Chapter 102

Seeing that it was not early, Zhang Yuan quickly stepped onto a rail bus and went to the science conference hall. This Europa expedition is not a sightseeing tour. There are still many things to do.

There were so many people in the conference room that he found academician Ding and sat upright.

Academician Ding transmitted a piece of information to him and said, "this kind of academic conference has been discussed many times for us, but it's the first time for you. There are many general directions that we spacecraft researchers need to study in the future. You can choose what you want to hear. "

Zhang Yuan nodded.

"On the fifth day of the meeting, you still have a lecture on turbulence. Are you ready?"

"No problem, it's already ready."

Zhang Yuan is full of confidence. He has already been familiar with that paper. He can recite it upside down.

The theme of this conference is "Discussion on the development of future industry", which includes a lot of improvement work of new civilization on the basis of original industry.

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

Academician Ding came to the stage and talked.

“…… For a simple example, in the field of machining, it is always a very important central problem to construct second-order smooth spline surfaces on surfaces with complex topology. "

“…… We have made a very long-term development in the mechanical manufacturing industry, automobile industry and aviation industry. Scholars and engineers have made great efforts to construct smooth spline functions on manifolds. However, the results are not ideal, and there are always singular points with poor smoothness

"Can this problem be solved?"

"The answer is, No."

"It's mathematically proven that it can't be."

There was a murmur in the conference room, and Zhang Yuan was thinking about it.

It's the first time he's heard these ideas. It's very interesting.

Academician Ding continued: "why not? Because the original industrial system was not right. "

"The traditional spline construction, including spline theory, has its own irreparable defects, which leads to no matter how hard the later generations try, the natural generalization of traditional spline to manifold will be futile."

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

“…… I have looked through the historical materials and found that the original scholars did not care about this problem. The original industry is not developed, processing parts are quite simple, do not need to consider too much complex mathematics. When the original engineers established the whole standard, they didn't realize the technical crisis that might appear hundreds of years later.... "

"The instability of the industrial base has directly strangled the upper limit of the whole civilization. Our current industrial system has become stable. It is impossible to start over because of the unstable theoretical basis. Let's think about it. How much does it cost to push everything back? All the parts have to be redesigned. Is that realistic? It's not realistic. "

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

Zhang Yuan didn't know much about this aspect, but he heard it with interest.

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

It is of great significance to rebuild a complete set of industrial system with the current mathematical basis. That will make the whole new civilization more powerful, and the subsequent development will be more smooth.

It wasn't until ten o'clock in the evening that the Academic Conference on the first day officially ended. I was so tired.

Academician Ding, they have other activities. Zhang Yuan is going to walk around by himself, and then return to his residence earlier to have a rest.

There is also a receptionist at the door, who is waiting enthusiastically. She is the staff specially responsible for receiving Zhang Yuan.

"Hi, hello."

"Hello

With a shrug of his shoulders, Zhang Yuan felt a little cold. The temperature here is only ten degrees, not high. It may be to ensure that the heat emission does not exceed the standard. He didn't feel very well.

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

"Yes, in fact, our resistance and immunity will become worse. If we go back to earth, we are more likely to get sick."

"Listen to your accent..."

Coincidentally, the girl who received Zhang Yuan was also a Xia native, with a little Donghua accent in her accent.

On this alien planet, it's a tearful experience for the villagers to see each other.

"Are you from Donghua, too? Ha ha, what a coincidence! "

The girl even wanted to help Zhang Yuan with her luggage, but Zhang Yuan quickly refused. It's impossible for a gentleman to let a girl take these things.

But in this ghost place, his body is light. He feels that this thing is in his hand, and his center of gravity is a little unstable. He can't even walk."I'll do it. There's no gravity." Because she has lived here all the year round, the girl named Jin Meilin has gradually got used to the gravity of Europa, and her pace is very steady.

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

"I was only 1.65 meters old, but I was pulled down 1.7 meters alive! Girls don't need to be that tall. Every day also eat a kind of biological calcium, in order to resist the loss of calcium, good trouble

The girl turned her mouth, pointed to her thigh muscle and said, "like me, if you come here for a year, the muscle atrophy is not serious. If you stay for a long time, it will degenerate to be as soft as cotton."

Zhang Yuan said with a smile: "it's wonderful to be able to grow tall. Many boys are stuck at 1.69 meters. How eager they are to glow in 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 go back to earth, it will recover in a short time. Don't worry too much. "

Kim said with a smile: "Mr. Zhang, exercise can only slow down muscle degeneration, but not completely eliminate it. Especially the decline of the chest, it's too difficult to recover. Although, ha, it's very tall and straight in this place. After returning to the earth, it's like Yan's eggplant. It's hard to imagine... "

Zhang Yuan scratched his hair and laughed awkwardly.

He subconsciously glanced at each other's chest, well, it was really tall and straight.

Even, the buoyancy of air has been comparable to gravity, which can be said to become the most perfect shape.

However, it seems impolite to stare at him for a long time, and he won't look after a glance.

Maybe it's because it's hard to meet the villagers. They soon got familiar with each other. The girl in charge of reception was very cheerful and took Zhang Yuan to visit all kinds of equipment in the base. These devices may appear in the future.
