Deep Space Fleet

For 5 years, with the gradual easing of the alert on both sides, mutual visits between high-level officials on both sides have become more frequent, especially among scientists ...

Scientists must always be curious about the outside world. Scientists from Gore City are eager to experience life on the spacecraft and prepare for possible interstellar voyages in the future.

Of course, every time the Glitz people bring some technology that belongs to their own civilization in exchange.

After the necessary safety inspections and biochemical disinfection, soon these Glitzers wore space suits, landed on the "Earth Age" again, and lived in their own living areas.

Except for some politicians, most of the guests who came this time were mathematicians. The main topic of discussion was some conjectures on "transcendental numbers". They would live in the spacecraft for half a year.

A small pangolin came to power and introduced a new method for judging transcendental numbers.

Mathematics will always be the same language of the universe. The four ancient civilizations of mankind once gave birth to their own mathematical system without mutual connection. As a "refined art", a civilization that cannot enjoy mathematical fun is absolutely ignorant and uncivilized.

But by contrast, the mysteries of human beings are too few and too few.

For a simple example, is π a transcendental number?

It can be proven that it is indeed a transcendental number.

Is Euler's constant e transcendental?

Yes, of course!

What about eπ?

The answer is: I don't know.

It sounds simple, but it is a world-class problem!

Even a master of mathematics like Zhang Yuan, there is no way to determine whether eπ is a transcendental number. Since the development of human mathematics, only limited problems can be solved. Even if a computer can calculate (eπ) to several trillion trillion digits, it is not much different from zero compared to infinity.

And the exchange of civilization and civilization can indeed quickly promote the development of these disciplines.

The thinking of different civilizations is very different, and there are places to learn from each other. This kind of communication is not as simple as 11.

Of course, for the time being, these mathematical problems are difficult to affect the productivity of the entire society, at best equivalent to the entertainment of top scientists.

For the orbit of the spacecraft with the highest accuracy, the accuracy of the pi rate is also 15 or 16 decimal places. It doesn't matter much whether the pi rate is a transcendental number.

Ten decimal places is enough to make the perimeter of the earth accurate to within one inch! 30 decimal places can make the entire visible universe accurate to an amount that even the most powerful microscope cannot distinguish! Therefore, regarding these knowledge, the two sides can generously come out to communicate with each other, and the high-level of the new civilization will not forbid such behavior, but will faintly encourage it.

But why judge mathematical problems that seem insignificant?

because……

It's right there!

"... The above is our latest research. Regarding a method of judging transcendental numbers, thank you all for listening, thank you."

There was thunderous applause from below, and the voice of discussion was endless. Flash Dance can be applauded warmly, indicating that this speech is still very popular.

This group of pangolins has also become accustomed to human etiquette and communication methods. They are wearing space suits, and after being praised, they look quite satisfied.

"Professor An Bogu, I have a different opinion about your inference 314 ..." Zhang Yuan stood up, raised a few doubts, and received good answers.

After the first exchange meeting, this group of Glizzards will have a rest period of more than ten days, and then the second and third exchange meetings will take humans for a long time.

Zhang Yuan didn't want to wait for more than a dozen days. When the other party returned to the living area, he asked along the way: "So, Lord Gan Yaduo, what interesting trading ideas did you come up with this visit? Let's talk about it first, let We are mentally prepared. "

"As long as the demands of both parties are met, I believe that there is still a lot of room for discussion ..."

There are a lot of things that human beings lack, such as smart phones, which can significantly improve the quality of life of ordinary people, but they are not the focus of the development of a new civilization at all.

Buying some from Glitz civilization is also a good choice.

There are also some high-end robot chips and high-precision parts. If the Glize people can produce it for them, the human development will be smoother and the progress will be faster.

What humans pay for is mostly entertainment products and their own scientific and technological heritage.

This exchange is actually acceptable.

This time, the other party brought a lot of goods, including more than 10,000 traditional silicon-based chips. This quantity is not too much compared with human demand, but it is also a good word.

Scientists are examining the quality of these products and studying compatibility issues.

Gan Yaduo turned his head, because he didn't sleep for a long time, he felt a little tired.

It solemnly said: "His Excellency Zhang Yuan, our biggest appeal is a stellar-class spacecraft ... Everything else is easy to say, just an addition to this spacecraft."

"You also know that only mother ships like the Earth Age can suffice to restart a civilization without destroying the entire civilization on a different planet."

"And we also need technology related to interstellar colonization, such as the construction of space elevators, large-scale centrifugal wheels, the construction of ecological circulation systems ... We must at least learn to repair spacecraft, right?"

This knowledge must be very expensive, and the new human civilization cannot be sold cheaply, so it can only be traded slowly and bit by bit. Including those chips brought in, also fall into the category of transactions.

Zhang Yuan nodded, and said, "I'm sorry, personally, I really want to make this biggest deal and create a giant mothership to help you leave this planet ..."

"But limited to productivity, we are unable to produce such a giant spacecraft for the time being. Even if human beings develop very smoothly, it will be a hundred or two hundred years later. We cannot promise something that will be hundreds of years later ... This is for both parties. Be responsible for."

Gan Yaduo pointed at his feet: "No, no, no, I mean, how long is the service life of your current mothership, the Earth Age?"

"Term of service?"

This topic is a bit sensitive, but revealing a little information is not a problem. Zhang Yuan said: "It depends on the specific maintenance. The main skeleton of this spacecraft is high-strength metal. If it is placed in space for thousands of years, Nothing will change for tens of thousands of years "

"There may be some wear on the bearings of the centrifugal wheel ... and the radiation protection layer and aerogel layer in the living area have a shorter life. The exterior is a flexible material, almost fifty years."

"There are also some electronic devices that have even shorter lifespans. They have to be replaced after a few years or decades ..."

"So, its service life has at least fifty years of life."

Therefore, if human beings develop with peace of mind for decades, it will already be an earth-shaking change, and human beings will gradually be able to live on the ground.

This original mothership will also be gradually eliminated, and humans cannot always live in the spacecraft, which is an inevitable event.

"So, is it still possible to re-complete an interstellar journey?"

"what do you mean……"

Zhang Yuan was a little surprised, and soon thought of a possibility.

Could this guy ... want the Earth Age spaceship?

Of course, not now, but for so many decades, after all human beings have moved underground and the ship has been eliminated ...

Some of the Glitzers waited patiently.

Seeming to see Zhang Yuan's doubts, Gan Yaduo explained: "We will choose a closer planet as a settlement, and strive to complete this interstellar journey within five hundred to one thousand years ... Correspondingly, we need The spacecraft must also have such a high service life. "

"Purchasing a used spacecraft is almost our minimum requirement, and we hope you will consider our requirements carefully."

Watching this leader leave, Zhang Yuan kept pondering in his heart.

This idea seems to be ... not without feasibility!

It can even be said ... feasibility!

He soon brought the news back into the captain's room.

"what?"

After listening to Zhang Yuan's report, everyone jumped in surprise. Even Captain Zhao was taken aback.

Rebuilding a spacecraft sailing between stars may take one to two hundred years of human development time, consume huge productivity, and even delay the development of other industries. So after thinking about it, a little reluctantly.

Even if you get a universal factory, you will lose too much.

However, if only the Earth Age is renovated on a large scale, the amount of engineering and difficulty required will be much smaller, maybe only 30 to 40 years of development!

"Manufacturing and refurbishment are two completely different difficulties. The skeleton of the Earth Age is complete. If it is renovated and completed an interstellar journey, it is not impossible."

Captain Zhao frowned, and said, "It must be feasible from an economic point of view ... If our population has been completely relocated after decades, using it to exchange for a universal factory can be said to be a big profit and a special profit. Minute!"

"After all, the Earth Age technology was 3,000 years ago. Now, we can definitely build a better and better mothership."

Zhang Yuan also agreed: "It's equivalent to taking a big step back from replacing the new spacecraft that was originally needed to a second-hand spacecraft ... Let's do the math, how much work is needed to rebuild the Earth Age completely. Volume, how much time can we earn? "

At one and a half minutes, everyone was silent, and in order to do large-scale repairs, they must first have a large enough starry sky port to build a repair dock.

"It is estimated that this production target can be achieved in two decades."

But Earth Age is indeed too old, if you want to continue the next star journey, you must completely overhaul. Except that some framework skeletons do not need to be modified, the rest, including the living area, bearings, heat dissipation area, and central control area, have to be repaired.

One of the experts said: "... Allocate a certain production line and add 80,000 people to this repair work. It is conservatively estimated that these repairs should be completed in 20 years. There are some core areas of computer degliser People involved in manufacturing themselves saved a lot of trouble. "

"20 plus 20, that is, will it take at least forty years to complete this transaction ..."

Forty years, what a long number!

But it took 40 years to complete this transaction, which is still very cost-effective for human beings. At that time, the population was less than 5 million, and the combined productivity of all people may not even be comparable to a universal factory.

"Even without this deal, human beings still have to build star-ports, docks and other functional buildings."

"So, at best, it's just repair work."

correct!

Zhang Yuan suddenly asked Professor Xiangshanben, "Forty years of work, we can develop virtual technology, and then slowly guide and seduce all the Glize people in the remaining 12 cities into the virtual world?"

"If there are 12 universal factories, the troublesome business of this one can be avoided, and we can even grab it directly ..."

After listening to Zhang Yuan's proposal, the meeting room fell into silence for a time.

Li Zhendong, who was sitting next door, couldn't help disabling his fingers and scratching his head. Why, Zhang Yuan, this guy has so many bad ideas?

He still had to be shameless ... The first few minutes were still very friendly to hold a mathematical conference, and the next few minutes secretly discussed to **** others, which is really difficult to do.

No, let alone say that the entire human civilization has a face!

Sending those drunk and dreamy guys into the virtual space does not have much psychological burden, but now ... Gol City is already the last hope of this civilization!

"Okay, it's my fault ..." After calculating it, Zhang Yuan rejected the plan by himself.

"Although this plan will bring short-term benefits, in the long run, plundering will make the people's ideology not very friendly and bias, and it is not conducive to our entire school of thought ..."

"If we have 12 universal factories, there is no need to **** others for one ..."

Greed is not a big mistake, but insatiable greed is always a sin.

Immediately after, Zhao Qingfeng rejected Zhang Yuan's plan from another angle: "Even if this technology is successfully developed, forty years will definitely not be enough!"

"You know, the Glidze people's schedule and life cycle are different from ours. We think that forty years are very long, but they don't think so at all. Forty years are almost the same as our four years, and it is impossible. Produces a huge ideological shift. "

"So, virtual technology is calculated, and it is impossible to completely brainwash them in just forty years ..."

"It's almost one or two hundred years ..."

Zhang Yuan agreed with this view: "Well, is that time not allowed at all ... then in 40 years, try to fight for the most accessible universal factory first, and leave a fire for Glize civilization. That's right. That's it, this civilized disaster. "

Everyone breathed a sigh of relief, and began to discuss the next construction rectification.

After thinking for a while, what Captain Zhao thought about, he said with a bitter smile: "Everyone, if I use the" Earth Age "spacecraft to trade, I am worried about another point."

"That is the problem of folk emotions. The thinking of our group of people is always a little different from that of folks."

"From a purely utilitarian perspective, refurbishing and selling it is indeed the best choice, without much problem."

"But the people can't control so much. I can already predict that this kind of opposition voice is everywhere. This mothership has accompanied us for three thousand years ... The long road to the stars finally reached our destination and accompanied us. As it develops, it has a foothold on this alien planet. "

"After selling out the last surplus value, I want to sell it again? How is this different from selling my old mother?"

"Right!" The information scientist Li Zhendong knocked on the table and touched his chest again. "I said, I always feel a bit wrong. It turned out to be this way! So this plan is not easy to pass!"

Zhang Yuan sneered, "Sell your old mother? This is really stupid ... no, emotional!"

"Then you say, when all the people move to the surface, what is the use of this spacecraft? It can still be used as a space elevator, but after the construction of the starry sky port, the space elevator will not be used as a space elevator. Is it scrapped? Or is it an amusement park or museum? "

"It will only slowly die there and die!"

"A few hundred years later ~ www.novelmtl.com ~ Do anybody remember its existence?"

A deputy captain interjected: "At least it can bring a little sense of security. For the people, it is good to leave there and die ... People will not be willing to feel that it is better to leave it idle than to sell it."

"What sense of security? If it really fought, it would take everyone away? We could develop specialized Star Wars weapons, railguns, and drones, and would we need this scrapped mothership? ! "

Zhang Yuan found that he was slightly agitated and cleared his throat.

He exhilarated, "In fact, the issue of public opinion is very simple, but I thought of a propaganda slogan: Instead of letting our mother ship idle here and die alone, it is better to let her carry the hope of another civilization, once again ... "

"start sailing!"

"Completing her own glorious journey, for a civilized ... salvation journey, this is the greatest significance of her existence!"
