Chapter 180 Half Like the Sun, Half Like the Moon

A big class has two sections, each section is 45 minutes.

Li Changqing has finished a lecture, and now it's time for recess.

The students were amazed by what Li Changqing said in class. He described the beauty of mathematics from a very magical field, and his explanation was very convincing and convincing.

Tian Guangwen and Ding Shaoyuan have studied mathematics all their lives, only to discover that mathematics has such a side!
The break time between classes was very short, and the students basically stayed in their seats to digest what Li Changqing said, even after the class was over, the class seemed very quiet.

"Ms. Li, when you talked about Mathematics and Book of Changes, you talked about yin and yang studies. Now there are many fortune-telling magic sticks. May I ask Mr. Li to count what I had for breakfast today?"

Suddenly, a student sitting in the last row wearing a black sweater thought of something very curious, so he asked Li Changqing loudly, which was particularly abrupt in the whole classroom, and instantly attracted the attention of most people.

Ding Shaoyuan was worried that Li Changqing would mistakenly think that the student was scolding him, so he frowned and looked back, then observed Li Changqing's face, and felt relieved when he saw that Li Changqing was as if nothing had happened.

Although the students present were upset that the boy in the black sweater interrupted their thoughts, they were also looking forward to Li Changqing's answer.

Li Changqing's understanding of "Book of Changes" is more from the perspective of Confucianism, from the perspective of governing the country, regulating the family, and cultivating one's morality.

Among the occupations of the Yin-Yang family, Li Changqing knows Fengshui Kanyu, linen clothes, and the five-element array, and he has no inheritance of Yishu in the Book of Changes.

For any other person, Li Changqing would not be able to answer. He would probably pretend to be cold and disdain to answer, but Li Changqing really knew what the student who asked the question had for breakfast. Wasn't this the same as when he drove past the school gate in the morning? , See the classmate who waited in a long line to buy a biscuit and finally dropped it on the ground?

"What's your name?"

Li Changqing remembered that the classmate picked up the sesame seed cakes that fell on the ground and put them in his mouth again. Maybe most people would not do this now, so he was quite interested. Instead of answering his question, he had to ask about it with interest. That student's name.

"Uh, Yuan Tiantian..." Yuan Tiantian was also taken aback, wasn't he asking Li Changqing a question?
"Half like the sun, half like the moon, once fell into the dirt!"

Li Changqing nodded, with a wicked feeling in his heart, he recited a line of poetry in a magnetic voice.

"In the first half of the "Song of Biscuits", Mr. Li is talking about the biscuits you ate, and the second half is saying that your biscuits fell on the dirt!"

"Talent, is Mr. Li right?"

Many students have played a game called Hero Kill, and they are very familiar with Liu Bowen's lines in it. Several students sitting next to Yuan Tiantian immediately confirmed to Yuan Tiantian.

"Could it be that Mr. Li saw me at the time? It's impossible. There are more than 2 students in Wen'an College, and there are thousands of students in the School of Mathematics. I only took one math class. Teacher Li met me at the right time. At that time, my probability was too low, it should be impossible! Could it be calculated?"

Li Changqing had just finished reading, Yuan Tiancai was in a daze, and when he heard his classmate pulling his sleeve, he said in a daze, "It's absolutely correct...".

"Why is Mr. Li's mathematics not only related to Zhouyi, Yin-Yang, and Confucianism, but also magical? Have I studied fake mathematics for decades?"

Since Tian Guangwen didn't sleep well last night, he fell asleep after bumping in the car for a while. He didn't wake up until Li Changqing stopped the car. He didn't see Yuan Tiantian picking up the biscuits. He was surprised that Li Changqing could really figure out Yuan Tiantian's breakfast!
"This is too amazing, I will kneel in class in the future!"

"I was fascinated by the speech of 'Wuwen Xidong' at the opening ceremony, and I felt that my body and mind were sublimated. In the last class, I witnessed the new optimized proof of Fermat's last theorem. This class is directly staged God's algorithm!"

"With Mr. Li here, whoever dares to say that Wen'an College is a third-rate college in the future, I will be anxious with him. Didn't you see that the dean of the Department of Mathematics at Shuimu University is listening straight?"

"Lingling..." After the short break between classes, Li Changqing was about to start teaching again.

Tian Guangwen suddenly recovered from the shock of the first half of the class, remembered his fundamental task of attending the class, and recalled the scene when Li Changqing was lecturing in Lijiaao, worried that he would be fascinated by listening again later, and when the class was over, Li Changqing disappeared and stood up directly.

Li Changqing looked at Tian Guangwen calmly, without speaking or moving.

"Ms. Li, I have a set of data and I don't quite understand the relationship between them, can you help me answer it?"

Tian Guangwen was very worried. If Li Changqing refused him again, he would really have to go back to Yanjing.

"Mmm!", teacher, preaching is also a way to solve doubts. Since Li Changqing is obliged to answer other people's questions in class, Tian Guangwen's questions did not exceed the scope of the class, so he nodded in agreement.

"The data is like this, Mr. Li, look..."

Tian Guangwen was overjoyed, went to the blackboard, and used a relatively advanced algorithm to encrypt and write the data given by the Institute of Physics on the blackboard. If he was not proficient in number theory, he would not understand what he wrote. There are four blackboards in total. Tian Guangwen The writing speed is extremely fast, and it is quickly filled with various numbers and symbols.

"Mr. Li, do you understand?"

Tian Guangwen turned his head and asked Li Changqing, feeling very nervous. If Li Changqing failed to understand what he wrote, even if Li Changqing agreed to help him, it would be impossible to find out the internal connection between the data, so all his efforts would be useless. It's just a joke.

"Understood!", Li Changqing understood the encrypted data written by Tian Guangwen on the blackboard at a glance, and felt vaguely familiar.

"Great! What's more, you can continue to read. If you understand, just nod, and I will continue to write!"

Tian Guangwen was excited. Li Changqing was able to understand the data he encrypted with the number theory algorithm in such a short period of time, which shows that Li Changqing has a solid foundation in the field of number theory. Then it is very likely that Li Changqing can help him find the internal connection between the data. Added!
"Okay!" Li Changqing felt a little interesting.

Tian Guangwen cleaned the four blackboards and continued to write on the blackboards. After finishing writing, he asked Li Changqing with his eyes, and Li Changqing nodded.

"Crack creak..."

In the whole classroom, there is only the sound of Tian Guangwen’s chalk rubbing against the blackboard. The content on the blackboard is like a bible to the students present. They can’t understand it at all, but there is a magical power that attracts them. An Jing Quietly watching and admiring.
