Attached middle school, late at night, in a teacher's building.

Feng Yao finally checked the final math scores of the first-year high school students to see if the math he had paid attention to had improved significantly in mathematics.

He is still insisting on only taking high school freshmen every year, one session after another, ushering in the send-off. Principal Qu has repeatedly proposed: "Take a good class, if you teach it for a long time for three years, it will be easier to get grades in mathematics." And as a class teacher, the performance bonus is more. ”

Feng Yao refused with a smile every time, if he just looked at the money, he would not have embarked on the road of education.

In recent years, the employment environment for mathematics majors has become better and better, and it is particularly popular in the world, and Wall Street giants seem to have taken a fancy to mathematics majors and would rather give up economics and finance.

It's very unusual.

In China, the highest salary is Internet big data processing, and mathematics students are still used. However, the requirements are very high, and the positions are basically monopolized by top universities.

Only mathematics practitioners understand that in second-class institutions, mathematics is of low difficulty, textbooks are uneven, and even preachers are half-understood, how to learn things.

"It seems that in the past two years, there have been a lot of mathematical talents in second-class universities, as long as they set their minds to study. After graduation, he was robbed by Wall Street and the domestic financial market. ”

This made Feng Yao feel a little novel, contacted his former alumni, and finally found some reasons through various channels.

I don't know when and where, two rigorous Western translation series circulated on a small scale, and then detonated on the Internet, from the words and tone of expression, it should be the same person.

The UTM and GTM series, which Feng Yao once used, have no English accumulation for mathematics majors, so it is extremely difficult to read.

"Quite well documented. It is estimated that a certain power in China is afraid of affecting other people's jobs and retaliation, and is afraid that the author will pursue the copyright, so it is low-key and free to publish. ”

The domestic mathematical environment is very complex. The dispute between the north and the south, the dispute between domestic and foreign countries, Jingda and Mizuki, Nankai and Mizuki, Aurora and Nankai, will always break out once or twice a year.

The more famous the scholar, the more he will personally anger all parties.

Publishing books is related to fame and interests, and no one is willing to give it up. Therefore, there are very few willing translators in the market, and they feel that the workload is a waste of time.

"These two series have indeed benefited countless people, and I hope that one day, the author can stand up and be recognized by the world. ”

After counting the results of the students at hand, Feng Yao was concerned about the list of new students in the lower realm.

Every time a freshman enters the school, Feng Yao will report with great enthusiasm to see if there is a chance to find good seedlings.

Year after year, the cycle repeats.

His coldness is just pretending to be seen by outsiders, and he is willing to devote his energy to good seedlings.

"It's a pity that the comprehensive quality is indeed good every year, and the top seedlings are ...... Why is there less of it?"

In recent years, whether it is the admission rate or the admission rate of prestigious schools, it can be compared with the ninth middle school. Wuzhou's current high school reputation is not one big and three small, but two big and two small.

If you look at it according to the base, it should be a blowout of talents.

Feng Yao is a pity for this, he feels that his thinking is very problematic, and every top mathematics student who enters the school has expectations, and his best result is only to stop at the mathematics winter camp twice.

He reflected on his mistakes because the sense of anticipation was too strong.

The high school has only been shortlisted for two winter camps in 20 years, and two of them have achieved very good results in the past six years. Compared with the student who dominated the world's high school, the junior is indeed not competitive.

"Sleep, what time is it? The wife urged in the room.

"Got it. ”

It was 11 o'clock in the evening, and just as he was about to turn off the light in his study, the phone rang.

Looking at the name displayed on the phone, Feng Yao was out of his mind for a long time, and he hadn't really contacted him for more than a year, so he condoled with each other during the New Year's holiday.

"Teacher Feng. On the phone, Yang Fan's voice was tough and excited, "Two trillion seven thousand six hundred eighty eight thousand nine hundred nine thousand six thousand six hundred and forty-nine (2760889966649), two trillion seven thousand six hundred eighty eight thousand nine hundred nine hundred sixty six hundred and fifty-one (2760889966651)." ”

"What, Yang Fan, what are you talking about?" Feng Yao didn't react for a while.

"Teacher Feng, primes, twin primes, I found them again. You said that if you count it, you will find it one day. ”

Feng Yao was like a blow to the head, his brain was buzzing and exploding, suffocating and filling his heart, that kind of loneliness with persistent belief, even if it was across the ocean, even if it was between heaven and earth, he felt the same way.

He can imagine that in order to reject that loneliness, Yang Fan counted them one by one on every homesick night.

Until now, more than two trillion, how many days and nights have been counted, and how long have you spent being lonely.

Persistence and persistence.

The faint sadness made Feng Yao burst into tears and choked up: "Yang Fan, don't ...... Count, count...... Not only. ”

Yang Fan was silent, quietly making Feng Yao think that the signal had disappeared: "Yes, there are too many to count." ”

"Put it down for the time being, Yang Fan, you are still young. ”

For the first time, Feng Yao begged the student to stop math, he thought he wouldn't say such a thing, but he really couldn't bear it.

Why insist.

Yang Fan went abroad for four years, and he didn't return to China once, and he called and contacted him, and every time he said, it was very good, very calm, and the road to knowledge was very fulfilling.

In fact, everyone forgot that he was only in his twenties, but he was too tired to let an ascetic practice like that.

"Mr. Feng, ten years, the Fields Medal is only four years. ”

"Don't worry, you can use twenty or fifty years, I will keep myself alive, lying on the bed and unable to walk, I will also keep my eyes open and wait for you to send the trophy. ”

Feng Yao's tears fell one by one, and his eyes were already blurred, and this student, just for the sake of a joke and a willful comparison, staggered forward in loneliness.

As if feeling that the teacher was in a low mood, Yang Fan calmly comforted: "Teacher Feng, don't get excited, I'm very confident." In four years, I have earned a Ph.D. in Medicine, a M.S. in Biology, a Ph.D. in Mathematics, a M.S. in Chemistry, a Ph.D. in Physics, and a ...... in Economics I have a lot of certificates for those who are related to natural science. Teacher, I'm working hard and I'm amazing. ”

"Don't learn, Yang Fan, don't learn. Stop. You are already the best student in a hundred years, and now you only lack time to precipitate, please, don't learn. ”

That piece of academic qualifications, like a spike, pierced in Feng Yao's heart, is too much, too bitter.

"Ah, I'm already so good. Yang Fan woke up from a dream and sighed, "Then, Teacher Feng, I'm going back to China." ”

Yang Fan's only belief is to end his studies as soon as possible. Take the top knowledge he has learned all his life from the West to the East.

His thoughts flew across the Pacific Ocean, through the magic capital, and came to Wuzhou.

It seems that many years ago, that mediocre teenager was in the company of games every day, and at that time, he was simple and happy.

With great power comes great responsibility.
