The long-awaited rain in the capital finally came down amid thunder and lightning, which made many people happy.
This kind of thunderstorm came and went quickly. It didn't take long to come to an end and turned into a drizzle.
Even so, the weather is no longer sultry, and the cool breath clears many people's minds.
But there are also people who are not affected by climate change and are still confused in their minds. He is Song Yingxing.
Really unable to think about it, Song Yingxing lay down on a deck chair under the eaves of the Glass Research Institute to breathe, looking at the scene after the rain outside to change his mind and take a rest.
This is also suggested by Zhongxing Hou who just left. If you are focused on doing something but can't find the solution, you might as well stop and take a rest, and then change your mind, maybe you will find a solution.
Song Yingxing was actually very anxious in his heart, because the two major things explained by Marquis Zhongxing, the mirror and the microscope, had not been tested yet.
Mirrors are a money-making thing. It's not urgent to test them out right now. As long as you keep matching the raw materials and experimenting, you will be able to test them out one day.
But that microscope, according to Zhongxing Hou, is the key to opening the door to another world. A brand new world, involving all aspects of the field, but it was delayed because of his lack of achievements.
Zhongxinghou did not lie. This can be verified from the microscopes that have been made so far. When you magnify many things, you really break the previous understanding.
But this multiple is too low and is not enough to meet the demand to open the door.
The key to the reason why the high-power microscope described by Zhongxing Hou has never been built lies in the lens.
No matter how skilled the craftsman is, he cannot polish a perfect lens;
Based on his own experience, Song Yingxing discussed with the craftsmen one by one the methods he knew and put them into practice, but there was not much improvement and the progress has been stagnant.
Thinking back on this process, Song Yingxing's head began to feel a dull pain again. He sat up from the recliner, stretched out his hands to hold the water drops that kept dripping from under the eaves, and soon the palms of his hands were full. Then he wiped it on his face.
Under the stimulation of cold water, my mind became clearer again.
After lying back on the chair, Song Yingxing recalled Zhongxing Hou who had just come to the Glass Research Institute for inspection.
Although Zhongxing Hou didn't curse or rush him, he just discussed some plans with him and gave him examples of other people's successes to let him see if he could get inspiration.
But Song Yingxing still felt a lot of pressure invisibly. Zhongxing Hou was his benefactor. If he had no achievements for a long time, someone would definitely talk behind his back.
He said that it was a small matter, but after all, he had not done anything. But it would be very sorry for Zhongxinghou if it caused the benefactor to be implicated and Marquis Zhongxing was also affected.
Song Yingxing was lying there, his sight just enough to see the eaves. His eyes were fixed on the rainwater dripping from the eaves, but he was still thinking about things and turned a blind eye to the things in front of him.
He thought about his own affairs for a while, then thought about the lens, and also thought about the examples mentioned by Zhongxing Hou, but he really couldn't think of a way.
After a long time, the sky cleared up, and only the remaining rainwater on the roof was still dripping down. Song Yingxing couldn't help but sigh again, and hit his brain with both hands, trying to drive out all these things from his mind and have a good rest.
He began to come back to his senses, and the scenery in front of him slowly came into his mind.
Song Yingxing stopped thinking about anything at this time and just watched the rainwater dripping from the eaves.
He had seen this scene many times in his life experience. But in order to stop himself from thinking about those things, he focused his attention on his eyes and watched the raindrops falling down drop by drop, with the speed changing from fast to slow.
Slow down slowly.
After a while, Song Yingxing finally stopped thinking about those things, and his head no longer ached.
He breathed a sigh of relief, this method of changing his attention was really effective.
Suddenly, Song Yingxing was stunned. The phenomenon he saw in front of him was like another thunderbolt, hitting his mind one after another.
He saw that the water droplets on the eaves became very slow, because the rainwater on the roof had almost flowed, and it would take a while for the water droplets to form into one droplet and then drip down. This process was like a slow motion movie,
All displayed before his eyes.
Song Yingxing saw the water droplet slowly getting bigger and bigger, and finally it dropped because it was too big. In the process, the water droplet turned into a spherical shape. To him, what he saw was a perfect arc.
.
He himself was thinking about the lens grinding problem he encountered, but now that he saw this situation, he immediately thought of it again.
If it were an ordinary person, he would definitely not be able to think of this. Even Song Yingxing, if it were not for the inspection and conversation by Zhongxing Hou that put him in this state, he would not care about the water drops dripping from the eaves.
Then you won't notice the perfection of this water drop.
He immediately jumped up from the couch in excitement and ran towards the glass workshop.
According to Song Yingxing's idea, the craftsmen immediately started to test Song Yingxing's seemingly fantasy idea.
He asked the craftsmen in the glass workshop to first bake a thin glass rod, which was the kind of thing students used to stir beakers in middle school chemistry experiments in later generations.
Then burn one end of the glass rod directly on the flame and let it melt into a drop of glass water.
The results of the test made Song Yingxing very happy. One side of this transparent glass bead is indeed very smooth and perfect.
However, the other side of the glass bead is thicker because it is too large, so it is still not of much use. But in any case, it proves that this method is feasible.
Although it was getting dark at this time, none of the craftsmen in the glass workshop seemed to want to take a rest. They all followed Song Yingxing's instructions excitedly and kept experimenting.
The hard work paid off, and finally the craftsmen commanded by Song Yingxing found a way to obtain perfect glass beads.
That is to first hold the two ends of the glass rod, bake the middle part of the glass rod over the flame until it becomes soft, and then pull it into two halves.
At this time, the original middle part becomes elongated. Then, hold the thin end diagonally over the fire and grill it carefully. At this time, the melted glass juice will flow down the half of the glass rod.
When it reaches the tip, it will condense into a teardrop-like glass bead.
This perfect convex lens is formed completely by gravity without any polishing, and its surface is very smooth and perfect.
Song Yingxing finally invented the Hooke lens by accident. Of course, it is definitely not called Hooke lens now. Because Hooke was the first in the world to use this method to make high-power lenses, and there were two other people.
He will not come into this world until years later.
According to the same principle, you can also use a glass rod that is stretched but not burned, and the two ends are clamped with clamps to grill the middle part. Through clever angle and timing adjustments, the center of the rod is grilled to semi-liquefy it to make it.
Lenses of various shapes.
Naturally, it takes considerable experience to create various convex lenses as you wish. But this kind of Hooke lens does not require time-consuming polishing, so craftsmen can keep trying in a short period of time, and experience is accumulated very quickly.
Of course, these are all things for later.
After a day and night of experiments, the world's first high-power microscope was finally born at the Daming Glass Research Institute.
