I failed a course, and the system became my study supervisor.

Chapter 78 Alarmed China’s Military Industry?
After the internship and the National Day holiday, Xu Ling's study and life entered a stable period.

Due to the tight schedule during the internship, Xu Ling has not been able to fulfill his duties as a teaching assistant.

Zhang Zhongyao assigned all the Q&A sessions for the entire month of September to another teaching assistant.

Now, Xu Ling had no more excuses. He would be the one to complete the review of Chapter 3 of Mechanics.

Chapter 3 discusses non-inertial systems, which is a major difficulty in the entire mechanics course.

……

"Classmates, let me first review the concepts of absolute micro-business and relative micro-business.

The derivative of time in the static reference frame K is called the absolute derivative and is expressed as D/Dt..."

"Let us consider what happens when a time-varying vector B is acted upon by D/Dt in a moving reference frame K."

As he spoke, Xu Ling picked up the chalk and wrote down several transformation formulas on the blackboard.

DB/Dt=D(Bxi+Byj+Bzk)
……

=dB/dt+ω×B
"If we can get this equation for any vector, then we can naturally substitute B=r or B=v into the equation, and we can naturally deduce the transformation relationship between the acceleration and velocity between the moving and stationary systems."

Xu Ling stopped talking here. He thought there was no need to continue what he was going to say.

But the reaction from the audience seemed a little off. Several students in the front row were still staring at Xu Ling eagerly.

Xu Ling was a little confused and asked, "What's wrong? Why are you looking at me?"

"Assistant, aren't you going to push it down?"

A girl asked in a low voice.

"No need for that? Isn't the next step very simple? Just apply the relationship between absolute and relative micro-businesses, right?"

Xu Ling replied with some confusion.

But many classmates still looked at him.

Xu Ling reluctantly finished explaining the entire derivation, including the inertial centrifugal force and the Coriolis force.

Xu Ling was very upset about this. He had wasted a lot of time. How was he going to talk about the limitations of Newton's concept of absolute space and time later?
So, in order to finish covering all the content, Xu Ling began to speed up and not talk about anything that was a little simpler.

Xu Ling himself may not have realized that when he gave lectures, he gradually became like Zhang Yongjie.

The students in the audience were complaining just like when Xu Ling taught Zhang Yongjie's class.

"This teaching assistant speaks so fast, and the material he explains is so difficult."

This was what Xu Ling overheard when he walked out of the classroom.

In response, Xu Ling expressed his innocence.

Shouldn’t we master the simple things during class?

……

Back in the dormitory, game design is in full swing.

At this time, Yang Chaojie and Wang Rui were both gathered in front of Qin Kai's table.

Xu Ling also came over.

I saw Qin Kai making an animation of "GPA Devourer".

"Holy crap! That's amazing! He can even do detailed work like animation!"

Xu Ling couldn't help but admire.

"It's not that great. For this pixel art style, I just need to draw a few textures and change them every frame."

Qin Kai said modestly.

But Xu Ling was still somewhat amazed and confused. Why did he choose physics as his major when he was so proficient in computers?

"By the way, Xu Ling, now that the game mechanics are designed, you can try writing the code."

At this time, Yang Chaojie turned and said to Xu Ling.

Xu Ling nodded.

This was something Xu Ling and Yang Chaojie had agreed upon in advance. Xu Ling would not participate in the design of the game, but would only write code and treat the game as a programming problem to strengthen his programming skills.

The game mechanism designed by Yang Chaojie is very simple, similar to the MapleStory that was popular when Xu Ling was a child. He probably wanted to play on the nostalgia card.

Xu Ling's job was simple: he only needed to write about the increase or decrease of the character's health, mana, gold, and other values. He also had to write about the judgment of the death of characters and monsters.

Yang Chaojie had already written the rest of the code, including character movement and monster tracking. Overall, the work was progressing quickly, and Xu Ling estimated it would be ready for submission in a few days.

……

A week passed quickly and Yang Chaojie had submitted his work, but the final evaluation would not take place until the end of the semester.

Xu Ling stopped paying attention to this and devoted himself to his daily routine.

In addition to attending classes, Xu Ling also follows up on the ABS system he previously researched, constantly consulting materials and trying to find new directions for further optimization.

At the same time, when he has free time, Xu Ling will go to Zhang Zhongyao's laboratory to help, and stare at the particle accelerator's console with several senior brothers and sisters.

Life is very dull.

Until this day, Xu Ling received an email from JPS informing him that the paper on the ABS system had been officially published.

At the same time, the relevant patent application was formally approved.

According to relevant patent regulations, Xu Ling's ABS system is an invention patent with a patent protection period of 20 years.

Xu Ling had anticipated the patent and paper, and with the experience of the last PRL, although Xu Ling was excited, he was not exaggerated.

But what surprised Xu Ling was that Zeng Boyuan, whom he had not contacted for a long time, called him.

"Xu Ling, do you have time? Come to my office."

Zeng Boyuan's somewhat old voice came from the other end of the phone.

"Ah? Now?"

"Yes, as quickly as possible."

"Is there a problem?"

Xu Ling was a little confused and asked quickly.

"Good! Come on over. You still remember where my office is."

……

Walking on the road, Xu Ling kept guessing.

Are you going to let me compete again?
But I haven’t heard of any authoritative competition in the second half of the year?
About the paper?

But I didn't even publish it in the college newspaper? Is it really necessary to make such a big fuss?
With all kinds of questions in mind, Xu Ling came to Zeng Boyuan's office.

The office door was open, and besides Zeng Boyuan, there was also a little old man inside.

Out of politeness, Xu Ling knocked on the door frame.

"Hey? Classmate Xu Ling is here, come in quickly."

Zeng Boyuan greeted warmly.

Then he introduced: "This is Vice Dean Zhou from the School of Physics."

Dean?

Xu Ling suddenly became a little nervous and said quickly, "Hello, Dean Zhou, hello, Dean Zhou."

"Haha, don't be nervous. Heroes really emerge from youth!"

Zhou Chengkang praised.

Ok?
Is it because of the JPS paper?

Xu Ling was flattered but also a little confused. He had never seen the dean personally come to praise him when he published PRL before.

Seeing Xu Ling's puzzled look, Zhou Chengkang finally explained:

"I asked you to come here this time through Professor Zeng because of the article you recently published on battery systems.

Just in the past two days, comrades from China's military industry contacted me and wanted to contact you to discuss the patent issues of this technology.

I'm giving you a heads-up in advance so you can be prepared."

what?
Chinese military industry?

My small paper has attracted such a huge thing?

For a moment, Xu Ling was so shocked that he couldn't speak.

　The next chapter will cover the content related to China's military industry. I have not been exposed to it myself, so the content I write may be a bit presumptuous and inconsistent with reality. Please understand what I want to express, and please don't take it too seriously.
