Yang Rui slept for a few hours, but did not get up immediately, but lay on the lower bunk and reviewed the advanced mathematics in his mind.

For students majoring in biology, advanced mathematics, like physics and chemistry, cannot be said to be extremely important. However, as an interdisciplinary subject, mathematics, physics and chemistry are essential for biological research.

A good biology researcher must be good at one of mathematics, physics and chemistry; an excellent biology researcher must have no shortcomings in basic disciplines; a Niu brand biology researcher must be good at basic disciplines and proficient in one or two of them.

If you want to be a blue-collar worker in scientific research, you can just have a foundation for basic disciplines and spend more time on the biology major itself.

However, if you want to be a white-collar worker in scientific research, or go further, and be the so-called boss of other scientific researchers, it is essential to be good at basic disciplines and even proficient in them.

Yang Rui was not going to copy the experiments and professional skills in his mind for the rest of his life. Such a life was too boring. Instead of doing this, he might as well make some money to enjoy life.

If you do scientific research without a real level, there will be no problems in a short period of time, but there will be problems in the end. Just like undergraduates will have graduation defenses, researchers will also encounter questions at various international conferences. If you want to apply for a faculty position, or any title recognized by any country or organization, defense is essential.

Even Nobel Prize winners are still difficult to avoid real problems. Although there will inevitably be academic valves in the field of science, if they do not have tough strength, academic valves will only encounter more challenges.

Just like those large multinational pharmaceutical groups spend hundreds of millions of dollars on various litigation wars every year, billions on various marketing wars every year, and tens of billions on various R&D wars every year. However, small and medium-sized pharmaceutical companies will still spring up like mushrooms after a rain and continue to challenge them. Although there are not many successful people, but falling super pharmaceutical companies are still common.

If Yang Rui wants to make a difference, the amount of knowledge he has mastered is not enough. Of course, any researcher will never have enough knowledge. As a graduate student in 30 years, Yang Rui is ahead of the times in terms of knowledge structure and knowledge content, but the thickness is not certain.

On the bright side, the knowledge accumulation of domestic university professors in the 1980s may not be as rich as that of master students 30 years later. If we remove the backward knowledge, foreign professors in the 1980s may not be much higher-end than Yang Rui.

Everyone can say that they are on the same starting line.

However, unlike blue-collar work, lifelong learning is essential at the forefront of scientific research.

Any professor and expert who still want to continue publishing papers or writing papers needs to constantly learn new things, constantly read new papers and books, and constantly study a certain field.

Otherwise, at most two or three years of hard work, they will be abandoned by the advancing scientific research army.

Yang Rui is happy to do this. It should be said that he loves scientific research life from beginning to end, but some people have the opportunity to do scientific research, while others do not have such opportunities.

Once upon a time, Yang Rui was a person who had no chance, but now he has reached the threshold of scientific research life.

After four years in college, Yang Rui was ready to read some books. It was not necessarily the books in school, but also the books that had long been preserved in his mind.

As for the current environment in China, schools are also the most suitable place for academic research. If you leave the school, it will be difficult to find such a quiet and upward environment again.

Yang Rui was lying in bed learning knowledge and thinking about life, and Wen Xiaoman quietly lay on the upper bunk, observing Yang Rui.

Her mother Ma Lihua fell asleep opposite the upper bunk and her father fell asleep on the lower bunk. Wen Xiaoman could look at the male god with confidence without worrying about being discovered by her parents.

This kind of visual enjoyment, which is a bit exciting and happy, makes Wen Xiaoman unable to stop.

"He looks like a person walking down the screen." Wen Xiaoman compared with the teachers in the school while watching.

She studied at the Affiliated High School of the Central Conservatory of Music, which was difficult to take, but it was one of the best middle schools in the country with art majors. After graduation, students here could easily be admitted to art universities.

Compared with peers who rely on cram schools to learn music, art, dance and performing arts, the students of the Central Conservatory of Music High School are much more competitive. On the one hand, this is because the school has a good source of students, and on the other hand, it is because of the good teaching conditions, which has formed a virtuous cycle.

Most of the teachers who taught Wen Xiaoman received formal music education. In the 1980s, when popular entertainment was not yet popular, they were at the forefront of fashion. There is no doubt that these teachers also tried their best to show their distinctive side.

Whether it is handsome, cool, or heating... the teachers of the affiliated high school are more eye-catching than the gray passers-by.

However, compared with Yang Rui, the teachers in the affiliated high school have a bad foundation, and the fashionable clothes and dressing in the 1980s were not much better.

The more Wen Xiaoman read, the more fascinated she became. She suddenly regretted that she was not learning art, otherwise she could draw Yang Rui now.

"The Boy in the Soft Sleeper Carriage" may become a famous painting.

Wen Xiaoman became obsessed with thinking.

"What are you thinking?" Yang Rui suddenly opened his eyes and looked at Wen Xiaoman.

"I...I don't know either..." Wen Xiaoman was a little panicked and calm, and she was still lying on the upper bunk, facing Yang Rui.

Yang Rui looked up and could see Wen Xiaoman's slender long legs and pure big eyes. He couldn't help but smile and said, "I don't know what I'm thinking, I'm just dazed?"

"Who... was in a daze?" After Wen Xiaoman said that, he felt that his momentum had been greatly weakened, so he asked, "Why do you bring so little things when you go to school?"

"A suitcase and a backpack are a lot."

"I think other students have to memorize a lot of things to school, and the closer they are to school, the more they are." Wen Xiaoman finally said it smoothly.

Yang Rui smiled and said, "Aren't I far from the school? The train cannot arrive for a day and a night."

"Do you have a car to sit in, or do you still have a soft sleeper?" The girl seemed to be stoking. The hard seats are now airtight, making it more difficult to sleep softly.

Yang Rui also smiled: "Aren't you sitting in a soft lie down?"

"I... just sat down this time." The girl spoke with a small voice, but her mood gradually became beautiful. She looked at Yang Rui again and asked, "Are you listening to walkman?"

"Yes, you know walkman?"

"Of course, my classmate also bought it. What about you? Did your father buy it for you?"

"I bought it myself."

"Is this a very expensive thing?"

"It's not cheap, I bought it with royalties." Yang Rui was going to use this excuse for a long time.

"What did you write?"

"Some popular science articles, and things about middle school teaching."

"So amazing." Wen Xiaoman gave a satisfying praise. Any male animal will tense all its muscles when hearing such praise.

Wen Xiaoman did not doubt Yang Rui. The other party was a student of Peking University. Since this is the case, it is natural to get royalties for publishing articles.

He is handsome, and has been admitted to Peking University and can write articles to earn royalties. Wen Xiaoman thinks that this should be the most perfect boy he has ever seen.

The most important thing is that this is the most handsome boy she has ever seen. Even in the music school, there are not such handsome and stylish boys.

Wen Xiaoman didn't even think about how much money he had to write to earn a walkman. She looked at Yang Rui with great admiration and said, "It would be great if I could write articles too, so that I could buy tapes and music scores by myself."

"You can listen to me first." It's always pleasant to be praised by the girl. Yang Rui generously took out the walkman, handed it to her with a few tapes.

Wen Xiaoman leaned over and showed beautiful curves, and his fingers also touched each other gently.

Yang Rui's fingers are warm, Wen Xiaoman's fingers are cold, each with different touches.

Wen Xiaoman unconsciously bent his fingers, and it was too late to regret it any more.

"Thank you." Wen Xiaoman put on the headphones in a elegant manner, and gently turned on the play button under Yang Rui's instructions.

The melodious singing sounds flow out like spring water, which is beautiful and intoxicating.

There was a gentle singing voice in his ears, a handsome male god in his eyes, and Wen Xiaoman's comfortable eyes narrowed.

Yang Rui smiled, sat cross-legged on the bunk, unfolded a stack of draft paper, and checked it in stroke by stroke.

Advanced mathematics is a roadblock that students of science and engineering cannot avoid, and it is also a key factor that determines blue-collar workers in scientific research and white-collar workers in scientific research. It is always good to review earlier.

Calculus represented by Lagrangian, Newton, Leibniz and others was almost established in the 17th century. In other words, college students in 1983 and college students in 2014 learned what mathematicians studied 300 years ago. Yang Rui's advantages in this regard were far less obvious than those in biology.

Fortunately, Yang Rui is still very young and has extremely keen thinking, which makes him unhindered during the review process. Instead, he makes learning advanced mathematics a happy job.
