Deep Space Fleet

Seeing that it was getting late, Zhang Yuan quickly boarded a rail shuttle and headed for the Science Conference Hall. The Europa expedition this time is not a sightseeing tour, and there are still many things to do.

The meeting room was crowded with people. After finding Academician Ding, he sat upright.

Academician Ding transmitted a document to him and ordered: "We have discussed this kind of academic conference many times for us, but it is the first time for you. There are many general directions, and it is our spaceship scientific research. People need to study in the future. You can choose which reports you want to hear."

Zhang Yuan nodded.

"On the fifth day of the meeting, you still have a report on turbulence, are you ready?"

"No problem, it's already ready."

Zhang Yuan is full of confidence, he has already mastered that thesis by heart. Let him recite it backwards.

The theme of this meeting is "Discussion on the Development of Future Industry", which includes a lot of improvement work of the new civilization on the basis of the original industry.

With the development of earth civilization to the present, a huge number of complex industrial standards have been formed. Many of these industry standards are unreasonable, but due to inherent historical reasons, the cost of correction is so huge that there is no way to correct them.

Academician Ding came to the stage and talked eloquently.

"...To give a simple example, in the field of mechanical processing, the construction of second-order smooth spline surfaces on surfaces with complex topologies has always been a very important central issue..."

"...We have achieved very long-term development in the machinery manufacturing, automobile, and aviation industries. Scholars and engineers have worked hard to construct smooth spline functions on manifolds. But the results have not been ideal, and splines always exist. Singularity where the smoothness becomes worse."

"Can this problem be solved?"

"The answer is, no."

"It has been proved mathematically that it cannot."

There were whispers in the meeting room, and Zhang Yuan also thought about it.

It was the first time he had heard these views, and they were very interesting.

Academician Ding continued: "Why not? Because the industrial system established at the beginning was wrong."

"The traditional spline construction method, including spline theory, has irreparable defects, which leads to the futility of the natural extension of traditional splines to manifolds no matter how hard the posterity tries."

"For the specific proof process, you can read the following information..."

"... I once looked through historical materials and found that the scholars at the time did not pay attention to this issue. The industry was not developed enough at the time, and the parts processed were all quite simple, so there was no need to consider too much complicated mathematics. The engineers at the time were establishing the entire standard. At that time, I didn't realize the technological crisis that might appear hundreds of years later..."

"The instability of the industrial foundation has directly killed the upper limit of the entire civilization. Our current industrial system has become stable, and it is absolutely impossible to overthrow it because of the unstable theoretical foundation. Think about it, everyone, push everything back to the beginning , How much will it cost? All parts have to be redesigned, is it realistic? Not realistic.”

"So, our future can only be limited to partial repairs, which is another kind of sadness..."

Zhang Yuan didn't know much about this aspect, but he still listened with gusto.

The key work they will be engaged in in the future should be the reformulation of industrial standards for the new civilization.

It is a very meaningful thing to use the current mathematical foundation to rebuild a whole set of industrial systems. That will make the entire new civilization stronger, and the subsequent development will be smoother.

It wasn't until ten o'clock in the evening that the first day's academic conference officially ended, and I was exhausted.

Academician Ding and the others have other activities, and Zhang Yuan plans to go for a casual stroll by himself, and then return to the place of residence earlier to rest.

There is another host at the door who is waiting enthusiastically. She is a staff member who is responsible for receiving Zhang Yuan.

"Hello."

"Hello!"

Shrugging his shoulders, Zhang Yuan felt a little cold. The temperature here is only more than ten degrees all year round, which is not high. It may be to ensure that the heat dissipation does not exceed the standard. He doesn't feel too well.

The girl said: "The temperature inside your spaceship is 24 degrees all year round, and the cold resistance is not very good. Human beings, as long as they don't use things, they will degenerate quickly."

"Yes, in fact, our resistance and immunity will also deteriorate. If we return to the earth, we will be more likely to get sick."

"Listen to your accent..."

Coincidentally, the girl who received Zhang Yuan was also from the Xia Kingdom, and she even had a Donghua accent in her accent.

On this alien planet, when a fellow countryman sees a fellow countryman, tears are almost in tears.

"Could it be that you are also from Donghua City? Haha, what a coincidence!"

The girl even wanted to help Zhang Yuan with his luggage, but Zhang Yuan quickly refused. A gentleman can never let a girl take these things.

But in this ghostly place, his body was so light, he felt that he was holding this thing in his hand, and his center of gravity was a little unstable, and he couldn't even walk.

"Let me do it, there is no gravity anyway." Because she has lived here all year round, the girl named Jin Meilin has gradually gotten used to the gravity of Europa, and her steps are very steady.

In order to hide the embarrassment, Zhang Yuan asked casually: "People here are generally taller. Is it because of the low gravity that the bones have been stretched... How tall are you?"

"I used to be only 1.65 meters, but I was pulled down to 1.7 meters! In fact, girls don't need to grow so tall. I have to eat a kind of biological calcium every day to resist this loss of calcium. It's so troublesome."

The girl curled her lips, pointed to the muscles on her thighs and said: "Like me, if you come here for a year, the muscle atrophy is not serious, but if you stay for a long time, it will degenerate like cotton, soft. "

Zhang Yuan smiled: "It's great to be able to grow taller. Many boys who are stuck at 1.69 meters long for a second spring!"

"As for muscle atrophy, there are many ways to solve it, such as exercising, using centrifugal force to simulate gravity, etc. If you return to the earth, it will take a while to recover, so don't worry too much."

Jin Meilin smiled again and said: "Mr. Zhang, it is not as you imagined. Exercise can only slow down the degeneration of muscles, but cannot completely eliminate it. Especially the degeneration of the chest, it is too difficult to recover. Although, ha, in this The place is very tall and straight, and after returning to the earth, it is like a dried eggplant, which is really unimaginable..."

Zhang Yuan scratched his hair and smiled awkwardly.

He subconsciously glanced at the other person's chest, well, it was indeed tall and straight.

Even, the buoyancy of the air is already comparable to the gravity of the earth, and it can be said that it has become the most perfect shape.

But it seems impolite to stare at it for a long time, so I don't look at it after a glance.

Probably because it was rare to meet fellow villagers, the two quickly became acquainted. The girl in charge of the reception was very cheerful and took Zhang Yuan to visit the various equipment in the base. These devices may also appear in the future parent star.
