When a blond woman saw Xu Mang, she seemed to have gone crazy. Her eyes were full of admiration. She hurriedly sat next to her and kept asking questions. Xu Mang was embarrassed. For a moment, she didn't know.

what to do.

"Ellie!"

"Be more reserved, you will scare Professor Xu." A dark-skinned woman next to her hurriedly said to the emotional Ellie.

The words fell,

The dark-skinned woman said sheepishly: "I'm sorry, Professor Xu. Ellie's major is condensed matter physics. Her idol is you. When she meets her idol for the first time, she will inevitably be excited and make you laugh."

Well?

She is Ding Jun’s girlfriend?

It seems to be different from the one in my impression. It looks too ordinary, right?

Although Xu Mang can't recognize the appearance of European and American people, he can still distinguish between good-looking and ugly. The girl named Ellie doesn't look like her. Except for her blond hair, her other conditions are not that good.

What's going on?

Why do all my friends like to find ordinary girls?

Could it be that I am vulgar?

"Professor Xu?"

"Why did you come here suddenly? I heard Kai say before that he and you are friends, and the relationship is very good. I dreamed of meeting you one day, and this dream actually came true." Ellie said and rushed.

Ding Jun said: "My dear, let's change a restaurant and go to Michelin three stars."

""

"Xu Mang will be here soon, there's no need to go to Michelin Star, right?" Ding Jun said helplessly.

"No!"

"It's because Professor Xu is here that we have to go to eat with three Michelin stars." Ai Li is a very stubborn and willful girl. At this time, her little temper came up and she said seriously: "It's rare for Professor Xu to come here, we must

Be well entertained."

"No no no!"

"No, thank you." Xu Mang saw that Ding Jun's face turned dark, indicating that the young couple might quarrel, so he hurriedly smiled and said: "This place is very good. I asked Ding Jun to book here."

"ah?"

"Oh, then let's go here." Ellie said.

moment,

Everyone started to order. Xu Mang stayed the same and ordered a steak set and a pasta set. The prices were not cheap. These two sets cost almost one hundred and ninety-nine dollars, which is less than one thousand fourteen.

"Fuck!"

"Why is Ding Jun's place so expensive?" Xu Mang said in Chinese: "Two hundred dollars, it's one thousand fourteen!"

""

"I said you calculate money like this?" Ding Jun said helplessly: "Directly based on the exchange rate? Isn't this a hooliganism?"

Xu Mang:???

What's the meaning?

Don’t we need to follow the exchange rate?

"Is it possible that the exchange rate between our country's money and the US dollar is already one to one?" Xu Mang asked cautiously: "Am I actually a fake Chinese?"

"you"

"this"

"Forget it, forget it. Anyway, you have a wife who is very good at making money." Ding Jun gave up the debate with Xu Mang on purchasing power. He could also see that Xu Mang was an idiot in this regard. Instead of arguing with an idiot,

, it is better to fight with someone who understands.

At this time,

Ellie said in the same words: "Professor Xu Xu, don't argue with Kai, he is an idiot."

Xu Mang looked at Ellie in surprise. He never expected that Ellie could speak. Although she spoke intermittently, the basic meaning was expressed very clearly. It seems that she should be more careful when speaking in the future. It seems that the whole world is talking about words.

"Did you learn your good speaking skills from this idiot?" Xu Mang asked with a smile.

"Um!"

"After all, I am his wife." Ellie said with a smile, "It's normal to know my husband's language."

Um!

good!

I’m sure about this marriage!

Xu Mang was satisfied with Aili's performance and agreed to marry the two on the spot. He then said to Ding Jun: "Ding Jun, it seems that you two are in true love. After all, you only look like this. You are not even 100% better than me."

You are so handsome, it is simply unreasonable that you can find such a good girl!"

Ding Jun is so angry, why is this guy still so mean?

At this time,

The waiter delivered the lunch that everyone ordered, and then they ate happily. At first Xu Mang thought that what he ordered was just an ordinary steak, but a large piece of it was served. Later he realized that it was a tomahawk steak, which was very big.

Not to mention,

This steak tastes strong enough. Only when you eat this steak can you feel like you are eating steak. When you eat other steaks, you will feel like you are just eating beef.

"Ellie."

"Has your team encountered a certain problem recently?" Ding Jun said seriously: "Why don't you ask Xu Mang and let him solve this problem."

The words fell,

The five people present instantly became energetic. All five of them, including Ellie, were in the same research group. Recently, there was indeed a problem that trapped several people. Even the instructor was helpless. They were already on the verge of despair.

Now, Professor Xu is here and all the problems can be solved.

"Um!"

"Professor Xu, can you help us?" Ellie asked cautiously: "This is a calculation problem that no one in our school can solve, including the professional mathematics professors and students. They are powerless when encountering this problem.

."

Xu Mang thought about it. It was Brown University, but it wasn't at this level. This school seemed to only be ranked among the top ten in the United States for physics.

"oh"

"No problem!" Xu Mang nodded.

soon,

Lunch is done,

Xu Mang was taken directly to Brown University by Ding Jun and his group, all the way to the famous Burroughs-Howley Laboratory Building. This is a comprehensive building for engineering and physics. In fact, the level of Brown University is quite high.

of.

In particular, undergraduate and doctoral students have extremely high admission thresholds, making it one of the most difficult universities in the United States to admit.

Although the number of people in today's universities continues to grow, Brown University still maintains a small but elite elite education. According to Ding Jun, there are only 6,000 undergraduates, 2,000 graduate students, and only 700 full-time teachers.

result,

On this scale, seven Nobel Prize winners have been produced.

"Professor Xu, this is the problem." Ellie pointed to a set of complex calculation processes on the computer screen, and said helplessly: "We have been stuck for three weeks and have contacted many, many people, but they all said they couldn't solve it."

Xu Mang couldn't help but froze when he saw this long section of responsible formula. This seemed to be not a simple condensed matter, but a topological insulator with a topological concept. It is one of the most important quantum materials in condensed matter physics research.

one.

hehe,

Not simple!

Ding Jun has also learned the routine. This is not something that can be done easily. He obviously has to raise his hand twice.

Faced with the sudden silence of Xu Mang, everyone present was very nervous, fearing that Xu Mang would answer no question. If he couldn't even answer, this research project would basically be declared a failure.

"this question"

"It's not difficult. Do you have paper and pen?" Xu Mang said with a smile.

The words fell,

Everyone was stunned for a moment, has this been solved? Just glanced at it?

Most people were confused by Xu Mang's magical operation. He just glanced at the calculation formula. He didn't even ask anything about this experiment. It was completely inconsistent with scientific common sense to solve it directly.

After a while,

Xu Mang got paper and pen, sat in front of the computer alone, and started to calculate this problem. Not to mention that this problem was really difficult. The difficulty was not the thinking, but the calculation steps, which were extremely complicated.
