According to Su Hao's guess, without mechanical assistance, it would take several days for the Hao family and his son to grind out the lenses of a pair of telescopes. Who would have thought that the whole family would not get up the next morning.
At that moment, Su Hao heard Youru banging the door knocker of his house desperately, shouting excitedly as he slapped it back: "My good nephew, my good nephew, have you ever gotten up?"
Damn it, is there anyone who can disturb a clear dream like this?
Although Su Hao complained in his heart, he put on his clothes quickly and ran downstairs to open the door.
Standing outside the door were Hao Yizong and Hao Qing, father and son. Hao Yizong held an object composed of two cylinders in his hand. In the entire Ming Dynasty, only Su Hao could recognize it. This was clearly
A telescope.
"What, Uncle Hao, have you made a telescope?" Su Hao asked.
"It's done, it's done. Take a look, my dear nephew, but is this thing good?" Hao Yizong handed the telescope to Su Hao's hand, with an irrepressible smile on his face and his hands trembling a little.
.
Su Hao took the telescope, looked at it carefully, and couldn't help but feel shocked. The two lens barrels of the telescope were rolled out of iron sheets, and were covered with cloth. They felt very comfortable in the hand. The lenses were made of
After wrapping the edges of the cowhide cut into thin strips and then inserting it into the lens barrel, the seams are very tight and there is no light leakage. The two objective lenses and the two eyepieces are polished very smooth and neatly. Looking with the naked eye, you can see that
Not a single flaw.
Su Hao tried to raise the telescope, put the eyepiece in front of his eyes, and looked into the distance along the alley at the door. The breakfast stall at the entrance of the alley was suddenly pulled to Su Hao's eyes, and he could even see the vendor clearly
That pimple on the face.
"What is this? Let my brother see it?"
Deng Kui's voice came from behind Su Hao. Deng Kui and Hao Tong maintained their habit of being in the army. They got up very early every morning and practiced martial arts in the back garden. When they heard Hao Yizong calling the door, they entered
Then he came to the front door and met Su Hao checking out the newly released telescope.
Su Hao smiled and handed the telescope to Deng Kui's hand. Deng Kui took it and imitated Su Hao's example, holding the telescope flat in front of his eyes and bringing his eyes to the eyepiece. Since he couldn't choose the target, he couldn't distinguish it for a while.
What did he see? Su Hao pushed the telescope with his hand and pointed it at the target in the distance. Deng Kui was stunned for a moment and suddenly shouted: "Lao Yao, what a magical weapon this is!"
Hao Tong, who was standing next to him, heard Deng Kui's exclamation, and quickly took the telescope from Deng Kui's hand, and looked at it in front of his own eyes. The result was the same as Deng Kui, and he was also excited and screamed. The two of them screamed with excitement.
The soldiers took turns trying out the telescope, looking south and then north, and then raising the lens to look at the tall trees in the distance. They had a great time.
"My nephew, what are you going to do, is this?" Hao Yizong asked. The performance of Deng Kui and Hao Tong did not surprise him at all, because he was also so shocked when he just made the telescope.
Su Hao nodded and said, "That's it. I thought it would take several days to polish these lenses, but I didn't expect Uncle Hao to polish them so quickly."
Hao Yizong said: "Since my nephew left yesterday morning, my father and my son have been grinding these lenses non-stop. At first, we didn't get the point and even wore out a few lenses. By dinner time, we had polished these four lenses.
film, and then making these two lens barrels, which also took a lot of work.”
Su Hao said: "Uncle Hao and Brother Hao's craftsmanship is really amazing. Not only are the lenses of these binoculars well-ground, but the barrels are also exquisite. My nephew really admires them."
Hao Qing put his hands behind his back and said to Su Hao: "Brother Xian, although this telescope is good, Brother Yu feels that there are still some shortcomings. This telescope can only see a fixed place. If you want to look elsewhere, it will be a bit blurry."
Already."
Su Hao smiled and said: "This is not a big problem, but I didn't make it clear yesterday. The distance between the front and rear lenses should not be fixed, so that it can be adjusted according to the distance of the place you want to see.
The position of the lens, this process is called focusing."
Hao Qing smiled slightly and stretched out his hand behind his back. Only then did Su Hao see that his hand was holding a slender cylinder three or four feet long. The cylinder was divided into two parts and put together.
The interface seems to be movable.
"Monocular telescope!" Su Hao exclaimed in surprise. He took the cylinder and took a look. Sure enough, a lens was installed at both ends of the cylinder. They were also installed according to the requirements of the objective lens and eyepiece. He put the monocular
He put the telescope in front of him and pointed the lens into the distance. At first, the scenery in the lens was a little blurry, but he pulled the lens barrels together back and forth, and things in the distance became clear and distinguishable.
It seems that the craftsmen of ancient China should not be underestimated. They actually thought of the problem of adjusting the focal length without any teacher, and solved it with the simplest method.
Su Hao turned the monocular telescope and took a look. He found that the objective lens in front was one size larger than the binoculars, and the magnification was also higher. In this way, the telescope could see farther, and
The range that can be seen simultaneously is also wider.
"Hey, the lens in front of this telescope is not the glass lens we made at the beginning, right?" Su Hao asked.
Hao Qing said with some embarrassment: "Last night, after making the binoculars, my father and I were thinking about the principles of this telescope. Later, we thought that if we could make the lenses larger, we might be able to see further.
Far away. So, we took a few worn-out glass pieces and re-melted them in the furnace, cast a larger glass piece, and ground it into the lens of this telescope."
"Then you haven't slept all night?" Su Hao asked. Only then did he notice that the eyes of the Hao family and his son were full of bloodshot eyes. They stayed up all night to do Qian's work, and it was Qian's meticulous work of sharpening the lens. It should be very...
Tiring.
"Younger is young, and it's okay to stay overnight. Old man is old and can't stand it until the fourth watch, so he went to take a nap for a while." Hao Yizong replied.
Su Hao said apologetically: "Oh, blame me. Actually, this matter is not so urgent. Why do you have the nerve to let Uncle Hao and Brother Hao stay up late to catch up on the work?"
Hao Yizhong said: "What does this mean? When I was working in the miscellaneous work bureau, I stayed up for seven days and seven nights. This telescope made by my nephew Ming is really a clever work. I made such a thing.
It’s always hard to sleep well before eating and drinking. What makes me happy is that the old man and his son stayed up all night, and their hard work was not in vain. Being able to create such a magical thing means that this life is not in vain.”
"This is all thanks to Brother Gai's wonderful idea, otherwise we wouldn't have been able to do this." Hao Qing added.
Su Hao waved his hand and said: "I just had an idea and thought that I could do this. It is thanks to craftsmen like my uncle and eldest brother that I can actually turn this idea into reality. If I were to do it by myself, I might not be able to polish a single lens in my lifetime.
Woolen cloth."
When everyone entered the conversation room, Yang Gendi and Lu Xiuer also finished washing and walked out. Yang Gendi greeted politely: "Everyone, please stop staying outside and come in and sit. I will make breakfast for you right away."
Hao Yizong and Hao Qing hurriedly saluted Yang Gendi. Su Hao introduced them to each other, and everyone spent some time on the issue of address. Finally, it was decided that Yang Gendi would call Hao Yizong his eldest brother, and Hao Yizong would call Yang Gendi his sister-in-law. After we met, they would become
As relatives, we should move around each other frequently.
Hao Yizong and Hao Qing had breakfast at the Su family. Su Hao discussed the improvement of the telescope with them again and suggested that they install a gear device on the telescope barrel so that the wheel can be used to adjust the focus. The Hao family
The father and son completely understood the design as soon as they heard it, so they finished their meal hastily and went back to make other telescopes anxiously.
After seeing off the Hao family and his son, Su Hao looked at Deng Kui and Hao Tong who were playing with the telescope with a smile, and asked: "You two, how do you think this thing is? Can you give me an evaluation?"
"This thing is really useful. It can give the scouts in our army a pair of clairvoyance. In front of the two armies, if the commander uses this thing to observe the enemy, he will definitely be able to strategize and win a thousand-mile victory." Hao Tong did not hesitate to use the best comments to evaluate.
This telescope in my hand.
"Well, as long as you think this thing is useful, should we talk about the price now?" Su Hao asked, still smiling.
Deng Kui stared and said, "Master Su, how much do you plan to ask our brothers for such a thing?"
Su Hao said: "This is not how much money I want from your brothers, but how much money I want from Deputy General Deng. This is military equipment, and it should be purchased with military expenses, right?"
"Well, that's what I mean." Deng Kui said, "Please tell me the price."
Su Hao stretched out a hand, spread his fingers, flipped it back and forth, and said: "1oo two pieces, how about one?"
"You are robbing money!" Deng Kui said loudly, "Our brothers saw with our own eyes how you made this thing yesterday, but it's just a few stones boiled. How much is it worth? Polishing mirrors and other things are all worth it.
It was Uncle Hao and my eldest brother who did it. They all said they didn’t need any money, but you actually asked for 100 taels?"
Su Hao snatched the telescope from Hao Tong's hand, hid it behind him, and said, "Do you want it? This telescope is only 100 taels a piece. Unless you come to snatch it, you have to pay for it first."
"You..." Deng Kui and Hao Tong were both dumbfounded. If they really wanted to use force, they certainly weren't afraid of Su Hao. They didn't even have to be afraid of Su Hao reporting to the government, because their backers were much stronger than the Fengcheng County government.
But the problem is, everyone is so familiar with each other, how can there be any reason to turn against each other and grab things? Besides, Su Hao dared to challenge them like this because Tu Wenhuan admired him very much. Deng Kui and Hao Tong were both nominally sent by Tu Wenhuan to protect him.
Yes, how can there be any reason to fight against the person being protected?
