The distance between Rome and Paris is more than 1,400 kilometers, and the fastest flight takes about two hours.

Qin Ke and the others chose the fastest direct flight.

For Qin and Ke, who are used to taking long-distance international flights, two hours is already a short time. The two of them sat in the first-class cabin and continued to study the general solution of the Yang-Mills equation. Wei Feng and Wei Jing were naturally sitting next to each other.

Both are nearby.

In fact, in order to ensure the safety of Qin Ke and Qin Ke to the greatest extent, there are a total of eight seats in the first class cabin. Seven of them have been reserved by Wei Feng and his colleagues. Only one seat has been reserved by someone else before and it is really impossible to grab it.

.

This "individual" passenger, who looked like an Italian scholar, was sitting in the front row reading a journal, wearing thick reading glasses, a few seats away from Qin Ke.

Wei Feng and others were responsible for security issues. Qin Ke and Ning Qingyun didn't pay attention to the old scholar. They kept their heads down writing calculations and exchanging words in low voices from time to time.

This is the fun and convenience of mathematics. It does not require any experimental equipment, and does not choose time or place. As long as there is a pen and paper, there is a "research laboratory" anywhere. So from the beginning of June to the end of June, the two of them have free time.

Most of them can be devoted to the study of general solutions to the Yang-Mills equation.

The "Lime Tsunami Storm Flow Circulation Algorithm" is indeed the world's top mathematical processing method for partial differential equations. Even the most difficult direction of nonlinear partial differential equations is still extremely effective. The Yang-Mills equation was used by the two of them.

There are already signs of defeat under the pen. Qin Ke estimates that if he concentrates on studying, it should not be a problem to solve this problem of general explanation by the end of July or early August.

Seeing that the flight had passed an hour, Qin Ke stretched out, put down his pen, and pulled Ning Qingyun to stand up and move his hands and feet to avoid the negative impact of sitting for a long time on the body's blood circulation.

The space in the first class cabin is relatively large, and there is no shortage of drinks and fruits. Qin Ke picked the cleanest grape and fed it to Ning Qingyun. Ning Qingyun gently bit it with her white and neat little teeth and gave him a sweet reply.

smile.

The two of them were moving their hands and feet while whispering about the problems they had just encountered in the Yang-Mills equation. Suddenly they heard someone asking in English: "Excuse me, these two are academicians Qin Ke and Ning Qing from Xia State.

Academician Jun?"

Qin Ke and Ning Qingyun unexpectedly turned around and saw the old Italian scholar who was sitting in front of them. It looked like he had just come out of the bathroom.

This old gentleman looks to be in his sixties, with gray hair, but his eyes behind his glasses are still blue, and his facial features are deep. It can be seen that he must have been quite handsome when he was young.

Qin Ke recognized him immediately. He took off his sunglasses and said in English in surprise: "Yes, I am Qin Ke. Sir... Professor Campol from Sapienza University of Rome, right?"

The day before yesterday, he and Ning Qingjun held a lecture at the Sapienza University of Rome. Professor Campol was sitting in the first row of the lecture hall. The reason why Qin Ke recognized him was because of the close distance and he often looked at him during his lectures.

Through the contact, and during the question-and-answer session, Professor Campol asked a very competent question, which left a deep impression on Qin Ke.

Qin Ke said and gave Wei Feng and Wei Jing a nonchalant look as they stood up quietly.

Mr. Campbell got on the plane relatively late, so naturally he didn't see Qin Ke and Ning Qingyun, who were sitting relatively far back. Moreover, they were wearing hats and sunglasses. He was not familiar with their appearance but stared at them carefully.

It's unrecognizable.

This time he got up to go to the bathroom and on his way back, he happened to hear someone talking in Mandarin. It is rare to hear Chinese on a European flight and in the first class cabin. The old gentleman looked at the two of them curiously.

, recognized what seemed to be Qin Ke and Ning Qingyun, and stepped forward to talk.

He took out his business card, handed it over with both hands, and said with a smile: "Academician Qin's memory is really amazing. If I remember correctly, I only asked a question once in your public lecture the day before yesterday. I didn't expect you to remember it now. Part 1

There were too many people around you in this lecture, so I didn’t have the chance to send you my business card. Let me introduce myself formally. I am Rudene Campol, a professor at the School of Physics at Sapienza University of Rome. My main focus is condensed matter physics.

I am not very familiar with fluid mechanics, but I have a certain understanding of it. Your special lecture on the n-s equation the day before yesterday was very good."

"It's an honor to meet you." Qin Ke took the business card and put it away with both hands, and shook hands with the old gentleman: "I didn't expect to meet you on this flight."

Professor Campol smiled and said: "I am going to Paris to participate in the Science Breakthrough Award. You and your wife should be in the same destination, right?"

"Yes. Professor Campbell also wants to go on stage to give a report? Or will he participate in the award selection?"

Professor Campbell shook his head and smiled: "I am just a spectator and will not participate in this year's selection. The two of you have a high voice for winning this year's Physics Breakthrough Award. I will look forward to your report." In fact, he is.

One of the special judges for this year's Breakthrough Prize in Physics, but the identity of the judge is not allowed to be disclosed before the award is announced, so he did not reveal it.

After a brief chat, Qin Ke discovered that Professor Campol's level in physics, especially condensed matter, was very high, almost as good as Professor Koppet from the University of Munich. The more the two chatted, the more they became more and more speculative.

Because it was not convenient to chat while standing, Qin Ke asked Wei Feng and Professor Campbell, who were sitting next to the aisle, to switch seats.

Wei Feng had just stood up. Before Professor Campbell could sit down, the plane suddenly shook violently.

Ning Qingyun was unprepared and suddenly screamed and almost fell down. Qin Ke hugged her quickly and helped her sit down, asking with concern: "Are you okay?"

"It's okay, I was just shocked." Ning Qingyun replied a little nervously. It is actually quite common to encounter such turbulence when flying, but before, I was sitting down, and this time I was still moving my hands and feet because I was standing.

Ning Qingyun was startled when she didn't stand firm.

Seeing that she was not injured, Qin Ke motioned to Wei Feng and others who had stood up to help him to sit down again, and he also sat down.

Professor Campbell almost lost his balance at first, but after Wei Feng helped him, he sat down smoothly.

Originally thinking that they were just encountering a small airflow, Qin Ke and Professor Campbell didn't care, and were about to continue chatting, but the next moment, the fuselage began to bump again, and it actually lasted for a while, and then the broadcast in the cabin started.

When it rang, the captain repeated nervously in Italian and English:

"Ladies and gentlemen, the plane is currently experiencing airflow and there will be some slight bumps. The restroom has been closed. Please return to your original position and fasten your seat belts. The flight attendants will stop serving meals, causing you inconvenience.

beg to be excused."

When the broadcast sounded, the huge fuselage jolted again, and this time the jolt was so large that even the paper and pens placed on the small table that had not been put away in time were shaken and fell down.

The most frightening thing was that the violent turbulence continued, and the half-drunk drinks fell over. The entire cabin was in chaos, and a series of exclamations were heard throughout the flight.

Because Ning Qingyun had just sat down and had not had time to fasten her seat belt again, she was almost thrown off her seat by the violent jolt.

Qin Ke reacted very quickly. He put his foot against the seat in front of him to steady himself, and quickly pulled the seat belt with both hands, trying to fasten the seat belt for Ning Qingyun, but the vibration of the fuselage was too violent, and he continued several times.

After failing to tie it on every time, he simply hugged Ning Qingyun into his arms and hugged her tightly with his arms. This was a completely subconscious action. Qin Ke only had one thought in his mind. No matter what,

Everyone must protect Ning Qingyun.

Wrapped in the familiar atmosphere, Ning Qingyun's original fear and nervousness were reduced by most. Just as she was about to smile sweetly, the plane shook violently again.

Screams and exclamations resounded throughout the cabin again, and many people had begun to cross themselves on their chests. Professor Campbell also looked a little pale, and he managed a smile and said: "I have flown dozens of flights to

The flight to Paris was a more thrilling one this time.”

Before Qin Ke could reply, the announcement in the cabin rang again: "Ladies and gentlemen, the plane will be bumpy when it encounters a strong mixed airflow, but please rest assured that everything is normal on the plane at the moment and it will be over soon.

In this crisis, please be sure to fasten your seat belts and hold on to the handrails..."

The captain's voice was a little more anxious, and everyone could tell that he didn't have much confidence in his words.

The plane's lights flickered slightly due to the violent vibrations. Ning Qingyun's face turned pale with fright, and she subconsciously hugged Qin Ke tightly, her little hands tightly interlocking with Qin Ke's left hand.

At this critical moment of life and death, her mind went blank, leaving only one thought. No matter what, whether she was going to hell or going to heaven, she must be with Qin Ke and never let go.

It was the first time Qin Ke encountered such a crisis, and his heart beat faster. But after hugging Ning Qingyun tightly, feeling the warm and fragrant soft jade in his arms, his mood miraculously calmed down. He comforted her with a gentle voice: "

Don’t worry, it’ll be fine.”

"Well, as long as you are here, I will not be afraid of anything no matter what I encounter. I...I will never leave your side, no matter where I go!" Ning Qingyun pressed her little face hard against Qin Ke's face

, the tone in the slightly trembling voice was unprecedentedly firm.

The soft blue hair slid across Qin Ke's cheeks and neck, bringing a pleasant scent like lime and a smooth touch, making Qin Ke feel even more how beautiful life is.

He took a deep breath, closed his eyes, and silently calculated the changes in the vibration frequency of the fuselage.

It is actually extremely dangerous for an airplane to experience turbulence when it encounters mixed airflow, because it is difficult to judge the extent of the impact of this airflow and where the wind is strongest. Once the airplane plunges into the strongest wind, it is likely to cause it to spin or even fall.

But all fluid mechanics, especially such high-altitude air flow, cannot escape the scope of n-s equation fluid mechanics.

Qin Ke closed his eyes and calculated the vibration frequency and amplitude of the aircraft with a mental arithmetic ability far beyond that of normal humans, and then substituted it into the variant of the n-s equation for calculation...

Wei Feng and Wei Jing had already squeezed over regardless of the bumps. They tied a small backpack on Qin Ke and Ning Qingyun respectively. Wei Feng said urgently: "This is an ejection parachute. If there is any danger, wait for the plane."

After falling to a certain height and the pressure difference between the cabin and the outside world is eliminated to the same level, we will find a way to open the emergency hatch, and you can jump out and open the parachute according to the method we have trained before..."

Qin Ke suddenly opened his eyes and smiled: "Don't worry, it will be fine soon. The plane is flying in the right direction and is away from the center of the mixed airflow. It will return to normal in about fifty seconds. We are lucky.

Otherwise, I have to think about how to convince the captain and pilot to change the flight direction."

Wei Feng and Wei Jing looked at each other, seeing that Qin Ke's words were conclusive and did not seem to be spoken casually to comfort others, but they still held on to the backrests of their seats tightly and stayed by Qin Ke and Ning Qingyun's side.

Qin Ke turned his head and noticed that Professor Campol next to him had sweat all over his forehead, his face was pale, and his lips were a little purple. He rubbed his heart vigorously, and hurriedly comforted him in English: "Professor Campol, don't worry.

It will take forty to fifty seconds to break out of this mixed airflow, just relax and don't be too nervous!"

He saw that there was something wrong with the blood supply to Professor Campol's heart. At this time, excessive stress and anxiety led to a sudden increase in systolic blood pressure and myocardial ischemia. If he could not relax, he was afraid that it would lead to myocardial infarction, and the consequences would be disastrous.

Professor Campol reluctantly opened his eyes and looked at Qin Ke. Qin Ke said firmly: "Professor Campol, listen to my countdown and breathe. When my countdown is over, this difficult time will be over. You must

Hold on...47...46..."

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Professor Campol's heart felt very uncomfortable. He didn't quite believe what Qin Ke said, but he could only try to abandon distracting thoughts and relax, pressing Qin Ke's

Count down and breathe in and out rhythmically.

Something magical happened. During Qin Ke's countdown, the violent turbulence quickly stopped, leaving only slight turbulence. When Qin Ke's countdown almost reached 0, the plane completely returned to normal navigation.

Everyone in the cabin was in shock, not knowing whether they had completely overcome the danger.

At this time, the broadcast on the plane sounded again, and the captain said in an obviously relieved voice: "Ladies and gentlemen, the plane has successfully passed through the mixed airflow. Please don't panic. The flight attendants will be here soon to serve you. If

If anyone was injured in the bumpy ride just now, please contact our flight attendants in time, and we will provide all kinds of medical services within our capabilities..."

Only then did Wei Feng and Wei Jing wipe the cold sweat from their foreheads, and looked at Qin Ke with a bit more incredulity, as if they were looking at a magic stick...oh no, a god.

Qin Ke actually predicted the flight conditions of the plane while sitting on the flight. This can no longer be explained by common sense.
