"With all due respect, even if you can use an astronomical telescope now, you can't see anything, you can't use an astronomical telescope to see the sun!" Li Nan Kan Jidong looked longing, and he couldn't help but roll his eyes.

In broad daylight, use a yarn astronomical telescope, and now there are no special landscapes such as sunspots, so you can't just use the sun filter to watch the sun.

And it's summer, who knows if the solar filter of the astronomical telescope here is good or not? If it doesn't explode, wouldn't it be miserable?

However, these problems that Li Nan is worried about are not a problem, there are no conditions here, they don't know if the staff can still not know? If it is something that cannot be done, the staff will definitely stop it.

For Li Nan and other students who like to run around, a student ID card is an indispensable thing, after all, as long as you hold a student ID, there are discounts no matter where you go.

So after strolling around below for a while, the two went upstairs with their student IDs.

Except for the entrance of the building, there is a person who is responsible for checking the student ID reception, and there is no one else guarding here. Walking up, you can find that the top is really empty, compared with the bottom, it is really very empty.

Only a few students were visiting.

Li Nan swept his eyes and found that this side was indeed quite fresh and refined. There weren't any models of galaxies, no images of the starry sky or anything like that, just a large projector on the opposite wall of the room, and the projector was filled with pictures of the stars.

There are also dedicated docents and machines that can manipulate the contents of the projector in real time.

"Why do you have to make a second floor with these things, and only students can come in?" Li Nan was really puzzled when he saw it, and thought that there were some more precious things on it, but it turned out that it was necessary for a large projector and a few commentators to make such trouble?

Ji Dong's feeling should be similar to Li Nan's, where the things on the second floor look like a planetarium, it is no problem to say that it is an astronomical science and technology lecture.

"Of course I'm happy!" said a person on the side who looked like a docent, but the tone was not at all, and he said with a smile.

"You are the eldest son of Ji Laohu's family, I didn't expect to meet you here, I also drank your full moon wine!"

Ji Dong looked at the middle-aged man talking across from him in a bit of a daze, but he was still unimpressed, and he didn't know how this person knew him.

"Sorry, are you?"

Zhao Yuhuai pushed his glasses, walked a few more steps to their side, and said with a smile: "It's no wonder that you don't know me, I only met you once on the day of your full moon, and I haven't actually met since then."

But I've seen your photos, and your dad often posts photos of you and your sister in his own space!

You can call me Uncle Zhao, your father and I are old classmates, if it weren't for the different majors we applied for in college, maybe we could be classmates for more than ten years. ”

"Uncle Zhao is good!" the corners of Ji Dong's mouth twitched slightly, and he exclaimed a little embarrassed.

To be honest, sometimes it feels better when you meet a stranger, but it always feels more embarrassing to meet an elder who should be familiar but is not familiar with herself.

"This is your classmate, originally the third floor was not open, come, today I will take you up to see and see.

Don't leave at night, I'll invite your dad to drink when the time comes!" Zhao Yuhuai said with a smile as he beckoned Ji Dong and them to the third floor.

Li Nan's sense of embarrassment at this time was actually stronger than Ji Dong's, because Ji Dong still had something to do with him, and Li Nan really didn't know him at all. Some wanted to push away, but they were too embarrassed to say it directly, so they could only follow them up to the third floor in the end.

The third floor and the second floor are completely different scenes, and the third floor can be said to be an astronomical research institute, which may be a bit inappropriate to call it an astronomical research institute, but at least it can be said that it has something to do with astronomy.

There is a glass platform on one side, and there is a space above the platform, which should be a group of astronomical telescopes. The rest of the place is densely packed with things, including special storage cabinets for chemical drugs, as well as large and small, almost small granular whole meteorite specimen cabinets. There is even a laboratory bench that covers an area of about ten square meters.

On the whole, it doesn't look like a person specializing in astronomy, but it feels like astronomy is just a hobby, and he should be a researcher in medicine or chemistry.

Li Nan could know what the use of these chemical agents was with a sweep of his eyes, and he immediately understood that he should do some replacement reactions of special components in meteorites here.

Although not all meteorites are useful and have elements that are not found on Earth, there must still be some rarer meteorites that have elements that are not found on Earth, or extremely rare elements on Earth.

That's what he's doing here.

Generally speaking, however, this kind of thing is rarely done by private individuals, because the cost of doing it is too high, and it is difficult to get enough samples.

Speaking of which, we have to talk about the price of meteorites, ordinary meteorites, meteorites that do not have any particularities themselves, the price of meteorites is not high, you can buy hundreds of thousands of them, cheaper, or illiterate, thousands of them can be bought.

But the more precious, especially the meteorites that have been detected, contain some special mineral components inside, can not be sent by three melons and two jujubes, the most important thing is that this kind of thing will rarely be bought and sold, and many countries will be forcibly purchased by the country's scientific research institutions.

As a result, the price of private buying and selling will naturally rise higher and higher. And as long as human beings have not been able to explore the planets at will in the galaxy and bring back the materials on the planets, then the price of this meteorite will not fall, but will only rise and not fall.

Although I don't know why the meteorite specimens on his side can be so comprehensive, it is definitely expensive.

"Uncle, what's the use of you doing these elemental replacement reactions? Even if there are some results, it is difficult to do anything on your own!

Even if some of the elements in it are replaced, they basically don't have much effect when the country is not able to carry out space travel in an all-round way!" Li Nan watched the man surnamed Zhao constantly introduce how noble his work was, and he couldn't help but say.

Zhao Yuhuai listened to Li Nan's words and glanced at Li Nan deeply, not that he was dissatisfied with what Li Nan said, but he felt that Li Nan seemed to be quite far-reaching.
