Chapter 7: In front of Zhen Xue Ba, all mortals are dregs

In the end, reason defeated greed, and Lu Zhou dispelled this unrealistic idea.
It ’s nothing for a freshman student to publish sci itself, anyway, the phenomenon of irrigation in domestic mathematical sci journals is also very serious. As long as your English skills are OK, irrigation is like that.
This phenomenon of rampant and sufficient numbers, so that a good person, a list of several well-known irrigation journals in China. At the top of the list, Applied-Mathematics & (AMC) is famous in the field of irrigation.
He Shan said that going to university in Shanghai, in just four years, has published hundreds of mathematical papers on the AMC, and some punters fill more than 20 papers a year, which is not a problem!
In order to ensure the academic quality of theses, those well-established journals tend to strictly control the number of papers published in a year to less than 100. However, this "Big Mac Journal" is very skinny. It publishes more than 1,000 papers a year, plus cross-citing and other phenomena. The impact factor is upwards! Even due to the existence of a large number of pseudo-reviews, a certain editorial board posted more than 100 articles on it!
舟 Other SCI journals Lu Zhou may not be confident, but what AMC said ...
He said that he was confident and that he was inflated.
In short, Lu Zhou thinks the problem is not big.
However, the publication of Zhou's conjecture proof method in SCI journals is a big problem. It is 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 chose the third task, he did not plan to use Zhou's conjecture to prove it, but wrote a dissertation to do the task casually.
With his current understanding of advanced mathematics and mathematical analysis, he is no less inferior to graduate students. Coupled with the level of English, the distance from writing an English thesis is only a few professional terms, and these can be solved by looking up the dictionary.
In contrast to the other two tasks, the first one did not have that connection and thought that he had not had such a high EQ.
The second one, I have n’t even started a big one course in my freshman year. I ’m afraid that all the system will do high school physics exercises. The ghost knows how much the difficulty coefficient is. Moreover, the physics level is not so attractive to him. The name is only useful in the late and late stages. It is not too late to practice when needed.
After the mission was selected, Lu Zhou patted the grass on the fart. He stood up and hummed to the direction of the dormitory.
I waited so long outside and didn't go back, I was afraid that Liu Rui was mentally out of order.
小 This kid is very strange, although usually generous, but only in studying this, be careful to make people speechless. A glance at a note can chase you two streets, and asking a question can throw a dozen of your eyes away, probably this kind of person. In his eyes, it seems that the world is his competitors, and what he is chasing is probably not a high academic level, but it is the first in the eyes of a teacher or classmate, or the status of "learning tyrant".
Is this kind of person considered a Xueba?
Lu Zhou did not think.
In the eyes of Zhenxue Ba, all mortals are dregs, what about showing you my notes? Zhou guessed you would? You can't figure it out before you!
陆 In Lu Zhou's cognition, there seems to be only one person who meets the conditions of Xueba.
Huh, yes.
Don't doubt, he is talking about himself.
Uh ...
I pushed open the bedroom door, no more, no less, exactly ten o'clock.
瑞 Liu Rui is holding the exercise book to solve the problem. The other two are not in the dormitory, probably playing cards next door. Shi Shang belongs to people who usually listen to lectures at the end of the semester. As for Huang Guangming, it is probably the legendary of learning. He usually doesn't listen to the lectures and hugs the Buddha before the exam, but the scores are high.
Throwing the backpack on the table, Lu Zhou reached into the drawer to find his shower card.
At this time, Liu Rui put down her exercise book and looked at Lu Zhou's direction.
"Elbow, so hard?"
"I have to work hard. I haven't touched the book for almost half a semester. If I don't work hard, I won't have time." Throwing the bath towel on his shoulder, Lu Zhou stood up from the chair.
Seeing Lu Zhou going to take a bath, Liu Rui suddenly said, "I can't do a question here, can you help me?"
Alas, it's strange.
Do you still have questions you can't do?
"Let's take a look."
Lu Zhou held out his hand, Liu Rui pushed his glasses, handed the exercise book over, pointed at the circled topic and said, "That's it."
"Point problem? This stuff shouldn't be difficult ..." The question glanced over. The unexpected question type was not seen. Lu Zhou became interested and was not in a hurry to take a bath. He sat back with the exercise book. On the chair, pick up the pen and start writing on the draft paper.
If it was difficult for Liu Rui to solve the problem before, he would not be able to solve it. I don't know why, but at the moment there was no thought of "impossible" in his mind.
I watched Lu Zhou take a pen to calculate for a while, Liu Rui was relieved, secretly despising the sentence was indeed scum, no matter how pretend to be a slag.
Regarding this question, it is not false that he cannot solve it, but in fact there are reference answers, and there are detailed solutions on the answers. The reason why Lu Zhou was asked this question was not because he was open-minded to ask for advice, but just wanted to "stab the enemy".
With ten thousand steps back, even if he asked a math problem, he would not find Lu Zhou's scum.
Thinking like this, Liu Rui said, "Will you write down the question and do it? I think about the next question first?"
Qian Qian means that you will never write anyway, and I will not waste your time.
However, Lu Zhou's reaction was beyond Liu Rui's surprise.
"... no need, untie it."
Explain, unlock? !!
瑞 Liu Rui's eyes widened, and her eyes were almost protruding.
"Well, you heard me right." Turning the ballpoint pen in his hand, Lu Zhou explained to the formula on the draft paper. "It is a typical double integration problem. The first step is to convert the rectangular coordinates to polar coordinates and start the calculation. , Due to interval symmetry, this part of the equation can be reduced to cotx2 after calculation ... "
"Finally converted into cscx2 points! Substitute it into the original function!" Liu Rui's pupil contracted slightly, keenly seeing through the core idea of ​​this solution, and the next steps were like pushing the boat down the river ~ EbookFREE.me ~ You can do it without any difficulty.
Damn, I didn't expect this step ...
"Bingo! You got it right." Lu Zhou nodded with a smile, and said that Xunzi could teach.
谢谢 "Thank you ... I borrowed the draft paper, and I took it to study."
"Take it, you're welcome!" Lu Zhou waved his hand generously, stood up, and walked towards the bathroom.
I took Lu Zhou's draft paper back to the seat, Liu Rui pushed and pushed his glasses, stared at the subject, his frown slightly, and lost his thoughts.
Although the solution method is novel, the problem-solving process is written clearly, and the knowledge points involved are not super-level. Even without Lu Zhou's explanation, he can easily understand it.
I just let him think of something, how did Lu Zhou think about it?
And in such a short time ...
Is this kind of problem done before?
Liu Rui thought about it, it seems that this is the only possibility. Otherwise, he really can't imagine that this day and night, he was busy doing part-time study slag, and even overwhelmed his class of recognized hegemonies in the speed of solving problems.
I turned to the back of the exercise book, and Liu Rui looked at the answer. The whole man froze and muttered to himself.
"Impossible ..."
The answer is completely correct ... but that's not the point.
The key point is that Lu Zhou's solution is even simpler than the standard answer! The answer does not take into account the solution of converting the rectangular coordinates into polar coordinates, such as the deflection of the sword, but directly applies a formula to the second division of the integral, which causes the calculation amount to look abnormally huge.
And this is one of the solutions he considered ...
how can that be!
瑞 Liu Rui bit her lip.
Suddenly, I felt a little skeptical about my life.
