Wang Ce passed the county test, government test, and road test easily. Unfortunately, he was still far from the end of the case. His road test score was 67th.
With Wang Ce's current level, even if he returns to Guizhou to take the provincial examination, there is almost no chance of him passing the examination.
Well, there is still some hope of staying in Beijing, because there are a lot of admission places in Shuntian Prefecture, and the strength of the candidates is far less than that of Jiangnan!
But if Wang Ce wants to take the examination in Shuntian Prefecture, Wang Yuan must move here. This approach is easy to attract criticism. Yang Shen's candidates returned to his hometown to take the examination, and Wang Yangming's candidates also returned to their hometown to take the examination. It is just shameless and shameless.
Only then would he choose to immigrate for his son's exams - filial piety is involved, and immigrating would be suspected of betraying the ancestors.
May.
The emperor summoned him.
Zhu Houzhao handed over a transparent object and said with a smile: "Look, Erlang, what is this?"
"Crystal?" Wang Yuan asked doubtfully.
Zhu Houzhao shook his head: "No."
"Transparent glass?" Wang Yuan suddenly couldn't sit still.
Yanshen Town was the largest medicinal jade production base in the Ming Dynasty, which manufactured various kinds of colorful glass.
In the year when Wang Yuan made the telescope, Zhu Houzhao ordered the craftsmen of Yanshen Town to develop transparent glass. It has been thirteen years since then. Although some achievements have been made one after another, the transparency is relatively low. It is now used in astronomy, military and navigation.
The telescopes in China are still mainly made of ground crystal. That is, telescopes for watching football games or for playing are only made of glass.
Wang Yuan couldn't help. Even if it were him, he would just add things randomly and try his luck.
"How is it made?" Wang Yuan asked.
Zhu Houzhao pointed to the kneeling craftsman next to him: "You come and tell."
The craftsman said: "Please tell me, Prince Wang, when making glass, you can make it transparent by adding 'wumingyi'. The common people also discovered it by chance."
Unnamed, Chinese herbal medicine, also known as soil, baldness, and iron sand, is the main component of gold sore medicine. It can also be used in cooking. It can be added when boiling crabs to remove the fishy smell. It is also used to refine tung oil, which can absorb moisture.
It is also used to cut the wick, which will break as soon as it is touched. It can also be used to adjust the color when firing pottery.
Anyway, this is a natural mineral with many uses.
Its later scientific name is called pyrolusite, and its main component is manganese dioxide!
It takes no effort to get it even after trampling through iron shoes. Who would have thought that refining transparent glass requires adding Chinese medicinal materials?
The last time I made steel, the crucible was made of teff stone.
It seems that if progress cannot be made in future inventions, just randomly adding Chinese medicinal materials and cosmetics, maybe there will be some miraculous effect.
Wang Yuan immediately placed an order and paid for the glass, and the craftsmen in Yanshen Town quickly got busy.
Microscope, some people tried it, but gave up soon.
Disciples in the School of Physics, those who play with lenses, all like to look up at the stars, but they seem to have little interest in the microscopic world.
Grinding the lenses of a microscope is more precise than grinding a telescope. The craftsmen at home failed countless times, and Wang Yuan finally made a 60x microscope. This thing can clearly observe fungi, and some large bacteria can also be seen.
But if you want to observe small puddings such as E. coli, the performance of the microscope must continue to improve.
"Husband, what are you messing with?" Huang E came over and asked.
Wang Yuan smiled and said: "Observe the little things and see for yourself."
Under the guidance of Wang Yuan, Huang E began to observe yeast. Unfortunately, the magnification of the microscope was too low, and only densely packed small particles could be seen. There was nothing to appreciate at all, and the bacteria could not even be felt swimming.
It is estimated that this is the reason why physics students are not interested in the microscopic world - the microscope is not two or three hundred times magnified, so it is impossible to see that those "little bugs" are living things!
I still have to keep polishing.
Wang Yuan said: "Amei, I give you a task."
Huang E asked: "What mission?"
Wang Yuan said: "You also understand the principle of lenses. You urge the craftsmen to grind finer glass lenses and magnify the power hundreds of times to observe small things."
"What little thing?" Huang E asked puzzledly.
Wang Yuan said: "Buddha sees a bowl of water with 48,000 insects. I just want to see if there are really 48,000 insects."
Huang E couldn't laugh or cry: "You are so boring, you are looking for such happiness."
Wang Yuan said seriously: "If you use a telescope to observe the moon, you can see that the moon is a round ball with pits. If you use a microscope to observe water, why can't you see forty-eight thousand insects? If not, it only means that our microscope is not powerful enough."
"
Huang E pondered silently and nodded for a long time: "My husband is right!"
As a result, Huang E stopped writing poems and lyrics, let alone submitted articles to the "School of Physics", and started tinkering with microscopes at home all day long.
Now that transparent glass was made, Wang Yuan wanted to make a glass reflector, but he was confused about how to start. He recalled the mirrors in the past and tried to paste a layer of tin foil, but the effect was not as good as a bronze mirror.
Glass mirrors have appeared in Venice, which are also covered with tin foil, but also use mercury.
This kind of mirror is poisonous, and both the maker and daily users will be poisoned to a greater or lesser extent. Before the invention of electrolytic silver plating, glass mirrors could only be made from mercury, and the physics school obviously had not yet begun to touch electricity.
When Wang Yuan was asked to build a mirror, even if he tried thousands of methods, he could never think of using mercury. Because he knew that mercury was poisonous, he would deliberately avoid it, so he could never find the correct answer.
It was dusk again one day, and Wang Yuan used a new microscope with a power of one hundred times to randomly observe various things.
"Master, it's time to eat." Qiyun came over to remind.
Tonight is my turn to spend the night in Xiangxiang's room, where meals have been prepared. Because Wang Yuan has been spending time in the laboratory with Huang Enu, Xiangxiang, being a concubine, is inconvenient to disturb her until the sun is about to set.
, Xiangxiang couldn't bear it anymore, so she sent her maid over to urge her.
Huang E smiled and said: "Husband, go ahead. It's time for me to call Su'er for dinner."
Wang Yuan stood up and said to Qiyun: "Let's go."
Qiyun is about to turn eighteen. She has naturally slightly curly brown-black hair, long eyelashes, and dark gray eyes. She exudes exotic charm all over her body. What's even more rare is that she is so tall, she has already grown to
She is five feet seven inches (1.78 meters tall), has long legs and a slender waist, which can make a man swoon.
"Master is here!" Xiangxiang greeted warmly and pulled Wang Yuan to sit down.
The youngest son, Wang Ji, is already two years old. Because of his mixed race, he is a little different from Han children.
When this kid saw Wang Yuan coming, he ran over to hug his legs and shouted in a sweet voice: "Daddy, give me a hug, give me a hug!"
Wang Yuan smiled and picked up his son and asked, "Have you learned to count?"
Xiangxiang hurriedly said: "Ji'er, count for daddy quickly. What is it once you pass it?"
Wang Ji shouted: "Three!"
Xiangxiang reminded: "Two."
"Hmm." Wang Ji muttered vaguely.
Xiangxiang smiled and said: "Count them together."
Wang Ji said: "One, three, four, five..."
The word "二" is difficult to pronounce, and children obviously don't want to pronounce it.
It wasn't very funny, but Wang Yuan made him laugh out loud.
Qiyun has already taken the two-stringed harp, played, danced, and sang, and entertained Wang Yuan with songs and dances. She and Xiangxiang were women of foreign races, and they had no other ability to marry far away from Beijing, so they could only rely on these methods to maintain their favor, and they had sex.
He is also the most relaxed about things.
When they were in Liaodong, Xia Chan and Xiang Xiang were pregnant one after another, so Wang Yuan took advantage of the situation and moved Qi Yun into their house.
After eating and drinking, Qiyun helped Wang Yuan take a bath, but Xiangxiang was entangled by the child and couldn't leave.
This kid had to sleep with his mother, so Xiangxiang could only sing and coax him slowly. After the child fell asleep, Xiangxiang quietly came to Qiyun's room, blushed and joined in to play a three-person game.
They were the only ones willing to have a threesome, and neither Huang E nor Song Ling'er could lose face.
After rubbing his waist and waking up, Wang Yuan warned himself to be restrained. These two goblins could really eat people.
After breakfast, Wang Yuan rode to the imperial city and gave lessons to the prince as usual every morning.
After the lecture, Wang Yuan was called to the Leopard Room by Zhu Houzhao. When the emperor met, he said: "Erlang, prepare to leave the capital. I am going to recover Daning City!"
