Standing on the podium that had been prepared in the auditorium, Ji Zhen waved his hand.

Subsequently, the recording of the public class officially began.

"There are a lot of people here today! What makes me happy is that half of them are girls. I hope you're here because you love math. And not because of my looks. ”

At the beginning, Ji Zhen told a joke, which caused the students present to laugh lightly.

"Among the students present, I also saw a lot of old faces. My former undergraduate students and elective students. I have no doubt about my own teaching ability, so the arrival of you old faces seems to mean that you are not studying hard enough! ”

After making a joke with the classmates who were doing it, Ji Zhenshi entered the rhythm of the open class.

The old face did exist, Ji Zhen swept it over at a glance, and saw Bei Weiwei and his roommates in the bedroom, Erxi, Sisi and Xiaoling. Then I saw Xiao Nai sitting next to Bei Weiwei and his three roommates.

The recording of the public class is not a one-time recording, but is divided into several class hours, interspersed with breaks.

Ji Zhen has participated in a lot of lectures and speeches, so in the face of public classes with general teaching tasks, there is nothing to be afraid of.

Although the knowledge system is different from anti-gravity materials, Ji Zhen's teaching method is no different.

In the same way, they all focus on divergence and guidance, and introduce the mechanism of independent thinking to explain the course in the form of points and areas.

Ji Zhen believes that the knowledge he explains is not complicated, and it is not difficult for every university mathematics teacher.

Therefore, what he wants to pass on to the audience is not these mathematical knowledge, but the mathematical thinking that is elicited by knowledge.

Everyone thinks differently, and the same is true for mathematics. What he showed his classmates was his way of thinking.

Time to rest.

Ji Zhen and his two teaching assistants discussed what was said, while the students who listened to the lecture below were discussing.

"Wow, it's really Professor Ji, his mathematical thinking is too sensitive, and he turns too fast."

"What is this, it's all basic. Professor Ji's way of thinking is what is surprising. His perspective on mathematical problems is very bizarre, different from the way of thinking of ordinary people, and he can always cut to the core at once. ”

"Professor Ji's knowledge is so profound, it is just a point product, which can lead to deeper mathematical problems."

The students who said these things basically have some research on mathematics, and they can keep up with Ji Zhen's thinking level, and they have gained a lot from this lecture.

There are others who don't understand it.

The reason why they don't understand it is because they can understand the obvious, but once they go from shallow to deep, they are at a loss.

This requires divergent thinking and a talent for being very sensitive to mathematical needs. Be able to draw inferences from one another, and even multi-faceted understanding and application.

After a ten-minute break, Ji Zhen spoke again.

···

"How's today's open class?"

In the evening, Ji Zhen returned home from school, and as soon as he entered the door, he was asked this question by Xu Linfei.

"Look at Weibo, there should be a discussion on Weibo."

Xu Linfei was stunned for a moment, and then said in surprise, "It's on Weibo so soon?" ”

Replacing his shoes with slippers, Ji Zhen walked into the house, poured himself a glass of water, and drank it in one gulp.

"Isn't it, now the videos are on the Internet. The video recorded in the morning, and then NetEase expedited the subtitles, and there was no need to do post-production, so now it is available on the Internet. ”

Xu Linfei shook her head, "I don't think about the evaluation on the Internet, what do you think in your heart?" ”

Ji Zhen thought for a moment, as if recalling the situation of today's open class, "I think it should be good." ”

After the course was explained, many people asked the teaching assistants for questions. Ji Zhen likes this kind of learning atmosphere very much.

"Well, to celebrate the opening victory, let's go to a big dinner."

Ji Zhen raised his head and asked hesitantly, "You didn't cook?" ”

Generally speaking, if Xu Linfei is at home, Ji Zhen goes home to eat at night.

Apparently, she is at home today.

There is only one truth, no cooking.

Xu Linfei hugged Ji Zhen's arm and shook it, "I originally planned to cook after playing a game." ”

"But after the game was played, the company had another incident, so I didn't cook."

"Okay, go out and eat."

Ji Zhen just changed his slippers, but now he turned around and went back and changed into casual shoes.

Ji Zhen doesn't care about food, so he doesn't have much research on restaurants.

However, Xu Linfei is very familiar with some restaurants, and she can say exactly what dishes are delicious.

chose a very secluded restaurant, and Ji Zhen and Xu Linfei ate the food presented.

"The variety show has been scheduled, and I'm going to record the show "Run" tomorrow."

In the middle of the meal, Xu Linfei said to Ji Zhen.

Ji Zhen nodded, "It's okay, I have more work in the future, and the time may be a little tight." If you wait for me to eat together every day, it will not be good for your stomach. ”

"After I came back from the recording of the show, the online drama on the company's side is probably ready. By then, I'll be busy, and I won't be able to cook for you every day. If it's too late, you'll eat in the school cafeteria. ”

When the two were eating, they talked about the bits and pieces of life, vegetables, rice, oil and salt.

It's not vigorous, but it's ordinary.

···

Time passes.

In the blink of an eye, three months have passed.

Ji Zhen runs back and forth between the two buildings, the Institute of Materials and Yenching University.

The former is to explain anti-gravity materials, while the latter is to explain the knowledge of mathematics open courses.

Through these two explanations, Ji Zhen deeply felt that his energy and energy were limited.

There is still a big gap between the underlying basic science and foreign developed countries.

Just relying on his words, it is a bit too much to lead Huaxia to rush out of the earth and enter space.

Ji Zhen is not the kind of person who resists any pressure on himself, he needs someone to share his pressure, and he needs more people to participate in the road to the rejuvenation of the great motherland.

"Xiao Jiu, can I make a system?"

Inspired by online literature, Ji Zhen still has some understanding of routines.

So, he thought about getting a few gold fingers out.

Xiao Jiu, who had been silent for a long time, answered Ji Zhen's question, "Using the Realm Source Power, you can make the system you refer to in your memory." ”

"However, the world has great limitations. You, a cultivator, are already the virus of the world, so the system you have refined cannot take the path of single-person transcendence, but can only take the path of science and technology. ”

Ji Zhen nodded, "I'm not ready to take the transcendent path." ”

"Also, the refining system involves the law of creation, which cannot be achieved overnight, it can only be a little bit from simple to difficult."
