The days of learning black magic in another world

Apart from Riemann, none of Iserveld's family dinners were satisfactory.

Elaine Iserveld is a person who can't hold back her harsh words. Even Mrs. Frenner's warning is enough for her to shut up and eat for 10 minutes-the real chewing time in these 10 minutes is even only For 1 minute, everything else was spent playing with knives and forks angrily.

However, due to her blessing, Riemann barely extracted the reason why this family did not welcome him so much from her non-stop BB.

From their point of view, if Riemann really wants to take the surname of Iserveld, then as the eldest son, he has the right to be the first in line of succession, good guy, look at the comparison between him and Little Albert—— Greedy (willing to work for other nobles for a little money), ignorant (knows nothing about high society, not even Dengdengguo), rude (table manners are not even as good as six-year-old Phil), if Iserveld really has With such an heir, he will become the laughing stock of the whole king city!How can this be!

And hasn't he spent the past ten years in the slums?Who knows what strange disease he has contracted, and he is so greedy for money, if he really gets the wealth of the Iserveld family, he may lose his family property in minutes!It's really scary to think about it.

As for the only advantage, it may be that he is a student of Springs College, but the real famous one among Springs students has to be the one who became famous early on like Master Peg of the Chester family. Geniuses, ordinary students like Riemann, are mostly unknown all their lives.

In short, Marianne and Bernard, the eldest son of Iserveld who came out of nowhere, can find him a house outside if they want, and call him over occasionally to share the family happiness. It is absolutely impossible to recognize him as the nominal eldest son and heir of Iserveld.

Fortunately, Marianne was the only one who lost his head. Bernard obviously didn't like this son who appeared out of nowhere very much.

Riemann just wanted to express this-do you have the primogeniture system here?

He was in no hurry to say—I just wanted to join the family, not to claim the inheritance—but he finished the meal in peace, and made an appointment with Mrs. Marianne to come back next Sunday.

At the same time, Wangcheng's department in charge of publishing publications ushered in a new issue of "Mathematics".

The clerk behind the ebony desk raised his eyes, took the "Mathematics" handed over by the other party, and sneered: "Why bother, we in Sidney really have no shortage of mathematics publications, and the mathematics papers of Ulang people are read by our Sidney scholars. It’s almost like a child’s play house, why do you bother to spend this money and sell it to Sydney at a loss?”

"Oh, who knows? It's useless for you to tell me. I'm just an errand runner. I don't know what those noble gentlemen are thinking. Let's go and drink."

"That's right, I've been in Ulang for a long time, and my IQ has been assimilated by the Ulang people. How could I ask such a question to a child who doesn't know anything..."

Although he didn't think much of Wulang's mathematics journal, it was his job after all, so he still sealed this issue and sent it to Sidney.

……

Sidney, the capital of the kingdom.

The streets of Sydney King’s Capital have always been lively, and the most exotic gadgets in the whole continent are concentrated here. Most of the tourists or locals walking on the street are full of smiles, so the sad-faced young man in the crowd is even more so. conspicuous.

Louis Jerome is a graduating student at Donick College - but he thinks he probably won't be able to graduate... this year's dissertation is reviewed by Professor Ram - God, how can he be so unlucky, why Catch up with Professor Ram!

In the entire Donic College, there is no professor who is stricter than Professor Ram, who is critical of students' papers!

If it was another professor, he might still be able to get away with using the old method to solve new problems, but if it was Professor Lahm... this path would definitely not work.

So, on this sad morning, he stepped out of his warm dormitory to seek inspiration. He walked to the place where newspapers were sold and said to his boss, "Boss, here's a copy of the latest "Frontiers of Mathematics at Sidney."

"Okay, 1 silver coin."

"What?! "Frontiers of Mathematics at Sidney" only costs half a silver coin?!"

"The price has been raised a long time ago, my husband. It was raised to this price three months ago."

Louis' face flushed suddenly, indeed... he was very lazy some time ago, and others stayed at home to study the topic of graduation thesis, but he was the only one who went on vacation. He didn't know that the price increase of "Sydney Frontiers of Mathematics" was also caused by him. It's his own fault... Well, if he worked hard, would he still be in such trouble now?

"Why don't you get a copy of Wulang's "Mathematics and Physics", it only costs two hundred copper coins!"

Louis subconsciously wanted to refuse.

That place in Ulan is nothing more barbaric. Its art and culture are very backward. The only mathematician that Sidney recognized was Achill Monroe, and that was decades ago. , now Archel Munrod is 60 or [-] years old, and it has been a long time since he published a new noteworthy theory.

But... Alas, Louis sighed, and he came out with five hundred copper coins, and he didn't want to go back empty-handed, and to be honest, he's been a little tight lately, and the vacation for the first two months was really extravagant and extravagant, which led to His parents stopped him from spending...

"Then get a copy of Wu Lang's Mathematics..."

The boss, who thought that this issue of "Mathematics and Physics" would still accumulate dust as usual, was overjoyed, and happily took out a copy of "Mathematics and Physics" and handed it to the wronged guest.

Louis Jerome went out with a sigh, and returned to the dormitory dejectedly.

After arriving at the dormitory, he first ate some snacks, read the books he hadn't finished last semester, and finally enjoyed the scenery outside the window. Finally, he sat down at the desk and opened the book "Mathematics and Physics"—— Yes, I bought everything, let’s take a look, although there may be mentally handicapped articles like "the sum of the interior angles of a triangle is equal to 180 degrees".

With one last dessert in his mouth, Louis wiped his hands on a handkerchief and slowly opened the magazine.

Then his brow never opened again.

What he has to admit is that before he opened this magazine, his attitude was arrogant and scrutinizing. The top students need to be strong.

But as soon as he opened this magazine, he couldn't help but start to wonder if he had been studying for nothing in the past few years...

The first paper he saw was quite simple at the beginning. It talked about a method of rooting. Although it was cumbersome, it was indeed quite effective, but it was of a citation nature. After the citation, the author changed his style—— This is evident" The next line of the sentence gives a long list of formulas.

Louis almost scratches his head—"obviously"? ? ?Where is this apparently? !

Louis took out the paper in the drawer, and began to push it backwards resignedly, to confirm that the author did not give the wrong formula.

However, his scratching journey has only just begun.

The author gave a general description of the meaning of this formula, then changed his style of writing again, and gave a definition called "infinite series" under the sentence "it is obvious from this" that appeared again.

Louis: ? ? ?

Why? ?Why would you think of defining a thing like this? ?Can you share your thoughts in the article? !

These days, although papers do not need to count words, people who write papers generally like to brag about their ideas, so the process given is very detailed. This is the first time Louis saw someone crazy use the word "obviously visible" in a paper. Words say something totally unobvious!

But the definition of infinite series is not the thing that bothers him the most. After writing two relatively simple content to pave the way, the author finally began to output his own horrible ideas like crazy.

"...From this we can see that a definite sum can be obtained after adding some infinite series, we call such an infinite series convergent..."

"The simplest example would be:..."

"Then let's go back to the binomial theorem just now, and extend m/n to the range of rational numbers..."

Louis Jerome snapped the magazine shut—he thought he'd have to slow down or his brain would explode.

how is this possible? !how is this possible? !

How can the sum of infinite numbers be equal to a fixed value? !

Oh... The example the author gave at the beginning is relatively easy to understand. As long as the total number is an even number, -1 and 1 can be added to each other, but the example he gave later... how could the sum of those numbers be What about a fixed value?

Louis felt that his world view had been subverted...

He was thinking so hard that his head was about to explode, and finally he resigned to his fate and opened the magazine to continue reading. Let's follow the author's train of thought and verify his calculations, it's better than thinking of knotting his own brain...

At this time, the author suddenly became considerate, and did not give them all "obviously visible", and the derivation process was quite detailed, as if to make the most stupid people verify his conclusion step by step, it is completely a fool-level operation Tutorial is up.

So, Louis followed this fool-level tutorial to calculate step by step, took a deep breath, and could actually come up with a fixed value...

Oh, God of Light, mathematics is really not suitable for a fool like him, he should stop thinking about graduation, just pack up and go home...

"And there should be many more series like this. I hope readers here can find out more."

and many more.

Desperate Louis Jerome saw the last sentence of this article...wait, his graduation thesis seems to be saved?
