The guard on duty in the courtyard of Li Shouhan's signing room frowned and looked at the three rooms outside the signing room with a wry smile.

These three abodes were originally the reception room and dining room used by Li Shouhan to entertain guests.Needless to say how exquisite and gorgeous the decoration appliances are, there is even a surprise design inside.The three rooms are separated by high-quality hardwood carved partitions.If there are too many guests, the partition door will be opened, and it will be a quite spacious hall.

In the hall, more than a dozen tables were spliced ​​together by the guards to form a long table.Dozens of gentlemen on both sides of the table are usually good teachers and gentlemen. At this time, their faces were flushed when they were arguing. The originally clean floor in the room was covered with paper scraps. black dot.

If someone else saw such a scene, I'm afraid they would have been furious.However, Li Shouhan himself, who was sitting in the corner with a carved glass tea cup and sipped the frozen top oolong sent from Taiwan, laughed like a flower in his heart.

"Today I can be considered to have experienced what it means to have all the heroes of the world in my pocket!"

When Galileo and others were led here by Uchiyama Yongming, Li Shouhan had already brought He Yingguan who was in charge of developing the breech-loading gun, his official name was He Wusheng, and a dozen heads of craftsmen made by Hejing in the abbot. There has been a quarrel.

Seeing that Galileo led a group of top mathematicians and physicists of this era to arrive, Li Shouhan couldn't help but smile. "The old man is here? Hurry up! He Lao Wu, introduce the situation of this firecracker you designed to a few gentlemen, and ask them to give you a careful calculation. The cannon fire is the closest!"

He Wusheng pretended to be modest and ordered his subordinates to remove the white cloth covering the drawing board, revealing the design drawings on it.At the same time, he lifted up the red silk covered with a long tray on the table.Show the prototype gun in front of these ten big bulls.

It is a little different from the traditional meticulous drawing patterns that are popular in the Mainland. In the Southern Guangdong Army, the three-sided graphic drawing of Kaiping vertical section has been implemented to design drawings according to the scale, and it has been extended to industrial manufacturing and the construction of houses, bridges, docks, and docks.Although this kind of drawing cannot be seen by adults, it is very convenient for craftsmen.It is also much more accurate, compared to the kind of artifact pictures whose artistic quality is far stronger than scientific practicality, but it is much stronger. (You can imagine what the industrial design drawings drawn by art students would look like.)

The gun designed by He Wusheng is quite in line with Li Shouhan's requirements. Moreover, the prototype gun has also been demonstrated by soldiers, which is quite in line with the deep ditch and high fortress against the Liao thieves proposed by everyone at the battle summary meeting. The tactical needs of the long trench bunker.

One of the biggest advantages of this gun is that it can be loaded in a prone position!

A standable chamber made of iron-barred steel.There is a constriction in front of the chamber, which can be inserted into the back of the chamber. After the propellant explodes, the constriction expands, and the closed gas leaks from the breech. It is actually a metal cartridge case fixed on the gun.The soldiers used the cardboard fixed-load ammunition commonly used by the Southern Guangdong Army, which could be easily loaded in a prone position.Moreover, because it is breech loading, the steps between the solid projectile and the propellant charge are eliminated with a cleaning rod.It has also improved a lot of speed, almost standing up and loading three rounds.The prone position can load four to five rounds.However, the barrel may not be able to withstand such frequent firing, and the hot barrel does not allow such continuous and intensive firing.

Several Guards Brigade officers who heard the news also snatched the prototype gun from the soldiers with great interest and took it into their hands to examine it carefully. With the help of the craftsmen, they began to familiarize themselves with the new gun with great interest. .

The loading method is completely different from the previous firecrackers, which immediately opened their eyes.

"One, open the hammer under the chamber!"

"Second, turn the crank on the right side of the gun to turn the chamber outward!"

"Third, check the fire door at the bottom of the chamber!"

"Fourth, pour the propellant in the paper shell into the chamber. Finish loading the propellant!"

"Five, insert the warhead!"

"[-]. Turn the crank, return the chamber, insert it into the barrel, and complete the lock!"

Under the orders of the craftsmen and soldiers, several officers of the Guards Brigade simply joined the soldiers in charge of the experiment.Take a prone position for loading, simulating the full set of actions of loading and launching arrows and projectiles fired from trench fortifications facing Liao thieves and other enemies.

Sharp-eyed students may have already seen that this new gun designed based on the principle of the Franc machine's sub-gun is basically the same as the Kammerlader m1842 model that appeared in history. The difference is that, Compared with the Carmelite gun, the firing originally done by the cap is still done by flint.Moreover, it has also changed from the rifled barrel of the Carmel Ryder gun to the smoothbore.

Historically, the Kamer Ryder gun was considered a rather sad rifle. When it was installed, the Dresser firing needle gun had already appeared, and the output was very low. There were dozens of improved models in total, but the output was only more than 4 As for the scope of the armed forces equipped, only the Norwegian army and navy and the Swedish navy are equipped.

However, being born at the wrong time does not mean that the performance of the Carmel Ryder gun is not good.On the contrary, its unique design and loading method compared with the Dresser firing pin gun, although the speed is slow, but basically solves the problem of breech air leakage, so that the accuracy and range of the Carmel Ryder gun are much better than Dreiser needle gun. In 1861, Belgium held a shooting competition of high-precision military rifles, and the results proved that the participating Carmel Leder m1860 was one of the most accurate rifles at that time.Carmel Ryder guns used spherical bullets in the early days, and later used conical bullets. After 1855, all models switched to Mini bullets.

Right now, the new gun that He Wusheng took out is the monkey version of the Kamerlader gun that he tinkered with based on the ideas in his mind and Li Shouhan's hints to him.

The percussion is changed to flintlock, and the rifle is changed to smoothbore.The only thing that hasn't changed is the miniature bombs are still used.

Mini bombs are not technically difficult, they are just projectiles anyway.Simply one step in place.

However, once the prototype gun is available, it may not be able to equip the troops immediately.There are still many situations that need to be improved.Before the arrival of Galileo and others, Li Shouhan had already had a good discussion with the people present on the finalization of the size of the new firecracker.

Although there is no concept of ergonomics in this era, there is also a standard for whether a weapon can be used comfortably and by the most people. In order to best play the performance of this firecracker, Li Shouhan specially called Seven or eight doctors came and asked them to comment on the size of this firecracker from the doctor's point of view.Find the best size from it, so that the soldiers can play the best performance indicators of this firearm.

As for why Galileo and others were summoned overnight and made the old man uneasy all the way, it was to give full play to the ingenuity and academic attainments of these mathematicians and physicists, and to add some technological additional means to this gun.

"How to calculate the most suitable wall thickness of the gun barrel, so that the gunpowder can send the projectile farther, hit it more accurately, and prevent the gas from leaking after the gunpowder is fired. These are the questions I set for you. You may wish to study carefully here.”

As a result, Pask, Torricelli, Fermat, Malan Mason, Gassendi, Desargues and others immediately fell into the state of a free country of academic discussion. From the perspective of outsiders, they were basically a group of lunatics.

From the length of the gun barrel to the range of the shot, these scientists quickly had a direction.

Next, calculate the amount of gunpowder based on the maximum range to be achieved.Based on the amount of gunpowder, calculate the moment when a sharp burn begins.The maximum pressure borne by the gun tube, and based on this data, calculate which alloy to use from a metallurgical point of view, in order to thin the tube wall to the maximum extent, reduce the thickness of the gun tube, and make the whole gun lighter Some.

The pen in his hand kept calculating on the white paper.Leaving behind scribbled calculation formulas and results, but kept arguing fiercely with others, sometimes pointing at each other's noses and yelling, attacking each other's poor academic attainment, and so on.

In the room, there was a constant wave of noise mixed with various languages, and there were bursts of green smoke constantly wafting out from the doors and windows. (That's the result of a few heavy smokers constantly puffing.) People who don't know the inside will mistakenly think that there is a fire here, and the people inside are scrambling to escape.

Naturally, such an almost epoch-making scientific research project cannot be completed in a one-and-a-half-day meeting. Being able to find ideas in a day's discussion is already a remarkable achievement.After a long while, Li Shouhan saw that everyone was no longer noisy and their voices gradually became lower. He knew immediately that everyone's physical strength and energy had reached their ebb.Seeing that it was already the time for the sun to set, Li Shouhan patted his hands lightly a few times: "Everyone, I will come here first today. I have set up a simple meal in the mansion. Please work hard after the meal." That’s right. If you can’t finish the work, you might as well take it back as a research topic.”

After Li Shouhan said this, Uchiyama Yongming and others who were waiting on the side came out to dissuade these scientific madmen who had already fallen into how to overcome the problem at hand to put down their scientific exploration for the time being, and left the table to have dinner in the flower hall outside.

"Tell the soldiers, don't touch the paper I put on the table! Don't mess up my records and calculations!"

"That's it! And my design sketches!"

A few guys were dragged away from their seats half-asked, and while walking, they were still yelling not to touch the calculation results they left on the table.

"Yongming, bring your precious son too! Didn't he always say that elementary school mathematics textbooks are too simple and boring? These gentlemen are all the most accomplished in mathematics in my Southern Guangdong Army and even in the whole world, and they are all from the academic world. The top person, Taishan Beidou! I don’t see you now, when will you be here?”

Li Shouhan laughed and teased Uchiyama Yongming a few words, and signaled the soldiers around him to go to Uchiyama Yongming's residence to bring his second son, Xiaoxin, to have dinner with him.

What an honor and reward is it to have dinner with the lord?What's more, there are almost the highest-level academic leaders in the Southern Guangdong Army.His own son who just entered primary school was able to enter the eyes of the lord, and Uchiyama Yongming almost fainted from happiness.

I used to sell a trick before, asking everyone to guess the identity of Uchiyama Nagaaki. I wonder how many of you guessed it right?That's right, although he is not well-known, he is his second son, Xiaoxinzhu, who later adopted someone else's surname Guan.But it is Guan Xiaohe who has left a famous figure in the history of mathematics.The founder of the Hesuan system improved the Tianyuanshu algorithm in Zhu Shijie's "Enlightenment of Mathematics", created the unique pen algebra of Hesuan, established the concept of determinant and its preliminary theory, and perfected the digital equation introduced from China approximate solution.Discovered the conditions for the existence of positive and negative roots of the equation, studied the Pythagorean theorem, ellipse area formula, Archimedes spiral, and pi, and initiated the research on "circle theory" (the infinite series expression of the relationship between diameter, arc, and vector) , magic square theory, continued fraction theory, etc.At the same time, he has also written several works on astronomy and calendar, including four volumes of "The Establishment of Time-serving Experience", "The Establishment of Time-serving Experience", "Invention of Time-serving", "Siyu Algorithm", and "Xingyao Algorithm".

(The birth date of Guan Xiaohe has always been controversial in the historian circles. There are two versions of the date of birth. The first is that he was born in Edo Koishikawa in 1642. The other is that his father was born in Ueno Fuji in 1637. Gang. But in order to lay out the plot, this factor is temporarily ignored, let’s let Guan Xiaohe have already attended primary school in Hue!)

In fact, when Li Shouhan summoned these experts today, in addition to giving them a new scientific research task, he also had to entrust them with the task of building a nationally important weapon.

Not long ago, he approved Zheng Zhibao's and Zheng Sen's uncle's and nephew's submissions on the rapid deployment of primary school teachers in Java and other places, and the popularization of compulsory education in large quantities, and how to further strengthen education and various vocational personnel training on the basis of Nanzhong's basic set.He put it on the agenda.He and Li Peilin have discussed this matter several times.

In addition to continuing to popularize six-year compulsory primary school education in the new district.Li Shouhan even planned to promote middle school education in Ha Tinh, Hue, Chai Gun, Jiulong River, and Chao Phraya River.

The promotion of primary school education in the new district can quickly complete the assimilation of school-age children within a few years, allowing them to achieve cultural identity. After having a primary school education, they can become qualified laborers everywhere, even if they are working at home.It will also be much better than the general illiterate to master the promotion of new farm tools and agricultural varieties.

In the battle report sent by Java, Zheng Sen wrote very proudly that although the chaos in Java was suppressed this time, although the territory was not expanded, the population under direct control has invisibly increased by millions.With these millions of people.The labor shortage situation will be temporarily alleviated.

"For six years in primary school, even if I raise these children with rice and stewed meat, it is better than mobilizing a large army to conquer! The military expenditure is much more than the education expenditure! Moreover, this is for Laozi to train labor! One in and one out, unless I was kicked in the head by a donkey, so I chose to use swords."

However, popularization of secondary education is not like that of primary education.

According to Li Shouhan's initial idea, vocational education and academic education should be combined.In addition to the subjects already available in elementary school, the curriculum should also include physics, algebra, geometry, etc. Otherwise, he would not order people to get various mathematics and physics books from Europe at any cost.

However, if I ask myself, most of the junior high school mathematics that Li Shouhan learned back then has been returned to the teacher.How to compile teaching materials and how to train teachers depends on these people in front of us.

Since he was in charge of the family, whether it was a tiny place in Ha Tinh, a general's mansion in Hue, or Uncle Ning Yuan certified by the Ming court, Li Shouhan has consistently implemented one principle, that is, talent training must go In front of technical equipment!Absolutely not to be Zhuge Liang who is prophetic, but to be a farmer who sows seeds.

When you plant ideas and knowledge into other people's minds, these seeds will naturally take root and germinate slowly, and then there will be no shortage of new technologies, new machines, and new production processes.The point of view that as long as there are advanced technology and equipment can conquer the world, but it has been verified in history, this way is not feasible!

Whether it is the Soviet Union built on the ruins of the October Revolution, or Germany, which has swept across Europe with an army of [-] and almost fought against industrial powers all over the world without falling behind, they are all under extremely difficult circumstances. , Cultivate talents first, let talents wait for equipment, not let equipment wait for people.

Think about those German Army officers who sat in cardboard boxes to simulate the impact of tank units, those Bolsheviks who built steel factories in the mud along the Dnieper River, and look at the machine warships and sophisticated guns that thought they had money to buy foreigners. The bureaucrats of the Westernization Faction who can achieve Tongguang ZTE, as well as those local tyrants in the Middle East who suddenly became rich sitting on the oil fields relying on the generosity of nature, let’s look at those domestic steel mills that were forced to fight in the war of resistance in order to get kickbacks. Li Shouhan, the official of the Cannon Party that went bankrupt in the flames of war, gritted his teeth, "My conditions are much better than theirs! No matter what, I can't be a Cannon Party and a Westernization Sect!"

Sure enough, the problem of being a good teacher is not only my Chinese people, but this group of red-haired barbarians from Thailand and Western countries is even worse.Hearing that His Royal Highness Li Shouhan, Duke Li declared that he would create a middle school education system between the primary and university stages, and asked them to be responsible for compiling textbooks and cultivating middle school teachers, even the young Pascal blushed with excitement. Stop rubbing your hands.

"His Royal Highness, when will it start?!"

Standing outside the gate of the palace, watching the drunken Galileo and others' carriages and horses leave, Li Shouhan, whose face was flushed from the fumigation of alcohol, carried his youngest son in his arms, "Come on! How about this important national weapon that you and your brothers and sisters built?"

Li Huacheng, who was a little drunk from the smell of alcohol on his father's body, just giggled, but his mother, Ao Lei Yilan, couldn't stand it anymore.

"A suckling baby, what important weapon does a country know?! Let them settle the matter of the new blunderbuss first!"

well!It seems that he is another person who thinks that the country's most important weapon is an epoch-making weapon!

Li Shouhan sighed in his heart. (To be continued..)
