When Li Zicheng was going 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, "My lord, 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 added: "Mr. Zhang suggests wearing glasses, but I'm afraid it will damage the prestige of the prince."
"It won't hurt any prestige, you can wear glasses when 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 match the prince with glasses." Zhao Han didn't know what Master Sun did.
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.
Glasses appeared in China in the Yuan Dynasty, but until the end of the Ming Dynasty, glasses were all 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.
However, Sun Yunqiu, with his own power, directly made the glasses that the dignitaries could afford, at the price of cabbage - each pair of glasses only cost two or three cents of silver (one tael equals 100 cents).
This gentleman learned from 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 again, and he doesn't even focus on grinding lenses.
He invented the microscope and kept improving it. Now he conducts research every day and uses a microscope to observe various microorganisms. 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 water bears swimming, and raised his head in a daze 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 very speechless about this, and actually stopped urging, turned around and asked 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 annotated beside it: water bug 21 (tentative name), green body, six-legged
The female officer was already anxiously waiting, and Sun Yunqiu finally got up, went out and clasped his fists and said, "Please wait a long time."
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.
Being brought 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 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 do 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 to studyLooking at his son from the side, he suddenly said: "The spectacle frames should be replaced with better-looking ones. The tortoiseshell tribute from Nanyang Fanbang can be polished into spectacle frames by artisans."
The mother and son were having fun, while Zhao Han was playing with the microscope.
Whatever the emperor wanted, Qintianyuan would send it to him naturally, and they would just make a new one by themselves.
Sun Yunqiu guided his hands and said: "Your Majesty, this is a slide (glass slide). The objects you want to observe must be placed on the slide first"
After traveling through two lifetimes, Zhao Han was playing with a microscope for the first time, and he was inevitably a little excited.
He soon saw the tardigrade, how naive, 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!"
The 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: "The autumn is crisp, and 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 a contribution to inventing the microscope and accompany me to hunt." Easy and easy.?
