The Science Fiction World of Xueba

But these words cannot be said by Pang Xuelin now.

He's just a fifteen-year-old high school student, and nobody cares what he thinks.

Not to mention, all of this is nothing more than his guess, and it will happen in the end, and he is not sure.

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

At the beginning, when Pang Xuelin came up with his own ideas, the principal and Yang Zhihe disagreed.

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

However, they made a request that Pang Xuelin must continue to participate in the National High School Math League on behalf of the school before he can let him go.

Xi Pang Xuelin agreed.

I got Jiangcheng Middle School, and then Pang Shaoan took Pang Xuelin to Jiangda University.

With Pang Shao'an's relationship, it is not too simple to want to have a hearing in Jiangda.

In particular, after Pang Xuelin took out his middle school grade results and various award certificates, he was responsible for receiving the vice dean of the School of Materials Science and Engineering. As long as Pang Xuelin can enter the national training team in the next National High School Math League, Jiang You can directly enroll in special colleges, and you don't need to participate in the college entrance examination.

Pang Xuelin didn't care too much about this, and his scores in other subjects were not bad. When he took the college entrance examination in the real world, he took 728 (total score 810), which is more than 20 points higher than the Qingbei score line. If not Because of his grandpa's relationship, he would never choose Jiangda.

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

The material science major has a lot to learn, and basic courses need not be said. Physical chemistry, materials chemistry, analytical chemistry, organic chemistry, polymer chemistry, material physics, material mechanics ... Each course requires a lot of energy.

Xi Pang Xuelin found a curriculum for the undergraduate course of materials major, listed the class time of each major class, and then made his own study plan.

With Jiang Da's hearing card, you can participate in the experimental class, you can apply for a library card and a cafeteria meal card. Except that you cannot take the exam to obtain credits, Pang Xuelin is just like an ordinary Jiang University student.

Also, there are computers in the library. Pang Xuelin can access the Internet here to get all kinds of information.

Next, Pang Xuelin first rode Yao Bingxia to school every morning, and then went to Jiangda University. If there was no class in the morning, he would appear in the library on time, and wait until the end of the afternoon to pick Yao Bingxia home.

Xi Pang Xuelin seems to be back in the previous high school era. There are endless books and unfinished exercises every day.

He is grateful for the study habits that Grandpa has cultivated for him since childhood. Good study habits combined with hard work, Pang Xuelin's name quickly spread to the teachers of the School of Materials.

Almost every class of teachers encountered scenes in which Pang Xuelin stopped asking questions after class.

Naturally, they don't hesitate to answer this hard-working boy.

Pang Xuelin is like a dry sponge, eager to absorb all aspects of material science knowledge.

Although most of his energies have been devoted to mathematics these years, the foundation of physics and chemistry is there, coupled with many years of learning experience. Therefore, Pang Xuelin quickly gained a more systematic understanding of materials science.

At least about the papers on flying blade materials and graphene aerogel metamaterials, he has been aggressive from the beginning, and now he can gradually see the doorway.

Uh ...

Two months passed in a flash.

In September, Pang Xuelin participated in the national high school math competition exam on behalf of Jiangcheng Middle School, and was unsurprisingly awarded a full score, and was successfully selected into the China High School Math Olympic Winter Camp.

I just waited for the winter camp to open in December, and it's still early.

And Pang Xuelin has also decided not to go to the winter camp and training team. Anyway, he just goes through various exercises every day, which does not make any sense to him.

As for how to get the teachers of the winter camp to agree, it will not be a problem, just take a few sets of IMO papers, spend a little time to finish them, and throw them in front of each other.

In the past two months, Pang Xuelin also got a deeper understanding of this era.

Because of the sun crisis, the science and technology tree of this world seems to be crooked.

This is a highly developed world of heavy industry.

Heavy industry accounts for more than 90% of GDP.

Engineering technology has reached its peak, otherwise, there is no way to create a behemoth like a planetary engine.

In addition, metallurgy, energy, aerospace and other fields are also extremely powerful, and energy need not be said. Light nuclear fusion and heavy nuclear fusion technologies have completely broken through. The energy density of batteries has reached 6.8 kWh / kg, which is almost the real world. Twenty times.

即使 But even then, before the planetary engine was launched, humans still had a problem of insufficient energy.

With 12 thousand planetary engines, the construction cost of each engine is as high as one trillion US dollars.

最 The most important one is the problem of raw materials.

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

行星 A planetary engine ~ www.readwn.com ~ More than 90% of its main structure is made of steel. The mass of each planetary engine is as high as 500 million tons, which can burst nearly 15 billion tons of thrust. (Note: There are loopholes. Under normal circumstances, such a thrust cannot push the earth away from the solar system, but in the original work, it will not be changed.)

With a total of 12,000 engines and dungeon, it almost exceeds the limit that human industry can reach.

逃 In order to escape the solar system and to survive under this starry sky, this desperate race has burst into unimaginable power.

五十 In addition to the elderly, children and students, more than 90% of the world ’s five billion people are directly or indirectly serving the construction of planetary engines.

In the past 30 years, the coalition government has mobilized the whole nation at all costs and has smashed all resources into the construction of planetary engines.

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

不够 If there is not enough iron ore on the earth, go to the moon to dig. If the moon is not enough, humans will send a spacecraft to the asteroid belt to find a metal-rich asteroid. After finding it, install an engine on it and transport it back to earth.

The remaining electricity can only barely guarantee electricity for 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 computer phones are too expensive for ordinary people to reach.

Therefore, the world in the field of microelectronics is not much different from previous generations. Materials science is also strong in metallurgy and other fields, and there are almost no breakthroughs in the field of non-metallic materials.

Graphene has barely produced energy, but it is difficult to be satisfactory regardless of its purity and cost.
