Chapter 155 Don’t Like Virtual Ones

One portion of fried rice, one portion of sweet and sour pork ribs, one portion of sword beans and potatoes, and a bowl of short ribs soup.

Such a set meal that was enough to satisfy Wu Bin actually cost only 10 yuan. Wu Bin paid special attention when browsing the food section and found that there were a lot of dishes that cost less than 60 cents. It can be said that he was too conscience-stricken. .

After sitting on the cushioned armchair, he saw Song Nanfeng sitting across from him move his chopsticks, and Wu Bin, who had barely eaten anything after walking around for a day, started eating.

Song Nanfeng looked at Wu Bin's eating appearance, smiled and shook his head, and also ate his own noodles.

"Wow... your eating habits are too exaggerated."

When Wu Bin stuffed two pieces of sweet and sour pork ribs and a big mouthful of fried rice into his mouth, a familiar young female voice suddenly came into his ears. He turned around and saw that it was Gu Ningshan who he had met in the afternoon.

After quickly chewing the food in his mouth and swallowing it in one gulp, Wu Bin waved and said hello: "Hi, what a coincidence."

"Hello, you saved Xiaobai, right? Thank you." At this time, another tall girl with a ponytail stood next to Gu Ningshan and greeted Wu Bin.

Seeing Wu Bin in a daze, Gu Ningshan said: "Let me introduce, this is Ding Yuhai from the Department of Chemistry, Senior Sister Ding, Xiaobai is currently staying in her home."

"Oh, hello, Senior Sister Ding." Wu Bin nodded towards Gu Ningshan.

Then when Gu Ningshan was about to introduce Wu Bin, she suddenly discovered that Song Nanfeng, who was sitting opposite, was looking at them in surprise. She said, "Hello, Professor Song." Then she pointed at Wu Bin and asked, "Huh? Professor Song, are you and me?" Is he together?"

Song Nanfeng nodded after listening and said with a smile: "Yes, I am taking him to visit the college. I am more curious about how you met."

After listening to Song Nanfeng's words, Gu Ningshan looked at Wu Bin in surprise and said, "Wow, are you so famous? You actually asked Professor Song to take you to visit the college in person."

After hearing this, Professor Song immediately said: "You don't know about the co-author, so let me introduce it to you. His name is Wu Bin. This year's CPhO champion has now joined the national team."

"Awesome, come on IPhO, senior sister is calling for you." Ding Yuhai gave Wu Bin a thumbs up.

Gu Ningshan on the side nodded thoughtfully and sighed.

"No wonder~"

At this time, Ding Yuhai suddenly reached out and touched Gu Ningshan's head, his face full of sweet affection.

"Senior Sister Ding~ Didn't I tell you not to touch my head all the time!" Gu Ningshan turned around and said helplessly.

"Who told you to be so cute when you think about problems? You can't help it." After saying that, Ding Yuhai suddenly looked at Wu Bin and said, "You think so too, right?"

"Is she cute..." Wu Bin shook his head, "I just think she's awesome."

Gu Ningshan and Ding Yuhai were stunned at the same time after hearing this.

"Of course Shanshan is awesome~ It doesn't stop her from being cute." Ding Yuhai said and pinched Gu Ningshan's little face again.

This time Wu Bin just smiled and didn't say anything. Ever since he discussed Carnot's theorem with Gu Ningshan on the bus in the afternoon, Gu Ningshan was no longer a little girl in his eyes, but a powerful person with knowledge beyond his. .

"Okay, what's the point of discussing this? Let's eat first~" Gu Ningshan, who had escaped from Ding Yuhai's "magic clutches", put down her dinner plate and sat next to Wu Bin.

"Is that all you eat?" Wu Bin couldn't help but ask, looking at the only bowl of porridge and two vegetarian dishes on Gu Ningshan's plate.

"I have a small appetite, and I don't like eating meat very much." Gu Ningshan replied.

"Oh." Wu Bin said and took two more bites of fried rice.

"Oh, by the way, Shanshan, what do you mean by that 'no wonder' you just lamented?" asked Ding Yuhai, who walked to the opposite side and put down his dinner plate and sat down.

Gu Ningshan took a sip of porridge and replied: "It's just that I saw him holding a book by Re Tong in his hand when he hugged Xiaobai. I originally wanted to give some guidance to this junior, but I didn't expect that he was all I have mastered the differential aspect, so in the end it was me and him who made a substantial evaluation of Carnot's theorem."

Ding Yuhai covered his mouth and snickered after hearing this: "Advice? I think you want to bully this junior."

Ding Yuhai could clearly tell that Gu Ningshan didn't know that Wu Bin had participated in the competition before, at least when she was preparing to chat with him about heat statistics, she just regarded him as a senior high school student visiting HKUST.

And if Wu Bin is just an ordinary high school student, even if he has good grades in high school physics, the thermal system in college can still easily make him doubt whether he has ever studied physics.

"Did you do something to make our Shanshan unhappy?" Ding Yuhai snickered and pretended to be serious while "questioning" Wu Bin.

"Me?" Wu Bin pointed at himself and shook his head, "No..."

"Oh~ I really wanted to talk to him because I saw her reading Re Tong's books." Gu Ningshan felt a little guilty when she spoke. After all, it can't be said that she wanted to talk to Xiao Bai because she envied Wu Bin for being able to attract Xiao Bai. Just bully him.

Seeing Gu Ningshan pouting her little mouth, Ding Yuhai stopped talking and lowered his head to eat.

After taking a sip of porridge, Gu Ningshan glanced at Wu Bin, who was still eating poorly. The corner of her mouth suddenly curled up and she asked, "Have you done any research on the Rutherford atomic model?"

"Yes, I have learned about it." Wu Bin nodded, "I read Fermi's beta decay theory before and found it quite interesting."

"You really see everything..." Gu Ningshan spread her hands, "Then you already know about weak power?"

Wu Bin's eyes lit up after hearing this. He quickly finished the remaining fried rice and started chatting with Gu Ningshan.

Seeing the two people opposite who were chatting about atomic models whenever they disagreed, Song Nanfeng smiled happily and had no intention of disturbing them.

After discussing for about half an hour, Wu Bin, who was chatting about the concept of exchange force, suddenly asked a question: "Actually, I have a question about gravity."

"Well, you can ask." Gu Ningshan's face was full of confidence.

"Because there is universal gravitation, two massive planets can attract each other, but I don't think this is the essential reason. Why is there universal gravitation? As far as I know so far, Newton only summarized this phenomenon, and every time If all can be proven successful, then we have the law of gravity, right?"

"Well...actually this problem has not been completely solved yet. However, in quantum force electrodynamics, it is believed that electromagnetic force realizes the interaction of forces by exchanging photons. To be more precise, they should be virtual photons."

"Can not you see……"

Wu Bin nodded with some disappointment... In fact, he didn't like the concept of virtuality very much...

Whether it is imaginary numbers, virtual dimensions, or voids, including the virtual photons we are talking about now, as soon as many academics mention virtuality, it basically means that the topic ends here, and any further discussion will be a discussion that cannot be proven.
