When the students around him saw the angry expression of the physics professor, they were stunned and looked at Dabing and the fat man. When Dabing came in, the physics professor was already a little angry, but he didn't say anything.
After all, Dabing is his student. Even if Dabing just pays money to get a diploma here, he is not qualified to say anything. This is a university, not a middle school, nor a primary school. The physics professor may be taking Dabing as a child.
But even if Dabing didn't study and lie on the table to sleep, it would be fine. Dabing was talking to another classmate next to him, which made him very depressed in his lecture. The physics professor had already turned his eyes to Dabing and Fatty several times.
But Dabing and Fatty actually ignored him and drove the physics professor completely crazy. He couldn't help but plan to drive the two out. When the fat man heard this, he was like a child who made a mistake and hurriedly stood up from his seat.
However, Dabing sat there quietly. These days, Dabing had already finished learning the university courses and even learned the languages of dozens of countries. Dabing found that since the last time he recovered his memory, his memory ability became very strong.
As long as he wants to learn something, he will learn it at once, and it is the kind of one who can understand everything. Dabing can't find a reasonable explanation for his learning ability and super memory ability. "Professor of physics, what's the problem with you?"
Under the eyes of everyone, Dabing raised his head and looked at the physics professor on the podium. When the physics professor on the podium saw Dabing, he asked him this question. Three black lines suddenly appeared on his forehead. What are you having a problem? Is this guy provoking?
Dabing didn't care about the angry expression on the face of the physics professor, and Dabing didn't want to make things difficult for the physics professor. He just wanted to come to the school to have a good sleep, and that was nothing else. But the physics professor didn't think so. He regarded Dabing as the young master of a big family. Dabing's lazy attitude turned into arrogance in his eyes. The physics professor said with a gloomy face, "Class Lai Dabing, if you decide that I'm not good at teaching, you can leave directly, don't have to be here!"
"Professor, don't be too slight on yourself. Your lecture is really good. I listened very seriously. But I have fully learned the knowledge you are talking about, so I..." Dabing said seriously.
The physics professor's face became increasingly ugly, and this guy was rude! But soon the physics professor returned to his calmness and said, "Since you said you learned what I taught in this class, then explain to me the example I am talking about now."
When the people around them saw the physics professor say this, they couldn't help but be stunned. The fat man standing beside him hurriedly closed his mouth and didn't even dare to say anything, but no one expected that at this time, the soldier actually stood up, walked to the podium, and said.
"Professor, you have taught for so long. Now you have a rest and sit down. I can answer you no matter what you ask. I will be a teacher in this half class." Dabing was bored, so he planned to pass the time by pretending to be the teacher in the half class.
The physics professor never thought that Dabing was so arrogant, and he answered as soon as he answered, and even taught classes. Under the eyes of everyone, the physics professor seemed not angry, but smiled and said, "Okay, as long as you answer me a question."
"A acrobat can throw 5 balls one by one to a height of 3.0 meters, so that all the five balls can be kept in the air. First, determine the time interval for throwing the ball twice in succession. Second, find out when one ball is about to fall into your hand, the height of the other balls can be ignored. Answer my question, if it is correct..."
The fat man standing behind his back was full of helplessness. He thought to himself, Brother Bing, even if you are bored, you don’t have to play like this. Physics is not so easy to learn. If you go up now, you will teach the whole class. Isn’t this shooting yourself in the foot?
But no one expected that before the physics professor had time to finish his words, Dabing picked up the chalk without thinking, and said, "One, for simplicity, set the height of the acrobat's hand to 1m, and then the 2√ (4mg) of the ball is about 1.'7s. After he threw the first ball, he had to throw another 4 more, so the time was divided into 5 parts, which means the interval was 0.255s."
When he finished speaking, Dabing had already written down what he had just said on the blackboard. When everyone saw this scene, they couldn't help but breathe a breath of air. However, at this time, Dabing continued, "The speed when throwing is easy to know is 6.26ms, then the height is calculated at 0.255s as the time interval: (6.26ms-(9.8ms^2)*0.255s2)*0.255s+1m=1.(m+1m=2.(m, so the following can be compared to 2.92m, 2.92m, 2.(m, I wonder if what I said is right?"
After saying that, the series of methods were written on the blackboard by Dabing. When they saw the answers on the blackboard, the students present couldn't help but be stunned. Several students began to take out pens and calculate in the notebook whether the answers Dabing said were correct.
But at this time, the physics professor who was sitting in a rational manner was completely speechless. He stared at Dabing widened his eyes. In fact, he had not just finished this question, but a question he made up temporarily based on the course he mentioned earlier.
In less than half a minute, the physics professor also calculated the result. His eyes were full of surprise and he looked at Dabing, thinking in his heart, does this kid really understand these boring and boring physics, because Dabing’s answer was completely correct!
The good boy was really good at physics and could give accurate answers in such a short time, which surprised the physics professor, but because of the soldiers' exposure, he became interested in them, he asked.
"Yes, Lai Dabing, you answered it very correctly. Next, you are answering this question. The particle moves forward along the x-axis, with acceleration a=-kv, k being a constant. Suppose the velocity is v0 when starting from the origin, and find the equation of motion x=x(t).
Dabing heard a question from a physics professor, and a rare smile appeared on his face. At this time, outside the classroom where Dabing was, several teachers and classmates passed by. Seeing Dabing stand on the podium to give a lecture, and the physics professor asked below, they stopped curiously and stared at all this. They wanted to see what happened. Dabing stood on the stage with a calm expression on his face and smiled, "Professor, I think you called me wrong. Now in half the class, I am a teacher, what should you call me?"
No one expected that Dabing was so fierce that he actually asked the physics professor to call him a teacher. Even the teachers and some classmates outside the classroom couldn't help but push open the door, walked into the classroom, and sat in the back seat of the classroom.
They were very curious about what kind of virtues and what could this physics fight to call him a teacher. The physics professor never thought that Dabing would do so randomly, but he was not angry and said with a smile, "Then please ask Teacher Lai to answer this question for us."
The students present saw that the physics professor really called Dabing the teacher. Three black lines appeared on their foreheads. Lai Dabing was playing a bit big, and he was a professor!
However, Dabing ignored the shocked gazes of those people. He picked up a piece of chalk and said lightly, "Student Huang, your question is very simple. Please listen to me to help you solve it."
Hearing Dabing's words, three black lines popped up from everyone present's foreheads. Their eyes were full of surprise and stared at Dabing's direction. Dabing called the physics professor Huang. I'm afraid no one in Guangcheng University is stronger than him, right?
Under the stunned expression of the crowd, Dabing quickly decomposed, "According to the question, there is equation a(t)=v'(t)=-kv(t), the solution is v(t)=e^(-kt)+c1, and when there is t=0, v=v0 gets c1=(v0)-1, so v(t)=e^(-kt)+(v0)-1, the integral of v(t) is x(t)=e^(-kt)+[(v0)-1]t+c2, because starting from the origin, t=0, s=0, get c2=-1, so x(t)=e^(-kt)+[(v0)-1]t-1, classmate Huang, I wonder if what I said is right?"
After hearing Dabing say it, they calculated Dabing's answer this time. Even the physics professor was silent for a while, secretly calculating the answer Dabing said. Soon the physics professor smiled bitterly, "Your answer is correct."
Other students who are good at physics have not finished their calculations yet. When they heard the physics professor’s words, three black lines suddenly appeared on their foreheads. The answer is correct? Could it be that the soldier in front of them really knows physics?
The speed of the soldiers' answers in an instant completely shocked them. How much knowledge about physics is required to answer so quickly? Even people with better physics will take ten minutes to answer.
But this Lai Dabing actually answered these two questions in an instant, completely shocking the students who thought they were very awesome in physics. They stared at the soldiers on the stage in a daze, and they didn't know what to say at this time.
Even the physics professor was the same. His eyes were full of surprise and stared at Dabing. This guy seemed not as bad as he imagined. Dabing's extraordinary reaction ability also aroused the physics professor's curiosity.
He once again wanted Dabing to ask a few questions, slowly from shallow to deep, and even some questions went beyond the scope of the university. Even everyone present did not understand what Dabing and the physics professor were talking about, but the two of them asked and answered questions.
Seeing Dabing explaining on the podium, everyone present was speechless, and even the other teachers were shocked. At this moment, they had an illusion, as if Dabing standing on the stage was a professor, and the professor in the audience was a student...
The physics professor became more and more interested. Gradually, he began to discuss with Dabing, asking some topics that other students could not understand at all. The students felt a little confused at this time, as if they were not talking to a professor and a student, but two professors were discussing physics problems. As they were even talking, the two talked about the top ten problems in world physics. Dabing could still easily answer, explain, and even theory, which made the students present completely dementia. He was really just a student?
