I really don't want to skip a grade

Chapter 268 Xiao Dong's Motivation to Study Mathematics

[My system currency is not enough for small business. 】

In an aesthetics class in the afternoon, Li Yishu handed Xiao Dongfei a note.

Xiao Dong knew what this meant. Ju Xiaotian and Bai Xue's hospitality to Li Yishu during lunch gave Li Yishu a headache, and he expected to harass Li Yishu in the future.

Not only that, Miao Xiaolong also suddenly began to show courtesy to Li Yishu, which made Li Yishu feel very uncomfortable.

This is all the result of Xiao Dong's misfortune, so it is Li Yishu who is asking Xiao Dong for this debt.

[You can borrow money from the system. 】 Xiao Dong replied.

He himself only has more than 1700 system currency now, which is enough for a small business, and he really has no money to borrow Li Yishu.

The upper limit of funds that a heroic brass can borrow from the system bully is 1000 system coins, which is enough for Li Yishu to do small business in the system trading area.

[I don't want to borrow from the system bully, the interest is too high. 】Li Yishu persisted.

[You can't even earn back the interest in business, so what business are you doing? 】 Xiao Dong ridiculed.

[Then how do you do business?Can the guidance card be borrowed for me? 】 Li Yishu said.

Xiao Dong understood that this was Li Yishu's real purpose.

Her newly drawn AI assistant should be temporarily unable to provide her with price guidance for various items and services in the system trading area.

Xiao Dong used WeChat to send her a long list of market prices for various items and services in the system trading area, and Li Yishu stopped talking.

[Don't patronize small business, pay attention to taking notes. 】Xiao Dong glanced at the teacher who was talking about aesthetics on the podium.

[Can't delay. 】Li Yishu replied.

It's no pressure for her to multitask like this.

Xiao Dong felt relieved and continued to immerse himself in the study of mathematics.

He can't concentrate on several things when he studies mathematics and physics, so after shielding him from outside interference with a magnetic field, he immerses himself in the quantity and space form of mathematics.

The bully of the system allowed him to make a world-renowned mathematical achievement before the age of 20, so it is impossible not to work hard.

And before he made that world-renowned mathematical achievement, he must publish a few more important SCI articles in the field of mathematics, otherwise, even if you do make a world-renowned mathematical achievement in the future, Xiao Dong also suspects that few people will pay attention to his mathematical achievements, and it is even more difficult to recognize them.

And as far as mathematics learning itself is concerned, it is also a gradual process.

But just when Xiao Dong was about to write an SCI article on his own, he realized that he didn't have such a knowledge reserve at present, and it was even difficult to set up a topic.

Du Chen can do it on his own, but that doesn't mean that Xiao Dong can also do it independently. There is still a big gap between Xiao Dong and Du Chen in terms of mathematical knowledge reserve.

And he "stealed" many memories and thoughts from Mr. Yang, and he couldn't digest them at all. The biggest problem in it turned out to be the obstacle of mathematical reserves. One of them, but his achievements in physics are based on his extremely powerful reserve of mathematical knowledge.

Therefore, he, Xiao Dong, has to grit his teeth and work hard on mathematics, there are not many shortcuts to take.

But mathematics is really too brain-burning!
As you learn a certain level, as you get deeper and deeper into the huge maze of mathematics, you will sometimes be so confused that you don't know what you are learning!

What is math?
Ultimately, it is a discipline that studies concepts such as quantity, structure, change, and spatial models.

This definition can be solved with just one sentence, but mathematics takes algebra, geometry and analysis as the core fields, but it has extended more than 100 branches step by step!
The number of common branches can also tire you out of breath: history of mathematics, mathematical logic and mathematical foundation, number theory, algebra, geometry, algebraic geometry, topology, mathematical analysis, non-standard analysis, function theory, Ordinary differential equations, partial differential equations, dynamical systems, integral equations, functional analysis, computational mathematics, probability theory, mathematical statistics, applied statistical mathematics, operations research, combinatorial mathematics, fuzzy mathematics, quantum mathematics, variational mathematics...

Don't talk about studying each branch intensively. For ordinary undergraduate students, do you know what each branch covers?

If you really want to study and study these branches one by one, you really have to learn to die!

Fortunately, Xiao Dong's mental strength is far superior to that of ordinary people, so he went down one branch after another in the first semester of his freshman year, and his study intensity far surpassed that of other students in the same grade (except Du Chen), and he can still do it up to now. live.

Moreover, the deeper he dug, the more he discovered the inextricable connections between the various branches of mathematics and the process of deducing each other.

The more he learns, the more he realizes the wonders of mathematics, and the more he understands and masters the characteristics of mathematics. Mathematics based on mathematical logic and set theory has three most important characteristics: one, abstraction, two. , is the accuracy, and three, the extreme breadth of application.

Mathematical abstraction.

Starting from the two simple concepts of integers and straight lines, then rational numbers, irrational numbers, complex numbers, functions, differentiation, integration, n-dimensional space and even infinite-dimensional space..., more and more abstractions!

Abstraction is not a characteristic of mathematics alone, it is a characteristic of any science.But the characteristic of mathematical abstraction is that it only retains quantitative relations and spatial forms and abandons everything else, and it is almost completely surrounded by the circle of abstract concepts and their interrelationships.

So it's the most fucking abstract of all disciplines!
Of course, this kind of abstraction also has an advantage. Other natural scientists have to keep doing experiments to achieve results, and produce results in experiments.

Mathematicians don't have to bother!
They carry one head on their shoulders, and they only need to use their own head to prove the theorem through reasoning and calculation!
Proving a major theorem is your major research achievement!
Is it possible to save a lot of funds and conditions?

So it is reasonable for the system bully to let Xiao Dong make a world-renowned mathematical achievement before the age of 20. Other subjects require huge funds and laboratory conditions. If you don’t use mathematics, you can use your brain to do it. Just think about it!

The second characteristic of mathematics is its precision.

Definitions are precise and clear, reasoning is logically rigorous, and conclusions are certain and indisputable!
So in the world of mathematics, you don't have to have a tongue and a spine to say whatever you want to say!
Your power and authority stuff doesn't work with math!

As long as the theorems and derivations uttered by a teenage hairy-headed doll are correct, they are correct. You, an old brick with silver hair and fairy spirit, can only bow your head and give in!
Therefore, mathematics makes it possible for the poor in this world to give birth to noble children and jump the barriers of social class!
The third characteristic of mathematics lies in its extreme breadth of application!
As the late famous mathematician Professor Hua Luogeng once pointed out, the universe is big, the particles are small, the speed of rockets, the ingenuity of chemical engineering, the changes of the earth, the mystery of biology, the complexity of daily use, mathematics is everywhere!

Mathematics is indispensable wherever "quantity" appears. Mathematics is indispensable for studying the relationship between quantities, changes in quantities, and the relationship between changes in quantities!
Mathematics is the mother of science is reflected here!
Therefore, mathematicians are useful, and those who are useful are glorious. Those who are glorious will get great respect from society. If you get great respect from society, you can marry two or three wives (quickly cross it out quietly)!
So Xiao Dong is now desperately studying mathematics.

This is the motivation for Xiao Dong to study mathematics.

Otherwise, he would not be able to study for a day.
