When Academician Zhou stepped into the classroom, Wu Zhe also sorted out his pointers.

Academician Zhou Bangxian is not tall, about fifty. He wears glasses on his face and dresses very casually.

I came in and looked around, and I didn't name names, but started directly. Some people are confused about quantum physics.

"Students, as we all know, unlike a stone in a fixed position, on a microscopic scale, the particle actually has no position, and its existence is more or less distributed throughout the space. This description of a particle is a probability wave, known as quantum mechanics. The evolution of particles over time. ------

But what quantum mechanics can't describe is that particles evolve over time, but in reality particles disappear frequently, just as photons are absorbed by electrons in atoms. Second, quantum mechanics treats each particle independently. But in a group of particles such as electrons, e is not equal to e,------

But many properties mean that e is equal to e, so to answer this question, a new mathematical framework is required, and quantum field theory is created.

------

Quantum theory is based on classical field theory, special relativity, and quantum mechanics.

The physical properties of a classical field can be described by quantities defined in space (e.g., the properties of an electromagnetic field can be described by the strength of the electric field and the magnetic field, or by a three-dimensional vector potential and a scalar potential).

These field quantities are a function of spatial coordinates and time, and their variation over time describes the motion of the field. The quantities of fields at different points in space can be regarded as dynamic variables independent of each other, so the field is a system with continuous infinite-dimensional degrees of freedom. ”

Speaking of this, Academician Zhou paused for a moment, so that everyone can think about it, this quantum physics is like this, if you can't figure it out, then you will never be able to figure it out.

Wu Zhe and Tang Meng are both top students among the top students, and the two understand that there is no sense of disobedience.

This is a complement to quantum mechanics. Wu Zhe was even thinking about the relationship between the vectors, and even the turbulence problem, which led him to the Young-Mills equation problem in the millennial puzzle of mathematics.

Seeing Wu Zhe's eyes change, Tang Meng pushed Wu Zhe down. Whispered, "What do you think of?" ”

Wu Zhe shook his head slightly, and then said with a smile and in a low voice: "There are a lot of things that can be associated, if it is a water paper, it can be a few water papers, my physics graduation thesis is not afraid, I should be able to write a few SCI papers." ”

Tang Meng glanced at Wu Zhe, she also knew that Wu Zhe would not specialize in water papers, and if he published a paper, it would definitely be something to say.

Wu Zhe spoke again at this time: "This quantum field theory is very useful for condensed matter physics and nuclear physics!" ”

Tang Meng nodded.

Academician Zhou also began the explanation of this part of quantum field theory. After two classes, nothing happened, but Wu Zhe listened to it with relish, and planned to go to the Institute of Physics to listen to the lectures after returning to the University of Science and Technology. The institute of things in his own school is stronger than Mizuki, and it is estimated that the institute of things in Beijing can be compared in China.

"Let's go!" Wu Zhe helped Tang Meng pick up his schoolbag.

"Hmmm! A-Zhe, where are we going? Tang Meng asked Wu Zhe with a smile behind his back.

"Hey, hey, it's Christmas Eve, I'm going to take you to a good place. Although I don't like the festival, it's just in time, and it's all in the fun. ”

After listening to Wu Zhe, Tang Meng frowned lightly and said, "There will be a lot of people tonight, I don't want to go out and squeeze." ”

"Take it, I won't let you go out and squeeze it." Wu Zhe gave his schoolbag to Tang Meng and went to push the bicycle himself.

Tang Meng smiled, then tilted his head and said to Wu Zhe: "Where did you get your own book!" This look is the young lady's bicycle. Hurry up and recruit from the truth. ”

"I'll borrow it, hurry up, and I have to return the car to others?" Wu Zhe didn't say anything about asking who borrowed it, and urged Tang Meng to get in the car.

Tang Meng grabbed Wu Zhe's clothes, pulled them back, and said, "I'll come, you sit in the back." ”

Wu Zhe was stunned and said: "This is a bit bad!" You Mizuki pop women with men? ”

"What nonsense, take it." Tang Meng handed the schoolbag to Wu Zhe again.

Let's go! How can you sit? Wu Zhe was a little hesitant, sitting on his side like a girl, or sitting on both sides with his feet on his feet, this back row is shorter, anyway, it doesn't seem normal to sit!

"Mengmeng, why don't we walk!" Wu Zhe said a little weakly.

"Hurry up, I haven't ridden in a long time. Tell you Ah Zhe, I've never taken a boy before! Tang Mengjiao said with a smile.

Die and die! Wu Zhe closed his eyes and sat sideways in the car.

Tang Meng rode shaky, but immediately stabilized. Wu Zhe also took advantage of the situation and put his hands on Tang Meng's waist.

It feels good, at least that's what Wu Zhe feels, as for the surprised eyes of passers-by, Wu Zhe automatically thinks that the other party is envious and jealous.

The two walked out of the school gate leisurely, Wu Zhe showed the way behind, the community was not far from Shuimu, and they arrived at the sales office after a while.

Wu Zhe got out of the car and asked Tang Meng to stop.

"Ah Zhe, the car you borrowed here?" Tang Meng asked curiously.

"Hmm. I'll go and get off, you wait for me. Wu Zhe said.

"Let's go inside! Let's see which young lady borrowed you. Tang Meng urged the narrow road.

"Let's go in together! It's a sales lady, but I asked their manager to borrow the car. Wu Zhe also explained.

Tang Meng was just joking with Wu Zhe.

The two walked into the sales office hand in hand, and after finding Miss Li, the salesman, they returned the key to her. Wu Zhe also thanked him again and again, so that Xiao Li kept bowing and returning the salute.

After leaving the sales office, Tang Meng said to Wu Zhe: "That Miss Li, I am very respectful to you!" Hehe, Wu Zhe, what are you hiding from me? ”

"Let's go! You'll find out later? Wu Zhe took Tang Meng's hand and entered the Qingfeng Huajingyuan Community.

"What did you bring me here! A-Zhe: Have you bought a house here? "Tang Meng is so smart.

Wu Zhe knows the IQ of himself and Tang Meng, and there are no surprises in many times in life.

At least don't think about hiding anything, so Wu Zhe was also very honest, pretending to be very depressed and said, "Mengmeng, can you pretend not to know?" I'd like to surprise you. ”

Tang Mengjiao glanced at him with disgust, shook the hand held by the two, and said twice with his chin: "Lead the way in front and take a look at Ah Zhe's new house." ”

Wu Zhe led Tang Meng to the top floor of Building Six. Wu Zhe pressed the fingerprint lock, then took Tang Meng's hand and set her fingerprint as a password.

"Ah Zhe, what are you doing? Take me inside. Tang Meng urged.

Originally, Wu Zhe could see the hall when he entered the door, but later Wu Zhe added a porch.

Wu Zhe covered Tang Meng's eyes and walked through the entrance before letting go.

The orange lights hit the bookshelves around them, and the surrounding furnishings exude elegance and quietness.

Tang Meng was stunned for a moment, and immediately reacted: "This is borrowed from the St. Gallen Monastery Library in Switzerland?" ”

When Wu Zhe heard Tang Meng's answer, he also gave a thumbs up. can think of the source as soon as you see it, which shows Tang Meng's usual erudition and strong memory.

"Do you like it?" Wu Zhe grabbed Tang Meng and kissed her lightly on the forehead.

"yes, I love it." Tang Meng leaned into Wu Zhe's arms and muttered.
