Chapter 2 Not only escape, but also defraud!

at this moment,

Lin Fan was confused. He didn't know if this was a coincidence. In short... he was in big trouble!

The woman with the refrigerator face also noticed something strange and stepped towards Lin Fan.

Seeing the unreasonable refrigerator-faced woman getting closer and closer, Lin Fan instinctively shrank his head. Although all this has become a foregone conclusion, it's lovely... Only when you have dreams can you have the motivation to move forward. Maybe this is

What about misunderstanding?

The woman with a refrigerator face sat directly opposite Lin Fan and said expressionlessly: "Are you Lin Fan?"

"ah?"

Lin Fan said cautiously: "Girl... you may have mistaken the person. My name is... Lin Jinfan, my name is not Lin Fan."

The woman with the refrigerator face glanced at Lin Fan and said calmly: "My name is Liu Yun'er. Next, let's go through a process. Order food, eat, pay AA, and leave. Let's start the process now."

At this moment, Lin Fan's scalp was numb. What kind of thing had he encountered? He was like a robot with no emotions.

After that, Lin Fan ordered a steak, and the woman with the refrigerator face ordered a spaghetti bolognese. The two ate their lunch in silence. Lin Fan wanted to ask each other's basic conditions several times, but in the end he couldn't.

I held it back, this face is too scary!

actually...

Seriously,

Liu Yun'er is very beautiful, but unfortunately she is too aloof and cold, so cold that she can't get close to her.

well?

Her surname is Liu? The curator is also surnamed Liu? Could it be related?

At this time,

Liu Yun'er took out a notepad and a pen from her bag, and then put them aside. While she was eating spaghetti bolognese, she was writing something unknown with the pen.

Lin Fan was quite curious. He cautiously stretched his head and took a look. He felt that this was a problem about scattering in quantum mechanics.

actually,

This question is very simple. As a top genius who has won the Nobel Prize in Physics in the past, he can understand it at a glance with his peripheral vision. He can directly use the scattering amplitude calculation formula, or use the Gaussian integral formula to get the same differential scattering cross section.

But what makes Lin Fan curious is...what does the woman with the refrigerator face do? Why is the scattering problem in computational quantum mechanics?

It seems that his education level is not low!

less than five minutes,

Liu Yun'er calculated the final value. When she was about to close the notepad, she found that the man in front of her had been staring at her notepad, with his brows furrowed, as if he was thinking about something.

"You seem...wrong!" Lin Fan suddenly said something.

"..."

"What did you say?" Liu Yun'er was stunned for a moment, with a slightly surprised expression on his face, but soon returned to normal and asked, "You said I was wrong?"

"Um!"

"You seem to have made a mistake in your calculations." Lin Fan smiled bitterly and said, "Will you check again?"

Liu Yun'er looked at Lin Fan, looked at the man carefully, and asked seriously: "Do you know what I am doing?"

this...

This is not a study of the atomic bomb, making it look like the real thing.

"Isn't it just a problem of using adiabatic approximation to calculate the scattering cross section of particles in V=Ae^(-r^2/a^2)." Lin Fan said angrily: "A particle with mass m is repelling

When moving in the potential V=Ae^(-r^2/a^2), use the adiabatic approximation to calculate the differential scattering cross section and determine a multiplication constant."

Hearing these words,

Liu Yun'er was stunned for several seconds. When she came to her senses, she found that the man in front of her was cutting her own steak. At this moment, Liu Yun'er wondered if she had just hallucinated.

He reopened his notepad and looked at the calculation process above again. This time Liu Yun'er was extra careful, and the result... was exactly what the man in front of him said. During a certain calculation process,

There were calculation errors that led to deviations in the final answer.

"What do you do?" Liu Yuner asked seriously.

"I?"

"Working as an administrator in a certain library is a temporary job." Lin Fan said calmly: "The salary is not very high. After deducting social security, the salary is about 3,000 yuan. Moreover, I don't have a car or a house. I am currently renting outside.

A small apartment costs about a thousand and two dollars a month. In short...it's not suitable for the two of us."

Liu Yun'er frowned and asked seriously: "I'm not asking about this... I'm asking why you know about the scattering problem."

Lin Fan put down his knife and fork, picked up the tissue next to him, wiped the corners of his mouth gently, and said casually: "It's not a difficult question, how can there be so many reasons... I'm not bragging.

, you just used the scattering amplitude calculation formula, but there is actually another solution."

"Gaussian integral formula."

"Is this what you want to say?" Liu Yun'er said expressionlessly: "The calculation process is a bit complicated."

"..."

"complex?"

"It's not complicated." Lin Fan said with a smile: "Paper and pen!"

Liu Yun'er looked at Lin Fan, and then handed him her notepad and pen.

After taking the paper and pen,

Lin Fan started his calculation process, and at the same time set the calculator program on his mobile phone to scientific calculator mode, and just like that... he started his smooth calculation process, and this scene shocked Liu Yun'er.

Less than three minutes,

Lin Fan used the Gaussian integral formula to obtain the same differential scattering cross section as Liu Yun'er, but it took him even less time.

"Give!"

"I went to work."

After returning the paper and pen to Liu Yun'er, Lin Fan left in a hurry. By the time Liu Yun'er came to his senses, she had long disappeared.

he...

It’s actually librarianship?

Or temporary?

Liu Yun'er fell into confusion. Lin Fan easily solved the scattering problem, which caused Liu Yun'er's world view to collapse. When did a temporary worker in the library solve the problem in quantum mechanics without any effort?

Scattering problem.

However, Liu Yun'er was not in a hurry to find out Lin Fan. Anyway, she had his number and could always find him.

after,

Liu Yun'er was about to leave the restaurant. Just as she stood up and took a few steps away from the table, the waiter behind her suddenly stopped her.

"Miss!"

"You haven't paid yet."

Liu Yun'er was stunned for a moment. She thought Lin Fan would pay the money, but... she thought too much.

Arriving at the cashier,

Liu Yun'er opened the payment code on WeChat. She remembered that she only ordered one spaghetti bolognese, which cost about 78 yuan. However... it showed that 200 yuan had been deducted.

"I only ordered one dish of spaghetti bolognese, which is probably less than 80, why did you deduct 200 from me?" Liu Yun'er asked expressionlessly.

"That's the kind of lady."

"Your companion, the gentleman sitting across from you, did not pay."

Suddenly,

Liu Yun'er's face darkened. That guy named Lin Fan not only hit and run, but was also suspected of fraud!
