Of course Xu Mang knew what these people were doing. He just wanted to see the strength of these people. At a glance, it was clear that they were not very good at all. They were filled with dense rows of calculations. The result was

In the end it was empty.

It seems like I can't count anymore.

"You don't understand"

"This is a question of relativistic cosmology." Tong Min said with a smile: "Did you sprinkle a handful of cumin on it for me?"

"That's a must!"

"The soul of barbecue lies in cumin and ice-cold Fat Boy's Happy Water." Xu Mang said with a smile: "Wait a moment, I will help you get some bottles of Fat Boy's Happy Water. By the way, do you want sugary Happy Water or sugar-free Happy Water?

water?"

""

""

This guy is quite humorous and very popular with women.

“Coke Zero!”

"I want it too!"

The two returned girls smiled at Xu Mang and said.

but

This aroused Yang Xiaoman's vigilance. I'm sitting next to you. This big idiot is actually being attentive to others. What does it mean?

"Ahem!"

"The weather is so hot and my mouth is a little thirsty." Yang Xiaoman coughed lightly and said to Xu Mang intentionally or unintentionally: "I want to drink Coke Zero and I don't know who is willing to get it for me."

Xu Mang walked up to Xiaoman, glanced at Yang Xiaoman who had a look of expectation, and said angrily: "The cold box is placed next to you, and even though you bend over, you don't even want to pick it up. You

Tell me whether you are lazy or not?"

Yang Xiaoman:@#￥%!

I

Oops,

So angry!

However, Xu Mang's mouth was not forgiving, but his body was very honest. He chose a bottle of Coke that was not very cold among the many cold drinks, handed it to Yang Xiaoman's hand, and said seriously: "Drink less cold drinks.

It will accumulate into a disease in the future, and it will hurt you to death."

Yang Xiaoman felt angry and warm, rolled her eyes fiercely, and then opened the bottle cap with a joyful expression. Not to mention that the temperature was just right, this is the temperature of love.

"Coming, coming!"

"Here comes the iced Coke!" Xu Mang ran to the four international students with a smile and began to distribute things carefully.

"Thanks!"

"Thank you so much."

""

The four of them thanked each other, especially the two girls, who had a special affection for Xu Mang. Sometimes feelings are uncertain, just like Xu Mang and Yang Xiaoman, they got together because of the gravy in the buns.

, I have to hold him to sleep every night.

Although Xu Mang was wearing a hat and a pair of polarized glasses at this time, he could still feel vaguely handsome from the outline.

"well?"

"What's your name?" Liu Yan asked.

"I?"

"Call me Xiao Xu." Xu Mang said with a smile: "By the way, can you let me see your calculation process? I like the universe and am an astronomy enthusiast, so I chose the Department of Physics as a major.

It’s theoretical physics.”

"???"

"???"

"???"

Can't see it!

This guy is actually engaged in physics or theoretical physics!

etc,

Isn't this just right?

"Xiao Xu?"

"I didn't expect you studied theoretical physics, so you should know the theory of relativity very well?" Tong Min asked.

"It's okay."

"Let me take a look first?" Xu Mang was really curious about the content of their calculations. If these four people couldn't pass the calculations, they would not be able to solve the problem of oxygen fugacity in exoplanets. The problem of oxygen fugacity in exoplanets requires a lot of comparisons.

The calculation is very intensive.

"Give!"

That Liu Yan generously handed over all the manuscripts to Xu Mang, but Lu Bo was a little dissatisfied with this. It was too childish to give such important things to him as soon as he said they were his own knowledge.

.

But when he wanted to refuse, it was already too late. Xu Mang was reading their calculations.

at first,

They thought it was just a calculation problem, but it turned out that there was not only a problem with the calculation, but also a problem with the entire direction of thinking. Take the ability to calculate the expansion of the universe and the functional relationship between momentum and time. They used the wrong formula!

Xu Mang returned the manuscript to them in disappointment and said calmly: "You used the wrong formula."

"This problem requires the Robertson-Walker metric to describe space-time." Xu Mang said helplessly: "Get the non-zero components from the formula, and then use the geodesic equation to calculate, and finally get the thinking momentum and basic momentum, including

energy."

The words fell,

Several people present were surprised and looked at Xu Mang in disbelief.

"you"

"You analyzed it so quickly?" Tong Min asked in horror: "You just took a look at our calculation process?"

"yes!"

"Actually, this question is quite simple." Xu Mang said with a smile: "After all, I study theoretical physics. Relativity and quantum mechanics are my majors. It is not difficult to get the results."

"Give!"

Xu Mang handed this manuscript to the girl Liu Yan.

wrong!

This is not the case!

This theory of relativity is actually different from relativistic cosmology. If this guy was purely engaged in theoretical physics, he would not have been exposed to such profound issues, including the Robertson-Walker metric. How did he know this?

Looking at Xu Mang's leaving figure, the two international astrophysics students looked confused, and they felt like they had seen a monster.

"he"

"It's different!"

"It's not like an ordinary college student." Liu Yan said seriously: "Analyzing the cause of the problem in such a short time is definitely not something ordinary students can do. Have you ever seen such a person?"

Tong Min and Lu Bo shook their heads.

"never mind"

"Maybe it's luck." Tong Min smiled bitterly: "Then the second question the professor set for us is to assume that the early universe was composed of particle gases with no interaction and zero mass, and they were only affected by gravity."

at this time,

Xu Mang walked to Xiao Man with a disappointed look on his face and sat on the chair silently without saying a word.

"well?"

"What's wrong?" Yang Xiaoman asked with concern: "You were still in high spirits, why did you suddenly wilt?"

"well"

"Originally, I wanted to ask these four people to help me solve the problem of exooxygen fugacity, but the abilities of these people are not good enough." Xu Mang said helplessly: "The computing power is urgent, and the professional ability is also problematic. Of course, only

Limited to those two boys."

"The two girls don't count?" Yang Xiaoman rolled her eyes and said hurriedly: "I want to eat corn with a little seafood sauce on it."

"oh"
