Chapter 250

On the fourth day, Gliese civilization held another Mathematics Conference. Because Zhang Yuan himself was a mathematics expert and didn't slack off in learning over the years, he was duty bound to participate in the conference on behalf of mankind.

All the stories are very profound. To Zhang Yuan's shock, other disciplines will not comment for the time being. The civilized mathematics is really powerful!

Even, it may be better than human mathematics!

In human society, there are many mathematical directions, even the foundation has not been laid, but it has been perfected and confirmed by Gliese civilization!

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

"Our best idea at present is this..."

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

Like a raging flame burning in the chest, this kind of communication really has a hearty pain and pleasure!

Of course, Zhang Yuan was not humiliated by human mathematics. The mathematicians of the other side shouted and were surprised about the "great unification of mathematics" plan and some grand programs, including a small part of the history of new civilization, plus the alien paper cheated from zero XZ.

The thinking direction of both sides is very surprised. There are many places that can be made up for each other only in mathematics.

After the meeting, Zhang Yuan deeply understood the benefits of such exchanges between different races.

There are some wonderful ideas, if according to human thinking, they may never be thought of.

He thought secretly: "if a civilization is broad enough, the alliance of multiple civilizations will be stronger than a single civilization..."

"... Mr. Ambo, the mathematics you have given is indeed a very remarkable achievement. But I noticed that they are all old things forty or fifty thousand years ago... Can you reveal your latest progress in mathematics? "

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

Mathematics is black and white. Right is right and wrong is wrong. Meeting objects that can be communicated can really shorten the distance quickly, and even race is not very important.

In any case, these things can be said to exist as high and few, and it is too difficult to convert them into productive forces.

The Gliese professor named "Ambo" has fallen into a state of almost fanaticism in the Mathematics Conference. Even if the conference is over, he still has a little meaning and keeps asking questions behind Zhang Yuan.

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

"Alas, it's not that I don't want to say..." university student Ann Bowe sighed, "it's really... Not worth mentioning! It's not worth mentioning! "

It left in great frustration. Before leaving, it seemed that the whole back was bent.

Back in the residential area, he asked several partners again. Zhang Yuan suddenly found that almost all the contents exchanged in recent days were excellent cultures before the emergence of the second alien civilization.

There is no history since the second alien civilization.

There are some guesses in Zhang Yuan's heart, "that is to say, after the emergence of the second interstellar civilization, did something happen quickly..."

It's strange, really strange

"Even, the second interstellar civilization does not necessarily have goodwill..."

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

Finally, a week later, all the art and science exchanges were over, and all the senior executives came to the table and started the final cooperation negotiations.

There is no good ink. Zhang Yuan opened the door to the mountain road: "... Dear Mr. ganyaduo, after so long communication, we can really understand and appreciate each other."

"Cooperation is of course the best choice for both of us. We have no deep hatred, and there is no need to fight for a planet. "

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

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

The Gliese civilization leader stopped talking, and then several people looked at each other, as if they had made up their mind.

Ganyaduo suddenly said, "we... Want a spaceship!"

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

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

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

At first, he thought that the other party wanted the human "earth times", which was certainly impossible. After two seconds of silence, he realized that the other party didn't mean that.

"Impossible!" After rejecting the other party, he added: "... At least for now, it is impossible."

"Our human civilization can indeed produce stellar spaceships, and has produced more than one in a long history. But that is our powerful mother civilization, not our current child civilization. "

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

These are big truths that fools can analyze. If human beings can produce stellar spaceships, they will crush the Gliese civilization and negotiate farts.

Moreover, 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 if there is such a construction plan in the future planning, these spacecraft are used to realize the "sowing plan" and "wandering plan".

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

Zhang Yuan is frowning and worrying about the gains and losses. If he has to consume the development time of the whole civilization for decades or hundreds of years just to get some knowledge, he has to consider whether it is cost-effective.

"If the benefits are big enough, it's not bad... But if it's just mathematical knowledge... No." He shook his head gently, even if he was a mathematician, curious about the solutions to some mathematical problems. He cannot sell the interests of the whole human civilization out of curiosity.

The other party asked, "what do you think we need to pay in exchange for a spaceship?"

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

"The more difficult the spacecraft, the higher the cost... The price... Is actually difficult 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 must be able to afford it! "

As a result, it actually came up with a very detailed plan, including the parameters of the spacecraft ecosystem, the population that can be carried, etc. it was obviously planned for a long time, not a temporary intention!

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

"Wang Junpeng, what's the situation? This transaction requires that even I can't make a direct decision... Earth time spent tens of millions of engineers' productivity and the whole 30 years of construction, you know? We have 500000 people now... "Zhang Yuan asked softly in his earphone.

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

Do these Gliese want to emulate human beings and colonize deep space? This is incredible!

"They don't want this planet?"

“……”

Zhang Yuanqing cleared his throat and returned to normal. He carefully pondered the plan given by the other party, and his eyebrows were frowned and stretched.

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

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