Chapter 317

"Are there any more blackboards left?" Xu mang looked at Du yuan and asked calmly, "I need three blackboards."

"Blackboard?"

"Xu Dashen... What do you want the blackboard for?" Du yuan asked with a confused face: "if you want to calculate, isn't it another pile of A4 paper?"

"I need to derive formulas for easy viewing."

"Oh..." Du yuan nodded. He was in charge of calculation from the Department of mathematics. He quickly understood what Xu mang wanted to do, and said in a hurry: "I'll help you to move three blackboards."

As a result,

Du yuan called together three male students to help Xu mang move the blackboard.

The rest of the people, looking at a face indifferent Xu Mang, some confused do not know what he wants to do, since it is determined impossible, what blackboard? What more derivation formula?

"Xu Da Shen?"

"You... Didn't you say it was impossible?" Chen Mu curiously asked, "what are you?"

"Well..."

"I just looked at it and thought there was still a chance to rescue." Xu mang said with a smile: "life always needs hope. If there is no hope, what is the meaning of living?"

"..."

"..."

"..."

"..."

although we understand the truth,

but it's very difficult to listen to it.

does every academic bully have a philosophical heart?

Many people at the scene were not used to Xu Mang's theory. They heard this truth countless times, but every time it ended in tragedy. Sometimes, the chicken soup for the soul is a very disgusting product.

Soon,

Xu mangyao's three blackboards arrived, and they were placed on the edge of the original blackboard.

Immediately Xu mang began his own calculation.

However, five minutes later, Xu mang was still in a state of confusion. No matter from which angle to explore and think, the research results of the group led by Professor Guan could not find any problems in their physical properties, but once the calculation occurred, it was fundamentally wrong.

It's strange...

How could this be the case?

The time caliper is also correct. According to the calculation of this model, the time scale is set to be greater than e ^ 60. This time just makes the universe flat, uniform and isotropic. Is the time right... Is it any other problem?

Finally,

Xu mang fixed the problem on the problem of flatness. Although there was enough time for his universe to be flat, this model did not provide evidence of how flat it was.

But he gave up the wrong idea for a long time... This is a worldwide problem, and it is normal that there is no evidence. If Professor Guan leads a student group to solve this problem, he will perform on the spot and explode in situ.

Don't understand,

this is the rhythm of death.

"What about the system? Can you give me a breakthrough? I'll take care of the rest. "

[the exchange value of the key points of this problem: 10000 (physical skills)]

[the exchange value of the key points of this problem: 10000 (astronomical skills)]

not expensive,

direct payment!

After a moment,

Xu mang suddenly realized that the original problem lies in the quantum fluctuation problem. In the model of Professor Guan's group, the particle density of each region of the universe is consistent, and the temperature of each region is also the same.

I see!

Then we have to push the model down and start the calculation again.

"Chen Mu!"

"Come here for a second!" Xu Mangchong Chen Mu shouts.

Soon Chen Mu to Xu mang side, curiously asked: "Xu Dashen... What's the matter?"

"Give me the basic parameters of your model." Xu said.

"Ah?"

"Do you remember Xu Da Shen?" "A lot of them," Chen said

"Please remove the word" Ma. " Xu mang said with a smile: "I have the strongest memory in the country, none of them."

"..."

"Oh."

Then, Chen Mu began to describe the basic parameters of the model to Xu mang.

Coincidentally,

the mobile phone rings, and it's Xiaoman. At this point, it's called. I guess it's checking the post, right?

"Hello?"

"What are you doing?" Xu mang asked curiously, "I'm busy."

"Where is it?" Yang Xiaoman asked gently, "are you sitting in Starbucks?"

"Well..."

"yes!" "Where else can I go?" said Xu mang with a smile

At this time,

Chen mu, who was lacking in strength, could not help but remind him: "Xu Dashen... Do I still want to read it?"

“...”"..."

Yang Xiaoman: (* ￣＾)

Xu Mang: (~ △;)

their conversation was interrupted for ten seconds.

"Good!"

"You're starting to cheat me!" Yang Xiaoman gnashed his teeth and said, "where are you now? Who is the girl on the edge? "

"Xiaoman, listen to my explanation... In fact, this..."

Xu Mang's half explanation was interrupted by Chen Mu again.

"Xu Da Shen?"

"Shall we begin?" Chen Mu asked.

"Ha ha!"

"Don't you think I'm not gentle enough?" Yang Xiaoman sneered: "if you have the ability, don't hold me tonight."

"Ouch..."

"it's not what you think... In fact...

" get out! "

PA,

was hung up by Xiaoman.

Xu mang looks at the interrupt interface, his back is a little chilly, it seems that tonight is a sleepless night... This woman is expected to be crazy.

"Let's go..."

"speak a little faster." Xu mang put away his mobile phone and said to Chen mu.

"Oh..."

ten minutes later,

Xu mang basically mastered all the information, and then began to re dredge the model.

Chen Mu stood on the edge, looking at Xu mang with a confused face. He didn't know what he was going to do. He just understood that he was calculating. As the most gifted student in the whole group, he found out Xu Mang's behavior two minutes later.

This is...

this is the whole process, and it is calculated again? But is it time?

It took three weeks to get these contents out. Now it takes Xu Mang and Xu Dashen alone, and then spend a day... It seems impossible?

"Xu Da Shen?"

"Are you coming tomorrow?" Chen Mu asked.

"Eh?"

"Don't know..." Xu mang said casually, at this time he was full of brain how to solve the density and temperature problem in front of him.

After thinking about it,

Xu mang definitely cut down the complexity and deduced a similar concept. Maybe we can use hairless law to explain this problem.

In fact, the universe horizon is similar to the black hole horizon. The only difference is what exists at the other end of the horizon. Of course, this belongs to philosophy, not to the scope of physics.

According to the hairless law, Xu mang can get the concept of proportional expansion in the stage of inflation. The energy density will decrease with the increase of volume. The density and volume of cold matter will be inversely proportional, the energy density and the cubic power of volume will be inversely proportional, and the radiant energy will be inversely proportional to the fourth power of the volume.

Uniformity, anisotropy, curvature will be reduced, the number density of strange particles and photons will be reduced... And finally close to the vacuum, symmetric universe.

Er...

basically.

According to these ideas, Xu mang began to modify some basic parameters in the inflation model set by Professor Guan, which is a pure mathematical calculation.

Chen mu, who was cold treated, just stayed by Xu mang for three minutes and then left in silence. Xu Mang and Xu Dafen in his work were so terrible that he exuded a kind of repressive temperament... No, it was a kind of autistic atmosphere.

Standing beside him, I feel like an idiot.

At noon,

Xu was still addicted to calculation.

"Xu Da Shen?"

"It's noon... It's time to eat." Du Yuan said cautiously.

"No!"

"No time!" Xu mang dropped a sentence and wrote the formula on the blackboard. The probability density of space particles is p (x) = | ψ a (x) ^ 2, and the mean value is x = x | ψ a (x) | ^ 2 (DX)...

Du yuan was stunned for a moment, looking at the things on Xu Mang's blackboard, his face was full of confused words.

What is this?

I don't know how to read it?

"Xu Dashen..."

"what is this?" Du yuan asked in a low voice.

"A formula derived from the uncertainty principle to calculate the energy change at any position in space." "This kind of change violates the law of conservation of energy, but it happens anywhere in space, and the change time is very short. The law of conservation of energy still holds when we observe it on the cosmic caliper," Xu said

"Sorry..."

"excuse me."

Du Yuan said sorry to Xu mang with a face of apology, and then walked away from the laboratory, leaving Xu mang alone in the laboratory.

At the same time,

Du Yuan said to his companions, "lying trough... Do you know what I just experienced?"

"I'm so... Almost autistic. I'm so cheap. I shouldn't ask Xu Da Shen questions." Du yuan sighed and said helplessly, "if I graduate... I'd better go to work.""Is it so terrible?"

"God Xu is also a man, not an animal." A student said with a smile, "what is Xu Dashen doing when he writes and draws on the blackboard one morning?"

Chen Mu said: "Xu Dashen pushed all our calculations down, and then modified some values based on the original ones... But I'm a little puzzled. Can Xu Da Shen bypass the step of building models?"

"God knows."

"Anyway, I'm dead hearted... Even if Xu comes, he can't save me." A student said with a bitter smile.

...

laboratory,

Xu mang sat in front of the blackboard and looked at his calculation process, and opened the sage mode, another special name is called daze.

It seems that

is wrong again.

Xu mang is already confused. After solving the symmetry problem, he finds that there is a new problem.

However, this problem does not involve mathematics, but needs to be derived with the help of models. That is to say, it is correct to calculate the problem from the mathematical point of view, but it is a mess from the physical point of view.

What an embarrassment...

I can only do it again.

Finally, Xu sat down in front of the computer and began to build a brand-new model based on the research of Professor Guan's group. In fact, they were almost the same, but Xu mang dealt with some details, although he didn't know whether it was right or not.

"System... Open animal mode!"

After all, time is money.

...

the lunch break was very short for the students, just in the blink of an eye. Members of the research team went to the laboratory one after another.

Chen Mu was the first to arrive.

"Ah?"

"Where's Xu Da Shen?" Chen Mu looked around, but did not find Xu Mang's figure. After that, he saw the three blackboards. He took a few steps to get close to him, as if he had been rewritten, because there were obvious traces of the board rubbing.

Chen Mu tried to understand the calculation process on the blackboard, as well as some messy formulas. Soon she failed, and about two-thirds of the content could not be understood.

Fortunately,

Du yuan and his group came to the laboratory.

"Come here and have a look. What did Xu Da Shen write?" Chen Mu called out: "full of three blackboards."

"..."

"I said Chen Mu didn't bring such humiliation." Du Yuan said angrily, "if we can understand Xu Da Shen's formula, will we still stand here and chat with you?"

"Since I can't understand it, I'll analyze it together." Chen Mu said, "hurry up!"

For a moment,

a group of people gathered around the three blackboards, staring at the formulas and formulas on them.

And then... Everyone was autistic.
