Actually, Lu Zhou didn't really understand Professor Joseph's explanation.
However, he was very familiar with the equations on the whiteboard.
Even though it only took him an hour to complete these equations, it didn't mean that his time was worthless.
"… I don't disagree with your point of view. Every discipline should have its own research ecosystem, and mathematics shouldn't steal the spotlight. But that's not what I want to say." Lu Zhou coughed and pointed at the whiteboard. He then said, "The equation on the third line … isn't used like this."
The moment the words left his mouth, a cold glint flashed across his eyes.
The lecture hall, which was already in an uproar because of his question, became even more lively!
A lot of people looked at the back row. They were curious as to who was so arrogant as to challenge Professor Joseph directly. Joseph was a big name in the economics world, why would he want to offend his supervisor?
"Someone is questioning Professor Joseph's mathematics ability?!"
"Even Professor Krugman didn't say anything …"
"Who is this guy? He looks quite young, probably a student? "
"Wait a second, I feel like … this guy looks familiar, but I can't remember where I saw him before."
"…"
"Please tell me what the problem is," Professor Joseph said. He saw that the person standing up was the one who was playing with his phone during the report. He said, "Or do you think you know how to use these things better than me? That you know more about the Lu Bewley model than me? "
Lu Zhou nodded and said, "If it's just the mathematics part."
The audience went into an uproar.
Professor Joseph frowned. Instead of being angry, he smiled.
"Oh? Then I'm curious, what's your name? Which university are you from? "
When Lu Zhou heard this unrelated question, he couldn't help but feel a headache coming on.
Speaking of which, is my face that hard to recognize?
This is the second time someone has asked me this question.
Even if I'm from a different race, I should still be handsome, right?
After letting out a sigh, he spoke.
"University of Jin Ling, Lu Zhou.
"Or, you can call me Professor Lu."
The lecture hall became strangely quiet after he said this.
Lu, Lu Zhou?!
When this name came out of Lu Zhou's mouth, not only was Joseph shocked, but all of the scholars in the lecture hall were stunned by this sudden turn of events.
They all looked at the young scholar who stood up. Many of the economists in the room cursed in their hearts.
There were also many people who recognized Lu Zhou's face the moment he stood up, but they didn't dare to confirm it.
After all, no one expected Lu Zhou to appear in a macroeconomics forum that had nothing to do with mathematics.
Also, no one had ever heard of this guy appearing at an economics conference before.
This was something that had never happened before. Unless one stared at that face every day, no one would be able to recognize him at a glance!
On the other side, a young lady in her twenties who was sitting in the hall also instantly widened her eyes.
Bro?!
When Xiao Tong heard the familiar voice, she turned around and looked at the person in the back row. Her eyes almost popped out of her head!
Professor Krugman was sitting next to her. He rubbed his hands excitedly and spoke.
"He's here! I told you! He'll come! "
He suddenly remembered something, and he immediately looked at Professor Angus.
Professor Angus suddenly coughed and stood up from his seat. He was about to leave.
"I'm going to the bathroom …"
Professor Krugman smiled.
"It's fine if you go to the bathroom, but don't forget our bet!"
Professor Angus saw that he couldn't escape, so he angrily said, "I know, you stingy bastard … It's just a few gold coins, right? You ate so much chocolate, aren't you afraid of losing all your teeth? "
"Haha, I'm just taking what I deserve … Speaking of which, are you really going to the bathroom now?" Professor Krugman raised his eyebrows in the direction of the whiteboard and said, "He looks like … He's going to write on the whiteboard."
When Professor Angus heard this, he hesitated for a second and sat back in his seat.
"I suddenly feel like I can hold it in for a bit longer …
"Let's see what he's going to write first."
…
Lu Zhou didn't expect that he would end up standing in this place, even though he was just here to watch the show.
After he pointed out the problem with the calculation process on the whiteboard and told the old man his name, Professor Joseph didn't give up. He even gave up the podium and the whiteboard and asked Lu Zhou to point out what was wrong.
Actually, Lu Zhou didn't want to come on stage.
However, as a scholar, when he discovered that someone used his theory incorrectly, as the one who proposed the theory, it was his obligation to point out the mistake and correct it.
After all, no one in this world knew the meaning of the Lu Bewley model better than him.
I want to keep a low profile, but I'm not strong enough …
Lu Zhou sighed in his heart. He picked up the marker, cleared his throat, and spoke casually.
"I'm only going to write it once, watch carefully."
Professor Joseph was expressionless. He stared at the whiteboard with an oppressive gaze.
However, this oppressive gaze didn't give Lu Zhou a lot of pressure.
He stood in front of the whiteboard and thought for around five seconds. The marker in his hand moved like a feather, and in just a few seconds, he had smoothly written a line of equations on the whiteboard.
Time slowly passed by. Professor Joseph looked at the more and more equations on the whiteboard. His pupils suddenly contracted, then slowly enlarged. He couldn't believe what he was seeing, but he was shocked.
He wasn't surprised by Lu Zhou's words.
Even though the large amount of information in the equations was quite surprising …
However, what shocked him even more was that Lu Zhou did not pause at all when he wrote down these equations! He didn't even stop to review the previous steps to think about the next step!
That's right, he didn't even pause for half a minute!
It was as if the entire model had been imprinted in his mind, and he already had a complete blueprint of how to stack each of the building blocks.
A drop of sweat gradually slid down his forehead.
What Joseph couldn't believe the most was that he, who was originally confident in his own process, was actually starting to doubt whether the mistakes he had exposed were really so obvious that he didn't even need to think about them …
When Lu Zhou wrote the last line on the whiteboard, the entire report venue was abnormally quiet.
Obviously, not only did he win over Professor Joseph, but all of the economists sitting there were also completely won over by the equations on the whiteboard.
Compared to Professor Joseph's blackboard writing, Lu Zhou wrote down every step in detail. He accurately circled the problematic steps in Professor Joseph's blackboard and corrected them.
Professor Joseph's shoulders trembled as he looked at the whiteboard in disbelief. He spoke with a trembling voice.
"This is impossible …
"Even if I were to sit in the library and calculate all these things, it would take at least a few hours …"
"How did you do it?!"
Lu Zhou smiled and hung the marker next to the whiteboard.
"Tell me first, right?"
Even though he didn't want to admit it, the result was obvious.
Professor Joseph went silent for a while before he reluctantly nodded.
"I admit … I misunderstood the Lu Bewley model, you're right."
There was a commotion in the lecture hall.
Professor Joseph actually admitted that he was wrong?!
Almost everyone had an expression of disbelief on their faces.
Even after hearing Lu Zhou say his name, a lot of people had a feeling that Professor Joseph would lose. After all, no matter how good he was at mathematics, he wasn't at Professor Nash's level. There was an insurmountable gap between him and a Fields Prize winner.
However, no one expected him to lose so completely. He didn't even have a chance to debate …
"Do you know what you did wrong?"
"I know …"
Even though he had to lower his head to a younger scholar, Joseph felt an indescribable sense of humiliation.
But bowing down to a correct viewpoint …
That wasn't humiliating.
Lu Zhou looked at Professor Joseph, who was nodding like a student.
Not bad.
When he first went on stage, he thought that even if he told this old man what he did wrong, this old man would deny it and argue with him from an economic point of view.
But now, it seemed like Joseph wasn't that kind of person.
Being realistic was a virtue.
Especially for scholars.
"Then I'll leave the correction to you. I don't know much about this stuff." Lu Zhou didn't want to embarrass him anymore. He turned around and walked toward the lecture hall entrance.
Professor Joseph saw that Lu Zhou was about to leave, so he quickly stepped forward and tried to stop him.
"Wait a second, you haven't told me how you were able to —"
"Oh, I see … It's not that hard."
Lu Zhou stopped walking and looked back at Professor Joseph. He smiled awkwardly and spoke.
He smiled and said, "Not to mention, I only spent an hour making the Lu Bewley model."
"It shouldn't take that long to correct a mistake, right?"
