Reshaping life starting from the Junior Class of HKUST

Chapter 135 Quantum Field Theory
When Academician Zhou stepped into the classroom, Wu Zhe had almost sorted out the instructions.

Academician Zhou Bangxian is not tall, around fifty.With glasses on his face, he was dressed casually.

I came in and looked around, and started directly without calling names.For quantum physics, some people are confused after hearing it.

"Students, everyone knows that unlike a stone at a certain location, on a microscopic scale, a particle actually has no location, and its existence is more or less distributed throughout the entire space. This description of particles are probability waves, 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 often disappear, just like photons are absorbed by electrons in atoms.Second, quantum mechanics treats each particle independently.But e is not equal to e in a family of particles such as the electron,--
But many characteristics indicate that e is equal to e, so to answer this question, a new mathematical framework is required, and then quantum field theory is created.
-
The establishment of quantum theory is based on classical field theory, special relativity and quantum mechanics.

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

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

Having said that, Academician Zhou paused for a moment to let everyone think about it. Quantum physics is like this. If you can't figure it out, you will never be able to figure it out.

Both Wu Zhe and Tang Meng are the best of the best, and they understand without any sense of disobedience.

This is an addition to quantum mechanics.Wu Zhe is still thinking about the relationship between these vectors, and even thinks about the problem of turbulence, and then leads the problem to the Young-Mills equation problem among the millennium problems in the mathematics world.

Seeing Wu Zhe's eyes fluctuate, Tang Meng pushed Wu Zhe down.He asked in a low voice, "What did you think of?"

Wu Zhe shook his head lightly, then smiled and said in a low voice: "There are a lot of things that can be associated. If you want to write papers, you can write several papers. I am not afraid of my physics graduation thesis. I should be able to write several papers on SCI."

Tang Meng rolled her eyes at Wu Zhe, and she also knew that Wu Zhe would not write a paper specifically, and if he published a paper, there must be something to say.

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

Tang Meng nodded.

Academician Zhou just started to explain the part of quantum field theory.After two classes, nothing happened, Wu Zhe listened with great interest, and planned to go to the Institute of Physics to attend lectures after returning to HKUST.The school of physics in his own school is stronger than Mizuki, and it is estimated that the school of physics of Beijing University can compare with it in China.

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

"Hmm! Ah Zhe, where are we going?" Tang Meng asked Wu Zhe with a smile behind her hands.

"Hey hey, today's Christmas Eve, I'll take you to a good place. Although I don't like foreign festivals, but it's just in time, so I can join in the fun."

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

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

Tang Meng smiled, then tilted her head and said to Wu Zhe, "Where did you get the bicycle book! It looks like the young lady's bicycle. Hurry up and ask for it."

"I just borrowed it, hurry up, and I have to return the car?" Wu Zhe urged Tang Meng to get on the car without asking who borrowed it.

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! Are you Mizuki popular with women and men?"

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

Fine!How can I sit?Wu Zhe was a little hesitant. He sat sideways like a girl, or sat with his feet on both sides. The back row is shorter. Anyway, it seems that sitting is not normal!

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

"Hurry up, I haven't ridden a bike for a long time. Let me tell you, Ah Zhe, I've never taken a boy!" Tang Mengjiao said with a smile.

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

Tang Meng wobbled while riding, but stabilized immediately.Wu Zhe also put his hands on Tang Meng's waist.

It feels good, at least that's what Wu Zhe thinks. 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 was guiding 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 made Tang Meng stop.

"Azhe, did you borrow the car here?" Tang Meng asked curiously.

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

"Let's go in together! Let's see which young lady borrowed it from you." Tang Meng said narrowly.

"Then let's go in together! It belongs to a sales lady, but I borrowed the car from their manager." Wu Zhe also explained.

Tang Meng was just joking with Wu Zhe.

The two entered the sales office hand in hand. After finding the salesperson, Ms. Li, they returned the key to her.Wu Zhe also thanked him repeatedly, which made Xiao Li bow and return the salute all the time.

After leaving the sales office, Tang Meng said to Wu Zhe: "That Miss Li, I treat you very respectfully! Hey, Wu Zhe, what are you hiding from me?"

"Let's go! We'll know later?" Wu Zhe took Tang Meng's hand and entered Qingfeng Huajingyuan Community.

"Why did you bring me here! Ah Zhe, you bought a house here?" Tang Meng is so smart.

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

At least don't think about hiding anything, so Wu Zhe is also very honest, pretending to be depressed and said: "Mengmeng, can you pretend that you don't know? I want to surprise you."

Tang Meng glanced at him coquettishly, shook the hands they were holding, pushed her chin forward twice and said: "Lead the way ahead and see Ah Zhe's new house."

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

"Azhe, what are you doing? Take me in and have a look." 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 let go only after walking through the porch.

The orange light shines on the surrounding bookshelves, and the surrounding furnishings reveal elegance and tranquility.

After Tang Meng was stunned for a moment, she immediately realized: "Is this borrowed from the St. Gallen Abbey Library in Switzerland?"

Wu Zhe also gave a thumbs up when he heard Tang Meng's answer.Being able to think of the source as soon as you see it shows that Tang Meng usually has a strong memory of his extensive knowledge.

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

"Well, I like it very much." Tang Meng murmured while leaning against Wu Zhe's arms.
