One day, Han Du was accompanying An Qing to look after his son in the yard. The two or three-year-old child is the time when people are so energetic that they are bored by dogs. He was pestered by his son and played with him just now, which made Han Du, who was not yet thirty years old,
Even at this age, he felt tired, weak, and exhausted. Fortunately, a maid drew the kid's attention away, allowing Han Du to escape.
Lying lazily on the chair, Han Du turned his head to look at An Qing, who was drinking tea elegantly, and said, "Should we find an enlightenment teacher for Zhong'er? It's not an option for him to play like this all day long."
The main reason was that he kept pestering me all day long, and my body was a little overwhelmed. Han Du silently cursed in his stomach.
An Qing glanced at Han Du with a smile on his face, as if thinking of Han Du's miserable state being tortured by his son, he burst out laughing, leaning forward and back with great joy.
Han Du didn't know what An Qing was laughing at, he just felt that she was having bad intentions. He couldn't help but darken his face and said seriously: "I'm serious about you, why are you laughing?"
"No, no." An Qing couldn't help but glance at Han Du again, waving his hands and shaking his head in denial.
After finally calming down, An Qing smiled softly and said: "Is it too early for enlightenment now? I remember when I was a child, I was six or seven years old, and my father asked my husband to enlighten me. My son is still young now,
Let him play for two more years." ??
That's two more years of playing with me. Handu couldn't help but complain in his heart.
No, I have to find something for my son to do, otherwise he will torture me until I have a nervous breakdown? Han Du's mind is running rapidly, thinking hard.
Suddenly, Han Du came up with an idea: "My son doesn't need to be enlightened yet, but we can also let him learn to read first."
"How can I read without enlightenment?" An Qing was a little unable to understand what Han Du meant, but she knew that Han Du's ideas were always unconstrained and unimaginable, and he imagined things that ordinary people would never think of.
So with a bit of curiosity, his beautiful big eyes flashed and he looked at Han Du.
Han Du quickly gestured with his hands, "Look, doesn't my son like all kinds of animals? We can draw various animal patterns on the paper, such as chickens, ducks, geese, dogs and cats, and add text. In this way, my son will read
When these chickens, ducks and geese play together, they will subconsciously remember the relevant words. As long as we teach them intentionally, we might be able to help them learn to read early."
"Is this useful?" An Qing heard such a novel thing for the first time and felt a little incredible.
"Can you please remove it? It must be useful." Han Du turned over and stood up, ready to do it as soon as he thought of it. Paper is easy to find, and Han Du planned to use high-quality rice paper. Then he found a few painters to draw the appearance of various objects.
Come down.
Before Han Du could do anything, the maid came to report.
"Master Hou, Mr. Fang is here."
Mr. Fang in the maid's mouth is Fang Xiaoru. This guy is becoming more and more refined now, and his movements have the demeanor of a Confucian master. The maids in the mansion do not dare to call him by his first name, so they address him as Mr. Fang.
"Fang Xiaoru? What is he doing here?" Han Du asked subconsciously.
Seeing the embarrassment on the maid's face, Han Du also realized that his asking was in vain. Due to the close relationship between the two, Han Du had already ordered the people in the house that as long as Fang Xiaoru came to him, there was no need to ask the reason or inform him.
, you can let Fang Xiaoru come in directly.
"Where are they? In the front hall?" After Han Du came to his senses, he continued to ask.
"Yes." Seeing that the Marquis did not blame her, the maid covered her mouth and smiled a few times, then nodded and replied.
"I'll go see what's going on first, and then I'll come back and continue to think about how to get these things for my son." This was what Han Du said back to Anqing. After that, he strode in front of the maid towards the front hall.
go.
An Qing ignored Han Du and just smiled and nodded when he turned around. After Han Du left, An Qing felt that she had had enough, so she got up and walked towards where her son was playing.
Han Du came to the front hall, and as soon as he entered the door, he saw Fang Xiaoru sitting upright and drinking tea.
The two of them were so familiar that Han Du didn't even say hello to him. Instead, he walked a few steps to Fang Xiaoru and sat down next to him. He sat down on the chair and let out a groan from his nose.
>
"I discovered that the most comfortable thing is to be able to sit down. Even sitting for a while is much better than standing and running around with my son."
Fang Xiaoru didn't even raise his head. He was still drinking the tea in his hand and casually responded: "It's pity for the parents in the world. This is why I listen to my father."
After saying that, Fang Xiaoru raised his eyes and looked at Han Du: "But this is not why I came to you today."
Han Du slumped on the chair, feeling that the pain all over his body had been relieved a lot, and he felt so comfortable that he wanted to lie down like this. He weakly raised his eyelids, glanced at Fang Xiaoru, sighed and said, "What do you want to see me for?"
,Speak directly.”
Seeing Han Du's attitude, Fang Xiaoru suddenly became dissatisfied. The teacup that was about to be brought to his mouth was put down heavily on the table. He said angrily: "You are such a noble person who forgets things. Don't you?
Do you remember that you are still the vice-president of the academy?"
"I remember, why is it that the academy is short of money again? Didn't I give all the glass to the academy last time? Why is it not enough?" When Han Du heard the word academy, he sat upright in excitement.
He looked nervous and saw Fang Xiaoru.
If the profit from the glass workshop is not enough to maintain the academy, then Han Du really can't think of any good way except using his own money to subsidize it.
No, it's not impossible.
Isn't Lao Zhu the academy's judge? Strictly speaking, this academy belongs to him. He should contribute a lot, and he must contribute a big share.
Thinking about Lao Zhu's annual income of more than 40 million yuan, Han Du couldn't help but feel a little moved. With so much money, if Lao Zhu slipped a little bit between his fingers, it would be enough to cover the expenses of the academy.
"The academy is not short of money for the time being." Fang Xiaoru's words made Han Du look much better.
He returned to his indifferent look and asked casually: "What's going on?"
"It's because some gentlemen and some students in the academy came up with something together and wanted you to see it." Fang Xiaoru picked up the teacup again and took a sip without any restraint, carefully tasting Handu's good tea.
"What is it?" Han Du rested his left arm on the armrest of the chair, leaned against Fang Xiaoru, and asked closely: "Isn't Mr. Xue in the academy? He was the former Minister of the Ministry of Industry, and he has never seen anything in his life?"
"
Fang Xiaoru sat on Han Du's left side and leaned closer and chuckled: "It's Mr. Xue who asked me to ask you to take a look."
"Oh?" Han Du touched it. Since it was something that even Xue Xiang was not sure about, it made Han Du a little curious.
"Then let's go, let's go and take a look now." Han Du is quite concerned about the academy, and he has been teaching a group of students for so long, so he also wants to see what they can make.
Han Du followed Fang Xiaoru to the academy.
After so many years of continuous construction, the various buildings in front of the academy have all been completed. Behind the academy, only a general framework has been built. Because of this, the place seems very empty, and the students
When doing experiments, I like to do them at the back of the academy.
After all, whether it is physics or chemistry experiments, fire is required. If it is done in the front building, it will be bad if the building is burned down.
Han Du pushed the door open and entered a house with large sorghum pillars. Looking at the steel frame one foot high, he felt that this thing seemed familiar.
Several people were gathered around the shelf and concentrating on discussing something. Even the sound of Han Du pushing the door open was not heard by them.
"What is this? Who made it?" Han Du walked forward and looked at the shelf carefully.
"Mr. Han is here." Several people stood up after hearing this, and one of them nodded and greeted Han Du with a smile.
"So it's you, Sun Xian. What, is this what you created? What's its use?" Although Han Du looked familiar at this thing, he couldn't remember it for a while. Instead of thinking about it,
I have been thinking hard here, so it would be simpler and more direct to ask Sun Xian directly.
Sun Xian was one of the first scholars to come to the academy to study, and he was not very interested in the Four Books and Five Classics. He was able to pass the exam simply because he was smart enough. On the contrary, he was interested in exploring complex matters such as natural laws and techniques.
He was very interested in learning. When he heard about mathematics, physics and chemistry that the academy was going to teach, he was the first to come to the academy to study without hesitation.
The reason why Han Du knows Sun Xian deeply is because he is very good at mechanics. Among all the students, he can at least be ranked in the top three. Being able to be firmly ranked in the top three means that he is almost the best in mechanics among the students.
You are a good person. Because even if you get first place once, there is no guarantee that he will get first place again next time.
In the last spring, Sun Xian was naturally among the best, ranking third in the second class. But later, because he was accused of cheating, most of the students in the academy gave up their official positions and became teachers in the academy.
Sun Xian had no interest in taking the imperial examination and becoming an official, so he was overjoyed to be able to stay in the academy, because not only could he continue to study his favorite mechanics, but he could also teach and educate people and support his family. It could be said that he was blessed with three blessings.
Sun Xian rubbed his hands and felt a little reserved in front of Han Du. However, he knew that when Han Du was in the academy, he didn't have any airs of being a prince. He smiled and explained to Han Du: "A student taught by the student is more concerned about the pulley set.
He was interested. Then he talked about an idea, whether he could use a pulley block to make something that could carry large items. Then the student took someone to try it, and he didn't expect that it could actually be made."
Of course, Han Du didn't wait for Sun Xian to finish speaking, and he hurriedly answered for him in his heart. Even Han Du felt a little regretful that he didn't think of this.
I have seen it more than once. On the pier outside the north gate, there are endless scenes of cargo ships loading and unloading goods. All goods can only be carried up or unloaded manually. It is time-consuming, labor-intensive, and very costly.
Said, and the efficiency is extremely low.
You must know that boarding the ship is not easy. Usually, a movable wooden board is put between the plank road and the ship. Even if people walk on it with bare hands, they may fall into the sea. Not to mention that the people loading and unloading have to carry heavy loads.
of goods, so they could only move the goods one step at a time and carefully.
Thinking of the increasingly prosperous overseas trade of Ming Dynasty, the ships entering the dock every day are like blocking out the sun. The number of goods that need to be loaded and unloaded every day is an extremely huge number. If we can really continue to improve this thing, we can
To meet the cargo ship loading and unloading requirements, Han Du seemed to see a huge amount of money coming towards him.
"Okay, good stuff." Han Du patted Sun Xian on the shoulder and praised loudly.
Seeing that Han Du was so happy, Sun Xian obviously agreed with what he had made. He smiled and nodded in agreement. He even deliberately bent down and lowered his body when Han Du reached out to pat his shoulder, so that Han Du could pat him more comfortably.
Although Han Du was about the same age as Sun Xian, in this era where teachers were respected, although Han Du did not accept him as a disciple, Sun Xian himself was extremely grateful to Han Du and treated him as a teacher.
"Sir, why don't you let the students demonstrate it for you?" Seeing that Han Du was very interested, Sun Xian suggested at the right time.
Han Du nodded repeatedly, and he also wanted to see how well they made this thing: "Okay, then let's wait and see how effective this thing of yours is."
"Just watch it, sir." Sun Xian smiled and bowed slightly to Han Du, turned around and said to the people next to the shelf: "Quick, get ready, let's demonstrate it to sir."
Several people have obviously tried it before, and now they are familiar with it and feel no stranger to using this rack again.
I saw one person hooking a huge iron hook on a stone tied up with a large hemp rope. Then only one person stood up and stretched out his hand to pull the rope, and the stone was easily pulled up.
This kind of thing is not uncommon. Han Du once showed it in front of Lao Zhu. The important thing is something else. After the stone was lifted, the man started to pull up another one.
The ropes and stones did not continue to be hoisted, but began to move parallel along the shelf.
"Okay!" Seeing this scene, Han Du clapped his hands happily.
Although the thing made by Sun Xian is crude, it completely conforms to Han Du's idea. As long as it is improved a little more, it will be a qualified loading and unloading tool.
Sun Xian returned to Han Du and replied with a smile: "It's good that you are happy, sir. The students are afraid that they will insult you because they are not good at their studies."
"No, you really did a good job." Han Du first praised Sun Xian affirmatively, and then asked: "How much weight can this thing lift?"
"One thousand pounds is definitely no problem." Sun Xian replied immediately.
"For a thousand pounds, it's a little less," Han Du said to himself noncommittally.
One thousand kilograms is almost equivalent to the amount that ten people can carry once, and the efficiency is much faster than that of people. After all, for this tool, moving goods is just one step at a time, but for people, it takes ten people
Carry the goods on your back bit by bit.
Sun Xian heard Han Du's words and quickly explained: "Sir, if this thing is made stronger, it can still lift two thousand kilograms."
Two thousand kilograms is barely enough. Han Du made a slight calculation in his mind, and did not continue to struggle with this issue. Instead, he said: "But your thing is still too small. If you want to really use it, you have to build it."
Just make it bigger."
Still young? Sun Xian looked back at the one-foot-tall shelf and didn't know what to say. In fact, he built this thing just on a whim, just to test his students' ideas, and he didn't have any idea himself.
I hope I can do something with this thing.
"How many do we need to make?" Sun Xian was a little unsure about Han Du's intentions and couldn't help but ask in a low voice.
"Let's not talk about this for now. Let's talk about the ownership of this thing first." Han Du looked at Sun Xian with a smile, and his enthusiastic attitude made Sun Xian shiver.
"What, where does it belong? If you want it, sir, just take it." Sun Xian was extremely generous and casually promised to let Han Du take it away.
Han Du glanced at Sun Xian meaningfully, a little helpless at his generosity. He didn't know the value of this thing, let alone how much gold and silver he had thrown away with his casual words.
Han Du felt that it was necessary to teach this dull student a lesson, "Don't you know how much this thing is worth? Your family is not rich, so why don't you even ask a question and just let us take it?
Walk?"
"This is just a shelf made of fine steel. How much is it worth?" Sun Xian said nonchalantly. In his opinion, this thing is just steel and is a bit more expensive, but it was Tuolinmo who helped him get it.
Yes, it only cost less than thirty guan.
Thirty guan is a huge amount of money for ordinary people, but Sun Xian's monthly salary in the academy is ten guan, which is only his monthly salary for three months.
"You'd better first listen to how much money I'm willing to pay." Han Du said with a faint smile.
"Sir, just take it and use it. It really doesn't cost anything." Sun Xian refused as always.
Han Du ignored Sun Xian's words, glanced at the stone that was still in the air, turned to Sun Xian and asked doubtfully: "I saw that after your stone was lifted just now, even if you loosened the rope, it didn't move.
Luoluo, is there any mechanism here?"
"Yes." Sun Xian answered honestly, "The student added a clip to the pulley block. Normally, this clip will not have the slightest impact on the rope. But once something is hung up, it will be hit by a heavy object like this.
Just pull the clamp so that the rope can only be lifted up and cannot be lowered. After the weight is removed, the clamp will naturally loosen."
"Yes, the idea is very clever." Han Du glanced at Sun Xian appreciatively, nodded and said:
"Although your thing is good, it still has some shortcomings compared to what I imagined. But the overall idea is right, so I am willing to give you five thousand guan to buy all the technology of your thing. What do you think?
