Chapter 283 The unexpected gains of the Riemann Hypothesis
“Why, do you know?”
Cai Wensheng asked Xu Qingshan with curiosity in his voice.
He was a little surprised. Xu Qingshan's voice was not loud, but something strange could be heard in his tone.
“This black rice is named after someone else’s apple, right?”
Xu Qingshan suddenly asked.
Cai Wensheng was silent for a moment.
“Ahem, just kidding, aren’t there some mango phones and big pineapple phones on the market?”
“The United States has Apple, China has pineapple!”
< br>Xu Qingshan also imitated the startup sound.
"What's going on?"
Cai Wensheng couldn't help but laugh out loud, but his attention was also diverted.
"Brother, please tell me carefully. If it is like the pineapple phone, I don't think the profit is high?"
Xu Qingshan asked knowingly.
“That’s right.”
Cai Wensheng said.
“I don’t know if you know Lei Jun. Lei Jun was recruited to Jinshan by Qiu Bojun, but later he failed to run Joyo.com.”
“Yes, he didn’t go to Meizu to follow Have you made a mobile phone? The mobile phone I am using now is a Meizu smartphone."
Xu Qingshan said with a smile.
"Yes, but he and Huang Zhang didn't reach an agreement and broke up. Now he has a team and wants to start his own business. He will go out again and make mobile phones by himself. Just a few days ago, about 1 On the 3rd of March, I made an appointment with Tong Shihao from Qiming Venture Partners to meet at Pangu Seven Stars Building. On the 5th, I made an appointment with Liu Qin from Morningstar Capital. He called me the day before yesterday and asked me to go to Beijing next week for a detailed discussion. I just mentioned it to him. You, he is very interested in you and wants to meet you. I wonder if you have any ideas.”
Cai Wensheng explained the origin of the matter clearly, and Xu Qingshan suddenly realized it.
In fact, he also wanted to use Cai Wensheng to get to know Lei Jun, but Lei Jun took the initiative to come to him this time. If he knew him because of his achievements in scientific research, then it would be better to come to Beijing directly.
What passed was Cai Wensheng's line, and it was probably the only possibility that Cai Wensheng said.
“Of course, I also want to get to know Mr. Lei.”
Xu Qingshan said calmly.
If there is an opportunity to talk about the entrepreneurs he most wants to contact, Lei Jun will definitely be at the top.
Not because of anything else, but mainly because Xu Qingshan wanted to see with his own eyes whether Lei Jun really only had Kali's cold 4 billion when he was at his lowest.
"That's easy. Then when I arrive in the capital, you can go with me to meet him."
Cai Wensheng smiled happily.
As a kind of big brother in the world, he likes to facilitate meetings between friends.
The meaning of the meeting between Xu Qingshan and Lei Jun is even more different.
In the business world, Xu Qingshan at least has Cai Wensheng's mark to some extent, whether it is the car Xu Qingshan drives now or some of the capital's resources that Xu Qingshan uses.
Even Wang Chuan, who is now Xu Qingshan's anqianmahou.
These are the obvious marks of Cai Wensheng.
It’s just that Xu Qingshan doesn’t shy away from these things. He and Cai Wensheng didn’t meet too many times, but Cai Wensheng was very helpful in starting his career.
And Lei Jun, in the current Internet arena, can be regarded as a big brother-like figure.
Although his current size is not as big as later.
But his name is now in the Internet entrepreneurial circle, which is a reputation. As long as he launches it, many people will definitely respond and be willing to invest their own money.
At least every time Lei Jun starts a business.
In the first round of financing, a lot of brothers came to him with just one phone call, either they had done business with him before, or they had invested in him when he was an angel investor before.
But no matter what, in the non-company operations, Lei Jun is always easy for people to feel his charm and recognize him.
In Xu Qingshan’s view, this is a kind of leadership.
Some people come out to be the big brother as soon as they debut.
After hanging up the phone.
Xu Qingshan was sitting at his desk, his long, white fingers pulsing on the desk. He was thinking about what he would talk about and what would happen when he met Lei Jun.
Seeing that he was deep in thought, Wang Wei didn't have the nerve to disturb him, so she had to wait for Xu Qingshan to come to his senses and start playing with the small potted cactus made by Jiang Huanxi on the table. Then she carefully took her information documents and moved them to the table. Xu Qingshan is in front of the table.
"Teacher"
"Huh? Xiao Wang, what can I do?"
Xu Qingshan motioned to Wang Wei that you are welcome, just sit down and chat.
There are only two of them in the office of the Institute of Mathematics, and there are no outsiders. They have something to talk about. They have obviously been working together for a long time, so why are they still so reserved?
"Teacher, this is the main issue, I think."
Wang Wei took a thick stack of materials and flipped through them page by page. Almost every few pages there would be something she marked with her own red pen. Some questions.
In fact, Wang Wei's interpretation of documentary materials is very good, and Xu Qingshan can also see that her foundation is very solid.
And judging from her thinking and extending to problems, her research sense is not bad either.
It’s just that this part of the work didn’t seem to be assigned to her by herself.
Xu Qingshan didn't pay much attention. He just told Wang Wei one question after another.
Wang Wei kept nodding his head, like a pile driver.
After a long time, the speed was much faster than Wang Wei expected, and Xu Qingshan finished explaining these problems to her.
"Teacher, you are really powerful."
Wang Wei's reflex arc was not that slow this time, or maybe she had been accumulating strength for a long time before she could stand upright with her long black hair and face. He gave Xu Qingshan a thumbs up with a slightly paralyzed expression.
"Okay, let's go play by ourselves."
Xu Qingshan smiled politely, waved his hand, and let her study by herself.
Nothing more.
At this time, after having solved the students' problems in a targeted manner, Xu Qingshan was free again and planned to start thinking about his basic ideas about the Riemann Hypothesis.
But he suddenly raised his eyebrows.
"Xiao Wang, bring me the information just now and show it to me."
"Oh, okay."
Wang Wei is like a little goose, he just sat down, Before he could warm up his chair, he sat down at Xu Qingshan's table again.
“Let me take a look.”
Xu Qingshan took over the stack of documents again.
But this time he did not read page by page like he did just now, but shuffled these documents according to his memory when he gave Wang Wei the answer, and then spread them all out on the table.
His eyes were as sharp as a falcon, scanning these documents as quickly as a scanner.
At the same time, Xu Qingshan also asked Wang Wei.
"Xiao Wang, what did you use this information for?"
Wang Wei was stunned and hesitated.
"I just thought that the teacher had made a breakthrough on the twin prime conjecture, and the next step would be to do the Riemann Hypothesis, so I wanted to do some basic homework in advance, so that when the teacher needs to hire people, I wouldn't be able to keep up. "
Wang Wei said honestly.
She cherishes the opportunity before her. Because as an outstanding student of Peking University, she knew very well that her research limit at Peking University was almost locked. However, at this time, as a girl, her family did not support her going abroad.
At home, in her opinion, Xu Qingshan in front of her is her only chance to touch the forefront of the world and the field that interests her.
She also knew that her reflex arc was much slower than Xiao Xue's adaptability.
Since there is no way to win the teacher's attention through cleverness, she must work hard and prepare plans.
“Not bad.”
Xu Qingshan nodded.
Although he was chatting with Wang Wei, his hands were not idle.
Xu Qingshan quickly rearranged the documents on the table. Some documents were stacked together and placed in one place. Some documents were placed in one place, and some places were obviously free for additional documents. .
But this desk still seems a bit small.
Xu Qingshan simply took a box of magnetic stones and walked to the blackboard nearby, trying to attract these documents to the blackboard.
It's just that one document is okay. Once there are too many stacks, the force of the magnetic stone is not enough. And after trying it for a while, the blackboard is not big enough.
“Go to the window.”
Xu Qingshan thought for a while and looked around.
Just move your chair away and place the documents in the spacious space inside.
Wang Wei quickly followed Xu Qingshan and helped him, but she didn't know what Xu Qingshan was going to do.
But for those who study mathematics, it is normal to get nervous from time to time.
Wang Wei felt that this was normal for Xu Qingshan.
"Xiao Wang, do you have any other information on the Riemann Hypothesis?"
Xu Qingshan asked.
“Yes, I have prepared the more important information on the Riemann Hypothesis over the years, and I have printed it out and kept it, but I am familiar with that part first.”
“ Okay, bring them all to my table."
Xu Qingshan waved his hand.
He continued to sort out the documents on the ground, then found a few pieces of chalk from the side and started scribbling directly on the floor.
Wang Wei poked his head a little to see what Xu Qingshan was doing.
But I saw Xu Qingshan painting a tree.
But it is not accurate to say that it is a tree. To be precise, it is like a spindle-shaped tree-shaped mind map.
It’s just that not all the lines lead back to another end point in the end, but spread out, that’s why it is said to look like a tree.
"Hmm"
"Hua la la la."
Xu Qingshan stood at the table, looking at the vein lines he had sorted out on the ground, and specific details were constantly emerging in his head based on the vein lines. The content of the literature comes.
At the same time, he was flipping through the literature on the table with one hand.
Xu Qingshan kept watching while placing each piece of information he had read in the position he had preset.
"Little Wang."
"Hey, I'm here, teacher."
Wang Wei, who had become idle after Xu Qingshan started to fall into strange operations, has been waiting for Xu Qingshan's call. .
Otherwise she always feels like she has no sense of participation.
“Come on, I will write down a few key categories here. You can look at the keywords of these papers and put them into the corresponding categories. If there are multiple keywords involved in a paper, then Just put it in this multiplex area, do you understand?”
Xu Qingshan did not let her stand and watch when he accepted people.
He wants to sort out a relatively complete clue to solve the Riemann Hypothesis for himself.
The questions and ideas given by Wang Wei just now gave him a moment of enlightenment, but he also clearly realized that the work Wang Wei had done was not the answer to the real Riemann Hypothesis. It's just a borderline.
If you want to truly find the entrance to solving the Riemann Hypothesis, you must understand all the details.
This operation of integrating and summarizing information is not easy.
Because even though all the documents here have been included in the thesis database, it seems to have certification and endorsement from the academic community, but in fact, Xu Qingshan must constantly simulate, deduce, and screen to remove those that may be harmful to what he is looking for. The really correct thinking has a misleading direction.
This process is quite brain-burning.
When Wang Wei, who was a little busy next to him, secretly looked at Xu Qingshan, he noticed that his head seemed to be steaming, and there were dense beads of sweat on his forehead and neck. This made Wang Wei see I was stunned for a moment.
After all, this is a heated room.
Even if the door is not closed, some of the wind blowing from the corridor will still be swept into the house.
Maybe Qingshan’s head seems too hot now?
"Old teacher, let me wipe your sweat."
Wang Wei quickly took out a tissue and came over to wipe Xu Qingshan's sweat. Xu Qingshan waved his hand.
"You move faster and keep up with my rhythm. Just put the tissue behind my collar."
Xu Qingshan was still immersed in the process of sorting out his thoughts.
This was also the first time that Wang Wei saw a top mathematician solving problems live in front of her, even if the operation was only at the level of ideas.
But even so, Wang Wei felt that the tall young scholar in front of him was filled with golden light.
The golden Buddha statue was even more eye-catching than when she went to worship Buddha in the mountains when she was a child.
“This one won’t work, and this one won’t work either.”
“Well, this is misleading, but it has some reference, so let’s put it here.”
"What kind of shit is this? Journal of Mechanical Mathematics? Why would someone send a pure mathematics paper to a place like this?"
Xu Qingshan was mumbling something, and he looked very distracted.
And after thinking about the documents he felt were useless, he would throw them behind him, and Wang Wei quickly followed behind him to pick them up.
"Well, in this case, it should be about the same."
Xu Qingshan looked at the thread of thoughts on the ground in front of him, stroked his chin, and thought about where many of the vacancies should be. What kind of literature are you looking for?
And after summarizing the current ideas, if I want to get closer to the Riemann Hypothesis, I need to find a breakthrough somewhere.
“Xiao Wang!”
The more passionate Xu Qingshan is, the louder his voice becomes.
“Arrived!”
Facts have proved that if someone shouts loudly suddenly, you will subconsciously answer.
"Now, turn on the computer and start searching. I need to read all the information about visualizing the Riemann function. The ones just now are not enough, so I will add some more."
"I will also look for more information on the analytical continuation operation, as long as it is relevant Pick them all out and show them to me."
"And."
Xu Qingshan turned his back to Wang Wei and gave orders. The girl behind her was almost smoking with her hands. .
However, Wang Wei is also beginning to enter the state.
"What are you..."
A weak voice came from the door.
