[1] Akiyama Sora

(Real World, Friday, April 10, 2015, Night; Duplex Apartment, Sora Akiyama, Kyoto)

"I'm back, Jiyin. ”

Sora Akiyama closed the door behind him and walked into the living room with his briefcase. Tomoon Nanamiya, wearing an apron, is busy in the open kitchen, and the smell of appetizing food wafts through the air.

"Sora seems to be busy lately. The girl looked at him with a smile as she stir-fried the vegetables on the pan, "It's always been so late these days. ”

"Aha, after all, as the leader of the laboratory, it doesn't seem good to sneak away at a critical moment. ”

Sora Akiyama said as he put his briefcase on the shelf next to the workbench, then took off his coat and went to the bathroom to clean his hands. During this time, the research in the laboratory has progressed to a critical period, although he has always opposed the practice of working overtime, but in the face of all kinds of unpredictable problems in the process of experiments, he still has to stay and solve them.

Another thing that bothered him was that his course on "Algebraic Topology, Graph Theory and Brain Connectors" did not welcome students from the medical and biology departments as expected, and the few applicants were mostly math majors.

How can these people be scared away by the name of the course? In vain I have been working in the mental network for so long, and the course has been designed to be simple and in line with human cognitive habits.

Back in the living room, Sora Akiyama looked at Shichinomiya Tomoon who was cooking, and his heart suddenly moved.

"I said why did I suddenly think Zhiyin-chan was so cute.,It turned out to be the animation of that parallel world.,I found that this wife's full of Zhiyin is too contrasting and cute.。 ”

"You...... Empty!"

The embarrassed girl put the last dish on the table, then ripped off her apron and threw herself at him. He grinned evilly and hugged the girl with teeth and claws, letting the other party scratch at him like a cat, and finally lazily put his arms around his neck and leaned into his arms.

"Well, if you don't eat it, it'll be cold. ”

After rubbing for a while, Nanamiya Zhiyin came out of his embrace. This girl's craftsmanship is not bad, the heat is just right, the meat slices are tender and the vegetables are crisp, and the thick sauce is not greasy at all. After dinner, they threw the rest of the dishes into the dishwasher and snuggled up to each other on the couch.

"Xu Mingshan recently wrote a Cthulhu fairy tale?"

Sora Akiyama fiddles with the data terminal in his hand and reads a short story called "Nightmare of the Imaginary Land" with his lover. In all fairness, the Cthulhu-style horror atmosphere is pretty good, but ......

"Meow meow meow, a friend who is a cognitive scientist? is still noncommittal, and seems unwilling to get too involved in this past?

"Bhaha!"

Nanamiya laughed and patted him on the shoulder.

[2] One side passes

(Forbidden World, April 26, 2013, Friday, morning; School City, Ruiyun Elementary School)

More than half a month has passed since the attack. Listening to the director of the alien named Sora Akiyama, the follow-up investigation did not find valuable information, and the mind-reading ability was also deflated by the group of cloaked monsters, which cannot but be said to be an unpleasant thing.

However, it is worth thanking that Mikoto Misaka's ability level seems to have broken through to Level 4 under that sudden stimulus. Due to the improvement of her ability beyond expectations, the other party did not participate in the activities of the physics department during this time, but went to the institution in charge of her ability development as soon as school was out of school to check.

Fang Tong thought so, and followed the students up the stairs. At the door of the class, Teacher Liding stopped him.

"Student Yi, Mr. Hagiya in the science class is not feeling well, can you take today's class?"

Hearing this, he couldn't help but be stunned for a moment. In this case, it is the teacher who substitutes the teacher, not a student, although he is confident that he can teach this basic physics knowledge without preparing the lesson.

"It was supposed to be done by another teacher, but unfortunately another teacher also took a leave of absence due to injury. If you are a student, it must not be a problem to cope with this level of teaching, right?"

Since the other party has talked about this, and one party has no intention of refusing, he immediately said that he can substitute for a class. The guards of the school city are volunteered by teachers.,It's not inconceivable to get injured in the event of a sudden accident.。

Back in her seat, Mikoto Misaka had already taken a seat first. When the curious girl saw him, she immediately leaned over and asked:

"What's the matter? Teacher Liding seems to have stopped you at the door just now?"

"Said that Mr. Hagiya was not feeling well, so he asked me to take his class. Speaking of this, Fang Tong remembered that he was going to stand in front of the podium in the third class, and he couldn't help but feel a little nervous, "It seems that the guard encountered something while on duty and was injured." ”

"Well, it's really hard for the teachers who volunteer to be guards...... But you're going to give us a lecture!" the brown-haired girl patted him on the shoulder with a big grin, "Hmph, I remember someone who never listened. ”

One party was speechless for a moment. The level of this school is quite good, and Mr. Hagiya, who teaches science and science, saw that he had already taught himself the university physics course, so he simply let him go to class and study on his own, as long as it did not affect the other students. However, Mikoto Misaka, who is at the same table, can see what he is doing when he turns his head slightly, and it is impossible to say that it has no effect at all.

The class bell rings. The two classes passed imperceptibly in full attention, and after the second class, it was finally his turn to take charge of the third class. He felt his heart pounding, a nervous emotion rising from the bottom of his heart, and his limbs became a little stiff due to muscle tension.

"Hee-hee, are you nervous?" As if sensing the change in his face, Mikoto Misaka suddenly grabbed his hands and looked at him with shiny brown eyes, "Look at me, relax...... You can do it. ”

Fang Tong looked at the girl in front of him, and somehow felt very relieved, and his tense body gradually relaxed. But then he realized that the distance between them seemed to be a little too close, and he couldn't help but blush. When the other party saw his expression, he also remembered something, hurriedly let go of his hand, turned around and left him with a back.

Towards the end of the recess, Mr. Liding walked into the classroom, briefly told the students in the class about letting him substitute for the class, and then waved his hand away from the podium, leaving him alone to stand there.

"That's, that'...... Mr. Hagiya is not here today, so I'll give you this lesson. ”

Perhaps his expression was a little strange due to inner tension and deliberate suppression, and a slight sneer came from the corner of the back row, followed by whispers from ear to ear everywhere. He didn't know whether to stop it or just continue the lecture.

"Okay, everyone be quiet, Fang Jun was also temporarily asked by Teacher Liding. Fortunately, the class leader Lishi Yanfan relieved him in time, "Classmate Yifang, maybe I should call you teacher now, please give me more advice." ”

"Ah...... Well, please give me a lot of advice. This class is about simple circuits......"

Focusing on the knowledge structures in his mind, he quickly entered the state and forgot about the nervous feelings.

Let's start with this example. As shown in the figure, two resistors R1 and R2 are connected in parallel, and the input current is I, find what are I1 and I2. I believe that all of you who have completed your summer homework on time know that you can solve the equation as long as you add Ohm's law when the voltage is equal when parallel. ”

"But what I want to mention today is the principle of minimum action. Yes, this part is not in our textbook, but I think it is important for several capable people in our class. As for students like me who have not yet awakened the ability, I also hope that you can listen patiently, maybe one day you will be able to build your personal reality?"

"I'm sure everyone remembers what superpowers are, which is a major breakthrough in the theory of quantum mechanics, through the 'reality that belongs only to oneself', that is, the reality observed through deliberately distorted calculus and judgment ability, so that the extreme microscopic world probability will have unnatural changes, so as to create certain phenomena. Rest assured, we don't need to learn that much math right now. ”

"Back to the previous question. If we consider it from the point of view of 'the values of I1 and I2 are such that the thermal power P is minimized', then according to Joule's law, there is a ...... To calculate the minimum value of P, we find derivatives on both sides of the above equation...... Oh, and this is not yet learned, in the way we have already learned, which is to take the known R1, R2, and I as constants, write I2 in the form (I-I1), and then find the minimum value according to the properties of the quadratic function. ”

This principle is not a hypothesis, but a basic fact based on human reason based on the phenomena we observe and the description of these phenomena. Of course, this also means that this principle may not be true in some different dimensions, and interested students can read Hume's book. ”

Speaking of this, Fang Tong suddenly remembered his ability developers - they didn't slip a little, but they were indeed different dimensional creatures.

Let's do some simple experiments...... Misaka-san, please don't use your abilities casually. ”

Finally finished this class, and the party who came back to his senses only felt soft, as if those suppressed emotions were released after relaxing. However, when he thought that he had done well in his first public speech, he felt very happy and proud of himself.

"I'll just say, you can do it!"

"That's amazing, Fang Fangjun! I usually don't talk much, but I didn't expect to be so fluent when lecturing!"

The praise from his classmates made him blush a little, but this lively and warm atmosphere was something he had never experienced in the [Special Ability Institute] before. It's a good feeling, he thought to himself, thank you.
