Academician Ding continued: "There is no 'hard work' or 'discipline' in my dictionary, only 'interest' and 'feeling of accomplishment'. Therefore, I do not limit your daily working hours and working days per week. The pressure and motivation for learning come from your own inner driving force... If you have any questions, you can ask me directly or ask your senior brother."

After pausing for a moment, 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. It is impossible to learn everything you want to learn."

Zhang Yuan thought about it carefully for a while, but he was a little confused for a while. He was very interested in every direction.

While 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 see the knowledge on the spacecraft and then consider the direction. It is always right to lay a solid foundation."

"Also, the conditions in the laboratory are so poor at present, and there are very few resources. You need to queue up for any experiment. I would recommend learning more basic knowledge unless you have a particularly good idea and then do projects, and you can also do some realistic experiments on the computer. I can help you with this..."

Gravity is now simulated by centrifugal force. For some more refined experiments, any Coriolis force is a nightmare existence.

Academician Ding nodded, "What you said is right. Zhao Qingfeng, when you have time, you can take him to the gravity-free area outside for a walk. Well... I'd just be intern in the nuclear fusion engine room for a while."

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

Zhang Yuan's heart moved and ran to the gravity-free zone outside for an internship. He must be willing.

The Earth Age's nuclear fusion engine is the most cutting-edge thing.

"By the way." Academician Ding said: "If you want to formally graduate, you must at least publish an article in a journal on the first district of the earth. The current paper evaluation system of our new civilization has not been established yet, so you can only calculate it based on the calculations on the earth, or be widely recognized by experts in the industry."

Just one paper...

As if he saw Zhang Yuan’s question, Academician Ding smiled and said, “Don’t think it’s very simple. If it weren’t for the poor conditions of the laboratory here, my requirements would be higher.”

Zhang Yuan had a sudden idea and suddenly had a question: "What if I can't publish a paper?"

Academician Ding laughed: "Either apply to drop out of school, or continue to postpone graduation, and be the first group of people who die in the stars in old age!"

...

Academician Ding is actually very busy.

Although the Earth Age has been tested for a long time, many minor problems are still exposed during the entire voyage, and some things need temporary adjustments, so these big guys cannot see a single person all day long.

In the following time, Zhang Yuan and his senior brother Zhao Qingfeng had more contact.

Zhao Qingfeng is a job at the 18th level and is responsible for maintaining the material circulation system. He is actually very busy, but the level of busyness is definitely lower than that of Academician Ding, and at least he can see it every day.

"So that's the case, the work level is proportional to the level of busyness. My original second-level position was just a sweeper. I could absent from work at will, and you won't be able to do this."

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

"Let's go, I'll take you out and have a look!"

People with work levels below 10 must report to their superiors if they want to leave the living area, and they must be accompanied by others.

"Verification is passed, please be careful!"

One of the nurse girls suddenly smiled and said, "Mr. Zhang Yuan, please do not go out for more than 10 hours each time. Otherwise, excessive calcium loss will cause osteoporosis. You can go to the hospital to buy some calcium tablets."

"Okay, thank you for your 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'm very good..."

Zhang Yuan's scalp was numb and he quickly ran away.

The two put on their space suits and walked into the elevator.

The elevator slowly rose, and as the linear speed decreased, the "gravity" that Zhang Yuan felt became smaller and smaller. At the same time, it created a dizziness of 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 of them were completely in a state of weightlessness.

The two "swimmed" into a track car with both hands and headed to the air pressure door.

Several soldiers guarded the air pressure gates. When they saw Zhang Yuan and the others, they checked their identities and saluted.

"Did~Please be careful!"

Further outside is the vacuum area.

The track car slowly started along the central axis and headed towards the first air pressure door.

Chih! A breathing sound.

After the air in this small room was drained away, we went to the second air pressure door.

The entire exhaust process was carried out in total three times before the car successfully reached the vacuum zone outside.

The most precious thing in the universe is matter. Humans do not have the ability to create a complete vacuum, so they will lose a small amount of matter every time they enter and exit, which is inevitable.

However, as long as the lost substance is within the bearable range.

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

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

Zhang Yuan thought for a while: "It is mainly to reduce the mass of the spacecraft."

Senior Brother Zhao nodded: "Yes, although the air density is low, the overall sum is an amazing number... If the mass of the spacecraft is as high as billions of tons, it is impossible to accelerate to 7/100,000 of the speed of light. Think about it, the mass of our 500,000 people is only 30,000 tons in total, which is a difference of many orders of magnitude."

The cabin is very empty and emits dim lights. Senior Brother Zhao pointed his finger out the window, "As for those complex pipes, they are actually the spacecraft cooling devices. The heat generated in the living area is brought to the outside through these condensation devices, and then circulated to dissipate heat through the radiant sails on the outside of the spacecraft."

Although the average temperature in space is more than minus 200 degrees, there is no matter exchange and the heat dissipation is extremely slow, so it can only be dissipated by radiation.

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

Senior Brother Zhao said slowly: "In fact, with the current carrying capacity of our spacecraft, it is not enough to carry 500,000 people."
