From failed candidate to chief scientist

Chapter 7 Challenge Mission
"Analysis and Applications of the Differential Mean Value Theorem."

The next day, Lin Mo sat in his old seat in the library and opened the documents Zhang Qihua gave him.

The differential mean value theorem is a general term for a series of mean value theorems, such as Rolle's theorem, Lagrange's theorem, Cauchy's theorem, Taylor's formula, Darbe's theorem, and L'Hopital's rule, all of which are powerful tools for studying functions.

The differential median value theorem is an important bridge connecting the derivative and the original function, so it is widely used.

The scope of this research topic was so large that for a while, Lin Mo didn't know where to start.

Lin Mo was going to read a book first to look for research directions and inspiration.

"Ding, challenge task: complete the analysis and application research of the differential mean value theorem, write and publish a paper on the analysis and application of the differential mean value theorem, the impact factor of the journal in which the paper is published shall not be less than 4. Task time limit: three months; task Reward: Any subject can be designated to be upgraded to one level."

Lin Mo: (｀Д)!!
This task is really challenging.

Lin Mo happened to read through mathematics journals two days ago, and he knew the situation of the journals very well.

According to the latest JCR database, there are only a handful of journals with no less than 4 journals in the field of mathematics. Except for the four major journals in mathematics, there are basically very few journals. It can be said that you can count them on one hand.

So this task requires publishing papers in the four major journals?
It's not difficult at all...

No wonder it's not difficult.

You must know that there are less than 50 papers published in the four major journals in China over the years. Now you want me, a freshman who has not yet entered graduate school, to publish one within three months?
This is simply an impossible task!
And this research topic...

It goes without saying that the differential mean value theorem is very important. Since they were proposed, they have been studied by countless mathematicians, and they have formed several major theorems today.

But if you want to write a paper based on this and be accepted by the four major journals of mathematics, just an overview of the analysis will definitely not work. The number of words in such a paper is only a few words in domestic journals. If you want to be accepted by the four major journals, there is no way.There must be major innovations and breakthroughs, such as proposing new theorems or making important discoveries in applications.

This difficulty...

But looking at the mission rewards, it would be a waste to specify any subject to upgrade to one level and use it on those subjects that are not yet introductory. Those subjects only need 100 subject points to unlock, but if Lin Mo upgrades mathematics to one level first, then Use this reward.

"System, what is the next level to the entry level? How many subject values ​​are needed to advance to the next level?"

"After the entry level is the proficiency level, which requires 10000 subject points and can be promoted to the next master level."

Hiss, that is to say, if this reward is used well, it is equivalent to getting 10000 subject points, which can directly upgrade mathematics to the master level.

If I had reached the master level in mathematics before that, does that mean...

"System, what is the level after master level? System, tell me, how are you graded? How many levels are there in this subject, and what are the subject values ​​required for upgrading?"

"Currently, there are four levels of single subject classification in the system, which are entry level, master level, master level, and hall level. The upgrade subject values ​​are 100, 1000, 10000, and 100000 respectively."

“The entry level is equivalent to the entry level of undergraduates to PhD students in the subject, the proficient level is equivalent to the level of PhDs to professors in the subject, the master level is equivalent to the level of everyone who has made certain achievements in the subject, and the hall level is equivalent to the most outstanding top disciplines in the subject in the world. A guide.”

Lin Mo probably understood after listening.

There is a subject value behind each level. The rating explanation given by the system should be the level corresponding to the subject value of 0 and the full subject value of the grade.

In other words, entry-level (0/1000) is equivalent to undergraduate students, while entry-level (1000/1000) is equivalent to entry-level PhD level.

The same proficiency level corresponds to the level from doctorate to professor.

As for the master level, according to Lin Mo's understanding, it should belong to the small group of people who stand at the top of the discipline, and they can be called the kind of family. For example, if Lin Mo reaches the master level in mathematics, then he has the same level as a mathematician. s level.

Of course, when they reach this level, their level can no longer be accurately measured in detail, so there is no way to distinguish between upper and lower limits. It is enough to collectively refer to them as one family.

As for the palace level, in Lin Mo's understanding, they are those top figures who have played a key role and left a mark in the history of their disciplines.

Take mathematics as an example, such as Archimedes, the god of mathematics, and Gauss, the prince of mathematics.

Hiss, Lin Mo took a breath of cold air.Calculating it this way, if this operation is done well, this reward can even make you become Archimedes or Gauss in one go?No matter how bad it is, it can still be Euler.

Even if he couldn't do it, he could at least directly improve Lin Mo's mathematics level to the master level, which was equivalent to gaining 10000 science points.

According to the current daily progress of 10000 points, he would have to work day and night for 100 days to obtain 100 science points.

Lin Mo's fighting spirit was instantly high. This challenging task must be won!

If there are difficulties, you have to go up, if there are no difficulties, you have to go up to create difficulties!

Because the system gives too much.

Faced with this, what is the difficulty?
Lin Mo immediately went to find a bunch of books about the mean value theorem, intending to study it carefully. First, he would master the basic theoretical knowledge, and then read related papers to understand the research progress and determine his own research. direction.

Just do it, Lin Mo picked up the book and plunged into it.

It wasn't until it got late and the library was about to close that Lin Mo reluctantly left. When he came out of the library, Lin Mo was still thinking about the mean value theorem.

"Hello classmate, excuse me, can I ask you a few questions?"

At this moment, a voice suddenly interrupted Lin Mo's thinking, and a beautiful figure stopped in front of Lin Mo.

Lin Mo came back to his senses and frowned as he looked at the cell phone camera lens that was about to hit his face.

"Student, do you think 800 yuan a month is enough for a college student? Do you earn it by yourself, or ask your family for it?"

Before Lin Mo could speak, the other person continued to ask.

"live streaming?"

Lin Mo looked at the other person and did not answer the other person's words. Instead, he asked a question.

"Yes, we are live broadcasting, classmate, please answer the question I just asked first."

The girl opposite nodded.

"Can you take a look at it for me?"

After saying that, without waiting for the other party to object, Lin Mo had already taken the phone from the other party.

"you……"

Lin Mo glanced at the screen and saw that the other party was indeed live broadcasting, but the number of viewers in the live broadcast room was pitifully small, no more than a thousand people. He didn't know how many of them were robots given by the system.

"You can't live broadcast like this..."

"Hmph, I want you to take care of it."

The girl across from him angrily snatched the phone back from Lin Mo's hand.

"If you want to increase your fans, you have to show your fans what they want to see."

Lin Mo returned the phone to the other party.

"Bah, don't think I don't know what you're thinking, don't think about it, dreaming!"

Lin Mo shrugged.

"I didn't think about anything, but where did you think about it?"
