Infrastructure: I survive in troubled times

Chapter 164 Magical (four more)
"It's more than that! The process of how to calculate it in such a vertical manner can't be preserved if you use an abacus." Hong Lianshuo said as he looked at him with his dark jade-like eyes.

When Cao Huaimin heard the words, he stood up excitedly, paced back and forth, and even jumped and jumped like a child with joy.

"What's the matter, Mr. Cao?" Lin Nanzheng, who was a little crazy, asked worriedly.

"Nothing to be too happy about." Hong Lianshuo smiled at them with lustrous black eyes.

"What's so happy about this?" Lin Nanzheng looked at her puzzled and asked.

"Arithmetic can be recorded like literature and passed on to future generations." Hong Lianshuo said as he looked at them with clear eyes.

"What's the point of learning this? I rarely use it on weekdays?" Lin Nanzheng raised his eyebrows and looked at her. It felt too exaggerated! "Like I collect grain and grass, it takes a lot of money. Where can I use it on weekdays."

"What do you know?" Cao Huaimin looked at him with a sullen face and scolded him, "It's small enough to build a house, build a city wall, or a big wall, without the support of mathematics, what are you building?"

"I'm talking about ordinary people." Lin Nanzheng pursed his lips and defended in a low voice.

Cao Huaimin said regretfully, "Our arithmetic books only leave the results, but not the process. It is hard and laborious to learn."

"Many aspects of life are inseparable from arithmetic, and arithmetic can be said to be a basic subject." Hong Lianshuo's dark pupils reflected the mottled sunlight and looked at them and said, "Arithmetic expressions are really important."

Mathematics is the cornerstone of technological development!Natural sciences require extensive use of mathematical tools.

The use of mathematical expressions has greatly changed the way of accumulation of science and technology, which can prevent many inheritances from being lost.

"This..." Lin Nanzheng scratched his head and said, "I can't feel it."

"Hey! Many techniques of the Mo family have been lost, why?" Hong Lianshuo looked at them with stern eyes and said, "This skilled craftsman has no way to express his wisdom and invention. Due to the lack of a concise and effective way of expression, this skillful craftsman is all through The master and the apprentice can only pass on the experience of oral and oral, to spread and accumulate technology."

"That's why you first go to the library, the imperial study, when you enter the palace." Lin Nanzheng looked at her with wide eyes and said.

"Yes! There is a golden house in the book. Because arithmetic cannot be recorded, this makes the New Dynasty very serious." Hong Lianshuo said very discouraged, "You have read the book, and sometimes you can make mistakes in this writing! Don't say it. Word of mouth spreads by word of mouth, misses the slightest, and goes a thousand miles wrong. This kind of transmission chain is very fragile, this master can bring several apprentices in his life, and how many of them can truly inherit the master's mantle."

"You are not afraid of the disciples of the church, the master starved to death!" Han Chuhu said when he heard the words.

"Yes! The most terrifying thing is to keep one hand. He keeps one hand, and he keeps one hand. In the end, everyone is gone." Hong Lianshuo looked at them helplessly and said, "Can't we keep improving? Can't we go further?"

"Just like in the current war, the transmission route is disconnected, and the technology is directly lost." Hong Lianshuo said happily, "I am very grateful to Hu Bing for not burning the capital of Yandu with a torch." Compared with the books she has read, Yushufang's books are really pitiful.

"Also, it is not conducive to technological innovation, because there are too few people who have the conditions to understand this technology. It is equivalent to a secret technique, and it is almost not disclosed to the public." The branch in Hong Lianshuo's hand tapped the ground lightly. , "With mature arithmetic expressions, some will not be esoteric techniques."

"It's not easy to spread!" Lin Nanzheng looked at her hesitantly when he heard the words and said, "Transcribing is also very troublesome."

"It seems that Uncle Zhong has to not only engrave letters, but also engrave figures and formulas..." Han Chuhu looked at them with a smile and said.

"What do you mean by capturing a tiger?" Cao Huaimin raised his eyes and asked him.

"Printing!" Han Chuhu's light brown eyes looked at them and said, "We all have seals with our own names on them, and we can engrave texts! Bang Bang Bang..." He gestured with his hands, "You can print whatever you want. , font arrangement and combination, ever-changing."

"My God." Cao Huaimin was so shocked that his eyes almost fell out of the window, "This time it can be printed as a book, it's not a problem for everyone."

"Yes!" Han Zhuhu smiled and nodded.

"Is this notice that Mrs. Hong came up with?" Cao Huaimin looked at Hong Lianshuo without blinking and asked with certainty.

"How did Mr. Cao guess it?" Hong Lianshuo looked at him with interest and smiled.

"It's very simple! Has the ability to capture tigers still be brought up until now?" Cao Huaimin looked at her with joy and said.

"After the popularization of printing, everyone can see the process of calculation, and I can find that I have a problem in that number, and I amend it on my basis, revise a new formula, and then go further through printing. A new round of popularization." Hong Lianshuo said excitedly looking at them.

"This math can still break through!" Lin Nanzheng looked at her puzzled and said.

"Of course, this can't be faked at all, Ding is Ding, Mao is Mao." Hong Lianshuo looked at him with eyes as deep as Baoyu and said, "The unremitting efforts of future generations on the basis of ancestors have been making breakthroughs. Progress after progress can be made.”

"Why can't I feel it?" Lin Nanzheng looked at her suspiciously and said.

"How do you say it?" Hong Lianshuo lightly clasped his eyebrows with his index finger, "How can we shoot the farthest arrows on weekdays? These can all be calculated."

"Ah!" Lin Nanzheng looked at her incredulously with wide eyes and said, "How is this possible?"

"Isn't this archery going to go far?" Chen Zhongyuan simply looked at them and said.

"Then you say that the arrow that flew out was shot far in a straight line, or was shot far in an arc?" Hong Lianshuo looked at them with interest and said.

"Isn't this arrow straight?" Jiang Shuisheng stretched out his hand and gestured, "Of course, if there is wind, it won't be sure."

"What about you? Do you think so too?" Hong Lianshuo glanced at the other people.

"Listen to what you mean, Shui Sheng is wrong." Lin Nanzheng judged.

"It's only some arcs that are the farthest." Cao Huaimin directly picked up a branch on the ground and poked a spot on the ground, drawing straight lines and arcs, "The angles are different, and the arcs can be long or short."

"Ah! How is this possible?" Lin Nanzheng gestured, "Really?"

"It's amazing." Chen Zhongyuan stared at them and said.
