“…… Recently, China's manned landing office encountered a sudden sandstorm during a scientific expedition to Mars, resulting in a scientific researcher losing contact during the mission. ”

"After learning of the situation, the ground command center immediately organized rescue work, using a number of equipment, including low-earth orbit optical observation systems and unmanned reconnaissance vehicles, to carry out emergency rescue work for the missing personnel."

"The entire rescue work lasted five hours and 27 minutes, and finally succeeded in rescuing the missing people."

"According to the person in charge of the Mars scientific research base, at that time, the researcher entered the nearby mountain range in order to avoid the sandstorm, due to the special landform and geographical environment of Mars, the electromagnetic wave signal attenuation coefficient is large, which has a great impact on the normal use of communication, positioning and other equipment, which has caused serious safety accidents......

"More details are still under investigation."

"CCTV reporter, report for you."

Lunar Research Station.

Sitting in the public cafeteria and watching the news projected on the LCD screen, Sun Lieyang, who was eating, frowned.

"I don't know if it's my delusion."

"What delusion?"

"I always feel like this news is going to be the end of the story."

Pinch the head and remove the tail?

Raising his eyebrows with interest, Tao Muye stopped the chopsticks in his hand.

"You mean, there's more to it than that's been revealed?"

"Yes," nodding, Sun Lieyang said simply, "You have been trained." ”

"Everybody here has embraced it."

"The third article in the safety manual, I remember very clearly, in the event of a space accident caused by force majeure, you should wait for rescue in place unless necessary."

"Maybe it's necessary."

"Do sandstorms on Mars count?"

After hesitating at this rhetorical question, Tao Muye shook his head.

"I don't know...... After all, I haven't been to the site either. ”

"I always felt a bit far-fetched."

With the ultra-low air pressure on Mars, a dust storm is not a very big threat at all.

Hiding in the nearby mountains to escape a sandstorm, and then nearly losing contact due to a communication failure caused by the hematite veins in the mountains, it is like a person jumping into a nearby river to avoid the rain, but this person is also a planetary geologist.

This is no longer a joke about one's own life, it's just how to die.

Although Sun Lieyang also understands that life is full of accidents, his intuition tells him that there must be something hidden here.

"Whatever, even if there is another hidden truth in taking 10,000 steps back, it is not something we should know. Let's eat melons with peace of mind," re-moving the chopsticks, Tao Muye smiled and said, "I estimate that the people on the ground command center are only afraid of a cold sweat at this time, but fortunately the people have found it, otherwise this plan will be cold after just two steps." ”

Although he is still a little concerned, Sun Lieyang also agrees with Dr. Tao's point of view in his heart. Even if there is another hidden secret, it has nothing to do with these scientific researchers on the moon.

Looking at Dr. Sun, who had picked up the chopsticks to eat again, Tao Muye smiled and diverted the topic.

"Speaking of which, how is your second-generation controlled fusion research going? A little bit of progress, no. ”

Sun Lieyang replied casually.

"Yes, everything in my dreams."

“……”

……

Originally, in Lu Zhou's plan, the unified theory of algebra and geometry was his final work in the field of pure mathematics.

At least until he hits the all-subject grade to LV10, he probably won't put his focus back on math unless he encounters a problem that interests him in particular.

The first is to leave some opportunities for latecomers.

Second, he really can't be busy.

In addition to mathematics and physics, which has reached the full level, there are as many as five disciplines that need to be mastered, and these disciplines are all disciplines with long research and development cycles and large randomness that focus on application fields.

Especially when the research involves specific application scenarios, this is not something that can be solved by finding a pen and sitting in the study and casually calculating.

However, life is always full of surprises.

It's like he never thought he'd be involved with the Void again in this form......

"Why did you suddenly think to come to me?"

School of Mathematics, Jinling University,

Looking at Lu Zhou, who walked into his office, Professor Perelman, who was sitting at his desk writing something, stopped the pen in his hand and cast an inquiring glance at him.

"There's a question I can't think clearly, I heard that you're still here, so I came over......" Walking in from the door, Lu Zhou glanced around the slightly messy office, smiled and greeted, "Speaking of which, aren't you going back to St. Petersburg?" ”

"I'll probably be here for a while until Hodge's conjecture is resolved," Perelman turned his pen to answer the question succinctly, "I'm more curious about what is stumbling you than these inconsequential things." May I start by asking if it's mathematical? ”

"It's mathematical."

Walked to the sofa and sat down, Lu Zhou nodded with a smile to the assistant who brought the tea, then looked at the mist rising from the cup, and continued in a soft voice, "To be precise, it's ABC conjecture." ”

The pen in his hand fell on the table.

Perelman frowned.

ABC conjecture...... How did you get interested in that thing? ”

"Because of curiosity," Lu Zhou thought for a moment and said vaguely, "as well as some practical reasons." ”

"Is it related to the working meeting of Jinling University some time ago?"

"Work meetings?"

"Well, I heard from the other math professors here," Perelman frowned and continued, "Recently, you seem to be concentrating on tackling the ABC conjecture, and it seems that you have offered a reward of 100 million or how many scientific research funds?" In fact, with all due respect, this kind of problem cannot be solved by a large number of people and a large amount of money. ”

Is there such a thing?

Lu Zhou was stunned for a moment, and then smiled dumbly.

"I don't know, maybe someone did something superfluous...... However, this conjecture does have a bit of an important idea for us, do you have any good ideas? ”

Perelman: "I've read Shinichi Mochizuki's paper. ”

"I've seen it too...... So? ”

"Then you should know what I'm trying to say," Perelman muttered, then continued, "If the Riemann conjecture is the Everest of mathematics, then the ABC conjecture is the cloud floating next to Everest, which is undoubtedly a mathematical problem, which can be described in very concise mathematical language, but it is not like a problem that mathematics can solve." ”

"Professor Mochizuki's work is equivalent to creating a special mathematical language that is parallel to mathematics itself...... Anyway, his far-abelian geometry seems to me to be such a thing. ”

"To put it bluntly, the biggest difficulty in solving this problem is that no one in the mathematical community today has really done more than 'useful' research on this problem. If you really want to look into this problem, you'll have to redefine the whole math in the same way that you redefine addition and subtraction. ”

"Could it be easier for alien math to solve this problem...... Perelman muttered, "of course, that's just my guess." ”

This sentence made Lu Zhou subconsciously tense his nerves.

However, he soon realized that Perelman was just talking casually, and it didn't look like he knew the inside story.

Thinking of this, Lu Zhou's expression couldn't help but become a little subtle.

It's a bit tricky.

At present, the high-level is still discussing the issue of whether to make the "fifth type of contact" public, and if it is finally made public, will today's conversation make this old friend feel that he is playing tricks on him?

But after thinking about it, Lu Zhou quickly left this matter behind.

For such a scholar who is obsessed with mathematics, even if he understands the inside story behind this, he probably won't be interested.

"Redefining the language of mathematics in the same way that it redefines addition, subtraction, multiplication and division?" With a thoughtful expression on his face, Lu Zhou stood up from the sofa, "I'll go back and think about it." ”

Without making any reservations, Perelman nodded and said.

"If I have any new ideas, I'll talk to you again."

"Actually, I'd rather discuss this issue with Shinichi Mochizuki or Schultz, who seem to have a lot of research on this issue."

Lu Zhou nodded.

"I'll think about it."
