Chapter 150 Number Theory is very interesting

As a talent who has been excavated, Xu Chao does not feel that he has anything special, he is just one of thousands of ordinary people, and he cannot be said to be mediocre in the past thirty years, but he is far from being successful.

Xu Chao came from an ordinary rural family and went to high school and college with excellent grades, but he just read an ordinary book, and he couldn't find a job that was too satisfying, so he simply went to graduate school.

A few years later, it is already very popular to graduate with a master's degree, and you can easily enter the national department and work in top enterprises.

Xu Chao felt that he had been fooled by his mentor.

After graduating with a master's degree, I didn't know what to think, so I followed my supervisor to continue to study for a doctorate, two and a half years of graduate students, three years of doctoral students, and the youth of my twenties were all spent on studying.

Of course.

The Ph.D. background is really powerful.

Xu Chao is enough to find a good job in a large company, but he is still very unwilling, he feels that his youth has been squandered, he has been working in the laboratory, and he has to adapt again when he finds a new job, and he doesn't know what the future prospects are.

He also enjoys research.

Xu Chao's dream is to always engage in research work and stand at the forefront of the Internet and computer technology, and he has been working hard to achieve this.

But people always have to face reality.

The doctoral students who stay in the laboratory are the same as the doctoral students in the rover, they have the same name as 'postdoc', and some people will think that postdocs seem to have a higher degree than doctors, but this is not the case.

Postdoc, which can be considered 'after completing a doctorate', refers to a person who has obtained a doctorate and has chosen to continue working in the research field at a research station or at a university, laboratory, research institute, etc., without going out to find a formal job.

Generally, postdocs are not officially hired, such as laboratory work, postdocs are 'mobile', and the unspoken rule is to leave if they can't be promoted for three years.

In the intelligence and automation laboratory where Xu Chao is located, he can leave directly if he cannot be promoted to associate professor after three years of postdoctoral fellowship.

Xu Chao's scientific research ability is very strong, and he is Luo Zhijin's 'right-hand man', and there is no big problem with the rating rising, but he also has to face very real problems-

Even if he can be promoted to the rank of associate professor normally, his salary has not improved much, and it is much worse than going to work outside.

Now Xu Chao can only receive 7,000 yuan a month, including the state's subsidies for highly educated and scientific research talents.

It's bleak.

On the one hand, Xu Chao hopes to stay and work, but on the other hand, he is also worried about his income, he is just from an ordinary rural family, and his worth can be said to be nothing.

When will this salary scale be mixed up?

So listening to Zhao Yi talk about entrepreneurship, Xu Chao was immediately moved, he felt that the best way out is to join a potential computer entrepreneurship team, while continuing to do research and development work, challenging cutting-edge technology, on the other hand, the future can also be expected.

After watching Zhao Yi's video, Xu Chao was not only moved, he wanted to rush to Zhengyang and talk to Zhao Yi in person.

That robot can make instant coffee, he knows the technical content too well, not to mention what can be developed in the future, as long as the internal technology of the robot is realized, it is definitely a lot of income.

This strength is right in front of you!

The potential and strength of the computer industry are always technology, especially in the high-end field, technology is more important than anything else, and some teams master cutting-edge technology, and cutting-edge technology almost represents a 'monopoly'.

Monopoly, how much interest?

Xu Chao felt that he should talk to Zhao Yi face-to-face.

......

South Island.

Zhao Yi enjoyed a week with peace of mind, either going to the beach to bask in the sun, or going to nearby scenic spots, and then having the interest to go to sea to snorkel and fish.

It's such a comfortable day.

But after a long time, the comfortable days are actually not interesting.

Zhao Yi is the most depressed or has Zhao Hongjuan!

When walking on the road with the three women, many people cast envious eyes, because the three of them are eye-catching beauties, and only Zhao Yi knows Zhao Hongjuan......

Really parents!

For example, she asked Lin Xiaoqing and Zhao Linlin not to go to Zhao Yi's room after nine o'clock in the evening.

That's too much, isn't it?

BEFORE ZHAO YI CAME, HE IMAGINED THAT HE WOULD FIND AN OPPORTUNITY TO DRINK, SING AND HOLD A SMALL PARTY WITH LIN XIAOQING AND ZHAO LINLIN IN THE HOTEL ROOM.

In case of...... Ahem.

Sitting on the plane back, Lin Xiaoqing was sleepy, and put her head on Zhao Yi's shoulder, and Zhao Hongjuan, who was on the other side of the aisle, kept looking at her with supervised eyes.

Zhao Yi could only recite the incantation, "Color is emptiness, emptiness is color, the woman under the mountain is a tiger, you must be careful ......"

This trip is very familiar.

Looking at the appearance of Lin Xiaoqing and Zhao Linlin, you can know that they fell asleep sleepily when they got on the plane, and they didn't have the spirit to come at all.

The mentality of a few people going back is still very good.

When most people travel during the Spring Festival, they will look forward to going back to reunite with their families.

None of them are like that.

Zhao Linlin's parents are abroad, and she won't come back for the Spring Festival, of course she has relatives when she goes back, but her parents are not around, and her mentality must be different.

Lin Xiaoqing and Zhao Hongjuan didn't even have the heart to go back, because during the period before and after the Spring Festival, Lin Xudong spent almost all of his time working overtime, and he couldn't go home twice at all.

Zhao Yi's reasons are different, he is used to it, and he has nothing to worry about at home.

Both parents are still young.

In the past six months, his changes have affected his family, his parents have face in front of relatives and friends, and they are not worried about his college entrance examination, and life must be very good.

Of course.

Zhao Yi still has a lot to do, he was bored on the plane, so he simply studied the system.

The achievement task function of the system is the latest to be loaded, probably related to the learning coin, scientific research currency or academic prestige, and he is about to obtain the third ability, and he is also very much looking forward to it.

The achievement task function has been refreshed with two tasks, one is the robot automatic shopping system, and the other is the Goldbach conjecture.

Zhao Yi researched the principle of task refresh.

Tasks are marked with the exact account, that is, each account refreshes one task.

"How do I activate tasks for other subjects?"

"The achievement module is loaded, and it must be related to academic prestige, so quest activation is also related to academic prestige......"

"I have academic prestige in computer science and mathematics, so I can activate the achievement tasks of these two subjects, and to be able to activate other subjects, I must achieve certain scientific research achievements in other subjects?"

It's difficult!

For example, biology and chemistry, let alone completing scientific research achievements, he may not even get a perfect score in the exam.

Zhao Yi simply shook his head and didn't think about it, he opened the two refresh tasks to check, the 'robot automatic shopping system' has nothing to study, he knows how to complete it.

Goldbach's conjecture?

He suddenly had a surprising thought, "Maybe the system has refreshed the characters, which means that I have the ability to complete it?"

"...... with existing knowledge"

Ponder!

That's right, Research Coins!

[Research Coins: 85.] 】

[Use Research Coins to improve causal thinking.] 】

[Scientific Research Coin -1, assist in improving the ability of causal thinking, and obtain the effect of inspiration. Duration: sixty minutes. 】

After entering the state of 'causal thinking', Zhao Yi did not think about Goldbach's conjecture for the first time, but glanced at Lin Xiaoqing next to him, and fell directly into a state of distraction.

"She didn't even fall asleep?"

"Pretended?"

"Did you deliberately lean on my shoulder?"

This girl!

A smile appeared at the corner of Zhao Yi's mouth, and he reached out and secretly held the little hand underneath.

Lin Xiaoqing was clever, but she still pretended to be asleep and didn't take it away, and her face showed a touch of redness.

Zhao Yi smiled.

He didn't waste any more time, and immediately thought about Goldbach's conjecture, which was very simple, the original version was 'any integer greater than 2 can be written as the sum of three prime numbers', but the most common way to state it today is the famous mathematician Euler's version, that is, 'any even number greater than 2 can be written as the sum of two prime numbers'.

Prime numbers are prime numbers.

When thinking about Goldbach's conjecture, most people will start with the law of numbers, that is, they will think of the law of prime numbers 'very smoothly'.

Zhao Yi is the same.

He immediately thought of using a computer to design a program to verify prime numbers, the program design is very simple, and some computer algorithm knowledge can be completed, which is basically a certain number range to find the remainder verification.

And then......

There is no then.

Goldbach's conjecture is a super-difficult mathematical conjecture for hundreds of years, and the law of prime numbers is also a super-difficult problem, definitely no worse than Goldbach's conjecture, but the branch of the law has 'twin primes', as well as several related mathematical conjectures.

So in fact, trying to find the angle of the law of prime numbers to solve the Goldbach conjecture will not work at all.

Zhao Yi tried for nearly half an hour with 'causal thinking', and finally decided to give up and continue thinking, and his only gain was that he was determined that the system release task had nothing to do with his ability at all.

This is also normal.

Otherwise, the 'refresh task function' will not become an ornament?

"This system ......"

"It can't be the future Penguin Company, right?"

Zhao Yi complained silently, feeling still very unwilling, a scientific research coin is wasted, he came to the South Island to see the sea, and only then did he get two scientific research coins.

My heart hurts so much that I can't help myself!.

In the process of constantly thinking about the law of prime numbers, Zhao Yi suddenly found that numbers are indeed very interesting, and there are really many mysteries in them.

He immediately decided, "When I go back, I will study the theory of numbers when I have time." Kakutani's theorem is the content of number theory, and if you learn a lot of esoteric knowledge of number theory, you can study other things."

"What if we can really figure out the law of prime numbers...... Wouldn't all a whole bunch of related prime conjectures be easily proved by me......"
