Yan Fuguang glanced at it, and the leave slip was full of crumpled marks, which showed how angry the old man was when he knew.

Knowing the old man's temperament, Yan Fuguang is not in a hurry.

I found a chair and sat down, ready to move with emotion and reason.

"Teacher Qian, I won't delay my study progress if I ask for leave, you should know this, why don't you take a bigger paper for me to do?"

When he heard this, Qian Mingli became even more angry.

"Are you relying on yourself to be a little smarter than others, and you're ready to let yourself go? Mathematics is a thing that is to study more while your brain is working, and when you get older, it's useless to work hard. ”

The old man was bent on leading this genius student to the academic path, and what he said was all heartfelt.

The little girl's family is uncertain, how interesting it is to swim in the ocean of mathematics, what kind of star to be!

Yan Fuguang knew that the old man cherished his talents, but she couldn't directly say that she didn't need to learn this.

Before she could think of a reason, the old man took a sip of tea and began to output again.

"And let me take the papers for you to make, even if you have all the papers in your senior year, what if you have this requirement for yourself? Your goal should be the Goldbach conjecture, not a small undergraduate paper! ”

Qian Mingli dutifully persuaded him, he really didn't want to watch a genius student waste his talent.

However, Yan Fuguang had already been distracted by the words he had just heard.

If this Goldbach conjecture is solved, the old man must have nothing to say, right?

In the blind spot of the field of vision blocked by the desktop, Yan Fuguang took out his mobile phone and typed blindly to find out the so-called Goldbach conjecture.

This puzzle that has plagued the mathematical community for more than 200 years has only one very simple sentence - any integer greater than 2 can be written as the sum of three prime numbers.

Yan Fuguang entered a state of thought almost instantly.

Qian Mingli said and found that there was no response, and when he looked again, Yan Fuguang was in a daze?

Bang!

The old man slapped the table, and it was a heartache.

"What are you doing, what I say is all the wind in your ears?!"

Pressing the pause button on the rapidly scrolling draft in his mind, Yan Fuguang returned to reality.

"I'm figuring out the Goldbach conjecture."

Qian Mingli's mouth opened into an O-shape, he was stunned for a few seconds, and just wanted to speak but was choked by his own saliva.

"Ahem, ahem...... Ahem...... You repeat?! ”

Yan Fuguang repeated with a calm face: "You just said that my goal should be the Goldbach conjecture, so I'm trying." ”

"Yan Fuguang, do you think I'm too old to scold people, ah? Goldbach conjecture, can you solve my conjecture first?! ”

Qian Mingli is not angry, why didn't he find out that Yan Fuguang still had the attributes of being naughty and angry in the past, but now he is so bold that he ridicules the head of the department!

From the perspective of ordinary people, this is indeed more joke than a joke, Yan Fuguang swept around, and saw a pile of white paper in the printer, so he took it directly.

It is impossible to solve the puzzle of the century in such a short time, and Yan Fuguang is ready to talk about his thoughts first.

Qian Mingli didn't know what this girl was going to do at first, but she brushed and wrote and talked.

Gradually, Qian Mingli completely forgot why he was angry, and followed Yan Fuguang's train of thought step by step.

I don't know how long it took, but Yan Fuguang didn't stop writing until the manuscript paper was full of five sheets.

"Time is too short, only so much for the time being."

Yan Fuguang closed the cap of his pen and sat up straight, his expression the same as when he first came, with little change.

Qian Mingli grabbed a few pieces of manuscript paper in front of him with a hand speed that was completely out of age, as if he was holding a rare treasure, and the more he looked at it, the more immersed he became.

Seeing that the old man didn't speak, Yan Fuguang also relaxed and leaned back in his chair, continuing to think about what he had just interrupted.

The clock on the wall turned and turned, but no one cared, both of them were immersed in their own world, and the information from the outside world was completely blocked.

It wasn't until there was a cooing sound in the room that Yan Fuguang came back to his senses.

The wall clock clearly shows 2:40, has it been so long?

Seeing that the old man, who was nearly seventy years old, was still unconscious, and he couldn't even feel hungry, Yan Fuguang had to wake him up.

"Huh? Who, don't bother me! ”

Qian Mingli roared angrily with the impatience after being disturbed.

Yan Fuguang had no choice but to take away the pen and paper in his hand, raise his voice and say, "Teacher Qian, it's not early, it's time for you to have lunch." ”

Qian Mingli, who finally came back to his senses, rubbed his swollen eyes, and also looked up at the time.

"What, it's so late?"

As soon as he spoke, he saw Yan Fuguang holding those treasures in his hand, and snatched them over, and his eyes were completely different when he looked at Yan Fuguang again.

"Don't you tell me you just came up with it in a matter of minutes?"

Qian Mingli's research direction is not number theory, and Yan Fuguang has only made a beginning, and has not gone into depth.

But his instincts told him that at least there was not much of a problem with what Yan Fuguang was expressing so far.

He couldn't believe that a freshman who had just entered college had already studied Goldbach's conjecture?

Qian Mingli now has no time to wonder whether Yan Fuguang can really solve this problem, but even if she can only solve 10%, or even 5%, to prove a conjecture that is weaker than a "weak conjecture", it is also a top-level mathematician-level existence.

If all of these are Yan Fuguang's own thoughts, then the young girl in front of him may be far more genius than a genius.

Although Yan Fuguang did not solve the so-called Goldbach conjecture in her memory, the mathematical tools at her disposal were far from what people of this era could imagine.

I also listened to Qian Mingli's words just now, and I was curious to do it, but now that I think about it, I still have to restrain it.

After all, the old man couldn't go too far with the promise.

So, Yan Fuguang shook his head.

"I've thought about this before, and what I just said is the result of a summary."

only denied the time, but did not deny the source of the ideas, so these were really Yan Fuguang's own ideas?

Qian Mingli only felt that he had suffered the greatest mental impact so far.

He studied under Fields Medal winner Wolf Lelen and completed his PhD at MIT, whether it was a teacher, a teacher, a teacher, or a colleague and student over the years, he met many people who can be called mathematical geniuses.

But the world of mathematics couldn't be more cruel.

Mathematics requires talent, accumulation, and occasional flashes of inspiration, and it is not an exaggeration to say that mathematics is the discipline with the most disproportionate effort and reward in the world.

It's not that geniuses succeed easily, and many mathematicians may live ascetic lives for years trying to solve a problem.

But the average person probably never thinks that the talent that these people possess is actually more than the effort they put in, no matter how incredible their efforts seem to ordinary people.
