The top student must be diligent.

Chapter 21: Examination of Academicians
"Hello, can you hear me? Xiao Yi?"

"I can hear you, Professor Liu."

Xiao Yi faced the computer and responded with a confused look on his face.

Just five minutes ago, he was reading "Principles of Number Theory" in Chinese class, and then he was called into Luo Penghua's office.

and……

He was also approved to use Luo Penghua's mobile phone.

Then he learned that Professor Liu, who was attending a mathematics academic conference in Beijing, wanted to see him about something very important.

And, video calls are also needed.

So now, he saw Liu Bin on the mobile phone screen.

It looks like Liu Bin is at some banquet?
Liu Bin smiled and said, "Xiao Yi, how are your studies going recently? Have you read the book I brought you?"

"Of course I did!" Xiao Yi nodded and said gratefully, "I've never come across such data before. Now that I've come across it, I realize that mathematics can be so interesting!"

Liu Bin immediately laughed and asked, "Is it the book Mathematical Analysis? It's a very good thing that you are interested in this book. When the freshmen in our college first learned this book, almost 99% of them looked miserable."

"Uh..." Xiao Yi hesitated for a moment, not knowing what to say.

Liu Bin noticed his hesitation and asked, "What's wrong?"

"Well... actually it's not just Mathematical Analysis."

Xiao Yi said: "In the past few days, I have finished reading "Mathematical Analysis", "Advanced Algebra", "Analytical Geometry", ..., "Elementary Number Theory", and now I am studying "Principles of Number Theory". The knowledge in these books is quite interesting to me."

"Especially this book, Principles of Number Theory. The problems raised in it and the methods to solve them are very interesting to me."

Liu Bin on the other side of the video fell silent.

If he heard correctly, Xiao Yi had finished reading 7 books in these four days and had already started reading the 8th book.

Even... the book "Principles of Number Theory".

He remembered that the "Principles of Mathematics" he gave Xiao Yi was a relatively difficult number theory book, mainly for those advanced number theory scholars. But now Xiao Yi has started reading this book?

Of course, no matter what book Xiao Yi reads, it doesn't matter. The most important question is, "How did you manage to read the eighth book in less than four days?!"

Liu Bin finally asked out loud in disbelief.
"Read two books a day, and then you can read the eighth book today." Xiao Yi replied.

What the hell...

Liu Bin didn't know what to say.

Because he really didn't know how to refute what Xiao Yi said. Two times four equals eight, who doesn't know that?
After a long silence, he finally asked another question: "You read two math books a day. Do you understand the contents of the books?"

"That's not true."

Xiao Yi's answer finally made Liu Bin feel relieved. That is to say, if you read two books a day, how can you understand all the knowledge in the books? This is what a normal person does!

Then he would become serious and criticize Xiao Yi's habit of "not seeking to understand deeply". How could one read a math book with such an attitude?
However, before he could open his mouth, Xiao Yi's next sentence came: "Basically, I only understood about 80%."

"Analytic geometry is okay. The content of that book is relatively simple. I probably mastered about 95% of it after reading it once. The most difficult part is real variable function theory. That book is not only thick, but also very difficult. It is much more difficult than the other book complex variable function theory. So it took me almost a whole day to finish reading this book, and I probably only mastered less than 70% of the content."

“But this book is really interesting.”

"Then there is the book Principles of Number Theory that I am reading now. The Fermat's Last Theorem described in it is really amazing. Mr. Andrew Wiles, who proved Fermat's Last Theorem, is also really admirable!" "..."

Liu Bin became even more silent.

Of course, while he remained silent, the professors around him also showed expressions of disbelief.

What did they hear?
I read eight books in four days, including Real Analysis, a book that is the most difficult for lower-grade math students.

Studying real analysis ten times is considered a cliché in mathematics majors. Then this student, who just started his sophomore year this year, said that not only did he finish reading it in just one day, he even understood 70% of it?

Several professors recalled their experience studying real analysis when they were undergraduates.

The reason they were able to become mathematics professors was naturally because they were quite talented in mathematics, but they also had to admit that real analysis was really difficult to learn.

The result... Damn, this young man!

"Hahaha!"

At this moment, a hearty laughter came from beside them.

The person laughing is Hu Guangde.

Now, he really developed a strong interest in this student named Xiao Yi.

If it was just because of Liu Bin at the beginning, then now it was completely because of the feeling that Xiao Yi in the video gave him in these few short minutes.

If what this student said was true, then perhaps he really had met a genius who could create waves in the mathematics world?

Academician Hu's laughter brought Liu Bin back to his senses. He then coughed twice and said, "Okay, Xiao Yi, let's not talk about these things for now. I'll introduce them to you."

He moved his phone to allow Hu Guangde to enter the camera, and said, "This is Academician Hu Guangde of our University of Science and Technology, and also an academician of our School of Mathematics. Academician Hu is very interested in you."

Xiao Yi was immediately shocked.

What?
academician?

He actually met an academician?
Beside Xiao Yi, Luo Penghua also widened his eyes.

Just now Liu Bin told him that he had something great to ask Xiao Yi, and it turned out that there was an academician there!

Wow, if he was favored by an academician before entering university, Luo Penghua couldn’t even imagine Xiao Yi’s future.

"Young man, your name is Xiao Yi, right?" At this time, Hu Guangde spoke first.

Xiao Yi nodded quickly: "Hello, Academician Hu, I am Xiao Yi."

"Don't be nervous. Just think of me as a math teacher at a university." Hu Guangde smiled and said, "You just said that you finished reading so many books in just a few days. Let me test you."

Soon, Hu Guangde sent a word document.

The title is "Convergence of Riemann Integral and Lebesgue Integrability", and there is also an author's name, Zeng Ang.

Obviously, this is a thesis.

"This paper is less than 6 pages long, so it shouldn't take you much time. Take a look at it and tell us what you think of it."
