While Li Zicheng was going to visit the Nanjing Night Market, Zhao Han came to the queen's bedroom.

The palace maid took off her coat while serving, and Fei Rulan personally hung up her clothes, walked back and said, "Husband, the prince is short-sighted." ”

"Huh?" Zhao Han thought he had misheard.

Fei Rulan said: "Mr. Zhang of Zhan Shifu said that the prince reads books and likes to read them closely. Mr. Zhang felt bad and put the book away for the prince to read, and the prince said that the handwriting was very blurry. ”

Zhao Han couldn't laugh or cry, and when he thought of his son wearing glasses, he felt very funny and unreal.

Although, many civil officials also wore a pair of glasses on their chests when they met in court.

Fei Rulan also said: "Mr. Zhang suggested wearing glasses, but I am afraid that it will damage the prestige of the prince. ”

"What will damage the prestige, you should wear glasses, choose the best glasses master." Zhao Han said.

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

"Then let Master Sun give the prince glasses." Zhao Han didn't know what Master Sun did.

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

At a young age, he was a master of the Qintian Academy, and it was definitely not derived from his skill in grinding glasses. This old man graduated from Yangzhou University and did not go to the imperial examination, but was directly admitted to the Qintian Academy.

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

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

Glasses were introduced in China during the Yuan Dynasty, but until the end of the Ming Dynasty, glasses were a precious item. The main reason is that it is not easy to grind, and after grinding, it is often not worthy of the degree. At the end of the Ming Dynasty, Western learning spread to the East, and the simple knowledge of optics gradually spread to China, and the glasses making technology finally made a breakthrough, so Qian Qianyi said that glasses are Taixi's things.

And Sun Yunqiu, with his own efforts, directly made the glasses that only high-ranking officials and nobles can afford to use into the price of cabbage - each pair of glasses only costs two or three cents of silver (1 tael equals 100 points).

He studied under Matteo Ricci's disciple Chen Tianqu and mastered some knowledge of mathematics and physics. He also invented a cartridge for grinding lenses, pointed out the difference between presbyopia, farsightedness, and myopia, and prescribed glasses according to the actual situation of the patient. He even wrote the book "History of Mirrors", which made all the methods of making glasses public, which eventually caused the cost of glasses to plummet.

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

By the way, Sun Yunqiu can also make self-striking bells.

Sun Yunqiu, who is in this time and space, will definitely not go to collect medicine again, and not even just focus on polishing lenses.

He invented the microscope and improved it, and now he conducts research every day, using a microscope to observe various microorganisms. On the Qintian Academy's side, it even plans to set up a separate "microscopic pavilion" for researchers to explore the microscopic world.

"Wenyu, Your Majesty summons!" Fang Yizhi personally shouted.

Sun Yunqiu, who had just invented the microscope slide, was watching the cute tardigrades swimming, and looked up blankly when he heard this: "What did Your Majesty call me to do?" ”

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

"Wait a minute," Sun Yunqiu said, "The lenses I polished a few days ago can see the microworms more clearly, and today I found a new kind of water worm." When I finished my observations, I went to the palace to see Your Majesty. ”

Fang Yizhi was speechless about this, and he really stopped urging, turned around and asked the female officer to wait.

Sun Yunqiu continued to toss in front of the microscope, and then took a pen and began to paint, drawing the whole picture of the tardigrade from different angles, and also annotated on the side: Water Worm 21 (tentative name), body green, six-legged......

The female officer was already waiting anxiously, Sun Yunqiu finally got up, went out and hugged his fists and said, "There is a long wait." ”

As soon as this guy left, the researcher next to him hurriedly ran to occupy the microscope. The lens of this microscope is a super high multiple of the latest polishing, and it is the only one in the entire Qintian Courtyard, and they are all waiting in line to see the strangeness.

was brought into the palace in a daze, Sun Yunqiu didn't pay attention to the scenery along the way at all, and he still had something under the microscope in his mind.

"Your Majesty, Niangniang, Prince, Master Sun brings."

Sun Yunqiu finally came back to his senses and hurriedly stepped forward to pay respects.

Zhao Han didn't talk about myopia, but asked, "I heard that you invented a microscope, how did you make it?" ”

Sun Yunqiu replied: "Back to Your Majesty, although the minister's ancestral home is Wujiang County, because his uncle is doing business in Hangzhou, he has lived in Hangzhou with his uncle since he was a child. Eighty percent of the world's glasses come from the hands of Hangzhou mirror craftsmen, and the minister is quite curious about the glasses, so he stands by all day to watch them grind. ”

Later, I entered the school and learned geometry and physics, and Fang knew the true meaning of optics. When he was in middle school, he began to polish his own lenses, and he always felt that it was not easy to polish the lenses, so he pondered the invention of the car. In fact, it is not an invention, the principle comes from the water orange, which has existed since ancient times. ”

When he was studying in college, he first learned to make clairvoyant mirrors, and later made kaleidoscopes, luminous mirrors and other objects. I thought that the clairvoyant mirror can see extremely distant things, why can't I polish a set of lenses to see the very close and extremely small things? That's how the microscope came in. ”

"Great goodness!" Zhao Han praised.

Sun Yunqiu said: "Your Majesty has praised it, the microscope is of little use, it can only observe some small insects to satisfy the curiosity of the scholars of the Qintian Academy. ”

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

"Small bugs cause coughing?" Sun Yunqiu couldn't keep up with the emperor's rhythm.

Zhao Han continued: "When you come into contact with patients and phlegm, you must wear a mask, which is the kind of cotton mask to protect against the plague. When observing, wash the contact with boiling water, and wash your hands repeatedly. By the way, it is best to wear gloves and soak them in boiling water afterwards. ”

The emperor had a task, and of course Sun Yunqiu did not dare to refuse: "The minister obeys the order." ”

Fei Rulan reminded beside her: "Your Majesty, let's talk about the prince first." ”

Zhao Han pointed at Zhao Kuanghuan: "My son is short-sighted, and I bother Sun Qing to wear a pair of glasses." ”

Sun Yunqiu said: "Your Majesty, the minister wants to go home and get the things for optometry." ”

"Go ahead." Zhao Han nodded.

Sun Yunqiu took the royal carriage, went back quickly, and got a set of optometry equipment.

He first broke open the prince's eyelids and used a magnifying glass to observe the condition of his eyes. Then he erected a cardboard, on which were written the word "A" in different directions and sizes, and asked the prince to point out the specific direction blindfolded.

Fei Rulan couldn't understand it, and after Sun Yunqiu was done, she asked curiously, "What is this doing?" ”

Sun Yunqiu replied: "Back to Niangniang, the minister thinks that the eye is a convex lens, and for some reason the focus is shifted forward, so he can't see things clearly, and he can adjust the focus by making glasses with a concave lens." And because the focus of myopia is different for each person, when wearing glasses, it is necessary to measure how much the focus has changed. The word 'A' on this cardboard is of different sizes. Each size represents a focal point and thus a different concave lens. ”

"I see, there is a master of Laosun." Fei Rulan smiled, but the more she listened, the more confused she became.

Zhao Han suddenly said: "You guess that the eye is a convex lens, why don't you confirm this conjecture?" ”

Sun Yunqiu was stunned: "Minister...... How can this be confirmed? ”

Zhao Han said: "You can go to the butcher and dig out the eyes of the pig you just killed to observe." Or, simply go to medical school, where autopsies are common. ”

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

The Ziyang Medical College, which originated from Jiangxi Gesoshan, when Zhao Han's territory was still only in Jiangxi, he kept throwing the corpses of the enemy for autopsy.

Nowadays, detailed human bone diagrams, muscle diagrams, blood vessel diagrams, etc., have been drawn by the doctors of the Ziyang School. However, the dissection process was too disgusting, and it violated traditional customs, causing the Ziyang faction to be spurned by traditional doctors, and there were even rumors that Dr. Gesoshan liked to eat people.

In the ancestral court 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, spurned is spurned, and the medical research results of the Ziyang School have been quietly studied by traditional doctors. No matter what kind of famous doctor they were, they would secretly collect those human anatomy diagrams, and only let the disciples in the room study them privately.

A few days later.

After Sun Yunqiu's fine polishing, 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 instantly smiled from ear to ear.

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

An emperor with glasses, sitting on the throne of Jinluan, that situation is really a bit dramatic.

Perhaps it will be similar to Emperor Yongzheng, Yongzheng has 35 pairs of glasses, with different styles and materials. After washing up every morning, the first thing Yongzheng does is to think about which pair of glasses to wear today.

What "Step by Step", and what "The Legend of Zhen Huan", are not filmed enough to restore history, and they don't give the fourth master a whole pair of glasses to wear.

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

Fei Rulan looked at her son beside her, and suddenly said: "The glasses frame should be changed to a better look, the tortoiseshell tribute from Nanyang Fanbang can be polished into a glasses frame by craftsmen." ”

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

If the emperor wanted something, Qintianyuan naturally sent it to them, and they made a new one by themselves.

Sun Yunqiu instructed him by hand: "Your Majesty, this is a slide (slide), and if you want to observe something, you must first place it on the slide......

After two lifetimes, Zhao Han played with a microscope for the first time, and he was inevitably a little excited.

He soon saw the water bear, how cute it was, and shouted excitedly: "The queen come and see!" ”

Fei Rulan lay beside Zhao Han, took a closer look at her glasses, and suddenly retreated in fright, exclaiming: "What an ugly monster!" ”

Zhao Kuanghuan shouted: "I want to see it too!" ”

The father and son are obviously in the same style, and Zhao Kuanghuan also thinks the tardigrades are interesting, and he can't take his eyes off lying there for a long time.

The invention of the microscope made Zhao Han feel very happy: "Autumn is high and cool, and it is a good weather for hunting. Li Zicheng hasn't left Beijing yet, right? Call him to go hunting. Also, Sun Qing will also go, you have made a contribution to the invention of the microscope, and it is easy to accompany me to hunt. ”
