Chapter 104

Seeing that it was getting late, 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.

The conference room was crowded. He found academician Ding and sat down properly.

Academician Ding sent him a document and said, "this kind of academic conference has been discussed for 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 the report 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 self-confidence. He has long been familiar with that paper. Let him recite it backwards.

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

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

Academician Ding came to the stage and talked freely.

"... for a simple example, in the field of machining, constructing second-order smooth spline surfaces on surfaces with complex topology has always been a very important central problem..."

"... we have made very long-term development in machinery manufacturing, automobile and aviation industries. Scholars and engineers have made great efforts to construct smooth spline functions on manifolds. However, the result is not ideal. There are always singular points with poor smoothness of splines. "

"Can this problem be solved?"

"The answer is, No."

"It has been mathematically proved impossible."

There was a whisper in the conference room, and Zhang Yuan thought.

It was the first time he had heard these views. It was very interesting.

Academician Ding continued, "why not? Because the original industrial system was wrong. "

"The traditional spline construction methods, including spline theory, have irreparable defects, which makes the natural promotion of traditional splines to manifolds futile no matter how hard future generations try."

"For the specific certification process, you can read the following materials..."

"... I have read historical materials and found that the original scholars did not care about this problem. The original industry was not developed enough, and the processed parts were all quite simple, so there was no need to consider too many complex mathematics. When the original engineers established the whole standard, they were not aware of the possible technical crisis hundreds of years later... "

"The instability of the industrial base has directly killed the upper limit of the whole civilization. Our current industrial system has become stable, and it is impossible to start over because of the instability of the theoretical basis. Let's think about it. How much will it cost to push everything back? All the parts have to be redesigned. Is it realistic? Unrealistic. "

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

Zhang Yuan didn't know much about this, but he still heard it.

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

Using the current mathematical basis to re-establish a complete set of industrial system is a very meaningful thing. That will make the whole new civilization stronger and the subsequent development will be more smooth.

It was not until ten o'clock in the evening that the Academic Conference on the first day officially ended. It was very tired.

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

There is also a receptionist at the door who is waiting warmly. She is a staff member 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, not high. It may be to ensure that the heat emitted does not exceed the standard. He doesn't feel very well.

The girl said, "your ship has a constant temperature of 24 degrees all year round, and its cold resistance is not very good. Human beings, as long as they don't use things, will quickly degenerate. "

"Yes, in fact, our resistance and immunity will become worse. 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 a Xia nationality, and even had a Donghua accent.

On this strange planet, when villagers see villagers, they are almost tearful.

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

The girl even wanted to help Zhang Yuan with her luggage, but Zhang Yuan quickly refused. A gentleman can't 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 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, "people here are generally taller. Is it because of low gravity that the bones have been elongated... How tall were you?"

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

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

Zhang Yuan smiled: "it's great to be tall. Many boys stuck at 1.69 meters are eager 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 return to the earth, you will recover in a period of time. Don't worry too much. "

Kim Merrill Lynch smiled and said, "Mr. Zhang, how can you imagine that exercise can only slow down the degradation of muscles, 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 an eggplant. It's hard to imagine... "

Zhang Yuan scratched his hair and smiled awkwardly.

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

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

However, it seems impolite to stare at it for a long time. I don't look at it after glancing at it.

Maybe it's because it's rare to meet fellow villagers. They get familiar with each other soon. The girl in charge of reception was very cheerful and took Zhang Yuan to visit various equipment in the base. These devices may also appear in future parent stars.
