Chapter 355

In the milk tea shop, the couple seemed to notice that there were two people watching the show next door and had already left with their milk tea.

Can't reason, so have a fight?

Ding Jiahui blinked and said somewhat uncertainly: "Yaoyao, quarreling is quarreling, but moving hands... isn't that a bit too much."

She found that her best friend was becoming more and more unconventional.

"Is it too much?"

"Isn't it too much?"

"."

Song Yao thought in her heart: "It's not too much after the clothes accidentally fall off while fighting."

But this kind of little fun between couples naturally cannot be said casually.

She thought about it and said: "In short, two people who like each other should say what they think clearly, and not hide it."

Unknowingly, Song Yao and Ding Jiahui's identities as dog-headed military advisors were swapped.

"Yeah." Ding Jiahui deeply agreed. She was sulking here, not saying anything, how could the problem be solved.

She thought of something more important: "Yaoyao, you and Xu Qingzhou, never quarreled, wouldn't it be that you often solve it by fighting?"

"No..."

Song Yao shook her head. She and Xu Qingzhou really didn't have any conflicts.

Moreover, fighting requires both sides to be evenly matched, and the cheap and cowardly Xu Laoshi is unilaterally sanctioned.

At this time, Yandongyuan, Xu Qingzhou, who was leisurely brushing videos, suddenly felt a chill rise on his back.

Song Yao pushed the door and entered, seeing that Xu Qingzhou was even earlier than her, and even finished showering, holding a tablet to look at materials.

"I'm back."

"How was the movie?" Xu Qingzhou nodded.

Song Yao went to watch the movie "Partners" with Ding Jiahui in the evening.

"Ugly." Song Yao evaluated.

"Very accurate." Xu Qingzhou agreed, he had seen it once before, and almost fell asleep halfway through.

"You didn't watch it."

"I read the reviews online."

Xu Qingzhou found a reason casually and said without raising his head.

He was looking at the latest information in the mathematics world. A postdoctoral researcher at the Berlin Mathematical School and Humboldt University of Berlin proved that in 8-dimensional space, E8 is the densest packing of spherical objects. This discovery has important significance for understanding geometric structures in high-dimensional space.

Three scholars, Bourgain, Demeter, and Guth, jointly solved the proof of Vinogradov's Mean Value Theorem, which is a theory about the number of positive integer solutions to systems of equations. The three scholars introduced elements of harmonic analysis.

In just a while, he had finished reading the content of the Mean Value Theorem.

These three scientists introduced theories such as Fourier transform, wavelet analysis, operator theory, etc. Besides things in harmonic analysis, they also used number theory variational methods, partial differential equations, etc.

In physics, the Mean Value Theorem can be used to study phase space density distribution in quantum field theory, particle collision cross-sections, etc., while in economics, it can be used to analyze the volatility of financial markets, trends in stock prices, and so on.

"Back so early today?" Song Yao had already changed her slippers and walked over with a kick and step.

"Just ate a meal, didn't even drink much wine."

Xu Qingzhou said with a smile.

After two years of tempering, the three in 101 were no longer the greenhorns they were at the beginning, holding wine bottles and drinking, not swearing to stop until the other party was drunk.

Gradually became a health-preserving session.

After a meal, the four of them didn't even finish a case of beer.

Song Yao sat down on the side, collapsed into Xu Qingzhou's arms, and sniffed on his pajamas. This guy really didn't have much smell of alcohol on him.

"Get up, you're crushing me to death." Xu Qingzhou helped the girl sit straight.

Song Yao sat, glared at Xu Qingzhou resentfully, and plunged into his arms again.

"Xu Laoshi, thank you." The girl in his arms murmured. Chatting with Ding Jiahui today, she realized that it had always been Xu Qingzhou conceding.

Feelings are something that requires both sides to pay. She felt that she needed to be a bit "weak."

Xu Qingzhou was stunned. It was already June 10th, the menstrual period had long passed, how did she suddenly come up with this?

Song Yao looked up and asked: "Am I very much like a tomboy, not gentle at all."

"Of course not, you are the best to me." Xu Qingzhou said with a very certain tone, but sighed inwardly that the School Beauty had a very clear positioning of herself in this aspect.

"Really?"

"Completely sincere."

Song Yao put her face back on his chest: "Then praise me, regarding gentleness."

"Gentle and considerate, reasonable..." Xu Qingzhou recited insincerely, while simultaneously imagining the appearance of the School Beauty clenching her fists, "Gentle and virtuous, independent and introverted, fierce and vicious..."

Xu Qingzhou's voice stopped. What did he just say last?

Song Yao was enjoying Xu Qingzhou's praise of her, and also discovered that there seemed to be something strange mixed in these words. She left Xu Qingzhou's arms, "What did you just say?"

"I'm praising you, wait, hiss~"

So, the School Beauty, who originally wanted to pretend to be a bit gentle, ravaged her boyfriend on the sofa for a long time before happily going to take a shower.

Mid-June.

Song Yao's TOEFL scores came out, no surprise, a high score of 117.

Xu Qingzhou was also in an orderly manner, collecting corresponding data.

The computer was humming, and lines of complex characters slid across the screen.

Xu Qingzhou was currently preprocessing the raw data from last week, including noise removal, filling in missing values, data smoothing, etc.

And he himself was calculating the probability of finding electrons.

The probability of finding an electron at d is: p(d|ψ(d, t)|2^2\\=n^2|e^{-iet

Let the momentum of the incident electron be p, then in the momentum representation of the electron at t=0, the probability amplitude of the electron momentum p reaching point d on the observation screen along path p in Figure 1 is:

k(p, t) = ￡)ψ(y, 0)

Restricting the particle to a circular ring, the particle's wave function only depends on the azimuth angle, i. e., (o=π/2, r=b)(, so the stationary Schrodinger equation can be written as a constant coefficient linear differential equation.

Unlike Song Yao, who was stared at by Professor Li to do various projects, Xu Qingzhou was completely in a free-range mode.

The project of Chu Jiangfeng and Yang Yongze reached the later stage, and on June 27th, they flew to the UK to participate in academic exchanges.

The AB effect reflects the coherence of quantum particles, i. e., the wave functions of particles on different paths can interfere with each other to produce observable effects. The phase relationship is mainly reflected in the phase of the wave function of the electron beam.

On July 14th, Xu Qingzhou had already tried to apply the wave function coherence model in the AB effect to quantum entanglement to establish a theoretical model describing the coherence of quantum entanglement.

This day, 5:00 PM, the sun was no longer as poisonous as at noon.

"Wait until next month, this month is a bit busy..." Xu Qingzhou dealt with Wang Nushi. As soon as the holiday arrived, Wang Nushi started calling to ask about going home for the summer vacation.

But he knew that Wang Nushi's visual fatigue period was three or four days.

"Auntie?"

"Yeah." Xu Qingzhou nodded. On the other end of the phone, Wang Xiaping seemed to hear Song Yao's voice and had already called Xu Qingzhou to hand the phone to Song Yao.

"We were just about to go eat... yeah, okay..."

3 minutes passed.

Song Yao returned the phone to Xu Qingzhou: "Auntie said to let me watch you, don't just know to stay up late all day." "I've already stopped staying up late."

"Also told you not to bully me."

"Fine, next time I'll just record a video of you beating me up."

"."

Having dinner together, Xu Qingzhou had to go to Professor Chang's side at night. He called Professor Chang at noon to say he wanted to borrow data.

Professor Chang had been participating in the quantum satellite experiment at the Quantum Research Institute.

There was only Qi Wanpeng, a student of Professor Chang Ziyuan, in the office.

"Xu Xu Shidi Xu, long time no see."

"Wang Wang Shixiong."

"Professor Chang went to Director Ji's side, have to wait a while, pour yourself some tea."

In one look

"Okay." Xu Qingzhou nodded with a smile. After sitting down, he asked: "How was the result of your experiment this time?"

As far as he knew, the Jingda project team was cooperating with the California Institute of Technology, planning to use quantum satellites in the Earth's gravitational field to attempt to combine quantum mechanics and general relativity for experimental verification.

Carrying out gravity-induced quantum entanglement decoherence experimental verification in space, testing the decoherence situation of entangled photons passing through the Earth's gravitational field.

"The experiment was very successful."

Speaking of this, Qi Wanpeng was suddenly spirited, "Through the experiment, we have completely excluded the gravity-induced entanglement decoherence phenomenon predicted by the theoretical model of the 'event form' stronger theory."

Xu Qingzhou recalled that this was a theoretical model proposed by an Australian physicist. According to the scheme prediction, in the propagation of entangled photon pairs in the Earth's gravitational field, their correlation would be lost probabilistically.

"Xu Xu Shidi, it's a pity you didn't come to participate in this experiment."

Speaking to the end, Qi Wanpeng felt emotional.

"I really couldn't get away." Xu Qingzhou said helplessly.

Couldn't get away, at the same time, he had done more complex experiments before.

Currently, the Mozi quantum satellite only has an orbital altitude of 500 kilometers and cannot yet conduct verification within the range of stronger entanglement decoherence predicted by the theory.

"We excluded the 'event form' stronger theoretical model, but there are other versions of theoretical models waiting to be verified. The road is long and difficult."

"Does Wang Wang Shixiong still believe in the possibility of the unification of general relativity and quantum physics?"

Xu Qingzhou asked with a smile.

"Believe!" Qi Wanpeng nodded affirmatively, "And, aren't there many gratifying achievements currently? Everyone is already focusing on the grand unified theory."

Xu Qingzhou felt emotional. This senior brother was indeed an idealist.

However, some physical scientists are indeed studying whether a grand unified theory can be constructed that can unify all basic forces.

The goal is to establish a mathematical framework that can unify the four basic interactions of electromagnetic force, weak force, strong force, and gravity, thereby providing a more comprehensive and complete understanding of the operation of the universe.

Qi Wanpeng asked: "Currently, the two candidate theories are superstring theory and loop quantum gravity theory. Xu Xu Shidi, which one are you more inclined to?"

Xu Qingzhou shook his head, "For these two theories, currently it seems there is no possibility of solving them. First, it is necessary to solve the inconsistency between general relativity and quantum mechanics in mathematical framework and physical assumptions."

"Secondly, it is necessary to find an effective method that can describe the quantization of gravity. Finally, it is also necessary to verify the correctness and reliability of these theories through experiments."

"Yeah, just the first step is already struggling." Qi Wanpeng sighed, and was a bit decadent again: "Almost can't see any hope."

"However, I believe that one day it will definitely be realized."

Xu Qingzhou was very optimistic and continued: "In my opinion, general relativity and quantum mechanics are like two painters with completely different styles."

"The former is good at using smooth, continuous lines and rich colors to depict a grand cosmic scene. The space-time under his pen is like a huge, soft canvas that can be bent and shaped by various objects and energy."

"Very accurate."

Wanpeng's eyes lit up, following Xu Qingzhou's logic, and continued: "Inside the canvas, galaxies, stars, and planets run according to precise, predictable orbits, as if being pulled by an invisible line. This line is gravity, and its source is the distribution of mass and energy."

"That's right, this painter can accurately calculate the position and speed of any object at any time, whether it is a distant galaxy or a planet close at hand."

"The latter is good at using tiny, flickering brushstrokes to depict the wonderful scenes of the microscopic world. In his paintings, particles, waves, and fields are intertwined, forming pictures full of uncertainty and probability."

"The particles under his pen seem to always be in a blurred state, both like waves and particles, until they are observed, they will suddenly 'choose' a determined state."

Now, let these two painters with completely different styles paint together.

The result is that their brushstrokes and colors will produce serious conflicts and be incompatible.

The two were talking when Professor Chang Ziyuan came back from a meeting.

"What are you two chatting about, so lively."

"Grand unified theory." Qi Wanpeng replied.

Chang Ziyuan shook his head, feeling very helpless about his student. The quantum satellite had only been in the sky for less than a year, yet he was fantasizing about the grand unified theory.

He didn't waste time either and said to Xu Qingzhou: "Can't explain clearly on the phone, come, tell us in detail about your experiment."

Xu Qingzhou briefly stated the content of his experiment.

"AB effect and quantum entanglement state..."

Chang Ziyuan fell into deep thought. After a long time, he nodded slightly and said: "This idea of yours is actually very novel, no one has considered it like this before."

"To be honest, the model is not perfect enough, and I currently cannot fully determine whether there can be a regular connection between the two."

"Doing scientific research requires constant exploration."

Professor Chang Ziyuan smiled gently, "As for data, there is basically no problem. After all, a considerable part of our entanglement data is open to foreign research institutions, so it's impossible to be stingy with our own people."

"That's fine."

"Do you really have no intention of focusing on physics?" Professor Chang Ziyuan couldn't help but ask. This kid is a natural seedling for physics, why did he go to the School of Mathematics?

Xu Qingzhou shook his head and said with a smile: "Better to lay a solid foundation in mathematics first."

After staying in the office for a while, Xu Qingzhou got up and left, intending to read for a while, pick up the School Beauty at night, and go home together.

At the same time, an advanced mathematics research institute in India.

"Hi, Amir, go for a drink together?"

The young man shook his head: "Sorry, compared to going to a noisy bar, I now want to do math problems quietly."

"Fine, you will miss a wonderful encounter."

Amir didn't commit, and soon, he was the only one left in the office.

He got up, poured himself a cup of coffee, and stood by the window to relax his brain. At this time, his competitor Xu Qingzhou was probably burying his head in hard work.

Amir's eyes were firm, the battle without smoke had long begun.

After months of struggle, he had already established square function estimation using bilinear oscillatory integral estimation, and also improved the local smoothness estimation of Fourier integral operators that can satisfy the film-type curvature condition.

Of course, the next part is one of the most difficult parts, converting bilinear square function estimation into bilinear oscillatory integral estimation.

"Phew~"

Taking a deep breath, Amir sat down at the table again, and his thoughts soon sank into the formulas in front of him.
