In the middle of the night, it was unusually quiet in the uninhabited mountains, and on such a midsummer night, even the "buzzing" sound of mosquitoes was nowhere to be found.

High on the mountain, stands an astronomical observatory.

Antennas like giant ears, looking up at the starry sky, in this silent night, listening to the ultimate secrets of the universe that may be hidden in them.

Today is Wang Hongqi on duty, he is standing in front of the data feedback screen of the radio telescope, as in the past, he hears the sound of his heart pulsating.

He's the old man here.

Hundreds of old people of their colleagues were sent away.

He's used to the loneliness here, he's used to the namelessness here. Once, he thought he would die here, buried in this sea of stars above his head.

Before that, his only throbbing was the child, and for the sake of the child's future, he went to the capital to participate in the show Love Potato.

But when he returned to this quiet place today, he remembered the young man in the studio, and his ball.

He unscrewed the pen, and the iridium grains on the tip of the pen rubbed against the paper, making a rustling sound.

The sketching skills I learned in college many years ago are still there, and a sphere outlined with lines appears on paper.

The experts and professors who went with him didn't pay much attention to the ball, thinking that it was just a demonstration of the latest digital technology, and that it was just a gimmick.

Take the money and leave.

They came to the show, not for the truth, they were for money.

In the experiment, in the project team, it is tiring enough to bully graduate students and research dogs, why do you have to change places and repeat all this?

Wang Hongqi's primary purpose for participating in the show, although it is also for money.

However, he felt that the ball was not so simple.

It's too much like a real planet.

Its realism comes not from its visual spectacle, which seems to be spraying out of the screen, but from the abundance of detail.

You must know that even when doing astral calculations and applying for supercomputers, there are many "unimportant" parameters to discard.

Is it because they really aren't heavy either?

No, it's not, but because they're just too computationally intensive, and then because they're not that important.

Although cutting-edge scientific research may seem difficult, it is actually no different from the ideal physical world in junior high school physics books.

Because......

After all, it's still an ideal world.

However, the ball floating on the screen, with many "unnecessary" elements, is manifested.

That's what made him stand out.

Originally, he wanted to talk to the articulate young man at dinner time after the show.

But who would have thought that this seemingly cheerful young man would run away from the meal directly?

Although he also asked for his contact information from the crew, he was only good at sending emails to contact others on the Internet, and found that he couldn't use any of the contact methods registered on it.

Perhaps, for others, WeChat is already a must-have software.

However, in a place like an astronomical observatory where a microwave oven cannot be used for the sake of a pure electromagnetic environment, mobile phones are not allowed to exist at all.

And every time you log in to the computer, you have to use your mobile phone to scan the code of WeChat, obviously there is no way to use it in such an environment.

After all, there are no corded smartphones yet.

Why don't you call the young man?

Wang Hongqi glanced at the landline, began to write and draw on the paper, sorted out the questions he wanted to ask, and planned to call him during the day after the end of duty.

——————

In the night when the moonlight shines quietly.

Xue Wang didn't sleep either, but looked for a home for his mammoth head gold.

Wang Tao has promised him to create life together.

However, spiritual identity requires a material foundation.

If you don't have money, what kind of research can you do?

Therefore, he needs to cash in his mammoth head gold.

It just so happened that he had a junior high school classmate who had a gold shop at home.

It's just that...... He was a little skeptical that a gold shop could cash in so much gold quickly, but he always had to try, didn't he?

"Open the door, I'll go downstairs to your house." Zheng Peng, the young owner of the gold store, said on WeChat.

Xue Wang pressed the door of the unit, opened the door and stood at the door waiting.

"What did God mysteriously call me for? It's not clear on WeChat yet. Zheng Peng went upstairs and asked when he saw Xue Wang.

"I have a little gold, and I want to ask you how to sell it and realize it the fastest." Xue Wang lowered his voice and said, pointed to the master bedroom and whispered, "My parents are sleeping." ”

Zheng Peng also lowered his voice, tilted his head sideways like a spy and said, "Just take it to the store and sell it, what is the need to discuss." ”

"I can't hold ......," Xue Wang whispered back.

"Can't hold it? How heavy can it be? Where, let me see. Zheng Peng said with a look of disbelieving.

For Zheng Peng, who can ride a bicycle for hundreds of kilometers in a single day to buy goods, he clearly knows the weight of gold.

Even hundreds of thousands of gold didn't sink much, and even trouser pockets could be stuffed.

"Follow me." Xue Wang let Zheng Peng in, and then gently closed the door.

Xue Wang was in front and Zheng Peng was behind, and the two of them tiptoed to Xue Wang's bedroom.

Zheng Peng, who had been here more than once before, sat directly on the fabric sofa, "This is the sofa you just bought, it's a little hard." ”

"It's not a purchase." Xue Wang saw him sitting on the sofa, and he didn't know what to say, so he stopped talking.

"What's wrong? And the gold that you will show me? Zheng Peng saw Xue Wang close the door and let go of his voice a little.

"Excuse me, lift your ass." Xue Wang said

"Huh?" Although Zheng Peng was very puzzled, he still raised his buttocks.

Under the light of the white LEDs, the bright gold seemed to be shrouded in light.

"This is gold?" Zheng Peng had an expression on his face that you were teasing me.

"Hmm." Xue Wang nodded.

"It's a little little...... Zheng Peng touched such a large piece of gold, and looked up and down again. Take out the knife in the mouth of the key, dig out a small piece from it, place it on the windowsill, and burn it against the outer flame of a windproof lighter, and it turns red at a rate visible to the naked eye.

After turning red, Zheng Peng took away his not-so-cheap lighter.

I saw that the little bit of metal quickly faded red and changed back to its original appearance.

Zheng Peng picked up this small metal particle that had become a little rounded because it had melted slightly, looked at it and said, "Real gold is not afraid of fire, and the purity is still very high." If the purity is not high, it will not be so fast to conduct heat just now, it will not turn red so quickly, if there is a magazine in it, it will also be because of the different melting points, and when it solidifies again, you can see that there are fine metal particles and impurities in it.

Although the exact purity is not known, it is ...... You sent it.

How do you want to monetize, I'll help you figure it out. ”
