Chapter 761 The Eve of the Military Parade
“I personally think... it shouldn’t be a big problem.”
Faced with 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 who studied differential geometry."
In fact, in the 1990s, his article was submitted, regardless of the submission. Who should I give it to? In the end, it will go round and round, and it will most likely be handed over to a few people for review.
It's nothing more than a difference in efficiency.
Ding Gaoheng nodded.
If someone else expresses his position like this, he may 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 just an expansion of the Ricci flow. , it has not reached the level of establishing a new theoretical framework, even... uh... In short, there should be no obstacles to understanding it for mathematicians who study differential geometry, especially the Poincaré conjecture. "
"But I heard that those big guys who are engaged in theoretical mathematics have strange tempers, and there is no guarantee that they just can't find someone, or they have something to do. I can only say that if everything goes well, considering that the Mathematics Annual is published bimonthly, then It should be published in the sixth issue of this year at the end of November at the earliest.”
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, and then continued:
"I am not in a hurry about this. It is originally a by-product of studying manifold learning. After the National Day, my work focus will be It should be put at the end of the Turbofan 10 project, as well as the data mining algorithm just mentioned. This is a relatively strong application project and is of higher value at this stage. "
Don't say it. There are 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 7 months later.
But similar to the N-S 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 N-S 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.
I did not submit to any mathematics journals, but published 3 consecutive papers directly on the Internet.
Because he almost proposed a whole new set of theories during the proof process, it took other mathematicians nearly 3 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.
No matter the $1 million prize, the title of academician of the Russian Academy of Sciences, or the Fields Medal, they could not 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 a database-related technology?"
At Ding Gaoheng's age, he is a little unable to do research, but it is not a problem to follow some cutting-edge topics.
I even have some idea of the new terms in Chang Haonan's mouth.
"So be 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.
For example, image recognition, machine learning and even artificial intelligence.
But these are true paintings in this 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 pipeline management:
“The search engine... is 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.
Some 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 the expansion of the Internet, 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 convoy finally arrived at Wuqing Airport.
This is one of the seven military parade support airports in North China.
Also the largest one among them.
Most fixed-wing aircraft, including the Bayi Aerobatic Team, will take off from here.
Including several third-generation aircraft, they were also moved here from the originally planned Yangcun.
"Director Ding, Mr. Chang."
After the two got off the car, 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 had no way to return the salute. He just shook hands with Zheng Liangqun:
"Commander Zheng, are you... going to fight in person?"
"Of course."
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 really take to the sky is senior colonel.
After all, in peacetime, an officer is promoted to major general step by step, and he is 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.
This is a once-in-a-lifetime opportunity.
"You have to personally participate in training, and you have to be responsible for management... You have worked hard."
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:
< br>“Besides, Commander-in-Chief Li has 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 is 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 look of satisfaction:
"I have been a pilot for twenty years, and I have rarely seen such a spectacular scene!"
