Research starts with PhD students

Chapter 220: Watching the explosion in the sky? It seems very interesting!

A special meeting was held at the experimental base.

The meeting place was in a larger house among the blue-roofed bungalows at the foot of the mountain. Various electronic equipment were placed on the sides of the room, and several tables were placed in the empty space in the middle.

On weekdays, project technical meetings are held here.

Although the building is relatively simple, the equipment is still very high-end, and there are all kinds of electronic equipment in the conference room.

Each participant was also provided with a laptop.

After everyone entered the room, they found a seat and sat down. Teacher Wang also sat at the edge with great interest. He planned to listen in on what was to be discussed.

Tong Zhiguo and Lu Ling sat together closest to the podium.

The others are the heads of various departments and technical and experimental researchers, including six researchers and seven engineers, two technical representatives, experimental management, equipment management, etc., a total of twenty-three people.

Zhang Shuo stood on the podium with some information. He fiddled with the computer and uploaded the information. A line of research titles appeared on the screen.

"Calculation of the balance between ion cluster excitation and air loss".

Although it is not a formal report, it is still in the form of a report so that others can understand it better.

When the meeting room quieted down, Zhang Shuo said directly, "This meeting is to discuss computing content."

He pointed at the screen behind him and said, "Everyone has seen the title. It is the balance calculation between ion cluster excitation and air loss. You should understand it, right?"

Although the words were questions, the tone was affirmative.

The room suddenly became noisy.

Many people who just learned the news were a little surprised. They have held many technical meetings to solve the current problems, and the direction they discussed most was to accumulate data through basic experiments in order to find a balanced parameter set while ensuring safety.

Zhang Shuo's research obviously skipped the experimental stage and directly calculated the results.

Mathematical calculations are definitely more accurate than experimental research, and being able to solve a problem through calculations is equivalent to getting the problem done in one step.

If someone else had said to do the calculation directly, they would have questioned, "How can you guarantee the accuracy of the calculation results?"

"If there is a small mistake in this experiment, it will cause big problems!"

“Safety is the most important thing!”

Everyone is very concerned about safety.

Many people in the project team had worked with Tong Zhiguo on the previous verification, and some were equipment operators hiding in the air-raid shelter.

That experience was truly horrible.

I originally thought it was a harmless experiment, but soon after I entered the air-raid shelter, I heard a loud explosion outside. The air-raid shelter was vibrating. The sound alone can damage the human eardrum, so you can imagine how dangerous it is.

Having had such an experience, one naturally understands the dangers of experiments.

Therefore, solving the problem by mathematical calculation was even excluded as an option by the project team.

However, the narrator was Zhang Shuo.

This is different.

The experiments they are currently conducting are applied technology research based on Zhang Shuo's theory.

At the same time, Zhang Shuo is also recognized as one of the world's top mathematicians. With him doing the calculations, the credibility is naturally greatly improved.

After Zhang Shuo briefly introduced the content, he calmly waited for the room to quiet down again, and then said, "If you have any questions during the explanation, please feel free to ask."

“We discuss this together.”

"This experiment is very dangerous. Miscalculation can have serious consequences. You should be aware of this. So if you find any mistakes in my calculations, you should point them out on the spot."

What he said was very humble and also gave courage to others to ask questions.

Many people breathed a sigh of relief when they heard this.

Tong Zhiguo also thought of the same problem. He was worried that some people would find the problem but not say it out. Because the question was asked to Zhang Shuo, some people might think that Zhang Shuo was unlikely to make a mistake, and then it would be their own fault.

That's bad.

Now that Zhang Shuo has said it directly, he doesn't have to be the bad guy anymore.

The explanation officially begins.

A set of relationship diagrams appeared on the screen, which contained factors related to balance calculations and included a lot of complex content.

For example, the most direct air resistance.

This part of the calculation involves fluid mechanics, and the air resistance encountered by the ion clusters that emit heat makes the calculation more complicated.

For example, field forces will cause reactions in air particles.

Air particles will also be affected by the field force and undergo nuclear fission, which will also cause the air passing through the path to heat up and bring about instantaneous changes.

In addition, the energy change during the passage of the ion cluster is also one of the core factors. The field force reaction of the ion cluster must be maintained, and there must be no obvious energy reduction.

and many more.

After analyzing the influencing factors, Zhang Shuo began to explain one by one.

First, let’s start with air resistance.

This part even made most of the participants feel confused. Some of them had some exposure to research in fluid mechanics, aerodynamics, etc., but the calculation of resistance generated by high-speed collisions between ion clusters and air seemed completely beyond their scope.

Zhang Shuo analyzed step by step, explained the factors involved, and began the first wave of explanations patiently.

……

Everyone in the room listened attentively, but listening attentively does not necessarily mean understanding.

Tong Zhiguo couldn't understand the first part less than halfway through the explanation, because it involved very complex applications and calculations of partial differential equations, and he had never studied this field.

Even the expression of the resistance of ion clusters was not clear to him whether it was right or wrong.

There are still professionals in the audience.

Lu Ling listened very carefully and even took out a pen to write and draw on paper.

When Zhang Shuo finished speaking a small part, Lu Ling raised his hand and said, "Professor Zhang Shuo, can you please repeat the part about conversion?"

Others followed suit and said, "It's that part of the conversion that I don't understand either."

"Tell me again."

"Ok."

Zhang Shuo nodded indifferently and continued to explain it slowly.

Lu Ling was the first to ask Zhang Shuo to explain it again, and the others followed suit and pointed out any parts they did not understand.

This also led to serious delays in the explanation.

I thought it would only take half an hour to explain the whole thing, but in the end it took more than an hour to finish.

Zhang Shuo took advantage of the break to think carefully and realized that this was normal. Most of the people present were experimental personnel, and a few were engineers, not scholars doing research in the field of partial differential equations.

If it were Luo Yongjun or Li Weihua, perhaps it would be enough to go through it once. As long as they made sure there were no problems with the steps, the correctness of the calculation results could be verified later.

……

Zhang Shuo spoke for more than four hours and spent the entire afternoon in the conference room explaining continuously.

It's already dark outside.

At this time, Tong Zhiguo just felt dizzy and dazed. He kept trying to understand the content of each part, but he understood some of it and some of it not.

Listening to the calculation process now seems more tiring than doing ten experiments.

Lü Ling was relatively better, he also listened to the whole process and understood most of the content. The others understood what they could.

The whole explanation process was that Zhang Shuo spoke first, the audience raised the difficult parts, and then Zhang Shuo focused on that part.

Teacher Wang had already left.

He originally thought he could sit in for a while, but in fact he couldn't stand it after just half an hour because he couldn't understand the content at all and felt that he was just there to make up the numbers.

By the time the whole explanation was finished, it was already pitch dark outside.

A group of people walked out of the room.

Teacher Wang was standing under the light. When he saw Tong Zhiguo walking in front of him, he immediately went over to him and asked with concern, "What was the result?"

Tong Zhiguo had a look of despair on his face, sighing as he walked, making people feel that he was in a heavy mood.

"No? Have you found the problem?" Teacher Wang asked doubtfully.

Tong Zhiguo quickly shook his head and explained, "No, it's no problem."

"Then what are you...?"

Teacher Wang was a little confused about the situation, and he looked at Lu Ling behind him.

Lu Ling took his eyes off the manuscript in his hand and said, "Professor Zhang Shuo's calculations are clear and well-organized. There are no logical loopholes, and the calculated values ​​are also very accurate."

"Everyone's comments are very high. We should be able to conduct experiments based on the calculation results."

Teacher Wang was confused. He pointed at Tong Zhiguo and asked, "What's the situation with Academician Tong...?"

"I'm fine."

Tong Zhiguo immediately spoke up. "I'm just in a bad mood... Alas~~~"

As he sighed, he heard someone passing by chatting, "With so much content and such complicated calculations, Zhang Shuo finished it in just a few days?"

"If I remember correctly, he's only been here four days? Or, five days? Is that right?"

"Let alone four or five days, I feel like I can't finish it even if I'm given a year."

"I will never be able to complete it in my lifetime. If it were me, I would definitely make mistakes along the way. And the first part, the complicated partial differential equation... He actually found an exact solution?"

"This is the difference. Professor Zhang Shuo is indeed a top mathematician. No wonder he got the Fields Medal!"

"People always say 'three incompetent generals are better than one Zhuge Liang'. Even if there are ten people like me, they are not as good as Professor Zhang Shuo alone."

"One hundred is not enough!"

Teacher Wang looked at Tong Zhiguo again and immediately understood. He said to Lv Ling and Tong Zhiguo with a smile, "You don't have to be like this. Zhang Shuo will say that he is a top mathematician, but you don't do this."

Lü Ling and Tong Zhiguo just felt a little relieved when they heard Teacher Wang continue, "Even if you study mathematics, there is a gap between studying mathematics and studying mathematics."

"I have heard a story about Gauss. It is said that Gauss's teacher gave him homework, and one of the problems in the homework was to draw a regular 17-gon. Gauss solved it in one night."

"After he solved it, he realized that it was a problem that no one had solved for thousands of years!"

"Zhang Shuo is Gauss, how can we compare? Can others solve the same problem in a few nights or a few years?"

"So we have to face up to our own ordinariness! Look at me, I just realized I didn't understand and left."

Tong Zhiguo and Lu Ling looked at each other and couldn't help but say, "Teacher Wang, I know you want to comfort us, but... these words you said really don't have any comforting effect."

Teacher Wang smiled and said, "I was just telling a story and making an analogy."

Zhang Shuo walked out of the room, he was obviously a little tired.

Teacher Wang immediately walked over and said, "Congratulations, Professor Zhang Shuo, you have completed another important research."

Zhang Shuo shook his head indifferently, "This isn't an important study, is it? I just did some calculations."

Tong Zhiguo and Lu Ling's faces turned even darker.

Zhang Shuo said, "The most important thing is to make sure that there are no problems with the calculations and that the data passes, then we can conduct experiments to verify it."

This sentence immediately made Tong Zhiguo perk up.

Teacher Wang was particularly concerned about the experiment. He immediately asked, "Now that the calculations have been completed, how long will it take for the experiment to be carried out?"

"Three days!"

Tong Zhiguo replied, "Three days of preparation is enough. The equipment mainly needs to adjust the parameters, and some other preparations need to be made."

"Detection is the most important thing. The detection of ion clusters must be arranged in advance."

He added, "We still need the military's cooperation this time!"

Teacher Wang immediately said, "That's no problem, don't worry, I have arranged everything."

"Three days, not much."

"I'll wait here for three days!"

……

Tong Zhiguo said that what needs the military's cooperation is to find the landing point of the ion cluster.

The ion cluster will be carried to an uninhabited area dozens of kilometers away, and its trajectory will be captured by a high-precision camera, but only the approximate falling location can be known. If you want to find the exact location and the fallen residues, a large number of manpower will be needed.

The last time we searched for dropped remains, the military also cooperated.

The project base does not have this capability.

After Zhang Shuo's calculations were finalized, the project team began to prepare for the next experiment. Zhang Shuo also participated in the experimental preparations. He watched every process with great interest.

Simply put, the whole process is to create ion clusters and control the acceleration of the ion clusters in a circular accelerator.

After reaching a certain speed, the ion cluster is controlled to pass through the reaction magnetic field belt, and then rush out of the vacuum channel and ejected from the outlet.

"If the experiment fails, it's really troublesome to find the ion cluster remnants."

"A small mass of matter reached tens of kilometers away. After reaching the target area, there may be a lot of similar things, and we don't know where exactly the residue is."

"On the contrary, if the experiment is successful, it will be different, and there will be no need to look for it at all."

Before the experiment started, Zhang Shuo and Teacher Wang took a car away from the experimental base and kept talking about the experiment on the way.

Teacher Wang asked in confusion, "Why don't you look for it?"

"Because there will be an explosion!"

Zhang Shuo smiled and said, "It's not clear what kind of explosion it is, but it will definitely be easy to see."

Teacher Wang's eyes lit up when he heard this. "In other words, if the experiment is successful, then we can directly carry out technology transformation?"

"It still depends on the intensity of the explosion. In actual application, military standards, how to coordinate with radar and other equipment, and how to adjust are all things that need to be considered. However, as far as the technology related to the experiment is concerned, there should be no problem."

"that's great!"

Teacher Wang said, "I'm kind of looking forward to an explosion."

He suddenly suggested, "Why don't we take a helicopter and look from the sky. It will definitely be clearer."

"Uh~~~"

Zhang Shuo was immediately moved after hearing this.

The experiment is likely to explode, let's go to the sky and take a look...

It sounds like it's very interesting!
