    Although the secret base is located in the mountains and forests, due to the specially chosen terrain, the lighting conditions here are very good. During the day, students attend classes and absorb the spiritual power of the sun for practice. At night, Yunyang absorbs the power of the stars, or leads students to observe  Stars, teaching astronomy knowledge will not be affected.  "First of all, we can confirm that the spiritual power of the sun and the power of the stars will have huge energy after being mixed. It can be used as a bomb, relying on violent explosions to kill the enemy. So of course, if we can control its energy release smoothly, we  Can we use this energy to do more things? For example by installing it on a vehicle, can we create a bicycle that does not rely on human power or animal power, but relies solely on mechanical power?  So, can we install it on a windmill, rely on this energy to drive the windmill to rotate, and finally create a flying instrument, so that ordinary people like us who have not been promoted to the extraordinary realm can also fly in the air like the masters of the extraordinary realm?  ? And if the soldiers gain the ability to fly, will we gain more advantages and reduce casualties better when fighting monsters siege cities and flying monsters? " " Or, we will?  Having created instruments that can automatically operate on the synchronous orbit of the ancestor star, can we rely on these instruments flying in the sky to spy on enemy intelligence, or even directly attack ground targets from space?  ” Yunyang described one wonderful prospect after another.  Because Yunyang had previously discussed the concept of orbit, the students could already understand that when the speed reaches a certain level, it will be suspended in space and will not fall down.  But what Yunyang was describing at this moment still exceeded the limit of their imagination.  "Self-propelled vehicle? Flying instrument? This, this is too incredible." "This is indeed incredible, but as long as we continue to study, we will eventually achieve our goal." Yunyang smiled confidently  Laughing: "This is exactly the purpose of me selecting thirty of you into the science class through selection. We are doing something unprecedented. If this thing succeeds, each of us will be remembered in history. Every one of us will go down in history."  Everyone will become a hero in the history of the human race Now, follow me and start acting together. " Yunyang is not proficient in mechanical operation, and what he knows is only what he heard before.  But this did not stop Yunyang from starting to study them.  So what if you're not proficient?  Yunyang just needs to know that those things exist. As for the specific manufacturing plan these students are not stupid. Those in the previous life can study it, why can't the students here study it?  Although Yunyang is not proficient in mechanics, he roughly knows that no matter what he is doing, he needs an engine, and the task of controlling the smooth output of energy needs to be achieved by this engine.  But before that, Yunyang still has many things to do.  "I need everyone to explore ways to smoothly output energy based on the experience accumulated in the previous development of solar bombs" This is a very important scientific research task in the near future.  In addition to this task, Yunyang also needs to teach these students various astronomical knowledge.  "This is Kepler's three laws about the laws of planetary motion. Well, I found the celestial records recorded in our Shenghua City for nearly a hundred years. From this record, we can actually conclude that Kepler  Kepler's three laws come. With Kepler's three laws, we can accurately predict the movement of planets. It should be pointed out that different star systems will have different Kepler's constants.  "Constant, but within the same star system, such as our solar system, Kepler's constant is certain and will not change." "Relying on previous astronomical knowledge to determine the distance between the earth and the moon, or the distance between the sun and the earth will be somewhat different.  It's difficult, but after learning Kepler's three laws, all this is no longer a problem. You can try it yourself after class. If you really measure the distance between the earth and the moon or the sun and the earth, I will give you a reward.  You. But if measured by Kepler's three laws, this reward will not be becoming a disciple of Senior Brother Zhao Ke. " "Look, that is Vega, it is a very bright star. Now I need you.  Think about how to measure the distance between it and the earth. Let me give you a hint. Our ancestral star is orbiting the sun. If we take this moment as the starting point, our ancestral star will orbit the sun in half a year.  On the other side, since the position of the ancestral star has changed, it is observed that the position of Vega in the sky will definitely change. Then we connect the different positions between the two ancestral stars as the bottom edge, and then connect Vega to form a  Triangle, we can calculate the distance to Vega through relevant calculations of trigonometric functions"  "Today we are going to learn some knowledge about optics. You may have noticed that there is always a certain error in the depth of water when looking through the water surface. When the chopsticks are placed in the clear water in the bowl, the chopsticks will bend.  , this is the refraction of light, and the water surface can be used as a mirror, which is the reflection of light. At the same time, the magnifying glass will expand the image, and the reducing mirror will shrink the image. This is also a part of optics that we need to learn and master.  With this knowledge, we can build a telescope. Through the telescope, we can see scenes hundreds of millions of kilometers away" "Today we will learn about the material composition of stars and the related knowledge of different elements in the spectrum.  Different colors of light will be emitted at the same temperature. After dividing the mixed light into separate lights through optical instruments, we can determine the elemental composition of distant stars by analyzing the light of different colors. We will know that the sun is just one.  It's just a big fireball, and it's also made up of some very common elements" "Today we're going to learn some basic knowledge of physics and chemistry. Why do copper and iron rust? Why do cut apples turn brown?  There are countless kinds of substances in the world, but what is the most fundamental connection between them? " Yunyang is almost relying on his own efforts to construct the scientific foundation for this world.  Yunyang's major is astrophysics, with concurrent studies in astrometry and celestial mechanics, and he also has certain attainments in observational astronomy.  But apart from astronomy, I only have a very general understanding of other aspects of physics, chemistry, mechanics, etc.  Most of the time, Yunyang just proposed a rough idea and started it, and then let the students continue to study it on their own.  Because in other aspects, Yunyang really didn't have much to teach them.  But even so, after about two months of being stationed in the secret base, Yunyang finally led the students to produce the first scientific research result.  That was a telescope, a very ordinary Galilean telescope.  In his previous life, Galileo used this telescope to observe Jupiter and distinguish the four satellites of Jupiter and the Great Red Spot on Jupiter.  Its lens barrel is made of wood and its lenses are made of water ice.  In order to maintain the condition of the telescope, Zhao Wei had to inject energy into it every one or two days, otherwise the lenses would melt.  After this telescope was built, the students saw the true face of Jupiter for the first time with their own eyes, and also saw the four satellites that are constantly orbiting Jupiter.  Under the current conditions, being able to see those four satellites is already the limit.  Jupiter has dozens of large moons, but in comparison, they are still too small to be observed by telescopes.  "It's true! The Sui Star is really just a big ball of gas. What are the stripes on it? Is it a storm? Why is there such a strong storm on the Sui Star?" "That's the Sui Star's moon! There are four full  There seems to be a certain pattern in the movement between them, which is worth studying" "Let's go and look at the Zhenxing We can't see the Zhenxing clearly, but it seems to be a big ball of gas. Well, let's go again.  Look at Yinghuo Why is Yinghuo red? How is it different from the Zuxing? This is so magical and incredible" In the quiet night sky, dozens of students were together with Yunyang, for the first time  Start using instruments to understand the mysterious starry sky beyond the earth.  Yunyang, who was slightly tired, just smiled faintly and let the students grab the first telescope while he started practicing again on the side, facing the infinite stars in the sky.  It has become Yunyang’s habit to absorb the power of the stars every night.  This habit has been going on for several months now.  The changes this cultivation method has brought to Yunyang are also obvious. Up to now, almost no one dares to show disrespect in front of Yunyang.  This is majesty, the magnanimity brought about by Yunyang's continuous practice.  But obviously, there is one person who doesn't care about Yunyang's majesty.  A few hours after the first telescope was built, a visitor arrived at the secret base unannounced.  With his status, there is really no need to report.  Because he can also be regarded as one of the creators of this secret base.  That is the military leader, Sun Qingzong.  "Let me take a look." Sun Qingzong waved away the students, grabbed the telescope in his hand, observed it briefly, and then put it to his eyes.  I can’t take my eyes away from this look.  Sun Qingzong looked left and right, here and there, and refused to let go for half an hour.  A group of students stood aside, daring to be angry but afraid to speak out.  Finally, Sun Qingzong took away the telescope, and the first words he said to Yunyang left Yunyang stunned.  "This thing is pretty goodwell, it's called a telescopeWhat?  Very good, very good, good, good Our military needs this thing. Yunyang, please make three hundred of them first for use by our military.  ” —————————————————— Khan I wrote until half past midnight, and finally finished the promised third update. Well, it’s time for Rainbow to go to bed.
