Xiao Xiao naturally quickly agreed.

Professor Wang took Xiao Xiao through the library and walked outside the school gate.

Xiao Xiao thought that the laboratory was on campus. Now when he saw Professor Wang walking off campus, he guessed that Beijing University had chosen another place to build a laboratory base?

At the school gate, two teachers and a student were already waiting.

Both teachers are from the Department of Physics and have also taught Xiao Xiao. Xiao knows each other student, which Xiao Xiao has never seen. Professor Wang said to Xiao Xiao, "This is the student I brought, your brother Zhang Heng."

Zhang Heng was wearing glasses and felt very gentle. As soon as Professor Wang introduced him, he greeted with a smile: "This is Xiao Xiao, right? I often hear the teacher mention you. The teacher said that my physical understanding is far less than yours, and please give me more advice in the future." It looks very amiable, but he didn't think so well in his eyes.

He has got a public study abroad in China and will go to study in M country soon. It can be said that thousands of troops have crossed the wooden bridge. How can he not be as good as a little girl who has just gone to college?

Xiao Xiao just pretended not to see it and greeted his brother with a smile.

Seeing that Xiao Xiao had listened to him, Zhang Heng didn't even have a word of humility. His smile remained unchanged, but he evaluated Xiao Xiao Xiao as a arrogant and impolite person in his heart.

"Let's go, the Tsingda car is coming." A car stopped at the gate of Peking University, and Professor Wang greeted everyone to get on the bus.

Xiao Xiao wondered, "Teacher, how can I get to Qingda University?"

When Professor Wang and the other two teachers heard this, they were suddenly a little embarrassed. At the beginning, they also listened to the robbery between Tsing University and Beijing University. To be fair, the Physics Department of Tsinghua University, whether teachers and others, far exceeded Peking University.

Now Xiao Xiao shows such a talent. If he had gone to Qingda at the beginning, he would have been better cultivated.

Professor Wang whispered, "This is the task assigned above. Tsingda is stronger, and the laboratory is also more advanced than our side, so this project is mainly based on Tsingda University, supplemented by us, and the two schools cooperate."

Xiao Xiao listened and said that it had nothing to do with the practical laboratory. She just wanted to go in and see if the laboratory was helpful for her dimension-hopping experiment.

But based on her understanding of the scientific level here these days, it is unlikely that the laboratory here can carry her experiment.

After Professor Wang said that, the other two teachers and he had been paying attention to Xiao Xiao's expression. Seeing that there was no regret on her face, he was relieved.

Qingda is not far from Beijing University, and the car arrived in more than 20 minutes.

If the gate of Peking University is simple and solemn and full of humanistic atmosphere, then the school gate of Qingda University is magnificent and neat and symmetrical and beautiful.

You can know the difference between the two schools just from the school gate.

Xiao Xiao raised his eyebrows. It seems that the teacher of Tsingda University was right at that time. Tsingda University was indeed better in science and engineering.

Someone answered Qingda.

The laboratory I'm going to this time seems to be very secretive. After half of the campus, I saw an independent yard in the depths of the campus. There were still many soldiers standing guard outside.

Xiao Xiao squeezed his lips. It seems that this project is not simple.

Professor Wang told Xiao Xiao, "When you enter the laboratory, don't tell the public anything you come into contact with."

Seeing Professor Wang's face serious, Xiao Xiao nodded.

The group has to go through a close inspection before releasing.

Xiao Xiao thought it was just to do a simple project on campus, but now it doesn't seem to be the case. She didn't tell Wang Wei when she left. If she couldn't find her, Wang Wei didn't know how to worry.

"Teacher, is it free to do this project?" Xiao Xiao whispered to Professor Wang.

Professor Wang smiled and said, "Of course, the inspection is so strict just in case. How can it restrict your freedom?" Don't worry, it won't make Wang Wei worry about you. Since she agreed that Xiao Xiao would participate in this project, she was naturally checked out. Professor Wang knew her background and social relations, so she joked Xiao Xiao.

Xiao Xiao was not shy at all: "That's good."

With that, the group had already entered the yard.

Xiao Xiao followed Professor Wang through the yard and entered a hall. The hall was full of more than 20 tables, and each table was full of people.

Everyone was very busy, reading words in their mouths, and the split of the abacus in his hand snapped.

Professor Wang said to Xiao Xiao, "These are all teachers and students of the Mathematics Department of Tsinghua University. They are responsible for auxiliary operations."

Abacus!

Xiao Xiao finally saw this ancient computing tool that has long been annihilated in the long river of history. She approached and watched a person dial the abacus quickly.

At a glance, you can know the operation speed. It can be calculated up to ten times a second. Looking at the residual shadow when the finger is dialed, but this kind of operation is too slow for Xiao Xiao.

It makes no sense to calculate the unit of time in seconds here. One second is enough for now human beings to measure anything.

But interstellar is not. A second is a very large unit of time, because there are too many things that can happen in a second to calculate at all. There are still more than a dozen levels of time units below.

Xiao Xiao looked up at Professor Wang, "Why don't you use a computer?" That should be called, right? She remembers that human beings should have invented computers at this time.

With her words, Professor Wang and both teachers laughed bitterly.

Zhang Heng looked at Xiao Xiao in a word: "Sister, do you know how scarcers computers are in China? At least there is one in Tsingda University, and we don't have one in Beijing University."

Professor Wang nodded, "Yes, computers are really scarce. The computer of Tsinghua University has also been borrowed to the Academy of Sciences. We just do some auxiliary projects and have to overcome them with abacus."

Professor Wang sighed heavily in his heart. If there were enough computers, who would be stupid to use the abacus?

"I heard that a new generation of computers have been developed in M country, with a computing speed of hundreds of millions or even a billion times per second. I don't know if it's true." Another teacher at Peking University said with infinite envy.

Xiao Xiao pumped the corners of his mouth. Is it fast to draw billions per second? She didn't expect that the computer level of M, which was regarded as a scientific benchmark, would be so backward.

The computer of human beings recorded in interstellar history is more than this level.

However, on the way, this is not China in the same space as the interstellar world. It can only be regarded as a parallel world, and the point deviation of the level of science and technology can be understood.

With such a slow speed, he was so envied by these teachers. Xiao Xiao had a bad association in his heart. He looked at the teacher and whispered, "What about China?"

"Millions of times per second are the fastest." The most important thing is that there is no energy production. There are not enough important departments in China at all.

Xiao Xiao: "..." Sure enough.

Just then, several people came out of the corridor on the side of the hall. They took a pile of paper and looked very anxious: "What's the matter? The results of this set of data you submitted before are not wrong at all. We can't match it after experiments!"

The operator in charge of the operation team is a middle-aged man. Just as he was coordinating the calculation in the hall, Xiao Xiao heard others call him Zhou Gong. Hearing this, Zhou Gong grabbed the data and muttered in disbelief: "Why is it wrong? We have calculated it five times. Is there something wrong in your experiment?"

"What's wrong with our experiment?" The man, led by coming out of the corridor, suddenly became angry when he heard the words: "Because of the set of wrong data you calculated, we have tested it several times, and each time it has deviated, which has wasted how much time!"

Zhou Gong sweated in a hurry. Hearing this man's words, he was even more anxious and said angrily, "Are you wasted your time?" Professor Xu, do you know how much effort we have put on to calculate the set of data you gave? Look at them. The fingertips dialed bubbled and finally formed a cocoon. Many of us have not been able to talk for three days and nights!"

"You didn't close your eyes for three days and nights. Do you think we were sleeping in the laboratory?" Because of the data was wrong, everyone was very anxious. This is the task explained above. In order to cooperate with the above experiment, they must complete these auxiliary projects as soon as possible. Unexpectedly, the first set of data went wrong.

It's okay for everyone to be tired, but if it delays the country's major events, they will die.

When you are anxious and tired, the fire in your heart naturally arches up easily.

The dispute between Zhou Gong and Professor Xu attracted everyone's attention, but Xiao Xiao noticed that everyone in the hall only looked up slightly, and the calculation in his hand did not stop at all.

There is a thick black blue in everyone's eyes.

They are too urgent to stop. The abacus in their hands seems to be a life-saving straw. What kind of experiment is this? How can it make these people so nervous?

Seeing this, Professor Wang hurried forward and advised, "Lao Xu, Lao Zhou, what are you doing? If you have these time to quarrel, it's better to calm down and find out what's wrong? You quarrel here. Can you quarrel here?"

Professor Xu and Zhou Gong heard the words, pressed their anger and woke up. Professor Xu apologized first: "Sorry, Lao Zhou, you know that our project can't afford to be delayed, and we are still waiting for data on it. I'm worried, that's why..."

Zhou Gong shook his head hurriedly: "I also want to apologize. I was too angry just now. Let's not talk about this. Find out what went wrong as soon as possible is the top priority. Fortunately, Professor Wang also came. Professor Wang, come and have a look. We calculated according to the data they gave, and we have calculated it several times. It is impossible to make mistakes..."

Professor Wang took it and looked carefully.

Professor Wang and Zhou Gong, and several other professors gathered together to find problems. Xiao Xiao and Zhang Heng stood in the hall with other teachers from Peking University.

Zhang Heng stood for a while and was a little anxious: "Teacher, aren't we going to join the experiment? Why do we stand here alone?"

The teacher of Peking University sighed, "Don't you hear that the project has encountered a bottleneck? If the problem is not found, it can't proceed to the next step. Let's wait first. When Professor Wang and others solve it, it will naturally arrange work for us."

At their level, in fact, it is to fight against professors, record data and so on. It is still up to Professor Wang and Tsinghua University to solve the problem.

Xiao Xiaoman thought she could enter the laboratory as soon as she came. Unexpectedly, she would stand here. She looked at the clock hanging in the hall and it was almost 11:30.

No, she has to go back to Wang Wei first, so that he won't worry.

But Professor Wang seemed to be busy for a while, and everyone in the hall was also competing for time to calculate. Everyone is so busy that it seems a little bad for her to say that she wants to go back for dinner?

Xiao Xiao walked to Professor Wang's table. If she could help them and solve the problem early, she could also say what she wanted to go back for dinner.

"Sister, what are you doing? Don't disturb Professor Wang and them. Seeing that Xiao Xiao had the courage to approach the responsible professors, Zhang Heng immediately lowered his voice to stop.

Xiao Xiao looked back at him, smiled, and her pace didn't stop: If she didn't go to see these people's motivation to forget to sleep and eat, when will she have to find Wang Wei?

"Teacher, look at Xiao..." Zhang Heng felt that Xiao Xiao was too unruly. The professors were discussing problems. What did she do?

The teacher of Peking University shook his head: "Let her go." They didn't expect Xiao Xiao to find out the problem. They just understood Xiao Xiao's learning ability and thought that this was a good opportunity to stay quietly next to those professors. Xiao Xiao's ability to understand part of it would also be of great help to her.

"Let's listen to it, but don't make a sound. Don't disturb the professor." Another teacher from Peking University said.

Zhang Heng nodded in a hurry.

Xiao Xiao walked behind Professor Wang and stood still without making a sound. She just stood up, and the two teachers of Peking University and Zhang Heng also came. They stood farther than Xiao Xiao. They were quiet and listened to the discussions of several professors very seriously.

The professors discussed it very seriously. They didn't notice that there was someone standing behind him at all. If they could enter here, at least there would be no problem with their identity, and everyone didn't have to be guarded.

Xiao Xiao stood for less than a minute and understood the problem they were arguing about.

The experimental group gave a formula for the operation group to calculate on the side, and the operation group calculated it. During the experiment on the experiment, it was found that the deviation was getting bigger and larger.

Therefore, it is inferred that the data calculated on the side of the operation group is wrong.

But the professors stroked it from beginning to end, but they didn't find out what was wrong.

"This set of formulas is wrong." Just as the professors were in full swing and were about to argue, a crisp voice sounded over their heads.

The professors who were so red-faced were quiet and looked up at the source of the sound.

A beautiful little girl stood behind Professor Wang and looked at them with bent eyes.

It seems that you are not more than 20 years old.

Professor Xu was anxious because he couldn't find out the problem. Xiao Xiao suddenly interrupted everyone's rhythm, and his face was naturally not good-looking. Seeing Xiao Xiao standing behind Professor Wang, he asked in a bad tone, "Lao Wang, is this your student?" Didn't you tell her the rules here when you came?

There is naturally a rule of hitting hands. Just say less and do more, just be careful and cautious.

Several other people believed that Xiao Xiao was making trouble. Through more than a month of frequent contact, Professor Wang knew that Xiao Xiao was not an aimless person.

Despite the anger of Professor Xu's other people, Professor Wang tentatively asked with expectations that he had never noticed, "Xiao Xiao, why do you say this set of formulas is wrong?" Can you understand?"

"Professor Wang, your students are nonsense, and you also follow nonsense? We don't waste any time!" Seeing that Professor Wang really followed Xiao Xiao's words and asked, Professor Xu and they were anxious and angry. What are they doing? It's not enough to race against time. Lao Wang is still fooling around with his students!
