Sagawa Yan originally firmly believed that all things are composed of various particles, such as electrons, atoms, quarks, and so on, which are infinitely divided into particles.

But he crossed over.

This forced him to abandon the particle theory and think about string theory.

"String theory requires a high level of mathematical ability to understand and apply, let alone superstrings. I don't think I can even think about mathematics without lv3."

It is precisely because there is no experiment to support the proof that all superstring theories can only be derived mathematically, and the entry requirements are harsh.

Yan Sagawa slowly wrote down the topic on the manuscript paper, quantum field theory and many-body problems.

Once the topic is determined, this important first step is determined.

Then he started to focus on this topic, fully mobilized the relevant knowledge in his mind, and wrote a line of discussion on the manuscript paper.

"Quantum field theory is an important branch of quantum mechanics, and many-body problems..."

It was quiet in the study.

There are only three people who are eager to learn.

The time soon came to more than 9 o'clock.

The effects of NZT-48 started to wear off.

Xiaolan Yuanzi and the two recovered from their study state one after another. "so tired."

Both of them felt very tired after taking NZT-48 for the first time.

But the two who looked at each other saw excitement in each other's eyes.

This thing works great!

Yuanzi spoke first, "I have basically finished reading these five books, and I have memorized all the knowledge points the teacher said. It's a great feeling." The excitement in the words can be heard.

Xiaolan also happily answered, "I'm really learning so fast, I feel like there are several of me who are learning at the same time." Only then did the two girls realize that one voice was missing.

Turn around and look together.

I saw Yan Sagawa on the side burying his head in the manuscript paper, writing down a large line of data with the pen in his hand, sometimes stuck and stopped, and kept turning the pen to think.

Looking at the manuscript papers filled with formulas and words next to it, one can see that during these 3 hours, Sagawa Yan also did not waste a bit.

Both Xiaolan and Yuanzi showed admiring eyes.

Yan Sagawa, who has published several papers and is known as a genius mathematician, is still working so hard. "That's to say, we don't understand what he's working hard for." Yuanzi suddenly pursed his mouth and complained angrily. Xiaolan laughed, "That's true." From mathematics to biology to information and then to physics.

No two women can understand it.

At this time, Yan Sagawa also noticed that the two girls had stopped studying.

So he temporarily stopped thinking and put down his pen.

He said with concern, "You two, go to my bedroom and take a rest, or go to the side to rest." He knew that taking the medicine for the first time, plus 3 hours of study time, it is easy to be extremely mentally exhausted.

"We'll just rest in your room for a while."

Xiaolan shook her head lightly, she and Yuanzi still wanted to get along with Sagawayan more.

Watch out for this period of time and prevent outsiders from taking advantage of it. This is the consensus between her and Yuanzi.

Sonoko also nodded in agreement. . … . . . . Ask for flowers. . . .

Sagawa Yan didn't feel that there was anything wrong, and stepped forward to support one of them.

Both Xiaolan and Yuanzi nestled themselves on Sagawa Yan.

Sagawa Yan led the two of them into the bedroom, carefully put them on the bed and covered them with blankets. "You guys have a good rest."

Xiaolan and Yuanzi were already very sleepy at this time, and let out a kitten-like hmm.

Then the eyelids couldn't help but close.

Sagawa Yan took a look at the cute sleeping faces of the two, and chuckled, "Sleep well."

"What happened to the banquet on the boat yesterday?"

Xiao Ai repeated Sa Chuan Yan's question, and looked at Sa Chuan Yan strangely, "Didn't you notice at all?" Sa Chuan Yan found Xiao Ai in the underground laboratory, and took the opportunity to ask his doubts. . 0 He nodded, "I didn't feel what happened at all."

Xiao Ai looked at Sagawa Yan with a strange look for a while, then suddenly smiled. "Then let me tell you."

She expressed all the worries of the women.

"So that's how it is," Sagawa Yan finally figured out all this.

Originally, I wanted to explain it to a few girls, but I suddenly realized that it didn't seem necessary.

Thinking about the active performance of a few women, it seems to be not bad.

"They will only be like this temporarily. After waiting for a while, they will find that there is no threat, and they will be fine after living as usual." Xiao Ai explained.

Sagawayan thought of something, approached Xiao Ai and said, "What about you, why don't you seem to be worried at all?" Xiao Ai would not say that she was also a little worried, but she didn't show it. "I just discovered your otaku essence."

Xiao Ai said lightly, "Obviously, as an onmyoji, you can have as many women as you want, but in the end, there are only a few of them, and you haven't met them before, and you are in scientific research all day long, so I don't think you will touch those. "No, I just feel that the time is still very long, and I want to walk slowly with you, so I am very patient," said Sagawa Yan, "However, it is too much for you to say that I don't touch it." He approached Xiao Ai lowered her head, her pupils were wide open, and she kissed her.

It took a long time to separate. "What about now?" Sagawa said with a smile.

Xiao Ai's eyes were full of shyness, but she said in her mouth, "You pervert, lo*ic*n."

The little feet in slippers kicked a few times, venting the shame in his heart. predict.

Chapter 189 The Summer Vacation Begins (Part 3, end of Volume 1)

That night, Xiaolan and Yuanzi slept deeply, and Sagawa Yan couldn't bear to wake them up, so he had to call himself to explain clearly.

"Yes, yes, yes, nothing will go wrong, please rest assured."

Sagawa Yan hung up the phone with sweat profusely.

He called Mori Kogoro.

I want to help Xiaolan say that I won't be going back tonight.

Then began the process of being preached by Mori Kogoro.

Uncle Mao Li was obviously worried that he would do something bad with his intentions.

From the yelling at the beginning, to the persuasive education, and several times to drive to pick up Xiaolan, finally, with Sagawa Yan's assurance and the good impression he left before, he finally agreed.

Think about Uncle Mao Li's last sentence, "Xiaoyan, you are still young, it's too early for the one that is bad for your health. Although we both agree, we must restrain ourselves."

Sagawa Yan nodded his head "Seven Nine Zero", the love of parents is still heavy.

Greeting Ayako is much easier.

In front of outsiders, she is the calm and calm female president Ayako, but she is very shy in front of Sagawa Yan, who hesitates and refuses.

As soon as Sagawa Gen said the matter, Ayako hurriedly agreed.

He shook his head and temporarily put aside these chores.

"Since there is no place to sleep, let's explode the paper."

Sagawa Yan stretched his waist, stretched his body, and came to the study.

There were manuscript papers scattered all over the table. After tidying them up a bit, he continued his scientific research.

After midnight, Sagawa Yan's spirit also diverged a little.

On the one hand, I was still thinking about the next step of the thesis, and my pen did not stop. On the other hand, my brain was diverging my thoughts and making random associations.

"Field theory, and many bodies, is it possible to appear in practice? Impossible. How about the verification of string theory? Does multi-dimensional space exist?"

Big and small physical knowledge points repeatedly collided in thinking.

Strings, superstrings, dark matter, nuclei, graphene, these physics knowledge that he had heard in his previous life or understood in this life kept appearing in his mind.

In the end, all dissipated, and only one word appeared, controllable nuclear fusion.

energy!

It is the key to restrict everything, others are too far away and impractical, but nuclear fusion is the closest and most useful thing.

"Thinking of it this way, the power of stars and nuclear fusion are the greatest practical applications of modern physics."

The clock hanging on the wall slowly came to 12 o'clock.

The door of the study was pushed open.

Xiao Ai came in carrying something.

Sagawa Yan noticed it this time, and hurried to pick it up. It turned out to be a cup of hot milk and some cookies. "My little Ai is so cute, she knows she loves her boyfriend, so she specially brought her a midnight snack." Sagawayan couldn't help but gibberish again.

Xiao Ai still remembered what happened in the laboratory just now, so she couldn't help kicking Sagawa Yan a few times. "lo*ic*n..."

"Hey, are you going to be in the study tonight?" After hesitating for a while, Xiao Ai asked Sagawa Yan.

"Maybe. If I can't hold on, I'll go to the sofa in the living room and sleep well." Sagawayan happened to be a little hungry, so he picked up a cookie and ate it.

"Actually, I have a question. Why do you only install tatami mats in the bedroom and the room on the second floor, but you can also install tatami mats in the living room or study room? Isn't this much more convenient?" Xiao Ai asked inexplicably. I've wanted to ask for a long time, in a house in Sakura Country, shouldn't the main rooms be covered with tatami mats for rest?

Sagawayan stopped eating the biscuits, even choked, took a sip of milk, and then spoke. "I didn't expect that."

After all, unlike the natives of Sakura Country, how could he know this. "Next time, I will definitely do it next time."

He gritted his teeth and said, sleeping on the sofa is not as good as sleeping on the tatami.

Xiao Ai looked at Sagawayan speechlessly, until he finished eating the biscuits and drinking milk, then said, "Then I'll go to bed first, and you should go to bed early too." After finishing speaking, she didn't care about Sagawayan's reaction, and left with the plate out. "Really, not honestly."

Sagawa Yan smiled lightly, feeling that his body regained energy after eating supper, and he cheered up again. "Okay, let's go all night."

He let go of his rhetoric, and got into the physical world again.

The window is deep and quiet, and the window is brightly lit.

And this light is one night.

It was already 9 o'clock in the morning when Sagawa Yan woke up again.

"Well, I'm still asleep."

He remembered that it was almost 6 o'clock when he couldn't hold on and fell asleep.

Standing up, a blanket slipped off her body.

Feeling warm, it seems that some girl covered him in the morning.

After briefly sorting out the results of last night, the outline of the thesis is roughly finished, and the things to be demonstrated are roughly out...

Then you just need to continue to complete it on the formal paper.

He walked out of the study and found two notes left on the table in the living room.

On the bottom one is Xiaolan's beautiful handwriting, "Yan, Yuanzi and I are going to class first, there is a hot breakfast for you in the kitchen, remember to eat it, girlfriend Xiaolan and Yuanzi will stay."

And there is another one on the top, which is Mingmei's handwriting, "Master Yan, Xiao Ai and I have also gone to class, and I have added some food for you, remember to finish eating, smiling face."

Xiao Mingmei seems to have increased the amount of breakfast on the basis of Xiaolan's breakfast, and Sagawa Yan has a bad feeling.

When he walked into the kitchen and saw a lot of food, he couldn't help smiling wryly, and I knew it.

Sandwiches, bacon, cornflakes, bread, natto, miso soup, saury, porridge.

Alas, eat it, don't ask, asking is the love of your girlfriend.

Sagawa Yan, who was full after eating, finally returned to his room.

"Replenish your sleep, or you will be really sleepy."

Smelling the fragrance left by the two women, he couldn't hold back and fell into a deep sleep.

In the next few days, Yan Sagawa continued to complete the thesis, while Xiaolan and Yuanzi were also preparing for their own exams.

On Saturday, he was obsessed with thesis, and for the first time, he took a leave of absence from the Yoshida family and canceled the tutoring for this week.

And the retribution came very quickly. On Zhou Tian, ​​Hongzi sent a crow to deliver the letter. Because of the exam, the first magic remedial class was also cancelled.

It was only then that Sagawa Yan remembered that Hongzi, and the girls like Kazuya were all 1.4 high school sophomores.

Damn Qingshan old thief.

After habitually throwing all the blame to Aoyama, Sagawa Yan had no choice but to continue to immerse himself in physics.

Soon, a paper related to quantum mechanics was officially completed.

Sagawa Yan carefully selected the publications for submission. The top two of nature and science must be out of the question, and the top ones that only accept drafts from big cows are also out of the game.

After thinking about it, I chose "Physics Letters" from Tulip Country, which has a good impact factor.
