The old man has a very unique artistic unkempt hair, but with that serious and dedicated old face, everyone who has seen him can't help but want to salute.

He is an expert-level professor, or a professor-level expert, anyway, mathematics and physics, which has tormented countless young talents since ancient times, is like a children's book in his hands.

He is the professor Sun Han who countless students love!

Professor Sun looked at the students in the class seriously, nodded slowly, his old face warmed up, and said lightly: "Today we are going to learn a new chapter, this chapter is not much in content, and it is extremely practical, and you will often use it in your life in the future." ”

After Professor Sun finished speaking, he turned on the settings in front of him, connected to his e-textbook, and then the electronic screen in front of each student in the seat was displayed.

Macro Integrals!

"Ouch, my mother! Finally, it is time for the macro integral that the dead do not have to pay for their lives. The students in the classroom began to discuss, shaking their heads and sighing helplessly.

Professor Sun was very pleased to see that the students were so active in a new course, and then squinted his eyes and nodded, and said: "This macro integral, which has been expanded from the basis of calculus through the introduction of Vickers, has been developed for tens of millions of years before it has been completed, this is a very important subject, and if you become an ancient martial arts mecha pilot in the future, this is a subject that must be passed." ”

"Professor Sun, do I have a problem?" Ji Xiaoyu asked curiously, and when he heard him ask, countless pairs of eyes poked over, and the flirtatious taste in his eyes was very strong: "Do you still want to be familiar with Professor Sun before you go to bed......

Ji Xiaoyu, as the focal point of the entire Super Star United Academy, has to be careful with everything he says and does, because there are countless pairs of eyes staring at you at any time. You have to go to the toilet to carefully observe whether anyone is following you, and if you spit casually, you may be taken to the laboratory by an ignorant detective for testing, and you may be able to find the strongest evidence of a certain JIAN murder (you can also find JIAN murder evidence in your saliva, is this detective a second goods?). ）。 And the most terrifying thing is the power of gossip implied in the light of ordinary people's eyes, and one is burned to ashes without paying attention.

"Huh." Professor Sun sorted out the equipment in front of him, smiling very easily, he didn't expect that there were students asking questions, how long, it has been a long time since I heard students ask questions, or it is more appropriate to say that there have been no students talking to him for a long time, Professor Sun almost burst into tears, and then half a day before he calmed down and said happily: "What is the problem, you say, you say." ”

Ji Xiaoyu thought for a moment and said seriously: "First of all, the first question, we are in the nuclear crystal class, and we will take the road of nuclear crystal in the future, and it has nothing to do with what ancient martial arts mechas, armored cores, and gundams have nothing to do with it, why do we have to learn mathematics and physics that is not only rare to die, but also hurts brain cells, and finally creates countless bald heads?" ”

"Well, that's a good question." The old professor smiled, but Ji Xiaoyu was confused.

The old professor continued: "Mathematics and physics are indeed the most brain-hurting of all subjects, and this is also because of its difficulty, so this is an extremely advanced science." ”

Ji Xiaoyu's face was black, it seems that Professor Sun's mathematics and physics have reached the pinnacle, resulting in a lack of cells in the brain, isn't this the answer to the question, and then continued: "...... Well, Professor Sun, I also deeply understand what you said at this moment, this mathematics is really hurtful to brain cells. ”

Then he was curious: "Then I still have a question, I think for us ordinary people, as long as we learn the most basic and simple calculus, probability theory or something, we can meet our daily life, why do we need everyone to learn such a sad advanced mathematics?" ”

"Hehe, I'll correct a little first." The old professor said with a smile, "Calculus and probability theory are only a little useful in today's world when young children are at home, these are too simple and basic, and they are useless in daily life." ”

Then the old professor continued: "Well, the question of why I want to study mathematics and physics is still quite profound, and the philosophical ideas in it are also known to me when I met an old friend a long time ago. Professor Sun nodded at Ji Xiaoyu, seemingly satisfied with this question.

"There's philosophy in there, too?" Ji Xiaoyu was really a little confused when he heard Professor Sun's words.

"I also asked my old friend at the time, and then I learned the real answer from him." Professor Sun said seriously, as if he was still reminiscing about the scene at that time.

Ji Xiaoyu saw Professor Sun's very enjoyable appearance, and seemed to be more and more interested in this question, and couldn't help asking, "What is the real answer?" ”

Professor Sun sobered up from the aftertaste, a warm smile appeared on his old face, looked at Ji Xiaoyu and said, "The answer is that the nature of the world determines that each of us must learn this advanced mathematics. ”

Seeing Ji Xiaoyu's stupid look, Professor Sun smiled and continued: "This is just like people have poor, average, rich, and a very small number of rich people, this is determined by the nature of the world, and for example, people have stupid people, ordinary people, smart people, and very few geniuses, this is also determined by the nature of the world, you understand?" ”

"Genius?" Ji Xiaoyu's eyebrows twitched, and then he laughed, "A genius like me is a genius?" ”

One sentence disgusted the students before and after, and threw a contemptuous expression over one by one, what was in his head, and Professor Sun heard a "genius" after explaining for a long time.

Hearing Ji Xiaoyu's speechless answer, Lu Ping grinned with a smile, and couldn't help but bury his head under the desk and sit on the seat and laugh, looking very obscene, such a sunny young man seemed to be polluted by Ji Xiaoyu and was not saved.

And Xiao Mengjie next to Ji Xiaoyu was just covering her mouth and smiling, but when she saw Lu Ping's obscene bear appearance, she couldn't help but bury her head and follow Lu Ping to hide under the table and sift the chaff......

However, what the other students were doing, Professor Sun didn't look at it at all, and only stayed on Ji Xiaoyu, and he was very serious about this question: "...... Well, do you understand? ”

"Oh, I see, I'll draw inferences, there are also simple subjects, general subjects, and difficult, extremely difficult subjects, so this mathematics and physics is the extremely difficult subject, right?" Ji Xiaoyu laughed deterringly, completely ignoring the ridicule of other classmates at all.

"Well, yes, you're right."

"Haha, so whether we want to learn it or not, this most difficult subject will definitely exist, even if mathematics and physics are canceled, there will be other mathematics and literature, etc., anyway, there will definitely be a difficult subject." Ji Xiaoyu's smile added a little more, "So I'm a genius." ”

Hearing Ji Xiaoyu say such embarrassing words without changing his face, the female classmates laughed like flowers one by one.
