Qin Ze looked in from the door. This classroom was no different from an ordinary classroom. The only difference was that the desks and chairs had been moved to the back of the classroom, leaving only four or five desks with notebooks on them. The students sitting at the desks either looked up or focused on their own work. Professor Li was in his fifties. He had white hair, slanted eyebrows, and a pair of old-fashioned round-rimmed glasses. He looked like a very serious and difficult old scholar.
He looked away from the computer and turned his head, "Come in."
Qin Ze nodded and walked to the podium.
Professor Li pushed up his glasses and looked at Qin Ze, "You are in your third year of university, right? You will be doing your internship in the second half of next year."
"Yes, that's why I want to train myself in advance." After Qin Ze finished speaking, he suddenly realized that he wasn't nervous at all. According to his usual character, he should have been a bit cautious when being scrutinized by the professor's sharp eyes. However, he was very calm. He was so calm that even he was surprised by himself.
Professor Li nodded, "Although your father has told me about this, let's talk about it as it is. There should be a lot of tests."
He took out a stack of A4 paper from the drawer. There were many problems listed on it. He picked out a few papers and handed them to Qin Ze, "This is a small part of the problems in mathematical modelling. It is relatively easy. Take it and have a look. I will give you two hours. You can pick any two problems and deduce the analytical equations. Xiao Liu, give him a pen. "
The female student who opened the door immediately handed a pen to him.
Qin Ze didn't speak any nonsense. He looked around and found that there weren't any extra seats, so he went to the back of the classroom and pulled out a desk on his own. He moved quietly, trying not to make too much noise.
Qin Ze threw himself on the draft paper to deduce the equations. He looked at the topic from time to time. There were several times when he was about to deduce the complete equation, but he had to start over again.
Mathematical modelling was a very profound subject. What he was doing now could not even be considered a mathematical modelling. It was just a small step in a long journey. Mathematical modeling was also known as mathematical modeling. In essence, it was an important means to use mathematical tools to solve practical problems. In layman terms, it was to use mathematical language and methods to establish "equations" for certain things and phenomena. For example, if a mathematician wanted to predict the weather, he could collect data and build a huge mathematical model. Through the mathematical model, he could calculate the weather the next day.
Of course, this was just a metaphor. The real weather prediction was far more complicated than this. But in fact, the weather bureau was a huge mathematical model.
Economics and mathematics were inseparable. Mathematical modelling was also a very high-end and widespread application of it.
Qin Ze calculated for half an hour, his forehead gradually sweating, and finally felt the right direction. Or was it because his foundation in mathematics was too shallow? He had to rack his brains to think of many formulas. If Qin Bao Bao were here, she would definitely snort twice, push Qin Ze's head and say, "Get out of my way, I'll take care of it in minutes."
It was said that men were born logical and women were born emotional. Therefore, men were good at science and women were good at liberal arts. However, this rule was completely reversed when it came to the Qin siblings. Qin Bao Bao was a top student in mathematics since she was a child. Her grades had never dropped out of the top three. She called herself the queen of science. Qin Ze was better at liberal arts. His most glorious achievement was winning the third prize in the National Middle School Essay Competition.
Fortunately, he knew that he was not a smart person and that hard work could make up for it. He did not give up and was not stumped by the two questions that could block 50% of the students.
Time flew by. With the help of his assistants, Professor Li pushed the modeling progress bit by bit. From time to time, he would have small meetings. However, these had nothing to do with Qin Ze.
Two hours later, Professor Li seemed to remember Qin Ze. He walked down from the podium and came to his desk. Without saying anything, he picked up his paper and looked at it. The answers to the equations were written neatly on the white paper. Professor Li liked the meticulousness at first sight. He looked at the draft paper and scribbled on it. The dense calculation formulas were not left out at all. Qin Ze's mathematics was trained by his grandfather.
"Not bad!" Professor Li nodded and put the paper back on the table. He turned and walked back to the podium. "Stop what you are doing."
Five or six assistants raised their heads.
"Let me introduce a new member to everyone. He is Qin Ze from the Finance Department's Class 7. He is your junior."
Qin Ze stood up and said politely, "Please take care of me."
There was sparse applause.
Professor Li said again, "Yang Chen, you will teach your junior for the next few days. Let him figure out our project this morning. I have a class later, so I will leave first. "
A boy in a blue T-shirt and white casual pants nodded and smiled. "Got it, professor."
Professor Li left.
Before coming here, his grandfather had told Qin Ze in detail that it was a huge mathematical model. It was impossible for Professor Li to do everything himself. Therefore, he needed assistants. The assistant's salary was 200 yuan per day for a week. After the mathematical model was completed, he would get 1,400 yuan.
Professor Li was not willing to recruit students. Several of his assistants were fourth-year interns who would graduate next month. Because of his grandfather, he agreed to let Qin Ze give it a try.
Qin Ze waited for a moment in his seat. When he saw Yang Chen working, he took the initiative to walk over and said, "Senior."
Yang Chen looked at him and took out a stack of documents from the drawer. He said, "Take a look at it yourself."
Qin Ze took the documents and went back to his seat. He patiently read them. A good private equity company should have its own professional market analysts. It could be seen that the private equity company that commissioned Professor Li was not large. To build a complete mathematical model, it required a lot of formulas and data. Mathematics was the most rational thing in the world. Every step needed to be carefully considered. Qin Ze's group was responsible for the return and risk assessment.
In addition to the not too detailed summary, there was a series of symbols and explanations. Qin Ze looked a little tired. He took out his phone, searched the Internet, and translated them one by one.
In the blink of an eye, it was time to eat. The seniors in the classroom went to the cafeteria to solve the problem of food and clothing. Qin Ze wanted to take out his spirit and immerse himself in studying, but he was kicked out by the senior who was in charge of the key to eat.
Because time was limited, he ate a little and hurried back to the classroom.
The classroom door was ajar, revealing a gap. Just as he was about to push the door open, he heard someone say, "Brother Chen, what's the new guy's background? We worked hard for a month to build this mathematical model. There's only a week left before the delivery time. Good lord, he suddenly jumped in and earned our labor costs. "
The guy who spoke was also in Qin Ze's group. Qin Ze did not know his name.
Yang Chen snorted. "His dad and Professor Li seem to be in the same office. He's a relative, so he came to learn and get some pocket money."
"Our group only has a bonus of 10,000 yuan. He took more than 1,000 yuan. Motherf * cker, it's enough for half a month's rent."
"Don't you still live in the dormitory?"
"Then you can come to the health care twice."
"Don't worry, there's a task today. He doesn't even know the basic situation. When the time comes, I'll assign some tasks to him. If he can't complete them, hehe, Professor Li will definitely not be happy. If he comes a few more times, maybe he'll be kicked out. "
Qin Ze's face turned black. He thought to himself, "These two little bastards." He silently went downstairs and strolled around the teaching building. He sighed in his heart. Sure enough, where there were people, there was Jianghu. This kind of fighting without swords became more and more cruel after going to college. No, there were fights everywhere in life. Elementary and middle school were no exception. It was just that at that time, he was young and liked to express it in violent ways.
Qin Ze did not like this kind of hidden in the dark and extremely sinister intrigue. He had not adapted to it yet.
Ten minutes later, he went upstairs into the classroom. The seniors were basically back. The senior named "Xiao Liu" smiled at him. Qin Ze politely returned a smile.
There was a professional class at 1: 30 in the afternoon. After class, Qin Ze refused his roommate's invitation to go online and play games. He plunged into the modeling data pile. Although he was not a gifted science expert like Qin Bao, he had one advantage that the old man praised: Every time there was a big event, he was calm! This was the old man's praise for him.
At five o 'clock in the afternoon, Professor Li came back. Each group was assigned tasks. Before announcing the end of the day, he rarely thought of Qin Ze.
"How's the information on the return rate and risk assessment coming along?"
"I'm a person blindly guessing. I haven't fully grasped it yet." Qin Ze said.
Professor Li suddenly frowned and looked at him. "Didn't I ask you to bring him along?"
Yang Chen looked innocent: "I gave him the information and let him ask me what he didn't understand, but he didn't have any problems all day. I thought that Qin Ze had a thick foundation and had mastered it by himself."
F * ck, when did you say that?
Professor Li looked at Qin Ze and didn't say anything. He announced the end of the day's work. Professor Li's carefree attitude made Yang Chen somewhat disappointed. Only Qin Ze could vaguely guess his thoughts. In fact, the modeling was nearing the end. It was true that they lacked an assistant. But how could they invite a half-baked Qin Ze to join them? It was mostly for the sake of the old man. That day, the old man also vaguely said that if there was anything he didn't understand, he could ask him.
So whether Qin Ze was idling around or not, Professor Li didn't care. His father was helping behind the scenes.
Qin Ze asked Yang Chen for the information. He didn't refuse and gave him a stack of copies. How could a college student see flowers just by looking at the information?
After the team disbanded, it was still early. He said in the chat group, "Liberated!"
After a while, Li Liang replied, "Come quickly, we need you to preside over the overall situation. Damn, you can't lead them."
Zhao Baliang followed and replied, "I can't lead you. I fought one against three and vowed not to retreat. When I turned back, damn, where are my teammates? They all died and returned to the hot springs. "
Then Liu Ziqiang replied, "I'll quietly watch you guys act cool. I won't say anything."
Qin Ze's mouth hooked up. He put his phone back in his pocket, carried his shoulder bag, and trotted towards the direction of the internet cafe.
It was a familiar position and three familiar animals. With a cigarette in his mouth, he leaned against the sofa. Because he was waiting for Qin Ze, Li Liang took the time to watch the competition videos. Zhao Baliang opened a small window to watch the Japanese president Liu Ziqiang play with his phone.
Qin Ze habitually put a cigarette in his mouth, turned on his phone, and squinted his eyes to smoke.
"It's summer vacation at the end of the month. What are you doing? Be careful not to fail. "Li Liang took a deep drag on his cigarette.
"I can't let my sister support me all the time to earn some pocket money." Qin Ze took out mineral water from his bag and gave a bottle to each of them.
"Investment modeling is not easy. There are too many factors to consider. How do you feel on the first day?" Liu Ziqiang, who had the best results compared to the other two, unscrewed the cap and took a sip.
"It doesn't matter if it's difficult or not. I'm just not in a good mood because I met a b * tch today." Qin Ze complained.
"You have a story, but I don't have any alcohol. Tell me about it. "Li Liang invited Qin Ze to join the game.
"He's just an idiot. I'll find a chance to deal with him." Qin Ze curled his lips.
"When the time comes, bring Ba Liang and use his Human Cannon to poke that idiot's ass." Li Liang had just finished his sentence when he suddenly shouted, "Are you crazy? Why did you invite a newbie?"
A person with the ID "Canton Waist" sneaked into the team. She was the bronze noob B who had tricked them the other day.
Canton Waist enthusiastically said in the room, "Hooray, hooray! Guru, you're finally online."
"Guru, are you guys playing a game?"
"I've lost three rounds in a row today. I've lost again."
"Guru, bring me up and let me fly. I'll video call you."
The three animals didn't want to talk to her. Even Zhao Baliang, who lacked love, didn't want to talk to her. These days, there were too many transvestites on the Internet. She felt disgusted when she thought of the man on the other side of the screen.
Qin Ze playfully replied, "Do you want to chat naked?"
"I hate you!"
The screen darkened and she entered the game.
