Chapter 821 The Project Has Been Solved Before It Even Started?
In the end, after Perelman calculated alone for nearly half an hour, out of the professionalism of a scholar, he stood up again and finished what was on the blackboard.
However, anyone can see it.
In this last part, he was already quite absent-minded.
Obviously, what was just written on the paper is extremely important.
So much so that it distracted most of his attention.
Fortunately, this method of proof is quite smooth to understand, and it didn't cause any other setbacks.
This report meeting was overall a success.
Especially for Tang Lintian.
Although he didn't fully understand.
But a new theorem was first disclosed at the little-known Beijing Hang University lecture conference.
This incident itself is full of legend.
He has even begun to think about how to do a wave of publicity.
Tang Lintian himself did not understand theoretical mathematics, and most of the experts present just now came from other schools.
The envious looks from a dozen of his colleagues really made him feel good, but when it came time to really want to find someone of his own to help him with things, it was a bit troublesome.
Therefore, immediately after the report meeting, Tang Lintian showed a flexibility that was completely unbecoming of a middle-aged man in his fifties. Like a slow arrow leaving the string, he rushed out of his seat, preparing to stop Zhenghe Pei. Lehrman left Chang Haonan side by side.
"Professor Chang!"
After hurrying and hurriedly, I finally stopped the other party at the door of the auditorium.
Chang Haonan turned around and saw Tang Lintian gasping for breath behind him. Only then did he realize that he had been too distracted and seemed to have left without saying hello.
It's really inappropriate.
"Professor Chang, I..."
Before Tang Lintian could say anything about wanting Chang Haonan to help write a draft, he was interrupted by the latter.
"Principal Tang, I'm sorry, but Professor Perelman and I will not attend tonight's reception banquet."
Regarding Chang Haonan's request, Tang Lintian basically agreed first and then thought about it, so he nodded almost without thinking:
"good……"
Then I realized what outrageous thing I had agreed to——
Hey guys, I've asked all the schools in the country that have top-notch math departments.
People come from as close as outside the Fourth Ring Road and as far away as from Hunan and Min provinces. They can’t just come to see my old face, right?
As a result, you two VVVIPs can’t come?
Tang Lintian was numb, and the expression on his face that was full of joy a second ago suddenly froze.
"Wait a moment……"
"How……"
"Didn't you just..."
He has begun to reflect on whether he did not provide good hospitality, which led to Perelman, a boss who is said to have an eccentric personality, to have opinions.
Chang Haonan's mind was focused on the train of thought just now, and he didn't have the energy to explain too much. He just waved his hand:
"Several other people from the Styklov Institute of Mathematics will still attend the dinner."
"As for the two of us..."
He glanced at Perelman, who was contemplating, and showed a mysterious smile:
"We're on the verge of uncovering how the world works."
Solving a complex mathematical problem often takes months or even years.
But most of the time is actually spent on "calculation".
In the past, we relied on paper and pen, but now we can certainly rely on supercomputing.
However, the reason why mathematics cannot be equated with arithmetic is that there are still some truly critical steps that cannot be solved by calculation alone.
Need to rely on inspiration.
Now, Chang Haonan and Perelman have undoubtedly caught the tail of inspiration.
Naturally, it is impossible to waste time for a mere dinner party.
Tang Lintian was stunned.
At first glance, this statement seems to be boundless.
If it came from another person, he would definitely think that he was making a fool of himself.
But Chang Haonan...
In Tang Lintian's impression, the other party never seemed to exaggerate his research——
Even in the proposal report, which generally requires value sublimation, it has never been done.
Of course, Chang Haonan's proposal report will also be valuable.
But the problem is that other people's values are just casual remarks.
And his value can really be realized...
Thinking of this, Tang Lintian took a deep breath and nodded.
"good."
…
The lights in Chang Haonan's office stayed on all night.
Perelman's absence from the dinner that day also triggered a series of speculations.
Although Beijing Airlines publicly stated that the professor was unwell and was unable to attend, rumors and rumors will not care what explanation you give.
Almost that night, rumors spread that "Professor Perelman was dissatisfied with the exaggerated atmosphere of Chinese academic circles and angrily refused to attend the dinner."
And what happened next surprised almost everyone——
The next day, the visiting team from the Steklov Institute of Mathematics ended their trip early and returned to Moscow!
Now, in the eyes of the ignorant people, and even some people who participated in the report meeting and banquet that day, it was simply a real deal.
For a time, the media who caught the clues of the gossip pounced on the news like sharks smelling blood.
After sending Perelman and his team away and dealing with a group of media who couldn't get rid of him, Tang Lincai went to the computer room of the computing center and found Chang Haonan.
One night's collision of ideas generated enough sparks to set the entire mathematical world on fire.
That’s pretty much it for inspiration.
There are only some complicated but relatively low-tech jobs left.
What Chang Haonan is doing at this time is to import the calculation program into the supercomputer——
The method he and Perelman finally decided on was to use surgical Ricci flow. This process is quite special. It requires first cutting off a "neck" area in the manifold and then "gluing" it to the "top". Thereby expanding the solution interval.
The key to the problem is to find a suitable set of "necks" and "tops" and choose the correct canonical neighborhood radius.
This process can of course also be done with pen and paper.
But for mathematicians who are about to enter the 21st century.
Yes, but not necessary.
The computer can do it for you.
Especially for Chang Haonan who is not ready to devote all his energy to this, it is the best way to "be lazy".
"My Professor Chang, you have given me strength this time..."
Tang Lintian sat down on the chair opposite Chang Haonan.
Probably because he was anxious to get angry, and the computer room was relatively hot, his face turned red as if he had just been drunk, so he took off his cotton hat and used ear protection as a fan to fan himself:
"The leaders of several brother universities have called me to ask me what's going on. China Youth Daily had made an appointment to write a special report on this matter, but it turned out that you two disappeared last night. This morning, they The leaders also came over to ask questions and said that even the page had been reserved..."
After pouring out his bitter words, Tang Lintian turned his head and glanced secretly at the opposite side.
It turned out that Chang Haonan looked hard-hearted and did not react to his complaints.
After failing miserably, he could only cough twice, take off his cotton-padded clothes, and then sit up straight:
"Professor Chang, to be honest, although I can still resist the pressure this time, you can at least reveal what you are holding back this time. I also have something to think about, right?"
"call--"
After hearing what he said, Chang Haonan finally raised his head and breathed a sigh of relief:
"Two things."
"First, I plan to use the three-dimensional sphere theorem derived yesterday to optimize the previously developed manifold learning algorithm and extend the applicability of the algorithm from high-dimensional space to three-dimensional and below."
"Well……"
Tang Lintian stopped moving his hands, and his face showed a bit of confusion:
"Can you...explain?"
He is also a well-known expert in the aviation field, but at this time he feels as if he has never gone to school.
Although he knew every word the other person said, he didn't understand it when put together.
"That is, the data obtained in the three-dimensional space can be further reduced in dimensionality and then handed over to the computer for processing."
Chang Haonan was already busy with important things at this time, so he explained patiently:
"Specifically, Professor Meng's hyperspectral remote sensing data feature extraction project is basically finished."
"ah?"
Tang Lintian was shocked:
"End...end the question?"
After being stunned for a few seconds, he continued:
"But that project has just been applied for, and it hasn't even been officially launched yet?"
Finishing the project before starting the project is absolutely unprecedented, and I'm afraid it will be difficult for others to do it in the future.
Of course, this refers to other comers.
"Hey..."
Chang Haonan raised his hand to straighten his somewhat messy hair:
"The main reason is that I suddenly got the inspiration yesterday. I didn't expect it to happen so quickly."
Fortunately, Tang Lintian was used to Chang Haonan's unfavorable operations and quickly convinced himself to calm down.
"Then now..."
He pointed to the computer room next door where the fan was roaring:
"Are you testing the algorithm you just mentioned?"
Speaking of this, Tang Lintian suddenly reacted:
"No, this matter has nothing to do with Perelman, right?"
"Oh...these are the second things."
Chang Haonan leaned back on the chair, waved his hands gently, and said casually:
"We are trying...no, we are trying to conquer the Poincaré conjecture."
The hat in Tang Lintian's hand fell to the ground.
