Sail across the sea

Coming out of Zheng Xiuhua, Gao Fan went to the reference room at the end of the corridor to visit his brother Yang Kai.

Inspired by Gao Fan, Yang Kai set his research direction on computational chemistry, and decided to start a postgraduate study in the next semester.

At this time, the Department of Chemistry does not teach this direction, and most teachers don't even know what this direction is.

However, in this day and age, 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 familiar with the content of research abroad as students.

In this case, graduate students can only select topics and read literature by themselves, and the role of the tutor is more to give some guidance on research methods.

This is exactly the case with Yang Kai.The department has designated a supervisor for him, but the research direction of this supervisor is far from computational chemistry.

Yang Kai graduated from this department, and worked as a data officer in the department for another year, and is very familiar with the teachers in the department.The tutor also knew that Yang Kai was a genius with excellent self-learning ability, so he had made an agreement with Yang Kai in advance that he would not interfere with Yang Kai's research in the next three years, and was only responsible for helping Yang Kai solve various difficulties in scientific research conditions.

"Old Zhao can't solve any difficulties."

Facing the junior juniors who came to visit, Yang Kai commented on his mentor Zhao Kangwen with a smile.

"I told Lao Zhao that I don't need test tubes or medicines for my field of computational chemistry. I just need a computer. The model is just a so-so IBM4341. Let him apply for one for me. Guess what... "

"I'm not familiar with Mr. Zhao, but if it were me, my first reaction would be to kick you out." Gao Fan commented with a smile.

One IBM4341 is worth more than 1000 million US dollars, and there is only one in the entire Peking University. After it is equipped with 40 terminals, the machine time is to be grabbed.

Yang Kai actually brazenly said that he wanted to own one, isn't this obviously looking for a fight?

"So..." Yang Kai said, "I told Lao Zhao, don't worry about my affairs, he is not as useful as my junior brother."

Having said that, he patted the PC on the table, which was bought by Gao Fan himself and given to him years ago.

"This is an equivalent exchange." Gao Fan said, "The cleaning agent formula you calculated for us has improved the decontamination effect by more than [-]%. This improved cleaning agent has been sold to Japan and earned us a lot of money." With enough money, you can buy dozens of PCs.”

Yang Kai said: "Many teachers in the department said that you are not doing your job properly. They also said that it was a bad start for the department to allow you to go home without studying and start a business. There are also old gentlemen who say that such things are degrading."

Gao Fan smiled lightly: "If the school can equip every graduate student with a 4341, naturally there is no need for me to not work properly."

"Are you really planning to go on like this?" Yang Kai asked.

Gao Fan said: "Let's do this for now. My business has just started. By the way, I just came back from the United States yesterday and got a loan of 2500 million US dollars in the United States. I am going to install a set of vitamin C with an annual output of 5000 tons device."

"What a great handwriting!" Yang Kai sighed.

In this day and age, information exchange can only be done by writing letters. Gao Fan and Yang Kai are not lovers, so naturally they can’t communicate without incident. Therefore, Yang Kai heard about Gao Fan’s going to the United States and planning to engage in vitamin C for the first time.

"Is there anything I need to do?"

After sighing, Yang Kai took the initiative to ask.

Gao Fan laughed and said, "I really want to bother senior brother with something, and I was still thinking about how to speak up just now."

Yang Kai pretended to be disgusted, and said: "You are so thoughtful, you still want to deceive me? 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 didn't pick up the conversation, but said seriously:
"The vitamin C device we plan to build, the process route is going to use the two-step fermentation method proposed by the Academy of Sciences.

"Specifically for each process link, I have some ideas of my own. If these ideas can be realized, I am sure that the cost will be lowered to less than two-thirds of that of West Germany.

"At present, I invite Mr. Hai to be responsible for the overall design of the process. In addition, I hired some engineers from the Maolin Provincial Chemical Design Institute to design various parts of the equipment.

"Mr. Hai is not in this direction after all. The basic craftsmanship is fine, but if we want to optimize it on this basis, I'm afraid it will be beyond our capabilities."

"You mean, I understand 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 whole two-step fermentation method is not difficult, the difficulty is the control of temperature, flow, etc., and this test It's the math level."

Later generations of China basically monopolized the global production of vitamin C, relying on the continuous optimization of technology, or to use a later term, it is called continuous involution.

Gao Fan remembered the ideas for process optimization, but it was impossible for him to remember specific parameters such as the size of the fermenter, fermentation temperature, and air velocity.Humanoid databases are still carbon-based organisms after all, without the memory ability of silicon-based.

Before he set off for the United States, he had sorted out some ideas and handed them over to Hai Qingwen and Liao Derong to make calculations based on these ideas.But the reaction of the two at the time made Gao Fan realize that this matter was a big challenge for them.

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 believes that with Yang Kai's intelligence, it is not difficult to master the essentials of this craft, and the follow-up calculation is just Yang Kai's specialty.

"Show me the detailed information later. If it is within my ability, I will definitely help you with this job." Yang Kai said.

They are both smart people, and they cherish each other, so there is no need to make any detours.Yang Kai understood that if Gao Fan hadn't really encountered difficulties, he wouldn't have come to beg him for help.

"Okay, I'll send you the information when I get back to Maolin." Gao Fan said, "When the time comes, I might invite you to stay with us for a few days and communicate with our engineers.

"However, brother, I can guarantee that if you go to our Cangtang, you will have enough chicken, duck and fish, as well as Red Army Coke."

"Red Army Coke?" Yang Kai was a little puzzled.

Gao Fan then told Yang Kai the allusion about Bob and the Red Army Coke, and Yang Kai laughed and said, "The curious baby you mentioned is quite interesting, I can't help but want to touch it.

"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, whether it is to study abroad or to be a visiting scholar. Now there are basically no people in China who are in my direction. I have to go out and communicate with colleagues abroad. one time.

"Get to know your curious baby, maybe it will come in handy in the future."
