Chapter 90 Fundamentals of Number Theory
After coming out of the counselor's office, Chen Zhou held a stack of books and walked through the strange look of looking at him. He finally returned to the dormitory.
Chen Zhou probably hasn't seen so many books before...
After breaking open the door of the dormitory, Chen Zhou took two steps at a time, walked to the table, and put the stack of books on the desk.
Zhao Qiqi, Zhu Mingli and Li Li immediately surrounded him, with many questions in his mind.
Zhao Qiqi asked, "Chen Zhou, where did you get so many books?"
Chen Zhou replied: "I asked the counselor to buy it. In the future, you have to look at the basic mathematics textbooks and you can get it from me."
Zhao Qiqi looked at the pile of books: "No, your pile of books is all basic mathematics textbooks?"
"Yes." Chen Zhou nodded and began to organize these textbooks.
"Okay, are you planning to teach yourself in advance?" Zhao Qiqi also helped Chen Zhou sort it out.
"This is what you plan to do now." Chen Zhou replied honestly.
"But some of this seems to be found in the course?" Li Li kept paying attention to these textbooks.
"Well, I have picked out all the courses." Chen Zhou nodded. He had divided the textbooks into two parts, one that you will learn immediately, and the other that you are ready to study by yourself.
I will learn several textbooks such as "Mathematical Analysis 1" and "Advanced Algebra 1".
Those who are preparing to study by themselves include "Basics of Number Theory", "Basic Algebraic Geometry", "Topology", "Differential Geometry", "Partial Differential Equations", and "Functional Analysis".
Li Li glanced at two piles of textbooks that were completely different and said, "Chen Zhou, if you really have to learn so much by yourself, it will take a lot of time."
Chen Zhou smiled faintly and said, "It takes a lot of time."
After sorting out the textbooks, Chen Zhou went out again and called Yang Yiyi to have dinner together, and then bought some daily necessities.
While having dinner, Chen Zhou thought of the stack of math books again and asked, "Yiyi, do you have many basic courses in physics?"
"It seems that there are not many things to look at the course arrangement. It mainly includes modern physics, theoretical mechanics, and ordinary physics." After a pause, Yang Yiyi thought Chen Zhou was worried that his course was difficult, so she said again, "I will be with you during the summer vacation."
The courses should not be difficult if you study self-study big things and high mathematics as your foundation."
"Uh...that's good. Then, let's lend me your textbooks too." Chen Zhou finished speaking, and took a bite of rice.
"Yeah, okay." Yang Yiyi finished speaking and glanced at Chen Zhou.
After dinner, the two went to buy daily necessities.
There are large and small pots, and there are also a large pile. This time, no one cares about Chen Zhou. This is the normal state of school starts.
After returning to the dormitory and neatly put everything in, Chen Zhou's college life officially began.
Sitting at the desk, Chen Zhou took out the "Basics of Number Theory" and started reading it.
Number theory is also called the "Queen of Mathematics". It is a pure mathematics and mainly studies the properties of integers.
Pure mathematics is a study that specializes in studying the laws of mathematics itself and does not aim at practical application.
Number theory was called arithmetic in its early days and its origins were very early, but it was not until the development of Fermat, Mason, Euler, Gauss, Riemann, Hilbert and others that number theory gradually became richer.
.
In fact, everyone has been exposed to the content of number theory a long time ago, but no one knows that it is called number theory.
For example, a number, divided by more than 5 and more than 1, and divided by more than 3 and more than 2, ask what is the minimum number?
The question is very simple. Use the general step-by-step satisfaction method to sort the number divided by more than 5 to 1 from small to the arrangement, and then find the smallest number divided by more than 3 to 2.
This is a number theory problem, involving Sun Tzu's theorem in number theory, also known as the Chinese remains theorem.
The book "Basics of Number Theory" that Chen Zhou read was published by Higher Education Press and written by Mr. Pan, a famous Chinese mathematician.
It mainly includes the divisibility of integers, number theory functions, some elementary results of prime distribution, congruence and other contents.
Starting from the basic nature of the whole dividing, Chen Zhou was fascinated by it.
For example, there are infinite numbers of prime numbers, and these theorems that can be said casually are also given corresponding proof methods in the book.
Learning knowledge requires you to go from shallow to deep, first understand the most basic things, and then study deeper levels.
Chen Zhou was watching with relish, but his thoughts were interrupted by the voices beside him.
Chen Zhou turned around and looked. Zhao Qiqi and Zhu Mingli were passionately shaking, frequently communicating, preparing to cross the tower.
Both of them, no, were they all brought their laptops.
Chen Zhou looked at it for a few seconds, then withdrew his gaze and focused on the teaching materials in front of him again.
After watching for a while, Chen Zhou put the textbooks together and took the basin to wash.
When he came back, he found that Zhao Qiqi and the others had started a new game.
Chen Zhou asked, "Did you win just now?"
While operating the hero, Zhao Qiqi replied: "That's necessary, keep winning. My output is invincible!"
Zhu Mingli spoke out and exposed him: "It's not my top laner that can withstand it. You can output under my crotch with peace of mind..."
Zhao Qiqi: "Yes, yes, yes...Brother is invincible... Alas, be careful of the hook..."
Chen Zhou smiled and stood behind the two of them for a while.
After the game, Zhao Qiqi turned his head and asked, "Chen Zhou, are you playing tricks? Hurry up and start the whole computer together?"
Chen Zhou replied: "I used to play, but now I basically don't play anymore. You guys play, I'll go to bed first. I've been taking the car for a day today, so I'm so tired."
After saying that, Chen Zhou climbed onto his upper bunk.
Lying on the bed, Chen Zhou glanced at Zhao Qiqi and the others who were fighting vigorously, and then silently planned the study time of the textbook.
At about 9 o'clock in the evening, Zhao Qiqi and the others finished their last game and did not drive again.
Instead, he turned off the computer, quickly washed up, and went to bed.
Chen Zhou noticed that the two of them lost the last game.
The freshman registration lasted for two days, and then the counselor Huang Yemei held their first class meeting.
Yan University School of Mathematics and Sciences has five departments, only the Department of Mathematics is considered as the basic mathematics category, and other four major departments include the Department of Probability Statistics, Information Science, Science and Engineering Computing, and Financial Mathematics. They basically belong to the category of applied mathematics.
.
This class of 14th-level mathematics college students have a total of nearly 200 students, while there are only about 30 students in the mathematics department, and they are in the same class.
When introducing himself at the class meeting, Chen Zhou found that most of the students in this class were admitted through competitions.
It can be said that it is a gathering of talents.
After everyone introduced themselves, the counselor briefly talked about school rules and regulations.
The class meeting ends, and the school will be welcomed in the next few days.
Such as opening ceremony, visiting the school history museum, admission lectures, welcome meetings, etc.
It is mainly to help new students understand the school, become familiar with the campus, and become familiar with new classmates.
