The days of learning black magic in another world

Riemann quickly remembered who this Professor Ram was.

He read the book written by the other party in Bartley's library. Unlike most people who are obsessed with geometry, the other party is a relatively rare algebra expert, and his writing style is very unique, so Riemann just read a few pages. A beautiful professor with dark brown hair was connected with the cold name "Riya Ram" on the page.

At the same time, just like Professor Hausmann, Professor Lahm keenly grasped the word "ordinary differential equation" that Riemann blurted out.

"Have you thought about it?"

She asked almost eagerly.

Riemann froze for a moment, and quickly waved his hand: "No... no, no, please don't have any misunderstandings that I want to compete with you for the opportunity to publish this paper. I just have a picture in my brain... but it is only picture."

—He really didn't want to!

Professor Ram quickly noticed another point: "Why do you say ordinary differential equations? What do you mean by ordinary, uh, I mean, this is indeed an equation with differentials, yes, I was going to call it that, but Why do you want to add a regular?"

Riemann: ...

Why the hell?Of course it's because he's used to it...

He should have known—bad words come from his mouth.

But it's nothing, it's not a big problem, just to inspire the other party, if this Professor Lahm can come up with a partial differential equation by the way, it will really help him a lot.

"Well, it's just me thinking about the general picture of calculus. Of course, I take it for granted that equations are divided into single-variable equations and multiple-variable equations. In the solution of single-variable equations, that is, you are studying These always have, uh, you know, constants, so..."

"Multiple variables...multiple variables! You are right! Multiple variables! How did I not think of that?! Oh my God, Mr. Iserveld, I am so glad I have you today, otherwise I would have put This incomplete article has been sent!"

Riemann: "?"

Riemann: "No, no, I think this is quite complete! Although they are all differential equations, there is no need to cram them into an article!"

After all, they learned these two equations as two different courses at the beginning...

"Of course!" Professor Lahm glanced at Riemann in amazement, "If I sent this article directly, only a fool would not think of it—hell, of course there are multiple variables!"

Professor Lahm was obviously too excited, and he didn't care about calling himself a fool just now.

Out of respect for the genius mathematician, Riemann did not refute again, but sighed in his heart-when will this have to wait?

Professor Lahm thanked Riemann one last time, oh no, twice (maybe three times?) Riemann, and then saw off the guests—she had to start working.

……

The next day, Donick Academy.

"Hey! What are you doing so fast?"

"Don't you know? Riemann Iserveld is in class in the auditorium!"

"What? What? Why is he here? Oh! I see, he finally decided to accept Donick's position, right?"

"Uh, that's not the case, it's actually because he's an intern at King's Church, and then Professor Housman invited him to teach his students, so strictly speaking, we're taking advantage of Professor Housman now... ..."

"Wow! Why don't you go now?!"

The two students who ran into each other on the road successfully reached an agreement, and they rushed to the auditorium together.

When they got to the auditorium, they realized that they were not the fastest runners.

The auditorium is almost full of people——the word "crowded" may not be very accurate, after all, Donic College is not the kind of college with many students, but they have indeed lost the qualification to sit down, so They can now choose to stand and listen to the lecture or leave now.

The couple next to them was thinking about it too.

"To be honest, we don't know the level of Iserveld's lectures... After all, uh, given the performance of Professor Hausmann and Professor Ram, I think we have basically figured out the degree of human genius and his lectures The level is inversely proportional to this conclusion."

"Hmm... so, let's listen for a few minutes first? If you don't understand, leave?"

"agree."

Riemann Iserveld came very punctually (of course he was punctual, he was not willing to take any risk of becoming a neighborhood committee again), he was obviously taken aback when he walked into the auditorium, he probably did not expect that there would be so many people— —If only Professor Housman's students came to the class yesterday, today's number should be regarded as a terrifying increase. After all, Professor Housman is very picky and has very few students.

But he soon laughed with a good temper, and his voice was also very gentle—at least much gentler than the cold Professor Ram and the sharp Professor Housman.

"I didn't expect there to be so many people, so I'll start from the beginning and talk about yesterday's content. Students who have heard it can use it as a review."

The newcomers in the audience were moved to tears—they had never seen a professor who took care of the students so much!

The sitting students of Professor Housman, who had heard it once yesterday, also burst into tears -- that's great!To be honest, when they listened to it yesterday, they really felt that they understood it!And I understand it very well!I have never understood calculus so smoothly in this life, but...it is very sad that when they returned to the dormitory with such a passionate mood, they were about to start writing, but found...that they didn't seem to understand it very well.

Moreover, because it feels so good to understand everything during the lectures... great, they didn't take a lot of notes, so they couldn't review it if they wanted to.

On this basis, they dare not tell Professor Hausmann or Mr. Riemann this, which makes them even more depressed.

So great!Mr. Riemann decided to speak for the second time!This is really - great!

Riemann was good at lecturing, which isn't too surprising considering that he taught advanced mathematics for a living to people of all abilities, and spent a lot of time thinking about how to make them understand.

But for the students of Donic Academy, it was an absolute surprise.

These days, there is no such thing as pedagogy. It is good enough that teachers are willing to share their knowledge. As for the way of sharing knowledge—who cares?You're not smart enough to understand what I'm saying and what does it matter to me?

Everyone thinks so, so a good teacher like Riemann who is "21st century standard" is like an angel shining with holy light at this moment, making people blind-tearful.

After Riemann left, everyone was still immersed in this wonderful class experience.

So, even though there was really no place to sit in the auditorium, they still showed up here at [-]:[-] the next day.

However, it didn't take long for them to learn with heartbreak that Mr. Riemann would not be able to come to class today.

It took a while for the heartbroken students to think about a question-"What is the reason why Riemann failed to come to class?"

"Wait a minute... Do you think that the person who came to announce this just now looks familiar, or strange?"

"Yes, he is not Professor Housman's valet."

"Oh my God—he's Harvey's valet!"

Harvey, because the surname is the same as the Queen, so just like everyone calls Leina "Miss Leina", no one will directly call Harvey, the royal family's surname.

"Damn! Harvey has been tortured by Professor Ram recently because of his graduation thesis. He must be looking for Mr. Riemann to give him a little trouble!!"

"Hiss—too cunning!"

"Hey! He's just the grandson of the queen's uncle, and his title is only viscount. I'm an earl anyway! Since he can invite Mr. Riemann to private classes, why can't I?!"

"Hey! Mulhouse! Harvey has broken the rules. You can't be like him. If everyone does like you two, everyone will miss the class!"

"Well, you have a point...I'm a moral person, and I'm not like Harvey."

"..."

"Mulhouse, do you think I, as your brother-in-law's younger brother, can come to attend classes together?"

……

The invitations that Riemann was looking forward to came a little later, but they still rushed to them.

(Professor Hausmann lifted the ban on inviting Riemann to others after getting the result that was not what he wanted but was still satisfactory)

But...he wasn't quite sure this was the result he wanted.

Uh, he meant that the invitation he originally imagined was probably "Hey Mr. Riemann, let's have brunch and chat by the way, don't need to talk about any advanced content, as long as I go out, I can say that I chatted with you Something math-related would do" - or so.

But the current result... It can't be said that it has nothing to do with his imagination. He is indeed inviting people to chat about "mathematics-related things", but he is not just chatting nonsense, but is really serious. Talk about math.

He had to admit that the students of Donic College were really curious and motivated. He was first invited to the home of a student who was obviously more prominent to give his opinions on his graduation thesis, and then he was invited to another student who was obviously more famous. The prominent student answered the questions that the other party had accumulated since the paper he published on series—hell, the other party took out a small notebook directly.

And now, once again, he was booked before leaving for class.

It's not that he has any dissatisfaction... Although the current situation is indeed different from his imagination - "eating and chatting easily" - it is definitely better than completing all kinds of magical commissions.

Thinking of this, Riemann sighed secretly, picked up the hem of his robe and stepped into the carriage.

After he sat down, a thought suddenly flashed in his mind - this carriage... seems familiar?
