This is the observatory you want. Pen & Fun & Pavilion www.biquge.info, Li Chen took Huang Tiansheng to the front of a wooden building. Huang Tiansheng looked up and saw that the wooden building was more than high, and there was a platform on the top, and there was a wooden shed on the platform.

Underneath the wooden shed was a round ball, which was also made of wood, but it was hollow. To be correct, it is basically a few circular wooden strips that form the shape of a circle.

The floors below were not empty, and Huang Tiansheng was very surprised to find that the things below were the same as those seen in Gaoda's room.

What is this? , Huang Tiansheng pointed to the huge circle below, as well as the bottom of the circle, and hung down.

Clock. , Li Chen said briefly, timer. Timer! , Huang Tiansheng scratched his head and turned around in circles, should this be like this? I remember a group of teachers who didn't do it like that.

Oh, that's a long story. Let's make a long story short. , grass, Li Chen's stomach is dark, isn't this what he will say when he complains about others?

You know the grapple, right? , not much. , that is, know, but not familiar. The master of the first line of the master is measured in terms of water conservancy, which is not the focus, but a stable and long-lasting measuring tool.

The following bell is ... The Law of the Bell..., oh, I see. , Huang Tiansheng suddenly realized.

The oscillator, which is the most important part of a clock, a mechanical clock. The one in charge is the work of counting. It is said that it was first invented by the Greeks, but it was not used on clocks. And the first time it was used in a clock, or a shackle, was a monk in this dynasty, a group of masters. He was a monk, an engineer, and a mathematician.

The grappling device of a group of masters is to hit the drum at one moment and hit the bell every hour. How can you turn this so fast? , Huang Tiansheng looked at the turner, and asked strangely, the principle is different. , Li Chen rolled his eyes.

He used the drip method, okay, okay, similar to the drip method, and I used the law of the bell instead. So it can be precise to a few points. There should be no one who doesn't know the law of the bell.

It doesn't make sense, it doesn't make sense. , Huang Tiansheng shook his head, led his head to the bottom of the observatory, he didn't have a single idea about timing, he didn't think it was important, in his opinion, it would be good to continue to use water power, he didn't know what Li Chen was thinking.

He is not Li Chen, I don't know what Li Chen is thinking, why do you want to spend such a lot of money, it is good to have something to use. Li Chen doesn't know him either, why did he want to cover the observatory? If you want to watch the stars, climb up to the high building in the middle of the night and observe it slowly, or do you want to build an observatory?

He didn't have too much money to burn his hands, and he didn't get the sick that money didn't cost to clean and uncomfortable. Although the income is stable, there is still no need to spend the unnecessary money. It's just that when he saw Huang Tiansheng's narrative, he suddenly changed his mind and built it.

Build it. He didn't know how good he was when he heard Gauda say that he had a way to get the observatory and could make a grapple. After Huang Tiansheng urged him to do so, and Gao Da assured him, he said let's build it. And then there was this thing.

Gauda said, "You're going to surprise me, what a surprise." , went up to the star viewing platform, Huang Tiansheng couldn't help but ask, if surprise is the big clock, I forgive you for not being sensitive.

Of course it's not that petty stuff, look. , Li Chen came up and pointed to the circle in the middle of the star observatory and expressed puzzlement, what is so good-looking? Li Chen signaled, went up to see the old one clearly.

This is!。 , Huang Tiansheng's eyes widened, and his face was full of disbelief. He stepped forward according to Li Chen's instructions, and then closed his eyes and looked out from the center of the round ball, where he used to observe the stars.

The location is a copper tube, probably to avoid light pollution, so astronomical observations are based on the control of the sky. So Huang Tiansheng is not uncommon for this point, what is there in this place.

It's just that for a moment, his eyes widened, what is this? I saw him close his eyes and look up. Because it was daytime, he didn't look at the sky, but at the ground. He held on for a moment, exhaling heavily, what was going on.

He couldn't help but be surprised, because from the bronze tube, he found that a lot of things had changed. The distance seemed to have become very short, and he was startled and looked out with both eyes, normal. I closed my eyes again and looked at the copper pipe, really, the distance between what had just been so far away had shrunk in an instant. He stretched out a hand to touch it and see if he could touch it. Don't laugh at him for being stupid, he was just shocked.

No, it's not that things have changed, it's that things have become bigger. , Soon Huang Tiansheng realized that there was something wrong with this, and then he looked into the distance, and sure enough, things became bigger, so things in the distance could be seen more clearly.

What's going on? , although he learned what was happening, he still couldn't figure out why. Does it have anything to do with this piece of glass? , He didn't turn his head to ask Li Chen, who was watching the show on the side, and silently thought about the reason.

The copper tube is not just a copper tube, Huang Tiansheng carefully observed and found several different places. First of all, there is a piece of transparent glass in front of the copper tube, and Li Chen can make the secret of glass, he has long known it, but pure glass alone will never be able to enlarge things.

Because it's round? No, it's a bulging shape. , touched the glass, he suddenly thought that Li Chen gave the children a lesson, went to optics, and taught them to use convex mirrors, which can gather light, enlarge things, and make fires.

It turned out that this was the case, and after Huang Tiansheng understood why this thing was about, he thought about the use of this thing, and he could see it farther and more clearly.

Thanks, this thing is so convenient. , Huang Tiansheng turned his head and thanked Li Chen, Li Chen was a little depressed, don't you ask why? , he originally wanted to show it, but looking at his appearance, he probably understood something.

Looking at the mirror, what Li Chen prepared for Huang Tian was the looking mirror, which was not easy to make, just the two teachers spent a month polishing the lens, and they knew how much labor it took.

Be careful, don't use this to look at the sun, or you won't be able to protect yourself with a double trick. After Li Chen warned him, he left him to play on this viewing platform by himself. He was very busy, and he was going to go out before Huang Tiansheng found him.

Master. , Li Chen went out, Wang Tian stepped forward to greet him, and more than a dozen veterans were on standby by the horse, that is, to protect Huang Tiansheng's group of veterans returned, and someone took over, otherwise Li Chen would really not be able to go out.

Let's go, we've been delayed for some time, and we're hurrying back. , Li Chen's neat horse, led a group of people, and at the highest speed that could be achieved in the city, out of Yangzhou City. Target, Mingzhou Mansion. (To be continued.) )
