Zhang Zhai, who had been silent all day, finally started to move again.

The most rare thing to crack a mathematical conjecture is a glimmer of inspiration. Compared with other scientific research, mathematical research relies heavily on the personal wisdom of mathematicians and that glimmer of inspiration.

Now Zhang Zhai has this glimmer of inspiration, and he immediately followed this glimmer of inspiration. With his powerful brain, he figured out the core idea. He only needs to follow this core idea to prove 1+1 and prove Goldbach.

Guess it's just a matter of time.

While Spider went to get his pen, Zhang Zhai picked up the dinner next to him and ate it in big gulps.

He hadn't eaten anything all day long, his stomach was churning, and the acid in his stomach was almost rising to his throat.

I was immersed in thinking about the problem before and didn't feel much. Now I woke up and I was so hungry that my chest was pressed against my back.

The dinner was quickly stuffed into his stomach as he devoured it voraciously.

A box of rice is put into the stomach, and there is something in the stomach, which makes me feel much better immediately.

Just as Zhang Zhai finished his meal, there was a knock on the door.

"Dong dong...Mr. Zhang, the pen you want,"

Spider placed a box of gel pens next to it.

"Well, Spider, from now on, there is no emergency. I don't want anyone to show up and disturb me." Zhang Zhai stared at Spider and said in a deep voice.

Spider was a little hesitant. Zhang Zhai had a criminal record. If Zhang Zhai fainted in the lounge again, he would be the one to blame.

"Mr. Zhang...this..."

"Except if there is any abnormal movement, do you understand?" Zhang Zhai said,

"Don't worry, I'm sober now. This time the situation is different from before."

"Okay, Mr. Zhang, I understand!" Spider exited the lounge.

Zhang Zhai shook his head, then picked up the pen, turned back and looked at the pile of manuscript paper in his hand.

Looking at Chen's theorem at the end of the manuscript paper, Zhang Zhai smiled.

"Wow..." Zhang Zhai tore off the manuscript paper and let it fall to a corner of the room.

"1+1...I'm here." Zhang Zhai shook his sore wrist and tightened his grip on the pen.

The pen tip is close to the paper, and the first stroke that proves Goldbach's conjecture appears on the manuscript paper.

"Wow..."

Zhang Zhai is very fast, and the most critical steps have already appeared in his mind in advance. What he has to do now is to enrich it, then connect it into a logical and rigorous proof process, and record it!

One page, two pages... As Zhang Zhai's brush strokes continued to cross the paper, the steps of proof slowly appeared.

The entire proof process is undoubtedly very complicated, otherwise it would not have trapped mathematicians for two hundred years.

As time goes by, more and more papers are used to prove 1+1.

One hour...two hours.

Ten pages...twenty pages...

From evening to late at night, Zhang Zhai's hand writing movements never stopped, but it became slower and slower as he went to the back.

"Huh..." Zhang Zhai let out a long breath and shook his sore hand.

"It's just a little bit... just a little bit close!" Zhang Zhai's eyes showed determination and a hint of madness. From the beginning to the end, his eyes never left the manuscript paper.

Twenty pages...thirty pages...

The time passed from late night to early morning, and you could feel from the only window in the lounge that it was almost dawn outside.

But Zhang Zhai still didn't stop. He was like a machine, recording the steps of proof on paper without stopping.

Zhang Zhai's eyes were a little crazy, and there was a smile on his lips. His face was pale from staying up late, but his ears were also bloodshot from excitement.

Zhang Zhai seemed to be tireless, constantly calculating, calculating, and writing.

Sudden!

Zhang Zhai's hand stopped for a moment, he paused, and he frowned again.

He found a detail problem, a small logical error!

This small detail is undoubtedly extremely fatal in the process of rigorous mathematical proof.

Perhaps the proof can be completed by ignoring this small detail, but Zhang Zhai would not do that.

So, he stopped, frowned, and stared at the page.

He just stared at it for ten minutes, and the detail issue was solved.

But the price was that Zhang Zhai tore up the proof steps on ten pages of manuscript paper and started over.

…

The sky outside gradually turned from black to white, and the steps of proof were finally coming to an end.

…

finally!

Zhang Zhai's hand stopped again!

The tip of the pen was hanging in the air, and my hand was shaking violently.

Writing continuously for several hours made Zhang Zhai's hand muscles very sore.

But at this time, Zhang Zhai ignored the pain and showed a bright smile on his face.

"Succeeded..."

As he spoke, Zhang Zhai's right hand that was hanging in the air fell down again. With his trembling right hand, he crookedly wrote at the bottom of the 37th draft paper:

"From this, it can be proved: N=P1+P2"

Translated into text, the meaning is: Any sufficiently large even number can be expressed as the sum of two prime numbers (prime numbers).

This formula is extremely simple, and the handwriting is not beautiful, but Zhang Zhai spent 37 pages of manuscript paper to prove this step. This does not include the steps before 1+1. The entire proof process took nearly two hundred pages.

Manuscript paper.

Zhang Zhai looked at the last step and laughed, "The proof of Goldbach's conjecture is complete. It seems that I have unfortunately won this jewel in the crown of mathematics."

After 276 years, Goldbach's conjecture was finally solved by Zhang Zhai.

This means not only that Goldbach's conjecture will become Goldbach's theorem or Zhang Zhai's theorem.

It also represents many formulas that Zhang Zhai innovated in the proof process, which will also be ordered as Zhang Zhai's theorem and Zhang Zhai's formula.

A few years later, students studying mathematics will hear this sentence: "Zhang Zhai's theorem is very important. It must be tested in the exam and must be used flexibly!"

At this time, it was already dawn. Zhang Zhai looked at the manuscript papers in the room, thinking about the possible scenes, and laughed heartily.

After a long time, Zhang Zhai stood up from the ground.

The next second, Zhang Zhai's feet went weak and he almost fell down. Fortunately, he held on to the bed next to him in time.

"Father, are you okay? Do you need me to call for treatment?" A1 observed the situation and immediately asked.

Zhang Zhai closed his eyes and shook his head: "It's okay, it's just because I stood up suddenly after sitting for a long time, my brain is congested, and I'm a little dizzy because I didn't rest."

After a long time, Zhang Zhai adapted and opened his eyes again.

"A1, scan my previous proof process and check whether there are any logical loopholes in my proof process."

"Okay, father." A1 responded.

Zhang Zhai bent down, picked up the 37 pages of manuscript paper proving the "1+1" step, and asked A1 to scan it.

It took a total of five minutes. After the A1 scan was completed, computing resources were immediately called to verify Zhang Zhai's proof process.

"Father, the proof process is correct. Congratulations on overcoming a mathematical difficulty." A1 said.

With a smile on his face, Zhang Zhai waved his hand and said: "A1, based on the core steps of my proof, write a paper on proving Goldbach's conjecture, and then submit it to any top mathematics journal."

"Okay, Father."

"A paper has been generated according to your request. The first author's name is: Zhang Zhai. Do you need to check it again?"

"unnecessary."

"Okay, Dad, I have sent the paper to the "Annals of Mathematics" for you."

Zhang Zhai received the answer, nodded and said no more.

He fell directly onto the bed and fell asleep within a few minutes.

He was really tired. Thinking to the limit for a whole day and two nights made him very tired.
Chapter completed!
