Chapter 112: Chapter 111 Quantum Entanglement
Last class, the professor talked about quantum entanglement.
Probably no one understood it, and Qi Yue was also half-confused.
“Hey! Classmate Qi, you’re here! Are you alone again?”
Upon hearing the greeting, Qi Yue looked up at the newcomer, physics genius Qii Shuhang, probably the only person in the classroom who understood the material. He was also one of the few who, like Qi Yue, had never missed a class. Over time, the two had become acquainted.
Qii Shuhang and his roommate He Ming sat down at the spot to Qi Yue’s right.
Qi Yue greeted them and then said with a sense of resignation, “Yeah, I tried to get my roommate to come with me, but all my attempts failed!”
...
“Haha! It would be weird if you had managed to persuade them! Quantum Mechanics is indeed hard to grasp, and girls who are interested in it are even rarer…” Qii Shuhang, looking at the book Qi Yue had opened, asked, “What were you so focused on just now? Have you come across another tough problem?”
Teasingly, He Ming interjected, “If you’ve hit a tough spot, just ask Shuhang, right? It’s a waste not to use a top student when you can!”
“Cut it out!” Qii Shuhang nudged He Ming with his shoulder, then scratched his nose and looked at Qi Yue, “Which part don’t you understand?”
Qi Yue sighed, “It’s the content from the last class that the professor talked about; I still don’t quite get it…”
“Quantum entanglement? It’s actually quite simple to understand. Imagine a neutral pi-meson with zero spin decaying into an electron and a positron. These two decay products then move away from each other in opposite directions…”
Qii Shuhang indeed had a solid grasp of the subject and began to explain fluently, but, unfortunately, Qi Yue did not understand much…
After all, explaining Quantum Mechanics can be just as difficult as learning it.
Perhaps noticing that Qi Yue was not following, Qii Shuhang gave a slight cough and changed the subject, “Classmate Qi, have you ever heard this idea? That when two particles become entangled and move far apart, the behavior of one particle can affect the state of the other. So, there’s this theory that if someone misses you enough, they could appear in your dreams…”
Qi Yue thought for a moment and said, “I think I have heard of it. Although it’s just a hypothesis, it’s quite a romantic notion…”
At this point, Qi Yue inexplicably thought of the dream she had that morning…
“Right…” Qii Shuhang scratched his head, looking somewhat embarrassed, and hesitantly said, “Classmate Qi, actually I…”
Before Qii Shuhang could finish, the warning bell rang.
Then, a series of steady and brisk footsteps was heard at the classroom door.
Breezes wafted peach blossom petals from the branches, which floated into the doorway, and a few landed on the shoulders of the newcomer.
Qi Yue, without meaning to, looked up and saw the person in a familiar white shirt with a simple coat draped over it, walking step by step into the classroom amidst the lively springtime…
In the classroom, a few scattered students all gasped in unison, instantly awakening from their drowsy state.
Qii Shuhang stared in disbelief at the person at the door, “Holy shit! Hugh… God Xiu?”
He Ming, too, widened his eyes in shock, “It’s really the bigshot! What’s he doing here? Did he also enroll in this course?”
Qii Shuhang said exasperatedly, “Don’t you have any common sense? The bigshot’s main focus at HF is Quantum Mechanics, and he has even lectured on it. With his level of expertise, why would he come here to attend an introductory college course? Isn’t this like a high-level player grinding for experience in a newbie village? It’s just a waste of time, isn’t it?”
He Ming slapped his forehead, “Right, now I remember. Could it be that the bigshot is here to substitute teach?”
