If the University gives Qin Luo the first feeling of pastoral, then the second feeling is academic.

In the University, there is a special lecture hall, which is hung with numerous blackboards, which prove to be world-class problems.

Goldbach orientation, Riemann conjecture, corner Valley conjecture

However, before he was halfway around, he was attracted by a blackboard.

"Proof of twin primes, by Tesla cage."

“……”

Qin Luo:???

Honey, it can't be so clever.

Seeing the proof on the blackboard and the familiar name, Qin Luo was shocked.

Have twin primes been proved? The scroll he got was just an empty joy?

It's even more exciting than gambling.

One is poor, two is rich, and three is selling underpants.

Qin Luo has the idea of selling underwear now.

Unable to hold his curiosity, Qin Luo left the team and walked slowly towards the blackboard.

Just as Qin Luogang came to the blackboard and was ready to do a good research, a young man came over.

He was dressed in a black suit, with gold rimmed eyes, meticulous hair care, and a smiling face.

Give people a kind of unspeakable affinity.

However, Qin Luo is not very cold to him.

The reason is simple. He's three-thirds like Tesla, a blonde man, and he's very good-looking.

"Are you interested in twin primes, too?" He asked with a smile.

"Yes." Qin Luo nodded and put his eyes back on the blackboard.

"Tesla cage, University of Birmingham student, PhD, what's your name?" The young man held out his hand and said with a smile.

Sure enough, birds of a feather flock together, and those who look good are relatives.

Qin Luo didn't want to talk to him, but as a gentleman, he still reached out and shook his hand: "qinluo, Beishan NO.4 middle school is a student."

"Beishan NO.4 middle school? Is there such a university in the world? "

"High school, actually."

“……” Cage opened his mouth, feeling speechless.

Originally, he thought he met a Taoist friend with the same ideals, but this Taoist friend was only a high school student.

Ah - he doesn't even know what twin primes are.

The smile on the young man's face is still brilliant, but the bottom of his eyes can't be checked by a flash of disdain: "to participate in the IMO competition?"

"That's right."

"Nice to meet you."

"Me too..." Qin Luo nodded with a smile and then looked at the blackboard.

It is different from the disintegration process in Qin Luo's thought.

He proved twin prime numbers with a method called "backward mathematics".

It is necessary to envision a holistic approach from the conclusion and then from the conclusion.

This man, Tesla cage, presupposes the existence of twin primes.

Then on this basis step by step, it is proved that twin prime pairs are infinite.

Seeing this, Qin Luo scorned to smile. He finally knew why the conclusion made by the other party only appeared on the blackboard, not in the world-famous "Mathematical Journal".

Because he made a fatal mistake, even though his process is very simple, the logic is very clear, and the conclusion is correct, but he can not prove the twin prime number after all!

The twin prime number is a conjecture originally. He is waiting for the proof. There is no reason to imagine that the twin prime number is infinite in advance and then prove it step by step.
