Chapter 843 839【Microscope】

  When Li Zicheng planned to visit the Nanjing Night Market, Zhao Han came to the queen's bedroom.

  The maid took off her coat, Fei Rulan hung up the clothes herself, walked back and said, "Husband, the crown prince is short-sighted."

   "Huh?" Zhao Han thought he heard it wrong.

  Fei Rulan said: "Mr. Zhang from Zhan Shifu said that the prince likes to read books close by. Mr. Zhang felt bad, so he put the book far away for the prince to read. The prince said that the handwriting was very blurry."

  Zhao Han couldn't laugh or cry. When he thought of his son wearing glasses, he thought it was funny and unreal.

  Although, many civil servants also wear a pair of glasses on their chests when they are in court.

  Fei Rulan also said: "Mr. Zhang suggests wearing glasses, but I'm afraid it will damage the prestige of the prince."

   "It won't hurt any prestige, you should get glasses if you need them, and choose the best optician." Zhao Han said.

  Fei Rulan said: "Master Sun of Qintian Academy is a first-class mirror master in the world."

   "Then ask Master Sun to make glasses for the prince." Zhao Han didn't know what Master Sun was doing.

  Dr. Sun's name is Sun Yunqiu, from Wujiang County, Jiangsu Province, and he is only 25 years old this year.

  Being a master of Qintian Academy at a young age is definitely not due to his glasses grinding technology. This old man graduated from Yangzhou University, did not take the imperial examination, and was directly admitted to Qintianyuan.

   Moreover, before being admitted to Qintian Academy, Sun Yunqiu had already invented the microscope!

   This is not the butterfly effect brought about by Zhao Han. In real history, Sun Yunqiu also invented the microscope.

  China had glasses in the Yuan Dynasty, but until the end of the Ming Dynasty, glasses were precious items. The main reason is that it is not easy to grind, and after grinding, it often does not match the degree. At the end of the Ming Dynasty, Western learning spread eastward, and simple knowledge of optics gradually spread to China, and finally a breakthrough was made in eyeglass manufacturing technology, which is why Qian Qianyi said that eyeglasses are a Western product.

   And Sun Yunqiu, with his own power, directly made the glasses that the dignitaries could afford, directly at the price of cabbage—each pair of glasses only cost two or three cents of silver (one tael equals 100 cents).

  This gentleman studied at Chen Tianqu, a disciple of Matteo Ricci, and mastered some knowledge of mathematics and physics. He also invented the tuo car for grinding lenses, and pointed out the difference between presbyopia, hyperopia and myopia, and equipped glasses according to the actual conditions of patients. He even wrote the book "History of Mirrors", which disclosed all the methods of making glasses, which eventually caused the cost of making glasses to plummet.

  It's a pity that when the Qing army went south, Sun Yunqiu's livelihood was difficult and he had to make a living by collecting herbs. He died of illness at the age of only 34.

  By the way, Sun Yunqiu can also make chime clocks.

  Sun Yunqiu in this time and space will definitely not go to collect medicine anymore, and he doesn't even focus on grinding lenses.

  He invented the microscope and kept improving it. Now he does research every day and observes various microorganisms with a microscope. The Qintian Academy even plans to set up a separate "microscopic hall" to allow researchers to explore the microscopic world.

   "Wenyu, His Majesty summoned you!" Fang Yizhi called in person.

  Sun Yunqiu, who just invented the microscope slide, was watching the cute tardigrades swimming, and raised his head at a loss when he heard the words: "What did His Majesty call me for?"

  Fang Yizhi said: "I don't know, you just entered the palace."

"Wait a minute," Sun Yunqiu said, "The lenses I polished a few days ago can see microbes more clearly, and today I discovered a new kind of water worm. After I finish my observation and record, I will go to the palace to see Your Majesty. "

  Fang Yizhi was speechless about this, and actually stopped urging, and turned around to ask the female officer to wait a moment.

  Sun Yunqiu continued to fiddle with the microscope, and then took a pen to start the portrait, drawing the whole picture of the tardigrade from different angles, and also commented on the side: water bug 21 (tentative name), green body, hexapod...

  The female officer was already anxiously waiting, and Sun Yunqiu finally got up, went out and clasped his fists and said, "Thank you for waiting."

  As soon as this guy left, the researcher next to him rushed to occupy the microscope. The lens of this microscope is a newly polished ultra-high magnification, the only one in the entire Qintianyuan, and everyone is waiting in line to see it.

  Bringed into the palace in a daze, Sun Yunqiu didn't pay attention to the scenery along the way at all, and his mind was still on the things under the microscope just now.

   "Your Majesty, Your Majesty, Prince, brought by Master Sun."

  Sun Yunqiu finally came back to his senses, and hurried forward to meet him.

   Zhao Han did not talk about myopia, but asked: "I heard that you invented the microscope, how did you make it?"

Sun Yunqiu replied: "Reporting to Your Majesty, although my ancestral home is Wujiang County, my uncle has lived in Hangzhou with my uncle since he was a child because he was doing business in Hangzhou. Eighty percent of the glasses in the world are made by Hangzhou mirror craftsmen. I am very curious about glasses, so I stand all day long. Watch them grind from the sidelines."

"Later, I went to school and learned geometry and physics, the true meaning of Fang Xiaoguang's optics. When I was in middle school, I began to grind lenses by myself. I always felt that it was not easy to polish lenses, so I thought about inventing a tuo cart. In fact, it is not The principle of the invention comes from water oranges, which have existed since ancient times.”

"When I was studying in university, I first learned how to make binoculars, and later made things such as kaleidoscopes and night mirrors. I thought that a binoculars can see very far objects, so why can't I make a set of lenses to see things that are very near and very small?" things? Hence the microscope.”

   "Great kindness!" Zhao Han praised.

  Sun Yunqiu said: "Your Majesty is admirable, the microscope is not very useful, it can only observe some small bugs, and satisfy the curiosity of the members of the Qintian Academy."

   "Otherwise," Zhao Han shook his head and said, "Why don't you observe the patient's sputum? For example, for a certain cough, compare the sputum of the same disease under a microscope. Perhaps this disease is also caused by small bugs."

   "Bugs cause cough?" Sun Yunqiu couldn't keep up with the emperor's rhythm.

Zhao Han continued: "When you come into contact with patients and sputum, you must wear a mask, which is a cotton mask to prevent the plague. When observing, you should wash the contact with boiling water, and your hands should be washed repeatedly. Yes Yes, it's better to wear gloves, and put the gloves in boiling water afterwards."

  The emperor has a mission, of course Sun Yunqiu dare not refuse: "I obey the order."

  Fei Rulan reminded from the side: "Your Majesty, let's talk about the prince first."

   Zhao Han pointed to Zhao Kuanghuan: "My son is nearsighted, please trouble Sun Qing to get a pair of glasses."

  Sun Yunqiu said: "Your Majesty, I want to go home to fetch the optometry."

   "Go." Zhao Han nodded.

  Sun Yunqiu took the royal carriage, go and come back quickly, and get a set of optometry equipment.

  He first opened the prince's eyelids and observed the condition of the eyes with a magnifying glass. Then the cardboard was erected, and the character "Jia" in different directions and sizes was written on the cardboard, asking the prince to point out the specific direction with one eye blindfolded.

  Fei Rulan couldn't understand, and after Sun Yunqiu finished his work, he asked curiously, "What are you doing?"

Sun Yunqiu replied: "Returning to my mother, I think the eyes are convex lenses. For some reason, the focus moves forward, so I can't see clearly. Using concave lenses to make glasses can adjust the focus. And because everyone's myopia focus is different, in When wearing glasses, it is necessary to measure how much the focal point has changed. The characters 'A' on the cardboard are of different sizes. Each size represents a focal position, so it can be matched with different concave lenses."

   "I see, Master Laosun is here." Fei Rulan smiled, but the more she listened, the more confused she became.

  Zhao Han suddenly said: "You guessed that the eyes are a convex lens, why don't you prove this conjecture?"

  Sun Yunqiu was stunned for a moment: "Chen... how can I prove it?"

  Zhao Han said: "You can go to the butcher's place and dig out the eyes of freshly killed pigs for observation. Or, simply go to the medical school, where human corpses are often dissected."

   Today's medicine is divided into several factions, the most unacceptable is the "Ziyang School".

  It originated from Ziyang Medical College in Gezao Mountain, Jiangxi. When Zhao Han's territory was only in Jiangxi, he kept throwing the enemy's corpses for autopsy.

  Nowadays, detailed human skeleton diagrams, muscle diagrams, blood vessel diagrams, etc. have all been drawn by the doctors of the Ziyang School. However, the dissection process was too disgusting and violated traditional customs, so that the Ziyang School was cast aside by traditional doctors, and there were even rumors that Gezaoshan doctor liked to eat people.

   Gezao Mountain, the ancestral home of the Taoist Lingbao sect, the incense of the Taoist temple is getting weaker and weaker, and the common people are too scared to go up the mountain.

   But, it's all spurned, but the medical research results of the Ziyang School are quietly studied by traditional doctors. No matter which school of famous doctors they are in, they will secretly collect those human anatomy diagrams, and only allow the disciples who entered the room to study them in private.

   After a few days.

   After fine polishing by Sun Yunqiu, a pair of glasses was sent to the prince.

  Zhao Kuanghuan put on his glasses and looked at the clear scenery around him, like a blind man who had regained his light, and smiled from ear to ear in an instant.

  Zhao Han couldn't help laughing, thinking of his son as an emperor.

   An emperor wearing glasses, sitting on the golden throne, that scene really made people laugh.

   It may be similar to Emperor Yongzheng, who had 35 pairs of glasses in different styles and materials. After washing up every morning, the first thing Yongzheng did was to think about which pair of glasses he should wear today.

   "Scary Step by Step" and "The Legend of Zhen Huan" were not filmed enough to restore history, and they didn't give Si Ye a complete pair of glasses.

   "Mom, I can see clearly!" Zhao Kuanghuan shouted happily.

  Fei Rulan looked at her son from the side, and suddenly said: "The glasses frames should be replaced with better-looking ones. The tortoiseshell tribute from Nanyang Fanbang can be polished into glasses frames by artisans."

  The mother and son were having fun, while Zhao Han was playing with the microscope.

  Whatever the emperor wants, Qintianyuan will send it naturally, and they will make a new one by themselves.

  Sun Yunqiu guided with his hands and said: "Your Majesty, this is a slide (glass slide). The object you want to observe must be placed on the slide first..."

  Through the two lives before and after, Zhao Han played with a microscope for the first time, and he was inevitably a little excited.

  He saw the tardigrade very quickly, and excitedly shouted: "Queen, come and see!"

  Fei Rulan lay beside Zhao Han, took a closer look at her glasses, and immediately backed away in fright, exclaiming, "What an ugly monster!"

   Zhao Kuanghuan yelled, "I want to see it too!"

  Father and son obviously have the same style, and Zhao Kuanghuan also found the tardigrade interesting, lying there for a long time without moving his eyes.

The invention of the microscope made Zhao Han feel very happy: "Autumn is crisp, it's the perfect weather for hunting. Li Zicheng hasn't left Beijing yet, right? Invite him to go hunting. Also, Sun Qing will go too. You have made great contributions to inventing the microscope and accompany me to hunt." Easy easy."
