The three-dimensional image of the Earth slowly rotated in the air.

Song Jiahui stood six meters away from the holographic earth, stretched out her hand and gently plucked the earth, and as she toggled, the slowly rotating earth accelerated, stopped or reversed with her toggle.

As the person in charge of the earthquake prediction project, she took several subordinates of the sensor layout sub-project to inspect the layout of the point, and the senior brother who Achai worked for was also inside, standing second to Song Jiahui's right.

Song Jiahui spun the earth quickly and turned it into a red ball. This crucial step is about to be completed, and she is full of a sense of accomplishment.

She smiled and watched the earth spin around a few times. Then I stopped it again, and turned to the area that was still blank, and stopped for a while in each of the small areas and looked at it.

These actions are not necessary, and even for Song Jiahui and other real employees of Shengshi, the hologram of this earth is not necessary. But some habits are ingrained and deeply rooted in people's genetic code (DNA). Therefore, Shengshi still respects the habits of employees as human beings. Allow for redundant and wasteful scenarios.

In the future, people will eventually get used to the new ways and get rid of the old ones that don't work, which can be regarded as part of evolution. In the future, this kind of scene where everyone gathers to watch a virtual image should be like this, everyone lies or sits at their workstations, looks at the things presented in their minds, such as the earth full of sensors, and then communicates information in their brains. Actions are unnecessary, being together is unnecessary, and talking is unnecessary.

But now, the vast majority of employees are still accustomed to watching a virtual image to discuss it, controlling it with movement, and communicating with sound. Well, that's it!

Song Jiahui turned the earth to the Pacific region, which was empty, zoomed in, and looked at the points that had been pre-fixed and should be lit up, but had not yet lit up.

He sighed and asked, "How are the past two days?" ”

Achai's senior brother, David Lee, replied: "Just like that, full of negative energy, there is a boy under his influence, who is developing in a bad direction, and even the efficiency of the whole group is a little lower. After he came out of school, he also lowered his requirements for himself a lot, and his self-control ability was not up to standard. ”

Song Jiahui laughed and said: "They are just monitoring the operation, and they don't let him do it, so that they can bring the efficiency of the whole group to the ditch, he is really not an ordinary 'strong'." ”

Achai's senior brother David shook his head with a helpless smile.

Students or employees like Achai should have been eliminated from Shengshi a long time ago, and Shengshi has no room for them to survive. But Achai was brought back by Li Siyi, which is a fact that everyone knows.

As the center of the prosperous era, Sister Siyi, who is highly respected and loved by everyone, has never said anything about her relationship with Achai in any public setting. She didn't even explicitly or implicitly say that she brought Achai back, and before boarding the ship bound for Marna Island, she handed over Achai named Chai Song Gong Bi to the person in charge of taking the boy to the island.

But the news of 'Guess was brought by Sister Siyi' still spread among all the prosperous people.

Many people are very tolerant of Achai because they are afraid of this fact. Achai is a question for reasons that everyone knows, not to mention that Li Siyi, or even Judith Richter, the head of personnel at Shengshi, the principal and chief instructor of Shengshi Staff Training School, don't know.

A few years ago, Achai should have been cleared, but he stayed, and when it was almost time for him to leave, he didn't know which level of people were operating, and Achai was operated into a relatively simple sensor deployment job.

But he's still like this, and his poor performance is embarrassing.

But David and even Song Jiahui didn't think about kicking him out, but thought about how to make him perform better.

Perhaps this is also one of the root causes of human inferiority, which has nothing to do with the closeness of communication and connection. Now they can communicate directly with their heads, and any subordinate and low-level personnel can directly initiate a dialogue with any senior level. But the true situation of Achai has never been reported to a higher level of people for disposal.

As for Ah Chai's question, it's just too much, Song Jiahui just asked David to keep an eye on him and knock more.

Song Jiahui is more concerned about the design competition of the earthquake prediction system.

She made a special explanation to several subordinates: "Don't relax your modeling work, now the layout will be over immediately, as the designer and implementer of the entire seismic monitoring system, we should know the whole system best." We must not slacken and aim for the most precise. Don't end up doing this professionally, and use other people's spare time to make a system. ”

The three men and four women behind her all nodded in agreement.

Their uniform is quite fitted, and the biggest highlight of each person's figure is the advantage, making everyone look so capable.

In order to better realize earthquake prediction and train employees, Xiao Yelena, president of Shengshi Research Institute, launched a design competition for the earthquake prediction system. Based on the preliminary work done by the monitoring system project led by Song Jiahui, the information of the monitoring system they designed and the data collected were made public. On this basis, any employee can model the predictive system, either alone or in cooperation with others, and finally evaluate the advantages and disadvantages based on the actual results.

This has the added benefit of having many similar systems in operation in the future, and the results can be cross-compared and more reliable. The downside is that Yetana will be devoured for a long time to expand computing power.

Earthquake prediction is another new practice of Wang Xiao's assertion that everything is data.

What he is saying about this assertion is not that everything is made up of data.

It should be noted that there is no clear line between the real and the virtual. That is, there is no clear dividing line between what we think is the real world and the virtual world we live in on our computers.

The earthquake prediction system is based on this conclusion, what Shengshi wants to do is not to predict the earthquake in a few seconds or minutes, but to predict most of the major earthquakes 24 hours or even a few days in advance.

If we tell scientists outside of Shengshi about this expectation of Shengshi at present, those geologists and seismologists, they will definitely think that this is a fool's dream, either a neurotic or an international joke.

But the people of Shengshi have no objection to being able to achieve this goal. At most, it is the length of time it takes, and it makes a difference between three months and five months. Not the difference between ten or a hundred years.

The basis for this is the assertion that everything is data.

The Earth is a separate entity, and in the case of earthquakes, it is a relatively closed system. There are few extraneous factors that affect earthquakes, and the impact is not too large, which is to be expected. This creates conditions for earthquake prediction, with relatively few parameters, making it easier to build models.

Earthquakes are all caused by the release of stored forces. These forces are accumulated by external and internal forces, the internal forces are generated by the Earth's own structure, composition, revolution and rotation, and the external forces are generated by the gravitational pull of the celestial bodies in the solar system. And the gravitational pull of celestial bodies, which is mainly the force generated by the gravitational pull of the sun and moon, is eventually added to the internal force.

The movement of celestial bodies is regular and to a certain extent predictable. The internal force is unpredictable, but detectable.

There is only one accident that is difficult to detect, and that accident can be traced back to the early days of the Earth's formation. At that time, some small celestial bodies carrying substances that explode when exposed to heat crashed headlong into the interior of the earth. However, it was enveloped by a material that was not too hot, so it did not erupt at that time, and as time passed, the constant movement of these materials made these materials appear in front of the hot magma. It's like some ice that is suddenly thrown into the hot molten iron, and soon, a powerful force erupts, and this force will cause an earthquake in the depths.

The forces are continuous, except for the case of sudden outbreaks that are less than one hundredth, all other forces are continuous, and they are all gradual processes.

If you want to predict earthquakes, the first thing is to arrange useful detectors in a reasonable place. These detectors need to be able to sense small changes in force and transmit the data to the data center where Song Jiahui and the others are currently located.

Then we need to build a model of a system that can accommodate the data of these countless small changes in the Earth's interior. And use this data to generate a model of the Earth that is consistent with the reality of the Earth.

Then, the results of this earth model are compared with the actual results of the real earth, and according to the difference, the actual results of the current earth are input into the earth model of the earthquake prediction system as a new variable.

Constant correction to keep the results consistent with the actual results on the actual Earth.

The effect is that when an earthquake occurs in one place, the same magnitude of earthquake occurs at the same place on the Earth model of the prediction system.

It's like two cars parked in front of you waiting for a red light, and one behind you crashes into the car in front if it loses control. Then, it is calculable how much weight and how high the speed of the runaway vehicle needs to hit the front car in order to cause the car in front to hit the car in front of it. It is also possible to calculate the consequences of a vehicle of a certain weight hitting the vehicle in front of it at a certain speed. The result of the calculation is the inevitable result, if it is wrong, it is the lack of parameters or the wrong formula.

Such calculations are not a problem, and people have been doing it all the time to predict the outcome of many things that are currently controllable.

The most important thing is to have enough sensors that can faithfully reflect the current situation of the earth, second, to have enough computing power, and third, to have enough data that can be tested and used as a new parameter adjustment system. Of course, there must be a suitable algorithm, i.e., a model.

Enough sensors are already going to be done.

Powerful enough computing power is always expanding, and if Liu Qingsi's project is compressed enough, the expanded computing power will be enough to run a hundred such supercomputing systems in two months. But if Liu Qingsi's project is not compressed, she can devour the computing power required for such a supercomputing system in a few days, or even a day.

Song Jiahui knew that for this matter, Dean Xiao Yelena and Liu Qingsi also made trouble with Wang Xiao.

There is enough data for the Earth to provide in a timely manner, and it generates about five million earthquakes a year, many of which are imperceptible to humans, but sensors.

Now, it's a model, a system of models that can run exactly in sync with the Earth.

For the system, Song Jiahui believes that they have enough first-mover advantage, and their system has been designed before the competition began, and now it has been upgraded to the third version.

We've got to win.

Song Jiahui cheered up her subordinates and cheered herself up.
