I almost touched the moon

More than two hours later, Wen Song finally stood up and went downstairs to the bathroom. As he walked, he was still mumbling something like, "If substitute angular momentum of Neptune.. T?v is 9.966 x 10?1 kg m2/s, then G?v=..." (If you substitute angular momentum of Neptune.. T?v is 9.966 x 10?1 kg m2/s, then G?v=...")

When she came back, she was still talking to herself, muttering softly, and sat back in front of the computer to start calculating. However, after nearly an hour, she was still frowning and had not obtained a result.

When I wanted to smoke, I found the cigarette box was empty. I looked around the study but only found a few empty cigarette boxes.

She turned her head and looked at Cheng Che with a pleading look in her eyes.

Cheng Che noticed her movements to look for cigarettes, glanced at her, and said coldly: "I'm not going to buy cigarettes for you, stop smoking, how many have you smoked today, do you have a pack?"

"Hehe... please." Wen Song smiled and stuck out his tongue, pretending to be spoiled and said to him, "I'll smoke one more cigarette, just one. I can't write without smoking."

"Why are you so addicted to smoking?" Cheng Che frowned in dissatisfaction and immediately refused, "No, I don't want to serve you at the bedside in the future."

"Don't worry, it won't happen." Wen Song said immediately, "When that day comes, I will be euthanasia, and you won't have to serve me anymore."

"Don't talk nonsense!" Cheng Che immediately stepped forward and covered her mouth, shouting, "You promised me that you wouldn't talk about death so easily."

"I was just kidding." Wen Song knew his taboo, so he didn't say anything more. He put his arm around Cheng Che's waist and said, "I just smoked a little too much these two days because I was rushing to meet a deadline. I promise to smoke less in the future."

"I've never seen you smoke less." Cheng Che muttered unhappily and hugged her, but he smelled the strong smell of cigarettes on her hair and frowned unhappily.

Wen Song smiled, then suddenly raised his head, looked at him expectantly and asked, "A Che, how are you at math?"

"It's OK, but definitely not as good as you."

"I'm not good at math..." Wen Song smiled self-deprecatingly, "Among all my subjects, my math score is the lowest."

"Really?" Cheng Che was skeptical. "The worst score but he scored 1.7?"

When he helped Wen Song organize her bookcase, he looked at her undergraduate transcript. Although it was not high compared to the scores of other subjects that were no less than 1.4, this score was undoubtedly at the top.

"Relatively speaking." When talking about grades, Wen Song showed a confident and proud smile on his face, and asked Cheng Che, "So how are you in math?"

"It's OK." Cheng Che smiled and said, "General calculations are no problem."

"Then do you know how to calculate field equations? I'll give you the formula."

"What?" Cheng Che had only heard of Einstein's field equations during college, but had never understood them, let alone solved them.

"Sister, you think too highly of me... If you can't do it, how can I?" He muttered softly, his eyes a little evasive.

"How can you not know it?" Wen Song looked at him half-jokingly and said, "You are Einstein's junior, you must know it."

"I'm not from the Physics Department." Cheng Che didn't know whether to laugh or cry. "At most, I'm just an alumnus. Baby, I can't help you."

"I'm just kidding." Wen Song checked the time. It was already past one in the morning. He urged Cheng Che, "Go to bed. I'll try to find an exact solution."

"It's late." Cheng Che frowned and said, "You should go to bed soon, and we can figure it out tomorrow."

"It's okay." Wen Song smiled and shook his head, "I'm not sleepy. Okay, go to bed quickly, don't stay up late with me, you will become ugly."

Cheng Che had no choice but to kiss her forehead and said, "Then don't stay up too late, go to bed early, I'll wait for you."

After he left, Wen Song returned to the computer and started calculating. However, no matter whether he used the computer or calculated step by step by hand, he could not come up with an exact solution.

Although an exact solution to the field equation is usually not required in preliminary research reports, an approximate value is sufficient, but she insisted on getting an exact solution with an almost obsessive-compulsive obsession. After three hours of hard thinking without any results, she called her undergraduate classmate who was studying for a master's degree at MIT.

"Hallo Eirlys, Ich glaube nur du kannst mich retten." (I think only you can save me.)

Eirlys had just finished class and was delighted to receive Wen Song's call. They immediately discussed the solution and the possibility of obtaining an exact solution.

At around five in the morning, Cheng Che turned over as usual and tried to hug the person next to him, but he found nothing. He woke up and found that there was still no one beside him.

He walked out of the room and saw that the light was still on in the attic. He sighed softly, poured a cup of hot tea and went up to the attic. When he opened the door, he heard voices coming from inside. Wen Song was chatting with someone in a mixture of German and English, talking about some physics and mathematics terms that he vaguely understood.

Cheng Che didn't dare to disturb her, so he placed the jujube kernel and water chestnut tea on the desk, and wrote on the draft paper beside her, "I'm going to continue sleeping, sister, go to bed early."

Wen Song took a sip of the tea he brought, continued discussing with the person on the phone, and calculated on the iPad, and only made an "ok" gesture to Cheng Che.

However, until after six in the morning, after writing more than a dozen pages, Wen Song and Eirlys were both dizzy and had not yet come up with an exact solution.

Eirlys persuaded Wen Song, "Ilia, the value we obtained is very close to the exact solution. I think if you just want to use it to calculate the influence of the space-time curvature of Neptune's orbit on the formation of Kuiper Belt objects, this value is sufficient."

"I know." Wen Song also realized that Eirlys had been discussing with her for more than two hours, and it was not good to bother her any more, so she said to her, "Thank you, baby, you are so kind, you saved me. I will use this data, thank you so much, I love you."

"You should go to bed now." Eirlys also smiled and gently urged, "Good night, my dearest little Ilia."

After hanging up the phone, Wen Song also felt sleepy, but was afraid of disturbing Cheng Che if he went downstairs, so he turned up the heating in the study, lay on the sofa, and prepared to spend the night in the study.

What she didn't know was that Cheng Che didn't fall asleep, but was waiting for her, wanting to massage her shoulders and neck that were sore from sitting for a long time before she went to bed.

It was almost seven in the morning, but Wen Song still hadn't returned to the bedroom. Cheng Che thought she was still writing a research report, and while complaining, "How can you be healthy if you stay up all night and don't eat well?", he walked out of the bedroom, thinking that even if she scolded him, he would carry her down to sleep.

However, when he walked out of the bedroom, he found that the light in the attic was off. He felt a little strange, strode upstairs and opened the study door, only to see Wen Song lying on the sofa, covered with a cashmere coat.

"Song Song..." He lowered his footsteps and walked forward, only to see that Wen Song was sleeping very soundly. Perhaps because of staying up late, her breathing was a little rapid, and there were obvious dark circles under her eyes.

Looking at Wen Song's tired sleeping face, he sighed with some heartache, picked her up sideways, and carried her back to the bedroom gently. She must be very tired, so even though he held her and the sound of the stairs was a little loud when they went downstairs, she didn't wake up and was still sleeping soundly.

Cheng Che covered her with a blanket, turned off the light, and lay down beside her. He suddenly felt a little reproachful.

I could have finished the task ahead of time, but I had to put it off until the last minute, making myself so exhausted. I clearly said that I had no dreams, and I didn’t know why I was studying so hard. If I just wanted to get by, I would have just passed the exam. Why should I be so perfect?

At half past nine in the morning, the alarm clock rang on time. Wen Song opened his eyes reluctantly, only to find himself lying on the bed in the bedroom.

Seeing her wake up, Cheng Che immediately came over to massage her shoulders and neck, and asked with concern: "Why don't you take a day off today? You hardly slept last night."

"It's okay." Wen Song yawned and relaxed his stiff cervical spine. "My supervisor has to go to the ESA meeting tomorrow, so I will take a day off tomorrow. It's not a good idea to take a leave today."

"Then don't stay up late tonight." Cheng Che frowned and said worriedly, "If you stay up late like this every day, be careful of sudden death."

"Got it." Wen Song stretched and said with a smile, "Only the conclusion is left, and I can finish it tonight. Ah Che, don't worry about me, I'm used to it."

After hearing what she said, Cheng Che complained silently in his heart, "How can I not worry? She doesn't have any healthy living habits. How can someone not take her own body seriously?"
