After leaving Zheng Xiuhua's place, Gao Fan went to the reference room at the end of the corridor to visit his senior brother Yang Kai.
Inspired by Gao Fan, Yang Kai set his research direction in computational chemistry and decided to start graduate school next semester.
The Department of Chemistry does not teach students in this field at this time, and most teachers don’t even know what this field does.
However, in this era, it is common for graduate students to do their own research. The knowledge structure of many tutors is still more than ten years ago, and they are not as knowledgeable as students about the content being studied abroad.
In this case, graduate students can only choose their own topics and read literature. The role of the tutor is more to provide some guidance on research methods.
This is exactly the case for Yang Kai. The department has assigned him a tutor, but the tutor's own research direction is far from computational chemistry.
Yang Kai graduated from this department and worked as a data clerk in the department for another year. He is very familiar with the teachers in the department. The instructor also knows that Yang Kai is a genius and has excellent self-learning ability, so he has made an agreement with Yang Kai in advance.
In the next three years, he will not interfere with Yang Kai's research, and will only be responsible for helping Yang Kai solve various difficulties in scientific research conditions.
"Old Zhao can't solve any problem."
Facing the junior fellow student who came to visit, Yang Kai laughed and commented on his mentor Zhao Kangwen.
"I told Lao Zhao that in the field of computational chemistry, I don't need test tubes or drugs. I only need a computer. As for the model, I can just use IBM4341. I asked him to apply for one for me. Guess what...
"
"I'm not familiar with Teacher Zhao, but if it were me, my first reaction would be to kick you out." Gao Fan commented with a smile.
An IBM 4341 is worth more than 10 million U.S. dollars, and there is only one in the entire Peking University. After it is equipped with 40 terminals, the computer time is all up for grabs.
Yang Kai actually openly said that he wanted to own one. Isn't this obviously asking for a fight?
"So..." Yang Kai said, "I told Lao Zhao not to worry about my affairs. He is not as useful as my junior brother."
Having said this, he patted the PC on the table, which Gao Fan bought for him with his own money years ago.
"Let's consider this an equal exchange." Gao Fan said, "The cleaning agent formula you calculated for us has improved the decontamination effect by more than 30%. This improved cleaning agent has been sold to Japan, earning us a lot of money.
With the money, I can buy dozens of PCs.”
Yang Kai said: "Many teachers in the department say that you are not doing your job properly, and they also say that the department is making a bad start by allowing you to skip school and go home to start a business. There are also old gentlemen who say that this kind of thing is insulting to politeness."
Gao Fan smiled faintly: "If the school can equip every graduate student with a 4341, then there will be no need for me to do my job."
"Are you really planning to continue like this?" Yang Kai asked.
Gao Fan said: "Let's do this for now. Things on my side have just begun. By the way, I just came back from the United States yesterday. I got a loan of 25 million US dollars in the United States and am preparing to install a vitamin C plant with an annual output of 5,000 tons.
Device.”
"What a great gesture!" Yang Kai sighed.
In this era, information exchange can only rely on letters. Gao Fan and Yang Kai are not lovers, so they naturally will not communicate with each other when nothing happens. Therefore, it was the first time Yang Kai heard about Gao Fan's trip to the United States and his preparations for vitamin C.
"Is there anything you need me to do?"
After sighing, Yang Kai took the initiative to ask.
Gao Fan smiled and said: "I really have some things that I want to trouble my senior brother with. I was just thinking about how to say it."
Yang Kai pretended to be disgusted and said: "How could you still want to deceive me with your little tricks? If you didn't want me to help you, how could you come to me for no reason?"
Gao Fan knew that the other party was joking with him, so he did not answer the question and said seriously:
“The process route for the vitamin C device we plan to build is going to use the two-step fermentation method proposed by the Academy of Sciences.
"I have some ideas of my own when it comes to each process step. If these ideas can be realized, I am confident that the cost can be reduced to less than two-thirds of that of West German Lloyd Pharmaceuticals.
"Currently, I have asked Mr. Hai to take charge of the overall design of the process. In addition, I have hired some engineers from the Maolin Provincial Chemical Design Institute to design various parts of the equipment.
"After all, Teacher Hai is not engaged in this direction. The basic process is okay, but if we want to optimize it on this basis, I am afraid it will be beyond our capabilities."
"You mean, I know the fermentation process?" Yang Kai asked with a smile.
Gao Fan also smiled and said: "I know you don't understand now, but I believe you can understand. The basic process of the entire two-step fermentation method is not difficult. What is difficult is the control of temperature, flow, etc., and this test
It’s math level.”
In later generations, China basically monopolized the global production of vitamin C, relying on continuous optimization of processes, or to use a later term, it was called continuous involution.
Gao Fan remembers the ideas for process optimization, but it is impossible for him to remember the specific parameters such as the size of the fermentation tank, fermentation temperature, and air flow speed. After all, the humanoid database is still a carbon-based organism and does not have silicon-based memory capabilities.
Before he left for the United States, he had sorted out some ideas and gave them to Hai Qingwen and Liao Derong, asking them to make calculations based on these ideas. But the reaction of the two at that time made Gao Fan realize that this matter was very important to them.
Speaking is a big challenge.
When he was in the United States, Gao Fan thought of visiting Yang Kai after returning to China to see if Yang Kai had time to help. As he said, he believed that with Yang Kai's intelligence, it would not be difficult to master the essentials of this craft.
Difficult, subsequent calculations are exactly Yang Kai's specialty.
"Show me the detailed information later. If it is within my ability, I will definitely help you." Yang Kai said.
We are both smart people and we sympathize with each other, so there is no need to make any detours. Yang Kai understands that if Gao Fan had not really encountered difficulties, he would not have come to ask him for help.
"Okay, when I get back to Maolin, I will send you the information." Gao Fan said, "At that time, I might ask you to stay with us for a few days and communicate with our engineers there.
"However, senior brother, I can guarantee that if you come to our Cangtang, you will have enough chicken, duck, fish and meat, as well as Red Army Coke."
"Red Army Coke?" Yang Kai was a little confused.
Gao Fan then told Yang Kai about the allusion between Bob and Red Army Coke. Yang Kai laughed and said: "The curious baby you mentioned is quite interesting. I can't help but want to get in touch with him.
"To tell you the truth, I have been thinking about finding an opportunity to stay in the United States for a while in the future, either to study abroad or to be a visiting scholar. Now there are basically no people in my field in China, so I have to go out and communicate with my colleagues abroad.
one time.
"Get to know your curious baby, maybe it can come in handy in the future."
