When Li Zicheng planned to visit the Nanjing night market, Zhao Han came to the queen's palace.
The maid took off her coat, and Fei Rulan hung up the clothes herself. She came back and said, "Husband, the prince is short-sighted."
"Ah?" Zhao Han thought he heard wrongly.
Fei Rulan said: "Mr. Zhang from Zhan Shifu said that when the prince reads a book, he likes to hold it close to read. Mr. Zhang felt bad and put the book far away for the prince to read. The prince said the handwriting was very blurry."
Zhao Han couldn't laugh or cry. When he thought about his son wearing glasses, he felt it was funny and unreal.
Although many civil servants also wear glasses hanging on their chests when attending court meetings.
Fei Rulan added: "Mr. Zhang suggested wearing glasses, but he was afraid of damaging the prince's dignity."
"It won't damage your dignity. Just wear glasses if you need them. Choose the best optician." Zhao Han said.
Fei Rulan said: "Master Sun from Qintian Academy is one of the best mirror masters in the world."
"Then let Master Sun provide the prince with glasses." Zhao Han didn't know what Master Sun did.
Dr. Sun's name is Sun Yunqiu, a native of Wujiang County, Jiangsu Province, and he is only 25 years old this year.
He is a master of Qintianyuan at a young age, which is definitely not due to his skills in sharpening glasses. This man graduated from Yangzhou University and did not take the imperial examination and was admitted to Qintianyuan directly.
Moreover, Sun Yunqiu had already invented the microscope before he was admitted to Qintian Academy!
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 considered expensive items. The main reason was that they were not easy to grind, and after grinding them out, they often did not match the prescription. At the end of the Ming Dynasty, Western learning spread eastward, and simple knowledge of optics
, also gradually spread to China, and the glasses production technology finally made a breakthrough, so Qian Qianyi said that glasses are a Thai and Western thing.
And Sun Yunqiu single-handedly made glasses that were affordable for dignitaries directly available at cabbage prices - each pair of glasses only cost two or three cents of silver (1 tael equals 100 cents).
This gentleman studied under Matteo Ricci's disciple Chen Tianqu, and mastered some knowledge of mathematics and physics. He also invented a tractor for grinding lenses. He also pointed out the differences between presbyopia, farsightedness, and myopia, and prescribed glasses according to the patient's actual condition.
He even wrote a book called "Mirror History" to disclose all the methods of making glasses, which ultimately caused the cost of making glasses to plummet.
Unfortunately, when the Qing army went south, Sun Yunqiu's life 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 self-ringing bells.
Sun Yunqiu in this time and space will definitely not go to collect medicine anymore, or even just focus on grinding lenses.
He invented the microscope and continued to improve it. Now he conducts research every day and uses microscopes to observe various microorganisms. Qintianyuan even plans to set up a separate "microscope museum" to allow researchers to explore the microscopic world.
"Wenyu, Your Majesty has summoned you!" Fang Yizhi called in person.
Sun Yunqiu, who had just invented the microscope slide, was observing the swimming of cute tardigrades. Hearing this, he looked up blankly and asked, "What is your Majesty calling me for?"
Fang Yizhi said: "I don't know, just go into the palace."
"Wait a minute," Sun Yunqiu said. "The lenses I polished a few days ago can see microscopic insects more clearly. Today I discovered a new kind of water bug. After I finish observing and recording, I will go to the palace to see His Majesty.
"
Fang Yizhi was speechless about this. He actually stopped urging and turned around to ask the female officer to wait a moment.
Sun Yunqiu continued to fiddle with the microscope, then took a pen and started drawing, drawing the whole picture of the tardigrade from different angles, and also annotated on the side: water bug 21 (tentative name), green body, six legs...
The female officer was already waiting impatiently. Sun Yunqiu finally got up, went out, clasped his fists and said, "I'm sorry to have to wait."
As soon as this guy left, the researchers next to him hurriedly ran to occupy the microscope. The lens of this microscope was the latest polished ultra-high power. It was the only one in the entire Qintian Academy. They were all queuing up to see the strange thing.
Being brought into the palace in a daze, Sun Yunqiu didn't pay attention to the scenery along the way. His mind was still on what he had just seen under the microscope.
"Your Majesty, Your Majesty, Your Majesty, and Master Sun are here to bring you."
Sun Yunqiu finally came to his senses and hurriedly came forward to pay his respects.
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 I am originally from Wujiang County, my uncle was doing business in Hangzhou, so I lived in Hangzhou with my uncle since I was a child. Eighty percent of the world's glasses are made by Hangzhou mirror craftsmen. I was very curious about the glasses, so I stood there all day long.
Watch them polish it."
"Later I went to school and learned geometry and physics, and I learned the true meaning of optics. When I was in middle school, I started to grind lenses by myself. I always felt that grinding lenses was not easy, so I thought about inventing a tug-of-war. In fact, it didn't count.
The invention, the principle comes from the water orange, which has been around since ancient times.”
"When I was studying in college, I first learned to make a telescope, and later made a kaleidoscope, a night mirror and other objects. I thought that a telescope can see extremely far things, so why can't I grind a set of lenses to see extremely close objects?
The thing? Hence the microscope."
"Great kindness!" Zhao Han praised.
Sun Yunqiu said: "Your Majesty is ridiculous. The microscope is of little use. It can only observe some small insects to satisfy the curiosity of the scholars of 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 disease, compare the sputum of the same disease under a microscope. Perhaps this disease is also caused by small bugs."
"Little bugs cause coughing?" Sun Yunqiu couldn't keep up with the emperor's rhythm.
Zhao Han continued: "When you are in contact with patients and sputum, you must wear a mask, the kind of cotton mask that is used to prevent the plague. During observation, you must wash the contact objects with boiling water, and your hands must be washed repeatedly. Yes.
It’s best to wear gloves and soak them in boiling water afterwards.”
The emperor had a mission, and of course Sun Yunqiu did not dare to refuse: "I obey the decree."
Fei Rulan reminded from the side: "Your Majesty, let's talk about the prince first."
Zhao Han pointed at Zhao Kuanghuan: "My son is nearsighted, please ask Sun Qing to get a pair of glasses."
Sun Yunqiu said: "Your Majesty, I want to go home and get some things for my optometry."
"Go." Zhao Han nodded.
Sun Yunqiu took a royal carriage and went back quickly to get a set of optometry equipment.
He first opened the prince's eyelids and used a magnifying glass to observe the condition of his eyes. Then he put up a cardboard with the word "A" written in different directions and sizes, and asked the prince to point out the specific direction with one eye covered.
Fei Rulan couldn't understand. After Sun Yunqiu finished his work, he asked curiously: "What are you doing?"
Sun Yunqiu replied: "Reporting to the empress, I think the eye is just a convex lens. For some reason, the focus moves forward, so you can't see clearly. Making glasses with concave lenses can adjust the focus. And because everyone's myopia focus is different, in
When wearing glasses, you must first measure how much the focus has changed. The letters 'A' on this cardboard are of different sizes. Each size represents a focus position, so it can be matched with different concave lenses."
"I see, Master Laosun is here for you." Fei Rulan smiled, but the more she listened, the more confused she became.
Zhao Han suddenly said: "You guessed that the eye is a convex lens, why don't you confirm this guess?"
Sun Yunqiu was stunned: "Chen... how should I confirm this?"
Zhao Han said: "You can go to the butcher and dig out the eyes of the freshly killed pigs for observation. Or you can simply go to the medical school, where human corpses are often dissected."
Today's medicine is divided into several sects, and the most unacceptable one is the "Purple Yang School".
It originated from Ziyang Medical College in Gezaoshan, Jiangxi. When Zhao Han's territory was only in Jiangxi, he kept throwing the enemy's corpses for autopsy.
Today, detailed human skeleton diagrams, muscle diagrams, blood vessel diagrams, etc. have all been drawn by doctors of the Ziyang School. However, the anatomy process is so disgusting and goes against traditional customs that the Ziyang School is spurned by traditional doctors, and even
There are rumors that Dr. Ge Zaoshan likes to eat people.
In Gezao Mountain, the ancestral home of the Taoist Lingbao sect, the incense of the Taoist temple is getting weaker and weaker, and the people are too scared to go up the mountain.
However, despite being despised, the medical research results of the Ziyang Sect were secretly studied by traditional healers. No matter which sect they were, famous doctors would secretly collect those human anatomy diagrams and only let their disciples study them privately.
A few days later.
After being carefully polished by Sun Yunqiu, a pair of glasses was delivered to the prince.
Zhao Kuanghuan put on his glasses and looked at the clear scenery around him, as if a blind man had regained his sight. He instantly smiled from ear to ear.
Zhao Han couldn't help but laugh, thinking of his son becoming the emperor.
An emperor wearing glasses, sitting on the golden throne, the scene is really a bit dramatic.
Perhaps it would be similar to Emperor Yongzheng. Yongzheng had 35 pairs of glasses, with 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.
Both "Jingxin" and "The Legend of Zhen Huan" were not filmed enough to restore history, and the fourth master was not even given a pair of glasses to wear.
"Mom, I can see so clearly!" Zhao Kuanghuan shouted happily.
Fei Rulan looked at her son from the side and suddenly said: "The spectacle frames should be changed to better-looking ones. The tortoise shells sent as tribute from Southeast Asian countries can be polished by craftsmen into spectacle frames."
The mother and son were having fun there, while Zhao Han was playing with the microscope.
Whatever the emperor wanted, Qintianyuan would naturally bring it to him, and they would just make it from scratch.
Sun Yunqiu guided him hand in hand: "Your Majesty, this is a slide (glass slide). The objects you want to observe must be placed on the slide first..."
Two lifetimes before and after time travel, Zhao Han played with a microscope for the first time and was inevitably a little excited.
He soon saw the tardigrade, how naive he was, and excitedly shouted: "Queen, come and take a look!"
Fei Rulan lay down next to Zhao Han, took a closer look at her glasses, and immediately backed away in fright, exclaiming: "What an ugly monster!"
Zhao Kuanghuan shouted: "I want to see it too!"
The father and son obviously have the same style. Zhao Kuanghuan also found the tardigrade interesting, and he lay there for a long time without being able to move his eyes.
The invention of the microscope made Zhao Han feel very happy: "The crisp autumn air is a good weather for hunting. Li Zicheng hasn't left Beijing yet, right? Ask him to go hunting. Also, Sun Qing will go too. You invented the microscope, so you can accompany me to hunt."
