Deep Space Fleet

Academician Ding continued: "There are no 'hardship' and 'discipline' in my dictionary, only 'interest' and 'sense of accomplishment'. Therefore, I do not limit your daily working hours and the number of working days per week. The motivation comes from your own inner driving force... If you have any questions, you can ask me directly, or you can ask your brother."

After a pause, he asked again: "By the way, what kind of research do you want to engage in? Space industry is just a big major, and there are many subdivisions in it. You want to learn everything, but it is impossible to learn came here."

Zhang Yuan thought about it seriously for a while, and he was a little dazed for a while. He was very interested in every direction.

When he was thinking, Senior Brother Zhao suddenly said: "If you don't have a particularly complete understanding of the entire space industry, you can first experience it on the spaceship, and then consider the direction. It is always right to lay a good foundation."

"Moreover, the current conditions of the laboratory are really poor, and there are very few resources. Any experiment needs to be queued. I still recommend learning more basic knowledge, unless you have a particularly good idea, and then do the project, you can also use it on the computer. Do some simulation experiments on the Internet, I can help you with this..."

The current gravity is simulated by centrifugal force. For some more delicate experiments, any Coriolis force is a nightmare.

Academician Ding nodded, "That's right. Zhao Qingfeng, when you have time, you can take him to the non-gravity area outside. Hmm...just practice in the nuclear fusion engine room for a while."

"The nuclear fusion engine is by far the most complicated project. If you figure out the entire workflow, you can basically graduate."

Zhang Yuan's heart moved, and he ran outside to the zero-gravity zone for practice. He must be willing.

The nuclear fusion engine of the Earth Age can be described as the most cutting-edge thing.

"By the way." Academician Ding said again: "If you want to officially graduate, you must at least publish an article in a journal in the first area of ​​the earth. The current paper evaluation system of our new civilization has not yet been established, so we can only follow the paper evaluation system on the earth. calculation, or to be generally recognized by experts in the industry.”

Just one essay...

As if seeing Zhang Yuan's question, Academician Ding said with a smile, "Don't think it's easy. If it wasn't for the poor laboratory conditions here, my requirements would be higher."

Zhang Yuan had a whim, and suddenly had a question: "What should I do if I still can't publish the paper?"

Academician Ding laughed: "Either apply to drop out of school, or postpone graduation all the time, and be the first batch of people who die of old age in the starry sky!"

...

Academician Ding is actually very busy.

Although the "Earth Age" has been tested for a long time, many small problems were still exposed during the entire voyage, and some things needed temporary adjustments, so these big guys never saw a single figure all day long.

In the following time, Zhang Yuan and his brother Zhao Qingfeng got in touch with each other more.

Zhao Qingfeng is an 18th-level job, responsible for the maintenance of the material circulation system, and is actually very busy, but the level of busyness must be lower than that of Academician Ding, at least he can see him every day.

"It turns out that the level of work is directly proportional to the degree of busyness. My original second-level position was a sweeper. You can absent from work at will, but you can't."

Zhao Qingfeng said with a smile: "No, I don't need to take care of it all day long. It's just that it's the initial stage of the voyage, and there are more temporary adjustments."

"Go, I'll take you out to have a look!"

Those whose job level is lower than level 10 must report to their superiors if they want to leave the living area, and must be accompanied by other people.

"Verification passed, please pay attention to safety!"

One of the nurses suddenly smiled and said: "Mr. Zhang Yuan, please do not go out for more than 10 hours each time. Otherwise, you will lose too much calcium and you will easily become osteoporosis. You can go to the hospital to buy some calcium tablets."

"Okay, thanks for the reminder."

Another nurse laughed and said, "Wang Shuo, why do you have such a good service attitude today? Do you like him very much?"

"Where is it? I was fine..."

Zhang Yuan's scalp was numb, and he hurried away.

The two put on their spacesuits and walked into the elevator.

The elevator rose slowly, and as the linear speed decreased, the "gravity" felt by Zhang Yuan became smaller and smaller. At the same time, there is a feeling of dizziness standing in the "drum" of the washing machine.

Finally, when the elevator reached the central axis of the spacecraft, all the dizziness disappeared, and the two were completely weightless.

The two "swim" into a rail car with their hands and head to the barometric door.

Several soldiers were guarding the air pressure doors. When they saw Zhang Yuan and the two, they checked their identities and saluted.

"Drip~ Please be careful!"

Further outside is the vacuum area.

The rail car slowly moves along the central axis, heading for the first gas pressure door.

Chi! There was a gasping sound.

After the air in this small room is evacuated, it goes to the second air pressure door.

The entire pumping process was carried out 3 times before the car successfully reached the outer vacuum area.

The most precious thing in the universe is matter. Humans do not have the ability to create a perfect vacuum, so small amounts of matter are lost each time they go in and out, which is unavoidable.

However, as long as the lost material is within the acceptable range.

Along the way, Zhao Qingfeng kept introducing various facilities and equipment in the zero-gravity zone.

"Do you know why there is no air in the zero-gravity zone?"

Zhang Yuan thought for a while: "The main reason is to reduce the mass of the spacecraft."

Senior Brother Zhao nodded: "That's right, although the air density is low, the overall sum is a huge number... If the mass of the spacecraft is as high as several billion tons, it is impossible to accelerate to 7/1000 of the speed of light Think about it, the mass of our 500,000 people is only 30,000 tons in total, a difference of many orders of magnitude."

The interior of the cabin was empty, with dim lights. Brother Zhao pointed his fingers out of the window, "As for those complicated pipes, they are actually spaceship cooling devices. The heat generated in the living area is carried outside through these condensation devices, and then circulated and dissipated through the radiation sail on the exterior of the spaceship."

Regardless of the fact that the average temperature in space is more than two hundred degrees below zero, there is no material exchange, and the heat dissipation is ridiculously slow, so it can only be dissipated by radiation.

As an important part of the ecosystem, heat dissipation can be said to be the top priority of the spacecraft.

Brother Zhao said slowly: "Actually, the current carrying capacity of our spaceship is not enough to carry half a million people."

Zhang Yuan was taken aback for a moment, they half a million people, don't they live well?
