The Science Fiction World of Xueba

Pang Xuelin found the way to climb Mount Everest.

After more than a thousand days and nights, and more than three years of uninterrupted thinking and research, he finally touched the edge of the number theory universe.

The hard ice layer began to shatter and melt, and the deep prime number structure hidden under the ice layer gradually surfaced.

The frame system of Far Abelian geometry has been completely smashed and reorganized by him, and a new set of mathematical theories is quietly brewing.

If you hear the Tao in the morning, you can die in the evening!

An unprecedented sense of joy welled up in his heart. Pang Xuelin closed his eyes, opened his arms, and embraced the starry sky.

This is a long-lost joy.

The last time I felt this kind of happiness was when Pang Xuelin proved the André-Oort conjecture under the condition of polarized Abelian clusters.

But the level of pleasure couldn't be compared with this time.

As for the BSD conjecture, let alone, it has nothing to do with Pang Xuelin at all.

In these years, the reason why Pang Xuelin was able to embark on the path of mathematics academics as his grandfather wished, and became a full professor of Jiangcheng University at a young age, was only because he felt that mathematics research was simple and happy, especially the kind of research that explored the truth. Pleasure cannot be replaced by anything.

Thanks to Mars, thanks to this quiet and desolate world, he can really calm down and think about some essential things.

In the real world, even at Jiangda University, Pang Xuelin is likely to be affected by various pressures, and it is difficult for him to have the opportunity to calm down and think about a proposition that is unlikely to produce results for three years.

He might not even have thought of doing such unpopular research on Far Abelian geometry.

But here, he succeeded.

A whole new world of mathematics has been opened by him, waiting for him to explore.

Far Abelian geometry, no, perhaps more accurately, it should be called Ponzi geometry.

Pang Xuelin absorbed the essence of far Abelian geometry, and carried out drastic reforms to its framework system. It can not only accurately describe the similarity between the addition structure and the multiplication structure, but also describe the nature of the power.

This is a brand-new mathematical system, and it is well-deservedly named Ponzi geometry.

And Pang Xuelin faintly felt that next, as long as he slowly fills this theory with flesh and blood and fills up various loopholes, then not only can the ABC conjecture be perfectly solved, but even Goldbach's conjecture, twin prime conjecture, hail conjecture and other number theory fields The well-known problems are all within the scope of its solution.

But now, this theory is still quite immature, and Pang Xuelin has only thought of a preliminary framework structure, and he has no way of predicting how long it will take him to complete this theory.

Regrettably, in more than a month, my long journey to Mars will come to an end.

At that time, no matter whether it is in the Martian world or in the real world, I am afraid that I will not be able to study as hard as I did in the past few years.

...

One month later, the Ares 4 mission team successfully arrived at Mars. With the help of Pang Xuelin's habitat, the members of the Ares 4 mission team conducted a one-month investigation on Mars.

As a veteran who has lived on Mars for many years, Pang Xuelin naturally accompanied these rookies all the way and participated in scientific expedition activities.

Subsequently, Pang Xuelin and the Ares 4 mission team took the MAV (Mars Ascension Vehicle) to the Hermes.

After nearly a year of flight, Hermes returned to Earth smoothly and docked with the International Space Station in geosynchronous orbit.

Inside the space station, waiting for Pang Xuelin was Watney who hadn't seen him for a long time.

After reminiscing about the past, Pang Xuelin went through a few days of physical examination and adaptation in the space station to ensure that there were no problems before returning to Earth on a synchronous orbit shuttle.

The shuttle landed slowly on the airport, and he was greeted by a sea of ​​people, with applause and cheers like a tsunami everywhere.

With a smile on his face, Pang Xuelin stepped out of the shuttle and set foot on the ground.

At the same time, the long-lost voice of the system rang in Pang Xuelin's ear: "The mission is completed, and the evaluation is in progress... The evaluation is completed, and the completion of this mission is S. Congratulations to the host, you have obtained the Astronaut's Eye. In addition, the system will randomly select a technology as a reward."

A huge lottery interface instantly appeared in front of Pang Xuelin. The lottery roulette was divided into six areas, each representing six technologies.

The six technologies are:

1. The ion engine on board the Hermes.

The engine has a power of 1.5 megawatts and uses argon atoms as fuel. After the argon atoms are ionized, the on-board nuclear reactor provides a strong electromagnetic field and ejects them at high speed, giving the Hermes an acceleration of 0.2 meters per square second. The engine can be used for planetary system travel and is the best power source for planetary system spaceships.

2. High-power radioisotope nuclear battery (RTG)

At present, the total power (including electric power and thermal power) of the most advanced radioisotope nuclear battery in the world is at the level of one hundred watts, and the electric power is about four to five watts. The nuclear battery of the Mars Rescue plane reaches the kilowatt level, the thermal power exceeds 1600 watts, and the electric power reaches the hundred watt level. It is an artifact of power supply for unmanned space vehicles.

3. Oxygenator molecular sieve

The super carbon dioxide absorber has special physical and chemical properties. As long as enough power is provided, it can continuously absorb the carbon dioxide produced by human respiration and convert it into oxygen. It plays an extremely important role in the fields of manned spaceflight and deep space exploration.

4. The combined engine carried on the earth orbit shuttle.

The engine adopts the combination of turbojet + sub-combustion ramjet + scramjet + rocket engine, which can make the aircraft freely shuttle between the atmosphere, adjacent space and geosynchronous orbit, and is an artifact for human beings to fly in near-Earth space.

5. Flexible metamaterial airgel

The material is a three-dimensional graphene airgel macroscopic body, which can exhibit the excellent properties of graphene materials at the macroscopic level, such as up to 99% recoverable compressive superelasticity, a wide range of adjustable Poisson's ratio characteristics, high electrical conductivity, stable The piezoresistive effect and ultra-low thermal conductivity play an important role in the fields of aerospace, flexible actuators, flexible robots, sensors, deformable electrode materials, drug delivery and delivery, ultra-light heat insulation and protective materials.

6. MDV (Mars Landing Vehicle)

The soft landing technology on the surface of Mars has always been one of the most important problems for manned landing on Mars. MDV uses the combination of parachute and rocket engine to enable eight astronauts to land safely on the surface of Mars. This equipment is of great significance for human manned interplanetary exploration.

...

Pang Xuelin glanced over the six sectors on the roulette one by one. Compared with the last trip to the Three-Body World, the rewards provided by the system on the Martian plane this time are basically practical engineering technologies. And most of them are manned spaceflight, whether it is high-power ion engine, radioisotope nuclear battery, oxygenation machine molecular sieve, or combined engine, flexible metamaterial aerogel, MDV, all have important significance for human aerospace engineering.

However, in comparison, the high-power ion engine and the combined engine on the shuttle are more valuable. The former is suitable for human interplanetary deep space exploration, and the latter has more practical significance.

Since the retirement of the US space shuttle, the current human space vehicles are still dominated by rockets, and it is difficult to change in the next ten or twenty years.

The emergence of this combined engine can bring the era of aerospace aircraft decades ahead of schedule, and it is very attractive to any country.

In comparison, the other technologies are not so significant.

"System, let's draw a lottery!"

Pang Xuelin said lightly.

The roulette began to spin rapidly, and a minute later, the roulette pointer stopped on the flexible metamaterial aerogel.

"Congratulations to the host, the acquisition of metamaterial airgel and related preparation processes."

"call……"

Pang Xuelin can't say how disappointed he is. Compared with the strategic weapon that combined engines can enhance a country's aerospace capabilities, metamaterial aerogels are undoubtedly much weaker.

But even if he gets a combined engine, how to explain its origin is a big problem for the country. This kind of metamaterial aerogel with excellent money prospects is a good choice.

"Host, the lottery is over, you can choose to stay in the Martian rescue plane for one to two years, or you can directly return to the real world!"

"Go straight back to the real world!"

Pang Xuelin sighed and said.

As a hero who has lived on Mars for more than 1,700 days, even if Pang Xuelin stays on the plane of the Martian rescue, he will not be able to be quiet in the future.

What is waiting for him is probably various endless activities and interviews, as well as being bestowed with various honors.

It meant nothing to him.

Anyway, he has already met Watney, and he has fulfilled his biggest wish in the Martian world.

"Goodbye, Watney!"

"Goodbye, Mars!"
