From university academician to chief academician

Three months later, it’s June!

In April, the first phase of the Latitude Blockchain Research Institute at Zhonghu University was completed, and half a month later, all the equipment was installed.

In early May, all researchers settled in the Latitude Blockchain Research Institute.

Starting from the beginning of May, Ye Fei spent a week each at Zhonghu University and the University of Electronic Science and Technology of China, flying back and forth between the two universities every weekend night.

Ye Fei sighed in his heart: "I don't have enough time. I wish I could have a clone, one at the University of Electronic Science and Technology of China and the other at Zhonghu University."

“This way we can take care of both sides.”

"It won't be like now, running back and forth from both sides!"

Of course, with such a busy life, the research progress of the two schools is also progressing at a gratifying level.

Ye Fei is a manager and only needs to provide research directions for his researchers.

Most of the work is done by my fellow researchers.

By June, five or six types of ultra-wideband pulses were discovered through Gaussian derivative functions.

However, in terms of performance, there is still a big gap with the world's advanced ultra-wideband pulse. It cannot achieve network speeds of 100GHz and is not suitable for Li-Fi.

The research on the application of asymmetric encryption algorithms is very gratifying. In just two months, half of the research has been completed, and in another two months, all the research can be completed.

At that time, the asymmetric encryption algorithm will be packaged and a blockchain system with the asymmetric encryption algorithm as the core will be developed.

This part is very simple and can be completed in one month.

By September, the new blockchain system can be released to the world for trial operation.

University of Electronic Science and Technology of China, in a certain laboratory!

Ye Feizheng was at his desk and quickly wrote the formula on the paper.

"No, it's still wrong!"

Many inspirations collided in Ye Fei's mind, trying to find the best pulse combination through mathematics.

Ye Feixin said: "Use the Gaussian derivative function to obtain waveforms that approach the radiation masking standard in all channels."

"The method is correct, but science is like finding a needle in a haystack. It is very difficult to find the best pulse combination."

Ye Fei's research method is like this. A group of people, led by Ye Fei, calculated a reasonable formula for the Gaussian derivative function.

Some people enter the formula into the pulse machine and look for pulses.

Another lab!

Yue Hongqing is a researcher doing research with Ye Fei.

When Ye Fei said that he wanted to completely make domestic products independent, Yue Hongqing was the first to stand up and support Ye Fei, and he was also the first to report to Ye Fei for research.

Yue Hongqing's image collapsed at this moment, with unkempt hair, pale face, and heavy dark circles under his eyes.

He is sitting in front of the pulse machine, conducting experiments again and again, hoping to find the best pulse from many wave bands.

He has been sitting here for three months, eating in front of the pulse machine.

Next to the pulse machine, there is an iron single bed. When Yue Hongqing is sleepy, he will go to the bed to sleep, and when he wakes up, he will continue to study.

In Yue Hongqing's view, only through continuous experiments can the best pulse be found.

Therefore, he used the Gaussian derivative function, combined with the pulse machine, and tried to find new ultra-wideband pulses through experiments over and over again.

Yue Hongqing was very sleepy at this moment, but he still kept his eyes wide open and refused to close them.

After a long time, there was a "Peng" sound, and Yue Hongqing hit his head on the pulse machine, just as the last number was input into the pulse machine.

He was so sleepy that he couldn't physically hold on.

At this time, an abnormal pulse waveform suddenly appeared on the pulse machine, which was instantly captured by the supercomputer in the background.

More than four hours later, Yue Hongqing woke up in a daze.

When he looked up at the pulse machine, he was stunned for a moment, and then his eyes widened in surprise.

"New ultra-wideband pulse?"

He tapped the keyboard quickly with excitement.

Then, he said excitedly: "So that's it. I said I've been looking for it for so long and still can't find it!"

"It is indeed possible to find new ultra-wideband pulses through Gaussian derivative functions. Professor Ye's method is right."

"It's just that we all entered into a misunderstanding before. We all thought that since the Gaussian derivative function is used, the energy density of the pulse must be affected by the pulse length and pulse integral."

"In fact, it is not the case. It is affected by pulse width and pulse differentiation."

"In many cases, the radiation shielding requirements outside the 5.1-20.3GHz range are difficult to meet with just a single pulse. The radiation shielding required by the FCC must be used with a single pulse waveform to meet the requirements."

"I want to tell Professor Ye and everyone else this good news."

After saying that, Yue Hongqing ran out quickly.

Soon, it became noisy outside.

"Professor Ye, someone discovered a new ultra-wideband pulse suitable for Li-Fi."

"What?" Ye Fei, who was doing mathematical calculations, raised his head in surprise, looked at the speaker and said, "Are you telling the truth?"

"it is true!"

Ye Fei stood up quickly and said, "Let's go take a look."

After saying that, Ye Fei walked outside.

After a while, a group of people gathered in front of a pulse machine.

A researcher was sitting in front of the pulse machine, typing on the keyboard quickly.

For a long time, groups of data were displayed on the computer screen.

The researcher turned to look at Ye Fei and said in surprise: "Professor Ye, this set of pulses is very good and fully meets the requirements of Li-Fi."

"Yeah!" Ye Fei nodded, looked at Yue Hongqing beside him, and said with a smile, "What's your name?"

There are thousands of researchers in the institute, and Ye Fei has only been here for a few months. It is impossible for him to know everyone's name.

Yue Hongqing was very excited at the moment. He said excitedly: "Professor Ye, my name is Yue Hongqing."

Ye Fei smiled and said: "Very good, very good, I will report your matter to the superiors."

The others looked at Yue Hongqing with envy. Considering the strategic significance of the Li-Fi experimental project in Xia State, as long as this matter was reported, Yue Hongqing would definitely receive a commendation from above.

Many people mutter in their minds: "Why don't I have such luck? How did Yue Hongqing find a new ultra-wideband pulse suitable for Li-Fi?"

Academician Ning's office!

Academician Ning looked at Ye Fei who walked in and laughed loudly: "Professor Ye, congratulations, I didn't expect you to find a new ultra-wideband pulse suitable for Li-Fi."

Ye Fei smiled and said: "Luck, luck, I didn't expect to find it."

"I initially tried to find ultra-wideband pulses using mathematical Gaussian derivatives."

"It is true that the Gaussian derivative function was used to find ultra-wideband pulses, but a researcher entered the wrong number, and then unexpectedly found a new ultra-wideband pulse suitable for Li-Fi."

"Haha..." Academician Ning laughed and said, "Science is like this. Sometimes if you look for it deliberately, you may not find it, but if you don't look for it deliberately, you will find it."

"Yeah!" Ye Fei nodded: "That's right. Science is really an interesting thing. It's full of mystery and makes people want to explore. No one knows what will happen in the next second."

"Perhaps world-changing technology can be discovered."

"Yes!" Academician Ning nodded: "This is also the reason why many people like to do research. Research can be addictive, and its happiness is no less than reading novels and movies and TV series."

"Yes!" Ye Fei smiled.

Academician Ning said: "Now that you have found a new ultra-wideband pulse suitable for Li-Fi, start the next step of research."

"Yeah!" Ye Fei nodded and said, "You tell me!"

Academician Ning said: "The next research is how to popularize Li-Fi. The shortcomings of Li-Fi are very obvious."

"1. There must be light!"

"Two, it can't pass through walls!"

"And the light of Li-Fi is visible light, which is also a disadvantage."

"Some people like to turn off the lights and surf the Internet. At this time, no visible light can appear."

"So, we have to solve two shortcomings of Li-Fi. One is that there is no visible light, and the other is that the Li-Fi wireless network can pass through the wall."

"We considered before that it couldn't be visible light, so it would only be infrared and ultraviolet."

"But they can't go through walls."

"And what goes through walls are radio waves, microwaves, X-rays and gamma rays."

"Radio waves and microwaves are invisible light."

"It conforms to the characteristics that it is neither visible light nor can pass through walls."

"But their network speeds are too low and are not suitable for Li-Fi, only Wi-Fi."

"Professor Ye, do you have any good ideas?"

Ye Fei frowned and said: "I don't have any good ideas at the moment. From all electromagnetic waves, only radio waves and microwaves are the most suitable, but the Internet speed is too low."

Whether it is visible light or invisible light, they are all electromagnetic waves, but the wavelengths are different.

"The Internet speed is high, but it is visible light and cannot penetrate walls."

"Those that can penetrate walls, two are invisible light, and the network speed is low, and the other two are visible light, but they cannot be used to study network speed."

What cannot be used to study network speed are X-rays and gamma rays.

When X-rays are exposed to the human body, they will destroy human white blood cells, causing hair loss, abnormal blood circulation, and tissue necrosis.

Gamma rays, also called Y-rays, are rays released when the energy level of an atom is deactivated. It has strong penetrating power and can kill cells. It is used medically to treat tumors.

It should not be irradiated on the body, otherwise it will kill cells and cause damage to the body.

If it is a gamma ray burst, it is the most terrifying thing in the universe. The energy released in one second far exceeds the total energy released by the sun in its lifetime.

Any planet in the universe will disappear in an instant if it is scanned, not even the dregs will be left.

Closer to home, from the current perspective of all electromagnetic waves, only radio waves and microwaves can be used as network transmission.

But their internet speed is too slow.

Ye Feidao: "Both the invisible light and the visible light of electromagnetic waves have serious shortcomings."

"Yes!" Academician Ning said: "So, we need to find an electromagnetic wave that has fast network speed, is invisible light, can pass through walls, and is not harmful to the human body."

Ye Fei nodded and said, "Yes."

Academicians Ye Fei and Ning were also confused and did not know whether such electromagnetic waves existed.

Of course, intellectually speaking, this kind of electromagnetic wave must exist, but it has not been discovered yet.

After all, everything is possible in science.

But intellectually speaking, maybe they can't discover this kind of electromagnetic wave.

Science has all possibilities, science can also make people addicted, but science can also make people despair.

This is like doing a math problem and you can't do it no matter what. The feeling of despair is very frustrating.

Zhonghu University, Latitude Blockchain Research Institute!

Ye Fei walked into his office and sat down, then called Shi Yao, the chief scientist of the institute.

Shi Yao is 32 years old. He has a doctorate in computer science and mathematics from Kyoto University. He mainly studies blockchain.

After the institute was first established, Kyoto University recommended Shi Yao to come here.

After Ye Fei personally tested Shi Yao's ability, he made him the chief scientist of the institute.

After Shi Yao came in and sat down, Ye Fei asked, "How's the research going?"

Shi Yao smiled and said: "In another week, the research on the asymmetric encryption algorithm will be completed. In a month, the blockchain system with the asymmetric encryption algorithm as the core can be created, and then it can be tested globally."

"Yes!" Ye Fei nodded with satisfaction: "There's no big problem here. Please help me keep an eye on it. I won't be here for the next month. I will come when the press conference is held."

Shi Yao asked: "What? Are you encountering difficulties in your research at the University of Electronic Science and Technology of China?"

"Hey..." Ye Fei shook his head and sighed: "We have indeed encountered difficulties. This is the first time I have encountered such a difficult research."

Ye Fei's previous research can all be solved through mathematics.

But Li-Fi research cannot be solved through mathematics alone.

Because Li-Fi research is not 100% related to science, imagination is even more important.

Shi Yao said with interest: "If it's convenient, can you tell me about it? I'm a computer major. Maybe I can provide you with some help."

Ye Feidao: "Okay, let's talk to you!"

"We are now looking for an electromagnetic wave that has high Internet speed, is invisible light, can pass through walls, and is harmless to the human body."

"Radio waves and microwaves can penetrate walls, are invisible light, and are harmless to the human body, but the only problem is that the network speed is too low."

"Infrared rays, visible light and ultraviolet rays have high network speed and are harmless to the human body, but they cannot penetrate walls."

"X-rays and gamma rays can pass through walls, but they are visible light and are harmful to the human body."

"So, all electromagnetic waves have their own drawbacks."

Shi Yao thought for a moment and then said: "In our computer field, many codes have their own advantages and disadvantages, but we can graft them together, just like different varieties of plants, taking out the advantages and removing the disadvantages."

"Do you think you can use this method to combine multiple electromagnetic waves?"

Ye Fei frowned and nodded: "This is a good method, but I don't know if it will succeed."

"After all, electromagnetic waves are a type of light that cannot be touched but are ubiquitous in nature."

"It's not a real object. If you want to combine light, no one can do it!"

"You are wrong." Shi Yao shook his head and said, "Photosynthesis was accomplished more than 20 years ago."

"There's not just photosynthesis, there's photoconversion."

"Dalian Institute of Physics once converted infrared light into sunlight."

Ye Fei said in surprise: "There is such a thing, but I am ignorant. It seems that I need to consult people in the physics world."

Shi Yao smiled and said: "You usually only focus on mathematics and computer research, you should also take a look at physics research."

"After all, mathematics and physics are not divided into different schools. Many mathematicians study physics and can easily get started."

"If you try to study physics, I believe you can easily get started."

"I will." Ye Fei smiled.

After returning to the University of Electronic Science and Technology of China, Ye Fei found Academician Ning and said, "Academician Ning, I have thought of a way to combine multiple electromagnetic waves."

"Photosynthesis?" Academician Ning said, "Yes, we can synthesize electromagnetic waves."

"Since every electromagnetic wave has shortcomings, we can take out the advantages of multiple electromagnetic waves and synthesize a brand new electromagnetic wave."

"Such electromagnetic waves must have high Internet speed, are invisible to visible light, can pass through walls, and are harmless to the human body."

"Yes!" Ye Feidao: "We are not good at this. I suggest consulting physicists, they are good at this."

"Okay!" Academician Ning said, "I know many physicists, and I will call them immediately to consult them."

After saying that, Academician Ning took out his cell phone and made a call.

Over the next month, Academician Ning called in a number of physicists to consult with them about synthesizing light.

Ye Fei also benefited a lot and became very interested in physics.

"It turns out physics is so interesting!" Ye Feixin said, "I must study physics if I have the chance."

Ye Fei discovered that physics is different from mathematics.

Although mathematics is the basis of physics, physics can create various technologies.

Almost 90% of the things around modern humans are made of physics.

It can be as small as a screw, as large as an airplane, or as large as a satellite.

Ye Feixin said: "It's great to solve mathematical problems, but it's also great to create technologies that benefit the world."

It is now September, and the blockchain system created by the Latitude Blockchain Research Institute of Zhonghu University is about to be released to the world.
