Chapter 244

On the fourth day, glitzer civilization held another Mathematics Conference. As Zhang Yuan himself was a mathematics expert, he did not slack off his study in these years, so he was duty bound to attend the conference on behalf of mankind.

All the stories are very abstruse. To Zhang Yuan's surprise, other subjects will not comment on them. This civilized mathematics is really powerful!

Maybe even better than human mathematics!

In human society, there are many mathematical directions, even the foundation has not been laid, but it has been proved by the improvement of glitzer civilization!

"I have another question about your idea. By the way, in our language, it's called Hodge's conjecture... "

"Our best idea at the moment is this..."

After three hours of discussion, Zhang Yuan became more and more excited and his old face turned red.

As if a group of flames burning in the chest, this kind of communication really has a kind of heartfelt pain!

Of course, human mathematics did not disgrace Zhang Yuan. The plan of "great unification of mathematics" and some grand programs, including a small part of the new civilization history, together with the alien paper cheated from zero XZ, also surprised the mathematicians of the other side.

There is a big surprise in the thinking direction of both sides. There are many things that can make up for each other just in mathematics.

After the meeting, Zhang Yuan was deeply aware of the benefits brought by the exchange between different races.

There are some fantastic ideas that may never come to our mind if we follow our own thinking.

He thought in his heart: "if a civilization's mind is broad enough, a multi civilization alliance will be stronger than a single civilization..."

“…… Mr. Ambow, the mathematics you gave us is really a great achievement. But I noticed that they were all forty or fifty thousand years old Can you tell me about your latest progress in mathematics? "

Zhang Yuan asked casually when he came out of the meeting room.

Mathematics is black and white. Right is right and wrong is wrong. When we meet people who can communicate with each other, we can really get closer. Even the race is not very important.

In any case, these things can be said to exist like a few, and it is too difficult to transform them into productive forces.

This glitzer professor named "Anbo" has fallen into an almost fanatical state in this mathematics conference. Even if the conference is over, he still has a little more meaning and keeps asking questions after Zhang Yuan.

However, hearing Zhang Yuan's inquiry, his enthusiasm seemed to be suddenly quenched by a basin of cold water.

"Well, it's not that I don't want to say..." "It's really It's not worth mentioning! It's not worth mentioning! "

It is very depressed to leave, before leaving, as if the whole figure are bent up.

After returning to the residential area and asking some of his friends, Zhang Yuan suddenly found that almost all the contents of the exchange these days were excellent cultures before the emergence of the second alien civilization.

There is no history since the second alien civilization.

Zhang Yuan had some conjectures in his mind, "that is to say, after the emergence of the second interstellar civilization, did the problem quickly appear..."

It's very strange, really strange

"Even, the second interstellar civilization may not be well intentioned..."

"But why help them develop into the power age?"

Finally, a week later, all the art and science exchanges ended, and all the high-level officials came to the table and started the final cooperation negotiation.

There's nothing to write about, either. Zhang Yuan comes to the mountain road Dear Mr. ganyaduo, after so long exchanges, we can really understand and appreciate each other. "

"Cooperation is certainly the best choice for both of us. We don't have a deep hatred, and we don't have to fight for a planet. "

"The starry sky is so vast that our human eyes will never be limited to one planet."

Zhang Yuan said tentatively, "but I want to know what kind of cooperation do you want? Is it trade or scientific and technological exchanges between the two sides? Or cultural development... "

The leader of the glitzer civilization stopped talking, then several people looked at each other and seemed determined.

Ganyaduo suddenly said, "we I want a spaceship

"A spaceship that can navigate between stars, for which we can pay almost anything!"

"Including the knowledge you want, as well as a large number of production tools, can be used as the subject of the transaction."

Zhang Yuan's pupils contracted slightly. He was surprised. Suddenly, cold sweat came out of his back!

At the beginning, he thought that the other party wanted the "earth age" of human beings. Of course, it was impossible. After two seconds of silence, he realized that the other party didn't mean that."No way!" After rejecting the other party, he added: "it's For the time being, at least, it's impossible. "

"We human civilization can indeed produce star class spaceships, and in the long history, we have produced more than one. But that's our powerful mother civilization, not our present child civilization. "

"The current productivity is far from being able to produce star class spacecraft. We need at least one or two hundred years of development So I'm sorry I can't accept your request for the time being. "

These are big truths, which can be analyzed by fools. If human beings can produce stellar spaceships, they will crush the glitzer civilization, and they will not be able to negotiate.

What's more, the cost of building a star class spacecraft is too high. Each one has to occupy a huge amount of productivity of the new civilization.

Even in the future planning, there are such construction plans, but these spaceships are used to realize the "sowing plan" and "wandering plan".

"If you sell a spaceship to the glitzers..."

Zhang Yuanzheng frowned and worried about the gains and losses. If only in order to gain some knowledge, it would take decades or hundreds of years for the development of the whole civilization, then we have to consider whether it is cost-effective.

"If the benefits are big enough, it's not impossible But if it's just math No way. " He shook his head slightly, even though he was a mathematician, curious about the solutions to some difficult mathematical problems. It is impossible for him to betray the interests of the whole human civilization just because of curiosity.

Then the other side asked, "what do you think we need to pay for a spaceship?"

After a while, Zhang Yuan said: "Mr. ganyaduo, I think you may underestimate the difficulty of building a star class spacecraft. What size ship do you need? How many people to carry and how far to sail? And the complexity of the ecosystem How many production tools need to be carried inside? These are all things to consider. "

"The more difficult the spaceship is, the higher the cost will be The price It's hard to estimate

Ganyaduo said directly: "we have been thinking about this problem for a long time. Price is not a problem, as long as your civilization can be built We can certainly afford it

As a result, it actually came up with a very detailed plan, including the parameters of the spacecraft ecosystem, the population it can carry, and so on. Obviously, it has been planning for a long time, not a temporary idea!

So much so that the whole negotiation team was a little confused and looked at each other in astonishment.

"Wang Junpeng, what's the situation? Even I can't make a direct decision on this transaction request Earth age spent tens of millions of engineers' productivity, the whole 30 years of construction, you know? We have 500000 people now... " Zhang Yuan asked softly in the earphone.

Wang Junpeng was also stunned. As the first group of diplomats to come here, he was also stunned at the moment, "I really I don't know what they really think

Do these glitzers want to follow the example of human beings to colonize deep space? It's incredible!

"They don't want this planet?"

“……”

Zhang Yuan cleared his throat and returned to normal again. He carefully pondered over the plan given by the other party, and his brows suddenly wrinkled and stretched.

The reward given by the other party is indeed very rich. It will not only give us precious knowledge, including mathematics and cosmology, but also give us some precious heritage left by alien civilization!

Including a The so-called "fully automatic universal factory"!
