The Science Fiction World of Xueba

On the radio, Wen Carter's voice continued.

"Guys, I know this news is quite surprising, in fact you do n’t have any psychological burden. We discovered the anomaly of the Asidalya Plains campsite through a satellite photo about a month ago, and after a month of hard work, Finally got in touch with Pang and Watney. In the process of communicating with the earth, they repeatedly emphasized that this incident was only an accident, your approach was correct, and they don't blame you. And you may not know it, Watney He Pang also planted potatoes on Mars, and now they are the first humans to carry out agricultural activities on an alien planet, or they are the pioneers of human colonization on Mars. "

"At present, the Ares Command has developed a comprehensive rescue plan. We will rescue Pang and Watney at all costs, so please rest assured that it won't be long before you can see Pang Hewo on earth. Turnie. Also, if you have anything to say to Pon and Watney, you can send it to Houston, and I will convey it for you! "

Soon after, Friedrich, Baker, and Gross also came to the gravity chamber.

"Where is Colonel Lewis?"

Baker asked Haruko Kitagawa.

"I'm here!"

I do n’t know when Colonel Lewis, who has a red circle under his eyes, returned to the gravity chamber. She looked at her team members softly and said, "Guys, let's discuss how to write to Pang and Watney!"

Uh ...

Mars, Plain of Athedaria, Mars at 9:30 PM.

In the perch, Pang Xuelin was lying on the bedside, listening leisurely to a jazz CD that Watney found from personal belongings left by Colonel Lewis.

Watney was sitting in front of the computer, chatting with the expert security team outside the light.

Of course, most of the time, their content is nonsense.

Since connecting with the earth, the control of Ares Command has become stronger than ever. It is as big as Pang Xuelin and Watney ’s overall plan in the next few years, and as small as the nutritional mix of each meal, they will sell. Intervention.

For example, Pang Xuelin and Watney found that the water circulation system's water output rate had decreased to a certain extent, and they thought that the water circulation system was clogged. They were ready to repair it by themselves, find the blocked pipeline, and clean it up.

After ten hours of discussion, the expert committee rejected the proposals of Pang Xuelin and Watney.

They think that this kind of work can only be done by professionals. At present, the water circulation system can still be used. There is no need to repair the water circulation system at the risk of breaking it.

So Pang Xuelin and Watney happily put their suggestions behind their heads, and spent a day to disassemble the water circulation system, find the clogging point, clean it up, and then reassemble it back without any problems.

Of course, the expert team is not without some effective suggestions.

For example, fine-grained management of crops will increase the carbon dioxide content of the planting cabin, thereby increasing the amount of organic matter synthesized.

Another example is to use an oxygenation machine to fill up the liquid oxygen storage tank, just in case of a crisis, insufficient oxygen content, etc.

At this time, Pang Xuelin and Watney also relaxed, and now they can do almost the same, and then just wait patiently for the first season of potato harvest.

On the advice of the expert team, most of the time, they will stay in the habitat, reduce the number of EVA, and thus reduce the consumption of carbon dioxide absorbers.

Originally, the two kept busy every day in order to survive, but now all of a sudden, Pang Xuelin felt a little uncomfortable.

While listening to music, he wondered if it was time to find a suitable research topic for himself.

I was thinking, and Watney in front of the computer suddenly called out, "Pang, come here, Lewis. They wrote us an email, which was just forwarded by Houston!"

Pang Xuelin quickly got up from the bed and came behind Watney.

Watney opened the email and read it.

"Dear Pon, Watney, it's nice to hear that you are still alive. Really, really, each of us is very happy. I now especially regret that I shouldn't give up on you, I should treat you The situation is fully responsible. Now Sergey, Kitagawa Haruko, Baker, Gross, and Friedrich are all by my side. They miss you so much. As long as you need it, all members of the Hermes will provide you at any time. Help, I hope we can help you. The Ares Command has told us that they have a practical rescue plan, and I believe you and Pang will be able to survive on Mars with your own wisdom. Wait You return to Earth, and I invite you to drink.—Lewis and Hermes members. "

"Pang, let's write a reply to Lewis!"

Pang Xuelin smiled, "Of course!"

Soon, Pang Xuelin and Watney worked out a new e-mail and responded back.

"Colonel Lewis and dear teammates, hello everyone, I'm glad to be able to hear from you again. Pang and I had a good time in the Asidalya Plain. Without you, the space for the habitat is much more comfortable. The incident was just an accident, and our bad luck led to today's situation. Colonel Lewis's order was completely correct. This is a decision that is responsible for the safety of other people's lives. May all of you go home safely and look forward to returning Have a drink with you after the earth. — Pang Xuelin, Watney. "

Uh ...

Time passed day by day, Pang Xuelin and Watney's life on Mars became boring and monotonous.

Every morning, Watney will enter the planting cabin, check the air composition in the planting cabin, loosen the potatoes, test the humidity of the soil, and then decide whether to increase the moisture content of the soil.

Sometimes he also adds some newly processed pure natural fertilizers to the soil.

Pang Xuelin checked the operation of various systems in the habitat, recorded log data, and sent it back to the earth, and performed regular maintenance on certain equipment according to the recommendations of the expert committee.

It has been more than three months since the specific Pang Xuelin entered the Martian rescue world. The potatoes in the planting chamber have grown to 20-30 centimeters high and one piece of green oil can be harvested in half a month.

他们 When they returned photos of potatoes to the earth, it caused a huge sensation.

To this end, Watney had to cooperate with Ares Project Command to give a popular science Mars botany course to the children on Earth.

Xi Pang Xuelin has relatively little life. He finishes recording and maintenance every day, and there are still five or six hours left to arrange freely, so he gives himself a new subject-to prove the ABC conjecture.

The ABC conjecture is an important conjecture in the field of number theory. It was proposed by Joseph Oesterlé and David Masser in 1985 ~ www.readwn.com ~ hence the Oesterlé–Masser conjecture.

The mathematician Goldfield once said: "The ABC conjecture is the most important one of the unsolved problems of Diophantine equation!"

French mathematician Lucien Szpiro (mainly engaged in number theory, arithmetic algebraic geometry, and commutative algebra) tried to overcome this conjecture in 2007, but it was proved to be wrong.

In August 2012, Mochizuki, a mathematician at Kyoto University in Japan, published a more than 500-page dissertation, introducing his comprehensive generalization of the Tichmuller theory, and claiming that this theory can be used to prove several aspects including the abc conjecture. A famous conjecture, but this obscure theory has not been accepted by the mathematical community.

Xi Pang Xuelin had read Wang Yuexin's dissertation while reading, but did not understand.

According to his mentor Tao Zhexuan, the proof-of-concept part of Mochizuki's new one is too complicated. The first three hundred pages of the thesis are almost all establishing a new mathematical system. The key is that this system can only be used in very few areas such as the ABC conjecture. Get applied.

In contrast to Mochizuki Shinichi, Zhang Yitang and Perelman gave a concise "proof of concept" at the beginning of the dissertation, and the methods they developed can also be quickly applied to the corresponding field, obtaining some interesting non-trivial new results. , Or a new proof of some non-trivial conclusions already given.

Therefore, such a behavior that complicates a simple problem is usually a mistake.

Xi Pang Xuelin naturally did not want to prove the ABC conjecture at one breath. If it is difficult, this conjecture is not much simpler than the BSD conjecture.

He just wants to have some fun for himself, after all, life on Mars is too boring and tedious.
