperial College this year still accounted for Although the Yanhuang Academy is now well-known, its reputation among the people is still not as good as that of Guozijian, the number one official school of the Tang Dynasty), and the School of Mathematical Sciences has resumed normal teaching!

It is worth mentioning that the enrollment scale of the School of Mathematical Sciences this time has been expanded by about two times compared with the previous period. A total of 71 students have been enrolled. In the field of mathematics, it has a tendency to compete with Yanhuang Academy.

In addition to the increase in the number of students enrolled, Kong Yingda also hired three teaching assistants for the Mathematical Institute to help Liu Hongyuan teach the Mathematical Institute. Therefore, the current mathematics library is more than one grade higher than before in terms of the scale of students and teachers!

Inside the math library.

"Eh, have you heard? Yonganhou made a simple needle-throwing game, and he can easily calculate the approximate value of the ancestral rate. It's amazing!"

"I've seen it, but I think it must be a coincidence? After all, the acupuncture thrown out is completely a matter of luck. He can finally get such a result, and it is completely luck!"

"I also think it's a coincidence! If he does it again, the result will definitely be different!"

"I don't think it is necessary! Since Yonganhou 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!"

"Why hasn't Mr. Liu come yet? His old man should have come at this hour!"

"Mr. Liu is here, Mr. Liu is here!"

Just as the students were talking about it, an old man in coarse cloth and white clothes came in at the door, with his gray hair, looking a bit vicissitudes of life inexplicably. The old man was followed by three middle-aged scribes, all deliberately lagging behind the old man by half a step to show respect. The teaching house, which was noisy just now, suddenly became quiet.

"Haha! I just heard that you were all talking about the needle experiment in the newspaper. I think you all want to know if the result in the newspaper is a coincidence, right?"

The old man stood on the podium and looked at the students below with a smile.

This old man is Liu Hongyuan. He was invited back after he had reached the age of retiring his life. After more than ten years in the Guozijian School of Mathematical Sciences, he still feels a little bit dissatisfied here!

None of the students responded, because they have been here for so long, they all know that most teachers at the Imperial College do not like students talking about Li Zexuan. This is a tacit fact.

Although they couldn't make a sound, the students' eyes were all looking at Liu Hongyuan.

Liu Hongyuan has no prejudice against Li Zexuan. On the contrary, he has bought a research book of Li Zexuan’s new mathematics textbook. Seeing the students want to say but dare not say, he laughed again:

"In fact, not only do you want to know, but the old man also wants to know whether the result obtained by Yonganhou is a coincidence. Before the class, the old man prepared a piece of paper with lines on it, and also brought a pack of fine needles, the distance between the lines and the needles. The length is exactly the same as that described in the newspaper. So today we will do a needle injection experiment in the Math Academy to see if the results in the newspaper are a coincidence~!"

While talking, Liu Hongyuan took a gray cloth package from a teaching assistant. Inside it was a piece of lined rice paper and a package of fine needles. The reason why he was late for class today is to prepare for these two things!

When the students heard it, they couldn't help but talk in private.

"Wow! We are going to experiment with needle injection too? Mr. Liu is really enlightened!"

"Hey! If it proves that the results in the newspaper are coincidental, wouldn't our Mathematical Library become famous this time?"

"Haha! In my opinion, it's a coincidence!"

"Hehe, I don't think so!"

Liu Hongyuan patted the table and signaled the students to be quiet, and then he said, "We have 71 students in the school building, and the number is still a bit small. In order to be similar to the total number of needle-throwing experiments in the newspaper, you will follow the order in a moment. Come up and throw the needles. Everyone throws ten times. Be careful not to use too much. Throw the fine needles out of the paper. I and the three gentlemen will help you count the number of times the needles are pressed. Yao Yuanhe, come up, from your side Start~!"

After that, Liu Hongyuan spread out the rice paper and told 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, holding papers and pens, ready to take notes.

The verification experiment of the needle-throwing experiment was officially launched in the National Academy of Sciences.

The entire experiment lasted for more than half an hour before it was declared over. Because it was real-time statistics, the students' thin needles were pressed once, and the teaching assistants immediately counted them. Therefore, not long after the experiment was over, the final results were counted. .

Liu Hongyuan checked his statistics with the three teaching assistants. After finding that the results were all the same, he turned around and said to the students below: “We have 71 students in total, and each of them voted ten times. I voted 710 times. According to the statistics of the three gentlemen and I, there are a total of 226 fine needles on the center line~!"

As soon as his voice fell, a student with a better memory below immediately exclaimed: "Seven hundred ten, two hundred and twenty-six, the result in the newspaper is seven hundred and thirteen, two hundred and twenty-seven! The result is so close to the newspaper~!"

"Wow!"

The students in the whole class were immediately in an uproar ~www.readwn.com~ The three teaching assistants on the podium were also stagnant because at this time, they also recalled the data in the newspaper.

Liu Hongyuan didn't change his face, he turned around, picked up the chalk and started the calculation on the blackboard. Upon seeing this, the students stopped talking and watched Liu Hongyuan's calculation quietly.

710/226=3.14159292…………

When the count reaches seven places after the decimal point, everyone's complexion becomes more exciting, and Liu Hongyuan, who has never been surprised, is no exception. The old man was trembling with excitement at this moment, and he was full of taste when the chalk in his hand fell off, and he heard him mutter to himself:

"A miracle! Old man, the old man actually calculated the ancestor rate to the sixth decimal place...this..."
