Chapter 150 The Glass Burned Out
"I wonder what questions Dr. Li wants to discuss with me?" Lin Xuan asked.
"I got a question a few days ago, and I haven't figured out the result after studying it for a few days. I want to ask Lord Hou to take a look." Li Chunfeng said.
Lin Xuan breathed a sigh of relief when he heard that it was a solution to the problem, and said with a smile: "Tell me the problem."
"Now there is a log buried in the wall. I don't know the size. I saw it. It is one inch deep and one foot long. What is the diameter?" Li Chunfeng said.
Lin Xuan understands the title, which means: there is a column of wood buried in the wall.I don't know its width, so I saw it with a saw (along the cross-section). When the depth is measured to be one inch, the width of the saw is one foot. What is the diameter of the wood?
This question involves the Pythagorean theorem, of course Lin Xuan can solve it, but even Li Chunfeng can't understand his methods of solving the problem.
"Dr. Li, this question is very difficult. I'm afraid I won't be able to solve it in a short time!" Lin Xuan said apologetically.
He could solve it, but who knows if Li Chunfeng will ask some more difficult questions in the future.
Rather than being stumped later, it is better not to solve it at the beginning.
Li Chunfeng felt that his arithmetic ability was not good, so naturally he would not come here in the future.
"This problem is really difficult. It's normal for Lord Hou to be unable to solve it in a short time. The two of us can discuss it. Maybe we can solve this problem with the strength of the two of us!" Li Chunfeng said .
"Ahem... I think arithmetic is just a small way, and Dr. Li should do something more meaningful!" Lin Xuan said.
At first he thought he could send Li Chunfeng away, but he didn't expect Li Chunfeng to discuss with him.
"Isn't it very meaningful to solve these arithmetic problems and then write a book for future generations?" Li Chunfeng said puzzled.
Lin Xuan was speechless, no wonder you left so many books on arithmetic in history.
"Didn't Dr. Li write to His Majesty in the first year of Zhenguan, putting forward 18 opinions on the "Wuyin Yuanli", why didn't he create a new calendar?" Lin Xuan said with a smile.
Li Chunfeng's eyes lit up, and he counted. Everyone knows the calendar. If he can rewrite a new calendar, he will definitely be famous in history.
"Thank you Lord Hou for your guidance!" Li Chunfeng said.
Li Chunfeng had lost his mind now, and was thinking about arithmetic. After exchanging pleasantries with Lin Xuan for a while, he offered to leave.
After sending Li Chunfeng away, Lin Xuan breathed a sigh of relief.
Historically, Li Chunfeng made long-term observations and calculations.After Li Zhi succeeded to the throne, he proposed to rebuild the new calendar.
Now the time is so long ahead of time, I don't know if he can write it.
But it's okay to think about it, it's nothing more than spending a little more time.
As long as Li Chunfeng doesn't bother him, he can do whatever he likes.
……
After Kong Yingda left the Lin family, the more she thought about it, the more she felt that punctuation marks were very important.
After thinking about it carefully, he told the coachman to go to the palace.
Li Shimin was reviewing the memorial, and he was a little puzzled when he heard Li Mu report that Kong Yingda asked to see him.
If the old man doesn't teach him well, why come to him?
"Let him in!" Li Shimin said.
"Sir, see Your Majesty!" Kong Yingda bowed his hands and saluted.
Li Shimin smiled and said: "Excuse me, Kong Aiqing came to see me, does it mean that the crown prince is not listening to discipline again?"
Li Chengqian's first teacher was the famous 'Prince Killer' Li Gang in history.
When Li Gang was in the Sui Dynasty, he was the teacher of Prince Yang Yong, and after the establishment of the Tang Dynasty, he became the teacher of Li Jiancheng.
After Li Shimin succeeded to the throne, he was appointed as Li Chengqian's teacher.
Three emperors in a row chose him to teach the prince, which shows that his ability is very outstanding.
However, Li Gang had bad luck and a lot of fate.
None of the princes he taught sat on the throne.
Li Gang died last year, and Li Shimin asked Kong Yingda to teach Li Chengqian.
Kong Yingda complained to Li Shimin many times about Li Chengqian, and Li Shimin thought he was here to sue again this time.
"Your Majesty, the prince has studied very hard recently, and managed the Chang'an Mansion in an orderly manner, without fault!" Kong Yingda said.
"Then why is Kong Aiqing here?" Li Shimin asked with some doubts.
Kong Yingda said: "Your Majesty, I'm here this time to talk about sentence breaks."
"Sentencing? I don't know what's the problem with severing sentences?" Li Shimin asked suspiciously.
Kong Yingda said: "Your Majesty, the current books are all in one piece. Different sentences have different meanings, which will make people misinterpret the meaning of the book!"
Of course Li Shimin knew this, but hasn't it been like this since ancient times!
"Could Aiqing have a solution to this matter?" Li Shimin asked.
Kong Yingda said: "I have no choice, but the Marquis of Jingyang County has a way."
Kong Yingda took out the punctuation marks written by Lin Xuan and explained it to Li Shimin.
"Your Majesty, having punctuation marks is not only beneficial for ordinary reading, it is also very helpful to those poor children who do not have a famous teacher to teach them. I request to rewrite the book and add punctuation marks." Kong Yingda said.
Li Shimin also saw the benefits of punctuation marks. With this punctuation mark, it would be much easier for children from poor families to study, and more talents could emerge in this way.
"Kong Aiqing, this matter is a major event that benefits the country and the people, and I will call people to help you complete it!" Li Shimin said.
"Thank you, Your Majesty, but this matter requires the cooperation of the Bookmaking Bureau of the Ministry of Rites." Kong Yingda said.
He can add punctuation marks to the book, but he also needs to print the book and spread it.
Li Shimin had a headache. If he wanted to add punctuation marks, the previous engraving would naturally be unusable, so he had to re-engraving. (The technique of engraving and printing can only be confirmed to have existed ten years before Zhenguan. It is uncertain when it was invented. Here it is assumed that it has already existed. You don’t have to be serious.)
The cost of re-engraving all the books will undoubtedly be very high.
Since the increase of commercial tax and the sale of salt, his financial pressure has been reduced.
But the commercial tax and salt, after all, it has not been long since it started, and there are so many places to spend money, he has no money to spend on re-engraving.
"Kong Aiqing, rewrite the book first, and when your book is finished, I will ask Zao Shuju to re-engrave it." Li Shimin said.
No matter what, Kong Yingda should be appeased first.
"I am a scholar on behalf of the world, thank you Your Majesty!"
Seeing that the goal was achieved, Kong Yingda left happily.
Li Shimin rubbed his head and said, "Li Mu, send someone to call Lin Xuan to me!"
……
Not long after Lin Xuan sent Li Chunfeng away, Xu Guangfu came to look for him with a happy face.
Xu Guangfu cupped his hands and said with a smile: "Congratulations, Lord Marquis!"
Lin Xuan waved his hand and said, "I see you look happy, don't you just come to congratulate me?"
"Master Hou, the colored glaze has burned out!" Xu Guangfu said excitedly.
"Really?"
Lin Xuan was a little surprised. Xu Guangfu said the day before yesterday that there were too many impurities and it would take some time. He didn't expect it to be finished so soon.
"Thanks to Master Hou's suggestion, I asked the workers to increase the temperature and burn it for a longer time, and it actually burned out!" Xu Guangfu said with a smile.
"Did you bring the finished product?" Lin Xuan wanted to see if there was a big difference between the glass of today and the glass of later generations.
"Master Hou, it was just an experiment at the beginning, and the shape of the burnt ones was particularly ugly. The younger ones were not brought over, and the younger ones have already asked them to start a new kiln. It won't be long before Master Hou will see them." Xu Guangfu said.
"Go, take me to see!" Lin Xuan said.
The burning of the glass is not only related to his building a house, but also means that he can make money.
Since the construction of the house started, money has been spent every day like running water.
His family's current money may not be enough to spend all of it.
Now that the glass is out, there will be no shortage of money in the future.
But the glass is made of sand, and it costs nothing at all.
Of course, because of the increase in glass, it must not be as valuable as before.
But it shouldn't be a problem if you sell them for a few bucks.
Datang is saturated, and there are surrounding countries.
Although Li Shimin took [-]%, he only got [-]%, which is also a huge fortune.
