What Zhang Han discovered did make them feel like they were living in a desperate situation.
But science is not useful immediately after discovering a problem, and it requires repeated experiments and changes.
They failed again and again, and overthrew again and again.
But because they rarely work together in such a concentrated way, the progress is very fast.
Even if it fails, it can quickly overturn the previous one and make new arrangements.
Senior Sister Zhang Han will go abroad for a period of time during the winter vacation. This retreat can be said to be the last time for this project in the near future.
Xuejiao is in the Department of Mathematics, and her physics knowledge has been quite good this year, but her focus is mathematics, and her physical strength is difficult to compare with several other big names.
She is more of modeling and derivation, and the main direction is to control others.
Xuejiao didn't feel any discomfort at all. It was not her field of expertise, so why should it be compared.
What she is good at is mathematics, and the most important thing for her in this team is to exert her mathematical strength, and she does not need to worry about physics.
People need to know when to keep moving forward and when to take a step back.
It's not like they didn't go home after their retreat. On the first day, Xuejiao came home at one o'clock in the morning. She went to bed as soon as she washed and washed, and rushed over early the next day to continue to help.
Zhang Han and the others too, even later than Xuejiao.
Sometimes I just wrap myself up in the office next door and sleep, then wake up and continue, taking every moment.
Under such high-intensity work, Xuejiao didn't even mention that she had a date with Lin Zhihua, but she didn't send another message.
It's not that Lin Zhihua didn't think about looking for her, but he knew that this was Xuejiao's busiest time.
If her appearance disturbs her, she will not be angry, but she will never be happy to see her.
Lin Zhihua reached out and touched the photo on the table. There are thoughts in his eyes.
"It's been two days, little girl, you must make up for me when you're too busy!"
Lin Zhihua has already figured it out clearly, then let her not arrange too many other things during this winter vacation, she must spend the New Year with herself!
By the fifth day, their simulation had a new breakthrough, and the dawn appeared.
Xuejiao is no longer home, and the phone is turned off when the battery is low, and no one cares.
The rice was sent to the laboratory by Zhang Han's deputy, and the large laboratory next door was also occupied by them. At this time, it was the final exam, and there were not many students who wanted to use the laboratory. Even if there were, they were transferred to other laboratories by Professor Jin.
This day was the last class of a professional class, and the teacher called the name.
When he clicked on Gu Xuejiao, no one answered, his face darkened, and he wrote it down in the booklet.
"When you go back, tell Gu Xuejiao to come find me in my office tomorrow!"
Mai Jiajia immediately showed a worried expression, but all the teachers knew Gu Xuejiao, so they couldn't help her answer.
After class, she called Xuejiao several times, but she didn't get through.
After thinking for a while, Mai Jiajia walked to the physics laboratory with two cups of hot drinks.
The small laboratory that Chu Sheng borrowed was where Xuejiao and the others used to stay in the past year, and she had been there too.
When they arrived at the laboratory, Mai Jiajia didn't dare to go in with something.
The door of the small laboratory where I used to stay was closed, but the door of the large laboratory next to it was open.
An unshaven young boy was sleeping, and a senior brother and a senior sister were eating.
She stood hesitantly for a while, the small door opened, and a man with a haggard face, also unshaven, but with glowing eyes came out. He passed by her as if he didn't see her, and entered the big laboratory directly.
Mai Jiajia: "… "
Although she didn't come many times, she and Chu Sheng had met many times. They met on the road before, and they would say hello anyway.
This time she was standing here, Chu Sheng passed by her but didn't seem to see her...
"Working." Chu Sheng's voice was a little hoarse.
As soon as he finished speaking, the graduate student brother and sister who came to help from the Department of Physics took a bite of rice, took the computer while eating, and took the things that Chu Sheng handed over.
They were all so serious that Mai Jiajia still didn't dare to speak.
She waited for a while, Chu Sheng returned to the laboratory, and Xue Jiao finally came out.
When I saw Xuejiao, Mai Jiajia really wanted to ask what happened to your laboratory
The man's beard is unshaven, and the woman's face is haggard, and her hair is not combed.
“Zhijiao…”
"Huh? Jiajia?" Xuejiao was almost walking past her, and she suddenly came back to her senses when she heard the familiar voice.
Mai Jiajia: "… "
She was a little helpless: "You almost made me think that I learned to be invisible, so that I couldn't see me."
Xuejiao scratched her head, her voice a little anxious: "That Jiajia, we have been very busy recently, what's the matter with you?"
"It's okay, I've called the name today. Teacher Zhen asked you to find him tomorrow." Mai Jiajia said and handed the hot drink to Xue Jiao.
Xuejiao took it and replied, "Oh, okay."
Mai Jiajia: "..." As soon as I heard it, I knew I wouldn't go.
"Then I'll go and tell him tomorrow for you. If you can't let go, it's better than not going."
"Okay." Xue Jiao hugged her gratefully.
"Then go get busy and pay attention to your body. I haven't seen you for a few days, why are you so thin?" Mai Jiajia was a little worried.
Xuejiao smiled back at her: "It's okay, I'll find you when I'm done."
Said to leave.
Mai Jiajia held her back: "Wait, don't forget that there will be an exam in a few days, you must not miss the exam, and you should review it..."
"Well, don't worry, we have reported the exam time to Senior Sister Hu, and she will notify us when the time comes."
Mai Jiajia: "..." I really don't plan to review...
She looked weak: "Okay, go get busy."
"Goodbye Jiajia, I'll find you when I'm busy!" Xue Jiao said, and left in a hurry.
Mai Jiajia looked at her back helplessly, and then looked at the other people who were engrossed.
It's all a bunch of research lunatics!
But what a cute lunatic.
…
On the eighth day, there was actually no success.
But the sense of urgency that victory was in sight prevented them from leaving the customs as scheduled.
In the afternoon, Xuejiao took the exam and came back to continue to help.
Zhang Han's original flight ticket was also cancelled and postponed for a week.
It just so happens that this week is exam week, they have to take exams from time to time, and then continue to come back to work, some delays, but there is no way.
On the tenth day, Professor Jin came more frequently and didn't bother them much. He just watched and nodded from time to time.
Yang Zhan left first, and his exams were concentrated in these two days, unlike Xuejiao and the others who came back easily after finishing the exams.
On the thirteenth day, Yang Zhan returned.
On this day, they have to build a new model, and the original program cannot support the model they want.
I asked Professor Jin for help and contacted Professor Tang from the Department of Computer Science. He brought Cheng Mingze over to help modify the software.
That night, they run the model all night.
At eight o'clock the next morning, Zhang Han, Yang Zhan, Chu Sheng, Zheng Jiakun, and Xue Jiao stretched their heads out in front of the computer, staring at the two computers.
Ten past eight.
The simulation on the computer is all loaded, and a small car with a small mark of 5KG floats...
"This is... successful?"
"Little Junior Sister! How much did you calculate before?" Chu Sheng grabbed Xue Jiao, he knew the data, but at this moment he had doubts.
Xuejiao's heart skipped a beat, took a deep breath, and said, "5.0178KG, the highest value available."
"Ah..." Chu Sheng threw up all the documents in his hand and danced in the sky.
Yang Zhan reached out and hugged Zhang Han, his voice excited: "Success! Success!"
Zhang Han was also very excited, his face was slightly red, but he subconsciously patted Yang Zhan: "Let go of me!"
Xue Jiao looked at the excited appearance of several people, and her heart was slightly warm. She knew that her current expression was the same as theirs.
It's been a year, and this project has been done for a year.
Chu Sheng's eyes were red: "Thank you, thank you very much."
His dream of speeding from childhood to adulthood has not been realized yet, but they have paved the first step.
Science is like this, there is a first step, a second step, and then there will be countless interested people who will continue to advance.
This is the progress of science and the progress of mankind.
They can only do 5KG now, and it may be more difficult in the future, but if there is a first step, there will definitely be a second step.
Chu Sheng also sincerely thanked these persistent friends. Xue Jiao and Zheng Jiakun were from the Department of Mathematics and spent a whole year in physics.
Zhang Han and Yang Zhan are even more elites in the scientific world. Their year is a very valuable year, but they have been spending with him on this project with a high failure rate.
Fortunately, they finally succeeded, otherwise the heavy burden would continue to be on him.
Zheng Jiakun stretched out his hand and patted Chu Sheng with a smile on his face: "This is a project that we are interested in, thank you? I should thank you for such an interesting project."
Xuejiao followed them and laughed, persisting for a year and finally succeeding. Half a month ago, they were still in despair, and they reap the joy today.
Science doesn't pay for it, and they are the lucky ones.
While they were ecstatic, Zhang Han's deputy looked at the time and suddenly said, "Little Junior Sister, you have an exam at nine o'clock, the last one..."
"Ah?" Xue Jiao was taken aback for a moment, then dropped everything and rushed directly to the examination room with a pen.
"Hey... Little Junior Sister... You haven't changed your clothes..." Before she could finish her words, Xue Jiao had disappeared.
Coincidentally, this happened to be for Xuejiao to go to the office to find him, the teacher Zhen's exam she didn't go to...
The other party was entering the door with the test paper and handing it to the invigilator. Seeing her hurriedly running over, her face darkened.
Teacher Zhen said in a calm voice, "Gu Xuejiao! You don't have your usual grades! Our usual grades in this class are 30%."
Xuejiao blushed and replied awkwardly: "I'm sorry Teacher Zhen..."
The other party put his hands behind his back, and continued in a calm voice: "You are in a sophomore year and you are eager to do a project, so that you can't even take classes. If you don't lay the foundation, you will be a castle in the air. Without the foundation, you can't do a good project! No matter how good the project is , as long as you fail the subject, you still don't have the qualification to be guaranteed research!"
After Teacher Zhen finished speaking, she went directly into the classroom, and Xue Jiao quickly followed up embarrassedly.
She didn't refute Teacher Zhen, because different people have different thinking, class is very important, Xue Jiao knows.
So unless there are special circumstances, she will go to every class.
But this time, she weighed the value of that class and project and decided to do the project anyway.
The last period was almost all model-related. When she left, Zheng Jiakun alone would not be able to keep up with Zhang Han, Yang Zhan, and Chu Sheng. It was a waste of everyone's time.
So at that time, she felt that the project was more important.
And this class...
Xuejiao had focused on studying when he proved Fermat before, and he had already listened to every class before this semester, and he has mastered it all.
Not bad for that class, but...
Xuejiao looked at the paper helplessly, it seemed that at least ninety years would be required to ensure that she would not fail the exam...
The question is not difficult for Xuejiao, and she finished writing and handing in the paper soon.
She quickly ran back to the lab and discussed with them the writing of the paper afterward.
"I suggest that everyone go back to rest now. Senior Sister Zhang Han has to catch a flight at night. I've been so tired recently. Everyone should go back and sleep well. The paper is easy to handle. Then just discuss it in the group directly." Yang Zhan said seriously.
Chu Sheng nodded: "Okay, I will type out a copy of everything, and everyone will bring a copy. It happens that it is also the winter vacation. Let's discuss and write the paper in the group."
The others nodded in agreement.
So at noon, Xuejiao went out with her bag on her back.
She had said in the family group that she was over, and Lin Zhihua said almost immediately that he had come to pick her up.
Xuejiao was a little embarrassed, but after seven days, it turned out to be half a month.
Boyfriend and girlfriend fell in love, she let him dry for half a month.
The familiar car came soon, and Xuejiao smiled in a pleasing smile: "Zhihua..."
Lin Zhihua was expressionless, opened the trunk, and took out an electronic scale...
"Stand up."
Xuejiao: "…"
She twitched, and finally stood up rather embarrassed.
42kg.
Xuejiao: "..." I lost eight pounds.
Sure enough, when he looked up at Lin Zhihua, the other party stared at the electronic scale with a terrifyingly black face.
