Chapter 89: Chapter 75 Boring Professors (First add one more update for monthly pass!)_2
Especially that line, "I guess your Chinese scores were never any good," almost caused Qian Yuhai to suffer an internal injury.
He really almost laughed out loud.
But this clearly wasn\'t the right occasion, so he had to hold it in.
What he didn\'t expect was, Qiao Ze suddenly looked at him and added, "I\'ve seen Professor Qian."
Qian Yuhai asked in surprise, "Oh? You\'ve seen me? When?"
"I\'ve watched your \'Group Theory\' series of open course videos on the internet," Qiao Ze replied.
Qian Yuhai suddenly realized...
Those were a series of videos that a student had asked permission to record and edit during his lectures years ago, and they had been posted online.
However, such videos involving professional knowledge didn\'t attract many viewers.
Qian Yuhai hadn\'t paid much attention to them and had even nearly forgotten about it.
So he explained, "That wasn\'t really an open course, just a small classroom thing, something a student put together on a whim. How so? Did it help you?"
Qiao Ze nodded and said, "Yes, it did. However, when you were discussing the linear representation of infinite groups, there was a problem in your analysis of locally compact topological groups that troubled me for quite some time."
"Oh?! There\'s something like that? What\'s the problem?" Qian Yuhai was startled by this, and his urge to laugh flew away.
"When talking about the group delta and the exponential map, part of the content involved deriving delta from the Banach algebra itself via the exponential map. There\'s a small mistake in the proof that delta is within the connected component containing y—the function example used overflows.
Luckily, the final conclusion is still correct because it\'s only missing a restriction condition," Qiao Ze detailed the specific issue seriously.
"That content should be from the textbook. Could there be a possibility that you have misunderstood?" Qian Yuhai couldn\'t help but say.
Qiao Ze shook his head and then pulled out his phone, starting to fiddle with it.
The atmosphere around the table began to shift again.
Qian Yuhai suddenly felt a bit uneasy.
Could it be?
Could there really be a problem with the example in his proof?
"Um... Qiao Ze, why don\'t we eat first? Such a small issue, we don\'t need to take it so seriously," Xu Dajiang was the first to speak up.
Qiao Ze looked up seriously and said, "But in mathematics, there is no small issue; the line between right and wrong is very clear."
Almost at the same moment, Qian Yuhai also said, "I\'m quite curious to know where the mistake is, after all, we must not mislead the young, right?"
Well, Xu Dajiang didn\'t feel like talking anymore.
Whatever.
Luckily, it didn\'t take long for Qiao Ze to find the right part of the video, as he pulled the progress bar to the correct spot and then handed over the phone directly.
"You can look at what is being written on the blackboard and think about it again. What would happen if we don\'t impose restrictions on the Kronecker function?"
Qian Yuhai took the phone, frowning as he carefully watched the content from his lectures years ago, while his mind quickly processed what Qiao Ze hinted, then after a moment, it clicked—a restriction condition was indeed needed. He said reflexively, "Shouldn\'t take the interval from 1 to -1, right?"
"That\'s right," Qiao Ze nodded.
The table suddenly grew quiet again.
Ma Wanxiang suddenly felt that it was good for everyone that Qiao Ze didn\'t attend classes, avoiding any potential mutual harm.
After all, if he pointed out a mistake so directly during a lecture, it would indeed affect the lecturer\'s mindset.
"Haha, Group Theory, to explain it clearly would take dozens of lectures at least. Such small errors are inevitable, and even could be said to be of high quality. Haha, it must have been that Professor Qian forgot to include it when he was lecturing," Xu Dajiang tried to smooth things over again. Your next journey awaits at m v|l-e\'-NovelBin.net
After all, this was happening at Xilin University of Technology\'s home turf; as the host, he couldn\'t allow the atmosphere to become too awkward.
However, Qiao Ze still seriously responded, "I haven\'t watched the whole series. I used Professor Qian\'s course as a supplement. Even though there are over a hundred episodes in total, I\'ve only watched twenty-six of them. Many parts I just skipped over."
"Um..."
Xu Dajiang was a bit stunned, not quite sure what to say next, but luckily the emotionally conflicted Ma Wanxiang quickly recovered and hastily instructed, "Waiter comrade, our group has arrived. We can start serving the food now. Let\'s eat first, eat first. After all, I\'m getting hungry."
"Yes, let\'s eat first, everybody, haha..."
...
The college naturally would not be stingy when entertaining distinguished guests.
The dishes were plentiful, but most people at the table ate without any relish, the conversation lacking vigor.
Xu Dajiang finally understood why Qiao Ze had ended up at Xilin University of Technology.
Perhaps this kid only acted normal when Li Jiangao was around?
Just going out to eat a few more times could offend everyone completely.
Of course, this time it was clearly a good thing.
Xu Dajiang indeed quite liked the personality the child had shown.
However, he had made up his mind never to show off his academic level in front of this child.
As much as he liked Qiao Ze, he didn\'t really want the boy to critique his papers, did he?
Fortunately, his previous research focus had been on partial differential equations.
A young person who had already been attracted by noncommutative geometry and group theory probably wouldn\'t be so interested in the field of PDE.
That was just fine.
Xu Dajiang also noticed that after Qiao Ze had pointed out the mistake in Qian Yuhai\'s video online, the three professors had exchanged several glances.
But it was not a big problem.
Xu Dajiang felt that with Qiao Ze\'s character, he could probably reduce these professors\' eagerness to poach him quite a bit.
Moreover, he had realized that Qiao Ze truly had no interest in going to Yanbei University. That was essential; as long as Qiao Ze wasn\'t interested, and his enrollment had already transferred over, no matter how much these people wanted to poach him, they could only watch helplessly.
So he really didn\'t mind Qiao Ze showing off a bit more.
To make those people envious to death.
Unfortunately, after pointing out Qian Yuhai\'s mistake, Qiao Ze seemed to have lost the desire to talk anymore.
Especially during the meal, he was extremely quiet.
It was as if he hadn\'t heard the professors\' conversation amidst the clinking glasses, just silently eating his meal.
After finishing two bowls of rice, Qiao Ze put down his chopsticks and said, "I\'m full."
"Ah?!" Xu Dajiang was somewhat slow to react.
However, Zhang Hongcai, who had been paying attention to Qiao Ze across the table, said with mild surprise, "Huh... that\'s it? You\'re full? How about, after the meal, we have a cup of tea here and just chat for a bit?"
Qiao Ze shook his head and said, "No more talking, I\'ve been really busy recently, I need to go back to my dorm."
Zhang Hongcai felt it would be imprudent to keep Qiao Ze any longer, especially since he had just been criticized by the youngster for his poor understanding of language... in other words, for not comprehending human speech.
Xu Dajiang then came to his senses and understood — this kid truly came just to eat, so now that he was full, it was entirely reasonable for him to want to leave.
At the same time, Xu Dajiang also made a resolution.
For any future socializing activities that involved interacting with people, he absolutely would not include Qiao Ze.
Of course, if someone really wanted to be masochistic, before coming for the meal, he would have to inform the school security department, best to arrange a few security personnel to follow him...
"Well... in that case, Qiao Ze, look, Professor Zhang and the others haven\'t finished eating yet, we can\'t leave right away. We\'re not at the university, and I\'m not comfortable with you going back alone. So, just sit for a while, I\'ll make a phone call and ask your counselor to pick you up, you wait here for him for a bit, how\'s that?" Xu Dajiang quickly suggested.
Qiao Ze nodded.
Liu Hao had a car, and all things considered, waiting a while to drive back would actually take about the same time as walking back himself; historical experience showed that the counselors responded quickly to calls from this dean uncle.
Although this Dean Xu might be somewhat boring and free, Uncle Li had said to give this uncle some respect, even if his concerns were a bit trivial.
"Well, since that\'s the case, Qiao Ze, it\'s good that you\'ll stay a while longer. I have a question about noncommutative geometry I\'d like to discuss with you..."
Zhang Hongcai had just started speaking when Qiao Ze shook his head and said, "Professor Zhang, that day when Dean Xu mentioned you to Uncle Li, I flipped through your papers in Uncle Li\'s office. Your research involves commentary on noncommutative geometry through noncommutative quotient spaces, which is fairly in-depth theoretical mathematical research.
I study noncommutative geometry just to facilitate understanding C* algebras and algebraic quantum field theory. Because I\'m only very interested in quantum physics, noncommutative geometry helps me understand the quantum world, but I don\'t intend to delve into this direction, so there\'s nothing to discuss."
Oh...
Quantum physics?!
