Chapter 18 I can do it (please vote for me)
Qiao Yu’s indifferent attitude almost made Lan Jie get stuck.
You were so resistant yesterday, but are you able to get whatever you want today? How could this child's mentality change so quickly?
Well, I can only say that this little guy is really serious about making money.
"Okay, as long as you are willing to quit smoking. The school Olympiad training class is held every Monday, Wednesday and Friday from 4:00 to 5:30 pm. For the next month, you will not need the third afternoon class. Come on, just go to the 302 electronic classroom in this building before four o'clock. We will notify you of the holiday training class.”
After calming down, Lan Jie began to explain in earnest.
Qiao Yu nodded, and then asked proactively: "Just three classes a week? What books should I read on a daily basis? I only have one "Introduction to Riemannian Geometry" at home."
"Riemannian geometry? What are you looking at that thing for?" Lan Jie was stunned and asked.
"Wouldn't self-study be helpful for the competition?" Qiao Yu asked rhetorically.
Ran Jie swallowed, then shook his head decisively and emphasized: "No, there is no help at all."
"Oh, that's good." Qiao Yu also breathed a sigh of relief, which showed that the Olympiad questions seemed really simple.
"Can you understand that book?" Lan Jie couldn't help but ask.
To be honest, Lang Jie did come into contact with the content of Riemannian geometry when he was studying for a master's degree, but he only had a general understanding of it. After all, what he learned did not require a very in-depth understanding of these things.
“I don’t fully understand.” Qiao Yu shook his head honestly and said, “The previous discussion on manifolds and tangent spaces was okay, but when it comes to the Riemannian metric, connection and curvature, it’s just It feels a bit difficult."
"Have you ever taught yourself calculus, linear algebra and topology?" Lan Jie was surprised. This was something he had not mastered.
If you want to understand the basics of Riemannian geometric manifolds, you must study these subjects systematically. Otherwise, it is impossible to understand concepts such as smooth manifolds, tangent spaces, vector fields, etc.
Similarly, if you have not been exposed to linear algebra and topology, it is impossible to understand concepts such as vector space, linear mapping, basis, coordinate system, open set, closed set, continuous mapping, etc.
If you don’t understand these, you can’t understand the structure of the manifold in the book.
Qiao Yu nodded: "I have watched a lot of class videos scattered on the Internet. I also borrowed a few books from the library and read them."
Lan Jie shook his head. Shaking his head, he said seriously: "The content of the Mathematics Olympiad Geometry exam is mainly plane geometry, solid geometry, involving Euclidean geometry and trigonometric geometry. In fact, all Olympiad questions will not include college mathematics content. But now you This situation..."
Having said this, Lang Jie hesitated for a moment, then bent down and opened the cabinet under the desk. In a moment, he pulled out three books and handed them over.
“If you have a lot of spare time and want to study advanced mathematics, you can systematically read these three books first. If you don’t understand anything, you can ask me.”
Qiao Yu Conglan Jie took the book in his hand and read the title carefully.
One is "Principles of Mathematical Analysis Volume 1", the author is Feichingolz, the second is also "Principles of Mathematical Analysis", but the author is Ludin, and the other is "Algebra" The author's surname is Feng Keqin.
Then Qiao Yu handed back "Principles of Mathematical Analysis Volume 1" by Feihejin Goerz: "Thank you, Mr. Lan, but I won't use this one. I don't like his book on mathematical analysis." Taught myself.”
"Have you studied by yourself?" Lan Jie was a little surprised, but he didn't say much. He took the book back and said, "Then you might want to read Ludin's book. There are some ways in which the two books can complement each other."
"Okay, Teacher Lan."
Lan Jie curled his lips, suddenly thought of something, and said: "By the way, I'm not sure about your advanced mathematics mastery. You can go Learn about the global mathematics competition organized by Little Libaba
“The exam award is 30,000 U.S. dollars. Isn’t that a bonus of more than 200,000 RMB? Is there a fee to convert it into RMB? "Qiao Yu asked three consecutive questions in an instant.
Lan Jie was startled for a moment, and then saw the twinkling light in Qiao Yu's eyes.
Really, he just said it casually. After all, the topic has already been discussed here. I just didn't expect this guy to be so sensitive to bonus numbers. Especially when people focus on whether they can participate in the competition, this guy is actually thinking about whether he has to pay taxes...
"Of course you have to pay taxes on bonuses. But you don't have any other income. If you really get the bonus, you will have to pay taxes next year." You should be able to apply for a tax refund every month. As for the US dollars, it is because this is a global competition, and there is probably no handling fee when converting to RMB." Lan Jie explained.
I didn’t pay too much attention to it, because he had never won an award, so I really didn’t know.
"More than two hundred thousand." Qiao Yu sighed.
It would be great if he could win a gold medal. With this money, his family assets would instantly increase by 200%. At least he can participate in the game with confidence.
Lan Jie glanced at Qiao Yu warily and warned: "Do you understand the meaning of the global mathematics competition? You are not competing with your peers. There are universities in China such as Huaqing and Yanbei. masters and doctoral students, as well as top students from foreign universities such as Cambridge and Harvard.
Although you can register to participate in the preliminary round, and the competition is online, there are strict proctoring measures for entering the finals, so you must not think of cheating, even if you win the prize. It’s useless.”
Don’t blame Lan Jie for being worried.
He could feel Qiao Yu's persistence in making money.
That's all. The key is that this kid still has an evil spirit.
Lan Jie has no doubt that if Qiao Yuzhen finds a way to cheat, he will definitely do it for the bonus without hesitation.
"Don't worry, Teacher Lan, I know it well. To be honest, I have never cheated on an exam since I was a child." Qiao Yu answered.
To be honest, Lan Jie is still not reassured. He believed that Qiao Yu had never cheated on exams since she was a child, at least in junior high school. After all, there was not much room for improvement in her performance. But after all, there are no bonuses for those exams.
I still wanted to say something, but thinking that Qiao Yu was only a fifteen-year-old child, at the age of rebelliousness, I still refrained from saying anything.
It arouses a rebellious mentality, and it would be bad if it causes something trouble. So Lan Jie simply changed the topic to the high school entrance examination: "I heard from your teacher Yuan, do you plan to take the high school entrance examination normally?"
Qiao Yu nodded and responded: "Yes."
"Are you confident?" Lan Jie asked.
“I think it’s okay to at least cross the General High Line.” Qiao Yu said conservatively.
Lan Jie nodded noncommittally, and then said calmly: "Qiao Yu, you have talent. As long as you are willing to show it, I believe that no matter where you go in the future, you will be discovered. But I still hope that you can stay in Tieyi
This is not only for your consideration, but I also have selfish motives. But one thing is that only in Tie Yizhong can I guarantee that all the promises I made to you will be fulfilled. To be honest, in your case. Personally I think I’m participating this year The exam is still risky. Are you sure you must take the high school entrance exam this year?”
Qiao Yu raised his head and smiled confidently, and said, “Okay, I will take the mock exam seriously next time. If you add If the previous scores in physical education and raw materials are not 620, I will follow your arrangement."
Lan Jie hesitated for a moment and said, "That's OK."
"Then I'll leave first?"
"Well, don't forget classroom 302 at 4 o'clock tomorrow afternoon."
"Okay, goodbye, teacher."
"Wait, add WeChat."
" Uh, I'm sorry, Teacher Lan, I didn't bring my mobile phone today."
At this moment, Qiao Yu thought of Xia Keke, look, it's all the little girl's bad deeds.
"Ah?" Lan Jie glanced at Qiao Yu: "Okay, 13XXXXXXXX, write down my phone number and add me when you get home."
"Hey, wait, don't leave in a hurry. Please also leave me a phone number.”
