Xueba's Sea of ​​Stars

Chapter 261 This is also astronomy
"I heard from Sister Minmin that you are the one with the best grades in her high school, aren't you?"

Not a while after eating, Gu Jiaqi, who took a sip of chicken soup, suddenly looked at Wu Bin and asked a question.

After hearing this, Wu Bin gave a pause to the chopsticks pinching the fried garlic sprouts, then nodded and said, "Well, she didn't lie to you."

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

"More than that." Lu Miaomei also took up the topic at this time, "He was the top scorer in the Shanghai College Entrance Examination that year."

"Hey!!" 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! Then you are not a super academic! Just 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 cheerful cousin, Pei Jiamin couldn't help but support her forehead and said, "Wu Bin, let me tell you first, my cousin likes to make up her own brain, so don't believe everything she says."

"Okay, I see." Wu Bin nodded and continued eating.

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

"sign……?"

Wu Bin has seen everyone asking questions, asking for notes, and asking for study methods.

"This is really the first time I want to sign..."

"Yes, sign, let me use some of my power as a school bully, please please." Gu Jiaqi clasped her hands together and said seriously.

"Okay..." Wu Bin took the book and pen with a smile, "Sign it on the title page?"

"No! Please sign it on the cover." 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, sir!" Taking the book happily, Gu Jiaqi looked at the word Wu Bin on it and said, "Xueba is Xueba, the characters are so beautiful."

Wu Bin: "Thank you for the compliment."

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

"Did you really start to accumulate knowledge in the third year of high school?"

"Is that physics competition difficult? If I want to participate now, is there still time?"

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

"Oh... what kind of university is HKUST?"

……

Until the end, Lu Miaomei coughed lightly and said, "Jiaqi, when it's time to eat, you should eat well first, and then you can ask after eating."

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

"Sorry, this kid is 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 any academic questions."

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

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

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

"Wait a little longer, I'll go after I finish asking this question." Gu Jiaqi lay on the sofa and had no intention of leaving at all.

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

"Hey, sister, you are the most open-minded." After making a heart-to-heart gesture to Pei Jiamin, Gu Jiaqi continued to ask Wu Bin: "Actually, I have a very serious question to ask."

"Well, ask." Wu Bin nodded with a smile.

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

After hearing Gu Jiaqi's question, Wu Bin couldn't help but be a little surprised. He didn't expect that she actually asked a somewhat in-depth question.

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

"Yeah!" Gu Jiaqi nodded, "I really like watching the stars!"

"This question is really a long story." Wu Bin rubbed his chin and really didn't know where to start.

"It's okay, just talk slowly." Gu Jiaqi said with bright eyes.

"This way you don't have to do the papers, right?" Pei Jiamin immediately exposed Gu Jiaqi's small thoughts.

"No!" Gu Jiaqi pouted, "I'm really curious! Sister, you said that there is no astronomy class in elementary school, junior high school, and high school, so who would choose the astronomy department when they are in college?"

Hearing Gu Jiaqi's words, Wu Bin thought for a while and said, "Actually, it's not that astronomy doesn't appear in junior and senior high school textbooks, it's just that they have been broken up and hidden in various subjects."

"Hmm, what about?" Gu Jiaqi looked expectant.

"For example, since Kepler, astronomy has bid farewell to the geometric model in mathematics and has begun to move closer to physics. It can be said that with Kepler's three laws as the basis, many theoretical formulas in astronomy can be classified into physics. .”

"Oh, by the way, and the principle of astronomical telescopes is actually optics, so it will naturally appear in physics textbooks."

"Oh~" Gu Jiaqi nodded, "What else?"

"Mathematics, since elementary school textbooks actually teach you the concept of the calendar and the corresponding conversions, of course it is only a small part, such as hours, minutes, seconds, and calculating dates and leap years, etc."

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

"Of course, they are the most basic part of astronomy." Wu Bin nodded with a smile.
