A few minutes later, the professor went back and forth, put two long objects on the ground opposite a group of students, glanced around, and said, "I've kept you waiting, and now it's time for the lecture to begin." Please stop all kinds of small movements, do not talk to each other, and listen carefully. ...... The monkey, the monkey, you two shut up, and the spider and the little fat man, you two too. ”

The name of the person, the shadow of the tree, Zhang Qian is famous in the world, and it is rumored that he has always been not very good-tempered, after saying this, the students decisively stopped talking.

Oh, yes, it looks like it's starting to smell like a clean street tiger.

Seeing that he had trained the students honestly with one sentence, Zhang Qian nodded with satisfaction: "Very good, students must look like students, dare to be disobedient, I will not stay grounded in the classroom, be careful of being beaten." ”

...... What a murderous professor.

A bunch of young people are a little speechless, this professor is too dick, and it's really like the rumored rotten temper.

They couldn't help but secretly rejoice, fortunately they didn't fight him just now, otherwise...... What if the professor is serious?

Under the deterrent effect, these naughty monkeys not only shut up, but also straightened their chests one by one, and their seriousness was comparable to that of the three good students in China.

"Good. ”

The professor was particularly satisfied: "First of all, let's talk about the course schedule. As you know, as a visiting professor at our university, I only have one class a week, so I don't talk to you about the things in the textbook, I don't have that time. ”

After the opening remarks, he lowered his tone a few points and said mysteriously: "Let's learn something fun and interesting." Now, who can guess what this thing is in my hand?"

He was holding a long object about three meters long in his hand, the whole gray was not slippery, very inconspicuous, and because the outer packaging was painted, he couldn't tell what material it was at all.

Originally, it was difficult to guess this kind of thing without a beginning or an end, without a hint.

However, young people in this age group are often very interested in quizzes, and many people raise their hands based on their first impressions, regardless of whether they have a factual basis or not.

"Professor, I know what it is, it's an incomplete profile of a new alloy water pipe!"

"Nonsense! This is clearly a model maglev train track!"

"Haha, a bunch of stupid people, you all guessed wrong, this is simply the concave bar of a CNC machine, I bet, absolutely!"

"Poof, do you say yes? Then I said it's a feeding trough for a small farm, do you think it looks like it?"

"That's right, I think Christine is right. ”

“......”

Seeing a group of classmates chattering and nonsense, Steven, a forward on the varsity football team, felt embarrassed.

The big man couldn't help but stand up, and instantly suppressed the other voices with a huge volume: "If you don't understand, don't talk nonsense, you will be laughed at!" Professor, let me answer this question. ”

Seeing that there was already such a person who gave face before, it was good that there was no cold scene, for this big classmate with such a high score, he had nothing to do, and was about to nod his head in approval...... I didn't expect to see a little fat man also stand up, and because he was too short, he was jumping up and down very happily, raising his hands high......

Professor Zhang couldn't help but twitch the corners of his mouth slightly, and said, "Little fat man, put your hand down, it's none of your business." ”

"Oh~. ”

Zhang Xiaolei boasted with a small face, and sat down very aggrieved, not angry in his heart: Professor Dad is special!

After suppressing the little fat dun, Zhang Qian motioned for the big classmate to speak.

Steven was already a little impatient, and after getting his approval, he said very confidently: "This should be an electromagnetic orbital kinetic energy weapon!"

"Huh? Ice dog! You guessed it right. Tell me how you guessed it?"

It's really unseemly, I didn't expect this big guy to be a scholar, Zhang Qian was a little curious.

Steven resonates: "I think it has two adjacent tracks, and the tracks are surrounded by half-open ring grooves, so the inside of the bold groove is actually a coil. Then, the results are already obvious. ”

"Good! Observant, that's good. Scientific research is to make bold assumptions and carefully verify, this student has the potential to be a scientist, I am optimistic about you. Sit down. ”

Probably never been praised by the teacher before, 1.95 meters Steven was praised by the professor for a few words, the giant turned slightly red, couldn't help scratching his scalp, and sat down as if nothing happened.

After a short contact, Zhang Qian was indeed a little impressed by the rugby player, and after nodding slightly, he affirmed: "This classmate is right, this is indeed an electromagnetic orbital kinetic energy weapon." So you know, we're talking about electricity and magnetism today. ”

"First of all, you need to know the basic relationship between electricity and magnetism, and say that they are two sides of the same coin, rather than light and dark twins. In modern divisions, they are one of the four basic interacting forces. ”

Speaking of this, the Internet celebrity spider man raised his hand and said, "Professor, we know this, we have learned it in the seventh grade." ”

Ahem...... Do you talk like that? It's just not a face-saving thing.

Zhang Qian did not reprimand him for being unruly, but said with a smile: "This classmate, next time you want to speak, remember to get the teacher's approval before you can speak." ”

While secretly keeping accounts in his heart, but not showing it on his face, Professor Zhang still nodded kindly: "Since this has been mentioned, then you must already know what 'magnetic field wire cutting', 'Abe's law', and 'Faraday's principle' are...... , figuring out the current, voltage, resistance, ...... And so on and so forth, right?

Well, let's not talk about theories today, let's take a look at the specific application effect of using horizontal Abe force to continuously superimpose energy.

I need a volunteer, a little stronger, who of you will come?"

Huh? Can you let us play?

This is the legendary electromagnetic railgun!

The students were a little excited.

There is no shortage of hot weapons among the people of the United States, but this kind of high-concept weapon is the first time everyone has seen it, and now it can be operated in person?

That's polite!

"I'm coming! I'm 182 pounds!" Steven raised his hand to the top and glared at a pair of bull's eyes, shooting terror in all directions.

This kind of gangster style is really useful.

was fooled by him like this, and many competitors who were originally very enthusiastic suddenly died down, and there were few left, which made the atmosphere of the scene drop to freezing point.

Peter Parker was not convinced, and stood up and smiled disdainfully: "Hehe, Steven, you probably misunderstood something, when it comes to strength, who can compare to me Spider-Man? ”

"You ......"

This kind of person dared to lose face in front of everyone, which made the big guy angry, but in the end he coaxed.

"Okay, you're the one you're waiting for, ahem, I mean, Peter-san. ”

Zhang Qian saw that the little spider could stand up by himself, and immediately stuffed things into his arms, and explained: "Have you ever shot a gun? Yes? That's good, you just treat this as an AK to use, see if it's a crosshair, this is Shangtang insurance, here is the energy shift, seeing that you are so thin, I advise you to adjust to the lowest gear." ”

"Hehe, Professor, you probably don't know you're underestimating me. ”

Peter was very unconvinced, and secretly said in his heart: I will turn up to the maximum gear to see what can be done to me......
