Black technology starts from the steel suit

Chapter 190 Computational Chemistry 190
"To be honest, it's really not easy to meet everyone." Wang Feng tidied up his body with a lot of wrinkled suits, and then took out a tissue to wipe the sweat on his forehead.

"Everyone is so enthusiastic. The high temperature outside, which is close to 40 degrees, can't stop everyone's enthusiasm for knowledge. Look, I'm so hot." Wang Feng asked people to turn the temperature of the air conditioner to the lowest level, and at the same time opened the door to let the people outside Classmates are a little cool.

Fortunately, Shuimu University has always been very well-funded. Before the founding of the People’s Republic of China, it was supported by Boxer indemnity. After the founding of the People’s Republic of China, it was the only institution of higher learning in the country, so it has been able to keep up with its construction. This is much better than Yan University.

"Teacher, I think it's not just your knowledge that attracts everyone. After all, as a major in cultural media, it has nothing to do with computational chemistry."

"Cough, cough! Everyone, keep a low profile, keep a low profile. The teacher will definitely not be a star. If you want to build our country, you must work hard to build and learn basic cultural knowledge. Those bells and whistles are useless."

"Teacher, you should know that's not what we're talking about, right?"

……

"Okay, okay, let's get down to business. Let's start today's class. Since there are a lot of people today, I won't go into the details. When the next class comes, I hope everyone will bring their classmates who have not come. Since they have signed up, If you are famous, then you have to study hard, and if you fail the final exam, I may not give you more opportunities."

"Since everyone can sit here, I believe everyone must have a certain level. So when the time comes, the questions I give may be a little bit more difficult, so everyone should spend more time when studying of."

"Teacher, are you sure it's a little bit and not a million bit?"

"Okay, let's start today's lesson. Since we are going to talk about computational chemistry, we must first understand its concept. His concept is a branch of theoretical chemistry. The main purpose is to use effective mathematical approximations and computer programs to calculate Molecular properties, such as total energy, dipole moment, quadrupole moment, vibration frequency, reactivity, etc., and used to explain some specific chemical problems."

"Here is a background: Computational chemistry has been developed for many years, and it is in a somewhat awkward position. To put it bluntly-computers are still too weak, and computational chemistry is not accurate when used in practical problems, and the accuracy is not as good as doing experiments. Therefore, whether in the field of chemistry or biology, whether it is a professor or a PhD in computational chemistry, either choose to cooperate with the experimental group, live in the lower reaches of the chain of contempt, or hide in the corner and draw circles in peace."

"So judging from the current situation, computational chemistry is still a subject at a stage of development, and it has not even developed yet."

"Basically, at present, it is the same whether it is domestic or foreign. The reasons have already been mentioned just now. But besides this, there are actually two."

"One is that we still lack the necessary theoretical support and models in this area, that is to say, we are still lacking in theoretical chemistry. The breakthrough of computational chemistry actually depends on the breakthrough of theoretical science."

"The second is that at present, most of the computational chemistry is mainly focused on the application stage, and few people do the theory. Everyone hopes that when doing a specific project, they can use calculations From the perspective of chemistry to provide certain ideas and methods, to provide a little inspiration for myself.”

"Everyone says they want to do this, but there are actually some difficulties, whether it's doing research or getting a job... I can understand this. After all, most people are still ordinary people. We also have to eat and live. Yes, ideals cannot be eaten as food."

"To a certain extent, I agree with other people's views. The domestic situation is that it is more difficult to do computational chemistry alone, unless you can achieve the level of a handsome professor in the school or Fudan Professor Xu - even if this level, They will also often seek cooperation with people in the field of application. In the short term, this kind of cooperation can promote the gradual acceptance of computational and theoretical chemistry in the traditional chemical field, which is beneficial to the development of computational chemistry."

"But in the long run, this will cause some troubles to the research of theoretical chemistry. Of course, I don't have any opinions on others, and I hope you don't spread it indiscriminately."

"By the way, are there any students of Professor Shuai here?" Wang Feng asked.

After a while, several people raised their hands.Then everyone discovered that it wasn't just the seniors who were not doing their jobs properly.Came here to take classes.Even several graduate students are like this...

Sophomore and junior: This is too much!

"Here, I hope that everyone can stick to their hearts, don't be moved by external things, and can persevere and follow their own path. If you have any difficulties, don't hide them in your heart. No matter what difficulties you have , I have to find a teacher to solve it in time. I can’t guarantee anything else, but it’s not a problem to help you solve the problem of eating and find a job that is worthy of your graduate or doctoral status.”

"Although it is unlikely that we will get rich, it is still possible for our family to have enough to eat, a place to live, to meet daily expenses, and then have a little money left over. After all, it is just a part-time job."

Classmate: When did part-time jobs make so much money, why didn’t I know?
"If you need it, you can go to the Beijing Lithium Battery Research Institute to find this person, or you can call this person for consultation. I will arrange it in advance."

"Here I have to mention that many people who study computational chemistry are half-way monks and have not conducted a systematic study of theoretical chemistry. They lack the necessary chemical structure and the basis of quantum chemistry, which has led to these years. Although this subject is continuing to grow, it is only big but not strong."

"One of the main reasons is that many scholars who study theoretical chemistry did not continue to stay in this field, but chose other directions. Do you know why?"

"IT salary is high..."

"By the way, what this student said is not wrong. Because of computational chemistry theory, you need to have a certain programming ability. After all, our human computing power is limited, and we still need to rely on the power of supercomputers in this regard."

"In the process of doing theoretical research, they will occasionally take some part-time jobs. Then they will find a problem. I do experiments, write papers, and publish papers 12 hours a day...I can't earn 1 yuan a month. money."

"And then? I set aside two hours every day to write some programs. This part-time income is much higher than my main income...so everyone can think of the rest."

"Of course, this doesn't mean that my family doesn't love this job anymore. It can only be said that life forces me to. After all, at the age of 30, a man has to support the family, raise children, and take care of his own family."

"If there is no financial support, can't we just let everyone continue to generate electricity?"

"So I can give you a guarantee here. If you find me as a teacher in the future, I will continue to study the theory because I listen to you. But then I found that I couldn't find anything particularly good. Work, okay, you can come to me when the time comes."

"I can tell you about our full-time work, our wages will never be lower than those of those major Internet companies. You can rest assured about this."
