I almost touched the moon

On Wednesday evening, Wen Song was sitting on the rooftop terrace with Cece and Cheng Che in her arms, watching the sunset. The early summer breeze blew her long hair, and the pink sunset reflected on her face, making her look particularly peaceful.

"I don't have anything to do on Friday. Let's go to Fussen after class tomorrow." Wen Song turned his head and looked at Cheng Che and said, "Cece has never been to Fussen. I want to take it there."

"Okay." Cheng Che agreed immediately, "But I want to go back to Munich on Sunday. That day is Axuan's birthday."

"It's his birthday..." Wen Song nodded and said with a smile, "Why don't we invite him to go to Fussen together? I haven't prepared a gift for him. He's a Gemini, so it's quite suitable."

"He's not allowed to go." Cheng Che immediately hugged Wen Song and said, "It's just our world for the two of us, why would he be a light bulb and get in the way?"

Wen Song also smiled and immediately nodded and said "Okay".

However, at this moment, the phone screen lit up, and it was an email from Professor Andrew.

After Wen Song clicked on it and took a look, he immediately sighed and said helplessly, "I may not be able to go. Professor Andrew invited me to attend the defense on Friday and sent me the paper, asking me to help him take a look at it."

She sighed again, fell on Cheng Che's lap and said, "It's so annoying. I don't want to go."

"Go ahead." Cheng Che bent down and kissed her. "We can wait until the defense is over before going to Fussen. Or I won't celebrate A Xuan's birthday. I'll give him some money and let him celebrate on his own. I think he'll be more comfortable."

Wen Song sighed again and said, "I went to read the paper. I was upset."

At 11 o'clock on Friday morning, Wen Song sat on the judges' seat in the first row of the classroom on time. Looking at the students who were nervously preparing on the podium, she suddenly recalled some past memories.

At that time, she was standing in that position, waiting for the "judgment" of the professors below the stage. However, thinking back carefully, she did not seem to be nervous at that time, but rather a little expectant and excited.

As time passed, she sat in this position with a relieved smile. Everything was going as she expected, and after a brief deviation, it returned to its normal track.

Several international students who came to watch the show were whispering in Chinese. Their voices were not loud, but they just happened to reach Wen Song's ears.

"Why is Iseylia here too? Brother Yang isn't even her student."

"Senior, you're done." The voice was Cheng Xuan. "I heard that Iseylia's defense questions were very tricky. They didn't seem difficult at first glance, but it was very difficult to answer them to her satisfaction."

When Wen Song heard this, he coughed twice, turned around to look at Cheng Xuan, and smiled with his face but not his eyes.

The foreign students next to Cheng Xuan immediately started to make a noise, "You're done. She heard you saying bad things about your sister-in-law."

Soon, the defense began. Professor Andrew introduced the process and rules and said, "According to the regulations, I invited Professor Ferrero, the dean of our department. Also, because Yuchuan's paper cited a lot of Chinese literature, and I couldn't find the exact literature based on the translation in your footnotes, and even if I found it, it would be difficult to understand the original text, so I invited Professor Iseylia to participate in today's review.

We will give you three scores based on your defense today and the content of your thesis, and the average will be your final grade. Professor Ferrero and Professor Iseylia, do you have anything else to add? "

Professor Ferrero began by saying, "Hello, Mr. Yang. I believe you are familiar with me. Today's defense is just a summary of your graduation thesis and master's studies, so don't be nervous. I believe you will pass. I wish you good luck. Professor Iseylia also graduated from LMU with a master's degree and has also experienced this stage, so she will provide you with a lot of help. You will definitely be happy to meet her."

Wen Song listened to her, smiled and said, "Yes, hello Yuchuan. But to be honest, I don't think you are very happy. Because when I walked into the classroom just now, you obviously showed a very frightened expression. Don't worry, I am very kind.

But you may have to be careful with Professor Ferrero, because when I was defending my thesis, she really asked me a lot of very tricky and complicated questions. But please rest assured that I will do my best to help you. "

After the defense began, Wen Song began to frown slightly. The paper was obviously well-written, but when Yang Yuchuan was presenting it, he almost just looked at the PPT and read the sentences on it. The content seemed to have copied the abstract and conclusion of the paper, and did not get to the essence.

When the question period began, Professor Andrew asked Wen Song first: "Just now Yuchuan mentioned that the basis of his paper came from a research and analysis report on the composition of the soil on the back of the moon by Chinese scientific researchers and the China Space Administration. But because I haven't read the original text, I am worried that there will be differences between the translation and the original text, so please ask Professor Iseylia first."

"Okay, thank you Professor Andrew." Wen Song said immediately, "First of all, Yuchuan, I am very interested in your paper. In your paper, you analyzed the impact of solar wind on the formation of lunar soil, and compared the differences between the lunar soil on the front and back sides of the moon due to the difference in the effect of solar wind.

You referred to a paper written by Dr. Xia Ninghe from the Chinese Academy of Sciences and quoted her conclusions. So I would like to ask you what specific differences do you think exist between the physical properties of the lunar soil on the far side and the lunar soil on the near side? Can you give one or two representative points? And what impact do you think these differences have on our study of the origin of the moon?

Yang Yuchuan immediately listed several differences, but when it came to the specific analysis, he fell silent. After a long while, he said, "I think this can well prove the giant impact theory of the origin of the moon."

When Wen Song heard this answer, he immediately frowned and said to him, "This question is explained and analyzed in great detail in the sixth paragraph of the third chapter of Xia Ninghe's doctoral thesis, and your thesis footnotes also stated that you referenced this chapter in her thesis. Did you really read the reference carefully?"

Yang Yuchuan immediately lowered his head and said "sorry", his expression becoming more complicated and nervous.

Wen Song smiled and said, "Don't be nervous, it's okay. The second question is, in your paper, you mentioned that during the formation of the early high-energy collision on the moon, the transfer and distribution of angular momentum directly affected the composition and structure of the lunar soil. So it is obvious that the angular momentum value of the Earth-Moon system that scientists once derived based only on the composition of the soil on the front side of the moon is not completely accurate.

So based on your understanding and research, what aspects can we improve when we study the angular momentum of the Earth-Moon system? "

Wen Song clearly felt that Professor Ferrero was already somewhat dissatisfied with the presentation and the failure to answer the first question, so he lowered the difficulty of the second question. He said in his heart, I can only help you so much.

However, although Yang Yuchuan answered a lot, he still didn't really get to the point. Wen Song frowned and said, "In your paper, you wrote that you used numerical simulation to study the changes in the angular momentum of the Earth-Moon system, so have you tried to calculate a more accurate angular momentum value? This shouldn't be difficult. Because your conclusion also mentioned the difference in angular momentum, what is the range of this difference?"

However, Yang Yuchuan still did not answer, but only gave her a very general range of values. Wen Song nodded and said with a smile: "My questions are over. Do Professor Andrew and Professor Ferrero have anything else to ask?"

After saying that, she silently wrote a 4.6 on the score sheet.

Yang Yuchuan's answers to Professor Andrew and Professor Ferrero's questions were still unsatisfactory. Finally, Professor Ferrero said with a little regret: "Mr. Yang, I think you don't know enough about your research content and graduation thesis. Maybe you need another month to do some more in-depth study to make up for your shortcomings."

Wen Song also suggested: "Dr. Xia Ninghe is my good friend, so if you have any questions when reading her paper, you can always ask me. Good luck."

When the defense was over, Wen Song, Professor Ferrero and Professor Andrew went outside the classroom to discuss and decide the grades.

In the classroom, Cheng Xuan curled his lips and said to the boy next to him with some fear: "Too cruel, my sister-in-law is really too cruel, I will never ask her to be my advisor."

He looked at Yang Yuchuan with some sympathy and said, "Senior, are you okay? It's okay, it's only for a month. Iseylia probably won't come next time. She's on vacation next month."

Yang Yuchuan was not very sad. He sighed and said, "It's my fault. She has been trying hard to save me. I thought Andrew would not ask any questions when he couldn't understand the Chinese literature. But who knew he would invite Iseylia. The moment I saw Iseylia, I knew I was doomed."

He added, "But then again, it's not bad to have Iseylia as a supervisor. One of my classmates has Iseylia as her supervisor. She often treats her students to meals and buys them gifts. She also brings them along when there are conferences or seminars. They travel in business class at best and stay in five-star hotels. I wanted to find her, but unfortunately her quota was full. Alas, I couldn't get her."

"That's right." A girl also agreed, "I heard from her doctoral sister that Iseylia took them to Milan for a meeting before. They stayed at the Four Seasons Hotel. Each person had a luxurious room with a view, and they all ate Michelin food. It was so cool to travel at public expense."

Another boy also agreed: "The government-funded travel is secondary. The key is that she is really patient with the students she supervises, and will teach them how to publish. And as long as you assist her in her research projects and papers, she will add your name as a collaborator when the paper is published. Not to mention letters of recommendation, if you want to pursue a doctorate, following iseylia can at least guarantee a doctorate at this school."

The girl sighed and shook her head again, saying, "But she only has a few master's students, maybe three or four a year. She said that she has low energy and can't handle too many people. By the way, Cheng Xuan, you should also ask Iseylia for guidance."

Cheng Xuan was so frightened after hearing her words that he immediately shook his head frantically, "I won't look for her. Am I sick? I want her to guide me. I don't want to live anymore."

"That's right." The boy next to Cheng Xuan smiled and said, "Young Master, you don't need it. You have your own money. But, friends, Iseylia's husband is Cheng Che. Ge Yi, didn't you tell A Xuan before that her brother is very handsome and you admire him very much? Then you should work hard. If you can let Iseylia be your supervisor, you can see your master more often."

"Yes!" The girl named Ge Yi said immediately, "Then I will study hard from today, hoping that Iseylia will accept me. Cheng Xuan, please help me, can you help me ask Iseylia and Master for mercy?"

Cheng Xuan laughed dryly a few times and said, "I'll try my best." He couldn't help but mutter in his heart, what's so good about Iseylia and Cheng Che, what's so good about them, what's so good about them, especially Wen Song, being her student is the biggest pain Cheng Xuan has ever suffered in his 22 years of life.
