Chapter 629 The Happiness of Teaching a Class

Friday, the last day of the week.

Whether it is an office worker or a student.

After spending today, we have two wonderful weekends.

Therefore, on Friday, everyone is often in a very happy and relaxed mood.

But this Friday, for the students of the Department of Mathematics and Department of Physics of Yanda University, it seemed so different.

As early as in the last number theory class and quantum mechanics class, Chen Zhou's substitute teacher told these students that there would be a surprise in the next class.

However, out of the idea of ​​creating a sense of expectation, the two substitute teachers did not tell these students what the surprise was.

Because of this, these students, on this day that should have been relaxed and happy, waited quietly for the weekend.

I have some expectations that don't belong to this day.

For this reason, the students of the Department of Mathematics, before the number theory class started in the morning.

One by one, they came to the lecture theater early.

The purpose is to see what kind of surprise this substitute teacher will bring them in the first place.

In the lecture hall, the students were also discussing with each other, what would this substitute teacher bring over later.

As a result, the entire classroom was a little chaotic.

Until the door of the lecture theater, a young man appeared.

At first, these students didn't pay attention.

But when this young man walked into the classroom with an elementary number theory textbook.

It was only then that they realized why this person looked so familiar.

For a moment, these students did not react.

Because, they never thought that Professor Chen Zhou, who never came to class, would appear in the classroom.

But it was only for a moment.

After that moment, with a burst of cheers, the classroom immediately fell silent.

There is a look of excitement in the eyes of every student.

They just want to tell the substitute teacher that this surprise is simply too big!

Notice that the noise value is obviously different before and after I walk into the classroom.

Chen Zhou couldn't help smiling slightly.

Yes, it is quite possible to maintain discipline.

After walking to the podium and standing up, Chen Zhou put the textbooks on the podium, then raised his head and looked at the students under the podium.

These students also stared at Chen Zhou in unison.

Chen Zhou cleared his voice and said, "Hello, students, today's class will be taught by me personally, you..."

Before Chen Zhou could finish speaking, the students in the audience said in unison: "Hi, Professor Chen! We must pay attention to the class!"

They welcome their professors with the fullest enthusiasm.

Hearing this voice, Chen Zhou smiled again.

He felt that there should be no need to say what he said later.

In order to live up to the enthusiasm of these students, it is better to start the lecture as soon as possible.

"Okay, you all listen to the class carefully, and I will give a good lecture..."

As Chen Zhou spoke, he began to flip through the textbook until he reached the page he had folded.

This is also the current progress of the students in the Department of Mathematics in the course of elementary number theory.

"Please turn to page 65 of the textbook, which is the page of the basic knowledge of Tongyu. We have started the class..."

As Chen Zhou's voice fell, all the students flipped through the textbooks together.

Turn to what Chen Zhou said, page 65.

During this process, everyone moved extremely quickly, for fear of delaying for a second.

And no one is willing to spend this class in a daze.

After all, this is Professor Chen Zhou's class!
This is their idol, a role model for all Yanda students!

They have been looking forward to Chen Zhou, who is the professor of the class, to come and teach them a class.

And now, when that expectation comes true, how can they live up to that expectation?

"The basic knowledge of congruence in Chapter 3 can be combined with the congruence equation in Chapter 4..."

After glancing at the marks he had made on the textbook, Chen Zhou also started his formal lecture.

The formal lecture will naturally not be the same as his previous trial class.

The previous trial class was to show himself.

The current formal lectures are to impart knowledge to students more accurately.

However, 10 minutes after the formal lecture.

The speed of Chen Zhou's lectures began to gradually increase.

It wasn't Chen Zhou's intention, or something else.

It's because, when he was flipping through the textbook last night and preparing for the lesson, Chen Zhou discovered that the content inside was too simple.

Really, there is nothing to talk about.

This also made him unknowingly speed up the lecture during the lecture.

"The basic properties of the congruence class and the residual system, as well as the integrity and structure of the residual system, are all very simple, so I won't go into details, just look at it for yourself..."

"I can tell you about the properties of this Euler function (m)..."

"In number theory, for a positive integer n, Euler's function is the number of numbers that are relatively prime to n among positive integers smaller than n...Euler's function is also called φ function, Euler's quotient..."

"To end the content of the Euler function, the following is the public key cryptosystem. If you want to know about this, you can just study it. When you really want to engage in research in this area, you can go deeper..."

"As for the congruence equation, the content is similar to the basic properties of the congruence class and the remainder system, and the depth is also average. Just look at it yourself..."

"The following are the exponents and primitive roots of Chapter 5..."

In more than half an hour, Chen Zhou completed the teaching of the two chapters in the textbook without knowing it.

And he finally realized what the joy of being a teacher is.

In the past, he didn't quite understand why these professors always taught classes like flipping through books.

Now he understands.

In addition to the fact that the content is really simple, this kind of teaching method is also quite interesting.

Of course, Chen Zhou is also based on the way of teaching after a certain choice.

He didn't flip through the whole book in one brain, but only left an impression on these students that they were all self-study.

Chen Zhou gave full play to the role of detail and appropriateness.

He didn't miss any of the content that should be expanded, and unfolded it all, explaining it in detail.

He will never take a second look at the content that should be mentioned in one sentence.

Otherwise, it is a disrespect for time and a disrespect for students.

"Well, Chapter 6 is about the content of the indeterminate equation, about the content of the indeterminate equation..."

After another quarter of an hour or so, Chen Zhou successfully crossed Chapter 5 and started to enter the content of Chapter 6.

For Chen Zhou's lecture speed, most of the students in the audience can still keep up.

After all, if you want to gain a foothold in the mathematics department of the first department of Yanda Madhouse, you need your own strength and preparation before class.

They even felt that Chen Zhou's lecture was well grasped.

Let them listen to the lectures comfortably...
