He learned a lot from this book, and the content of this book is about neutrino communication.

Neutrinos have many advantages, such as strong penetration, speed close to the speed of light, propagation in a straight line, no reflection, refraction and scattering, good secrecy, it can directly pass from the south pole of the Earth star to the north pole, the whole process almost does not lose any energy, it is precisely because of this that it is used as a communication tool, there are great advantages.

Neutrino communication technology has been successfully tested decades ago, but the propagation distance is only a dozen kilometers, and it cannot be applied in practice at all.

What he wants to do is to stand on the foundation of his predecessors, continue to study, and strive to apply this technology to practice.

It's getting late now, and if he doesn't go back now, the dormitory may be closed, and then he can only stay outside for the night, so Shang Yiyun said goodbye and prepared to return to Kyoto University.

Faced with this situation, Chen Feiyun could only nod in agreement.

Before leaving, Shang Yiyun handed over the books in his hand to the other party and asked the other party to find a time to return the books to the library.

After saying goodbye to Chen Feiyun, Shang Yiyun walked back to Kyoto University, the distance between the two schools was not far, and it didn't take long for him to return to the school.

There was class tomorrow, and after a simple shower, Shang Yiyun climbed into bed and prepared to rest.

However, his roommates were curious about where he had gone, so they teamed up to ask.

"Say, where did you go today?Did you go on a date with the young lady?" This was Shen Fengyu's voice, which sounded so hateful.

"Hmph, what about me, do you dare to say that you are not with your girlfriend today?" At this time, Shang Yiyun wanted to lead the topic to Shen Fengyu.

Men and women in love can't wait to be by each other's side every day, he and Chen Feiyun have experienced this stage, and they naturally know it in their hearts.

Sure enough, the topic was led to Shen Fengyu, after all, Yue Xiaolei and Tian Xiaoyue didn't know about Shang Yiyun and his girlfriend, but Shen Fengyu was different, after all, they were in a school, and they would naturally be together in their spare time.

Hearing Shang Yiyun's words, Shen Fengyu suddenly felt that something was wrong, but Yue Xiaolei and Tian Xiaoyue obviously didn't give him time to think.

"Hehe, Feng Yu, you will seriously explain where you went today? Yi Yun's girlfriend is at Huaguo Normal University, after all, they are two schools, even if something happens, we have no way of knowing, but you are different. ”

The trio who asked Shang Yiyun before immediately disbanded, and there was infighting.

"That's it, Fengyu, you can explain it well, I also want to know about today's events. ”

Shang Yiyun did not forget to fall into the well, as the punishment of the other party to be the first to come out.

"I'm with my girlfriend today, and it's nothing to say this kind of thing. ”

"Talk, I'm going to rest. At this time, Shang Yiyun was not ready to continue to talk about this topic with his roommates, and directly said what he wanted to do most at present.

It's 10:10 a.m., and he's ready to go to bed and digest what he's learned today, which will help him in the rest of his research.

A high-energy proton accelerator is used to accelerate protons to obtain a high-energy electron beam with hundreds of billions of electron volts. It is then used to bombard the target, creating unstable particles. These particles change constantly, eventually forming neutrinos and other particles, which are then passed through a thick steel plate to sieve out the charged particles to obtain an uncharged neutrino beam. When an object is scanned with a neutrino beam, these neutrinos emit blue light as they travel through water, which can be received by a photomagnification device to obtain information......

After thinking about these contents, Shang Yiyun found that today's harvest is quite large, especially the detailed description of the methods and principles of neutrino communication technology, which gave him a deeper understanding of neutrino communication.

After thinking about it, Shang Yiyun fell asleep.

The next morning, I got up early and washed up, and then went to the athletic field.

There were two classes this morning, and before he came out, he asked Shen Fengyu to help him bring the books to the classroom, and after the exercise, he was not ready to go back to the dormitory.

Calculating the time, his thesis has been submitted for more than half a month, and I believe that the results will come out soon, and whether he can be admitted by that time is up to fate.

However, he is quite confident in himself and feels that the chances of his thesis being accepted into the academic journal Science are very good.

After exercising, he simply solved the problem of breakfast, and he didn't think about the paper.

The morning course was a course on the history of Western philosophy, and he couldn't say whether he liked or disliked this course, in short. He also took a second major to get him interested.

The current level of knowledge in philosophy is close to the doctoral level, so for him, he has mastered all these freshman courses, and even if he does not attend the lectures now, he is sure to get a high score in the exam.

However, as a good student in the eyes of the teacher, it is better to do as little as possible about absenteeism.

In the classroom, Shang Yiyun's people were in the classroom, but their hearts flew outside.

I finally got through to the end of class, and I was about to go back to make up for sleep, but I was stopped by three roommates.

After hearing the reasons of the three of them, Shang Yiyun realized that the footsteps of New Year's Day were getting closer and closer, and they were going to perform a skit collectively in their bedroom, so they needed to rehearse.

Just take advantage of the time when there is no class, you can rehearse well, only in this way, when you perform on the day of the New Year's Day party, you will not panic, which will lead to a very poor performance effect.

Thinking of this, Shang Yiyun is also ready to practice a new flute score today, but the most important thing now is to rehearse the sketch first.

The four of them found some simple props and performed according to the printouts in their hands.

At the beginning, Shang Yiyun memorized the lines after reading them once, but his other three roommates did not have such a good memory, so they could only read them with the printout in their hands.

Of course, as the number of rehearsals increased, everyone's memory of the lines also increased, and although they were a little unskilled, they were able to perform off-script in the end.

To this extent. The four of them were already very satisfied, so they disbanded and went about their own business.

After Shang Yiyun returned to the dormitory, he took out the printout of his bamboo flute and flute sheet music and began to play.

Although this is the first time he has played this song, after he played it, it was still very beautiful.

After a few more exercises, it was twelve o'clock, and he usually chose to eat at this time, and today was no exception.

New Year's Day is coming, which means that the time for the holiday is also approaching, this year's winter vacation, that is, the Chinese New Year's Eve, he will stay at home for a while, after the New Year, he will return to Kyoto.
