Marvel's Spider-Man: Web of Destiny

In the morning at the Paris Academy of Sciences, the spring sunshine passes through the classical-style window lattice, casting mottled light and shadow on the polished marble floor, like an oil painting with a golden frame.

Outside the window, the ancient plane trees swayed gently in the breeze, and the new green leaves complemented the blue sky, adding a bit of vitality and tranquility to this temple of knowledge.

On the tree-lined path under the plane trees, two French gentlemen were walking together.

They were not moving very fast, and their steps were neither fast nor slow. Accompanied by the rustle of leaves being blown by the breeze, you could occasionally hear their chatter and laughter.

The slightly younger gentleman looks to be in his early forties. He has thin and strong cheeks, a high nose, and a pair of deep blue eyes in his eye sockets. Wearing a black silk top hat, with meticulously combed silver-gray hair exposed under the brim, he is wearing a dark blue double-breasted swallowtail coat, which is thick in texture and well-tailored. A dark silk tie is tied around his neck, making it even more... Highlight his scholarly demeanor. Wear a white high-collar shirt underneath, and the delicate lace trim at the cuffs reveals his attention to detail.

As for the older gentleman, he simply wore a black woolen robe. The wide cuffs and loose hem swayed gently in the wind, showing his calm and calm academic temperament.

I thought that the study of Euler's equation would end here, but what I didn't expect was that one day a few months later, Cauchy suddenly walked into my office with a stack of paper. He said that he introduced the concept of stress tensor of fluid particles into the Euler equation under the prerequisites I gave, and then he found a set of formulas in a daze, and he could accurately reflect the fluid motion through this set of formulas. Differences from solid motion.

Navi nodded slightly and said: "For the same mistake, making it once is a mistake, but making it twice is stupid. Although I can't be called a smart person, I don't want to be regarded as a fool by others, so of course I have to learn a lesson. After all, I I still have a teaching position at the National Road and Bridge School. Although I may not have the opportunity to lead bridge design again, at least I can’t let the students make the same mistake I did.”

He turned sideways to get out of the way and watched Liouville take Arthur away. Just as he was about to enter, he heard Navi say: "Is that young man the new assistant coach?"

I had just finished this work, and the next day I excitedly showed my latest research results to Cauchy. He happened to be very interested in this aspect, and he could see the shortcomings of the formula at a glance. ——This is just a set of equations describing the dynamic equilibrium and motion of incompressible fluids. It is obviously not enough to describe the laws of fluid motion at the macroscopic level. I am also aware of this flaw, but with my ability, deriving it to this point is already the limit.

"This can be considered a good thing. After all, if he uses his brain so much to write papers, his body can't sustain it for too long. You don't know that when he was young, writing papers was like a printing press, because The papers he wrote were so numerous and thick that he almost took up all the pages of the journal, so the Academy of Sciences passed a special resolution stipulating that the length of each published paper should not exceed 4 pages. He could take a break. Rest, it’s a good thing for those young scholars who are eager to show themselves on the stage.”

Coriolis shrugged and said, "Probably. Are there any outsiders in the Academy of Sciences? Even if there are, they are some officials, but as we all know, officials will not come to the library."

The two chatted and laughed along the way, and soon followed the tree-lined path to the door of the library.

As soon as Navig entered the door, he went straight to the bookshelf at the back. He remembered which book he seemed to have stuffed the calculation paper into.

Having said this, Navi suddenly stopped and asked: "Speaking of which, why are you suddenly free to come to the Academy of Sciences today? Today is neither Wednesday nor Saturday. There should be no meetings to be held in the Mechanics Department? Could it be that you are What’s new?”

Gustave Coriolis, a backbone scholar in the French scientific community who studied under Augustin-Louis Cauchy, a member of the Department of Mechanics of the French Academy of Sciences, a former professor of geometric analysis and general physics at the Ecole Centrale Supérieure des Beaux-Arts, and currently a professor at the Ecole Nationale des Beaux-Arts in France. Professor of Applied Physics.

On the calculation paper that should have contained only his personal derivation process, there were surprisingly three more derivation equations, and at the top of each equation, their scope of application was thoughtfully noted.

Navier also recognizes the second one, because it is a system of equations derived by Poisson.

Coriolis walked towards the chair that was still cold. As soon as he got closer, he discovered the calculation paper on the oak table filled with calculations and derivation processes.

Coriolis shook his head and said: "No, he went to Graz with the Bourbon royal family a while ago. Metternich of the Austrian Empire ordered all the orthodox dynasty exiles in the country to be moved there."

"He should have done less recently, at least not as crazy as when he was in Paris. He now devotes most of his attention to educating the Duke of Bordeaux."

For most people at the Paris Academy of Sciences, just two simple surnames are enough to understand the outstanding academic abilities and professional experience of these two gentlemen.

Navi frowned and thought for a while after hearing this: "Introducing a brand new force? This idea is indeed bold, but until it is completely falsified, I can't say that this idea is wrong. Well...you find this Do you know the mathematical expression of force?”

"Being respectful is worse than obeying orders."

Seeing this, Arthur also said good morning: "Good morning, gentlemen."

"morning."

Judging from real experience, pressure does not significantly affect the resistance generated by the molecular interaction between various parts of the moving fluid, and these resistances are more derived from the speed or direction differences of adjacent molecules. Therefore, based on this premise, I further derived a classified expression of the force exerted on molecules by the motion of adjacent molecules based on the Euler equation.

Navier just wanted to open the library door, but found that the door opened by itself from the inside.

When Coriolis heard this, he couldn't help laughing and said: "You are right. Mr. Cauchy's temporary departure is a misfortune for the entire French scientific community, but it is a blessing for all French scientists. When he was at the Academy of Sciences, he was simply Like the Alps, the only one who can be indifferent to him is a genius of the same level as Mr. Poisson."

After all, at the French Academy, teaching assistants come in and out every day, and there is nothing unusual about new people coming and going.

Claude-Louis Navit, a disciple who inherited the legacy of his mentor Jean-Baptiste Joseph Fourier, is an academician of the French Academy of Sciences, a former member of the High Commission for Bridge Construction of the Paris High Court, and is currently a calculus and mechanics professor at the Ecole Polytechnique in Paris. Professor and Professor of Mechanics at the National Institute of Roads and Bridges in France.

"Well, that library is too remote, so few people go there. But like me, Amp, and Kesi, we all like quiet places, so we all want to get together there. What do you think?"

Coriolis also smiled and said: "Me too, I think mechanics is more interesting than electromagnetism. Electromagnetic induction is certainly magical, but I am obviously more interested in the equation of fluid motion you just mentioned."

Almost every highly educated guy will be in awe in front of these two gentlemen, but unlike the collision of ideas that everyone imagines between academic masters, the two of them are not always happy when they are together. Discuss some academic issues.
