"So I still have to strengthen mathematics, physics and chemistry, I didn't learn much in this area when I was a child, and there is a problem with the knowledge structure......"

Of course, Lu Ping knew in his heart that he was able to be here completely because of fate, not because Li Yiming took a fancy to him, or which chief felt that he was particularly capable.

On Li Yiming's side, there will definitely be an improvement in the knowledge of vision, but now it seems that the underlying foundation is still weak.

Li Yiming glanced at him: "It's not a matter of learning less. It's a question of how you think of your stock of knowledge, how we improve ourselves, and where you put your limited energy. ”

Lupin's face was hot.

Li Yiming didn't want to torture him, so he drew a drawing with a pen and handed it to Lu Ping: "What do you think this is?"

Lupin took it.

The paper is a river, and there is a boat in the river, and there is a high mast in the middle of the boat, and two small arc-shaped arrows are drawn on both sides of the boat.

The diagram is very simple, and you can see that it is a rotation.

"It's .... Special ships?"

Li Yiming said softly: "This is a device that can use the power of the river to automatically drill into the ground in the middle of the river, without electricity or manpower. ”

Lu Ping was shocked, it can be like this, it is very useful to drill in the river, but Li Yiming has many magical inventions, and this one is not bad.

"Good stuff!"

"Yes, it's a good thing, then you can guess," Li Yiming looked at him, "Guess which poem it comes from?"

Lupin stared at the paper, could this thing have originated from a poem?

I thought it was from the spinning top you played!

He scraped hundreds of poems in his mind, and finally sighed and shook his head in frustration: "I can't guess." ”

Li Yiming snorted softly: "You know the poem "Yedu unmanned boat self-restraint, right?"

"Is this it?" Lupin was startled.

"Have you memorized it?"

How could such a famous poem Lupin not know: "This is the Chuzhou West Stream from Wei Yingwu, which grows on the edge of the lonely grass stream, and there are yellow orioles singing in the deep trees." The spring tide brings rain and comes in a hurry, and the wild ferry is unmanned and self-controlled. ”

"I have a good memory, so have you ever seen the phenomenon of a boat crossing himself?"

Lupin thought about it and nodded.

"Have you ever seen a boat spinning in the middle of the river?"

Lupin nodded again: "It has something to do with the current, and the boat will naturally be horizontal when the water is around." ”

Look at the picture on this piece of paper again: "Really?"

The boat spins, and there is a drill bit in the middle, and it can go to the bottom of the river? If you keep spinning like this, it is definitely not an ordinary boat.

"I showed you that you don't even know if you can do it. ”

Li Yiming sighed, "Of course you can, and the cost is very low, which is actually similar to the power unit I said in the afternoon." ”

"Oh...."

"In the old society, cultural people had a high status, they were supported by others, and they could write a few lines of poetry in exchange for food and drink, but their production was only for entertainment, and had little to do with the social productive forces and the national strength of the country. We can't do this now, learning knowledge is sour and smelly, and we engineers can solve this problem very easily, but they may not think of it. ”

Lu Ping couldn't laugh at all, Wei Yingwu himself definitely didn't expect to get this thing, but what kind of productivity and knowledge system was it at that time?

"Knowledge needs to be accessible, otherwise it will be difficult to come in handy. ”

Lu Ping smiled helplessly: "If we all use this way in teaching in the future, it will be different... Cultivate more people like you who can think about problems. ”

He already knew that Li Yiming wanted to create a completely new set of education in China, re-education for all, a new form, and a new classroom.

At that time, people who did not study both arts and sciences were not qualified to compile textbooks, and it would be difficult for them to even watch the door in the classroom.

"I know, so don't say that you are old, there are countless knowledge hidden in the ancient works you memorize by yourself, and those things are not used to move yourself, nor are they used to prove that you are literate. ”

"To study natural and social phenomena?"

"It's not just research, it's about ideas. You have to be good at asking questions, if you ask them, someone will naturally solve them, and you think that only I can draw this thing?"

Lupin really wants to ask who else you say.

"There must be a lot, but people who can paint may not want to do this, just like you, you can do a lot of things, but you may not want to, because you don't have this need yourself, you are actually taken care of too well by the state. ”

“......”

"Although the knowledge network will be built across the country soon, it will take a while, will your brain be idle during this time?"

Li Yiming walked to the map as he spoke, picked up the bamboo strip and pointed seven or eight places on it: "There are rivers everywhere, and it is worth thinking about how to make river transportation convenient." If we want to change the way of the moat, is it enough to just build a bridge?"

“...... Use iron cables to erect power lines along the river. ”

Lu Pin said softly, this has already started experiments, it seems to be really feasible, but I am worried that the materials will not be up to standard.

But the matter of materials can also be solved by a single Ming.

He glanced at Li Yiming, not sure if he was tired from thinking too much.

"That's by the river, in the middle of the river?"

"In the middle of the river... You have to use boats, right? Or build a reservoir. ”

"Between the white emperor and the clouds, thousands of miles of Jiangling will be returned in one day. The apes on both sides of the strait could not stop crying, and the light boat had already crossed the ten thousand mountains. Do you say that Li Bai really arrived in Jiangling in one day?" Li Yiming turned his head to look at Lu Ping.

"I don't know, probably. The Three Gorges side is really dangerous, and the water flow is very fast..."Lu Ping made Li Yiming panic, he really didn't think about these problems.

How did I miss out on so much to think about!

Lupin was annoyed.

"The White Emperor City is in Fengjie, Chongqing, 1,200 miles away from Jiangling, it is impossible to sail at night, he sets off in the morning, counting him 12 hours, 1 hour and 50 kilometers, this speed is too fast on the river. ”

"Can't?"

"Yes, of course, but the boatman should also pay attention to safety, the section of the Three Gorges may be faster, why should it be so fast after the Three Gorges, he is a poet, of course he has to see the scenery, the boat runs so fast, even if he doesn't get seasick, he has to eat, even if he doesn't even eat, he has to drink, was there a hot pot in Chongqing at that time?"

Lupin almost bent over.

"I don't know, hot pot..."

"It seems that there is, green ants are newly brewed with wine, red clay small stove, Bai Juyi entertains Liu Shijiu, can't he just drink bar?"

"So, it's fake?"

"It can't be said to be false, I guess he asked the boatman how long it would take us to get to Gangneung at our speed, and they told him that it would be enough in one day, and he wrote this poem according to the time of the day. There must be a pot on the ship, and the boat pot should also be a relatively simple hot pot. ”

Thinking of the scene of Li Bai eating hot pot and drinking wine on the boat, and taking the boat down the river, Lu Ping couldn't help but be fascinated:

"Well, Li Bai's personality is very unrestrained, so his poems often use exaggerated rhetorical devices...."

Lu Ping looked at Li Yiming, this comrade took Li Bai as an example when he was in class at the Hangcheng Hotel, saying that the story of the iron rod grinding needles was made up blindly.

Well, it's a nonsense, and someone will have to check this thing in the future. Lupin could even help with checking how to write.

"Li Bai is quite romantic... But let's not just stop here, or else..."

Li Yiming said lightly, "A bridge flies north and south, and the moat can only be an exaggeration and rhetorical technique." ”

“......”

"When you read the poem, did you ever think that we could do it, and set up a shortcut directly in the middle of the river? Li Yiming stared at the map.

"But if you do that, you can easily get hit by a boat, and it will be dangerous if there is a flood. ”

"You're right, but this can be solved, by the way, to solve the problem of non-standard shipping, do you really think it's efficient to run a ship casually?"

“......”

"The concept of graded reservoirs has been around for a long time, right?" Li Yiming asked lightly.

Lu Ping nodded: "Yes, in fact, I want to repair the Three Gorges Reservoir, but I have been discussing, the chairman has said before that it is all about the battle, you... Are you saying it's possible?"

"Don't be greedy, this kind of only one repair is not good, if you want to repair it all the way down from the upstream, all the tributaries have to be repaired, not to build a reservoir, but to build a lake to drain the water, reduce the danger. ”

Lupin reached out and took his notebook to remember: "What is the difference between building a reservoir and building a lake to drain water?"

Li Yiming looked at Lu Ping: "Don't remember, I'll give you a plan tomorrow, I haven't seen the upstream survey data yet, and I can't make it up if I want to." ”

Lupin sighed, he didn't know why something was sent so slowly: "Maybe I'm worried about your body." ”

"I'm worried that I'll give less information? Then I don't want to think about it? If you don't give it, I'll have to deduce it myself, and it will take a lot of brains!"

"Uh...."Lu Ping looked at Li Yiming tightly, you still speculated on the topography of the country yourself?

We are looking at the same map, I think of 9.6 million square kilometers of land and vast things like a rooster, but you are deducing how the hydrogeography of these mountains and rivers can move mountains and reclaim the sea......
