Lin Fan couldn't wait to turn on his computer, and then logged into his game account to start his hero's journey in the world of Azeroth. He took a look at the list of guild members and found that the number of people online in the guild tonight was reduced by nearly half.
Too...
Sister Liu, who is across the street, gave her student a difficult problem. She is probably worried about solving the problem now, so she doesn't have time to play games.
Without any choice,
Lin Fan gave up the idea of playing a dungeon, rode his mount to the platoon battlefield, and started playing PVP.
At this time,
He found that a familiar name was online, that was Liang Xuchao, the second- and fifth-year-old boy.
Handsome Guy Cat: Is it solved?
Someone on the beam: No...forget it, give up.
Handsome guy Maomao: Are you giving up now? No longer insisting?
Someone on the beam said: No matter how hard I persist, I won’t be able to do it.
Looking at the message that Liang Xuchao replied, I couldn't help but frown. To be honest, this foundation... is indeed very poor. The question Liu Yun'er gave is so simple. An electron is in a one-dimensional infinitely deep square potential with width x=
The n=1 eigenstate of the well is in the uniform electric field in the x direction when t=0.
Use time-dependent perturbation theory to calculate the probability that the electron is at n=2 and n=3 respectively when t is greater than T, and then give a reasonable parameter.
What's so difficult about this?
According to the absence of an electric field, the potential function and energy eigenstate of the electron are obtained, and then the calculations are carried out... Is it so difficult?
Lin Fan sometimes doesn't understand how people like Liang Xuchao think about physics issues in this way, as if physics is particularly difficult in their eyes. In fact... many theories can be deduced from a basic concept.
perhaps,
They are just forced to enter the physics department without any love for physics. Under this premise...it is difficult to make a breakthrough, and they lack any talent.
Thinking of this,
Lin Fan sighed. This world is similar to his own. Lin Fan once taught many Ph.D.s, but most of them did not go into the field of scientific research. They just wanted a status that could improve their status, because doing scientific research was very poor.
...are really poor, and the problem happens to be society as a whole.
The desire for wealth and fame far exceeds the pursuit of science and technology. The worship of science and scientists has long been eliminated in society. What is even more sad is that... most people default to doing scientific research and should stay in poverty.
Thinking of this,
Lin Fan sighed. He used to worry about these things, but he still worries about these things now.
Sudden,
There was a knock on the door, followed by Liu Yun'er's voice.
"Open the door!"
Lin Fan was stunned for a moment, and he also ate the meal with her. Why did he come to see him this late at night? Can he have some private space?
Without any choice,
Lin Fan silently stood up and opened the door for her.
The moment he opened the door, Lin Fan saw Liu Yun'er in front of him and completely lost all thoughts. Only his physiological functions were still running, such as...the simplest breathing. At this moment...he
It was like being struck by lightning, and he was stunned in place.
this...
Who is this?
Has the fairy from heaven descended to earth?
Her clear and bright pupils, curved willow eyebrows, eyelashes are trembling slightly, her thin lips are as delicate as rose petals, and her flawless white skin reveals a faint red pink, telling others all the time that this is the time when she has fallen into the mortal world.
of fairies.
This dress, in particular, gives the fairy a touch of solemnity and composure. Her elegant temperament, peerless appearance, and arrogant figure are simply dizzying.
At this time,
Liu Yun'er was particularly satisfied when she saw the demented Lin Fan... This meant that even this bastard couldn't stop the charm she released after putting on this dress.
"Hello!"
Liu Yun'er turned her head to the side and asked calmly: "Is it tender?"
After hearing Liu Yun'er's words, Lin Fan finally came to his senses. At this moment, he couldn't figure out the inner world of the woman in front of him. Is it necessary to make such a big show? Just to prove whether he is young or not? What can he do if he is young?
But there is one saying,
The thief is so tender!
certainly,
Lin Fan didn't want to tell her his truest thoughts, lest she become arrogant towards him in the future. In this case...how to answer her gracefully? At the same time, it would not hurt her arrogant character.
After thinking about it for a moment,
Calm analysis,
He wanted to speak but stopped.
Lin Fan said seriously: "You wear a little too much."
Suddenly,
The whole atmosphere changed. Liu Yun'er, who was still pretending to be calm at first, instantly became covered with red clouds after hearing Lin Fan's words. The red clouds were slowly attacking her neck, and a wave of red clouds spread across her face.
Anger mixed with shame rushed directly to the brain.
after,
All Liu Yun'er's sanity was washed away.
I...
Am I crazy?
She actually wore such nice clothes to show him.
But I showed it to him... and at least gave it a compliment, right? As a result... the reply I got was... such vulgar words.
ah!!!
Why?
Why did God let me know this bastard?
“Quite pretty.”
"Actually, if you are beautiful, you will look good no matter what you wear." Lin Fan said with a smile: "How much did it cost?"
Liu Yun'er was stunned for a moment and glanced at Lin Fan, who was smiling. This sentence was barely human.
"More than three thousand." Liu Yuner said calmly, still tilting his face.
"What?"
"More than three thousand?" Lin Fan said in surprise: "Are you crazy?"
"right!"
"I'm mad!"
"What can you do to me?" Liu Yun'er was so angry that he was half-dead. More than three thousand... wasn't just for... Anyway, he was crazy, completely crazy.
I don’t know why Liu Yun’er is so angry. From Lin Fan’s understanding... buying a dress for more than 3,000 yuan is just because people are stupid and have too much money. Is this fabric special?
After thinking about it,
Lin Fan reached out to touch Liu Yun'er's dress. He wanted to experience for himself what was so special about these three thousand pieces of fabric.
"you..."
"What are you doing?!" Liu Yun'er saw Lin Fan stretching out his pig's hoof. She was so frightened that she took a few steps back and said angrily: "I'm not that kind of... frivolous woman.
"
"..."
"what are you thinking?"
"I'll just feel the texture of three thousand pieces of fabric." Lin Fan said helplessly: "I'm really not the kind of person you think."
"snort!"
"Who knows." Liu Yun'er said angrily, "You can only touch it."
"Um..."
after,
Liu Yun'er walked up to Lin Fan and lifted up a corner of her skirt. This gesture was telling Lin Fan to come up and touch it.
Lin Fan did not hesitate, stretched out his big pig's hoof again, and touched the skirt worth more than three thousand.
Well?
Very familiar,
This texture seems familiar!
suddenly,
Lin Fan suddenly realized it and said to Liu Yun'er: "Isn't this just my tablecloth?"
