Chapter 149

Chapter 1 of the advanced mathematics talks about the concepts of functions and limits.

This includes several small pieces of content such as the relationship between mapping and function, the limits of sequences and functions, the algorithms of limits, etc.

Gu Lu has no habit of doing PPT.

In his opinion, things displayed on PPT are often not written on the blackboard, which makes the students more memorable.

"The research object of advanced mathematics is the variable quantity, so the so-called functional relationship is the dependence between variables, and the limit method is the basic method of studying variables. In the first chapter, it mainly talks about basic concepts such as mapping, functions, limits and functions, as well as some of their properties."

"Let's talk about mapping first. Regarding the concept of mapping, there are also what single and double-shooting are. I will talk about it more. Your high school teachers should have talked about it. Also, inverse mapping and composite mapping, I think your high school teachers must have taught you, so I won't repeat it. Come, let's look at the content of the next section..."

All students: "???"

The high school teacher...has said it?!

But they clearly remembered that the high school teacher said that the university teacher would definitely teach after arriving at university, so they didn't say anything about it.

There is a kind of trust called university teachers and high school teachers.

High school teacher: "You college teachers will definitely teach this!"

University teacher: "You high school teachers must have talked about this, so I won't repeat it!"

Students: “MMP!”

…………

Giving lectures with a group of Yan University students, Gu Lu clearly felt the difference between the two compared to teaching with a group of high school students before.

The most obvious point is that the efficiency of the two in absorbing knowledge.

The gap is not a little bit.

At Yan University, any class is full of academic masters.

Anyone is the top student in their respective schools in high school.

In terms of listening efficiency, the overall performance is much better than the situation in high school classes where listening efficiency is uneven.

For some content, Gu Lu doesn’t have to repeat it two or three times like teaching high school students.

Everything is passed over once.

The students listen efficiently, and Gu Lu speaks efficiently.

After two classes, Gu Lu finished the content of the first two chapters of the senior high school mathematics.

…………

There are two numbers and two advanced mathematics classes a week, and a total of four major classes.

This is Gu Lu’s current course arrangement.

Compared to high school, this is naturally much easier.

But for university teachers, the course arrangement is quite compact.

For some associate professors, it is usually only one or two classes a week.

But Gu Lu is still a hard-working little lecturer now. The group of professors spend most of their time focusing on research, and the professors are too lazy to teach basic courses like numerals and advanced mathematics, so they can only come to them.

However, Yan University’s lecturers are not ordinary people.

In other universities, students who graduate from master's degree from prestigious universities are fully qualified to be lecturers when they enter the school.

But it is very different in Yan.

The minimum education of a lecturer at Yan University is to graduate from a doctorate.

Moreover, at least, doctoral students from the top ten universities in China must be recruited by Yenching University.

The rest are generally not considered unless otherwise specified.

In fact, there are currently many lecturers at Yan University. In terms of qualifications and abilities, they are enough to be awarded the title of associate professor in other universities.

However, due to the extremely difficult promotion mechanism within Yanda University, he can only be willing to be a young lecturer.

However, it is rare for Yan University teachers to switch jobs to other schools.

Yan University’s teachers, whether in terms of resources or status and connections, seem to be comparable to Tsinghua University next door in China.

Especially Yan University Mathematics College.

The Department of Mathematics of Yan University has always been firmly ranked first in China, and naturally gathered countless top bull markets in the industry.

Some mathematicians who focus on scientific research almost squeezed their heads and wanted to enter Yanda University Mathematical Academy and get in touch with this group of top big guys.

But Yan University Mathematics Institute will only accept merits.

And in a few years, a few of these lecturers who were admitted to the school will definitely become the group of big-name figures they once admired.

If the cycle continues, the mathematics department of Yan University will only become stronger and stronger if this virtuous cycle continues.

But this is only for the country.

Internationally, there are many universities with mathematics ranking above Yenching University.

On the latest list of mathematics majors in QS world universities, Yan University’s mathematics department is only ranked 20th.

To enter the top ten, it will take generations of people to work hard one after another.

Ten years of trees, hundred years of trees.

Yan University’s century-old heritage is no worse than any university in the world.

With the continuous rise of young talents, it is only a matter of time before Chinese mathematics catches up with the pace of the world.

…………

Lunch was solved by Gu Lu in the farm restaurant.

In fact, several restaurants in Yanda University, the braised chicken rice from Wu Canteen is most in line with Gu Lu's appetite.

But one is that it is too far away, and the other is that it is the peak lunch period, and the window for braised chicken and rice is a predictable thing.

Gu Lu chose a farm restaurant very close to the Mathematical Academy building.

"Auntie, let's have this, braised pork and potatoes." Gu Lu pointed to the full pot of braised pork and said to the canteen aunt wearing masks and gloves.

"Okay! Young man, wait!"

The aunt of the cafeteria waved a large iron spoon and put a spoonful of potatoes into Gu Lu's stainless steel plate!

Gu Lu: "..."

Gu Lu lowered his head and took a closer look.

It was indeed a plate of potatoes. Gu Lu flipped over with chopsticks, but he didn't even see half a piece of braised pork.

There were only a few minced meat crumbs floating on the soup.

this……

Sure enough, after going to college, even the aunties in the cafeteria became lazy.

In high school, the canteen aunt would symbolically shake the spoon and shake the pieces of meat in the spoon.

But when they arrived at university, they were too lazy to be perfunctory.

Use the unique skill of "meatless spoon" directly, allowing you to experience the fear of being dominated by the aunties in the high school canteen on the spot in minutes.

Gu Lu once again affirmed his previous thoughts.

His lifelong enemy has appeared, that is... the canteen aunt!

He had a smooth journey before, and he suffered many losses under the canteen aunt.

After returning from abroad, Gu Lu obviously felt that he had lost a lot of weight.

Now we have finally found the root cause.

It would be strange if you were poisoned by the canteen aunt for a year.

Gu Lu felt that he needed to make up for it.

So Gu Lu went to the window next door called "Called a Chicken" and called a Chicken.

The chicken is very small, probably still a chick.

Gu Lu first kneaded its body with his fingers and stroked every inch of the chicken's skin.

Then put on the condom, cough... no, put on the gloves, hold the chicken and enjoy it.

"Ah, it's comfortable!"
