Listen to Sister Minmin, you are the one with the best grades in her high school, right? ”

Not long after eating, Gu Jiaqi, who had taken a sip of chicken soup, suddenly looked at Wu Bin and asked.

Wu Bin listened to the chopsticks that pinched the fried garlic sprouts, then nodded and said, "Well, she didn't lie to you." ”

"Wow! It's amazing. Gu Jiaqi looked adoring.

"What's more." At this time, Lu Miaomei also opened her mouth to take over the topic, "He was the champion of the Huhai College Entrance Examination that year." ”

"Huh!!" Gu Jiaqi let out a cry of surprise and looked at Pei Jiamin: "Sister, why didn't you tell me this." ”

"You didn't ask." Pei Jiamin gave her a blank look.

"Wow! Aren't you a super student! You wait for me. After Gu Jiaqi finished speaking, she suddenly jumped off the table and ran back to Pei Jiamin's room.

Looking at the happy cousin, Pei Jiamin couldn't help but hold his forehead and said, "Wu Bin, let me tell you first, my cousin likes her own brain supplement very much, so don't you believe everything she says?" ”

"Okay, I see." Wu Bin nodded and continued to eat.

After a while, Gu Jiaqi ran to Wu Bin with a pen and a math book, handed the book and pen to Wu Bin and said, "Please sign for me." ”

"Signature ......?"

Wu Bin, who asked for questions, asked for notes, and asked for learning methods, had all seen them.

'This is the first time this has been signed......

"That's right, autograph, let me rub some of the power of the scholar, please, please." Gu Jiaqi clasped her hands together and said seriously.

"Okay...... Wu Bin smiled and took the book and pen, "Sign on the title page?" ”

"Nope! Please sign on the cover. Saying that, Gu Jiaqi pointed to the center of the book, "That's it." ”

"Okay." Wu Bin nodded, signed his name on the book and handed it back to Gu Jiaqi.

"Thank you." happily took the book, Gu Jiaqi looked at the two words Wu Bin on it and said: "Xueba is Xueba, the words are really beautiful." ”

"Thanks for the compliment."

After signing the name, Gu Jiaqi seemed to have a lot of relationship with Wu Bin at once, and the conversation started at once.

"Did you really start accumulating until your third year of high school?"

"Is that physics contest difficult? Is it too late if I want to participate now? ”

"Huh? You didn't even go to Jingbei!? ”

"Oh...... What kind of university is HKUST? ”

……

Until the end, Lu Miaomei coughed lightly and said, "Jiaqi, when you eat, just eat well first, and then ask after eating." ”

"Oh......" Gu Jiaqi stuck out her tongue after hearing this, and buried her head in eating.

"I'm sorry, this kid was a little too excited." Lu Miaomei looked at Wu Bin and said.

Wu Bin waved his hand and said, "It's okay, I'm happy to answer my academic questions." ”

"Xuebada is really close to the people!" Gu Jiaqi gave Wu Bin a thumbs up.

After that, Gu Jiaqi was also very obedient, and she didn't keep asking during the meal, but as soon as Wu Bin finished eating, she pestered her again.

"It's time for you to make the papers!" Pei Jiamin pulled Gu Jiaqi and said.

"Wait a minute, I'll go after I finish asking this question." Gu Jiaqi was on the sofa and had no intention of leaving.

Sighing, Pei Jiamin had no choice but to sit aside.

"Hehe, sister, you're the most enlightened." After making a heart-to-heart gesture to Pei Jiamin, Gu Jiaqi continued to ask Wu Bin: "Actually, I have a very serious question I want to ask." ”

"Well, just ask." Wu Bin smiled and nodded.

"Why is there no astronomy subject from elementary school to high school?"

After listening to Gu Jiaqi's question, Wu Bin couldn't help but be a little surprised, he didn't expect that it was really a question of a bit deep.

"Are you interested in astronomy?" Wu Bin asked.

"Hmm!" Gu Jiaqi nodded, "I like to look at the stars!" ”

"This question is really a bit long." Wu Bin touched his chin and really didn't know which point to start talking about.

"It's okay, just say it slowly." Gu Jiaqi's eyes lit up.

"So you don't have to make rolls, right?" Pei Jiamin immediately debunked Gu Jiaqi's careful thoughts.

"Not really!" Gu Jiaqi pursed her lips, "I'm really curious!" Sister, you said that there are no astronomy classes in elementary school, junior high school, and high school, so who would choose the astronomy department when they go to college? ”

Hearing Gu Jiaqi's words, Wu Bin thought for a while and said: "Actually, astronomy does not appear in middle and high school textbooks, but they are all scattered and hidden in various subjects. ”

"Uh-huh, like?" Gu Jiaqi looked expectant.

"For example, starting from Kepler, astronomy bid farewell to mathematical geometric models and began to move closer to physics, and it can be said that after Kepler's three laws as the basis, many theoretical formulas in astronomy can be classified into physics."

"Oh yes, and the principle of astronomical telescopes is actually optics, which naturally will also appear in physics textbooks."

"Oh~" Gu Jiaqi nodded, "What else?" ”

"Mathematics, from primary school textbooks actually teach you the concept of the calendar and the corresponding conversion, of course, only a small part, such as hours, minutes, seconds, as well as the calculation of dates and leap years, etc."

"Is this astronomy?" Gu Jiaqi was a little surprised.

"Of course, they're the most basic part of astronomy." Wu Bin smiled and nodded.
