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

For biology majors, advanced mathematics is not as important as physical chemistry, but as an interdisciplinary subject, both mathematical physics and chemistry are essential for biological research.

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

If you want to be a blue-collar researcher, you can have a foundation in basic disciplines, and more time can be used in biology itself.

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

Yang Rui is not ready to copy the reality and professional skills in his mind for a lifetime, that kind of life is too boring, rather than this, he might as well make a sum of money to enjoy life.

If you don't have a real level of scientific research, there will be no problems in a short time, but there will be problems in the end. Just as undergraduate students will defend their graduation defense, researchers will also encounter difficulties at various international conferences. If you want to apply for a teaching position, or a title recognized by any country or organization, a defense is essential.

Even Nobel laureates are still hard to avoid real problems. Although it is inevitable that there will be academic skills in the field of science, if there is no strong strength, academic valves will only encounter more challenges.

Just like those large multinational pharmaceutical groups, spend hundreds of millions of dollars every year on various litigation wars, billions of dollars every year on various marketing wars, and tens of billions of dollars every year on various R&D wars, but small and medium-sized pharmaceutical companies will still spring up like mushrooms after a rain and continue to challenge them.

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

On the bright side, the knowledge accumulation of domestic university professors in the 80s is not necessarily as rich as that of master's students 30 years later, and if the backward knowledge is removed, the foreign professors in the 80s are not necessarily much more high-end than Yang Rui.

Everyone can be said to be on a starting line.

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

Any professor or expert who wants to continue to publish papers and write papers needs to keep learning new things, constantly reading new papers and books, and constantly delving into a certain field.

Otherwise, at most two or three years of hard work will be left behind by the rolling forward scientific research army.

Yang Rui is happy to do this, it should be said that he has always loved scientific research life, but some people have the opportunity to do scientific research, and some people do not have such opportunities.

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

During the four years of college, Yang Rui was ready to read some books, not necessarily books in school, but also books that had been saved in his mind for a long time.

As far as the current environment in China is concerned, the school is also the most suitable place to study, and it is difficult to find such a quiet and uplifting environment when you go out of the school.

Yang Rui lay on the bed to learn knowledge and think about life, Wen Xiaoman quietly lay on the top 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 can rest assured and boldly look at the male god without worrying about being discovered by her parents.

This kind of visual enjoyment that is a little exciting and a little happy makes Wen Xiaoman want to stop.

"It's like someone walking down the screen. Wen Xiaoman compared with the teachers in the school while watching.

She studied in the middle school attached to the Central Conservatory of Music, which is difficult to get into, but it is one of the top art majors in China. After graduating, students here can easily be admitted to art universities.

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

Most of the teachers who taught Wen Xiaoman received formal music education, and in the 80s, when popular entertainment was not popular, they were representatives of the forefront of fashion, and there is no doubt that these teachers also did their best to show their distinctive side.

Whether it's handsome, cool, hot...... The teachers of the attached middle school are more eye-catching than the dusty passers-by.

However, compared with Yang Rui, the foundation of the teachers in the attached middle school is too poor, and the fashionable clothes in the 80s are not much better.

The more Wen Xiaoman looked at it, the more fascinated she became, and suddenly regretted that she didn't study art, otherwise, she would have been able to draw Yang Rui now.

"The Boy in the Sleeper Car" may turn into a famous painting.

Wen Xiaoman was crazy when he thought about it.

"What do you want?" Yang Rui suddenly opened his eyes and met Wen Xiaoman.

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

Yang Rui looked up and saw Wen Xiaoman's slender long legs and pure big eyes, and couldn't help laughing: "I don't know what I'm thinking, I'm just in a daze?"

"Who...... In a daze. After Wen Xiaoman finished speaking, he felt that his momentum had been greatly weakened, so he asked: "You go to school, how can you mention so few things?"

"A suitcase, a backpack, a lot. ”

"I see that other students have to carry a lot of things to school, and the closer they are to school, the more so. Wen Xiaoman finally said that it was smooth.

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

"Do you have a car to sit on, or a soft sleeper? "The girl seems to be holding unevenly, and the current hard seat is in an airtight state, which is even more rare for a soft sleeper.

Yang Rui also smiled: "Didn't you also sit on a soft sleeper?"

"I ...... Just sat down this once. The girl's voice was small, but her mood gradually became beautiful, she looked at Yang Rui again with her eyes, and asked, "Are you listening to Walkman?"

"Yes, you know the Walkman?"

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

"I bought it myself. ”

"It's expensive, isn't it?"

"It's not cheap, I bought it with the manuscript fee. Yang Rui was ready to use this excuse for a long time.

"What did you write?"

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

"It's amazing. Wen Xiaoman gave a satisfying exclamation, any male animal, hearing such praise, the muscles of the whole body will tense.

Wen Xiaoman did not doubt Yang Rui. The other party is a student of Peking University, in this case, it is natural to be able to get a manuscript fee for publishing articles.

is handsome and handsome, and he was admitted to Peking University, and he can write articles to earn manuscript fees, Wen Xiaoman feels 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 conservatory, there is no such handsome and stylish boy.

Wen Xiaoman didn't even think about how many words to write in order to earn a Walkman, she looked at Yang Rui with great admiration, and said: "It would be nice if I could also write articles, 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 girls, Yang Rui generously took out his Walkman, put together a few tapes, and handed it to her.

Wen Xiaoman leaned over to reach it, his stretched body showed a beautiful curve, and the fingers of the two gently touched each other.

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

Wen Xiaoman flexed his fingers unconsciously, it was too late to regret it.

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

The melodious singing voice flows out like spring water, which is beautiful and intoxicating.

With a clear singing voice in his ears and a handsome male god in his eyes, Wen Xiaoman's comfortable eyes narrowed.

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

High mathematics is an obstacle that science and engineering students can't avoid, and it is also a key factor in determining the blue-collar and white-collar scientific research.

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

Fortunately, Yang Rui is still very young now, and his thinking is also extremely sharp, which makes him unhindered in the process of review, but makes learning high mathematics a happy job.
