"Professor Xu..."

"I... I want to quit. A girl stood in front of Xu Mang, lowered her head, and looked at Xu Mang embarrassedly: "It's completely different from me at school, there is not even a person to talk to here." ”

Xu Mang looked at this girl, the eleventh person who has withdrawn so far, and the last one he predicted, two weeks... There are eleven people left, although the conditions are quite hard, but they haven't worked hard like this, right?

"Is it really so hard?" Xu Mang couldn't help but ask: "Except for being bored... You alright. ”

"It's not..."

"There were still people talking to me, but it turned out to... Everybody's gone. The girl said helplessly: "Now... The rest is to do research every day, and to discuss it during meals... Stand. ”

Xu Mang: Embarrassed

Nima,

Isn't that great?

Who introduced this?

"Oh..."

"Then you go, there is no contract anyway. Xu Mang said.

Looking at the back of the girl leaving, Xu Mang began to reflect, is the location really offset? I couldn't help but take out my mobile phone and click on the map software, and directly navigate to the city center, which shows that it is only more than 20 kilometers.

It's okay...

That is, more than 20 kilometers, according to the speed of riding a motorcycle in the middle of the night, it will take ten minutes.

Thinking back to the present,

There are only six people left in the huge laboratory, and these six people put a quotation mark, because they often have to go to class, which means that there are only five people left working in such a large laboratory. Okay, too.

Wrong

There is also a chef who cooks.

"Ugh..."

"It's really miserable!" Xu Mang sighed, thinking about the gravitational wave joint detection laboratory, I heard that there are more than 30 people, and then compare myself with them, it is the difference between heaven and earth.

Licked the wound for a while,

Xu Mang silently came to the place of work, Wang Ai and Dong Yu were calculating data in front of the computer, as an idler, he walked over quietly, standing on the side and watching the two calculate, not to mention... It's more accurate, but there's just something wrong.

"Professor Xu?"

"Did you leave another one today?" Dong Yu asked curiously: "A few days ago, I saw that something was wrong with her, and I thought she was sick at first, but I only found out later that I was thinking about how to leave this place." ”

“...”

Xu Mang didn't speak and left silently.

“？？？”

“？？？”

Wang Ai and Dong Yu glanced at each other, and each saw the confusion in each other's eyes.

"Xiao Ai?"

"It's... What the hell is going on?" Dong Yu said with a puzzled face: "It seems that Professor Xu is in a very low mood today, it seems... It seems to be a breakup, and under normal circumstances, people who break up are like this. ”

"Impossible!" Wang Ai said solemnly: "I suspect that there have been too many people recently, and I can't accept such a situation at once, which leads to a heavy mood." ”

"I think it's pretty good, and I don't know why those people left. Dong Yu said helplessly: "Many people envy me, after all, I can do research in Professor Xu's project, and I can quickly improve my ability." ”

meanwhile

Xu Mang came to Hu Jie and Zhang Yapeng, the two are responsible for finding neutron stars and black holes, but at present, it seems that the work of the two is very tiring, all the data are copied by Brother Chuan Xiao before, and the two of them want to find celestial objects that may detect gravitational waves in the vast data.

"Professor Xu?"

"Ignore me... Go ahead. Xu Mang left.

“...”

“...”

The two also feel that Professor Xu is a little different today, obviously today is what they look like after the breakup, depressed... There was an expression on his face that saw through the red dust.

"Hu Jie..."

"What's the situation?" Zhang Yapeng frowned and asked, "Is Professor Xu out of love?"

"Impossible!"

"Professor Xu's girlfriend... I saw it, I met it once at school, when Professor Xu and his girlfriend were intimate. Hu Jie said seriously: "I think there are too many people in the laboratory, and I can't accept this situation for a while." ”

Hu Jie's words were agreed by Zhang Yapeng, and it seems that this is indeed the case.

Eleven people walked away at once, and no one could stand it.

At this point,

Xu Mang returned to his office, in fact, the work of detecting gravitational waves is very simple, that is, to find the corresponding neutron stars and black holes, and then detect them, this is only a matter of time, and there is no need to prove it, the predecessors have all completed it.

But...

Just after looking at Wang Ai and Dong Yu's calculations, Xu Mang suddenly realized a problem... Detection accuracy may not be enough!

This is not out of nowhere, Wang Ai is calculating the time of a caliper distance, this value is too large, even if gravitational waves are detected, there is no difference in the calculated value.

Xu Mang began to improve the calculation method, but no matter how hard he tried, this value still could not be reduced, at this time Xu Mang set his eyes on the laser interferometer, is this instrument not good.

But this idea was soon dispelled, and the measurement method created by laser interferometer is the highest level of accuracy in the history of human beings for tens of millions of years, and there is nothing more accurate than this, so there is only one case... There is another computational process in this world that can be accurate to the known limits.

"The system... I need a mathematical tool to accurately calculate gravitational waves. ”

[Exchange value of mathematical tools that accurately calculate gravitational waves through system recognition: 1,000,000 (mathematical skills)]

[Exchange value of mathematical tools that accurately calculate gravitational waves through system recognition: 2000000 (physics skills)]

[Exchange value of mathematical tools that accurately calculate gravitational waves identified by the system: 1,000,000 (astronomical skills)]

[Requirements: Intelligence Level 4]

[Requirements: Proficient in all three skills]

it...

Nima!

Is it so harsh?

Seeing the exchange requirements given by the system, Xu Mang knew that with his current ability, he would not want to find gravitational waves in this life, without a matching calculation tool, everything was funny, and success only existed in the fantasy of the brain.

Quickly rising to the fourth level of intelligence is a huge challenge for Xu Mang at present, but with such a lack of tasks, it seems that it cannot be achieved in a short time.

Dissolved and unable to disband...

It's not okay to waste other people's time.

Other items can only be sought temporarily.

"Brother Chuanxiao..."

"There's one thing I need to discuss with you. ”

...

"What?"

"Lack of calculation tools?" After Brother Chuan Xiao heard Xu Mang's words, he looked at him with a surprised face: "You... Are you sure?"

"Yes!"

"Just now I looked at the calculation process of Wang Ai and Dong Yu, and found that the change in the duration of the edge through the light is too large. Xu Mang said seriously: "It's so big that it can't be spoken, according to the current situation, we will never find gravitational waves." ”

Brother Chuan Xiao frowned, this matter can't be blamed on Xu Mang, everyone is doing this for the first time, and being able to find the mistake at the stage just started is much better than the mistake that is not clear after the end.

But...

This is in trouble!

How do you tell the members about this?

"I think... You can't hide it. Brother Chuan Xiao said seriously: "And they are a member of this laboratory, and they have the right to know these inside stories, and everyone will look for this calculation tool together." ”

Xu Mang thought for a moment and said seriously: "For the time being, study the others, and put the gravitational waves on the side first." ”

"That's all there is to it. ”

"But you still have to make it clear to the members, otherwise," said Brother Chuan Xiao.

"I will!"

soon

Xu Mang summoned everyone and held a short meeting in the conference room, the main content of which was to describe the big trouble they were currently encountering, about the lack of computing tools, but everyone was not discouraged by this, and it is common to encounter such problems in a Nobel Prize-level research project.

After the vote, Brother Chuan Xiao led the four to study the problem of neutron stars and black holes, and collected relevant data by the way, while Xu Mang tried his best to find calculation tools.

Luck in misfortune,

No outsiders know about this matter, which also saves Xu Mang a lot of trouble.

Back to the apartment,

Xu Mang didn't see Xiao Man's figure, she has been getting busier and busier recently, and seems to have become an investment fund, and then recruited a group of students who are good at mathematics to invest with her, which leads to fewer and fewer opportunities for the two to meet.

After making himself a bowl of egg fried rice, he sat at the table alone, flipping through his phone while eating, looking at whether there were any major discoveries recently.

Look at it,

Xu Mang noticed a news item titled Probability Problems in the Quantum World.

It seems to be from Qing University.

The central idea of this news is the wave function, and the research team believes that the wave function in a quantum system can only describe the probability of a group.

Not to mention,

Xu Mang agrees with this view, the probability of a quantum system behaving in one way and another, in the world of quantum mechanics, probability is everything, and in a simple system, it is possible to start from the calculation of the wave function and get all the other information about it.

However...

In the face of extremely complex systems, the wave function can only describe a set of probabilities.

This is what the Tsinghua research team wants to say, a wave function in a complex quantum system can only describe the probability of a group.

[Trigger Mission: World of Quantum Probability]

[Explanation: Revealing the full picture of wave function effects in complex systems]

【Reward: Upgrade Card*10】

I...

This... How can it be so special!

Xu Mang's head suddenly became bigger, although he was very short of upgrade cards, but the difficulty of this task was too high, and Qing Da's research was not wrong, and in the face of complex systems, it was impossible to get the full picture of the wave function effect.

So this task is an impossible task!

"You have a new lawyer's letter, please check it!"

Then

The mobile phone rang a new ringtone, since using the ringtone of "Poultry You Are Too Beautiful", Xu Mang really received a lawyer's letter, but after consulting the legal department of the old father-in-law group, he told him not to panic, the other party has no IQ.

But just in case, Xu Mang still changed the ringtone.

"Hello?"

"My dear...," Yang Xiaoman's voice came out of his phone, "Help me save a little dinner, and I'll be back in half an hour." ”

"Oh. ”

After receiving the call, Xu Mang hurriedly cut the shredded vegetables, diced ham, and beaten eggs, and after preparing all this, he came to the computer desk and began to think about the full picture of the wave function effect in the so-called complex system.

But

The more Xu Mang thought about it, the more incredible he felt, could this really be done?

Obtain the basic details describing an isolated quantum system by direct observation... How is this possible? Unless there is a way to find information about the possibility of atoms at a specific location in the system in space.

So what is the difference between this level of accuracy and laser interferometry?

Alas?

Laser?

Xu Mang suddenly thought of something, and then a bold and expensive idea gradually formed in his brain.
