Dear Miles,

The battlefield is indeed a battlefield, and as it was said in the last email, dead people are common. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoThis time, I finally saw the dead.

Seeing the dead in person is completely different from what you see in those movies and TV shows. It's a feeling to watch someone who was alive a second ago suddenly die motionless......

I can't describe it. I really can't describe it. At that time, I only felt that my legs were weak and I sat on the ground, and then I could only tremble and watch the assailant slowly approach with the gun whose barrel might still be hot. I don't know what they're trying to do. I tried to get up and run away, but my legs were completely weak, and the eyes of the corpse lying there were fixed on me, as if some kind of curse had been cast on me. Everything became terrible, and it seemed that only the hideous-looking Chinese in front of him existed objectively. As a physicist, it may seem funny to use the term "objective existence" in this context, but I did feel that way at the time.

After this state lasted for a while, I heard the voice of another Chinese not far away. A familiar voice -- it was the Chinese's political commissar. When I heard this, I suddenly realized that my body was no longer shaking so much, maybe I should be similar to the person who suddenly grabbed a straw and fell into the water. I almost cried when I heard the soldier tell him to put down his gun and not hurt me, tears rolling in my eyes, thinking that I was finally saved.

Then, again, I heard gunshots.

Before this, I could never have imagined that a Chinese soldier would shoot at their commissar. Although he didn't turn his head, I guess the commissar must have a surprised expression on his face. I was already a little unconscious, and I even sat on the ground and gloated a little to myself: Look, your usual oppression of these soldiers has finally met their grievances, right?

What happened next was even more than I expected. The soldier, a professionally trained soldier, didn't hit! It wasn't until he fell in front of me with a trail of blood on his chest that I saw that the expression on his face was a ...... Twisted fear.

I don't understand what caused him to have this fear. Is it because they are facing a political commissar who has been oppressing them? I thought the same way at first. However, when I saw the political commissar slowly kneeling down in front of the corpse, tears falling to the ground, I suddenly felt that the "political commissar" I imagined might not exist at all. Would a man who is on the battlefield and can force his fellow citizens into battle with a pistol do such a thing as the man in front of me?

Ah, I don't seem to have said anything about what happened to me until now. On the way to the hotel, I thought I might not be able to find any more useful clues in the half-collapsed room, so I wanted to look for the route I had taken, and I actually ran into a Chinese who was facing a local woman...... I really don't want to say that, you know.

When I saw the commissar kneeling on the ground, I still tried to stand up, but my legs still couldn't get up. After some time, more Chinese came. After learning what had happened, they were silent for a long time around the commissar and the corpse. I was a little tired, and the impact of what had happened that day was too great. I have witnessed the loss of two lives. I couldn't sleep after being taken back to my apartment by the commissar, and although I felt very tired, I couldn't sleep at all. As soon as I close my eyes, I see the two corpses. I couldn't read some books at all, and I didn't seem to pack them up in the end.

I didn't sleep all night. When I noticed what seemed to be someone entering the room, I saw a man in a military uniform standing at the head of my bed. Of course, I was startled, but when I saw the other person's face, I suddenly felt a sense of peace of mind. It was the Chinese political commissar again, and this time his face was full of concern, as if he was worried about me so that he let him come and see me, and there were several cans on the table in the room that he had never seen before. I wanted to say something, but I found I couldn't say anything. He seemed to sigh at my performance, then took a can from the table, opened it, and spooned it to my mouth. I hesitated, but ate it anyway. The food in this canned food is completely different from the hard-to-swallow food of the previous days, it is very sweet, sweet to ...... It makes you want to cry.

I'm starting to miss Japan. Missing America. I miss the wonderful MIT. Missed the days when we walked by the Charles River. I don't know how long it took, but I seemed to have eaten the can, and the commissar sat on the other side of the bed, keeping a proper distance from me. I don't know why, but I immediately asked, "Aren't you going to say something?"

Then he spoke. I thought he would say something comforting or do some counseling or something, but he didn't mention it at all, but apologized for the wrong Edison quote and indiscriminate kicking me out of the barracks the other day, and asked me what Edison's words were. I was stunned for two seconds before I realized what he was saying. What a strange guy.

Then, the conversation began to shift towards physics. I talked to him about a lot of things, all very basic, such as Maxwell's equations, Lagrange second equations, Lorentz and Galileo transforms, and some famous thought experiments, such as Newton's bucket experiment, Einstein's turntable and his twins, and so on. He seems to be very interested in this aspect of things, and I don't know if it is fake. But it must be admitted...... Had a great chat. I can now understand the mood of my mentor, and it is very rewarding to watch others slowly figure something out under their own teaching. You say, how about I write a popular science article when I go back? Didn't Einstein also write "A Brief Introduction to the Special and General Theory of Relativity"?

By the time he left, I was in a much better mood. I still can't forget the shock of those two bodies, but I think I've been able to set out on my own to find the paper. When I saw him leave, I actually felt a little lost in my heart. He is a good person, he should be regarded as my benefactor, I used to quarrel with him a few times because of the loss of his thesis and prejudice against the political commissars in the Chinese army, and in retrospect, it was really a little undeserved. Perhaps we will never have a conversation like this again except on business.

As a result, the next day, I felt that I was really a fool when I lost myself yesterday. Before I could get up, I heard a knock on the door. Hurriedly put on his clothes and opened the door, and it was the political commissar standing outside, and the fact that he came to me made me angry and laughed and didn't know what to say.

He said, "I'll help you find your papers." ”

What do you think I should say?

After hesitating for a while, I agreed, firstly because a person's hope of finding a paper was too small, and secondly, because I felt that he should still be trustworthy. If I wanted to do something, it would have been easier when I was depressed, but I was also curious about the reason why he wanted to help me, so I asked him, and guess what he said? He told me with a serious face that he should be in charge of the soldier's ideological work, and that he should do something to make amends to the victim when something like that happened!

After hearing this, my curiosity was completely piqued. I'm sure you'll have this kind of curiosity, right? According to what the media says, shouldn't a person who holds an official position like a political commissar be the image of an autocratic tyrant, but it turns out that this is not the case at all! How can this not make people curious?

However, finding a dissertation is still the top priority. I went with him to the hotel where I had stayed, and it was still raining lightly outside—according to him, it had already begun to fall, but because I kept pulling the curtains and not noticing, it was no wonder that it felt dark in the room—so I took the folding umbrella you gave me. The hotel has been completely surrounded by them, and it looks like it is going to be demolished and rebuilt, after all, part of it has been blown up and completely dilapidated. He spoke to a guy who looked like a person in charge, and then told me that we had a day in the hotel looking for papers. Although it was said that it was one day, it was not easy for only two people to find a manuscript in the hotel, and he and I searched through the boxes and cabinets for an afternoon, plus this morning, but finally failed to find the paper, and could only watch the hotel be demolished. Alas, it seems that he can't find the paper, so just look for it nearby, and don't cause him too much trouble.

I was just about to look at the map and remember the places I had been when the rain suddenly fell heavily. Because I felt that I shouldn't have to carry a folding umbrella in the light rain before, I didn't take it out today, and my clothes were all wet. I should have read the weather forecast before I came out, but the weather forecast is not very accurate. When I came out of the hotel, I only brought those precious books and materials, and I didn't take out a change of clothes at all. When I was writing an email, I had to take off my clothes and wrap myself in the quilt, so I had to wear wet clothes tomorrow. I hope my clothes can be dried soon.

By the way, we had an interesting conversation with the commissar while looking for papers, when he asked me what Hawking's evaporation was. I know you're going to be weird when you see this, because there's only one Hawking radiation (Hawking_radiation) in physics. In fact, as far as I know, because black holes are able to emit Hawking radiation and evapotranspire, some Chinese who do not have much physical contact can easily record Hawking radiation as Hawking evaporation - in Chinese, "evaporation" is "zhengfa", which is only one word different from "evapotranspiration". At that time, I joked that Hawking's evaporation is the famous physicist Stephen William Hawking's transformation from a solid to a gas at high temperatures, and it was funny to watch his confused expression.

It's not early, I went to bed first, hoping that the clothes will dry sooner. In addition, why did it take you so many times to reply to emails? In the future, you should develop the habit of checking your mailbox regularly every day, you know? In case something important sent to you is missing, don't say that I didn't remind you, then it is purely your own doing.

Your best friend,

Yumemi Okazaki.
