Borrow the day to change the day

The long-lost rain in the capital finally fell amidst the thunder and lightning, which made many people happy.

This kind of thunderstorm came and went quickly, and it didn't take long for it to come to an end, and it turned into a drizzle that was ending.

Even so, the weather is no longer stuffy, and the cool breath clears the minds of many people.

But there are also people who have not been affected by climate change, and their minds are still confused. He is Song Yingxing.

Really unable to figure it out, Song Yingxing lay on a recliner, breathed air under the eaves of the Glass Research Institute, and watched the scene outside after the rain to change his mind, which was considered a rest.

This point is also suggested by Zhong Xinghou who just left. If you focus on doing one thing and get nowhere, 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 important things that Zhongxing Hou explained, the mirror and the microscope, had not been tested.

Mirrors are things that make money. It’s not too urgent if they haven’t been tested yet. As long as you keep matching the raw materials and keep testing, you will be able to test them out one day.

But the microscope, according to Hou Zhongxing, is the key to open the door to another world.A brand new world, involving all aspects of the field, but delayed because of my lack of results.

Hou Zhongxing did not lie. This can be verified from the microscopes that have been made so far. When you zoom in on many things, it really breaks the previous understanding.

But this multiple is too low, not enough to meet the demand to open the door.

The reason why the high-power microscope described by Zhong Xinghou has never been produced lies in the lens.

No matter how skilled a craftsman is, he cannot polish a perfect lens;

Based on his own experience, Song Yingxing also discussed and practiced the methods he knew with the craftsmen one by one, but he did not improve much, and the progress has been stagnant.

Thinking back on this journey, Song Yingxing's brain began to ache again.He sat up from the reclining chair, stretched out his hands to hold the water droplets dripping down from the eaves, and his palms were filled in a short while.Then he rubbed it on his face, and under the stimulation of the cold water, his mind became clearer again.

After reclining back in the chair, Song Yingxing recalled Hou Zhongxing who had just come to inspect the Glass Research Institute.

Although Zhong Xinghou didn't scold or urge him, he just discussed some plans with him and gave him examples of other people's success, so that he could see if he could get inspiration.

But Song Yingxing still felt a lot of pressure invisibly. Marquis Zhongxing was his benefactor. If he had no achievements for a long time, someone would definitely talk about it behind his back.

Saying that I am a small matter, after all, I have not done it myself.But if the benefactor is involved, so that Hou Zhongxing is also affected, it would be too sorry for Hou Zhongxing.

Song Yingxing lay there, his eyes could just see the eaves.His eyes were fixed on the raindrops dripping from the eaves, but his mind was still thinking about things, turning a blind eye to the things in front of him.

He thought about his own affairs for a while, the lens for a while, and the example given by Hou Zhongxing, but he couldn't think of a way.

After a long time, the sky cleared, only the remaining rainwater was still dripping from the roof.Song Yingxing couldn't help but sighed again, and beat his head with both hands, trying to drive all these things out of his mind and take a good rest.

He began to recover, and the scene in front of him slowly imprinted in his mind.

Song Yingxing didn't think about anything at this moment, just watched the raindrops dripping from the eaves.

This scene has been seen many times in his life experience.But in order to stop himself from thinking about those things, he focused his attention on his eyes, watching the raindrops drop drop by drop, and the speed slowed down from fast to slow.

After a while, Song Yingxing finally stopped thinking about those things, and his mind no longer ached.

He breathed a sigh of relief, this method of diverting attention is really effective.

Suddenly, Song Yingxing was stunned.The phenomenon in front of him was like another thunderbolt, hitting his mind in bursts.

He saw that the water droplets on the eaves became very slow, because the rainwater on the roof had almost flowed, and it took a long time for the water droplets to form one drop, and then drip down.This process, like the slow motion of a movie, is unfolding before his eyes.

Song Yingxing saw that the water drop gradually grew bigger and bigger, and finally fell down because it was too big.During this process, the water droplet has become a spherical shape.To him, what he saw was a perfect arc.

He himself was thinking about the lens grinding problem he encountered, and now when he saw this situation, he immediately thought of it again.

If this was changed to an ordinary person, it would definitely be impossible to think of it.Even Song Yingxing, if it wasn't because of Zhongxing Hou's inspection and conversation that put him in this state, he would not have cared about the water drops dripping from the eaves, and he would not have discovered the perfection of the water drops.

Immediately, he jumped up excitedly from the recliner, and then ran towards the glass workshop.

According to Song Yingxing's idea, the craftsmen immediately got into action and began to test Song Yingxing's idea that seemed like a fantasy.

He asked the craftsmen in the glass workshop to first burn a thin glass rod, which is the kind of thing that students use to stir beakers in middle school chemistry experiments in later generations.

Then burn the end of the glass rod directly over the flame and let it melt into a glass drop.

The result of the experiment made Song Yingxing very happy. The side of this transparent glass bead is indeed very smooth and perfect.

But the other side of the glass bead is thicker because it is too big, so it is still not very useful.But in any case, it turns out that this approach works.

Although it was already dark at this time, the craftsmen in the whole glass workshop didn't seem to want to rest at all. They all excitedly obeyed Song Yingxing's command and kept doing experiments.

The hard work paid off, and finally the craftsmen under the command of Song Yingxing found a way to get perfect glass beads.

That is to first hold the two ends of the glass rod, roast the middle part of the glass rod on the flame to soften it, and then pull it in half.

At this time, the original middle part becomes slender.Then, put the thin end on the fire at an angle and grill it carefully. At this time, the molten glass juice will flow down the half of the glass rod, and when it reaches the tip, it will condense into a teardrop-like glass bead. .

This perfect convex lens formed entirely by gravity, without any polishing, has a very smooth and perfect surface.

Song Yingxing finally invented the Hooke lens by mistake.Of course, it is definitely not called Hooke lenses now.Because Hooke, who was the first in the world to use this method to make a high-power lens, will come to this world in two years.

According to the same principle, it is also possible to burn a thin stretched but unbroken glass rod, clamp the two ends with a clamp to roast the middle part, and adjust the angle and timing to roast the center to make it semi-liquefied, so as to produce Lenses of various shapes.

Naturally, considerable experience is required to create various convex lenses at will.But this kind of Hooke lens does not need time-consuming polishing, so craftsmen can keep trying in a short period of time, and the speed of experience accumulation is very fast.

Of course, these are all for later.

After a day and a night of experimentation, the world's first high-power microscope was finally born at the Daming Glass Research Institute.
