Ye Fei first flew home and spent the Spring Festival.

After staying at home for about half a month, on February 15, he returned to Zhonghu University.

After returning to Zhonghu University, he went to see the people in the number theory group for the first time.

Although the school is now on vacation, there are still many students and teachers who stay in school because of scientific research.

Soon, he walked into the office of the number theory group.

During his research at the Information Resources Research Center of Chang'an University of Electronic Technology, he came back every six months to check on the research progress of his fellow researchers and guide future research directions.

In general, the number theory group led by Amata, and although the speed of research is not comparable to that of his time, it is also advancing at a visible speed.

Number Theory Group!

Ye Fei finished reading the research of his team members in the past half month, and nodded with satisfaction: "It's not bad, the research on the mold form has been completed by a quarter." ”

In his absence, he spent two months researching a quarter of the mold.

It's four times slower than when he was there, but it's good.

After all, he is a hanging person, and they cannot be compared with themselves.

Ye Fei looked at Amata and said, "Amata, thank you for your hard work." ”

Armatta shook his head regretfully and said, "If you were here, the research might have been completed by now, and in your absence, the speed of our research is too slow." ”

Actually, this speed is not slow, when he used to do research at Cambridge University, it was even slower than that.

But people can't enjoy it, and when you enjoy faster research, you don't want to experience the speed of research in the past.

It is easy to go from thrift to luxury, and it is difficult to go from luxury to thrift!

Ye Fei smiled and didn't speak.

He looked at the team members and said, "Everyone is doing very well, and when the mold form is studied, I will recommend some projects to you according to the ability of each of you, and you can work together with several people." ”

"Of course, if I have time, I can also take you to do projects."

Except for Amata, the rest of the people heard this, and their eyes lit up.

Last time, Ye Fei took them to do a project, and they made a lot of money, which made them taste the sweetness.

Ye Fei said: "Okay, let's talk about the following research directions. ”

With that, he picked up his pen and wrote down some formulas on the whiteboard.

【(q)=qπ(1-q)^24=……】

He put down the pen in his hand, pointed to the whiteboard again, and said, "The next thing you will study is this, whether the coefficients can be calculated in polynomial time." ”

"This research involves algebraic number fields, function fields, elliptic curves, and modular symbols."

"If you have questions, you can ask them now."

More than an hour later, Ye Fei walked out of the office and walked towards the laser laboratory.

At this time, the laser lab is busy.

Ye Fei felt that something was wrong as soon as he entered the laboratory, and everyone's expressions looked very laser.

He wondered in his heart: "Is it because the experiment is in the final stage, so everyone is excited?" ”

"It should be."

With that, he walked into the room where his group was.

Everyone looked at Ye Fei and said excitedly: "Team leader, you're back." ”

Ye Fei smiled: "How's the work going?" ”

Ban Chaolin was the first to say: "Team leader, we have carried out data docking with other teams, and the work is perfect, and there are no problems. ”

"Hmm!" Ye Fei nodded.

The hardest part of the experiment has been done, and only the easiest part remains.

If they can't even do something as simple as data docking, they can get out.

Ye Feidao: "Tell me, after the data docking, what is the effect of the ground-based anti-satellite laser weapon?" ”

Although the real thing has not yet been made, the theoretical part, after the data docking, it is already possible to know what the effect of the real thing is.

Everyone's expressions were instantly excited, and everyone was talking nonsense, but Ye Fei didn't hear a word clearly.

He pointed to Yu He Da and said, "Yu He Da, you can talk about it." ”

Everyone quickly stopped, and Yu He Da said happily: "Team leader, after the data docking, the ground-based anti-satellite laser weapon has a very good effect. ”

"Ground-based anti-satellite laser weapons are paired with the Kyoto-3 satellite, which can be observed in any picture of the world."

Kyoto-3 is the best observation satellite in the summer country.

It is also one of the best observation satellites in the world.

It can observe any city on Earth, photographed from an orbit of 500 kilometers, with a resolution of 50 centimeters per pixel.

You can even see the license plate number of the car on the road.

"This also makes the attack range of ground-based anti-satellite laser weapons very large, and everything that can be observed is its attack range."

"So big?" Ye Fei was surprised.

Although he participated in the experiment, he only did the theory of the mathematical part, and he did not have a clear idea of what the weapon would look like.

"Not only that, but it's the fastest attack speed, team leader, guess what?"

People like He Da are all playing playful at this time.

It's really a weapon that works so well.

Ye Fei asked tentatively: "Mach 40,000?" ”

Mach 1 = 1225.08 km/h.

The reason why Ye Fei said Mach 40,000 is because the laser itself is very fast, equivalent to the speed of light.

This is equivalent to Mach 44,079 in one hour.

However, this is only theoretical, and the actual creation will never reach this speed.

But Mach 40,000 should be achievable.

"Uh......" Yu He Da smiled bitterly: "Team leader, what you said is too conservative, you can expand your ideas a little more." ”

He didn't wait for Ye Fei to speak, so he said excitedly: "It's Mach 400,000, the base anti-satellite laser weapon, the speed reaches Mach 400,000, which is very close to the speed of light." ”

"How much?" Ye Fei's eyes widened in shock: "Mach 400,000, you're not wrong?" ”

"Team Leader!" Ban Chaolin said: "Yu He Da is not wrong, it is Mach 400,000. ”

Ye Fei gasped, he didn't expect that the weapons they made were so awesome.

Yu He Dadao: "Professor Kong said that our mathematical theory group plays the most crucial role in it. ”

"Originally, the effect would not be so good, but because the formula of our mathematical theory is so perfect, every piece of data is very accurate, and there is not a single nanometer error."

"Because the data is perfect, the weapons created can attack at a speed very close to the speed of light."

"Many countries in the world have laser weapons, but none of them have laser weapons that reach Mach 400,000, and even Mach 300,000 are very few."

"And the laser weapons we make are the fastest laser weapons in the world."

Ye Fei asked, "How about the power?" ”

Yu He Dadao: "According to the model simulated by the supercomputer after the data docking, the power reaches 400 billion watts. ”

"Four quadrillion watts?" Ye Fei exclaimed: "Is it so high? ”

Yu He Dadao: "It's really so high. ”

Ye Fei was dumbfounded, and said after a while: "......"

The highest power of laser weapons in the world is one gigawatt, and even so, this power can destroy an aircraft carrier with a single blow.

And this weapon is the LLD, a high-energy laser weapon in the North of the United States.

Ye Feidao: "The attack range covers the whole world, with a speed of Mach 400,000 and an attack power of 400 trillion watts. ”

"This is perfect, this is equivalent to the level of a nuclear weapon!"

Yu Heda shook his head and said: "Team leader, there is still a certain gap between it and nuclear weapons, and it has several fatal shortcomings. ”

"What are the drawbacks?"

"The charging time is very long, and you only have the ability to hit one hit for a short time, and the next time you attack, it will take a few weeks to recharge."

"And, it's a lot of satellite consumption."

"Satellite-draining?" Ye Fei was puzzled: "What do you mean?" ”

"When the weapon is launched, it will produce a strong reaction force, and the ground-based anti-satellite laser weapon we have developed will produce a strong reaction force at the moment of attack, and it will have a certain loss of the satellite."

"After every attack, people have to be sent up to repair the satellites."

"Also, the scope of its destruction is very small, it is not like a nuclear weapon, the scope of destruction is very large, its range of destruction is only about 700 acres."

"The range of destruction equivalent to the size of an aircraft carrier."

"Hey......" Nanjing Shan shook his head and said regretfully: "It's a pity that such a powerful weapon has these three fatal shortcomings." ”

The rest of the people also regret it in their hearts.

The energy storage time is long, and several more can be made.

But it is harmful to satellites, and it takes a lot of money to manufacture a satellite, and no country can put thousands of satellites in the sky.

Even the Northern Beauty, which has the most satellites, has only more than a thousand satellites in the sky.

So, every time a ground-based anti-satellite laser weapon is launched, it is not an attack, but a burning of money.

Also, the destruction range is small.

Even if it is powerful and fast, the small range of destruction greatly reduces the deterrent power of ground-based anti-satellite weapons.

Ye Feidao: "It's normal, these are common problems of ground-based anti-satellite laser weapons, and it is difficult to change them." ”

He thought for a moment and said, "Don't talk about this, where is the work going now?" When did the physical object start to be manufactured? ”

Yu He Dadao: "The data docking can be completed in another month, and then the weapons will be manufactured." ”

Ye Fei said: "Okay, I know, you can continue, I'll go to other groups to have a look." ”

With that, he walked outside with his hands behind his back.

He entered the room where Professor Yuan Hua's group was located, and saw Professor Yuan Hua sitting in front of the computer, inputting data into the computer one by one according to the content on the paper next to him.

He walked up to Professor Yuan Hua and said with a smile: "Professor Yuan, you're busy!" ”

"Go away, don't bother me." Professor Yuan didn't raise his head.

"I, Professor Yuan, am me, Ye Fei."

Professor Yuan turned his head to look at Ye Fei and said with a smile, "When did you come back?" I'm sorry, I just didn't know it was you. ”

"It's fine!" Ye Fei smiled: "I just came back too, how is it?" Is your group still working well? ”

"Haha......" Professor Yuan laughed and said, "With the help of your theory group, the work of our application group is very smooth. ”

As he spoke, he stood up, pulled Ye Fei to find a place to sit down, and said excitedly: "The formula you made is really good, your team studied according to your formula, and the data was perfect, and our application team also did a perfect job according to your theory." ”

"The theoretical physics group and the applied physics group, because of our mathematical support, the experiments went very smoothly."

"It went well beyond our expectations."

"Ye Fei, this is all your credit, if it weren't for your perfect formula, our experiment would not have achieved such a perfect effect."

"You should have heard about the weapons simulated by supercomputing after data docking!"

"Hmm!" Ye Fei nodded: "I asked my team members as soon as I came." ”

"Haha......" Professor Yuan laughed: "The people above have also heard about this, and they want to give you the first credit." ”

Ye Fei smiled and said, "It's not my credit alone, it's the credit of everyone in the laser laboratory." ”

"Don't be modest." Professor Yuan smiled: "The biggest credit for the whole experiment is you. ”

"You haven't seen the weapons simulated by supercomputing, let's go, I'll take you to see it, after reading it, you'll be even more shocked."

After speaking, Professor Yuan pulled Ye Fei and walked out.

They soon moved into supercomputing centers.

Zhonghu University has a supercomputing center, and Ye Fei has worked here for a while.

After entering the supercomputing center, many people greeted Ye Fei.

They went into one of the host rooms, where a lot of people were working.

After seeing Ye Fei and the others, they greeted Ye Fei and the others.

Professor Yuan said: "Call up the simulation map of the ground-based anti-satellite laser weapon. ”

"Good!"

Soon, the analogue of the ground-based anti-satellite laser weapon was called up.

"Ye Fei, look!" Professor Yuen pointed to the computer screen.

Ye Fei looked at it, and it was a weapon that looked very technological.

A wide open beam directionr, about a meter in diameter, is held in place by a disc underneath.

The style is like a large searchlight, from which a laser light is emitted.

"The illumination laser of the ground-based anti-satellite laser weapon is projected onto the target through a small-aperture beam directionfinder, and the reflected light is received by a large-aperture telescope, and the direction of the light is 50 years from the axis of the telescope......

Professor Yuan explained in detail the firing principle of ground-based anti-satellite laser weapons. ”

"Ground-based anti-satellite laser weapons, if placed on the ground, can destroy anything in the sky, such as airplanes, missiles, and even satellites."

"And if it's put on a satellite, it can destroy anything based on what the satellite observes."

"If a weapon approaches the Xia Kingdom, it can be destroyed in a microsecond."

"The people above are going to make forty-five ground-based anti-satellite laser weapons, and three of them will be placed in fifteen places in Xia Kingdom, so that the entire Xia Kingdom can be covered."

"We have large-scale destructive heavy nuclear weapons, as well as small destructive strike weapons, ground-based anti-satellite laser weapons."

"In the future, any enemy who wants to invade the Xia Kingdom will have to weigh it up and see if it can block the power of the ground-based anti-satellite laser weapon."

Ye Fei asked: "Are the people above going to install ground-based anti-satellite laser weapons on satellites?" ”

"Hmm!" Professor Yuan nodded: "After all, when it is installed on the satellite, every attack consumes the satellite too much, even if Xia Guo is very rich now, but the money is not spent like this." ”

Ye Fei said: "This is feasible, although it can't hit the whole world, but it's good to defend against Xia Kingdom." ”

"By the way, how did the people above solve it in terms of energy?"

"Some experts were consulted above, and eventually a power station was built next to all ground-based anti-satellite laser weapons and connected to the power systems of nearby cities."

"This solves the energy problem."

"One ground-based anti-satellite laser weapon works, and the remaining two are in reserve."

"After one is launched, it is immediately charged, and the other two are on top."

Ye Fei nodded: "This is a good way." ”

In this way, all the shortcomings of ground-based anti-satellite laser weapons can be solved in the best possible way.

Since the ground-based anti-satellite laser weapon test was in the final stage, Ye Fei did not leave Zhonghu University during this time.

I've been in the laser lab all the time.

A month later, ground-based anti-satellite laser weapons, data docking was completed.

Then comes the most critical part, the application of mathematics and the application of physics, which is manufacturing.

All the preparations are ready, and the manufacturing is simple.

A little more than a month later, the first ground-based anti-satellite laser weapon was created.

After experiments, the ground-based anti-satellite laser weapon was created with the same effect as the supercomputer simulation.

Department of Science and Technology. Zhang Gengye deliberately came to the laser laboratory, held Ye Fei's hand, and said excitedly: "Ye Fei, you are a national talent!" ”

"You've won a prize." Ye Fei said with a smile.

"Haha......" Geng Ye laughed and said: "No award, no award, I will report your credit to the above, and you will not be missing any of the benefits you deserve." ”

When the rest of the people heard this, they all looked at Ye Fei with envy.

With Ye Fei's credit, the country's support for him will be very great.

Geng Ye said: "Ye Fei, another project, you have to do it well, I look forward to your performance." ”

"I will." Ye Feidao.

Geng Ye patted Ye Fei's shoulder: "Young man, work hard, the future belongs to you." ”
