Chapter 761 The eve of the military parade

"I personally think...it shouldn't be a big problem."

Facing Ding Gaoheng's question, Chang Haonan touched his chin and thought for a moment:

"Unless their editor drank too much and didn't send my article to the experts in differential geometry."

In fact, in the 90s, when his article was submitted, no matter who it was submitted to, in the end, it would most likely be handed over to a few people for review.

It's nothing more than a difference in efficiency.

Ding Gaoheng nodded.

If others express their opinions in this way, he may still have some concerns.

But Chang Haonan has always left room for speech and has never lied. Since he can make such a statement, he is obviously quite confident.

"When will it be published?"

Ding Gaoheng asked with concern.

"It's hard to say..."

Chang Haonan shook his head:

"Logically speaking, my proof process is only an expansion of the Ricci flow, and it has not reached the level of establishing a new theoretical framework. Even... uh... in short, it is very useful to mathematicians who study differential geometry, especially the Poincaré conjecture. There shouldn’t be any obstacles to understanding it.”

"But I heard that those big guys who are engaged in theoretical mathematics have weird tempers. There is no guarantee that they can't find someone or they have something to do. I can only say that if everything goes well, considering that the annual journal of mathematics is published bimonthly, then it will be best to It should be published in the sixth issue of this year at the end of November soon.”

Ding Gaoheng was visibly relieved when he heard that the publication time was calculated in months instead of years.

Chang Haonan also paused for a moment before continuing:

"I'm not in a hurry about this. It's originally a by-product of studying manifold learning. After the National Day, my focus should be on finishing the Turbofan 10 project, as well as the data mining algorithm just mentioned. This is application-oriented. Stronger projects have higher value at this stage.”

Not to mention just two lemmas, even if the Poincaré conjecture is really proved, it is not a particularly urgent matter for China today.

Of course, this does not mean that the Poincaré conjecture has no practical significance.

On the contrary, Poincaré's conjecture is widely used in fields such as computers, engineering design, and biology.

Otherwise, it would not have been included in one of the Seven Millennium Puzzles seven months later.

But similar to the NS equation, which is also a millennium problem, even if a rigorous explanation from a mathematical perspective is not found, the engineering community can still use it first.

Moreover, considering that the Poincaré conjecture requires a "proof" rather than a "solution", its engineering application is simpler than the NS equation.

I'll just assume it's true.

If you find out later that it doesn't hold true, just find a way to make corrections.

Furthermore, as a reborn person, Chang Haonan clearly knows that the Poincaré conjecture is true.

In a previous life, it was proven by Russian mathematician Grigory Perelman in 2003.

He did not submit his manuscript to any mathematics journal, but published three consecutive papers directly on the Internet.

Since he proposed almost a whole new set of theories during the proof process, it took other mathematicians nearly three years to finally confirm that his proof process was correct.

But before that, in 2005, Perelman had entered seclusion, and no one knew his whereabouts.

Neither the $100 million prize, the title of academician of the Russian Academy of Sciences, nor the Fields Medal could make him reappear.

In fact, the greater value of Poincaré's conjecture lies in physics, such as providing a mathematical foundation for string theory and quantum gravity theory.

And that will happen much later.

It is not too late to consider it after China's comprehensive national strength has been improved.

"Data mining...sounds like database-related technology?"

At Ding Gaoheng's age, it is somewhat difficult for him to do research, but it is not a problem to follow some cutting-edge topics.

He even has some idea of ​​the new terms in Chang Haonan's mouth.

"That's it."

Chang Haonan nodded:

"In layman's terms, it is to filter out the useful parts from massive amounts of complex information. The more useful ones at present may be...production line management and...search engines."

Of course there are deeper applications.

Such as image recognition, machine learning and even artificial intelligence.

But these will be true paintings in the new millennium.

It's like wheat hasn't been planted yet.

So Chang Haonan simply didn't mention it.

Let’s talk about it in the future when there is real hope of realizing it.

However, Ding Gaoheng’s focus is not on assembly line management:

"Search engine...like Google?"

"Yes, but this can only be regarded as one of the search engine technologies."

Chang Haonan replied.

It was also at this time that he suddenly realized something——

In 1999, China did not actually have its own search engine.

A degree was only established in January 2000.

Although search engines may seem inconspicuous, even until more than 20 years later, only China, the United States, South Korea and Russia in the world have their own independent technology search engine cores.

Of course, both Dou and Google gradually used their respective market monopolies to become advertising trolls. This is a story for another day.

But search engine technology itself is definitely positive.

Especially in the early days of Internet expansion, it greatly reduced the difficulty for beginners to get started.

After all, there is still a bit of a barrier to enter the URL directly into the address bar.

And if we can exert some influence on a certain degree during this critical period...

Not only can Torch Group make more money.

It also seems to help regulate the other party's future development.

Win-win.

It’s just that time is already a bit tight.

If a degree's core technology patent "Super File Retrieval System and Method" has been registered, it actually already has the most basic conditions for establishment. Chang Haonan can only start from improving performance.

No matter what, he had already kept this in mind.

……

After chatting all the way, the motorcade finally arrived at Wuqing Airport.

This is one of the seven military parade support airports in North China.

It is also the largest of them all.

Most fixed-wing aircraft, including the Bayi Aerobatic Team, will take off from here.

Several third-generation aircraft, including several, were also moved here from the originally planned Yangcun.

"Director Ding, Mr. Chang."

After the two got off the bus, Zheng Liangqun, wearing a pilot uniform, was already waiting nearby and saluted immediately when he saw the two.

Of course, it is mainly for Ding Gao Hengjing.

Chang Haonan was not a soldier, so he naturally couldn't return the favor. He just shook hands with Zheng Liangqun:

"Commander Zheng, are you... going to fight in person?"

"nature."

Zheng Liangqun nodded:

"I am the pilot of the interceptor echelon, and I have just returned home not long ago."

Theoretically, all military chiefs (excluding political commissars), including the Air Force Commander, have the ability to take off and fly.

But generally speaking, due to the existence of the 45-year-old grounding line, the highest military rank for a fighter pilot who can truly take to the skies is senior colonel.

After all, in peacetime, if an officer is promoted to major general step by step, he will be overage anyway.

However, as one of the only two pilots in the army who has participated in combat operations and quasi-combat operations, Zheng Liangqun happened to be promoted to major general under the age of 45.

And thus I got this once-in-a-lifetime opportunity.

"You have to personally participate in training, and you have to be responsible for management... You have worked hard too."

Although Ding Gaoheng is not Zheng Liangqun's direct leader, he is still a superior after all, so there is no problem in saying this.

"How can it be considered hard work... Others want this opportunity, but they still can't get it..."

Zheng Liangqun straightened his back and said with a smile on his face:

"Besides, Commander-in-Chief Li specially assigned three deputies to me, which is enough to ensure that we can pass over Tiananmen Square within seconds on October 1st!"

While several people were talking, the roar of an engine came from the horizon not far away.

Chang Haonan and Ding Gaoheng turned their heads at the same time.

It was 4 fighter-bombers preparing to land.

Although it was difficult to see clearly from a distance, Chang Haonan still remembered that Zheng Liangqun had said before that if it was a 4-machine rocket team, it would be the JH-7A that had just been trial-installed and entered service.

"Let's go, other formations are also returning home one after another, just go and have a look."

Zheng Liangqun's face showed a proud look:

"I have been a pilot for twenty years, and I have rarely seen such a spectacular scene!"
