Release that Witch Chapter 205: Microscope
After repulsing Timothy's troops, small town returned to calmness.
Roland selected three people from City Hall Ministry of Education, and then added two teachers to form a team, and took the books copied by Soraya to Longsong Stronghold. No matter how much effect he can achieve, he finally took the first step on the assimilation stronghold.
Although Petrov is not good at commanding battles, it does perform well in administration. In just one week, two thousand applicants for road construction handyman came to small town one after another under the **** of Knight. If it were not for the second batch of ten sets of furnace to be put into production, Roland would not dare to make up his mind to establish a hard road between the two places. Now, he finally has a chance to squander.
This road is named Kingdom Highway by Roland, and is fully responsible by Minister of Construction Karl. Its structure is exactly the same as small town street. It is a cement-stabilized gravel layer. In the era when there is no heavy truck, such a road is sufficient to undertake transportation tasks. And the drainage performance is good, you can also see situation additional asphalt or concrete.
In terms of construction materials, four steam engine-driven mills have replaced manpower to perform stone crushing work, and can produce dozens of tons of crushed stone every day. The weak transportation capacity has limited the further increase in production. It takes more than a hundred people to carry a horse cart for one day before it can be delivered to the construction site. If it is the next-generation road tyre dump truck, it can be transported in one car.
In addition to the four clay bricks in the furnace area, the remaining blast furnaces have been put into the production of cement powder. After many component tests and iron powder supplied by the mine, the cement produced by small town is now of high quality and stability. Are far more than the original batch.
But the transport of crushed stone and cement powder by the brigade has also brought a lot of negative impacts to small town, the most serious of which is the problem of dust. In the afternoon, with only a slight wind blowing, you can see the dense dust flying across the sky, and the streets have turned pale yellow. Although most townspeople don't mind such a situation, for Roland, there is nothing worse than closing the windows and doors in the hot summer.
So the carriage carrying cement and crushed stone was quickly fitted with a cover plate to reduce scattering during transportation. At the same time, with the promotion of Leaf's ability, small town was covered by tree shades in just a few days, and the leafy sycamore trees lined up symmetrically along the street, and looked green in the eyes. Coupled with H.M.S. Roland calling on all citizen to actively sprinkle water to reduce dust, this problem was quickly improved.
The straight line distance between the two places is less than 70 kilometers, but considering that the foot of the mountain extended by Impassable Mountains should be avoided during road construction, the total length of this road is about 100 kilometers, and the construction period is expected to be one year. With good quality roads, some vehicles can also come in handy, such as bicycles and steam cars.
In his conception, the development of education and the construction of roads are measures to connect the two places together, just like the urban integration vigorously promoted in later generations. After the land development between the two places is completed, Longsong Stronghold and Border Town will merge into a huge city. If he can turn the hill at the southern end into a part of the city, and then open up the marginal mountains, he will even have the seaport.
Of course, it takes more people to develop so much land, and in order to cope with possible future wars, the city must be self-sufficient in agriculture while also providing a large number of workers for industrial production. According to preliminary calculations, he needs to introduce about 100,000 people, while Kingdom Capital, the largest city in Greycastle, is only about 20,000 or 30,000 people.
Roland has its sights on Greycastle north and southern region. Both places have experienced the flames of war. When the cold winter comes, it is likely that a large number of refugees will be short of food and clothing. Just provide hunger-filled food and a warm shelter to absorb them into Border Town. Even the refugees of Eternal Winter and Wolf Heart are under his consideration. To this end, he also wrote a letter to the businessman Margery, asking her to help inquire about situation in these two countries.
...
After writing the recent development plan, the prince folded the paper into a drawer, stretched his waist, and decided to go to the Anna room to see how her lenses were cut.
Since understanding the reasons for the evolution of Soraya, he intends to make a microscope that can observe the structure of cells.
If you can observe the wonderful micro-world with your own eyes, maybe it will trigger more witch to evolve new abilities, and it will arouse their interest in learning.
For making microscopes, it is not difficult to use two convex lenses for magnifying the target. The difficulty lies in the fact that the focal length of each lens is different, so matching the eyepiece and objective lens is a delicate task. The distance of each lens.
After he briefly explained the principle of convex lens imaging, he handed it to Anna a few good-quality crystals, and let her try to cut the lenses and measure their focal length. Three days have passed, and to what extent Anna has achieved it, Roland is full of curiosity.
Going to the door of Anna room, Nightingale smiled at him, standing against the wall, it seemed to indicate that she would not follow up. Since she reduced the stealth time, Roland no longer has to guess the other party's whereabouts, and Anna When alone, the Nightingale will always choose to stand far away.
Pushing the door open, Anna is sitting at the table and playing with a metal pipe.
"How is it?" he stepped forward and asked.
As soon as I asked the question, Roland froze. I saw a few instruments that looked like microscopes on the table, and they were very close to the schematic diagram I drew.
"I made a few prototypes according to the drawings you gave me, and indeed I can see many details that are usually difficult to find," she raised her head, and the slender bangs slid down to the side. "I used it to observe the paper Faces, leaves, and standing water, and found that they look very different from normal days. "Since the hot air balloon trip, Anna no longer uses honorifics when they are alone, which makes him feel very relaxed.
"How did you make it," Roland was surprised, "that diagram is just a rough outline."
"The outline is enough," Anna laughed. "You see, as long as you fix the eyepiece and objective lens at a proper distance, you can magnify it, and then fix them with an iron tube, and the main body of the microscope will be Finished. When I tested the magnification effect of the lens, I found that the objective lens and the observation target must be kept within a certain distance to see a clear image, and the hand would be blurred, as you can see from the diagram. You need a The lens holder is fixed on the shelf, and the table underneath the target can be moved up and down to get the best object distance. "She paused," The bottom piece of the diagram is more difficult to understand, you can tell what it is for Right? "
Roland glanced at the drawings and found that I made a mistake. It was a reflector to increase the light passing through the target. In this era, mercury mirrors have not been invented. Generally, noble is still finished with copper or iron mirrors. In appearance, in the palace, a silver sheet is pasted behind the glass to obtain a better reflection effect. Even without this mirror, the microscope can be used as long as there is sufficient sunlight.
After he explained it in detail, he could n’t help but sigh with astounding comprehension of Anna. Based on the rough outline drawing, he made a nearly complete product, and it was impossible for him to do it by himself.
Looking at the white neck that was exposed when the other person looked down to detect the new lens barrel, Roland couldn't help but stepped forward and wanted to kiss, but she pressed her face with her hand and gently pushed it away. , Your Highness, I am busy. "
"唔 ... Okay." (To be continued. If you like this work, you are welcome to start casting, and your support is my biggest motivation. Mobile phone users please read.)
