It is definitely necessary to liberate women’s productivity!
Because the war caused a large number of men to decrease, if women did not come out to work, it would be difficult for social productivity to recover quickly. This was not only the case in the late Ming Dynasty, but also in modern times.
After liberation, in order to increase productivity, didn't our country also shout the slogan "Women hold up half the sky"?
Li Daoxuan knew that the current Ming Dynasty relied on his own golden fingers to provide food and materials, and the productivity problem was not bad. If one day due to some accident, he stopped helping, the world in the box that had just experienced the war would need men and women. Come out together and try to restore productivity.
Men alone are definitely not enough! After the war, how many men will be left?
So now he is throwing a wave of chicken soup in advance to plant a seed of "liberating the mind" in women's hearts. This is also necessary. Give them some time to grow slowly.
"Yiye, come here.
Gao Yiye knew that he had to convey the message by himself, so he quickly ran out of the cloth village, followed Li Daoxuan's instructions, came to the school, went straight to the fifth floor, and came to the library.
The atmosphere in the library was as chaotic as ever, with manuscript papers flying everywhere.
But Mr. Bai is not here today, only Song Yingxing is here.
Mr. Bai is now about to start giving "physics classes" to the children. Some of the children who are learning quickly have already completed "primary school mathematics" and have now entered the "junior high school" level, and can start learning "physics". ", Mr. Bai naturally can't do strange things with Song Yingxing in the library every day.
When Gao Yiye walked into the library, Song Yingxing was lying on the ground with his butt sticking out, writing and drawing on a huge piece of paper.
Li Daoxuan took a closer look and found out that what he drew was an "electric train".
"This is unscientific!" Song Yingxing shook his head as he drew: "This thing is absolutely unscientific. It is impossible for it to run. Its mass will cause it to disintegrate. How can it possibly run?"
Li Daoxuan smiled: "Tell Mr. Song that it was conjured by my immortal magic and does not obey physics."
Gao Yiye spoke.
Song Yingxing shouted "Ah" and jumped up from the ground: "My Lady Saint, when did you come?
Gao Yiye: "I've been here for a while, and Tianzun has been here for a while. I saw you drawing something, so I didn't bother you.
Song Yingxing looked embarrassed: "Ahem... I'm very interested in this electric train, but unfortunately... it can't be built by studying physics."
Gao Yiye smiled: "Tianzun is an immortal. Immortals follow 'divine principles', not 'physics.'" "
Perfect explanation!
Song Yingxing was no longer confused: "What does Tianzun want from me?"
Li Daoxuan: "Do you know how to make the Hongyi cannon?"
Song Yingxing was stunned: "I know this, but...why did our village build this? This is a firearm used in large-scale battles or sieges. If we just fight off bandits, we have fire guns and grenades." .
Li Daoxuan: “It’s good to make it for fun, whether it’s useful or not, it’s good to make it for fun and study the technology.
No one would believe this, but Song Yingxing had no doubts because he himself liked to make all kinds of messy things for fun.
He took out a piece of paper, picked up the pen, and brushed it. It didn't take long to draw the method of making the Hongyi cannon on the paper.
Li Daoxuan didn't say anything, but Gao Yiye couldn't help but marveled: "Mr. Song, how many strange things do you know? Why can you draw drawings every time I come to you?
Song Yingxing said: "Being able to draw these drawings is not a big deal. These are things invented by others. I just copied their inventions. It's not great at all. What if I could invent something interesting on my own? well.….
At this point, he felt a little sad: "What I want to invent most now is the little train. It would be great if we could use the power of mortals to make the little train that Tianzun conjured using immortal magic. It would be great. It's a pity. Yes, I can’t think of any way to move such a huge car.”
Hearing what he said, Li Daoxuan's heart moved. Are you thinking about this?
This is indeed a bit early for the late Ming Dynasty.
With the technology and productivity of the late Ming Dynasty, let alone building a train, even if there were a train, the materials for laying the rails would not be solved. With the mining technology of the Ming Dynasty, how could it be possible to mine so much iron to lay a long track? Railway?
Fortunately, I am here! Just put a few lumps of iron in and it would be enough for them to lay a railway from Australia to the Maldives.
Steam trains now have enough technology to make them, but if he directly provided the drawings, Song Yingxing would have "copied" them instead of "inventing" them. This is not good for scientific inspiration.
Simply give him only one core and let him imagine the other things.
Li Daoxuan rummaged through his pile of toys, and soon found an interesting little thing, a "miniature steam engine." This thing was bought from a certain store. It cost only a few dozen yuan and was only a few centimeters tall. .
He simply placed the thing directly on the rooftop of the teaching building: "Yiye, take Mr. Song up to the rooftop and show him a small thing."
Song Yingxing climbed up to the rooftop as instructed, and saw at a glance a huge machine with water pipes and strange big wheels on it...
Li Daoxuan poured some water into the water pipe in front of him, and then lit the alcohol beaker under the water pipe.
A ball of flame jumped up and burned the water in the water pipe. It didn't take long for the water to boil. The steam rushed out along the pipe and drove the big wheel, which began to spin crazily.
Li Daoxuan smiled and said: "Do you understand?
Song Yingxing watched with fascination: "I seem to understand, understand... This is what was taught in physics class. Water is heated and turns into gas. The gas is compressed in a small space, so It generated a lot of force and pushed the big wheel to spin.
"That's right!" Li Daoxuan: "This is a steam engine. Its principle is very simple. You will understand it at a glance. If you use a steam engine, you can drive wheels. As for wheels, you have already learned the principle of gears. Using gears By driving the gear, the power can be amplified several times."
Song Yingxing seemed to understand something: "I understand, I understand, hahaha, I understand this time. As long as there is enough steam and enough wheels, I can move very, very heavy things."
Li Daoxuan: "That's right, keep researching. With your intelligence, try to see if you can use this principle to invent something."
