Chapter 7 In Front of Zhen Xueba, All Mortals Are Scum

In the end, reason prevailed over greed, and Lu Zhou dismissed this unrealistic idea.

It's nothing for a freshman to publish SCI. Anyway, the phenomenon of irrigation in domestic mathematics SCI journals is quite serious. As long as your English skills are OK and irrigation is like that, you may pass.

This phenomenon of overcharging has led to a certain good person making a ranking list for several well-known irrigation journals in China. At the top of the list, Applied-Mathematics & Computation (AMC), is well-known in the field of irrigation.

Speaking of Shanghai University alone, in just four years, hundreds of mathematical papers have been published on AMC, and some irrigators have written more than 20 papers a year, which is not a problem at all!

In order to ensure the academic quality of papers, those well-established journals often strictly control the number of papers published in a year to less than 100. But this "big mac journal" is very skinny, publishing more than 1,000 papers a year, plus cross-citations and other phenomena, the impact factor jumps up! Even due to the existence of a large number of pseudo-reviews, a certain editorial board posted more than 100 articles on it!

Other SCI journals Lu Zhou may not have confidence, but AMC's words...

Say he is confident or say he is swollen.

In short, Lu Zhou felt that the problem was not a big deal.

However, if the proof method of Zhou's conjecture is published in the SCI journal, the problem will be big. It's not a question of whether or not to pass. Passing is definitely possible, but the key is whether he can hold it after passing.

In the end, although Lu Zhou still chose the third task, he didn't plan to use Zhou's conjecture to prove it, but just wrote an irrigation paper to pass the task.

With his current understanding of the two courses of advanced mathematics and mathematical analysis, he is no less than that of graduate students. Coupled with the level of English at the fourth level, the distance from writing an English paper is only some professional terms, and these can be solved by looking up a dictionary.

On the other hand, in the other two tasks, in the first one, he didn't have that kind of connections, and he didn't think he had such a high emotional intelligence.

The second one, I haven't even started the course of big things in my freshman year. I'm afraid that the system brushes out all high school physics exercises. The ghost knows how much the difficulty factor is determined. And the physics level is not so attractive to him. The name is only used in the later stage, and it is not too late to practice when needed.

After choosing the task, Lu Zhou patted the grass clippings on his butt, stood up, and walked towards the dormitory while humming a song.

After being outside for so long, if I don't go back, I'm afraid Liu Ruide will be mentally ill.

This kid is very strange, although he is usually generous, but in terms of learning, he is so careful that he is speechless. A glance at your notes can chase you two streets, and asking a question can throw you a dozen or so eyes, probably talking about this type of person. In his eyes, the whole world seems to be his competitors, and what he is chasing is probably not any academic level, but only the first in the eyes of teachers or classmates, or the status called "Student Master".

Is this kind of person a scholar?

Lu Zhou doesn't think so.

In the eyes of Zhen Xueba, all mortals are scum, so what if I showed you my notes? Zhou Shi guessed you would? In front of you, you don't even understand!

In Lu Zhou's cognition, there seems to be only one person who meets the condition of being a scholar.

Well, that's right.

No doubt, he was talking about himself.

...

Pushing open the bedroom door, no more, no less, exactly ten o'clock.

Liu Rui was holding the exercise book and brushing the questions. The other two were not in the dormitory, they were probably playing cards next door. Shi Shang is a person who usually listens to lectures and doesn't particularly take time to review at the end of the term. As for Huang Guangming, he is probably the legendary god of learning. He usually doesn't listen to lectures.

Throwing the backpack on the table, Lu Zhou reached into the drawer to find his bath card.

At this time, Liu Rui put down the exercise book in his hand and glanced at Lu Zhou's direction.

"Elbow, are you working so hard?"

"I have to work hard. I haven't touched a book for almost half a semester. If I don't work hard, it will be too late." Throwing the bath towel on his shoulders, Lu Zhou stood up from his chair.

Seeing that Lu Zhou was going to take a bath, Liu Rui suddenly said, "I have a problem here that I can't solve, can you help me check it?"

Yo, that's weird.

Are there any questions you can't solve?

"Come and see."

Lu Zhou stretched out his hand, Liu Rui pushed on his glasses, handed over the exercise booklet in his hand, pointed to the circled topic and said, "That's it."

"The question of points? This thing shouldn't be difficult, right..." He glanced at the question and was surprised by the question type he had never seen before. Lu Zhou was interested, so he was not in a hurry to take a shower, and sat back down with the exercise book. He sat on the chair, picked up the pen and began to write and draw on the scratch paper.

If before, if he could stumped Liu Rui's question, he would definitely not be able to solve it. But for some reason, there was no "impossible" thought in his mind at this moment.

Seeing Lu Zhou count with a pen for a while, Liu Rui breathed a sigh of relief, secretly despising the sentence that a scumbag is still a scumbag, no matter how pretentious he is, he is still a scumbag.

Regarding this question, it is true that he cannot solve it, but there is actually a reference answer, and there is a detailed solution on the answer. The reason why I asked Lu Zhou this question was not because I was humbly asking for advice, but just to "spy on the enemy's situation".

Taking 10,000 steps back, even if he wanted to ask a math problem, he wouldn't look for a student like Lu Zhou.

Thinking like this, Liu Rui said, "How about you copy the question down and do it? Let me think about the next question first?"

The hidden meaning is that you can't write well anyway, so I won't waste your time.

However, Lu Zhou's reaction was beyond Liu Rui's expectations.

"...No need, untie it."

solution, solution? !

Liu Rui's eyes widened, his eyes bulging out in surprise.

"Well, you heard that right." Turning the ballpoint pen in his hand, Lu Zhou explained to the formula on the scratch paper, "It is a typical double integral problem. The first step is to convert the rectangular coordinates into polar coordinates to start the calculation. , due to the interval symmetry, this part of the formula can be simplified to cotx after calculation..."

"Finally turn it into an integral of cscx! Then substitute it into the original function!" Liu Rui's pupils shrank slightly, keenly seeing through the core idea of ​​this solution. difficulty.

Damn, why didn't I think of this step...

"Bingo! That's right." Lu Zhou nodded with a smile, thinking that children can be taught.

"Thank you... lend me the draft paper, and I'll take it and study it."

"Take it, you're welcome!" Lu Zhou waved his hand generously, stood up, and walked to the bathroom.

Taking Lu Zhou's scratch paper and returning to his seat, Liu Rui pushed his glasses, stared at the topic, frowned slightly, and fell into contemplation.

Although the solution method is novel, the problem-solving process is clearly written, and the knowledge points involved are not beyond the outline. Even without Lu Zhou's explanation, he can easily understand it.

It's just that he doesn't understand, how did that guy Lu Zhou come up with it?

And in such a short time...

Has this been done before?

Liu Rui thought about it, and it seemed that this was the only possibility. Otherwise, he couldn't imagine that this scumbag who was busy doing part-time jobs all day, actually crushed him, a well-recognized student of the class, in terms of problem-solving speed.

Turning to the back of the exercise book, Liu Rui looked at the solution, stunned for a moment, and muttered to himself.

"impossible……"

The answer is absolutely correct...but that's not the point.

The point is, Lu Zhou's solution is actually simpler than the standard answer! The answer does not take into account the solution of converting rectangular coordinates into polar coordinates, but directly applying the formula to split the integral twice, which also causes the amount of calculation to look extremely large.

And this is one of the solutions he has considered...

how can that be!

Liu Rui bit his lip.

Suddenly I felt a little suspicious of my life.
