The review of a scientific paper takes three months to half a year, and an acceptance notice will be issued if the review is passed, and it will take even longer to officially publish, and it is normal to drag on for two years. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Therefore, Liang Yu and Liu Chen got the offer before the Mid-Autumn Festival, and the students were shocked, and they were all waiting to see how these two guys came up with the offer letter.

Nine times out of ten, these two guys can't get it, this is a common idea.

During his Ph.D. in his previous life, Liu Chen almost opened the threshold of several majors such as electrical, communication, mathematics, and control, and it is easy to produce high-level papers at the intersection of these disciplines, which is something that almost every scientific researcher knows, but it is already very difficult to fully control the knowledge of a specialty, let alone several majors, which requires great hard work and superhuman talent.

Liu Chen stayed in the library, just sent an email, the corners of his mouth rose to show a smile, just sending a paper, it was too simple for him.

……

Tuesday, East Courtyard 100 Multimedia Classroom.

At 7:30, when Wang Cong and Tang Xiao entered the lecture hall, they were all taken aback by this scene, it was overcrowded, crowded, and there were still a few empty seats in the last row.

The two of them were dumbfounded all of a sudden, Tang Xiao walked to the last row sullenly, Wang Cong also sat down next to him, Tang Xiao said angrily: "Let you get up early, it's so late, it's okay now, you can only sit here, so far away, you can't see it, you can't hear it." ”

Wang Cong knew that he was wrong, and muttered: "We have already come early enough, who knows that other students are even earlier, don't be so crazy." ”

"Hmph, no matter how crazy we are, we're all old! Tang Xiao ignored him with a straight face as he spoke, Wang Cong pulled her arm, "Don't we still have a strong backing from Senior Liu Chen, what are you afraid of?"

"The seniors are so busy, we have to try to cause as little trouble as possible to others. ”

The surrounding classmates were also discussing, and one of them said: "I heard the seniors say, our [Advanced Mathematics] teacher Xu Dabiao gave a very good lecture, and he was the most famous professor in the Department of Mathematics of our school, and let me listen carefully, I came at 7 o'clock this morning, I didn't expect the seats to be occupied here, these people are too unconscionable, I will come over to occupy the seat next time I get up in class." ”

"Yes, how did I hear that he was ruthless and notoriously strict, and he would write an after-class workbook for every class, requiring him to hand in before the next class, these questions are newly compiled every year, and he can't find the answer anywhere, and those who have taken his class are miserable. Another student replied.

The whole lecture hall is full of the sound of flipping books, whispering whispers, everyone knows from various sources that the most important course in the freshman year is [Advanced Mathematics], if you want a scholarship, if you want to be among the best, if you want to go abroad in the future to apply for a good school, this course must be won.

An old man in a sloppy dress walked in with a book in his hand, and as soon as he stood on the podium, the whole classroom suddenly fell silent, this is the aura.

"Students, I am your [Advanced Mathematics] teacher, Xu Dabiao, I won't say much about how important this course is, because students who don't even know this point don't think they need to listen to my class. The old man spoke unhurriedly and forcefully.

"In my class, I can sleep, I can snore, I can fart, I can not come to class, I don't come to class again, and my grades are usually in the workbook after each class. Okay, without further ado, let's get to class. ”

After Xu Dabiao finished speaking, he wrote a board book on the blackboard, and the writing speed was extremely fast.

The speed of this lecture is really fast, although almost all the students have studied in advance, and after two classes, their minds are also foggy, and they directly finish the first chapter of the huge amount of information, such as limits, convergence, and three elementary functions.

If nothing else, in high school, the three elementary functions take a month of class!

The top students were shocked, is this really a class? Isn't it just turning the book?

Ninety minutes of time, directly talking about the points, this speed is really drunk.

At the end of class, Xu Dabiao threw down the blank workbook and walked away directly, leaving a group of students rubbing their temples, their heads dizzy and swollen, and the students were dumbfounded when they received the workbook...... It's such a difficult topic, and there is no buffer time at all.

Suddenly there was an illusion that a scholar had become a scumbag.

Wang Cong rushed up and took two copies back, and when he saw that the first question was exactly the method Liu Chen had said before, he was immediately overjoyed, but when he saw the second question, he began to frown, the third question frowned deeper, and the fourth question was completely wrinkled, giving Tang Xiao a copy, and said with a wry smile: "This topic is really difficult!"

……

Jianghai University at night, under the afterglow of the setting sun, there is a different kind of beauty, and the top students who have taken a one-day course do not feel tired at all at this time, but excitedly start to do the [Advanced Mathematics] workbook.

As soon as Wang Cong returned to the dormitory, he saw the other three roommates discussing the workbook.

"I can't understand this first question at all, how do I do it?"

"Brother Biao deserves to be Brother Biao, this dismount is really ruthless enough, and my self-confidence was suddenly hit to 0. ”

"It's already good that you're 0, I've been hit into a negative and need to top up urgently. ”

"Does this series converge or not? It doesn't seem to converge, and it still needs to be proven!"

Wang Cong was a little itchy when he heard this, he knew the first question completely, and said indifferently: "This number series is an infinite multiplication of terms, each term is greater than 1, it seems that there is no upper bound, and it cannot be converged!"

"But no, this sequence has no boundaries at all!

"But looking at the meaning of the question, it must be able to converge, otherwise how can you say whether this sequence of numbers converges and prove!"

"The first question is stuck, can you still have a good time?"

The discussion was intense, and everyone really couldn't get used to the first time so fast in class, the first time they couldn't do so many questions, and they couldn't find the answers at all.

Wang Cong remembered Liu Chen's calm appearance at the beginning, and unconsciously imitated it, and said lightly: "However, this number series is indeed convergent!"

Everyone looked at him strangely and hurriedly asked, "How can it converge? Can unbounded sequences converge too?"

"You've made it? Tell us about it! Save me, who only scored 140 points in mathematics in the college entrance examination, I'm a scum compared to you. ”

"Let's also talk to my poor people who didn't take the college entrance examination, hey, my heart has been scattered for a few months, I really shouldn't agree to be sent in advance, I didn't take the college entrance examination, my life is too incomplete. ”

Wang Cong has four people in this dormitory, one is escorted, and the other three have math scores of 140, 145, and 147 respectively, and Wang Cong is 147, and 140 points have become the bottom.

Wang Cong smiled and said, "I learned a square difference formula in junior high school, remember?"

Somehow, when he said this, he felt quite refreshed. (To be continued.) )
