When watching some news, Shang Yiyun was also thinking about some things in his heart, although his current ability is more outstanding, but he always believes in a sentence, there are people outside the world, there are heavens outside the sky, and in other places, there may be people who are more outstanding than his ability.

In the past, he had been doing experiments in the school's laboratory, and rarely went out to communicate with some young researchers of the same age, but now he has an opportunity, and that is tomorrow's youth science and technology seminar.

He believes that tomorrow's Youth Science and Technology Seminar will definitely give him something to gain.

Thinking of this, Shang Yiyun's heart was also full of expectations, but he also knew that this kind of thing should not be rushed, even if he was in a hurry, it would be useless, because this youth scientific seminar would not be held in advance because of his urgency.

At this time, he also calmed down, threw away the thoughts in his heart, and began to continue to pay attention to current affairs news, seeing the picture that appeared on the computer screen, Shang Yiyun was also a little awe-inspiring in his heart, because it was a picture of ruins after a war.

The picture that is being played now is somewhere in the Middle East, the Middle East is known as the most chaotic region in the world, and this kind of thing is commonplace, today you fight me, tomorrow I will fight you, war can happen at any time.

Seeing this situation, Shang Yiyun was also glad in his heart, he was born in a relatively peaceful country like Huaguo, so he didn't have to worry about the threat of war, and he could do what he liked with all his might.

As time passed, Shang Yiyun turned off the computer, lay on the lounge chair, and recalled the picture he had just seen, which was a little shocking.

Looking back on it now, it's still fresh in my memory.

However, he has no ability to stop this kind of thing now, even if he feels uncomfortable, there is no way.

While there was still some time before he rested, he was about to look for a few books on the bookshelf, when suddenly, he saw a book related to art and took it out of the shelf.

Looking at the book in front of him, Shang Yiyun's thoughts returned to the past, at this time he remembered his previous experience of studying art, and he also felt a little emotional, thinking about things related to painting that he hadn't been in contact with for a long time, he suddenly had an idea in his heart.

Now there is a set of painting tools in the dormitory, so he plans to paint a picture, which can be regarded as a kind of nostalgia for the past.

As soon as he said and did, he took out the painting tools from under the bed, first supported the easel, then put the drawing board on the easel and pasted the drawing paper, and finally put the paint on the ground, beat the water in the bucket, took out the paintbrush, and began to create.

Although he has not painted for a long time, his painting level has not declined, and the things he is going to paint this time belong to freehand painting, which can also be said to be abstract painting, and realistic painting are completely different painting styles.

Starting from the shape, step by step, it only took half an hour for a painting to finish from the beginning to the end.

After painting a painting, Shang Yiyun began to appreciate his works, because the level of fine arts has also reached the doctoral level, and the level of painting is still very high, so the first feeling of this painting is beautiful.

Looking at his work, he was quite satisfied, so he put the painting on the easel, prepared it to dry, framed it, and hung it on the wall of the dormitory as an ornament.

After putting away the paints, brushes and other tools under the bed, Shang Yiyun took out the clothes to dry from the outside, prepared to take a shower, and then began to rest.

Tomorrow's Youth Science and Technology Seminar will start at 8:00 a.m., so he plans to take a good rest tonight and recuperate.

After a simple hot shower, Shang Yiyun climbed onto the bed, ready to close his eyes and rest.

The night was as dark as ink, and the shining stars became a part of the entire starry sky with their faint light.

After dawn the next day, Shang Yiyun got up and dressed, and then, as usual, went to Huaguo Normal University, accompanied Chen Feiyun to run and exercise, and finally had breakfast and returned to Kyoto University.

He was not the only one who participated in the Youth Science and Technology Seminar, and there were other people at Kyoto University who were just as qualified as he was.

What he has to do now is to wait for the arrival of the meeting time, starting from the school at 7:30, it will take more than ten minutes to reach the destination, and now it is just 7:10, and there are still 20 minutes before the meeting time, so he is ready to wait in the dormitory for a while.

Ten minutes passed quickly, and Shang Yiyun had already packed up his things, walked out of the dormitory door, and went to the meeting place, that is, the school gate.

As long as he can get to the meeting place in ten minutes, that's fine.

Because Shang Yiyun's dormitory was not too far from the school gate, he was not in a hurry, so he walked slowly, and it took less than ten minutes to finally arrive at the school gate.

At this time, he saw several people standing there at the school gate, as if they were waiting for something.

Seeing this situation, Shang Yiyun came to the side of several people, began to eavesdrop on the conversations of several people, and after confirming the identities of several people, he joined the chat.

"Hello seniors, my name is Shang Yiyun, I am very happy to be able to participate in this youth science and technology seminar, and it is also my honor to meet you here. ”

Hearing Shang Yiyun's words, several other people were also surprised, because they had heard of the name Shang Yiyun before, and now that they saw me, they were naturally more curious.

"Senior Brother Shang Yiyun, hello, my name is Yang Siyun, are you the student who is called the demon in the legend? And although you are a freshman now, you have already made great achievements. ”

At this time, the only girl among the several people said.

Others were also curious about this question, so they all listened attentively.

Faced with this situation, Shang Yiyun did not choose to hide it, but nodded. Agree with the other person's statement.

Others received an affirmative answer, and they stopped dwelling on the topic and began to talk about other issues.

These people are all Ph.D. students at Kyoto University, and they are a small group of people who are relatively good, so they talked about professional issues as we chatted.

No one would treat Shang Yiyun as a freshman, but put him in the same position as them.

However, Shang Yiyun found that since he knew his identity, there was a person who looked at him differently from the others, because there was resentment in this person's gaze.

Shang Yiyun was also puzzled by this situation, because he didn't know this person at all, so he didn't understand where the other party's hostility came from.

Perhaps sensing Shang Yiyun's doubts, at this time, the girl named Yang Siyun came to him and spoke.

"Senior Brother Shang Yiyun, are you very confused now, why that person is hostile to you, do you want to know?"

Yang Siyun obviously intended to hang Shang Yi Yun's appetite, so he didn't tell him the answer directly.

For this situation, Shangyi Cloud is also helpless.

"Of course I want to know why, but if you hang my appetite now, just say something. ”

Yang Siyun was not satisfied with Shang Yiyun's answer, but she had no intention of continuing to hang Shang Yiyun's appetite, so she directly stated the reason.

After listening to it, he was also a little helpless in his heart, even if he didn't provoke others, but others would put some things on him.

The person who was hostile to him before was named Wang Huafeng, who was also a student majoring in materials science, and the other party had been researching repairable materials.

As a Ph.D. from Kyoto University, Wang Huafeng felt that his ability was very strong, but when he heard that Shang Yiyun had researched three repairable materials, his self-esteem in his heart was completely damaged, so he showed hostility towards him after meeting.

But for this kind of thing, he didn't take it to heart.

After all the people arrived, they set off to the location of the seminar, and it took less than 10 minutes to reach the final destination.

After entering the venue, Shang Yiyun had many young men, but the other party was older than him, and he was the youngest of all the people present.

According to the arrangement, I sat in my seat and began to wait for the official start of the Kyoto City Youth Science and Technology Seminar.

After waiting for a while, the time reached eight o'clock, and the host picked up the microphone to announce the official start of the 16th Kyoto City Youth Science and Technology Symposium.

At the beginning of the seminar, some leaders began to speak, and after some talk, they got to the main topic.

Faced with this situation, Shang Yiyun was also very helpless, but he also knew in his heart that these were necessary processes, and patience would pass.

"When the youth is prosperous, the country is prosperous, and when the youth is strong, the country is strong. The young generation has ideals, skills, and responsibilities, and the country has a future, and the nation has hope, so the vast number of young people must strengthen their ideals and beliefs, aim high, be down-to-earth, be brave to be the trendsetters of the times, and let their youthful dreams fly in the vivid practice of realizing the Chinese dream......"

As soon as one leader finished speaking, another leader began to speak.

"The living conditions and growth experience of contemporary young scientific and technological workers are completely different from those of the older generation of scientists, and today's conditions in all aspects are far better than those at that time, but the older generation of scientists in the difficult environment, still indifferent to fame and fortune, overcome difficulties, and break through a lot of "stuck neck" technology, which is admirable and admirable, I think this is also what we should learn all our lives, as a young scientific and technological worker, we should have the courage to do original innovative research, and really solve some of the "stuck necks" Key technologies, do research and not just make a fuss......"

......

After some leaders made speeches, the next time entered the core part of the seminar, which is also the part that Shangyi Cloud is looking forward to.

The first to speak was a young man wearing glasses and a suit, who seemed to be a more rigorous person in life.

What the young man said was related to celestial mechanics, and this seminar was different from the previous show.

There is no determination of the topic, but free play according to one's level of knowledge and ability.

"Celestial mechanics is a branch of astronomy that deals with the motion of celestial bodies and the role of gravitational attraction and is the application of physics, especially Newtonian mechanics, to the study of the mechanical motion and shape of celestial bodies. The object of study is the celestial bodies and star systems in the solar system with few members. It began with the development of Newton, Glarange and navigation, and was perfected with the maturity of theoretical research. ”

"Celestial mechanics can be divided into six categories: perturbation theory, numerical methods, qualitative theory, astrodynamics, celestial shape and rotation theory, many-body problems, etc. ”

"Celestial mechanics is also used to compile celestial ephemeris, and the remarkable achievement is the development of astrodynamics, the study and development of the orbits of various artificial satellites. ”

"Celestial mechanics is mainly based on mathematics, and the shape of celestial bodies is mainly based on the equilibrium shape and change laws of fluid or elastomer under the action of internal gravity and rotational centrifugal force. ”

"The gravitational attraction within and between celestial bodies is the main factor that determines the motion and shape of celestial bodies, and celestial mechanics is based on the law of gravitation. ”

"The main direction of my current research is astronomical dynamics..."

In ten minutes, the man first briefly explained the relevant knowledge of celestial mechanics, and finally said his research direction and some achievements.

When he was done, the man put down the microphone and looked around to see how the others were reacting.

For this situation, Shang Yiyun's performance is very calm, because the other party's achievements are already relatively good compared to ordinary people, but if compared with him, it will be worse.

After the man finished, the next person to give a speech was a woman.

"Thermodynamics is a discipline that studies the properties of thermal motion of matter and its laws from a macroscopic perspective, and belongs to the branch of physics, which and statistical physics constitute the macro and micro aspects of thermal theory respectively. ”

"Thermodynamics is mainly the study of the thermal properties of matter from the point of view of energy conversion, which suggests the macroscopic laws that energy follows when converting from one form to another, and summarizes the thermal theory obtained by the macroscopic phenomena of matter. ”

"Thermodynamics does not investigate the microstructure of matter composed of a large number of microscopic particles, but only cares about the thermal phenomena that the system manifests as a whole, and the basic laws that must be followed by its change and development, it is satisfied with describing and determining the state of the system with a few macroscopic state quantities that can be directly felt and observed, such as temperature, pressure, volume, concentration, etc., through a large number of observations and experiments of thermal phenomena in practice, it is found that there is a relationship between macroscopic state quantities, and their changes are mutually restrictive. ”

"In addition to the properties of matter, the constraints must also follow some thermal laws that are applicable to any matter, such as the zero law of thermodynamics, the first law of thermodynamics, the second law of thermodynamics, and the third law of thermodynamics. ”

"Thermodynamics is based on the above basic laws obtained from experimental observations, and the application of mathematical methods and logical deduction to derive the relationship between the various macroscopic properties of matter and the direction and limit of macroscopic physical processes, so it belongs to the phenomenological theory, and the conclusions drawn from it have a high degree of reliability and universality. ”

This woman's voice is very good, and she has a deep understanding of thermodynamics, and Shang Yiyun also recognizes what she can say.
