Great Country Academician

Jinling.

Xia Shu Space Base.

In Academician Chang Huaxiang's office, the phone number from Xinghai Research Institute has already been called.

"Academician Xu, are there any specific criteria for selecting three ordinary people and sending them to travel to the moon?"

On the other side of the phone, Wen Yuanhang, who is responsible for the daily work management of the institute, asked.

Xu Chuan's sudden idea to win three places to travel to the moon from the CTV live broadcast room really confused him.

When the external customer service lady reported that she had received countless calls from people to inquire about this matter, he was stunned for a while.

But thinking back on it, it seems to be quite in line with this person's character. He comes up with ideas as soon as he comes up with them, and his action ability is quite strong.

Xu Chuan smiled and said: "Just follow the standards of the space travel business. There will be no problem. We have conducted voyages between the earth and the moon countless times, and we have maintained zero accidents so far."

Wen Yuanhang smiled and said: "I'm not worried about this, I'm just worried."

After being stunned for a moment, he suddenly remembered that there seemed to be nothing to worry about.

Are you worried that ordinary people's bodies will withstand the low gravity environment of lunar travel? It doesn't seem necessary.

After all, Xinghai Research Institute has already had space travel business, but it is basically for the rich.

A space trip costs 19.99 million meters per trip. Even a rich man cannot afford this amount.

Now we just shift the target from the rich to ordinary people. Apart from a little less income, there is not much difference.

"What are you worried about?" Xu Chuan asked curiously.

"It's nothing." After coming back to his senses, Wen Yuanhang said with a smile: "Then I will process the three pictures you sent before in the order of the screenshot list."

Xu Chuan smiled and said: "Just handle it this way. I'm sorry to bother you."

"No trouble, it's just my job." Wen Yuanhang smiled and said, "By the way, Academician Xu, I have one more thing to ask."

"Regarding these three tickets for a trip to the moon, if the chosen people want to sell them, is that allowed?"

Hearing this question, Xu Chuan was stunned for a moment, thought for a while and then said: "Allow it, provided that the selected people are voluntary."

"As for the person being traded, just do a background check to avoid being mixed in with someone like him."

A ticket to travel to the moon, according to the current price they have set for space travel projects on the market, is as high as nearly 50 million yuan. According to the current exchange rate, that is 200 million RMB, two small goals.

For ordinary people, this can be said to be a fortune that cannot be earned in a lifetime.

Although it is impossible to sell this kind of resale travel voyage at this price, even if it is only half or even one-third, it is still a huge sum of money for ordinary people.

There is no need to fix the lottery quota so that it can only be used by the lottery winner.

This kind of temporary lottery does not require much money for Xinghai Research Institute.

But it can greatly enhance the reputation of Xinghai Research Institute, which is quite worth it.

Wen Yuanhang nodded and said, "Okay, after I finish processing the plan, I will send it to you for a look."

"good."

After hanging up the phone, Xu Chuan stuffed his phone into his pocket.

Opposite the sofa, Academician Chang Huaxiang looked over and asked with a smile: "You came up with this, could it be that you wanted to follow it?"

He really wasn't just talking about this, he had a criminal record. The last time some princes from the Middle East came here to discuss cooperation, this man went into space with them.

This time, three ordinary tourists were selected for the live broadcast room of CTV Central, so maybe they are trying this idea again.

Hearing this, Xu Chuan was stunned for a moment, touched his chin and said, "I really didn't think of this if you didn't tell me."

Drawing three places in the live broadcast room was indeed his sudden idea at the time, and he never thought more deeply that he could go to the moon with him.

Opposite me, Chang Huaxiang smiled bitterly and said, "You really don't want to take this opportunity to go to the moon together, do you?"

Why did he feel like he had accidentally awakened Xu Chuan? If this person really went to the moon with the traveling team, the senior management would probably be worried to death.

Xu Chuan thought for a while, shook his head and said, "I won't go this time, maybe next time. I have some other things to deal with this time, so I probably won't be able to make it in time."

Hearing this answer, Academician Chang Lao breathed a sigh of relief and said with a smile: "You, you should pay attention to safety issues. You can go to the moon at any time, but now you are not even married."

It would be better to talk to the higher-ups about this matter. If this person can't talk about it now, he might get a big headache if he sneaks up with him later.

However, he did not continue the conversation on this topic, and instead smiled and said: "Speaking of which, I also know a few girls of the granddaughter level here, some are about the same age as you, and some are a few years younger. I introduced them to Do you know him?"

Hearing this, Xu Chuan, who was drinking from a tea cup, almost spit out a mouthful of hot tea.

After swallowing the tea in his mouth, he smiled helplessly and said, "Why did you start, Mr. Chang?"

The topic of urging marriage has been heard more and more in his ears as his age has begun to approach thirty in the past two years.

Chang Huaxiang said cheerfully: "You are not young anymore. You are twenty-seven this year. There is a saying that after thirty, there will be no offspring. You can get married at the age of twenty-seven. Even if you don't get married, you can decide it early. OK."

"I think back in our day, people were getting married and having children at the age of twenty. They were everywhere. How could they wait until they were in their twenties, eighties, or thirties?"

"Let go of our time"

Hearing these words, Xu Chuan quickly interrupted: "Stop, stop, stop."

"Chang Lao, times are different now. Getting married at the age of thirty is nothing."

Chang Huaxiang shook his head helplessly and said, "You, forget it, you can't force marriage."

There's really no way to force this kind of thing.

This era is no longer the era where they knew the orders of their parents and the words of matchmakers.

These days, if the parties involved do not agree, it will be useless even if they move the Civil Affairs Bureau.

The Fuyao space shuttle officially launched carrying a large amount of Mars exploration equipment.

A brand new major mission is ushered in at the Xiashu Space Base.

Xu Chuan did not stay here. After the Fuyao took off, he left here and returned to Xinghai Research Institute.

It will take more than a month for the space shuttle to reach the orbit of Mars. Such a long time is enough for him to do other things.

Sitting in the Hongqi car, Xu Chuan was scrolling through messages on his phone. At this moment, Weixin's video call rang. It was the girl Xu Xiao.

"Hey, Xiaoxiao."

With a smile on his face, he slid his thumb across the screen and answered the call. On the opposite side, a familiar face came into view.

"Brother! Help me!"

During the video call, Xu Xiao said with a sad look on his face.

Seeing her gloomy look, Xu Chuan couldn't help but smile and asked curiously: "What's wrong? Why are you looking so gloomy?"

"Research on brain-computer interfaces."

Xu Xiao puffed up his cheeks, took a long breath and then continued: "There is a problem with the research work on brain-computer interface. It may be necessary to re-model the overall mathematical model."

Xu Chuan asked curiously: "Modeling? I remember didn't I get this done for you last time?"

Xu Xiao nodded and said, "Brother, do you still remember that I published a paper in Science magazine when I was a graduate student at Shuimu University?"

"There is a paper on the method of implanting electrodes in monkey brains to form a certain vision without passing through the retina."

Xu Chuan thought about it for a moment, nodded and said, "Remember, what's the matter?"

Xu Xiao quickly said: "The mathematical model of that method was completed by Sister Jiaxin and I. The mathematical model reset for the array composed of multi-electrodes can greatly stabilize the stability of the brain electrical signal and the accuracy of the artificial image. resolution.”

“But it may conflict with the mathematical model you established before, ‘Research Theory of Simulating Nerve Signals and Electrical Signal Conversion Based on Quantum Theory’.”

"When the two sets of mathematical tools are converted, it will incorrectly distort the transmission of neural signals."

"To put it simply, when these two sets of mathematical models are used to input and output the nervous system, one original instruction will be reversed into another instruction, or amplified and reduced, in the human nervous system."

"As you know, the human body's nerve signal transmission itself is a very complex task. If it is missed by a tiny bit or a thousand miles, even if it is reduced or enlarged, it will cause problems in the body's execution of commands."

Hearing these words, Xu Chuan frowned slightly and asked, "Didn't you find this problem before?"

The research theory of simulating neural signals and electrical signal conversion based on quantum theory was something he wrote personally during the Chinese New Year the year before last.

Although there is no research in the field of brain-computer interface, he must have seen the mathematical model for resetting an array composed of multi-electrodes that Xu Xiao previously developed.

For this level of mathematical model, the underlying mathematical logic is nothing to him.

Logically speaking, the theory he completed should be in good agreement with the former, and this kind of problem would not arise.

But since Xu Xiao said that this kind of problem occurred, it must be that something unexpected happened between these two areas.

Xu Xiao shook his head and said: "This is only known after entering the clinical trial stage and receiving feedback from patients in the trial."

"In the past, we conducted experiments on animals such as mice and rhesus monkeys. These animals certainly cannot fully feedback their feelings to us like humans."

Xu Chuan thought for a while and said, "Where are you conducting experiments now?"

Xu Xiao: "Hexi Campus of Jinling First Hospital."

Xu Chuan: "Okay, I'll go over and have a look. Also, please send me the experimental data first."

"Okay, I'll sort it out and send it over right away."

After hanging up the video call, Xu Chuan leaned forward and said, "Let's not go back to the institute now. Let's go to the Hexi Campus of Jinling First Hospital."

Zheng Hai nodded: "Okay."

The car was driving on the road, turned a corner, and drove along Qixia Avenue along the river towards the Hexi Campus of Jinling First Hospital.

In the back seat, Xu Chuan took out a three-fold screen mobile phone from the storage box in the middle of the seat.

This was given to him personally by Mr. Ren from Warwick. It seems to be the latest model released in September last year.

In terms of price, it seems that a regular one costs 20,000 to 30,000, but he is not very clear about the details.

The one he has is specially customized by Warwick. The three-fold screen is 12.9 inches when opened, which is the size of a large tablet.

However, after folding, it is not much different from the max version of a normal mobile phone, and the technology is still quite powerful.

In addition, it is equipped with various commonly used office parts such as writing pens, small keyboards, card holders, etc.

In daily life, Xu Chuan did not use this mobile phone. He basically left it in the car and used it to temporarily handle some things during travel, which was quite convenient.

The mobile phone with a three-fold screen was unfolded and used as a temporary office computer. The email from Xu Xiao had been sent.

After downloading the experimental data in the email, Xu Chuan opened it and read it bit by bit.

Although he had not studied brain-computer interface technology, it was the defense line for recommending Xu Xiao to study and research, and he had been paying attention to his sister's research in recent years.

Now he knows a lot about this aspect.

The concept of brain-computer interface was actually proposed very early. When the computer was just a device, someone proposed a related theory.

Refers to the technology of creating a direct connection between the human or animal brain and external devices to achieve information exchange between the brain and computer devices.

Its mechanism of action is to bypass peripheral nerves and muscles and directly establish a new communication and control channel between the brain and external devices.

It achieves information transmission and control by capturing brain signals and converting them into electrical signals.

But it was not until the 1990s that phased results began to appear.

For example, mind-controlled toys, mind-controlled robotic arms, mind-controlled wheelchairs, etc.

Among them, the most famous is Hawking's wheelchair.

His wheelchair is not only a means of transportation, but also an intelligent device that integrates a variety of high-tech devices.

Since 1963, Hawking's wheelchair has undergone at least five important upgrades, adding a variety of functions.

For example, intelligent finger controllers, text-to-speech processors, infrared monitoring of facial muscle activity to control computer technology, eye tracking technology, brain-computer interface technology, etc.

This not only allows him to live a normal life, but also allows him to work, research and communicate like a normal person.

Of course, this wheelchair is specially customized. If the funds spent on various technical upgrades are counted, it is worth at least tens of millions.

In short, even if this kind of customized technology can be done, it does not have much commercial value, not to mention that its brain-computer interface technology is not very mature.

After all, the signal-to-noise ratio of the human brain is extremely low, and the characteristics of different human brain signals vary greatly, which makes it difficult for traditional signal processing algorithms to achieve ideal results.

One of the main technical difficulties of brain-computer interface technology is "how to achieve high-precision signal acquisition and recognition."

Simply put, the brain waves and brain nerve signals generated by each person's brain are completely different.

Special customization is meaningless. Only by establishing a relatively universal conversion and processing system for this purpose can it have real promotion and commercial value.

Part of the problem that Xu Xiao just talked to him about is here.

As for the other part, it is about the connection and conversion between two different systems.
