Carrying AK into Ming Dynasty

Chapter 187 The Importance of Mathematics

Liu Hongjian took Uncle Song around for a long time, until it was getting dark, Song Yingxing still couldn't get enough of it.

There is no oppression, no exploitation, no domineering officials, and no sneering and cruel officials. There are only a bunch of energetic and enthusiastic colleagues or comrades-in-arms.

This place is simply a paradise for craftsmen, and he likes it so much.

The three of Yan Yingyuan left, except for him who often comes to supervise and inspect, the people who talk about here are Fang Jingzi, who doesn't like to talk, and Chang Yu, who plays a guest role.

Liu Hongjian summoned the foremen selected by craftsmen at all levels, officially announced that Song Yingxing would join the Ordnance Institute, and appointed him as the second-stage head of the Ordnance Institute, who was fully responsible for many research projects of the Ordnance Institute.

Amidst the applause of a bunch of people, Chang Yu and Fang Jingzi also breathed a sigh of relief.

Facts have proved that some people are only suitable for the army, and some people are only suitable for doing things. If you want to coordinate such a large number of people without making mistakes, you really can't do porcelain work without diamonds.

On the way back, Song Yingxing was overwhelmed with emotion. It has been many years, time has worn away his heart of serving the country, and the corrupt officialdom has pierced this heart full of holes.

And the Lord Marquis in front of him, who was deeply trusted and favored by the Holy One, and the armory station that looked like a paradise not far away, ignited his heart again, and now he is full of strength.

He's going to have a big fight!
"Master Hou, when the old man returned home, he wrote to his family, asking his two dogs to come.

These two incompetent things know nothing else, they can farm, and their research on crops is even higher than that of the old man. I think the two of them can help Lord Hou take care of potatoes and sweet potatoes! "

Song Shihui, Song Yingxing's two sons, Song Shiyi was influenced by him since childhood, and was obsessed with farming since childhood.

"This couldn't be better. Mr. Song is full of talents, and this time I really got a big deal!" Liu Hongjian was really happy, and he could be the shopkeeper again.

"Mr. Song, do you think our ordnance station needs improvement?" Although Liu Hongjian claimed to be very humane, he still wanted to hear Uncle Song's opinion.

"Your Majesty's way of doing this has improved the enthusiasm of these craftsmen, this is a good way!
But enthusiasm is not enough for craftsmen. Does Lord Hou know what is the most important thing in making muskets and cannons? "Song Yingxing frowned slightly and said.

"Well, I think the most important thing is pig iron. Only by refining good iron can the guns produced be less likely to blow up and have a longer service life!" Liu Hongjian didn't quite understand this, but said according to his own understanding. .

The carriage was driving on the slightly bumpy pipeline, and the two of them didn't mind the cold weather, so they talked happily in the carriage.

"Hou Ye is indeed a knowledgeable person, but good iron is of course important, but it is not the most important.

For artillery, one is accuracy, and the other is range. No matter how strong the cast artillery is, if it hits close, it will be useless if it is not accurate! "

"Well, what Song Lao said is right!" Liu Hongjian could only chatter.

"The range is not easy to improve at present. Our Ming's Hongyi cannon can shoot far, but it is extremely heavy and can only be used for city defense, but I do have some research on this accuracy."

The Hongyi cannons of Ming Dynasty cost several tons, even more than a dozen tons, and their firing range is proportional to their volume.

There is no other reason. The purity of the gunpowder is not enough. If you want to shoot far, you have to put more gunpowder. If you want to put more gunpowder, the gun body will not explode.

It can only be thickened, bolded and lengthened!
"Did Song Lao mean the front sight? It is the object that can be used for aiming on the artillery."

The artillery that Liu Hongjian saw when he was guarding the city was only a round barrel. Even the old artillerymen of the Shenji Battalion needed multiple proofreadings if they wanted to accurately hit a place. Proof again.

At this time, the guns are all front-loading guns, and the speed of reloading is super slow, wasting the first shot, which is almost fatal on the battlefield.

Experienced ones are fine, but ordinary artillery basically rely on sniping, or simply use artillery tactics, which is fine in defending and attacking a city. After all, the target is big, and you can always gain something by hitting casually.

But in a naval battle, the warships of both sides are moving targets, so it won't work.

"Yes, Lord Marquis. A few years ago, this old man was lucky enough to go to the warship of the Francobots. Their guns all have front sights. Afterwards, this old man thought about it for a while at home, but he hasn't tried it yet!"

It is a capital offense to build cannons privately, and he has only scratched the surface in some fields. Fortunately, Lord Hou has no taboos here. Song Yingxing plans to start researching it in the near future.

"There is one more thing that Mr. Song needs to worry about. The current craftsmen rely on experience and estimates. It is okay to make furniture and the like. If it is used in the military, the pass rate is too low.

I think it should be quantified!I don't know what Song Lao wants to do? "

This can be regarded as a tradition of the Chinese nation. Just like stir-frying and cooking, the chefs never say how many grams of salt and how many milliliters of soy sauce should be added. It is always a little salt and an appropriate amount of soy sauce.

How much is a little?How much is the right amount?

If you ask cooking chefs, they don’t know either!They'll just tell you that it's the experience!

"Don't worry about this Marquis. The old man has improved the copper ruler I used in my work. The accuracy has doubled compared to the current copper ruler. After a while, the old man will start to teach these craftsmen!"

The copper ruler Song Yingxing mentioned is the predecessor of the vernier caliper in later generations. In fact, as early as the Eastern Han Dynasty, the smart Chinese invented the caliper. Although the accuracy is not very high, it is thousands of years earlier than Europe.

There is another thing that Liu Hongjian has always worried about, and that is mathematics, which is arithmetic if it is down-to-earth. A considerable number of those craftsmen are illiterate, which is a big problem.

Moreover, Daming's counting method is too cumbersome, whether it is the uppercase one two three four or the lowercase one two three four, it is very inconvenient.

Both vernier calipers and precision are closely related to mathematics.

It seems that I have to work hard to compile a primary school mathematics textbook when I find time!They have to hire a master to teach them how to read!

It's all about things, why do I feel like I'm a nanny!
The two returned to the Hou Mansion with their own thoughts on their minds, and Song Yingxing went back to his room to write letters to his family.

And Liu Hongjian, who was exhausted all day, also sneaked into Yang Xue's room.

Yang Xue was learning how to make tiger-toed shoes at home, when she accidentally got hugged by Liu Hongjian.

"Master is back! Are you tired! Xue'er will pour you tea." Yang Xue stood up happily and tried to break free from Liu Hongjian's strange hand.

"I'll talk about it later, my master has a deal worth hundreds of millions of dollars to discuss with my Xueer, come quickly!" Liu Hongjian said while sitting by the bed mysteriously.

……

Two quarters of an hour later, Liu Hongjian hugged the greasy little fairy panting heavily.

"Master, the concubine went to the palace with the master for a banquet yesterday, and found something interesting." Yang Xue lay on Liu Hongjian's chest, feeling her husband's strong heartbeat.

"What?" Liu Hongjian yelled in his heart that he could not take it anymore.

"His Royal Highness, Princess Kunxing, always secretly looks at the master from time to time!" Yang Xue secretly put her small mouth in Liu Hongjian's ear and said with a smirk.

Ah~~~? ?
