With lasers!

Using the precise principle of a laser interferometer, thousands of laser devices are hung in an enclosed space to determine the probability that an atom in space may be at any given location.

But... This is the ideal situation that stays in his mind, Xu Mang feels that this seems unlikely, thousands of laser devices are a little expensive.

should be a single laser, in a small enclosed space,

Click,

The door of the apartment was opened, Yang Xiaoman walked in in a hurry, Xu Mang glanced back, and found that she had lost a little weight recently, and her expression was a little tired.

"Coming back?"

"Hmm..."Yang Xiaoman pouted: "Hurry up and make dinner, I'm starving to death..."

"Yes!"

Xu Mang hurriedly ran to the kitchen and made a bowl of egg fried rice for Xiao Man, and after a while, he saw Xiao Man gobbling it up, not caring about his ladylike image at all, being able to make a girl who loves beauty so hungry like this, it seems that she is so busy that she doesn't even have time to eat lunch.

"Xiao Man?"

"Huh?"

"How much money did you make?" asked Xu Mang.

"Not much..."

"That's more than two million in total. While eating egg fried rice, Yang Xiaoman posted a message in the WeChat group and said indifferently: "The impact of the side effects of international trade tensions on the euro may exceed the dollar, and the market demand for the dollar will exceed the euro, resulting in a decline in the euro against the dollar." We took advantage of this..."

Xu Mang: ???

What is she talking about?

"Ahem!"

"Looking at your cute expression, I knew you might be confused. Yang Xiaoman raised his head, looked at Xu Mang's confused expression, and said with a smile: "We found that the eurozone is more open to trade than the United States, which means that the ratio of total trade to GDP is higher than that of the United States." ”

"Okay, don't say it!" Xu Mang hurriedly stopped Yang Xiaoman from continuing to pretend to be forced, he really couldn't understand what she was talking about, what was high or low...

"Hee-hee!"

Seeing Xu Mang's confused state, Yang Xiaoman was still happy, it had been a long, long time since Xu Mang had such an expression, since falling in love... This guy has become a representative of omniscience, and now he is finally known to himself to the weakness, this guy does not understand the economy!

"Don't!" Yang Xiaoman hurriedly said: "What's wrong with listening to me? I used to be your listener, but now you will die if you are a listener?"

“...”

"Tell me. Xu Mang said with a smile.

"We have established a valuation model, and from this model, we can see..."Yang Xiaoman kept talking to Xu Mang, the more he talked, the more excited he became, and the more excited he was, the more he liked to talk.

however

Xu Mang listened to these people's contents, as if listening to a book from heaven, slowly... Sleepiness swept over his body, and he finally fell asleep while sitting.

Yang Xiaoman: (# ̄~ ̄#)

It's so angry!

This guy is too disrespectful, right?

In fact, Yang Xiaoman misunderstood Xu Mang, not that Xu Mang wanted to sleep, but a natural reaction that belonged to him, when he encountered something he didn't understand, especially related to knowledge, the brain would secrete a kind of melatonin, and it was because of this reaction that sleepiness struck.

As soon as the words fell,

Xu Mang's melatonin secretion stopped, and then he woke up, opened his eyes and saw Yang Xiaoman, staring at him viciously.

“...”

“...”

"Excessive!" Yang Xiaoman pouted, her face full of the three big words 'Coax Me', she needed to eat a wave of dog food to heal the scars in her heart.

Without further ado,

Xu Mang hurriedly came behind the airport, hugged her from behind, and said gently: "Don't be angry... I'll work a little harder in the evening. ”

Words

It's better to take action,

Xu Mang thinks so.

Following

Xu Mang, who had back pain, went to the building of the physics department, and he wanted to find the big man in optics, Professor Li Aimin, and ask the school if there was any laser equipment that matched his experiments.

Passing by the fruit shop,

Xu Mang suddenly stopped...

...

Bang bang!

"Please come in!" Professor Li Aimin was in the office when he heard someone knocking on the door and answered casually.

Followed by

Xu Mang carried Xue Dingxu's fruit basket, came to Li Aimin's office, and said with a smile: "Professor Li?

“...”

Looking at Xu Mang's embarrassed expression, Li Aimin looked helpless, he... He finally came to harm the optics profession, although he knew that this day would come sooner or later, but when this day came, his heart was extremely melancholy.

"Professor Xu..."Li Aimin rarely interacts with Xu Mang, and they are very unfamiliar with each other, so unfamiliar that they can't call each other's names.

"Don't, don't!"

"It's too rusty. Xu Mang hurriedly smiled and said, "Professor Li, you can call me Xu Mang, so that we can get closer to each other..."

Li Aimin smiled bitterly: "Xu Mang... What are you doing in my office all of a sudden?"

"What..."

"Is there any laser equipment in the optics laboratory?" asked Xu Mang.

"Of course, the optics major has laser equipment. Li Aimin nodded and asked curiously, "What kind of laser equipment do you need?"

Xu Mang didn't know how to describe it for a while, and after thinking for a while, he hurriedly said: "I need a special laser device that can detect an atom in the air, and it can detect a single atom. ”

Li Aimin was stunned for a moment, he had already misheard, and hurriedly asked, "You... What did you just say?"

"I need a laser that directly detects atoms in the air. Xu Mang said seriously.

“...”

Li Aimin fell into silence, looking at Xu Mang in a daze, and the office was silent for a while.

"Xu Mang. ”

"What did you ask me before?" asked Li Aimin.

"A laser device that detects atoms in the air. Xu Mang repeated the request for the third time.

"No!"

"The previous sentence. ”

"Is there any laser equipment in the laboratory of optics?" Xu Mang repeated the first sentence.

Li Aimin said solemnly: "No!"

Xu Mang: Embarrassed

it!

Is it necessary?

We're all colleagues... What are you doing with such a slamming door.

"Xu Mang..."

"A laser device that can detect atoms in the air, do you know what the concept is?" Li Aimin almost went crazy, and said angrily: "How can there be such a device... Not in the whole world. ”

“...”

Xu Mang smiled awkwardly.

"What exactly are you going to do?" asked Li Aimin.

"It is intended that in an enclosed space, a laser device that can detect atoms is suspended, and then the probability of the possible location of an atom in the enclosed space is determined. Xu Mang said seriously: "Verify a probability problem of quantum mechanics. ”

"I'm sorry. ”

"We don't really have such equipment. Li Aimin said helplessly: "Don't say I don't... You can't find anything like it all over the world. ”

“...”

"If I design a laser device that can complete my experiments, can you help me build it?" asked Xu Mang.

"Xu Mang!"

"There's no denying you're pretty good, but designing a laser machine isn't as simple as you think. Li Aimin said solemnly: "This is completely opposite to your approach to theoretical physics. ”

Xu Mang thought about it for a while, what Professor Li said was not wrong, it was indeed the opposite of his major, but... Who knows for sure?

"Xu Mang..."

"If you change the experimental method, you really can't do this. Li Aimin persuaded: "It's not me who strikes you to design a laser device, you don't have this ability, after all, the fields are different, and you belong to the theoretical type." ”

"Oh..."

Xu Mang's 'oh' was a bit stubborn.

"I'm leaving. ”

Words fall,

Carrying Schröding's fruit basket and leaving the office.

Professor Li looked at his back and knew that Xu Mang would definitely be unconvinced, but what could he do?

"Xu Mang!"

"Huh?"

"Our optics major may be able to help you with that. Li Aimin hurriedly called out to Xu Mang.

"No need. ”

"I'll do it myself. Xu Mang smiled and said, "I'll go first." ”

...

Back to the apartment,

Xu Mang sat on the sofa and rethought this experiment, how to solve this problem, is there a problem in the experiment itself?

"Huh?"

"Didn't you go to the lab today?" Yang Xiaoman walked out of the room with Hache, only to see Xu Mang sitting alone on the sofa, his brows furrowed, which was heart-wrenching, and hurriedly said, "What's wrong?"

"Uh..."

"Nothing. Xu Mang smiled: "You want to go out?"

"Hmm!"

"We are making short-term investments with returns of more than 30 percent, and today we are going to discuss the next plan. Yang Xiaoman said: "Am I good at your future wife?"

"Awesome!"

"The thief is awesome!" Xu Mang smiled.

Yang Xiaoman glanced at him, raised his arrogant little head, and then walked into the toilet, after a simple wash, he still saw Xu Mang's bitter gourd face, and immediately walked up to him, held Xu Mang's cheek, and said seriously: "Give the old lady a happy one!"

Words fall,

Xu Mang made a classic appearance of smiling and not smiling.

Yang Xiaoman glared, but finally closed his mouth.

(*￣3) (ε ̄*) Chirp!

"I'm leaving. ”

"I'm going to make money for you. Yang Xiaoman picked up his brand-name bag and said gently: "Help me keep dinner in the evening." ”

"You don't eat breakfast?" Xu Mang frowned and asked, "Skipping breakfast is not good for your stomach." ”

"It's too late!"

"You last night... It's like a neurotic. Yang Xiaoman glanced shyly, and then left the apartment in a hurry.

At this point,

Xu Mang has become an empty nest youth in the true sense of the word, and the class has been completed, the gravitational wave detection work has been solved with unsolvable problems, and the probability problem of quantum mechanics cannot continue because of the laser equipment.

"The system... Am I thinking right about experimentation?"

[Recognized by the system, whether the experimental thinking is correct to exchange value: 1 (physical skill)]

Pay!

[Correct]

Hemp eggs!

You're a spy sent by the white cat, right?

"The system... What should this laser look like?"

[Recognized by the system, the correct exchange value of the laser device: 5000 (physical skill)]

Pay!

【Laser mesh lattice】

Followed by

Xu Mang received the specific parameters of the so-called laser grid lattice, a crystal composed of thousands of precisely arranged atoms.

"I see!"

After understanding the so-called laser mesh lattice, Xu suddenly realized that since each atom in the lattice behaves similarly to other atoms, the measurement of the entire atomic population reveals the possibility of a single atom at a certain point in space.

Xu Mang sighed and looked at his notebook silently.

Saying

It's been a long time since I've had a happy liver burst.
