When studying the question of star brightness, students can learn from it that building a model requires 'meal awareness'. ”

"Scientists use models to explain phenomena, and all models are inseparable from parameters, and the reason why stars can be seen depends on the combination of two parameters."

"Therefore, the grasp and adjustment of parameters plays a crucial role in establishing a model."

"Wait...... Wait, slow down, I'm a little dizzy. ”

With Wu Bin's endless talk, Gu Jiaqi was finally defeated, rubbing her temples and thinking about life on the sofa.

"Hahahaha." At this time, Pei Jiamin couldn't hold back, laughed out loud, looked at Gu Jiaqi and said, "Do you think it's still fun to make rolls now?" ”

"Not really!" Gu Jiaqi sat up straight, "I'...... I just need to digest it, and what Brother Wu Bin said is very interesting. ”

"Is there anything you don't understand?" Wu Bin asked with concern.

"No, no." Gu Jiaqi waved her hand, "It's that I can't keep up with the rhythm a little, now it's okay, Brother Wu Bin, you can continue." ”

Wu Bin: "If you don't understand something, feel free to say it, I can explain it to you." ”

"Okay." Gu Jiaqi nodded.

"What are you talking about? In the process of inquiry, children can learn part of the foundation of science, that is, to construct a model and set a parameter. ”

"In this way, in their future studies, such as studying problems such as solar eclipses, they will immediately think that they need to pay attention to the parameters for building a model, and make corrections to the parameters based on the results of observations."

"Do you have a compass here?" Wu Bin suddenly asked Gu Jiaqi.

"Yes! You wait. After Gu Jiaqi finished speaking, she ran into the room.

Taking advantage of Wu Jiaqi's departure, Pei Jiamin looked at Wu Bin and said, "Professor Wu has become an astronomy expert again?" ”

"A little bit of research." Wu Bin smiled and nodded.

Just when Pei Jiamin was about to complain, Gu Jiaqi had already run out with a compass and a piece of paper.

"Give." Gu Jiaqi handed the compass and paper to Wu Bin.

"Thank you." After taking the compass, Wu Bin drew a semicircle on the paper.

"Specifically, it's about fixing the orbital inclination to adjust your model based on the observed results." Saying that, Wu Bin pointed a few positions on the circle, "It is the position relationship between the sun, the earth and the moon." ”

“emmmmmm……”

stared at the circle on the picture and meditated for a long time, and just when Wu Bin thought that she was uncomfortable, Gu Jiaqi suddenly slapped her head and shouted.

"I'm enlightened!"

"Poofha......" Pei Jiamin on the side laughed on the sofa again.

"What are you laughing at, I just understand!" Gu Jiaqi pouted and looked unhappy.

"Tell me, what did you realize?" Wu Bin asked with a smile.

"I know what Brother Wu Bin wants to tell me is that even if you can't instill all the complex knowledge of astronomy in your children, you can teach them the scientific method first, right?"

"That's a very good summary." Wu Bin couldn't help but applaud Gu Jiaqi twice, and looked at Pei Jiamin, who was stunned, and said, "Still laughing, your sister is much better than you." ”

"You're listening." Pei Jiamin was very surprised, "I'm impressed with you." ”

"Actually, I'm a little blind." Gu Jiaqi, who was praised for it, suddenly became modest, but the smile on her face showed that she was very happy.

"Don't be modest, you summed it up correctly, I just told you so much, in fact, this is what it means, teaching should not only be a list of facts, but also the cultivation of scientific methods and scientific vision."

"Well, I think Brother Wu Bin is so powerful, no wonder you taught my sister to Jiaotong University." Gu Jiaqi looked at Wu Bin's eyes full of stars.

"Hey, hey, what's the matter with me all of a sudden?" Pei Jiamin, who suddenly lay down the gun, expressed dissatisfaction.

"Okay, good, don't say it, don't say it." Skipping this topic, Gu Jiaqi asked again: "Then which faction are you, Brother Wu Bin?" Do you support astronomy as a separate course, or do you not? ”

"Me?" Wu Bin thought about it after listening, "How to say it, this is a matter determined by the general environment, if you list a separate astronomy class now, I estimate that the teacher of this course will also be a perennial and frail person." ”

"Huh? What do you mean? Gu Jiaqi, who didn't understand for a while, was a little confused, but quickly reacted, "Oh, you mean that the main teacher will steal the class, right?" ”

"Yes." Wu Bin nodded.

"Why? Astronomy should be a very important class, right? Gu Jiaqi was puzzled.

"Because there are very few people who will engage in astronomy in the future, but there are many places where physics, geography, and mathematics need to be used, in general, the status of astronomy is not much different from that of art and sports, and it can only be regarded as a hobby, and there are even very few universities with astronomy departments in China, which is enough to see."

"Okay......" Gu Jiaqi was a little disappointed after hearing this, "Then which of these universities with astronomy departments is better?" ”

"The University of Science and Technology is not bad, now it is also united with the Purple Mountain Observatory, if you will study in the future, you can theoretically find Zitai researchers as mentors, they can be said to be a group of people at the forefront of domestic research on the stars and seas."

Wu Jiaqi: "Is that Brother Wu Bin's school?" ”

"Yes, if you're really interested, I can tell you about the astronomy department at HKUST."

Wu Jiaqi: "Really!?" That...... Then I'll seriously consider it. ”

"Wait, Jiaqi, you don't really want to take the astronomy exam, do you?" Pei Jiamin looked at Wu Jiaqi's serious expression, and suddenly realized that things seemed to be rushing in a direction she didn't expect at all.

"yes, I'm serious!" Wu Jiaqi nodded.

"I've never heard you have such an ambition...... You can't be hot for three minutes, that's a lifetime event. Pei Jiamin's tone was a little eager.

"Of course I understand the importance, but I've been interested in galaxies since I was a kid, and I know that this kind of thing can't be chosen by interest, but in the next year, I'll try to learn a little more about astronomy."

"Hmm...... I don't want to discourage you, but before diving into astronomy, I think you should first look at the cut-off score for HKUST. ”

"Oh!" Gu Jiaqi's expression suddenly froze, and then slowly looked at Wu Bin, and suddenly remembered that this was the school that the top student in the college entrance examination went to!

"If you count the number of enrollments...... In a sense, it is not simpler than Jingbei. Wu Bin responded to Gu Jiaqi, who was looking at him.

"Sue!"

"Nope! I'll try! ”
