Seeing that the time was not early, Zhang Yuan walked briskly onto a rail shuttle bus and headed to the science conference hall. This time Europa expedition is not a sightseeing tour, and there are many things to do.

The conference room was crowded, and after he found Academician Ding, he sat down upright.

Academician Ding transmitted a document to him and instructed: "This kind of academic conference has been discussed many times for us, but for you, this is the first time. There are many general directions that we, the spacecraft researchers, 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 been ready for a long time."

Zhang Yuan was full of confidence, and he was already familiar with that paper. So that he can recite it backwards.

The theme of the conference was "Discussion on the Development of Future Industry", which included a lot of improvement work on the basis of the original industry of the new civilization.

The development of the earth's civilization to the present has formed a huge and complex industrial standard. Many of these industry standards are unreasonable, but due to historical intrinsic reasons, the cost of correction is so great that there is no way to correct it.

Academician Ding took the stage and talked eloquently.

“…… As a simple example, in the field of machining, the construction of second-order smooth spline surfaces on surfaces with complex topologies has always been a very important central problem......"

“…… We have made great progress in the mechanical engineering, automotive, and aerospace industries, and scholars and engineers have worked hard to construct smooth spline functions on manifolds. However, the results have been unsatisfactory, and there is always a singularity in the spline that deteriorates in smoothness. ”

"Can this be solved?"

"The answer is, no."

"Mathematically it has been proven that it can't."

A whisper sounded in the conference room, and Zhang Yuan also thought about it.

It was the first time he had heard these views, and it was interesting.

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

"The traditional way of constructing splines, including spline theory, is inherently irreparable, which leads to the futility of the natural generalization of traditional splines to manifolds, no matter how hard later generations try."

"For the specific certification process, you can refer to the following information......"

“…… I once looked through historical sources and found that the scholars did not care about this issue. At that time, the industry was not developed enough, and the parts that were machined were all quite simple, and there was no need to think too much about complex mathematics. When the engineers were building the entire standard, they were not aware of the technological crisis that could occur hundreds of years later......"

"The instability of the industrial base directly stifles the ceiling of the entire civilization. Our current industrial system has stabilized, and it is absolutely impossible to overturn it because of the unstable theoretical foundation. Think about it, how much does it cost to restart everything? All the parts have to be redesigned, is it realistic? Unrealistic. ”

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

Zhang Yuan didn't know much about this, but he still listened to it with interest.

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

It is very meaningful to use the current mathematical foundation to re-establish a complete industrial system. That will make the whole new civilization stronger, and the subsequent development will be smoother.

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

Academician Ding and they have other activities, Zhang Yuan plans to go around casually by himself, and then return to his residence to rest early.

There is also a hostess at the door, who is waiting warmly, she is a staff member who is specially responsible for receiving Zhang Yuan.

"Hi, 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 didn't feel too comfortable.

The girl said: "The temperature in your spaceship is 24 degrees all year round, and the cold resistance is not very good." Humans are creatures that degenerate quickly as long as they don't use them. ”

"Yes, in fact, our resistance and immunity will also deteriorate, and we are more likely to get sick if we return to Earth."

"Listen to your accent......"

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

On this alien planet, when the fellow sees the fellow, it is like a tearful eye.

"Are you also from Donghua City? Haha, what a coincidence! ”

The girl even wanted to help Zhang Yuan with his luggage, but Zhang Yuan hurriedly refused. It is impossible for a gentleman to let a girl take these things.

But in this ghost place, his body is light and fluttering, and he feels that this thing is in his hand, and his center of gravity is a little unstable, and he can't even walk.

"I'd better do it, there's no gravity anyway." Because she has lived here all year round, the girl named Jin Meilin has gradually become accustomed to Europa's gravity, and her pace is very steady.

In order to hide his embarrassment, Zhang Yuan asked casually: "You people here are generally taller, is it because of low gravity that the bones are elongated...... How tall were you? ”

"I was only 1.65 meters old, and I was pulled down 1.7 meters alive! In fact, girls don't need to grow so tall at all. It is also necessary to eat a kind of biological calcium every day to resist the loss of this calcium, which is troublesome. ”

The girl pursed her lips, pointed to the muscles in her thighs and said, "Like me, who have been here for a year, the muscles are not seriously atrophied, but if they stay for a long time, they 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 are so eager to rejuvenate the second spring!" ”

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

Jin Meilin smiled again and said: "Mr. Zhang, how can it be as you imagined, exercise can only slow down the degeneration of muscles, but not completely eliminate it." In particular, it is too difficult to recover from the decline of the breasts. Although, ha, it's very tall in this place, and when you return to Earth, it's like a ruined eggplant, it's hard to imagine......"

Zhang Yuan scratched his hair and smiled awkwardly.

He subconsciously glanced at the other party's chest, well, it was indeed very tall.

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

But staring at it for a long time, it doesn't seem polite, and after glancing at it, I don't look at it.

may be because it is rare to meet a fellow countryman, and 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 home planet.
