And this time, he was pressing me down and rubbing her.
Liu Yun'er's mood was very low. She didn't want to admit that she was worse than the big idiot in front of her, but in fact, she was worse. He could always solve problems faster than herself, and he solved them perfectly.
"What's wrong with you?" Lin Fan asked with concern on his face when he saw Liu Yun'er's depressed look.
"I"
"You" Liu Yun'er looked at Lin Fan, pursed her lips and said dissatisfiedly: "This is obviously my idea."
"What do I think? They are all the same." Lin Fan breathed a sigh of relief and said with a smile: "By the way, I found another problem: when the hourglass is in quicksand, it shows a trend of first falling and then rising. I tried to solve it from a theoretical perspective
Let’s analyze the reason.”
After hearing what Lin Fan said,
Liu Yun'er swept away all the previous gloom and asked curiously: "What's the reason?"
"Well"
"I calculated the quantitative relationship between the apparent weight of the hourglass system and the changes in parameters such as the initial drop height of the sand and the outlet sand mass flow rate." Lin Fan said seriously: "In fact, the size of the curve has nothing to do with the total mass, but it has nothing to do with the total mass.
It depends on the height of the outflow."
"for example"
"The state of falling after touching the ground is an overweight state, and the apparent weight at this time is greater than the initial weight." Lin Fan paused and continued: "I suspect this may be related to the initial speed when exiting."
Liu Yun'er looked at Lin Fan, looking at the big idiot in front of her who often bullied her. How could this extend to a change in her weight?
"Can you show me your calculation process?" Liu Yun'er asked.
"Um."
Lin Fan nodded, handed his calculation process directly to Liu Yun'er, and then said seriously: "Just take it without asking."
When Liu Yun'er heard these words, a warm current flowed through her heart, and she finally said something human!
After taking Lin Fan's manuscript paper, Liu Yun'er carefully studied Lin Fan's calculation process. She had to say that the whole process was so simple and clear, with almost no flaws. She was convinced that any professor in the Department of Physics at Shennan University would
It is impossible to write down such a calculation process.
This guy first established a relatively systematic mathematical model, analyzed the relationship between the position of the center of mass and time, and calculated the second-order derivative of time to obtain the acceleration, and used the motion of the center of mass to obtain the overall total external force.
but,
This seems to be only half done, not even half done.
Liu Yun'er wanted to know what kind of conclusion Lin Fan could draw by starting from the analytical expression of change, but it was a pity that it ended here.
"No more?" Liu Yun'er raised her head and looked at Lin Fan.
"Um"
"Because the results can only be analyzed through experiments." Lin Fan shrugged and said calmly: "So the theoretical part can only end here."
""
"Do you want to continue?" Liu Yuner asked.
"I don't want to." Lin Fan shook his head: "Too tired."
Liu Yun'er stared at the guy in front of him, helpless. While waiting for the food, this guy used pure theory and mathematics to preliminarily analyze the changes in quicksand weight. This incredible ability is enough to find a top university.
, serves as professor of science.
result
He became a librarian, on a temporary basis.
well
Lin Fan,
You are so difficult to understand!
"Can you give this to me?" Liu Yun'er asked.
"Yeah." Lin Fan nodded. He was playing with the hourglass at this time.
""
"Okay, don't do it!" Liu Yun'er said helplessly: "We all know that as long as you shake the hourglass, you can speed up the hourglass time, but how is it possible to swing the hourglass in public? Are you a blind waiter?"
"I'm thinking"
"How to make the hourglass in a closed space leak faster without relying on external influences." Lin Fan frowned and said seriously.
Liu Yun'er had a dark look on his face and said angrily: "Are you going to die if you don't take advantage? That's almost enough. The food is about to be served. What are you planning to do if we are discovered? It will be very embarrassing, okay?"
"
"What does it mean to take advantage?"
"This is called serious scientific research." Lin Fan said angrily.
Liu Yun'er stopped talking to Lin Fan. Originally, this was just a whim to spend some boring time. He had no intention of taking advantage of other people's restaurants. Even if he really found a way, he wouldn't use it.
Before Lin Fan could find the safest and most reliable way, the dishes he ordered began to arrive on the table. At this time, he also understood a truth, it was all a merchant's routine.
In fact, the hourglass is quite precise. After all, it is a timer device made of physical structure. As for swiping the hourglass to accelerate it,
No one would do this in a restaurant in real life.
but,
The problem of focusing on change can be solved. Although the textbook uses this problem to help understand momentum, the textbook does not consider the up and down movement of the hourglass, so the textbook is flawed.
The conclusion in the textbook is that the apparent weight is equal to the static weight in the steady flow stage. In fact, this conclusion is difficult to establish.
After the two of them finished eating, they went directly to the high-speed rail station, but the train didn't leave for two hours.
Because Liu Yun'er had too little sleep and waited for the bus for too long, a feeling of sleepiness swept over her as she sat.
Unconsciously,
Liu Yun'er's head began to tilt towards Lin Fan's shoulders.
If it were her before, no matter how sleepy she was, she would not let sleep occupy all her consciousness. But when Lin Fan sat next to her, she no longer had the perseverance she had in the past.
at the same time,
Lin Fan was playing a game when his shoulders sank as if something was leaning on him.
I took a glance and found out it was Liu Yun'er.
Without any choice,
Lin Fan silently quit the game. He was afraid that because of playing the game, he would move his arms too much, which would affect Liu Yun'er's rest.
Gently turning his head to the side, he glanced at the sleeping Liu Yun'er. It was the first time he observed her from such a distance. I have to say that her skin was really tender, so tender that you could almost squeeze out the water.
In addition to being tender,
Only beauty remains.
Liu Yun'er's beauty is very natural, without any abruptness. Any small changes will destroy the most direct sense.
At this time,
Lin Fan began to think about his relationship with Liu Yuner.
Quarrels, reconciliations, quarrels, reconciliations seem to keep repeating the same mistakes.
Too,
Wasn't it during this process that I discovered Liu Yun'er earlier than anyone else?
"Why"
"Although I don't know how long the future will be, it may be a lifetime unless something unexpected happens." Lin Fan smiled helplessly and said to himself: "Hey, there is something you have to forgive me for. It's not that I mean to make you angry, it's just that sometimes
I just want to be bad to you, but I can’t help but be bad to you.”
but
an hour later,
Lin Fan had a slight mental breakdown. An hour ago, he thought this might be called a gift, but an hour later, it should be called a suffering.
My neck was sore, my waist started to hurt, and my arms were completely numb.
Become a ruthless sleeping machine.
this
This is more than just annoying.
Oh my God, you should take this big goblin in your arms quickly, and don't let her harm the world again.
Lin Fan wanted to cry but couldn't bear to wake her up.
at this time,
God seemed to sense Lin Fan's request. Liu Yun'er opened her eyes in a daze, and then found that she had fallen asleep on Lin Fan's shoulder. She was so scared that she quickly stepped back and looked at Lin Fan in horror.
"you"
"You didn't do anything excessive, right?" Liu Yun'er asked.
"I want, too."
"But in broad daylight, there are still so many people." Lin Fan said helplessly: "I don't dare even if you give me ten courages. If more than twenty righteous and strong men show up, then I will become an idiom and be covered in sweat."
.”
Liu Yun'er rolled her eyes and wiped the corner of her mouth subconsciously. She found that it was a little wet and quickly looked at Lin Fan's shoulder. As expected, a certain area was very dark in color.
he
He probably didn't notice it, right?
Don't find out, don't find out, otherwise how can you still behave?
"well?"
"Why are you drooling while you sleep?" Lin Fan asked curiously.
Oh my god!
Sure enough, this bastard found out.
Liu Yun'er wished she could find a crack in the ground and crawl in. It was so embarrassing.
But Liu Yun'er is also very strange. He has never drooled while sleeping. Why did it happen this time? It must be because of him.
"It's all your fault!" Liu Yun'er said angrily.
"no"
"I"
Lin Fan looked confused, he had unknowingly become Benzema.
Subsequently,
The two bickered for a while, then sat around in a daze for a while, before embarking on their journey home.
The time from Nanshi to Shenshi is very short, much shorter than the time waiting for the bus.
To Shenshi High-speed Railway Station,
Liu Yun'er glanced at Lin Fan and said calmly: "I'm going home."
"oh."
"I almost forgot that you are from Shenshi." Lin Fan said with a smile: "By the way, why don't you go home to live? Is it because your family always urges you to get married?"
""
"You need to take care of it!" Liu Yun'er pulled her suitcase and headed to the taxi location without looking back.
When Liu Yun'er returned home, it was nearly seven o'clock in the evening, just in time for dinner. Liu Zhongtao and his wife knew that their daughter would be back today, so they prepared a table of meals in advance. Liu Zhongtao's wife, in particular, declined all the banquets.
The person who opened the door was Liu Zhongtao. When he opened the door, his first reaction was not to help his daughter with her luggage, but to look around, as if he was looking for someone.
""
"You came back alone?" Liu Zhongtao asked.
"Um."
"I'm on a business trip alone, so of course I'll come back alone." Liu Yun'er nodded and said calmly, "Dad, help me carry my suitcase."
"Okay, okay."
When the father and daughter walked into the house, a middle-aged woman came out. When she saw Liu Yun'er, she said with a smile on her face: "Daughter is back?"
The words fell,
Like Liu Zhongtao, he looked behind the father and daughter and asked curiously: "You came back alone?"
Liu Yun'er didn't pay attention to her parents' weird behavior. She just nodded and said casually: "Mom, I'm very hungry now. Can you eat first?"
"Hurry up!"
"It has been prepared for a long time."
after,
The family of three sat together and had a sumptuous dinner.
Liu Zhongtao and his wife did not bring the topic to Lin Fan, but simply chatted about home affairs. The couple also knew that this was a critical moment and they should try to avoid embarrassing their daughter, otherwise all their efforts would be in vain.
"I'm going outside to smoke a cigarette." Liu Zhongtao stood up and was about to leave.
At this time,
Liu Yun'er frowned slightly. Thinking of Lin Fan's smoke-filled appearance at the bathroom door that night, she immediately complained a little to her father. He even smoked by himself and took Lin Fan with him. The advantages of that bastard
I didn't have much in the first place, but now I have the disadvantage of smoking more.
"dad!"
"Just wait a moment."
"I need to talk to you right now, in front of mom!"
