The Science Fiction World of Xueba

But Pang Xuelin couldn't say these words now.

He is just a fifteen-year-old high school student, and no one will care what he thinks.

Not to mention, all of this was just his speculation, and he wasn't sure if it would happen in the end.

Early the next morning, Pang Shaoan and Pang Xuelin came to Jiangcheng Middle School and found the principal of Jiangcheng Middle School and Pang Xuelin's class teacher Yang Zhihe.

At first, when Pang Xuelin expressed his ideas, the principal and Yang Zhihe disagreed.

But when Pang Xuelin easily completed several sets of IMO competition test papers and got full marks in all of them, they had nothing to say.

However, they made a request that Pang Xuelin must continue to represent the school and continue to participate in the National High School Mathematics League before he can be let go.

Pang Xuelin readily agreed.

After finishing Jiangcheng Middle School, Pang Shaoan brought Pang Xuelin to Jiangda University.

With Pang Shaoan's relationship, it shouldn't be too easy to get a witness in Jiangda University.

In particular, after Pang Xuelin showed his middle school achievement certificates and various award certificates, the deputy dean of the School of Materials Science and Engineering who was in charge of receiving them immediately made a decision. As long as Pang Xuelin can enter the national training team in the next National High School Mathematics League, Jiang You can directly enroll in special admissions, and you don't need to take the college entrance examination.

Pang Xuelin didn't pay too much attention to this, and his grades in other subjects were not bad. When he took the college entrance examination in the real world, he scored 728 (total score 810), which was more than 20 points higher than Qingbei's score line. Because of his grandfather, he would not choose Jiang University at all.

The next thing he has to do is to show his abilities as quickly as possible, lay a good foundation, and then find a suitable time to take out the flying blade material and graphene airgel supermaterial.

Materials science majors need to learn a lot, not to mention basic courses, such as physical chemistry, material chemistry, analytical chemistry, organic chemistry, polymer chemistry, material physics, material mechanics... Each course requires a lot of energy.

Pang Xuelin found the curriculum schedule for the undergraduate course of the material major, listed the class time of the professional courses one by one, and then made his own study plan.

With Jiang University's audit pass, he can participate in experimental classes, and can apply for a library card and canteen meal card. Except that he cannot take the exam to obtain credits, Pang Xuelin is no different from ordinary Jiang University students.

Moreover, there are computers in the library, through which Pang Xuelin can surf the Internet and obtain all kinds of information.

Next, Pang Xuelin drove Yao Bingxia to school every morning, and then went to Jiangda University. If there was no class in the morning, he would show up in the library on time, wait until the afternoon class was over, and then drop by to pick Yao Bingxia home.

Pang Xuelin seems to have returned to the old high school days, with endless books and exercises every day.

He is very grateful to his grandfather for the study habits he cultivated since he was a child. With good study habits and hard work, Pang Xuelin's name quickly spread among teachers in the School of Materials Science and Technology.

The teachers of almost every class have encountered the scene of being stopped by Pang Xuelin to ask questions after class.

For this studious boy, they naturally spared no time to answer.

Pang Xuelin is like a dry sponge, eagerly absorbing all aspects of materials science.

Although most of his energy has been devoted to mathematics in recent years, the foundation of physics and chemistry is there, coupled with years of learning experience, so Pang Xuelin quickly gained a relatively systematic understanding of materials science.

At least for the papers on flying blade materials and graphene airgel metamaterials, he has been stunned from the beginning, and now he can gradually see the way.

...

Two months passed by in a flash.

In September, Pang Xuelin represented Jiangcheng Middle School in the National High School Mathematics Contest and got a full score without any surprises.

Successfully selected for the Chinese High School Mathematics Olympiad Winter Camp.

It's just that the winter camp won't start until December, and it's still early.

Moreover, Pang Xuelin has already decided that he is not planning to go to the winter camp and the training team. Anyway, going there is just doing exercises every day and various trainings, which is meaningless to him.

As for how to get the teachers of the winter camp to agree, this is even less of a problem. You only need to take a few sets of IMO test papers, spend a little time to finish them, and throw them in front of the other party.

In the past two months, Pang Xuelin has gained a deeper understanding of this era.

Because of the sun crisis, the technology tree of this world seems to be a little crooked.

This is a world with highly developed heavy industry.

Heavy industry accounts for more than 90 percent of GDP.

Engineering technology has reached its peak, otherwise there would be no way to create a giant like a planetary engine.

In addition, metallurgy, energy, aerospace and other fields are also extremely powerful, not to mention energy, light nuclear fusion and heavy nuclear fusion technology have been completely broken through, and the energy density of the battery has reached 6.8 kWh/kg, which is almost the same as that of the real world. twenty times.

But even so, before the planetary engine is activated, human beings still have the problem of insufficient energy.

With 12,000 planetary engines, the construction cost of each engine is as high as tens of billions of dollars.

The most important of these is the issue of raw materials.

Even Pang Xuelin couldn't believe it when he saw the relevant data.

More than 90% of the main structure of a planetary engine is made of steel. The mass of each planetary engine is as high as 500 million tons, and it can explode nearly 15 billion tons of thrust. (Note: There is a loophole here. Under normal circumstances, such a thrust cannot push the earth away from the solar system, but this is the case in the original book, so it will not be changed)

A total of 12,000 engines and dungeons almost exceeded the limit that human industry can achieve.

In order to escape from the solar system and continue to survive under this starry sky, this desperate race exploded with unimaginable power.

Of the 5 billion people in the world, except for the elderly, children and students, more than 90% of the remaining human beings are directly or indirectly serving for the construction of planetary engines.

For thirty years, the coalition government has mobilized all the people at all costs and poured all resources into the construction of planetary engines.

Ninety percent of the electricity generated by nuclear fusion power plants is used for the construction of planetary engines.

There is not enough iron ore on the earth, so they dig on the moon. If there is not enough on the moon, humans send spacecraft to the asteroid belt to find metal-rich asteroids. After finding them, they install engines on them and transport them back to the earth.

The remaining power can only barely guarantee the power consumption of large fully enclosed farms and people's livelihood.

For example, private electric vehicles that consume more power are strictly prohibited. Even ordinary electronic products such as computers and mobile phones are so expensive that ordinary people cannot afford them.

Therefore, this world is not much different from the previous life in the field of microelectronics. Materials science is also strong in metallurgy and other aspects. There are almost no major breakthroughs in the field of non-metallic materials.

Graphene is barely energy-produced, but its purity and cost are unsatisfactory.
