The military-industrial scientific research system of the academic master.

It is easy to say that everything is completely open, but it also requires proper methods and approaches.

Although Chang Haonan and Perelman's proof of the Poincare conjecture is simpler and easier to understand than the method proposed by the latter in the previous life, it still requires a certain amount of topological knowledge to understand.

At least 99.99% of the people on earth definitely have no hope.

Moreover, the length of the compiled article is at least several dozen pages.

Considering that Chang Haonan also used some numerical calculation methods in the final solution process, an appendix should be added to supplement and explain the calculation procedure.

The final complete version will definitely be over a hundred pages.

Therefore, traditional media such as radio, television, newspapers, etc., cannot be relied upon.

Can you imagine a female news anchor reading a math paper from beginning to end with a smile on her face?

Haonan can't go against the normal.

So we still have to rely on the Internet.

And when it comes to completely open academic websites...

no doubt.

arXiv.

Although this was originally a website designed to meet the needs of researchers in the computer field, by 2000, its content had gradually expanded to include other disciplines such as physics, mathematics, and biology, and it had gained considerable recognition in the academic community.

Of course, in addition to arXiv, the same document will be uploaded to the official websites of Beijing University of Aeronautics and Astronautics and the Steklov Institute of Mathematics at a later time.

When Chang Haonan sent this proposal to Perelman via email, he soon received a reply from him.

Different from the usual concise and concise style.

This time, perhaps because he had finally realized his long-cherished wish, or perhaps because of the joy of meeting a soulmate, in short, Perelman's reply this time was not only long, but also had a rare excitement between the lines.

[In fact, it is also my wish to publish the results through arXiv instead of directly in a mathematics journal, but considering that this historic achievement was completed by the two of us, I still decided to fully respect your opinion...]

[I am very happy to see that you have made the same decision as me, which shows that we are similar not only in academic level but also in academic pursuits. For me, this joy is no less than solving the Poincare theorem itself...]

This email once again confirmed Chang Haonan’s previous thoughts——

Perelman was not a loner, he just rarely met people with whom he could communicate with on an equal footing in terms of ideas.

"Then... prepare to submit your article..."

Chang Haonan closed the email page and began to organize the contents on the draft paper into the computer bit by bit...

Three days.

Another three days.

Chang Haonan finally completed the final check and uploaded the .pdf document to the website.

Compared to many magazine submission websites that require content to be copied and pasted onto a web page, arXiv allows files to be uploaded directly, which is quite user-friendly.

then……

Click Submit!

arXiv does not have a peer review process, so uploaded documents will be seen by researchers who are interested in related fields at the first time.

"what--"

After doing all this, Chang Haonan yawned deeply.

Fortunately, when the computing center was built, a temporary dormitory was set up on the same floor as the computer room.

Otherwise, I might have to sleep on the floor during this period.

But even so, I couldn't sleep well when I had something on my mind.

Under these circumstances, we worked non-stop for more than half a month.

Even he felt the fatigue coming like a tide the moment he relaxed.

Before leaving the computer room, Chang Haonan refreshed the webpage one last time.

I found that in less than a minute, the number of readings had exceeded 100.

Obviously, although the corresponding European and American time is either morning or midnight, such a heavy paper will obviously not lack attention...

……

After coming out of the computer room, Chang Haonan was originally planning to contact Zhu Yada directly and ask the latter to take him home.

As a result, he met Tang Lintian in the corridor, who came to his house for the umpteenth time.

"Professor Chang... Professor Chang?"

Liu Chenchen was repeating to Tang Lintian what Chang Haonan had said before he went into "retreat", that no one should disturb him.

As a result, he had only said half of his words when he saw Chang Haonan walking out from the other side of the work area.

"Professor Chang, what..."

Tang Lintian on the opposite side actually just came over after lunch and didn't have much hope.

For a moment, I didn't even react to what Liu Chenchen was saying.

But he soon noticed that the other person's eyes were focused behind him.

So he turned back suddenly.

Then the pupils shrank:

"Professor Chang, I finally got you here..."

Tang Lintian strode forward and walked in front of Chang Haonan:

"You've been out of contact for more than half a month. What if something urgent happens..."

Before he could finish, Chang Haonan waved his hand tiredly:

"If anyone calls the red phone in my office, Teacher Liu will notify me."

"Since the phone didn't ring, it means the sky won't fall..."

After finishing speaking, Chang Haonan turned to look at Tang Lintian next to him:

"Principal Tang came to see me this time because..."

"Oh……"

Tang Lintian was stunned at first, then replied with a smile:

"Originally, last week, I saw in the newspaper that some American mathematics institute was offering a reward of $100 million for seven difficult mathematical problems. I wanted to come and ask you if the Poincare conjecture that you and Professor Perelman were trying to solve might be among them. But I didn't see you for several times in a row."

"Later, I almost developed a habit of coming over every day to see if you were out... but I even forgot to take the newspaper..."

There is a legend that if you do something for 21 consecutive days you will develop a habit.

Then Tang Lintian is indeed fast now...

At this time, Liu Chenchen also interrupted:

"I still have that newspaper here, if you need it..."

"Need not."

Chang Haonan shook his head slightly:

"There are computers in the computer room that can connect to the Internet. I am just in seclusion, not cutting off contact with the outside world."

"The seven great mathematical problems of the millennium. I know that."

In fact, apart from contacting Perelman, he was basically in a state of isolation during this period.

It was only when Tang Lintian mentioned it that he remembered this matter.

But it’s too troublesome to explain, so I just said I saw it on the Internet.

"The Poincare conjecture..."

"If nothing unexpected happens, it should be inside."

Chang Haonan's tone was quite firm.

Tang Lintian's eyes sparkled.

The Millennium Problem, with its $100 million reward, has indeed had a considerable impact.

One day, the news broadcast even reported the incident in three sentences during the briefing segment.

If a professor from Beijing University of Aeronautics and Astronautics solves one of these problems before the hype has completely passed...

Thinking of this, he immediately asked:

"Then... after you solve this problem, will it be... the first..."

Tang Lintian pointed at Chang Haonan, then pointed outside, his words becoming a little incoherent.

Whenever he thought of that scene, the corners of his mouth couldn't help but curl up.

If there weren't two people in front of me, I would probably have to perform a dance.

However, what Tang Lintian never expected was...

"No need to wait any longer..."

Chang Haonan covered his mouth and yawned:

"We have solved it..."

His tone was so flat, as if he was saying, "I ate two fried dough sticks and drank a bowl of soy milk this morning."

So much so that Tang Lintian didn't even react at the first moment.

"what?"

"Solved...what?"

But in an instant, he realized the answer to his question.

"and many more……"

Tang Lintian was shocked:

"You mean ... Poincare ..."

He had been trying very hard to restrain himself just now.

Now that he was frightened by Chang Haonan, his hands and feet were completely out of control.

"Yes... the paper has been posted on arXiv, and has not been published by any journal, so it is available now."

Chang Haonan looked at Tang Lintian, who was startled and trembling all over, with sleepy eyes:

"Let me rest for two days, then I'll send you the manuscript and post it on our college's website..."

After he finished speaking, he walked out the door unsteadily, regardless of Tang Lintian who was unable to speak or move...

It was a long time before Tang Lin came back to his senses.

"Secretary Liu, do you still remember the Millennium Mathematics Conference...when was it held?"

"May 5th."

Liu Chenchen answered almost without thinking.

She knew that her boss was working on a difficult math problem. Although as a liberal arts student she didn't know what it was specifically, she still followed the news closely.

"So...what day is today?"

After asking this question, they both turned their heads at the same time and looked at the electronic perpetual calendar hanging at the end of the corridor.

September 2000, 5…
