Chapter 280

In 5 years, as both sides gradually lowered their guards, the high-level visits between the two sides have become more frequent, especially the visits between scientists...

Scientists must be curious about the outside world. Scientists from Goer City are eager to experience life on spaceship and prepare for the possible interstellar voyage in the future.

Of course, the Gliese people will bring some technology belonging to their own civilization in exchange every time.

After the necessary safety tests and biochemical disinfection, the group of Gliese people dressed in spacesuits soon landed on the "Earth Era" and lived in their own living quarters.

This time guests from afar, except for some politicians, are mostly mathematicians. The main topics they talk about are some conjectures about "transcendence numbers". They will live in spaceship for half a year.

A little Pangolin came to the stage and introduced a new method of judging transcendental numbers.

Mathematics will always be the common language in the universe. The four ancient civilizations of mankind have all given birth to their own mathematical systems when they are not connected to each other. As a kind of "elegant art", a civilization that cannot enjoy the fun of mathematics is absolutely ignorant and uncivilized.

However, there are too few and too few mysteries that humans can solve for the endless comparisons of mathematics problems.

For a simple example, is π a transcendental number?

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

Is Euler's constant e a transcendental number?

Of course, it can also be proved!

What about e+π?

The answer is: I don’t know.

A question that sounds simple, but it is a world-class problem!

Even a mathematics master like Zhang Yuan cannot judge whether e+π is a transcendental number or not. The development of human mathematics to the present can only solve quite limited problems. Even if a computer can calculate (e+π) to several trillion digits, it is not much different from zero when compared with infinity.

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

The thinking of different civilizations is quite different, and there are places to learn from each other. This kind of communication is not as simple as 1+1.

Of course, these mathematical problems, for now, can hardly affect the productivity of the entire society, at most equivalent to the self-entertainment of top scientists.

For the orbit of the spacecraft with the highest precision requirements, the precision of Pi is only 15 or 16 decimal places. It doesn't matter whether Pi is a transcendental number or not.

10 decimal places are enough to make the Earth perimeter accurate to within 1 inch! 30 decimal places can make the all around of the entire visible universe accurate to an amount that even the most powerful Microscope can't distinguish! Therefore, regarding this knowledge, the two sides will openly communicate with each other, and the new civilization senior level does not prohibit such behavior, but implicitly encourages it.

But, why judge and solve these mathematical problems that seem insignificant?

Because...

It's right there!

"...The above is our latest research, about a way of judging beyond the number, thank you for listening, thank you."

The applause was thunderous, and the discussion was not continuous. Absolutely. Being able to receive a warm applause shows that the speech this time is still very popular.

And this group of Pangolin has also become accustomed to human etiquette and communication methods. They are wearing space suits. After being praised, they look quite satisfied.

"Professor Anbogu, regarding your inference 3.1.4, I have a slightly different view..." Zhang Yuan stood up, raised a few doubts, and received good answers.

After the first exchange meeting, these Gliese people will have more than ten days of rest, and then they will have the second and third exchange meetings. Humans have long been They have become accustomed to their work and rest.

Zhang Yuan didn’t want to wait for more than ten days. When the other party returned to the living area, he followed up and asked: “Then, Lord Gan Yaduo, what interesting trading ideas did you think of during your visit this time? Let’s talk about it first, let us be psychologically prepared."

"As long as it meets the demands of both parties, I believe that there is still a lot of room for negotiation..."

Humanity currently lacks There are many things, 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.

It is also a good choice to buy some from Gliese Civilization.

There are also some high-end robot chips and high-precision parts. If the Gliese people can produce them on their behalf, then the development of mankind will be smoother and the progress will be faster.

And most of what humans pay is entertainment products and their own technological heritage.

In fact, this kind of exchange is acceptable.

At this time, the other party brought a lot of goods, including more than 10,000 traditional silicon-based chips. This number is not too much compared to human needs, but it can be regarded as opening one. Good mouth.

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

Gan Yaduo turned his head, because he hadn't been dormant for a long time, he felt a little tired.

It said solemnly: "Your Excellency Zhang Yuan, our biggest appeal is, a Stellar Rank and other spaceship...The rest is easy to say, just an add-on to this spaceship."

"You also know that only motherships like Earth Era can take on the heavy responsibility of restarting a civilization, without letting the entire civilization go extinct in a different planet."

"And we still It requires interstellar colonization related technologies, such as space elevators, the structure of large-scale centrifugal wheels, and the structure of the ecological cycle system... We must at least learn to maintain the spaceship, right?"

This knowledge must be very expensive. The new human civilization is impossible at low prices, so it can only be traded slowly by little by little like this. Including those chips that are brought up, also belong to the category of transactions.

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

" But limited to productivity, we cannot produce such a giant spaceship for the time being. Even if humanity develops very smoothly, it will be a matter of one or two hundred years from now. We are impossible to promise something hundreds of years from now. ...This is responsible for both parties."

Gan Yaduo pointed to his feet: "no no no, I mean, how long is the service period of your current mothership, Earth Era?"

"Service period?"

This topic is a bit sensitive, but revealing a little information is not a big deal. Zhang Yuan said: "It depends on how the specific maintenance is. The main skeleton of spaceship is metal with higher strength. If it is placed in space, there will not be any change for thousands of years and tens of thousands of years."

"There may be some wear and tear on the bearing of the centrifugal wheel...and The lifespan of the radiation protection layer and the aerogel layer in the living area is shorter. The outer surface is a flexible material, which is almost fifty years old."

"There are also some electronic devices with a shorter lifespan. Years and several decades have to be replaced..."

"So, its service period, at least 50 years of lifespan."

So, if humans feel at ease The development of several decades has already been the change of Heaven and Earth turning upside down, and human beings will gradually live to the surface.

This original mothership will also be gradually eliminated. It is an inevitable event that humans have always lived in the spaceship.

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

"Do you mean..."

Zhang Yuan Wei Weiyi Surprised, I soon thought of a possibility.

Does this guy...want Earth Era spaceship?

Of course, not now, but waiting for several decades, after all human beings have moved underground and eliminated this spaceship...

Gliese people have the patience to wait .

Seeing Zhang Yuan’s doubts, Gan Yaduo explained: “We will choose a planet that is a little closer to serve as an immigration point, and strive to complete this time interstellar travel within five hundred to one thousand years... …Correspondingly, the spaceship we need must also have such a high service period."

"Buying a second-hand spaceship is almost our minimum requirement. I hope you can consider us Requirements."

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

This idea seems to be...not infeasible!

It can even be said...the feasibility is great!

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

"What?"

After hearing what Zhang Yuan said, everyone jumped up in surprise. Even Captain Zhao also started.

Recreating a spaceship that sails between stars may take one or two hundred years of human development, consume huge productivity, and even delay the development of other industries. So after thinking about it, I was a little reluctant.

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

However, if only a large-scale renovation of the Earth Era is carried out, the amount of engineering required and the difficulty are much smaller, perhaps only 30 to 40 years of development!

"Manufacturing and renovation are two completely different levels of difficulty. The skeleton of Earth Era is complete. If it is refurbished, it is not impossible to complete an interstellar journey."

Captain Zhao frowns, opened the mouth and said: "It is definitely feasible from an economic point of view... If our population has been completely relocated after several decades. Using it to replace a universal factory is a huge profit. Not too much!"

"Earth Era is a technology three thousand years ago after all. Now, we will definitely be able to build a better and better mothership."

Zhang Yuan also agrees: "Equivalent to they are a big step back, from a new spaceship originally needed, to a second-hand spaceship... Let's do the calculations, and how much work is needed to completely renovate the Earth Era? How much time can we make?"

For a while, everyone fell silent. If you want large-scale repairs, you must first have a large enough starry sky port and build a repair dock.

"It is estimated that this production goal will be completed in twenty years."

But Earth Era is indeed Immemorial old. If you want to continue your next starry sky journey, you must be fully great. cultivator. Except for some frameworks that do not need to be modified, the rest, including the living area, bearings, heat dissipation area, and central control area, must all be repaired.

One of the experts opened the mouth and 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 area computers where Gliese people participate in the manufacturing, which saves a lot of trouble."

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

Forty years, what a long number!

But it took forty years to complete this transaction. It is still very cost-effective for humans. At that time, the population was less than 5 million, and the combined productivity of everyone was even worse. A universal factory.

"Even without this transaction, humans would still have to build functional buildings such as the Starry Sky Harbor and the Dockyard."

"So, at most, some repair work ."

That's right!

Zhang Yuan suddenly asked Professor Xiang Yamamoto, "With 40 years of work, virtual technology can be developed, and then slowly guided and tempted to send all the Gliese people in the remaining 12 cities Virtual world?"

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

After listening to Zhang Yuan's proposal, the Conference Hall fell silent for a while.

Li Zhendong, who was sitting next door, couldn't help but scratched his head with his fingers. Zhang Yuan, how come... so many bad ideas?

He Li Zhendong still has to be shameless... The math meeting was held in a very friendly manner in the first few minutes, and in the next few minutes he secretly discussed to snatch others, which is really difficult to do.

No, it can be said that the entire human civilization needs a face!

Sending those drunken stupor guys into the virtual space, there is not much psychological burden, but now... Goertek is already the last hope of this civilization!

"Well, it's my fault..." After some calculations, Zhang Yuan each minding their own business rejected this plan.

"Although this plan will bring short-term benefits, in the long run, plundering will cause unfriendly deviations in the people's ideology, and it is not conducive to our entire school's governing philosophy..."

p>

"If we have 12 universal factories, there is no need to snatch someone else's for one..."

There is nothing wrong with being greedy, but being greedy is always a sin. .

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

" I know that the work, rest and life cycle of the Gliese people are different from ours. We think that forty years are very long, but they don’t think so. Forty years is almost the same as our four years. It is basically impossible to generate a huge consciousness. Transformation."

"So, even if the virtual technology comes out, it is impossible to completely brainwash them in just 40 years..."

"It's almost the same in one or two hundred years... "

Zhang Yuan agreed with this point of view: "Well, that is, time is not allowed at all... Then within 40 years, first try to win the most easily available universal factory. It’s also good to leave a fire for Gliese civilization. Hey, let’s do it, this disaster-prone civilization."

Everyone was inexplicably sighed in relief and began to discuss the next construction and rectification.

After thinking for a while, Captain Zhao thought of something again, said with a bitter smile: "Everyone, if you trade with the spaceship'Earth Era', there is another thing I worry about."

"It is the issue of folk emotions. Our group of people thinks a bit different from the folks."

"From a purely utilitarian point of view, renovate it , Selling, is indeed the best choice, there is no big problem."

"But the people can't control so much. I can already expect this kind of opposition to covering the mountains and plains. Sounds. This mothership has accompanied us for three thousand years...The long star road finally reached the destination, accompanied us to develop, and gained a foothold in this alien planet."

"As a result, after squeezing the last bit of surplus value, I want to sell it again? What is the difference between this and selling my old mother?"

"That's right!" Information scientist Li Zhendong knocked on the table and touched his chest. "I said, it always feels a bit wrong. It turned out to be like this! 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 population is moved to the surface, what is the use of this spaceship? Now It can also be used as a space elevator, but after the construction of the Starry Sky Port, the space elevator will not be used as it. Just put it aside and let it be scrapped? Or use it as an amusement park or a museum?"

" It will slowly wither and die there!"

"A few hundred years later, does anyone remember its existence?"

A deputy captain interjected: "At least Bring a sense of security. For the people, it’s good to put it there and wither... People will feel reluctant, and feel that even if it’s left there, it’s better than selling it."

"What sense of security If there is a war, it can still take everyone away? We can develop special interstellar war weapons, rail guns and drones, and still need this scrapped mothership?!"

Zhang Yuan found that he was a little agitated, and quickly cleared his throat.

He exhilaratedly said: “In fact, the issue of public opinion is very simple. I thought of a propaganda slogan: Instead of letting our mothership sit idle here and die alone, it’s better to let her carry another The hope of a civilization, once again..."

"Set sail!"

"Complete your own glorious journey. To a civilization's... Is the greatest significance of her existence!"
