Volume 1 Chapter 160 Extra: She Toyed Me Again
"Some people may have heard the phrase, 'When in doubt, use quantum mechanics.' So, what exactly is quantum mechanics..."
Du Ruo uses concise words to talk about the origin of quantum mechanics, gradually going deeper, with rigorous logic and clear explanations, combined with carefully crafted PPT courseware, leading everyone step by step into the mysterious field of quantum mechanics.
Even people like Ji Yunbai and Wen Fei, who had never met the artist before, were deeply attracted and listened with great interest.
Nearly 600 students gathered in the lecture hall, not all of them were physics majors, and almost half of them came there out of curiosity.
However, at this moment, the entire lecture hall was unusually quiet, with only Du Ruo's soft and pleasant voice echoing in the air. She was like a shining star in the universe, shining brightly. Everyone could not help but follow her rhythm with full concentration, walking towards a world full of mystery and exploration.
Xu Jingmo sat leisurely in the audience, leaning back in a relaxed manner, with a smile in his eyes, looking tenderly at Du Ruo on the stage. His heart was beating restlessly, and his deep eyes seemed to only be able to accommodate the figure on the stage, and he was firmly attracted to her.
A few minutes passed quickly, and as the break bell rang, the quiet lecture hall became noisy again.
Du Ruo's assistant Xiao Qian walked into the lecture hall, handed her a thermos cup, and talked to her quietly while holding her diary.
Du Ruo gently twisted the lid of the cup, sipped the health-preserving tea, and at the same time lowered her head to check the messages on her mobile phone. She occasionally nodded in response to Xiao Qian's words, but never cast her eyes on the audience.
The students' movement blocked Xu Jingmo's view, so he looked down at his phone and sent a WeChat message to Du Ruo.
[Do you have any other plans after class? ]
Du Ruo replied quickly, "No plans, going home, what do you want to eat tonight? I can go to the supermarket to buy some groceries on the way."
【I want to go with you. 】
【Then I'll wait for you. 】
【good.】
[How was your first class? Teacher Xiao Du. ]
[Clear and stupid college students, they are still in control, (￣～￣)]
Seeing her arrogant and coquettish tone, Xu Jingmo just thought she was extremely adorable and couldn't help laughing out loud.
The laughter caught the attention of Ji Yunbai, who turned to look at Xu Jingmo.
Xu Jingmo took off his duckbill cap and casually hung it on his wrist. He was wearing a mask, so Ji Yunbai couldn't see his expression clearly, but his narrow eyes were filled with a doting smile.
Ji Yunbai looked up at the podium again, only to see Du Ruo looking down at his phone with a relaxed smile on his face, completely different from the serious and expressionless image he had just had on the stage.
He turned to Wen Fei and said, "Now I really understand what Ah Mo meant when he said that we are benefiting from his influence. Without him, we would never meet someone like my sister in our lifetime. Even if we had the chance to meet her, my sister would definitely not pay any attention to us. She would ignore us completely."
Wen Fei had been concentrating on secretly taking photos of Du Ruo, with stars in her eyes. She casually agreed, "Oh, my sister is just too strict about gender. If she likes girls, what's the use of Ah Mo..."
“…”
“…”
As soon as she finished speaking, she realized that she had said what was in her heart. She turned her head awkwardly and saw two speechless faces with dissatisfied looks in their eyes.
"You have a nice idea."
Ji Yunbai and Xu Jingmo used the same sarcastic line, but the tone and meaning were completely different.
Wen Fei smiled awkwardly, "I was just sighing casually."

The break ended quickly, and the bell for class rang. Du Ruo continued his speech on the same topic.
The first half of the class covered the history of quantum mechanics, and the second half focused on the core concepts and practical applications of quantum mechanics. Starting from the basic principles of quantum mechanics, key concepts such as wave-particle duality, quantum entanglement, and uncertainty were explained in detail. The content became increasingly profound and difficult to understand, especially when some calculation formulas and complex mathematical derivations appeared on the screen, which made non-professional students even more confused.
But Du Ruo explained these complex theories using very intuitive and everyday metaphors.
"If you have a coin and you throw it up in the air, it can come down heads or tails, which is a simple duality. But in the quantum world, the coin can be heads and tails at the same time before it is observed. This is wave-particle duality."
"For example, if you have a pair of gloves and you give one to your friend, no matter how far away you are, when you open your glove box and find that it is a left glove, you will immediately know that your friend's glove must be a right glove without any communication. This is the entanglement phenomenon."
"So what is the uncertainty principle? Imagine you are trying to measure the position and velocity of an electron. It's like trying to take a picture of a moth with a flash in a dark room. The flash will disturb the moth for a moment, so you can't know both its position and velocity at the same time."
Her vivid metaphors made everyone in the lecture hall sigh and say, "Oh..."
As the course progressed, the obscure theoretical knowledge in the courseware seemed to come alive, and the students' interest was thoroughly aroused, as if physics was no longer the abstruse physics in textbooks, but was closely related to our real life.
After Du Ruo finished talking about some practical applications of quantum mechanics, he looked at his watch and saw that there were still five minutes left before the class ended.
"The next five minutes are for free questions. Does anyone have any questions?"
In an instant, many arms were raised like a forest.
Du Ruo randomly selected students from each row to answer the questions.
Most of the questions were about some difficult to understand content discussed in class. Du Ruo's answers were quick and clear, and soon it was his turn in the middle position.
Her eyes swept across the students who raised their hands, but were attracted by three furtive figures.
The two were looking down at their phones, seemingly trying hard to seem invisible.
The other one was wearing a hat and a mask, wrapped up tightly, but he looked back at her with unusual calmness.
Du Ruohan paused for a moment, met Xu Jingmo's eyes, and couldn't help but raise the corners of his mouth slightly. He coughed lightly and pointed to a student who raised his hand sitting next to Xu Jingmo.
"Teacher, I would like to ask which theory your latest RM inequality is based on?"
As soon as the classmate finished asking the question, the bell for the end of class rang, but no one in the classroom was in a hurry to leave. Everyone was waiting for Du Ruo's answer.
Du Ruo, who had been expressionless all this time, suddenly raised his lips, and his voice seemed to carry a hint of teasing, "The student wearing a hat next to you, do you know what theory the RM inequality is based on?"
The 'student in the hat' shook his head slowly.
Du Ruo said slowly, "I don't know... Then why not ask your family before you come to the class next time, so as to avoid being embarrassed when you don't know anything? What do you think?"
Xu Jingmo held his forehead helplessly, thinking, he knew she wouldn't let him go so easily.
Du Ruo's words were so eye-catching that everyone looked towards that row of seats.
Xu Jingmo blocked it so tightly that it was hard to tell for a moment, but Ji Yunbai and Wen Fei beside him did not hide it at all, and many people knew that they were mutual friends.
Before the noise in the lecture hall started, Du Ruo looked at the student who had asked the question and replied, "The detailed theory and application of the RM inequality is what I will explain in the next class. Let's just leave it as a little suspense and not reveal it for now. Students who are interested, see you next week. Class dismissed."
Du Ruo quickly put away the courseware and left through the side door without hesitation.
Xu Jingmo was stuck in the middle of the seats. The classmate who had just asked the question looked at him excitedly and asked, "You are Teacher Du Ruo's boyfriend, right? Right! Right! Oh my God, I finally saw him alive!"
Xu Jingmo looked at the curious eyes of the people around him and said decisively, "Hey... classmate, cover me out and I'll add the teacher on WeChat for you."
The boy immediately said, "Is there such a good thing? Oh my god, I'm going to buy a scratch ticket later. How lucky am I today?"
With Ji Yunbai and the boys helping to block him from both sides, Xu Jingmo successfully escaped from the classroom.
He looked at the students behind him who were almost treating him like a monkey and surrounded him. He let out a long sigh, licked his teeth in anger, opened WeChat and asked, "Where are you?"
The other side quickly replied, "Office, come on."
Xu Jingmo walked towards Du Ruo's office with ease, looked around the corridor, knocked on the door, and then pushed it open. However, he was stunned for a moment, obviously not expecting so many people in the room.
He thought that Du Ruo told him to come so directly that it meant that no one was there.
He stood at the door, not knowing what to say for a moment.
Several physics teachers in the office did not know him and asked in confusion, "Student, who are you looking for?"
Xu Jingmo stared at Du Ruo with resentful eyes.
Du Ruo had a mischievous smile in her eyes. She picked up her backpack and walked towards him. She took his hand and said to everyone, "I'm your family. I'm here to pick me up from get off work."
The corners of Xu Jingmo's lips curled up unconsciously. OK, I've been played by her again. Who told her to be so good?
