Chapter 1816 Huge Ice Lake

Chapter 1816 Huge Ice Lake

A good astronomer must be a mathematician. Because all astronomical discoveries rely on mathematical calculations. In fact, this is not only true in astronomy, but also in many scientific fields.

Therefore, mathematics is called the jewel in the crown of science. A person who wants to devote himself to science must be a person who likes mathematics. If you have no interest in mathematics, then you don't even want to be a scientist. '

Zhao Zhongyao looked at Feifei and said again about how this Ceres was discovered. After hearing this, Feifei also felt very miraculous.

‘Dad, it seems that this Ceres is really amazing. is an asteroid discovered by a mathematician. There must be many magical things on this asteroid. ’ Feifei said again.

‘Of course, we just want to go to this asteroid to have a look. Zhao Zhongyao said again.

However, Zhao Zhongyao thought about what he said just now, and thought about other things, so he looked at Feifei again and said, 'Actually, even the children who are in school now are like this. When a child is young, he can see whether he can become a good child in learning in the future.

How can you tell! It is to see if the child has an interest in mathematics. If a child is very interested in mathematics from an early age, he can certainly become a child who learns very well. If he has little interest in learning, he is unlikely to be a very good student.

In the world of academic masters, there are no students who are poor in mathematics. And among the children who are poor in learning, there are no children who are good in mathematics. Generally speaking, whether a child can learn well depends on whether he can learn mathematics well.

This is the case in school. Mathematics has occupied a very important position from the very beginning. Whether you are in primary school or college. Mathematics is the key to determining whether you can be admitted to a good university and find a good job.

The best university in the country, the best major is inseparable from mathematics. Only children who are good at mathematics can enter the best majors in prestigious schools. If you are not good at mathematics, it is of no use even if you enter a prestigious school. Because you can only be in the ordinary class, you can't enter the experimental class at all.

So, for a student, want to study well. We must learn mathematics well. Only by learning mathematics well can you enter a good university, enter an experimental class, and have a good job after graduation. '

When Zhao Zhongyao said this, Feifei nodded and said, 'Yes, the reason why I can study well is because I have been interested in mathematics since I was a child. '

The reason why Zhao Zhongyao was able to become a famous military scientist. Also because of his good mathematics. The reason why Feifei and Tiantian were able to get into a good university is also because of their excellent math scores.

Even when Qu Yuqian was in school, her math scores were very good. Otherwise, it would be impossible for her to become Zhao Zhongyao's classmate. It is impossible for the two of them to go all the way to today.

After Zhao Zhongyao heard Feifei's words, he looked at Feifei and said, "Do you think mathematics is very important?" '

Feifei smiled and said, "Of course it's very important. Isn't it because we are all masters of mathematics that we can now soar in space and travel and explore places that others would never come to in their lifetime!" '

After hearing Feifei's words, Zhao Zhongyao said,'Yes, it is because we are masters in mathematics that we are able to explore space. '

Just when Zhao Zhongyao was talking like this, he found that his spaceship had flown near Ceres, had been captured by Ceres' gravity, and was flying towards Ceres.

‘Okay, we’ll be on Ceres in a minute. Zhao Zhongyao said so.

Sure enough, a bright star could be seen outside the huge porthole of the spaceship. At this time, the spaceship is still several million kilometers away from Ceres. From this distance, Ceres is just a bright star in space.

However, these millions of kilometers may be nothing to the flying saucer spacecraft, and they can fly there in just a few minutes.

Soon, the spacecraft flew over Ceres. Now the spacecraft is only a few thousand kilometers away from Ceres. At this distance, you can really see what Ceres looks like.

Ceres is a very special asteroid located in the asteroid belt. It is the largest asteroid among asteroids. But it is the smallest asteroid among the dwarf planets.

Ceres is a round asteroid. It may be because of its relatively large size, under the action of gravity, such asteroids will have a relatively round shape.

The asteroids smaller than Ceres, such as Vesta, Juno, and Pallas, have very irregular shapes. Because their volume is only half that of Ceres.

Due to their small size, the gravitational pull is relatively weak. It is also impossible to keep yourself in a spherical shape, basically all irregular shapes. There are also some other asteroids in this asteroid belt. As long as they are asteroids with a volume of less than 500 kilometers, their shapes are generally irregular spherical.

‘Dad, is the shape of this asteroid still relatively regular and spherical? ’ Feifei said looking at the huge planet full of craters outside the porthole.

‘That’s right, Ceres has a diameter of more than 900 kilometers, almost a thousand kilometers. It is already considered a dwarf planet, and its shape will of course be spherical. Zhao Zhongyao said again.

‘Dad, then we should go to that place on Ceres to look for amethyst gems now! you

It doesn't mean that there must be an amethyst gemstone on Ceres, which is the fifth amethyst gemstone we are looking for. ’ Feifei said again.

Zhao Zhongyao thought for a while and said, 'If you want to talk about this Ceres, it is really amazing. So scientists speculate that Ceres is a water planet, and there may be a lot of water on Ceres. Up to 40% of the volume on Ceres may be composed of water.

But the water on Ceres exists underground. On the surface, there is no water, only a layer of lithosphere. If we want to find water on Ceres, we can only find it in some relatively large craters.

In a crater with a diameter of about 80 kilometers on Ceres, astronomers once saw some bright things in this crater. They speculate that these things may be water ice.

We're looking for the fifth amethyst gem, and we don't have to look elsewhere. We can go directly to the fifth crater. If I guessed correctly, this fifth amethyst gem is in the No. 5 crater of Ceres. '

After hearing Zhao Zhongyao's words, Feifei said happily, 'Okay, then we don't have to look for it elsewhere, let's go directly to this No. 5 crater! '

So, Zhao Zhongnian drove the spaceship and went directly to find the No. 5 crater. Although, they already have a goal. But it is also difficult to find a crater on this asteroid with a diameter of nearly 1,000 kilometers.

Fortunately, they are now more than a thousand kilometers away from the surface of Ceres. At this altitude, the entire surface of Ceres can be seen. Even some relatively large craters on Ceres can be seen clearly.

In this way, Zhao Zhongyao drove the spacecraft and flew around Ceres. At this time, the flying saucer spacecraft is almost equivalent to an artificial satellite flying around Ceres.

Since the spacecraft also has very advanced detection equipment, Zhao Zhongyao and the others can clearly see the entire surface of Ceres while sitting in the spacecraft.

Although this No. 5 crater is not the largest crater on Ceres. But in this crater, there is a very mysterious phenomenon. It is at the bottom of this crater that there is a white reflective material.

These reflective substances were first discovered by some astronomers. But they don't know what those white substances are.

However, they speculate that these things are water ice, the groundwater of Ceres, which was melted from the ground due to the impact of meteorites and rushed out of the surface, and then formed a lake. But because Ceres is very far away from the sun. The surface temperature is very low, and these lakes will freeze to form water ice soon after overflowing the surface.

With the help of the advanced detection instruments and equipment on the spacecraft, Zhao Zhongyao quickly found the luminous crater on Ceres, which is the famous No. 5 crater.

'Okay, we found this crater, we can go to this crater. When Zhao Zhongyao saw this crater from the display of the spacecraft, he said this with interest.

But Feifei, Tiantian and Qu Yuqian cannot be seen from the porthole. After all, they are now more than a thousand kilometers away from the surface of Ceres. The surface of Ceres cannot be seen clearly with the naked eye.

It’s just that when Feifei heard what Zhao Zhongyao said, he also said happily, ‘Dad, can we go to this crater? '

‘That’s right, we’ll land right into this crater. After Zhao Zhongyao finished speaking, he drove the spaceship down to this crater at an extremely fast speed.

Soon, the spacecraft driven by Zhao Zhongyao landed above this crater. Now the spacecraft is only a few hundred meters away from the crater. From this height, you can observe the situation inside this crater without instruments.

‘Dad, there’s a frozen lake down here! ’ Feifei has already seen clearly the situation under the No. 5 crater.

At this time every day, she also saw the situation under this crater from the porthole, and she also looked at Zhao Zhongyao and said, Dad, there is water on Ceres. '

At this time, Zhao Zhongyao also saw the situation at the bottom of the crater. Everything is still as in the legend, there is really a frozen lake at the bottom of the No. 5 crater. And it is also a very huge ice lake. After all, it's impossible for a probe to see it tens of thousands of kilometers away if it's not very large.

‘It’s good to have water, there may be life if there is water, and there will be amethyst gemstones if there is life. The amethyst gemstones we are looking for are all in places with life. And there should be life under this huge lake. Zhao Zhongyao said again.

'Dad, what are you waiting for, let's go to this icy lake to have a look. ’ Feifei looked at the huge icy lake below, and wanted to go to see it for himself.

Zhao Zhongyao also said at this time, 'Of course we have to go below to have a look, but we can't land directly on the ice. Who knows how thick this ice layer is, if it is not thick enough, it will not be able to bear the weight of our flying saucer spacecraft. If the spaceship falls into the water, it will be more troublesome. '

After hearing what his father said, Feifei said disapprovingly, "Dad, what are you afraid of? Isn't our spaceship an amphibious spaceship of land, sea and air!" We don't have to worry about it falling into the frozen lake. '

After hearing Feifei's words, Zhao Zhongyao smiled and said, "Feifei, you are right, our spaceship can sail underwater." But you need to know that this is Ceres. This is not an ocean on Earth. If our spaceship lands on the ice and breaks the ice, the spaceship will fall under the ice.

And the surface temperature here is very low. If the spaceship fails to fly out in time after it falls, the ice may freeze quickly. If that is the case, it will be more troublesome. '

After hearing Zhao Zhongyao's words, Feifei nodded and said, 'Dad is still thoughtful, but I didn't think so much. It seems that we still can't land directly on the ice, we still have to land on the lake first. '

‘That’s right, let’s land by the lake first! This is relatively safe. We must first observe how thick the ice layer of this icy lake is in the spacecraft. Zhao Zhongyao said so.

After finishing speaking, Zhao Zhongyao drove the spaceship again and flew towards the lake. The area of ​​the entire glacial lake is very large, and the diameter from one side to the other may be more than ten kilometers.

Zhao Zhongyao drove the spaceship from above the middle of the ice lake to the shore on one side of the ice lake. Then, he drove the spaceship and landed carefully to a place tens of meters away from the icy lake.

When the spaceship stopped, Zhao Zhongyao observed the surface outside again. He saw that this place was full of large and small rocks. These rocks were very similar to the rocks on Pallas, that is, some rocks with speckled black background and yellow spots.

Feifei looked at the speckled rocks in front of him and said, 'Dad, are these rocks the same as what we saw on Pallas? Is it also some carbonaceous grain rock. '

After hearing Feifei's words, Zhao Zhongyao nodded and said,'Yes, these rocks should also be some carbonaceous grain rocks. '
