The next morning, in the library!

Zhuoyuexindao: "The heat conduction equation is divided into three latitude heat source heat conduction equations and three-dimensional heat conduction equations without heat sources. These two equations, heat sources, are called non-homogeneous heat conduction equations, and those without heat sources are called homogeneous heat conduction equations."

"First of all, we need to know the law of conservation of heat. The heat absorbed by temperature changes = the heat emitted by the heat source flowing in through the boundary."

"The second is Fourier's law of thermal conduction."

As he said that, he picked up a pen and wrote it on paper.

【dq=-k(x,y,z)?u/?ndsdt】

"And the calorie formula."

【q=cmu】

“…”

【…】

"So the final three-dimensional heat conduction equation is."

【?u/?t-a2(?2u/?x2?2u/?y2?2u/?z2)=?(x,y,z,t)】

"The three-dimensional heat-free heat conduction equation is."

【?u/?t-a2(?2u/?x2?2u/?y2?2u/?z2)=0】

He put the pen in his hand aside and thought to himself: "It's solved it like this. It's still very simple to use the Black Scholes model to deduce the heat conduction equation, and it's not as complicated as turbulence."

The heat conduction equation is one of the classical physics, and the only thing that classical physics is not solved is turbulence, and the rest are solved.

Of course, turbulence has been solved by excellence now, but as long as he does not disclose his research results on turbulence, people from the outside world will not know that turbulence is still a knowledge that classical physics has not been solved.

[Congratulations to the host for deriving the heat conduction equation!

Reward: One knowledge card!]

[Task: Scientific conjecture - independently constructing Coulomb’s law!

Reward: One knowledge card, IQ 2!]

"Coulomb's Law?" Zhuo Yue was puzzled, "Is the system asking me to do electromagnetic field theory?"

With his understanding of the system for so long, the system allows him to complete the most basic tasks in a certain field, and then deepen the difficulty step by step until the final tasks in a certain field are solved.

Coulomb's law is the basic equation of electromagnetic field theory, so it is obvious that the system is asking it to engage in electromagnetic field theory.

"What's the point of doing with electromagnetic field theory? Haven't it been solved?" He was puzzled.

The electromagnetic field theory is also one of the classical physics and has also been solved.

He couldn't figure out what there was to do with a solved theory.

If the system asks him to derive the final equation of the electromagnetic field theory, he can directly copy the final equation of the electromagnetic field theory.

"Is it a bonus question?" His eyes suddenly lit up.

This is the only possibility, after all, a theory that has been solved has nothing to study.

"It's good to give away points, I like it the most."

The bonus question is the question before you, so don’t want it in vain.

But he soon knew that he had understood it wrongly. He only paid attention to the four words Coulomb's Law, but did not pay attention to the four words scientific conjectures.

No matter in any discipline, scientific conjecture is not simple knowledge. It takes decades or even a hundred years from the time it is proposed to the point of being deduced.

Take one of the seven major conjectures in physics, Lorentz's invariance conjecture, for example, as proposed in the early 20th century, but it has not been proven for more than a hundred years.

The same is true for the other six conjectures, from which we can see the difficulty of scientific conjectures.

"Look at what the knowledge card can give me first!"

After talking about it, use the knowledge card.

【Basic electromagnetic field knowledge!】

"What?" Zhuoyue was surprised, "No, just give me this?"

At this time, the phone that Zhuoyue put aside rang!

He picked it up and looked at it, and said in confusion: "Hmm? Who is this?"

He didn't recognize the number on his phone, but he still connected.

"Hello!"

"Is it Zhuoyue?" A familiar voice came from the phone, but Zhuoyue couldn't remember who it was.

"It's me, are you?"

"I am Di Guodong!"

"So it's the principal. Are you asking me for something?"

"If you are convenient, come to my office at 2 pm!"

"Principal, is there anything wrong?"

"Do you have a deep study of turbulence?"

"It's not a very deep study, it's just a little understanding!"

"I won't beat you around the bush. I have a friend from the Magic City. He is from China International Airlines and I want to talk about cooperation with you."

"Talking about cooperation with me?" Zhuo Yue said in confusion: "Principal, I have no money, no resources, and no technology. What should I do with them? Do I ask me to help them build planes? I can't do it either!"

"It's not that you are asking you to build planes, it's to help them solve the problem of turbulence."

"Oh, so that's how it is. OK, I'll go to your trip in the afternoon."

If it is a turbulence problem, he will definitely have no problem. After all, he has deduced the turbulence equation, and no turbulence will be of any difficulty to him.

"Yeah, okay, that's it, I'm dead."

The principal hung up after saying that, Zhuoyue put down his phone with a smile, and felt very happy.

"I didn't expect that I would get money so soon. I also enjoy the treatment of a science professor!"

As far as outstanding knowledge is concerned, any capable science professor in the school is rich.

Don’t look at the fact that university professors are poor every day on the Internet, that’s all nonsense.

The annual income of professors is beyond your imagination. Take Professor Yang for example. In addition to the school’s income, there are also scientific research funds and technical cooperation with many companies, as well as being technical consultants.

The technical consultant does not say that he goes to work in those companies every day, but that he will look for him when he needs them, and when he doesn't look for him, he will still have to pay for money to support him for nothing.

I only look for him a few times a month, and the problems I need to solve are all small problems.

Professor Yang also has many technical patents in his hands, and the key is that these technical patents are also researched using scientific research funds provided by the state.

According to the contract when the scientific research project was established at that time, some unimportant technologies Professor Yang can handle them by himself, or use scientific research funds to study some technologies.

Whether Professor Yang sells them or works with certain companies, he makes a lot of money.

Just relying on this, Professor Yang's annual income is tens of millions.

Not only Professor Yang does this, but professors from universities around the world do this. Otherwise, relying on the school’s salary, few professors are willing to be teachers.

Although poetry and the distance are important, reality is more important.

Of course, only capable professors can do this. Each university has no shortage of professors who do not have real talents and knowledge. These professors can only receive a dead salary and can make up for scientific research funds at most. However, this is a crime and is found to be in prison.

At two o'clock in the afternoon, Zhuoyue knocked on the principal's office. After hearing the invitation, he pushed the door and went in.

At this time in the office, the principal was sitting on the sofa drinking tea with a middle-aged man in a suit and a little white hair.

"Zhuoyue, come here, sit down!" The principal pointed to the sofa next to him.

After Zhuoyue sat down, the principal wanted to pour him tea. Zhuoyue quickly stood up and said, "Principal, I will do it myself, you don't have to be busy."

But the principal still held the teapot, and he could only pick up the cup and hung it in the air to pick up the tea.

"This tea is a little different from the last time, try it!"

"Oh, OK, thank you Principal!"

Zhuoyue sat down and tasted the tea carefully. After he took a sip, the principal asked, "How is it, it tastes good!"

"It's really good, sweet and cool, it's best to drink this summer."

In the past, Zhuoyue had no conditions to drink good tea. After the principal drank it twice, Zhuoyue fell in love with it a little.

When you have money, you will get some tea when you have the chance.

The two most popular drinks in the world are coffee and tea.

But in terms of price, tea is the most expensive, and some of the most expensive teas are priceless and cannot be bought even if you want to.

The three of them savored the tea carefully and talked about family matters. Zhuoyue had been observing the middle-aged man opposite him. He knew that this might be a member of China International Airlines.

The middle-aged man is also paying attention to Zhuoyue. He is curious about Zhuoyue and does not know why he is praised by the president of Zhejiang University.

About ten minutes later, the principal pointed to the middle-aged man and said, "Zhuoyue, I think you have guessed that he is Li Datian, vice president of China International Airlines. The aviation field is the most affected by turbulence. Their company suffers from turbulence every year by hundreds of millions of damage to turbulence. So after hearing that you have a deep research on turbulence, I want to ask you to be their consultant."

"The consultant is OK." Zhuoyue said: "Don't you know what assessments Mr. Li needs to give me?"

Although he derived the n-s equation and the turbulence equation, few people knew about this.

So, he was sure that if he wanted to become an advisor to China International Airlines, he had to face the test.

The middle-aged man took out a piece of folded paper from his pocket, unfolded it and saw many formulas and words written on it, and put it in front of Zhuoyue and said, "Please solve the problem above."
Chapter completed!
