The girl nodded and was about to leave when Jiang Fan asked again: "Classmate, how long will this lecture last?"

"Two or three hours."

The girl answered.

Jiang Fan smiled and said: "Then do you know which classroom it is in?"

The girl said: "I know, do you want to go? I can take you there. It just so happens that I also want to go to that teaching building."

"Thank you then."

The two of them immediately followed the girl and walked towards the teaching building.

"Xiaofan, what are we going to do here? Just wait here for my little sister."

Jiang Long asked.

Jiang Fan smiled and said: "I have nothing to do anyway, so I just went over and took a look."

"We can also take the opportunity to see if my little sister is studying seriously, haha."

In fact, Jiang Fan also had other things on his mind.

After taking his vacation, he will go to his alma mater to hand over his position as a visiting professor.

Then, you may go to an Air Force Academy to see if you have a chance to get in touch with fighter aircraft, so as to prepare for the next improvement and optimization of third-generation fighters.

After walking for ten minutes, we finally arrived at the teaching building.

The girl pointed to the stairs and said: "You go up from here, to the fifth floor. There are two large classroom halls above, 501 on the far left."

"Okay! Thank you, classmate!"

After separating from the girl, the two walked up to the fifth floor.

Before reaching the fifth floor, I heard the teacher's lecture coming from the classroom on the fifth floor.

Jiang Fan and the others went up the stairs on the right.

You have to go through the classroom hall of 502 to get to 501.

The two looked at the house number and continued walking forward.

But at this time, Jiang Fan stopped and looked at the classroom podium in 502 in surprise.

Li Hengzhi!

I go!

Why is he here?

That's right, at this time, the person on the podium teaching more than 200 students below was none other than Li Hengzhi, the mathematics teacher at the Army Command College who had taught Jiang Fan before!

"Xiaofan, what's wrong?"

Jiang Long asked.

"It's okay. Let's go."

Jiang Fan glanced at Li Heng and continued walking forward.

Arriving at Classroom 501, the two quickly spotted Jiang Xiaoxuan's figure through the window.

At this time, she was sitting in the second to last row at the back, listening to the class attentively.

Because there are not many students studying dynamics, and many classes have classes in the afternoon.

Therefore, the 501 Teacher Hall was not as full of people as the one in 502.

The back row and half of the second-to-last row are empty.

University classrooms are not very strictly managed.

For public lectures like this, as long as it does not interfere with the teacher's lecture and students' listening, they are allowed to enter through the back door and sit behind and follow the class.

"Let's wait outside. My little sister is in class, so it's best not to disturb her."

Outside, Jiang Long said to Jiang Fan.

"It's okay, let's go in and listen."

Jiang Fan smiled and said: "Just in time, I also want to learn dynamics."

Jiang Long smiled and said, "Then you go in. I'll wait outside and smoke while I'm at it. Anyway, I can't understand what's inside."

"OK."

Jiang Fan nodded, then walked in from the back quietly.

Then, he sat behind Jiang Xiaoxuan.

Because Jiang Xiaoxuan was too serious, she didn't notice anyone coming in from behind.

On the podium, the professor giving the lecture looked to be in his fifties, wearing a pair of glasses, and was gentle and elegant.

At this time, we are talking about the essence of some dynamics.

Schools like the aerospace industry have relatively high requirements for knowledge in physics, mathematics and even chemistry.

Otherwise, it will be difficult to learn the principles.

At present, the country also needs a large number of talents in this field.

Therefore, the school will often have academic exchanges with top aerospace universities and invite experts with more teaching or practical experience to give lectures.

The teacher on the podium, the girl said, was from the Air Force School.

The Air Force School is the top air force school for national defense that trains various aerospace talents and pilots.

The teachers and experts there are extremely knowledgeable in aerospace expertise.

Jiang Fan could feel it after just listening for a while.

That professor is extraordinary!

Even in the Air Force School, he is definitely a more authoritative professor!

However, although Jiang Fan has never studied dynamics or anything like that.

But don't forget, his current IQ is as high as 167, and he is among the top in the world in mathematics.

Dynamics and mathematics are closely related.

Moreover, he now has knowledge about aerial flight equipment, and he also has very majestic knowledge about dynamics.

While at the frogman camp, Jiang Fan devoted himself to research for several months.

Therefore, Jiang Fan could understand what the professor mentioned above as soon as he heard it, and he could also draw inferences from one instance to another.

Even for the topics he talked about, as soon as Jiang Fan read out the topic, he could already figure it out in a flash of his mind.

Jiang Fan also looked at Jiang Xiaoxuan's notes earlier and found that Jiang Xiaoxuan's understanding of dynamics was also very good.

"It seems that this little girl has quite a lot of talent."

Jiang Fan nodded slightly, "Let's see if we can find some time to give her a good shake."

After listening for more than an hour, the professor on the podium also stopped.

"Okay, there are still thirty minutes left."

"I'll give you a question, copy it down, go back and do the math, and you can check the information however you want."

"Of course, if someone can figure it out in the remaining half hour, that would be the best!"

"If he can do it, I can accept him as my disciple, haha~"

As soon as these words came out, the more than two hundred students present suddenly became excited.

Professor Wang An is a famous professor in the field of dynamics!

His reputation is not only famous in the Air Force Academy.

Even other science, engineering and aerospace schools with dynamics majors are also extremely famous!

If you can become his disciple, you will definitely learn a lot of knowledge. It is not an exaggeration to say that you have stepped into the field of high-end scientific research!

Soon, Wang An finished writing a question about dynamics on it.

The students quickly copied it down, and then immediately began to calculate with full concentration.

Everyone wants to solve this problem within half an hour and become Wang An's disciple.

Including Jiang Xiaoxuan.

Jiang Fan, on the other hand, did not take action.

He frowned slightly and used his brain to calculate the question, and soon, he figured it out.

………………

Four thousand words.

There will be more later.
Chapter completed!
