Chapter 194 How about trying tonight? (22)

Chen Ning was too lazy to cook at noon, so she ordered a takeaway with Lai Xiaomeng, and then turned on the class mode. According to the plan, the physical formula of the little woman should have been checked in the morning, but now it has been moved to the afternoon, but there are new arrangements in the afternoon.

"Our time is very tight." Chen Ning said seriously: "It's one pm now, and there are only two hours left for us, because there is a public online class by Academician Xu Mang."

"oh"

Lai Xiaomeng sat obediently at the desk and asked curiously: "What is Academician Xu Mang's public class talking about?"

"Computing the high-circle Feynman diagram in quantum field theory!" Chen Ning said seriously: "This is one of the core problems of high-energy physics. The reason is that the calculation of the circle diagram of quantum field theory will become extremely complex as the number of outer lines and circles increases. What Academician Xu Mang wants to talk about is his view on such problems."

At this moment,

Lai Xiaomeng was a little confused. She couldn't even understand high school physics. Now she was going to listen to the high-circle Feynman diagram in the quantum field theory. Isn't this just because she didn't learn to walk and started soaring in the sky.

"no."

"Do you overestimate me?" Lai Xiaomeng pouted and said angrily: "I don't even know what a high-circle Feynman diagram is. There is also a quantum field theory, you. Just let me listen to this."

"oops"

"Let me listen to it, Academician Xu Mang broadcasts his open class online for the first time. What a rare opportunity." Chen Ning said with a smile: "Maybe you suddenly become interested in physics as you listen. This is also something that may happen. Just listen. OK?"

"."

"Okay, okay." Lai Xiaomeng nodded and said calmly: "What about now? What are you doing now?"

"Spot check your physical formula." Chen Ning said maliciously: "I won't ask some very basic questions. If you want to write a certain formula, you will definitely remember it. I will ask you to write it out. How a formula is extended and what the theorem is."

After the words,

Chen Ning put away her smile and said seriously: "Prepare the paper and pen. Let's get started."

Lai Xiaomeng pouted her little mouth, her face full of displeasure, but she didn't dare to act rashly at this moment. She would just let go of her temper. If she was a little bitch at this time, she would definitely make the stinky man in front of her unhappy. The quarrel would be small at that time. If she didn't do it well, she would have a cold war.

Then,

Chen Ning asked a few relatively simple questions, and Lai Xiaomeng lived up to expectations. She described all these questions in a short time, which made her look proud, and at the same time she was waiting for Chen Ning's praise.

"how?"

"Is this a complacent person?" Chen Ning said with a smile: "If you only test these contents in the college entrance examination, then you are indeed fine, but you don't just test these. There are deeper contents, and those contents must be obtained to ensure that they are foolproof."

Hearing Chen Ning's words, Lai Xiaomeng suddenly felt relieved and sat there angrily without saying a word, waiting for the next test.

soon,

Chen Ning gave the little woman a few more questions. Compared to the previous difficulty, she was obviously confused. She either tilted her head and thought about something, or used the black pen in her hand to scratch the original content, and repeatedly

"Time is up!" Chen Ning suddenly spoke.

"ah?"

"No. This. Is there a time limit?" Lai Xiaomeng suddenly came to her senses, looked at Chen Ning with dissatisfaction, and pouted her mouth and said angrily: "I have just written two questions."

"Of course there is a time limit."

"Do you think you'll give you a day and let you think about it slowly?" Chen Ning said angrily: "These contents must come to your mind instantly. There can't be any thoughts. I still say that no matter how hard or tiring the process is, it must be the result I said."

After saying that,

He reached out to get the draft paper of Lai Xiaomeng, looked at it casually and said helplessly: "It's a terrible sight."

"I"

"I can only do this for the time being." Lai Xiaomeng lowered her head, and her words were filled with sad feelings, and she said softly.

Looking at the little woman who was in sorrow, Chen Ning opened her mouth to criticize her, and swallowed it back, reached out and touched her head gently, and said gently: "Okay, okay. Let's work hard next time."

"oh"

Although Lai Xiaomeng was still a little sad inside, she felt a little sweet at the same time. I have to say that when he touched his head, the gentle feeling was really addictive.

At 3:00 pm,

Chen Ning finally waited for his idol's live open class, and Lai Xiaomeng sat next to him, looking at a middle-aged man appearing on the tablet, and couldn't help feeling a little confused. He was obviously a great scientist, but why did he have a temperament that was not a good person?

"Is this Academician Xu Mang?" Although Lai Xiaomeng has seen photos online, it was the first time he saw them through the live broadcast. He said curiously: "Why do I feel like he is a little naughty?"

"His wife, Ms. Yang, once broke the news on a TV show. Academician Xu Mang was nicknamed Pipixia when he was a child." Chen Ning said with a smile: "Kepi Kepi had exploded the school septic tank when he was in high school."

"ah?"

"This." Lai Xiaomeng looked at Academician Xu Mang, who was known as the God of Physics, on the screen with horror. He could not imagine that such a successful scientist had done such an incredible thing when he was a child.

"Shh!"

"It's beginning!"

Chen Ning hurriedly corrected her attitude and listened to the live broadcast content seriously. At the same time, Lai Xiaomeng didn't dare to speak anymore, sat obediently on the side, pretending to be listening to the class.

"Generally in gauge theory, physical quantities satisfy normative symmetry and space-time symmetry, but in gravitational theory, the symmetry that physical quantities satisfy is only space-time symmetry."

"Someone will definitely ask here. There is a close connection between normative symmetry and space-time symmetry. Are physical quantities in normative theory and gravity theory also have a close relationship? In fact, we can directly construct gravitational amplitude from the normative amplitude that satisfies the duality."

"Then replace the color factor with the momentum factor, so that the amplitude contains the square of the momentum factor, and it is also the gravitational amplitude."

"certainly!"

“There is a condition here.”

At this moment, Lai Xiaomeng was confused and had no idea what this world's top scientist was talking about, just like listening to the heavenly book. Sometimes it was symmetry, sometimes it was symmetry in time and space. Can't it be unified? It was so complicated.

He secretly turned his head and glanced at Chen Ning on the edge of his eyes with the corner of his eyes. He found that he was focused on looking at the tablet computer in front of him. The more meticulous he was, the more serious he was.

He pursed his lips and couldn't help but smile bitterly.

Why.

This world of the God of Learning is simply terrible!

Gradually,

Lai Xiaomeng's attention was moved from the tablet computer to the man beside her, and then her head began to think about it. In a moment, a touch of beautiful red cloud was slowly engraved on Junrou's face.

Sudden
