Chapter 169

Gu Lu asked Bi Qi to leave first, and then left Ma Zhengxuan behind.

"Bring a chair and sit down. ”

Gu Lu asked Ma Zhengxuan to move a chair and sit down, then crossed his fingers and looked at Ma Zhengxuan with concern, "Are you still adapting to this time in college?"

Ma Zhengxuan put his hands flat on his knees and nodded and replied, "At the beginning, I felt that college life was very different from high school life, but now I have adapted to it. ”

"What are you busy with now, I mean, except for studying?" Gu Lu's smiling gaze fell on Ma Zhengxuan.

From Bi Qi's words some time ago, Gu Lu knew that Ma Zhengxuan had been a frequent visitor to the library since he entered the university.

Entering the university, although there is no teacher's constraint, Ma Zhengxuan still follows the rhythm of high school and spends most of his time reading and studying every day.

And, even harder than high school.

In terms of learning, Gu Lu didn't have to worry about Ma Zhengxuan at all.

As for other aspects, Gu Lu, as Ma Zhengxuan's high school teacher, naturally has to take special care.

"I've been working as a tutor lately. Ma Zhengxuan lowered his head and replied.

"Tutor?" Gu Lu sighed.

"Well, a senior sister in the work-study club I joined introduced to me, mainly tutoring a senior high school girl in mathematics and physics. Ma Zhengxuan replied truthfully.

Gu Lu understood in an instant.

It is still relatively common for Yan students to be tutors.

Especially the freshmen of Yenching University, who have just entered the school, are the sweethearts of the tutoring market, and countless parents of high school seniors are competing for them.

After all, every student who can be admitted to Yan University will definitely have top-notch grades in high school.

The freshmen, because they have just experienced the college entrance examination, have a deeper understanding of the knowledge of the third year of high school than most high school teachers.

The price of having a student tutor is lower and more effective than that of a professional teacher.

Gu Lu knew Ma Zhengxuan's family situation.

At that time, Ma Zhengxuan helped Haicheng City to obtain the title of the top student in the college entrance examination, and the Haicheng Education Bureau and Haicheng No. 1 Middle School gave Ma Zhengxuan a total cash reward of 150,000 yuan.

150,000 yuan.

Even in a high-consumption city like Yanjing, 150,000 yuan is enough for Ma Zhengxuan to survive four years of college.

However, it is obvious that Ma Zhengxuan did not use the 150,000 yuan and was ready to use it all for himself.

Gu Lu opened his mouth, wanting to say something, but in the end he could only sigh lightly.

"What's the price of your tutor?" Gu Lu rubbed his eyebrows and asked.

"One hundred and five in an hour. I teach for a total of three hours a week. Four hundred and fifty yuan, enough for me to spend for a week, and I can still have some money to send home. Ma Zhengxuan showed a rare happy smile.

This price is considered a normal price.

Compared to some college students, it is much better to work part-time as coolies.

But this speed of making money is still a bit slow.

Gu Lu has a lot of places to make money, but the current Ma Zhengxuan's mathematical level has not yet been reached.

Gu Lu forced it over, not saying whether the other side would agree, Ma Zhengxuan's side might not be willing.

So, just wait.

It is estimated that in another half a year, Ma Zhengxuan will be able to grow up.

Gu Lu and Ma Zhengxuan continued to chat.

One of them, time and time again, is health!

Staying up late is a bad habit!

Although Gu Lu, a teacher, also stayed up late, it did not affect his serious face and warned Ma Zhengxuan to let him stay up less late in the future!

Staying up late will not only affect your health, but also cause kidney deficiency and chicken weakness.

It can also cause hair loss and reduce the chance of losing orders.

In addition, Gu Lu also asked Ma Zhengxuan to pay attention to his diet.

Don't just eat vegetarian to save money, eat more meat to replenish your body.

Ma Zhengxuan is like this now, Gu Lu feels that he is a little thinner than when he was in high school.

As for meat, Gu Lu recommended Ma Zhengxuan's "called a chicken" in the farm restaurant.

Call a chicken from time to time to enjoy it, Gu Lu has been used to such days during this time.

…………

Fast forward to the beginning of December.

It was another Monday, Gu Lu finished the morning class, returned to the office after lunch, and just sat down, he received a message from Su Xi.

Su Xi: "Teacher Gu, there was a lecture by Shinichi Wangjing recently, and I have already got the invitation, will you go?"

A photo is attached below.

In the photo are two invitations, with red covers, and the contents are all in Japanese.

Gu Lu has studied Japanese for a while, so he can recognize what is written on the invitation.

Time: 17:00, December 8, 2017

Venue: University of Tokyo City Hall

Speaker: Shinichi Wangi

Lecture Title: "Elaboration of the Intercosmic Teichmüller Theory Based on the ABC Conjecture"

Many thoughts flashed through Gu Lu's mind in an instant.

Shinichi Mowai is a professor at the University of Tokyo in the island country and one of the representatives of the mathematics community in the island country.

His most important achievement was his 512-page paper proving the ABC conjecture.

Even though, because Shinichi Moboi's 512-page paper is so obscure, no international mathematical organization has publicly declared Shinichi Mojii's proof process correct.

But it is not denied that in the field of ABC conjecture, Shinichi Mowai is indeed the first person.

It is just like the position that Chen Jingrun achieved in the field of Goldbach's conjecture.

However, for Gu Lu himself, this lecture did not attract him much.

During this time, because of Su Xi, Gu Lu went to the academic lectures of many bigwigs.

But most of them are domestic, such as Academician Zhang's report on the assumption of the unity theory of differential geometry, Academician He's latest progress on the Kakutani conjecture, and so on.

The only time I went abroad was to Malaysia to listen to a report on the latest achievements of a famous Asian mathematician, and I flew back the same night after listening to the report.

After a few lectures, Gu Lu gained a lot.

Since Su Xi didn't know any specific branches of mathematics, he always chose the speaker with the highest title when selecting lectures, and at the same time took into account the time factor.

There are no restrictions on the specific branch of mathematics to which the content of the report belongs.

Therefore, Gu Lu has listened to lectures in various branches of mathematics, not limited to the direction of number theory and geometry.

For example, algebra, topology, function theory, functional analysis, ......

Professor Shinichi Wangi's ABC conjecture can be regarded as a problem in the direction of number theory, which corresponds to Gu Lu's main direction of attack.

But after thinking about it for a few seconds, Gu Lu decided not to go to this lecture.

One is that the location is too far away, and in that place in the island country, it will waste a lot of time to go back and forth.

The second is the content of the lecture, which is the intercosmic Teichmüller theory, that is, Shinichi Moboi's 512-page paper.

To be honest, Gu Lu has not read that long paper, so naturally he has no understanding of the intercosmic Teichmüller theory that is mainly expounded in his paper.

If he listened to it in the past, it is estimated that he would be like Su Xi, and he would fall asleep after hearing half of it.
