In the conference room.
Everyone was lost in thought.
The mathematical content on the whiteboard is very clear. It is a difficult problem of a complex system of partial differential equations. The difficulty of the question is very high.
Even if there is one less unknown, it can still be considered a small study.
After adding an unknown number and a relational function, the difficulty of the question increases exponentially. If the question can correspond to a certain field of application, it is enough to apply for an outstanding youth-level mathematics project.
It is not easy to solve this kind of problem.
"It's precisely because of the difficulty that Wang Hao asked us to find a solution together, right?"
"It may be related to a certain research, but it is too difficult to solve this kind of problem, and it is unlikely to be possible in a short time...
"With so many of us studying together, we can at least find a direction."
"If this can help, maybe I can get a name on the paper? If it's related to some major application, it's hard to make a contribution. In this regard, Wang Hao is not stingy..."
"..."
This is one of the reasons why Wang Hao has appeal.
In many research fields, as long as you participate in the work of the research group, even if you make no contribution, you can at least have a name.
If there are contributions, they will be recorded in Eucalyptus.
In addition, Wang Hao has completed many major studies, and it seems that he can solve any problem in his hands. Everyone likes to do research work with him.
When everyone was about the same topic, Wang Hao began to explain, as if giving a lecture to students and said, "Let's take a look at this topic."
"A system of partial differential equations has one more relationship function than the conventional dynamic equations, that is, one more unknown number."
"Such an equation is very difficult to solve."
"I'm going to talk about a few conventional methods here, and everyone should think about it."
"The first one is..."
Wang Hao spoke seriously.
In the field of partial differential equations, he dares to say that he is the second in the world, and no one dares to say that he is the first, because he solved the NS equation problem among the seven major mathematical conjectures of the millennium.
His thinking is also very clear.
When faced with a complex system of partial differential equations, he continuously talked about five ways to approach the problem and then change it.
People in the conference room also followed suit.
Some of them are good at solving partial differential equations, such as Ding Zhiqiang, whose main fields are partial differential equations and algebraic geometry.
Some have not done much research on partial differential equations, but have been engaged in high-end scientific research fields and still understand the ideas for solving partial differential equations.
When Wang Hao explained in detail, their eyes lit up. There were some methods that they had not thought of, and they all felt that they had gained a lot.
When Wang Hao explained the fifth method, the correct information came back to his mind. His eyes lit up, he stopped talking, and said, "I just mentioned five methods of entry, but I personally think that the third method is The most ingenious and most likely to solve the problem.”
"Everyone come and see..."
"The constants of these equations are actually related to a certain extent. If we can make some transformations, like this..."
Although he just said to do some transformation, Wang Hao wrote on a whiteboard continuously, and then said, "Did you find out? If it is the first and fourth method, there will be problems with the transformation, but this method changes the formula The constants of 4 and 5 cancel..."
"The equation is simplified."
Everyone nodded in understanding.
After hearing this, they also felt that the third entry method was a very good choice, but they were not sure whether it could solve the problem.
Wang Hao asked people to bring in a new whiteboard and continued to analyze, "Our changes just now have eliminated two constants and simplified Equations 4 and 5. The next step is to solve it."
"This step is not easy either."
It was not easy for him to talk, but the pen in his hand never stopped, "We need to substitute equation 3 and equation 2 to see if we can eliminate an unknown variable in the main equation."
"Let's continue changing..."
Wang Hao explained while analyzing.
Everyone keeps up with the ideas and understands them carefully.
Although Wang Hao's analysis speed is very fast, with the bonus effect of "The Gift of Teaching" and the fact that everyone present can be said to be top scholars in the fields of mathematics, physics, computers, etc., even Zhang Zhiqiang, who is less advanced, can understand it. .
They nodded frequently while listening, "Yes, that's it. In this way, the unknowns may be eliminated."
"It makes sense. This method is very good."
"It's the same as what I thought. That's what I thought just now."
"..."
Wang Hao continued to analyze.
His analysis filled a new whiteboard, and finally he came up with a function, and then made a simple function diagram so that everyone can see it more clearly.
At this time, the relationship between the three unknowns of the equation has been found.
Many people were immediately shocked.
Paul Phil-Jones said in surprise, "If we substitute Equation 1 again, wouldn't we be able to find the value of γ?"
"Yeah, let's find a value!"
"In the final search for the functional relationship, the single value of γ is also very important. Substitute it into Equation 3, and you can get the relationship with β..."
"Wouldn't the problem become simpler?"
"..."
They were discussing in surprise, and suddenly felt something was wrong.
How did it come to this?
Doesn’t this mean more than half of the problem is solved? The problem has become much simpler. If we continue... won't it be solved?
The expressions of some people who understood became obviously strange, but they continued to understand.
Wang Hao didn't pause at all.
When this step is reached, the inspiration value has exceeded 90 points, and the direction to solve the problem has been found. Just continue to analyze it.
He continued to analyze it, as if giving a lecture to students, and while he continued to explain, the third whiteboard was full again.
When a new whiteboard was brought up, he directly summarized the previous content into a simplified system of equations on the whiteboard, "From the beginning to now, the relationship has been clearly sorted out."
"Look at this simplified system of equations..."
"The difficulty of the question is very high, but if you think more about it, you can always come up with a solution..."
"Let's continue..."
In fact, there is no need to continue at all.
The difficult parts have been solved, and even if Zhang Zhiqiang were asked to take part in the remaining tasks, he would be able to follow his train of thought and come up with an answer.
The difference is just time.
Wang Hao solved the problem very quickly. Because the research was completed and the inspiration value exceeded 100 points, he stopped explaining and started writing the answer directly.
After using the fourth whiteboard, he finally listed the functional relationships between several unknown variables such as power, altitude, and speed.
This is the result.
After finishing writing the results, Wang Hao smiled in front of everyone and said, "Look, everyone, this completes the solution to the problem. So when faced with a problem, as long as you think more, you can always solve it..."
"..."
"..."
The expressions of people in the conference room were a little numb.
At first they thought Wang Hao had encountered a problem, so they asked them to do research together. But after listening for more than an hour, the problem was solved?
Is this Wang Hao’s new achievement?
Are you lecturing them?
The gains from this class are indeed not small. At least they have learned a lot about solving partial differential equations, but...why does it feel like something is wrong?
Why did it become a class?
Chen Mengmeng, Zhang Zhiqiang, Luo Dayong and others didn't think so. They all knew that the question was given by Teacher Zhou.
In the end, Wang Hao solved it so quickly?
I also gave them a lesson on complex partial differential equations!
"What kind of brain does this guy have?"
"Such a difficult question..."
"If I hadn't seen it with my own eyes, I wouldn't have believed it."
"But why are we here, just to listen to the lecture? Why do I feel weird..."
"It's not a lecture."
Zhang Zhiqiang took a deep breath and said in a conclusive tone, "I feel like this guy asked us all to come here just to see him pretending to be sexy!"
…
Teacher Zhou took a picture of the math content on the whiteboard with her mobile phone and took the 'problem-solving process and answers' with her on her way back.
Along the way, he was a little confused.
Even if he overestimated Wang Hao's ability, he never thought of such a complicated problem and solved it in just over an hour.
The experts from the power team spent more than two weeks doing research but to no avail.
Wang Hao......
about an hour?
Teacher Zhou returned to the experimental base in shock. He immediately found Ruan Xingping and said, "It was like he was solving a simple math problem."
"The ideas have always been very clear. I wrote the answer from beginning to end, as if I knew how to solve it from the beginning..."
"He also gave a class to a group of professors, including Paul Feier, Ding Zhiqiang, Luo Dayong..."
"..."
Ruan Xingping felt as if he had heard a joke. He knew very well how difficult it was to solve the power balance problem, but he could not completely disbelieve it.
Teacher Zhou really didn’t take long.
He could only read the content with doubts, and called others to analyze it, but found that it was difficult to make a judgment in a short time.
This is mainly because the problem-solving process is complex.
Wang Hao spent more than an hour explaining. His explanation was very detailed. Coupled with the understanding bonus of "Feedback on Teaching", people in the conference room could follow the thinking.
The power pack is different.
They look at the content and then understand it.
In addition, their average level is relatively poor.
In the Mason Mathematics Laboratory, everyone who is qualified to participate in Wang Hao's research can be said to be an elite. Even Zhang Zhiqiang, who is relatively inferior, graduated from a prestigious university with a doctorate, and has been doing research in the field of mathematical computers for so many years. , the level is naturally not much different.
If Zhang Zhiqiang is placed in the power group, he can still be at an above-average level.
Therefore, it still takes a lot of time for people in the power group to understand the process, so they simply start with the results and compare the results with the experimental data.
Then it was discovered that the deviation was very small after substituting the numerical values.
This made the people in the power team feel incredible. After Ruan Xingping confirmed the result, he sat in his position for a long time without moving.
He began to doubt life.
Not only are the power team elites, but they are also related scholars. They spent more than two weeks on a problem that they couldn't figure out, but it took only one hour for Wang Hao to solve it?
Most of the one hour was spent solving problems and explaining.
in other words……
Wang Hao knew how to solve the problem from the beginning. He just wrote out the process and explained it to the people in the Mason Mathematics Laboratory.
This gap is too big!
Teacher Zhou ignored the mood of the motivation group.
After the power team confirmed that the process and results were correct, he immediately handed over the work and found the computer team to ask them to convert the answers into computer language.
In this way, the electronic system can perform automatic calculations, which solves the biggest problem of Kongjian-2 testing stealth technology.
…
at the same time.
International public opinion continues to ferment around the stealth technology of Kongkan-2.
The overwhelming reports in the media let everyone know that Kongjian-2 possesses a high-end stealth technology that is suspected of 'creating a strong annihilation field'.
Under such turbulent public opinion, some relevant leaders also stood up and said, "We are experimenting with a brand new stealth technology."
"This invisibility technology is related to annihilation technology."
"But this is just a normal technical experiment, an exploration of high-end technology. It has nothing to do with the international situation and will not threaten..."
What happens next is not important.
The relevant boss came forward to confirm the news, which immediately attracted public attention.
Although there are many photos and videos on the Internet, and everyone knows the news through speculation and analysis, the relevant boss's statement is directly qualitative.
Suddenly, the attention of Kongjian-2 became even higher.
Of course, those professional institutions are not only concerned about public opinion, they are also more concerned about the technology contained in it and the threats it can pose.
The technical aspects are clear.
Kongjian-2 is based on the transverse anti-gravity field and creates a strong annihilation force field of a certain intensity, which is not very strong from the outside.
An expert who has participated in the International Annihilation Theory Organization evaluated, "The inner layer strength is above 3 times, but it will definitely not reach 4 times."
"This intensity is enough to annihilate all electromagnetic waves."
"In other words, all radars capable of long-range detection will lose their effectiveness..."
This is the threat.
When the technical analysis is thorough, the threat is real.
The Kongjian-2 was previously considered the nemesis of aircraft carriers, because the Kongjian-2 can fly high enough to ensure safety, and its bomb load is also very impressive. In theory, it can carry out coverage strikes against aircraft carriers.
However, a theory is just a theory after all.
Kongjian-2 cannot carry all high-end missiles with locking functions. For missiles without locking functions, bomb delivery must be accurate.
When bombs are dropped at an altitude of 30,000 meters, the accuracy will be pitifully low.
It's different now.
With the stealth technology of Kongjian-2, it cannot be locked by conventional radar and does not need to be suspended at high altitude. It can just hover and drop bombs overhead.
At that point, it’s time to hit with precise coverage.
Faced with aircraft that cannot be locked by radar and carry a large number of missiles, the huge aircraft carrier has truly become a living target.
How to fight it?
The only way they thought of was to use fighter jets to fight, but the air-to-air missiles could not lock on to the target, so they had to rely on the pilot's operation.
However, the flexibility of the fighter aircraft may not necessarily match that of the Kongjian-2.
If the other party carries out a surprise attack at night, they will not even have time to react because the radar cannot give a warning in advance.
This is only for aircraft carriers.
"What if Kongjian-2 carries out a nuclear bomb delivery mission?"
"The anti-missile system will be completely ineffective, and military bases will become targets, allowing the other party to attack at will..."
"There is no way to defend effectively!"
Everyone was in a cold sweat just thinking about it, and some people couldn't help but suggest, "I think the upcoming exercise plan can be a little more low-key."
"Yes, keep a low profile."
"We cannot let them think it is a provocation..."
In fact, there was no need to command at all. General Witton, the person in charge of the exercise, had already decided to keep a low profile and even refused all interviews.
The interview was planned before.
They conduct public exercises to achieve the purpose of deterrence, and then allow reporters to interview and film openly to achieve the purpose of demonstrating force to their opponents.
It's different now.
When he learned that the other party had the ability to hit him with coverage, his mentality immediately changed when he launched the exercise.
It's like two people having a conflict, with one party showing off its strong muscles towards the other.
The other party directly pulled out a gun.
What to do?
I can only keep a low profile...
