Chapter 1451 I'm Back
"Yes, it is the ingenious combination of convex and concave lenses of different materials that creates a compound lens. The achromatic astronomical telescope we are about to use will allow us to observe clearer images. This is the beauty of compound lenses .Besides that, we have a very important project this year." The dean of the Academy of Astronomy said two things to be announced before.

One of the things is the most important thing for the Astronomical Academy. Their Astronomical Academy will build a new observatory at the southern foot of Yanshan Mountain, and secondly, there is a project they want to carry out.

"What project?" The students of the Academy of Astronomy couldn't help being surprised.

"According to the calculations of some of our professors, a rare astronomical phenomenon-the transit of Venus will occur this year! This is a good opportunity for our Astronomical Academy to observe and record. This time we need to make detailed records for future generations An important observation data. If you miss this observation opportunity, you will not be able to see the transit of Venus again for at least 60 years! That is to say, this may be the only time in your life to see the earth, Venus and The sun appears in a straight line, please be sure to be present." The dean said.

After being told by the dean, almost all the students of the Astronomical Academy became excited.

For ordinary people in ancient times, the change of stars may be a sign or warning from heaven. In the West, Mars symbolizes the God of War. In ancient China, it was called "Yinghuoxing", which is often associated with disasters and unknowns.

But for the students of the Department of Astronomy, this is a good opportunity to witness and observe astronomical phenomena with their own eyes!

The transit of Venus that occurred this year was the last transit of Venus in the 17th century.

The so-called transit of Venus means that Venus moves between the sun and the earth, and the three are exactly in a straight line. At this time, people can see Venus passing the sun like a small black dot with the naked eye.The record of the phenomenon of Venus transiting the sun is actually recorded in the "Five Stars" in the Western Han Dynasty.

"Our Astronomical Institute seems to have got a sufficient budget, and we actually want to build an astronomical station and produce new astronomical telescopes at the southern foot of Yanshan Mountain."

"The southern foot of Yanshan Mountain is still quite a distance from the urban area, about 100 to 200 miles. We may go there to conduct observation work in the future. Thinking about it, it is really inconvenient, and we need to take a carriage. Astronomical Station The best place is of course in the mountains, but it’s too inconvenient.”

"Venus transits the sun. It is said that the process lasts for six hours. We can use astronomical telescopes to observe through some special methods. This time we are lucky. The ancients used to observe with naked eyes. Compared with us, we don't know how lucky we are. gone."

"Some professors in the college claim that the distance between the earth and the sun can be calculated through this transit of Venus, but they don't know how to calculate it."

After the dean announced the dissolution, the students of the astronomy department were still discussing the two major events announced by the dean.

The astronomical station was established, and some astronomical phenomena began to be observed and studied. The field of astronomy began to separate from serving agriculture and politics, and gradually became a separate science!

Selina was particularly excited. During the time when Li Jinde was away, she could only rely on her daughter and her studies to distract herself. How exciting it was for her to observe the phenomenon of Venus transiting through the astronomical telescope .

In this era when they are still arguing about the geocentric theory or the heliocentric theory, they have already started the research on extraterrestrial bodies!
"Selina!"

When she walked out of the astronomical institute, she found Princess Sophia waving at her with joy.

Next to Sophia, there are women who have known her, such as Ella, Da Yuer, Xiao Xiuer, Liu Rushi, etc.

"Why are you here?" Selina didn't know why.

"Hee hee, we want to visit your home." Princess Sofia said mysteriously.

"Of course you are welcome, but why?" Selina was completely confused by them.

"We want to see Yinger." Xiao Xiuer also had an intriguing smile.

Selina saw that the girls seemed a little abnormal today, and couldn't help but feel a little inexplicable, but the other girls were unwilling to tell her what happened.

"Hee hee, let's go to your house!" Princess Sofia almost pulled Selina to speed up her pace, as if she wanted to see something interesting.

"Your Highness, you must pay attention to your behavior..."

"What princess, I'm Sophia now, let's go!"

"Princess Sophia, you see that Sarina is not in a hurry yet, why are you even more anxious?" Da Yuer pursed her lips and smiled.

"I want to watch a show..." Princess Sophia pouted, still holding Selina.

Selina didn't know what the girls were going to do, but when she was almost carried back to her home by Princess Sofia, she gradually discovered something unusual.

Many acquaintances on the streets of the mansion looked at her.Some people planned to come up to say hello to Selina and tell her something, but the ferocious Princess Sofia stared those people away with her eyes, for fear that they would disturb her fun.

Li Jinde's mansion was busier than usual at this time, and the noise inside could be heard from outside.Normally, there are usually only a few women inside, so it is impossible to be so lively.

"Why do you think we dragged you back from the Astronomical Institute in such a hurry?" Princess Sophia stopped dragging Sarina this time, but stopped in front of her, staring at her with a sly smile. As if wanting to see the change in the expression on her face.

Princess Sofia was not disappointed. Selina seemed to have thought of something. Her originally calm expression became surprised, then joyful, and finally mixed with surprise. She held Princess Sofia's hand, her tone trembling: "Could it be..."

"You guessed it right." All the girls said almost in unison.

"Ah, don't lie to me! I have to go in quickly... No, is there a small mirror?" Selina originally planned to bypass Princess Sofia and enter the house directly, but then she thought that her complexion at this time must be very bad , so asked anxiously.

At this moment, a familiar and long-lost figure appeared in front of her.

The man felt strange when he heard the movement outside, so he carried his daughter out of the house. When he saw Selina, the two of them were almost stunned.

"I'm back." Li Jinde thought up a lot of words on the way back, but when he saw Selina, there were only a few words left in the thousand words.
