I Am the President of the University

"Newton's first law and Newton's third law will not be introduced here, and Newton's second law will be mainly introduced here.

A particle M with a mass of m and a velocity of v at a certain moment, then its momentum is mv. If the net force it receives at a certain moment is not zero, then its momentum will change, and we have F=d(mv)dt.

Note that in high school, we usually regard mass as a constant, that is, F=m·dvdt, but in physics we may encounter situations where mass changes, as shown in the following question..."

The physics teacher on the podium was talking with great interest, while Shi Ze, who was under the stage, was already shaky, just like kowtowing, his head sank for a while, and then lifted up when it was about to hit the table.

Zhang Lei, who was standing by, was speechless. He patted the other person on the shoulder and advised: "Aze, don't kowtow, don't force yourself, just go to sleep."

"I don't... I also have to study hard..." After being called by Zhang Lei, Shi Ze seemed to be more alert. He looked at Zhang Lei sleepily, like Mo Yang who played games all night, "College physics is really difficult. Why do we computer majors have to study physics?"

"If you ask me, who should I ask? It's hard for me to listen too!" Zhang Lei also replied, and continued to focus on the teacher, for fear that he would be distracted for a while and then not understand.

"Now I will give you a question. Just treat it as a course assignment and hand it in at the end of get out of class." The middle-aged teacher with round-frame glasses on the stage paused and added with a smile, "It will be counted into the regular score."

"No, teacher, it will kill me!"

"Physics is so difficult, teacher, please be a human being!"

"I regret applying for computer science now. God knows I will have to study physics in college!"

A burst of complaints rang out, and the physics teacher listened to these complaints and wrote the questions on the blackboard more diligently.

After a while, the questions were written, and the physics teacher clapped his hands and encouraged: "Students, you can start doing the questions, come on~"

Some sleeping students were woken up by their roommates, and then looked up at the questions on the blackboard and were instantly stunned.

Who am I?

Where am I?

What the hell is written on this blackboard?

Why can't I understand it!

Zhang Lei also had some difficulty looking at it, biting his nose and didn't know how to write for a while.

There seemed to be some thoughts in his mind, and the knowledge points were like pearls scattered on the beach, just missing a line to string them together.

But sometimes, it is hard to find this line.

"Oh, physics is so difficult, I hope I don't fail this course." I heard that the most failed courses in college are physics and advanced mathematics. I originally wanted to get more than 90 points in all courses and strive for a high GPA, but when I encountered this physics course, he was shocked!

The sound of "swish!" writing was particularly clear in his ears. Zhang Lei turned his head and saw that it turned out that Zheng Tianyu had already started to write and answer the questions.

"Tianyu, can you do this question?" he couldn't help asking.

"Is this question difficult?" Zheng Tianyu answered without raising his head.

Zhang Lei, Shi Ze, Chen Chu and other five people in the dormitory suddenly turned pale.

This question is not difficult, so aren't the five of us mentally retarded? ? ?

"Isn't this question difficult? Let me see how you did it." Zhang Lei said as he looked over. After looking at the formulas in the first two lines of Zheng Tianyu, he suddenly understood it and murmured, "Oh, so that's how it is. I know how to write it!"

It was as if he had suddenly realized it. After reading Zheng Tianyu's beginning, his thoughts were instantly cleared and he began to write.

"Let me see too." Shi Ze looked at Zhang Lei's performance, his neck stretched out, his mind almost sticking to the homework paper.

"Aze, don't get too close." Zheng Tianyu frowned.

Shi Ze's head came back to its place, scratching his head with one hand, and fell into self-doubt.

"Why did Zhang Lei understand it after just one look, but I still looked confused after reading it?"

"Ah..."

A long sigh sounded.

The gap between people is indeed greater than that between people and dogs!

Zheng Tianyu was very comfortable writing. He found that it was much easier to understand the class in the classroom than the online class in the dormitory. Of course, this was the effect of the +50% comprehension increase of the system teaching building.

With his potential value of 87 (first-class talent) and the buff of the teaching building, he could understand even a difficult course like university physics as soon as he heard it. It was not difficult at all.

He even wanted to ask the teacher to increase the difficulty by one level!

In ten minutes, the questions were finished.

As soon as he finished the homework paper, Shi Ze took it away with a smile to copy it. It was obvious that Shi Ze had given up the idea of ​​doing the questions.

Looking around again, it seemed that everyone was struggling with the questions with a sad face.

Shaking his head, Zheng Tianyu picked up his mobile phone and was about to check Zhihu when a WeChat @message attracted him.

" @All members of the Guanghua Security Center app have been put on the shelves of the four major mobile phone manufacturers and can be downloaded and viewed!"

The mobile phone provided by the studio was used for testing. The installation package cannot be exposed privately before it is put on the shelves, even if it is their mobile phone. After all, the mystery will be gone if it is leaked.

"Finally I can download it."

Zheng Tianyu exhaled and opened the Huaxing App Market. Sure enough, the mysterious banner before turned into a promotional pattern of Guanghua Security Center.

Clicking it again, Zheng Tianyu was stunned by the content of the picture.

"Fuck, the download volume has already reached 2,000 times!"

It has only been on the shelves for a short time!

It seems that the promotion efforts are really powerful!

When downloading, looking at this familiar school badge, even Zheng Tianyu, who personally participated in the research and development, couldn't help but smile. When discussing the app display icon, the principal directly decided to use the school badge... Everyone was speechless, but when I think about it, it seems... Not bad?

How honorable is this!

Because the software is not big, it does not take long to download. Zheng Tianyu feels more relieved after installing the software.

Regarding Guanghua Security Center, Zheng Tianyu knows better than outsiders how awesome this software is! Of course, the main reason for this is the importance of the core code written by the principal. Otherwise, if they are a bunch of college students, it would be good if the programs they wrote can run normally. Do you want more approval?

ps: Mobile phones are really the biggest enemy of self-discipline. Time passed in a flash and I failed the 3,000-word challenge...
