Lin Fan looked at the system list, closed his eyes, and fell into a deep sleep.
…
The next day, a ray of warm morning sun shone gently into dormitory 104 through the window.
"Jingle Bell!"
Almost at the same time, three different bells rang in the dormitory.
Then, Ma Zhong, Song Yi and Zheng Jinbao, who were sleeping soundly, sat up from the bed together and quickly dressed.
Lin Fan couldn't help but wonder: "What's wrong with you?"
Yesterday, they had been grinding for a long time before reluctantly getting up.
Today, he is completely different.
"Teacher Tiantian's class is Teacher Tiantian's class!" Zheng Jinbao shouted.
Lin Fan was still puzzled, but he still dressed and washed.
Walking on the way to the classroom, Lin Fan looked at the anxious steps of the three of them and asked, "Is this teacher Tiantian's class important?"
"Important! So important! If I don't see Teacher Tiantian for a day, I feel uncomfortable all over!" Zheng Jinbao said.
Song Yi said: "Brother Fan, hurry up and leave! Otherwise, there will be no seats left later."
No seats
College classrooms are very spacious.
Lin Fan has been attending class for the past two days, and there have been many empty seats in the classroom.
Will there be no seats today
Lin Fan finally came to the classroom with full of doubts.
It was only then that he understood why Song Yi and others said that.
There are still ten minutes left before class begins.
However, the classroom was already dark and full of people.
Zheng Jinbao pointed to the seat in the last row and said excitedly: "There are four more seats there. Come on, let's get there quickly and don't let anyone else take them."
When Lin Fan and others sat down, all seats were occupied.
People who entered the classroom again had no choice but to sigh and leave after seeing the seating situation.
Lin Fan asked: "Why are there so many people in this teacher's class?"
"You'll know later." Song Yi said excitedly.
"Jingle Bell!"
At this time, the school bell rang.
In an instant, the originally noisy classroom became as quiet as a pindrop.
"Tap tap tap!"
There was a crisp sound of footsteps, approaching from far away.
Soon, a very beautiful woman came to the podium.
She has a handful of waterfall-like hair, a pretty face that can be broken by a bullet, and has willow-leaf eyebrows carefully carved by God, red phoenix eyes, a small nose, and a smart cherry mouth.
A white dress outlines her perfect figure (oYo).
In addition, she exudes a special charm... As long as people take a look at it, they can't move their heads away at all.
Lin Fan couldn't help but observe with the eyes of truth.
Appearance: 98
Favorability: 60
98 looks!
Almost perfect score!
The fish sinks and the wild goose falls, the moon closes and the flowers shy. Perhaps, he was talking about her.
It's no wonder that the students in the class are so anxious to attend her class.
Favorability, 60? Reached the passing line of 60 points! Does she seem to have a good impression of herself
Could it be that this is a teacher who treats every student as a friend
At this time, Hu Tian, standing on the podium, said: "Today, we will continue to explain advanced algebra..."
Her voice, like her name, is sweet and magnetic, making people don't want to miss even a single word.
After a while, Hu Tian wrote a question on the blackboard: Find all prime numbers p, q, r, so that p^q+p^r is a perfect square number.
"Everyone can try to answer it." Hu Tian said.
All the students immediately picked up their pens and started writing on the scratch paper.
They thought of using the shortest time to solve the difficult problem and get Hu Tian's attention.
However, soon, all the students started scratching their heads.
Because they simply don't know how to answer.
Zheng Jinbao said anxiously: "Ma Zhong, haven't you answered it yet? It's been so long!"
Ma Zhong said: "Don't worry!"
"Don't be overtaken by others! If Ma Zhong can't answer it, then I hope no one can answer it!" Song Yi prayed silently.
Hu Tian's bright eyes glanced around the classroom, seemingly looking for someone who could answer the question.
Unfortunately, no one raised their hand to answer the question.
So, Hu Tian said: "Lin Fan, can you come up and give me an answer?"
Lin Fan slowly stood up.
Suddenly, all the students' eyes fell on Lin Fan.
That is envy, that is jealousy!
Lin Fan didn't understand why Hu Tian suddenly called his name.
You don’t seem to have raised your hand
Lin Fan first looked at the topic on the blackboard, thought for a moment, then walked to the podium, picked up the chalk and wrote quickly.
If q=r, then p^q+p^r=2p^q, so p=2 and q is a prime number.
Therefore (2, q, q) is a ternary prime array that satisfies the conditions...
…
To sum up:
(2, 2, 5), (2, 5, 2);
(3, 2, 3), (3, 3, 2);
(2, q, q), (q》=3)
Soon, a large number of calculations were written on the blackboard, and the answer was finally obtained.
Hu Dian nodded and said: "The answer is very correct, and it is simpler than the calculation method I thought."
Lin Fan said: "However, this is still not the easiest way to solve the problem."
"Oh?" Hu Tian became interested immediately.
Then, under Hu Tian's expectant gaze, Lin Fan wrote out the nearly half-simplified steps to solve the problem.
After Hu Tian saw it, her beautiful eyes lit up slightly and she exclaimed: "I never thought prime numbers could be calculated like this..."
After thinking for a while, Hu Tian added: "If we use this method, maybe..."
Hu Tian couldn't help but write quickly on the blackboard.
Q=p1m1+b1=p2m2+b2… pkmk+bk
Q=41=2m+1=3m+2=5m+1
…
Not long after, Hu Tian stopped writing the chalk in his hand.
Then, he looked at Lin Fan with help-seeking eyes.
Lin Fan said: "Twin prime number conjecture?"
Since gaining professor-level mathematics experience, he has read a lot of mathematics-related materials, and of course he knows about the world-class problem - the twin prime number conjecture.
Hu Diantian nodded and said, "Yes."
Lin Fan picked up the chalk under Hu Tian and started writing quickly.
However, even if Lin Fan has professor-level mathematics experience and absolute concentration, if he fails to trigger the 5% flash of inspiration, he will not be able to solve the twin prime number conjecture at all.
After a while, Lin Fan also stopped.
Hu Tian said: "If the above calculation is replaced by p^q+xb=3m+2... what do you think?"
Lin Fan thought for a while, shook his head and said: "No, let's change it to 5p5m+p^q..."
The two discussed and wrote down the steps to solve the problem.
Soon, the entire blackboard was filled with dense calculations.
