Chapter 259: I looked down on you before, but now I can’t afford it
University of New Hampshire, Department of Mathematics.
Zhang Yitang has been paying attention to Wang Donglai's news since he proved Huo Qi's guess.
He was becoming more and more shocked.
Until Goldbach’s guess was proven, Zhang Yitang was shocked beyond words.
The reasons are many and complex.
But the most important thing is that Wang Donglai proved that the topological group theory conjectured by Goldbach is very important to him, very important.
To put it bluntly, as long as he has a thorough understanding of topological group theory, he will be able to achieve a huge breakthrough in the proof of twin prime numbers. By then, he may not be unable to win the Fields Medal.
However, he did not participate in the Global Mathematicians Conference at that time and missed such a good opportunity.
Even after the fact, he used various means to analyze and study Wang Donglai's proof process, and he only made some slight breakthroughs.
During this period of time, he had been in his office, trying to achieve a breakthrough through the topological group theory information of Scale Claw, but he still fell short.
“Huh!”
With a long breath, Zhang Yitang put down the pen in his hand.
If an acquaintance could see what he looked like at this time, he would definitely be surprised.
Because he now has extremely dark circles under his eyes and his eyes are dull.
However, although he looked extremely tired, his energy and energy were not bad at all.
On the contrary, he looked quite excited. Weakness and excitement coexisted, revealing a sense of weirdness.
"What a pity, I wish I could have known about the existence of topological group theory earlier."
Zhang Yitang sighed in a low voice, his tone full of regret.
“What a pity! What a pity!”
After saying two regrets in succession, Zhang Yitang's eyes suddenly became firm, as if he had made some decision.
Taking out his mobile phone, Zhang Yitang dialed a number on the keyboard.
The owner of this number, he originally thought that he would never be contacted again.
But I didn’t expect that in such a short time, I would take the initiative to contact him.
Suppressing the distracting thoughts in his heart, Zhang Yitang had already dialed the number with his finger.
"Du~"
Every sound made Zhang Yitang feel nervous and uneasy.
For more than ten breaths, this moment became extremely long.
Finally, the call was connected.
“I thought I was wrong, but I didn’t expect you to call me, Lao Zhang.”
A cheerful voice came from the other end of the phone, but after hearing this, Zhang Yitang's face suddenly became a little ugly, mostly embarrassed.
"Song Yao, I heard that you are going to become a regular employee, congratulations!"
Although Zhang Yitang's face was a little ugly, it changed instantly, and he said congratulations in a familiar tone.
The person chatting with Zhang Yitang was Xu Songyao from Tangdu Jiaotong University.
"Lao Zhang, don't say that. The appointment has not been made yet. Who will serve as the principal is a matter for the organization to consider. No matter who is appointed, I will abide by the organization's decision!"
< br>
Xu Songyao did not accept Zhang Yitang's congratulations, but instead spoke in an official tone.
Zhang Yitang sighed inwardly. He was not a fool and could fully understand the meaning of Xu Songyao's words.
The last time I refused Xu Songyao's invitation, I undoubtedly refuted his face.
Although there is no enmity, the relationship between the two has become extremely cold.
Now, the two of them are just ordinary acquaintances, not even friends.
Zhang Yitang was already prepared for this and said, "Songyao, I saw an announcement from your school that academic discussions will be held in September. Is this true?"
< br>"This must be true. We are also drawing up the specific list of scholars to be invited."
Zhang Yitang took a deep breath and then asked calmly: "Songyao, I I see that your school has another announcement, saying that it invites domestic and foreign scholars to join your school’s senior staff. Are there any invitation conditions for the Institute of Mathematics?”
Xu Songyao on the other end of the phone seemed stunned, paused for a few breaths, and then said: “Because it’s an interview. We invite domestic and foreign scholars, so the invitation conditions are still being discussed, and the specifics have not been decided yet. There will still be some thresholds."
Zhang Yitang nodded and asked calmly: "Song. Yao, you know the direction of my research.”
"Before, I was short-sighted and missed the opportunity. Do I still have the opportunity now?"
After finishing speaking, Zhang Yitang quietly waited for Xu Songyao's reply.
Xu Songyao, who was at Jiaotong University in Tangdu at the moment, was also a little stunned. He didn't expect Zhang Yitang, who had such a tough temper, to say such a thing, but he figured it out in just a second.
Although Tangdu Jiaotong University is also one of the top universities in the country, at that time, Tangdu Jiaotong University only relied on its profound historical background, but its ranking was gradually declining, and it was obviously declining.
Even if Wang Donglai appears, many people don't think it will bring much change to Tangdu Jiaotong University.
But in just two years, the situation has changed dramatically.
The Institute of Advanced Mathematics was established at Jiaotong University in Tangdu, and Wang Donglai must be one of them.
With Wang Donglai’s current academic talent and achievements, the future development of the Department of Mathematics at Tangdu Jiaotong University is limitless.
Xu Songyao knows all this.
So, in just an instant, he understood Zhang Yitang's inner thoughts.
After pondering for a moment, Xu Songyao said: "Old Zhang, there is definitely an opportunity, but it depends on whether you can seize it."
A smile suddenly appeared on Zhang Yitang's face, and he said decisively : "Songyao, I understand. I'm going to resign from my job at the University of New Hampshire. I'll finish my work here and come back to China."
Hearing Zhang Yitang With such a statement, Xu Songyao's tone became gentler and he said: "Old Zhang, it's a good thing that you want to come back. It just so happens that you can come back to participate in academic seminars and see the development of domestic mathematics."
"That's right. In this way, after staying abroad for so many years, I also want to come back, and this happens to be a good opportunity."
Zhang Yitang said in agreement.
"Well, then contact me when you return to China." Xu Songyao said to Zhang Yitang.
“Okay!”
After hanging up the phone, Zhang Yitang started typing on the keyboard and quickly wrote a resignation letter.
On the other side of the ocean, at Jiaotong University in Tangdu, Xu Songyao had a cheerful smile on his face after hanging up the phone.
“It’s great, it’s really great!”
In the past few days, Xu Songyao has received a lot of phone calls. Some people congratulated him on his promotion, some were inquiring about him in a roundabout way, and some even showed kindness to him.
Among them, some came because of their own promotions, some came because of academic discussions, and some came because of the Institute of Advanced Mathematics at Tangdu Jiaotong University. Zhang Yitang's call was not the first. In the past few days, Xu Songyao's calls had not stopped.
There are not a few scholars who think the same as Zhang Yitang, but there are more domestic scholars and professors than foreign ones.
Among these people, Zhang Yitang is also the most talented in mathematics.
Xu Songyao has known Zhang Yitang for so many years, and he is very aware of Zhang Yitang's mathematical talent.
If it weren’t for proving twin prime numbers, Zhang Yitang would have made a breakthrough long ago in another field of mathematics.
From Xu Songyao's point of view, he naturally hopes that the scholars who join the Institute of Advanced Mathematics of Tangdu Jiaotong University will be as powerful as possible.
So, Xu Songyao is willing to accept Zhang Yitang.
However, the reason why he did not agree immediately was not only to whet Zhang Yitang's appetite, but also to respect Wang Donglai's ideas.
The core of the Institute of Advanced Mathematics is Wang Donglai.
Xu Songyao has never forgotten this. Although Wang Donglai is unwilling to assume a leadership position, he cannot do these things over Wang Donglai.
At least we should inform and discuss it in advance.
Thinking about it, Xu Songyao called Wang Donglai.
"Donglai, Professor Zhang Yitang from the University of New Hampshire is planning to return to China and join the school's Institute of Advanced Mathematics. What do you think?"
"I had invited him before, but he rejected it. Now I see that you have proved Goldbach's guess. You just called me and revealed this meaning."
Wang Donglai is currently at Galaxy Technology After looking through the company's reports, I received a call from Xu Songyao.
"Uncle Xu, you shouldn't ask me about this kind of thing. You are the principal. This matter should be decided by you. It doesn't matter if you ask me for my opinion."
Wang Donglai did not answer, but instead handed the decision-making power on this matter to Xu Songyao.
Hearing what Wang Donglai said, Xu Songyao said angrily: "The Institute of Advanced Mathematics in our school was prepared for you, and it was built because of you. You are the most important. So I have to listen to your opinion.”
"No, no, no!"
"Uncle Xu, please don't say that. I am only twenty years old. I am young and inexperienced. I don't understand many things. I am just a He’s just an ordinary professor. Uncle Xu, you can decide for yourself.”
"Besides, most of my energy will be put on other places in the future, and I will put aside mathematics for a while, so the school's Institute of Advanced Mathematics still needs the school to pay more attention to it."
Wang Donglai kept saying it He refused, he really didn't want to get involved in these things.
It’s trivial, a waste of energy, and of little benefit.
If possible, he would rather teach, so as to cultivate some talents.
Xu Songyao also heard the firmness in Wang Donglai's words, so he stopped forcing and said: "Okay, since you said so, then I will make a decision. Zhang Yitang is in Twin Prime Numbers academic attainments or Not bad, I believe that if I can understand your topological group theory, the proof is not far away.”
“That’s why he thought about returning to China and joining the school’s Institute of Advanced Mathematics, and that’s why he did this. low profile.”
"I asked for your opinion for this reason. When the time comes, it may have a little impact on you. If you find it troublesome, then reject him. If it is possible, I will Keep him!"
Wang Donglai nodded, knowing that Xu Songyao was telling the truth and not lying to himself, so he said aloud: "Uncle Xu, then stay, the mathematics department of our school really needs these people."
Xu Songyao laughed heartily and said: "Okay, with your words, then I can do it with confidence and boldness."
......
Time flies, and it's eight month.
The academic journal "Mathematics Future" of Tangdu Jiaotong University was officially launched.
The content of the first issue is Wang Donglai's "Proof Process and Ideas of Goldbach's Conjecture"
If it is an ordinary academic journal that has just been launched, if the number of subscriptions can exceed 10,000, it is considered to be a high-profile one.
Before the publication of Tangdu Jiaotong University's "Mathematical Future", many people in the academic world were secretly guessing how many subscriptions there would be.
Some people guessed it was ten thousand, some people guessed it was thirty thousand, and some people guessed it was fifty thousand.
The reason why they give such high guess data is because they believe that Goldbach’s guess is so powerful.
But they do not think that the number of subscriptions for "Mathematical Future" will be so high in the future. It will only get lower and lower, and finally reach the position where it should be.
Just when everyone in the mathematics community was having different thoughts, "The Future of Mathematics" was published.
The number of subscriptions exceeded 100,000 on the first day.
And this is just domestic.
University professors and scholars, private mathematicians, mathematics enthusiasts, students, etc. have all subscribed.
The journal was released. Scholars and professors in the field of mathematics at home and abroad finally saw the complete and detailed paper, and they all fell into detailed and in-depth research and verification.
However.
As the most important protagonist in this incident, Wang Donglai was busy with another thing.
That is the research and development of solid-state batteries!
With his magical abilities and skills, Wang Donglai has made rapid progress in research and development of solid-state batteries after such a long period of research and development.
However, the closer we look, the moment we are about to complete a breakthrough.
The real R&D conundrum of solid-state batteries arises.
Real solid-state batteries have various advantages, but equally, it becomes extremely difficult to improve the yield rate and reduce costs.
This is mainly due to the principle limitations of solid-state batteries.
Nowadays, lithium batteries are the mainstream. The structure is an electrolyte filled inside the battery. The electrolyte is a channel for lithium ions to move back and forth. The charging and discharging process of lithium ion batteries is the embedding and discharging of lithium ions. Deembedding process. During the intercalation and deintercalation process of lithium ions, the same amount of electrons as lithium ions are intercalated and deintercalated. During the charging and discharging process, lithium ions cycle back and forth between the positive and negative electrodes to be intercalated and deintercalated.
When the battery is charging, lithium ions are generated on the positive electrode, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon used as the negative electrode has a layered structure with many micropores. The lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer. The more lithium ions are embedded, the higher the charging capacity.
Solid-state batteries are different. The biggest difference from the current mainstream traditional lithium-ion batteries lies in the electrolyte. Solid-state batteries use solid electrolytes to replace the electrolytes and separators of traditional lithium-ion batteries.
Traditional lithium-ion batteries are mainly composed of positive and negative electrode materials, electrolytes and separators.
The positive and negative electrode materials determine the capacity of the battery, and the electrolyte and separator serve as the medium for transporting lithium ions.
Now, there are three schools of solid-state batteries on the market, namely oxide system, sulfide system and polymer system.
Oxide system solid-state batteries use a metal negative electrode and an electrolyte made of rare earth oxides, such as lanthanum.
No matter which one of these three schools, they all need to use rare earth elements, so the cost will be greatly increased.
The original physics problem also involves materials science.
The biggest feature of materials science is that it is uncontrollable and has too many variables. It takes time to conduct experiments one by one to know the best formula.
Wang Donglai’s research on solid-state batteries is stuck at this step.
