I just want to be a salted fish quietly Chapter 106

Character name suggestions: (Lin Xian), (Zhuang Tong), (Nie Qingqing), (Dai Pingbo)

Taking Lin Xian’s shoulder bag, Zhuang Tong, like a little wife, asked considerately, “What fruit do you want to eat? I’ll peel it for you.”

“No need, I’ll do some problems for a while, you go play!”

Lin Xian was very satisfied with Zhuang Tong’s attitude, and gently pinched her pretty face.

“Mmm!”

Zhuang Tong let out a soft cry, pecked him on the face, and then returned to the hanging basket, snuggling with Nie Qingqing to watch a web drama.

Their personalities were similar; if no one was with her, Zhuang Tong could watch web dramas or do other things all day long at home by herself, and there was no need to worry about her getting bored.

This was one of the reasons Lin Xian agreed to her being his lover.

Many mistresses who were kept, after living a life free from financial worries and losing their goals, would become empty and lonely inside. Plus, since they were mistresses, the other party couldn’t be with them every day, so many mistresses would go out looking for excitement, messing around behind their sugar daddy’s back.

But Zhuang Tong was different; her personality dictated that she wouldn’t feel empty or lonely.

Just like Lin Xian, there were so many interesting things in the world, and life was too short.

Taking out paper and pen, Lin Xian settled his mind and began to ponder how to solve this problem.

At first glance, this problem would make people feel completely at a loss.

This was a typical manifestation of mathematical modeling.

It required strong logical ability to propose a model hypothesis, and then use mathematical language and text to gradually fill in this hypothesis. Finally, after analysis and verification, a correct set of models would be derived.

Moreover, the most interesting point about mathematical modeling was that there was no so-called standard answer.

For example, using mathematical modeling to create a folding chair, different people would create folding chairs with different shapes.

Although the shapes were different, as long as it could be used, you couldn’t say his mathematical model was wrong.

However, there was no standard answer, but there was a distinction between good and bad.

If someone designed a folding chair that was more comfortable and easier to carry, it meant his modeling was more outstanding.

Similarly, the problem given by Dai Pingbo was the same.

Looking at the problem on the paper, Lin Xian’s brain operated rapidly, and the mathematical knowledge he had learned before constantly flashed through his mind.

After pondering for a while, Lin Xian suddenly had an inspiration.

The essence of this problem was actually to study the law of how the speed of an object falling changes with time.

It belonged to the Newtonian mechanics system and could be attempted to build a model using partial differential equations.

Once the model was established, the next step was a series of verifications and proofs.

Thinking of this, Lin Xian couldn’t help but curl his lips into a smile, and his pen quickly wrote lines of numbers on the paper.

Let: T be the echo time, G be the acceleration due to gravity… H be the depth of the deep hole.

Solution ( 1): From Galileo’s law of falling bodies, it is known that…

…

Unconsciously, an hour passed.

Zhuang Tong glanced at the time, stretched lazily and said, “It’s getting late, it’s almost time to make dinner!”

“There seems to be no vegetables in the fridge,” Nie Qingqing said.

“It’s fine, we can just go to the supermarket to buy some.”

Zhuang Tong jumped off the hanging basket and said to Lin Xian, “Honey, what do you want to eat tonight?”

However, Lin Xian didn’t answer, still lowering his head, writing furiously.

“What kind of problem is he doing so intently?”

Nie Qingqing mumbled, walked over and took a look.

What met her eyes were dense numbers and symbols, and lines of calculation formulas that made her dizzy.

Who could handle this?

Excuse me, goodbye!

Zhuang Tong couldn’t help but gasp, “I completely don’t understand, I’d better go cook!”

At this moment, Lin Xian looked up and smiled, “Whatever, you can make anything.”

“Then we’ll go buy groceries!” Zhuang Tong said with a smile.

“Go ahead!”

With that, Lin Xian lowered his head again.

Once he found inspiration, the subsequent calculation formulas seemed to flow naturally. This feeling was simply too exhilarating, making him indulge in it.

…

Sitting in the Beetle, Nie Qingqing fastened her seatbelt and said, “Lin Xian feels so strange!”

“How is he strange?” Zhuang Tong asked with a smile.

“It’s just that he feels completely different from other rich second-generations. I really can’t imagine that he actually sat there and did math problems for over an hour,” Nie Qingqing said with emotion.

Zhuang Tong held the steering wheel and carefully observed her.

Nie Qingqing felt a little unnerved by her gaze and couldn’t help but raise an eyebrow, “What’s wrong?”

“Hehe, I’m thinking we might really be best friends for life!” Zhuang Tong said with a meaningful smile.

Nie Qingqing pretended to be calm and said, “We… we already agreed to be best friends for life!”

“Hehe!”

Zhuang Tong chuckled, not exposing her.

As a woman, how could she not know that when a woman develops interest in a man, it means she’s not far from falling in love with him?

And a man like Lin Xian was like a black hole; attracting women was the most normal thing.

The two girls went to the supermarket to buy groceries. When they returned home, Lin Xian was still doing problems with his head down.

Seeing this, Zhuang Tong tiptoed into the kitchen with the ingredients, trying not to disturb him.

Seven in the evening.

Lin Xian looked up, put down the pen in his hand, and let out a long sigh.

“Done!”

Looking at the dense mathematical models on three or four pages of white paper, Lin Xian felt an unparalleled sense of accomplishment.

According to the problem requirements, he had built a total of four models, and after verification and analysis, he proved that the logic was self-consistent.

Finally, he just needed to import all these mathematical models into a computer and use C++ or MATLAB to find the results of the equations.

To be honest, this problem was his current limit.

For mathematical modeling, basic mathematics was the key to opening the treasure trove. The more keys one mastered, the greater the chance of opening the treasure trove’s door.

“I still need to keep learning!” Lin Xian sighed.

Just then, the system prompt in his brain suddenly rang.

“Ding~”

“Congratulations, Host, for solving the problem, triggering a hidden mission: Heart of the Champion!”

[Heart of the Champion]

Mission Requirement: Participate in the Gaoshe Cup National College Student Mathematical Modeling Contest.

Mission Progress: 0%

Mission Reward: ??? (Final reward will depend on the Host’s performance in the contest!)

…

Holy cow, this can also trigger a mission?

And, isn’t this mission a bit too difficult?

The Gaoshe Cup!

It’s a national college student competition, with a large number of participants from 985 and 211 universities, and even strong math departments like QHBD, FD, and TJ. It’s really hard to get a good ranking.

Not to mention distant ones, even the math department of Jin University next door completely blows Jin Cai out of the water.
