I really don't want to lie down and win

at the same time,

Yang Xiaoman and Guo Tianmei hid in the shade of a tree and chatted, when they suddenly saw two barbecue tool men holding chairs and sitting next to the other two returnee girls. Li took out his tablet and began to analyze the problem.

what's the situation?

Not having a good grill and suddenly starting to work things out?

Is it...

Are all those who have stayed in school so boring?

Barbecue requires precise calculations?

"what's the situation?"

"What's the matter with these four guys?" Yang Xiaoman frowned, and asked Tianmei beside him, "What the hell are you doing together?"

"do not know."

"But one thing is for sure, these four people are not interested in barbecue." Guo Tianmei said: "In short, these four people are very high-end, especially those two boys. The concept was debated on the car for a long time, it seems... I don’t know what the problem is, it seems to be a calculation problem.”

"cut!"

"It's not that I deliberately belittled these four people, you Xu Mang brother is an authoritative expert in this field." Yang Xiaoman showed a disdainful expression, and said contemptuously: "Forget it... ignore these four people, anyway, it's not All the way."

on the other side,

Tong Min, Lu Bo, Liu Yanhe and Zhao Pengpeng are in a predicament. The four of them are not interested in barbecue. They take this opportunity to start to solve the problem of the expanding universe concept in relativistic cosmology, but...the four of them encounter hinder.

One problem is already tragic... If the energy and momentum are E0 and P0 respectively, assuming Rt0R0, thereafter the particles will travel freely except under the influence of the above metric, how can this calculate energy and momentum and time ratio?

How to describe the thinking kinetic energy of particles as kinetic energy?

From the R2drdR constant, how to calculate the particle energy?

The four were caught in an embarrassing dilemma in calculating the functional relationship of energy, momentum, and time in the expanding universe.

half an hour,

For half an hour, I had no clue.

At this time,

A voice came from behind.

"Your lamb skewers are ready!"

Holding a handful of mutton skewers, Xu Mang stood by the side with a smile on his face. He suddenly raised his head to look at the calculation process in the hands of the four, and asked curiously, "What are you doing?"

......

Chapter 569 The Last Hope (3/3, add more for Bit Dark)

Of course Xu Mang knew what these people were doing, he just wanted to see the strength of these people, let alone...it's really not that good, it was filled with a row of calculations , but ended up empty.

It seems... can't count.

"you do not understand..."

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

"That's a must!"

"The soul of barbecue lies in cumin and iced fat boy's happy water." Xu Mang said with a smile: "wait a moment... help you get a few bottles of fat boy's happy water. By the way, do the two ladies need sugar happy water? Sugar-free happy water?"

"..."

"..."

This guy... has a good sense of humor and is very attractive to women.

"zero COLA!"

"I also want!"

The two returnee girls smiled at Xu Mang and said.

but...

This aroused Yang Xiaoman's vigilance, I am sitting beside my old lady, this big idiot is courting others, what do you mean?

"Cough cough!"

"It's so hot... My mouth is a little thirsty." Yang Xiaoman coughed lightly, and said to Xu Mang intentionally or unintentionally, "I want to drink Coke Zero... I don't know if anyone is willing to get it for me."

Xu Mang walked up to Xiaoman, glanced at Yang Xiaoman who had a look of anticipation, and said angrily, "The cold box is placed next to you, and you don't even want to take it even if you bend over. You Tell me about yourself... lazy or not?"

Yang Xiaoman: ...!

I...

whoops

Mad!

However, Xu Mang's mouth is unforgiving, but his body is very honest. He picked a bottle of Coke that wasn't too cold among many cold drinks, handed it to Yang Xiaoman's hand, and said seriously: "Drink less cold ones. It will accumulate into a disease in the future, and the pain will not kill you when the time comes."

Yang Xiaoman was angry and warm, she rolled her eyes viciously, and then opened the bottle cap with a happy face, not to mention...the temperature is just right, this is the temperature of love.

"I'm coming!"

"Iced Coke is here!" Xu Mang ran to the four foreign students with a smile, and began to distribute things seriously.

"Thank you!"

"Thank you so much."

"..."

The four of them thanked each other, especially those two girls, who had a good impression of Xu Mang. Sometimes feelings...maybe, just like Xu Mang and Yang Xiaoman, because of the gravy in the buns, the two of them left We are together, and we have to hug each other to sleep every night.

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

"Ugh?"

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

"I?"
