The days of learning black magic in another world

Riemann is very happy, the kind that is sincere.

The speed at which he turned the manuscript paper gradually became faster, and sometimes slower, occasionally frowning, chanting intermittently, and then he was obviously completely immersed in it, with a face full of "I am in my own world, don't disturb me".But his overall expression is still very happy, and it is joy from the heart, and there are lights on his face and eyes.

Professor Housman's expression was a little strange, which was not the reaction he expected.

To be honest, he has complicated feelings towards Riemann, some are admiration and jealousy, but more because he wants to give him some color after the other party rejects Donic’s invitation, and let this ignorant kid know that there is nothing in this world More than a genius mood for him.

So he studied Riemann's papers more seriously than anyone else, and unlike most fools, their ideas were completely taken away by Riemann Iserveld. Whatever he wrote, they swarmed to think What - unlike these idiots, he wants to write some articles that really make this kid realize that he still has shortcomings.

So this is what he did.

He is proficient in geometry, and would think that Riemann only focused on the area of ​​geometric figures in all his past articles (and only the area of ​​some geometric figures. He can only find the area of ​​those patterns whose sides are curves. He I realized this when Riemann deduced the area formula of the circle. The other party divided the circle into four pieces and only calculated the integral in a certain quadrant. It is a very clever approach, but it is also very tricky) rather than volume. Granted, in fact, once he thought about it, he couldn't help wondering why no one else saw the obvious.

So he spent a lot of time thinking, is there any way to use Riemann's integral to find the volume of geometry?By the way, is there any way to find the area of ​​a geometric pattern in a more general sense?For example, if you think like a fool, if a fool wants to derive the area formula of a circle, then he would not think of dividing the circle into four like Riemann, would he?What if the idiot just wants to find the area of ​​the whole fucking circle?

After dozens of sleepless nights, Housman found a solution.

He was going to publish this scary article in the "Preface to Sidney Mathematics", which will be released in a few days. In countless sleepless nights, he wanted to see this article hit Riemann in the face like a punch Such thoughts supported him to yell "Why is it wrong here!", then took a deep breath and continued to work.

When the essay was finally over, he almost laughed out loud—in fact, “almost” might not be the right word, he did, and he seemed to be able to see Riemann Iserveld had a shocked expression on his face—although he still didn't know what Riemann Iserveld looked like.

But what he didn't expect was that things were more satisfactory than what he wanted to advance, and Iserveld actually came to the capital.

Very good, imagining a heavy blow is not as good as seeing it in person.

However, he never thought that the other party's reaction would be like this.

Hey!Shocked?Puzzled?What about yelling?Or even if you didn't yell, you at least put on a distraught face?You are so happy, what do you want to do with such an innocent happy expression!

Professor Hausman felt as if he had already entered the duel ring, and he made a wonderful blow. As a result, the opponent not only did not fall to the ground, but laughed brightly—"Good sword!"

He didn't know that Riemann was really happy - his original plan was to start by himself, and then let other mathematicians in the world complete the rest of the calculus. He didn't expect that someone would complete his calculus so quickly. What you want them to accomplish! !It is still the most troublesome and trivial part of re-integration!

God!He looked at the tall and fat professor kindly. Why did he feel hostile to him just now? !This is obviously a child who can't wait to share his achievements with others!Yes, in his filter, this 40-year-old professor who is among the best in height and weight in another world has become an image of a primary school student who is asking for praise after he solves a difficult problem.

Riemann felt that he understood. It turned out that the other party didn't come to find fault. It was only because he couldn't find anyone who could understand his genius idea that he let him appreciate his achievements after knowing that he was in the capital. As for what he just felt Tensions—well, mathematicians, aren't social skills almost normal?

Riemann, who deeply felt that he understood and had great responsibilities, sincerely praised the other party: "Professor Hausmann, you are really amazing!"

Hausmann was not happy, he did not miss Riemann just blurted out the sentence "You got the heavy points!".

This means that the other party not only already has this idea, but also gave this expansion a name-to be honest, it is quite suitable to focus on points.

"Oh, look at this wonderful idea!" Riemann happily pointed to one of the manuscript papers and began to chatter and praise, "This transformation is really wonderful. If it were me, I would definitely do a lot of calculations stupidly. .”

No you won't.Professor Hausman muttered dissatisfiedly in his heart, you even have to convert the derivation formula of the area of ​​a circle into an ordinary integral.

But... Well, the idea you pointed out is really brilliant, and he couldn't help but praise his genius when he came up with it himself.

"Look here! And here! Here..."

Riemann perfectly played the image of Bole, exaggerating all the praiseworthy content in the other party's article.

Well, Professor Housman reluctantly admits, he was quite happy.

This guy Iserveld...isn't he very arrogant. It seems that his rejection of Donic Academy was not out of arrogance, but simply because he wanted to serve God.

Hmph, it's okay, it seems that he should urge the other party not to indulge in those useless classics, and spend more time on mathematics to serve God better.

"Oh, by the way, I haven't asked you yet, Professor, what is the purpose of your visit?"

Housman froze when he saw the sincerity of Riemann's face. After a while, he had a flash of inspiration and found a suitable reason.

"I found out from the newspaper that you are in the capital. It is a waste of your talents for you to do those trivial things. From today onwards, you will come to Donic College to teach those idiot students during your entrusted time."

Riemann's eyes lit up.

That's okay too!Taking classes is better than being a mediator!

……

"Huh? Riemann Iserveld is teaching in the academy? He is in the capital? Who invited him?"

In a simple office, a beauty with slightly curly hair is leaning on her chair. She has a lazy temperament, as if the only thing she has to do every day is to become a beautiful picture scroll on the recliner among the sea of ​​flowers. But as soon as she opened her mouth, the aura disappeared.

Her voice was not only ice-cold, but she also spoke extremely fast. The continuous questions came down like a hailstorm, making people feel like they were in a snowfield.

"Professor Ram, Mr. Iserveld was invited by Professor Hausmann. As for why Mr. Iserveld is in the capital—he received an internship invitation from the Church of the Royal Capital, so he will stay here for a month."

"Hausman?" Professor Ram frowned.

Housman... As Housman's old enemy, Lahm can be said to be one of the people who understand him best in the world, and from what Lahm knows about him, Housman is not the kind of broad-minded person, more He is not someone who thinks about his students. This kind of invitation to reject Donick's up-and-coming star to teach his students is not like what he can do...

Wait...she got it!

She knew that Housman had been suspicious recently. Although he had a bad temper, recently even his favorite students couldn't enter his office. From what Ram knew about him, he must be Do what he thinks is very important research.

To be honest, Lahm hasn't seen Housman in this state for a long time. After all...he is in his forties, and his thinking has gradually become dull. In recent years, he has been living on his laurels.

And his state started from the few papers published by Riemann Iserveld.

Of course, Iserveld's theory of calculus, of course, what else?

After all, she herself has been inspired a lot of ideas, even if Housman's brain is rusted into tatters, it will not be completely unable to turn.

So...he must have finished something, and then went to Iserveld...

But what did he do with Iserveld...

Hell, she knew it!

The old fox!

He must have completed something, but he didn't want to be singled out for any mistakes, so who better than Riemann Iserveld to help him proofread the final draft!

old fox!What an old fox!

Ram opened the drawer, and there was a stack of manuscript paper inside. She squinted her eyes: "When Mr. Iserveld finishes his class, please help me to ask him to come over?"

"I see, Professor Ram."

……

Riemann scheduled the end of get out of class at 10:[-]. As for why, of course, it was because it would take [-] minutes to go back to church.

What is time management...

But just as he had time to go out the door, he was stopped by someone.

"How do you do, Mister Iserveld?"

"It's me, are you?"

"Professor Ram invites you to talk."

Professor Ram?Who is this?Riemann lamented in his heart, he really didn't know any of the people from Donic Academy...

But he still kept pace with the opponent.

Professor Lahm's taste is obviously much better than that of Hausman. It is not a blind tyrant who decorated it in a low-key and luxurious way, and Professor Lahm himself is obviously more aesthetically pleasing than Professor Hausman.

"Hello, Mr. Iserveld, I take the liberty of inviting you here, and I hope I won't delay you."

Riemann shrugged: "If you mean looking at the sun bricks idly in the corner of the church, then I was really delayed."

"Hahaha, I didn't expect Mr. Iserveld to have such a sense of humor. Looking at your paper, I thought you would be a more rigorous and rigid type."

"Thank you, so what's the matter with Professor Lahm looking for me?"

"Oh yes, I have a paper about to be published and I want you to see it."

As he said that, the other party handed over a stack of huge manuscript paper, and Riemann turned a few pages curiously—"Huh? Ordinary differential equation?!"
