Chapter 429: Who is the Professor?

The surrounding students saw the angry expression of the physics professor, and they were not stunned, and they all looked at the GI and the fat man, and the physics professor was already a little angry when the GI came in before, but he didn't say anything. net

After all, the GI is his student, even if the GI just pays to come here to get a diploma, he is not qualified to say anything, this is a university, not a middle school, let alone an elementary school, and the physics professor may be treating the GI like a child.

But even if the GI didn't study and slept on the table, it didn't matter, the GI was still talking to another classmate on the side, which made him very depressed in the lecture, and the physics professor had already looked in the direction of the GI and the fat man several times.

It's just that the soldier and the fat man ignored him, so that the physics professor was completely mad, and he couldn't help it, and planned to drive the two out, and when the fat man heard this, he hurriedly got up from his seat like a child who made a mistake.

However, the GI sat there quietly, these days the GI had finished his university courses, and even learned the languages of dozens of countries, and the GI found that his memory had become very strong since the last time he recovered his memory.

As long as he wants to learn, he can learn it at one time, and it is the kind that knows everything, and for his learning ability, as well as his super memory ability, the soldier can't find a reasonable explanation, "Professor Physics, what's your problem?" ”

Under the gaze of everyone, the soldier raised his head and looked at the physics professor on the podium, and the physics professor on the podium saw the soldier actually asked him this sentence, and three black lines appeared on his forehead, what is your problem? Is this guy provocative?

The angry expression on the physics professor's face He didn't care, and the soldier didn't want to embarrass the physics professor, he just wanted to come to the school to have a good night's sleep, and nothing else, but the physics professor didn't think so, he regarded the soldier as the son of a big family, and the soldier's lazy attitude turned into arrogance in his eyes, and the physics professor said with a gloomy face, "Lai Dabing, if you decide that I can't give a good lecture, you can leave directly, you don't have to be here!" ”

"Professor, don't look down on yourself, your lecture is really good, and I'm listening very carefully, it's just that I've completely learned the knowledge you're talking about, so I..."

The physics professor's face is getting more and more ugly, this guy is strong! But soon the physics professor regained his composure and said, "Since you said you learned what I taught in this class, then explain to me the example I am talking about." ”

The people around them couldn't help but be stunned when they saw the physics professor say this, and the fat man standing on the side hurriedly closed his mouth, not even daring to speak, but no one expected that at this moment, the soldier actually stood up, walked to the podium, and said.

"Professor, you have been teaching for so long, now you take a break, sit down, whatever you ask, I can answer you, this half class, I will be the teacher." The GI was bored and planned to pass the time by posing as the teacher for half the class.

The physics professor didn't think that the GI would be so rampant, he would answer when he said he would, and even have to teach, under the eyes of everyone, the physics professor didn't seem to be angry, but smiled and said, "Okay, as long as you answer me a question." ”

"An acrobat can throw 5 balls to a height of 3.0 meters one by one, so that these 5 balls are kept in the air, one, determine the time interval between two throws in succession, two, find the height of the other balls when a ball is about to fall into the hand, and set the ball in the hand to stay for a negligible time, answer my question, if it can be correct..."

The fat man standing behind his face was full of helplessness, and he secretly said in his heart, Brother Bing, even if you are bored, you don't have to play like this, physics is not so easy to learn, you go up now, and teach the whole class, isn't this your own moving stones?

But no one thought that before the physics professor could finish speaking, the soldier didn't think about it, so he directly picked up the chalk and said, "One, for the sake of simplicity, set the height of the acrobat's hand to 1m, one, the easy ball from being thrown to the time of falling 2 √ (4mg) is about 1.277s, and after he throws the first ball, he will have to throw 4 more, so dividing this time into 5 parts is an interval of .255s." ”

When he said this, the soldier had already written down what he had just said on the blackboard, and everyone couldn't help but gasp when they saw this scene, but at this time, the soldier continued, "The speed when throwing is easy to know is 6.26ms, so calculate the height with .255s as the time interval: (6.26ms-(9.8ms^2)*.255s2)*.255s+1m=1.28m+1m=2.28m, The following can be extrapolated to 2.92m, 2.92m, 2.28m, I don't know if I'm right? ”

After finishing speaking, the series of methods had been written on the blackboard by the GI, and when they saw the answers on the GI's blackboard, the students present couldn't help but be stunned, and several students began to take out their pens and calculate whether the answers the GI said were correct in their notebooks.

But at this time, the physics professor who was sitting in the reasonable place was completely speechless, and he stared at the soldier with wide eyes, in fact, he had not passed this question just now, but a question that he had improvised according to the course he had said before.

In less than half a minute, the physics professor also calculated the result, his eyes were full of surprise as he looked at the soldier, and secretly said in his heart, does this kid really understand these boring and boring physics, because the answer that the soldier said earlier is completely correct!

Good boy, he really knows physics, and he can say accurate answers in such a short time, which makes the physics professors a little surprised, but because of what the GI revealed, he became interested in the GI, he asked this time.

"Yes, Lai Dabing, you answered very correctly, and then you are answering this question, the particle is moving forward along the x-axis, the acceleration a=-kv, k is a constant, let the velocity from the origin point be v, and find the equation of motion x=x(t)."

The soldier heard the physics professor asking a question, he showed a rare smile on his face, at this time outside the classroom where the soldier was, several teachers and classmates passed by, and saw the soldier standing on the podium lecturing and lecturing, and the physics professor asked questions below, they stopped curiously, looking at all this suspiciously, they wanted to see what was going on, the soldier stood on the stage, his face was very calm, and said with a smile, "Professor, I think you are wrong, now I am the teacher in half the class, what should you call me?" ”

No one expected the soldier to be so fierce that he would let this physics professor call him a teacher, and even a few teachers and some students outside the classroom couldn't help but push open the door, walk into the classroom, and sit in the back row of the classroom.

They were very curious, how could this be so virtuous, that the physics professor would call him a teacher, and the physics professor never thought that the soldier would mess around like this, but he was not angry, and said with a smile, "Then please ask Mr. Lai to answer this question for us." ”

When the students present saw that the physics professor really called the soldier a teacher, three black lines appeared on their foreheads.

However, the soldier didn't pay attention to the stunned gazes of those people, he picked up a piece of chalk and said lightly, "Classmate Huang, your question is very simple, now you can listen to me to help you break it down." ”

Hearing the soldier's words, three black lines appeared on the foreheads of everyone present, their eyes were full of astonishment and stared in the direction of the soldier, the soldier called the physics professor Huang, I'm afraid that no one is stronger than him in Guangcheng University, right?

Under the stunned expressions of everyone, the soldier quickly decomposed, "According to the meaning of the title, there is an equation a(t)=v'(t)=-kv(t), and v(t)=e^kt)+c1 is solved, and when t=v=v, c1=(v)-1, so v(t)=e^kt)+(v)-1, and v(t) is integrated as x(t)=e^kt)+[(v)-1]t+c2, because from the origin, t=s=, c2=-1 so x(t)=e^kt)+." [(v)-1]t-1, Mr. Huang, I don't know if I'm right? ”

After the people present heard what the soldier said, they were calculating the soldier's answer this time, and even the physics professor was silent for a while, secretly calculating the answer that the soldier said, and soon the physics professor smiled bitterly, "Your answer is right." ”

Other physics students, who are better at physics, haven't finished the math yet, when they hear the physics professor's words, three black lines pop up on their foreheads, and the answer is right? Could it be that this soldier in front of him really knows physics?

The speed at which the GI could answer in an instant completely shocked them, how much understanding of physics did it take to answer so quickly? Even for people who are generally good at physics, it will take ten minutes to solve it.

But this Lai Dabing actually solved these two questions in an instant, which completely shocked those students who thought they were very good at physics, and they stared at the soldiers on the stage in amazement, 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 the GI, this guy didn't seem to be as bad as he imagined, and the GI's extraordinary reflexes also made the physics professor arouse the physics professor's curiosity.

He asked the soldier to ask a few questions again, slowly from shallow to deep, and even some questions were beyond the scope of the university, even everyone present did not understand what the soldier and the physics professor were talking about, but the two of them asked and answered.

Watching the GI explain on the podium, everyone present was speechless, and even several other teachers were shocked, at this moment they had the illusion that the GI standing on the stage was a professor, and the professor in the audience was a student...

The more the physics professor asked, the more interested he became, and even gradually he began to discuss with the soldiers, asking some topics that other students couldn't understand at all, and those students felt a little confused at this time, as if there was not a professor and a student talking in front of them, but two professors were discussing the difficult problems of physics, and even talking, the two talked about the top ten problems of physics in the world, and the soldiers could still easily answer, as well as explanations, and even theories, which made the students present completely demented, he was really just a student?
